More precisely, as illustrated, the ring 22 is intended to be placed in abutment on a body of the receptacle, here on the shoulder 20 of said tube head 2, around the neck 3, in the waiting position. It thus maintains a spacing between the cap 1 and the shoulder 20 when the cap 1 is screwed onto the neck 3 while waiting for the first use. The punch 14 then extends inside the neck 3, at a non-zero distance from the insert 8, thus preserving the lid from any cutting or perforation.
