Description

本発明は、主に野菜や果物等の梱包に使用される組立式箱に関する。 The present invention relates to a prefabricated box mainly used for packing vegetables and fruits.

従来、一枚の段ボール製板材を所定の形状、即ち箱を展開した状態に打ち抜き、それを折曲加工することにより、平板状の底板と、底板の四辺に折り目を介して一体に形成された前側板、背側板、左側板及び右側板とからなる箱状に組立てられる組立式箱が広く使用されている。 Conventionally, a sheet of corrugated board is punched into a predetermined shape, that is, a state in which the box is unfolded, and is bent so that it is integrally formed with a flat bottom plate and four sides of the bottom plate through creases. 2. Description of the Related Art An assembly box that is assembled in a box shape including a front side plate, a back side plate, a left side plate, and a right side plate is widely used.

しかし、このような組立式箱は、一枚の段ボール製板材から構成されているという性質上、例えば、前側板及び背側板の段目方向が縦向きである場合には、左右側板の段目方向が横向きとなるように、互いに直交配置にある側板同士で段ボールの段目の方向が異なる。 However, such an assembly-type box is composed of a single corrugated board material. For example, when the step direction of the front side plate and the back side plate is vertical, the step of the left and right side plates is performed. The direction of the corrugated board is different between the side plates that are orthogonal to each other so that the direction is horizontal.

従って、このような組立式箱を多段積みするなどして、箱に上方からの荷重が作用した場合、段目方向が縦向きの側板は十分な強度を有するが、段目方向が横向きの側板では強度が不足して座屈しやすいという問題があった。 Therefore, when a load from above is applied to the box, for example, by stacking such assembling boxes, the side plate in which the step direction is vertical has sufficient strength, but the side plate in which the step direction is horizontal. However, there was a problem that the strength was insufficient and it was easy to buckle.

そこで、段目が縦向きの側板を、底板と折り目を介して連続した外側板と、外側板と一定幅を有する上縁板を介して一体に形成された内側板とをもって構成するとともに、内側板の両側縁に折り目を介して一体に形成された補強板を備え、底板に対し各側板を立ち上げて箱状に組立てた際に、前記補強板を段目が横向きの側板の内側に折り込み補強することができる組立式箱が開発されている（例えば、特許文献１を参照）。
特開２００２−３３２０２６号公報 Therefore, the side plate having the vertical stage is constituted by an outer plate that is continuous through the bottom plate and the fold, and an inner plate that is formed integrally with the outer plate and the upper edge plate having a certain width. Reinforcing plates integrally formed through folds on both side edges of the plate, and when the side plates are raised from the bottom plate and assembled into a box shape, the reinforcing plate is folded inside the side plate with the stepwise sideways An assembly box that can be reinforced has been developed (see, for example, Patent Document 1).

次に、上述した組立式箱１０の組立方法を説明する。 Next, a method for assembling the assembly box 10 described above will be described.

まず、図４（ａ）〜（ｂ）に示すように、左右両側板１８，１９を折り目１４，１５より内側、即ち底板１１側に折り曲げ、左右両側板１８，１９の底板１１とは反対側の縁部より連接された左右両頂板２６，２７及び押さえ板５２，５２とともに底板１１に重ねて折り畳む。そして、そのとき一緒に折られる各連結板２０，２１，２２，２３の固定部５６を前外側板２８及び背外側板３１の重なり合った部分に接着剤等によって貼着させる。 First, as shown in FIGS. 4A to 4B, the left and right side plates 18 and 19 are folded inward from the folds 14 and 15, that is, the bottom plate 11 side, and the left and right side plates 18 and 19 are opposite to the bottom plate 11. The left and right top plates 26 and 27 and the presser plates 52 and 52 connected to each other from the edge of the bottom plate 11 are overlapped and folded. Then, the fixing portions 56 of the connecting plates 20, 21, 22, 23 that are folded together at that time are attached to the overlapping portions of the front outer plate 28 and the back outer plate 31 with an adhesive or the like.

このように各連結板２０，２１，２２，２３の固定部５６を前外側板２８及び背外側板３１の重なり合った部分に貼着させたことにより、前側板１６及び背側板１７を立ち上げると貼着された各連結板２０，２１，２２，２３に連動して左右両側板１８，１９も立ち上がるようになっている。 When the front plate 16 and the back plate 17 are started up by sticking the fixing portions 56 of the connecting plates 20, 21, 22, and 23 to the overlapping portions of the front outer plate 28 and the back outer plate 31 in this way. The left and right side plates 18, 19 are also raised in conjunction with the attached connecting plates 20, 21, 22, 23.

