Description

  In the present invention, when packing and transporting and storing a packaging box, especially an electric device such as a DVD player, it is possible to enhance the resistance by reinforcing the middle part in the longitudinal direction of the rectangular box body in plan view as necessary. The present invention relates to a packaging box capable of increasing a load capacity.

  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, various countermeasures for reinforcing the corner portion have been conventionally proposed (see, for example, Patent Document 1 and Patent Document 2). In those proposed by Patent Document 1 and Patent Document 2, four corner portions are selected as reinforcing points. And in patent document 1, it is proposed to interpose a reinforcement part integrally between each of four side surfaces, bend the reinforcement part in a triangle, and to arrange | position to a corner part, and patent document 2 WHEREIN: A side plate is proposed. It has been proposed to provide a columnar support portion formed by cutting and raising a part of the box at a corner portion of a box-shaped body.

  In the field of fast food take-out packaging boxes, it has been proposed to reinforce the lid top plate by forming a double folded portion on the lid top plate. (For example, refer to Patent Document 3).

Furthermore, in a packaging box that does not have a cover plate portion, a packaging box that can be stacked by bending a reinforcing plate connected to a side plate into a triangular shape in plan view has been proposed (for example, (See Patent Document 3 and Patent Document 4).

  However, the techniques proposed by the above-mentioned Patent Documents 1 and 2 are useful for reinforcing the corner portion of the packaging box to increase its body load, but reinforcing the middle portion in the longitudinal direction of the packaging box. It is difficult to apply to do. Moreover, it is indispensable that the reinforcement part described in Patent Document 1 is permanently installed in the packaging box, and is not such that it can be appropriately installed as necessary. In other words, when assembling the packaging box, it is necessary to always arrange the reinforcing portion at the corner of the box body. Even if the reinforcing portion is omitted, the packaging box without the reinforcing portion cannot be assembled. Moreover, since what is described in Patent Document 2 forms the columnar support portion by cutting and raising the side plate, the opening formed in the cut and raised trace of the columnar support portion remains as it is. As a result, the strength of the side plate is lowered, and it can be said that it is difficult to obtain an increase in the load resistance as a whole. Furthermore, since what is described in Patent Document 3 merely reinforces the lid top plate or the like with a double folded portion of cardboard, the effect of increasing the load resistance cannot be expected so much.

  On the other hand, in the case of 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.

  However, regarding the case where the contents are electrical products, there is a risk that the load bearing capacity of the packaging box in which the electrical products are 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. In addition, when taking measures to satisfy the load-bearing capacity of the packing box using a separately manufactured reinforcing member immediately before the start of mass production of the contents, the reinforcing member is attached to both longitudinal ends and corners of the packing box. In some cases, a satisfactory load resistance cannot be obtained depending on the incorporation, and in that case, a means may be taken to satisfy the load resistance by incorporating a reinforcing member in the middle portion in the longitudinal direction of the packaging box.

  By the way, what is proposed by each of the above-mentioned patent documents has a permanent reinforcing part, so there is no choice of using or not using the reinforcing part as necessary. . Therefore, it is always necessary to assemble a reinforcing part and a reinforcing plate.

  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 in which measures can be taken so that the load carrying load can be increased as necessary by reinforcing the intermediate portion in the longitudinal direction of the packaging box.

  The packaging box according to the present invention can be folded such that at least one of the cover plate portion and the bottom plate portion of the bottomed box body formed of cardboard in a rectangular shape in plan view is connected to the four sides of the box body. These two inner flaps and two outer flaps that can be folded outside the inner flaps. And it has the support piece which is interposed between the said cover plate part and the bottom plate part by being arrange | positioned in the longitudinal direction intermediate part of the said box main body, and increases a load resistance, The support piece is the said inner flap. The inner flap is defined by the cut formed in the inner flap, and the support piece is provided with an uncut portion having no cut at one end in the height direction of the support piece, and the support piece is inserted through the uncut portion. It is connected to the inner flap so that it can be bent.

