Trigger Sprayer

A trigger sprayer element for use with a pump and a fluid container, comprising:

• a molded body having a container closure;
• a fluid inlet for receiving fluid from the container via an inlet valve;
• an engaging element for the pump;
• a fluid discharge barrel having a proximal opening coupled to the pump;
• a vent chamber coupled to the fluid container;
• a vent barrel coupling said vent chamber to the ambient, wherein said vent barrel is substantially parallel said fluid discharge barrel and extends beyond said fluid discharge barrel in a direction away from the container.

A trigger sprayer for use with a container of fluid, comprising:

• a pump;
• a shroud which includes a trigger, an actuation element which engages said pump, a front mating element, and a rear mating element;
• a closure for the container;
• a body coupled to said pump and said shroud, and having a fluid discharge barrel, a vent chamber, a vent barrel coupling said vent chamber to the ambient;
• a nozzle coupled to said body;
• and
• a door assembly with a means for plugging said nozzle and a second plug which plugs said vent barrel.

A trigger sprayer for use with a container of fluid, comprising:

• a pump;
• a trigger which actuates said pump;
• a body coupled to said pump and said trigger, said trigger moving relative to said body;
• a nozzle coupled to said body;
• and
• a door assembly with means for closing said nozzle and means for locking said trigger.

A method of assembling a trigger sprayer, comprising:

• placing a ball valve into a body;
• coupling a diaphragm to the body with said diaphragm over the ball valve;
• coupling a trigger shroud to the body with the a portion of the trigger shroud extending over the diaphragm, said trigger shroud being rotatable relative to said body;
• snapping a nozzle and door assembly into the body;
• and
• and pushing a dip tube into the body.

A trigger sprayer for use with a container of fluid, consisting of:

• a ball,
• a dip tube,
• a single piece nozzle,
• a single piece body having an inlet coupled to said dip tube and supporting said ball and having an outlet coupled to said nozzle,
• a single piece pump diaphragm supported over said ball by said body, and
• a single piece shroud above said pump diaphragm, said shroud having an integral trigger, said shroud being pivotally coupled to said body.
