ABSTRACT:
A two-piece closure with a skirt portion surmounted by an upstanding flange having integral extended parts at least in the shape of an inverted U and a disc portion having an at least upward projection at the disc's periphery with this projection substantially confined between the integral extended parts of the upstanding flange portion. The upstanding flange portion confining the projection is swaged with an imprinted crimp design on its surfaces so that it is offset radially inwardly from the skirt portion to form a shoulder sufficiently wide to accomodate a duplicate skirt portion stacked thereon. In a preferred embodiment the integral extended part of the upstanding flange has two 180.degree. folds and the projection at the disc's periphery is extended in the shape of an inverted U with the upstanding flange and projection interfolded to interlock.
