Multi-chamber container

The invention relates to a multi-chamber container with an outer and inner container for pourable substances to be kept separately , wherein the substances can be brought together within the container for the purpose of removing a mixture of substances.

Such containers are known in a wide variety of designs and have the disadvantage that they are complicated in structure, cumbersome to handle and difficult to assemble.

The object of the invention is therefore to create a multi-chamber container according to the preamble of claim 1, which does not have these disadvantages.

15

This object is achieved according to the characterizing part of claim 1. Further advantageous embodiments of the invention emerge from the subclaims.

Advantageously, the combining of the substances in the multi-chamber container for the purpose of producing a substance mixture is achieved by

&rgr; projections on the inner wall of the outer container

which communicate with the outer wall projections of the inner container in such a way that the projections

> are arranged on diametrically opposite sides,

that when the cap is turned, the projections are axially displaced and the inner container is released from the cap connection and falls with its contents into the outer container

falls. By shaking the multi-chamber container, a homogeneous mixture of substances can be achieved through the loose inner container. To remove this mixture, the cap is opened.

Depending on requirements, the projections can be designed in different ways, e.g. the outer container projections have a horizontally oriented plane on the underside, but the inner container projections have a radial, inclined plane on the top, or the outer container projections have an inclined plane on the underside, but the inner container projections have a radial, horizontal plane on the top.

In another embodiment of the projections, these are designed in such a way that the outer container projections have symmetrical wedge-shaped inclined planes on the underside, but the inner container projections have a horizontal plane on the top, whereby any direction of rotation of the cap is possible for the separation process. The same applies if the outer container projections have a horizontal plane on the underside and the inner container projections have symmetrical wedge-shaped inclined planes on the top.

By means of the upper (symmetrical wedge-shaped) inclined planes of the outer container projections, it is advantageously achieved that when the inner container is inserted into the outer container, the inner container is forcibly oriented by means of the inner container projections by the outer container projections in such a way that the inner container connected to the cap can be freely inserted into the outer container.

For a simple construction ^, the inner container is cup-shaped.

The cap of the inner container has a sealing ring on the inside.

In a further embodiment of the invention, it is provided that the inner container has an axial projection towards its open side, which forms a rotationally fixed and axially detachable connection with the cap, e.g. in such a way that the projection has a polygonal profile in its end region, whereby the beginning of the removal channel of the cap has a complementary polygonal profile for the purpose of a rotationally fixed connection with the cap.

An improved rotationally fixed and axially detachable connection is achieved in that two diametrically opposed projections are arranged on the outside of the projection, which communicate with a transverse, funnel-shaped recess of a hollow-cylindrical centering aid, whereby the connection position of the inner container with the cap is fixed and that the inner container is forced into the recess by the two projections using the centering aid during the connection process.

In another advantageous development of the invention, it is provided that the projection in its end region is designed as a plug that closes the removal channel, thereby preventing incorrect removal of only an unmixed substance, or that substance removal from the multi-chamber container is only possible when both substances have been brought together by turning the cap.

Within the scope of the invention, it can be provided to design the inner container with several concentrically arranged cylindrical chambers, whereby more than two different substances can be kept separate.

-A-

A further advantageous embodiment of the invention can be seen in that the projection is designed as a tube and is designed such that it connects the removal channel with the outer container chamber, whereby a predetermined limited partial removal from the outer container chamber is made possible.

Advantageously, the projection and the inner container are formed as one piece and can therefore be manufactured cost-effectively.

A targeted and dosed application of the substance mixture is achieved by designing the outer container so that it can be compressed. This can be achieved by either designing the outer container with an elastic wall or by designing the outer container wall in an algae shape.

In the following, the invention is described by means of several embodiments using figures, some of which are shown schematically.

9. A further sealing ring 10 seals the outer container chamber 3 in a liquid-tight manner. The inner container 5 has two diametrically opposed projections 11, 12 on the outer wall; the outer container 4 has two diametrically opposed projections 13, 14 on the inner wall. The projections 11, 12, 13, 14 are arranged in such a way that they communicate with one another by turning the cap 6 in such a way that the inclined projections 11, 12 are pushed axially downwards by the lower string of the outer container projections 13, 14 during the turning process of the cap 6, thereby axially releasing the inner container 5 from the cap 6. In the embodiment shown here, a counterclockwise rotation must be carried out to release the inner container. By shaking the multi-chamber container 1, the substances can now be mixed. The loose inner container 5 supports the mixing process while the multi-chamber container 1 is being shaken. To remove the substance mixture, the closure 15 is removed from the cap 6.

A rotationally fixed connection of the inner container 5 with the cap 6 is achieved in that the inner container 5 has an axial projection 16 towards its open side, which is provided with a polygonal profile 17 in its end region, whereby the beginning of a removal channel 18 of the cap 6 has a complementary polygonal profile to accommodate the projection 16.

■2

The axial projection 16 is designed in such a way that it serves as a plug closing the removal channel 18. This measure prevents incorrect removal of only one substance from the multi-chamber container. Only after turning the cap can only a mixture of substances be removed via the removal channel.
35

The axial projection 16 is expediently designed so that

/ 7

it runs from the bottom of the inner container 5 * A centering aid 18 A for the axial projection 16 or inner container 5 consists of a funnel which opens into the beginning of the removal channel 18, 5

A sectional view according to section A-A' from Fig. 1 is shown in Fig. 2, but without a section through the inner container 5 or with a top view of the inner container 5. Fig. 2 particularly illustrates the projections 11, 12,

1Ö 13, 14 and the axial projection 16 with a polygonal profile 17. If the inner container 5 is rotated anti-clockwise using the cap 6, the two projections 11, 12 touch the underside of the projections 13, 14 in a first position. Due to the inclined position of the projections 11, 12, the further rotation process initiates a displacement of the inner container 5 in the axial direction downwards, so that after approximately a rotation of 90 degrees the inner container 5 is separated from the cap 6.

