A closure system for a can of the type presenting a tubular body which is inferiorly closed

Abstract

A closure system for a can of the type presenting a tubular body (10), with a circular or polygonal cross section, which is inferiorly closed and comprises: a peripheral side wall (11) provided with an upper edge (12); and a structural ring (13) internal to the tubular body (10) and which is hermetically united to the peripheral side wall (11) in order to define an upper opening (14) of the can and a seat (15) for the seating of a sealing element (20), the structural ring (13) being defined by a circumferential rib (16), formed by a recess in the peripheral side wall (11) which is axially spaced back in relation to the upper end (12) of the latter and projecting radially into the tubular body (10).
