Description

本発明は、箱内に収容して箱内を格子状に区画する仕切体に関する。 The present invention relates to a partition that is housed in a box and partitions the box in a lattice shape.

一般に、瓶体等の物品を複数配列して箱内に収納するとき、隣り合う物品同士が互いに接触して損傷することのないように、箱内を格子状に区画する仕切体が用いられる。この種の仕切体としては、段ボール板紙によって形成された複数枚の第１仕切板と複数枚の第２仕切板とを互いに交差させて平面視井桁状に組むことによって形成されるものが知られている。しかし、第１仕切板と第２仕切板とを互いに交差させて組立てる仕切体においては、第１仕切板と第２仕切板との相互の組み付け作業が煩わしいだけでなく、組み立てた後に第１仕切板と第２仕切板とが外れやすく、使い勝手が悪い。 In general, when a plurality of articles such as bottles are arranged and stored in a box, a partition body that partitions the inside of the box in a lattice shape is used so that adjacent articles do not come into contact with each other and are damaged. As this kind of partition, what is formed by crossing a plurality of first partition plates and a plurality of second partition plates formed by corrugated paperboard into a plane view girder is known. ing. However, in the partition body assembled by crossing the first partition plate and the second partition plate, not only the assembly work of the first partition plate and the second partition plate is troublesome but also the first partition after assembly. The plate and the second partition plate are easy to come off and the usability is bad.

また、従来、底板の両側端縁に連設された一対の第１仕切板を起立させ、第２仕切板を両第１仕切板に交差するように下方から組み付けた仕切体が知られている（特許文献１参照）。この仕切体によれば、一対の第１仕切板が底板と一体に連設されている分、部品点数を削減することができる。また、特許文献１に記載された仕切体においては、底板と一体の第１仕切板に第２仕切板が下方から組み付けられ、更に、第２仕切板に設けられた突起を第１仕切板の溝部に係合させるので、組み立てた後の第１仕切板と第２仕切板との係合状態が比較的強固に維持されて、不用意な外れを防止することができる。しかし、このように、第１仕切板と第２仕切板とが強固に係合する仕切体は、一旦組み立てられると扁平に折り畳むことができず、未使用状態では嵩張る不都合がある。
実開昭５４−１３０９７８号公報（第１図〜第４図） Further, conventionally, a partition body is known in which a pair of first partition plates that are connected to both side edges of the bottom plate are erected and the second partition plate is assembled from below so as to intersect the first partition plates. (See Patent Document 1). According to this partition, the number of parts can be reduced by the amount of the pair of first partition plates that are integrally provided with the bottom plate. Moreover, in the partition body described in Patent Document 1, the second partition plate is assembled from the lower side to the first partition plate integrated with the bottom plate, and the protrusion provided on the second partition plate is further connected to the first partition plate. Since it is made to engage with a groove part, the engagement state of the 1st partition plate and 2nd partition plate after an assembly is maintained comparatively firmly, and it can prevent careless disconnection. However, the partition body in which the first partition plate and the second partition plate are firmly engaged as described above cannot be folded flat once assembled, and there is a disadvantage that it is bulky when not in use.
Japanese Utility Model Publication No. 54-130978 (FIGS. 1 to 4)

かかる不都合を解消して、本発明は、互いに交差する第１仕切板と第２仕切板との係合状態を確実に維持することができるだけでなく、容易に折り畳むことができ、しかも、折り畳んだ状態から仕切り状態に第１仕切板と第２仕切板とを直交させたとき、第１仕切板と第２仕切板とが直交する仕切り状態を確実に維持することができる仕切体を提供することを目的とする。 In order to eliminate such inconvenience, the present invention can not only reliably maintain the engagement state of the first partition plate and the second partition plate intersecting each other, but also can be easily folded and folded. To provide a partition body that can reliably maintain a partition state in which the first partition plate and the second partition plate are orthogonal when the first partition plate and the second partition plate are orthogonally crossed from the state to the partition state. With the goal.

