Description

本発明は、物品と包装箱との間または隣接配置する物品間に配置する緩衝材に関する。 The present invention relates to a cushioning material disposed between an article and a packaging box or between adjacently arranged articles.

特許文献１には、正方形状をなす端板と多数の重畳板とが所定の配列で連設された緩衝材が記載されている。この緩衝材は、端板上に各重畳板を順次折り重ねることにより積層構造をなすように形成される。各重畳板には、円形状の貫通孔、円弧状の切り欠き等の位置決め構造が設けられている。 Patent Document 1 describes a cushioning material in which a square end plate and a large number of overlapping plates are arranged in a predetermined arrangement. This buffer material is formed so as to form a laminated structure by sequentially folding each overlapping plate on the end plate. Each overlapping plate is provided with a positioning structure such as a circular through hole and an arcuate cutout.

また、特許文献２には、展開状態で長方形状をなし、対向した一対の長辺にかけて傾斜して延びる折曲線を設けた緩衝材が記載されている。この緩衝材は、折曲線に沿って順次折り曲げることにより、直角三角形状をなす各重畳板が螺旋状をなすように連続し、平面視矩形状をなすように形成される。 Patent Document 2 describes a cushioning material that has a rectangular shape in an unfolded state and is provided with a folding line that extends in an inclined manner toward a pair of opposed long sides. The cushioning material is formed so as to form a rectangular shape in plan view by continuously folding the buffer plates in a right triangle shape along a folding line so as to form a spiral shape.

しかしながら、これらの緩衝材は、多数の重畳板を折り重ねるように順番に積層する必要があるため、組立作業性が悪いという問題がある。しかも、特許文献１の緩衝材は各重畳板間に打抜部が形成されているため、また、特許文献２の緩衝材は積層数が増えると長尺になるため、打ち抜いたブランク状態で納品することができない。 However, since these cushioning materials need to be stacked in order so as to fold a large number of overlapping plates, there is a problem that assembly workability is poor. Moreover, since the cushioning material of Patent Document 1 has punched portions formed between the overlapping plates, and the cushioning material of Patent Document 2 becomes longer as the number of layers increases, it is delivered in a blanked state. Can not do it.

本発明は、ブランクのまま納品が可能で、かつ、簡単に組み立てることが可能な緩衝材を提供することを課題とする。 This invention makes it a subject to provide the shock absorbing material which can be delivered with a blank and can be assembled easily.

前記課題を解決するため、本発明の緩衝材は、表ライナと裏ライナとの間に中しんを配設した段ボール紙製の緩衝材であって、交差するように第１および第２屈曲用罫線を設けるとともに、これら第１および第２屈曲用罫線の交点を通過するように第３屈曲用罫線を設け、前記第１屈曲用罫線と前記第２屈曲用罫線とで、第１および第２板部を区画するとともに、前記第３屈曲用罫線と前記第１および第２屈曲用罫線とで、前記第１板部に連続する一対の第３板部、および、前記第２板部に連続する一対の第４板部を区画し、前記第１および第２屈曲用罫線を山折りするとともに、前記第３屈曲用罫線を谷折りすることで、前記第１および第２板部の間に前記第３および第４板部を折り込んで積層可能であり、展開状態で前記第３屈曲用罫線に、一方の第３板部から隣接する一方の第４板部へ突出する第１の突片部を形成するための第１の迂回部を設けるとともに、他方の第４板部から隣接する他方の第３板部へ突出する第２の突片部を形成するための第２の迂回部を設け、組立状態で、隣接する前記他方の第３板部に前記一方の第３板部の前記第１の突片部を嵌合するとともに、隣接する前記一方の第４板部に前記他方の第４板部の前記第２の突片部を嵌合するようにしている。なお、前記第１屈曲用罫線は縦方向の両端縁（一端縁から他端縁）にかけて延び、前記第２屈曲用罫線は前記第１屈曲用罫線に直交する横方向の両端縁にかけて延び、前記第３屈曲用罫線は前記第１および第２屈曲用罫線に対して４５度の傾斜角度で両端縁にかけて延びる。 In order to solve the above-mentioned problems, the cushioning material of the present invention is a cushioning material made of corrugated paper in which a central shin is disposed between the front liner and the back liner, and is used for the first and second bending so as to intersect. A ruled line is provided, a third bent ruled line is provided so as to pass through the intersection of the first and second bent ruled lines, and the first and second bent ruled lines are the first and second bent ruled lines. A plate part is partitioned, and the third bending ruled line and the first and second bending ruled lines are connected to the pair of third plate parts that are continuous to the first plate part, and to the second plate part. fourth plate portions of the pair defines a to, as well as mountain fold the first and second bending ruled line, said third bending ruled line by a valley fold, between the first and second plate portions is stackable by folding said third and fourth plate portion, the third bending ruled line in the deployed state , Providing a first detour portion for forming a first protruding piece portion projecting from one third plate portion to one adjacent fourth plate portion, and the other adjacent to the other fourth plate portion A second bypass portion is provided for forming a second projecting piece portion projecting to the third plate portion. In the assembled state, the other third plate portion is adjacent to the other third plate portion. In addition to fitting one protruding piece portion, the second protruding piece portion of the other fourth plate portion is fitted to the one adjacent fourth plate portion . The first bending ruled line extends from both longitudinal edges (from one edge to the other edge), and the second bending ruled line extends from both lateral edges perpendicular to the first bending ruled line, The third bending ruled line extends toward both end edges at an inclination angle of 45 degrees with respect to the first and second bending ruled lines.