次に、図４（ｂ）〜（ｃ）に示すように、前背両内側板３０，３３を上縁板２９，３２の両縁部を折り目として内側に折り曲げ、前背両外側板２８，３１に重ね合わせ、重なり合った内側板３０，３３を外側板２８，３１の内側面に貼着させ、前背両側板１６，１７を形成する。 Next, as shown in FIGS. 4B to 4C, the front inner and rear inner plates 30, 33 are folded inward with both edge portions of the upper edge plates 29, 32 as folds, and the front and rear outer plates 28, The inner side plates 30 and 33 overlapped with each other are attached to the inner side surfaces of the outer side plates 28 and 31 to form the front and back side plates 16 and 17.

このとき、前内側板３０及び背内側板３３に形成された回避用凹部３４により、左右両頂板２６，２７の側縁に形成された係止片４８は、内側板３０，３３により押さえ込まれないようになっている。 At this time, due to the avoidance recesses 34 formed in the front inner plate 30 and the back inner plate 33, the locking pieces 48 formed on the side edges of the left and right top plates 26, 27 are not pressed by the inner plates 30, 33. It is like that.

また、前背両内側板３０，３３を上縁板２９，３２を介して折り曲げることにより、前背両上縁板２９，３２よりガイド片５０が立ち上がるとともに、係止孔４９が形成される。 Further, by bending the front and rear inner plates 30 and 33 through the upper edge plates 29 and 32, the guide piece 50 rises from the front and rear upper edge plates 29 and 32, and a locking hole 49 is formed.

そして、図４（ｃ）〜（ｄ）に示すように、各補強板４０を折り目３９より折り曲げて前背両内側板３０，３３にそれぞれ重ね合わせ、仮止め手段、即ち、補強板４０の切り起し片４６を前背両内側板３０，３３の係止用孔４５に係合させて補強板４０を前背両内側板３０，３３に仮止めする。 Then, as shown in FIGS. 4C to 4D, the reinforcing plates 40 are folded from the crease 39 and overlapped with the front and back inner plates 30, 33, respectively, and the temporary fixing means, that is, the cutting of the reinforcing plate 40 is performed. The reinforcing piece 40 is temporarily fixed to the front and back inner plates 30 and 33 by engaging the raised pieces 46 with the locking holes 45 of the front and rear inner plates 30 and 33.

これで一次組立が終了し、組立中間部材６０が形成され、この状態で、運搬や保管等を行えば、平板状であるので重ねても嵩張らず効率がよい。 In this state, the primary assembly is completed, and the intermediate assembly member 60 is formed. In this state, if transportation, storage, or the like is performed, the plate is in a flat shape and is efficient without being bulky.

次に、この組立中間部材６０を図４（ｄ）〜図５（ｅ）に示すように、左右両頂板２６，２７及び押さえ板５２，２５がそれぞれ一体に形成された左側板１８及び右側板１９を立ち上げると、各連結板２０，２１，２２，２３が連動して、前側板１６及び背側板１７も立ち上がる。このとき逃がし片部３６が立ち上がることにより、各連結板２０，２１，２２，２３が前背両内側板３０，３３に邪魔されずに好適に作動する。 Next, as shown in FIGS. 4 (d) to 5 (e), the left-side plate 18 and the right-side plate in which the left and right top plates 26 and 27 and the pressing plates 52 and 25 are integrally formed are assembled into the assembly intermediate member 60. When 19 is raised, the connecting plates 20, 21, 22, 23 are interlocked, and the front side plate 16 and the back side plate 17 are also raised. At this time, when the escape piece 36 rises, the connecting plates 20, 21, 22, and 23 are preferably operated without being obstructed by the front and rear inner plates 30 and 33.

また、補強板４０が折り目３５を跨いで配置されているので、折り目３５より折曲がり内側板３０，３３に対して逃がし片部３６が立ち上がると、図６に示すように、逃がし片部３６と補強板４０との間が離間し、それにより仮止め手段が自動的に解除され、即ち、補強板４０の切り起し片４６が逃がし片部３６の係止用孔４５より外れ、補強板４０が前背両内側板３０，３３より離脱して段ボール板材の弾性力により立ち上がるようになっている。 Further, since the reinforcing plate 40 is disposed across the crease 35, when the escape piece 36 rises with respect to the inner plates 30, 33 by bending from the crease 35, as shown in FIG. 6, The temporary fixing means is automatically released due to the separation from the reinforcing plate 40, that is, the cut-and-raised piece 46 of the reinforcing plate 40 comes out of the locking hole 45 of the escape piece 36, and the reinforcing plate 40 is released. Is separated from the front and rear inner plates 30, 33 and rises due to the elastic force of the corrugated board material.

