Description

The present invention relates to a packaging member.

Conventionally, packaging members are known in which a partition plate is arranged in a storage area of a packaging box. Such a packaging member is disclosed in Patent Document 1, for example.

Japanese Patent Application Publication No. 2009-280272

By arranging a partition plate in the storage area of the packaging box, the storage area can be partitioned into a plurality of areas. For example, objects to be packaged are stored in each of the plurality of storage areas.

Here, the partition plate may be displaced within the storage area. In this case, even though the storage area is partitioned into a plurality of areas by partition plates, the objects to be packed in each area move within the storage area and come into contact with each other, resulting in an inconvenience.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a packaging member that can suppress displacement of a partition plate.

To achieve the above object, a packaging member according to one aspect of the present invention includes a first partition plate arranged in a storage area for storing objects to be packed and extending in a first direction; a second partition plate extending in a second orthogonal direction. The first partition plate has a first slit cut from one end in the vertical direction. The second partition plate has a second slit cut from the other end in the vertical direction. By inserting the second slit into the first slit, the first partition plate and the second partition plate are intersected and connected. The first slit includes a cut surface on one side and a cut surface on the other side that face each other. The cut surface on one side has an engagement protrusion that projects toward the cut surface on the other side. The second partition plate has an engagement hole above the second slit that penetrates in the thickness direction of the second partition plate. With the second partition plate inserted into the first slit, the engagement protrusion is inserted into the engagement hole, thereby connecting the first partition plate and the second partition plate.

With the configuration of the present invention, displacement of the partition plate can be suppressed.

FIG. 9 is a diagram showing a state in which a part of the corrugated cardboard sheet shown in FIG. 8 is folded. It is a figure which shows the packaging member by a modification.

The packaging member 100 of this embodiment will be described below with reference to FIGS. 1 to 9. In the following description, the X direction in the figure is defined as the left-right direction, the Y direction is defined as the front-back direction, and the Z direction is defined as the up-down direction. The X direction (left-right direction) corresponds to a "second direction", and the Y direction (front-back direction) corresponds to a "first direction". Furthermore, in the following description, "parallel" does not necessarily have to mean parallel in a strict sense, but includes substantially parallel. Furthermore, "orthogonal" does not necessarily have to be orthogonal in a strict sense, and includes substantially orthogonal.

<Overall configuration of packaging materials>
As shown in FIGS. 1 to 3, the packaging member 100 of this embodiment has a storage area CA in which an object to be packed (not shown) is stored. The accommodation area CA is partitioned into a plurality of areas (see FIG. 2).

The packaging member 100 includes a first partition plate 1 and a second partition plate 2. Furthermore, the packaging member 100 includes a packaging box 3. The internal area of the packaging box 3 becomes the accommodation area CA. The first partition plate 1 and the second partition plate 2 are arranged in the accommodation area CA, and partition the accommodation area CA into a plurality of areas.

Note that the packaging member 100 is made of a single corrugated cardboard sheet 100S (see FIG. 8). In other words, by folding the single corrugated cardboard sheet 100S, the packaging box 3 having the first partition plate 1 and the second partition plate 2 integrally is formed. In other words, the first partition plate 1 and the second partition plate 2 are not separate from the packaging box 3. Note that each of the first partition plate 1 and the second partition plate 2 has a plate shape extending in one direction when viewed individually.

By combining the first partition plate 1 and the second partition plate 2, a partition plate P as shown in FIG. 3 is configured. In other words, the partition plate P is configured by combining mutually different parts of the single corrugated cardboard sheet 100S.

<Configuration of partition plate>
The first partition plate 1 has a structure shown in FIG. 4 when viewed from the thickness direction. The first partition plate 1 has a first slit 11 cut from the upper end (that is, one end in the vertical direction). The first slit 11 penetrates the first partition plate 1 in the thickness direction. The first slit 11 extends downward from the upper end of the first partition plate 1 . However, the first slit 11 does not reach the lower end of the first partition plate 1. Hereinafter, a portion of the first partition plate 1 below the first slit 11 (a portion left without being cut) will be referred to as a slit lower part 12. In FIG. 4, the slit lower part 12 is surrounded by a broken line.

