Abstract: A package and method for the packaging of contents at a reduced pressure which provides for improved protection of said materials from contamination. The method includes hermetically sealing a gas and vapor impermeable packaging containing both the material, object, and/or device and an adsorbent at elevated temperature. Subsequent cooling of the adsorbent results in the production of a partial vacuum within the packaging. Alternatively, if the packaging is evacuated prior to sealing by use of some mechanical device, the subsequent cooling of the adsorbent results in a further reduction of the interior pressure of the packaging. The improvement is provided by the presence of the cooled adsorbent in the packaging. Due to the presence of the cooled adsorbent within the packaging, the vacuum within the packaging is produced or increased and more readily maintained due to the adsorptive action of the adsorbent.

Abstract: It is an object of the present invention to provide a cooking apparatus which is suitable for an installation in a kitchen and cooks, bags and cools food without the use of a metallic clip. The cooking apparatus comprises a kettle for cooking food by heat, a bagging table for bagging the food cooked by the kettle, a carrying pump for carrying the food cooked by the kettle, a filling valve disposed on the bagging table and for filling the food carried by the carrying pump in a bag, a heat welding type sealer disposed on the bagging table and for heating and sealing an opening side end of the bag filled with the food by the filling valve, and a cooling device for cooling the bag sealed by the heat welding type sealer.
