PLUG WITH SEALING, METHOD FOR PRODUCING SUCH A PLUG AND ASSEMBLY COMPRISING A CONTAINER AND SAID PLUG WITH SEALING

摘要

P Plastic plug, with screw, comprising an internal annular projection (19) allowing the maintenance of an attached seal (3) in the shouldered and floating position in a space (29) formed between the internal face ( 20) of the transverse wall (12) of the plug and the upper face (28) of said seal (3). When the seal (3) is put in place, the latter is force-fitted for the passage of the projection (19). The seal (3) is deformed, when the plug is placed on the neck of the container, the bead (26) of the seal (3) being crushed by the free end of the neck (4) of the container.
