Storage container with vacuum

Abstract

A device comprising a first unidirectional flow valve not substantially in contact with ambient air, a second unidirectional flow valve whose air-flows terminate in ambient air and an elastically resilient chamber coupling the first unidirectional flow valve to the second unidirectional flow valve to permit air-flow from the first unidirectional flow valve to the ambient. Intermittent application of pressure to the chamber moves air from the first unidirectional flow valve to the second unidirectional flow valve.

         3 . The device of  claim 1 , wherein intermittent application of pressure to said elastically resilient wall expels air from said second unidirectional flow valve. 
     
     
         4 . The device of  claim 1 , wherein intermittent application of pressure to said elastically resilient wall moves air from said substantially air-tight container and expels said air from said second unidirectional flow valve. 
     
     
         5 . The device of  claim 1 , wherein said elastically resilient wall is coupled to a portion of said first unidirectional flow valve external to said air tight container. 
     
     
         6 . The device of  claim 1 , wherein said elastically resilient wall is integrated with said substantially air-tight container. 
     
     
         7 . The device of  claim 6 , wherein said elastically resilient wall is integrated with an external surface of said substantially air-tight container. 
     
     
         8 . The device of  claim 6 , wherein said elastically resilient wall is integrated with an internal surface of said substantially air-tight container. 
     
     
         9 . The device of  claim 1 , wherein said elastically resilient wall comprises material selected from the group consisting of rubbers, plastics and shape memory plastics. 
     
     
         10 . The device of  claim 1 , wherein said container is a food storage bag.

         21 . An improved device for creating flow out of a container having a unidirectional flow valve coupled to a substantially air-tight container, wherein the improvement comprises a secondary unidirectional flow valve coupled to an elastically resilient wall external of said container, said wall configured to completely circumscribe flow from said unidirectional flow valve to said secondary unidirectional flow valve.

 activating a first unidirectional flow valve coupled to said container wherein fluid from said container substantially travels to an elastically resilient wall external of said container comprising a second unidirectional flow valve; and,   activating said second unidirectional flow valve, wherein fluid substantially exits out from within said wall.   
     
     
         26 . The method of  claim 25 , further comprising intermittently applying pressure to said elastically resilient wall to substantially remove all fluid in said container.