The second partition plate 2 has a structure shown in FIG. 5 when viewed from the thickness direction. The second partition plate 2 has a second slit 21 cut from the lower end (that is, the other end in the vertical direction). The second slit 21 penetrates the second partition plate 2 in the thickness direction. The second slit 21 extends upward from the lower end of the second partition plate 2 . However, the second slit 21 does not reach the upper end of the second partition plate 2. Hereinafter, a portion of the second partition plate 2 above the second slit 21 (a portion left without being cut) will be referred to as a slit upper portion 22. In FIG. 5, the slit upper part 22 is surrounded by a broken line.

The first partition plate 1 and the second partition plate 2 are arranged to intersect with each other when viewed from above and below (see FIG. 2). For example, the first partition plate 1 and the second partition plate 2 are orthogonal to each other when viewed from above and below. In other words, the thickness directions of the first partition plate 1 and the second partition plate 2 are orthogonal to each other.

Although details will be described later, when placed in the storage area CA, the thickness direction of the first partition plate 1 is parallel to the left-right direction (X direction), and the thickness direction of the second partition plate 2 is parallel to the front-rear direction (X direction). (Y direction). In other words, when placed in the accommodation area CA, when viewed from the top and bottom, the first partition plate 1 extends linearly in the front-rear direction (Y direction), and the second partition plate 2 extends in the left-right direction (X direction). Extends in a straight line.

A first slit 11 is formed in the first partition plate 1 so that the first partition plate 1 and the second partition plate 2 intersect. Then, by inserting the second partition plate 2 into the first slit 11, the first partition plate 1 and the second partition plate 2 are intersected (orthogonal) and connected when viewed from the top and bottom.

Specifically, the slit upper part 22 of the second partition plate 2 is inserted into the first slit 11. Further, the slit lower part 12 of the first partition plate 1 is inserted into the second slit 21. The second slit 21 is formed in a portion of the second partition plate 2 that is inserted into the first slit 11. In other words, the second slit 21 is formed in a portion of the second partition plate 2 that intersects with the first partition plate 1 . The first partition plate 1 sandwiches the second partition plate 2 (slit upper part 22) between one side notch surface 111 and the other side notch surface 112 of the first slit 11 that face each other. The second partition plate 2 sandwiches the first partition plate 1 (slit lower part 12) between a pair of mutually opposing inner surfaces (numerals omitted) of the second slit 21.

Note that the first partition plate 1 and the second partition plate 2 are each erected (erected) in the vertical direction. The first partition plate 1 is arranged such that the cut opening of the first slit 11 (in other words, the opening that communicates the inside and outside of the first slit 11) faces upward. The second partition plate 2 is arranged so that the notch of the second slit 21 (in other words, the opening that communicates the inside and outside of the second slit 21) faces downward. In this case, the second partition plate 2 is inserted into the first slit 11 of the first partition plate 1 from above (see FIG. 6). As a result, the slit upper part 22 of the second partition plate 2 is arranged in the first slit 11 of the first partition plate 1, and the slit lower part 12 of the first partition plate 1 is arranged in the second slit 21 of the second partition plate 2. Ru.

In addition to forming the first slit 11 in the first partition plate 1, by forming the second slit 21 in the second partition plate 2, the lower end positions of each of the first partition plate 1 and the second partition plate 2 can be adjusted. Can be matched. Thereby, it is possible to suppress the formation of a gap below the second partition plate 2 (between the lower end of the second partition plate 2 and the bottom surface of the accommodation area CA).

In addition to forming the first slit 11 in the first partition plate 1, by forming the second slit 21 in the second partition plate 2, the upper ends of each of the first partition plate 1 and the second partition plate 2 are You can adjust the position. Thereby, it is possible to suppress the upper end of the second partition plate 2 from protruding higher than the first partition plate 1.

Note that even if the first slit 11 is formed in the first partition plate 1 but the second slit 21 is not formed in the second partition plate 2, the first partition plate 1 and the second partition plate 2 can be made to intersect. be able to.

