Two-reel dispenser for a transfer adhesive
First Claim
1. A dispenser for a transfer adhesive, the dispenser comprising a supply reel, a take-up reel, and a tape of transfer adhesive, the supply reel and the take-up reel being geared together such that rotation of the take-up reel causes rotation of the supply reel, the tape being wound on the supply reel and on the take-up reel, the take-up reel having means for attachment of the tape thereto, the portion of the tape wound on the supply reel being disposed around a core, wherein the supply reel includes slip clutch means for frictional engagement of the supply reel with the core, and wherein the diameter of the supply reel is greater than that of the take-up reel.

Abstract
This invention is a dispenser for a transfer adhesive. The dispenser is less expensive to manufacture than comparable dispensers of the prior art, because it uses a single reel to perform the functions previously performed by two separate elements. A supply reel feeds a transfer adhesive tape to a take-up reel, which also acts as an applicator roller. The supply and take-up reels are connected together such that rotation of one causes rotation of the other. The user holds the dispenser so that the take-up reel presses firmly against the surface onto which the adhesive is to be applied. As the dispenser is moved along that surface, the take-up reel rotates due to friction, depositing adhesive and causing the supply reel to deliver more tape. The take-up and supply reels can be connected by gears or by a friction drive. If gears are used, they can be of a modified form which allows the take-up reel to drive the supply reel in only one direction. In another embodiment, a pinion gear or a one-way pin allow the supply reel to rotate in only one direction. Thus, if the user accidentally moves the take-up reel in the wrong direction, the supply reel will not create unwanted slack in the tape. In all embodiments, it is preferred to use a slip clutch to compensate for the differences in speeds of rotation of the take-up and supply reels.

- 1. A dispenser for a transfer adhesive, the dispenser comprising a supply reel, a take-up reel, and a tape of transfer adhesive, the supply reel and the take-up reel being geared together such that rotation of the take-up reel causes rotation of the supply reel, the tape being wound on the supply reel and on the take-up reel, the take-up reel having means for attachment of the tape thereto, the portion of the tape wound on the supply reel being disposed around a core, wherein the supply reel includes slip clutch means for frictional engagement of the supply reel with the core, and wherein the diameter of the supply reel is greater than that of the take-up reel.
- 6. A dispenser for a transfer adhesive, the dispenser comprising a supply reel, a take-up reel, and a tape of transfer adhesive, the supply reel and the take-up reel being disposed to contact a friction drive means, wherein rotation of the take-up reel causes rotation of the supply reel, the tape being wound on the supply reel and on the take-up reel, the take-up reel having means for attachment of the tape thereto, the portion of the tape wound on the supply reel being disposed around a core, and means for attaching the core to the supply reel such that the core does not rotate relative to the supply reel, and wherein the diameter of the supply reel is greater than that of the take-up reel.
- 11. A dispenser for a transfer adhesive, the dispenser comprising a supply reel and a take-up reel, the supply reel and take-up reels being connected together by a tape and by a connection means which is independent of the tape, such that rotation of the take-up reel causes rotation of the supply reel, wherein the take-up reel comprises means for applying the transfer adhesive to a surface, and wherein the dispenser includes means for maintaining a constant spacing between the centers of the supply reel and take-up reel while the reels are rotating.
- 22. A dispenser for a transfer adhesive, the dispenser comprising a supply reel and a take-up reel, the supply reel and take-up reels being geared together such that rotation of the take-up reel causes rotation of the supply reel, and a roll of transfer adhesive tape, the tape being wound on the supply reel and onto the take-up reel, wherein the take-up reel comprises means for applying the transfer adhesive to a surface, and wherein the dispenser includes means for maintaining a constant spacing between the centers of the supply reel and take-up reel while the reels are rotating.
-
27. A dispenser for a transfer adhesive, the dispenser comprising a supply reel and a take-up reel, the supply reel and take-up reels being connected to gears which are engaged with each other such that rotation of the take-up reel causes rotation of the supply reel, a roll of transfer adhesive tape, the tape being wound on the supply reel and onto the take-up reel, wherein the take-up reel comprises means for applying the transfer adhesive to a surface, the teeth of the gear connected to the take-up reel being modified such that every other tooth is cut away to define a step, and such that the unstepped teeth are cut away so as to delay engagement with the teeth of the supply reel, wherein the take-up reel can drive the supply reel in only one direction.
-
28. A dispenser for a transfer adhesive, the dispenser comprising a supply reel and a take-up reel, the supply reel and take-up reels being connected to gears which are engaged with other such that rotation of the take-up reel causes rotation of the supply reel, a roll of transfer adhesive tape, the tape being wound on the supply reel and onto the take-up reel, wherein the take-up reel comprises means for applying the transfer adhesive to a surface, the dispenser including a housing, the gear of the supply reel being connected to a pinion gear disposed within a wedge-shaped restriction, the restriction being connected to the housing, wherein the pinion gear can rotate normally when the supply reel rotates in a first direction, and wherein the pinion gear becomes stuck in the wedge-shaped restriction when the supply reel rotates in the opposite direction.
-
29. A dispenser for a transfer adhesive, the dispenser comprising a supply reel and a take-up reel, the supply reel and take-up reels being engaged with each other through a friction drive, such that rotation of the take-up reel causes rotation of the supply reel, a roll of transfer adhesive tape, the tape being wound on the supply reel and onto the take-up reel, wherein the take-up reel comprises means for applying the transfer adhesive to a surface, wherein the supply reel includes a one-way pin, the pin being disposed within a wedge-shaped restriction connected to the supply reel, wherein the pin permits unimpeded rotation of the reels in a first direction, and wherein the pin becomes stuck in the restriction when the reels rotate in the opposite direction.
