Sleeve for loading a dispensing device with bulk viscous material

Abstract

A sleeve is provided which is arranged for use during loading of bulk viscous material, such as latex and silicone caulking compounds, into the barrel of a device for dispensing such compounds. The loading sleeve comprises a slightly larger open proximal end for receiving the barrel and a slightly narrower open distal end. A sidewall tapers as it extends from the proximal end to the distal end of the sleeve to create an interference fit with the barrel of the dispensing device when the barrel is inserted into the sleeve. The sleeve also includes an inwardly extending flange located at the open distal end of the sleeve to provide a seat for the barrel of the dispensing device when it is inserted into the sleeve.

1 . A sleeve arranged for use during loading of bulk viscous material into the barrel of a bulk dispensing device, said sleeve comprising:
 a. a slightly larger open proximal end for receiving the barrel, and a slightly narrower open distal end;   b. a sidewall tapering as it extends from said proximal end to said distal end to create an interference fit when the dispensing device barrel is inserted into said sleeve; and,   c. an inwardly extending flange located at the open distal end of said sleeve to provide a seat for the dispensing device barrel when it is inserted into said sleeve.   
     
     
         2 . The sleeve of  claim 1 , wherein the open distal end includes a diameter of approximately 2.100 inches. 
     
     
         3 . The sleeve of  claim 1 , wherein said sidewall includes an outside surface, and wherein said sleeve additionally comprises at least one external rib located on said sidewall outside surface. 
     
     
         4 . The sleeve of  claim 3 , wherein said at least one external rib comprises three external ribs. 
     
     
         5 . The sleeve of  claim 1 , wherein said sleeve is arranged for use during loading of bulk viscous material from a pail or drum. 
     
     
         6 . The sleeve of  claim 1 , wherein said sidewall is of generally cylindrical construction.
