Pouch with peelable seal for beverages

Abstract

Packaging containers for liquids, such as beverages, comprise: at least one sidewall comprising an edge seal and a frangible border that intersects the edge seal, the sidewall defining a body and a hood; and a primary insert both surfaces of which are affixed to the body, the primary insert comprising a peelable seal. Upon tearing of the frangible border, the hood is separated from the body. In use, a straw contacts the primary insert and opens the peelable seal which has not been exposed to the environment until the hood is removed.

What is claimed is: 
     
         1 . A packaging container for liquid, the container comprising:
 at least one sidewall comprising an edge seal and a frangible border that intersects the edge seal, the sidewall defining a body and a hood; and   a primary insert affixed to the body, the primary insert comprising a peelable seal.   
     
     
         2 . The packaging container of  claim 1 , wherein the sidewall comprises a first panel and a second panel whose edges are affixed thereby forming the edge seal. 
     
     
         3 . The packaging container of  claim 1 , wherein the peelable seal comprises a strength layer and a delamination layer such that upon contact by a straw the delamination layer separates from the strength layer thereby opening the peelable seal. 
     
     
         4 . The packaging container of  claim 1 , wherein upon tearing the frangible border, the hood and the body are separated. 
     
     
         5 . The packaging container of any one of  claim 1  further comprising a secondary insert affixed to one surface of the primary insert and to the body. 
     
     
         6 . The packaging container of  claim 1 , wherein the sidewall comprises an ethylene-vinyl alcohol (“EVOH”) copolymer or a foil film. 
     
     
         7 . The packing container of  claim 1 , further comprising one or more gussets, the container being formed into a stand-up pouch. 
     
     
         8 . The packaging container of  claim 1 , wherein a first surface of the primary insert at a first end towards the hood is affixed to the body and a second surface of the primary insert at a second end away from the hood is affixed to the body. 
     
     
         9 . The packaging container of  claim 3 , wherein the delamination layer comprises a polymer that is a pressure sensitive adhesive. 
     
     
         10 . A packaging container for liquid, the container comprising:
 a first panel and a second panel whose edges are affixed thereby forming an edge seal;   a frangible border along both the first panel and the second panel, the frangible seal intersecting the edge seal; and   a primary insert both surfaces of which are affixed to the body, the primary insert comprising a peelable seal that comprises a strength layer and a delamination layer such that upon contact by a straw the delamination layer separates from the strength layer thereby opening the peelable seal.   
     
     
         11 . The packaging container of  claim 10 , wherein a first surface of the primary insert at a first end towards the hood is affixed to the body and a second surface of the primary insert at a second end away from the hood is affixed to the body. 
     
     
         12 . A method of making a packaging container for a liquid, the method comprising:
 forming at least one sidewall by extruding a first polymer resin through a die or obtaining a foil film;   affixing a primary insert to the sidewall;   forming an edge seal by affixing the edges of the sidewall; and   forming a frangible border by scoring the sidewall.   
     
     
         13 . A method of delivering a liquid product in a packaging container, the method comprising:
 obtaining the packing container of  claim 1  comprising liquid product therein;   tearing the frangible border; and   inserting a straw through the peelable seal.   
     
     
         14 . The method of  claim 13  further comprising resealing the peelable seal.
