Abstract

PROBLEM TO BE SOLVED: To provide a corrugated fiberboard carton with which a cut is difficult to get on a hand when unsealing. SOLUTION: The corrugated fiberboard carton comprises inner flaps 3 extending from end rims of one of pairs of side plates 1 and outer flaps 4 extending from end rims of the other pair of side plates 2, wherein the inner flaps 3 and the outer flaps 4 are glued to close end faces. End rims of the outer flaps 4 are made fragile by a crush, rules or the like to be soft for a hand. In addition, an uneven portion is formed at the end rim of the outer flap 4 to prevent hands from slipping.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard carton for storing beverage containers and the like.

[0002]

2. Description of the Related Art As shown in FIG. 9, as a cardboard carton for packaging and storing a beverage container C in a multi-pack M,
The inner flap 3 is moved from the edge of the pair of side plates 1 to the other pair of side plates 2.
Are used to extend the outer flaps 4 from the end edges thereof and bond the inner flaps 3 and the outer flaps 4 to close the end faces.

[0003] When taking out the multi-pack M from such a carton, the separating band 5 on the side surface may be cut.
Put a finger into the abutting portion of the outer flap 4, peel the outer flap 4 from the inner flap 3 to open the end face of the carton,
The multipack M is often taken out from the opening.

At this time, since there is a problem that the hand is easily cut at the edge of the outer flap 4, in the conventional carton, a waveform having a pitch of about 2 mm is formed on the outer periphery, and the hand is straightened on the edge of the outer flap 4. Avoid contact with

[0005]

However, even if such measures are taken, the hand may be suddenly cut off. Therefore, there is a demand for a cardboard carton which is more difficult to cut.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention forms an outer flap with a crushed portion facing an edge of the outer flap. It is intended to be soft.

The outer flap is provided with a ruled line parallel to the leading edge thereof, so that the outer flap breaks at the time of opening, so that the hand can be softened.

The outer flap is provided with a perforation close to its edge, and the perforation weakens the edge of the outer flap so that the hand can be softened.

Further, a minute waveform having a pitch of about 1 mm is formed at the edge of the outer flap, and the paper layer is weakened by impact at the time of punching.
The edge of the outer flap is easily collapsed when opened.

In addition, the edge of the outer flap has a period of 20 m.
The wavy edges are approximately wavy at a length of about m to 40 mm to prevent hand slippage.

In addition, circular cuts are arranged at intervals on the edge of the outer flap to prevent hand slippage.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the overall structure of the carton according to each embodiment is the same as that shown in FIG. 9, and therefore, only the features thereof will be described here.

In the first embodiment shown in FIG. 1, a crushed portion 5 is formed by crushing the edge of the outer flap 4 from the front liner side. In this carton, the edge of the outer flap 4 is inclined inward, and the hand at the time of opening is soft, so that the hand is hard to cut.

In the second embodiment shown in FIG. 2, the outer flap 4 is provided with a ruled line 6 parallel to the leading edge. In this carton, the outer flap 4 is easily broken along the ruled line 6 at the time of opening, so that the touch of the hand becomes soft,
Hands are hard to cut.

In the third embodiment shown in FIG. 3, the outer flap 4 is provided with a perforation 7 close to its edge.
In this carton, the liner of the outer flap 4 is torn along the perforations 7 and its edge is weakened, so that the hand is soft and the hand is hard to cut.

In the fourth embodiment shown in FIG. 4, a minute waveform 8 having a pitch of about 1 mm is formed at the edge of the outer flap 4. In this carton, the paper layer is weakened by impact at the time of punching, so that when the hand is applied at the time of opening, the edge of the outer flap 4 is easily crushed and the hand is hard to cut.

In the fifth embodiment shown in FIG. 5, the edge of the outer flap 4 is a wavy edge 9 having a period of 20 mm. In the sixth embodiment shown in FIG. 6, the edge of the outer flap 4 is a wavy edge 9 having a period of 40 mm. In these cartons, the wavy edges 9 prevent slipping of the hand and make it difficult to cut the hand.

In the seventh embodiment shown in FIG. 7, arc cuts 10 are arranged at an edge of the outer flap 4 at intervals of 30 mm. In the eighth embodiment shown in FIG. 8, an arc cut 10 is formed at an edge of the outer flap 4 at a distance of 20 mm.
Is arranged. Even in these cartons, the arc cut 1
A value of 0 prevents hand slippage and makes it difficult to cut the hand.

In each of the embodiments except the fourth embodiment, when a waveform of about 2 mm pitch similar to the conventional one or a waveform of about 1 mm pitch as in the fourth embodiment is formed on the outer periphery of the carton, Since the hand comes into contact with the edge intermittently, the hand can be more effectively prevented from being cut.

[0020]

As described above, in the corrugated cardboard carton according to the present invention, the edge of the outer flap is softened by crushing or weakening the edge with a ruled line or the like. Since it formed to prevent slipping of the hand, it was difficult to cut the hand when opening.