かかる目的を達成するために、本発明は、矩形状の底板の両側端縁に折目線を介して連設された一対の第１仕切板が互いに対向するように起立され、両第１仕切板に交差する方向に第２仕切板が組み付けられ、該第２仕切板は、底板に形成された底部切込みを介して底板を下方から貫通して、該底部切込みの両端に連続して両第１仕切板の下縁から上方に向かって所定の位置まで延びる下切込みに挿着され、更に、両第１仕切板の各下切込みに対応して形成された前記第２仕切板の上縁から下方に向かって所定の位置まで延びる一対の上切込みに、各第１仕切板の上縁と下切込みの上端との間の板面が挿着されてなる段ボール板紙製の仕切体において、前記底板は、両第１仕切板間の中央に沿って延びる第１折畳線を介して該底板の上面同士が重合する方向に折り畳み自在とされ、前記第２仕切板は、両上切込みの中央に沿って延びる第２折畳線を介して該第２仕切板の一側面同士が重合する方向に折り畳み自在とされ、前記第２仕切板の両上切込みは、互いに第２折畳線を軸とする左右対称に一側方に向かって屈曲又は湾曲する形状に形成されており、各上切込みに挿着された各第１仕切板は、各上切込みに沿って湾曲して弾発的に該上切込みに圧接係合することを特徴とする。 In order to achieve such an object, the present invention is such that a pair of first partition plates connected to both side edges of a rectangular bottom plate via a crease line are erected so as to face each other. The second partition plate is assembled in a direction crossing the bottom plate, and the second partition plate passes through the bottom plate from below through a bottom notch formed in the bottom plate, and is continuously connected to both ends of the bottom notch. Inserted into a lower notch extending upward from the lower edge of the partition plate to a predetermined position, and further downward from the upper edge of the second partition plate formed corresponding to the lower notches of the first partition plates. In the partition made of corrugated paperboard, in which a plate surface between the upper edge of each first partition plate and the upper end of the lower cut is inserted into a pair of upper cuts extending to a predetermined position toward the front, the bottom plate is And the upper surfaces of the bottom plates through a first fold line extending along the center between the first partition plates. The second partition plate is foldable in a direction in which one side surface of the second partition plate is overlapped via a second fold line extending along the center of both upper cuts. The upper notches of the second partition plate are formed in a shape that bends or curves toward one side symmetrically about the second fold line and is inserted into each upper notch. Each of the first partition plates is curved along each of the upper cuts and elastically press-fits the upper cuts.

本発明の仕切体は、一対の第１仕切板と底板とが一体に連設されているので、両第１仕切板の間隔が底板によって維持され、第１仕切板と第２仕切板とが直交する仕切り状態を確実に維持することができる。 In the partition body of the present invention, since the pair of first partition plates and the bottom plate are integrally connected, the distance between the first partition plates is maintained by the bottom plate, and the first partition plate and the second partition plate are An orthogonal partition state can be reliably maintained.

仕切り状態の第２仕切板は、底板に形成された底部切込みを介して底板を下方から貫通して、両第１仕切板の下切込みに挿着されているので、組立状態で箱内に収納したとき、振動や衝撃によって第２仕切板のみが上方に抜け出すことがなく、第１仕切板及び第２仕切板の高さ寸法を小として仕切体の材料を削減することが可能となる。また、第２仕切板を把持して上方に持ち上げても、両第１仕切板から第２仕切板のみが上方に抜け出すことがなく、組立状態で箱内に収納する際に取り扱いが容易である。更に、第２仕切板の両上切込みは、屈曲又は湾曲する形状であるので、各上切込みに挿着された各第１仕切板は各上切込みに沿って湾曲して弾発的に該上切込みに圧接係合し、例えば、第１仕切板を把持して上方に持ち上げた場合でも、両第１仕切板からの第２仕切板の抜落ちを防止することができる。 The second partition plate in the partition state penetrates the bottom plate from below through the bottom notch formed in the bottom plate and is inserted into the lower notches of both first partition plates, so that it is stored in the box in the assembled state. In this case, only the second partition plate does not slip upward due to vibration or impact, and the height of the first partition plate and the second partition plate can be reduced to reduce the partition material. Further, even if the second partition plate is gripped and lifted upward, only the second partition plate does not come out upward from both first partition plates, and handling is easy when stored in a box in an assembled state. . Further, since both the upper notches of the second partition plate are bent or curved, each of the first partition plates inserted into each upper notch is curved along each upper notch and is elastically moved upward. For example, even when the first partition plate is gripped and lifted upward by pressure-engaging with the notch, the second partition plate can be prevented from falling off from both first partition plates.

