ABSTRACT:
A vacuum packing device for use with a resilient flexible container which has a resealable cover. A valve is releasably connectable to the cover through an aperture therein and is selectively openable and closable when the cover is engaged to permit withdrawal of air from the container and to prevent air from entering the container. A wire cage support is insertable in the container before engaging the cover to prevent the collapse of the container when air is withdrawn therefrom.
