CAP FOR THE NECK OF A CONTAINER

摘要

The invention relates to a cap (1) including a tubular skirt (20) which includes, in series along the axis (X-X) of said skirt, a first portion (40), on the inside of which a removable means (41) for attachment to the outer surface of a neck (2) of a container is provided, and a second skirt portion (50) comprising: a first axial end (51), which connects the rest of the second skirt portion to the first skirt portion, and on the inside of which at least one surface (54A, 57A) for axially abutting the free end (4) of the container neck is provided; a second axial end (53), axially opposite the first end, which is transversely closed off by a bottom wall (10) of the cap; and an intermediate portion (52) which extends axially between the first and second ends, from which ribs (55, 57) radially project substantially parallel to the axis (X-X), said ribs being distributed along a direction peripheral to said axis, and which, in a half-sectional view of the skirt, have, outside of said ribs, a radial dimension which is strictly less than the radial distance between the outer cylindrical surface of the first skirt portion and the inner radial end of the abutment surface(s).
