[0133] FIG. 14 shows further embodiments of a separating region for a bag with two chambers.

[0134] Various embodiments of tempering modules 100, into each of which a bag 1 of baby food is at least partially insertable to tempering the baby food, are described below.

[0135] FIG. 1 shows a first embodiment of a bag 1. FIG. 1a) shows a top view of the bag 1, FIG. 1b) a sectional view of the bag 1 in the sectional axis B-B and FIG. 1c) a perspective view of the bag 1.

[0136] The bag 1 is preferably made of plastic (for example polyethylene or a composite film of polyethylene and polyamide) substantially in the form of a tube. In particular, the tube is made in one piece without seams and preferably has a longitudinal bag axis BL. Furthermore, the bag material may comprise thermally conductive particles, preferably aluminium and/or copper particles, which allow an improved tempering of the baby food in the bag 1.

[0137] The bag 1 comprises one chamber 2, which is accessible at a first end 9 via an opening 8. At a second end 13 of the bag 1, which is opposite to the first end 9, the bag 1 is closed, preferably by a welding seam. The longitudinal bag axis BL extends from the first end 9 to the second end 13 of the bag 1. In particular, the opening 8 is designed to be filled with a baby food. For example, pre-made baby milk or baby formula, or breast milk may be filled into the bag 1.

[0138] In order to close the chamber 2 for transport, the opening 8 in the bag 1 may be closed by means of an appropriate closure. For this purpose, a connecting element 4 may be provided at the opening 8. The connecting element 4 can thereby be formed as an circular element, which is preferably made of plastic. In particular, it is advantageous here if the connecting element 4, in contrast to the bag 1 itself, is designed to be rigid or to have a higher rigidity. In order to connect the connecting element 4 to the bag 1, the connecting element 4 may be welded to the bag 1.

[0139] As shown in FIG. 1b), the closure can be designed as a cover 20 which can be connected to the connecting element 4. The cover 20 may be connected to the connecting element 4 by means of a hooking or clicking mechanism. Alternatively, the connecting element 4 and/or the cover 20 may have one or more sealing lips which, when in contact with the other element, have both a sealing and a fixing function. FIG. 1b), on the other hand, shows a screw mechanism. On an outer surface 23 (“outside”) of the connecting element 4 and on an inner surface 25 of the cover 20 there is in each case, at least in some areas, a thread 27 which engages in one another or interacts with one another in the connection process. The outer surface 23 thereby preferably runs parallel to the longitudinal axis BL of the bag.

[0140] In particular, the connecting element 4 can also be used to be connected to a dispenser designed, for example, to dispense ready-made baby food into the chamber 2. In particular, it is preferred that the bag 1 is compatible with a dispenser such as published in the publication WO 2017/121638 A1 and/or in the German patent application DE 10 2018 009 551, which are incorporated herein by reference in their entirety. The connecting element 4 may be connected to the dispenser directly herein or by means of an adapter. The amount of baby food can be manually adjusted on the dispenser. Alternatively, the dispenser dispenses predetermined or pre-portioned units to the bag 1. However, the dispenser may also comprise a sensor that automatically detects a connected bag 1 and, additionally, the size of the bag 1. Alternatively, an RFID tag could be provided or incorporated in or on the connecting element 4 for this purpose. As soon as the dispenser recognizes a bag 1, a corresponding amount of a baby food can subsequently be dispensed automatically. Due to the compatibility with a dispenser, the chamber 2 can thus be filled quickly and precisely.

[0141] Alternatively or additionally, the connecting element 4 may be connected to a breast pump for expressing breast milk.

[0142] The bag size is thereby designed such that preferably between 50 ml and 300 ml of baby food can be filled in. A size which allows 250 ml of baby food to be filled in is particularly preferred. Furthermore, the bag 1 may be folded in certain areas so that the chamber 2 is reduced in size. The fold may be unfolded as required. The folded area can be fixed with an adhesive strip and/or a clip.

[0143] In order to be able to temper the filled baby food if necessary, the bag 1 is to be inserted into a tempering module 100, as shown for example in FIG. 2, whose tempering module interior 104 can be tempered. In particular, the tempering module interior 104 can be tempering led by a heated inner wall 112.

