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 foamed water discharging device includes a water feeding hole, a water discharging hole, a water passage, a ventilation passage, and a foamed water generator. The water passage has a cylindrical inner circumferential surface extending from the water feeding hole to the water discharging hole. The ventilation passage takes in external air on the upstream side of the water passage. The foamed water generator causes water containing the external air to undergo a collision on the downstream side of the water passage so as to convert the water into foamed water. The foamed water generator includes flow dividing ribs along the inner circumferential surface of the water passage, which protrude radially toward the center of the water passage. On a top portion of each flow dividing rib, at least a pair of inclined surfaces are formed to divide, rightward and leftward, water inflowing from a water guiding passage through the water feeding hole.

Abstract: Provided is a trigger-type liquid dispenser (1) including an operating lever (6) held swingably by a main body portion (3) in which a pump is disposed and including a spring member (7) that imparts restoring force to the operating lever (6). The trigger-type liquid dispenser (1) is configured to draw, pressurize, and force-feed a content liquid contained in a container (C) to dispense the content liquid through a nozzle (5), by actuating the pump in response to the operating lever (6) being pulled repeatedly. The spring member (7) is held swingably with respect to the main body portion (3), and, in response to the operating lever (6) being pulled, the spring member (7) undergoes elastic deformation and swings with respect to the main body portion (3).
