Description

本発明は、素板ガラス、液晶表示用やプラズマ表示用のガラス基板、タッチセンサー、タッチパネル等の各種のガラス基板やパネルその他の板状体を搬送、保管するのに使用する板状体の搬送用容器に関するものである。   The present invention is for transporting plate-like bodies used for transporting and storing various glass substrates such as glass plates, liquid crystal display and plasma display glass substrates, touch sensors, touch panels, and other plate-like bodies. It relates to the container.

従来より、素板ガラス、液晶表示用のガラス基板等の比較的大型のガラス基板、あるいは太陽電池パネル等のパネルその他の衝撃に弱い板状体を収納して搬送するための搬送用容器として、緩衝性を有する合成樹脂発泡体製の容器本体と蓋体とよりなり、容器本体の一方の相対向する側壁内面に等間隔に並設された縦溝に、前記の板状体を１枚ずつ挿入して相互に接触させないように直立状態に支持して収納するようにしたものが一般に使用されていた。   Conventionally, as a transport container for storing and transporting a plate-like glass, a relatively large glass substrate such as a glass substrate for liquid crystal display, or a panel such as a solar battery panel or other impact-sensitive plate-like body, it is buffered. Each of the plate-like bodies is inserted into vertical grooves formed at equal intervals on the inner surface of one opposite side wall of the container body. In order to prevent them from coming into contact with each other, the ones that are supported and stored in an upright state are generally used.

近年、液晶テレビやプラズマテレビの大型化の需要の増大から、テレビ用のガラス基板としても、縦横の一方もしくは両方が１００ｃｍを超える大型のガラス基板も採用されており、このため、かかるガラス基板を搬送するための運搬用容器も大型化している。   In recent years, due to an increase in demand for large-sized liquid crystal televisions and plasma televisions, large-sized glass substrates in which one or both of the vertical and horizontal directions exceed 100 cm have been adopted as glass substrates for televisions. Transport containers for transport are also becoming larger.

しかし、従来の側壁内面の縦溝によりガラス基板を直立状態にして収容する方式では、大型で重くなったガラス基板のために、ガラス基板自体が自重によって曲げ変形したり、ガラス基板の重量が容器本体の底部に集中して負荷されることで、容器底部が圧縮変形し、クッション機能や衝撃緩和機能が損なわれる虞があった。   However, in the conventional method of accommodating the glass substrate in an upright state by the vertical groove on the inner surface of the side wall, the glass substrate itself is bent and deformed by its own weight because of the large and heavy glass substrate, or the weight of the glass substrate is a container. When the load is concentrated on the bottom of the main body, the bottom of the container is compressed and deformed, and the cushion function and the impact relaxation function may be impaired.

かかる問題を生じさせないために、特許文献１及び２に例示するように、容器本体内に、ガラス基板とスペーサとして防護用シートとを交互に重ねて平置き状態で収納し、各ガラス基板を防護用シートを介して面で受けるようにした搬送用容器も出現している。特に、高価なパネル等の板状体の場合は、１枚ずつの板状体を収納した容器を積み重ねして、バンド掛けして梱包することも行われている。これらの搬送用容器は、ガラス基板の撓み変形に起因する破損や割れの虞がなく、パネル等の板状体の保護を良好になすものである。   In order not to cause such a problem, as exemplified in Patent Documents 1 and 2, glass substrates and protective sheets as spacers are alternately stacked and stored in a flat state in the container body to protect each glass substrate. There are also containers for transportation that are received on the surface via a sheet for use. In particular, in the case of a plate-like body such as an expensive panel, containers each containing a plate-like body are stacked and banded and packed. These containers for transportation do not have the risk of breakage or cracking due to the bending deformation of the glass substrate, and can favorably protect plate-like bodies such as panels.

ところで、この種のパネルやガラス基板等の板状体の種類によっては、収納される板状体の面直角方向の支持荷重、特には段積み時の積み重ね荷重を、周縁部の若干幅（１０ｍｍ以下）でしか受けることができない場合があり、また場合によっては、面直角方向の荷重を全く受けることができない場合がある。   By the way, depending on the type of the plate-like body such as this type of panel or glass substrate, the support load in the direction perpendicular to the surface of the plate-like body to be stored, particularly the stacking load at the time of stacking, In some cases, and in some cases, a load in a direction perpendicular to the plane may not be received at all.

