  In addition, the refilling container 100 holds the plug member 50 attached to the pedestal 20 which is located at the lower part of the bag-shaped main body 10 in an inverted state where the bag-shaped main body 10 is gripped, and the refillable container 200. When the plug member 50 is pushed into the spout 221, the plug member 50 is hidden by the bag-shaped main body portion and becomes invisible. At this time, the plug member 50 is attached to the annular wall 40 that protrudes outward from the pedestal plate-shaped portion 30 of the pedestal 20 provided at the lower portion of the bag-shaped main body 10. The ring-shaped wall 40 is screwed onto the ring-shaped wall 40 and rises outward from the plate surface of the pedestal plate-shaped portion 30 in the direction in which the ring-shaped wall 40 protrudes. As a result, the guide portion 51B provided on the plug main body portion 51 of the plug member 50 is formed so as to rise outward from the plate surface of the pedestal plate-shaped portion 30. Therefore, the refillable container 100 is covered by moving the gripped bag-shaped main body 10 so that the guide portion 51B is a clue and the spout 221 of the refillable container 200 is arranged inside the guide portion 51B. Positioning can be performed smoothly with respect to the refill container 200.

  Further, in the refill container 10 of the present embodiment, the pedestal plate-shaped portion 30 surrounds the expected opening portion 22 around the expected opening portion 22 for the refill outlet 21 having the plug member 50. Are provided with overhang portions 32, and each of the overhang portions 32 is provided with a bending guide portion 33. Therefore, the bag-shaped main body 10 is gripped in a state where the refill container 100 is inverted, and the gripping force presses at least a portion of the bag-shaped main body 10 excluding the lower part where the pedestal 20 is provided. Then, when the content liquid is pressurized, the pedestal plate-shaped portion 30 is provided at a plurality of positions around the planned opening 22 for the refilling outlet 21 in the lower portion of the bag-shaped main body 10 where the pedestal 20 is provided. Is formed so as to bend the overhanging portion 32, and the bent shape body 34 is stretched outward by the action of the pressure of the content liquid to be retained. Thereby, the opening scheduled portion 22 for the refilling outlet 21 provided with the plug member 50 in the pedestal 20 provided at the lower portion of the bag-shaped main body portion 10 is gripped to the spout 221 of the refillable container 200. When pushed in, the bag-shaped main body 10 and the pedestal 20 are unlikely to be displaced such as swinging in four directions surrounding the scheduled opening portion 22 for the refilling outlet 21, exert a stable pushing force on the pedestal 20, 21 can be opened stably.

  Further, in the refill container 100 of the present embodiment, the bag-shaped main body portion 10 has a gusset bag shape. Thereby, as shown in FIG. 4 (C), when the content liquid is filled in the bag-shaped main body 10, the height direction interval H formed by the top surface 11 of the bag-shaped main body 10 with respect to the bottom surface 12 is reduced. In addition, a large capacity can be secured in the bag-shaped main body 10 while the bag-shaped main body 10 is easily grasped in the palm of the hand. That is, it is possible to hold a wider area in the height direction of the bag-shaped main body 10 with the palm of the hand while increasing the capacity of the bag-shaped main body 10. Therefore, as shown in FIG. 4C, the height direction range H1 in which the bag-shaped main body 10 is gripped by the palm is changed to the height direction of the bent-shaped body 34 formed by the projection 32 of the base plate-shaped part 30. By approaching the range H2, the pushing force for gripping the bag-shaped main body 10 and pushing the plug member 50 provided on the pedestal 20 into the refillable container 200 can be more stably exerted on the pedestal 20. However, in the present invention, the height range H1 in which the palm grips the bag-shaped main body 10 extends closer to the lower part of the bag-shaped main body 10 than the range shown in FIG. May be overlapped with the height direction range H2 of the bent-shaped body 34 formed by the overhang portion 32 of FIG.

  In addition, it is preferable that the top surface portion 11 and the bottom surface portion 12 have a shape close to a square so that the gusset bag-shaped bag-shaped main body 10 has a stable shape when formed in a three-dimensional shape. Therefore, when folded in a flat shape, the length from the left end seal portion S1 to the right end seal portion S2 is longer than the length from the front side portion 13 to the rear side portion 14.

  The present invention can be variously modified without being limited to the above embodiment. For example, the outlet forming member provided at the opening scheduled portion of the refill outlet is not limited to the plug member which is dropped and opened by the spout or the like provided at the opening of the refillable container. That is, a thin line is provided on a partition member serving as an outlet forming member provided at an expected opening of the refill outlet of the pedestal, and the thin line is broken by a spout or the like for pouring out a refillable container, whereby the filling is performed. The one that opens the replacement outlet may be used.
