ABSTRACT:
It is well known that food to be frozen, if placed in an evacuated container before it is frozen, will better retain the flavor and freshness of the food. However, there is no apparatus available and known to the applicant which permits evacuation of a container for food to be frozen in the home. The instant invention overcomes this deficiency by providing a system for evacuating flexible containers for food to be frozen in the home. The system includes a hollow retainer member adapted to receive the open end of the container, and a cap member which is adapted to fit over the outside surface of the retainer in airtight engagement therewith. A flexible tube extends downwardly through the bottom end of the cap member and upwardly above the cap member, and means are provided on the upward part of the tube for opening and closing the passage in the tube. In operation, the open end of the container is inserted through the hollow retainer and draped over the top end of the retainer, and the cap is mounted over the top surface of the retainer and the open end of the container and in airtight engagement therewith so that the tube passage is in airtight communication with the interior of the container. Air is withdrawn from the container through the tube, and the means on the upward part of the tube is then closed to close the tube passage.
