Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
A hair rinsing device comprising, a flexible convex outer cover including a central opening defined by a first perimeter rim wherein the outer cover is selectively securable to a flexible convex inner covering including a further central opening defined by a second perimeter rim, and the outer cover formed of a fluid impermeable material with the inner cover formed of a fluid impermeable material and wherein the inner cover further includes a matrix of fluid openings formed in the inner cover spaced from the second rim, and a fluid inlet integrally secured to the outer cover to receive fluid and direct the fluid to the fluid openings of the inner cover, and including a water chamber defined between the inner and outer cover, wherein the inner and outer cover are secured together, and wherein the first rim includes a continuous trapezoidal channel formed within a bottom surface of the first rim, and the second rim includes a trapezoidal rib extending upwardly and orthogonally relative to an upper surface of the second rim to enable the trapezoidal channel to receive the trapezoidal rib for securement of the first and second covers together.
Claim 2
Dependent Claim
191 words
A hair rinsing device comprising, a flexible convex outer cover including a central opening defined by a first perimeter rim wherein the outer cover is selectively securable to a flexible convex inner covering including a further central opening defined by a second perimeter rim, and the outer cover formed of a fluid impermeable material with the inner cover formed of a fluid impermeable material and wherein the inner cover further includes a matrix of fluid openings formed in the inner cover spaced from the second rim, and a fluid inlet integrally secured to the outer cover to receive fluid and direct the fluid to the fluid openings of the inner cover, and including a water chamber defined between the inner and outer cover, wherein the inner and outer cover are secured together, and wherein the first rim includes a continuous trapezoidal channel formed within a bottom surface of the first rim, and the second rim includes a trapezoidal rib extending upwardly and orthogonally relative to an upper surface of the second rim to enable the trapezoidal channel to receive the trapezoidal rib for securement of the first and second covers together.
Claim 3
Dependent Claim
44 words
A hair rinsing device as set forth in claim 1 wherein the second rim further includes a continuous elastomeric sheath laminated to a bottom surface of the second rim, and the sheath further including an elastomeric core captured therein surrounded by the elastomeric sheath.
Claim 4
Dependent Claim
32 words
A hair rinsing device as set forth in claim 2 wherein the fluid openings are defIned by a matrix of through-extending apertures formed throuGhout the inner cover spaced from the second rim.
Claim 5
Dependent Claim