As a modification, the first partition plate 1 may be arranged such that the cut opening of the first slit 11 faces downward. In the configuration of this modification, when forming the second slit 21 in the second partition plate 2, the second partition plate 2 is arranged so that the cut opening of the second slit 21 faces upward. In other words, the vertical positional relationship between the first partition plate 1 and the second partition plate 2 is not particularly limited.

Here, the first partition plate 1 has an engaging protrusion 110 on the cut surface 111 on one side of the first slit 11 (see FIG. 4). Specifically, a convex portion protruding toward the other side notch surface 112 is formed on the one side notch surface 111 as the engagement protrusion 110 . That is, the cut surface 111 on one side has an engagement protrusion 110 that projects toward the cut surface 112 on the other side.

Further, the second partition plate 2 has an engagement hole 210 in the slit upper part 22 (that is, above the second slit 21) (see FIG. 5). Specifically, in the slit upper part 22, a through hole penetrating the second partition plate 2 in the thickness direction is formed as an engagement hole 210. In other words, the engagement hole 210 is formed in a portion of the second partition plate 2 that is sandwiched between the cut surface 111 on one side and the cut surface 112 on the other side of the first slit 11 .

Then, as shown in FIG. 7, with the slit upper part 22 of the second partition plate 2 inserted into the first slit 11, the engagement protrusion 110 is inserted into the engagement hole 210. In other words, in a state where the slit upper part 22 of the second partition plate 2 is inserted into the first slit 11, the engagement protrusion 110 and the engagement hole 210 engage with each other. Thereby, the first partition plate 1 and the second partition plate 2 are engaged (ie, connected). In addition, in FIG. 7, the slit upper part 22 of the second partition plate 2 is shown in a cross section cut along the YZ plane.

In the configuration in which the engagement protrusion 110 and the engagement hole 210 engage with each other, even if the second partition plate 2 attempts to move upward with respect to the first partition plate 1, the upward movement of the second partition plate 2 is restricted. be done. In other words, the second partition plate 2 becomes difficult to separate from the first partition plate 1. In other words, the vertical positional relationship between the first partition plate 1 and the second partition plate 2 is less likely to collapse. Thereby, it is possible to suppress the respective positions of the first partition plate 1 and the second partition plate 2 from shifting. As a result, it is possible to suppress movement of the objects to be packed that are accommodated in the accommodation area CA. If movement of the objects to be packed in the accommodation area CA can be suppressed, damage to the objects to be packed can be suppressed.

Further, the first partition plate 1 has a recess 120 on the other side cut surface 112 of the first slit 11 (see FIG. 4). The recessed portion 120 is recessed in the protruding direction of the engagement protrusion 110 than the other portion of the other side notch surface 112 when viewed from the thickness direction of the first partition plate 1 . The engagement protrusion 110 protrudes inside the recess 120 when viewed from the thickness direction of the first partition plate 1 . That is, when viewed from the thickness direction of the first partition plate 1, at least a portion of the engagement protrusion 110 is arranged inside the recess 120. In this case, when viewed from the thickness direction of the first partition plate 1, a part of the first slit 11 is formed by the gap between the engagement protrusion 110 and the recess 120. Therefore, the first slit 11 is not linear when viewed from the thickness direction of the first partition plate 1. On the other hand, the second slit 21 extends linearly when viewed from the thickness direction of the second partition plate 2.

In the configuration in which the engagement protrusion 110 of the first partition plate 1 protrudes inside the recess 120, when the second partition plate 2 is inserted into the first slit 11 (the state shown in FIG. 7), the engagement protrusion 110 and The engagement with the engagement hole 210 becomes strong, and the engagement protrusion 110 can be prevented from falling off from the engagement hole 210. Thereby, the state in which the engagement protrusion 110 is inserted into the engagement hole 210 (in other words, the state in which the engagement protrusion 110 and the engagement hole 210 are engaged) can be reliably maintained. By holding the engagement protrusion 110 in a state inserted into the engagement hole 210, displacement of each position of the first partition plate 1 and the second partition plate 2 is suppressed.

