Abstract:
An improved eraser holder on a pencil includes an eraser support band which can be removed in incremental sections to provide access to additional portions of the eraser after the original exposed portion has been worn down. Fracture lines on the band facilitate incremental removal of the sections, and the fracture lines are axially misaligned to strengthen the holder.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to erasers and more particularly pertains to an eraser holder fixedly securable to the end of a writing instrument such as a pencil. 
     2. Description of the Prior Art 
     As is well known in the prior art, a pencil usually provides means for both writing and erasing. More particularly, a wooden pencil usually includes an eraser at one end thereof, and the eraser is contained within a band designed to support its engagement with the pencil. As the eraser wears down however, the band support serves little purpose and eventually, the band prevents access to an additional eraser portion after the eraser has been worn down to a top edge of the band. Unfortunately, no means have been developed to remove the unnecessary portion of the band so as to access additional sections of an eraser contained therein. If such a band could be removed when not needed, possibly in small increments, the possibility of accessing the remaining portion of a pencil eraser could be realized. As such, there appears to be a continuing need for an improved eraser band configuration that would enable a person to use more of the eraser once it has been worn down to the band. In this respect, the present invention substantially addresses this problem. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of eraser holders now present in the prior art, the present invention provides a new eraser holder wherein the same can be utilized to allow ongoing access to an eraser contained therein, while at the same time operating to support a much larger eraser on a pencil. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide an eraser holder and method which has many of the advantages of the eraser holders mentioned heretofore and many additional novel features that result in an eraser holder which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art eraser holders, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises an improved eraser holder on a pencil includes an eraser support band which can be removed in incremental sections to provide access to additional portions of the eraser after the original exposed portion has been worn down. Fracture lines on the band facilitate incremental removal of the sections, and the fracture lines are axially misaligned to strengthen the holder. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that 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 additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     With reference now to the drawings, and in particular to FIGS. 1 and 2 thereof, a new eraser holder embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the eraser holder 10 essentially includes a tubular eraser holder 12 of a metallic construction with an elongated cylindrically-shaped eraser 14 contained therein. The eraser holder 12 includes a bottommost clamping band 16 which facilitates its attachment to a conventional wooden pencil 18 in a well known manner, and the eraser 14 initially extends out of the eraser holder 12 by a predetermined amount which will facilitate its selective use as desired. 
     The elongated tubular eraser holder 12 is provided with a plurality of circumferentially extending scores or fracture lines, each of which is generally designated by the reference numeral 20. These scores 20 are aligned and spaced apart by a predetermined amount. Additionally, each score extends completely around a peripheral surface of the holder 12 and effectively constitutes a weakened area which will allow a fracturing to occur by minimal manual pressure. 
     The eraser holder 12 further includes a plurality of axially aligned scores, each of which is generally designated by the reference numeral 22, and no two of which lie on the same axial line. Each axial score 22 extends between a juxtaposed set of scores 20, and they similarly represent lines of selective fracture associated with the eraser holder 12. Inasmuch as all of the scores 20, 22 represent weakened areas to facilitate selective fracture of the eraser holder 12, by misaligning the scores 22 in the illustrated manner, additional strength is imparted to the holder 12 whereby an increased length of eraser 14 can be utilized in the holder. 
     FIGS. 3 and 4 of the drawings illustrate both the novelty and utility of the eraser holder 10 which comprises the present invention. In this respect, FIG. 3 illustrates how the eraser 14 will eventually be worn down so as to be in a close abutting relationship with a top edge 24 of the holder 12. This is the situation that is typically encountered with conventional pencils 18, i.e., once the eraser 14 reaches the top edge 24 of a holder 12, the rest of the eraser contained within the holder is no longer accessible or usable. 
     FIG. 4 illustrates how the score lines 20, 22 facilitate access to additional portions of the eraser 14 once it has been worn down to a top edge 24. In this respect, a user can insert his fingernail between the top edge 24 of the holder 12 and the eraser 14, and in the vicinity of the topmost axial score 22. With minimal finger pressure then, the score 22 will fracture, and a topmost strip 26 of the holder 12 can be peeled off in the illustrated manner. The removal of the top strip 26 is accomplished by the subsequent fracturing of the first circumferential score 20 and as shown, an additional portion of the eraser 14 is thus exposed for use. Once this additional portion of the eraser 14 is worn down to a new top edge 24, an additional strip 26 of holder 12 can be peeled off to reveal even more of the eraser. Accordingly, depending upon the number of circumferential scores 20, virtually all of an eraser 14 within a holder 12 can be accessed, thereby to eliminate the normal wastage of erasers concealed within holders on conventional pencils 18. 
     As to a further discussion of 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 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 modifications 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 modifications and equivalents may be resorted to, falling within the scope of the invention.
