Description

  The present invention enhances the central portion in the depth direction at the widthwise end of the rectangular box body in plan view as necessary when packing and transporting and storing electric equipment such as DVD players. It is related with the packaging box which can increase the load-bearing load by doing.

  A packaging box made of cardboard or paperboard is generally configured by connecting two inner and outer flaps that can be folded to four sides of a bottomed box body that is formed in a rectangular shape in plan view. In addition, after the two inner flaps are folded, the cover plate portion is formed by folding the two outer flaps in an overlapping manner on the outside of the inner flaps.

In this type of packaging box, as a measure for increasing its compressive strength, a partition wall continuously provided on the side plate of the box body is folded and arranged in the box body (for example, see Patent Document 1). . In addition, the upper inner flap of the box body is folded downward, the lower inner flap is folded upward, and the upper and lower inner flaps are overlapped. The part is also configured (see, for example, Patent Document 2). Furthermore, a function as a buffer piece is given to a cut and raised piece formed in a part of the inner flap of the packing case (for example, see Patent Document 3).

  In general, in a packaging box having a bottom plate portion and a lid plate portion, in addition to the original content protection function of the package, such as storing the contents, for example, electrical equipment and protecting it from collision of dust and foreign matter, It is required to have a load-bearing capacity that does not cause deformation when stacked during transportation and storage.

  In this regard, according to the technique proposed by the above-mentioned Patent Document 1, a partition wall is provided in the box body, and the partition wall is interposed between the bottom plate portion and the lid plate portion of the box body. Therefore, the reinforcing action of the partition wall helps to increase the load carrying capacity. However, this is because the partition wall is connected to the side plate of the box body, so that not only an extra material is required for constituting the partition wall, but the partition wall is abbreviated inside the box body. Since it extends over the whole area, one accommodation space over the whole box body cannot be secured. For this reason, it is difficult to put it into practical use as a packaging box for housing electrical equipment such as a DVD player.

  Further, in the technique proposed by Patent Document 2, it is considered that the load carrying capacity can be increased by the hollow buffer portions formed at both ends in the width direction of the box body. Is used for the buffer portion, the bottom plate portion is formed only by the outer flap, and it is difficult to give sufficient strength to the bottom plate portion.

  On the other hand, with regard to packaging boxes whose contents are electrical products, there is a risk that the load bearing capacity of the packaging box in which the electrical products are planned to be stored is insufficient immediately before or after the start of mass production of electrical products. May arise. And when such a problem emerges, as a countermeasure, a reinforcement member manufactured separately from the packing box may be put in the packing box to improve its load resistance, but it was manufactured separately. When the reinforcing member is used, it is inevitable that the cost is increased accordingly.

  By the way, since the thing proposed by the above-mentioned patent document 1 has the partition wall which exhibits a permanent reinforcement effect | action, the choice of using the partition wall as needed or not using it There is no room for it. Therefore, it is always necessary to assemble the partition wall.

  Therefore, the present invention is a problem related to load resistance that may occur immediately before or after the start of mass production of contents such as electric products, that is, it is unknown at the design stage of the contents and may be found only after the mass production. A packaging box that can flexibly deal with problems with load carrying capacity, in other words, it can be used with increased load carrying capacity only when needed, without the use of separately manufactured reinforcing members. Nevertheless, it is an object of the present invention to provide a packaging box that can be used without increasing the load resistance when it is not necessary to increase the load resistance. In particular, the present invention relates to a packaging box that is capable of reinforcing the central portion in the depth direction at both ends in the width direction of the packaging box and taking measures to increase the load resistance as necessary. It is.

  The packaging box according to the present invention is a foldable in which at least one of a lid plate portion and a bottom plate portion of a bottomed box main body formed of a cardboard in a rectangular shape in plan view is connected to four sides of the box main body. These two inner flaps and two outer flaps that can be folded outside the inner flaps. And it has a support piece that is interposed between the lid plate portion and the bottom plate portion by being arranged at the center in the depth direction at the lateral width direction end of the box body, and increases the load resistance. A piece is defined in the inner flap by a cut formed in the inner flap, and a non-cut portion without the cut is provided at one end in the height direction of the support piece, through the cut-free portion. The support piece is connected to the inner flap so as to be bendable.

