The pairs of ribs 55 are regularly arranged at preferably equal intervals on the side walls 19, 21 in the container receiving area 25, preferably between the guide elements 31, 33 and the upper limitation 19.

[0594] The dosing device 29 is designed for dosing the baby food concentrate from the first container 9 from the second container 11. The dosing device 29 can be connectable to the first container 9. Thus, the dosing device 29 can be connected to the first container 9, so that the dosing device 29 in the state connected to the first container 9 can be introduced or received into the first receiving area 5 by a movement that is essentially perpendicular to the rear wall 13 of the first receiving area 5.

[0595] The dosing device 29 comprises a screw conveyor 57 and a screw conveyor housing 59, which are shown in FIGS. 5 to 7. As shown in FIG. 8, the screw conveyor 57, preferably in its full length, can be inserted into the screw conveyor housing 59 and rotatably arranged therein, so that the screw conveyor 57 and the screw conveyor housing 59 extend around a common screw conveyor longitudinal axis 61. The following describes the features of the screw conveyor 57 and the screw conveyor housing 59 in relation to the common screw conveyor longitudinal axis 61, even if the screw conveyor 57 is not inserted into the screw conveyor housing 59, as shown in FIGS. 5 to 7.

[0596] The screw conveyor housing 59 has an inlet 63 with an inlet opening 35 and/or an outlet 67 with an outlet opening 69. The inlet 63 and the outlet 67 are arranged in the screw conveyor housing 59 on opposite sides, seen transversely to the longitudinal axis 61 of the screw conveyor. The screw conveyor housing 59 extends between a first end 71 and an opposite second end 73 along the longitudinal axis 61 of the screw conveyor. The outlet 67 is disposed adjoining or near to the first end 71 and the inlet 63 is disposed adjoining or near to the second end 73.

[0597] The inlet 63 comprises in particular a flange 75 with a peripheral wall 77, the peripheral wall 77 at least partially surrounding the inlet opening 65 and/or extending essentially radially to the longitudinal axis 61 of the conveyor screw away from the screw conveyor housing 59. As FIG. 6 shows, the peripheral wall 77 extends essentially along a first peripheral wall central longitudinal axis 78. The peripheral wall center longitudinal axis 78 can in particular have a length of approximately 47 mm. Furthermore, the peripheral wall 77 extends along a second peripheral wall central longitudinal axis 80, which is oriented at an angle different from 0° or 180°, in particular transversely, preferably perpendicular to the first peripheral wall central longitudinal axis 78, and in particular can have a length of approximately 29 mm.

[0598] The flange 75 is designed for connecting the dosing device 29 to the first container 9 and/or for introducing the dosing device 29 into the dosing device receiving area 27. Thus, the peripheral wall 77 comprises a first contact surface 79 and a essentially opposite second contact surface 81, the first and second contact surfaces 79, 81 being aligned parallel to each other. These contact surfaces 79, 81 enable the dosing device 29 to be introduced into the dosing device receiving area 27 in a particularly simple manner. In particular, during insertion into the dosing device receiving area 27, the contact surfaces 79, 81 can slide essentially along the guide elements 31, 33 in the first receiving area 5 and/or, after being received in the dosing device receiving area 27, can essentially rest against the lateral guide elements 31, 33.

[0599] The screw conveyor housing 59 in particular has an outer wall 83 with a plurality of ribs or screw conveyor housing ribs 85, the ribs 85 preferably extending in the axial direction at least partially between the first end 71 and the second end 73 of the screw conveyor housing 59. The ribs 85 extend away from the outer wall 83 essentially in the radial direction as seen from the longitudinal axis 61 of the conveyor screw.

[0600] Two of the ribs 85, as the first pair of limiting ribs 87, limit the outlet opening 69 of the screw conveyor housing 59 on opposite sides in the peripheral direction of the outer wall 83. Two further ribs 85, as a second pair of limiting ribs 89, limit outlet opening 69 on opposite sides in the axial direction of outer wall 83. This configuration prevents baby food concentrate from coming into contact with the first receiving area 5, which, in contrast to the dosing device 29 and the container 9, cannot be exchanged.

[0601] The conveyor screw 57 has a drive end 82 in the direction of the conveyor screw longitudinal axis 61. From or at the drive end 82 of the screw conveyor 57, a coupling device 91 extends essentially along the longitudinal axis 61 of the screw conveyor, the coupling device 91 being designed to interact, in particular to intervene, with the actuating and/or drive device 39 or with the drive shaft 41.

[0602] The coupling device 91 can be designed as an essentially cylindrical cavity 93 or as a receptacle, so that after the introduction and at least partial inclusion of the dosing device 29 in the dosing device receiving area 27, the coupling element 41 in the dosing device receiving area 27 is at least partially received in the (cylindrical) recess 93 can be. The inner wall 95 of the (cylindrical) cavity 93 preferably has an inner profile which can be brought into engagement with an outer profile of the outer wall 96 of the coupling element 41. The outer profile of the coupling element 41 has at least one material elevation 97, which can engage or interact with at least one material recess 99 in the inner profile of the cylindrical cavity 93. Thus, the coupling element 91 is designed as a drive shaft, so that the introduction of the coupling element 41 into the (cylindrical) cavity 93 enables the dosing device 29 to be driven and thus the screw conveyor 57 to rotate.

[0603] The screw conveyor 57 is preferably designed as a shaft around which one or more helically wound flights 101 in the form of flat guide surfaces or sheets or rubber flaps are wound, which extend in the form of a screw thread 107 transversely away from the longitudinal axis 61 of the conveyor screw.

[0604] FIG. 8 shows the dosing device 29 inserted and received by the dosing device receiving area 27 in the first receiving area 5 of the device 1 for preparing baby food. The screw conveyor 57 preferably extends inside the screw conveyor housing 59, the coupling element 41 on the rear wall 13 being inserted into the cylindrical cavity 93 of the screw conveyor 57 and/or being able to drive it. Baby food concentrate that is introduced into the interior of the screw conveyor housing 59 through the inlet opening 65 can be guided along the one or more helically wound flights 101 essentially along the longitudinal axis 61 of the conveyor screw to the outlet 67 and/or through the outlet opening 69 the interior of the screw conveyor housing 59 leave. An insertion element or removal element 105 is preferably arranged on the second end 73 of the screw conveyor housing 59.

[0605] FIG. 9 shows a front view of the dosing device receiving area 27 with the dosing device 29 inserted. In the state inserted into the dosing device receiving area 27 of the first receiving area 5, the lateral contact surfaces 79, 81 of the peripheral wall 77 of the dosing device 29 and two of the ribs 85 rest on the two guide elements 31, 33. In particular, the abutment surfaces 79, 81 can abut the edges 107 of the guide members 31, 33 extending away from the side walls 15, 17, and the two ribs can abut the undersides 109 of the two guide members 31, 33 facing the lower limitation 21.

[0606] With reference to FIGS. 10 to 14, exemplary embodiments of the first container 9 for receiving and/or for dosing baby food concentrate are described.

[0607] As can be seen from FIG. 10, the first container 9 can have a housing 111 having an interior space 112 for receiving baby food concentrate and an outlet 113 in fluid communication with interior space 112. The first container 9 is designed to be introduced and/or received at least partially in a device 1 for preparing baby food as previously mentioned in the context of FIGS. 1 to 9.

[0608] The outlet 113 can be connected to an inlet of a dosing device 29, which comprises a screw conveyor 57 and a screw conveyor housing 59, the screw conveyor 57, preferably in its full length, being inserted into the screw conveyor housing 59 and arranged to be rotatable, so that the screw conveyor 57 and the screw conveyor housing 59 extend around a common longitudinal axis, the conveyor screw longitudinal axis 61. The outlet 113 of the first container 9 can be connected to the inlet 63 of the screw conveyor housing 59, the screw conveyor housing 59 having an outlet 67, so that by actuating the dosing device 29, a predetermined or predeterminable amount (or dosage) of baby food concentrate through the outlet 67 is delivered through. The outlet 113 of the first container 9 can be screwed or glued to the inlet 63 in the screw conveyor housing 59, or the inlet 63. The screw conveyor housing 59 can, however, also be integrated into the first container 9 or firmly connected to it.

