を設けたことを特徴とする定量栓。 A cylindrical inner stopper 3 with a bottom is fitted into the mouth 2 of the container 1, and the bottom of the inner stopper 3 protrudes upward, and the bottom is open to the inside of the container 1, and the tip is open. A conical cylinder 5 is provided protrudingly, and a swinging cylinder 1 is provided at the tip opening 4 of the conical cylinder 5 and is made of a material having a diameter smaller than that of the opening 4 and having a higher specific gravity than the liquid in the container.
An annular valve 12 having a larger diameter than the opening 4 is provided around the inner end of the container of the swinging cylinder 11, and a flange 13 having a larger diameter than the opening 4 is also provided around the outer end of the container. Furthermore, an intake pipe 14 directed toward the bottom of the container 1 is connected to the inner end of the container 11 of the swinging tube 11, and a cup 21 is connected to the mouth 2 of the container 1.
is removably attached, and when the length of the swinging cylinder 11 is adjusted so that the flange 13 comes into contact with the inner bottom surface of the cup 21, the annular valve 12 closes the tip opening 4 of the conical cylinder 5.
The length is such that a liquid outflow path 15 is formed between the middle part of the swinging cylinder 11 and the opening 4 without blocking the opening 4, and further,
When the flange 13 comes into contact with the inner bottom surface of the cup 21, a rocking force is generated between the flange 13 and the inner bottom surface of the cup 21, either on the flange 13 of the swinging cylinder 11 or on the inner bottom surface of the cup 21 corresponding to the flange 13.
