Abstract
Abstract A fingernail device which includes a receptacle having a small diameter fluid passageway positioned at an angle to the base of the receptacle. The passageway has a nozzle which directs fluid at a downward angle to the upper surface of the base of the receptacle to create a high-velocity, shallow, fan-shaped fluid stream which flows along and substantially parallel to said base in the direction of the finger tips which are in contact with the base in proximity to the nozzle. The receptacle has a depth such that the level of the fluid retained in it during a cleaning operation will develop a head sufficient to eliminate any splashing, spray-out or extreme turbulance of the fluid in the receptacle. Passageway means are provided for entraining a cleansing agent in the fluid stream.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
A fingernail cleaning device, comprising: a receptacle for receiving and maintaining a cleaning fluid at a predetermined level therein, said receptacle having an open top for enabling the fingers of one hand of a user to be placed in the receptacle and a bottom in contact with which the fingertips of said one hand of a user are placed during cleaning of the fingernails; and a small diameter fluid passageway positioned in the receptacle at an acute angle with relation to the bottom of the receptacle, said passageway being in communication with a source of a cleaning fluid and acting to direct cleaning fluid at a downward angle to the bottom of the receptacle to provide a high-velocity, fan-shaped stream of the cleaning fluid which travels along the bottom of the receptacle in the direction of the fingernails of the user, said predetermined level of fluid in the receptacle acting to provide sufficient fluid pressure above said stream to substantially prevent any splashing of fluid from the receptacle by said stream during cleansing of the nails.
Claim 2
Dependent Claim
176 words
A fingernail cleaning device, comprising: a receptacle for receiving and maintaining a cleaning fluid at a predetermined level therein, said receptacle having an open top for enabling the fingers of one hand of a user to be placed in the receptacle and a bottom in contact with which the fingertips of said one hand of a user are placed during cleaning of the fingernails; and a small diameter fluid passageway positioned in the receptacle at an acute angle with relation to the bottom of the receptacle, said passageway being in communication with a source of a cleaning fluid and acting to direct cleaning fluid at a downward angle to the bottom of the receptacle to provide a high-velocity, fan-shaped stream of the cleaning fluid which travels along the bottom of the receptacle in the direction of the fingernails of the user, said predetermined level of fluid in the receptacle acting to provide sufficient fluid pressure above said stream to substantially prevent any splashing of fluid from the receptacle by said stream during cleansing of the nails.
Claim 3
Dependent Claim
49 words
A fingernail cleaning device according to claim 1 wherein cleaning fluid deflector means is positioned in the receptacle, said deflector means cooperating with the fluid pressure due to said predetermined level of cleaning fluid in the receptacle to substantially prevent splashing, or spray-out of cleaning fluid from the receptacle.
Claim 4
Dependent Claim
43 words
A fingernail cleaning device according to claim 1 wherein the receptacle is provided with a flexible conduit, the inlet end of the conduit being provided with adapter and coupling means to enable it to be attached to a faucet or a garden hose.
Claim 5
Dependent Claim
48 words
A fingernail cleaning device according to claim 1 wherein the receptacle is provided with cleaning fluid drain means, said means being located at an elevated position with relation to the bottom of the receptacle to enable said predetermined level of cleaning fluid to be established in the receptacle.
Claim 6
Dependent Claim
34 words
A fingernail cleaning device according to claim 1 wherein the small diameter fluid passageway is positioned at an angle of about 3 to about 35 degrees with relation to the bottom of the receptacle.
Claim 7
Dependent Claim
56 words
A fingernail cleaning device according to claim 1 wherein a restricted passageway intersects the small diameter fluid passageway at a point upstream of said fluid passageway, said restricted passageway being in communication with a source of a cleansing agent which passes through said restricted passageway and is entrained in the fluid passing through said fluid passageway.
