As shown in FIG. 6, the tag pin 210 has an H-like shape as viewed from the side. The stopper portion 211 is supported by the lower surface 111Ab of the bottom inner flap 111A so as not to come out of the through hole 111Aa. The head portion 212 is supported by the upper surface 171 b of the flat plate 171 so as not to slip out of the through hole 171 c.

  Next, an operation procedure for supporting the flat plate 171 having the contents 170 attached thereto by the tag pin 210 will be described.

  First, the through hole 171 c is opened in the flat plate 171 and the through hole 111 Aa is opened in the bottom inner flap 111 A by a sharp punch not shown.

  Next, the stoppers 211 and the legs 213 of the tag pin 210 are inserted into the through holes 171 c of the flat plate 171 to which the contents 170 are attached. Then, the bottom inner flap 111A is folded, and the stopper 211 and the leg 213 of the tag pin 210 are inserted into the through hole 111Aa. Thereby, the edge 171a of the flat plate 171 is supported by the tag pin 210 on the bottom inner flap 111A. Then, the bottom outer flap 112 is bent to be in the state shown in FIG.

  As described above, according to the second embodiment, the flat plate 171 having the contents 170 attached thereto is fixed to the bottom inner flap 111A via the tag pin 210 (fixing member).

  Therefore, the edge 171a of the flat plate 171 to which the contents 170 are attached can be supported on the bottom 110 by a simple operation of penetrating the tag pin 210 through the through holes 171c and the through holes 111Aa. In addition, since the lightweight tag pin 210 is used, an increase in weight of the cardboard box 200 can be suppressed. Further, the size of the tag pin 210 can be appropriately adjusted in accordance with the thickness of the flat plate 171.

  As shown in FIG. 7, in the bottom portion 110 of the cardboard box 300 according to the third embodiment, the bottom inner flap 111 is disposed so as to overlap the bottom outer flap 112. The bottom side inner flap 111 is connected to the width surface 121. The support portion 310 is provided at the lower end portion of the width surface 121.

  As shown in FIG. 8, the support portion 310 includes a first portion 311, a second portion 312, and a third portion 313. The first portion 311 is bent at the lower end 121 a of the width surface 121 and extends upward and obliquely upward as it goes inside. The first portion 311 is an inclined wall portion. The second portion 312 is bent at the tip end 311 a (first broken line 321) of the first portion 311 and extends outward to the width surface 121. The second portion 312 is a lateral wall. The third portion 313 bends at the tip end 312 a (second broken line 322) of the second portion 312 and extends downward along the width surface 121 to the tip end 313 a. The third portion 313 is a vertical wall.

  The support portion 310 is formed in a triangular shape in cross section by the first portion 311, the second portion 312 and the third portion 313. For example, the crossing angle between the second portion 312 and the third portion 313 may be a right angle, and the other two angles may be acute triangles. At the first portion 311, the upper corner 170a (end) of the content 170 is supported.

  Next, a procedure for forming the support portion 310 will be described. First, as shown in FIG. 9, two incisions are made in the bottom inner flap 111 to form a first strip 320 in the central portion in the longitudinal direction. That is, the bottom inner flap 111 is separated into the first strip portion 320, the second strip portion 330, and the third strip portion 340 by the two cuts. The second strip portion 330 and the third strip portion 340 are disposed on both sides of the first strip portion 320 in the longitudinal direction.

  Next, the first belt-like portion 320 is bent to the outside in the arrow direction of FIG. 9 with the first broken line 321 indicated by a dashed dotted line as a boundary. Thereby, the first portion 311 and the second portion 312 are formed. Next, the first band-shaped portion 320 is bent outward in the arrow direction of FIG. 9 with the second broken line 322 indicated by a dashed dotted line as a boundary. Thereby, the third portion 313 is formed. Through the above steps, the support portion 310 shown in FIG. 8 is formed.

  As described above, according to the third embodiment, the support portion 310 is bent at the lower end 121a of the width face 121, and extends upward obliquely upward as it goes inward, and the tip of the first portion 311 A second portion 312 that bends outward at a bend 311a (first broken line 321) to the width surface 121 and a tip that extends downward along the bend width surface 121 at a tip 312a (second broken line 322) of the second portion 312 And a three part 313. The upper end corner 170 a (end) of the content 170 is supported by the first portion 311.

  As shown in FIG. 8, the first portion 311 is an inclined portion extending obliquely upward toward the upper side as it goes inward. The upper end corner 170 a (end) of the content 170 is supported by the first portion 311. Here, when the upper end corner portion 170a abuts on the first portion 311, a reaction force directed obliquely downward from the first portion 311 is input to the upper end corner portion 170a. That is, the first portion 311 supports the upper end corner 170 a by pressing the upper end corner 170 a obliquely downward. Therefore, the contents 170 can be effectively supported.

  Thus, the contents 170 can be supported by a simple operation. Furthermore, since a part of the cardboard box 300 is processed to create the support portion 310, the weight of the cardboard box 300 does not increase. As in the first and second embodiments, the contents 170 may be supported by the support portion 310 in a state where the contents 170 are attached to the flat plate 171.

  The present invention is not limited to the embodiment and the modification. That is, various modifications can be made without departing from the gist of the present invention. For example, in the first embodiment described above, the bent portions 150 are provided at all the four corner portions 140, but the bent portions 150 may not necessarily be provided at all four places.
