Cap for a container neck

摘要

A cap for a container neck includes a tubular skirt defining a central axis. The skirt includes an internal first skirt part, means for removably fixing the first skirt part to an exterior surface of the container neck, and a second skirt part. The second skirt part includes a first axial end connecting the second skirt part to the first skirt part, internally having at least one surface adapted to abut a free end of the container neck. The second skirt part also includes a second axial end opposite the first end, and an intermediate part extending between the first and second ends. Ribs project radially from the intermediate part in a direction substantially parallel to the axis. A radial dimension of the intermediate part is less than a radial distance between the exterior cylindrical surface of the first skirt part and the interior radial end of the abutment surface.

1. A cap for a container neck, comprising:
a tubular skirt having a central axis and including:
a first skirt section extending along the central axis and having threads for removably fixing the first skirt section to an exterior surface of the container neck, anda second skirt section including:
a first axial end having at least one abutment surface adapted to abut axially against an end of the container neck when the first skirt section is removably fixed to the container neck;a second axial end opposite the first axial end and connected to an end wall of the cap; andan intermediate section extending axially between the first and second axial ends, wherein a plurality of ribs project radially from the intermediate section towards the central axis and extend lengthwise substantially parallel to the central axis, wherein the plurality of ribs are distributed around the central axis, and wherein a radial thickness of the intermediate section is less than a radial distance between an exterior cylindrical surface of the first skirt section and an interior radial end of the at least one abutment surface, wherein each of the plurality of ribs includes:
an exterior radial end connected to an interior cylindrical surface of the intermediate section;an interior radial end radially opposite the exterior radial end;a first axial end connected to the end wall of the cap; anda second axial end having a lower surface, wherein the at least one abutment surface corresponds to the lower surface of at least one of the plurality of ribs.
