Abstract
Abstract Valve means for an aerosol container in which upstanding resilient members are provided to contact a lateral wall portion of a cupped flange upon actuation of the valve means such that the cupped flange will more rapidly be returned to a position closing the aerosol container against egress of its contents.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
254 words
A valve arrangement for releasing a liquid or semi-liquid from a capped container under the influence of a propellant, comprising a laterally displaceable discharge tube extending through the cap of said container and projecting outwardly therefrom, said discharge tube having an end interiorly of said container; a cupped flange at said end having an edge and a lateral wall portion; a shell molded from plastic material surrounding said cupped flange; a sealing disc in said cap; first resilient means resiliently holding said edge in sealing engagement with said sealing disc by applying pressure to said cupped flange in axial direction thereof, whereby lateral displacement of said discharge tube by finger pressure on the outwardly proportion thereof causes said cupped flange to be displaced from said sealing disc to thereby open the valve and permit egress of the substance in said container through said discharge tube, and release of said finger pressure causes sealing engagement between said cupped flange and said sealing disc to be restored to thereby close said valve; second resilient means integrally molded with said first resilient means and said shell and arranged to engage said lateral wall portion, said second resilient means being effective for applying a radially inwardly directed force to said cupped flange upon lateral displacement of said discharge tube, wherby when said finger pressure is released the force exerted by said second resilient means assists in restoring said discharge tube and said cupped flange to their closed position to thereby reduce delay in the closIng of said valve.
Claim 2
Dependent Claim
254 words
A valve arrangement for releasing a liquid or semi-liquid from a capped container under the influence of a propellant, comprising a laterally displaceable discharge tube extending through the cap of said container and projecting outwardly therefrom, said discharge tube having an end interiorly of said container; a cupped flange at said end having an edge and a lateral wall portion; a shell molded from plastic material surrounding said cupped flange; a sealing disc in said cap; first resilient means resiliently holding said edge in sealing engagement with said sealing disc by applying pressure to said cupped flange in axial direction thereof, whereby lateral displacement of said discharge tube by finger pressure on the outwardly proportion thereof causes said cupped flange to be displaced from said sealing disc to thereby open the valve and permit egress of the substance in said container through said discharge tube, and release of said finger pressure causes sealing engagement between said cupped flange and said sealing disc to be restored to thereby close said valve; second resilient means integrally molded with said first resilient means and said shell and arranged to engage said lateral wall portion, said second resilient means being effective for applying a radially inwardly directed force to said cupped flange upon lateral displacement of said discharge tube, wherby when said finger pressure is released the force exerted by said second resilient means assists in restoring said discharge tube and said cupped flange to their closed position to thereby reduce delay in the closIng of said valve.
Claim 3
Dependent Claim
43 words
An arrangement as defined in claim 1, wherein said second resilient means is arranged circumferentially of said cupped flange so as to permit the force exerted by the same to be effective regardless of the direction of lateral displacement of said discharge tube.
Claim 4
Dependent Claim
40 words
An arrangement as defined in claim 1, wherein said second resilient means comprises a plurality of resilient prongs projecting from said shell and located closely adjacent said cupped flange, said prongs being arranged substantially uniformly circumferentially of said cupped flange.
Claim 5
Dependent Claim
19 words
An arrangement as defined in claim 3, wherein said second resilient means comprises 5 to 8 of said prongs.
Claim 6
Dependent Claim
155 words
An arrangement as defined in claim 3, wherein each of said prongs has a fixed end, and a free end spaced from said fixed end, said prongs being deflectable, and said shell having a wall spaced from said prongs in the direction of deflection of the latter, said prongs being arranged relative to said wall in such a manner that upon initial lateral displacement of said discharge tube at least one of said prongs is initially deflected and the free end thereof is displaced in a direction towards but short of said wall so that said one prong acts as a cantilever, and upon further lateral displacement of said discharge tube said one prong is further deflected so that after a predetermined amount of lateral displacement of said discharge tube the free end of said one prong abuts said wall and said one prong is effectively supported at both the fixed and free ends thereof.
