Description

  The present invention relates to a partition plate that is housed in a box such as a returnable box or a cardboard box and divides the box, and a partition box using the partition plate.

  When storing multiple products in boxes such as returnable boxes and cardboard boxes, they are buffered to prevent damage and damage due to contact between products, and deformation and damage due to loads such as logistics, movement during storage, vibration, and stacking. Various materials are used. In general, among such cushioning materials, a partition plate made of a plate-like sheet material such as corrugated paper is widely used from the viewpoint of ease of use and economical viewpoint.

  As a partition plate using corrugated paper, for example, a partition plate of a type in which two rectangular corrugated papers are combined in a cross shape in plan view is widely used as one that partitions a box into four sections. As a partition plate for partitioning the inside of the box into four sections, a partition plate formed by assembling a piece of corrugated paper has been invented from the viewpoints of ease of assembly and reduction in the number of parts (for example, Japanese Patent Laid-Open No. 9-2000). 142450, JP-A-9-2450, etc.).

  On the other hand, in places where large numbers of returnable boxes and cardboard boxes are used, such as factories and distribution centers, various types of products are stored in fixed-size boxes. Need to change. Therefore, a plurality of types of partition plates corresponding to the number of the partitions are used. In this way, the fact that a plurality of types of partition plates are required corresponding to the size of the product, etc., because a partition plate that is not used is generated, and there is a disadvantage that it is inefficient and uneconomical. It is not preferable in terms of the environment. Therefore, there is a need for a partition plate that can handle a plurality of compartments with a single partition plate.

  In a partition plate used for a returnable box or the like, for example, as a method used for both four compartments and two compartments, the folded partition plate described in JP-A-9-142450 can be used by flattening it. Is possible. However, when the partition plate for four compartments is flattened and used, the shape is unstable, and the partition plate alone is not stably fixed to the central position inside the box such as a return box. There is a high demand in the distribution industry and the like for a partition plate that can be used by changing the number of compartments for a return box of the same size, etc., not only for use with four compartments and two compartments. However, at present, partition plates that can change the number of sections are not used from the viewpoints of shape, position in a box such as a return box, and shape stability.

JP-A-9-142450 Japanese Patent Laid-Open No. 9-2450

  The present invention has been made in view of these inconveniences, and can be transformed into a shape of two patterns of partitions capable of accommodating a box of the same size, and a partition plate excellent in its position and shape stability, and this The purpose of this is to provide a partition box using the above.

The idea made to solve the above problems is
A partition plate comprising a single sheet material and comprising a substantially rectangular first sheet material,
This first sheet material is
A first fold line provided in the width direction;
A pair of second crease lines provided on both sides of the first crease line and spaced by half the width in the width direction;
A score line provided between a pair of second crease lines on a longitudinal line that bisects the first sheet material;
And a third fold line provided in a portion other than the cut line on the longitudinal line that bisects the first sheet material.

  Since the first sheet material has the above-mentioned shape, the partition plate can form a two-partition partition by folding the first fold line into a mountain fold and making the pair of second fold lines into a valley fold. it can. Moreover, according to the said partition plate, a 4 division partition can be formed by carrying out the mountain fold of the 3rd fold line from the state which has the said 2 division partition. Thus, according to the said partition plate, it can deform | transform into the shape corresponding to the number of divisions of 2 patterns called 2 divisions and 4 divisions.

  Further, the partition plate is provided such that the second fold line is parallel to both sides of the first fold line and has an interval of ½ of the length in the width direction. Therefore, when the partition plate is used as a partition plate with any number of two patterns, the vertical and horizontal lengths do not change. Therefore, the partition plate can be accommodated in a box of the same shape without any gaps and in the box. Is excellent in position and shape stability.

  It is preferable that a plurality of width direction partition forming areas including the first fold line, the pair of second fold lines, and the cut line are formed in the longitudinal direction of the first sheet material. According to the partition plate, according to the number of width direction partition forming areas, that is, the number of first fold lines (n), by folding each first fold line into a mountain fold and making the second fold line into a valley fold. In addition, a partition of (n + 1) sections can be formed. Further, according to the partition plate, a partition of 2 (n + 1) sections can be formed by making the third fold line into a mountain fold from the state of the (n + 1) sections. Thus, according to the partition plate, it can be deformed into a shape corresponding to the number of sections of two patterns of (n + 1) sections and 2 (n + 1) sections.

  The second sheet material further includes a plurality of pairs of substantially square second sheet materials that extend from a portion other than the width direction partition formation region among both longitudinal edges of the first sheet material via a fourth fold line. It is preferable that the extension length (width direction length with respect to the first sheet material) is 1/2 of the width direction length of the first sheet material. According to the partition plate, by having such a second sheet material, the second sheet material becomes a bottom plate even when the partition of 2 (n + 1) sections is formed, and the product stored in the box Can be protected. In addition, the partition plate has an extension length of the second sheet material (width direction length with respect to the first sheet material) being ½ of the width direction length of the first sheet material. Even when the number is changed, the size of the bottom plate does not change, and it can be accommodated in a box having the same shape without gaps and not much, and the position and shape stability in the box are excellent.

