Abstract

Abstract Disclosed is a method of filing a synthetic nail comprising rubbing the nail with a unique device that captures dust produced by filing. The device includes an elongated, rigid, support member having a generally flat, planar support surface. A foam strip is attached to the planar surface of the rigid support member and it has a generally flat, planar, tacky support surface. An abrasive member is bonded to the planar support surface of the foam strip comprising a crisscrossed arrangement of spaced apart, thread-like filaments having gritty abrasive material embedded therein. The crisscross arrangement of filaments forms a plurality of cavities open at the surface of the abrasive member to collect and hold therein nail dust produced upon rubbing the abrasive member against a nail.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 59 words
A device for filing nails, including an elongated, rigid, support member having support surface, and an abrasive member bonded to the support surface having a plurality of cavities therein open at the surface of the abrasive member and having an internal tacky surface to which nail dust adheres that is produced upon rubbing the abrasive member against a nail.
Claim 2
Independent Claim 59 words
A device for filing nails, including an elongated, rigid, support member having support surface, and an abrasive member bonded to the support surface having a plurality of cavities therein open at the surface of the abrasive member and having an internal tacky surface to which nail dust adheres that is produced upon rubbing the abrasive member against a nail.
Claim 3
Dependent Claim 30 words

Claim 13
Independent Claim 68 words
A method of filing a synthetic nail comprising rubbing the nail with a device, including an elongated, rigid, support member having support surface, and an abrasive member bonded to the support surface having a plurality of cavities therein open at the surface of the abrasive member and having an internal tacky surface to which nail dust adheres that is produced upon rubbing the abrasive member against a nail.
Claim 14
Independent Claim 68 words
A method of filing a synthetic nail comprising rubbing the nail with a device, including an elongated, rigid, support member having support surface, and an abrasive member bonded to the support surface having a plurality of cavities therein open at the surface of the abrasive member and having an internal tacky surface to which nail dust adheres that is produced upon rubbing the abrasive member against a nail.
Claim 15
Dependent Claim 13 words
The method of claim 11 where the synthetic nail is an acrylic nail.
Claim 16
Dependent Claim 35 words
The method of claim 11 where the support member, foam strip, and abrasive member are made of water resistance materials, and the device is periodically cleaned to remove captured nail dust by rinsing with water.
