Abstract
A trigger sprayer having a venting system including a piston bore and a vent bore at least partially contained therein, the vent bore including at least one vent port; a piston and vent piston are moveably seated in the piston bore and vent bore, respectfully, the vent piston including at least one annular seal and a vent path port, the vent path port and vent port in gaseous communication when the vent piston is actuated and moved over the vent port.
Claims8
A dispensing system, comprising:
- a bottle;
- a trigger sprayer, comprising:
- a valve body, comprising:
- a piston bore, comprising:
- an opening in a first end;
- a piston wall at a second end;
- and
- a spring seat in the piston wall;
- a vent bore within the piston bore, comprising:
- an interior vent bore surface;
- a vent bore opening at a first end;
- a vent bore wall at a second end;
- and
- at least one vent port adjacent the vent bore wall;
- a neck portion;
- an inner cylinder;
- an inlet port providing an inlet fluid flow path between the inner cylinder and the piston bore;
- a discharge passage;
- a valve body fluid outlet at an end of the discharge passage;
- an outlet port providing an outlet fluid path between the piston bore and the discharge passage;
- a piston seated in the piston bore;
- a vent piston connected to the piston and seated in the vent piston bore, the vent piston comprising:
- a vent piston open end;
- a first annular vent seal engaging the interior vent bore surface;
- a second annular vent seal engaging the interior vent bore surface;
- a vent path port opening between the first annular vent seal and the second annular vent seal;
- and
- a vent path extending between the vent path port and the vent piston open end;
- a spring seated in the spring seat and in contact with the piston;
- a spin mechanic insert seated against the valve body fluid outlet;
- a rotatable nozzle seated on the valve body adjacent the spin mechanic insert;
- a shroud attached to the valve body;
- a tube retainer seated in the inner cylinder, the tube retainer comprising a valve seat;
- a valve seated in the valve seat;
- a closure engaging a lower end of the neck portion;
- and
- a gasket seated on an interior of the closure and in contact with the valve body;
- and
- wherein the trigger sprayer is connected to the bottle by the closure.
