Claims (1)

[Scope of utility model registration request] A container body 1, a base cylinder member 2 which is fitted and fixed to the container body mouth neck 5, and has a suction pipe 8 which is connected and suspended from a bottom small diameter portion 7 having a suction valve 6 therein and which hangs downwardly inside the container body 1. , the middle part of the small-diameter cylinder 9 whose lower end part is removably inserted into the bottom small-diameter part 7 and extends upward is partitioned, and the lower half part is a liquid suction/drainage pipe 11 with a window 10 opened in the upper part; and a separable central cylindrical member 3 having a piston 12 fixed to the outer surface of the intermediate portion in the form of a brim.
The liquid suction/discharge pipe 11 has a cup-shaped center hole opened in the bottom wall 13 around the liquid suction/discharge pipe 11.
The inner surface of the peripheral wall 14 is in sliding contact with the peripheral edge of the piston 12 and forms a vertically slidable measuring chamber 15 that communicates with the window 10, and a flange-shaped operation plate 16 provided at the upper end of the peripheral wall 14 is connected to the mouth and neck. 5 a movable measuring chamber member 4 which rides on the top surface of the central cylinder member 3, is pulled up when dispensing and is pushed down during suction and metering, and forms a syringe-shaped measuring device with the central cylinder member 3; Liquid metering dispenser.