  According to the present invention, the support piece that is disposed between the lid plate portion and the bottom plate portion and is disposed in the middle portion in the longitudinal direction of the box body to increase the load resistance is formed on the inner flap. The inner side of the support piece is formed with a section having no cuts at one end in the height direction of the support piece, and the support piece is bent to the inner flap through the no-cut part. Since it is possible to use the support piece as a part of the lid plate portion or the bottom plate portion formed by the inner flap when it is not necessary to increase the load carrying capacity by being continuously provided, By doing so, it becomes possible to omit the trouble of bending the support piece and arranging 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 deploying it in the middle portion in the longitudinal direction 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 lateral width over the entire length of the side portion where the inner flap is continuously provided, and the support pieces are partitioned at both ends in the width direction of the inner flap. 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 lateral 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 cut-free 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 and form the plurality of sections into a three-dimensional hollow columnar shape, etc., and thereby remarkably exhibit the reinforcing action of the middle part in the longitudinal direction of the box body This makes it possible to significantly increase the load carrying capacity.

  In this invention, the said support piece has two divisions located in a line in the width direction of the said inner flap, and the one end part of the height direction of the support piece is located inside the inner flap of two said divisions. The inner section is foldably connected to the inner flap through the uncut portion only, and the outer section of the support piece can be bent to the inner section at the boundary with the inner section. It is also possible to adopt a configuration that is formed in the box, which also makes it possible to significantly increase the load carrying capacity by significantly exerting the reinforcing action of the middle part in the longitudinal direction of the box body. .

  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 over the entire length of the side part where the inner flaps are connected. In addition, the inner flaps are disposed at both ends in the width direction of the inner side in the longitudinal direction of the box body so as to be interposed between the lid plate portion and the bottom plate portion to increase the load resistance. A support piece is defined in the inner flap by a cut formed in the inner flap, and an uncut portion without the cut is provided at one end in the height direction of the support piece, and the cut-off portion is Via the support piece The inner side flap is connected to the inner flap so that it can be bent, and the support piece has two sections arranged in the width direction of the inner flap, and one end in the height direction of the support piece is one of the two sections. Only the inner section located on the inner side of the inner flap is connected to the inner flap so as to be foldable via the uncut portion, and the outer section of the support piece is a boundary line with the inner section. Further, it is further embodied by adopting a configuration in which it can be bent at right angles or substantially right angles on the inner partition side. 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.

  FIG. 1 is a schematic perspective view of the packaging box A according to the embodiment of the present invention in a state where the support piece 60 is not used, and FIG. 2 is a state where the support piece 60 is used in the packaging box A according to the embodiment. FIG. 3 is a plan view of the packaging box A of FIG. 2, and FIG. 4 is an exploded view of the packaging box A of FIG.

  As shown in FIG. 1 or FIG. 2, the packaging box A of this embodiment is made of cardboard, and the cover plate portion 20 of the bottomed box body 10 formed in a rectangular shape in plan view includes four pieces of the box body 10. Formed by two foldable inner flaps 21, 22 connected to the sides 11, 12, 13, 14 and two outer flaps 23, 24 foldable outside the inner flaps 21, 22. Has been. Among these, each of the two inner flaps 21 and 22 located at both ends in the longitudinal direction X of the box body 10 extends over the entire length of the two sides 11 and 12 of the box body 10 to which they are connected. It has a 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. 4 illustrating the developed view, the packaging box A of this embodiment has components of the bottom plate portion 30 on the lower side portions 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.

