This application is based upon and claims the benefit of priority from the corresponding Japanese Patent Application No. 2018-216136 filed on Nov. 19, 2018, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a partition built by bending one sheet, and also relates to a packing material using such a partition.
As a conventionally common method for packing electronic appliances and the like, what is called assembled packing is widely used in which partitions are arranged in cardboard boxes to pack a plurality of parts together.
For example, according to a known method for packing a motor, two kinds of strip-like partitions with slits are combined into a lattice and arranged inside an outer cardboard box to store the motor in the lattice. There is also a known plastic cardboard box in which opposite sides have a double wall structure and the inner side of the double wall integrally connected at the top with the inner wall located on the outside of the double wall has a plurality of perpendicular partition grooves so that partition segments can be inserted in appropriate grooves according to the dimensions of an industrial component.
According to one aspect of the present disclosure, a partition includes a bottom plate, a pair of first partition segments, a first folding line, a second folding line, a pair of first slits, a pair of second partition segments, a third folding line, and a fourth folding line, second slits, and the partition is built using one sheet material. The bottom plate is in a rectangular shape having a pair of first sides opposite from each other and a pair of second sides perpendicular to the first side. The pair of first partition segments is arranged along the pair of first sides. The first folding line extends from each of a pair of first vertexes of the bottom plate located on one diagonal position each other to an end point located on each of the pair of first sides and which connects the bottom plate and each of the pair of first partition segments together. The second folding line extends perpendicularly to the first folding line from end point of the first folding line to an outer edge of the first partition segment. The pair of first slits is slit from the outer edge of each of the pair of first partition segments inward. A pair of second partition segments is arranged along the pair of second sides. The third folding line extends from each of a pair of second vertexes of the bottom plate located on another diagonal position each other to an end point on each of the pair of second sides and which connects the bottom plate and each of the pair of second partition segments together. The fourth folding line extends perpendicularly to the third folding line from the end point of the third folding line to an inner edge of the second partition segments. The pair of second slits is slit from the inner edge of each of the pair of second partition segments outward. The pair of first partition segments and the pair of second partition segments are held erect with respect to the bottom plate in an L shape as seen in a plan view by bending each of the pair of first partition segments perpendicularly along the first folding line and the second folding line to make the first partition segments erect in an L shape and to arrange each of the pair of first partition segments on the bottom plate; bending each of the pair of second partition segments perpendicularly along the third folding line and the fourth folding line to make the second partition segments erect in an L shape and to arrange each of the pair of second partition segments on the bottom plate perpendicularly to the pair of first partition segments; and making the pair of second slits engage with the pair of first slits each other.
This and other objects of the present disclosure, and the specific benefits obtained according to the present disclosure, will become apparent from the description of embodiments which follows.
Hereinafter, with reference to the accompanying drawings, embodiments of the present disclosure will be described.
The bottom plate 2 has a rectangular (square) shape. To first sides 2a (the left and right sides in
On the first partition segment 3a or 3b, the second folding line L2 is formed. The second folding line L2 extends from one end (the end point) of the first folding line L1 perpendicularly to the first folding line L1 to an outer edge 3a1, 3b1 of the first partition segment 3a or 3b. On each of the second partition segments 4a and 4b, the fourth folding line L4 is formed. The fourth folding line L4 extends from one end (the end point) of the second folding line L2 perpendicularly to the second folding line L2 to an inner edge 4a1, 4b1 of the second partition segment 4a or 4b. The dimension d1 of the first partition segment 3a or 3b from the second folding line L2 to the tip end and the dimension d2 of the second partition segment 4a or 4b from the fourth folding line L4 to the tip end are equal to the length of one side of the bottom plate 2. The dimensions w1 and w2 of the first partition segment 3a or 3b and the second partition segment 4a or 4b in the width direction (the direction perpendicular to the longitudinal direction) are each approximately one third of the length of one side of the bottom plate 2.
In the outer edge (facing away from the bottom plate 2) of the first partition segment 3a or 3b, two first slits 5 which are open outward are formed. In the inner edge (facing the bottom plate 2) of the second partition segment 4a or 4b, two second slits 6 which are open inward are formed. The first slits 5 are formed at such positions as to divide the part of the first partition segment 3a or 3b from the second folding line L2 to the tip end into three parts, and the second slits 6 are formed at such positions as to divide the part of the second partition segment 4a or 4b from the fourth folding line L4 to the tip end into three parts. The lengths of the first slit 5 and the second slit 6 are substantially one-half of the dimensions w1 and w2 of the first partition segments 3a and 3b and the second partition segments 4a and 4b, respectively, in the width direction.
The opening 5a of the first slit 5 and the opening 6a of the second slit 6 have a tapered shape which is increasingly wide toward the open side.

When articles are packed using the partition 1 of this embodiment, as shown in
The partition 1 of this embodiment is built by bending one sheet. This makes it possible to reduce the number of components of the partition 1 and to make it easier to build. In addition, the partition 1 is in the form of a sheet as shown in
The partition 1 has, not only the first partition segments 3a and 3b and the second partition segments 4a and 4b, but also the bottom plate 2 integrated together, and thus no bottom plate (top segment) needs to be arranged between partitions 1 when a plurality of partitions 1 are used stacked on one another.
The first partition segments 3a and 3b and the second partition segments 4a and 4b are bent in an L shape as seen in a plan view, and thus, compared with in conventional partitions in which partition segments in a rectangular strip shape are combined into a lattice, the compression strength of the first partition segments 3a and 3b and the second partition segments 4a and 4b is higher.
Further, as shown in
With the partition 1 of this embodiment, it is possible to form nine compartments and a bottom plate integrally by bending one sheet, and thus it is possible to reduce the number of components that form the partition 1. It is also possible to effectively prevent the partition 1 and the outer packing box 100 from collapsing during transportation and storage.
In this embodiment, the bottom plate 2 is square, and thus the length of the first partition segment 3a or 3b and the length of the second partition segment 4a or 4b are equal. By setting the width-direction dimension of the first partition segment 3a or 3b and the second partition segment 4a or 4b one-third of the length of one side of the bottom plate 2, the partition 1 before being built (a blank board) is, as shown in
Here, by changing the length of the first folding line L1 and the positions of the second slits 6, the size of the compartments in the row direction (the vertical direction) is changed. Instead, by changing the length of the third folding line L3 and the positions of the first slits 5, the size of any compartments in the column direction (the horizontal direction in
The embodiments described above are in no way meant to limit the present disclosure, which thus allows for many modifications and variations within the spirit of the present disclosure. For example, the partitions 1 described in the above embodiments are preferable examples, and the detailed structure of the partitions 1 such as the dimensions of the first partition segments 3a and 3b and the second partition segments 4a and 4b, and the length and positions of the first slits 5, the second slits 6, and the folding lines L1 to L4 can be changed according to the shape, size, and the like of the articles to be packed and the outer packing box 100.
The present disclosure is applicable to partitions formed by bending one sheet. Based on the present disclosure, it is possible to provide a partition which can be easily built by bending one sheet and which can form nine compartments without increasing the number of components, as well as to provide a packing material having such a partition.