[0609] The first container 9 can have an inlet opening 115, the inlet opening 115 preferably being arranged essentially opposite the outlet 113 and/or an outlet opening 117 in the outlet 113. The inlet opening 115 can be closable by means of a closure element 119, preferably by means of a zipper or zip. The closure element 119, preferably the zipper, is designed to be inserted at least partially into a groove in the first receiving area 5 of the device 1 for preparing baby food. A tab 121 with an inner opening 123 is arranged adjoining or near to the closure element 119. The inner opening 123 can serve as a handle, so that the first container can be easily carried from one location to another.

[0610] As can be seen from FIGS. 11 and 12, the first container 9 at least partially has a tapering section 125, the periphery of the first container 9 decreasing in the tapering section 125 towards the outlet 113 (preferably essentially conical) or tapered.

[0611] The first container 9 can have a cross-section transverse to the longitudinal axis 61 of the screw conveyor housing 59 (seen in the state connected to the first container 9), the tapering section 125 being laterally limited by a first side edge 135 and a second side edge 137. The first side edge 135 can essentially be at an angle different from 0° or 180°, in particular essentially transversely, preferably at an angle less than 90°, particularly preferably at an angle of approximately 45°, to the plane of the conveyor screw longitudinal axis 61 of the screw conveyor housing 59 (as seen in the connected state). The second side edge 137 can run at an angle different from 0° or 180°, in particular essentially transversely, preferably at an angle less than 90°, particularly preferably at an angle of approximately 45°, to the plane of the conveyor screw longitudinal axis 61 of the screw conveyor housing 59. The first side edge 135 and/or the second side edge 137 can each have a side edge section 136 which can extend at an angle of 90° to the plane of the conveyor screw longitudinal axis 61 of the screw conveyor housing 59 (seen in the connected state). The side edge portion 136 may extend in the plane of the first side edge 131 or the second side edge 133 of the essentially symmetrical portion.

[0612] The first container 9 can at least partially have a first essentially symmetrical section 127. The periphery of the first container 29 within the first essentially symmetrical section 127 is preferably constant. The first essentially symmetrical section 127 is spaced further from the outlet 113 than the tapered section 125. The first container 9 can have a cross-section transverse to the longitudinal axis 61 of the screw conveyor housing 59 in the state connected to the first container 9, the first essentially symmetrical section 127 being laterally limited by a first side edge 131 and a second side edge 133. The first side edge 131 and the second side edge 133 are oriented essentially parallel to each other and/or at an angle different from 0° or 180°, in particular essentially transversely, preferably at an angle of approximately 90°, to the plane of the longitudinal axis 61 of the conveyor screw of the screw conveyor housing 59 (seen in the connected state). The first side edge 131 of the first essentially symmetrical section 127 can run in one plane with the first side edge 135 of the tapered section 125 and/or the second side edge 133 of the first essentially symmetrical section 127 can be oriented at an angle different from 0° or 180, in particular be oriented essentially transversely to the second lateral edge 137 of the tapering portion 125.

[0613] Adjoining or near to the outlet 113, the first container 9 can have a second essentially symmetrical section 129, the circumference of the first container 9 within the second essentially symmetrical section 129 preferably remaining essentially the same and essentially the periphery of the outlet 113 and/or corresponds to the periphery of an outlet opening in outlet 113. The second essentially symmetrical section 129 can serve as an outlet through which the baby food concentrate can be guided out of the interior space 112 of the first container 9. The side edges 139 and 141 of the second essentially symmetrical section 129 can preferably have a length of 10 to 30 mm, particularly preferably a length of 15 mm.

[0614] However, it is also conceivable that the side edges 139 and 141 of the second essentially symmetrical section 129 have a length of greater than 30 mm, preferably between 70 and 110 mm, particularly preferably 90 mm. This can be provided in particular if the dosing does not take place by means of the dosing device 29 with a screw conveyor 58 and a screw conveyor housing 59, as previously described, but if clamping elements or clamps are used to dose the baby food concentrate adjoining or near to the side walls 15, 17 in the first receiving area 5, which are designed analogously to the clamping elements 155 or brackets, which are described later in connection with the second container 11 and the second receiving area 7.

[0615] The first container 9 can have a cross-section transversely to the longitudinal axis 61 of the screw conveyor housing 59 in the state connected to the first container 9, the second essentially symmetrical section 129 being laterally limited by a first side edge 139 and a second side edge 141, which in the Is aligned essentially parallel to each other. The first side edge 139 and the second side edge 141 run at an angle different from 0° or 180°, in particular essentially transversely, preferably at an angle of approximately 90°, to the plane of the conveyor screw's longitudinal axis 61 of the screw conveyor housing 59 (seen in the connected state). The first side edge 139 of the second essentially symmetrical section 129 can run in one plane with the first side edge 135 of the tapering section 125 and with the first side edge 131 of the first essentially symmetrical section 127.

[0616] The tapered portion 125 is disposed between the first essentially symmetrical portion 127 and the second essentially symmetrical portion 129. The second essentially symmetrical section 129 preferably has a circumference that is smaller than the periphery of the first essentially symmetrical section 127. The second essentially symmetrical section 129 surrounds a volume of the first container 29 which is smaller than a volume which surrounds the first essentially symmetrical section 127.

[0617] FIG. 13 shows further, conceivable embodiments of the first container 9, which can be connected to the dosing device 29 and/or which is designed to be inserted and received in the device 1 as previously described for preparing baby food. The dosing device 29 can comprise a plate 143 which is designed as a stand plate and can be arranged on the screw conveyor housing 59 or can be connected to the screw conveyor housing 59. This stand plate 143 is used in particular to position or align the first container 9 better and/or to protect it from falling over, in particular when the first container 9 is positioned to receive baby food concentrate. It is also conceivable that the screw conveyor housing 59 has a cover 145, the cover 145 having at least one flat surface 147 which serves as a base and/or a base so that the first container 9 can be better positioned and is protected from falling over. However, it is also conceivable that the first container 9 has a further, essentially symmetrical section instead of the tapering section 125. The first side edges 131, 135, 139 of the three sections can run in one plane and the second side edges 133, 137, 141 can run in one plane, the two planes being oriented essentially parallel to each other.

[0618] FIG. 14 shows a further embodiment of the first container 9, in which one and the same opening 117 is used to receive the baby food concentrate in the first container 9 and to remove the baby food concentrate from the first container 9. In this case the opening corresponds to the outlet opening 117, so that the first container 9 does not have a separately designed inlet or inlet opening. The baby food concentrate is first received through the outlet 113 or the outlet opening 117 into the first container 9, and the outlet 113 is then connected to the dosing device 29. In particular, after the baby food concentrate has been taken up, the outlet 117 can be connected to the inlet 63 of the dosing device 29 by means of a connecting element 149, for example an adhesive element in the form of an adhesive strip 151 or a clip 153.

[0619] With reference to FIGS. 15A to 24, the second receiving area 7 of the device 1, the second container 9, and the dosing device 29 will be described in more detail.

[0620] As FIG. 15A shows, the second receiving area 7 has a rear wall 157, two spaced-apart side walls 159 which are oriented transversely to the rear wall 157, a lower limitation 161 which is oriented transversely to the side walls 159, and one opposite to the lower limitation 161 open top 163. The second receiving area 7 for receiving the second container 11 is formed between the side walls 159. Adjoining or near to the side walls 159 are arranged a multiplicity of clamping elements 155 which extend at least partially between a front side 159 opposite the rear wall 157 and the rear wall 165 of the second receiving area 7.

