Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A fingernail cleaning apparatus comprising: a housing with a bottom and an aperture above the bottom for inserting a finger; a pump mounted on the housing having an intake port connecting the pump to the housing near the bottom thereof for the intake of liquid from the housing and a discharge port for the discharge of liquid from the pump; a nozzle member connected to the discharge port having a discharge orifice located inwardly from the housing aperture; and a pointed projection disposed within the orifice oriented generally parallel to the flow of liquid through the orifice for pushing the skin near the fingertip away from the fingernail when the fingertip is pressed against the nozzle member to provide access for liquid issuing from the orifice to a space behind the fingernail without affecting the directionality of liquid issuing from the orifice so as to affect a complete cleaning of the space.
