DETAILED DESCRIPTION OF THE INVENTION
(11) The invention is explained below with reference to the drawings for the sake of example.
(12) FIGS. 1 and 1b show an embodiment of a proposed container 11 as an attachment for a second container 13, which is embodied as a bottle in the present exemplary embodiment. The container 11 has a chamber 21 for receiving a mixture component and a part referred to as an adapter 51. The adapter 51 serves to connect the container 11 to the second container 13 on the one hand in order to add the mixture component to the latter. On the other hand, the adapter 51 fulfills the purpose of opening the chamber 21 of the container 11, thus releasing the mixture component so that it can flow through the flow channel 65 of the adapter 51 into the second container 13. The adapter 51 is non-detachably connected via a first connecting means 61 to the chamber 21 and also has a second connecting means 63 for attachment to the second container 13. The second connecting means 63 is a thread, particularly an internal thread, for attachment to a corresponding thread, particularly an external thread, at the opening of the second container 13. The latter is generally a bottle with a neck or port having the described thread. The first connecting means 61 enables the chamber 21 to move toward the adapter 51. In the present example, the chamber 21 can be moved into the adapter 51, the first connecting means 61 producing a restraint-guided rotational movement of the chamber 21 relative to the adapter 51 upon convergence of the chamber 21 and the adapter 51. Expediently, both the adapter 51 and the chamber 21 are substantially cylindrical at their mutually facing ends, the outer diameter or the outer contour of the chamber 21 at the described ends corresponding substantially to the Inner diameter or the inner contour of the adapter 51. As a result, the chamber 21 can be partially pushed into the adapter 51, i.e., into its one opening 55, and rotated. At the end facing toward the adapter 51, the chamber 21 has a base 23 with one or more weakened areas or thinned portions 25. Expediently, the weakened area 25 is substantially circular. It runs substantially along the inner edge of the chamber 21 or at least at a substantially constant distance thereto. The weakened area 25 is embodied so as to cooperate with a blade element 71 which is arranged in the adapter 51 between the first connecting means 61 and the second connecting means 63. The blade element 71 is stationary and/or immobile with respect to the adapter 51. The blade element 71 is part of the adapter 51 and/or if the blade element 71 and the adapter 51 are integrally formed. If the chamber 21 now moves toward the adapter 51 or Into same, the base 23 comes Into contact with the blade element 71, I.e., with its blade 73, particularly at the location of the weakened area 25. Through the rotational movement of the chamber 21, the blade 73 Is guided along the weakened area 25 and opens the base 23 of the chamber 21 in a circular manner. The base 23 remains connected to the chamber 21 at one place in the final position of the blade 73 (i.e., when the base 23 is completely opened). The remaining connection between base 23 and chamber 21 enables the base 23 to fold into chamber 21 or out of the chamber 21. The base 23 is thus opened without falling off and possibly getting lost. In order to achieve this, various possibilities merit consideration. Expediently, the movement of the chamber 21 Into the adapter 51 and/or the rotational movement of the chamber 21 is limited. This can be brought about, for example, by the first connecting means 61. However, the movement of the chamber 21 into the adapter 51 can also be limited by the cooperation of a projection 41 with the edge 59 of the adapter 51. The projection 41, formed by an expansion of the chamber 21 In the present example, extends circumferentially in a circular manner on the side wall 31 of the chamber 21. When the chamber 21 moves in the direction of the adapter 51, the projection 41 moves nearer to the edge 59 of the adapter 51. The distance between projection 41 and edge 59 thus defines and limits how far the chamber 21 can be moved into the adapter 51, and the projection 41 forms a stop. In the unopened state, a spacer 17 can be provided between projection 41 and edge 59 that prevents a convergence of the projection 41 and the edge 59 and hence a convergence