Holders for a roll core

Abstract

A roll core supporting apparatus comprises a pair of cylindrical handles. Each of the handles provides a generally circular side wall having a plurality of arcuate side wall segments adapted for compressive constraint within the roll core and outward spring bias deflection for gripping the roll core interiorly at one end. The pair of handles, then, are placed in each end of the roll core. The arcuate side wall segments may be axially oriented or circumferentially oriented. The side wall further provides a plurality of spaced-apart, axially-directed stiffening ribs. The roll core is supported by the two handles which allows the film to be dispensed from the roll as it rotates about the handles.

What is claimed is:  
     
         1 . A roll core supporting apparatus comprising at least one cylindrical handle, the at least one handle providing a generally circular side wall, the side wall comprising a plurality of side-by-side arcuate side wall segments adapted for outward spring bias deflection for gripping a roll core interiorly at one end thereof.  
     
     
         2 . The apparatus of    claim 1    wherein the arcuate side wall segments are axially oriented.  
     
     
         3 . The apparatus of    claim 1    wherein the arcuate side wall segments are circumferentially oriented.  
     
     
         4 . The apparatus of    claim 1    wherein the side wall further provides a plurality of spaced-apart, axially-directed stiffening ribs.  
     
     
         5 . The apparatus of    claim 1    further providing an integral outwardly directed flange at a proximal end of the side wall wherein the outwardly directed flange providing a peripheral stiffening lip.  
     
     
         6 . The apparatus of    claim 5    wherein the outwardly directed flange provides a plurality of integral spaced-apart corner ears extending radially outwardly therefrom.  
     
     
         7 . The apparatus of    claim 1    further providing an integral end wall at a distal end of the side wall.  
     
     
         8 . The apparatus of    claim 7    wherein the end wall provides a finger access aperture.  
     
     
         9 . The apparatus of    claim 1    wherein the side wall provides an axially directed seam enabled for parting the side wall.  
     
     
         10 . The apparatus of    claim 9    further comprising a means for sealing the axially directed seam.  
     
     
         11 . The apparatus of    claim 1    wherein a proximal portion of the side wall is generally non-tapered and a distal portion of the side wall is tapered, the tapered portion providing a sliding fit within the roll core, the non-tapered portion providing a compression fit within the roll core.  
     
     
         12 . The apparatus of    claim 1    constructed of a material having a low coefficient of friction for sliding in contact with a roll core.
