leather-bearing disc by a collar with an inwardly protruding collar Rifle is held *.

In the invention, the connection between such a disc and a Can with closed rim by pouring in the disc material or by gluing together two discs on both sides of the .inwardly protruding collar made.

Celluloid is particularly suitable for both of the above-mentioned production methods, as is otherwise offers many advantages to this arrangement, such as: B. Adaptability, plasticity, shock resistance, which enables a firm connection, ease of working, great adhesiveness in the loosened state, whereby a tough, resilient adhesive bond that is not sensitive to moisture dung is achieved.

An embodiment of the subject matter of the invention is shown in the drawing.