[0144] However, since the bag 1 is a flexible container, the bag 1 often has kinks where the bag 1 buckles. In other words, the bag 1 itself cannot be held in an upright position. In particular, at the buckling points, in a state inserted into the tempering module 100, air is present between the bag 1 and the inner wall 112 of the tempering module 100, which has an insulating effect and thus deteriorates or slows down heat transfer to the bag 1 or the baby food.

[0145] In order to ensure that such kinks are avoided and that the bag 1 lies flat against the inner wall 112 of the tempering module 100, the bag 1 comprises various tensioning devices which can hold the bag 1 in an upright position in the tempering module 100.

[0146] As shown in FIGS. 1b) and 1c), the bag 1 according to the first embodiment has a first tensioning device 40 on the connecting element 4, which is formed as a tensioning projection 42, running around at least in some areas. The at least in some areas circumferential tensioning projection 42 is located, on the outer surface 23 of the connecting element 4, so that the diameter of the connecting element 4 is increased by the tensioning projection 42 which is formed around at least in some areas.

[0147] Additionally, the bag 1 comprises a second tensioning device 44 at the second end 13 of the bag. The second tensioning device 44 comprises a tensioning plate 46, which is fastened to a base surface 48 of the bag 1. At least one magnet 31 is located on or in the tensioning plate 46.

[0148] FIG. 2 shows a first embodiment of a tempering module 100 in which, for example, the bag 1 according to FIG. 1 can be inserted and which comprises tensioning devices which can be connected to the tensioning device of the bag 1 in order to hold the bag 1 in an upright position in the tempering module 100. In particular, this allows the bag 1 to be held flat against the inner wall 112 of the tempering module 100 to ensure rapid heating of the baby food.

[0149] FIG. 2a) shows a top view of the tempering module 100, FIG. 2b) a sectional view of the tempering module 100 in the sectional axis B-B and FIG. 2c) a perspective view of the tempering module 100.

[0150] The tempering module 100 comprises a tempering module housing 102, which is preferably rotationally symmetrical in shape. However, only the tempering module interior 104 may be rotationally symmetrical in shape, while the exterior shape of the tempering module housing 102 is freely selectable. In addition, the tempering module housing 102 has a tempering module base surface 106. On a side opposite to the tempering module base surface 106, there is a tempering module insertion opening 108 via which the bag 1 is at least partially insertable into the tempering module 100.

[0151] During the tempering process, the tempering module insertion opening 108 may be closed by a cover (not shown). However, it is also possible that a nipple positioned on the bag 1 and which can be connected to the connecting element 4 substantially closes the tempering module insertion opening 108. In particular, it is preferred that the diameter of the circumferential tensioning projection 42 on the connecting element 4 is larger than the diameter of the tempering module insertion opening 108, so that the connecting element 4 can be prevented from covering into the tempering module interior 104. In this case, the circumferential tensioning projection 42 would rest on a circumferential edge 109 of the tempering module 100, which outwardly limits the tempering module insertion opening 108. Alternatively, as shown in FIG. 2b), the diameter D of the tempering module interior 104 may expand in an area adjacent the tempering module insertion opening 108 to form a step as a tensioning support surface 111. It is preferred that the diameter D of the tempering module interior 104 is expanded from the tempering module insertion opening 108 to the tensioning support surface 111. When the bag 1 is inserted into the tempering module interior 104, the circumferential tensioning projection 42 can rest on the tensioning support surface 111 so that the connecting element 4 can be prevented from covering into the tempering module interior 104. According to an embodiment, the circumferential edge 109 of the tempering module 100 and the tensioning support surface 111 thus serve as a “first tensioning device”. To lock the bag 1 in the tempering module 100, the tensioning projection 42 may be clicked onto the circumferential edge 109 or the tensioning support surface 111.

[0152] More preferably, the tempering module 100 has a height H of from about 80 mm to about 130 mm. Preferably, the wall thickness of the tempering module 100 is in a range between about 0.5 mm and about 1.0 mm. A wall thickness of about 0.8 mm is particularly preferred. The diameter D of the tempering module 100 is preferably between about 45 and about 70 mm.

