And. The front piece portion 21 and the rear piece portion 22 are integrally formed of a single sheet of paper.

  The auxiliary piece 3 is in the form of a piece, and is folded at the boundary portion b2 with the bag body 1 in the packaging state (H) and before the extended piece 2 is bonded to the outer surface gm of the bag body 1. , Which can be inserted into the accommodation space sp. The auxiliary piece 3 is provided integrally and continuously with the bag body 1. In this embodiment, as shown in FIGS. 2 and 3, the auxiliary piece 3 extends upward from the right half portion 11 </ b> R of the front paper 11 and the right half portion 12 </ b> R of the rear paper 12 in the bag body 1. . That is, as shown in FIG. 2, the auxiliary piece 3 is arranged so as to be biased to the right in the front view in the pre-packaging state (M). The auxiliary piece 3 includes a front auxiliary piece portion 31 having a substantially trapezoidal shape extending from the right half portion 11R of the front paper 11, and a rear auxiliary piece portion having a substantially trapezoidal shape extending from the right half portion 12R of the rear paper 12. 32. The front auxiliary piece 31 and the rear auxiliary piece 32 are integrally formed of a single sheet of paper.

  The extension piece 2 and the auxiliary piece 3 described above are arranged substantially symmetrically with respect to the bag body 1. In this embodiment, the extending piece 2 is described as being located on the left side with respect to the bag body 1, but it is needless to say that the embodiment is not limited to this mode. For example, the extended piece 2 may be positioned on the right side with respect to the bag body 1. Similarly, in this embodiment, the auxiliary piece 3 is described as being located on the right side with respect to the bag body 1, but it is needless to say that the embodiment is not limited to this mode. For example, the auxiliary piece 3 may be positioned on the left side with respect to the bag body 1.

  Next, with respect to this packaging bag A, referring to FIGS. 4 to 7, one mode of transition from the pre-packaging state (M) shown in FIGS. 2 and 3 to the packaging state (H) shown in FIGS. 1 and 7 will be described. I will explain.

  First, as shown in FIG. 4, the opening K of the bag body 1 is opened, and the article is put into the accommodation space sp. More specifically, the upper ends tl of the left side edges 11b and 12b of the front paper 11 and the rear paper 12 and the upper ends tr of the right side edges 11c and 12c of the front paper 11 and the rear paper 12 are combined. By making it approach in the approaching direction, the opening K of the bag body 1 is opened, and the article can be put into the accommodation space sp.

  Next, as shown in FIG. 5, the auxiliary piece 3 is bent at the boundary portion b <b> 1 with the bag body 1, and the auxiliary piece 3 is inserted into the accommodation space sp. By doing in this way, the auxiliary piece 3 and a part of the bag body 1 are overlapped in the vicinity of the upper end edges 11d and 12d (near the boundary portion b1) of the right half portions 11R and 12R of the front paper 11 and the rear paper 12. As a result, the shape of the opening K is stabilized. For this reason, it becomes easy not only to put articles into the accommodation space sp, but also to facilitate the bonding operation of the extended piece 2 to the bag body 1 performed thereafter.

  Thereafter, as shown in FIG. 6, the upper ends tl of the left side edges 11b and 12b of the front paper 11 and the rear paper 12 and the upper ends tr of the right side edges 11c and 12c of the front paper 11 and the rear paper 12 are used. Are brought close to the position where they substantially touch each other. In other words, the boundary part b2 between the auxiliary piece 3 and the bag body 1 is brought close to the boundary part b1 between the extending piece 2 and the bag body 1 facing each other. At this stage, the bag body 1 is greatly deformed from the flat sheet-like state (M) in the initial state, and takes a three-dimensional shape.

