Abstract

A lubricant carrier is thin and sheet-like and comprises a body with at least one associated lubricant containing container. In one embodiment the body is defined by a pair of sheets and a the container is located between the sheets. The container extends across a width of the body from side-to-side. In use, the carrier is fed into a cutting element of a shredding device. The container is cut, releasing lubricant into direct contact with the cutting element. The remaining portion of the body when fed through the cutting element absorbs excess lubricant.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to shredding devices and, more particularly, methods of lubricating the cutting element of such a device. BACKGROUND OF THE INVENTION

[0002] Paper shredders have long been used in business and government offices to shred documents to maintain the security of information. These shredders are often large industrial type shredders capable of shredding thousands of pages of documents per hour.

[0003] In recent years, identity theft has become a significant problem, and small shredders have been developed and become popular for personal use. These shredders are generally portable and relatively inexpensive.

[0004] Regardless of their application, paper shredders are generally of two types: strip cut and cross-cut. Both types of shredders employ a cutting element. Paper or other material is fed into the cutting element. Strip cut shredders cut the paper into long, thin strips, such as ¼″ or ⅛″ wide strips. Cross-cut shredders cut...

Embodiment Construction

[0024] The invention is a method and apparatus for lubricating a cutting element of a shredding device. In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.

[0025] In general, the invention is a lubricant carrier. The carrier comprises a body which contains lubricant or supports one or more lubricant bearing containers. In a method of use, the carrier is fed into the cutting element of the shredding device. The blades or other cutting elements of the cutting head release the lubricant from the carrier, lubricating the cutting element / head.

[0026]FIGS. 2 and 3 illustrate a preferred embodiment of the invention. FIG. 2 illustrates a lubricant carrier 20. Th...
