Aerosol dispenser valve

Claim 2

Aerosol valve assembly comprising a housing and sealing member forming a chamber, a valve member independent of said chamber and disposed in said chamber, an actuating stem unitary with said valve member and extending through an opening in said sealing member outwardly from said assembly, and a plurality of fingers unitary with said valve member and extending radially outwardly from said valve member toward an annular wall of said housing but removed from said annular wall, said fingers further being inclined axially toward a plate portion of said housing and slidably bearing against said plate portion to urge said valve member into engagement with said sealing member, said fingers being yieldable to permit removal of said valve member from said sealing means upon application of pressure upon said stem but operation upon release of said pressure to urge said valve member back into engagement with said sealing member.

Claim 3

The invention according to claim 1 in which the free ends of said fingers are slidable upon the chamber surface of said plate portion.

Claim 4

Aerosol valve assembly comprising a housing including a plate portion bounded by peripheral annular wall upstanding from only one side thereof, a sealing member disposed adjacent an edge of said annular wall to form a chamber, cover means holding said sealing member in abutting relationship with said annular wall, a nozzle extending outwardly from said plate portion and having an inlet passage in communication with said chamber, said sealing member having an opening therein, an actuating stem disposed in said opening and having a first end extending into said chamber and having a second end extending outwardly beyond said cover, said actuating stem having a discharge passage in communication with the atmosphere, a valve member disposed on and closing the first end of said stem and movably disposed in said chamber, said valve member having an annular recess about said stem formed by a second annular wall upstanding from said valve member and engageable with said sealing member to interrupt communication between said annular recess and said chamber, said stem having an orifice placing said annular groove in communication with said discharge passage, and leaf spring means being a unitary part of said valve member and extending radially therefrom and inclined axially therefrom in a direction toward said plate portion, said spring means bearing against the chamber surface of said plate portion to urge said second annular wall into engagement with said sealing member, said spring means being slidably yieldable upon application of pressure on said stem to permit said second annular wall means to be removed from said sealing member to establish communication between said chamber and said discharge passage and acting upon release of said pressure to urge said second annular wall back into engagement with said sealing member.

Claim 5

Aerosol valve assembly comprising a housing including a plate portion bounded by peripheral annular wall upstanding from only one side thereof, a sealing member disposed adjacent an edge of said annular wall to form a chamber, cover means holding said sealing member in abutting relationship with said annular wall, a nozzle extending outwardly from said plate portion and having an inlet passage in communication with said chamber, said sealing member having an opening therein, an actuating stem disposed in said opening and having a first end extending into said chamber and having a second end extending outwardly beyond said cover, said actuating stem having a discharge passage in communication with the atmosphere, a valve member disposed on and closing the first end of said stem and movably disposed in said chamber, said valve member having an annular recess about said stem formed by a second annular wall upstanding from said valve member and engageable with said sealing member to interrupt communication between said annular recess and said chamber, said stem having an orifice placing said annular groove in communication with said discharge passage, and leaf spring means being a unitary part of said valve member and extending radially therefrom and inclined axially therefrom in a direction toward said plate portion, said spring means bearing against the chamber surface of said plate portion to urge said second annular wall into engagement with said sealing member, said spring means being slidably yieldable upon application of pressure on said stem to permit said second annular wall means to be removed from said sealing member to establish communication between said chamber and said discharge passage and acting upon release of said pressure to urge said second annular wall back into engagement with said sealing member.

Claim 6

The invention according to claim 3 in which said leaf spring means comprise a plurality of fingers extending radially outwardly beyond said second annular wall but short of said housing annular wall.

Claim 7

The invention according to claim 3 in which said leaf spring means comprise a plurality of fingers unitary at their bases with said valve member and otherwise unattached to each other.

Claim 8

The invention according to claim 5 in which the free ends of said fingers are slidable upon said chamber surface of said plate portion.
