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.

An apparatus for vacuum sealing a plastic bag having overlying first and second panels defining an evacuative chamber and overlying heat sealable panel portions terminating at an open end of said bag communicating with said evacuative chamber, said apparatus comprising a base defining an upper support surface adapted to receive the open end and sealable panel portions of said bag thereon, a hood mounted on said base and movable to a closed position to position a frontal side thereof over the open end and sealable panel portions of said bag, said hood and base defining a vacuum chamber means therebetween having a width extending from a frontal side of said apparatus that is sized to only receive the open end of said bag in exposed relationship therein and to position remaining portions of said bag exteriorly of said apparatus, static seal means circumventing said vacuum chamber means and disposed between said base and said hood for directly engaging outer surfaces of the sealable panel portions of said bag in response to movement of said hood to its closed position to form a static seal isolating only the open end of said bag and said vacuum chamber means from ambient and to maintain the open end of said bag in communication with the evacuative chamber thereof, evacuation means communicating with said vacuum chamber means for selectively evacuating said vacuum chamber means and the evacuative chamber of said bag, and heat sealing means, including a heating element mounted forwardly on one of said base and said hood, for selectively forming an air-tight heat seal across the sealable panel portions of said bag to maintain said vacuum within the evacuative chamber of said bag.