この緩衝材は、例えば対角に位置する第１および第２板部を把持し、互いに重なり合うように折り曲げる。これにより、第３屈曲用罫線に沿って第３および第４板部が重なり合うように屈曲しながら、第１板部に対して第３板部が屈曲し、第２板部に対して第４板部が屈曲する。そして、組立状態では、第１板部に対して一対の第３板部が横に並んで重なり、また、第２板部に対して一対の第４板部が横に並んで重なり、更に各第３板部に各第４板部が重なる。このように、ワンアクションで４層構造の緩衝材を組み立てることができる。また、緩衝材のブランクは、屈曲用罫線を介して各板部を連設した形状であるため、実質的に正方形状のブランクのまま納品することができる。よって、大幅にコストダウンを図ることができる。 For example, the cushioning material grips the first and second plate portions located diagonally and bends them so as to overlap each other. Accordingly, the third plate portion is bent with respect to the first plate portion while being bent so that the third and fourth plate portions are overlapped along the third bending ruled line, and the fourth plate portion is bent with respect to the second plate portion. The plate is bent. In the assembled state, the pair of third plate portions overlaps the first plate portion side by side, and the pair of fourth plate portions overlaps the second plate portion side by side. Each fourth plate portion overlaps the third plate portion. Thus, a four-layer structure cushioning material can be assembled in one action. In addition, since the blank of the cushioning material has a shape in which each plate portion is continuously provided via a bending ruled line, it can be delivered as a substantially square blank. Therefore, the cost can be greatly reduced.

また、この緩衝材によれば、一方の第３板部に形成した第１の突片部が他方の第３板部に嵌合し、他方の第４板部に形成した第２の突片部が一方の第３板部に嵌合するようにしている。よって、組立状態で第３および第４板部の位置ズレを防止できる。 Moreover, according to this buffer material, the 1st protrusion piece part formed in one 3rd board part fits the other 3rd board part, and the 2nd protrusion piece formed in the other 4th board part The portion is fitted to one third plate portion. Therefore, it is possible to prevent displacement of the third and fourth plate portions in the assembled state .

