Abstract

In an hermetically sealed fresh-keeping container for organic substances, in particular foodstuffs, with a dimensionally stable bottom part that incorporates a support surface for the goods that are to be kept fresh, a similarly dimensioned and stable upper part that is mounted on the lower part, above the support surface, so as to be removable. The hood forms a useable space, and a vacuum pump system removes the air within the useable space. The useable space is also delimited by an airproof foil, the edge of which is releasably connected with a wall of the container. A suction opening of the vacuum system is incorporated in this wall.
