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 t…