<Packaging box configuration>
The packaging box 3 integrally includes a first partition plate 1 and a second partition plate 2. In other words, the first partition plate 1 and the second partition plate 2 are each part of the corrugated cardboard sheet 100S (see FIG. 8). In other words, in the process of folding the corrugated cardboard sheet 100S, the first partition plate 1 and the second partition plate 2 are arranged in the accommodation area CA in a state where they intersect with each other.

The packaging box 3 includes a bottom portion 30. Furthermore, the packaging box 3 includes a pair of first wall portions 31 facing each other in the left-right direction, and a pair of second wall portions 32 facing each other in the front-back direction.

The bottom portion 30 has a rectangular shape when viewed from above and below. The bottom portion 30 may have a rectangular shape or a square shape when viewed from the top and bottom. The bottom portion 30 has a pair of edges extending in the left-right direction and a pair of edges extending in the front-rear direction when viewed from the top and bottom directions.

The pair of first wall portions 31 are portions that are bent upward from each of a pair of end edges extending in the front-rear direction of the bottom portion 30 . In other words, the pair of first wall portions 31 are portions connected to each of the pair of end edges extending in the front-rear direction of the bottom portion 30, and upward from each of the pair of end edges extending in the front-rear direction of the bottom portion 30. This is the part that extends to .

The pair of second wall portions 32 are portions that are bent upward from each of a pair of end edges extending in the left-right direction of the bottom portion 30 . In other words, the pair of second wall portions 32 are portions connected to each of the pair of end edges extending in the left-right direction of the bottom portion 30, and upward from each of the pair of end edges extending in the left-right direction of the bottom portion 30. This is the part that extends to .

The upper region of the bottom portion 30 is surrounded by a pair of first walls 31 and a pair of second walls 32. The accommodation area CA is an area above the bottom 30 and surrounded by a pair of first walls 31 and a pair of second walls 32. The upper surface of the bottom portion 30 becomes the bottom surface of the accommodation area CA. A pair of surfaces of the pair of first wall portions 31 that face each other serve as inner surfaces that respectively define the range of the accommodation area CA in the left-right direction. A pair of surfaces of the pair of second wall portions 32 that face each other serve as inner surfaces that respectively define the range of the accommodation area CA in the front-rear direction.

Furthermore, the packaging box 3 includes a pair of lid portions 33. Portions extending from the upper ends of the pair of second wall portions 32 serve as lid portions 33, respectively. That is, the lid portions 33 are connected to the upper ends of the pair of second wall portions 32, respectively. The pair of lid portions 33 are each bent from the upper end of the second wall portion 32 to which they are connected, thereby closing the accommodation area CA from above.

For example, the lid portion 33 has an operation portion 330. The operating portion 330 is a notch formed in the lid portion 33. When opening and closing the lid section 33, the operator inserts his or her finger into the operating section 330.

Note that the packaging member 100 includes a connecting portion 4. The connecting portion 4 is bent in the left-right direction from the side edge of the first wall portion 31 in the front-rear direction and extends along the inner surface of the second wall portion 32 . The connecting portion 4 is connected to one side edge and the other side edge of the first wall portion 31 in the front-rear direction, respectively. Furthermore, the connecting portion 4 is connected to the pair of first wall portions 31, respectively.

Here, the first partition plate 1 is a portion of the connecting portion 4 that is bent in the front-rear direction from the side edge on the opposite side to the connection side with the first wall portion 31 and arranged in the accommodation area CA ( (See Figure 2). The second partition plate 2 is a portion of the lid portion 33 that is bent downward from the edge on the side opposite to the connection side with the second wall portion 32 and arranged in the accommodation area CA (see FIG. 6). In other words, the first partition plate 1 is a part that continuously extends from the first wall part 31 via the connecting part 4, and the second partition plate 2 is a part that continuously extends from the second wall part 32 via the lid part 33. This is the part that extends. In other words, the first partition plate 1 and the second partition plate 2 are integrally provided in the packaging box 3.

In the configuration in which the first partition plate 1 and the second partition plate 2 are integrally provided in the packaging box 3, the number of parts of the packaging member 100 can be reduced. In other words, the packaging box 3 having the first partition plate 1 and the second partition plate 2 can be obtained by simply preparing one corrugated board sheet 100S as shown in FIG.

