The above-mentioned slit portion 152 is formed in the center of the upper and outer flaps 15 .

FIG. 3 is a plan view of section A including the slit section 152 in FIG.
The slit portion 152 has an opening base 15a, a pair of projecting portions 15b, and two pairs of notches 15c.

The opening base 15a is formed as a hole having a width Da and a length La extending in the left-right direction.
The overhanging portions 15b are portions that overhang from the front and rear edges at the left-right center of the opening base 15a so as to approach each other so that the gap is a width Db narrower than the width Da.
The cut 15c is a portion cut with a length Lc further leftward and rightward from both the front and rear corners of the left and right ends of the opening base 15a, respectively. The maximum distance between the left and right ends of the notch 15c is the distance Lb. A portion between a pair of notches 15c spaced apart from each other in the front and back serves as a hook flap 15d.

The approximate dimensions of the slit portion 152 are as follows.
That is, the opening base 15a has a length La of 38 mm and a width Da of 3 mm. The width Db of the gap between the projecting portions 15b, 15b is 1 mm. The length Lc of the notch 15c is 2 mm, and the distance Lb, which is the maximum distance between the left and right ends of the notch 15c, is 42 mm.

FIG. 4 is a two-sided view showing the hook member 2, with (a) being a front view and (b) being a right side view. As shown in FIG. 4, the hook member 2 includes a base plate 21, the previously described hook plate 22, and a connecting portion 23.

The substrate portion 21 is formed into a rectangular plate shape that is long in the left and right directions, and has a length L2c in the left-right direction and a width D2c in the front-rear direction when viewed from above.
The hook plate 22 is formed in the center of the base plate part 21 in a plate shape and extends vertically and horizontally via a connecting part 23.
The hook plate 22 has a length L2a in the left-right direction and a thickness D2a in the front-rear direction.
The hook plate 22 has, as a through hole, a hanging hole 22c in the center thereof, in which an opening 22a extending left and right and a notch 22b cut upward in an arc shape from the left and right center of the opening 22a are integrated.
The connecting portion 23 has a thickness D2b smaller (thinner) than the thickness D2a in the front-rear direction, and a height Ha in the vertical direction.
The base plate portion 21 is connected to the hook plate 22 via a connecting portion 23 so as to extend orthogonally to the hook plate 22 so as to be integrated therewith.

Examples of dimensions of the hook member 2 are as follows, with approximate dimensions.
That is, the hook plate 22 has a length L2a of 42 mm and a thickness D2a of 1.9 mm. The substrate portion 21 has a length L2c of 60 mm and a width D2c of 11 mm. The connecting portion has a thickness D2b of 0.5 mm and a height Ha of 2 mm.

The hook plate 22 can be inserted into the slit portion 152 of the upper and outer flaps 15 while bending the hook flap 15d from the base, and the base plate portion 21 cannot be inserted into the slit portion 152.

With the above-described flap configuration, the box body 1 can be changed from the state shown in FIG. 2 in which the upper and outer flaps 15 are opened and the hook member 2 is removed to the state in which the upper and outer flaps 15 are closed as follows.

First, the hook plate 22 of the hook member 2 is inserted into the slit portion 152 from the inside to the outside.

At this time, in the box body 1, the length La of the opening base 15a is smaller than the length L2a of the hook plate 22, and the distance Lb between the left and right ends of the notch 15c is the same as or slightly larger than the length L2a. .
Further, the width Db of the gap between the projecting portions 15b and 15b is made larger than the thickness D2b of the connecting portion 23 of the hook member 2 and smaller than the thickness D2a of the hook plate 22.

With the above-described configuration, when the hook plate 22 is passed through the slit portion 152, the overhanging portions 15b, 15b deform to allow the hook plate 22 to pass through, and as the insertion progresses, a connection having a thickness smaller than that of the hook plate 22 is formed. 23. The substrate portion 21 cannot pass through the slit portion 152 because the width D2c is sufficiently larger than the width Da of the opening base portion 15a of the slit portion 152.
This state is shown in FIG. FIG. 5 is a cross-sectional view taken along the line S5-S5 in FIG.

