ABSTRACT:
A recloseable lid construction for a paperboard container. The lid is a separate sheet and carries two radially spaced microcuts near its outer periphery. The radially outermost peripheral portion of the lid is bent upwardly and is sandwiched by an inwardly folded strip, the latter integral with the upper vertical side wall of the container. The inwardly folded strip carries a cutout which is aligned with an upwardly extending opening tab integral with the lid. Upon opening, the tab is pulled and separated from the radially outermost lid portion, and the two microcuts act to rip the paperboard and form a ledge around the dispensing opening. The lower portion of the inwardly folded strip is radially inwardly flared to define a snap reclosure. At least one of the microcuts in is filled and caulked with a barrier layer material, the barrier layer material also, preferably, covering the entire lid surface having the caulked microcut.
