Claims (1)

[Claims for Utility Model Registration] (1) A liquid container that is removably attached to the spout of a fluid container having a spout formed with a spout that allows fluid to enter and exit the fluid container; A valve member having a valve body that is movable in the longitudinal direction of the discharge port between a closed position where the discharge port is closed and an open position where the discharge port is opened, and a valve body biasing means that biases the valve body to the closed position. ; removably connected to the valve member; when connected to the valve member, the valve body is moved from the closed position to the open position against the urging force of the urging means; and when the connection with the valve member is released, the valve body is moved; a valve body drive unit that allows the body to move from the open position to the closed position by the biasing force of the biasing means; and a valve body drive unit that communicates with the interior of the fluid container when the valve body is placed in the open position, and the valve body is in the closed position. A connecting member having a fluid passage hole that blocks communication with the inside of the fluid container when placed; and a diaphragm in which the valve element biasing means of the valve member is integrally formed with the valve element. A discharge port connection device for a fluid container, comprising: (2) the valve body driving section is provided so as to be movable relative to the connection member between a closed position in which the fluid passage hole is closed and an open position in which the fluid passage hole is opened; A biasing means is provided for biasing the valve body drive unit to a closed position; when the connection member is connected to the valve member, the valve body drive unit comes into contact with the valve body, and the biasing unit is biased. The connecting member is moved from the closed position to the open position against the force, and the valve body is also moved from the closed position to the open position against the urging force of the urging means, and the connecting member is connected to the valve member. When the valve body is released, the contact of the valve body driving portion with respect to the valve body is released and the valve body is moved from the open position to the closed position by the biasing force of the biasing means, and the valve body is opened by the biasing force of the biasing unit. position to the closed position; Claim 1 of the utility model registration is characterized in that:
A discharge port connection device for a fluid container according to paragraph 1. (3) The discharge of a fluid container according to claim 2, wherein the valve body driving section and the urging means are arranged inside the fluid passage hole of the connecting member. Outlet connection device.