As a modification, a portion of the connecting portion 4 that is bent in the front-rear direction from the side edge opposite to the connection side with the first wall portion 31 and arranged in the accommodation area CA is used as the second partition plate 2, and the lid The first partition plate 1 may be a portion of the portion 33 that is bent downward from the end edge on the opposite side to the connection side with the second wall portion 32 and arranged in the accommodation area CA.

The first partition plate 1 is connected to the side edge of the first wall 31 on one side in the front-rear direction via the connecting part 4, and the other side of the first wall 31 opposite to the one side in the front-rear direction The first partition plates 1 connected to the side edges of the first partition plate 1 via the connecting portions 4 are bent in opposite directions. That is, when viewed from the up-down direction, there are a first partition plate 1 extending from one side to the other side in the front-rear direction, and a first partition plate 1 extending from the other side to one side in the front-rear direction.

In this configuration, the connecting portion 4 is connected to one side edge of the first wall portion 31 in the front-rear direction and the other side edge of the first wall portion 31 opposite to the one side in the front-rear direction. The connecting portions 4 connected to each other have different lengths in the left-right direction. That is, there are a first connecting portion 41 that is shorter in the left-right direction and a second connecting portion 42 that is longer in the left-right direction than the first connecting portion 41 (see FIG. 2). Thereby, when viewed from the top and bottom, the four first partition plates 1 extending in the front-rear direction are arranged at intervals in the left-right direction (thickness direction of the first partition plate 1). In this case, the accommodation area CA is divided into five sections in the left-right direction.

That is, the packaging member 100 includes a plurality of first partition plates 1. The plurality of first partition plates 1 are connected to the side edges of the pair of first wall parts 31 via the connecting parts 4. Specifically, the plurality of first partition plates 1 include a first partition plate 1 connected to a side edge of one first wall part 31 via a connecting part 4, and a first partition plate 1 connected to a side edge of one first wall part 31 via a connecting part 4. It includes a first partition plate 1 connected to the side edge via a connecting part 4.

Then, the plurality of first partition plates 1 are bent along predetermined bending lines. In other words, each of the plurality of first partition plates 1 is bent at a boundary line with the corresponding connecting portion 4 (the boundary line becomes a predetermined bending line). As a result, the plurality of first partition plates 1 are arranged on the bottom part 30 at intervals in the left-right direction.

The packaging member 100 also includes a pair of second partition plates 2 connected to a pair of lids 33. The pair of second partition plates 2 have a plurality of second slits 21. The plurality of second slits 21 correspond to the first slits 11 of the plurality of first partition plates 1. The pair of second partition plates 2 are formed by bending downward from the edges of the pair of lid parts 33 and inserting the plurality of second slits 21 into the first slits 11 of the plurality of first partition plates 1. 1 is connected to the partition plate 1.

Specifically, a portion of one lid portion 33 that is bent downward from the edge opposite to the connection side with the second wall portion 32 and arranged in the storage area CA, and a portion of the other lid portion 33, the double portions in which the portions bent downward from the edge opposite to the connection side with the second wall portion 32 and placed in the storage area CA are overlapped in the front-rear direction are the second partition plates 2, respectively. (see FIGS. 2 and 6). That is, the two second partition plates 2 are stacked in the front-rear direction (thickness direction of the second partition plates 2). Then, the plurality of second slits 21 are inserted into the first slits 11 of the plurality of first partition plates 1 with the pair of second partition plates 2 overlapping in the front-rear direction. As a result, the double portion stands in the accommodation area CA, so that the compressive strength of the packaging member 100 in the vertical direction can be increased.

Note that in this configuration, the four first partition plates 1 partition the accommodation area CA into five sections in the left-right direction. Then, by stacking the two second partition plates 2 in the front-rear direction (thickness direction of the second partition plate 2) and using them as one partition plate, the accommodation area CA is divided into two in the front-rear direction. That is, the first partition plate 1 and the second partition plate 2 partition the accommodation area CA into ten pieces.

