Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper box with a handle for folding and assembling a blank.
[0002]
[Prior art]
Conventionally, beverages such as sake, for example, are sometimes sold by packing three relatively small bottles into a paper box with a handle. In this case, as the paper box with a handle, a paper box that is horizontally long so that three bottles can be stored side by side, or a container that can store bottles in a triangular shape with a horizontal cross section substantially triangular can be used. .
[0003]
However, the horizontally long box has a problem in that it is easy to collapse when placed and its stability is poor. In addition, since the box with a roughly triangular cross section is irregular, it is difficult to make an automatic box (the process from assembling the bottom of the box to the bottom of the box with a mechanical device), and it is also a cardboard box for shipping at the time of shipment. It is difficult to pack tightly.
[0004]
On the other hand, these problems will not occur if a rectangular box with a horizontal cross section of approximately square or wide is used, but when the bottle is divided into four by the vertical and horizontal center lines, Since the center of gravity of the three bottles is deviated from the center of the box, the balance becomes poor and it may be difficult to hold.
[0005]
[Problems to be solved by the invention]
Therefore, the technical problem to be solved by the present invention is to provide a rectangular box that can improve the balance when holding three bottles or the like. It is good to make automatic box making and suitable for packing at the time of shipment.
[0006]
The paper box with a handle according to the present invention is a paper box with a handle formed by bending a blank, and is connected to a rectangular bottom wall and four sides of the bottom wall. And four side walls that are continuous in the circumferential direction, a lid plate that is foldably connected to the upper side of the two side walls, a handle piece that is foldably connected to the lid plate, and other parts that engage with the handle piece. In order to solve the above technical problem, a corner portion of the first pair of adjacent side walls and the cover plate is formed on a diagonal line on the cover plate passing through the corner. The handle holding piece is chamfered by an inclined surface that passes through a continuous line between the end points of the upper side that is substantially perpendicular and bisects the upper side of each of the first pair of adjacent side walls. It is connected to the upper side so that it can be bent, In addition, the cover plate is formed to be foldably connected to the upper sides of the second pair of adjacent side walls, and the handle piece has a convex portion protruding from the side end to the handle holding piece side, and the handle The holding piece includes a slit into which the convex portion can be inserted, and a notch connected to the slit. The notch is a convex portion of the handle piece when the handle piece and the handle holding piece are folded toward the cover plate. Is formed in an arc shape so as to be movable, and the handle piece is connected to each cover plate so as to be foldable on the diagonal line in a state where the box is assembled.
[0007]
In the said structure, since one place of the upper-end corner part of a box is chamfered with the inclined surface, the handle piece formed on the diagonal of the cover plate is located off the center of the box. For this reason, if three bottles are arranged in a box and stored in a triangle, the center of the handle piece is adjusted to 3 by adjusting the size of the chamfer after the bottle is not placed under the chamfer. Since it can be adjusted to the center of gravity of the bottle, the balance when holding the box can be improved. Further, since the box does not have to be horizontally long in order to improve the balance when it is held in this way, the stability of the box can be improved. Furthermore, since this box is rectangular, automatic box making is easy and it is also suitable for packing at the time of shipment.
[0009]
If comprised in this way, a handle piece and a handle holding piece can be folded to the cover-plate side, moving the convex part of a handle piece along the notch | incision of a handle holding piece. Therefore, since the cover plate becomes substantially flat with the handle piece and the handle holding piece folded, the boxes can be stacked and displayed at a store or the like.
[0010]
In the above configuration, the bottom wall is composed of four bottom wall constituent pieces connected to the lower side of each side wall so as to be bendable, and the bottom wall constituent pieces are adjacent to each other across one diagonal of the box. Partitions connected to each other so that they can be folded along a diagonal passing through the diagonal, and connected to each bottom wall component piece so as to be foldable to the bottom wall component piece at sides parallel to the four sides of the bottom wall. In addition, the partition pieces formed on the pair of bottom wall constituent pieces connected to each other are connected to each other so that they can be bent along a side parallel to the side of the side wall, and between the bottom wall constituent piece and the partition piece. It is preferable that the formed locking portion is held by engagement between the locking portions in a state where the bottom wall is formed.
[0011]
With this configuration, when the box is folded, the bottom wall component piece and the partition piece are folded along the side wall, but the lower side of the partition piece is parallel to the four sides of the bottom wall and the side piece is parallel to the side of the side wall. Therefore, the partition piece rises from the bottom wall and the bottom wall is formed and fixed as the bottom wall constituting pieces are combined when the box is assembled. At this time, the inside of the box is divided into four parallel to the four sides of the bottom wall. Accordingly, if the bottles are stored in three places except the position below the inclined surface and the center of the handle is aligned with the center of gravity, the balance when holding the box can be improved.
[0012]