[0153] The height H of the tempering module interior 104 is preferably set such that the bag 1 can be arranged in a preferably stretched position in the tempering module interior 104. In this way, a faster tempering of the contents of the bag 1 or of the baby food can be achieved. The height H of the tempering module interior 104 can thereby either be defined by the length of the tempering module 100 as such, or can be combined as desired by tempering module extension elements. The individual tempering module extension elements may be clicked together or screwed together. If the tempering module 100 has multiple extension elements, the uppermost extension element has the first tensioning device.

[0154] At least one heating element is arranged on at least one portion of the inner wall 112 of the tempering module housing 102. The heating element can heat the inner wall 112 of the tempering module housing 102, preferably the heating element is located outside the tempering module interior 104. In other words, the inner wall 112 can be tempered from the outside by the heating element and the heat is transferred to the tempering module interior 104 via the inner wall 112. Preferably, the heating element may be formed as a heating mat 122 that overlaps the inner wall 112 of the tempering module housing 102, at least in some areas. Alternatively, the heating element may be formed as a heating plate, heating foil, or heating board. In the following, however, only the heating mat 122 is discussed by way of example. However, the explanations also apply to the other alternatives of a heating element.

[0155] Preferably, the inner wall 112 of the tempering module housing 102 is at least partially made of a thermally conductive material, such as aluminum or copper. For this purpose, the inner wall 112 may be manufactured as a tubular element made of aluminum or copper. As manufacturing tolerances for the diameter of the tubular element, +/−1 mm is preferred. Via this, the heat generated by the heating mat 122 can be substantially evenly distributed via the tempering module housing 102 and delivered into the tempering module interior 104. Thus, the contents of the bag 1 or the baby food can be heated evenly.

[0156] In order to achieve the fastest possible tempering of the content of the bag 1 or the baby food, the tempering module interior 104 is dimensioned in relation to the bag 1 such that the bag 1 is in surface contact with the inner wall 112 when inserted. The more surface area of the bag 1 in contact with the inner wall 112, the faster heating can occur. If the tempering module housing 102 comprises a plurality of tempering module extension elements 110, each tempering module extension element 110 preferably comprises at least one heating element. In order to provide power to each of the heating elements on the tempering module extension elements 110, it is necessary to provide connectivity between the tempering module extension elements 110 that allows power to be transferred to the individual heating elements.

[0157] As already mentioned above, it is additionally advantageous if heat-conducting particles are incorporated into the material of the bag 1. These enable an even better transfer of heat to the baby food. The particles can be aluminium or copper particles.

[0158] In addition, at least one magnet 116 may be arranged in the tempering module base surface 106 as a “second tensioning device” which, in the inserted state, interacts with the at least one magnet 31 of the bag 1 (see, for example, FIG. 1b)). The magnet 31 in or on the tensioning plate 46 of the bag 1 is arranged adjacent to the tempering module base surface 106 in the inserted state of the bag 1. This fixes the bag 1 to the tempering module base surface 106.

[0159] By the interaction of the tensioning device of the bag 1 and the tensioning devices of the tempering module 100, the bag 1 is held in an upright position and the bag 1 can be held flat against the heatable inner wall 112 of the tempering module 100. Thus, rapid heating of the baby food is possible.

[0160] FIG. 3 shows a second embodiment of a bag 1. FIG. 3a) shows a top view of the bag 1, FIG. 3b) a sectional view of the bag 1 in the sectional axis D-D and FIG. 3c) a perspective view of the bag 1.

[0161] The second embodiment of the bag 1 differs from the first embodiment of the bag 1 only in the second tensioning device 44. The rest of the embodiment of the bag 1 remains the same, so that only the differences are described here.

[0162] In particular, the second embodiment of the bag 1 does not comprise a tensioning plate 46 with at least one magnet 31, but a tensioning strap 50 which is attached to the base surface 48 of the bag 1. Preferably, the tensioning strap 50 extends in the bag's longitudinal axis BL.

[0163] The tensioning strap 50 may include one or more locating apertures 52 in the bag's longitudinal axis.

