Abstract

A plastic container (8) has a lid (14) sealed with O-ring (16) and has a hole (20) in lid (14) over which is fitted a cup-shaped valve (28) held loosely in position by bolt (22) which passes through hole (20) and is secured by spaced-apart locknut (24). A vacuum source (33) is connected by hose (46) to rubber cup (38) which can be placed over cup-shaped valve (28) to evacuate air from container (8), after which cup (38) is removed by squeezing with hand, causing cup-valve (28) to seal against flat surface of lid (14) by atmospheric pressure. Container (8) is then placed under refrigeration for long term preservation of its contents.
