Description

The present invention relates to an improvement of a partition device that partitions a container such as a cardboard box into a plurality of parts when packaging a plurality of parts and products.

In the case of collecting and packaging a plurality of articles, partition members are widely used for the purpose of preventing damage, breakage, misalignment, and the like due to mutual interference. There are various structures of partition members formed of cardboard or cardboard, and a container such as a cardboard box is basically partitioned into a plurality of parts by fitting or bending by cutting. For example, the interior of the cardboard box is partitioned by providing a plurality of bent pieces, such as an inner partition plate of the cardboard box shown in Patent Document 1.
Japanese Utility Model Sho 55-104659

As described above, in addition to the original purpose of preventing scratches and breakage as described above, the manufacturing cost, ease of assembly, bulk during storage, self-sustainability in the container, etc. are also important requirements. This also affects the unit price of the packaged goods.

  Therefore, the present inventor has achieved the present invention as a result of intensive studies in view of the above-mentioned problems. The feature of the present inventor is that it is composed of a single sheet and mounted inside the container. In a partition member that divides a sheet into three or more, a sheet is divided into a plurality of sections in one direction, one or a plurality of parallel creases, a horizontal fold rule that continues on a straight line, and each partition area is divided into three And two vertical folding rules that are orthogonal to the cut rule and provided stepwise for each partition area at the same interval, and the adjacent horizontal folding rules are alternately mountain fold and valley fold, Each vertical fold rule in the partition area is the reverse fold of the horizontal fold rule that is continuous with the vertical fold rule that intersects the vertical fold rule closest to the edge of the sheet. The mountain folds and the valley folds adjacent to each partition area are mutually reversed.

  Here, the “compartment zone” in the present specification refers to each compartment part in which a sheet is partitioned into a plurality of sections by a cut rule and a horizontal folding rule that is continuous on a straight line. Only one horizontal folding rule that is continuous with the cut ruled line may be provided to divide the sheet into two divided areas, or two or more may be provided and divided into three or more divided areas. When a plurality of horizontal folding rules are provided, they are provided parallel to each other. The cut ruler is a rule that cuts the sheet with a cutting blade, and the fold ruled line may be a rule for making the sheet easy to bend, such as a sewing ruled line, a half-cut ruled line, and a concave groove.

  Each partition area is divided into three by providing two vertical folding rules orthogonal to the cut rules. In the partition device according to the present invention, the central portion partitioned into three is the partition. For this reason, the intervals between the two vertical folding rules provided in each partition area are all the same. Also, the two vertical folding rules are provided in a staircase shape so as not to deviate from the interval between the two vertical folding rules in the adjacent partition areas. Since the interval shifted stepwise is the pitch between the partitions, it may be arbitrarily changed according to the type of the article to be packaged other than the constant.

Examples of the sheet include cardboard, thick paper such as coated paper, plastic sheets such as polypropylene and polystyrene, foamed plastic sheets, and plastic cardboard. These sheets are provided with a cut rule, a horizontal fold rule, and a vertical fold rule, and the adjacent horizontal fold rules are folded in a so-called bellows alternately in a mountain fold and a valley fold. Then, the vertical fold rule where the intersection with the cut rule is closest to the end of the sheet is folded opposite to the horizontal fold rule that is continuous with the cut rule perpendicular to the sheet. On the basis of this vertical folding rule, the two vertical folding rules in each zone are fold-folded and valley-folded, and the adjacent zone is reversely folded. In other words, two vertical folding rules in each division area are folded in one and the other in a valley fold, and the vertical folding rules on the end side common to each division are alternately turned in a mountain fold and a valley fold. It is.

Since the partition device according to the present invention only needs to provide various rules on one sheet, it can be manufactured at a very low cost without wasting material. Since it can be configured as a partition simply by folding each vertical fold rule from a state of being folded in a bellows shape with a horizontal fold rule, the assembly takes little effort. In addition, since a self-supporting form as a partition is maintained at the stage of being attached to the container, it has a practically extremely beneficial effect such as easy storage of articles between the partitions.

The present invention solves the above-mentioned problems by providing two vertical folding rules in each of the divided areas formed by a plurality of horizontal folding rules that are continuous on the cutting rules and straight lines.

  FIG. 1 shows an embodiment of a partition device 1 according to the present invention, which is formed from a single rectangular cardboard sheet. As shown in the blank sheet of FIG. 2, the partition device 1 forms a partitioned area 3 that is partitioned into a plurality of sections by horizontal folding rules 2 provided at equal intervals from the end. Each section area 3 is provided with two vertical folding rules 4. The intervals between the two vertical creases 4 are all the same, and are provided in a staircase pattern so as to overlap between the two vertical creases 4 in the adjacent partition area 3. Further, a portion where the vertical folding ruler 4 is orthogonal to the horizontal folding ruled line 2 is a continuous cut ruled line 5. A member between the two vertical folding rules 4 in each partition area 3 serves as a partition portion 6 of the partition device 1. In the case of corrugated cardboard, the vertical crease 4 is a crease parallel to the step, so that the direction of the step is vertical.

Each horizontal fold rule 2 is made into the bellows fold which alternately made the mountain fold and the valley fold like FIG. Each vertical folding ruler 4 reversely folds the vertical folding ruled line 4 where the intersection with the cut ruled line 5 is closest from the end of the sheet to the horizontal folding ruled line 2 orthogonal thereto. Based on this, mountain folds and valley folds are alternately alternated. In the blank sheet of FIG. 2, the mountain fold is represented by a one-dot chain line, the valley fold is represented by a two-dot difference line, and the cut line 5 is represented by a thick solid line. The partition device 1 is in a folded state as shown in FIG. 3, and is pushed and expanded in the direction of the arrow shown in FIG.

Since the spread partition device 1 is self-supporting as a partition by being mounted on the container 7 as shown in FIG. 5, it is easy to store articles. The upper and lower sides of the partition device 1 may be either, and a plurality of containers 7 may be mounted as shown in FIG. Moreover, by providing a cut in the partition part 6, it is possible to install the two partition devices 1 so as to cross each other and partition them vertically and horizontally as shown in FIG.

The partition device 1 according to the present invention can be formed by simply folding it in half with one horizontal folding ruler 2 as shown in FIG. In this partition device 1, the container 7 is partitioned into three spaces by the two partition portions 6.

FIG. 9 shows still another embodiment of the partition device 1 according to the present invention, which is an example in the case where the pitch of each partition portion 6 is changed. The interval between the partition portions 6 is substantially the same as the interval between the vertical creases 4 in the adjacent partition areas 3. For example, when the interval is X> x as shown in the figure, the container 7 is divided into three narrow partition intervals and two wide partition intervals. From this, by reducing the interval between the vertical folding rules 4 in the adjacent partition areas 3, the partition 6 can be multiplexed and applied to the reinforcement of the container 7 and the fitting of the lid of the container 7.

FIG. 10 shows still another embodiment of the partition device 1 according to the present invention, and shows an example in which the height of each partition portion 6 is changed. The height of each partition 6 is determined by the width of each partition area 3. For example, if the width is Y> y as shown in the figure, the height of the two partition portions 6 at the center portion is reduced. In this case, depending on the upper and lower sides when the partition device 1 is mounted on the container 7, a gap is formed on the bottom part side or the opening part side of the container 7 in the narrow partition part 6. There is an advantage that the material can be reduced depending on the article to be packaged.
