Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
204 words
An aerosol valve actuator spray button comprising a body member having an axial cavity open at the bottom and an insert member occupying said cavity, the insert member having an axial bore open at the bottom and having a lower portion adapted to snugly receive the upstanding stem of an aerosol container valve, the upper portion of said bore constituting an expansion chamber in communication with the valve stem, an axial passage of smaller cross-sectional area than that of the expansion chamber extending from the top surface of the insert member to the expansion chamber, a plurality of radial grooves in the top surface of the insert extending from said axial passage, and a groove extending around the periphery of the top surface and intersecting said radial grooves, the body member including a discharge orifice extending from the exterior of the body member to said cavity, a swirl generator depression in the cavity wall proximate to and in communication with said discharge orifice, and at least one groove in the cavity wall extending upwardly from said swirl generator depression and thence diametrically across the top wall of the cavity and in communication with said peripheral groove and said axial passage of the insert member.
Claim 2
Dependent Claim
204 words
An aerosol valve actuator spray button comprising a body member having an axial cavity open at the bottom and an insert member occupying said cavity, the insert member having an axial bore open at the bottom and having a lower portion adapted to snugly receive the upstanding stem of an aerosol container valve, the upper portion of said bore constituting an expansion chamber in communication with the valve stem, an axial passage of smaller cross-sectional area than that of the expansion chamber extending from the top surface of the insert member to the expansion chamber, a plurality of radial grooves in the top surface of the insert extending from said axial passage, and a groove extending around the periphery of the top surface and intersecting said radial grooves, the body member including a discharge orifice extending from the exterior of the body member to said cavity, a swirl generator depression in the cavity wall proximate to and in communication with said discharge orifice, and at least one groove in the cavity wall extending upwardly from said swirl generator depression and thence diametrically across the top wall of the cavity and in communication with said peripheral groove and said axial passage of the insert member.
Claim 3
Dependent Claim
138 words
An aerosol valve actuator spray button comprising a body member having a cavity open at the bottom and an insert member occupying said cavity, the insert member having a valve stem receiving socket open at the bottom, an annular passage encompassing the periphery of the top surface of the insert member, a passage in the insert member extending from said valve stem receiving socket to said annular passage, the body member having a discharge orifice extending from the exterior surface of the body member to said cavity, a swirl generator means in communication with the discharge orifice, said swirl generator means being formed in the surface defining the body member cavity, and a passage formed between the juxtaposed surfaces of the body member cavity and the insert member extending from said annular passage to said swirl generator means.
Claim 4
Dependent Claim
138 words
An aerosol valve actuator spray button comprising a body member having a cavity open at the bottom and an insert member occupying said cavity, the insert member having a valve stem receiving socket open at the bottom, an annular passage encompassing the periphery of the top surface of the insert member, a passage in the insert member extending from said valve stem receiving socket to said annular passage, the body member having a discharge orifice extending from the exterior surface of the body member to said cavity, a swirl generator means in communication with the discharge orifice, said swirl generator means being formed in the surface defining the body member cavity, and a passage formed between the juxtaposed surfaces of the body member cavity and the insert member extending from said annular passage to said swirl generator means.
Claim 5
Dependent Claim
64 words
The actuator of claim 2 wherein the annular passage is formed at the intersecting edge of the top surface of the insert member, and the passage between the annular passage and the valve stem receiving socket being constituted by at least one radial groove Formed in the top surface of the insert member, said groove intersecting an axial aperture in communication with said socket.
Claim 6
Dependent Claim
27 words
The actuator of claim 2 wherein the passage leading to the swirl generator means from the annular passage is a longitudinally disposed groove in said cavity wall.
Claim 7
Dependent Claim
30 words
The actuator of claim 4 wherein said longitudinally disposed groove is an extension of a diametrically disposed groove formed in the top wall of the cavity of the body member.
Claim 8
Dependent Claim
33 words
The actuator of claim 4 wherein the swirl generator means includes a plurality of baffle members which define tangential passages extending from the periphery of the swirl generator means toward the discharge orifice.
Claim 9
Dependent Claim
136 words
A valve actuator spray button for a pressurized container comprising, a body member having a cavity, and an insert member located within said cavity, said insert member being provided with a valve stem receiving socket and provided with at least one product flow passage for communicating with the valve stem and extending to the exterior of the insert member, the juxtaposed surfaces of the insert member and of the cavity of said body member having at least one duct formed therebetween, said duct comprising a groove in one of the members cooperating with the adjacent surface of the other member to complete said duct which extends from the product flow passage of the insert member to a swirl generating means including a swirl chamber formed as a depression in the surface of the body member cavity.
Claim 10
Dependent Claim
136 words
A valve actuator spray button for a pressurized container comprising, a body member having a cavity, and an insert member located within said cavity, said insert member being provided with a valve stem receiving socket and provided with at least one product flow passage for communicating with the valve stem and extending to the exterior of the insert member, the juxtaposed surfaces of the insert member and of the cavity of said body member having at least one duct formed therebetween, said duct comprising a groove in one of the members cooperating with the adjacent surface of the other member to complete said duct which extends from the product flow passage of the insert member to a swirl generating means including a swirl chamber formed as a depression in the surface of the body member cavity.
