System and Method for Timer Actuation of Aerosol Canisters

Abstract

An assembly and method for time delay actuation of a spray canister is provided whereby said time delay for actuation is selected by a user.

I claim: 
     
         1 . An assembly to be affixed to an aerosol canister said assembly comprising:
 a timer mechanism;   a timer ring and cam assembly operatively associated with said timer mechanism said assembly constructed and arranged to be affixed on the top of an aerosol canister, said mechanism further constructed with a first configuration whereby a spray head of said canister is un-actuated in said first configuration, and a second configuration operatively associated with said time in which said assembly actuates said spray head;   an on off cam recess incorporated with said timer ring and cam assembly;   wherein said timer ring and cam assembly and said cam recess are constructed and arranged to actuate an aerosol spray head of an aerosol canister at a user determined time.   
     
     
         2 . The system of  claim 1  where said timer ring and cam assembly has disposed thereon indicia related to the delayed actuation of an aerosol spray head. 
     
     
         3 . The assembly of  claim 1  wherein said cam recess is constructed and arranged to actuate said aerosol spray head at a time congruous with a start position indicated on said timer ring and cam assembly. 
     
     
         4 . The system of  claim 1  where said timer ring and cam assembly is removably attached to said canister. 
     
     
         5 . The system of  claim 1  where said timer ring and cam assembly is fixedly attached to said canister. 
     
     
         6 . A method of actuating an aerosol canister, said method comprising:
 selecting a canister;   providing an assembly according to  claim 1 ;   affixing said assembly to the top of said canister, wherein said affixing includes affixing said assembly in said un-actuated configuration;   selecting a time period in which said assembly will actuate said spray head and setting said timer in accordance with said selected time;   placing said canister with said assembly in a desired position for actuation;   allowing said timer to function until said timer reaches said selected time;   actuating said spray head with said assembly.   
     
     
         7 . The method of  claim 6  wherein said affixing is a removable affixing.