[0621] The embodiment of the second receiving area 7 illustrated in FIGS. 15A to 15C comprises three pairs of clamping elements 167, 169, 171 which are arranged adjoining or near to the side walls 159. Each of the clamping element pairs 167, 169, 171 is arranged in a plane which is arranged essentially parallel to the lower limitation 161 of the second receiving area 7. The clamping elements 155 can be designed as clamps, two of the clamps being arranged opposite each other and in the plane parallel to the lower limitation 161 of the second receiving area 7. It is conceivable that one of the clamping elements of the first, lower clamping element pair 167 is replaced by the tempering device (not shown). Thus, the second container 11 can be closed or clamped by the interaction of a clamping element with the tempering device, the temperature of the fluid inside the second container 11 being able to be controlled at the same time.

[0622] A first of the clamping element pairs 167, 169, 171 is arranged as a lower clamping element pair 167 in such a way that the clamping elements of the first, lower clamping element pair 167 have a first distance D1 from the lower limitation 161. A second of the clamping element pairs 167, 169, 171 is arranged as the upper clamping element pair 169 in such a way that the clamping elements of the second, upper clamping element pair 169 have a second distance D2 to the lower limitation 161, which is greater than the first distance D1 to the lower limitation 161. The first, lower pair of clamping elements 167 can be arranged adjoining or near to the lower limitation 161 in the second receiving area 7. The second, upper pair of clamping elements 169 is arranged adjoining or near to the open upper side 163. Furthermore, a third of the clamping element pairs 167, 169, 171 can be arranged as a middle clamping element pair 171 between the first clamping element pair 167 and the second clamping element pair 169 and have a third distance D3 to the lower limitation 161, which is greater than the first distance D1 and less than the second distance D2.

[0623] The distance or distance of the clamping elements 155 relative to the lower limitation 161 or relative to the open upper side 163 can be changed. In particular, the third, middle pair of clamping elements 171 is height-adjustable in that the third distance D3 can be changed. This enables the exact dosage of the desired amount of fluid (in particular amount of liquid) for the preparation of baby food. The first, lower clamping element pair 167 and the second, upper clamping element pair 169 can, however, also be adjustable in height, so that the first distance D1 and the second distance D2 can be changed.

[0624] The second container 11 can, as shown in FIGS. 15A and 15B, be inserted into the second receiving area 7 and, as shown in FIG. 15C, can be received by the second receiving area 7. 15C shows the state of the second container 11 received in the second receiving region 7. The second container 11 is introduced into the second receiving area 7 by a movement that is essentially perpendicular to the lower limitation 161.

[0625] In the state received in the second receiving area 7, the second container 11 is held or clamped laterally by three pairs of clamping elements 167, 169, 171. The three pairs of clamping elements 167, 169, 171 can assume a first position (see FIG. 15C) and a second position (not shown). In the first position, the three pairs of clamping elements 167, 169, 171 laterally adjoin the second container 11 and/or touch the second container 11 in such a way that the pairs of clamping elements 167, 169, 171 exert pressure on opposing first and second side walls 173, 175 of the second container 11 exercise. In the second position, the three pairs of clamping elements 167, 169, 171 do not adjoin the second container 11 or they do not touch the second container 11, so that the pairs of clamping elements 167, 169, 171 do not exert any pressure on the side walls 173, 175 of the second container 11.

[0626] FIG. 16 shows an embodiment of one of the three pairs of clamping elements 167, 169, 171 and the arrangement of a first clamping element 177 and a second clamping element 179 of one of the clamping element pairs 167, 169, 171 relative to each other. In the position in which the first clamping element 177 and the second clamping element 179 are arranged relative to each other, the individual clamping elements of the three clamping element pairs 167, 169, 171 in the second receiving region 7 are also arranged relative to each other.

[0627] Each of the clamping elements 155,177,179 comprises a first clamping element surface 181 and a second clamping element surface 183, the clamping element surfaces 181, 183 being arranged on opposite sides of a clamping element longitudinal axis 185, the two clamping element surfaces 181, 183 preferably being connected by means of a third clamping element surface 186, and the third clamping element surface 186 has a essentially conically shaped cross section transverse to the clamping element longitudinal axis 185.

[0628] The first and second clamping element surfaces 181, 183 are arranged essentially parallel to each other and each extend in the direction of the clamping element longitudinal axis 185 between a first end 187 and a second end 189. The first clamping element surface 181 extends in a first plane and the second clamping element surface 183 extends in a second plane, wherein the first plane and the second plane are aligned parallel to each other and/or wherein the clamping element longitudinal axis 185 is in a plane between the first and second level is arranged. The width B of the two clamping element surfaces 181, 183, i.e. the width B of the two clamping element surfaces 181, 183 at an angle different from 0° or 180°, in particular transverse to the clamping element longitudinal axis 185, tapers from the first end 187 to the second end 189. Furthermore, each of the clamping elements 177, 179 comprises a connecting plate 191 which is arranged at an angle different from 0° or 180°, in particular transversely to the clamping element longitudinal axis 185. The first clamping element surface 181 is connected with the first end 187 to the connection plate 191 and the second clamping element surface 183 can be connected with the first end 187 to the connection plate 191.

[0629] With the connecting plate 191, the individual clamping elements 155, 177, 179 can be connected to the second receiving area 7, in particular to the rear wall 157 of the second receiving area 7, so that the clamping elements 155, 179, 179 are essentially transverse to the rear wall 157 in one of 0° or 180°, in particular transversely, so that the second end 189 of the individual clamping element surfaces 181, 183 are spaced from the rear wall 157 and the clamping elements 155, 177, 179 are adjoining or near to the side walls 173, 175 between the front side 165 and the rear wall 157 extend.

[0630] The third clamping element surface 186 extends from a first side edge 193 of the first clamping element surface 181 to a first side edge 195 of the second clamping element surface 183. The first side edges 193, 195 extend in the same plane, which extends at an angle different from 0° or 180°, preferably at an angle of 90°, in particular transversely to the longitudinal axis 185 of the clamping element. The third clamping element surface 186 is arranged at an angle of 90° to the first clamping element surface 181 and to the second clamping element surface 183 and in each case at an angle of 90° to the connecting plate 191 and to the rear wall 157 of the second receiving area 7 when the connecting plate 191 is connected to the rear wall 157 is. Each of the clamping elements 155, 177, 179 of the individual clamping element pairs 167, 169, 171 can thus have a third clamping element surface 186, the third clamping element surfaces 181 of the individual clamping elements 155, 177, 179 of each clamping element pair 167, 169, 171 being aligned parallel to each other when the clamping elements 155, 177, 179 are connected to the rear wall 157 by means of the connecting plate 191. The connecting plate 191 has at least one through hole 192, so that the clamping elements 155, 177, 179 can be connected to the rear wall 157 by means of a connecting element, for example a screw. However, it is also conceivable that the clamping elements 155, 177, 179 are not connected to the rear wall 157 by means of a connecting plate 191, but that the clamping elements 155, 177, 179 are displaceable on the rear wall by means of a slide or by means of a rail or guide rail element 157 and/or are arranged or connectable on the side walls 159 of the second receiving area 7.

[0631] The third clamping element surface 186 can have a clamping element edge 197 which extends essentially in the direction of the clamping element longitudinal axis 185 and between the first side edge 193 of the first clamping element surface 181 and the first side edge 195 of the second clamping element surface 183. The clamping element edge 197 extends in the same plane as the clamping element longitudinal axis 185.

[0632] The clamping elements 155, 177, 179 are designed to be open opposite the third clamping element surface 186 and viewed transversely to the clamping element longitudinal axis 185. In other words, each of the clamping elements 155, 177, 179 comprises an inner cavity 199 which is limited by the three clamping element surfaces 181, 183, 186 and has an open side 201. However, it is also conceivable that the clamping elements 155, 177, 179 are designed without an inner cavity 199. When the clamping elements 155, 177, 179 are connected to the second receiving area 7, for example when the clamping elements 155, 177, 179 are connected to the rear wall 157 by means of the connecting plate 191 or when the clamping elements 155, 177, 179 are connected by means of a slide or rail or guide rail element are connected to the rear wall 157 and/or the side walls 159, the open side 201 of the inner cavity 199 points to one of the two side walls 159 of the second receiving area 7. At least one of the clamping element surfaces 181, 183, 186, preferably the third clamping element surface 186, can be designed as a support surface, preferably a rubberized support surface. Preferably, each of the clamping elements 155, 177, 179 comprises a spring element (not shown). The spring element can be arranged adjoining or near to the first end 187 of the first clamping element surface 181 or the second clamping element surface 183. The clamping elements 155, 177, 179 can be formed from an elastomer or comprise an elastomer in order to generate a uniform surface pressure when the second container 11 is held or clamped by the clamping elements 155, 177, 179.

