Claim:
A hermetically sealable foodstuffs preserving container with internal partial vacuum making facilities for foodstuffs preserving, comprising: a base body for containing and preserving foodstuffs and having an edge with a free border; a flexible lid hermetically connectable with said base body, said lid having, at least in a peripheral region thereof, an elastically flexible portion for expelling air from said base body upon flexing of said lid; a circumferential wing that acts as a grip element for lifting an edge part of the flexible portion during a compression of a central portion of the lid for expelling air from said base body for producing in the container an internal partial vacuum; a groove provided at said flexible portion of the lid, peripherally thereto so as to be open toward the edge of said base body; and at least one through hole arranged at said edge of the base body, at a distance below a top free border of said edge that is shorter than a depth of said groove; such that said lid is arranged on said base body so as to mate hermetically, during said compression of said central portion of the lid for expelling air from said base body for producing in the container the internal partial vacuum, with said edge in a region thereof that lies above said at least one through hole while simultaneously allowing air to escape from inside said base body outwardly through said at least one through hole to form the partial vacuum inside said container.
