Hand pump sprayer with rotating nozzle and system for dispensing viscous liquids

A hand pump sprayer wherein fluid is brought from a reservoir, pressurized and brought to an outlet of a delivery passageway and dispensed to the atmosphere upon pulling a trigger comprising:

• a. a trigger interconnected to a piston for pressurizing said fluid;
• b. a nozzle having nozzle inlet and nozzle outlet means and a nozzle center;
• c. a delivery passageway in fluid communication with said reservoir and said nozzle;
• d. means for delivering said fluid to said delivery passageway when said trigger is pulled;
• e. said nozzle rotatably mounted to said hand pump sprayer for rotation of from 180.degree. to 360.degree. about an axis X through said nozzle center;
• f. a drive gear interconnected to and operatively driven by said trigger;
• g. a nozzle gear operatively connected to said drive gear for rotational movement;
• h. said nozzle interconnected to said nozzle gear so that said nozzle is rotated by said nozzle gear from 180.degree. to 360.degree. about the axis X through the nozzle center simultaneously with the dispensing of said pressurized fluid through said nozzle to the atmosphere through said nozzle outlet means when said trigger is pulled.

A dispensing system for spraying liquids comprising:

• a liquid to be sprayed;
• a reservoir for holding said liquid;
• a hand pump sprayer wherein the liquid is brought from a reservoir, pressurized and brought to an outlet of a delivery passageway and dispensed to the atmosphere;
• said hand pump sprayer comprising:
• a. a trigger interconnected to a piston for pressurizing said liquid;
• b. a nozzle having a nozzle inlet and a nozzle outlet means and a nozzle center;
• c. a delivery passageway in fluid communication with said reservoir and said nozzle;
• d. means for delivering said liquid to said delivery passageway when said trigger is pulled;
• e. said nozzle rotatably mounted to said hand pump sprayer for rotation from 180.degree. to 360.degree. about an axis X through said nozzle center;
• f. a drive gear interconnected to and operatively driven by said trigger;
• g. a nozzle gear operatively interconnected to said drive gear for rotational movement;
• h. said nozzle interconnected to to said nozzle gear so that said nozzle is rotated by said nozzle gear from 180.degree. to 360.degree. about the axis X through said nozzle center simultaneously with the dispensing of said pressurized liquid through said nozzle to the atmosphere through said nozzle outlet means when said trigger is pulled.
