CONTAINER WITH CAVITY BASE

摘要

A container base (16) includes a standing ring (20) at an end of a sidewall (12) of a container (10); and a closed arcuate end wall (26) extending from the standing ring and projecting inwardly relative to the end of the sidewall. The inwardly projecting end wall extends entirely within the sidewall and an imaginary plane extending through said standing ring. An object (34) can be placed in the cavity defined by the inwardly projecting end wall and the imaginary plane extending through said standing ring. A sheet-like seal (36) can be placed on the base at the standing ring to extend over the end wall and retain the object within the cavity.
