Gusseted pouch

Abstract

A pouch is defined by first and second panels of a flexible laminate. The first and second panels each have an outside first face, an inside first face and a barrier layer disposed between the outside first face and the inside first face. The pouch has first and second gusset portions each having an inside face, a gusset outside face and a barrier layer disposed between the inside face and the outside face. A bottom portion of the inside face of the first panel is bonded to a bottom portion of the inside face of the first gusset. A bottom portion of the inside face of the second panel is bonded to a bottom portion of the inside face of the second gusset. A top portion of the inside face of the first panel is bonded to a top portion of the inside face of the second panel.

1 . A pouch comprising: 
 a first panel having an outside first face, an inside first face and a barrier layer disposed between the outside first face and the inside first face;    a second panel having an outside second face, an inside second face and a barrier layer disposed between the outside second face and the inside second face;    a portion of the periphery of the inside faces of the first and second panels bounded together to define a pouch cavity;    a first gusset portion having a first gusset inside face, a first gusset outside face and a barrier layer disposed between the first gusset inside face and the first gusset outside face; and    a second gusset portion having a second gusset inside face, a second gusset outside face and a barrier layer disposed between the second gusset inside face and the second gusset outside face;    a bottom portion of the inside first face is bonded to a bottom portion of the first gusset inside face, a bottom portion of the inside second face is bonded to a bottom portion of the second gusset inside face, and a top portion of the inside first face is bonded to a top portion of the inside second face, the first and second panels and the first and second gusset portions being bounded together with the first and second panels to form the pouch cavity.    
   
   
       2 . The pouch of  claim 1 , wherein a sealant layer disposed on each of the inside and outside faces of each of the first and second gusset portions.  
   
   
       3 . The pouch of  claim 2 , wherein the first and second gusset portions further comprising a strength layer.  
   
   
       4 . The pouch of  claim 1 , wherein each of the inside first face and the inside second face are coated with a sealant layer.  
   
   
       5 . The pouch of  claim 4 , wherein the sealant layer is polypropylene.  
   
   
       6 . The pouch of  claim 4 , wherein the sealant layer is polyethylene.  
   
   
       7 . The pouch of  claim 1 , wherein the barrier layer is aluminum oxide.  
   
   
       8 . The pouch of  claim 1 , wherein the barrier layer is silicone oxide.  
   
   
       9 . A collapsible container comprising: 
 a first panel having a sealing side and a non-sealing side;    a second panel having a sealing side and a non-sealing side; and    third and fourth panels, each having two sealing sides and a barrier layer disposed between the two sealing sides,    at least a portion of the sealing side of the first panel is bonded to at least a portion of the sealing side of the second panel and at least a portion of a first sealing side of the third panel,    at least a portion of a second sealing side of the third panel is bonded to a portion of a first sealing side of the fourth panel; and    at least a portion of the sealing side of the fourth panel is bonded to at least a portion of the sealing side of the first panel and at least a portion of a second sealing side of the fourth panel.    
   
   
       10 . The container of  claim 9 , each of the first and second panels further comprising a barrier layer.  
   
   
       11 . The container of  claim 9 , each of the third and fourth panels further comprising a strength layer between the first sealing side and the second sealing side.
