Description: FIELD OF THE INVENTION This invention relates generally to label dispensers, and more particularly, to label dispensers that dispense labels stored on a backing tape. BACKGROUND OF THE INVENTION Identification labels are used in a variety of construction and building projects. Such labels are typically used during wiring to help identify and distinguish individual wires, cables or conduits from others that are in the same area and look just the same. Proper labeling is of tremendous help in completing, inspecting and servicing a wiring installation. Proper labeling is also of help in other types of installations, such as plumbing, wherein it is helpful to identify and distinguish among several, often identically appearing structures. To assist those engaged in installing wiring, plumbing and the like, preformed, blank, adhesive labels have been developed. Such labels are typically distributed and stored on a rolled, elongate backing tape prior to use. As the labels are needed, they are pulled off the backing tape and wrapped around the wire or cable. Each label includes a blank surface on which identifying information can be written before the label is wrapped around the wire or cable. Various forms of dispensers have been developed for storing and dispensing such labels. Typically, such dispensers have included a housing for storing the roll of unused labels, a backing or writing surface that. supports the label while identifying information is written onto the label, and a dispensing end for dispensing the completed label. Although generally effective, prior label dispensers were sometimes awkwardly shaped, uncomfortable to hold and difficult to use. These drawbacks were real and significant to actual users who typically do not work at a desk and write on the labels with one hand while standing and holding the dispenser with the other. Additionally, given that labels and label dispensers are generally low cost, high volume items that compete largely on the basis of value and economy, prior label dispensers were frequently a compromise between effective functional design and manufacturing economy. Such prior label dispensers suffered from such problems as jamming within the dispenser, difficulty in removing labels from the dispenser and inability to permit writing on a label prior to its being dispensed. EP-A-0,373,217 discloses a hand labeller capable of sticking an elongated label. The labeller simultaneously carries out the feed of a beltlike tape and the sticking of the label by merely pressing a stocking roller for stocking the label to a surface and moving the roller. US-A-4,574,979 discloses a dispenser for a roll of masking tape having a row of labels therealong coated with pressure sensitive adhesive and constructed with means for automatically peeling the leading label from the tape without risk of opening the dispenser cover. US-A-3,793,123 discloses a container adapted to support a roll of interconnected separate labels with the container having laterally disposed fastening means thereupon and provided with an outlet opening. SUMMARY OF THE INVENTION According to the present invention, there is provided a label dispenser according to claim 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, and, in particular, to Figs. 1 and 2, a label dispenser 10 embodying various features of the invention is shown in a "ready-to-use" condition. The label dispenser 10 includes a generally tear-drop shaped enclosure 12 having an enlarged or storage end 14 and a tapered or dispensing end 16. The tear-drop shaped enclosure 12 is shaped so as to be easily hand-held by the user. Unused or fresh labels 18 are contained in the enlarged storage end 14 of the enclosure 12 and are dispensed at the tapered dispensing end 16. As each fresh label 18 passes from the storage end 14 to the dispensing end 16, it passes through an exposed area or "writing window" 20. Within the writing window 20, the label 18 is supported underneath by the dispenser and is accessible from above so that the user can write identifying information onto the label 18 before it is dispensed. In accordance with conventional practice, fresh labels 18 are initially obtained from the manufacturer in the form of a roll 22. The labels 18 themselves are mounted on an elongate, flexible backing tape 24 that holds the labels 18 until they are dispensed. In the illustrated embodiment, the roll 22 of fresh labels 18 is contained in the enlarged end 14 of the enclosure 12. The backing tape 24 holding the labels 18 is threaded through the window 20 toward the tapered dispensing end 16. The backing tape 24 itself, however, is looped back toward to the storage end 14 and exits the enclosure 12 through a tape discharge slot 26 in the bottom of