また、前記第３屈曲用罫線上に位置するように、展開状態で隣接する前記第３および第４板部に保持穴部を設けるとともに、前記迂回部を前記中しんの延び方向に対して平行または直交方向に延びて前記保持穴部に交わるようにする。このようにすれば、第１および第２板部間に形成される保持穴部内に薄板状の物品を収容して保護できる。また、緩衝材の強度劣化を防ぎ、確実に物品を保持することができる。即ち、中しんに対して傾斜して延びる罫線を設けた場合には、耐圧強度が著しく低下するが、傾斜して延びる屈曲用罫線に、中しんに対して平行または直交方向に迂回部を設けているため、強度の低下を防止できる。 In addition, holding holes are provided in the third and fourth plate portions adjacent to each other in the unfolded state so as to be positioned on the third bending ruled line, and the bypass portion is parallel to the extending direction of the central shin. Alternatively, it extends in the orthogonal direction and intersects the holding hole. If it does in this way, a thin plate-shaped article | item can be accommodated and protected in the holding hole part formed between the 1st and 2nd board part. Further, the strength of the cushioning material can be prevented from being deteriorated, and the article can be reliably held. In other words, when a ruled line that extends at an angle with respect to the center shin is provided, the pressure resistance is significantly reduced, but a detour portion is provided on the bending rule line extending at an angle in a direction parallel or perpendicular to the center shin. Therefore, a decrease in strength can be prevented.

さらに、前記第１および第２板部に、組立状態で前記保持穴部に一致する貫通穴部を更に設ける。このようにすれば、貫通穴部および保持穴部を通して所定の物品の一部を挿通できる。例えば、一対の緩衝材を用い、ロール状に巻いた物品の軸の両端を保持させ、包装箱内に収容保持させることができる。 Further, the first and second plate portions are further provided with through-hole portions that match the holding hole portions in the assembled state. In this way, a part of a predetermined article can be inserted through the through hole and the holding hole. For example, using a pair of cushioning materials, both ends of the shaft of the article wound in a roll shape can be held and accommodated and held in the packaging box.

本発明の緩衝材は、第１および第２板部が重なり合うように折り曲げるだけで、４層構造をなすように組み立てることができる。よって、組立作業性を大幅に向上できる。また、緩衝材のブランクは実質的に正方形状であるため、ブランクのまま納品することができる。よって、大幅にコストダウンを図ることができる。 The shock-absorbing material of the present invention can be assembled so as to form a four-layer structure by simply bending the first and second plate portions so as to overlap each other. Therefore, assembly workability can be greatly improved. Moreover, since the blank of a shock absorbing material is substantially square shape, it can be delivered with a blank. Therefore, the cost can be greatly reduced.

Furthermore, the shape of the holding hole 44 and the through hole 45 is not limited to a circular shape or a U-shape, and can be changed as desired, such as a square shape. Furthermore, in the above-described embodiment, the cushioning material 30 is formed by the double-sided cardboard paper 10B, but may be formed by a general-purpose cardboard paper 10A shown in FIG. And in the said embodiment, although the 1st and 2nd bending ruled lines 31 and 32 were comprised by the continuous part 33 and the cutting part 34, and the 3rd bending ruled line 35 was comprised by the half cut line, it is a general purpose folding line The ruled line structure can be changed as desired. Moreover, in the above-described embodiment, the first to third bending ruled lines 31, 32, and 35 are provided so as to extend toward both end edges in the unfolded state. However, they may be provided so as to extend near the end edges. As long as it is provided so as to extend substantially over both ends of the edge.

また、前記実施形態では、組立状態で４層構造をなすように緩衝材３０を構成したが、その積層数も希望に応じて変更が可能である。例えば、図６において、係止舌片部４１を設けていない下側縁を中心として線対称のブランクを形成する。隣接する第４板部４０Ｂ，４０Ｂの境界部分は切断し、隣接する第２板部３８，３８の境界部分には第１屈曲用罫線３１または第３屈曲用罫線３５と同様の屈曲用罫線を形成する。そして、前記と同様にして各ユニットを組み立てた後、表ライナ１１の側で重なり合うように屈曲させることにより、８層構造の緩衝材３０を形成できる。 Moreover, in the said embodiment, although the buffer material 30 was comprised so that a 4-layer structure might be made in an assembly state, the number of lamination | stacking can also be changed as desired. For example, in FIG. 6, a line-symmetric blank is formed around the lower edge where the locking tongue piece 41 is not provided. The boundary portions of the adjacent fourth plate portions 40B and 40B are cut, and the same bending ruled lines as the first bending ruled lines 31 or the third bending ruled lines 35 are formed on the boundary portions of the adjacent second plate portions 38 and 38. Form. Then, after assembling the units in the same manner as described above, the cushioning material 30 having an eight-layer structure can be formed by bending the units so as to overlap each other on the front liner 11 side.
