[Configuration of box 1]
As shown in FIGS. 1, 3, and 4, the box 1 is a rectangular parallelepiped-shaped cardboard box that can store one four-go bottle, and has a square cylindrical side surface 5 and an upper part of the side surface 5. The upper flap part 6 opens and closes the opening at the bottom of the side part 5, and the lower flap part 7 opens and closes the opening at the bottom of the side part 5. At the time of delivery, as shown in FIG. 1, after the four-go bottle is packed in a box 1, this box 1 is stored in a cosmetic case 100. For convenience of the following explanation, the side of the box 1 where the upper part of the 4-go bottle is arranged will be referred to as the upper side, and the side where the lower part of the 4-go bottle will be arranged will be called the lower side.

The box 1 is formed into a rectangular parallelepiped by assembling the flat cardboard members 10 shown in FIG. The corrugated cardboard member 10 is constructed by making incisions, cutting, or perforations in a cardboard base paper. In addition, in FIG. 2, the portion that becomes the crease is indicated by a chain double-dashed line.

The corrugated cardboard member 10 includes a front part 11, a right side part 12, a left side part 13, and a back part 14, which are four rectangular side plates constituting the side part 5 of the box body 1. For convenience of explanation below, in the flat cardboard member 10 shown in FIG. 2, the long direction of the rectangles forming the four side plates will be referred to as the vertical direction, and the short direction will be referred to as the horizontal direction. The side surface portion 5 is divided into four side plates by three folds, and is laterally arranged in the order of a left side surface portion 13, a front surface portion 11, a right side surface portion 12, and a back surface portion 14. Since the long sides of the four side plates correspond to the folds, the three folds are equally spaced and lined up in parallel. In addition, for convenience of the following explanation, in the horizontal direction, the side on which the left side part 13 is arranged with respect to the front part 11 is called the left side, and the side on which the right side part 12 is arranged is called the right side. Further, in the vertical direction, the side where the bottom of the 4-go bottle is placed is called the lower side or lower side, and the side where the upper part of the 4-go bottle is placed is called the upper side or upper side.

In the four side plates of the box body 1, the front part 11 is arranged on the right side of the left side part 13. The right long side of the left side part 13 becomes a fold between the left side part 13 and the front part 11. Similarly, the front part 11 is arranged on the left side of the right side part 12. The left long side of the right side part 12 becomes the fold between the right side part 12 and the front part 11. Further, a back surface portion 14 is arranged on the right side of the right side surface portion 12. The right long side of the right side part 12 becomes the fold between the right side part 12 and the back part 14.

Since the front part 11, the right side part 12, the left side part 13, and the back part 14 have the same short side length, the openings at both ends of the side part 5 are square. Further, the length of the short side is set to be equal to or slightly longer than the diameter of the bottom of the four-go bottle plus the thickness of four cardboard members 10.

In this embodiment, the length of the long side of the left side portion 13 is set to be several centimeters longer than the height of the four-go bottle. The lengths of the long sides of the front part 11 and the back part 14 are set to be the length of the long sides of the left side part 13 plus the thickness of four corrugated cardboard members 10. The length of the long side of the right side part 12 is set to the length of the long side of the left side part 13 plus the thickness of two cardboard members 10. That is, the short side of the left side portion 13 extends from a portion closer to the center by the thickness of the two cardboard members 10 with respect to both ends of the left long side of the front portion 11 . Similarly, the short side of the right side portion 12 extends from a portion closer to the center by the thickness of one corrugated cardboard member 10 with respect to both ends of the right long side of the front portion 11 . Further, the short side of the right side portion 12 extends from a portion closer to the center by the thickness of one corrugated cardboard member 10 with respect to both ends of the left long side of the back side portion 14. In addition, the length of the long side of the right side part 12 is set to be longer than the length of the long side of the left side part 13 by the thickness of the two cardboard members 10.

Therefore, the purchaser can easily release the fitted state between the engaging parts 13e, 16a, 14h and the notches 14e, 14j, 15a by inserting their fingers into the semicircular holes 14f, 14k, 15b. become. Furthermore, by releasing the fitted state between the engaging parts 13e, 16a, 14h and the notches 14e, 14j, 15a, the box 1 can be expanded. This facilitates unpacking by the purchaser.

Furthermore, according to the present embodiment, the box 1 is assembled by folding in the folds in the corrugated cardboard member 10 and fitting the engaging portions 13e, 16a, 14h into the notches 14e, 14j, 15a. Work becomes easier.

Moreover, according to the present embodiment, the corners of the front part 11, right side part 12, left side part 13, and back part 14, the top flap 15, the bottom flap 16, the upper right flap 17, the lower right flap 18, the upper left flap 19, and Corners of the lower left flap 20, corners of the tongue pieces 11a, 12a, 13a, 14a, 17a, 19a, corners of the holding parts 12b, 13b, corners of the regulating parts 11b, 14b, and corners of the engaging parts 13e, 13e. The corner portions and the corner portions of the engaging portions 14h and 16a are formed into arc shapes. Therefore, the number of sharp parts in the cardboard member 10 is reduced, and safety can be ensured during assembly work or unpacking work. Moreover, since interference between the corners is reduced during assembly, workability in assembling the box 1 can be improved.

Further, according to this embodiment, the notch 14e and the recess 14d of the back surface part 14 and the engagement part 13e and the extension part 13d of the left side surface part 13 have the same shape and are positioned at the same height in the vertical direction. Therefore, when manufacturing the corrugated board member 10 by making cuts in the corrugated board, the notch portion 14e and the recessed portion 14d, and the engaging portion 13e and the extending portion 13d can be formed at the same time. Thereby, waste of material when manufacturing the corrugated board member 10 can be reduced.

Although the box 1 of this embodiment has been described above, this embodiment is not limited to the above-described embodiment. For example, the box 1 of the embodiment described above is for packing a 4-go bottle, but it can also be applied to a 1-sho bottle or a wine bottle. Further, in the above-described embodiment, a five-layer cardboard box called a double flute and a thickness of 8 mm is used, but it is also possible to use a cardboard box of other specifications. However, in order to improve the cushioning properties, it is desirable that the cardboard be made up of five or more sheets.
