Is opened, the liquid in the first liquid storage section 11 is sucked into the first cylinder 8, and the liquid in the second liquid storage section 12 is sucked into the second cylinder 9. At this time, the movable bottom wall 4 rises as the liquid in each of the storage sections 11 and 12 decreases, and the inside of each of the storage sections 11 and 12 is always filled with the liquid. In addition, the movable bottom wall 4
Rises at the same level, so that each liquid eventually disappears at the same time. Further, the suction valve 14 and the discharge valve 24 also serve to make the movable bottom wall 4 ascend more smoothly.

"Example" Hereinafter, an example of the present invention will be described with reference to the drawings. The drawings show one embodiment of the present invention, in which 1 shows a two-drain container, which is composed of a container body 2, a press-down head 3, and a movable bottom wall 4 as main members. I have.

The container body 2 has a cylindrical, flat top wall 6 extending from the upper end of the outer cylindrical portion 5 having a lower end surface opening, and a cylindrical lower end surface opening extending from the center of the back surface of the top wall 6 to the upper inside of the outer cylindrical portion 5. The inner cylinder portion 7 is vertically suspended in a double cylindrical shape. A large-diameter first cylinder 8 and a small-diameter second cylinder 9 are provided upright from the upper surface of the top wall 6.

The movable bottom wall 4 has an annular concave groove 10 into which the above-mentioned container body cylindrical portion 7 formed by cylindrically recessing the center downward is insertable. The periphery is fitted so as to be liquid-tight and slidable. The upper end of the inner wall of the annular groove 10 is fitted to the lower end of the inner circumferential portion 7 of the container in a liquid-tight manner so as to be slidable. The inside of the outer cylinder part 5 above the movable bottom wall 4 is configured as a first liquid storage part 11, and the inside of the inner cylinder part 7 is configured as a second liquid storage part 12. Further, a pair of through holes 13 are formed before and after the top wall 6 of the container body, and suction valves 14 for closing and opening the respective through holes 13 are provided. It is unilaterally connected to the cylinder 8. Also, a through hole 15 is formed in the center of the top wall 6 so that the second liquid storage portion 12 and the second
The inside of the cylinder 9 is communicated.

A cylindrical exhaust port 16 is provided at the center of the movable bottom wall 4 for filling the contents, and a cylindrical plug 17 is provided at the lower end of the port 16.
