Abstract:
A device for dispensing a label from a backing strip comprises a cartridge, a tab, and a detaching mechanism. The tab includes a first side, a second side and distal end. The detaching mechanism is configured to operatively cause the strip of backing material to be routed along each of the first and second sides of the tab and configured to detach the label from the strip of backing material as the corresponding strip of backing material traverses the distal end of said tab.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a label dispensing device and more particularly, to a device for dispensing individual labels from a roll of labels contained in a cartridge so that the labels may be removed manually from the label backing and applied to a product. 
     2. Description of the Related Art 
     The challenges facing all businesses today are numerous and complex. Even the challenge of determining inventory or the price to charge for a commodity within a package can at times be overwhelming for the small business. Bar coding and scanning have helped to alleviate some of these challenges and have proven very successful as is evident by the widespread use of scanning from grocery stores and department stores to book stores and auto parts stores. Nonetheless, there are still problems within the industry for those business entities that must apply the bar code label or other types of identifying labels to the final product that is to be placed into the stream of commerce. One of those problems is the ability to rapidly and reliably dispense, at minimal cost, labels from a dispenser containing a roll of labels so that they may be applied to products. 
     A label dispenser having a complex mechanical configuration is disclosed in U.S. Pat. No. 3,369,952 to Rieger. That system incorporates a drive mechanism utilizing an electric drive motor and a tape conveying system. The teachings of the &#39;952 patent are incorporate herein by reference. 
     The low end of the market for label dispensing devices, however, has not developed to any great extent. Particularly, a need exists for dispensers that can rapidly and reliably dispense labels and not require a considerable financial investment for the purchase of the dispensing device. The simplicity of the present invention minimizes the potential for mechanical problems, provides for rapid dispensing and allows the dispensing device to be manufactured inexpensively. In addition, the carrying case provided with the dispensing device allows it to be secured to the wearer&#39;s clothing such that hands can be freed to perform other useful work without any loss of time. With the label dispenser safely and securely in place within the holder and the labels at the ready for dispensing, the present invention combines many desirable elements including; reliability, rapid operation and ease of use and safeguarding within the carrying case. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a rapid, reliable, readily securable and inexpensive means of dispensing labels. 
     Other objects and advantages of this invention will become apparent from the following description in conjunction with the accompanying drawings. 
     These objects are attained by the present invention, which provides a system for dispensing an individual label from a roll of labels. The system comprises a cartridge formed from a single strip of material for retaining the labels and the label backing material within a cavity formed within the cartridge. The cartridge is formed from a single strip of material configured such that a roughly rectangular cavity is formed with one end of the strip overlapping the other end creating a tab with an internal wall facing in the direction of the cavity and an external wall facing away from the cavity, and with a gap between the end of the strip and the tab sufficient for the labels and backing material to pass between the two with no interference. A cross member attached in a perpendicular fashion to the edges of two of the walls serves as a fifth wall of the cartridge and further bounds the volume of space which the roll of labels may occupy. 
     As the labels and backing material are pulled from the cartridge they are routed along the tab, under a restraining device configured to retain the backing material in place as it travels along the internal wall of the tab, over the end of the tab and along the external wall of the tab in the opposite direction from the backing material and labels traveling the internal wall. The end of the tab over which the backing material traverses is fairly smooth resulting in the development of minimal friction between the backing and the edge itself. The smoothness of the edge serves to avoid damage to, and tearing of, the backing as it passes over the edge and rapidly reverses direction. 
     In a more specific aspect of the invention, the restraining device may include a spring, wrapped around the tab, and secured in place by notches in the edges of the tab. Once the backing material and labels are secured in place by the restraining device they must follow a prescribed path. As the backing and labels are pulled from the cartridge and approach the end of the strip, the longitudinal stiffness of the labels begin to overcome the adhesive binding the labels to the backing resulting in delamination of the labels from the backing. Once delamination begins, the labels are readily removed, principally by manual means, from the backing for placement on a product. 
     According to the present invention, there is further provided a carrying case for the label dispensing device comprising a pouch attached to a backing that in turn can be attached to a wearer&#39;s clothing. The carrying case facilitates the transport and use of the label dispensing device. The cartridge fits within the pouch with the tab protruding in a substantially vertical direction and the label backing material trailing from under the restraining device on the external wall. The dispensing device is typically secured in place inside of the carrying case by a strap or similar mechanism.