[0633] The tempering device can be arranged in contact with the second container 11, the tempering device preferably being arranged in an area adjoining or near to the lower limitation 161 of the second receiving area 7 and/or wherein the tempering device is arranged in an area adjoining or near to one of the clamping elements 155, 177, 179 which is closest to the lower limitation 161 is arranged. The tempering device is therefore preferably arranged or in contact at the lowest point of the second container 11 (in the state inserted into the second receiving area 7). This ensures uniform heating and/or mixing of the fluid inside the second container 11,

[0634] The tempering device can be arranged adjoined to or near to the first, lower pair of clamping elements 167. When the second container 11 is received by the second receiving area 7, a lower area of the second container 11 is arranged adjoining, preferably adjacent, to the tempering device so that the fluid (especially the liquid) inside the second container 11 can be temperature controlled.

[0635] FIGS. 17A and B show a possible embodiment of the second container 11 for receiving and dosing fluid for the preparation of baby food, which is designed to be introduced and received in a device 1 for the preparation of baby food. The second container 11 comprises a housing 203 with an interior space 205 for receiving fluid, an inlet 207 in fluid connection with the interior space 205 and an outlet 209 in fluid connection with the interior space 205. The housing 203 can be formed from a flexible material, for example from a film material. Furthermore, the inlet 207 of the second container 11 can be connected to an outlet 211 or to an outlet opening 255 of a fluid reservoir 213, such that a dosing of the fluid for the preparation of baby food can be delivered through the outlet 209 of the second container 11.

[0636] The inlet 207 of the second container 11 comprises an inlet opening 215, which is preferably essentially opposite to the outlet 209 of the second container 11 in the direction of a container longitudinal axis 217 and/or essentially opposite to an outlet opening 219 of the outlet 209 of the second container 11 in the direction of container longitudinal axis 217 is arranged seen. The second container 11 thus comprises an inlet 207 with an inlet opening 215 and an outlet 209 with an outlet opening 219, the outlet 209 being arranged on a side opposite to the inlet 207.

[0637] When the second container 11 is introduced into the second receiving area 7 by an essentially vertical movement through the open top 163, the second container 11 is received by the second receiving area 7 such that the outlet 209 is in a lower area 221 of the second receiving area 7 is arranged, adjoining or near to the first, lower clamping element pair 167 and adjoining or near to the lower limitation 161. For example, the outlet 209 of the second container 11 can be passed through the through-hole 223 in the lower limitation 161 of the second receiving area 7, preferably by a essentially perpendicular movement to the lower limitation 161 (see FIG. 18). At the same time, the inlet 207 of the second container 11 is arranged in an upper area 225 of the second receiving area 7, adjoining or near to the open top 163 and adjoining or near to the second, upper pair of clamping elements 169.

[0638] The outlet 209 of the container 11 is designed for insertion into the through-hole 223 in the lower limitation 161 of the second receiving area 7.

[0639] The outlet 209 of the second container 11 can be configured as an elongated element, for example the outlet 209 can be tubular and extend between a first end 227 and an opposite second end 229 along a longitudinal outlet axis 231. The outlet 209 comprises one outside diameter that is smaller than the inside diameter of through-hole 223 in the lower limitation 161 of the second recording area 7. Hence, the outlet 209 of the second container 11 can through the through-hole 223 in the lower limitation 161 of the second receiving area 7 are passed through when the second container 11 is inserted into the second receiving area 7. The second end 229 of the outlet 209, when the second container 11 is received in the second receiving area 7, can lie in a plane which is below the plane of the lower limitation 161.

[0640] The second container 11 extends between an inlet end 233 and an opposite outlet end 235 along the longitudinal axis 217 of the container. Adjoining or near to the inlet end 233, the inlet opening 215 and the inlet 207 are arranged. The outlet 209 and the outlet opening 219 are arranged adjoined or near to the outlet end 235. The outlet longitudinal axis 231 can run in the same plane as the container longitudinal axis 217, which essentially corresponds to a central longitudinal axis of the second container 11. However, it is also conceivable that the outlet longitudinal axis 231 runs in a plane parallel to the container longitudinal axis 217.

[0641] The second container 11 has a first side wall 173 and an opposing second side wall 175 which extend essentially parallel to the plane of the container longitudinal axis 217 between the inlet end 233 and the outlet end 235. The second container 11 has at least partially a tapering section 241 in the lower region near to the outlet end 235, the periphery of the second container 11 decreasing, preferably essentially conically, in the tapering section 241 towards the outlet 209. In the tapering section 241, the distance between the first side wall 173 and the second side wall 175 decreases towards the outlet 209, preferably essentially conically. This enables the fluid (in particular the liquid) to be guided almost completely out of the second container 11 through the outlet 209.

[0642] The second container 11 has at least partially a essentially symmetrical section 243, wherein the periphery of the second container 11 remains the same within the essentially symmetrical section 243 and wherein the essentially symmetrical section 243 is further spaced from the outlet 209 of the second container 209 than the tapered portion 241.

[0643] In the essentially symmetrical section 243, the first side wall 173 and the second side wall 175 each extend in a plane parallel to the plane of the longitudinal axis 217 of the container. The essentially symmetrical section 243 extends between the inlet end 233 and the tapered section 241. When the second container 11 is inserted or received in the second receiving area, the clamping elements 155 of the individual clamping element pairs 167, 169, 171 adjoin the side walls 173, 175 in the essentially symmetrical section 243 and exert pressure on the side walls 173, 175.

[0644] Preferably, the distance between the two side walls 173, 175 in the essentially symmetrical section 243 is between approximately 20 mm to 60 mm (for example approximately 30 mm) and/or the length of the two side walls 173, 175 175 in the essentially symmetrical section 243 is in the range of approximately 150 mm to 300 mm (e.g. approximately 220 mm).

[0645] The distance between the two side walls 173, 175 decreases in the tapering section 241 from approximately 20 mm to 60 mm (e.g. approximately 30 mm) towards the second end 229 of the outlet 209 to approximately 10 mm to 50 mm (e.g. approximately 20 mm). Preferably, the distance between the two side walls 173, 175 in the outlet (209) is approximately 10 mm to 50 mm (e.g. approximately 20 mm).

[0646] As FIGS. 19 and 20 show, the inlet 207 of the second container 11 can be connected to an outlet 227 of the fluid reservoir 213, so that fluid (in particular liquid) can be dosed from the fluid reservoir 213 into the interior of the second container 111 and by means of the clamping elements 155 of individual pairs of clamping elements 167, 169, 171, the fluid can be dosed in the desired amount that is necessary for the preparation of baby food and guided out of the second container 11 through the outlet 209. The inlet 207 of the second container 11 can be firmly connected to the outlet 255 of the fluid reservoir 213, for example screwed or glued. The fluid reservoir 213 can, however, also be integrated into the second container 11.

