Claims

[Scope of utility model registration request]

an attachment member having a peripheral wall that can be attached to the outer periphery of the mouth and neck of a container; and an engagement tube that stands upright from the peripheral wall; a large-diameter cylinder whose lower half of the peripheral wall has a diameter substantially larger than that of the upper half; a suction valve housed in the bottom opening of the cylinder; and a suction valve that is connected to the suction valve and hangs down from the bottom of the container body. a suction pipe that is fitted into and suspended inside the mounting member;
a small diameter cylinder whose upper part is connected to an injection member main body having an injection mechanism and can be slid up and down by the operation of the injection member main body; the upper part is installed inside the small diameter cylinder with a gap, a piston member whose lower part is enlarged in diameter into a skirt shape; a flexible valve formed at the lower end of the piston member and provided at least diagonally downward and in sliding contact with the inner peripheral surface of the lower part of the large diameter cylinder; the piston member and a spring member disposed between the bottom of the large-diameter cylinder and constantly biasing the piston member upward; a spring member disposed at the bottom of the small-diameter cylinder that connects the cylinder and the mounting member; an outer cylinder whose lower end is in sliding contact with the mounting member side so as to form a first pressurized chamber between; an outer cylinder which is fitted around the outer periphery of the small diameter portion of the piston member, and whose upper end is in contact with the outer cylinder; , the lower end is formed in the enlarged diameter portion of the piston member and is arranged to close a communication hole bored in the radial direction so as to communicate the second pressurizing chamber below the piston member with the first pressurizing chamber. a communicating cylindrical member formed with a hole that communicates the first pressurizing chamber with the gap in the small diameter cylinder; 2. It is a flexible member that expands outward when the pressure chamber reaches a predetermined pressure, and when the piston member is pushed down, the outer peripheral surface of the piston member and the large diameter cylinder A small manual dispenser characterized in that a third pressurizing chamber is formed between the lower peripheral wall of the dispenser and the lower circumferential wall of the dispenser.
