Verschluß für einen Sammelbehälter

摘要

The collection container (1) has a lid designed as a cylindrical stopper (3) and is guided axially movable in a corresponding cylindrical bore of the collection container and is sealed. The stopper is fixed across a safety ring (9) in the opening direction. The safety ring is protected against loosening by a blocking step provided at the stopper, lying at the inner diameter of the safety ring. The safety ring is inserted in a ring slot (10) of the bore (13), and a ring shaped end surface (7a) covers the outer side (7) of the stopper, and is limited inwards by the blocking step (8).
