For example, the packaging bag body 110 is a flexible packaging bag including two side films and a bottom film sandwiched between the two side films. The packaging bag main body 110 forms a seal portion 111 by sealing one peripheral film, a bottom film folded in two, and the other lateral film in this order, and then sealing the peripheral portions of the two lateral films. To do. Thereby, the accommodating part 112 which is the space for accommodating the contents, and the scheduled opening part 114 in which the opening for allowing the contents to flow out are formed are formed. As shown in FIG. 2, the accommodating portion 112 may include a funnel portion that decreases in width toward the planned opening portion 114 in order to promote the outflow of the contents during refilling.

  Moreover, the packaging bag main body 110 is provided with the scheduled opening line 113 for breaking a part of the packaging bag main body 110 when refilling the contents. As shown in FIG. 2, the planned opening line 113 is formed, for example, between the opposing end portions of the packaging bag main body 110 so as to pass through the end portion of the housing portion 112. An opening is formed in the flexible packaging bag 100 by breaking a part of the flexible packaging bag 110 along the planned opening line 113. For example, a weakening line such as a half cut or a perforation formed on the surface of the side film can be employed as the planned opening line 113. Further, in order to facilitate the breaking of the side film, a pair of notches (notches) formed inward of the packaging bag body 110 may be provided at the end of the planned opening line 113.

[Opening parts]
The opening part 120 is a member that is attached from the inside of the flexible packaging bag 100 in the vicinity of the planned opening line 113 and holds the opening formed in the flexible packaging bag 100 in an opened state.

FIG. 3B shows a state in which the opening part 120 is bent and the opening of the packaging bag body 110 is held in the open state.

  As an example, the opening part 120 is formed by connecting two strip-shaped members 121 having the same shape at the ends in the longitudinal direction. Each belt-like member 121 includes a bent portion formed of a linear depression formed in the width direction on three surfaces of a center in the longitudinal direction and a position away from the center by a predetermined distance from the center in the longitudinal direction. .

  Thus, the formed opening part 120 can bend the strip | belt-shaped member 121 by applying the force to the direction (direction shown by the black arrow to Fig.3 (a)) which approaches an edge part. Thereby, the opposing surfaces of the two band-shaped members 121 are separated from each other at the center of the band-shaped member 121, and the bent state of the band-shaped member 121 is maintained by the urging force ((b) of FIG. 3).

  As shown in FIGS. 1 and 2, the opening part 120 can be attached from the inside of the flexible packaging bag 100 near the planned opening line 113 by a method such as adhesion. Thus, after the flexible packaging bag 100 is partially broken and an opening is formed in the housing portion 112, the belt-shaped member 121 of the opening part 120 can be bent and held in an open state.

  The shape of the opening part 120 is not limited as long as the opening of the flexible packaging bag 100 can be held open. For example, the opening part 120 may be formed by folding a single belt-shaped member in half. Moreover, in the flexible packaging bag 100, although the opening part 120 was attached to the outer surface of a side film, you may attach to the inner surface of a side film, ie, the inside of the accommodating part 112.