[0647] The second container 11 can have a essentially horizontal plate 245 which is arranged adjoining or near to the inlet opening 215 and/or adjoining or near to the inlet 207 of the second container 11. The plate 245 is particularly advantageous when the fluid reservoir 213 is not designed as a dimensionally stable container or when it is not a combination container 284, as described later with reference to FIGS. 25A, 25B and 26. The plate 245 can preferably be connected to the second container 11 or the plate 245 is firmly connected to the second container 11 or the plate 245 is integrated into the second container 11. The plate 245 or suspension tab can be connected to the upper region near to the inlet end 233 of the second container 11 in a fixed or detachable manner. The plate 245 can be formed integrally with the second container 11. The plate 245 preferably has a surface shape that essentially corresponds to the surface shape of a cross section of the second container 11 at an angle different from 0° or 180°, preferably at an angle of 90°, in particular seen transversely to the longitudinal axis 217 of the second container 11, corresponds. The surface shape of the plate 245 is for example rectangular. The distance between two opposite sides of the plate is preferably equal to or greater than the distance between two opposite side surfaces, for example the distance between the first side wall 173 and the second side wall 175 of the second container 11 when the second container 11 is inserted into the second receiving area 7 and is assumed or if it is filled with a fluid or if a fluid is received in the interior space 205 of the second container 11. As FIGS. 19 and 20 show, when the second container 11 is accommodated in the second receiving area 7, the plate 245 rests on the edges or peripheral surfaces of the open top 163, so that the plate 245 at least partially, preferably completely, the open top 163 covers.

[0648] The plate 245 comprises a through hole 247, the through-hole 247 preferably comprising a first flange 249 with a first peripheral wall 251, the first peripheral wall 251 at least partially surrounding the through hole 247 and at an angle different from 0° or 180°, in particular extending essentially transversely from a first side 253 of the plate 245. The first flange 249 is designed to connect the plate 245 to the outlet 211 of the fluid reservoir 213 and/or to an outlet opening 255 of the fluid reservoir 213.

[0649] FIGS. 19 and 20 show an embodiment in which the first flange 249 can be connected to the outlet 211 of the fluid reservoir 213, for example by a plug connection. The fluid reservoir 213 is designed as a tank. Accordingly, the outer diameter of the first flange 249 or the first peripheral wall 251 is slightly smaller than the inner diameter of the outlet 211 of the fluid reservoir 213. Thus, the outlet 211 of the fluid reservoir 213 can be plugged onto the first flange 249 in a simple manner and thus connected to the first flange 249, so that the fluid can be reliably introduced into the second container 11.

[0650] FIG. 21 shows an exemplary embodiment in which the first flange 249 can be connected to the outlet 211 of the fluid reservoir 213 by a screw connection. The fluid reservoir 213 is a bottle in which fluid suitable for the preparation of baby food is received and which can be purchased, for example, in the supermarket. The first peripheral wall 251 of the first flange 249 comprises a first thread 257, the first thread 257 being arranged on the inside of the first peripheral wall 251, which faces the through-hole 247 in the plate 245. The first thread 257 is designed to be screwed to a second thread 259 on the outside of a peripheral wall 261 of the outlet 211 of the fluid reservoir 213.

[0651] The plate 245 can be connectable to the second container 11 or can be firmly connected to the second container 11 or integrated into the second container 11. In particular, the plate 245 can be firmly connected or integrated with the second container 11 with a second side 262, which is arranged opposite to the first side 253, the through-hole 247 of the plate 245 being fluidically connected to the inlet 207 of the second container 11.

[0652] As shown in FIG. 21 shows, the through-hole 247 can have a second flange 263 with a second peripheral wall 265, the second peripheral wall 265 at least partially surrounding the through-bore 247 and extending essentially transversely away from the second side 262 of the plate 245. The second flange 263 is designed to connect the plate 245 to the inlet 207 and/or to the inlet opening 215 of the container 11.

[0653] The second flange 263 and the second peripheral wall 265 are arranged on the second side 262 of the plate 245 such that the second flange 263 and the second peripheral wall 265 at least partially surround the through-hole 247 of the plate 245. The second flange 263 and the second peripheral wall 265 are configured essentially like the first flange 249 and the first peripheral wall 251. The first flange 249 and the second flange 263 surround the same flange center longitudinal axis 267, which extends at an angle different from 0° or 180°, in particular transversely to the plane of the plate 245 and/or through the through opening 247 of the plate 245. Thus, the plate 245 can be connected to the fluid reservoir 213 by means of the first flange 249 and to the inlet 207 of the second container 11 by means of the second flange 263, a fluid reservoir center longitudinal axis 269 of the fluid reservoir 213 and the container longitudinal axis 217 of the second container 11 are in the same straight line with the flange central longitudinal axis 267 in fig when the fluid reservoir 213, the plate 245, and the second container 11 are connected to each other.

[0654] FIG. 22 shows an embodiment in which the inlet 207 of the second container 11 can be connected directly to the outlet 211 of the fluid reservoir 213. The fluid reservoir 213 is designed in such a way that a plate 245 can be dispensed with. The outlet 211 of the fluid reservoir 213 can be connected to the inlet 207 of the second container 11 by means of a plug connection or by means of a screw connection as previously described; in the exemplary embodiment in FIG. 22, the inlet 207 of the second container 11 has the first thread 257 on the inside of the inlet 207, which points towards the inlet opening 215, and can be screwed to the second thread 259 on the outside of the outlet 211 relative to the outlet opening 255 of the fluid reservoir 213. The fluid reservoir 213 comprises a housing 271 with an upper side 273 and a lower side 275, the upper side 273 and the lower side 275 being arranged at opposite ends to the fluid reservoir central longitudinal axis 269. The outlet 211 of the fluid reservoir 213 comprises on the underside 275, the underside 275 running in a essentially horizontal plane or in a plane at an angle different from 0° or 180°, in particular at an angle of 90°, transversely to Fluid reservoir central longitudinal axis 269 seen. The design of the lower side 275 assumes the function of the plate 245.

[0655] As FIGS. 23A and 23B show, the second container 11 comprises at least one first magnet 277, wherein the at least one first magnet 277 is preferably arranged on an outer wall 279 of the tapering section 241 of the second container 11, and wherein the at least one first magnet 277 can be connected to at least one second magnet 281 adjoining or near to the through-hole 223 in the lower limitation 161 of the second receiving area 7. The at least one second magnet 281 is arranged on an inner wall 283 of the through-hole 223. The at least one first magnet 277 may include a first magnetic plate and a second magnetic plate, which on opposite sides are arranged at an angle different from 0° or 180°, in particular transversely to the longitudinal axis 217 of the container. The at least one second magnet 281 can have a first magnetic contact and a second magnetic contact, which are arranged on opposite sides of the through hole 223 on its inner wall. As FIG. 24 shows, the second container 11 can be correctly received or placed in the second receiving area 7 by the magnets 277, 281, so that the fluid for preparing baby food can be guided out of the outlet 209 of the second container 11 without fluid reaches the housing of the second receiving area 7. As an alternative to the first magnet 277 or the second magnet 281, a metal element (or a metal plate or a metal strip) can also be provided.

[0656] FIGS. 25A and 25B show a combination container 284 in which the second container 11 and the fluid reservoir 213 are connected to each other. The second container 11 and the fluid reservoir 213 can be connected to each other in one piece as a unit, the fluid reservoir 213 and/or the second container 11 being filled with fluid. It is also conceivable here that only the fluid reservoir 213 is filled with fluid and the second container 11 or the dosing and sterilization area is fastened to the fluid reservoir 213 in a folded-in manner. The fluid reservoir filled with fluid, for example a Tetra-Pak, can be separated from the second container 11 or from the dosing and sterilization bag with a clip or with an adhesive strip

[0657] However, it is also conceivable that the second container 11 and the fluid reservoir 213 are first produced separately from each other and then connected to each other as previously described, for example by gluing, and are filled with fluid. The combination container 284 can also comprise a positioning and holding device 285, which are provided as an alternative to the connecting plate 191 described above and which serve a essentially similar purpose. The positioning and holding device 285 is preferably designed as a clamp or as a C-clamp or as a C-holding element with a C-shape. This C-clamp is arranged between the second container 11 and the fluid reservoir 213, preferably at the point at which the second container 11 is connected to the fluid reservoir 213. The C-clamp or the C-holding element can for example be attached, preferably glued, to the underside of the fluid reservoir 213 or to the upper side of the second container 11.

