Abstract

An apparatus for dispensing a two-part adhesive includes a first collapsible bag containing a first part of the two-part adhesive, a second collapsible bag containing a second part of the two-part adhesive, and a manifold that communicates with the first collapsible bag and the second collapsible bag. The manifold includes a first projection device that pierces the first collapsible bag and a second projection device that pierces the second collapsible bag. Each part flows from its respective collapsible bag into the manifold after the bag is pierced. The manifold directs each part of the two-part adhesive separately through the manifold and out of an exit of the manifold.

         2 . The apparatus of  claim 1  wherein the two parts of the two-part adhesive exits the manifold in about a 1:1 ratio. 
     
     
         3 . The apparatus of  claim 1  wherein the two parts of the two-part adhesive exits the manifold in a ratio where one part exceeds the other part. 
     
     
         4 . The apparatus of  claim 1  further comprising a nozzle that is coupled to the exit of the manifold. 
     
     
         5 . The apparatus of  claim 4  wherein the nozzle mixes the two parts together into a mixture that is ejected from the nozzle as the adhesive. 
     
     
         6 . The apparatus of  claim 5  wherein the nozzle  36  element mixing nozzle. 
     
     
         7 . The apparatus of  claim 4  wherein the manifold and the nozzle are a single unit. 
     
     
         8 . The apparatus of  claim 1  wherein each bag is made of a polyester film. 
     
     
         9 . The apparatus of  claim 8  wherein the polyester film is a biaxially-oriented polyethylene terephthalate. 
     
     
         10 . The apparatus of  claim 1  wherein the manifold is made of plastic. 
     
     
         11 . The apparatus of  claim 1  wherein the manifold is made of aluminum. 
     
     
         12 . The apparatus of  claim 1  further comprising a first member in which the first bag is positioned and a second member in which the second bag is positioned, each of the first and second members being coupled to the manifold. 
     
     
         13 . The apparatus of  claim 12  further comprising a first connector that couples the first member to the manifold and a second connector that couples the second member to the manifold, wherein the first projection device is located in the first connector and the second projection device is located in the second connector. 
     
     
         14 . The apparatus of  claim 12  wherein each of the first and second members are cylinders. 
     
     
         15 . The apparatus of  claim 12  wherein each of the first and second bags are compressed with a respective mechanism that applies a pressure to the bag to eject the first and second parts out of the respective bags. 
     
     
         16 . The apparatus of  claim 15  wherein the mechanism is a rack and pinion mechanism or a chain a sprocket mechanism. 
     
     
         17 . An apparatus for dispensing a two-part adhesive comprising:
 a first member that holds a first collapsible bag containing a first part of the two-part adhesive;   a second member that holds a second collapsible bag containing a second part of the two-part adhesive;   a manifold that is coupled to the first member and the second member and that communicates with the first collapsible bag and the second collapsible bag, the manifold including a first projection device that pierces the first collapsible bag and a second projection device that pierces the second collapsible bag,   wherein each part flows from its respective collapsible bag into the manifold after the bag is pierced and wherein the manifold directs each part of the two-part adhesive separately through the manifold and out of an exit of the manifold.   
     
     
         18 . The apparatus of  claim 17  further comprising a nozzle that is coupled to the exit of the manifold. 
     
     
         19 . The apparatus of  claim 18  wherein the nozzle mixes the two parts together into a mixture that is ejected from the nozzle as the adhesive. 
     
     
         20 . The apparatus of  claim 17  wherein each bag is made of a polyester film. 
     
     
         21 . The apparatus of  claim 17  further comprising a first connector that couples the first member to the manifold and a second connector that couples the second member to the manifold, wherein the first projection device is located in the first connector and the second projection device is located in the second connector. 
     
     
         22 . The apparatus of  claim 17  wherein each of the first and second members are cylinders. 
     
     
         23 . The apparatus of  claim 17  wherein each of the first and second bags are compressed with a respective mechanism that applies a pressure to the bag to eject the first and second parts out of the respective bags into the manifold.