そして、図５（ｅ）〜（ｆ）に示すように、各側板１６，１７，１８，１９を底板１１に対して立ち上げ、逃がし片部３６を元に戻して、前内側板３０及び背内側板３３の係合突起を底板１１、左側板１８及び右側板１９の各係止孔に係合させ、各連結板２０，２１，２２，２３の固定部５６と可動部５７とが重なり合った部分を、前外側板２８と前内側板３０との間、或いは背外側板３１と背内側板３３との間で挟持する。 Then, as shown in FIGS. 5E to 5F, the side plates 16, 17, 18, 19 are raised with respect to the bottom plate 11, the escape piece 36 is returned to the original position, and the front inner plate 30 and the back plate are restored. The engaging projections of the inner plate 33 are engaged with the respective locking holes of the bottom plate 11, the left side plate 18, and the right side plate 19, and the fixed portion 56 and the movable portion 57 of each connecting plate 20, 21, 22, 23 overlap each other. The portion is sandwiched between the front outer plate 28 and the front inner plate 30 or between the back outer plate 31 and the back inner plate 33.

また、各側板１６，１７，１８，１９を底板１１に対し立ち上げることにより、各補強板４０，４０…が左右両側板１８，１９の内側に自動的に配置される。 Further, by raising the side plates 16, 17, 18, 19 with respect to the bottom plate 11, the reinforcing plates 40, 40... Are automatically arranged inside the left and right side plates 18, 19.

最後に、図５（ｆ）〜（ｇ）に示すように、折り目２４，２５より左右両頂板２６，２７を内側へ折り曲げ、両側縁の係止片４８をガイド片５０にガイドさせながら係止孔４９に挿入して係合させ、更に、図５（ｇ）〜（ｈ）に示すように、押さえ板５２，５２を折り目５１より内側に折り曲げ、係止突起５４を係止孔５３に係合させ、左右両側板１８，１９と押さえ板５２との間に補強板４０を挟持する。 Finally, as shown in FIGS. 5 (f) to 5 (g), the left and right top plates 26, 27 are folded inward from the folds 24, 25, and the locking pieces 48 on both side edges are locked while being guided by the guide pieces 50. Further, as shown in FIGS. 5G to 5H, the pressing plates 52 and 52 are bent inward from the fold line 51 and the locking projection 54 is engaged with the locking hole 53 as shown in FIGS. The reinforcing plate 40 is sandwiched between the left and right side plates 18 and 19 and the holding plate 52.

これで、組立式箱１０の組立てが完了する。 This completes the assembly of the assembling box 10.

この組立式箱１０を分解する際には、押さえ板５２を底板１１より取り外すとともに、左右両頂板２６，２７の係止片４８を上縁板より取り外し、逃がし片部３６を立ち上げ、そのまま前側板１６及び背側板１７を寝かせると、各連結板２０，２１，２２，２３に連動して左側板１８及び右側板１９も底板１１に重ねて折り畳んだ状態となり、その状態で、補強板４０を仮止め手段により前背両内側板３０，３３にそれぞれ仮止めすることによって、一次組立が終了したときと同じ状態になる。 When disassembling the assembling box 10, the holding plate 52 is removed from the bottom plate 11, the locking pieces 48 of the left and right top plates 26 and 27 are removed from the upper edge plate, the relief piece 36 is raised, When the side plate 16 and the back side plate 17 are laid down, the left side plate 18 and the right side plate 19 are overlapped with the bottom plate 11 in conjunction with the connecting plates 20, 21, 22, and 23. By temporarily fixing the front and back inner plates 30, 33 by temporary fixing means, the same state as when the primary assembly is completed is obtained.

尚、上述の実施例では、仮止め手段を円形の係止用孔４５と、楕円形の切り起し片４６とをもって構成した例について説明したが、仮止め手段を、図７に示すように、折り目３９側に頂点が配置された三角形状の係止用孔６５と、台形状の切り起し片６６とをもって構成してもよい。尚、上述の実施例と同一の部分には同一符号を付して説明を省略する。 In the above-described embodiment, the example in which the temporary fixing means is constituted by the circular locking hole 45 and the oval cut and raised piece 46 has been described. However, the temporary fixing means is as shown in FIG. Alternatively, a triangular locking hole 65 whose apex is arranged on the crease 39 side and a trapezoidal cut and raised piece 66 may be used. In addition, the same code | symbol is attached | subjected to the part same as the above-mentioned Example, and description is abbreviate | omitted.

