Abstract
An applicator pad (20) for use with a polishing composition for removing scratches or other imperfections from plastic surfaces is disclosed which is generally tubular in shape, and has a bore (22) therethrough to receive the finger of a user. The circumference of the pad is provided with a plurality of substantially flat working surfaces (24). The presently preferred embodiment is about two inches long, and has a hexagonal cross-section. Other preferred embodiments have a differing number of sides. The method of the invention is directed to removal of scratches from plastic surfaces through application of a suitable polishing composition to a pad and moving the pad across scratches or other imperfections to be removed. Among materials suitable for repair using the methods and apparatus of the present invention include eyeglasses, watch crystals, gauge faces, and compact discs.
Claims
1. A pad system as defined in claim 8, wherein the plurality of substantially flat faces consists of six faces.
2. A pad system as defined in claim 1, wherein each of the six faces of said pad means have substantially the same dimensions so that the tubular pad means is substantially hexagonal in cross-section.
3. A pad system as defined in claim 8, wherein the length of the pad means is about two inches.
4. A pad system as defined in claim 1, wherein the length of the pad means is about two inches.
5. A pad system as defined in claim 8, wherein the bore runs axially through the entire length of the pad means so that either end of the pad may be inserted over the user's finger.
6. A pad system as defined in claim 1, wherein the bore runs axially through the entire length of the pad means so that either end of the pad may be inserted over the user's finger.
7. A pad system as defined in claim 8, wherein said pad means is constructed of open cell polyurethane.
8. A pad system for use in removing scratches from plastic surfaces comprising, pad means for use in applying a suitable polishing composition to the surface of a plastic surface, said pad means being formed in a generally tubular shape from an open cell material which is resilient but provides mechanical opposition to compression during use; said tubular shaped pad means including a bore running axially from one end of said pad means through at least a portion of the length of said pad means; said bore having a diameter approximately the same diameter as the diameter of a finger of a user so a user may insert a finger into the bore in order to removably secure the pad means to a user' s finger; and the circumferential surface of said generally tubular pad means being formed of a plurality of substantially flat faces, each of said faces being individually capable of receiving polishing composition and used in removing scratches or other imperfections from plastic surfaces.
9. A pad system as defined in Claim 8, wherein the plurality of substantially flat faces consists of four faces.
10. A pad system as defined in Claim 8, wherein the plurality of substantially flat faces consists of three faces.
11. A pad system as defined in Claim 8, further comprising protection means for protecting the finger of a user from contact with a polishing composition.
12. A pad system as defined in Claim 11, wherein the protection means comprises a sheath which is sized to closely fit over the end of a user's finger before said finger is inserted into the bore, thereby providing a barrier between polishing composition and a user's finger.
13. A pad system as defined in Claim 11, wherein the protection means comprises a tubular member having a length and diameter substantially the same as the bore.
