     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention is directed to perforated label assemblies and particularly those perforated label assemblies adapted to be applied to multi-portioned surfaces. 
         [0004]    2. Description of the Related Art 
         [0005]    One particular application of the present invention may be as a label assembly for electrical apparatus such as AC/DC converters for electronic devices. Many popular electronic devices include the same or substantially similar AC/DC converters, making it difficult to tell one user&#39;s from another&#39;s. Additionally, many AC/DC converters contain severable and/or interchangeable portions such as extension cord modules which are similarly difficult to tell apart. As such, once severed, it is also difficult to determine which severable portion corresponds to which primary portion. The present invention addresses these needs, and others, as will be discussed herein. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention is directed to a perforated label assembly which facilitates affixation of the label to multi-portioned surfaces which are severable from one another. As such, the present invention provides for a label assembly which may be removed from its backing as a single member and so affixed to each surface portion concurrently. The present invention also includes alignment strips which may be removed from the assembly after affixation thereof so as to avoid interfering with the severable portions of the surface. 
         [0007]    In one embodiment, a label of the present invention is to be affixed to an electrical apparatus such as an AC/DC adapter for an electronic device. As such, many electrical apparatus include multiple portions which are severable and/or interchangeable such as extension cord modules and the like. Additionally, AC/DC adapters for popular electronic devices are identical in appearance and difficult to tell apart at first glance. Thus, in such an embodiment, the present invention may comprise a decorative label for application to an electrical apparatus, as well as a severable portion thereof, which facilitates distinction of an individual&#39;s electrical apparatus from others. Furthermore, certain embodiments include structural features which facilitate affixation of the label to the electrical apparatus and severable portions. In one embodiment, the invention comprises a label assembly comprising at least one label member affixed to a backing. The label member may comprises at least one primary portion and at least one severable portion. The label member is configured to be removed from the backing as a single-member, specifically, without separation of the severable label portion from the primary label portion. As such, each of the primary and severable portions of the label member may be affixed to an electrical apparatus concurrently. Furthermore, the label member may be configured to be severable after affixation to the electrical apparatus. 
         [0008]    In one preferred embodiment, the primary label portions and severable label portions may be at least partially defined by perforation. Additionally, an alignment strip may be severably disposed between the primary label portions and severable label portions, itself at least partially defined by perforation. The perforation can comprise an alternating pattern of apertures and webs, each having predetermined dimensional quantities such as diameter. The apertures serve to concentrate stresses at the webs, thereby increasing the likelihood that a stress applied to the label member will result in a fracture or tear precisely at the web. A minimum stress required to fracture the web may be referred to as a perforation strength. Thus, in order to ensure that the label member may be easily removed from a backing as a single-member, the present invention is configured such that any forces applied to the label member during removal from the backing will not cause stresses in the webbing higher than the perforation strength. The perforation strength may be adjusted via a variety of parameters such as thickness of label members, diameter of perforation, and diameter of web. 
         [0009]    In one embodiment, the stresses experienced by the web are reduced below that of the perforation strength via optimization of the adhesion strength of the label member to the backing. The label member includes an adhesive layer on a rear face. The label member, via the adhesive layer, is at least temporarily affixed to the backing, partially to ensure that the label member is not inadvertently affixed to other surfaces, or does not collect debris during storage or transport. The minimum stress required to remove the adhesive layer from the backing may be referred to as an adhesion strength. The adhesion strength may be optimized via selection of appropriate adhesive layer compounds and backing materials. Ideally, a backing material of predetermined surface energy is selected so as to provide a minimally resistant release of the label member therefrom, but temporarily retain the label member on the backing. 
         [0010]    Alternatively, any of a variety of known adhesives and backing materials may be used, and the perforation strength itself may be optimized via modulation or variation of the dimensional characteristics of the perforation. For example, in order to increase perforation strength, the aperture diameter may be reduced, the web diameter may be increased, or the thickness of the label member may be increased. Conversely, decreasing perforation strength may be achieved via substantially opposite modulation or variation as recited above. 
