Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a pack wrapper opening system and more particularly to a system that removes the plastic wrapper from a package for access to the contents of the package.




2. Description of the Prior Art




Most compact discs and cassettes are sold encased in a plastic wrapper. These plastic wrappers are often difficult to remove and tend to lead to frustration for those who are attempting to remove them. People often resort to using knives or other sharp objects to attempt to remove the wrappers. This sometimes results in damaging the package and also injury to themselves or others. What is needed is a device that will allow for the simple removal of these plastic wrappers so that the user can easily access the packages and the compact disc and cassettes that are stored within these packages.




The present invention solves these problems by providing a device that will allow for the easy removal of plastic wrappers from packages without the use of a knife or other sharp object.




The use of opening systems is known in the prior art. More specifically, opening systems heretofore devised and utilized for the purpose of removing wrappers from packages are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.




By way of example, U.S. Pat. No. 5,666,731 to Rungren discloses a hand held device used to cut shrink wrap packages such as compact disc cases and is comprised of a cutting blade and guide assembly. U.S. Pat. No. 5,333,381 to Gelardi discloses a device for cutting tape on products such as video cassette boxes comprised of an angled blade device. U.S. Pat. No. 5,555,624 to McCracken discloses a pack opening system comprised of an edge guide and channel.




While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a pack wrapper opening system for removing the plastic wrapper from a package for access to the contents of the package.




In this respect, the pack opening system according to the present invention departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of safely removing the plastic wrapper from a package for access to the contents of the package.




Therefore, it can be appreciated that there exists a continuing need for new and improved pack wrapper opening system which can be used for removing the plastic wrapper from a package for access to the contents of the package. In this regard, the present invention substantially fulfills this need.




SUMMARY OF THE INVENTION




In view of the foregoing disadvantages inherent in the known types of opening systems now present in the prior art, the present invention provides an improved pack wrapper opening system and method which has all the advantages of the prior art and none of the disadvantages.




To ascertain this, the present invention essentially employs a device having a horizontal panel having a generally rectangular configuration. The horizontal panel is defined by a planar upper surface, a planar lower surface, opposed short end walls, and opposed long side walls. A pair of vertical panels are secured to and extend upwardly from the horizontal panel. Each of the vertical panels have a generally rectangular configuration. The vertical panels are defined by planar inner and outer surfaces, short opposed end walls, and long opposed end walls. Lower end walls of the vertical panels are secured to the opposed long side walls of the horizontal panel to define a receiving channel to receive a package between the vertical panels. An abrasive sheet having a series of conically shaped projections is secured to the planar upper surface of the horizontal panel in between the pair of vertical panels.




There has thus been outlined, rather broadly, the more important features of the invention in order than the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

Specifically, it will be noted in the various Figures that the invention employs a device for removing the plastic wrapper from a package for access to the contents of the package, wherein the device is used in accordance with the present invention to accomplish removal of the plastic wrapper from the package. In a broad context, the device consists of a horizontal panel, a pair of vertical panels, and an abrasive surface between the vertical panels. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. Preferably, the horizontal panel


12


is fabricated from plastic.




The horizontal panel


12


has a generally rectangular configuration. The horizontal panel


12


is defined by a planar upper surface, a planar lower surface, opposed short end walls, and opposed long side walls.




The pair of vertical panels


14


are secured to and extend upwardly from the horizontal panel


12


. Each of the vertical panels


14


have a generally rectangular configuration. The vertical panels


14


are defined by planar inner and outer surfaces, short opposed end walls, and long opposed end walls. Lower end walls of the vertical panels


14


are secured to the opposed long side walls of the horizontal panel


12


to define a receiving channel


16


for receiving a package


18


between the vertical panels.




The horizontal panel


12


has an abrasive surface, wherein an abrasive sheet


20


is secured to the planar upper surface of the horizontal panel


12


between the pair of vertical panels


14


. In use, the package


18


is placed within the receiving channel


16


and engaged with the abrasive surface, and is slid along the abrasive surface formed by the abrasive sheet


20


so that the plastic wrapper


22


on the package


18


is broken and torn away from the package


18


by friction and the cutting action of the abrasive sheet


20


. Thus, once the plastic wrapper


22


is cut, the rest of the plastic wrapper can be easily removed from the package


18


manually by the user. Sheet


20


comprises a metal sheet, or layer, secured to the planar upper surface of horizontal panel


12


and has a plurality of conically shaped projections


21


formed therein. Projections


21


are preferably formed by conventional punching techniques, the punching operation being initiated from the bottom surface of sheet


20


and completed before being completely punched through. The height of each projection


21


is in the range between 0.007 inches to about 0.008 inches; the spacing between each projection is approximately 0.1875 inches.




The specific dimensions and physical characteristics of the projections


21


are selected such that the packaging is removed without cutting or otherwise injuring the hands of a user. An abrasive sheet


20


, having five rows, each row having eleven projections


21


, has been successfully utilized.




A second embodiment of the present invention is shown in FIG.

and includes substantially all of the components of the present invention shown in

FIGS. 1-3

except that the vertical panels


14


have been removed and all that comprises the device


10


is the horizontal panel


12


and the abrasive sheet


20


. This will allow the device


10


to be used on varying sized packages that are not dimensioned for being received between the vertical walls


14


in the preferred embodiment.




The present invention can be constructed in various sizes so that a hand held device


10


can be used as well as a larger version that can be placed on a table top for commercial uses.




As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.




With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.




Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
