20090232423 | VALVE FOR VACUUM STORAGE BAG - A flexible, air-tight storage bag has an entrance opening for inserting an item to be stored into said bag with a releasably-closable seal across said entrance opening. A one-way valve assembly is installed in a surface of the bag and in fluid communication with the inside of the bag to allow air inside the bag to exit the bag. The valve has an outer portion with a conical or curved exterior surface having an apex and a plurality of exit holes adjacent the apex so a vacuum cleaner nozzle can be placed over the exit holes. The outer portion has a conical or curved surface with at least one ridge thereon or groove therein extending away from the apex and beyond the exit holes to reduce the suction. A circular flange in the valve is located so air passes through the flange. A flexible diaphragm is placed in the circular flange so the diaphragm abuts an edge of the flange to vary the flow of air. The diaphragm has a non-symmetric flange formed by outwardly extending tabs so that air pressure on the tabs deforms the diaphragm and breaks the seal between the diaphragm and the flange to allow air flow through the valve. | 09-17-2009 |