         [0011]    In additional embodiments, the primary label portion and severable label portion are correspondingly dimensioned and configured with a primary portion and severable portion of an electrical apparatus, with an alignment strip correspondingly dimensioned to an interface of the electrical apparatus portions. Therefore, the primary label portion and severable label portion of the label member of the present invention may be affixed to the corresponding portions of the electrical apparatus concurrently, as a single-member, and via removal of alignment strips from the label member, provide for the severable operation of the electrical apparatus without interference from the label member. Additionally, the alignment strips may facilitate an aesthetically pleasing disposition of the label member upon the electrical apparatus by maintaining a predetermined spacing between each portion of the label member, and allowing a user to apply all such portions at one time. 
         [0012]    In an alternative embodiment, the primary label portion and severable label portion are correspondingly dimensioned and configured relative to at least a portion of the interface of the electrical apparatus, allowing the primary and severable label portions to comprise any of a variety of dimensions or configurations within an outer boundary of the primary and severable portions of the electrical apparatus. In a more preferred embodiment, the alignment strip is at least partially configured to correspond to an interface of the electrical apparatus. 
         [0013]    In yet another embodiment of the present invention, the invention may take advantage of waste heat produced by the electrical apparatus in order to activate a scented or aromatic compound disposed on or within the label member of the present invention, thereby increasing the emission of scented or aromatic particles from the compound. As such, users will be able to introduce additional functionality into their electrical apparatus via the release of virtually any of a variety of known aromatic compounds during use of the electrical apparatus. 
         [0014]    In yet further applications of the present invention, the label member may comprise a photoluminescent compound, or other types of luminescent material, which is capable of emitting light. In one embodiment, a phosphorescent medium is utilized such that the label member may absorb light and re-emit light. As such, the present invention adds additional functionality to the electrical apparatus by facilitating visual location of the apparatus in dark environments. 
         [0015]    These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0026]      FIG. 1  is a plan view of a perforated label assembly  10  in accordance with one embodiment of the present invention. The label assembly  10  includes a backing  1000  and two label members  100 . Each label member  100  is configured and dimensioned to be applied to a portion of an electrical apparatus (as depicted in  FIGS. 2-4 ). Each label member  100  includes a primary label portion  110  and severable label portion  120 . Each label member  100  also includes an alignment strip  200  including alignment strip portions  201  which are delineated from the label  100  via perforation  220 , and from each other via secondary perforation  230 . The alignment strip  200  depicted in  FIG. 1  is configured in an “L” shaped configuration which corresponds with structuring structural features of the surface to which the label  100  will be applied, as described below. It will be understood that the alignment strip  200  may comprise a variety of dimensions and configurations. 
         [0027]    Each alignment strip portion  201  includes a tabbed end  210  which protrudes beyond the boundary of the label member  100 . As such, the tabbed end  210  facilitates removal of the alignment strip portion  201  by providing a surface which is easily graspable by a user, once the label member  100  is applied to the desired surface. As such, the label member  100  is configured to be removed from the backing  1000  as a single member. 
         [0028]      FIG. 2  depicts a detail of the area of  FIG. 1  indicated as  2 . Therein, further details of the perforation  220  may be seen. Accordingly, the perforation  220  comprises a plurality of apertures  223  and webs  222  disposed along the perforation  220 . As such, when it is desired to remove the alignment strip portion  201 , the perforation  220  facilitates an orderly removal by concentrating stresses at each web  222 , thereby allowing the alignment strip channel  201  to be torn substantially along the perforation  220 . 
         [0029]      FIG. 3  is a section view taken along line  3 - 3  of  FIG. 2 . Therein, it can be seen that the apertures  223  extend through the thickness of the alignment strip portion  201 . It will be appreciated that in alternative embodiments the apertures  223  may only extend partially through the alignment strip portion  201  and in yet further embodiments the apertures  223  may extend into the backing  1000 , depending at least in part upon manufacturing processes used. It may also be seen that an adhesive coating  130  is applied to the label  100 , which is then disposed onto the backing  1000  at an interface  1010 . In at least one embodiment, the aperture size, aperture depth, web size, adhesive composition, and backing composition are cooperatively selected such that a force placed on the web  222  during removal of the label  100  from the backing  1000  is less than a force required to tear the webs  222 . Stated another way, at least some of the above referenced characteristics are selected such that a failure stress of the webs  223  is larger than the actual stress experienced by the webs  223  during removal of the label  100  from the backing  1000 . One way to accomplish such a relation may be to optimize the perforations  220 , such as optimizing the dimensional relationships between apertures  223  and webs  222 . Alternatively, one method might focus on reducing an adhesion strength between the adhesive layer  120  and backing  1000  at the interface  1010 . However, it will be appreciated that other dimensional and compositional relationships may also accomplish the goals of the present invention. 
