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.

What is claimed is: 1. A container, comprising:a flexible, air-tight bag having an entrance opening for inserting an item to be stored into said bag;a releasably-closable seal across said entrance opening;a one-way valve assembly installed in a surface of the bag and forming a flow path from the inside of the bag, through a circular flange and to the outside of the bag, the valve having an outer portion with an exterior surface located outside the bag and further having a center with at least one exit hole sufficiently close to the center so a vacuum cleaner nozzle can be placed over the at least one exit hole, the exit hole having a side near the center and a side away from the center, the exterior surface having at least one ridge or at least one groove therein extending away from the center and having a portion located sufficiently close to the at least one groove or at least one ridge so that the nozzle abuts the ridge or overlaps the groove when the nozzle is placed over the at least one hole during use, wherein the exterior surface is located on an outer body portion which in turn is connected to an inner body portion that contains the circular flange; anda flexible diaphragm resiliently urged against an edge of the circular flange to permit and prevent air flow through that circular flange depending on the configuration of the flexible diaphragm, the diaphragm having at least one tab thereon located to bend in the direction of a suction force applied to the at least one exit hole to change the configuration of the flexible diaphragm and allow air flow through the circular flange from inside the container, the at least one tab being on an outer periphery of the diaphragm which outer periphery is non-circular, the diaphragm having a centrally located post extending therefrom, the post having an end fastened to the valve assembly and not moving relative to the circular flange.
