Abstract
A device for pressurizing an aerosol can (11) in order to refill it with propellant gas (10) comprises a housing (12) containing an air compressor (14) which consists of a cylinder (15), a driving motor (16) and a plunger, a filling nozzle (18) for injecting pressurized air into the aerosol can, a mechanism for activating said compressor when a can is fitted to the filling nozzle, and a mechanism for deactivating said compressor when the air injected into the can reaches a predetermined pressure. A coupling member is provided for coupling the device and the aerosol can when the latter is positioned in a seating (17).
Claims11
An aerosol can for use with a device for pressurizing said aerosol can, said device comprising a housing (12) including an air compressor, for supplying pressurized air, and a seat (17) for supporting an aerosol can;
- a mechanism for activating and deactivating said air compressor;
- and a mechanism for releasably coupling said aerosol can with said air compressor so that said air compressor supplies pressurized air to said aerosol can, said mechanism for releasably coupling said aerosol can with said air compressor cooperating with said mechanism for activating and deactivating said air compressor to activate said air compressor when said aerosol can is positioned on said seat (17), and to deactivate said air compressor when air pressure inside said aerosol can (11) reaches a predetermined pressure level, and said mechanism for releasably coupling said aerosol can with said air compressor including a lever mechanism (32), engagable with said aerosol can, for maintaining said aerosol can properly positioned on said seat (17) until such time as the air pressure inside said aerosol can reaches the predetermined pressure level;
- said aerosol can comprising an enclosed area for containing an aerosol and air, a spray device communicating with said enclosed area for allowing selective discharge of aerosol and air contained with said aerosol can, a base having means for engaging a filling nozzle supported by said seat, and said base having a fluid control valve for controlling the flow of pressurized air into said aerosol can;
- wherein said base (26) comprises an attachment surface which cooperates with said lever mechanism (32).
A device for pressurizing, with pressurized air, an aerosol can having a flow control valve, said device comprising:
- a housing (12) comprising an air compressor, for supplying pressurized air, and a seat (17) for supporting an aerosol can;
- means for activation of and deactivation of said air compressor;
- and
- means for releasably coupling said aerosol can with said air compressor so that said air compressor supplies pressurized air to said aerosol can, said means for releasably coupling said aerosol can with said air compressor cooperating with said activation and deactivation means for activating said air compressor when said aerosol can is positioned on said seat (17), and deactivating said air compressor when air pressure inside said aerosol can (11) reaches a predetermined pressure level, and said means for releasably coupling said aerosol can with said air compressor including a lever mechanism (32), engagable with said aerosol can, for maintaining said aerosol can properly positioned on said seat (17) until such time as the air pressure inside said aerosol can reaches the predetermined pressure level;
- wherein said lever mechanism (32) is at least partially housed within an inclined groove (34) located within said housing, and said inclined groove contains a pressure spring (35) biasing said lever mechanism toward an extend first position in which a stop member (36) limits displacement of said lever mechanism.
A device for pressurizing, with pressurized air, an aerosol can having a flow control valve, said device comprising:
- a housing (12) comprising an air compressor, for supplying pressurized air, and a seat (17) for supporting an aerosol can;
- means for activation of and deactivation of said air compressor;
- and
- means for releasably coupling said aerosol can with said air compressor so that said air compressor supplies pressurized air to said aerosol can, said means for releasably coupling said aerosol can with said air compressor cooperating with said activation and deactivation means for activating said air compressor when said aerosol can is positioned on said seat (17), and deactivating said air compressor when air pressure inside said aerosol can (11) reaches a predetermined pressure level, and said means for releasably coupling said aerosol can with said air compressor including a lever mechanism (32), engagable with said aerosol can, for maintaining said aerosol can properly positioned on said seat (17) until such time as the air pressure inside said aerosol can reaches the predetermined pressure level;
- wherein said lever mechanism is movable and cooperates, when said lever mechanism is in a second position, with a switch which activates said air compressor to supply pressurized air to said aerosol can and, when said lever mechanism is in a first position, said switch deactivates said air compressor.
