Moreover, the piece part 56 is provided in a row from the upper end of the side plate part 16 via a broken line, and has a rectangular shape (specifically, a rectangular shape).

  A method for assembling the box A having the above configuration will be described. Note that the margin portion 20 is bonded to the side plate portion 12. Thereby, the side part 10 is cylindrical.

  In the assembled state of the box A of this embodiment, when viewed from the bottom side of the box A, as shown in FIG. 2, the piece 32 overlaps the piece 38, the piece 34 overlaps the piece 32, The piece portion 36 overlaps the piece portion 34 and the piece portion 38 overlaps the piece portion 36 to form the bottom surface portion 30, but from any one of the four pieces of pieces 32 to 38. Even if it bends, the bottom face part 30 can be assembled.

  Below, the case where it begins to fold from the one part 38 is demonstrated as an example. First, the piece portion 38 is bent at a substantially right angle with respect to the side plate portion 18. Next, the piece portion 32 is bent with respect to the side plate portion 12. At that time, a part of the piece 32 overlaps a part of the piece 38. Next, the piece 34 is bent with respect to the side plate 14. At this time, a part of the piece 34 overlaps a part of the piece 32, and a part of the piece 34 overlaps a part of the piece 38. At this stage, the box A is in a state as shown in FIG.

  Thereafter, the piece portion 36 is bent with respect to the side plate portion 16. At this time, the piece portion 36 is pushed so that the piece portion 36 is located below (ie, inside) the piece portion 38. Then, by pushing the piece 36, it is pushed by the piece 36 and the pieces 38 and 34 are also pushed diagonally downward, and further, the piece 32 is pushed obliquely and the piece 32 is also lowered. It will be pushed diagonally. When the piece 36 is pushed deeply and obliquely downward, the state where the piece 36 is in contact with the piece 38 is released at a certain position, and the piece 36 can be pushed deeper.

  And since the state where the piece 38 was pushed by the piece 36 is released, it tries to return to the original state, but at this time, the position where the projecting portion 34c of the piece 34 and the notch K21 face each other. In addition, since the protruding portion 38c of the piece 38 and the cutout portion K11 are in a position facing each other, the protruding portion 34c enters the cutout portion K21, and the protruding portion 38c enters the cutout portion K11. Then, when the state where the piece portion 36 is pushed in is gradually released, the piece portion 38 and the piece portion 34 also return to a state substantially perpendicular to the side plate portion, and the piece portion 34 and the piece portion 38 are As it returns, the projecting portion 34 c comes to be located inside the base end portion 38 a of the piece portion 38, and the projecting portion 38 c comes to be located inside the base end portion 34 a of the piece portion 34. The piece 32 also returns to its original state when pressed from below by the piece 38.

  And when the piece part 36 will be in the original state (namely, a state substantially orthogonal to the side-plate part 16), the assembly state of the bottom face part 30 will be completed. In addition, when the bottom face part 30 is in a slightly dented state as seen from the bottom face side of the box A, the bottom face part 30 can be made flat by pressing the bottom face part 30 from the inner bottom side. When the assembled state of the bottom surface portion 30 is viewed from the inside of the box A, it is as shown in FIG. As shown in FIG. 3, the obtuse angle portion formed by the inclined side portion 32-1 and the inclined side portion 32-2 in the piece portion 32 is locked at a position between the protruding portion 38b and the protruding portion 34c. In addition, the obtuse angle portion formed by the inclined side portion 36-1 and the inclined side portion 36-2 in the piece portion 36 is locked at a position between the protruding portion 34b and the protruding portion 38c, and the bottom surface portion The combined state in is further strengthened.

  In the above description, the case of first bending from the piece 38 has been described as an example, but the pieces 32 to 38 constituting the bottom face 30 of the box A are point-symmetric as shown in FIG. Since it has a shape, the same applies to the case where it is first bent from the piece 34.

  Further, when bending from the piece 32 or the piece 36, it can be assembled in substantially the same manner as described above. For example, when bending from the piece part 32 first, the piece part 32 is bent, then the piece part 34 is bent, and then the piece part 36 is bent. Then, the piece 38 is bent. At this time, the piece 38 is pushed so that the piece 38 is located below (ie, inside) the heel 32. Then, by pushing the piece 38, the piece 38 is pushed by the piece 38, and the piece 32, the piece 34, and the piece 36 are also pushed obliquely downward. When the piece 38 is pushed deeply and obliquely, the state where the piece 38 is in contact with the piece 32 is released at a certain position, and the piece 38 can be pushed deeper. In addition, since the inclined side part 38-11 is formed in the piece part 38 and the inclination angle of this inclined side part 38-11 is an appropriate angle, when pushing in the piece part 38, it is moderate. The state in contact with the piece portion 32 at the correct position is released.

