Closing cap for a container and relative making method

Abstract

A closing cap for a container that includes a lateral wall extending around an axis and a transversal wall positioned at one end of the lateral wall, an intended separating line being provided on the lateral wall to define a retaining ring, which is configured to remain anchored to a neck of the container, and a closing element removably engageable with the neck, so as to open or close the container. The cap includes a joining zone in which the retaining ring and the closing element are joined. The intended separating line is positioned in a strip of the lateral wall having an enlarged first part, whose thickness is increased relative to the thickness of a remaining second part; and the intended separating line is made by means of an incision extending for 360° which partly cuts into the enlarged first part and passes through an entire thickness of the lateral wall in the remaining second part in such a way that the joining zone is defined in the enlarged first part.
