Description

[0025] Further features and advantages of an embodiment of the invention are described below with reference to the drawings. The same reference signs are used for identical or similar parts and for parts with identical or similar functions. The following are shown:

[0026] FIG. 1 a schematic sectional view of a system according to one embodiment of the invention in the assembled state; and

[0027] FIG. 2 a schematic side view of the inner container of the system in FIG. 1.

[0028] It is not necessary for a device according to the invention to have all the features described below. It is also possible for a device according to the invention to have only individual features of the exemplary embodiment described below.

[0029] The system comprises an outer container 1 and an inner container 2. A first wall of the inner container 2 surrounds a first interior 4, in which a first liquid is disposed. A second wall of the outer container 1 surrounds a second interior 3, in which a second liquid is disposed. The inner container 2 has a first opening region 6. The outer container 1 has a second opening region 7. Both the first opening region 6 and the second opening region 7 are closed by a lid 5. If the lid 5 is loosened, the first interior 4 is in fluidic connection with a surrounding area of the system via the first opening region 6 and the second interior 3 via the second opening region 7. A circumferential collar 8 protrudes outward from the first wall of the inner container 2.

[0030] The lid 5 is fastened to the outer container 1 with a screw connection. The lid 5 is fastened to the inner container 2 with a plug-in connection. The plug-in connection is a positive-locking connection, namely a snap-in connection. A circumferential edge of the inner container 2 is disposed within a circumferential groove of the lid. The connection can be loosened by deforming the lid 5.

[0031] The inner container 2 and the outer container 1 are closed by initially establishing the plug-in connection between the lid 5 and the inner container 2. The lid 5 is then placed on the outer container 1 and, at the same time, the inner container 2 is inserted into the second interior 3. This is only possible when the collar 8 is guided through a cross-section tapering means protruding inward from the wall of the outer container 1 in the second opening region 7. The outer border of the collar 8 and the inner border of the cross-section tapering means are matched to one another in such a way that the inner container 2 can only be guided through in one or more predefined orientations relative to the outer container 1. At the moment when the collar 8 is disposed in a plane with the cross-section tapering means, a twisting of the inner container 2 relative to the outer container 1 is no longer possible, apart from tolerances.

[0032] If the collar 8 has been guided through the cross-section tapering means, the external thread of the outer container 1 and the internal thread of the lid 5 come into contact with one another so that the screw connection between the lid 5 and the container 1 can begin to be established. This requires a rotation of the lid 5 relative to the outer container 1, which is possible, because the collar 8 is disposed below the cross-section tapering means.

[0033] However, a driver element 9 projects vertically from the collar 8. If the inner container 2 is disposed in the second interior 3 as in FIG. 1, the driver element 9 protrudes toward the cross-section tapering means. The rotational movement of the lid 5 relative to the outer container 1 causes a twisting of the inner container 2 relative to the outer container 1, since the lid 5 and the inner container 2 are connected to one another. As soon as the driver element 9 strikes the cross-section tapering means, further twisting of the inner container 2 relative to the outer container 1 is no longer possible, so that the inner container 2 is twisted relative to the lid 5 when the lid 5 is screwed further onto the outer container 1.

[0034] If the screw connection between the lid 5 and the outer container 1 is completely established, the state shown in FIG. 1 is achieved. If a user now wishes to consume the two liquids disposed in the first inner compartment 4 and the second inner compartment 3, they begin to loosen the screw connection by rotating the lid 5 relative to the outer container 1. Due to the twisting of the inner container 2 relative to the lid 5 when the screw connection is established, the collar 8 can no longer be guided through the cross-section tapering means when the screw connection is loosened. The collar 8 comes into contact with the cross-section tapering means and blocks movement of the inner container 2 out of the second interior 3. If the screw connection is loosened further, an ever-increasing force acts on the collar 8, which leads to a deformation of the lid, so that the connection between the lid 5 and the inner container 2 is loosened.

[0035] Since the inner container 2 has no further fastening, it can move freely in the second interior, and the liquids are exchanged in the first interior 4 and the second interior 3. The lid 5 can then be removed from the outer container 1 by further loosening the screw connection, as with a normal container, so that the user can consume the mixed liquids.
