Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a partitioning material for forming a large number of partitions in a grid pattern inside a packaging box.

[Prior Art] Conventionally, in this type of partition material, as shown in FIG. 8, cuts 10 having a depth reaching the center in the width direction are provided at regular intervals in a band-shaped partition member 1d, and these cuts are 10 are combined to face each other to form a square shape, but when such a structure is set, the partition member 1d located at the bottom may fall off when it is set in a packaging box. It was difficult to handle.

In addition, as shown in FIG. 9, a belt-shaped core sheet 11 is bent and a core main body part 12 is provided in the center part, and the core main body part 12 is equally spaced on both sides. Creases 2a are provided at intervals and the core body portion 13 is formed by bending the core body portion 1.
The core main body part 12 is formed by connecting a plurality of core sheets 11 by bonding the front end surfaces of each core slave part 13 of other core sheets 11 to the other core sheets 11 in order. The heavy structure results in loss of material usage, and the overall structure is complex, so it is difficult to attach by machine, and a lot of manual work is required, resulting in low productivity.

Furthermore, as shown in Figure 10, one shape,
Prepare two sets of partition members 1e, 1f, and 1g formed by sequentially increasing the number of partition members 1e, 1f, and 1g, and arrange the partition members 1g, 1g in the center, and the partition members 1f, 1e, respectively, on the outside and facing each other. There is a known structure in which the corners of the partitions are joined and connected to each other, but such a structure requires the preparation of multiple types of partition members of different shapes and sizes. Since they had to be combined and connected in an orderly manner, there was also the problem of low productivity.

[Purpose of the invention] The present invention uses one type of finished member formed by bending a long strip sheet into a planar rectangular wave shape, so that the opening end of each booth partition of one partition member is connected to the other partition member. In order to face the closed end wall of each booth partition of the member, the glue margin formed at each bent corner of the member is pasted to the opposite closed end wall in parallel, simplifying the structure and efficiently using materials. An object of the present invention is to provide a packaging box partition material that can be formed by using the present invention.

[Structure of the invention] A plurality of fold lines are provided at regular intervals in the longitudinal direction of a belt-shaped sheet, and a cut line is provided along the center of each fold line starting from the fold line to form a partition member. By bending each fold line into a planar rectangular wave shape, a plurality of partition members are arranged in parallel with openings and closed end walls forming alternating and continuous three-sided frame-shaped partitions on both sides in the width direction, and one partition member is adjacent to the other. The corner of the closed end wall of each booth partition is brought into contact with the open end of each booth partition of the other partition member, and the glue margin formed by cutting each cut line is used to close the other partition member. It consists of a structure that is bonded and connected to an end wall.

[Function] A plurality of partition members connected in parallel have a form in which the left and right side walls at both ends of the closed end wall of each three-sided frame-shaped booth partition are perpendicular to the corner angle of each closed end wall of the opposing partition member, and the tips of the left and right side walls The open ends between the booths are closed by the closed end walls, making each booth partition into a square shape capable of accommodating articles. In such an expanded state, by holding both ends in the width direction and pressing each other inwardly, each left and right side wall is bent along the partition member, and the whole can be folded flat.

Moreover, the movement of these left and right side walls is achieved by opening the glue margin formed by cutting the score line provided along the fold line that forms the base point of each left and right side wall, and the part other than this opening plays the role of a hinge. This allows for smooth assembly.

In addition, the glue portions separated at the incision lines are pasted to the closed end walls of adjacent partition members, thereby improving the shape retention of each booth partition and further smoothing the movement of the hinges mentioned above. And make them do it accurately.

[Example] In Fig. 4, reference numeral 1 denotes a partition member formed from a band-shaped sheet such as paperboard or kraft paper. Eight fold lines 2 are provided at equal intervals in the longitudinal direction, and along each fold line 2, A cut line 3 is provided at the center of the partition member 1 in the width direction starting from the fold line 2, and as shown in FIG. The opening 4 and the closed end wall 5 are connected to the left and right side walls 6, 6 alternately at different positions.
Five continuous three-sided frame-shaped booth partitions 7 are connected, and at the same time, the portion surrounded by each fold line 2 and cut line 3 is separated at the cut line 3 to form a glue margin 8.

9 has the same width and length as the partition member 1;
This is a flat plate-shaped end wall material formed on 5/9 of the

Next, the assembly of the present invention will be explained. The partition members 1, each bent at right angles to the side surface of the end wall material 9 in a plane rectangular wave shape along the respective fold lines 2, are made to face each other as shown by the arrows in FIG. 5, and each glue margin 8 is bonded thereto. This partition member 1
As shown in FIG. 6, the partition members 1a are opposed to each other, so that the corners of each closed end wall 5 are brought into contact with the ends of each opening 4 of the partition member 1, and each glue margin 8 is connected to the other partition. It is attached to the closed end wall 5 of the member 1 or 1a.

Hereinafter, the partition members 1b and 1c are sequentially installed according to the above-mentioned procedure.
Then, by pasting each glue margin 8 of the partition member 1c to the side surface of the end wall material 9a, the assembly of the partition material A having 20 booth partitions 7 as shown in FIG. 1 is completed. .

The partition material A of the present invention formed in this manner is formed by sequentially bending the partition members 1 to 1c at right angles in a planar rectangular wave shape along each fold line 2, alternating the positions on both sides in the width direction. Since the opening 4 and the closed end wall 5 are provided, and the opposing opening 4 and the closed end wall 5 are pasted together with a glue margin 8, the material can be used without any loss, and each glue margin 8 Therefore, the closed end walls 5 connected in a linear manner are pasted to each other by the glue margin 8 of the opposing partition members 1, and a shape that is foldable at each fold line 2 and has good shape retention is obtained, even by so-called machine gluing. It can be assembled and connected efficiently.

In the case where the end wall materials 9, 9a are attached to the partition members 1 and 1c as in the embodiment, if these end wall materials 9, 9a are held in hand and operated, they can be shaped into a flat shape as shown in FIG. It is very easy to widen the folded product as shown in FIG. 1, and although not shown, it is possible to efficiently attach the product to a packaging box.

Moreover, what is shown in FIG. 7 is an embodiment in which more booth partitions 7 are provided than in the previous embodiment, and each of the partition members 1 to 1c is provided with 12 folding lines 2 and bent, and 7 Since the booth partition 7 is formed, a total of 28 compartments can be obtained using the assembled partition materials.

[Effects of the invention] As described above, the partitioning material of the present invention has a plurality of one type of partitioning members formed by bending strip sheets alternately at right angles in a planar rectangular wave shape, and the partitioning members are adjacent to each other. It has an extremely simple structure in which the open end of one partition member is closed by the closed end wall of the other partition member, and the glue allowance is attached to each other at each opposing bent corner, making it easy to form and stable in shape. The materials used are used effectively with no loss at all. Furthermore, the adhesive area is open, and the parts other than this opening function as hinges, making it easy to fold and widen, making it easy to attach to packaging boxes, and convenient for storage and transportation. It is something.
