Packaging container with tube in tube

The innovation relates to a packaging container consisting of a larger tube and a concentric tube arranged smaller tube, as well as a tube closure, the tubes via an intermediate part under Formation of passage openings in the neck area are interconnected.

Such packaging containers have long been part of the state of the art and are, for example, from GB-PS 209 920, the US-PS 32 17 931 and DE-OS 15 86 446 become known. They are required when two different filling goods must be kept separate until use, but then removed at the same time and in most cases should be mixed well when taken out. These requirements lead to significant problems in the design Design of the removal opening. On the one hand, there must be an absolutely reliable separation of the two Filling goods must be taken care of at least until they are used for the first time; on the other hand, proper mixing must be ensured be guaranteed and ultimately the

packing container also resealable in this way be that the two different filling goods continue to be kept essentially separate. With the relevant packaging containers that have become known up to now, these requirements could not be met are met satisfactorily in all points.

There is thus the task of creating a packaging container of the type mentioned in which two In any case, filling goods to be mixed during use are kept absolutely securely separated until they are removed for the first time can be, at the same time must be ensured during removal for a good mixing and a Reclosing with good separation of the two filling goods is possible.

To solve this problem it is proposed according to the innovation, that the inner tube closes its outlet opening until it is used for the first time Membrane has that placed on the neck of the outer tube, a mixing chamber with an axially displaceable insert is and that the mixing chamber is closed with a screw cap which has a central on its top Has a pin and a second screw thread, by unscrewing the screw cap in the reverse position of use the insert is axially displaceable through the pin until the membrane is pierced. It will the insert is expediently cylindrical and has a point opposite the membrane and on the outside screw-like passage channels. The inner tube is preferably made of aluminum or an aluminum alloy, while the outer tube is made of Laminate material can exist.

In the case of a packaging container designed according to the new design, all of the requirements can be met without any problems to be met. The membrane provided on the inner tube prevents it from happening for the first time Use reliable the transfer of the filling goods into the respective other filling space. The mixing chamber with insert ensures perfect mixing of the two filling goods during removal and the screw cap In connection with the insert, it allows the piercing of the inner tube that closes off in a simple manner Membrane. The screw cap can be screwed on in the normal position of use and then closes the outlet opening of the mixing chamber. A better separation of the two filling goods after the first use, can be achieved by screwing on the screw cap in the reverse position of use, | the insert being pushed into the outlet opening of the inner tube and the exchange cross-section between .den two filling chambers is reduced to a minimum. Further details are available at the in Figure 1 illustrated embodiment explained in more detail.

Figure 1 shows a packaging container according to the innovation in longitudinal section. The smaller, inner tube 2 is with their neck inserted into the larger, outer tube 1 and via an intermediate part 13 with the formation of passage openings 14 firmly connected to this. The inner tube has an integrally molded membrane 7, which | Exit opening 6 closes. A mixing chamber 3 is screwed onto the neck 8 of the outer tube 1, which contains an axially displaceable insert 4 and is closed with a screw cap 5. The latter owns on its top a central pin 9 and a second screw thread 10, so / that it is also reversed

the mixing chamber 3 can be screwed on. The insert 4 has a tip 11 opposite the membrane 7 and has passage channels 12 running in a screw-like manner on its cylindrical outer surface.

When the packaging container is used for the first time, as mentioned, the screw cap 5 is screwed on in the reverse position of use, the insert 4 until it is pierced the membrane 7 is displaced axially. The screw cap 5 is then removed and pressed on the packaging container at the same time that in the inner tube 2 and in the space between the inner tube 2 and the filling material contained in the outer tube 1 is pressed out. In the mixing chamber 3, both products are filled with one another mixed so that the desired mixed product is obtained at the outlet opening.
