[Problem] The purpose of the invention is to provide a container valve with which it is possible to reliably switch between stopping and releasing a fluid, and with which it is possible to prevent production of the sound of the conduction of the fluid being released. [Solution] A container valve 1 in which a residual pressure holding valve mechanism part 100 is mounted in a residual pressure holding valve mechanism insertion space 404 formed in a flow path 60, wherein the residual pressure holding valve mechanism part 100 is provided with: a forward-projecting part 127 disposed so as to be able to advance or withdraw to a closed valve position and an open valve position in the residual pressure holding valve mechanism insertion space 404, the forward-projecting part 127 being disposed at the tip of a valve body 120 that withdraws to the open position due to the pressure of a gas G that is conducted through the flow path 60; a coil spring 160 for urging the valve body 120 in an advancing direction from the open position to the closed position; and a seal seat body 110 and pressing part 135 for holding an O-ring 150 while exposing a contact-permitting part 151 for permitting contact with the forward-projecting part 127, the seal seat body 110 and the pressing part 135 being secured to an outlet 40. |
