A sprayer device for storing and combining two discretely separated chemical compositions to form a mixture thereof and to dispense said mixture from said device, said device comprising:
- (a) first and second bottles configured and adapted to contain, respectively, a first and a second chemical composition, said first bottle containing said first composition under a first pressure condition and said second bottle containing said second composition under a second condition, said second pressure being lower than said first pressure and said first and second pressure conditions being respectively maintained by corresponding valves operatively associated with said bottles;
- (b) said corresponding valves comprising a first aerosol valve associated with said first bottle and a second aerosol valve associated with said second bottle, said first and said second aerosol valves inserted within a neck portion of said first and second bottles respectively, in a manner so as to achieve a gas-tight connection therebetween;
- and
- (c) each said first and said second aerosol valves comprising an atomizer configured for insertion within a valve seat portion of a bridge member for connecting said first and said second bottles in operative association, said atomizer thereafter being operated by a downward pressure applied to a body portion of said bridge member to cause said first and said second aerosol valves to open and thus to permit the composition within the corresponding receptacle to exit therefrom and enter a path defined by one of either a longitudinal transfer groove or a distribution duct;
- and
- (d) an elongated cylindrical tube member having a first and a second end, said first end being attached to said first or said second aerosol valve and said second end extending into a corresponding one of said bottles and terminating substantially adjacent to a bottom portion thereof;
- and
- (e) said bridge member forming a liquid-tight connection between said first and said second aerosol valves and comprising:
- (i) said body portion forming a housing which defines first and second valve seats adapted and configured for operatively engaging, respectively, said first and said second aerosol valves, each said valve seat communicating with a corresponding channel extending substantially perpendicularly therefrom to a rotatable key member insertable within a bore defined by said body portion of said bridge member, a vertical axis of both said channels being in substantially parallel alignment;
- and
- (ii) a rotatable key member inserted within said bore defined by said body portion for selecting said path, said key member being rotatable to a first position within said bridge member to allow said first composition to pass out of said first bottle through said first aerosol valve and to enter said second bottle through said second aerosol valve to permit the formation of a mixture therebetween, and thereafter to a second position to permit said mixture to exit said second bottle through said second aerosol valve and to subsequently be dispensed from said device through said spray nozzle, said key member including
- (a) said longitudinal transfer groove configured for simultaneous fluid communication with said first and said second aerosol valves when said key member is aligned at said first position;
- (b) said distribution duct adapted to be in fluid communication at a first end thereof with said second aerosol valve when said key member is rotated to said second position, said distribution duct communicating, at a second end thereof, with said spray nozzle located upon a first terminal portion of said bridge member;
- and
- (c) an operating button located at a second terminal portion of said bridge member, opposite said spray nozzle, adapted for rotating said key member to said first and said second operating positions, and
- (iii) at least one stop cam member formed integral with a skirt portion of said operating button and extending downwardly therefrom into a groove upon the body portion of said bridge member, said at least one stop cam member adapted to define said first and said second operating positions of said key member.