  According to the present invention, the support piece that is disposed between the lid plate portion and the bottom plate portion by being disposed in the center portion in the depth direction at the lateral width direction end portion of the box body has an inner flap. The inner flap is defined by a cut formed in the inner flap, and an end portion without the cut is provided at one end in the height direction of the support piece, and the support piece is inserted through the no-cut portion. When it is not necessary to increase the load carrying capacity by being connected to the inner flap so that it can be bent, the support piece can be used as a part of the lid plate portion or the bottom plate portion formed by the inner flap. Since it is possible, by doing so, it becomes possible to omit the trouble of bending the support piece and disposing it in the middle part in the longitudinal direction of the box body. On the other hand, when it is necessary to increase the load-bearing load, it is possible to cope with the necessity by simply folding the support piece and disposing it at the center in the depth direction at the lateral width direction end of the box body. Therefore, the packaging box according to the present invention flexibly copes with the problem of the load carrying capacity that is unknown at the design stage of contents such as electric products and may be found for the first time immediately before or after the start of mass production. It becomes possible.

  In the present invention, the inner flap has a width extending over the entire length of the side portion where the inner flap is connected, and the support piece is defined in the center in the depth width direction of the inner flap. It is desirable. If it is this composition, a support piece will be certainly arranged in the longitudinal direction middle part of a box body, and a box body will be reinforced, only by folding a support piece with respect to an inner flap, and folding an inner flap, such a thing. The load capacity can be increased through reinforcement of the corner.

  In the present invention, the support piece has a plurality of sections arranged in the width direction of the inner flap, and the one end of the support piece in the height direction is only one section of the plurality of sections, and the uncut portion. It is desirable that the support piece can be bent at the boundary line between the adjacent compartments. According to this, it is possible to bend the support piece to form a plurality of sections into a three-dimensional hollow columnar shape, etc., and thereby to reinforce the central part in the depth direction at the lateral width direction end of the box body It becomes possible to significantly increase the load carrying capacity by exerting the effect remarkably.

  In the present invention, the support piece has first and second sections arranged in the width direction of the inner flap, and one end in the height direction of the support piece is the first section alone and the cut-free portion. The second section of the support piece is formed so as to be foldable on the first section side at the boundary line with the first section. It is also possible to adopt the configuration described above, and this also makes it possible to significantly increase the load carrying capacity by significantly exerting the reinforcing action of the central portion in the depth direction at the end in the width direction of the box body.

  In the present invention, the support piece has first, second and third sections arranged in the width direction of the inner flap, and one end portion in the height direction of the support piece has the first section and the third section. Only the second section sandwiched between the sections is connected to the inner flap so as to be foldable via the uncut portion, and the first section and the third section of the supporting piece are the second section. It is also possible to adopt a configuration in which it is formed to be foldable on the second partition side at the boundary line with this, and also by this, the reinforcing action of the central part in the depth direction at the lateral width direction end part of the box body It is possible to significantly increase the load-bearing load by exerting it remarkably.

  The packaging box according to the present invention includes two foldable inner flaps in which a cover plate portion of a bottomed box body formed of cardboard in a rectangular shape in plan view is connected to four sides of the box body. In a packaging box formed by two outer flaps that can be folded outside the inner flap, the two inner flaps have a width extending over the entire length of the side where the inner flaps are connected. Are disposed between the lid plate portion and the bottom plate portion at the center portion in the depth direction at the end portion in the width direction of the box body at the center portion in the depth width direction of each of the inner flaps. The support piece for increasing the load-bearing load is defined in the inner flap by the cut formed in the inner flap, and the support piece has an uncut portion that does not have the cut at one end in the height direction. The part without the cut The support piece is connected to the inner flap in a foldable manner, and the support piece has first and second sections arranged in the width direction of the inner flap, and the height of the support piece. One end portion in the direction is connected to the inner flap so as to be foldable through the uncut portion only in the first section, and the second section of the support piece is a boundary line with the first section. The present invention is further embodied by adopting a configuration in which the first section is formed so as to be bent at a right angle or a substantially right angle. The operation of the present invention will be described in detail with reference to embodiments described later.