As shown in FIG. 5, the hook plate 22 is held by the protruding parts 15b, 15b of the slit part 152 entering and engaging the connecting part 23, which is thinner than the hook plate 22, from the front and rear directions. Ru. That is, the downward movement of the hook member 2 is restricted by the overhanging portions 15b, 15b being caught on the hook plate 22. Further, the upward movement of the hook member 2 is restricted by the upper surface of the base plate portion 21 coming into contact with the lower surface of the upper and outer flaps 15 .
Thereby, the packaging box 91 prevents the hook member 2 from being pushed into the inside of the box 1 or falling when the box 1 is empty or contains few items.

Further, since the length L2a of the hook plate 22 is longer than the length La of the opening base 15a of the slit portion 152, when the hook plate 22 is passed through the slit portion 152, the left and right side portions of the hook plate 22 are attached to the hook flap 15d. be forcibly lifted.
Thereby, the hook flap 15d is urged to sandwich the end surface 22d of the hook plate 22 in the left-right direction, which is the longitudinal direction, by the repulsive force of the forcibly lifted up force.
This state is shown in FIG. FIG. 6 is a longitudinal sectional view taken along the line S6-S6 in FIG.

As shown in FIG. 6, the hook member 2 is biased so that the left and right end surfaces 22d of the hook plate 22 are sandwiched between the hook flaps 15d, 15d, so that the hook member 2 does not move in the left-right direction with respect to the slit portion 152. Stably positioned.
This prevents the hook member 2 from shifting in the left-right direction with respect to the box body 1.

Moreover, the packaging box 91 is located at a position where the projecting portions 15b, 15b of the box body 1 are close to the connecting portion 23 of the hook member 2 in the front-rear direction. Therefore, the movement of the hook member 2 in the front-rear direction is well regulated by the projecting portions 15b, 15b.
As a result, the movement of the hook member 2 in both left and right and front and back directions with respect to the box body 1 is restricted by the hook flap 15d and the overhanging portion 15b, respectively.
That is, the packaging box 91 having the hook member 2 does not have any usability problems such as the hook member being pushed into the inside of the box body 1 or falling. Moreover, the packaging box 91 does not have the problem of the hook member 2 shifting or shaking with respect to the box body 1. Therefore, it becomes a high quality packaging box.

The embodiment described in detail above is not limited to the above-described configuration, and may be modified without departing from the gist of the present invention.

The packaging box 91 is not limited to having both the hook flap 15d and the overhang portion 15b described above. Regardless of the presence or absence of the connecting portion 23 in the hook member 2, only the hook flap 15d may be provided. In this case, the packaging box 91 is more convenient to use because the hook member 2 does not shift or wobble with respect to the box body 1.
Further, in the case where the hook member 2 has the connecting portion 23, the packaging box 91 may have only the projecting portion 15b. In this case, the packaging box 91 is more convenient to use because the hook member 2 is not pushed into the box 1 or falls.

The distance Lb between the left and right ends of the notch 15c in the slit portion 152 may be smaller than the length L2a of the hook plate 22. In this case, when the hook plate 22 is inserted into the opening base 15a, the hook flap 15d is first raised by both longitudinal ends of the hook plate 22. When the hook plate 22 is further inserted, the notch 15c is cut by the hook plate 22 to a position where the depth of the cut corresponds to the length L2a of the hook plate 22. Therefore, the urging force that pinches the hook plate 22 from the left and right directions is applied not only from the hook flap 15d but also from the upper and outer flaps 15. Thereby, the hook member 2 can be positioned more reliably.

The slit portion 152 is not limited to the one formed in the upper and outer flaps 15. It is sufficient if it is formed on any one of the plurality of flat plate parts HB.
The formation position of the slit portion 152 may be appropriately modified depending on the type of the box 1. For example, if at least one of the right inner flap 12a and the left inner flap 14a is long enough to extend to the center of the upper outer flap 15, a similar slit is formed in the inner flap at a position corresponding to the slit portion 152. A section may be provided.

The hook flap 15d may be formed only on either the left or right side.

The material of the box body 1 is not limited. The box body 1 is made of a bendable material such as coated cardboard, corrugated paper, or resin sheet.
The box body 1 does not have to be of type B.
