Container closure for two-material packaging

The innovation relates to a container lock for Zweistoffverpaokungen, which consists of an inner plastic container and consist of an outer metal container.

In the case of the known container closures of this type, two-material packaging is the inner plastic container opposite the outer metal container at the container opening of the upper floor of the metal container through which the spout of the container closure of the inner plastic container is passed, not sealed liquid-tight, so that the contents of the inner plastic container, if this becomes leaky at one point of its wall during transport, through the pouring nozzle opening the outer metal container can flow out. Due to the escaping liquid, which is often corrosive or is flammable, the! transport vehicle and the personnel operating the transport are at risk.

To avoid this risk it is proposed according to the innovation, the container closure of the inner plastic container, the pouring spout through a corresponding opening of the upper one The bottom of the outer metal container reaches through, with a

to provide flexible sealing ring, which clamps around the pouring spout with appropriate bias and the clamped by the screw ring of the pouring spout of the container closure between the tops of both containers will. This also creates a liquid-tight seal for the opening in the upper base of the outer metal container achieved. To improve the sealing effect of this sealing ring, according to a further proposal, the edge of the opening is to be hired of the outer metal container flanged inwards, whereby the edge is in the flexible sealing ring when ]? es1g? annen pushes through the screw ring.

The figure shows a two-substance container in a longitudinal section through the container closure.
The following are designated:

With 1: the inner plastic container in general, with 2: its upper base with pouring spout 3, which is provided with external thread 4, with 5: its screw cap, with 6: its inserted sealing ring, with 7: the screw ring on the external thread 4 of the semolina nozzle 3 , with 8: the outer container in general, with 9: its upper base, with 10: the inwardly beaded edge _{3 of} the passage opening for the pouring spout and with 11: the outer sealing ring of the container closure, which is between the upper bases 2 and 9 of the inner and outer container 1 and 8 is clamped.
