In the blank, as shown in FIG. 1, a pair of wide surface plates 2 and narrow surface plates 3 forming a cylindrical body 1 are connected alternately, and a passage piece 4 extends from the outer edge of one of the wide surface plates 2. End plates 5 are respectively provided at both end edges of the wide surface plate 2 and the narrow surface plate 3.

A reinforcing tape 6 is adhered to the portion of the tubular body 1 so as to cross the central portion, and the step of the corrugated cardboard faces in a direction orthogonal to the reinforcing tape 6.

A narrow plate 3 sandwiched between a pair of wide plates 2 has
A cut 7 is engraved on one side in parallel with the reinforcing tape 6, and both ends of the cut 7 are cut into the wide surface plate 2 and are inclined obliquely so as to approach the reinforcing tape 6. A fold 8 is provided between both ends of the cut 7, and a press piece 9 is formed between the cut 7 and the fold 8.

A notch 10 is formed in the ridge of the narrow plate 3 and the wide plate 2 on the opposite side of the cut 7 with the reinforcing tape 6 therebetween.
Is provided.

In order to package the can C with such a blank, as shown in FIG. 2, each pair of the wide surface plate 2 and the narrow surface plate 3 is bent so as to wrap the can C, and the passage piece 4 is placed on the opposite side. The tubular body 1 is formed by sticking to the narrow face plate 3, and the end plate 5 is bent inward so as to close the end face, and is attached.

In this state, when one of the wide plates 2 is placed on top of the other and flat stacked, the step of the narrow plate 3 faces in the horizontal direction, but the load of the upper case is received by the can C. Is not crushed, and the deformation of the narrow face plate 3 is absorbed by the movement of the ridge line between the wide face plate 2 and the narrow face plate 3, and the narrow face plate 3
Bulging is prevented.

And when carrying this carton,
As shown in FIGS. 3 and 4, with the narrow face plate 3 having the cuts 7 facing upward, the pushing pieces 9 are pushed in using the depressions between the peripheral walls of the adjacent cans C.

As a result, the handle hole 1
1 is formed, and the pushing piece 9 overlaps the narrow face plate 3 so that the handle portion 1 is formed.
2 is formed, a hand is put into the handle hole 11 and the handle portion 1 is formed.
2 can be carried as if lifted.

At this time, the corrugated direction of the corrugated cardboard and the cut 1
By the action of 0, the handle portion 12 bends relatively largely upward while the both side portions fall inward, so that the hand can be easily put into the handle hole 11.

Further, since the handle 12 is reinforced by the reinforcing tape 6 extending around the entire circumference of the tubular body 1, it is difficult for the handle 12 to crack when it is carried. Can be carried without dropping.

Also, in this carton, since the direction of the corrugated cardboard and the direction of the reinforcing tape 6 are orthogonal to each other, the reinforcing tape 6 is fed out in the paper feeding direction during the production of the corrugated cardboard.
It can be attached efficiently.

Here, the reinforcing tape 6 may be adhered to the back surface of the corrugated cardboard. However, as shown in FIG. The reinforcing tape 6 may be inserted between the shins 14. In this case, the reinforcing effect of the corrugated cardboard by the reinforcing tape 6 is enhanced, and there is no disadvantage in printing.

As the reinforcing tape 6, if an ester string or a cotton flat tape coated with a hot melt adhesive is used, sufficient strength and adhesiveness can be obtained. In particular,
In the case of a cotton tape, it is possible to use the starch paste for attaching the liner 13 and the middle shin 14 during the production of the corrugated cardboard, and to bond them as they are.

Next, a second embodiment of the present invention will be described with reference to FIGS.