  More specifically, the front paper 11 and the rear paper 12 are deformed flexibly from the substantially flat plate shape in the pre-packaging state (M), and the three-dimensional shape of a substantially regular tetrahedron, that is, four congruent positive shapes. The shape approximates a tetrahedron with a triangular surface. As shown in FIG. 2, the left half portion 11L of the front paper 11 is bent along a line F1 connecting the middle portion in the left-right direction of the upper end edge 11d and the left end portion of the lower end edge 12a of the front paper 11. . The right half portion 11R of the front paper 11 is bent along a line F2 connecting the middle portion in the left-right direction of the upper end edge 11d and the right end portion of the lower end edge 12a. As shown in FIG. 3, the left half 12L of the rear paper 12 is a line F3 connecting the middle portion in the left-right direction of the upper edge 12d and the right edge of the lower edge 12a (right edge in the rear view). Will bend along. The right half portion 12R of the rear paper 12 is bent along a line F4 connecting the middle portion in the left-right direction of the upper edge 12d of the rear paper 12 and the left end portion (left end portion in rear view) of the lower edge 12a. .

  Finally, as shown in FIG. 7, by bonding the extending piece 2 to the outer surface gm of the bag body 1, the packaging bag A has a packaging state (H) that has a substantially tetrahedral shape as a whole. I will take it. In addition, various adhesion | attachment means can be applied for adhesion | attachment with the extension piece 2 and the bag main body 1. FIG. For example, the extension piece 2 and the bag body 1 may be bonded via an adhesive seal sh as shown in FIG. 1 or may be bonded by various adhesives. Alternatively, it is possible to bond the extension piece 2 and the bag body 1 by forming a slit in one of the extension piece 2 and the bag body 1 and forming a cut and raised piece that engages with the slit in the other. It may be.

  As described above, the paper packaging bag A according to the present embodiment includes the front paper 11 having a substantially rectangular shape in front view and the rear paper 12 having substantially the same shape as the front paper 11. The lower end edges 11a and 12a, the left side edge edges 11b and 12b, and the right side edge edges 11c and 12c in the paper 11 and the rear paper 12 are connected to each other, and the front paper 11 and the rear paper 12 And a bag body 1 configured to be capable of forming an article space between the left and right half portions 11L and 12L of the front paper 11 and the rear paper 12 and extending from upper end edges 11d and 12d. An extension piece 2 is provided. Then, the upper end tl of the left side edge 11b, 12b and the upper end tr of the right side edge 11c, 12c are brought close to each other, and the extension piece 2 is bonded to the outer surface gm of the bag body 1. The packaging state (H) in the shape of a substantially regular tetrahedron can be taken. For this reason, the packaging bag A which can perform suitably the operation | work which forms a packaging state (H) can be provided.

  That is, the extended piece 2 is extended from the upper end edges 11d and 12d of the left half portions 11L and 12L of the front paper 11 and the rear paper 12. In other words, the extension piece 2 is positioned with respect to the bag body 1. For this reason, the user can intuitively understand the application and usage direction of the extension piece 2, and can suitably perform the operation of forming the packaging state (H).

  An auxiliary piece 3 is provided that extends from the upper edge of the right half portion 12 of the front paper 11 and the rear paper 12 and is arranged in the storage space sp in the packaging state (H). For this reason, the auxiliary piece 3 reinforces the opening K of the bag body 1 and stabilizes the shape of the opening K in the process of shifting from the pre-packaging state (M) to the packaging state (H). In addition, the auxiliary piece 3 is positioned so as to be biased with respect to the bag body 1, similarly to the extended piece 2. For this reason, the user can intuitively understand the purpose and direction of use of the auxiliary piece 3 and can suitably perform the operation of forming the packaging state (H).

  Since the extension piece 2 and the auxiliary piece 3 are provided integrally with the bag body 1, the extension piece 2 and the auxiliary piece 3 can be handled integrally with the bag body 1, and suitably suppress an increase in the number of parts. Will be able to.

  The present invention is not limited to the embodiment described in detail above.

  The packaging bag can be set to an appropriate size, and is not limited to that shown in the present embodiment.

  The auxiliary piece is not necessarily an essential component. That is, the present invention can achieve the intended purpose as long as it has a bag body and an extending piece.

  In the above-described embodiment, the extension piece is positioned on the left side with respect to the bag body and the auxiliary piece is positioned on the right side with respect to the bag body. However, the embodiment is not limited to this mode. That is, the extension piece may be positioned on the right side with respect to the bag body and the auxiliary piece may be positioned on the left side with respect to the bag body.

  The extending piece and the auxiliary piece may be formed separately from the bag body and connected to the bag body by an appropriate method.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
