Abstract
Abstract An aerosol dispenser comprises a can closed by a cup-like cap member, a valve body supported on the cap member, and a manually operable push button adapted when depressed to dispense the aerosol. Outward movement of the push button is limited by means such as a cover, and one of the can and cap member include a part which when subjected to an internal pressure above a safe value deforms and moves outwards together with the valve body, thereby depressing the push button to dispense the aerosol as for normal operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
An aerosol dispenser comprising, a can, a valve on said can having a manually operable actuator accessible from exteriorly of said can to dispense a pressurized pressure fluid in the can, a cap member mounting said valve on said can, pressure-responsive deformable means on said can and deformable in a direction outwardly of the can and for moving said valve relative to said can and actuating it when a predetermined pressure in said can is exceeded, a can cover secured on said can having means engaged by said actuator when said deformable means moves said valve to actuate said valve to dispense said pressure fluid, and said deformable means comprising a part of said can intermediate a region where said cover is secured to said can and said cap member is secured to said can.
Claim 2
Dependent Claim
135 words
An aerosol dispenser comprising, a can, a valve on said can having a manually operable actuator accessible from exteriorly of said can to dispense a pressurized pressure fluid in the can, a cap member mounting said valve on said can, pressure-responsive deformable means on said can and deformable in a direction outwardly of the can and for moving said valve relative to said can and actuating it when a predetermined pressure in said can is exceeded, a can cover secured on said can having means engaged by said actuator when said deformable means moves said valve to actuate said valve to dispense said pressure fluid, and said deformable means comprising a part of said can intermediate a region where said cover is secured to said can and said cap member is secured to said can.
Claim 3
Dependent Claim
23 words
An aerosol dispenser according to claim 1, in which said deformable means is generally tubular and comprises at least one flexible peripheral fold.
Claim 4
Dependent Claim
20 words
An aerosol dispenser according to claim 1, in which said cover comprises a removable cover removably secured to said can.
Claim 5
Dependent Claim
150 words
An aerosol dispenser comprising, a can, a valve on said can having a manually depressable actuator accessible from exteriorly of said can to dispense a pressurized fluid in the can, a cap member mounting said valve on said can, said can having a neck and an opening in said neck, said cap member having a protruding circumferential bulge defining a re-entrant groove and holding said cap member in said neck fluidtightly, said cap member having a pressure-responsive, deformable part deformable in a direction outwardly of the can for moving said valve relative to said can and actuating it when a predetermined pressure in said can is exceeded, said actuator comprising a flange disposed in said re-entrant groove limiting travel of said valve and actuating said depressable actuator when said deformable part moves said valve and said actuator flange engages a boundary of said re-entrant groove thereby dispensing said pressure fluid.
Claim 6
Dependent Claim
150 words
An aerosol dispenser comprising, a can, a valve on said can having a manually depressable actuator accessible from exteriorly of said can to dispense a pressurized fluid in the can, a cap member mounting said valve on said can, said can having a neck and an opening in said neck, said cap member having a protruding circumferential bulge defining a re-entrant groove and holding said cap member in said neck fluidtightly, said cap member having a pressure-responsive, deformable part deformable in a direction outwardly of the can for moving said valve relative to said can and actuating it when a predetermined pressure in said can is exceeded, said actuator comprising a flange disposed in said re-entrant groove limiting travel of said valve and actuating said depressable actuator when said deformable part moves said valve and said actuator flange engages a boundary of said re-entrant groove thereby dispensing said pressure fluid.