[0164] FIG. 4 shows a second embodiment of a tempering module 100 in which, for example, the bag 1 of FIG. 3 can be inserted and which comprises tensioning devices which can be connected to the tensioning device of the bag 1 of FIG. 3 in order to hold the bag 1 in an upright position in the tempering module 100. In particular, this allows the bag 1 to be held flat against the inner wall 112 of the tempering module 100 to ensure rapid heating of the baby food.

[0165] FIG. 4a) shows a top view of the tempering module 100, FIG. 4b) a sectional view of the tempering module 100 in the sectional axis D-D and FIG. 4c) a perspective view of the tempering module 100.

[0166] The tempering module 100 according to the second embodiment differs here only from the tempering module 100 of the first embodiment in the second tensioning device, so that only the second tensioning device is described here.

[0167] In particular, the second tensioning device here comprises a tensioning opening 118 in the tempering module base surface 106. The tensioning aperture 118 can be used to guide the tensioning strap 50 out of the tempering module interior 104. By pulling on the tensioning strap 50, the base surface 48 of the bag 1 can be pulled towards the tempering module base surface 106 to hold the bag 1 in an upright position in the tempering module 100 and ensure rapid heating. Preferably, in order to avoid heat loss via the tensioning opening 118, the 118 is only slightly larger than the tensioning strap 50. Preferably, a rubber seal is attached to the tensioning opening 118.

[0168] The tensioning strap 50 may be fastened to a bottom side 120 of the tempering module 100 by means of one of the fixing apertures 52. A corresponding fixing pin may be provided here on the bottom side 120 of the tempering module 100, which pin engages in the fixing aperture 52.

[0169] By the interaction of the tensioning device of the bag 1 and the tensioning devices of the tempering module 100, the bag 1 is again held in an upright position and the bag 1 can be held flat against the heatable inner wall 112 of the tempering module 100. Thus, rapid heating of the baby food is possible.

[0170] FIG. 5 shows a third embodiment of a bag 1. FIGS. 5a) and 5d) each show a top view of the bag 1, FIGS. 5b) and 5e) show a sectional view of the bag 1 in the sectional axis F-F and FIGS. 5c) and 5f) show a perspective view of the bag 1.

[0171] The third embodiment of the bag 1 differs from the first and second embodiments of the bag 1 only in the second tensioning device 44. The rest of the embodiment of the bag 1 remains the same, so that only the differences are described here.

[0172] The opening 8 of the bag 1 at the first end 9 of the bag 1 is here a first opening 11, and the tensioning projection 42 is formed around at least in some areas, on the connecting element 4 is referred to as a first tensioning projection 58. However, in this embodiment the bag 1 is not closed at the second end 13 of the bag 1, but has a second opening 15.

[0173] The second opening 15 is closed by means of a tensioning cover 54. In order to form the second tensioning device 44, the tensioning cover 54 has a second tensioning projection 62 formed around at least in some areas on an outer side 60. In this regard, the outer side 60 preferably extends parallel to the longitudinal bag axis BL. In particular, the tensioning cover 54 may be rotationally symmetrical.

[0174] If the second tensioning projection 62 is only formed in sections, the individual sections may be of equal or different sizes. The distances between the sections may be of equal or different sizes. In particular, the sections may be aligned with sections of the first tensioning projection 58 with respect to the longitudinal direction of the bag BL, or may be offset from each other.

[0175] In one aspect, the tensioning cover 54 can close the second opening 15 in such a way that the second opening 15 cannot be opened, as shown in FIGS. 5a) to 5c). In this regard, the tensioning cover 54 may preferably be formed in one piece and be fixedly connected to bag 1. However, as shown in FIGS. 5d) to 5f), the tensioning cover 54 may also be formed in two parts. Here, the connecting element 4 becomes a “first connecting element” 17 and the tensioning cover 54 itself has a second connecting element 19. On the second connecting element 19, which is connected to the bag 1, the second tensioning projection 62 is located here on the outer surface 56 thereof. The outer surface 56 of the second tensioning projection 62 preferably extends parallel to the longitudinal axis BL of the bag. Furthermore, it is preferred that the first and second connecting elements 17, 19 are identically formed. The second connecting element 19 can be closed with a closure corresponding to the first connecting element 19. As shown in FIG. 5b), the second opening 15 can be closed with a cover 21 which is screwed onto the second connecting element 19. However, other closure mechanisms as already described above are also possible here.