本発明の仕切体を折り畳むときには、前記第１折畳線に沿って底板をその中央から内側面同士が重合する方向に折り曲げる。同時に、前記第２折畳線に沿って第２仕切板をその中央から左右側が重合する方向に半分に折り曲げる。このように、前記底板と前記第２仕切板とを夫々半分に折り曲げるだけで、半分に折り曲げられた第２仕切板が両第１仕切板間に折り込まれて重合し、極めて容易に偏平に折り畳むことができる。 When the partition of the present invention is folded, the bottom plate is folded along the first fold line in the direction in which the inner surfaces overlap from the center. At the same time, the second partition plate is folded in half along the second fold line in the direction in which the left and right sides overlap from the center. In this way, by simply folding the bottom plate and the second partition plate in half, the second partition plate folded in half is folded and overlapped between the first partition plates, and it is very easily folded flat. be able to.

また、折り畳んだ状態から、底板と第２仕切板とを夫々扁平に広げるだけで、第１仕切板と第２仕切板とが直交する仕切り状態を容易に形成することができる。このとき、第２仕切板の両上切込みが屈曲又は湾曲しており、第２仕切板を扁平に広げるときに、上切込みに挿着された第１仕切板が弾発的に湾曲するので、扁平となった第２仕切板の第２折畳線の両側から面方向に第１仕切板の付勢力が付与されるので、第２仕切板の折癖が解消されて第２仕切板の扁平状態が維持される。しかも、第１仕切板の弾発的な湾曲により底板に対してその両側から第１仕切板の付勢力が付与されるので、底板に張りが生じて、底板の折癖が解消される。これによって、折り畳んだ状態から仕切り状態とされた仕切体は、折り畳んだときに生じた折癖が解消されて、仕切り状態を確実に維持することができる。 Further, from the folded state, the partition state in which the first partition plate and the second partition plate are orthogonal to each other can be easily formed only by flattening the bottom plate and the second partition plate. At this time, both upper cuts of the second partition plate are bent or curved, and when the second partition plate is flattened, the first partition plate inserted into the upper cut is elastically curved, Since the biasing force of the first partition plate is applied in the surface direction from both sides of the second folding line of the flat second partition plate, the folding of the second partition plate is eliminated and the flatness of the second partition plate is eliminated. State is maintained. Moreover, since the urging force of the first partition plate is applied to the bottom plate from both sides due to the elastic bending of the first partition plate, the bottom plate is stretched and the bottom plate is not broken. Thereby, the folding body which was made into the partition state from the folded state can eliminate the crease produced when folded, and can maintain the partition state reliably.

なお、上切込みの形状において屈曲する方向又は湾曲する方向は第２仕切板の外側（側縁に向かう方向）でも内側（第２折畳線に向かう方向）でもよい。そして、両上切込みは互いに第２折畳線を軸とする左右対称に設けられているので、例えば、一方の上切込みが外側に屈曲又は湾曲しているときには、他方の上切込みも反対側の外側に屈曲又は湾曲し、両第１仕切板の弾発的な湾曲から得られる底板及び第２仕切板への付勢力を均等に発生させることができる。 In the shape of the upper cut, the direction of bending or the direction of bending may be the outside (direction toward the side edge) or the inside (direction toward the second fold line) of the second partition plate. Since both the upper cuts are provided symmetrically with respect to the second fold line as an axis, for example, when one upper cut is bent or curved outward, the other upper cut is also on the opposite side. Bending or curving outwards, the urging force to the bottom plate and the second partition plate obtained from the elastic curvature of both first partition plates can be generated evenly.

