DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard or other cardboard packaging box for accommodating a large number of beverage cans, such as canned beer and canned juice, arranged vertically and horizontally.

[0002]

2. Description of the Related Art As shown in FIG. 6, a packing box of this type has a top plate 4 above and below a body 1 composed of a pair of opposed side plates 2 and a pair of opposed end plates 3. As shown in FIG. In some cases, a lower surface plate 5 is provided, and a cutout 6 is provided around the body 1 to divide the body 1 into upper and lower parts. FIG. 8 shows a blank in which the packaging box is developed.

[0003] In such a packaging box, when the cutout 6 of the body 1 is cut off, the body 1 is divided into upper and lower parts, and the upper half is removed, as shown in FIG. Can be used as

[0004]

As described above, when the body 1 of the packaging box is divided into upper and lower parts and the lower half is used as a tray, the peripheral wall around the lower surface plate 5 has Since it is constituted by the lower half of the part 1, the height is relatively low over the entire circumference.

Therefore, when the tray is lifted, the strength of the tray is weak against the vertical force, and the tray may be folded in a folded state from a middle portion of the side plate 2 forming the body 1. Was.

Further, since the height of the peripheral wall of the tray is formed low over the entire circumference, there is a problem that it is difficult to grasp the peripheral wall when lifting the tray.

Accordingly, the present invention is directed to a cardboard or other cardboard made of cardboard or the like which is hard to bend into two folds when the lower half is used as a tray and the lower half is used as a tray, and which is easy to grasp the peripheral wall when lifting. The present invention is intended to provide a packaging box.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a cardboard or other cardboard made of a cardboard provided with a cutout for vertically dividing the trunk around the trunk as described above. In a packaging box, a cut line is formed in a central portion of an upper half portion of the side plate forming the body portion so as to be continuous with a lower half portion of the side plate and form a reinforcing wall which rises upward. is there.

The reinforcing wall may have any shape such as a mountain shape, a trapezoid shape, a triangular shape, and the like.

[0010]

According to the above construction, when the trunk is divided into upper and lower parts, the reinforcing wall which rises upward is formed integrally at the center of the lower half of the side plate, so that the divided lower half is formed. When this is used as a tray, the strength against the vertical force is increased, and it is possible to prevent the side plate from being bent from the middle part.

Further, it is possible to have a reinforcing wall which rises above the side plate when lifting.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 to 3 show a first embodiment of a packaging box according to the present invention.

The packaging box comprises a rectangular cylindrical body 11 having a relatively low height, and upper and lower plates 12 and 13 provided above and below the body 11, respectively. Is assembled from a cardboard blank such as a cardboard shown in FIG.

The body 11 includes a pair of opposed side plates 14.
And a pair of end face plates 15 facing each other. End plate 15
Are inner flaps 16 connected to the left and right sides of the side plate 14.
And a pair of upper and lower outer flaps 17 and 18 connected to the left and right sides of the upper plate 12 and the lower plate 13, and the upper and lower outer flaps 17 and 18 are attached to the outer surface of the inner flap 16 and The edges meet each other.

As shown in FIG. 3, the upper plate 12, the lower plate 13 and the pair of side plates 14 are connected to each other via a bending line. The glue allowance piece 19 is continuously provided.

A cutout 20 for dividing the body 11 into upper and lower portions is formed in the side plate 14 and the inner flap 16 forming the body 11. This cutout 20
Is formed by two parallel discontinuous score lines 21, which are formed only on the inner surface side, that is, in the case of corrugated cardboard, only on the inner liner paper so as not to penetrate the outer surface side. I have.

The side plate 14 is provided with the cutout portion 20.
When cutting is performed, a pair of knob portions 22 for guiding the cut portion toward the cut line 21 of the cut portion 20 are formed at predetermined intervals on the left and right. This knob 22
Is a vertical cut 23 crossing the cut line 21 in the vertical direction;
The vertical cut 23 is formed outwardly from both upper and lower end portions by a pair of upper and lower transverse cuts 24 whose outer intervals are slightly narrower.

At the center of the upper half of the side plate 14,
A score line 26 that forms the mountain-shaped reinforcing wall 25 is formed starting from the left and right knobs 22 and the left and right knobs 2.
2, each of the cutout portions 20 is cut out toward the outside, and the cut line 26 is cut off. As shown in FIG. 2, the mountain-shaped reinforcing wall 25 is integrated with the central portion of the lower half of the side plate 14. And remain in an upright state.

The chevron-shaped reinforcing wall 25 is formed so that its height almost reaches the upper side of the side plate 14.

Above the left and right knobs 22, a vertical cut 27 is formed so as to be orthogonal to the upper transverse cut 24 of the pair of upper and lower transverse cuts 24. The vertical cut 27 and the reinforcing wall 25 are formed. A push-in piece 28 is formed between the lower end portion of the cut line 26 to be formed, and when the knob 22 is grasped,
By pushing the pushing piece 28 inward, the knob 22 can be easily grasped. That is, the pushing piece 28
If there is not, when grasping the knob part 22, the knob part 22
Must be pushed inward, and then the knob portion 22 must be pulled out, so that the cutting operation of the cutting portion 20 cannot be performed in one operation.

In the bent portion on the upper side of the side plate 14, when the packaging box is assembled, the upper side is bent so that the score line 26 of the reinforcing wall 25 near the upper side is not turned up by bending the upper side. A cut 29 is provided.

In addition, auxiliary cut lines 30 are formed on both sides of the side plate 14 and the inner flap 16 above and below the cut portion 20 in order to facilitate the cut of the corner portion by the cut portion 20. .

At one corner of the top plate 12, a cut line 31 for forming an outlet for forming an outlet for taking out the internal beverage can with the end plate 15 standing down is provided. Is provided.

Next, FIGS. 4 and 5 show a second embodiment of the packaging box according to the present invention.

This packaging box is for accommodating a beverage can that is taller than the packaging box of the first embodiment, and the height of the body 11 is equal to that of the packaging box of the first embodiment. Higher.

For this reason, the height of the chevron-shaped reinforcing wall 25 is formed slightly lower than the height of the side plate 14, and a reinforcement is provided between the top of the chevron-shaped reinforcing wall 25 and the upper side of the side plate 14. When cutting the score line 26 forming the wall 25, a cut 32 is provided to facilitate the cut.

In the second embodiment, portions corresponding to those in the first embodiment are denoted by the same reference numerals.

[0029]

As described above, in the packaging box of the present invention, when the body is divided into upper and lower parts and the lower half is used as a tray, it rises upward at the center of the side plate. Since the reinforcing wall is formed, it has high strength against a vertical force when lifted, and can prevent the side plate from being bent.

Further, the provision of the reinforcing plate which rises upward has the effect of being easy to lift.

Further, since the side plate has a reinforcing plate which rises upward, by printing an advertisement or the like on this portion, an excellent advertisement effect can be obtained even in the case of a tray shape.

Further, by forming the pushing piece above the knob, there is also an effect that the cutting operation of the cutting section can be performed in one behavior.
