Abstract:
[Problem] To provide a connection structure for connecting a conduction port and a pipe end, an open/close valve device, and a removal method for a sealing member, with which it can be easy to replace a sealing member that can be disposed at a suitable position in a state in which the conduction port and the pipe end are connected to each other. [Solution] This connection structure X for a conduction port 12 of a container valve device 1 and a pipe end 102 of a flow path pipe 100 is configured such that: the conduction port 12 and the pipe end 102 are arranged to abut each other; a ring-shaped gasket 20 having an opening 21 into which a substantially columnar insertion tip 203 of a removal jig 200 can be inserted is disposed between the conduction port 12 and the pipe end 102, the gasket; a fitting groove 122 for fitting the gasket 20 is formed in the conduction port 12; and a tapered space 123, for preventing interference with the insertion tip 203 when the removal jig 200 having the insertion tip 203 thereof inserted into the opening 21 is inclined in order to remove the gasket 20, is provided to a body side B in a fitted state in which the gasket 20 is fitted to the fitting groove 122.