[0176] FIG. 6 shows a third embodiment of a tempering module 100 in which, for example, the bag 1 of FIG. 5 can be inserted and which comprises tensioning devices which can be connected to the tensioning devices of the bag 1 of FIG. 5 in order to hold the bag 1 in an upright position in the tempering module 100. In particular, this allows the bag 1 to be held flat against the inner wall 112 of the tempering module 100 to ensure rapid heating of the baby food.

[0177] FIG. 6a) shows a top view of the tempering module 100, FIG. 6b) a sectional view of the tempering module 100 in the sectional axis F-F and FIG. 6c) a perspective view of the tempering module 100.

[0178] The tempering module 100 according to the third embodiment differs here only from the tempering module 100 of the first embodiment and second embodiment in the second tensioning device, so that only the second tensioning device is described here.

[0179] As shown in FIG. 6b), in the third embodiment, the diameter D of the tempering module interior 104 expands adjacent the tempering module base surface 106 to form a step in the interior wall 112. The increase in diameter D forms a circumferential tensioning recess 124 as a second tensioning device in the tempering module 100. Preferably, the tensioning recess 124 extends with respect to a longitudinal axis L of the tempering module from the step to the tempering module base surface 106. The longitudinal axis L of the tempering module 100 extends from the tempering module insertion opening 108 to the tempering module base surface 106.

[0180] The circumferential tensioning recess 124 is configured to allow the second tensioning projection 62 of the bag 1 to be inserted. To enable such insertion, the tempering module 100 may be openable. For this purpose, the tempering module housing 102 may be divided in two with respect to the longitudinal axis L. A portion of the tempering module housing 102 may be removable or pivotable by a hinge 114 extending in the longitudinal axis L, as shown in FIG. 6.

[0181] By the interaction of the tensioning device of the bag 1 and the tensioning devices of the tempering module 100, the bag 1 is again held in an upright position and the bag 1 can be held flat against the heatable inner wall 112 of the tempering module 100. Thus, rapid heating of the baby food is possible.

[0182] FIG. 7 shows a fourth embodiment of a bag 1. FIG. 7a) shows a top view of the bag 1, FIG. 7b) a sectional view of the bag 1 and FIG. 5c) a perspective view of the bag 1.

[0183] The fourth embodiment of the bag 1 differs from the third embodiment of the bag 1 only in the second tensioning device 44. The remaining embodiment of the bag 1 remains the same, so that only the differences are described here.

[0184] More specifically, the second tensioning device 44 here additionally comprises at least one tensioning strut 64 extending in the longitudinal bag axis BL and connected to the first and second tensioning projections 58, 62. Likewise, it is possible that the tensioning strut 64 is integrally formed with the first and second tensioning projections 58, 62.

[0185] As described above, the tensioning projections 58, 62 may be formed to be either fully circumferential or only circumferential in certain areas. In particular, as shown in FIGS. 7a) to c), the portions of the tensioning projections 58,62 may be formed only where the tensioning struts 64 are formed. FIG. 7 shows four tensioning struts 64 arranged uniformly around the bag 1. However, the tensioning struts 64 can also be at different distances from one another.

[0186] FIG. 7b) shows here a tensioning cover 54 which is designed to be openable. As already described with regard to FIG. 5, the tensioning cover 54 can also be designed in such a way that the second opening 15 is firmly closed by the tensioning cover 54 and thus cannot be opened.

[0187] FIG. 8 shows a fourth embodiment of a tempering module 100 in which, for example, the bag 1 of FIG. 7 can be inserted and which comprises tensioning devices which can be connected to the tensioning device of the bag 1 of FIG. 7 in order to hold the bag 1 in an upright position in the tempering module 100. In particular, this allows the bag 1 to be held flat against the inner wall 112 of the tempering module 100 to ensure rapid heating of the baby food.