この係止用孔６５と切り起し片６６とは、折り目３９より補強板４０を折曲げ、内側板３０，３３に重ね合わせた際に、係止用孔６５の三角形の底辺部と切り起し片６６の台形の底辺部とが略同じ位置に配置されるように、折り目３９を介して略対称な位置に形成されている。 The locking hole 65 and the cut-and-raised piece 66 are formed by cutting and raising the triangular base of the locking hole 65 when the reinforcing plate 40 is bent from the crease 39 and superimposed on the inner plates 30 and 33. The trapezoid 66 is formed at a substantially symmetrical position via the crease 39 so that the bottom of the trapezoid is disposed at substantially the same position.

切り起し片６６は、底辺部に支持部６６ａが一体に形成され、支持部６６ａの一部を残して切れ目を入れることにより補強板４０より立ち上げ可能に形成されている。 The cut-and-raised piece 66 is formed so that it can be raised from the reinforcing plate 40 by integrally forming a support portion 66a on the bottom side, and making a cut while leaving a part of the support portion 66a.

支持部６６ａは、残された部分側が狭いテーパ状に形成されている。 The support portion 66a is formed in a tapered shape with the remaining portion side being narrow.

このように構成された仮止め手段は、折り目３９より折り曲げて補強板４０を内側板３０，３３に重ね合わせた際に、係止用孔６５の三角形の底辺部と切り起し片６６の台形の底辺部とが略同じ位置に配置され、その位置で指等により切り起し片６６を内側板側に押し込むことにより、支持部６６ａを介して台形状の切り起し片６６が立ち上がり、三角形の係止用孔６５に嵌り込んで仮止めされるようになっている。 The temporary fixing means configured as described above is formed in the trapezoidal shape of the triangular base of the locking hole 65 and the trapezoidal piece 66 when the reinforcing plate 40 is overlapped with the inner plates 30 and 33 by bending from the crease 39. Are arranged at substantially the same position, and by cutting and raising with a finger or the like at that position and pushing the piece 66 toward the inner plate, the trapezoidal cut and raised piece 66 rises via the support portion 66a, and the triangle It is inserted into the locking hole 65 and temporarily fixed.

また、図６に示す場合と同様に、内側板３０，３３、即ち逃がし片部３６に補強板４０を仮止めした状態から、逃がし片部３６を立ち上げると、逃がし片部３６と補強板４０との間には互いに離間する方向に力が作用し、支持部６６ａの根元部分、即ち逃がし片部３６と切り起し片６６とを連結している部分にねじれが生じ、それにより切り起し片６６が補強板４０よりねじり切られて仮止めが解除されるようになっている。 Similarly to the case shown in FIG. 6, when the relief piece 36 is raised from the state where the reinforcement plate 40 is temporarily fixed to the inner plates 30, 33, that is, the relief piece 36, the relief piece 36 and the reinforcement plate 40 are raised. A force acts in a direction away from each other, and a torsion occurs in the root portion of the support portion 66a, that is, the portion connecting the relief piece 36 and the cut piece 66, thereby causing the cut. The piece 66 is twisted off from the reinforcing plate 40 so that the temporary fixing is released.

また、上述の実施例では、仮止め手段を係止用孔と切り起し片をもって構成した例について説明したが、仮止め手段は、内側板又は補強板の互いに向い合う面の一方又は両方に粘着性の弱い粘着テープ等の粘着材を貼り付けておくことにより構成してもよく、その他、一定の保持力を有する一方、所定の力で容易に取り外し可能な状態に仮止めできるものであればよい。 Further, in the above-described embodiment, the example in which the temporary fixing means is configured with the locking holes and the cut and raised pieces has been described, but the temporary fixing means is provided on one or both of the inner plate or the reinforcing plate facing each other. It may be configured by sticking adhesive material such as adhesive tape with weak adhesiveness, etc. Other than having a certain holding force, it can be temporarily fixed in a removable state with a predetermined force. That's fine.

尚、上述の実施例では、押さえ板５２を設け、補強板４０を左右側板１８，１９と押さえ板５２との間に挟持するようにした例について説明したが、押さえ板５２は設けずともよい。 In the above-described embodiment, an example in which the pressing plate 52 is provided and the reinforcing plate 40 is sandwiched between the left and right side plates 18 and 19 and the pressing plate 52 has been described, but the pressing plate 52 may not be provided. .
