摘要：

COLLAPSIBLE CONTAINER AND CHECK VALVE The collapsible bag-like container (20) includes a flat profile collapsible check valve (21) at the fill end (32) of the container. A fused line of connection (60) anchors the check valve to the container (20), with a tab (56) inserted in the open ended fill passage (54) of the check valve. The tab weakens the seal formed by the line of connection (60) across the bag and check valve and assist the user in opening the fill passage.
