Means for Solving the Problems From the upper end of the trunk 2 to the mouth and neck 4
And an inner cylindrical portion 9 is suspended from the upper end of the mounting cylindrical portion 7 fitted to the outer surface of the mouth and neck portion 4 into the upper portion of the container body 1 via an inward flanged top wall 8. At the same time, a discharge valve 15 is attached to a small-diameter cylinder 11 vertically extending from the lower end of the inner cylinder portion via an inward flange-like wall 10, and an air intake valve hole 16 is formed in a part of the cylinder wall above the discharge valve. A perforated mounting member 6 and a suction pipe 17 vertically extending from the lower end of the small-diameter cylinder 11 to the bottom of the container.
And the air suction valve hole 16 fitted on the outer surface of the small-diameter cylinder 11
And an elastic valve cylinder 18 forming an air suction valve 19, and a liquid measuring device 20 mounted on the mounting member 6. The liquid measuring device is mounted on the inner surface of the small-diameter cylinder 11 above the air suction valve hole 16. The inner pipe part 25 and the fitting cylinder parts 24a, 24b are fitted from the inner peripheral part and the outer peripheral part of the outward flange 23 attached to the upper end of the discharge pipe part. A tubular member 21 erected, a bellows tube 28 having a lower end portion of the tube wall fitted to the fitting tube portions 24a, 24b, and a short tube portion hanging from the lower surface of the closing plate 34 on the outer surface of the upper end of the bellows tube. 35 is rotatably fitted to hermetically close the upper end opening of the bellows cylinder 28, and
The lower end outer surface of the adjusting tube 36 vertically suspended from the center of the closing plate portion surrounded by the upper end is formed by the liquid amount adjusting member 33 pushed down and rotatably fitted into the upper end of the inner tube portion 25, Inner tube part 25
In addition, a vertical groove 26, 26 having a wide upper part and a narrow lower part is formed, and an appropriate number of upward step portions 27a,
At the same time, engaging protrusions 37, 37 which engage with the upper surfaces of the upward step portions 27a, 27b by pressing down the closing plate 34 are provided vertically on the upper outer surface of the adjusting tube 36.

[0006]

1 and 4 show a state in which the amount of the liquid to be measured is minimized. The closing plate 34 is pushed down from the state shown in the drawing until the engagement ridges 37, 37 contact the upper end of the inner tube portion 25. When the bellows cylinder 28 is elastically squeezed, the air in the bellows cylinder is pressurized and the air intake valve hole 16 is compressed.
When the bellows cylinder 28 expands due to the elastic restoring force of the bellows cylinder 28 itself and the internal pressure is reduced, the discharge valve 15 is opened. A fixed amount of the liquid in the container is sucked into the bellows cylinder 28 via the suction pipe 17, and the measurement is completed. The liquid inhaled in this way is
The liquid meter 20 is removed from the mounting member 6 and the closing plate 34 is removed.
The bellows cylinder 28 is elastically squeezed through the outlet tube 22 to be poured out, and after use, the outlet tube portion 22 is fitted into the small-diameter tube 11.

The amount of the liquid to be measured can be changed by rotating the liquid amount adjusting member 33 with respect to the bellows cylinder 28. For example, from the state shown in FIGS. 1 and 4, the closing plate 34 is appropriately rotated so that the upper upward step 27 provided on the side surface of the vertically dividing grooves 26, 26.
a When the engaging ridges 37, 37 are positioned upward, the amount of the liquid to be measured increases because the amount of pressing down of the closing plate 34 and thus the amount of pressing of the bellows cylinder 28 increase. When the ridges 37, 37 are positioned above the lower upward step 27b, the amount of the liquid to be measured is maximized.
