Each of the pair of second long side wall portions 7 is connected to two side portions extending in parallel with the longitudinal direction of the bottom wall portion 2 among the four side portions of the horizontal wall portion 6b via a fold line S6.

  The first longitudinal side wall 3 is formed with a notch piece 3a and a first slit groove 3c. The cutout piece 3 a is formed by cutting out a part of the first longitudinal side wall portion 3. The cutout piece 3 a has a substantially rectangular shape, and is formed at one end portion in the longitudinal direction of the first longitudinal side wall portion 3. One of the two sides extending in the vertical direction of the cutout piece 3 a is connected to the first longitudinal side wall 3, and the other three sides are separated from the first longitudinal side wall 3. And the notch piece 3a can be bend | folded in the thickness direction of the 1st longitudinal side wall part 3 by using one (base end part) of the two side parts extended to an up-down direction as a fulcrum. Further, an insertion hole 3b is formed in the first longitudinal side wall portion 3 by cutting out (deleting) the tip portion of the cutout piece 3a. The outer edge of the insertion hole 3b has a semicircular shape when viewed from the thickness direction of the first longitudinal side wall 3. The insertion hole 3b has a size that allows a human finger (for example, a thumb) to be inserted.

  The said 1st slit groove | channel 3c is formed at intervals with respect to this notch piece 3a in the left-right direction (direction along fold line S1 of the 1st longitudinal side wall part 3) of FIG. The first slit groove 3c is formed in a rectangular shape that opens to the lower side in FIG. 1 in the unfolded state (the state in FIG. 1). That is, the first slit groove 3c is formed to open upward in an assembled state (that is, a state where the first longitudinal side wall portion 3 stands up with respect to the bottom wall portion 2). The end portion on the open side of the first slit groove 3c is formed in a divergent shape in which the groove width increases toward the open side when viewed from the thickness direction of the first longitudinal side wall portion 3. That is, the two edge portions on the open side of the first slit groove 3c are chamfered. In this embodiment, the chamfer angle is approximately 45 °.

  The second longitudinal side wall portion 7 has a through hole 7a and a second slit groove 7b. The through hole 7a is formed in a long hole shape extending in parallel with the fold line S6. The through-hole 7a is formed so as to be adjacent to the inside of the package of the notch piece 3a in the assembled state. The second slit groove 7b is formed in a rectangular shape that opens to the lower side of FIG. That is, the second slit groove 7b is formed so as to open downward in the assembled state.

  When assembling the assembly-type package 1, first, the pair of first long side wall portions 3 are valley-folded along the fold line S <b> 1 (folded toward the front side in FIG. 1) with respect to the bottom wall portion 2. Stand up.

  Thereafter, one short side wall portion 4 (the short side wall portion 4 on the right side in FIG. 1) is valley-folded along the fold line S2 (folded toward the front side in FIG. 1) to stand. Then, after the inclined wall portion 5a of the one side upper wall portion 5 is valley-folded along the fold line S3 so as to be along the inclined side portion 3d of the first longitudinal side wall portion 3, the horizontal wall of the one side upper wall portion 5 is obtained. The portion 5b is valley-folded along the fold line S4 and arranged substantially parallel to the bottom wall portion 2.

  Further, the second longitudinal side wall portion 7 is valley-folded along the fold line S <b> 6 (folded toward the front side of the paper) and raised with respect to the horizontal wall portion 6 b of the other side upper wall portion 6. Then, the other short side wall part 4 (the short side wall part on the left side in FIG. 1), the adjustment margin 6a of the other side upper wall part 6, and the horizontal wall part 6b of the other side upper wall part 6 are folded. The valley is folded along the line S2, the fold line S3, and the fold line S5 so that the other side upper wall portion 6 faces the bottom wall portion 2, and the second slit groove 7b of the second longitudinal side wall portion 7 is positioned. Is aligned with the position of the first slit groove 3c of the first longitudinal side wall 3 (see FIG. 2). And the 2nd slit groove 7b is engaged with the 1st slit groove 3c so that the 2nd longitudinal side wall part 7 and the 1st longitudinal side wall part 3 may cross | intersect X shape (refer FIG. 3).

  Specifically, the portion on the cutout piece 3a side of the first longitudinal side wall portion 3 with respect to the first slit groove 3c is located on the outer side of the packaging body with respect to the second longitudinal side wall portion 7, and the first longitudinal side wall portion 3 The second slit groove 7b is engaged with the first slit groove 3c so that the portion on the opposite side of the notch piece 3a with respect to the slit groove 3c is located on the inner side of the packaging body with respect to the second longitudinal side wall portion 7. .

  Then, after engaging the second slit groove 7b with the first slit groove 3c, when the notch piece 3a is pushed and bent inside the packing body with a finger, the notch piece 3a is formed in the through hole 7a of the second longitudinal side wall portion 7. It penetrates and engages (see FIG. 4). Thereby, the 2nd longitudinal side wall part 7 and the 1st longitudinal side wall part 3 are connected firmly, and the assembly of the assembly-type package 1 is completed.

  As described above, in the above embodiment, when assembling the assembling-type package 1, the notch piece 3 a of the first longitudinal side wall 3 is bent and engaged with the through hole 7 a of the second longitudinal side wall 7. The connection rigidity in the longitudinal direction (X direction in FIG. 5) between the first longitudinal sidewall portion 3 and the second longitudinal sidewall portion 7 can be sufficiently ensured. Further, when the assembling type packaging body 1 is assembled, by engaging the second slit groove 7 b of the second longitudinal side wall portion 7 with the first slit groove 3 c of the first longitudinal side wall portion 3, Since the first longitudinal side wall portion 3 intersects with the X shape, the first longitudinal side wall portion 3 and the second longitudinal side wall portion are compared with the case where the slit grooves 3c and 7b are not provided as shown in FIG. The connection rigidity in the thickness direction with the portion 7 (the Y direction in FIG. 5 and the lamination direction of the side wall portions 3 and 7) can be remarkably improved.

  Moreover, in the said embodiment, the insertion hole 3b is formed in the 1st longitudinal side wall part 3 by excising a part by the side of the front end of the notch piece 3a. Therefore, the operator can easily bend the notch piece 3a toward the inside of the package by inserting a finger into the insertion hole 3b. Therefore, the bending work of the notch piece 3a can be facilitated as compared with the case where the insertion hole 3b is not provided.

  Moreover, in the said embodiment, the edge part of the open side of the 1st slit groove | channel 3c formed in the 1st longitudinal side wall part 3 sees the groove width so that this open side sees from the thickness direction of the 1st longitudinal side wall part 3. It is formed in a widening shape. Therefore, the second slit groove 7b of the second longitudinal side wall portion 7 can be smoothly engaged with the first slit groove 3c.
