Next, the action when the top plate 50 is folded in half will be described in detail. 7 to 9, the display of the contents C is omitted.
First, as shown in FIG. 7A, the front side of the top plate 50 is lifted somewhat. Then, as shown in FIG. 7B, the top side of the arc-shaped cut line 51 a is lightly tapped with, for example, a finger from the back side of the top plate 50, and the top side of the advertising unit 51 is separated from the rear top plate 501.

Subsequently, the top of the separated advertising unit 51 is picked with a finger, and the advertising unit 51 is lifted upward. Then, the advertising unit 51 is gradually separated from the rear top plate 501 toward the end of the arcuate cut line 51a in accordance with the pulling up operation. In this process, when the position to be separated reaches the second folding lines L52 and L52, the front top plate 502 is bent with respect to the rear top plate 501 along the second folding lines L52 and L52 as shown in FIG. 7B. In other words, the force acting on the front top plate 502 when the advertising unit 51 is pulled upward is suitably released by the bending of the second folding lines L52 and L52. This prevents the front top plate 502 from being bent, and the left and right side edges 502b of the front top plate 502 are also maintained in a straight line.

Then, when the advertising unit 51 is further lifted upward, as shown in FIG. 7C, the separation position of the advertising unit 51 reaches the end of the arcuate cut line 51a, and the second folding lines L52 and L52 described above. In addition to the bending, the front top plate 502 is bent at the first folding lines L51 and L51. That is, the force acting on the front top plate 502 when the advertising part 51 is lifted upward is suitably released by the two front and rear bents of the first folding lines L51 and L51 and the second folding lines L52 and L52. Thereby, the curvature of the front top plate 502 is further prevented, and the left and right side edges 502b of the front top plate 502 are also maintained in a straight line.

Thereafter, as shown in FIG. 8A, the top plate 50 is folded in two along the first folding lines L51 and L51. In the present embodiment, the front end portion 502a of the front top plate 502 is located above the upper surface C1 (see FIG. 6 (b)) of the stored article C in a state where it is folded in two at the first folding lines L51 and L51. It is set so as to have a positional relationship. That is, the operation for folding in half can be performed above the container C without interfering with the container C (without contact). Therefore, it is possible to prevent the container C from falling on contact with the container C or damaging the package by an operation when folding in half.

Thereafter, the front top plate 502 is slid downward relative to the rear top plate 501 as indicated by an arrow in FIG. 8A, and the front end portion 502a of the front top plate 502 is moved to the rear wall as shown in FIG. 8B. It latches in the 30

notch parts

47 and 47. FIG. In this case, the force acting on the front top plate 502 is preferably released by the two front and rear first folding lines L51 and L51 and the second folding lines L52 and L52, and as a result, the front top plate 502 is prevented from bending. That is, the front top plate 502 is slid and moved in the substantially vertical direction while the two-fold state is flexibly held by the two front and rear first folding lines L51 and L51 and the second folding lines L52 and L52. Thereby, the front top plate 502 can be suitably inserted into a narrow space between the rear top plate 501 and the accommodation C. Further, it is possible to suitably prevent the front top plate 502 from being wrinkled or broken during insertion.

As described above, the packaging box 1 can be used as a display tray in which the advertising unit 51 is erected.

According to the packaging box 1 of the present embodiment described above, the second folding line is formed by folding the rear top plate 501 and the front top plate 502 along the first folding lines L51 and L51 during the storefront display in which the rear top plate 501 and the front top plate 502 are raised. L52 and L52 can be preferably used for folding in half. That is, it is possible to suitably absorb the distortion (curvature) of the front top plate 502 that occurs when standing by the two folding lines of the first folding lines L51 and L51 and the second folding lines L52 and L52.
Accordingly, it is possible to obtain the packaging box 1 that can hardly display wrinkles and creases in the top plate 50 at the time of store display and can display the contents C with good appearance.

Further, since the top plate 50 is folded in two at the second folding lines L52 and L52 and covers the lower rear cut line L42 of the rear wall 30 with the front top plate 502, it covers a wide range of the rear surface of the rear wall 30. The contents C can be displayed nicely.

Also, since the

notches

47 and 47 for locking the front top plate 502 are provided on the rear wall 30, the standing state of the front top plate 502 can be suitably maintained. That is, since the front top plate 502 is inserted into the

notches
