Aerosol cap and system for dispensing a fluid from a canister

1. An aerosol cap comprising:

an outer hollow shell that includes at least one rib element; and

an inner hollow shell that is partially enclosed by said outer shell and centrally disposed therein, said inner and outer shells being physically interconnected together by said at least one rib element, said inner hollow shell comprising a base ring member hingedly connected to a pod member, said pod member including a button support for receiving a button actuator of a canister, said pod member further including a cam profile for cooperating with said at least one rib element to transition said aerosol cap between an operative position and a non-operative position upon rotating said outer hollow shell relative to said inner hollow shell;

wherein said outer hollow shell comprises a cylindrical side wall with a spray passage and a finger passage extending therethrough;

wherein said pod member and said base ring member are connected to one another via a flexible hinge that allows said pod member to pivot relative to said base ring member upon application of an axial force to said top end of said pod member;

wherein said base ring member includes a cylindrical side wall having a domed upper portion, and wherein said flexible hinge extends between, and physically connects, said bottom end of said pod member and said domed upper portion.

2. The aerosol cap of claim 1 , wherein said side wall includes oppositely disposed finger depressions to facilitate rotation of said outer hollow shell relative to said inner hollow shell.

3. The aerosol cap of claim 1 , wherein said pod member comprises:

a closed top end;

an open bottom end; and

a cylindrical side wall that includes a side spray aperture;

wherein said cam profile is located at said bottom end of said pod member.

4. The aerosol cap of claim 1 , wherein said flexible hinge and said spray aperture are circumferentially aligned with one another.

5. The aerosol cap of claim 1 , wherein said button support includes three radially spaced apart elongated ribs, each of said elongated ribs extending axially from said top end of said pod member, at least one of said elongated ribs including a fin for mating with a channel of the button actuator.

6. An aerosol cap adapted to mate with a two-piece canister, said aerosol cap comprising:

an outer hollow shell that includes at least one rib element; and

an inner hollow shell that is partially enclosed by said outer shell and centrally disposed therein, said inner and outer shells being physically interconnected together by said at least one rib element, said inner hollow shell including a cam profile for cooperating with said at least one rib element to transition said aerosol cap between an operative position and a non-operative position upon rotating said outer hollow shell relative to said inner hollow shell;

wherein said outer hollow shell comprises a cylindrical side wall with a spray passage and a finger passage extending therethrough;

wherein said pod member comprises a closed top end, an open bottom end, and a cylindrical side wall that includes a side spray aperture;

wherein said cam profile is located at said bottom end of said pod member:,

wherein said pod member and said base ring member are connected to one another via a flexible hinge that allows said pod member to pivot relative to said base ring member upon application of an axial force to said top end of said pod member;

wherein said base ring member includes a cylindrical side wall having a domed upper portion, and wherein said flexible hinge extends between, and physically connects, said bottom end of said pod member and said domed upper portion.

7. The aerosol cap of claim 6 , wherein said side wall includes oppositely disposed finger depressions to facilitate rotation of said outer hollow shell relative to said inner hollow shell.

8. An aerosol cap comprising:

an outer hollow shell that includes at least one rib element; and

an inner hollow shell that is partially enclosed by said outer shell and centrally disposed therein, said inner and outer shells being physically interconnected together by said at least one rib element, said inner hollow shell comprising a base ring member hingedly connected to a pod member, said pod member including a button support for receiving a button actuator of the canister, said pod member further including a cam profile for cooperating with said at least one rib element to transition said aerosol cap between an operative position and a non-operative position upon rotating said outer hollow shell relative to said inner hollow shell;

wherein said outer hollow shell comprises a cylindrical side wall with a spray passage and a finger passage extending therethrough;

wherein said pod member comprises a closed top end, an open bottom end, and a cylindrical side wall that includes a side spray aperture;

wherein said cam profile is located at said bottom end of said pod member;

wherein said base ring member includes a cylindrical side wall having a domed upper portion, said flexible hinge extending between, and connecting, said bottom end of said pod member and said domed upper portion;

wherein said outer hollow shell further comprises a plurality of reinforcement ribs extending radially between an inner surface of a cylindrical side wall and an outer surface of a cylindrical wall;

wherein an upper portion of said base ring member includes two circumferentially spaced apart stop detents that are configured to cooperate with said plurality of reinforcement ribs to securely maintain said aerosol cap in the operative and non-operative positions;

wherein said outer hollow shell partially encloses, and is concentric with, said pod member in both the operative and non-operative positions.
