<p><P>PROBLEM TO BE SOLVED: To easily secure seal effect and hardly hinder an operator from inserting his/her hand into a vessel even when the pressure of the fluid is high. <P>SOLUTION: The vessel is provided with a fluid leakage preventive vessel body 5 which freely prevents the fluid G from leaking to the outside from the opening 2 of a partition wall partitioning the fluid storage space and the outside. The seal mounting part 5a freely mounted on the opening 2 of the wall part and the opening 5d for working where the hand can be freely taken in and out from outside, are provided on the fluid leakage preventive container body 5. An annular seal part 14 to seal between hands inserted in the fluid leakage preventive container body 5 is provided on the inner peripheral part of the opening 5d for working. In the fluid leakage preventive container, the seal part 14 is elastically deformably formed, and the seal part 14 corresponding to the outer peripheral side of the seal part 14 is formed to be hardly bent comparing to the seal tip part L2 corresponding to the inner peripheral side of the seal part 14. <P>COPYRIGHT: (C)2004,JPO</p> |
