Bung for a paper roll
View Patent ↗The invention consists of a bung ( 10 ) for a paper roll. The bung is comprised of a body ( 12 ) and a roll contacting element ( 14 ) frangibly coupled to the body. When the bung ( 10 ) is inserted into the cylindrical opening of the paper roll, the roll contacting element ( 14 ) breaks off from the body ( 12 ).
1. A bung for a paper roll having a cylindrical opening, said bung comprising:
(a) a core; and
(b) a roll contacting element frangibly coupled to said core such that said roll contacting element breaks from said core when said bung is inserted into said cylindrical opening, said roll contacting element operative to maintain said core in said cylindrical opening.
2. The bung according to claim 1 , wherein said roll contacting element is comprised of a plurality of flanges that fold down to partially surround said core.
3. The bung according to claim 2 , wherein said plurality of flanges are three in number.
4. The hung according to claim 2 , wherein each flange in said plurality of flanges has anchor ridges on an outer surface thereof for contacting an inner cylindrical surface of the cylindrical opening of said paper roll.
5. The hung according to claim 2 , wherein each of said plurality of flanges are attached to said body by frangible tabs.
6. The hung according to claim 1 , wherein said roll contacting element is operative to hold said body within the cylindrical opening of said paper roll.
7. The hung according to claim 6 , wherein said body has a cylindrical-shaped protruding end rotatably couplable to a mounting element on a dispenser.
8. The bang according to claim 6 , wherein said plurality of flanges each include a Protruding lip extending outwardly at a first end of said flanges operative to stop said first end from entering further into the cylindrical opening of said paper roll upon insertion of said bung.
9. The bung according to claim 8 , wherein said plurality of flanges each include an inner plate extending inwardly at a second end of said flanges operative to contact an edge of a corresponding plate on said cylindrical core to prevent said cylindrical core from traveling too far into said paper roll when said flanges decouple from said cylindrical core.
