Thus, even when the bag-shaped main body 12 is formed of a soft packaging material that can be easily deformed by pressing with a finger or a hand, the gripping shoulder 13 by the grip plate 14 of the pedestal part 11 is gripped. As a result, it is possible to perform an operation of forming the refill outlet in a stable state, and the refill outlet is smoothly communicated with the inside of the neck portion 24, so that the liquid content can be easily supplied to the bottle container 20. It becomes possible to refill.

  Furthermore, according to the soft packaging container 10 for refilling of this embodiment, the base part 11 which has considerable shape retention rigidity is attached to the bag-shaped main-body part 12 formed with the flexible packaging material rich in flexibility. Thus, it is possible to effectively prevent clogging by the content liquid at the refill outlet at the time of refilling, and pedestal parts that are joined together along the bag-like main body 12 by adhesive bonding or fusion bonding 11 has a thin and flat shape with a thickness of about 0.5 to 3 mm, for example, so that the content liquid is blocked at the connection portion between the bag-like main body 12 and the base part 11. It is possible to effectively prevent and achieve a smooth refilling of the content liquid.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, it is not always necessary to provide a guide wall around the planned opening portion of the refill outlet on the pedestal part, and a pouring cap having a pouring spout is attached as a mounting member to the mouth of the refill container. It is not always necessary. You may make it form a refill outlet by pushing a base part directly into the mouth part of a refilling container and breaking a thin wire | line, without going through a mounting member. The pedestal part can be joined along the back surface of the bag-shaped main body. It can also be used by being joined to other parts other than the upper surface part of the bag-like main body part. For example, it can be used by being joined to the side surface of the bag-like main body. The content liquid for refilling accommodated may be other various refilling liquids such as cosmetics and seasonings other than the liquid detergent.

  Further, since the pedestal part does not require assembly, it is preferable that the pedestal part is formed as a single-piece member integrally formed. For example, as shown in FIG. 4, the pedestal part 30 includes the plate-side part 31 and the outlet side. It is preferable to form two parts with the part 32 in that each part can be easily molded. That is, the pedestal part 30 includes a plate-side part 31 including a holding plate portion 33 and an annular mounting wall 35 provided upright from an opening peripheral portion of an outflow hole 34 formed in the holding plate portion 33. The outlet side part 32 is provided with a top plate part 38 having a refill outlet scheduled opening portion 37 partitioned by a thin wire 36, and extending downward from the peripheral part of the top plate part 38. The annular skirt wall 39 is formed, and the annular skirt wall 39 is attached to the annular attachment wall 35 so that the plate side part 31 and the outlet side part 32 are joined and integrated, and the pedestal part 30 is It can also be configured.

  Furthermore, the grip plate portion of the pedestal part is not necessarily provided with a planar shape in which a pair of overhang portions are projected on both sides of the substantially circular collar winding portion, and can be formed in various other shapes. For example, as shown in FIGS. 5 (a) and 5 (b), an elliptical planar shape or a planar shape in which the protruding portion is a circular ring shape may be provided. For example, as shown in FIGS. 6A and 6B, it is possible to provide a planar shape in which the overhanging portions are projected in two different directions or four directions.

  Furthermore, the bag-shaped main body portion does not necessarily need to be a pouch-shaped main body portion, and may be bag-shaped main body portions of various other shapes formed by flexible soft packaging materials. For example, as shown in FIG. 7, it may be a side gusset bag-shaped main body.