[0658] As FIG. 26 shows, the combination container 284 can be positioned and held by means of the positioning and holding device 285 on one of the side walls 159 of the second receiving area 7, preferably in an upper area of the second receiving area 7. However, it is also conceivable that a cover with an opening is provided (not shown), by means of which the open top 163 of the second receiving area 7 can be closed or covered so that the combination container 284 is positioned on the cover by means of the positioning and holding device 285 and can be held. The positioning and holding device 285 can be arranged around the opening on the cover in such a way that the positioning and holding device 285 surrounds the opening and the second bag 11 is arranged below the cover and the fluid reservoir 213 is arranged above the cover when the combination container 284 is inserted into the second receiving area 7. The positioning and holding device 285 prevents the combination container 284, in the state inserted into the second receiving area 7, from sliding downwards in the direction of the lower limitation 161 while the fluid is being emptied. This ensures that the second container 11 can be completely emptied.

[0659] The system, as previously described, comprises a device 1 for preparing baby food, in particular baby milk or baby mash, a first container 9 for receiving and dosing baby food concentrate and a second container 11 for receiving and dosing fluid (in particular liquid), so that by means of this system the baby food can be prepared. For this purpose, the first container 9 is designed for receiving and dosing baby food concentrate and for receiving and interacting with the device 1 for preparing baby food. The second container 11 is designed for receiving and dosing fluid and for receiving and interacting with the device 1. The device 1 comprises the first receiving area 5, which is designed to receive the first container 9 and to receive and drive the dosing device 29 that can be connected to the container 9. Since the dosing device 29 is driven by the actuation and/or drive device 39, which is arranged in the dosing device receiving area 27 within the first receiving area 5, the baby food concentrate and/or the fluid can be correctly dosed. The device 1 also comprises the second receiving area 7, which is designed to receive the second container 11. The fluid can be correctly dosed by means of the clamping elements 155 which are arranged in the second receiving area 7. With the device 1, the baby food concentrate from the first container 9 and the fluid from the second container 11 can be conveyed to a preparation device and introduced into a container, in particular a baby bottle, in the correct mixing ratio. The device 1 thus enables a simplified, correct and safe preparation of baby food.

[0660] An exemplary embodiment of a device 1′ for dosing and grinding coffee powder and/or for preparing coffee is described with reference to FIGS. 27 to 29. In the following, the device 1′ for dosing and grinding coffee powder and/or for preparing coffee is explained solely on the basis of the features that differ from the device 1 as previously described. It is therefore conceivable that the device 1′ described below can also be used for the dosing and preparation of baby food if a first container 9 with baby food concentrate is inserted into the first receiving area 5′ of the device 1′ instead of the first container 9′ with coffee beans is used.

[0661] The device 1′ for dosing and grinding coffee powder and/or for preparing coffee differs from the device 1 previously described in FIGS. 1 to 26 in that the dosing device 29 is used as a dosing and grinding device 29′ for dosing and grinding coffee beans is configured, wherein the first receiving area 5′ has a dosing and grinding device receiving area 27′ for receiving the dosing and grinding device 29′, and in the dosing and grinding device receiving area 27′ an actuating and/or drive device 39 for the dosing and Grinding device 29′ is arranged.

[0662] FIG. 27 shows the device 1′, a first container 9′ for coffee beans and the dosing and grinding device 29′ connected to it being inserted into the first receiving area 5′ of the device 1′. Furthermore, the second container 11 is inserted into the second receiving area 1′ of the device 1′.

[0663] FIGS. 28 and 29 show the dosing and grinding device 29′. The dosing and grinding device 29′ comprise a screw conveyor 57′, a grinder 287 and a screw conveyor housing 59. The grinder 287 is preferably inserted in its full length into the screw conveyor housing 59 and is rotatably arranged therein and the screw conveyor 57′ is preferably inserted in its full length into the screw conveyor housing 59 and is rotatably arranged therein. When inserted into the screw conveyor housing 59, the grinding mechanism 287 and the screw conveyor 57′ extend near to each other along the longitudinal axis of the screw conveyor housing 59, which runs in one plane or in a straight line with the screw conveyor screw axis 61, so that the grinding mechanism 287 and the screw conveyor 57′ can be operated and/or driven simultaneously by the operating and/or drive device 39. As a result of the actuation and/or drive, the conveyor screw 57′ transports the coffee beans introduced through the inlet 53 from the first container 9′ in the direction of the conveyor screw longitudinal axis 61 to the grinder 287, so that the coffee beans are ground to coffee powder by the grinder 287 and so that the ground Coffee powder leaves the screw conveyor housing 59 through the outlet 67. The screw conveyor 57′ of the device 1′ is designed essentially like the screw conveyor 57 of the device 1, the length of the screw conveyor 57′, 57 differing. In other words, the screw conveyor 57′ is shorter than the screw conveyor 57, so that the length of the screw conveyor 57′ between the opposite ends in the direction of the conveyor screw longitudinal axis 61 is shorter than in the screw conveyor 57.

[0664] The screw conveyor housing 59 extends between a first end 71 and an opposite second end 73 along the longitudinal axis of the screw conveyor housing 59, the grinder 287 being arranged adjoining to or near to the first end 71 and extending along the longitudinal axis 297 of the grinder and the longitudinal axis of the screw conveyor housing 59, wherein the screw conveyor 57′ is arranged adjoining or near to the second end 73 and extends along the longitudinal axis 61 of the screw conveyor, with the outlet 67 being arranged adjoining or near to the first end 71 and the inlet 53 of the screw conveyor housing 59 adjoining or near to the second end 73 is arranged. The inlet 53 is arranged above the screw conveyor 57′. The coffee beans can thus enter the screw conveyor housing 59 from the second container 11 solely by the action of gravity and then be conveyed by the screw conveyor 57′ in the direction of the grinder 287. The outlet 67 of the screw conveyor housing 59 is arranged below the grinder 287. The coffee powder ground by the grinder 287 can leave the screw conveyor housing 59 or the screw conveyor and grinder housing 59 through the outlet 67 solely by the action of gravity and be brought into connection with the fluid for preparing coffee.

[0665] The grinding mechanism 287 has a first end 301 and an opposite second end 303 along a grinding mechanism longitudinal axis 297. The first end 301 of the grinder 287 is designed as a drive end 289 of the grinder 287. The screw conveyor 57′ has a first end and an opposite second end along the longitudinal axis 61 of the screw conveyor. The first end of the screw conveyor 57′ is designed as a drive end 82 of the screw conveyor 57′

[0666] A coupling device 91 extends from the drive end 82 of the screw conveyor 57′ in the direction of the longitudinal axis 61 of the screw conveyor 57′, and a coupling device 291 extends from the drive end 289 of the grinding mechanism 287 along the longitudinal axis 297 of the grinding mechanism. The coupling device 91 of the screw conveyor 57′ is designed to interact in a coupling manner, in particular to intervene, with an actuating and/or drive device 293 of the grinding mechanism 287, which is arranged at the second end of the grinding mechanism 287. The coupling device 91 of the grinder 287 is designed to interact in a coupling manner with the actuating and/or drive device 39 for the dosing and grinding device 29′, in particular to intervene.

[0667] In the interconnected state, the coupling device 91 of the screw conveyor 57′ engages with the actuating and/or drive device 293 of the grinder 287 such that the grinder longitudinal axis 297 and the conveyor screw longitudinal axis 61 run in one plane or in a straight line, and in the screw conveyor housing 59 inserted state with the longitudinal axis of the screw conveyor housing 59 extend in one plane or in a straight line. Thus, by actuating or driving the actuating and/or drive device 39 of the device 1′, the grinder 287 and the screw conveyor 57′ can be driven simultaneously via the same shaft.

[0668] The coupling device 91 of the screw conveyor 57′ is designed as an essentially cylindrical cavity and/or as a receptacle which extends essentially in the direction of the longitudinal axis 61 of the screw conveyor. Correspondingly, the coupling device 291 of the grinding mechanism 287 is designed as an essentially cylindrical cavity and/or as a receptacle which extends essentially in the direction of the grinding mechanism longitudinal axis 297.

