The present invention relates to an apparatus for dispensing rolled material having a pressure adhesive. In particular, the invention relates to a hand-operated rolled material dispensing apparatus for applying rolled material to a variety of surfaces, such as walls, windows, vehicles and the like in preparation for painting.
Rolled material dispensers are known. Typically a rolled material dispenser comprises a dispenser structure which rotatably supports a rolled material. After the desired amount of rolled material is dispensed a cutting element, located on the dispenser, is placed in cutting engagement with the payed out material and the dispenser is manipulated to cut the payed out material. In prior art rolled material dispensers, a twisting, cutting action is used to cut the payed out material. This twisting action is required in order to increase the pressure on the payed out material at one edge along the width of the payed out material to make the cutting operation easier. It is desirable to provide a more versatile rolled material dispenser whereby the payed out material cutting action can be easily done without twisting either the payed out material or the rolled material dispensing device.
Prior art rolled material dispensers are provided with a single cutting means, which restricts both the direction in which the rolled material can be dispensed, as well as the ease of use of the rolled material dispenser by both right and left-handed operators. Accordingly, it is desirable to provide a rolled material dispenser that can dispense rolled material in any direction and can be easily operated by both right and left-handed operators.
The rolled material dispenser of the present invention is a hand-operated one-piece, plastic molded dispenser. The rolled material dispenser comprises a body having a cylindrical hand grip and a first spindle. The first spindle securely and rotatably receives a spool. The spool is sized to receive standard sized rolled material and can rotate freely in either direction to payout the rolled material depending on the application direction desired. Two more spindles also extend from the body, each rotatably receiving an application wheel. Each application wheel has a cylindrical shape having a slightly raised washer-like element circumferentially attached at each end thereof.
Two cutting elements are integrally molded on either side of two application wheels that are provided for guiding the payed out material during application. The cutting elements have a specialized angled orientation to be described later which permits a simple rotation of the dispenser to cut the payed out material, as opposed to a twisting action. During the cutting operation only a few teeth engage the payed out material at any one time, thereby increasing the pressure applied to the payed out material, without the need to twist the payed out material or the rolled material dispenser.
In operation, the rolled material is loaded onto the spool, to payout in the selected direction, right or left. The raised rubber rings on the application wheels allow the operator to apply pressure along the edge of the payed out material during the dispensing operation.
The two cutting elements are offset from the plane of the payed out material so that they do not engage the payed out material during the dispensing operation. After the desired amount of payed out material has been dispensed the operator may rotate the rolled material dispenser about its horizontal axis until the cutting elements engage the payed out material. At the point of engagement with the payed out material, the cutting elements are oriented perpendicular to the payed out material, producing a straight cut.
The two cutting elements are positioned symmetrically about the vertical axis of the rolled material dispenser. This symmetrical configuration enables the dispensing of the rolled material to be performed in both directions, depending on need. Furthermore, the symmetrical configuration enables both right and left-hand operators to operate the rolled material dispenser with ease.
Further features of the invention will be described or will become apparent in the course of the following detailed description.
In order that the invention may be more clearly understood, embodiments thereof will now be described in detail by way of example, with reference to the accompanying drawings, in which:

A means for sliding along a surface 11 may be used on the outer most coplanar surfaces of the spool 2 and application wheels 9 and 10. The means for sliding along a surface 11 may be a cloth-like material or other material that reduces friction and prevents damage. This enables the rolled material dispenser to be operated in close proximity or even in contact with a flat surface, without damaging the adjacent or abutting perpendicular surface. An example of such an application is the dispensing of rolled material 3 in the corner formed by two walls. The rolled material dispenser may be in engaged with an application surface 15 (shown in
As well, the coplanar feature of the rolled material dispenser permits easy loading of the rolled material 3. The loading operation consists of placing a rolled material 3 in partial circumferential engagement over the spool 2. Thereafter, the rolled material dispenser is manipulated to press the rolled material 3 against a flat surface, which loads the rolled material 3 onto the spool 2, all elements are coplanar. In this manner the rolled material 3 is loaded correctly and remains in the correct position.
The two application wheels 9 and 10 are plastic cylinders. Raised rubber washers 12 are circumferentially attached over the ends of application wheels 9 and 10. During the dispensing operation the payed out material 24 travels under the application wheels 9 and 10 with the non-adhesive side in substantial contact with the rubber washers 12. The pressure adhesive side of the payed out material 24 is in contact with the surface 16 for application. The function of the rubber washers 12 is to enable the operator to apply pressure to the rolled material dispenser such that only the outside edges of the payed out material 24 make adhesive contact with the surface. This provides the advantage of eliminating the risk of damaging the painted surface thereunder during removal of the tape, which is likely if the entire rolled material 3 is adhesively applied to the surface. Another advantage is that the payed out material 24 can be more easily removed after application.
The two cutting elements 4 and 5 are aligned substantially vertical to engage the horizontal plane of the payed out material 24, as can be seen in

In all embodiments, the rolled material 3 may be a double sided pressure adhesive rolled material. The double sided rolled material may be thread in the same manner as the payed out material 24 above, with the release strip remaining intact until after application.
Other advantages, which are inherent to the structure, are obvious to one skilled in the art. The embodiments are described herein illustratively and are not meant to limit the scope of the invention as claimed. Variations of the foregoing embodiments will be evident to a person of ordinary skill and are intended by the inventor to be encompassed by the following claims.