the enclosure 12 near the storage end 14. The labels 18 on the backing tape 24, however, dispense forwardly through a dispensing slot 28 formed at the dispensing end 16 of the enclosure 12. In use, the user pulls the backing tape 24 through the tape discharge slot 26 sufficiently to advance a fresh label 18 to the window 20. After writing the desired identifying information on the fresh label 18, the user again pulls the backing tape 24 to advance the label 18. As the tape 24 bends around the dispensing end 16 of the enclosure 12, the labels 18 automatically peel away from the tape 24 and are discharged forwardly through the dispensing slot 28. Referring further to Figs. 3-5, the enclosure 12 comprises a single, unitary structure having a main housing 30, a top cover 32 and an access door 34. The enclosure 12 is preferably injection molded as a single, unitary piece using a suitable plastic, such as polypropylene, with a pair of integrally formed "live" hinges 36, 38 joining the top cover 32 and the access door 34, respectively, to the main housing 30. The design of the label dispenser 10 lends itself to forming the enclosure 12 in a single injection molding step using a single mold. Forming the enclosure 12 as a unitary member, and in a single step, greatly reduces manufacturing, handling, inventory and assembly costs. As illustrated, both the top cover 32 and main housing 30 are hollow and cooperate to define a compartment 40 for housing the roll 22 of fresh labels 18. The hinge 36 between top cover 32 and main housing 30 permits the top cover 32 and main housing 30 to be pivoted away from each other to expose and gain access to the compartment 40. New rolls 22 of fresh labels can thus be inserted into the enclosure 12 by pivoting the top cover 32 and main housing 30 away from each other. The access door 34 swings downwardly away from the underside of the main housing 30 on the hinge 38 and provides access to the underside of the main housing 30. Such access is useful in loading a fresh roll 22 oflabels 18 and simplifies the task of molding the main housing 30 as a single unit. The writing window 20 is defined through the cooperating relationship of the top cover 32 and main housing 30 when they are closed as shown in Figs. 1 and 2. The main housing 30 includes an upper ramp 42 that defines a writing surface for supporting or "backing up" a label 18 within the window 21 as it is being written upon. The overlying portion of the top cover 32 includes an elongate aperture 44 through which the writing surface, and a label 18 thereon, is exposed. The forward end of the aperture 44 is defined by a raised crossbar 46 under which the labels 18 pass as they are discharged from the dispenser 10. The rear end of the aperture is defined by a flange 48 that overlies and bears against the rear end of the upper ramp 42 when the top cover 32 and main housing 30 are closed. The backing tape 24 and the labels 18 thereon pass between the flange 48 and the upper ramp 42. This helps hold the backing tape 24 and the labels 18 firmly down and flat against the writing surface. The dispensing slot 28 through which the labels 18 pass as they are dispensed is defined between the raised crossbar 46 and the forward end of the main housing 30. The forward end of the main housing 30 is rounded and is vertically spaced from the raised crossbar 46 to form the dispensing slot 28. The forward end is also spaced horizontally from the forward end of the ramp 42 to form an additional or reversing slot 50 through which the backing tape 24, but not the labels 18 stuck thereon, is threaded. Preferably, the flange 48 overlaps the forward end of the ramp 42 as shown in Fig. 2 to help hold the backing tape 24 and labels 18 firmly down and flat against the writing surface. The forward end of the ramp 42 is preferably pointed as illustrated so that the backing tape 24 makes a sharp bend as it passes through the reversing slot 50. The resulting sharp bend of the backing tape 24 causes the labels 18 to peel away from the backing tape 24 and continue forwardly through the dispensing slot 28. As further illustrated in Fig. 2, the backing tape 24, after first being threaded through the reversing slot 50, exits the enclosure 12 through the tape discharge slot 26. The tape discharge slot 26, in turn, is defined between the non-hinged end of the access door 34 and the adjacent portion of the main housing 30 when the access door 34 is closed. Preferably, the adjacent portion of the main housing 30 is chamfered to avoid peeling the labels 18 off the backing tape 24 as the tape 24 and labels 18 are drawn from the roll 22. Preferably, the upper ramp 42 includes a downwardly extending leg 52 that terminates just above the access door 34. The backing tape 24 is