  As described above, according to the present invention, it becomes possible to flexibly cope with the problem relating to the load bearing capacity that can occur for the first time immediately before or after the start of mass production of contents such as electric products, and the need arises. It is possible to provide a packaging box that can be used with increased load resistance without using a separately manufactured reinforcing member. Further, since the support piece can be formed using the inner flap, it is not necessary to use an extra material as seen in Patent Document 1 listed at the beginning.

Moreover, FIG. 6 is a principal part top view of the packaging box A by a modification.

  The packaging box A of this embodiment is made of cardboard, and the lid plate portion 20 of the bottomed box body 10 formed into a rectangular shape in plan view is formed by four sides 11 of the box body 10 as shown in FIG. , 12, 13 and 14 are formed by two foldable inner flaps 21 and 22 and two outer flaps 23 and 24 which can be folded outside the inner flaps 21 and 22. . Among these, each of the two inner flaps 21 and 22 located at both ends in the width direction W of the box body 10 extends over the entire length of the two side portions 11 and 12 of the box body 10 to which they are connected. It has a depth width. Further, the box body 10 is provided with the above-described cover plate portion 20, as well as a bottom plate portion 30 and a trunk plate portion 40. And the trunk | drum board part 40 has each side plate 41,42,43,44 of front, back, left, and right, and the bottom plate part 30 is connected in the side part of the lower side of each side plate 41-44 among two sheets. The flaps 31 and 32 are formed by two outer flaps 33 and 34 folded in an overlapping manner on the outer side (lower side) of the inner flaps 31 and 32.

  In the above, after putting the electric equipment etc. which are the contents in the box main body 10, and bundling the cushioning material as needed, the inner flaps 21 and 22 are folded, and the outer flap 23, Folding 24 is used for the packaging box A. In addition, such a packing box A may be kept in a loaded state during transportation or storage, and in that case, the packing box A is provided with a load resistance that does not cause deformation. Is required.

  However, the load capacity may be required to exceed the originally planned load capacity immediately before or after the start of mass production of contents. Therefore, in the packaging box A of this embodiment, measures are taken that can increase the load resistance without using a separately manufactured reinforcing member, if necessary. Hereinafter, this point will be described.

  As can be seen by referring to FIG. 5 illustrating the developed view, the packaging box A of this embodiment is a component of the bottom plate 30 on the lower sides of the four side plates 41 to 44 formed side by side with cardboard. The two inner flaps 31, 32 and the two outer flaps 33, 34 are distributed and continuously arranged, and the upper side portions of the four side plates 41 to 44 are components 2 of the lid plate portion 20. The two inner flaps 21 and 22 and the two outer flaps 23 and 24 are distributed and connected.

  Further, in the packaging box A of this embodiment, as shown in FIG. 4, support pieces 60 are provided at two positions in the center portion in the depth direction D at both ends in the width direction W of the box body 10, and the support pieces 60 are arranged. Basically, the load resistance of the packing box A is increased by adopting a means of interposing between the bottom plate portion 30 and the lid plate portion 20. Then, a countermeasure is taken in which the support pieces 60 are distributed and provided on the two inner flaps 21 and 22 which are constituent elements of the lid plate portion 20 two by two.

