Abstract: A hermetically sealable container with internal partial vacuum making facilities, comprising a base body with which a lid is hermetically associable, the lid having, at least in its peripheral region, an elastically flexible portion that has a groove arranged peripherally and open toward the edge of the base body. On the edge of the base body, at least one through hole is provided, arranged at a distance from the free border of the edge of the base body that is shorter than the depth of the groove.

Abstract: A method for the injection-molding of products made of at least two different materials, consisting, in a first step, in injecting into a mold a first material in an amount that corresponds to the lining of only a surface portion of the mold and, in a second step, in injecting at least one second material in order to lay at the inner portion of the mold lined by the first material and the remaining surface portion of the mold.

Abstract: A food container, particularly a hermetic container for preserving foods in refrigerators and freezers and for thawing in a microwave oven, comprising a base body with which a lid can be associated hermetically, the lid forming a groove that is open toward the edge of the base body. The lid has a substantially rigid central portion with which a substantially elastic peripheral portion that forms the groove is associated. The central portion reaches, in a radial direction, no further than the region delimited by the edge.