of the blade element 71 and the base 23 of the chamber 51. The spacer 17 is embodied so as to be removable, particularly removable by hand. The blade element 71 has an opening 56 that enables the mixture component flowing from the base 23 out of the chamber 21 into the adapter 51 to pass toward the opening 56, which leads to or transitions into the opening 54 of the second container 13. The opening 56 of the blade element 71 narrows in the direction of flow of the mixing component, i.e., in the direction from the chamber 21 toward the second container 13. The blade element 71 forms a sort of funnel 75, with its opening width on the side facing toward the second container 13 being smaller than the opening width of the opening of the second container 13. In the depicted example, the port or neck of the second container 13 Is received (In the (final) state connected to the adapter 51) between the side wall 53 of the adapter 51 and the funnel 75. This prevents the mixture component from getting into the area of the second connecting means 63, which would contaminate the bottleneck of the container 13. This is important particularly if the container 11 is to be removed after the mixture component has been added to the second container 13. After all, there are essentially two use variations. According to a first variant, the container 11 is connected to the second container 13 and, after the addition of the mixture component, a lid 49 (alternatively also a film) that seals the opening 27 of the chamber 21, removed, and the mixture present In the second container 13 can be poured out through the opening 54 of the second container 13 via the adapter 51 and the chamber 21. In this case, the container 11 has a safeguard to prevent removal of the container 11 from the second container 13. According to a second variant, the container 11 is removed from the second container 13 after the addition of the mixture component. In this case, the opening 27 or the presence of the removable lid 49 or of the film is not necessary. A contamination during removal of the container 11 can be prevented by the smaller opening width of the opening 56 In comparison to that of the opening 54 of the second container 13 (independently of the presence of a funnel 75). An additional improvement is achieved through the presence of the described funnel 75. Alternatively or in addition, a provision can be made (also Independently of the funnel shape) that the opening 56 of the blade element 71 has an edge protruding Into the opening of the second container 13 as shown in FIGS. 1a and 1b (blade element 71 protruding Into the opening of the second container 13). Improved tightness is also achieved through the described measure, and contact between the mixture component and the second connecting means 63 is also prevented. The seals 28 and 29 also comprise additional measures for improving the tightness. The seals 28, 29 are annular. The seal 28 extends along the weakened area 25 and can, like in the present exemplary embodiment, be embodied as part of the base 23. It conies Into contact with the blade 73 before or while the blade 73 comes into contact with the base 23 and/or begins to open the base 23. For example, the seal 28 can be nearer to the blade element 71 than the part of the base 23 coming into contact with the blade 73 or to be severed. For example, the weakened area 25 can be embodied as an area of the base with a lesser thickness. The thinner part of the base 23 can be arranged at a greater distance from the blade 73. An additional seal 29 is formed by the projection 41 and can also be arranged on, at, next to or along the projection. All that is relevant is that the edge 59 cooperate in a sealing manner with the projection 41 or with the part of the chamber 21 with which the edge 59 is in contact in this position during maximum convergence of (or minimum distance between) the chamber 21 and the adapter 51.
(13) FIGS. 2a and 2b represent a slightly modified variant of the container from FIGS. 1a and 1b. One difference from the design according to FIGS. 1a and 1b is the shape of the chamber 21. The chamber 21 expanded on the side facing away from the adapter 51. In particular, the inner diameter of the chamber 21 at that end is greater than the outer diameter of the adapter 51. In this way, a substantial increase in volume can be achieved without greatly increasing the length of the container 11.
