A package is disclosed for containing a commestible and includes an integrally formed plastic base member and an integrally formed plastic top member. The base member includes a centrally disposed commestible receptical defined by a commestible supporting bottom portion and side wall portions extending substantially perpendicularly therefrom, with the side wall portions being bounded by an upwardly projecting engagement lip. The side wall portions have on oppositely disposed sides side wall peak portions having a greater height, and normally thereto side wall valley areas having a lesser height. Extending substantially horizontally from the lip is a lip re-enforcement flange. The integrally formed top member includes a centrally disposed commestible containing portion bounded by structures which matingly engage with those of the base member to enclose the commestible. In preferred embodiments, the base member bottom portion includes a plurality of congruent corrugations, which may further include a radially disposed tacking corrugation for urging the base member bottom portion upwardly in a spring-like fashion to hold the commestible into a substantially snug fit with the planar portion of the top member. The tacking corrugation may include an evacuating surface for insertion of an evacuation needle for supplying a vacuum to the sealed package.
