防ぐように作用する。The present invention having the above-described structure operates as follows. That is, when the liquid flows into the storage liquid reservoir through the liquid supply passage to be stored in the odorless storage tank, the storage liquid reservoir expands, and the storage liquid reservoir and the non-storage liquid reservoir are brought into a non-communication state. The partitioning portion is displaced and moved toward the non-reserved liquid reservoir, the non-reserved liquid reservoir is contracted, and the fluid inside the non-reserved liquid reservoir is discharged to the outside through the communication port. At this time, since the stored liquid reservoir and the non-reserved liquid reservoir are completely separated and separated from each other by the boundary, the odor of the liquid in the stored liquid reservoir is released to the non-reserved liquid reservoir. No odor is contained in the fluid discharged from the non-reservoir reservoir when the non-reservoir reservoir is reduced, and the odor is removed from the odorless reservoir when the non-reservoir reservoir is stored in the odorless reservoir. It acts to prevent the contained fluid from being discharged.

まり部３の内部圧力を一定に保つようになっている。When the non-reserved liquid reservoir 3 expands and contracts, the fluid (usually air) in the non-reserved liquid reservoir 3 is freely communicated with the outside, so that it can freely flow in and out of the non-reserved liquid reservoir. The internal pressure of the stored liquid reservoir 3 is kept constant.

The odor of the liquid is not released to the non-reserved liquid reservoir 3, and therefore, the fluid composed of air released from the communication port 7 contains no odor,
When the waste liquid or the like is stored in the odorless storage tank 1, no odor is generated.

A boundary part that partitions the two into a non-communicating state is made displaceable by following the expansion and contraction of the stored liquid storage part, and a liquid supply passage and a liquid discharge passage are connected to the stored liquid storage part, respectively. By allowing the liquid reservoir to communicate freely with the outside of the storage tank, it is possible to prevent the odor of the stored liquid from being released to the outside through the non-reserved liquid reservoir, and thereby, when storing in the storage tank. This has an extremely practical and useful effect that it is possible to prevent the generation of offensive odor due to the discharge of odor from the storage tank.
