Abstract
Inserts for facilitating dispensing of wrapping material comprising an elongated web wrapped about a hollow cylindrical core. The inserts are telescopingly received within opposite ends of the hollow cylindrical core and are retained by a force-fit cylinder freely slidable relative to the insert and adapted to be force-fit within the hollow cylindrical core, enabling the web supply and its supporting core to be rotated relative to the inserts, while an operator holds the inserts during dispensing and wrapping operations.
Claims10
Inserts for use in supporting a dispensing web wrapped about a hollow cylindrical core, each of said inserts comprising:
- a substantially hollow cylindrical section having a first and second end, the diameter of said cylindrical section being substantially constant over the length thereof;
- a substantially flat annular-shaped flange integral with and extending outwardly from the first end of said cylindrical section;
- cylinder retainer means integral with and extending outwardly from the second end of said cylindrical section the diameter of the outer edge of said cylinder retainer means being less than the outer diameter of said first flange;
- a hollow cylindrical-shaped force-fit cylinder encircling said hollow cylindrical section and having a length less than the distance between said first flange and said cylinder retainer means so as to be loosely retained about said hollow section and between said first flange and said cylinder retainer means, said force-fit cylinder and said cylindrical section being rotatably slidable relative to one another;
- the outer diameter of said force-fit cylinder being at least equal to and preferably slightly greater than the inner diameter of said hollow cylindrical core for force-fittingly retaining said insert within said hollow cylindrical core, while enabling the cylindrical section of said insert to be freely rotatably slidable relative to said hollow cylindrical core.
