Description

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

In general, a packaging box made of cardboard or paperboard has two inner and outer flaps that can be folded at the four sides of the box body of the rectangular cylinder of the box body. It is configured by connecting. The bottom plate portion and the cover plate portion are formed by folding two inner flaps and then folding two outer flaps 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, Patent Document 2, and Patent Document 3). That is, in those proposed by these patent documents, four corner portions of the trunk portion or a corner portion formed by the trunk portion and the lid plate portion is selected as the reinforcing portion.
JP 2003-1555025 A JP-A-11-105855 JP-A-9-77176

  However, although the technique proposed by the above-mentioned patent document is useful for reinforcing the corner portion of the packaging box to increase its load-bearing load, the end in the depth direction is reinforced at the middle portion in the lateral width direction of the packaging box. It is difficult to apply to do. Further, when assembling the packaging box, it is necessary to always provide the reinforcing portion at the corner portion of the box body.

  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, in the case where the contents are electrical products, a load test is performed on the packaging box in which the electrical products are to be stored prior to the start of mass production. In many cases, results are obtained when the start of mass production of electrical products is imminent or immediately after the start of mass production. Therefore, when the start of mass production of electrical products is imminent, if a strength deficiency is found in the results of a load test on the packaging box, as a countermeasure, a reinforcing member manufactured separately from the packaging box Sometimes, a (cardboard pad) is placed in a packing box to improve its load carrying capacity. However, there is a problem that using such a separately produced reinforcing member inevitably increases the cost.

  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 a depth direction end can be reinforced at an intermediate portion in the lateral width direction of the packaging box, and measures are taken to increase the load resistance as necessary. It is.

  In the packaging box according to the present invention, each of the cover plate portion and the bottom plate portion of the box body formed of cardboard in a rectangular shape in plan view is connected to the four side portions of the rectangular cylindrical body portion of the box body. It is formed by two foldable inner flaps and two outer foldable flaps 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 end in the depth direction at the intermediate portion in the width direction 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 forming the lid plate portion, and a non-cut portion having no cut is provided at the base end of the support piece. In addition to the support piece being foldably connected to the inner flap forming the lid plate portion via the cut-free portion, the cut-free portion is connected to the inner flap of the bottom plate portion. A protrusion piece provided at the tip of the support piece interposed between the cover plate portion and the bottom plate portion is inserted to be bent, and an insertion hole for restricting the position of the support piece is provided.

  According to the present invention, the support piece that is disposed between the lid plate portion and the bottom plate portion by being disposed at the end in the depth direction at the intermediate portion in the width direction of the box body has an inner flap. The inner flap is defined by a notch formed in the inner flap, and a non-cut portion without the cut is provided at a base end portion of the support piece, and the support piece is connected to the inner flap through the no-cut portion. When it is not necessary to increase the load capacity, the support piece can be used as a part of the cover plate or bottom plate formed by the inner flap. Therefore, by doing so, it is possible to omit the trouble of bending the support piece and disposing it at the end portion in the depth direction at the middle portion in the width 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 only by bending the support piece and disposing it at the end portion in the depth direction at the intermediate portion in the width 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 addition to this, in the packing box of the present invention, in particular, at the front end portion of the support piece interposed between the lid plate portion and the bottom plate portion by bending the notched portion on the inner flap of the bottom plate portion. Since the structure that the projecting piece portion provided is provided with an insertion hole for restricting the position of the support piece is added, it is arranged inside the packing box to increase its load resistance It is necessary to increase the load resistance of the packing box because the useful support piece can be prevented from moving and being displaced later and the reinforcing action of the support piece being lost. It will be possible to meet the demands at certain times. In addition, since the opening remaining in the trace of the support piece is closed by folding the outer flap, a situation in which dust enters from the opening or the contents collide with the foreign matter through the opening does not occur.

  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 width direction of the inner flap, and the base end portion of the support piece is only one section of the plurality of sections via the uncut portion. It is desirable that the inner flap is foldably connected to the inner flap and 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 structure, and by doing so, the reinforcing action of the end portion in the depth direction at the intermediate portion in the width direction of the box body is remarkable. 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 inner side which the base end part of the support piece is located inside the inner flap of two said divisions The section is connected to the inner flap so as to be foldable through the uncut portion, and the outer section of the support piece is formed to be foldable to the inner section at the boundary line with the inner section. It is also possible to employ a configuration in which the load carrying load can be significantly increased by significantly exerting the reinforcing action of the intermediate portion in the longitudinal direction of the box body.

