  In FIG. 1, the length in the direction (left-right direction) perpendicular to the center core Bc of the front side plates 12L, 12R and the rear side plates 13L, 13R is the length L1 in the direction (front-back direction) along the center core Bc of the bottom plate 11. Half (L1 / 2). The length in the direction perpendicular to the center core Bc of the bottom side plates 11L and 11R (left and right direction) and the length along the direction (left and right direction) along the center core Bc of the top side plates 31L and 31R are as follows. This is a half (L2 / 2) of the length L2 in the direction (front-rear direction) along the center core Bc of the plate 13.

  In FIG. 4, the lid 30 is formed by bending a pair of top side plates 31L and 31R, a front engagement piece 32f, and a rear engagement piece 32g at right angles to the top plate 31 along the folds 31f and 31g. Inverted U-shape. In the main body 10, the notches 15c, 15d, 16c, 16d of the front side plates 12L, 12R and the rear side plates 13L, 13R face each other, and the front side plates 12L, 12R and the rear side plates 13L, 13R are overlapped with the bottom side plates 11L, 11R. ing. Further, in the main body 10, the front folded piece 12A and the rear folded piece 13A are bent inward at right angles along the folds 12f and 13g and face each other.

  In FIG. 4, when the lid 30 with the pair of top plates 31L and 31R, the front engagement piece 32f, and the rear engagement piece 32g bent is placed on the upper part of the main body 10, as shown in FIG. It becomes the box 1 which accommodates. At this time, in FIG. 4, the front side engaging piece 32 f and the rear side engaging piece 32 g as the engaging parts are inserted into the front slit 14 f and the rear slit 14 g as the engaged parts of the main body 10, and the top plate 31L and 31R are overlapped on the front side plates 12L and 12R and the rear side plates 13L and 13R. Then, the bottom side plates 11L and 11R and the top side plates 31L and 31R overlap the front side plates 12L and 12R and the rear side plates 13L and 13R due to the length relationship of the respective plates. Further, the notches 15c, 15d, 16c, 16d of the front side plates 12L, 12R and the rear side plates 13L, 13R facing each other and the long holes 33c, 33d of the top side plates 31L, 31R are overlapped to form the handle hole 2. Furthermore, the direction of the center core Bc of the main body 10 and the direction of the center core Bc of the lid 30 are orthogonal to each other.

  As shown in FIG. 5, the box 1 with the main body 10 covered with the lid 30 is wound with the adhesive tape T along the boundary between the top side plates 31L and 31R and the bottom side plates 11L and 11R. Are integrated, and the user can carry a finger inserted into the handle hole 2. Note that the handle hole 2 is not necessarily required.

  In the above description, the front side engagement piece 32f and the rear side engagement piece 32g as the engagement part are inserted into the front slit 14f and the rear slit 14g as the engaged parts of the main body 10, and The direction of the core Bc and the direction of the center core Bc of the lid 30 are set to be orthogonal to each other. However, the relative position between the main body 10 and the lid 30 is determined based on a mark (not shown) attached to the main body 10 and the lid 30, and the orientation of the central core Bc of the main body 10 and the orientation of the central core Bc of the lid 30 are determined. May be orthogonal to each other. Further, the bottom plate 11 of the main body 10 and the top plate 31 of the lid 30 are formed in a rectangular shape, the lid 30 is matched to the rectangular shape of the main body 10, and the relative position between the main body 10 and the lid 30 is determined. Bc and the core Bc of the main body 10 may be orthogonal to each other.

  Next, the strength of the box 1 will be described. 1, 4, and 5, when a downward force P <b> 1 (FIG. 5) is applied from the upper side to the lower side of the box 1, the front plate 12 and a pair of front plates 12 whose center core Bc is along the downward force P <b> 1. The side plates 12L and 12R, the rear plate 13, and the pair of rear side plates 13L and 13R receive the downward force. When the front-rear direction force P2 is applied from the front-rear direction of the box 1, the bottom plate 11 and the pair of bottom side plates 11L, 11R in which the core Bc is along the front-rear direction force P2 receive the front-rear direction force P2. When the left-right direction force P3 is applied from the left-right direction of the box 1, the top plate 31 in which the center core Bc is along the left-right direction force P3 receives the left-right direction force P3.

  Further, the top plate 31 is the only plate with the center core Bc along the left-right force P3. For this reason, the top plate 31 receives the lateral force P3. However, the top plates 31L and 31R and the bottom plates 11L and 11R overlap the front plates 12L and 12R and the rear plates 13L and 13R. You will also receive it on the left and right sides.

  Thus, the box 1 has the core Bc along the direction of the applied force even if it receives force from any of the three directions because the core Bc of the plate forming the box 1 faces in the three directions. It is possible to receive a force with a plate provided with Bc. Moreover, the left-right direction force P3 can be received also on the left and right side surfaces that are overlapped. As a result, the box 1 as a whole has a substantially uniform strength, and is less likely to be deformed regardless of the external force in any direction, and can be stored without damaging the stored item W.

  In addition, the downward force P1 is composed of a front plate 12, a pair of front plates 12L and 12R, a rear plate 13, a pair of rear plates 13L and 13R, and a pair of top plates 31L and 31R. There are many overlapping sheets, mainly on the front and back. For this reason, even if the box 1 is stored repeatedly, the box 1 is hardly deformed and can be stored without damaging the stored item W.

  Furthermore, in the figure which expand | deployed the main body 10 of FIG. 1, the center core Bc has faced the front-back direction. On the other hand, the cardboard B is rolled in the left-right direction in FIG. 1 before being molded. For this reason, when the main body 10 is molded, the main bodies 10 can be continuously modeled parallel to each other in the left-right direction, and the efficiency of molding can be improved.

  Further, the main body 10 shown in FIG. 1 described above is formed of a single cardboard B. However, like the main body 110 shown in FIGS. 6A and 6B, the front plate 12 and the rear plate 13 are formed. The at least one plate and the bottom plate 11 may be formed separately. The front plate 12, the rear plate 13 and the bottom plate 11 are separately formed in a shape separated by the folds 11f and 11g, and are joined pieces extending in the front-rear direction from edges corresponding to the front and rear folds 11f and 11g. The front plate 12 and the rear plate 13 are connected to the bottom plate 11 by 41f and 41g. The joining pieces 41f and 41g may not be formed on the bottom plate 11, but may be formed to extend in the direction of the bottom plate 11 at edges corresponding to the folds of the front plate 12 and the rear plate 13.

  Furthermore, in FIG. 1, the length in the left-right direction of the bottom side plates 11L, 11R of the main body 10 is half the length L2 of the front plate 12 and the rear plate 13 in the front-rear direction (L2 / 2). The front plate 12 and the rear plate 13 may have the same length L2 in the front-rear direction (L2). In FIG. 4, the length in the left-right direction of the top side plates 31L, 31R of the top plate 31 is also half the length L2 in the front-rear direction between the front plate 12 and the rear plate 13 (L2 / 2). The front plate 12 and the rear plate 13 may have the same length L2 in the front-rear direction (L2).