[0669] The grinding mechanism 287 has a grinding mechanism core 299 with an essentially conically shaped longitudinal section in the direction of the grinding mechanism longitudinal axis 297. The grinder core 299 extends between the first end 301 and the second end 303 of the grinder 287 in the direction of the grinder longitudinal axis 297. Corresponding to the conically shaped longitudinal section of the grinding mechanism core 299, the periphery of the grinding mechanism core 299, seen transversely to the grinding mechanism longitudinal axis 297, decreases from the first end 301 in the direction of the second end 303.

[0670] The grinder 287 has an inner ring 305 adjoining or near to the second end 303. The inner ring 305 extends at least partially around the grinder core 299 from the second end 303 in the direction of the first end 301. The inner ring 305 surrounds the longitudinal axis 297 of the grinder and preferably has a essentially conical longitudinal section along the longitudinal axis 297 of the grinder, the cross-sectional area of the inner ring 305 tapering towards the second end 303.

[0671] The inner ring 305 of the grinder 287 seated on the grinder core 299 or on the shaft can be moved by means of an adjusting element 307 along the grinder longitudinal axis 297, in the direction of the first end 301 and/or in the direction of the second end 303 of the grinder 287. The adjusting element 307 is arranged adjoining or near to the first end 301 and surrounds the longitudinal axis 297 of the grinding machine concentrically. By means of the adjusting element 307, the inner ring 305 can be displaceable in the direction of the first end 301 and/or in the direction of the second end 303 of the grinder 287. This enables a degree of grinding to be set in a simple manner.

[0672] The grinder 287 can have a spring element (not shown) which is arranged adjoining or near to the inner ring 305 and/or adjoining or near to the second end 303 of the grinder 287 or the grinder core 299. The spring element can be arranged in a recess 309 within the grinder core 299, the recess 309 extending at least partially in the direction of the grinder longitudinal axis 297 and or parallel to the grinder longitudinal axis 297 and in the direction of the first end 301.

[0673] The grinder 287 has an outer ring 311. This outer ring 311 has a essentially cylindrical cross section and an inner periphery that is larger than the outer periphery of the inner ring 305. The outer ring 311 is arranged on the inner wall 313 of the screw conveyor housing 59 and is arranged on the inner wall 313 of the screw conveyor housing 59 by means of a holding element 315, for example a hold-down 315. The hold-down device 315 extends between the first open end 71 of the screw conveyor housing 59, adjoining or near to the adjusting element 307, as far as the outer ring 311 along the inner wall 313 of the screw conveyor housing 59. Outer ring 311 can be held in a fixed or stationary position by holding-down device 315.

[0674] The hold-down device 315 does not have to adjoin the outer ring 311 at every point on the circumference of the outer ring 311 so that the outer ring 311 is held in a fixed or stationary position. This is not necessary because of the rigidity of the outer ring, which is preferably made of ceramic material or which preferably comprises ceramic material. It is sufficient that the holding-down device 315 is in contact with the outer ring 311 at least two points or contact points, preferably three points or contact points, so that the outer ring 311 can be held in a fixed or stationary position. The three points can preferably be arranged at 120° intervals around the longitudinal axis of the grinder. This enables the hold-down 315 not to block the outlet 67 or the outlet opening 69 of the screw conveyor housing 59, so that the ground coffee powder can exit from the screw conveyor housing 59.

[0675] The outer ring 311 is arranged around the inner ring 305 so that the inner ring 305 can rotate within the outer ring 311 due to the drive of the grinding mechanism 287. By adjusting the degree of grinding by means of the adjusting element 307, the position of the inner ring 305 relative to the outer ring 311 (viewed in the direction of the longitudinal axis 61 of the conveyor screw) can be adjustable, so that an intermediate space 317 between the inner ring 305 and the outer ring 311 can be adjusted. Within the intermediate space 317, the coffee beans can be ground to coffee powder at the interfaces of the inner ring 305 and the outer ring 311. The coffee beans conveyed by the screw conveyor 57′ in the direction of the grinder 287 thus reach the space 317 between the inner ring 305 and the outer ring 311 and can be ground into coffee powder due to the rotation of the inner ring 305 within the outer ring 311. The inner ring 305 and the outer ring 311 are adjoining or near to the outlet 67 or to the outlet opening 69 of the screw conveyor housing 59 is arranged. Thus, the coffee powder ground between the inner ring 305 and the outer ring 311 can exit the screw conveyor housing 59 through the outlet 67.

[0676] As FIG. 27 shows, the second receiving area 7′ has a rear wall 157, two spaced apart side walls 159 which are oriented at an angle different from 0° or 180°, in particular essentially transversely to the rear wall 157, a lower limitation 161 which is oriented at an angle different from 0° or 180°, in particular transversely to the side walls 159, 159′, and an open top 163 opposite the lower limitation 161, at least one of the side walls 159′ being an inclined side wall 159′ which is oriented at an angle different from 90°, preferably at an angle between 10° and 50°, more preferably at an angle between 10° and 30°, particularly preferably at an angle of 20°, to the lower limitation 161.

[0677] The inclined side wall 159′ is connected or connectable to the rear wall 157 and is spaced apart from the lower limitation 161. The lower edge 319 of the inclined side wall 159′ or the edge 319 of the inclined side wall 159′, which points to the lower limitation 161 of the second receiving area 7, can be adjoining or near to a flange 321 which surrounds the through-hole 223 in the lower limitation 161 can be arranged. The inclined side wall 159′ is designed to receive the second container 11 with fluid and to hold it in the inclined position, so that the second container 11 rests or is supported with one of its outer side walls on the inclined side wall 159′. The second container 11 can be held in an inclined position by the inclined side wall 159′, so that the outlet 209 of the second container 11 can open into the through-hole 223 which is surrounded by the flange 321.

[0678] The first container 9 with the dosing and grinding device 29 is arranged in a position that is essentially transverse, preferably at an angle of 90° to the lower limitation 161 and above the lower limitation 21 of the first receiving area 5′ and/or above the lower limitation 161 of the second receiving area 7′ and/or arranged above the through-hole 223. Thus, the outlet 67 from the screw conveyor housing 59 and the outlet 209 of the second container 11 can advantageously open together into the through-bore 223. This enables the ground coffee powder and the fluid to be guided through the through-hole 223 in the device 1″ for dosing and grinding coffee powder and/or for preparing coffee, so that the coffee powder and the fluid can be fed to a container, preferably a filter container. However, it is also conceivable that the outlet 67 from the screw conveyor housing 59 and the outlet 209 of the second container each open through spaced through bores 51, 223, as shown in the first exemplary embodiment of the device 1 (see FIGS. 4 and 18).

[0679] Adjoining or near to the inclined side wall 159′, three clamping elements 155 are arranged, which run in a plane or clamping element plane parallel to the inclined side wall 159′. The clamping element plane is oriented at an angle different from 90°, preferably at an angle between 10° and 50°, more preferably at an angle between 10° and 30°, particularly preferably at an angle of 20°, to the lower limitation 161. The second container 11 is held between the inclined side wall 159′ and the clamping elements 155, so that one of the side walls of the second container 11 rests or rests on the inclined side wall 159′ and an opposite side wall of the second container 11 rests on the clamping elements 155. Thus, the fluid (in particular the liquid) can be dosed out of the second container 11 by means of the clamping elements 155.

