Closure Arrangement for Cans

A closure arrangement for cans of the type which comprises:

• a body portion inferiorly closed;
• a neck portion, presenting a reduced contour and an upper end edge, which incorporates an outer peripheral projection and defines the contour of an upper opening;
• a transition portion, joining the body portion and the neck portion;
• and a lid having a panel portion which incorporates a peripheral tubular portion to be fitted, with interference, into said upper opening, and having an upper edge carrying an outer circumferential rib, the arrangement being characterized in that the outer circumferential rib presents a semi-tubular shape inferiorly opened and having:
• a radially inner edge which is joined to the upper edge of the peripheral tubular portion of the lid, by an annular step which projects outwards from said peripheral tubular portion;
• and a radially outer edge, spaced from the radially inner edge, the outer circumferential rib carrying, in its interior, an annular gasket to be seated and pressed against the outer peripheral projection of the neck portion upon the fitting of the lid into the upper opening (A) and the seating of the annular step on the outer peripheral projection of the neck portion.
