Composite cap intended to be snapped on the glass ring of a bottle and then to serve as a stopper that can screwed and unscrewed as required, the glass ring being provided with at least one annular bead. It comprises a shell with a skirt provided with an internal annular bead; a first insert, disposed inside said shell, provided with an internal screw thread, characterized in that it also comprises a second insert having at least two roughly cylindrical portions; the first portion being provided on its external wall with a screw thread complementary to that of said first insert, the second portion being provided with axial immobilization means intended to cooperate with said annular bead and axial stop means, cooperating with said internal annular bead, so that the inserts secured together by screwing are trapped inside said shell. |

1. A composite cap adapted to be fixed to a glass ring of a bottle having a neck and then to serve as a stopper that can be screwed and unscrewed as required in order to close or release a dispensing orifice of said bottle, said glass ring being provided with at least one annular bead, said composite cap comprising:
a shell, with a substantially cylindrical skirt, provided with an internal annular bead; a first insert, disposed inside said shell, secured to said shell, comprising a skirt provided with an internal screw thread,wherein the composite cap also comprises a second insert, roughly in the form of a sleeve having at least two roughly cylindrical portions
the first portion being provided on its external wall with a screw thread complementary to that of said first insert, so that said first insert and said second insert are an assembly secured together by screwing, situated inside said shell; the second portion being provided with an axial immobilisation means adapted to cooperate with said annular bead on said glass ring and axial stop means, cooperating with said internal annular bead, so that said assembly secured together by screwing is trapped inside said shell; wherein said first insert comprises a head extending transversely to said skirt of the first insert, and wherein the composite cap also comprises an attached seal, placed inside the first insert and having a diameter such that the attached seal remains trapped between said head and the upper end of said first portion and wherein said first portion of the second insert has a height such that, when said composite cap is secured irreversibly to said glass ring, the top end of the first portion of the second insert is situated below the level of the top of the glass ring, so that, when said composite cap is placed on the glass ring, an annular abutment zone, close to the periphery of said attached seal, comes into contact with the top of the glass ring and, after irreversible securing of the composite cap on the neck of the bottle, said annular abutment zone is compressed between the head of the first insert and said top of the glass ring. |
