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

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

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

The body 11 has a pair of side plates 14 facing each other.
And a pair of end plates 15 facing each other. End plate 15
Is an inner flap 16 that is continuously provided on 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 pair of upper and lower outer flaps 17 and 18 are attached to the outer surface of the inner flap 16 and have a tip. The edges are designed to abut 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, and one side plate 14 and a side of the upper plate 12 are connected to each other. The glue pieces 19 to be laminated are arranged in series.

The side plate 14 and the inner flap 16 forming the body 11 are formed with a cutout 20 for dividing the body 11 into upper and lower parts. This cutout 20
Is formed by two parallel discontinuous cut 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 to the outer surface side. There is.

The side plate 14 has the cutout portion 20.
A pair of knob portions 22 that guide the cutout portion toward the cut line 21 of the cutout portion 20 are formed on the left and right at predetermined intervals when the cutout is cut. This knob 22
Is a vertical cut 23 that crosses the cut line 21 in the vertical direction,
The vertical cut 23 is formed by a pair of upper and lower horizontal cuts 24 that are formed outward from both upper and lower end portions and have a slightly narrower outer space.

In the central portion of the upper half of the side plate 14,
A cut line 26 that forms a mountain-shaped reinforcing wall 25 is formed starting from the left and right knob portions 22, and the left and right knob portions 2 are formed.
2 and cut the cutouts 20 outward, respectively, and further cut out the cut lines 26, and as shown in FIG. 2, the chevron-shaped reinforcing wall 25 is integrated with the central portion of the lower half of the side plate 14. It is connected to and remains upright.

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

A vertical cut 27 is formed above the left and right knobs 22 so as to be orthogonal to the upper horizontal cut 24 of the pair of upper and lower horizontal 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 gripping the knob portion 22,
By pushing the pushing piece 28 inward, the knob portion 22 is easily grasped. That is, the pushing piece 28
Without it, when grasping the knob portion 22, the knob portion 22
Has to be pushed inward, and then the knob portion 22 must be pulled out to the outside, so that the cutting operation of the cutout portion 20 cannot be performed in one movement.

When assembling the packaging box, the bent portion of the upper side of the side plate 14 is arranged along the upper side so that the cut line 26 portion of the reinforcing wall 25 near the upper side does not turn up when the upper side is folded. A cut 29 is provided.

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

Further, at one corner portion of the upper plate 12, a cut line 31 for forming a take-out port for forming a take-out port for taking out an internal beverage can is provided with the end face plate 15 standing down. It 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 portion 11 is the packaging box of the first embodiment. Is formed higher than.

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 line 32 is provided for facilitating the cut.

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

[0029]

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

Also, by having a reinforcing plate that rises upward, there is an effect that it is easy to lift.

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

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