Abstract: A sprayer includes a container for receiving a liquid therein, a sprayer head having a piston for sucking and ejecting the liquid from a nozzle, and a neck portion coupling said head to said container, said neck portion having a vent for permitting the interior of the container to communicate with the open air. Said vent is normally closed by a flexible closing member and, when the piston is operated, is opened by an operating rod to release a negative pressure within the container.

Abstract: A sprayer is adapted to suction a liquid under back pressure and squirt the liquid in the atomized form from the nozzle by applying a pressure to the liquid. The sprayer comprises a sprayer body having a suction pipe and a cylinder communicating with the suction pipe, and a cylindrical projection extending from the closed end toward the open end of the cylinder and communicating with the suction pipe. A piston is slidably mounted to the sprayer body in a manner to surround the cylindrical projection. The piston defines such a liquid chamber that when the piston is moved into closest proximity to the closed end of the cylinder the volume of the liquid chamber is made minimal. As a result, when the piston is so moved, a liquid within the chamber is squirted efficiently at high pressure.

Abstract: This sprayer essentially consists of a body having a cylinder and stock portion, a piston and a handle. The piston has a through passage integrally formed therein, a check valve consisting of a one-piece resilient element and spraying cartridge; resilient element with a recess, in which a spring seats, forms a piston ring preventing leakage, the spring providing a returning force for the piston after handle operation.
