Claims

[Scope of utility model registration request]

An orifice operating device that is attached to an orifice formed in a container, and in which an opening/closing tool for opening and closing an orifice plug is held by a holding cylinder, and is detachably attached to the opening of the orifice. It has a holding cylinder, an opening/closing tool, and a connector that communicates the orifice with the outside, and the holding cylinder, the opening/closing tool, and the connector are configured to be separable from each other. Connecting means for removably connecting the holding cylinder and the opening/closing tool or the holding cylinder and the connector to each other is provided, and the opening/closing tool opens and closes the orifice plug while connected to the holding cylinder. The connector is composed of a connector main body and a protruding pipe, the connector main body has an outer circumferential surface that contacts the inner circumferential surface of the holding cylinder through a sealing material, and the protruding pipe is inserted into the bottom of the interior of the container through an orifice. An orifice operating device configured to open at a certain position.