thus confined between the access door 34 and the end of the leg 52 to help keep the backing tape 24 properly threaded along the access door 34 and through the tape discharge slot 26. Referring now to the cross-sectional view of Fig. 7, it will be understood that the upper ramp 42 of the main housing 30 projects upwardly from the sidewalls 54 of the main housing 30 as shown. In addition, the sidewalls 56 of the upper ramp 42 are inwardly recessed from the sidewalls 54 of the lower housing 30. This enables the sidewalls 58 of the top cover 32 to pass alongside the sidewalls 56 of the ramp 42 when the top cover 32 and main housing 30 are closed as illustrated. The sidewalls 58, 54 of the top cover 32 and main housing 30 thus cooperate to provide the label dispenser 10 with a smooth exterior. In addition, the spacing between the top cover and ramp sidewalls 58, 56 is sufficiently close so that friction therebetween helps keep the top cover 32 and main housing 30 together when the enclosure 12 is closed. Additionally, slots 60 and tabs 62 can be provided to help lock the top cover 32 and main housing 30 together. Similarly, the access door 34 is also received into a notched recess 64 formed in the lower surface of the main housing 30 and is retained by means of a similar tab 66 and slot 68 (Fig. 3) arrangement. A tongue 70 formed along the lower edge of the top cover 32 mates with a groove 72 formed along the top edge of the main housing 30 to help improve the seal between the top cover 32 and main housing 30 and to help keep the edges from moving laterally away from each other when the top cover 32 and main housing 30 are closed. The close fitting relationship of the various housing members provides a degree of water and dust resistance that help keep the labels 18 dry and clean even when the dispenser 10 is used in a wet or dusty environment. Finally, the upper end of the upper ramp 42 includes two raised guides 74 that help confine the backing tape 24 and fresh labels 18 within the window 20. To load the label dispenser 10 with a spool or roll 22 of fresh labels 18, the top cover 32 and main housing 30 are separated and the access door 34 is opened as shown in Fig. 3. The roll 22 is then placed in the compartment 40 with the leading edge of the backing tape 24 and labels 18 extending toward the ramp 42. The backing tape 24 and labels 18 are threaded over the top surface of the ramp 42 between the guides 70 toward the forward end of the main housing 30. The backing tape 24 is threaded through the reversing slot 50 and pulled toward the rear of the main housing 30 as shown in Fig. 4. The top cover 32 is then lowered and snapped into position as shown in Fig. 5. While keeping the end of the backing tape 24 pulled beyond the end of the lower opening in the main housing 30, the access door 34 is then closed and snapped into place, leaving the end of the backing tape 24 extending through the backing tape discharge slot 26. When the backing tape 24 is thereafter pulled through the backing tape discharge slot 26, the backing tape 24 and the labels 18 it carries are pulled from the roll 22 and pass, one at a time, through the writing window 20. As the backing tape 24 is further pulled, the inherent stiffness of the labels 18 causes them to separate from the backing tape 24 and pass through the discharge slot 26 as the backing tape 24 abruptly changes direction while passing through the reversing slot 50. Preferably, a pair of coaxially aligned holes 76 are formed through the sides of the label dispenser 10 near the dispensing end 16. These holes 72 permit the label dispenser 10 to be hung on a suitable hanger at a point of purchase display before the dispenser 10 is sold and then from the user's belt after it is sold. The label dispenser shown and described herein offers many advantages over prior designs. The one-piece enclosure configuration allows the dispenser to be formed in a single injection molding step. This greatly reduces the cost and complexity associated with manufacturing, organizing, storing, tracking and assembling multiple parts. The shape of the dispenser conforms to the users' hand, and fits easily within the users' pocket, to increase user comfort and convenience. The writing window is conveniently placed to simplify the task of writing labels. Finally, the water resistant, close-fitting relationship of the enclosure components protects the fresh labels from the elements when the label dispenser is used outdoors. While a particular embodiment of the invention has been shown and described, it will be obvious to those skilled in the art that changes and modifications can be made without departing from the invention in its broader aspects, and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