また、本発明において、前記第１仕切板は、材料となる段ボール板紙のフルート部が高さ方向に沿った縦向きとなるよう起立され、前記第２仕切板は、材料となる段ボール板紙のフルート部が横向きとなるように両第１仕切板に組みつけられ、前記第２折畳線は、一方側のライナー部及びフルート部に切れ目を形成することにより他方側のライナー部をヒンジとして折り曲げ自在とされていることが好ましい。 Further, in the present invention, the first partition plate is erected so that the flute portion of the corrugated cardboard serving as the material is oriented vertically along the height direction, and the second partition plate is the flute of the corrugated cardboard serving as the material. The second fold line is foldable with the other liner part as a hinge by forming a cut in the one liner part and the flute part. It is preferable that

一般に段ボール板紙は、フルート部の向きに沿って折れ目が生じやすく、比較的小さな力で折れ曲がりが生じる。しかし、フルート部の向きに直交する方向に対しては比較的折れ曲がり難く、弾発的に撓ませることが容易となる。そこで、本発明においては、前記第１仕切板をフルート部が縦向きとなるよう起立さているので、第１仕切板を第２仕切板の上切込みに係合させたとき、第１仕切板にフルート部に沿った折れ曲がりが生じることなく確実に弾発的な撓みを得ることができる。 In general, corrugated paperboard tends to bend along the direction of the flute, and bends with a relatively small force. However, it is relatively difficult to bend in the direction orthogonal to the direction of the flute portion, and it is easy to bend flexibly. Therefore, in the present invention, since the first partition plate is erected so that the flute portion is vertically oriented, when the first partition plate is engaged with the upper notch of the second partition plate, the first partition plate Elastic bending can be obtained reliably without bending along the flute portion.

また、段ボール板紙は、フルート部の向きに沿った方向に対する強度が高い。そこで、本発明においては、前記第２仕切板を、フルート部が横向きとなるように両第１仕切板に組みつけることで、第２仕切板の上切込みがフルート部の向きに直交して延び、これによって、上切込みにおける第１仕切板への圧接状態を確実にえることができる。 Corrugated paperboard has high strength in the direction along the direction of the flute. Therefore, in the present invention, the second partition plate is assembled to both first partition plates so that the flute portions are sideways, so that the upper notch of the second partition plate extends perpendicular to the direction of the flute portions. As a result, it is possible to reliably obtain the pressure contact state with the first partition plate in the upper cut.

そして更に、前記第２仕切板においては、一方側のライナー部及びフルート部に切れ目を形成することにより他方側のライナー部をヒンジとして折り曲げ自在とする第２折畳線を設けたので、第２仕切板が扁平状態で第１仕切板に直交するとき、第２折畳線の切れ目によるフルート部の切断端縁同士が比較的平坦に当接し、第１仕切板からの付勢力を受けたときに安定して確実に第２仕切板の扁平状態を維持することができる。これにより、折り畳んだ状態から、第２仕切板とを夫々扁平に広げて仕切り状態を形成したときに、第２仕切板の折癖を一層確実に解消することができ、仕切り状態を確実に維持することができる。 In the second partition plate, the second fold line is provided so that the second liner part can be bent as a hinge by forming a cut in the liner part and the flute part on one side. When the partition plate is flat and orthogonal to the first partition plate, the cut edges of the flute portion due to the break of the second fold line abut against each other relatively flatly and receive a biasing force from the first partition plate The flat state of the second partition plate can be maintained stably and reliably. As a result, when the partition state is formed by flattening the second partition plate from the folded state, the folding of the second partition plate can be more reliably eliminated, and the partition state is reliably maintained. can do.

本実施形態の仕切体１は、図示しない包装用箱体に収容して瓶等の被包装物の収納スペースを各瓶毎に区画するものである。図１及び図２に示すように、仕切体１は、矩形状の底板２と、該底板２の両側縁に起立する一対の第１仕切板３，４とを備えている。両第１仕切板３，４には、両第１仕切板３，４に直交して３枚の第２仕切板５，６，７が所定間隔を存して組み付けられている。 The partition 1 according to the present embodiment is housed in a packaging box (not shown), and divides a storage space for an object to be packaged such as a bottle for each bottle. As shown in FIGS. 1 and 2, the partition 1 includes a rectangular bottom plate 2 and a pair of first partition plates 3 and 4 that stand on both side edges of the bottom plate 2. Three first partition plates 5, 6, 7 are assembled to the first partition plates 3, 4 at a predetermined interval so as to be orthogonal to the first partition plates 3, 4.

