ONE HANDED SPOOL AND ROLLER TAPE DISPENSER FIELD OF THE INVENTION [0001] The present invention relates to an adhesive tape dispenser for applying adhesive tape while requiring only a single hand to apply and cut the tape to a desired length. BACKGROUND OF THE INVENTION [0002] Adhesive tape dispensers are available in various models and sizes. In general, adhesive tape dispensers are most widely known in the form of desk tape dispensers and hand-held dispensers requiring the use of two hands. Typically, the tape is stored on a roll and mounted on a spindle or post for revolving movement. The adhesive tape typically can be cut at the desired length by means of a blade. Many of these devices require multiple rollers and complicated cutting implements in order to operate. Tape dispensers requiring a large number of components are complicated to manufacture, large in overall size, and require complicated procedures for installing and changing rolls of adhesive tape. SUMMARY OF THE INVENTION [0003] It would be desirable to provide a tape dispenser that is simple in construction, relatively small in size, and/or is easy to install or change an empty roll of adhesive tape for a new roll of adhesive tape. The present invention can include a tape roll housing having at least one sidewall extending to at least partially enclose a roll of adhesive tape installed therein. The adhesive tape is installed to allow the adhesive side to be exposed for direct application to the article to be taped while passing over a first roller. A channel is provided for threading the tape through the channel to maintain the tape in a position adjacent the roller for application. A cutting element is provided downstream of the roller allowing one hand application of the tape to the article to be taped, and cutting of the tape with a single handed motion. [0004] The housing can include an enclosed roller chamber allowing the roller to be adequately supported while presenting at least a portion of the outer periphery of the roller externally for application of the tape to the article to be taped. The replaceable spool of adhesive tape can be mounted on a post, spindle or retainer clips. Optionally, the housing can include a partial cover enclosing the roll of adhesive tape between two sidewalls of the housing. The housing if desired can be bifurcated along a center line forming a clam shell configuration allowing easy removal and installation of spools of adhesive tape. [0005] Other applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0006] The description herein makes reference to the accompanying drawings wherein like reference numerals refer to like parts throughout the several views, and wherein: [0007] Figure 1 is a simplified side elevational view of a housing of a single handed spool and roller tape dispenser according to the present invention for applying adhesive tape to a surface; [0008] Figure 2 is an exploded perspective view of a single handed tape dispenser housing according to the present invention with at least a partial cover portion for enclosing a curved tape applicator surface or roller; and [0009] Figure 3 is an exploded perspective view of a single handed tape dispenser housing according to the present invention with a bifurcated housing forming a clam shell configuration for enclosing a spool of tape. DESCRIPTION OF THE PREFERRED EMBODIMENT [0010] Referring now to Figure 1 , a tape dispenser housing 10 according to the present invention allows a length of tape 22 to be dispensed on a surface 12 with one hand. The tape dispenser housing 10 can include a replaceable tape spool 14 and a dispenser case 34. The tape dispenser case 34 can form a spool retainer 40 for holding the spool of the tape roll 18 longitudinally, while allowing rotation of the tape spool 14 about the center of the spool retainer 40. The tape spool 14 can rotate around the retainer 40 as a length of tape 22 is dispensed. [0011] The length of tape 22 can be dispensed from the spool 14 through a tape channel 24. The channel 24 can be formed between a curved surface or roller 28 and a channel guide 26. The channel guide 26 is connected to one sidewall of the roller chamber 38 and the channel 24 defines an open slot through the opposite sidewall of the roller chamber 38 allowing the tape to be inserted between the roller 28 and the guide 26 through channel 24. The length of tape 22 can be dispensed through the channel 24, so that the adhesive side 20 of the length of tape 22 can be in contact with a surface 12. If a roller 28 is provided, the roller 28 can rotate about a center axis 30 allowing the dispenser housing 10 to glide smoothly along a surface 12 to be taped. The channel guide 26 can keep the length of tape 22 in the channel 24 ensuring that the length of tape 22 is smoothly pressed on the desired location of a surface as the roller 28 glides along a surface 12. The channel guide 26 can contact the adhesive side 20 of the tape 22 to releasibly hold the tape 22 in position for subsequent dispensing after being cut. [0012] The dispenser casing 34 can be made up of two chambers, a tape spool chamber 36 and an enclosed roller chamber 38. The tape spool chamber 36 can hold the spool 14 in place allowing rotation about the spool retainer 40. If desired, the tape spool chamber can be enclosed, open, or partially enclosed. By way of example and not limitation, the tape spool chamber can be formed of plastic, such as injection molded plastic, and can be partially enclosed with a paper or cardboard insert. The spool chamber can also be enclosed by a plastic injection molded portion forming a clam-shell enclosure with the tape spool chamber. The roller chamber 38 can house the curved surface or roller 28. If a roller 28 is provided, the roller 28 can be held in place by a center pin 30 allowing rotational movement about the central axis 30. A metal or plastic cutting element or blade 32 can be parallel to the central axis 30 of the roller on the outside edge of the roller chamber portion 38of the casing 34. As a length of tape 22 is dispensed through the channel 24 via the curved surface or roller 28 onto a surface 12, the length of tape 22 can be detached from the tape dispensing device 10 at the desired length using the cutter blade 32. A portion 48 of the sidewall of the casing 34 adjacent the path of the tape 22 is optional and can be eliminated or reduced in dimension if desired, provided sufficient support is provided to the channel guide 26 in other ways. [0013] A single handed tape dispenser according to the present invention can include a housing defining a tape spool chamber and an enclosed chamber. The enclosed chamber can support a adhesive tape applicator curved surface or roller for contacting the non-adhesive side of the tape to be dispensed, while the adhesive side is presented outwardly for contact with a surface of an article to be taped. The enclosed chamber supports a cutter element downstream of the curved surface or roller allowing single handed application of the tape to the article to be taped and cutting of the tape to the desired length. The enclosed chamber also can include a channel guide for directing the tape to be dispensed over the curved surface or roller toward the cutter element. The tape spool chamber can include a spool retainer for receiving a replaceable spool of adhesive tape to be dispensed. The tape spool chamber can be enclosed, open, or partially enclosed. The tape spool chamber can be formed of plastic and can be partially enclosed with a paper or cardboard insert, and/or can be enclosed by a plastic injection molded portion forming a clam-shell enclosure in combination with the tape spool chamber portion of the tape dispenser housing.
