Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
A metering aerosol actuator assembly adaptable for use with an aerosol system including container means, and valve means mounted within said container means through which aerosol formulation stored within said container means may be dispensed, said actuator comprising first and second interfitting members defining a first and a second chamber and movable relative to each other between a first and a second position, said members being configured and arranged to move from said first to said second relative position upon application thereto of a downwardly directed force, dispensing flow means defined by said members, means for effecting aerosol formulation flow from said valve means into said first chamBer, and means blocking flow communication between said first and second chambers when said members are in said second position and permitting communication therebetween when said members are in said first position, said dispensing flow means effecting flow between said second chamber and the outer atmosphere when said members are in said second position and blocking said flow when said members are in said first position.
Claim 2
Dependent Claim
173 words
A metering aerosol actuator assembly adaptable for use with an aerosol system including container means, and valve means mounted within said container means through which aerosol formulation stored within said container means may be dispensed, said actuator comprising first and second interfitting members defining a first and a second chamber and movable relative to each other between a first and a second position, said members being configured and arranged to move from said first to said second relative position upon application thereto of a downwardly directed force, dispensing flow means defined by said members, means for effecting aerosol formulation flow from said valve means into said first chamBer, and means blocking flow communication between said first and second chambers when said members are in said second position and permitting communication therebetween when said members are in said first position, said dispensing flow means effecting flow between said second chamber and the outer atmosphere when said members are in said second position and blocking said flow when said members are in said first position.
Claim 3
Dependent Claim
19 words
An actuator assembly according to claim 1 comprising spring means biasing said interfitting members to said first relative position.
Claim 4
Dependent Claim
58 words
An actuator assembly according to claim 1 wherein said dispensing flow means comprise orifice means defined in said first and second members and positioned to be misaligned when said members are in said first relative position thereby preventing flow therethrough, and to be aligned when said members are in said second relative position thereby to enable flow therethrough.
Claim 5
Dependent Claim
72 words
An actuator assembly according to claim 1 wherein said dispensing flow means comprises orifice means defined in one of said interfitting members with blocking means defined by the other of said members, said orifice means being exposed to said second chamber when said members are in said second relative position, said blocking means being positioned to block flow through said orifice means when said interfitting members are in said first relative position.
Claim 6
Dependent Claim
78 words
An actuator assembly according to claim 1 wherein said valve means include stem means actuated between a dispensing and nondispensing position, said assembly comprising means mounting said interfitting members in connection with said stem means to enable actuation of said stem means to said dispensing position only when said interfitting members are in said second relative position and to enable said stem means to return to said nondispensing position when said members are in said first relative position.
Claim 7
Dependent Claim
40 words
An actuator assembly according to claim 5 wherein said interfitting members are arranged to transmit a force actuating said stem means to said dispensing position, said force transmission being enabled only while said members are in said second relative position.
Claim 8
Dependent Claim
44 words
An actuator assembly according to claim 6 comprising spring means biasing said interfitting members to said first relative position, said spring means being constructed to permit movement of said members to said second relative position prior to commencement of actuation of said stem means.
Claim 9
Dependent Claim
63 words
An actuator assembly according to claim 1 wherein said first and second members generally comprise a cup-shaped configuration with each having radially spaced inner and outer cylindrical walls, said members being interfitted with said inner and outer walls, respectively, overlapping, said first chamber being defined by and within said inner walls and said second chamber being defined between said inner and outer walls.
Claim 10
Dependent Claim
53 words
An actuator assembly according to claim 8 wherein said first interfitting member is fixedly mounted upon said stem means and said second interfitting member is relatively movable with respect thereto, with downward depression of said second member being operable to move said members from said first relative position to said second relative position.
