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.

貯留液溜まり部3内の流体(通常は空気)は外部と連通
自在になっていて、自由に外部に流出入して非貯留液溜
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.

3を通って外部に放出されるのが阻止されている。The boundary portion 4 partitions the inside of the odorless storage tank 1 into a storage liquid reservoir 2 and a non-reservoir liquid reservoir 3 and separates them completely in a non-communicating state. Performs a function of preventing the release to the outside. This boundary 4
This prevents the odor of the liquid in the stored liquid reservoir 2 from being released to the non-reserved liquid reservoir 3 and prevents the liquid from being discharged to the outside through the non-reserved liquid reservoir 3.

The float plate 4a floating on the liquid surface integrally follows the elevation of the liquid surface of the stored liquid reservoir 2. It goes up and down. For example, an airtight lightweight board is used for the float plate 4a.

The upper end of the flexible sheet 4b is tightly fixed to the upper lid 1a by a screw 4c or the like. Is a screw 4 on the upper surface of the float plate 4a.
It is tightly fixed by c or the like. The flexible sheet 4b has a length substantially the same as the internal height of the odorless storage tank 1 in a vertically extended state in a maximum extended state. For example, an airtight vinyl sheet is used as the flexible sheet 4b.

一定に保つ。When the non-reserved liquid reservoir 3 is reduced, a fluid composed of, for example, air inside the non-reserved liquid reservoir 3 having a volume equal to the volume to be reduced is transferred to the upper lid 1 a constituting the upper surface of the non-reserved liquid reservoir 3. It is released into the outside atmosphere through the formed communication port 7 to keep the pressure inside the non-reserved liquid reservoir 3 constant.

させることはない。At this time, since the stored liquid reservoir 2 and the non-reserved liquid reservoir 3 are completely disconnected from each other by the float plate 4a and the flexible sheet 4b constituting the boundary portion 4, the inside of the stored liquid reservoir 2 is removed. 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.
