Patent

CA 2407379

This invention is directed to an improved collapsible bag (10) having a spout (12) and one or more grooves (14) on the interior surface of a wall of the bag (10). The grooves (14), which are integral to a wall of the bag (10) rather than on a separate evacuation strip, are in liquid communication with the spout (12) and are sized such that the opposing wall of the bag (10) is not completely forced into the grooves (14) under the suction of conventional pumps which are used to withdraw the liquid from the bag (10). Thus, the grooves enable substantially complete withdrawal of the liquid from the bag (10) without the use of an evacuation strip. Additionally, the present invention may be used in any orientation and odes not require a slanted rack.
