Abstract

Methods of forming flexible containers, the methods comprising joining together a first flexible material and a second flexible material, to form a joined material, using the joined material, at least partially forming a structural support volume and an expansion port in communication with the structural support volume, and by joining a third flexible material to the joined material, at least partially forming a product volume and a fill port in communication with the product volume.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of forming a flexible container, comprising:
 joining together a first flexible material and a second flexible material, to form a joined material;   using the joined material, at least partially forming a structural support volume and an expansion port in communication with the structural support volume; and   by joining a third flexible material to the joined material, at least partially forming a product volume and a fill port in communication with the product volume.   
     
     
         2 . The method of  claim 1 , further comprising:
 after the adding, sealing the fill port;   after the sealing, depositing an expansion material into the structural support volume, through the expansion port; and   after the depositing, sealing the expansion port.   
     
     
         3 . The method of  claim 1 , further comprising depositing an expansion material into the structural support volume, through the expansion port. 
     
     
         4 . The method of  claim 3 , wherein the depositing occurs while the container being formed is inverted. 
     
     
         5 . The method of  claim 4 , wherein the forming of the fill port occurs while the container being formed is inverted. 
     
     
         6 . The method of  claim 5 , wherein the forming of the expansion port occurs while the container being formed is inverted. 
     
     
         7 . The method of  claim 3 , wherein the depositing includes depositing the expansion material, which comprises one or more phase change materials. 
     
     
         8 . The method of  claim 7 , wherein the depositing includes depositing the expansion material, which includes liquid nitrogen. 
     
     
         9 . The method of  claim 1 , wherein the forming of the expansion port includes forming the expansion port from an open space located between two seals of the joined materials. 
     
     
         10 . The method of  claim 9 , wherein the forming of the expansion port includes forming the expansion port from the open space, which has a narrowest width from about 5 millimeters to about 10 millimeters. 
     
     
         11 . The method of  claim 1 , wherein the forming of the fill port includes forming the fill port from an open space located between two seals of the joined materials. 
     
     
         12 . The method of  claim 11 , wherein the forming of the fill port includes forming the fill port from the open space, which has a narrowest width from about 25 millimeters to about 75 millimeters. 
     
     
         13 . The method of  claim 1 , wherein the forming of the fill port includes forming the fill port, which is also configured to be a product dispensing port. 
     
     
         14 . The method of  claim 1 , further comprising removing air from the product volume. 
     
     
         15 . The method of  claim 1 , further comprising:
 opening the fill port; and   after the opening, adding a fluent product to the product volume, through the fill port.   
     
     
         16 . The method of  claim 15 , further comprising opening the fill port by gripping the flexible container. 
     
     
         17 . The method of  claim 16 , further comprising opening the fill port by gripping the flexible container with one or more vacuum grippers. 
     
     
         18 . The method of  claim 1 , further comprising:
 opening the expansion port; and   after the opening, depositing an expansion material into the structural support volume, through the expansion port.   
     
     
         19 . The method of  claim 18 , further comprising opening the fill port by gripping the flexible container. 
     
     
         20 . The method of  claim 19 , further comprising opening the fill port by gripping the flexible container with one or more vacuum grippers.