         [0030]    In an additional embodiment, the adhesion strength between the adhesive coating  130  and the electrical apparatus is larger than the adhesion strength at the interface  1010 . Indeed, the adhesion strength between the adhesive coating  130  and the electrical apparatus may be larger than the perforation strength such that, after application of the label member  100  to the electrical apparatus, the alignment strip  200  may be removed by simply peeling it away from the electrical apparatus, tearing the perforation  220 , and leaving the desired primary label portion  110  and severable label portion  120  of the label member  100  adhered to the electrical apparatus. 
         [0031]      FIG. 4  is a plan view of one embodiment of a label member  100  of the present invention affixed to an electrical apparatus  2010 . As can be seen, the label member  100  has been removed from the backing  1000  (depicted in  FIG. 1 ) and affixed to the electrical apparatus  2010  as a single member, with alignment strip  200  connected to the primary label portion  110  and severable label portion  120 . 
         [0032]      FIG. 5  is a plan view of one embodiment of a label member  100  of the present invention affixed to an electrical apparatus  2010  and having an alignment strip portion  201  removed. In at least one embodiment, the alignment strip portion  201  may be removed by grasping the tabbed portion  210  and pulling, thereby separating the alignment strip portion  201  from the label member  100  at the perforations  220 . Additionally, as the depicted alignment strip is “L” shaped, a secondary perforation  230  may be disposed at an angled or radiused portion  231  therof so as to avoid unintentional tearing of the alignment strip portion  201  as it is removed. 
         [0033]    One feature of the present invention is the provision of an alignment spacing  300  due to removal of the alignment strip  200 . As can be seen, the electrical apparatus  2000  includes a primary portion  2010  and a secondary portion  2020 , which interconnect via an interface  2030 . The alignment strip  200  is correspondingly disposed and dimensioned to overlie the interface  2030  and provide a desired positioning of the primary label portion  110  and severable label portion  120  relative to the interface. As such, once the alignment strip  200  is removed, an alignment spacing  300  is provided such that the label member  100  does not interfere with operation or separation of the electrical apparatus  2000 . 
         [0034]      FIG. 6  is a plan view of one embodiment of a label member  100  affixed to an electrical apparatus  2000  and having alignment strip portions removed. As such, no portion of the label member  100  occupies the alignment spacing  300 , and the severable portion  2020  of the electrical apparatus  2000  may be severed and/or replaced without interference from the label member  100  of the present invention. Additionally, the primary label portion  110  and severable label portion  120  maintain a predetermined distance relative to both the interface  2030  and the outer boundary of the electrical apparatus  2000 . Such an orientation is facilitated by the single-member application of the label member  100 , as opposed to individually applying the primary label portion  110  and severable label portion  120 . As such, a precise and aesthetically pleasing arrangement of the label member  100  may be achieved via a substantially centered disposition of the single-member label member  100  on the electrical apparatus  2000 , as well as a provision of a predetermined alignment spacing  300  of a predetermined distance, created from removal of the alignment strip  200 . 
         [0035]      FIGS. 7 and 8  depict alternative embodiments of the present invention comprising different dimensional relationships relative to each other, as well as the embodiment depicted in  FIG. 1 . As such, the present invention may be easily adapted to fit a variety of electrical apparatus. For example, where the label  100  of  FIG. 1  comprises a substantially rounded square shape of approximately 2.5 inches on a side, the label  100 ′ of  FIG. 7  may comprise a dimension of 2.125 inches on a side, and the label  100 ″ of  FIG. 8  may comprise a dimension of 1.75 inches on a side. It will be appreciated that the dimensions of the alignment strip  200 ,  200 ′,  200 ″, such as width and length, may be accordingly adjusted to maintain a proportional relationship to the label  100 ,  100 ′,  100 ″ size and/or corresponding placement relative to an interface of the electrical apparatus. 
         [0036]    Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents. 
         [0037]    Now that the invention has been described,
