ABSTRACT:
A reusable resiliently restorable flexible sheet plastic closure is applied to a comestible-storing rimmed container. The closure has a crown and a skirt which is attached to and downwardly dependent from the crown. The crown and skirt are attached to one another by a generously rounded section. Positioned circumferentially around the free edge of the skirt is a retroverted lip which extends under the rim of the container for tightly locking the closure to the container. On the lower end of the skirt is a pair of diametrically opposed radially extending pull tabs in one-piece with and joined to the skirt by a generally S-shaped section. The pull tabs are capable of diametrically distorting the closure when pulled radially outwardly by a user to thereby unlock the closure by radially extending the retroverted lip such that it clears the container rim. Thus removal of the closure from the container occurs without destroying the integrity of either the retroverted lip, the closure or the container.
The above-described closure and container, when used in combination, provide a method for repeatedly storing comestibles using the same closure and container due to the fact that said closure may be integrally removed from said container and reapplied in its unimpaired state thereto when so desired.
