Soap bar wrapper

Abstract

A method of wrapping a generally rectangular soap bar. In one aspect, the invention can be a method of wrapping a generally rectangular soap bar having a shared-bottom surface comprising wrapping a film laterally around said soap bar and overlapping the edges of said film that extend longitudinally across a bottom surface of said soap bar, placing said soap bar on a sealing plate that has a shape that is complementary to the shape of the bottom surface of said soap bar, folding the film at a longitudinal end of said soap bar, and sealing said overlapping edges of film and the folded film at the longitudinal end.

1 . A method of wrapping a generally rectangular soap bar having a shared-bottom surface comprising wrapping a film laterally around said soap bar and overlapping the edges of said film that extend longitudinally across a bottom surface of said soap bar, placing said soap bar on a sealing plate that has a shape that is complementary to the shape of the bottom surface of said soap bar, folding the film at a longitudinal end of said soap bar, and sealing said overlapping edges of film and the folded film at the longitudinal end. 
     
     
         2 . A method as in  claim 1  wherein the bottom surface of said soap bar is concave in shape and said sealing plate is convex shape. 
     
     
         3 . A method as in  claim 2  wherein said film is folded at both longitudinal ends of said soap bar. 
     
     
         4 . A method as in  claim 2  wherein the overlapping edges of film and the folded film at the longitudinal end are sealed at about the same time. 
     
     
         5 . A method as in  claim 2  wherein the overlapping edges of film and the folded film at the longitudinal end are sealed sequentially. 
     
     
         6 . A method as in  claim 2  wherein said film is a thermoplastic film having a thickness of about 60 micron to about 180 micron and a Taber stiffness of more than about 5. 
     
     
         7 . A method as in  claim 6  wherein said film is selected from the group consisting of polyethylenes, polypropylenes, vinyl polymers, acrylic polymers, styrenes and polyesters. 
     
     
         8 . A method as in  claim 7  wherein the film is biaxially oriented polypropylene.
