摘要

The sealing device consists of a disc (121) which can close the neck (101) of a receptacle and an inner capsule (122) which can be glued or sealed on the neck edge (113). A ring (124) with an inner thread (341) engages a neck outer thread (111). The ring is fitted with a stop (344) which extends from one edge in an axial direction (X-X') which can exert a pushing force (F3) on the disc in the direction in which the disk is separated relative to the neck. Independent claims are included for a receptacle and a method of producing the sealing device.