  Of the support pieces 60 that are divided and provided on each of the two inner flaps 21 and 22, a method of forming the support piece 60 will be specifically described by taking one support piece 60 formed on the inner flap 21 as an example. As shown in FIG. 5, the support piece 60 is partitioned and formed at the center in the depth width direction D ′ of the inner flap 21 by a cut 70 formed in the inner flap 21. In the illustrated example, the cut line 70 is formed on the side portion 11 across one end portion of the two first cutting lines 71, 71 parallel to the side of the inner flap 21 and the two first cutting lines 71, 71. A parallel second dividing line 72; a third dividing line 73 extending from the other end of the first dividing line 71 on one side toward the other end of the first dividing line 71 on the other side and parallel to the side 11; A portion extending between the end point of the third dividing line 73 and the other end portion of the first dividing line 71 on the other side is formed as an uncut portion 74. Therefore, in the support piece 60 in the standing posture formed by bending inwardly with respect to the inner flap 21 at the uncut portion 74, the uncut portion 74 is formed in the height direction H (see FIG. 3)). Further, the height (length) of the support piece 60 is matched with the facing distance between the bottom plate portion 30 and the lid plate portion 20 of the packaging box A.

  In the support piece 60 formed at the end of the inner flap 21 in the lateral width direction W as described above, the second dividing line from the position indicated by the broken line in FIG. 72, two sections arranged in the width direction W of the inner flap 21 with the line i reaching the middle point 72 as a boundary, that is, the first section A1 and the second section A2 are provided. The second section A2 can be bent or folded at a right angle with respect to the first section A1. The other support pieces 60 have the same configuration.

  In the packaging box A having the above configuration, when it is necessary to increase the load resistance, as shown in FIG. 2 and FIG. 3, the support piece 60 provided on one inner flap 21, Bending the uncut portion 74 located at one end in the height direction of the first section A1 (corresponding to the height direction H of the box body) inwardly at a right angle as indicated by an arrow a; When the section A2 is folded back with respect to the first section A1 as indicated by an arrow b and the inner flap 21 is folded inward, the lower end of the support piece 60 is abutted against the bottom plate portion 30. The same applies to the other support pieces 60. By doing so, the support pieces 60 are respectively provided at the center portions in the depth direction D at both ends in the width direction W of the box body 10, and the packing box A is placed in the width direction W by these support pieces 60. Reinforced on both sides, the load carrying capacity of the packing box A increases.

  2, 3, and 4, the example in which the second section A <b> 2 of the support piece 60 is folded back at an angle larger than a right angle with respect to the first section has been described. The second section A2 of the support piece 60 may be bent at a right angle to the first section.

  7 is a plan view of a packaging box A provided with support pieces 60 according to another modification, FIG. 8 is a sectional view taken along line VIII-VIII in FIG. 7, and FIG. 9 is a development view of the packaging box A in FIG.

  7-9 has the 1st, 2nd, and 3rd division A1, A2, A3 in which the support piece 60 was located in a line with the width direction of the inner flaps 21 and 22, Among them, One end in the height direction of the center second section A2 is connected to the inner flaps 21 and 22 so as to be foldable via a not-cut portion, and the first section A1 and the third section of the support piece 60 are also provided. A3 is formed to be foldable on the second section side at the boundary line with the second section A2. When the support piece 60 has this configuration, as shown in FIG. 7, the first section A1 and the third section A3 of each support piece 60 of the folded inner flaps 21 and 22 with respect to the first section A2. As a result, the three-dimensional support piece 60 is formed, and the support piece 60 is interposed between the bottom plate portion 30 and the cover plate portion 20 as shown in FIG. The center part in the depth direction D is reinforced at both ends in the direction W, and the load resistance of the packaging box A increases. Other matters are the same as those described with reference to FIGS.

  In each of the embodiments described above, the example in which the support piece 60 is provided in the inner flaps 21 and 22 that are the constituent elements of the lid plate portion 20 has been described, but the inner flap 31 that is the constituent element of the bottom plate portion 30 is described. , 32 can also be provided. The reason why the support pieces 60 are provided on the inner flaps 21 and 22 is that the openings S (see FIG. 2) remaining in the folding marks of the support pieces 60 are covered with the outer flaps 23 and 24 and cannot be seen. This is because the opening S is closed by 23 and 24, and intrusion of dust or the like can be prevented.
