Description

本発明は、樹脂段ボール板、樹脂板を使用した組立て箱に関する。 The present invention relates to a resin corrugated board and an assembly box using the resin board.

従来、例えば特許文献1に示す組立て箱は、一定方向にリブ又は一定方向に配列する略円柱形状のリブを有するよう一体に成形されたプラスチック段ボールから構成される底板、複数の側板を有する筐体の互いに隣接する複数の側板における上端縁の角部に固定され、該上端縁の上面に重層する上端面及び当該上端面から上方に延設され、上方へ載置される収納箱を安定して保持する保持片を有する角部材と、複数の側板の上端縁に着脱可能に取り付けられ、角部材における上端面及び保持片と略同一平面を形成する上端面及び保持片を有して、断面を略ｈ形状に成形し下方に位置する一端部に係合部を有する縁部材とからなり、角部材は、上端面と対向する下端面にＬ形凹部を有して略Ｌ字状に形成される基体の両端部から突出し、下端面に凹部を有した突状部を備え、角部材のＬ形凹部を互いに隣接する複数の側板端部に嵌合し、側板の端部に連設した第１スリットを一端部に有し、他端部に第２スリットを有する凸状片に角部材における凹部を嵌合して取り付け、角部材の突状部に縁部材を覆設して取り付け、筐体における複数の側板に設けた抜け防止部材に縁部材における係合部を係止して組立て可能にした構造からなる。 2. Description of the Related Art Conventionally, for example, an assembly box shown in Patent Document 1, for example, has a bottom plate composed of plastic corrugated cardboard integrally formed so as to have ribs in a certain direction or substantially cylindrical ribs arranged in a certain direction, and a housing having a plurality of side plates. The upper end surface of the plurality of side plates adjacent to each other is fixed to the corner of the upper end edge, the upper end surface overlapping the upper surface of the upper end edge, and extending upward from the upper end surface to stably hold the storage box placed upward A corner member having a holding piece to hold, and an upper end surface and a holding piece that are detachably attached to the upper end edges of the plurality of side plates and form a substantially same plane as the upper end surface and the holding piece in the corner member, The corner member is formed in a substantially L shape with an L-shaped recess on the lower end surface facing the upper end surface. Protruding from both ends of the base A projecting portion having a concave portion, the L-shaped concave portion of the square member is fitted to a plurality of side plate end portions adjacent to each other, and a first slit continuously provided at the end portion of the side plate is provided at one end portion; The concave member in the corner member is fitted and attached to the convex piece having the second slit in the portion, the edge member is covered and attached to the convex portion of the corner member, and the slip prevention member provided on the plurality of side plates in the casing The engaging portion of the edge member is locked and assembled.

上記組立て箱は、角部材の基体に対して長側板及び短側板の各上端部に挿嵌して固定する構造であるため、角部材による長側板及び短側板の連結強度は、これらに対する角部材の嵌め込み強度に大きく依存している。このため、取り扱い時に作用する外力により長側板及び短側板から角部材が外れて連結不能になり易く、長期にわたって箱型を確実に保つことが困難になる問題を有している。また、長側板及び短側板から角部材が外れた際には、収容物が飛び出し易くなり、収容物を安全に収容できない恐れがある。 Since the assembly box has a structure in which the upper end portion of the long side plate and the short side plate is inserted and fixed to the base of the square member, the connection strength of the long side plate and the short side plate by the square member is the square member with respect to them. It largely depends on the fitting strength. For this reason, there is a problem that the square member is easily detached from the long side plate and the short side plate due to an external force acting at the time of handling and cannot be connected, and it is difficult to reliably maintain the box shape for a long time. In addition, when the corner member is detached from the long side plate and the short side plate, the stored item easily jumps out, and the stored item may not be stored safely.

また、組立て箱を組立てる際には、起立した長側板の端部に形成された第１及び第２切欠きと該端部の内面に重ね合わされた起立した短側板の重合片に形成された第１及び第２切欠きをそれぞれ一致させて第１及び第２スリットを形成する必要があり、それぞれの切欠きの位置合わせ作業に手間がかかり、組み立て作業性が悪い問題を有している。 Further, when assembling the assembly box, the first and second notches formed at the end portion of the standing long side plate and the overlapping piece of the standing short side plate superimposed on the inner surface of the end portion are formed. It is necessary to form the first and second slits by making the first and second cutouts coincide with each other, and it takes time to align the cutouts, resulting in poor assembly workability.

