Title:
CONTAINMENT VESSEL AND WASTE LIQUID SUCTION DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/195360
Kind Code:
A1
Abstract:
A containment vessel (3) has a restricted area (31) preset in a storage vessel (2) as an area that expands in response to formation of negative pressure in the storage vessel (2) and that is used to restrict rupture, and comprises a restricting containment section (25) that has a higher rigidity than the restricted area (31) and contains the restricted area (31). The restricted area (31) is flexible enough to expand from a contracted state (ST1) before the formation of negative pressure to a most expanded state (ST2) in which the restricted area (31) is most expanded due to the formation of negative pressure. The restricting containment section (25) includes a restricting surface (29) having a shape along the restricted area (31) in an expansion process state (ST3) between the contracted state (ST1) and the most expanded state (ST2) so that the restricting containment section (25) can be in close contact with the entirety of the restricted area (31) in the expansion process state (ST3).