  It is preferable that the substantially rectangular shape of the first sheet material has a shape in which a vertex portion is cut out from the rectangle. According to the partition plate, since the apex portion of the sheet material is cut out in this way, it can be easily stored inside the box. In addition, according to the partition plate, since the surrounding shape is formed in a straight line, there is no backlash in the box and the stability is improved, so that the buffering function of the product to be stored is improved. In addition, the partition plate can be used multiple times for a long time.

  The first and second sheet materials are preferably made of corrugated paper. The partition plate can be easily assembled by processing and folding because the sheet material is made of corrugated paper. Further, since the sheet material is made of corrugated paper, the sheet material has an appropriate thickness, so that the cushioning property is excellent and the shape is stably fixed in the box.

  Therefore, according to the partitioned box including the box and the partition plate accommodated in the box, the partition plate is changed to the number of partitions in two patterns ((n + 1) partitions and 2 (n + 1) partitions). A variety of products can be stored. Moreover, since the said box with a partition has the high position and shape stability of this partition plate, it can accommodate a product easily and efficiently.

  In the present invention, the “fold line” refers to a line that becomes a fold when the sheet material is folded, and is provided so that it can be folded as well as a line that has already been folded. It is a concept that includes a line. Further, in the present invention, “substantially rectangular” is not limited to a rectangle, but includes a shape including a shape different from a rectangle within a range in which the present invention can be implemented, such as a shape in which a vertex portion or an edge portion is cut out from a rectangle. It is.

  As described above, the partition plate of the present invention is formed from a single sheet material, and can be transformed into a shape having two patterns of partitions that can accommodate boxes of the same size. Therefore, according to the partition plate of this invention, the usage-amount of a partition plate can be suppressed and the effect excellent in the economical aspect and the environmental aspect can be exhibited. Moreover, according to the partition plate of this invention, position and shape stability can be improved. Therefore, the box with the partition plate therein can accommodate a plurality of types of products having different sizes.

It is a perspective view which shows the partition plate of FIG. 6 which has the shape for 4 divisions.

  Hereinafter, embodiments of a partition plate of the present invention and a partition box using the partition plate will be described in detail with reference to the drawings as appropriate.

  The partition plate 1 in FIG. 1 is made of a single sheet material and includes a first sheet material 2.

  The first sheet material 2 has a substantially rectangular shape having a width direction length a and a length direction length b. The size of the first sheet material 2 is not particularly limited, and is appropriately set according to the size of a return box or a cardboard box using the partition plate 1. According to the first sheet material 2, since it has a substantially rectangular shape as described above, when the partition plate 1 is assembled, the bottom portion is always linear, and the partition plate 1 is loose in the return box. It can be stored stably without any problems.

  The detailed shape of the substantially rectangular shape of the first sheet material 2 is a shape in which four vertices are cut out linearly from the rectangle. According to the first sheet material 2, the partition plate 1 has a shape in which four vertices are cut out from the rectangle in this way, so that when the partition plate 1 is stored and taken out from a return box or the like, the partition plate 1 This storing and taking out operation can be easily performed without hitting the corner of the head. The size of the notch 7 cut out in a straight line is not particularly limited, but the lower limit is preferably 0.5 cm, and particularly preferably 1 cm. Moreover, as an upper limit of the notch part 7, 6 cm is preferable and 4 cm is especially preferable. If the size of the cutout portion 7 is smaller than the above lower limit, the square of the sheet material is likely to hit the inner surface of the returnable box or the like when stored in and removed from the returnable box, etc. It does not appear. On the contrary, if the size of the notch 7 exceeds the above upper limit, although the workability at the time of storage and take-out in a returnable box or the like is improved, the linear portions of the four sides of the first sheet material 2 are reduced, When used as a partition plate, rattling is likely to occur and stability is reduced.

  The material of the first sheet material 2 is not particularly limited as long as it can form a sheet, has a certain strength and cushioning property as a material of the partition plate, and can be bent. Such as paper, synthetic resins such as polyvinyl resin, and the like can be used. Among these, cardboard, particularly cardboard, can be preferably used. Since the first sheet material 2 is made of corrugated cardboard, assembly by processing and bending can be easily performed. Moreover, since the 1st sheet | seat material 2 consists of corrugated paper, since it has moderate thickness, it is excellent in cushioning properties, and a shape is stably fixed in a box.

