ABSTRACT:
An apparatus for vacuum sealing plastic bags of the type disclosed in applicant's U.S. Pat. No. 4,756,422 comprises a hood adapted to define a vacuum chamber when it is moved to a closed position on a support surface. An elastomeric seal, circumventing the vacuum chamber, is adapted to engage and statically seal outer surfaces of a bag. The seal isolates an open end of the bag and the vacuum chamber from ambient and maintains such open end in communication with an evacuative chamber of the bag. A vacuum system and sealer are provided for evacuating and heat sealing the bag. The hood can be pivotally mounted on a base or can be used as separate, self-contained unit adapted for placement on a support surface defined on a counter top or the like. The apparatus is further adapted for connection to a unique vacuum sealing attachment for a container whereby the container can be selectively evacuated.
