ABSTRACT:
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).
