Abstract

A holder for an aerosol canister. The holder has a housing and a cap. The cap receives the valve stem of the canister and when depressed will discharge the contents of the canister at a discharge nozzle in the cap. An annular locking ring has a projection which in one position prevents the cup from being pressed downwardly relative to the housing.

Claims

1. A dispenser for dispensing a pressurized fluid comprising:

a canister of pressurized fluid having a discharge nozzle, a cylindrical side wall and a bottom wall;

actuator means releasably connected to said nozzle; and

housing means having a bottom wall and sidewalls integral therewith defining an interior compartment for substantially enclosing said canister, said housing means being in sliding contact with said actuator means.

2. A dispenser according to claim 1, including locking means for locking said actuator means relative to said housing means.

3. A dispenser according to claim 2, wherein said locking means comprises a tab movable between a first position for allowing said actuator means to move relative to said housing means and a second position for preventing said actuator means from moving relative to said housing means, said tab being movable independently of said actuator means and said housing means.

4. A dispenser according to claim 2, wherein said housing means includes at least one of said sidewalls having a slot therein and said locking means comprises a locking ring having a tab extending therefrom, said ring being rotatable between a first position wherein said tab is aligned with said slot and a second position wherein said tab is offset from said slot, said locking ring being movable independently of said actuator means and said housing means.

5. A dispenser according to claim 1, further including means for releasably connecting said actuator means to said housing means.

6. A dispenser to claim 5, wherein said housing means comprises a casing, said actuator means comprises a body portion having at least one leg depending therefrom for slidably engaging said casing, and said interior compartment having a top opening for receiving said canister and said at least one leg.

7. A dispenser according to claim 1, wherein said bottom wall of said canister rests on said bottom wall of said housing means.

8. A dispenser for dispensing a pressurized fluid comprising:

a canister of pressurized fluid having a discharge nozzle and including a cylindrical side wall;

actuator means releasably connected to said nozzle and including at least one leg disposed adjacent to said side wall; and

,

housing means for receiving said canister, said housing means being in sliding contact with said actuator means.

9. A dispenser for dispensing a pressurized fluid comprising:

a canister of pressurized fluid having a discharge nozzle and including a cylindrical side wall;

housing means for receiving said canister;

actuator means releasably connected to said nozzle and including at least one leg disposed adjacent to said side wall, wherein said at least one leg is received within said housing means for sliding engagement therewith; and

said housing means being in sliding contact with said actuator means.

10. A personal protection device comprising:

a canister containing a fluid under pressure, said canister including a nozzle through which said fluid can be discharged;

a first housing element connected to said nozzle; and

a second housing element including an interior compartment for substantially containing said canister and being releasably connected to said first housing element for reciprocating movement therewith;

whereby moving first housing element relative to said second housing element causes said fluid to be dispensed.

11. A device according to claim 10, wherein said first housing element includes leg portions adapted to be received by said second housing element.

12. A device according to claim 11, wherein at least one of said leg portions includes limiting means for limiting reciprocating movement between said at least one leg and said second housing element.

13. A device according to claim 10, further including locking means for preventing relative movement between said first housing element and said second housing element.

14. A personal protection device according to claim 10, wherein said canister includes a cylindrical side wall and a bottom wall and said second housing element includes a bottom wall for supportably engaging said bottom wall of said canister.

15. A dispenser for an aerosol container of the type having a canister with a valve-actuated discharge mechanism, said dispenser comprising:

a housing defining an interior compartment having an open end adapted to receive said canister, said housing having an exterior surface adapted to be grasped by the user; and

a cap positioned at said open end of said housing and slidably connected thereto, moveable between first and second positions relative to said housing, said cap defining an area receiving at least a part of said discharge mechanism and defining a passageway communicating with said discharge mechanism and terminating at a nozzle whereby movement of said cap to said second position will cause the contents of said canister to be released to said passageway.

16. The dispenser of claim 15, further including locking means associated with said cap, said locking means moveable between first and second positions, said first position preventing relative movement between said housing and cap and said second position permitting relative movement between said housing and cap.

17. The dispenser of claim 16, wherein the outer surfaces of said housing are formed as a grip having opposite sides which are generally convex.

18. A dispenser for dispensing a fluid comprising a pressurized canister of fluid having a top wall and a valve stem extending through said top wall, said valve stem being moveable between a high position and a low position relative to said top wall wherein fluid is dispensed through said stem in said low position, the improvement comprising:

a cap having a nozzle, said cap connected to said valve stem and defining an interior passageway terminating at said nozzle for directing said fluid from said stem to said nozzle; and

housing means slidably engaging said cap and containing said canister;

whereby sliding said cap and said housing means toward one another moves said valve stem into said low position.

19. A dispenser for dispensing a pressurized fluid comprising:

a canister of pressurized fluid having a bottom end and a top end having a discharge nozzle;

actuator means connected to said nozzle; and

housing means having a closed bottom and an open top for receiving said bottom end of said canister, said housing means slidably engaging said actuator means.
