A refill container plug that covers the refill outlet of the refill container for refilling the contents of the refill container,
A plug body that is bonded and fixed to the peripheral edge portion of the opening of the refill outlet, and a plug that is detachably mounted on the plug body by closing the outflow opening formed in the top plate of the plug body from the inside in the outflow direction. A lid,
The stopper body surrounds the outflow opening and protrudes outward from the top plate in the outflow direction, and the mouth portion of the refill container that surrounds the outflow tube and protrudes out of the top plate from the top surface in the outflow direction. A cylindrical outer wall having an inner diameter that is substantially the same as the outer diameter of and an installation cylinder that surrounds the outflow opening and protrudes inward in the outflow direction from the top plate,
The stopper body is adjacent to the outer side in the radial direction of the outflow tube, or is inserted into the top plate, or continuously from the peripheral edge of the outflow opening to the outer side in the radial direction of the outflow tube. The face plate is provided with a notch formed in the notch, and an opening is formed in the top plate in a region between the outer peripheral surface of the outflow tube and the outer peripheral surface of the mounting tube and the inner peripheral surface of the cylindrical outer wall. It has an open air communication port,
The plug lid includes a mounting wall surface portion whose outer peripheral surface is in close contact with the inner peripheral surface of the mounting tube, a closing plate portion having a planar shape similar to the hollow cross-sectional shape of the mounting tube, and a peripheral portion of the closing plate portion It has a push-in projection that stands upright,
The pushing convex portion protrudes outward in the outflow direction along the outflow tube from the top plate through the insertion port, and at least a part of the front end surface of the pushing convex portion from the outer peripheral surface of the outflow tube. A plug body for a refill container in which the plug lid is mounted on the plug body in a state where the plug lid is arranged on the radially outer side.   When refilling the contents, the inner peripheral surface of the cylindrical outer wall is along the outer peripheral surface of the mouth portion of the refill container, and the plug attached to the refill container is replaced with the refill By pushing in toward the container, the pushing convex portion whose end face is in contact with the end face of the refill container is pushed into the refill container, and the stopper lid is attached to the mounting cylinder. By dropping from the above, the outflow opening is opened, the contents are allowed to flow from the refill container into the refill container, and the push-in convex portion is pushed out through the insertion opening. 2. The filling according to claim 1, wherein air replacement is performed between the refill container and the refill container, and air replacement is performed between the refill container and the outside air through the outside air communication port. Replacement container plug.   In the outflow cylinder, at least a portion near the portion from which the pushing protrusion protrudes and both side portions of the portion are outer peripheral portions along the inner peripheral shape of the mouth portion of the refill container, The plug for a refill container according to claim 1 or 2, wherein a gap larger than a wall thickness of a neck portion of the refill container is maintained between an outer peripheral shape portion and the cylindrical outer wall.   A guide inner wall having an outer peripheral shape portion along the inner peripheral shape of the mouth portion of the refill container is arranged in the outflow direction outward from the top plate so as to circumscribe the protruding protrusion of the outflow cylinder. The plug body for a refill container according to claim 1 or 2, wherein the plug body is provided on the plug body so as to protrude from the top.   5. The plug lid is attached to the plug main body by causing the pushing convex portion to protrude at a height lower than the tip of any one of the outflow cylinder, the cylindrical outer wall, and the guide inner wall. The plug for a refill container according to any one of the above.   The plug for a refill container according to any one of claims 1 to 5, wherein the plug lid is made of a material having a specific gravity lower than that of the contents.   The mounting wall surface portion of the plug lid has a hollow cylindrical shape, and the closing plate portion of the plug lid closes the inner portion in the outflow direction of the mounting wall surface portion. And the said obstruction board part is the stopper for refill containers of any one of Claims 1-6 which has formed the concave shape opened toward the outflow direction outer side.   The plug body for a refill container according to any one of claims 1 to 7, wherein a position correcting rib is provided at a position facing the indentation convex portion so as to protrude inward from an inner side surface of the cylindrical outer wall. It is the refilling method of the contents from the refilling container to the refilling container using the plug for refilling containers of any one of Claims 1-8 , Comprising: The outer peripheral surface or inner peripheral surface of the said outflow cylinder Is pushed along the mouth of the refill container, and the plug attached to the refill container is pushed toward the refill container, so that the mouth of the refill container is inserted into the front end surface. The pushing convex part with which the end surface part of the neck abuts is pushed out into the refill container, and the stopper lid is dropped from the mounting cylinder, so that the outflow opening is opened and the contents are removed. A method for refilling contents to be introduced from a refill container into the refill container.
