Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a corrugated cardboard wrap round case for collecting and packaging a plurality of cans .
[0002]
[Prior art]
For example, for packaging of canned beer, as shown in FIG. 7, each pair of elevation plates 51 and flat plates 52 is bent so as to enclose can C, and a passage 53 is attached to form a peripheral wall. A cardboard wrap round case is used in which the flaps 54 and 55 extending from the face plate 51 and the flat plate 52 are closed to close the end faces.
[0003]
[Problems to be solved by the invention]
By the way, if a large number of wrap round cases as described above are stacked and stored, the upright plate 51 swells due to the phenomenon that the can bites into the corrugated cardboard of the flat plate 52 due to the accumulated load, and the aesthetic appearance is impaired. is there.
[0004]
As a countermeasure, two ruled lines that are parallel to the entire length of the ridges of the upright plate 51 and the flat plate 52 may be placed, and one of them may be used as a buckling induction line. The ruled lines that are bent at the time of box making are not constant, and there is a risk of poor box making.
[0005]
Therefore, the present invention is intended to provide a corrugated cardboard wrap round case that is less likely to bulge due to a loading load, maintains its aesthetic appearance, and has excellent boxing suitability with a caser.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a corrugated cardboard wrap round in which a pair of elevation plates and a plane plate are bent to form a peripheral wall so as to enclose a plurality of integrated cans, and a flap is closed to close an end surface. In the case, a plurality of one ruled line and two parallel ruled lines shifted from each other are alternately arranged at the boundary portion between the elevation plate and the plane plate so as to correspond to the can with a cut. However, without providing a ruled line between the two parallel ruled lines, the part between the two parallel ruled lines is placed on the outer periphery of the end of the can with the folding along the ruled line of the elevation plate and the plane plate. It was made to become diagonal along .
[0007]
In such a wrap round case, when the loading load is applied, the bending angle of the two parallel ruled lines changes and the deformation in the height direction is absorbed, so that the swelling of the trunk is suppressed.
[0008]
In addition, when folding the ridges of the vertical plate and flat plate during box making, two parallel ruled lines are evenly folded following one ruled line, so that one side of the ruled line does not break, making the box making The occurrence of defects is prevented.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0010]
This corrugated cardboard wrap round case, as shown in FIG. 1 and FIG. 2, bends each pair of elevation plates 1 and plane plates 2 so as to enclose can C, and attaches passage 3 to form a peripheral wall, The flaps 4 and 5 are closed to close the end face. The standing plate 1 and the flap 4 are provided with a tear strip 6 for half-cut opening.
[0011]
In the blank of this wrap round case, as shown in FIG. 3, the ridge portion between one flat plate 2 and the elevation plate 1 on both sides thereof is shifted with respect to one ruled line 7 located in the center . Two parallel ruled lines 8 are alternately arranged with a cut. Further, the height of the elevation plate 1 having the ruled line 7 as the lower end is smaller than the height of the can C.
[0012]
When assembling the blank and wrapping the can C, as shown in FIG. 4, when the elevation plate 1 is folded from the flat plate 2, first, a single ruled line 7 starts to be broken, and two pieces are accompanied by this. The ruled lines 8 start to be broken evenly.
[0013]
Then, as shown in FIG. 5, when the upright plate 1 stands up, the portion between the two ruled lines 8 bends diagonally, the peripheral portion of the one ruled line 7 is tightened, and the can C is tightly packaged. The
[0014]
When packaged in this way, even when the upper and lower flanges of the can C bite into the corrugated cardboard of the flat plate 2 when a loading load is applied, the bending angle of the ruled line 8 changes and the deformation in the height direction is absorbed. Therefore, the elevation board 1 is hard to swell.
[0015]
Moreover, since one ruled line 8 does not break at the time of box making, even if it is packed with a high-speed caser, troubles of box making failure do not occur.
[0016]
Furthermore, since the area of the blank can be made smaller than that of the conventional one and the can C is directly subjected to a loading load, low-grade corrugated cardboard can be used as the material, so that packaging costs can be reduced.
[0017]
In this embodiment, the ruled lines 7 and 8 are provided on the ridges of the lower flat plate 2 and the both side elevation plates 1, but instead of or in addition to this, the upper plane plate 2 and the both side elevation plates. The ruled lines 7 and 8 may be provided on one ridge.
[0018]
In addition, as shown in FIG. 6, when the tear strip 6 is bent upwardly in an arch shape, the elevation plate 1 is less likely to buckle at the tear strip 6, and even if the tray-shaped portion is opened and carried, the elevation plate The center part of 1 becomes difficult to bend in the vertical direction.
[0019]
【The invention's effect】
As described above, in the wrap round case according to the present invention, when the loading load is applied, the bending angle of the two parallel ruled lines changes to absorb the deformation in the height direction, so that the swelling of the body is suppressed. At the time of box making, since one ruled line portion prevents the two ruled lines from being broken, the box making defect can be prevented.
