System to remove air from a bag

Abstract

This patent discloses a system to remove air from a bag. The bag may include a first sidewall and a second sidewall attached to the first sidewall at a first side, a second side, and a bottom. The first sidewall and the second sidewall may meet to form an opening and to form an interior. A valve may be positioned in the interior of the first sidewall and the second sidewall to form in the interior a first compartment having air and a second compartment. The valve may control an exchange of air between the first chamber and the second chamber. A foam sponge may be positioned in the second compartment. The foam sponge may draw air from the first chamber into the second chamber when the valve is open and the foam expands.

1 . A system to remove air from a bag, the bag comprising:
 a first sidewall;   a second sidewall attached to the first sidewall at a first side, a second side, and a bottom, where the first sidewall and the second sidewall meet to form an opening and to form an interior;   a valve positioned in the interior of the first sidewall and the second sidewall to form in the interior a first compartment having air and a second compartment, where the valve is configured to control an exchange of air between the first chamber and the second chamber; and   a foam sponge positioned in the second compartment, where the foam sponge is configured to draw air from the first chamber into the second chamber when the valve is open and the foam expands.   
   
   
       2 . The bag of  claim 1 , where the foam sponge is configured to hold the air in the second chamber and the valve is configured to prevent the air from returning to the first chamber. 
   
   
       3 . The bag of  claim 1 , where the bag is advertised as at least one of a storage bag, a freezer bag, a sandwich bag, and a snack bag. 
   
   
       4 . The bag of  claim 1 , where the foam sponge is in a compressed state. 
   
   
       5 . The bag of  claim 1 , where a pressure within the second chamber is less than pressure outside of and adjacent to the second chamber. 
   
   
       4 . The bag of  claim 1 , where the second chamber forms a second chamber first sidewall and a second chamber second sidewall and where the foam sponge is configured to expand outward to press against the second chamber second sidewall and second chamber second sidewall. 
   
   
       5 . The bag of  claim 1 , where the valve is a pop valve. 
   
   
       6 . The bag of  claim 5 , where the pop valve includes an air flow path, a one way valve, a snap valve, and a heat seal area. 
   
   
       7 . The bag of  claim 6 , where the snap valve is positioned within the heat seal area and the one way valve is positioned on top of the heat seal area in line with the air flow path. 
   
   
       8 . The bag of  claim 7 , where the air flow path includes hard pieces that taper into supple ends, where the supple ends are configured to permit air to flow in a first direction but prevent air flow in a direction opposite to the first direction. 
   
   
       9 . The bag of  claim 1 , where the valve is a lift valve, where the lift valve is configured to lift the first sidewall and second sidewall away from one another to aid in drawing air from the first chamber into the second chamber. 
   
   
       10 . The bag of  claim 9 , where the lift valve includes a first gap, a second gap, and a channel positioned between the first gap and the second gap, where the lift valve further includes a first flap having a first flap first end and first flap second end and includes a second flap having a second flap first end and a second flap second end. 
   
   
       11 . The bag of  claim 10 , where the first flap first end is attached to the first sidewall at a location within the lift valve and exterior to the channel, where the second flap first end is attached to the second sidewall at a location within the lift valve and exterior to the channel. 
   
   
       12 . The bag of  claim 1 , where the foam sponge is impregnated with an antibacterial agent to minimize bacteria growth. 
   
   
       13 . The bag of  claim 1 , where the valve is a first valve, the bag further comprising:
 a second valve between the first valve and the bottom, where the second valve is configured to control an exchange of air between the second chamber and an exterior to the second chamber.   
   
   
       14 . The bag of  claim 1 , further comprising:
 a first zipper seal between the valve and the top and a second zipper seal between the valve and the bottom.
