The length of the pair of width surface panels 2a and 2b in the left-right direction can be appropriately set based on the size of the papers accommodated in the box body 30, but for example, when the papers are newspapers, the length is 21 cm. It can be more than 28 cm or less.

The pair of width surface panels 2a and 2b are defined by a pair of easy-to-break lines 16 extending downward from the upper edge and a first easy-to-bend line 17 connecting the lower ends of the pair of easy-to-break lines 16 and overlap the inner surface. It has a folded piece 18 which is folded back as described above. As shown in FIG. 2, in the box body 30, a recess 34 is formed in the pair of width surface panels 2a and 2b by bending the folded piece 18.

The folded piece 18 is a connecting portion 18a that is bent in parallel with the pair of bottom flaps 3a and 3b and the pair of in-bottom flaps 4a and 4b in a state of being assembled in the box body 30, and the folded piece 18 is continuous from the connecting portion 18a. It has a first folded portion 18b that is folded on the inner surface of the width surface panels 2a and 2b having the above, and a second folded portion 18c that is continuous from the first folded portion 18b and folded on the upper surface of the bottom portion 31. A third easy-to-fold line 19 is formed at the boundary line between the connecting portion 18a and the first folded portion 18b. A fourth easy-to-fold line 20 is formed at the boundary line between the first folded portion 18b and the second folded portion 18c. The shape of the folded pieces 18 provided on the width surface panels 2a and 2b can be substantially the same as the shape of the folded pieces 13 provided on the length surface panels 1a and 1b.

As shown in FIG. 2, the pair of width surface panels 2a and 2b have a notch 35 at the bottom of the recess 34 formed by the folding of the folded piece 18. As shown in FIG. 3, in the box sheet 10, the end portion of the string S can be easily temporarily fixed by the pair of width surface panels 2a and 2b having the notch 35. As a result, the string S can be prevented from bulging to the outside of the pair of width surface panels 2a and 2b, and unintended catching of the string can be suppressed. The specific shape of the notch 35 provided in the width surface panels 2a and 2b can be the same as that of the notch 33 provided in the length surface panels 1a and 1b.

(Bottom flap)
One bottom flap 3b (hereinafter, also referred to as "first bottom flap 3b") is a rectangular main body 21a extending from the lower edge of the length surface panel 1b and a projecting piece extending from the tip edge of the main body 21a. It has 21b and. The other bottom flap 3a (hereinafter, also referred to as “second bottom flap 3a”) has a recess 22a at its tip edge that is engaged with the projecting piece 21b. On both sides of the pair of bottom flaps 3a and 3b in the width direction, second easy-to-bend lines 21c and 22c extending inwardly in the width direction from the base end side toward the tip end side are provided.

The procedure for engaging the pair of bottom flaps 3a and 3b will be described. First, in a state where the pair of bottom flaps 4a and 4b are bent substantially vertically inward, the second bottom flap 3a is bent substantially vertically inward, and the first bottom flap 3b is further bent inward on the outer surface side of the second bottom flap 3a. Fold it in. Then, the first bottom flap 3b is pushed in while being pressed against the outer surface of the second bottom flap 3a. At this time, the pair of second easy-to-bend lines 21c provided on the first bottom flap 3b and the pair of second easy-to-bend lines 22c provided on the second bottom flap 3a are appropriately bent to form the first bottom flap 3b. Can be easily pushed in. After pushing the tip edge of the projecting piece 21b of the first bottom flap 3b until it passes through the recess 22a of the second bottom flap 3a, the pushing of the first bottom flap 3b is released. As a result, the reaction force of the sheet material pushes back the first bottom flap 3b and the second bottom flap 3a, and in this process, the projecting piece 21b enters the inside of the recess 22a. As a result, the first bottom flap 3b and the second bottom flap 3a are engaged with each other.

In the box sheet 10, the bottom portion 31 of the box body 30 is assembled in this way, so that the bottom portion 31 can be easily held parallel to the installation surface. Therefore, the papers P can be more stably housed in the box body 30, and the space between the bottom portion 31 of the box body 30 and the installation surface can be stably provided.

Specifically, the box sheet 10 is provided with an opening 21d at a portion including a boundary line between the main body 21a and the convex portion 21b of the first bottom flap 3b, and is provided at the bottom edge of the concave portion 22a of the second bottom flap 3a. A notch 22d is provided. The through hole 31a is defined by the opening 21d and the notch 22d. By being provided in this way, the through hole 31a penetrates the bottom edge of the recess 22a. The through hole 31a is preferably provided in the central portion of the bottom portion 31.

As shown in FIGS. 3, 6 and 7, the box sheet 10 is provided with a through hole 31a at the bottom 31 of the box body 30, so that the box sheet 10 penetrates the excess portion of the string S loose in the box body 30. It can be pulled out from the hole 31a into the space between the bottom 31 and the installation surface and held together in this space. In the box sheet 10, since the through hole 31a penetrates the bottom edge of the recess 22a, the through hole 31a can be provided in the portion where the pair of bottom flaps 3a and 3b overlap. As a result, it is possible to prevent the strength of the bottom portion 31 from being reduced due to the through hole 31a, and it is easy to stably accommodate the papers P in the box body 30. Further, since the through hole 31a penetrates the bottom edge of the recess 22a, the string S drawn out from the through hole 31a can be easily guided to the first bottom flap 3b side while being guided by the bottom edge of the recess 22a. As a result, the string S can be easily pulled out into the space between the bottom 31 of the box body 30 and the installation surface of the box body 30.

(Flap in the bottom)

It can be easily stacked and stored in the box body 30. The box sheet 10 is provided continuously on the lower edges of the pair of length surface panels 1a and 1b, and includes a first leg piece 5 that projects downward from the bottom of the box body 30 in the assembled state. A space can be provided between the bottom 31 of the box body 30 and the installation surface of the box body 30. Therefore, in the box sheet 10, for example, two strings S are occluded in a cross shape on the bottom portion 31 of the box body 30, and the ends of the respective strings S are the length surface panels 1a and 1b and the width surface panels 2a. In the state of being pulled out above 2b, the surplus portion of the string S loose in the box body 30 can be pulled out from the through hole 31a into the space between the bottom 31 and the installation surface and held together in this space. .. Therefore, the box sheet is excellent in the function of holding the strings together.

The box sheet 10 extends from the lower edges of the pair of width surface panels 2a and 2b, and is arranged on the upper side of the pair of bottom flaps 3a and 3b in the assembled state, and the pair of bottom flaps 4a and 4b and the pair of width surfaces. Since the second leg piece 6 which is continuously provided on the lower edges of the panels 2a and 2b and projects downward from the bottom portion 31 in the assembled state is provided, the paper P can be more stably housed in the box body 30. At the same time, the space between the bottom portion 31 of the box body 30 and the installation surface of the box body 30 can be stably provided.

According to the box sheet 10, the strings contained in the space between the bottom 31 and the installation surface by pulling up the end of the string S in a state where the papers P are stacked in the box body 30. The surplus portion of S can be pulled upward. As a result, as shown in FIG. 8, the papers P can be easily bound by the string S, and the papers P can be easily taken out from the box body 30.