[0188] FIG. 8a) shows a top view of the tempering module 100, FIG. 8b) a sectional view of the tempering module 100 and FIG. 8c) a perspective view of the tempering module 100.

[0189] Contrary to the previously described embodiments of the tempering modules 100, the tempering module 100 of the fourth embodiment has a constant diameter D. However, the inner wall 112 here has, as a tensioning device, at least one tensioning recess 126 extending along the longitudinal direction L of the tempering module 100. In particular, the tensioning recess 126 is configured such that a corresponding tensioning strut 64 can be inserted into the tensioning recess 126. Preferably, for this purpose, the tensioning strut 64 extends from the tempering module insertion opening 108 to the tempering module base surface 106.

[0190] By the interaction of the tensioning device of the bag 1 and the tensioning device of the tempering module 100, the bag 1 is again held in an upright position and the bag 1 can be held flat against the heatable inner wall 112 of the tempering module 100. Thus, a rapid heating of the baby food is possible.

[0191] All of the embodiments of the bag 1 already described each have one chamber 2. However, the bag 1 may also have at least two chambers, as will be shown below.

[0192] FIG. 9 shows the first embodiment (see FIG. 1) of the bag 1 with two chambers.

[0193] FIG. 9 shows a bag 1 for the production of baby food according to a preferred embodiment. For the production of baby food, various baby food concentrates from different manufacturers are commercially available, which, when mixed with water, produce the required baby food. The baby food concentrate is typically in powder form. In particular, the baby food concentrate may be milk powder or a puree powder.

[0194] The bag 1 has at least one first chamber 3 and a second chamber 5, which are arranged in the bag longitudinal direction BL. FIG. 9 shows a sectional view in the longitudinal direction of the bag BL. The chambers 3, 5 are separated or separated from each other by a separating region 7, wherein the separating region 7 preferably has at least one welding seam. As shown in FIG. 9, the separating region 7 creates a necking in the bag 1.

[0195] The opposite or opposing ends of the bag 1 with respect to the bag longitudinal direction BL have openings. Specifically, at the first end 9 of the bag 1 adjacent to the first chamber 3 the first opening 11 is formed, while at the second end 13 (opposite to the first end 9) of the bag 1 adjacent to the second chamber 5 the second opening 15 is formed. The openings 11, 15 may be of the same size or of different sizes. In particular, the openings 11, 15 serve for filling the respective chambers 3, 5. The first chamber 3 is designed to be filled with a baby food concentrate, whereas the second chamber 5 is designed to be filled with a fluid. The fluid may be, for example, water (specifically sterile water) which, when mixed with the baby food concentrate, produces a baby milk or a baby puree. Preferably, the bag 1 is filled in advance (for example, already at home) to provide a pre-portioned bag 1 for a later time (for example, on the go).

[0196] In order to close the chambers 3, 5 for transport, the individual openings 11, 15 in the bag 1 can be closed by means of corresponding closures. For this purpose, the first connecting element 17 may be provided at the first opening 11 and the second connecting element 19 may be provided at the second opening 15. The connecting elements 17 and/or 19 can thereby be formed as circular elements, which are preferably made of plastic. In particular, it is advantageous in this case if the connecting elements 17, 19, in contrast to the bag 1 itself, are designed to be rigid or to have a higher rigidity. In order to connect the connecting elements 17, 19 to the bag 1, the connecting elements 17, 19 can be welded to the bag 1. On the first connecting element 17 there is the at least partially circumferential tensioning projection 42 as described above with respect to FIG. 1.

[0197] As shown in FIG. 9, the closure or closures may be in the form of cover s 21, each of which is which can be connected to the connecting elements 17, 19. The cover s 21 may be connected to the connecting elements by means of a hooking or clicking mechanism. Alternatively, the connecting elements 17, 19 and/or the cover s 21 may have one or more sealing lips which, when in contact with the respective other element, have both a sealing and a fixing function. FIG. 9, on the other hand, shows a screw mechanism. On the outer surface 23 of the connecting element 17 or 19 and on an inner surface 25 of the cover 21 there is in each case, at least in some areas, a thread 27 which engages in one another or interacts with one another in the connecting process.