図３に展開して示すように、底板２と一対の第１仕切板３，４とは、段ボール板紙を打ち抜いて形成され、両第１仕切板３，４は、その夫々が底板２の両側縁に折目線８，９を介して一体に連設されている。底板２には、両第１仕切板３，４の下縁に平行な第１折畳線１０が中央に延設されている。第１折畳線１０は、底板２をその中央から半分に折り曲げ自在とするものである。底板２には、第２仕切板５，６，７に対応して貫通自在の底部切込み１１が形成されている。両第１仕切板３，４には、その下縁から上方に向かって所定の位置まで延びる下切込み１２，１３が各底部切込み１１の両端に連続して形成されている。なお、底板２と一対の第１仕切板３，４とは、段ボール板紙のライナー部Ｌの一部を破断して示すように、フルート部Ｆが第１仕切板３，４の高さ方向に沿って縦方向となるように形成されている。 As shown in FIG. 3, the bottom plate 2 and the pair of first partition plates 3, 4 are formed by punching corrugated cardboard, and each of the first partition plates 3, 4 is on both sides of the bottom plate 2. It is continuously connected to the edge via the crease lines 8 and 9. A first fold line 10 parallel to the lower edges of the first partition plates 3 and 4 is extended to the center of the bottom plate 2. The first fold line 10 allows the bottom plate 2 to be bent in half from its center. The bottom plate 2 is formed with a bottom notch 11 that can penetrate through the second partition plates 5, 6, and 7. Both first partition plates 3, 4 are formed with lower notches 12, 13 extending continuously from the lower edge to a predetermined position at both ends of each bottom notch 11. The bottom plate 2 and the pair of first partition plates 3 and 4 are such that the flute portion F extends in the height direction of the first partition plates 3 and 4 as shown by breaking a part of the liner portion L of the corrugated paperboard. It is formed so that it may become a vertical direction along.

図３に示すように、３枚の第２仕切板５，６，７は、共に同一形状に形成されており、その上縁から下方に延びる一対の上切込み１４，１５が形成されている。各上切込み１４，１５は、各下切込み１２，１３に対応して噛み合う位置に設けられている。また、各第２仕切板５，６，７の両第１仕切板３，４間の中央に対応する位置には、上縁から下縁に至る第２折畳線１６が形成されている。第２折畳線１６は、各第２仕切板５，６，７をその中央から半分に折り曲げ自在とする。更に、各第２仕切板５，６，７に設けられている上切込み１４，１５は、各第２仕切板５，６，７の側縁に向かって僅かに屈曲している。このとき、一対の上切込み１４，１５同士は、第２折畳線１６を介して左右対称に設けられている。 As shown in FIG. 3, the three second partition plates 5, 6, 7 are both formed in the same shape, and a pair of upper cuts 14, 15 extending downward from the upper edge thereof are formed. The upper cuts 14 and 15 are provided at positions that mesh with the lower cuts 12 and 13. A second fold line 16 extending from the upper edge to the lower edge is formed at a position corresponding to the center between the first partition plates 3, 4 of the second partition plates 5, 6, 7. The second fold line 16 allows each of the second partition plates 5, 6, and 7 to be bent in half from the center. Furthermore, the upper notches 14 and 15 provided in the second partition plates 5, 6 and 7 are slightly bent toward the side edges of the second partition plates 5, 6 and 7. At this time, the pair of upper cuts 14 and 15 are provided symmetrically via the second folding line 16.

なお、各第２仕切板５，６，７は、段ボール板紙のライナー部Ｌの一部を破断して示すように、フルート部Ｆが横方向となるように形成されている。また、第２折畳線１６は、図４に一部を示すように、一方側のライナー部Ｌ１からフルート部Ｆに切れ目を形成することにより他方側のライナー部Ｌ２をヒンジとして折り曲げ自在とされている。 Each of the second partition plates 5, 6, and 7 is formed such that the flute portion F is in the lateral direction as shown by breaking a part of the liner portion L of the corrugated paperboard. Further, as shown in part in FIG. 4, the second folding line 16 can be bent with the liner portion L2 on the other side as a hinge by forming a cut from the liner portion L1 on one side to the flute portion F. ing.