  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.

  In particular, according to the present invention, the protruding piece provided at the tip of the support piece interposed between the lid plate portion and the bottom plate portion is inserted into the inner flap of the bottom plate portion by bending the uncut portion. In order to increase the load capacity of the support piece that is installed inside the packaging box, the support piece moves afterwards. Since the situation that the position shifts and the reinforcing action by the support piece is damaged is prevented in advance, it is possible to reliably meet the demand when it is necessary to increase the load resistance of the packing box. An excellent action or effect is achieved.

  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.

  The packaging box A of this embodiment is made of cardboard, and as shown in FIG. 1 or FIG. 2, the lid plate portion 20 of the bottomed box body 10 formed into 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 lateral width direction X 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 width. Further, the box body 10 includes the bottom plate portion 30 and the body portion 40 in addition to the lid plate portion 20. The body 40 has front, rear, left and right side plates 41, 42, 43, 44, and the bottom plate 30 is connected to the lower side of each side plate 41 to 44 with two inner flaps. 31, 32 and two outer flaps 33, 34 folded in an overlapping manner on the outer side (lower side) of the inner flaps 31, 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.

  Further, in the packaging box A of this embodiment, the middle part in the lateral width direction X inside the box body 10, that is, the end in the depth direction Y at the middle part in the lateral width direction X of the box body 10 as shown in FIG. 3. The load capacity of the packaging box A is increased by adopting a means in which support pieces 60 are arranged at four locations of the part and the support pieces 60 are interposed between the bottom plate portion 30 and the cover plate portion 20. It is based on that. 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. 4, the support piece 60 is partitioned and formed at the end of the inner flap 21 in the lateral width direction (corresponding to the depth direction Y) 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, the side portion 11 is reached from the position indicated by the broken line in FIG. 4, that is, from the end point of the third dividing line 73. Two sections arranged in the widthwise direction of the inner flap 21 with the line A as a boundary, that is, an outer section A1 and an inner section A2 are provided, and the outer section A1 with respect to the inner section A2 at the line A. Can be folded or folded at right angles.

  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 the base end portion in the height direction H of the inner section A2 of the support piece 60 is bent at a right angle inside, the lower ends of the support pieces 60 and 60 are abutted against the bottom plate portion 30. The other two support pieces 60, 60 are bent in the same manner. By doing so, the support pieces 60 are arranged at four locations, respectively, and the end portions in the depth direction Y are reinforced by the support pieces 60 at the intermediate portion in the lateral width direction X of the packing box A, and the packing box A. This increases the load carrying capacity.

  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. .

  Here, in this embodiment, as shown in FIG. 2 or FIG. 4, the tip end portion of the support piece 60 is formed as a protruding piece portion 61. On the other hand, a slit-like or slit-like insertion hole 35 into which the protruding piece portion 61 can be inserted is formed in the inner flap 31 of the bottom plate portion 30. Then, as described above, after the uncut portion 74 is folded and the inner flap 21 is folded inward, when the projecting piece portion 61 of the support piece 60 is inserted into the insertion hole 35, the projecting piece portion 61. And the insertion hole 35 are engaged, and the position of the support piece 60 is regulated at that position. The same applies to the other support pieces 60.

  If it does in this way, the support piece 60 comes to be each arrange | positioned by the edge part of the depth direction Y in the intermediate part of the width direction X of the box main body 10, and the packing box A of the width direction X is supported by those support pieces 60. The support piece 60 is moved by the engaging action of the projecting piece portion 61 and the insertion hole 35 together with the fact that the load resistance of the packing box A is increased by being reinforced at the end portion in the depth direction Y at the intermediate portion. Therefore, when the load capacity of the packaging box needs to be increased, it is possible to reliably meet the demand. The insertion hole 35 is closed by the outer flaps 32 and 33.

  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 lined up 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.

  The reason why the support piece 60 is provided on the inner flaps 21 and 22 is that the opening S (see FIG. 2) remaining on the folding trace of the support piece 60 is covered with the outer flaps 23 and 24 and is not visible. This is because the opening S is closed by 24 to prevent entry of dust or the like.

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.