  Since the state where the piece 32 is pushed by the piece 38 is released, when the state in which the piece 38 is pushed is gradually released, an attempt is made to return to the original state. Since the notch K11 is in a position facing each other, the protrusion 34c enters the notch K21, and the protrusion 38c enters the notch K11. Further, the piece 38 and the piece 34 also return to a state substantially perpendicular to the side plate portion, and as the piece 34 and the piece 38 are restored, the projecting portion 34c becomes the base end portion 38a of the piece 38. The protruding portion 38c is positioned inside the proximal end portion 34a of the piece portion 34. The piece 32 returns to its original state when pressed from below by the piece 38, and the piece 36 returns to its original state when pressed from below by the piece 34.

  As described above, the assembled state of the bottom surface portion 30 is completed. In addition, when the bottom face part 30 is in a slightly dented state as seen from the bottom face side of the box A, the bottom face part 30 can be made flat by pressing the bottom face part 30 from the inner bottom side.

  In the above description, the case of first bending from the piece 32 has been described as an example. However, the pieces 32 to 38 constituting the bottom portion 30 of the box A are point-symmetric as shown in FIG. Since it has a shape, the same applies to the case where it is first bent from the piece 36.

  As described above, in the box A of the present embodiment, the bottom portion 30 is assembled by bending in the counterclockwise direction even if it is bent from any one of the pieces 32 to 38, and pushing the last piece deeply. As a result, the bottom portion 30 can be assembled very easily.

  As described above, it is preferable to fold one piece in a counterclockwise direction and push the last piece deeply, but the order of bending the pieces 32 to 38 with respect to the side plate portion is preferred. In any case, if all of the pieces 32 to 38 are pushed into the side portion 10, as a result, the piece is bent counterclockwise as described above, and the last piece is deepened. Since it can be in the same state as the pushed-in state, as a result, the bottom part 30 can be assembled if the pieces 32 to 38 are pushed into the space in the side part 10. However, it is easier for assembly to bend the one part counterclockwise with respect to the side plate part, and in the case of other methods, the operation of pushing the one part into the side part 10 is somewhat difficult. Become.

  That is, since the box A is configured as described above, when viewed from the bottom surface side of the box, the pieces 32 to 38 are bent with respect to the side surface portion in an arbitrary order and pushed into the side surface portion. As a result, a part of the piece 34 overlaps a part of the piece 32, a part of the piece 36 overlaps a part of the piece 34, and a part of the piece 38 becomes a part of the piece 36. By overlapping each other and returning each piece so that a part of the piece 32 overlaps a part of the piece 38, the protrusion 34b in the piece 34 enters the notch K21, and the protrusion in the piece 38 The bottom portion is formed by the pieces 32 to 38 in a state of entering into 38b. In addition, although the inclined side part in each piece part is exposed to the bottom face side of the box, this inclined side part can exhibit the same appearance (appearance on the bottom face side) as a conventional box. In particular, in the box of the present embodiment, the piece 32 and the piece 36 have the same configuration, and the piece 34 and the piece 38 have the same configuration, so that the order of folding the pieces 32 to 38 is arbitrary. It can be said that it becomes possible to have a sex.

  In addition, it can be said that the rounded part provided in the one part 32-38 has fulfill | performed the function which forms a combination state smoothly, when a certain one part combines with another piece part.

  The above description is an example of assembling a broken line as a mountain fold in the unfolded state shown in FIG. 4, but when assembling a folded line as a valley fold in the unfolded state of FIG. Can be easily formed by bending the side plate portion clockwise with respect to the side plate portion. Even in this case, it is preferable to bend the pieces 32 to 38 clockwise, but the order of bending the pieces 32 to 38 is arbitrary.

  In the above description, the portion described as “substantially parallel” may be “parallel”, and the portion described as “substantially vertical” may be “vertical”.

  In the above configuration, it is preferable to display an explanation of the assembling method on either side of the box A. For example, the bottom side of the piece 34 and / or the piece 38 is displayed as “please fold all the bottoms in. It can be assembled from any side.” Alternatively, “please fold one piece constituting the bottom surface in a counterclockwise direction and fold the last piece deeply” is also acceptable.

  In the above description, as shown in FIG. 4, in the unfolded state of the box, the side plate portion 14 is connected to the side end of the side plate portion 12, and the side plate portion 16 is connected to the side end of the side plate portion 14. As described above, the side plate 18 is connected to the side end of the side plate 16, but the side plate 12 is connected from the left end of the side plate 18, and the piece 32 is connected to the lower end of the side plate 12. Further, a configuration in which the piece 52 is continuously provided at the upper end may be adopted. Even in this case, in a state in which the side plate portions 12 to 18 are formed in a cylindrical shape, the side plate portion 12 (first side plate portion) and the side plate portion 14 (second side) connected to the side end of the side plate portion 12 via a broken line. Side plate portion), a side plate portion 16 (third side plate portion) connected to the side end of the side plate portion 14 via a broken line, and a side plate portion 18 (connected to the side end of the side plate portion 16 via a broken line) ( A fourth side plate portion), and the side plate portion 12, the side plate portion 14, the side plate portion 16, and the side plate portion 18 are formed in a cylindrical shape.