[0198] In particular, the connecting element 17 or 19 can also be used to be connected to a dispenser designed, for example, to dispense a baby food concentrate into the first chamber 3. In particular, it is preferred that the bag 1 is compatible with a dispenser such as published in the publication WO 2017/121638 A1 and/or in the German patent application DE 10 2018 009 551, which are incorporated herein by reference in their entirety. The connecting element 17 and/or 19 may be connected to the dispenser directly herein or by means of an adapter. The amount of baby food concentrate may be manually adjusted at the dispenser. Alternatively, the dispenser dispenses predetermined or pre-portioned units to the bag 1. However, the dispenser may also comprise a sensor that automatically detects a connected bag 1 and, in a complementary manner, the size of the bag 1. In particular, based on the size of the connected connecting element 17, 19 the dispenser could detect whether it is the powder chamber or water chamber. Depending on which chamber the dispenser detects, the dispenser then dispenses either water or powder. The size of the connected connecting element 17, 19 may thereby also provide information to the dispenser as to how much water or powder is to be dispensed. Alternatively, an RFID tag could be provided or incorporated in or on the connecting element 17, 19 for this purpose. Once the dispenser detects a bag 1, a corresponding amount of a baby food concentrate can subsequently be dispensed automatically. This is also possible with respect to the second chamber 5 and the supply of a fluid. Thus, by being compatible with a dispenser, the chambers 3, 5 can be filled quickly and precisely.

[0199] If baby food is now required at a later time (e.g. while travelling, for example), only the separating region 7 can be at least partially opened. For this purpose, it is sufficient if force is applied to the bag 1 from the outside. If the separating region 7 is formed, for example, by a welding seam, the force is to be applied in such a way that the bag sides, which are connected to one another by the welding seam, at least partially separate from one another again as a result of the force applied. However, the bag sides themselves are not damaged in the process, so that leakage of the filled components is avoided. Once the separating region 7 has been opened, the filled components can be mixed together, so that subsequently the baby food is produced. Preferably, the bag 1 can be shaken.

[0200] The force to be applied may, for example, be applied by pushing on the bag 1 and/or by pulling the bag 1 substantially in the longitudinal direction of the bag BL.

[0201] Before or after opening the separating region 7, on one side of the bag 1, the cover 21 can be replaced specifically by a nipple. As soon as the separating region 7 is opened and the individual components are mixed in the bag 1, the baby can consume the baby food directly from the bag 1.

[0202] Contrary to the first embodiment of the bag 1 with one chamber, the at least one magnet 31 is here not arranged in a tensioning plate 46, but in the closure which closes the second opening 15. FIG. 9 shows a cover 21 on or in which the at least one magnet 31 is arranged as a second tensioning device 44.

[0203] FIG. 10 shows a bag 1 with two chambers according to the second embodiment.

[0204] The bag 1 is formed here as described with respect to FIG. 9. However, here there is no magnet as a second tensioning device 44 in the cover 21 for closing the second opening 15. Rather, here the tensioning strap 50 is attached to the cover 21.

[0205] FIG. 11 shows a bag 1 with two chambers according to the third embodiment.

[0206] The bag 1 is formed here as described with reference to FIG. 9. However, here there is no magnet as a second tensioning device in the cover 21 for closing the second opening 15. Rather, here the second tensioning projection 62 is arranged or formed on the second connecting element 19.

[0207] FIG. 12 shows a bag 1 with two chambers according to the fourth embodiment. This is identical to the bag 1 according to FIG. 7, but in contrast to FIG. 7 it has two chambers.

[0208] All embodiments described with two chambers can also be designed without a separating region 7 and consequently be used as a bag with only one chamber.

[0209] In order to supply the tempering module 100 with energy to control the temperature of the baby food, the tempering module 100 can be connected to a connection unit 200, as shown in FIG. 13.

[0210] For this purpose, tempering module connection contacts may be arranged in the tempering module base surface 106, via which the tempering module 100 may be connected to the connection unit 200. In particular, the heating mat 122 can thereby be connected.