<Assembling packaging materials>
A developed view of the packaging member 100 is shown in FIG. FIG. 9 shows the state in the middle of assembly. In FIGS. 8 and 9, the upper surface of the bottom portion 30 (the surface on which the objects to be packaged are placed and the bottom surface of the accommodation area CA) is shown facing upward. Furthermore, in FIGS. 8 and 9, the thick solid lines are cut lines, and the broken lines are valley fold lines.

In the assembly process of the packaging member 100, first, the first wall portion 31 and a portion continuously extending from the first wall portion 31 are bent. Note that this portion includes the connecting portion 4 and the first partition plate 1. This results in the states shown in FIGS. 8 and 9. That is, the first partition plate 1 is in an upright state.

Next, the second wall portion 32 and the portion continuously extending from the second wall portion 32 are bent. Note that this portion includes the lid portion 33 and the second partition plate 2. When bending the second partition plate 2 with respect to the lid part 33, the second partition plate 2 is inserted into the first slit 11 of the first partition plate 1, as shown in FIG. The first partition plate 1 is inserted into the slit 21. Thereby, the packaging member 100 shown in FIG. 1 is obtained.

By inserting the second partition plate 2 into the first slit 11 of the first partition plate 1, the engagement protrusion 110 is inserted into the engagement hole 210. In other words, the engagement protrusion 110 and the engagement hole 210 engage with each other. Note that the lid portion 33 is connected to the second partition plate 2. Therefore, when the engagement protrusion 110 and the engagement hole 210 engage with each other, the lid 33 becomes locked (the lid 33 becomes difficult to open). This can prevent the lid portion 33 from opening unintentionally. In order to open the lid portion 33, it is necessary to intentionally release the engagement between the engagement protrusion 110 and the engagement hole 210.

Here, the two second partition plates 2 overlap each other in the front-rear direction (thickness direction of the second partition plate 2). In other words, the two second partition plates 2 face each other with an extremely narrow interval in the front-rear direction. The distance between the two second partition plates 2 in the front-rear direction is smaller than the width of the second partition plates 2 in the vertical direction. Note that the two second partition plates 2 may be in contact with each other in the front-rear direction. In this configuration, if one of the pair of lid parts 33 is not opened, it is difficult to open the other lid part 33.

Therefore, among the two second partition plates 2, one of the second partition plates 2 has an engagement hole 210 formed therein, while the other second partition plate 2 does not have an engagement hole 210 formed therein. In other words, one of the second partition plates 2 engages with the first partition plate 1, while the other second partition plate 2 does not engage with the first partition plate 1. In this configuration, one lid part 33 can be put into a locked state, but the other lid part 33 cannot be put into a locked state. However, if one lid 33 is kept in a locked state, the other lid 33 will not open. That is, if one lid part 33 is kept in a locked state, the other lid part 33 will also be in a substantially locked state. Thereby, even if the engagement hole 210 is formed in only one of the two second partition plates 2, both of the pair of lid parts 33 can be locked.

The embodiments disclosed herein are illustrative in all respects and should not be considered restrictive. The scope of the present invention is indicated by the claims rather than the description of the above embodiments, and further includes all changes within the meaning and range equivalent to the claims.

For example, in the above embodiment, the first partition plate 1 and the second partition plate 2 are integrated with the packaging box 3, but the present invention is not limited to this, and the first partition plate 1 and the second partition plate 2 may be separate from the packaging box 3. That is, as shown in FIG. 10, the packaging box 3 may be assembled first, and then the first partition plate 1 and the second partition plate 2 may be arranged in the accommodation area CA of the packaging box 3. In addition, in FIG. 10, the upper figure shows a state in which the partition plate P (the first partition plate 1 and the second partition plate 2) is not arranged in the storage area CA of the packaging box 3, and The figure below shows how the partition plate P is arranged.

Moreover, the number of each of the first partition plate 1 and the second partition plate 2 that constitute the partition plate P is not particularly limited. For example, as shown in FIG. 10, two first partition plates 1 and one second partition plate 2 may be used. In this case, the accommodation area CA can be partitioned into six areas.
