    Abstract: A pump mechanism for a spray dispenser, comprising a piston assembly movable with respect to a housing between charged and initial positions. The piston assembly comprises liquid and gas seals, being movable boundaries of respective chambers whose volume is determined by the position of the seal relative to the housing. When the piston assembly moves toward the charged position, the volume of the liquid chamber increases to draw liquid into the liquid chamber and the changing volume of the gas chamber changes the pressure of gas in that chamber from its pressure when the piston assembly was in the initial position. This biases the piston assembly to return from the charged position toward the initial position, that return movement of the piston assembly pressurising the liquid in the liquid chamber for dispensing.

    Abstract: A hand pump for pumping out fluid from a reservoir, comprising a pump body, a faucet, a driving mechanism and a sealing arrangement. The pump body has at a side a connector defining a receptacle radially extending into a cavity of the pump body. The driving mechanism includes an axle inserted in the receptacle of the connector, a sealing sleeve mounted around the axle, a coupling cap axially secured to the sealing sleeve, and a L-shaped handle. The handle having at one end inserted through the coupling cap and the axle, and at the other hand extending outside the coupling cap. Operation of the handle in cyclically up and down motion drives the axle to rotate, which causes a piston in the cavity to move upward and downward so as to suck the fluid into the faucet. The sealing arrangement has at least three O-rings disposed among the parts of the driving mechanism to provide an effective seal between the driving mechanism and the pump body.

    Abstract: A trigger-type liquid dispenser includes a dispenser main body, pump, and nozzle. The body includes a fitted portion, which communicates with a delivery port. The nozzle includes a partition wall, which covers an opening end of the fitted portion and has a dispensing hole, and an outer circumferential wall. The nozzle is rotatable with respect to the fitted portion between an opened position, wherein the hole communicates with the port, and a closed position, wherein the hole is blocked. The outer circumferential wall includes a locking projection, in undercut engagement with a projecting portion, on an outer surface of the fitted portion, to hold the nozzle in engagement with the fitted portion. The locking projection, in an inner edge portion thereof, has a concave portion, wherein the degree of undercut engagement with the projecting portion is reduced when the nozzle is located between the opened and the closed position.

    Abstract: A scraping cleaner can include a bottle, a sprayer mechanism, and at least one scraping edge. The bottle can have a body portion extending along a vertical axis from a base that is substantially flat to a top that defines a connecting portion. The body portion can be configured to receive and retain a liquid cleaning solution in a cavity. The sprayer mechanism can include a pump assembly. The pump assembly can have a pump and a lever. The lever can be pivotally engaged with the pump such that pivoting movement of the lever induces the pump to draw the liquid cleaning solution from the cavity. The scraping edge is integral with the body portion and is positioned at the base. The at least one scraping edge extends along a path in a plane that is transverse to the vertical axis.