そして該仕切体１は、図２に示すように、各第２仕切板５，６，７を底板２の下方から底板２の各底部切込み１１を貫通させ、各第１仕切板３，４の下切込み１２，１３に各第２仕切板５，６，７の上切込み１４，１５を噛み合わせるように組み付ける。こうすることで、図１に示すように、各仕切板３，４，５，６，７が互いに直交する格子状に組み付けられ、箱体の内部を１２等分のスペースに区画する仕切り状態となる。 As shown in FIG. 2, the partition 1 passes through the second partition plates 5, 6, and 7 from the bottom of the bottom plate 2 through the bottom cuts 11 of the bottom plate 2. The lower notches 12 and 13 are assembled so that the upper notches 14 and 15 of the second partition plates 5, 6 and 7 are engaged with each other. By doing so, as shown in FIG. 1, the partition plates 3, 4, 5, 6, and 7 are assembled in a lattice shape orthogonal to each other, and the partition state that partitions the interior of the box into 12 equal spaces Become.

本実施形態の仕切体１を折り畳む時には、図１を参照して、底板２を第１折畳線１０を介して下方に突出するように半分に折り曲げ、同時に、第２仕切板５，６，７を第２折畳線１６を介して横方向に半分に折り曲げる。こうすることによって、底板２の第１折畳線１０及び第２仕切板５，６，７の第２折畳線１６の曲げ角度が鋭角に折れ曲がり、第１仕切板３，４及び第２仕切板５，６，７が互いに重合し、図５に示すように、偏平に折り畳まれる。そして、図５に示す折畳状態にある仕切体１から図１に示す仕切り状態を形成する場合には、両第１仕切板３，４同士を互いに離反させる。これにより、底板２の第１折畳線１０及び第２仕切板５，６，７の第２折畳線１６の折り曲げが解除され、第１仕切板３，４に対して第２仕切板５，６，７が直交して容易に仕切り状態を形成することができる。 When folding the partition 1 of the present embodiment, referring to FIG. 1, the bottom plate 2 is folded in half so as to protrude downward via the first fold line 10, and at the same time, the second partition plates 5, 6, 7 is folded in half in the lateral direction via the second fold line 16. By doing so, the bending angle of the first fold line 10 of the bottom plate 2 and the second fold line 16 of the second partition plates 5, 6, 7 is bent at an acute angle, and the first partition plates 3, 4 and the second partition plate are bent. The plates 5, 6 and 7 are superposed on each other and are folded flat as shown in FIG. And when forming the partition state shown in FIG. 1 from the partition body 1 in the folded state shown in FIG. 5, the first partition plates 3 and 4 are separated from each other. Thereby, the bending of the first fold line 10 of the bottom plate 2 and the second fold line 16 of the second partition plates 5, 6, 7 is released, and the second partition plate 5 with respect to the first partition plates 3, 4 is released. , 6 and 7 are perpendicular to each other and a partitioning state can be easily formed.

そして、本実施形態の仕切体１によれば、図６に側面視するように、第２仕切板５に設けられている上切込み１４，１５が屈曲していることにより、上切込み１４，１５に挿着された第１仕切板３，４が弾発的に僅かに湾曲する。これによって、第１仕切板３，４が第２仕切板５を押さえ込むように付勢するので、第２折畳線１６による不用意な第２仕切板５の折れ曲がりが確実に防止され、底板２にも張りが発生し、仕切り状態が確実に維持される。図６においては、第２仕切板５のみが図示されているが、第２仕切板６及び７においても同様である。 And according to the partition 1 of this embodiment, the upper notches 14 and 15 are obtained by bending the upper notches 14 and 15 provided in the second partition plate 5 as viewed from the side in FIG. The first partition plates 3 and 4 that are inserted in are bent slightly elastically. As a result, the first partition plates 3 and 4 are urged to press the second partition plate 5, so that inadvertent bending of the second partition plate 5 by the second fold line 16 is surely prevented, and the bottom plate 2. Also, tension is generated and the partition state is reliably maintained. In FIG. 6, only the second partition plate 5 is shown, but the same applies to the second partition plates 6 and 7.
