Pouch for a Food Product

Abstract

A method for producing pyramidal shaped pouches and filling them with a food product is disclosed. The method includes the steps of providing a multi-layered heat sealable material; forming a tube from the material via a forming shoulder and a metallic forming tube on which the material is wrapped; sealing along a longitudinal direction where the material overlaps to form a longitudinal sealing; sealing across the tube to generate a first sealing edge and forming an opening; filling via the metallic forming tube the food product in the opening; and sealing across the tube to close the opening and generate a second sealing edge. The method further includes creating a notch in the first sealing edge. A tear area extends substantially along the longitudinal sealing. Adjacent pouches are cut to be separated, each filled with the food product.

1 . A method for producing pyramidal shaped pouches and filling them with a food product, the method comprising:
 providing a multi-layered heat sealable material on a reel;   unwinding the material via rolls;   forming a tube from the material via a forming shoulder and a metallic forming tube on which the material is wrapped;   sealing along a longitudinal direction where the material overlaps to form a longitudinal sealing;   sealing across the tube to generate a first sealing edge and forming an opening, the first sealing edge being a first sealing edge for both of two adjacent pouches;   filling via the metallic forming tube the food product in the opening;   sealing across the tube to close the opening and generate a second sealing edge substantially orthogonally to the first sealing edge, the second sealing edge being a second sealing edge for one of the two pouches;   sealing across the tube to generate a third sealing edge substantially orthogonally to the first sealing edge after filling in the food product, the third sealing edge being a second sealing edge for another of the two pouches;   creating a notch in the first sealing edge adjacent the longitudinal sealing to form a tear area for generating an opening on each of the two adjacent pouches, the tear area extending substantially along the longitudinal sealing; and   cutting laterally along the first sealing edge to separate the two adjacent pouches, each filled with the food product.   
     
     
         2 . The method of  claim 1 , wherein sealing is performed by jaw pairs through opening and closing in a sequential pattern. 
     
     
         3 . The method of  claim 2 , wherein the jaw pairs are formed by two opposite metallic jaws. 
     
     
         4 . The method of  claim 2 , wherein sealing is performed by cross-sealing through the jaw pairs positioned underneath the metallic forming tube. 
     
     
         5 . The method of  claim 2 , wherein the jaw pairs are metallic and electrically heated. 
     
     
         6 . The method of  claim 1 , further comprising lowering the material by one pouch length after sealing and filling in the food product. 
     
     
         7 . The method of  claim 1 , further comprising moving each pouch via a fixed chute to a conveyor belt. 
     
     
         8 . A system for producing pyramidal shaped pouches and filling them with a food product, the system comprising a machine configured to perform a method comprising:
 holding a multi-layered heat sealable material on a reel;   unwinding the material via rolls;   forming a tube from the material via a forming shoulder and a metallic forming tube on which the material is wrapped;   sealing along a longitudinal direction where the material overlaps to form a longitudinal sealing;   sealing across the tube to generate a first sealing edge and forming an opening, the first sealing edge being a first sealing edge for both of two adjacent pouches;   filling via the metallic forming tube the food product in the opening;   sealing across the tube to close the opening and generate a second sealing edge substantially orthogonally to the first sealing edge, the second sealing edge being a second sealing edge for one of the two pouches;   sealing across the tube to generate a third sealing edge substantially orthogonally to the first sealing edge after filling in the food product, the third sealing edge being a second sealing edge for another of the two pouches;   creating a notch in the first sealing edge adjacent the longitudinal sealing to form a tear area for generating an opening on each of the two adjacent pouches, the tear area extending substantially along the longitudinal sealing; and   cutting laterally along the first sealing edge to separate the two adjacent pouches, each filled with the food product.   
     
     
         9 . The system of  claim 8 , wherein sealing is performed by jaw pairs through opening and closing in a sequential pattern. 
     
     
         10 . The system of  claim 9 , wherein the jaw pairs are formed by two opposite metallic jaws. 
     
     
         11 . The system of  claim 9 , wherein sealing is performed by cross-sealing through the jaw pairs positioned underneath the metallic forming tube. 
     
     
         12 . The system of  claim 9 , wherein the jaw pairs are metallic and electrically heated. 
     
     
         13 . The system of  claim 8 , wherein the method further comprises lowering the material by one pouch length after sealing and filling in the food product. 
     
     
         14 . The system of  claim 8 , wherein the method further comprises moving each pouch via a fixed chute to a conveyor belt.
