The adhesive margin piece is continuously provided, and the adhesive margin piece is adhered to the back surface of the other front plate corresponding to the one front plate, so that the bottom surface is an open portion formed in a square shape, and the upper portion of both side surfaces. Each of which is a pentahedral paper sleeve that is opened as a side opening portion, and has an insertion hole formed in the center in the vicinity of the folding line at the top of the two front plates folded into the chevron. A paper sleeve for a soft packaging bag with a plug member, which is characterized.

  As described above, according to the first aspect of the present invention, the trapezoidal shape is formed from the two lower end edges of one of the front plates of the two front plates that are bent in a mountain shape via the folding lines, respectively, via the folding lines. The side plate and the adhesive margin piece are connected to each other, and the adhesive margin piece is attached to the back surface of the other front plate corresponding to the one front plate to form an open portion having a bottom surface formed in a square shape. The upper part of the surface is a pentahedral paper sleeve that is opened as a side opening part, and an insertion hole is drilled in the center of the upper part of the two front plates bent in the chevron in the vicinity of the folding line. Therefore, the soft packaging bag with the cap member can be inserted from the opened bottom surface, and the cap member can be protruded from the insertion hole to fix the soft packaging bag to the paper sleeve.

  By fixing the flexible packaging bag to the paper sleeve in this way, it is not necessary to touch the flexible packaging bag directly by hand, so heat insulation can be imparted, and the side seal part of the flexible packaging bag does not touch the hand, so cut the hand There is no fear.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the trapezoidal side plate is formed with a vertical fold line that bisects the trapezoidal side plate. This is a paper sleeve for a soft packaging bag with a plug member.

  Thus, according to the second aspect of the present invention, since the trapezoidal side plate is formed with a vertical fold line that bisects the trapezoidal side plate, the paper sleeve is folded and stored. And saves storage space. Moreover, when it sets with a flexible packaging bag, the angle of a mountain shape can be adjusted and a flexible packaging bag can be fixed firmly.