(14) FIGS. 3a and 3b show two different views of the outside of the chamber 21 (corresponding to the chamber shown in FIGS. 1a and 1b). Clearly visible are the first connecting means 61 and the part thereof that is arranged on the chamber 21. Said part has a (first) guide track 33 that extents in the shape of a helix or a helicoid along the outside or side wall 31 of the chamber 21. Such a guide track 33 expediently runs around the chamber less than two times, particularly less than one time or one-half time. In the present exemplary embodiment, this guide track 33 defines the rotation angle of the chamber 21 relative to the adapter 51 necessary for the complete opening of the chamber 21. In particular, the guide track 33 forms a stop 76 at its end for the sliding projection 57 described further below, whereby the rotation angle is limited. Expediently, two or more such guide tracks 33 are provided, it being possible for them to be arranged in regular intervals along the periphery of the chamber 21. In FIGS. 3a and 3b, two guide tracks 33 of this type are provided on opposite sides of the chamber 21. This helical guide track 33 is used to screw the chamber 21 into the adapter 51, thus bringing the base 23 of the chamber 21 into contact with the blade 73 and moving it along the weakened area 25 in order to open the base 23. For this purpose, the adapter 51 is equipped with one sliding projection 57 (cf. FIG. 4) per guide track 33. Upon rotation of the chamber 21, it moves along the helical guide track 33, thus establishing a connection between the chamber 21 and the adapter 51, which enables the abovementioned rotatability of the chamber 21 relative to the adapter 51. Expediently, a step 37 is provided at the end of the helical guide track 33 nearer to the base 23 and/or further from the base 23 that offers a resistance to the movement of the sliding projection 57 in the guide track 33 (or beyond the step). After the resistance is overcomethrough a rotation in a predetermined direction in the present exemplary embodimentthe sliding projection 57 reaches a recess 77 embodied so as to correspond to the sliding projection 57. The stop 76 that prevents further rotation of the sliding projection 57 is arranged in the direction of rotation. Counter to the direction of rotation, the step 37 is embodied such that the sliding projection 57 can leave the recess 77 in a restraint-guided manner in the direction of the helical guide track 33 under resistance but without destruction. Depending on the structure of the step 37, the sliding projection 57 can be reversibly or irreversibly fixed in the recess 77. The steps 37, or the recesses 77 in conjunction with the sliding projections 57, bring about a stabilization or fixation of the position of the chamber in its position nearest and/or furthest from the adapter 51. Optionally, an additional (and shorter) guide track 35 is present for each helical guide track 33. This second, shorter guide track 35 also runs along the periphery of the chamber 21 on its outside 31 but expediently at a constant distance to the base-side end of the chamber 21. The shorter guide track 35 transitions into the helical guide track 35, particularly in the area of the end of the helical guide track 35 further from the base 23 of the chamber 21. This results in a fork. If the chamber 21 is rotated in the opposite direction after the rotating and opening of the base 23, the sliding projection 57 moves from the end of the helical guide track 33 into the shorter guide track 35 and reaches its free end, which forms a stop 76 for the sliding projection 57, thus enabling transmission of the torque to the adapter 51. In this way, the chamber 21 and the adapter 51 can be removed from or screwed off of the second container 13 merely by rotating the chamber 21.
(15) In the exemplary embodiment shown here, the chamber 21 and the adapter 51 with blade element 71 are each embodied in a single piece and made of plastic as a plastic injection-molded part, so that large quantities can be manufactured cost-effectively.
(16) FIGS. 5a and 5b show an embodiment of a container. Its distinctiveness lies in a niche 22 formed by the chamber 21 in which the blade 73 is arranged before the opening of the base 23 by the blade 73. For the sake of clarity, the cut edges are without hatching. The niche 22 can be formed by the base 23 and/or the side wall 31 of the chamber 21. The parts of the chamber 21 that form the niche 22 can also be referred to as a niche wall. Expressed generally, it can be advantageous if the blade 73 extends from one side of the plane 30 defined by the part of the base 30 to be opened in a circular manner, particularly before the opening of the base 23 by the blade 73 of the blade element. This makes it possible for the opening of the base 23 to occur as a result of a rotational movement of the chamber 21 relative to the adapter 51 without a movement of the chamber 21 toward the adapter 51 and/or into same occurring or having to occur. If the blade 73 is rotated relative to the adapter 51, it first severs the niche wall. Since the niche wall transitions into the base 23 of the chamber 21, the blade 73 then slides into the base 23 and severs it along its edge. A part 24 of the niche wall remains connected to the base 23 and the side wall 31 of the chamber 21. A rotation angle of the chamber 21 relative to the adapter 51 can be limited. Since the base 23 remains connected to the side wall 31 of the chamber 21, it cannot be lost or get into the second container, even if the rotation angle of the chamber 21 relative to the adapter 51 is greater than 360. The niche 22 can generally also be a hollow space.
