Abstract
A container, such as a flask or a flexible tube, provided with a cap, the container including a side wall and a plastic head with a neck and a shoulder linking the neck to the side wall. The cap is provided with a circular cylindrical skirt on its inner surface with one or more first screwing means. The wall of the neck is substantially shaped like a prism where the cross-section is globally a polygon having a symmetry of order n about an axis A substantially parallel to the generatrix of the prism, n being an integer strictly greater than 1, and the neck is provided on its outer surface with n second screwing means, uniformly distributed about the axis A. The assembly of n second screwing means of the neck co-operates with the first screwing means of the cap.

A container provided with a cap, said container comprising a side wall and a plastic head with a neck and a shoulder connecting said neck to said side wall, said cap being provided with a circular cylindrical skirt provided on an inner surface thereof with at least one first screwing means, the neck having a substantially prism-shaped wall having a section which is globally a polygon which has n-order symmetry around an axis A, substantially parallel with a generating line of said prism-shaped wall, n being an integer strictly greater than 1;
- wherein said neck is provided on an outer surface thereof with n second screwing means regularly distributed around said axis A, all said n second screwing means on the neck cooperating with said first screwing means on the cap.
The head of a container, provided with a neck and a shoulder constructed and arranged to connect said neck to a side wall of said container, wherein a wall of said neck has substantially a shape of a prism having a section which is substantially a polygon with n-order symmetry around an axis A, substantially parallel to a generating line of said prism, n being an integer strictly greater than 1, and said neck is provided on an outer surface thereof with n second screwing means, regularly distributed around said axis A.
