Claims

[Scope of utility model registration request]

An operating device consisting of a cylinder and a piston, which is connected to a piston mid fixed to the piston and a movable side of the opening/closing section, and holds the piston mid in either the open or closed state of the opening/closing section. The piston mid is inserted into the container in an airtight and slidable manner, one end of the piston mid is connected to the piston of the operating device disposed in the outer axial direction of the container, and one end is connected to the container wall. A swing lever is disposed via a shaft inserted and fixed, the middle of the swing lever and the piston mid are movably connected via a connecting lever, and a rotation pin is attached to the other end of the swing lever, - A cam lever having a chevron-shaped cam portion that engages with the rotary pin is provided, one end of the cam lever is rotatably fixed, and the chevron-shaped cam portion presses the rotary pin via a compression spring, causing the piston mid to open or open. In accordance with the swinging movement of the swinging lever in response to the movement accompanying the closing operation, the rotating pin is pressed to either the open side of the chevron-shaped cam portion or the closing side inclination, and moves to the piston mid via the swinging lever. An opening/closing holding device, characterized in that the opening/closing holding device holds the container and allows the rotational movement of the shaft fixed to the swinging lever to be guided to the outside of the container.