A sectional view according to section BB ¹ from Fig. 2 is shown in Fig. 3, but with an upper limit of the section AA ¹ from Fig. 1. This further makes it clear how the projections 11, 12 communicate with the underside plane 20 of the outer container projections 13, 14.

The upper planes 22, 23 of the projections 13 _and 14 represent an assembly aid, whereby the projections 11 , 12 are oriented along the planes 22, 23 when inserted into the multi-chamber container 1 in such a way that the projections 11, 12 can pass the projections 13, 14 unhindered. The upper planes 24, 25 of the projections 11, 12 are in contact with the lower planes 20, 21 of the projections 13, 14 during the separation process.

Fig. 4 shows a further embodiment of the inner container 5 ¹ with an axial projection 16, which serves as a

Pipe 26 is formed and connects the removal channel 18 in a liquid-tight manner with the outer container chamber 3. To aid assembly, the pipe 26 opening into the removal channel 18 is conical. Depending on the length of the pipe 26 into the outer container chamber 3, a maximum partial removal of the substance 27 located in the outer container chamber 3 can be limited.* This limiting state is shown in Fig. 4. Further removal of this substance 27 and the further second substance 28 can only take place in a mixed state, for which purpose the container is closed again with the closure 15 and the inner container 5 ¹ is released from the cap 6 by turning the cap 6. A homogeneous mixture of the two substances 27, 28 can be achieved by briefly shaking the multi-chamber container 1. In order to remove a mixture of substances, the closure 15 is then removed again.

Fig. 5 to 8 show differently designed outer container projections 13", 14 ¹ and 13'', 14*'. Fig. 5 and show cylindrically designed inner container projections 11', 12*. The projections 13', 14' have symmetrical wedge-shaped inclined planes 20', 21' on the underside. This allows the inner container 5'' to be separated by rotating the cap 6 in any direction. On the upper side, the projections 13', 14" have an inclined plane 22', 23', whereby the projections 11', 12' can slide along the upper inclined plane 22', 23' of the projections ^13' , 14' for the purpose of automatically overcoming the projections 13', 14' according to a storage position according to Fig. 5.

In contrast to the multi-chamber containers shown so far, the multi-chamber container according to Fig. 7 and 8 is equipped with an oval-shaped outer container 4. The projections 11'·, 12'' are oriented transversely to the axis of the multi-chamber container; the projections 13*·, 14'*, however,

Are provided on the top and bottom with inclined parallel planes 22", 23", and 13", 14" respectively. The projections 11", 12", 13", 14" conveniently communicate in such a way that with a rotation of the cap 6 by approximately 120 degrees the inner container 5" is separated from the cap 6.

A preferred embodiment of a multi-chamber container I" ¹ ' is shown in its individual parts in Figs. 9 to 18. Thus, in Fig. 9 in an axial section

1C shows an inner container 5"' through which an axially extending tube 26' runs. In the lower area of the inner container 5"', two diametrically opposed projections 11"', 12'" are arranged on the outside. From the inner base of the inner container 5' ", two diametrically opposed projections 16 A, 16 B run on the outside of the tube 26'. In the lower area of the inner container 5"', two diametrically opposed projections 11"', 12"' are arranged on the outside, which have the shape of a rhombus (see also Fig. 11!).

For better illustration, the inner container 5'" is shown in a plan view in Fig. 10.

A side view of the inner container 5'" rotated by 90 degrees according to Fig. 9 is shown in Fig. 11. In particular, the rhombus-shaped design of the projections 11'", 12'" is evident here. On the edge of the inner container 5'" there is a continuous ring 31 on the outside, which serves for a locking connection with the cap 6', 30

A view of the lower side of the inner container 5'" is shown in Fig. 12. It is clear that the projections 11'", 12"' have approximately the width that corresponds to the diameter of the inner container 5"'. 35

A further sealing ring 9' serves for a liquid-tight connection between the cap 6· and the inner container 5'". Between the sealing rings 9', 10' there is an interrupted locking ring 30 which ensures a secure connection between the cap 6' and the inner container 5 ^111. For a liquid-tight connection between the removal channel 18 and the axial projection 16 or the tube 26' of the inner container 5'", sealing rings 31 are provided in the lower area of the removal channel 18. In the lower area of the cap 6' there are knobs 32 on the inside for a locking connection 7 with the outer container 4 ¹¹ '.

A view rotated axially by 90 degrees is shown in Fig. 14. This shows particularly clearly the funnel-shaped recess 29 on the hollow cylindrical projection 19 of the centering aid 18 B. The narrower area of the recess 29 serves as a seat for the two projections 16 A, 16 B of the inner container 5 ¹¹¹ .

A view of the cap 6 from below is shown in Fig. 15, where the interrupted locking ring 30 is particularly clearly shown.

An outer container 4 ¹¹¹ corresponding to the inner container 5 ^IT1 and the cap 6 ¹ is shown in Figs. 16 to 18. The projections 13'·', 14· " are rhombus _- shaped in the form of bulges extending into the outer container 4·''.
