Closure for openings in small containers - has insertable flexible ring with non-circular socket for closing body

摘要

The outer contour of the ring (6) matches the opening (4) in which it is inserted. A closing body (7) to be inserted into the ring has a circumferential outer groove (14) defined by a holder flange on one side and by a closing disc on the other one. The outer contour of the disc corresponds to the contour of the socket in the ring so that, after insertion into the ring, the closing body fits exactly in the socket through its closing disc. The closing body is rotatable in the ring, where it can be rotated from the release to the clamping position by altering the radial expansion or contact pressure of the ring. USE/ADVANTAGE - For porcelain, ceramic, or plastics piggy banks etc., with lazy mfr., reliable function, and easy fitting.