[0680] FIG. 30 shows a first embodiment of a preparation device 323, which can preferably be used to prepare a coffee using the cold brew method or type of preparation. The preparation device 323 comprises a filter and/or funnel container 325 or filter container into which the coffee powder and the fluid can be introduced and/or mixed. Furthermore, the preparation device 323 can have a container 327, for example a coffee cup or a coffee pot. The filter and/or funnel container 325 comprises a sieve or a filter 329 which is arranged inside the container 327. A first closing flap 331 for closing a first cavity area 333 and a second closing flap 335 for closing a second cavity area 337 are arranged at the upper open end of the preparation device 323. It is conceivable that the lid can be placed manually on the filter or the jug. Coffee powder, for example, can be introduced into the first cavity area 333 and, for example, fluid can be introduced into the second cavity area 337, in each case from the device 1′ for dosing and grinding coffee beans and/or for preparing coffee. The preparation device 323 further comprises a stirring element or stirrer 339, which is arranged within the container 327 and/or within the sieve or filter 329 when the container 327 is connected to the preparation device 323. It is also conceivable that the preparation device 323 has only one cavity or cavity area and only one closure cap, through which both the coffee or the coffee powder and the fluid are introduced into the filter and/or funnel container 325. It is also conceivable that the mixture is dispensed with so that the device 11 for dosing and grinding coffee beans and/or for preparing coffee only introduces the coffee powder and the fluid in the desired amount into the filter and/or funnel container 325.

[0681] FIG. 31 shows a further embodiment of the preparation device 323′, which can preferably be used to prepare a coffee by means of the dripping method or type of preparation. The preparation device 323′ comprises a container 327′ into which the coffee can be filled. A sieve or a filter 329′ is arranged above the container 327′, which includes the coffee powder and into which cooled water or ice water or fluid mixed with ice cubes is fed from a further container or cooling water container 341. The cooling water tank 341 is preferably arranged above the filter 329′. A valve 343 can be arranged between the cooling water tank 341 and the filter 329′, by means of which the cooling water can be introduced drop by drop into the filter 329′. Instead of the cooling water container 341, the second container 11 with fluid can also be provided, which has cooled fluid in its interior. The second container 11 can for example be cooled by the tempering device so that the fluid can be temperature controlled to the temperature suitable for preparing a coffee by means of the dripping method or type of preparation. As an alternative to temperature control by means of the tempering device, when using a reusable second container 11, ice can be packed or introduced into the interior of the second container.

[0682] To prepare the coffee, the preparation device 323′ is connected to the filter 329′ in such a way that the cooling water or fluid can be fed drop by drop into the filter 329′ and can be mixed with the coffee powder so that finished coffee is placed in the container 327′ can be performed. The preparation device 323′ can further include a stirring element or stirrer 339 which is arranged within the container 327′ and/or within the sieve or filter 329′ when the container 327′ is connected to the preparation device 323′ (not shown). It is also conceivable that the preparation device 323′ has at least one cavity or cavity area and at least one closure cap, preferably two cavity areas and two closure flaps, through which the coffee or coffee powder and the fluid into the sieve or into the filter 329′ are introduced (not shown).

[0683] It is conceivable that instead of the preparation device 323′, 323′, the 3D acoustic waves are used to mix the coffee powder with the fluid. It is also conceivable that the mixture is dispensed with, so that the device 1′ for dosing and grinding coffee beans and/or for preparing coffee only introduces the coffee powder and the fluid in the desired amount into the filter and/or funnel container 325.

[0684] FIGS. 32 to 34 show an embodiment of a first container 9″, in which the grinding device 29″ or the grinding mechanism 287″ is arranged in the outlet 113. By operating the grinder 287″, a defined amount of coffee beans can be ground from the first container 9″ and thus a defined amount of coffee or ground coffee can be dosed at the same time.

[0685] The grinder is introduced into the outlet 113 of the first container 9″ and is rotatably arranged therein so that the grinder 287″ and the outlet 113 extend around a common longitudinal axis or around the longitudinal axis 297 of the grinder. In this way, the coffee beans inside the first container 9″ can be guided gravimetrically towards the outlet 113 and ground.

[0686] The grinder 293″ is operated and/or driven by an actuation and/or drive device 293″. By actuating and/or driving the coffee beans from the first container 9″ can be ground by the grinder 287″ so that the ground coffee powder can leave the container 9″ or the grinder 287″ through the outlet 113 of the first container 9″.

[0687] The grinder 287″ comprises a first end 301 and an opposite second end 303 along the longitudinal axis 297 of the grinder. The first end 301 protrudes from the outlet 113 of the first container 9″ and is therefore arranged outside the first container 9″. The second end 303 is to be arranged inside the first container 9″. Because the first end 301 of the grinder 287″ protrudes from the outlet 113, the first end 301 can be designed as a drive end 301 of the grinder 287″.

[0688] A coupling device 291″ is arranged at the drive end 301 of the grinder 287″. The coupling device comprises a gear transmission with a gear 294, by means of which the grinding device 29″ or the grinder 287″ can be driven.

[0689] The grinding mechanism 287″ comprises a grinding mechanism core 299″ with an essentially conically shaped longitudinal section in the direction of the grinding mechanism longitudinal axis 297. The grinder core 299″ extends between the first end 301 and the second end 303 of the grinder 299″ in the direction of the longitudinal axis 297 of the grinder.

[0690] The grinder 287″ has an inner ring 305″ adjoining or near to the second end 303. The inner ring 305″ extends at least partially around the grinder core 299″ from the second end 303 in the direction of the first end 301.

[0691] The grinder 287″ further comprises an outer ring 311″. The outer ring 311″ adjoins the inner wall of the outlet 113 of the first container 9″ and is arranged around the inner ring 305″ so that the inner ring 305″ can rotate within the outer ring 311″ due to the drive of the grinder 287″. By adjusting the degree of grinding, for example by means of an adjusting element, the position of the inner ring 305″ relative to the outer ring 311″ (viewed in the direction of the longitudinal axis 297 of the grinder) can be adjusted so that a gap between the inner ring 305″ and the outer ring 311″ can be adjusted. Within the space 311″, the coffee beans can be ground to coffee powder at the limitation surfaces of the inner ring 305″ and the outer ring 311″.

[0692] The actuation and/or drive device 293″ comprises a motor 318, the motor 318 being designed to drive the grinder 287″. The motor 318 comprises a gear 293 which is arranged in relation to the gear 294 of the coupling device 291″ so that the gear 293 of the motor 318 comes into contact with the gear 294 of the coupling device 291″ of the grinder 287″ and the grinding device 30 or the grinder 287″ Is driven.

[0693] FIGS. 35 and 36 show a plurality of preparation devices 345 for different types of preparation, for example filter coffee 347, cold brew 349, cold drip 351, espresso 353, and Karlsbader 355. The preparation devices 345 (or preparation units) have at least one ring 357. Some of the rings 357 have at least one notch 359. This enables the device to determine the number of rings 357 and/or the number of notches 359 or the presence of a notch 359 via corresponding sensor elements (not shown) and thus to determine the respective preparation device 345 and then the corresponding type of preparation, e.g. filter coffee, cold brew, cold drip, espresso, Karlsbader, etc., can carry out.

[0694] The system, as previously described, comprises a device 1′ for dosing and grinding coffee beans and/or for preparing coffee, a first container 9′ for receiving and dosing coffee beans and a second container 11 for receiving and dosing fluid (in particular liquid), so that the coffee can be prepared using this system. For this purpose, the first container 9′ is designed to receive and dose coffee and to receive and interact with the device 1′. The second container 11 is designed for receiving and dosing fluid and for receiving and interacting with the device 1′. The device 1′ comprises the first receiving area 5′, which is designed to receive the first container 9′ and to receive and drive the dosing and grinding device 29′ that can be connected to the container 9′. As the dosing and grinding device 29′ is driven by the actuating and/or drive device 39, which is arranged in the dosing and grinding device receiving area 27′ within the first receiving area 5′, the coffee beans can be moved from the first container 9′ into the Dosing and grinding device 29′ are introduced and correctly dosed by this and ground to coffee powder. The device 1′ also comprises the second receiving area 7′, which is designed to receive the second container 11. The fluid can be correctly dosed by means of the clamping elements 155 which are arranged in the second receiving area 7′. With the device 1′, the ground coffee powder from the dosing and grinding device 29′ and the fluid from the second container 11 can be fed to a preparation device and introduced into a container, in particular into a filter container, in the correct mixing ratio. Thus, the device 1′ enables a simplified, correct and safe preparation of coffee.
