Claims

[Scope of utility model registration request]

The engagement and fixing part between the screw cap 4 and the upper end of the cylinder 5, which can be fixed to the neck of the container body, is held and accommodated between the outer cylindrical parts 6a and 6b inside the fitting cap 6, and is fitted into the upper inner diameter part of the cylinder 5. An engaging protrusion 10 is provided on the piston rod 1 on the joint circumferential surface of the inner cylindrical portion 6a and the piston rod 1 passing through the center hole of the cylindrical portion. The piston rod 1 is provided with an engagement notch 9 in the inner cylindrical portion 6a that guides the piston in the circumferential direction, and is further provided with a discharge valve inside the cylinder. The atomizer is arranged such that the suction valve openings are arranged opposite to each other, and the lower end of the extension part 12a comes into pressure contact with the closed valve ball of the suction valve opening when the piston rod 1 is at its lowering limit.
