Description

  The present invention relates to a corrugated cardboard carton for storing beverage containers and the like.

  As shown in FIG. 3, as a corrugated carton for packaging and storing a beverage container C in a wrap round case, an inner flap 3 is provided from the edge of a pair of side plates 1, and an outer flap 4 is provided from the edge of another pair of side plates 2. Each is used to extend and close the end face by bonding the inner flap 3 and the outer flap 4 together.

  When taking out the wrap round case M from such a carton, the cut tape 5 on the side may be cut, but a finger is put into the abutting portion of the outer flap 4 and the outer flap 4 is peeled off from the inner flap 3. In many cases, the end surface of the carton is opened, and the wrap round case M is taken out from the opening. It is considered that the majority of the cases where the individual purchases in case units, unpack the contents by unwrapping the hands from the wife side to the end of the wife flap.

  At this time, there is a problem that it is easy to cut the hand at the edge of the outer flap 4, so in the conventional carton, a waveform having a pitch of about 2 mm is formed on the outer periphery, and the hand does not come into linear contact with the edge of the outer flap 4. I am doing so.

  As a corrugated cardboard carton that makes it difficult to cut hands, Patent Document 1 discloses that an inner flap is extended from the edge of a pair of side plates, an outer flap is extended from the edge of another pair of side plates, and the inner flap and the outer flap are bonded together. A corrugated cardboard carton that closes the end face and softens the hand by squeezing the edge of the outer flap by crushing or crease lines, etc., and also forms irregularities on the edge of the outer flap to prevent hand slipping A carton has been proposed.

  However, with these means, the rigidity of the corrugated cardboard sheet can be reduced, but the rigidity of the paper (liner) itself is small, and the rigidity of the paper itself is greatly increased so that it may actually be cut by thin paper even in daily life. It is difficult to significantly reduce the risk of injury if it is not reduced.

  However, even if such countermeasures are taken, the hand may be cut unexpectedly, so it is an issue to provide a corrugated cardboard carton that makes it difficult to cut the hand by greatly reducing the rigidity of the paper edge itself. is there.

The invention according to claim 1 of the present invention for solving the above-described problems is that the inner flap extends from the end edges of the pair of side plates and the outer flap extends from the end edges of the other pair of side plates, respectively. In a corrugated carton that closes the end face by pasting together, forming a crushing portion having a plurality of cuts facing the end edge at a location that does not overlap the inner flap of the outer flap ,
The cardboard carton is characterized in that the plurality of cuts are arranged in a comb shape on the edge of the outer flap, the cut interval is 5 to 15 mm, and the cut depth is 5 to 10 mm .

  As described above, in the corrugated cardboard carton according to the present invention, the end portion of the outer flap is crushed by forming the crushed portion having a plurality of cuts facing the end edge on the outer flap that is put on the hand at the time of opening. The cardboard carton can be made harder when it is opened by reducing the rigidity of the edge of the paper (liner) and softening the hand compared to the case of only the case where only a ruled line or the like is inserted. .

  In other words, the effect of reducing the resistance due to the rigidity of the finger contact can be exhibited by making the paper edge at the time of finger contact easy to bend by making the cut and simultaneously crushing the entire thickness of the cardboard end part.

In addition, by in inventions cardboard carton of the present invention, the plurality of cuts are arranged in a comb shape on the outer flap edge, the interval of the cut is 5 to 15 mm, the depth of cut is 5 to 10 mm, the finger The contact with the can effectively be performed and the safety at the time of opening can be further enhanced.

It is the schematic which shows the blanks of an example of the corrugated cardboard carton of this invention. It is the schematic which shows an example of the outer flap edge of the cardboard carton of this invention. It is the schematic which shows an example of a cardboard carton.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The overall structure of the cardboard carton of the present invention is the same as that shown in FIG. Here, FIG. 1 will be used to explain the position of the cut processing portion, which is a feature of the present invention, and the shape of the cut processing portion in FIG.

  The corrugated cardboard carton of the present invention is produced, for example, by assembling the blanks shown in FIG. 1 into the shape shown in FIG.

  That is, the inner flap (3) is extended from the end edges of the pair of side plates (1), and the outer flap (4) is extended from the end edges of the other pair of side plates (2), so that the inner flap (3) and the outer flap (4 ) And the end face is closed to form a crushed portion having a plurality of cuts at the edge (8) of the outer flap (4).

  One of the normally envisaged opening methods is to cut the perimeter along the cut tape (5) from the cut portion of the opening cut (7), but with the finger on the end of the outer flap (4) It is often opened by pulling from the wife.

  At that time, since the finger is placed at the position of the cut portion (8) at the end portion of the outer flap displayed in FIG. 1, the finger is likely to be cut in the normal end processing. Therefore, in the corrugated carton of the present invention, not only the notch (10) as shown in FIG. 2 is enlarged, but also the notched portion (8) is compressed in the thickness direction to greatly increase the rigidity of the paper edge. This reduces the possibility of injury to the finger.

The interval between cuts (A) is suitably in the range of 5 mm to 15 mm in relation to the thickness of the finger, and the depth of cut (B) is in the range of 5 mm to 10 mm due to the relationship with the fingertip length. It is.

  As a matter of course, this cutting process can be provided not only in the illustrated outer flap portion but also in other portions as necessary, thereby providing a more effective cardboard carton for preventing hand injury.

  In this way, according to the corrugated cardboard carton of the present invention, a cardboard carton that is less likely to be cut unexpectedly and hard to cut when opening is obtained by greatly reducing the rigidity of the paper edge itself of the cardboard. I was able to do it.
