The hand manipulatable sprayer (10) is connectable to a container (26) and includes a body (12) having a pump assembly (120) and a check valve assembly (90). The check valve assembly (90) includes at least one conically-shaped skirt valve member (100,112). Also the body (12) can have a cavity (68) adapted to receive similarly shaped inserts (67) for different valve assemblies (90), a cylindrical cavity (68) for receiving various size pistons (34) together with a mating cylindrical insert (43) and a nose formation (15,142,143) adapted to receive nozzle assemblies (14) similarly shaped but of different types and a passageway (96,97) extending from the cavity (68) to and opening on the nose formation (15).

Sprayer

The check valve is used to control the flow of fluid through a cylindrical passageway having a cylindrical wall surface and comprises an elongate umbrella valve member having a frusto-conical shaped skirt extending radially outwardly and axially of the valve member. The skirt is positioned to extend in the downstream direction of the flow of fluid through the passageway and in frictional, sealing engagement with the cylindrical wall surface of the passageway but yet being flexible enough to deflect inwardly under fluid pressure to allow fluid to flow downstream past the skirt.

Check valve

The trigger sprayer comprises a body having an upper horizontally extending portion and a lower generally vertically extending portion. The body has a passageway therein extending from one end of the upper portion to the bottom of the lower portion. A cylindrical hollow and a cylindrical cavity extend into the lower body portion from the bottom thereof. An insert member is adapted to be received in the hollow and cavity, and has a passageway therethrough communicating with the body passageway, a cap coupled to the lower end of the insert member to a container of fluid. A check valve assembly is associated with the insert member to a container of fluid. A check valve assembly is associated with the insert member passageway and includes a lower check valve. At least one of the valves including an elongate valve member and a frusto-conical shaped skirt extending forwardly from the valve member. A pumping assembly is mounted to the body and communicates with the insert member passageway between the upper and lower check valves.

Trigger pump sprayer

A child-resistant nozzle in combination with a hand operated sprayer is disclosed. The nozzle and the discharge end of the sprayer are movable into positions of relative adjustment including a liquid flow OFF position and one or more liquid flowing positions and have cooperating surfaces in which passages are formed, which passages when brought into register by relative adjustment of the nozzle and discharge end determine the mode of liquid discharge, i.e., SPRAY or STREAM. Locking members are also provided on the nozzle or discharge end which cooperate when engaged by other parts of the device to prevent sprayer operation by preventing relative adjustment of the nozzle and discharge end from said liquid flow OFF position without the application, simultaneously, of discrete, predetermined actions of the members and parts.

Child-resistant liquid dispenser sprayer or like apparatus

A caster which includes a neck at its top portion and a support at its lower portion to which a wheel is rotatably connected. About the neck are a ball bearing retaining plate and a top plate above and releasably secured to the ball bearing retaining plate. Within the plates and about the neck is a completely enclosed raceway which encapsulates thrust ball bearings. The top plate can readily be removed from the ball bearing plate to permit inspection, cleaning, modification, repair and replacement of components of the casters.