[0211] In particular, the tempering module 100 is configured such thon the tempering module 100 can additionally be used as a holding device for the bag 1. In particular, after the baby food has been tempered in the bag 1, the baby can drink directly from the bag 1 which is held in the tempering module 100. Via this, the user can hold a stable element resembling a bottle while the flexible bag 1 is arranged inside the tempering module 100.

[0212] In the following, the connection unit 200 will now be described, which is shown, for example, in FIG. 13 (see steps 3 and 4 of the tempering process).

[0213] The connection unit 200 comprises a connection unit housing 202, the upper surface of which is a connection surface 204 onto which the tempering module 100, specifically the tempering module base surface 106, can be positioned. Preferably, the tempering module 100 can be clicked onto the connecting surface 204 using a click mechanism. This allows the tempering module 100 to be securely connected to the connection unit 200. Furthermore, the click mechanism can already be used to start the tempering process as soon as the tempering module 100 is clicked onto the connection surface 204.

[0214] Preferably, at least one rechargeable battery (e.g. a lithium polymer battery) is arranged inside the connection unit housing 202. This serves as an energy storage device, which supplies energy to the tempering module 100 when required to supply the heating element with power. The rechargeable battery makes it possible to always have energy available for tempering baby food, even when on the move—independently of a power socket. E.g. by means of a USB connection or a conventional power cable, the rechargeable battery can be at least partially charged again. The battery as well as the heating mat 122 are preferably designed in such a way that both liquid and frozen baby food can be heated in the tempering module 100.

[0215] Furthermore, a control unit may be arranged in the interior of the connection unit housing 202, which is connected to the battery in order to start and stop a tempering process by delivering energy to the heating element or by stopping the delivery. The duration of the tempering process may be determined by a fixed predefined time, or may occur as a function of an achieved temperature that has been reached in the tempering module interior 104. For this purpose, a sensor may be provided in the tempering module interior 104 which measures the temperature in the tempering module interior 104 (e.g. regularly or at different times) and transmits the measured data to the control unit. Depending on the measured temperatures, the control unit then controls the further tempering process. This function can also be used to maintain baby food in the tempering module 100 substantially at a predetermined or predeterminable temperature. For example, the desired temperature may be set at the connection unit 200. In addition, switches may be located on the connection unit 200 to trigger a start and/or stop of the tempering process. Alternatively or additionally, the connection unit 200 may be controllable via an app.

[0216] Alternatively, the tempering module 100 may be powered directly by means of a cable and a power outlet.

[0217] FIG. 13 shows specifically that a nipple 29 is connected to a connecting element 4, 17, 19. This protrudes from the tempering module 100 during the tempering process and can be used to consume the baby food after the tempering process. The bag 1 preferably remains in the tempering module 100 as a holding device.

[0218] In the embodiments of a bag 1 with two chambers described so far, the separating region 7 was preferably produced by means of a welding seam. In the following, further possibilities will be shown.

[0219] As shown in FIG. 14a), the separating region 7 may also have at least one folding edge 34. At the folding edge 34, the bag 1 is folded in the separating region 7 by an angle of up to about 180°, preferably so that the first chamber 3 and the second chamber 5 lie substantially on top of each other. The folded state is specifically fixed by a fixing adhesive tape 36, which is specifically arranged in the separating region 7 to fix the folded area. If the individual components are to be mixed to form a baby food, the first chamber 3 and second chamber 5 can be unfolded so that the separating region 7 is opened.

[0220] Further, the separating region 7 between the first chamber 3 and the second chamber 5 may comprise a clamp that clamps the bag 1 in the separating region 7. By opening the clamp, the separating region 7 is opened.

[0221] As a still further alternative, the separating region 7 may be formed by twisting the bag 1 in the separating region 7. The twisted state of the bag 1 may be fixed by a seal 38 (e.g. adhesive tape). If the user pulls on the bag 1 substantially in the longitudinal direction of the bag BL, the seal 38 breaks and the twist of the bag 1 may be released, allowing the components contained in the bag 1 to mix. In addition to the twist, the bag 1 may be folded as described above, as shown in FIG. 14b).