  The corrugated paper used for the first sheet material 2 has a structure composed of a corrugated flute and a liner bonded to one side or both sides of the flute. The flute is divided into A, B, AB, E, N flute, etc. depending on the step height and height, and the structure of the corrugated paper is appropriately determined according to the type of product stored in the return box. You can choose. For example, when a product to be stored is a product that is easily broken or easily damaged, and the partition plate 1 is required to have a high shock absorption, an A flute, an AB flute, an N flute, etc. having an appropriate thickness are preferably used. Can do. Further, when the partition plate 1 is required to have high durability, a B flute having a fine step density and a strong B flute can be suitably used. When the design property is required, an E flute suitable for printing can be preferably used.

  The first sheet material 2 has a first fold line 3 and a pair of second fold lines 4 provided in the width direction, and a cut line 5 and a third fold line 6 provided in the longitudinal direction.

  The first fold line 3 is provided in a straight line at a position that bisects the first sheet material in the width direction of the first sheet material 2. When the first crease line 3 is bent, a part of the first sheet material 2 (width-direction partition forming region 8) functions as a partition in the width direction in the partition plate shape for two sections and four sections. be able to.

  The first fold line 3 is provided for the first sheet material 2 by a known method. When the first sheet material 2 is corrugated cardboard, it can be provided by, for example, ruled line processing, or can be provided by making a cut on the surface. When the first fold line 3 is provided by making a cut on the surface, it is preferable to cut only the liner on the front surface side and to provide a depth that does not make a cut on the liner on the back surface side. By providing a crease line by such a cut, it is possible to facilitate folding and to maintain a certain strength by leaving a liner on one side. Other crease lines can be provided in the same manner.

  The second crease line 4 is provided in two straight lines on both sides of the first crease line 3 in parallel with an interval of 1/2 of the width direction length a. As a method of forming the second crease line 4, the same method as the first crease line 3 can be used. The second fold line 4 may be processed so that it can be easily bent in the direction opposite to the first fold line 3. When the second fold line 4 is bent, a part of the first sheet material 2 (width-direction partition forming region 8) functions as a partition in the width direction in the partition plate shape for two sections and four sections. be able to.

  The score line 5 is provided in a straight line between the pair of second crease lines 4 on the longitudinal line that bisects the first sheet material 2. According to the cut line 5, as will be described in detail later, the partition plate 1 can be easily deformed from the partition plate shape for two compartments to the partition plate shape for four compartments.

  The third fold line 6 is linearly provided in a portion other than the cut line 5 on the longitudinal line that bisects the first sheet material 2. As a method for forming the third fold line 6, a method similar to that for the first fold line 3 can be used. The third fold line 6 may be processed so that it can be easily bent in the same direction as the first fold line 3. According to the third fold line 6, as will be described in detail later, the partition plate 1 can be easily deformed from the partition plate shape for the two compartments to the partition plate shape for the four compartments.

  Next, the usage method of the partition plate 1 will be described. In addition, in the 1st sheet material 2, the area | region which consists of the 1st crease line 3, a pair of 2nd crease line 4, and the cut line 5 is made into the width direction partition formation area 8, and other area | regions (each 2nd crease line 4 And a region partitioned by the third fold line 6 is defined as a longitudinal partition formation region 9.

Each fold line is formed. Therefore, according to the partition plate 1, the shape for four compartments can have the same length in the longitudinal direction, the length in the width direction, and the height as the shape for the two compartments. That is, the partition plate 1 can be used as a partition for two compartments or a partition for four compartments by changing the shape of boxes of the same size. In addition, according to the partition plate 1, the vertical and horizontal lengths do not change when used as a partition with either number of sections in two patterns, so that they can be stored in a box of the same size without gaps and not much. Excellent position and shape stability.

  The partition box 11 shown in FIG. 4 has a box 12 whose inner dimensions are vertical (ba), horizontal a, depth a / 2 or more, and a shape for two compartments accommodated in the box 12. It has the partition plate 1 which has. The box 12 is not particularly limited, such as a common box made of synthetic resin or a cardboard box. Thus, by storing the partition plate 1 assembled for two compartments, the box 11 with a partition can store products and the like in two compartments.

The partition box 11 shown in FIG. 5 has a box 12 having an inner dimension of length (ba), width a, depth a / 2 or more, and a shape for four compartments accommodated in the box 12. It has the partition plate 1 which has.
As described above, when the partition plate 1 has a shape for four sections, the length in the longitudinal direction is (ba), the length in the width direction is a, and the height is a / 2, which is a size for two sections. Therefore, the partition plate 1 can be stored in the same box 12 in either of two compartments or four compartments.

  Thus, according to the partition box 11 in which the partition plate 1 is housed, the partition plate 1 can be changed to two patterns of partitions (2 partitions and 4 partitions) to store various products. can do. Moreover, since the partition box 11 has a high position and shape stability of the partition plate 1, the product can be easily accommodated.
