  • Patent number: 4903459
    Abstract: A method and apparatus for discharging vacuum packaged goods from a vacuum packaging apparatus. While a chamber held in contact with the upper surface of a table and defining an airtight space therein is in movement integrally with the table for one round of travel along an endless track, the chamber is lifted from the table for a given period of time for supply into the chamber of goods to be packaged as contained in a bag. When the chamber is again brought in contact with the table, a vacuum atmosphere is created in the chamber so that the mouth of the bag is sealed, vacuum packaged goods being thus obtained. A table portion within the chamber is formed with an open/close type drop opening which is sealed by a cover plate. The to-be-packaged goods contained in a bag, as well as vacuum packaged goods which are sealed at the mouth of the bag, are loaded on the cover plate.