更に、角部材の突状部に挿嵌した状態で側板の上部に取付けられる縁部材にあっては、側板の上部から外れるのを防止するため、側板の上部に抜け防止部材を設け、縁部材の係合部を係止している。このため、側板の上部に抜け防止部材を取付ける必要があり、そのための加工に手間がかかり、製造コストが増大する問題を有している。特に、プラスチック段ボール自体、押出し成形により製造されるため、プラスチック段ボールに抜け防止部材を固着するには、接着剤で接着したり、超音波等で溶着する必要があり、固着作業に手間がかかっていた。 Further, in the edge member attached to the upper part of the side plate in a state of being inserted into the protruding portion of the corner member, in order to prevent the edge member from coming off from the upper part of the side plate, an anti-slip member is provided at the upper part of the side plate. The engaging part is locked. For this reason, it is necessary to attach a slip-off preventing member to the upper part of the side plate, and there is a problem that it takes time and effort to increase the manufacturing cost. In particular, the plastic corrugated board itself is manufactured by extrusion molding. Therefore, in order to fix the slip-off preventing member to the plastic corrugated board, it is necessary to bond it with an adhesive or to weld it with ultrasonic waves or the like. It was.

解決しようとする問題点は、角部材による側板の連結強度が期待の空間部に対する側板の嵌め込み強度に依存するため、充分な連結強度を得ることが困難で、長期にわたって箱状態を確実に保つことができない恐れがあり、収容物を安全に収容することができない恐れがある点にある。 The problem to be solved is that the connection strength of the side plate by the square member depends on the fitting strength of the side plate to the expected space, so it is difficult to obtain sufficient connection strength, and the box state is reliably maintained for a long time This is because there is a possibility that the contents cannot be stored safely.

また、長側板及び短側板に対して角部材を挿嵌して固定するため、突状部の空間部に対して第１及び第２スリットを位置合わせする作業に手間がかかり、組み立て作業性が悪い点にある。 In addition, since the square member is inserted and fixed to the long side plate and the short side plate, the work of aligning the first and second slits with respect to the space portion of the projecting portion takes time and the assembly workability is improved. There is a bad point.

更に、側板に対する突状部の挿嵌状態を保つには、側板の上部に、突状部及び側板の上部に嵌め込まれる縁部材の係合部が係止する抜け防止部材を設ける必要があるが、側板に抜け防止部材を設けるのに手間がかかり、加工工程数が増大して製造コストが増大する点にある。 Furthermore, in order to maintain the insertion state of the protruding portion with respect to the side plate, it is necessary to provide an anti-disengagement member that is engaged with the engaging portion of the edge member that is fitted into the upper portion of the protruding portion and the side plate. In addition, it takes time to provide the side plate with the slip prevention member, which increases the number of processing steps and increases the manufacturing cost.

本発明は、底板の相対する一方側縁に一体形成され、起立する一対の長側板及び底板の相対する他方側縁に一体形成され、起立する一対の短側板の各端側上部をコーナ部材により直角状にそれぞれ連結して箱型に組立てられる組立て箱において、各コーナ部材は、長側板の端側上部に挿嵌される第１嵌合基体部及び短側板の端側上部に嵌合される第２嵌合基体部を直角状で一体形成し、第１嵌合基体部から長側板の少なくとも上面を覆うように延出する第１突出部に、長側板の一方側面に沿って屈曲可能で、長側板に形成された係止孔内へ挿入可能な第１突入部を有した第１屈曲板を一体形成し、第２嵌合基体部から短側板の少なくとも上面を覆うように延出する第２突出部に、短側板の一方側面に沿って屈曲可能で、短側板に形成された係止孔内へ挿入可能な第２突入部を有した第２屈曲板を一体形成した構成からなると共に、長側板及び短側板を直角状に連結する各コーナ部材の対向する各第１突出部及び第１屈曲板に対して両端部がそれぞれ挿嵌され、長側板の上端面及び上部内外側面を覆う第１上フレーム及び各コーナ部材の対向する各第２突出部及び第２屈曲板に対して両端部がそれぞれ挿嵌されて短側板の上端面及び上部内外側面を覆う第２上フレームを設け、第１上フレームにより長側板の係止孔に対する第１突入部の挿入状態及び第２上フレームにより短側板の係止孔に対する第２突入部の挿入状態をそれぞれ保持可能にすることを最も主要な特徴とする。 In the present invention, a pair of long side plates that are integrally formed on the opposite one side edge of the bottom plate and a pair of short side plates that are integrally formed on the other opposite side edge of the bottom plate and the upper ends of the pair of short side plates are In an assembly box that is connected to each other at right angles and assembled into a box shape, each corner member is fitted to a first fitting base portion that is fitted to the upper end portion of the long side plate and an upper end portion of the short side plate. The second fitting base portion is integrally formed at a right angle, and can be bent along one side surface of the long side plate to the first projecting portion extending from the first fitting base portion so as to cover at least the upper surface of the long side plate. A first bent plate having a first protrusion that can be inserted into a locking hole formed in the long side plate is integrally formed, and extends from the second fitting base portion so as to cover at least the upper surface of the short side plate. The second projecting portion can be bent along one side surface of the short side plate and is formed on the short side plate. The second bent plate having a second inrush portion insertable into the hole with consisting integrally formed with the structure, the first protrusion each opposing each corner member for connecting the long side plates and short side plate at a right angle shape and the Both ends are inserted into one bent plate, both ends of the first upper frame covering the upper end surface and the upper inner and outer surfaces of the long side plate and the second projecting portions and the second bent plate facing each corner member. The second upper frame is provided to cover the upper end surface and the upper inner and outer surfaces of the short side plate with the respective parts inserted and inserted, and the first upper frame inserts the first protrusion into the locking hole of the long side plate and the second upper frame. The main feature is that each of the insertion states of the second protrusions with respect to the locking holes of the short side plate can be held .

