Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carton used for packaging beverage cans and the like.

[0002]

2. Description of the Related Art Generally, when packaging beer cans and the like,
As shown in FIG. 6, each pair of the wide plate 50 and the narrow plate 51
And an inner flap 52 extending from an edge of the narrow face plate 51.
And an outer flap 53 extending from the edge of the wide panel 50, and a wrap round type carton made of corrugated cardboard for closing the end face is used.

The carton is provided with a tear band 54 extending from the narrow plate 51 to the inner flap 52 and between the outer flaps 53 by a liner cut or the like. It is formed from the center toward both ends.

[0004]

However, in such a carton, when opening, the tear band 54 is attached to each narrow face plate 51.
Must be divided into four operations from the cut-out portion 55, which is troublesome.

Therefore, an object of the present invention is to provide a carton that can be opened easily and easily.

[0006]

In order to solve the above-mentioned problems, the present invention provides a structure in which a pair of wide surface plates and a pair of narrow surface plates are connected to each other,
An inner flap extending from the edge of the narrow plate and an outer flap extending from the edge of the wide plate are attached to each other, and a tear band is provided from the narrow plate to the inner flap and extends between the outer flaps. The cutout of the band was located at the ridge of the narrow face plate and the inner flap.

If a cutout is provided at such a position, the tear band can be opened simply by cutting in a direction from the cutout.

Further, if a push-in portion is provided on the inner flap adjacent to the cut-out portion, the cut-out portion can be easily gripped, and a cut is provided from the portion adjacent to the cut-out portion to the edge of the inner flap. The inner flap is cut by the weight of the stored item.

[0009]

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

As shown in FIG. 1, in the corrugated cardboard blank of this carton, a pair of wide surface plates 1 and narrow surface plates 2 are alternately provided in a row. The outer flaps 4 are respectively connected to the edges of the outer flaps. On the outer edge of one of the narrow face plates 2, a passage piece 5 is provided.

Further, a tear band 6 is provided from the narrow plate 2 to the inner flap 3 by sticking a cut tape or liner cut. It is located in.

The leading end of the cutout 7 is slightly displaced toward the inner flap 3 from the ridge line of the narrow face plate 2 and the inner flap 3. 4 has a notch 9 corresponding to the push-in portion 8.
A zipper-shaped cut 10 is provided from the pushing portion 8 to the edge of the inner flap 3.

In order to assemble a carton from such a blank and package a beverage can, as shown in FIG. 2, each pair of the wide surface plate 1 and the narrow surface plate 2 is bent into a rectangular tube shape, and The inner flap 3 and the outer flap 4 are sequentially bent inward and bonded to the inner surface of the opposite wide panel 1.

In the carton thus assembled, FIG.
As shown in FIG. 7, the leading end of the cut-out portion 7 protrudes from the ridge line of the narrow face plate 2 and the inner flap 3 and the push-in portion 8 is exposed from the cut-out portion 9 of the outer flap 4. Can be found.

Then, as shown in FIG. 4, the push-in portion 8 is pushed inward by using a gap between the can and the carton, and the cut-out portion 7 is formed.
And tearing the tear band 6 in one direction, the outer periphery of the carton is cut except for the two inner flaps 3 adjacent to the cutout 7.

Then, when the upper part of the carton is pulled up,
As shown in FIG. 5, the weight of the can C packaged with the multi-pack M acts on the lower part of the tray-shaped carton, and the uncut inner flap 3 breaks along the cut 10,
The top of the carton can be removed.

[0017]

As described above, in the carton according to the present invention, the cutout portion of the tear band is located at the ridge portion of the narrow face plate and the inner flap, and the push portion is inserted into the inner flap adjacent to the cutout portion. And cuts, so push in the push-in part, pick out the cut-out part,
The tear band can be easily opened simply by cutting it in one direction.
