Abstract
Abstract Aerosol valve comprising a socket-shaped body securable to the top of an aerosol container, a stem and elongated flexible arms fast with and integral to the socket-shaped body and the stem. The bottom of the socket-shaped body has a hole, from the lower portion of which a hollow extension projects, on which a drawing tube can be threaded and inserted into the container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
An aeroSol valve securable within the sealed closure top of an aerosol container comprising: a body portion of a general cup-shape having cylindrical outer walls, a circumferential upper free edge, and a bottom integral with said outer walls with a centrally located hole extending through said bottom; a tubular extension integral with said bottom extending from around said hole downwardly from said bottom; at least one elongated resiliently yieldable arm integral with said bottom and extending upwardly from adjacent said hole, said arm having an engaging surface adjacent the upper end; a stem integral with said upper end of said yieldable arm and operable in a vertical direction with said yieldable arm, said stem extending upwardly from said yieldable arm beyond said free edge and having passage means therein; whereby said valve when secured within said closure top is sealed against the inside surface of said closure top adjacent said free edge, said stem projects upwardly through said top, and said engaging surface of said yieldable arm is coupled to said inner surface of said closure top to resiliently deform said yieldable arm downwardly causing said yieldable arm to urge said stem upwardly.
Claim 2
Dependent Claim
193 words
An aeroSol valve securable within the sealed closure top of an aerosol container comprising: a body portion of a general cup-shape having cylindrical outer walls, a circumferential upper free edge, and a bottom integral with said outer walls with a centrally located hole extending through said bottom; a tubular extension integral with said bottom extending from around said hole downwardly from said bottom; at least one elongated resiliently yieldable arm integral with said bottom and extending upwardly from adjacent said hole, said arm having an engaging surface adjacent the upper end; a stem integral with said upper end of said yieldable arm and operable in a vertical direction with said yieldable arm, said stem extending upwardly from said yieldable arm beyond said free edge and having passage means therein; whereby said valve when secured within said closure top is sealed against the inside surface of said closure top adjacent said free edge, said stem projects upwardly through said top, and said engaging surface of said yieldable arm is coupled to said inner surface of said closure top to resiliently deform said yieldable arm downwardly causing said yieldable arm to urge said stem upwardly.
Claim 3
Dependent Claim
52 words
The aerosol valve as claimed in claim 1, wherein said cylindrical outer walls include longitudinal ribs projecting from the inner surface of said walls and extending from said bottom to adjacent said upper free edge, whereby said walls are strengthened to prevent buckling when said valve is installed in said closure top.
Claim 4
Dependent Claim
15 words
The aerosol valve as claimed in claim 1, wherein said valve is made of plastic.
Claim 5
Dependent Claim
29 words
The aerosol valve as claimed in claim 1, including a seal member positioned adjacent said free edge for sealing said valve to said inner surface of said closure top.
Claim 6
Dependent Claim
46 words
The aerosol valve as claimed in claim 1, wherein said stem is tubular and has a bottom wall adjacent said upper end of said yieldable arm, and a hole adjacent said bottom wall extending through the tubular wall of said stem to define said passage means.
Claim 7
Dependent Claim
241 words
An aerosol valve securable within the sealed closure top of an aerosol container comprising: a body portion of a general cup-shape having cylindrical outer walls, a circumferential upper free edge, and a bottom integral with said outer walls with a centrally located hole extending through said bottom; a tubular extension integral with said bottom extending from around said hole downwardly from said bottom; at least one elongated resiliently yieldable arm integral with said bottom and extending upwardly from adjacent said hole, said arm having an engaging surface adjacent the upper end; a stem integral with said upper end of said yieldable arm and operable in a vertical direction with said yieldable arm, said stem extending upwardly from said yieldable arm beyond said free edge and having passage means therein; an annular seal member positioned adjacent said free edge and mounted concentrically around said stem, said seal member sealing said valve to said closure top and providing an operable seal on the inner annular surface of said member between said passage means and the interior of said container; whereby said valve when secured within said closure top is sealed against the inside surface of said closure top adjacent said free edge, said stem projects upwardly through said top, and said engaging surface of said yieldable arm is coupled to said inner surface of said closure top to resiliently deform said yieldable arm downwardly causing said yieldable arm to urge said stem upwardly.
Claim 8
Dependent Claim
241 words
An aerosol valve securable within the sealed closure top of an aerosol container comprising: a body portion of a general cup-shape having cylindrical outer walls, a circumferential upper free edge, and a bottom integral with said outer walls with a centrally located hole extending through said bottom; a tubular extension integral with said bottom extending from around said hole downwardly from said bottom; at least one elongated resiliently yieldable arm integral with said bottom and extending upwardly from adjacent said hole, said arm having an engaging surface adjacent the upper end; a stem integral with said upper end of said yieldable arm and operable in a vertical direction with said yieldable arm, said stem extending upwardly from said yieldable arm beyond said free edge and having passage means therein; an annular seal member positioned adjacent said free edge and mounted concentrically around said stem, said seal member sealing said valve to said closure top and providing an operable seal on the inner annular surface of said member between said passage means and the interior of said container; whereby said valve when secured within said closure top is sealed against the inside surface of said closure top adjacent said free edge, said stem projects upwardly through said top, and said engaging surface of said yieldable arm is coupled to said inner surface of said closure top to resiliently deform said yieldable arm downwardly causing said yieldable arm to urge said stem upwardly.
