摘要： A manual liquid dispenser which has a mounting member (1) engaged fixedly with a guide cylinder (11) from the inner surface of the upper end thereof, depending from a neck portion (4) into a container (3) and engaging cylinder (8) stood upwardly therefrom, a spraying head (24) capable of being depressed and formed with a valve seat (19) of a discharge valve (18) and a valve port (20) at the center thereof on the back surface thereof, a rod member (24) slidably contacted with the inner surface of the guide cylinder (11), and a returning coiled spring (27) for always upwardly lifting the spraying head (14) through the rod member (24) and seating the valve body (25) on a valve seat (19) to close the discharge valve (18), and a communication tubular member (28). Thus, when the spraying head (14) is depressed in case of spraying the liquid in the container, a third pressure chamber C is formed between the outer surface of the lower large-diameter part of the rod member (24) and the inner surface of the lower increased-diameter part of the small-diameter cylinder (6).

摘要： 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.

摘要： There is provided a safety cap which requires manual dexterity for a cover opening operation and is difficult for an infant or the like to open a cover, in which a safety function can be released, as necessary. In the safety cap configured such that a part of an outer circumferential wall of a cap main body is formed on an inward elastically deformable operating plate, a pair of engaging means and engageable with each other are provided on a peripheral wall of a cover connected to the upper portion of the cap main body via a hinge and at the upper portion of the operating plate, respectively, and the engagement is released by elastically deforming the operating plate inward so as to open the cover, the operating plate can be fixed to the cap main body or a neck portion of the container except for the operating plate by the fixing member in the inward deformed state.
