Safety closure for containers with plastic lids

The invention relates to a safety closure for

Containers with plastic lids that allow access to

The integrity of the container contents can be easily verified.

A large number of plastic containers with a lid that encompasses the entire circumference of the container are known from the prior art. For example, EP 02 87 980 discloses a plastic bucket with an associated snap-in lid, in which the bucket and the lid are designed at their edges in such a way that the lid seals securely and snaps into place. GB-PS 14 89 515 discloses another solution, according to which a container with a plastic lid is described. The wall of the container has an upper sealing edge for supporting and sealing the lid and is provided in its upper part with a receiving part that surrounds the sealing edge at a distance and with an engagement recess for gripping under the retaining fold on the lid. However, these solutions cannot prove that the contents of the container remain intact after the lid has been opened without authorization.

A container with a plastic lid is described in DE-PS 41 38 879, in which the grip under the lid is made easier by means of a grip recess and the grip recess is also designed as a pouring spout in the lower part. The grip recess is covered by a tear-off panel which is connected to the pulled-down part of the supporting edge by means of webs formed with several predetermined breaking points. The container can only be opened after the panel has been removed beforehand, so that unauthorized opening can easily be detected.

Another sealed container with an inviolable closure, opening device and retaining bracket is described in DE-OS 31 91 794. The closure piece or the inviolable closure consists of a ring and an edge band or band iron with certain weak zones, so that when the

·

The weak zones can be broken by the ring, whereby access to the interior of the container is impossible without destroying the closure. "The disadvantage of both of the solutions mentioned is the manufacturing effort for such safety closures when producing the plastic containers.

The invention is based on the object of developing a simple safety closure made of plastic, which can be easily molded during the production of the plastic containers and requires minimal material expenditure.

This task is solved with the constructive features of the protection claim.

The advantage of the invention is that with this simply designed safety closure, proof of the integrity of the contents can be easily provided by forcibly tearing off the container when it is opened by unauthorized persons.

Example

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows

Fig. 1 the safety closure molded onto the container,

Fig. 2 the pull tab formed on the edge of the lid.

The safety closure 3 with its two downward-pointing legs 4 is molded onto the container 1, for example in the area of a recess 2, while a pull-off tab 7 is arranged on the edge of the lid 6, which is provided with an opening 5.

After filling the container 1 and putting on the lid 6, the safety closure 3 is pushed through the opening 5 so that it rests on the container edge 1 or in the recess 2 by means of its two downward-facing legs 4. When opening the container 1 by means of the pull-off tab 7 arranged on the lid edge 6, the safety closure is irreparably torn off so that unauthorized opening can be proven.
