Abstract
The invention relates to a fluid dispensing device incorporating a push-button actuator normally biased in the closed position, a housing for receiving the aerosol canisters and a carrying case for the entire assembly. Activation is achieved by longitudinal axial compression followed by snapping engagement of the housing fitted about the aerosol valves which depresses the aerosol valves.
Claims57
A device for dispensing a fluid comprising:
- (a) a dispensing housing;
- (b) a chamber in said housing, said chamber having at least one inlet and at least one outlet, each inlet and each outlet having an essentially centrally disposed bore therethrough;
- (c) a means for selective activation of said device from a normally biased off position to an open position to enable fluid communication between said at least one inlet and said at least one outlet wherein said push-button actuator further comprises;
- (i) at least one essentially cylindrical projection from a top of said actuator, said cylindrical projection having at least one transverse bore extending therethrough;
- (ii) said at least one transverse bore positioned such that upon at least partial longitudinal axial movement, at least a portion of said at least one transverse bore will be in fluid alignment with at least a portion of said at least one inlet and at least a portion of said at least one outlet;
- (d) a removable dispensing nozzle having a bore therethrough in fluid communication with said at least one outlet of said chamber;
- and
- (e) a biasing means to bias said selective activation means in said biased off position, and further wherein said biasing means is
- (i) a flap in a bottom side of said housing acting in concert with a projection in contact with a tip of said longitudinally axially extending cylindrical projection.

- (ii) each side wall in flexible communication with a top wall;
- (iii) one side wall in flexible communication with a bottom wall;
- and
- (iv) said bottom wall in flexible communication with a closure means.
