Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
A personal spray device characterized by a nozzle which issues a liquid jet which is swept in at least one dimension transverse to the nominal jet flow direction, causing said jet to break up into liquid droplets, said device comprising: a body member; an inlet means defined in said body member for receiving liquid under pressure; means for establishing a liquid pressure inside said body member which is greater than ambient pressure; jet-defining means within said body member responsive to the received liquid for forming said liquid jet; an outlet opening defined in said body member for issuing said jet exteriorly of said body member, said outlet opening being elongated in at least said one dimension transverse to the flow direction of said jet therethrough; jet-sweeping means operated solely by the pressure of said liquid and located within said body member for repetitively sweeping said jet in at least said one dimension; and a guard member projecting from said body member and disposed about said outlet opening.
Claim 2
Dependent Claim
167 words
A personal spray device characterized by a nozzle which issues a liquid jet which is swept in at least one dimension transverse to the nominal jet flow direction, causing said jet to break up into liquid droplets, said device comprising: a body member; an inlet means defined in said body member for receiving liquid under pressure; means for establishing a liquid pressure inside said body member which is greater than ambient pressure; jet-defining means within said body member responsive to the received liquid for forming said liquid jet; an outlet opening defined in said body member for issuing said jet exteriorly of said body member, said outlet opening being elongated in at least said one dimension transverse to the flow direction of said jet therethrough; jet-sweeping means operated solely by the pressure of said liquid and located within said body member for repetitively sweeping said jet in at least said one dimension; and a guard member projecting from said body member and disposed about said outlet opening.
Claim 3
Dependent Claim
17 words
The device according to claim 1 wherein said guard member is a wall of cellular foam material.
Claim 4
Dependent Claim
20 words
The device according to claim 2 wherein said wall has a teardrop-shape cross-section taken transverse to the direction of flow.
Claim 5
Dependent Claim
18 words
The device according to claim 1 wherein said jet-sweeping means is a fluid oscillator having no moving parts.
Claim 6
Dependent Claim
21 words
The apparatus according to claim 1 wherein said guard member is made of soft, flexible material which is porous to air.
