An evacuable container includes a first side wall having an interior surface and an exterior surface. The first side wall includes an aperture between the interior surface and the exterior surface. A second side wall has an interior surface and an exterior surface. The second side wall is connected to the first sidewall such that the interior surfaces of the first and second side walls form an interior of the container. A sheet has a first surface and a second surface. The first surface faces the exterior surface of the first side wall. The sheet is sealingly attached to the exterior surface of the first side wall so as to form a flow chamber between the first side wall and the sheet. The sheet includes (i) a plurality of flow channels disposed on the first surface, and (ii) an aperture between the first surface and the second surface. A check valve is disposed in fluid communication with the aperture in the sheet. An evacuation path can be formed from the interior of the container to an exterior of the container through the aperture in the first side wall, the flow chamber, the aperture in the sheet, and the check valve. |
