Dispensing pouch and a method of making the same

Abstract

A dispensing pouch and method for making the same are described. One described dispensing pouch includes a flexible first sheet and a flexible second sheet, each including at least one layer, and where the flexible second sheet has substantially the same size and shape as the flexible first sheet. The flexible second sheet is joined to the flexible first sheet to define a compartment configured to substantially contain a material. The flexible first sheet and the flexible second sheet also define a channel configured to allow dispensing of the material from the compartment.

1 . A dispensing pouch comprising: 
 a flexible first sheet comprising at least one layer; and    a flexible second sheet comprising at least one layer and having substantially the same size and shape as the flexible first sheet, the flexible second sheet joined to the flexible first sheet to define:    (1) a compartment configured to substantially contain a material, and    (2) a channel configured to allow dispensing of the material from the compartment.    
     
     
         2 . The dispensing pouch of  claim 1 , further comprising at least one notch formed on opposite sides of the dispensing pouch, the at least one notch configured to allow a user to tear a portion of the pouch to allow dispensing of material from the compartment through the channel.  
     
     
         3 . The dispensing pouch of  claim 1 , wherein the flexible first and second sheets each comprises a three-layer of material.  
     
     
         4 . The dispensing pouch of  claim 3 , wherein an outer layer of the three-layer material comprises polyethelene terephthalate.  
     
     
         5 . The dispensing pouch of  claim 3 , wherein a middle layer of the three-layer material comprises foil.  
     
     
         6 . The dispensing pouch of  claim 3 , wherein an inner layer of the three-layer material has a melting point lower than the middle and outer layers.  
     
     
         7 . The dispensing pouch of  claim 1 , wherein the flexible first sheet comprises an outer layer comprising paper.  
     
     
         8 . The dispensing pouch of  claim 1 , wherein the flexible first sheet and the flexible second sheet are part of a single flexible sheet that has been folded to create the flexible first sheet and the flexible second sheet.  
     
     
         9 . The dispensing pouch of  claim 1 , wherein the flexible first sheet and the flexible second sheet are joined by one or more seals.  
     
     
         10 . The dispensing pouch of  claim 1 , wherein the flexible first sheet comprises a first side and a second side, which are substantially parallel to each other, and a third and a fourth side which are substantially parallel to each other, and substantially perpendicular to the first side and the second side.  
     
     
         11 . The dispensing pouch of  claim 1 , wherein the dispensing pouch is configured to dispense a single drop of material.  
     
     
         12 . The dispensing pouch  claim 11  wherein the single drop of material hangs on the end of the dispensing pouch.  
     
     
         13 . The dispensing pouch of  claim 1 , wherein the dispensing pouch is configured to dispense less than 1 ml of solution.  
     
     
         14 . The dispensing pouch of  claim 1 , wherein the width of the channel is approximately between 1/32 of an inch and ⅛ of an inch.  
     
     
         15 . The dispensing pouch of  claim 1 , wherein the material comprises a liquid configured to mimic blood.  
     
     
         16 . A method of manufacture of a dispensing pouch comprising the steps of: 
 joining a flexible first sheet to a flexible second sheet along a first side, a second side, and a third side of the flexible first sheet and the flexible second sheet to define a compartment;    forming a channel extending from a fourth side of the flexible first sheet and a fourth side of the flexible second sheet to the compartment;    inserting a material into the compartment; and    sealing the channel along the fourth side of the flexible first sheet and the fourth side of the flexible second sheet.    
     
     
         17 . The method of  claim 16 , further comprising folding a single flexible sheet to form the flexible first sheet and the flexible second sheet.  
     
     
         18 . The method of  claim 16 , wherein joining the flexible first and second sheets comprises sealing the corresponding first, second, and third sides of the flexible first sheet and the flexible second sheet.  
     
     
         19 . The method of  claim 18 , wherein sealing the dispensing pouch comprises applying heating bars to the pouch.  
     
     
         20 . The method of  claim 16 , wherein forming the channel comprises placing a heat-sinking material between the flexible first sheet and the flexible second sheet and applying heat.  
     
     
         21 . The method of  claim 16 , further comprising forming a first notch on one side of the joined sheets adjacent to the fourth side of the joined sheets.  
     
     
         22 . The method of  claim 21  further comprising forming a second notch on the other side of the joined sheets adjacent to the fourth side of the joined sheets.  
     
     
         23 . The method of  claim 16 , further comprising creating a plurality of dispensing pouches from two large sheets, and perforating the large sheets between each of the plurality of dispensing pouches.  
     
     
         24 . The method of  claim 16 , further comprising cutting a hang hole into the dispensing pouch.  
     
     
         25 . The method of  claim 16 , further comprising one of stamping, debossing, or printing a code on the dispensing pouch.  
     
     
         26 . The method of  claim 16 , further comprising sterilizing the dispensing pouch.
