ABSTRACT:
A container and sealing closure therefor, includes a container body part having an access opening and includes a continuous peripheral wall surrounding the access opening, and a closure part. The wall of the body part has a peripherally extending continuous sealing edge portion at its upper outer surface, the edge portion being coextensive with the wall. The closure part has a resilient skirt portion. The sealing edge portion of the wall of the container part has a sharp apex forming an included angle of substantially 90 degrees. The skirt portion of the closure part is adapted to mate in spaced relation, with the peripheral wall of the container part and has an inner surface which extends obliquely with respect to the peripheral wall of the body part and which is adapted to engage the apex. There are provided coengaging structural elements on the container body and closure parts, holding the resilient skirt portion of the closure part forcibly against the apex as the closure part is advanced against the container body part to a sealing, closed position thereon.
