Dispenser for flexible material
First Claim
1. A dispenser comprisinga. a housing having an outlet opening thereinb. a spool,c. a spirally wound roll of flexible material mounted on said spool for rotation therewith(1) in one direction effective to unwind said flexible material from said roll, and(2) in another direction effective to wind said flexible material onto said roll,d. a hub mounted in said housing for rotatably supporting said spool,e. said spool being mounted on said hub for rotation therearound in said one direction,f. said hub being disposed in such position in said housing that said unwinding of said flexible material from said roll by pulling on said flexible material is effective to rotate said spool around said hub in said one direction,g. said spool having a plurality of inwardly projecting detents disposed in spaced relation to each other therearound, andh. said hub having a detent disposed in position thereon to so sequentially engage each of said plurality of detents during a complete rotation of said spool around said hub in said one direction as to resist but permit further rotation of said spool around said hub in said one direction.

Abstract
A dispenser for flexible material, wherein the material is disposed in a roll in a housing having a dispensing opening therein, and the material is dispensed by pulling thereon to thereby rotate the roll in the housing, detents being afforded on the roll and housing that are effective to periodically releasably resist further dispensing rotation of the roll during each rotation of the roll.

1. A dispenser comprising
a. a housing having an outlet opening therein b. a spool, c. a spirally wound roll of flexible material mounted on said spool for rotation therewith (1) in one direction effective to unwind said flexible material from said roll, and (2) in another direction effective to wind said flexible material onto said roll, d. a hub mounted in said housing for rotatably supporting said spool, e. said spool being mounted on said hub for rotation therearound in said one direction, f. said hub being disposed in such position in said housing that said unwinding of said flexible material from said roll by pulling on said flexible material is effective to rotate said spool around said hub in said one direction, g. said spool having a plurality of inwardly projecting detents disposed in spaced relation to each other therearound, and h. said hub having a detent disposed in position thereon to so sequentially engage each of said plurality of detents during a complete rotation of said spool around said hub in said one direction as to resist but permit further rotation of said spool around said hub in said one direction.

5. In a dispenser for pressure sensitive tape embodying a housing for a roll of such tape, and a cutter bar for severing an end portion of such tape from the remainder thereof and adhesively holding the free end portion of said remainder after said end portion has been so severed, the combination of
a. a hub disposed in said housing, b. a spool mounted on said hub for rotation therearound, c. a roll of pressure sensitive tape mounted on said spool for rotation therewith, d. said tape being disposed in a spiral around said spool in such position that tension applied to the outer free end of said tape toward said cutter bar will cause said roll and spool to rotate around said hub in a direction to unwind said tape from said roll toward said cutter bar, e. said hub having a detent on the outer periphery thereof, f. said spool having a plurality of detents on the inner periphery thereof, g. said detent on said hub being disposed in position to retardingly, but releasably, sequentially engage each detent of said plurality of detents during said tape-unwinding rotation of said roll and spool.
