Bung for a paper roll

Abstract

The invention consists of a bung for a paper roll, the bung comprised of a core and a plurality of flanges frangibly coupled to the core. Each flange has a number of ridges that serve to anchor the flange to the paper roll. When the bung is inserted into a paper roll, the flanges are decoupled from the core, and serve to hold the core within the paper roll.

 a) a cylindrical core; and    b) a plurality of flanges frangibly coupled to said cylindrical core, each flange in said plurality of flanges having anchor ridges for contacting said paper roll;    wherein, when said bung is inserted into said paper roll, said flanges decouple from said cylindrical core and act to hold said cylindrical core within said paper roll.    
     
     
         2 . The bung according to  claim 1 , wherein said cylindrical core has a protruding end shaped so as to be couplable only to a specific dispenser.