本発明は、長側板及び短側板に対してコーナ部材を強固に固定して連結状態を保つことができ、長期にわたって安定的に箱型を維持して収容物を安全に収容することができる。また、組み立て作業時には、側板に対して角部材を簡易に固定することができ、組立て作業を簡易化することができる。更に、側板の上部に特別の加工を施す必要がなく、側板の加工工程が増大するのを回避して製造コストを低減することができる。 According to the present invention, the corner member can be firmly fixed to the long side plate and the short side plate to maintain the connected state, and the box shape can be stably maintained over a long period of time, and the contents can be safely stored. Further, at the time of assembling work, the square member can be easily fixed to the side plate, and the assembling work can be simplified. Furthermore, it is not necessary to perform special processing on the upper portion of the side plate, and the manufacturing cost can be reduced by avoiding an increase in the side plate processing steps.

When the plurality of assembly boxes 1 are stacked in multiple stages, these locking walls 11b and 13b engage with the lower part of the assembly box 1 located above to prevent the positional displacement of each assembly box 1.

次に、上記構造からなる組立て箱１の組立て作用を説明する。
先ず、箱板材３の底板１５に対して一対の長側板７をそれぞれ起立させた状態で各両側の重合板１７を内側へ折り返した後、上記状態にて一対の短側板９をそれぞれ起立させて重合板１７に重ね合わせる。この状態において短側板９における第３長孔９ａと重合板１７の第２長孔１７ａは、互いに一致して連通している。（図１参照） Next, the assembly operation of the assembly box 1 having the above structure will be described.
First, after the pair of long side plates 7 are erected with respect to the bottom plate 15 of the box plate material 3, the overlapping plates 17 on both sides are folded inward, and then the pair of short side plates 9 are erected in the above state. Superimpose on the polymerization plate 17. In this state, the third long hole 9a in the short side plate 9 and the second long hole 17a in the overlapping plate 17 are in communication with each other. (See Figure 1)

なお、重合板１７に短側板９を重ね合わせた際に、該重合板１７の切欠き部１７ｂと短側板９の取付け孔９ｂとは一致して開口を形成している。そして切欠き部１７ｂに応じた重合板１７の内面に手掛け内板３１を配置した状態で短側板９の外側から手掛け外板３３を取付け孔９ｂ及び切欠き部１７ｂ内に挿入して掛け止めすることにより短側板７と重合板１７を固定させる。重ね合わされた短側板９及び重合板１７に対する手掛け内板３１及び手掛け外板３３の取付けは、組立て箱１の組立て完了後であってもよい。 When the short side plate 9 is superimposed on the superposed plate 17, the notch portion 17b of the superposed plate 17 and the mounting hole 9b of the short side plate 9 coincide with each other to form an opening. Then, with the handle inner plate 31 arranged on the inner surface of the overlapping plate 17 corresponding to the notch 17b, the handle outer plate 33 is inserted from the outer side of the short side plate 9 into the mounting hole 9b and the notch 17b and latched. As a result, the short side plate 7 and the superposed plate 17 are fixed. The attachment of the handle inner plate 31 and the handle outer plate 33 to the superposed short side plate 9 and superposed plate 17 may be after the assembly of the assembly box 1 is completed.

次に、上記状態にて長側板７と重ね合わされた短側板９及び重合板１７の角部に対してコーナ部材５を、第１嵌合基体部５ａが長側板７の上端部に、また第２嵌合基体部５ｂが重ね合わされた短側板９及び重合板１７の上端部にそれぞれ嵌め込んで取付ける。このとき、第１突出部５ｃは、長側板７の上端面及び上部内面を覆い、かつ第１屈曲板１９は、ほぼ水平状態になっている。また、第２突出部５ｄは、重ね合わされた短側板及び重合板１７の上端面及び重合板１７の上部内面を覆い、かつ第２屈曲板２１は、ほぼ水平状態になっている。（図７参照） Next, in the above state, the corner member 5 is placed on the corners of the short side plate 9 and the superposed plate 17 overlapped with the long side plate 7, the first fitting base portion 5 a is on the upper end portion of the long side plate 7, 2 The fitting base portion 5b is fitted and attached to the upper end portions of the short side plate 9 and the superposed plate 17 which are overlapped. At this time, the 1st protrusion part 5c covers the upper end surface and upper inner surface of the long side board 7, and the 1st bending board 19 is a substantially horizontal state. The second projecting portion 5d covers the short side plate and the upper end surface of the superposed plate 17 and the upper inner surface of the superposed plate 17, and the second bent plate 21 is in a substantially horizontal state.