     DETAILED DESCRIPTION OF THE INVENTION 
     Reference will now be made in detail to the preferred embodiment of the present invention, an example of which is illustrated in the accompanying figures. Whenever possible, the same reference numbers will be used throughout the description and figures to refer to the same or like parts. 
     A label dispensing device of the present invention is indicated generally at  10 . The label dispensing device  10  includes a cartridge  12  for retaining a roll of labels, a rigid wall, and a detaching mechanism for detaching a label from the roll of labels. 
     As shown in FIG. 2, the cartridge is generally rectangular shaped object having walls  51 ,  52 ,  53  and  54 , which form a cavity  57  configured to contain the roll of labels  45 . The cartridge includes a tab  41  on wall  54  as shown in FIG. 2, which extends beyond the intersecting wall  51 . The roll of labels  45  are further secured within the cavity by a cross member  62 , which extends from wall  54  to opposing wall  52  to prevent the roll from dropping from the cartridge. 
     As shown in FIG. 3, a gap  63  is provided between the intersecting wall  51  and tab  41  through which the roll of labels, which includes at least one label  48  and the backing material  37 , are fed. As the labels  48  and backing material  37  are extracted from the cavity  57  they pass through gap  63  and are routed along an inner wall  67  of the tab, under a restraining device  39 , over a distal end of the tab  41 , along a second side  71  of the tab and under the restraining device  39 . 
     As shown in FIG. 3, once the label backing material  37  begins to reverse direction at the distal end of the strip—as the label backing material moves from the first side to the second side of the tab  41 —the label  48  of the roll of labels positioned at this juncture delaminates from the backing material due to the longitudinal stiffness of the label overcoming the adhesive. As such, this partially delaminated label is easily removed manually from the backing material. The backing material  37  continues its path over the distal end of the strip  59 , down the external wall of the tab  71  and under the restraining device  39  thereby forcing the label from the backing strip. 
     As shown in FIG. 4, the restraining device is preferably a spring that is held in place by notches  73 ,  74 . The spring is circumjacent the sides of the tab  4  and, as mounted on the tab, is elastically deformed from its at rest position to securely remain on the tab  41  of the dispensing device  10 . The notches  73 ,  74  are formed on the edges of the tab  41 , slightly below the distal end of the strip  59 . 
     Preferably, the label dispensing device includes a carrying case  15  for holding the cartridge  12 . The carrying case  15  is comprised of three walls  23 ,  24  and  25 , the backing panel  19  and a bottom wall  27 . The walls  23 ,  24 ,  25  and  27  are attached to the backing panel by a series of rivets  29  or other similar attachment mechanisms. The label peeling device is attached to a wearer&#39;s belt  17  by routing the wearer&#39;s belt through slots  18  in the backing panel  19  of the carrying case. In order to secure the label peeling cartridge  12  within the carrying case  15 , a strap  31  with a snap  33  is utilized for restraint. The strap extends from the backing panel  19 , over the label peeling cartridge  12  and to the snap  33  which is located on the front wall  24  of the carrying case  15 . 
     FIG. 1 represents the label peeling device configuration as it would likely be in actual operation, wherein the backing material  37  exits from under the restraining device  39  which surrounds a portion of the tab  41  that protrudes from the carrying case  15 . In order to operate the label peeling device  10 , manual force is applied to the label backing material  37  at, or near its free end  43 . As the backing material  37  is pulled, the roll of labels  45  within the label peeling cartridge  12  unravels and feeds additional backing material  37  and labels  48  along the tab  41 . 
     In use, an operator would insert a roll of labels  45  into the cavity  57  of the label peeling cartridge  12 . The labels  48  and the backing material  37  would then be threaded through the gap  63  between the intersecting wall and tab  41 , under the restraining device  39 , over the distal end of the tab and once again under the restraining device  39  on the external wall  71  of the tab. 
     An application of force to the label backing material causes a label to be extracted from the cartridge  12  and, at the point where the backing material  37  reverses direction as it moves over the distal end of tab  41 , the label delaminates from the backing material. The backing material  37  remains adjacent both the first and second sides of the tab  41  because the backing material is constrained against the sides of the tabs by the restraining device  39 . As the backing material moves over the distal end of the strip  59 , reversing direction in a short interval, the adhesive binding the labels  48  and backing material  37  together cannot overcome the inherent stiffness of the label thereby causing the label to delaminate from the backing. As a label  48  delaminates, it can readily be removed from the backing material for application to a product. Repeating the process enables additional labels to be withdrawn from the cartridge and removed from the backing material.
