<p>An apparatus for vacuum sealing plastic bags of the type disclosed comprises a hood (33) adapted to define a vacuum chamber (34) when it is moved to a closed position on a support surface (32). An elastomeric seal (39), circumventing the vacuum chamber, is adapted to engage and statically seal outer surfaces of a bag (21). The seal (35) 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 (20a) are provided for evacuating and heat sealing the bag. The hood (33a) can be pivotally mounted on a base (32a) 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 (77) for a container (78) whereby the container can be selectively evacuated.</p> |
