First, the crease lines 24, 26, 28, and 30 are each normally folded at 90 ° to form a rectangular box. The flaps 156 and 174 are normally folded at 90 ° with the crease lines 158 and 176 at one end of the box, and the inner bottom cover piece 148 is normally folded at 90 ° with the crease line 150. Thereafter, glue 182 is applied to the back surface of the outer bottom cover piece 166, and the glue 182 is applied linearly along the end of the outer bottom cover piece 166 opposite to the crease line 168. Then, the crease line 168 is folded forward at 90 °. Thereby, the back surface of the outer bottom cover piece 166 is glued to the surface of the inner bottom cover piece 148 to form a bottom plate.

  In this state, put the product inside. Then, the flaps 152 and 170 are normally folded at 90 ° by the crease lines 154 and 172, the inner upper cover piece 140 is normally folded by 90 ° by the crease line 142, and the insertion piece 144 is further folded by the crease line 146. It is inserted into the back surface of the side surface 18 and locked. Thereafter, the paste 184 is applied to the back surface of the outer upper lid piece 160, and the adhesive 184 is applied linearly along the end of the outer upper lid piece 160 opposite to the crease line 162. Then, the crease line 162 is normally folded at 90 °. Thereby, the back surface of the outer upper lid piece 160 is glued to the surface of the inner upper lid piece 140 to form a lid portion, and the packaging box 136 is closed as shown in FIG.

  Next, a method for opening the packaging box 136 will be described. When opening the packaging box 136, the inner side of the breaking line 164 for opening the side surface 18 is pushed, and the side surface 18 and the outer upper lid piece 160 are cut. Then, the outer upper cover piece 160 divided from the side face 18 is lifted up. When the inner side of the breaking line 164 for opening is pushed, the insertion piece 144 inserted into the back surface of the side surface 18 is also pushed, the engagement with the side surface 18 is released, and when the outer upper lid piece 160 is lifted, The glued inner upper lid piece 140 is also lifted, opened as shown in FIG. 8, and the product inside can be taken out. After using a part of the product, when the remaining product is put in the packaging box 136 again and stored, the inner lid piece 140 is folded forward at 90 ° with the crease line 142, and the insertion piece 144 is further creased. It can be forward-folded at 146, inserted into the back surface of the side surface 18 and locked, and resealed.