  Moreover, in the packaging box A of this embodiment, it is each in four places of the intermediate part in the longitudinal direction X inside the box main body 10, ie, four places of the intermediate part in the longitudinal direction X of the box main body 10 as shown in FIG. Basically, the load capacity of the packing box A is increased by employing a means in which the support piece 60 is provided and the support piece 60 is interposed 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, one support piece 60 of the inner flap 21 shown partially enlarged in FIG. This will be specifically described. As shown in FIG. 5, the support piece 60 is partitioned and formed at the end portion in the lateral width direction W of the inner flap 21 by a cut 70 formed in the inner flap 21. In the illustrated example, the cut 70 has a first point on the side 11 of the side plate 41 that is parallel to the side of the inner flap 21 and reaches the intermediate portion in the widthwise direction of the inner flap 21 from the side 11. A dividing line 71, a second dividing line 72 cut from the side of the inner flap 21 on the side 11 at a right angle to the starting point of the first dividing line 71, and a first dividing line from the side of the inner flap 21 And a third slicing line 73 cut at a right angle in the direction approaching 71, and a portion extending between the end point of the third slicing line 73 and the end point of the first slicing line 71 is defined as an uncut portion 74. Is formed. 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. 2 or 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.

  As described above, in the support piece 60 formed at the end portion of the inner flap 21 in the width direction W, the portion indicated by the broken line in FIG. 4, that is, from the end point of the third dividing line 73 to the side portion 11. Two compartments arranged in the width direction W of the inner flap 21 with the line I reaching as a boundary, that is, the outer compartment A1 and the inner compartment A2 are provided, and at the line I, outside the inner compartment A2. It is possible to bend or fold the section A1 at a right angle.

  Since the other three support pieces 60 have the same configuration, description of a specific configuration of each support piece 60 is omitted.

  In the packaging box A having the above configuration, when it is necessary to increase the load resistance, as shown in FIG. 2, the two support pieces 60 and 60 provided at both ends in the width direction of one inner flap 21 are shown. When the uncut portion 74 located at one end in the height direction H of the inner section A1 of the support piece 60 is bent inward at a right angle, the lower ends of the support pieces 60 and 60 are butted against the bottom plate portion 30. The other two support pieces 60, 60 are bent in the same manner. As a result, the support pieces 60 are arranged at four locations, and the support pieces 60 reinforce the intermediate portion in the longitudinal direction X of the packaging box A, thereby increasing the load resistance of the packaging box A. Will do.

  In this embodiment, the support piece 60 is provided with two sections, an outer section A1 and an inner section A2, so that the outer section A1 can be bent at a right angle with respect to the inner section A2. When the outer section A1 is bent with respect to the inner section A2, the support piece 60 itself forms an angled three-dimensional shape and the reinforcing action is improved accordingly. Further, in this embodiment, the outer section A1 can be bent at a right angle with respect to the inner section A2, so that the support plate 60 is separated from the side plate 43 at the bottom plate portion 30 and the lid plate portion 20. Intervening between each other. Therefore, the reinforcing action by the support piece 60 is easily spread over the entire cover plate portion 20, and as a result, there is an advantage that it is easy to suppress the cover plate portion 20 from being partially recessed due to the load. .

  In this embodiment, the support piece 60 has been described as having two sections, the outer section A1 and the inner section A2. However, in the present invention, a plurality of sections arranged in the width direction of the inner flap on the support piece. Can be provided. And in that case, when adopting a configuration in which one end in the height direction of the support piece is continuously connected to the inner flap through the uncut portion in only one section of the plurality of sections, It is also possible to bend the plurality of sections to form a three-dimensional hollow column or the like. By doing so, the reinforcing action is more remarkably exhibited.

  Further, in the above-described embodiment, the example in which the support piece 60 is provided on the inner flaps 21 and 22 that are the constituent elements of the lid plate portion 20 has been described, but the support pieces are the inner flaps 31 and 22 that are the constituent elements of the bottom plate portion 30. 32 can also be provided.

  Furthermore, the reason why the support pieces 60 are provided in the inner flaps 21 and 22 is that the opening S (see FIG. 2) remaining in the folding trace of the support pieces 60 is 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.

It is a schematic perspective view in the state where the support piece is not used in the packing box concerning the embodiment of the present invention. It is a schematic perspective view in the state which is using the support piece in the packaging box which concerns on the embodiment. It is a top view of the packaging box of FIG. It is an expanded view of the packaging box of FIG.
