Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
187 words
In an aerosol spray container, in combination, a receptacle having one region for a liquid to be sprayed and a communicating other region for a gaseous propellant under pressure; valve chamber means in said receptacle; hollow valve stem means having a nozzle portion outside said receptacle and an end portion in said valve chamber means, said valve stem means being slidable in a fixed path toward and away from a base wall of said valve chamber means; resiliently deflectable means between said wall and valve stem means and subdividing said valve chamber means into a lower and an upper compartment located successively along said path, said end portion located in one of said compartments and bearing upon said resiliently means; biasing means in the other compartment bearing upon said wall and said end portion; first passage means connecting said lower compartment with said gas region; and second passage means connecting the interior of said valve stem means with said liquid region, and third passage means for connecting said compartments with the interior of said valve stem means, in response to movement of the latter towards said wall.
Claim 2
Dependent Claim
187 words

Claim 3
Dependent Claim
35 words
In an aerosol spray container as defined in claim 1, said resiliently deflectable means being deflect-able towards said wall under a predetermined pressure which is greater than the force required for compressing said biasing means.
Claim 4
Dependent Claim
24 words
In an aerosol spray container as defined in claim 2, wherein said biasing means is a sealed bellows whose interior is at atmospheric pressure.
Claim 5
Dependent Claim
64 words
In an aerosol spray container as defined in claim 2, wherein said valve stem means is movable towards said wall to a first operative position in which said third passage means connects said one compartment with said valve stem means, and a second operative position closer to said wall and in which the interior of said valve is connected with both of said regions.
