Abstract

A closure device for joining a barrel and receptacle comprising a cylindrical barrel having a barrel lip at one end of the cylindrical barrel, and a barrel base at a second end of the cylindrical barrel, an outside surface having an outside diameter attaching the barrel base to the barrel lip, a plurality of substantially triangular projections disposed on the outside surface aligned along the barrel base, an annular depression adjacent the barrel lip, a cylindrical receptacle for receiving said cylindrical barrel having a receptacle lip at one end of the cylindrical receptacle and a receptacle base at a second end of the cylindrical receptacle, an inside surface having an inside diameter wherein the inside diameter is nominally equal to the outside diameter of said barrel, a plurality of substantially triangular indentations disposed on the inside surface aligned along the receptacle base having a reciprocal shape to the triangular projections disposed on the outside surface along aligned along the barrel base, and an annular bead adjacent the receptacle lip.

What is claimed is:  
     
         1 . A closure device for joining a barrel and receptacle comprising; 
 a cylindrical barrel having a barrel lip at one end of said cylindrical barrel, and a barrel base at a second end of said cylindrical barrel,    an outside surface having an outside diameter attaching said barrel base to said barrel lip,    a plurality of substantially triangular projections disposed on said outside surface aligned along said barrel base,    an annular depression adjacent the barrel lip,    a cylindrical receptacle for receiving said cylindrical barrel having a receptacle lip at one end of said cylindrical receptacle and a receptacle base at a second end of said cylindrical receptacle,    an inside surface having an inside diameter wherein said inside diameter is nominally equal to said outside diameter of said barrel,    a plurality of substantially triangular indentations disposed on said inside surface aligned along said receptacle base having a reciprocal shape to said triangular projections disposed on said outside surface along aligned along said barrel base, and an annular bead adjacent the receptacle lip.    
     
     
         2 . A closure device according to    claim 1    having a plurality of annular depressions adjacent the barrel lip, and a plurality of annular beads adjacent the receptacle lip.  
     
     
         3 . A closure device according to    claim 1    wherein said barrel and receptacle are each connected to a container and cover respectively.  
     
     
         4 . A closure device according to    claim 1    wherein said barrel and receptacle have a perimeter of the shape chosen from the group comprising ellipsoid, square, pentagon, hexagon, heptagon or octagon.
