Abstract
Abstract A device for use in connection with a hair rinsing procedure is disclosed herein having an inner and an outer shell nested together in conformal spaced apart relationship separated by movable water dispensing elements disposed in holes provided in the inner shell. Each element includes a tapered conical portion having several grooves for conducting water through each inner shell hole into a common rinsing cavity. Each water dispensing element carries resilient legs bearing against the outer shell urging the tapered conical portion into each respective hole and is further provided with a stop adapted to engage with the outer shell when the element is depressed. A pressurized water source is detachable coupled to the outer shell for introducing water into a channel between opposing surfaces of the inner and outer shells while the inner and outer shells include coaxially disposed drainage apertures for conducting waste rinse water into a basin.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A hair rinsing device removably situated in a conventional sink basin comprising: a pair of substantially hemispherical shells of conformal configuration nested together in spaced apart relationship to define a fluid passageway between opposing surfaces of said pair of shells; said pair of shells constituting an inner and outer shell having terminating edges joined to establish said passageway; said inner shell of said pair having a multiplicity of openings communicating said fluid passageway with a rinsing cavity of said inner shell; and a plurality of fluid dispersing elements movably disposed in said passageway between said shells and having a grooved conical portion disposed in said inner shell opening, respectively, for discharging fluid carried in said passageway therethrough into said rinsing cavity.
Claim 2
Dependent Claim
121 words
A hair rinsing device removably situated in a conventional sink basin comprising: a pair of substantially hemispherical shells of conformal configuration nested together in spaced apart relationship to define a fluid passageway between opposing surfaces of said pair of shells; said pair of shells constituting an inner and outer shell having terminating edges joined to establish said passageway; said inner shell of said pair having a multiplicity of openings communicating said fluid passageway with a rinsing cavity of said inner shell; and a plurality of fluid dispersing elements movably disposed in said passageway between said shells and having a grooved conical portion disposed in said inner shell opening, respectively, for discharging fluid carried in said passageway therethrough into said rinsing cavity.
Claim 3
Dependent Claim
26 words
The invention as defined in claim 1, including: drainage means carried on said device conducting fluid from said rinse cavity exteriorly of said pair of shells.
Claim 4
Dependent Claim
66 words
The invention as defined in claim 2 wherein each of said fluid dispersing elements includes: a circular body separating said conical portion from at least a pair of resilient outwardly radiating legs; said conical portion adapted to substantially occupy its respective opening and seated in abutment against the circular edge of said opening; and said resilient legs slidably bearing against the surface of said outer shell.
Claim 5
Dependent Claim
25 words
The invention as defined in claim 3 including: stop means carried on said body surrounded by said legs in spaced relationship to said outer shell.
Claim 6
Dependent Claim
23 words
The invention as defined in claim 4 including: an inlet provided in said outer shell for introducing pressurized water to said fluid passageway.
Claim 7
Dependent Claim
41 words
The invention as defined in claim 5 wherein: said shells are rigid and include edge margin connecting means joining the adjacent edge marginal areas of said shell together wherein said connecting means establish the spacing between opposing surfaces of said shells.
Claim 8
Dependent Claim
35 words
The invention as defined in claim 6 wherein: said conformal shells include an angular edge extending along the lower portion of said shells cooperating with said drainage means for draining said inner shell rinse cavity.
Claim 9
Dependent Claim
46 words
A water dispersement element comprising: a circular body terminating at one end in a frusta-conical portion provided with grooves along the tapered conical portion adapted to conduct pressurized water therealong and a plurality of resilient mounting legs outwardly radiating from the opposite end of said body.
Claim 10
Dependent Claim
46 words
A water dispersement element comprising: a circular body terminating at one end in a frusta-conical portion provided with grooves along the tapered conical portion adapted to conduct pressurized water therealong and a plurality of resilient mounting legs outwardly radiating from the opposite end of said body.