しかしながら、前記特許文献１及び２のいずれも、容器内に１枚の板状体を収納して段積みした場合に、面直角方向の段積み荷重を受けないようになっているが、これらいずれの場合も単一の容器として形成されており、該容器内の凹部に嵌め込み収納する必要があり、収納作業や取り出し作業が面倒なものである。しかも容器同士が相互に嵌合する構造にしておかなければならず、コスト高なものになる。   However, both Patent Documents 1 and 2 do not receive a stacking load in a direction perpendicular to the plane when a single plate-like body is stored and stacked in a container. In this case, the container is formed as a single container, and needs to be fitted and stored in a recess in the container, which makes the storing operation and taking-out operation troublesome. In addition, the container must be structured to be fitted to each other, which increases the cost.

本発明は、上記に鑑みて、若干幅の周縁部以外に全く面直角方向の荷重を受けることができないか、もしくは全く面直角方向の荷重を受けることができない板状体を、板状スペーサを介在させて、積み重ね荷重を殆どあるいは全く負荷させずに収納して保持でき、その保護を良好になすことができる板状体の搬送用容器を提供するものである。   In view of the above, the present invention provides a plate-like body that cannot receive a load in a direction perpendicular to the plane at all other than a peripheral portion of a slight width or a plate-like spacer that cannot receive a load in a direction perpendicular to the plane at all. It is an object of the present invention to provide a container for transporting a plate-like body that can be stored and held with little or no stacking load interposed therebetween, and can be well protected.

上記の課題を解決する本発明は、平面矩形の板状体を、板状スペーサを介在させて複数枚を重ねて平置き状態で容器本体内に収納し搬送するための搬送用容器であって、前記板状スペーサは、容器本体の収納部に対応した平面矩形の板状をなし、少なくとも一方の相対向辺部に突出縁部が形成され、該突出縁部の厚みがその内方のスペーサ本体部の厚みより大きく、積み重ね荷重を前記突出縁部で受支するようにしたことを特徴とする。   The present invention that solves the above problems is a transport container for storing and transporting a planar rectangular plate-like body in a container body in a flat state by stacking a plurality of pieces with a plate-like spacer interposed therebetween. The plate-like spacer has a flat rectangular plate shape corresponding to the storage portion of the container body, and a protruding edge is formed on at least one opposite side portion, and the thickness of the protruding edge is the inner spacer. It is larger than the thickness of the main body, and the stacked load is supported by the protruding edge.

この搬送用容器は、素板ガラス、液晶表示用のガラス基板等の板状体を板状スペーサを介在させて容器本体内に重ねて収納するが、この際、板状スペーサの相対向辺部に設けた突出縁部で積み重ね荷重を受支することで、各板状スペーサ間に保持した板状体に積み重ね荷重を負荷させることがない。   In this transport container, a plate-like body such as a plate glass or a glass substrate for liquid crystal display is stored in a container body with a plate-like spacer interposed therebetween. By receiving the stacking load at the provided protruding edge portion, the stacking load is not applied to the plate-like body held between the plate-like spacers.

前記の板状体の搬送用容器において、前記突出縁部が容器本体の相対向側壁の内面に形成された嵌合凹部に上方より嵌合できるように形成されており、前記突出縁部を嵌合凹部に嵌合して複数枚の各板状スペーサを、各スペーサ間に板状体を挟んで段積みした状態において、積み重ね荷重を該突出縁部で受支するようにしたものとする。これにより、前記板状スペーサは、前記突出縁部を容器本体の相対向する側壁に有する嵌合凹部に嵌合することで、位置ずれなく積み重ねることができ、しかも、積み重ね荷重を該突出縁部で受支できる。   In the transport container for the plate-like body, the protruding edge is formed so as to be fitted from above into a fitting recess formed on the inner surface of the opposite side wall of the container body, and the protruding edge is fitted. It is assumed that the stacking load is received and supported by the projecting edge portion in a state where the plurality of plate-like spacers are fitted in the mating recesses and stacked with the plate-like bodies sandwiched between the spacers. As a result, the plate-like spacer can be stacked without misalignment by fitting into the fitting recesses having the protruding edges on opposite side walls of the container body, and the stacking load can be applied to the protruding edges. It can be received and received.

前記の板状体の搬送用容器において、前記板状スペーサの板状体が収納される面の周縁部には、収納される板状体の接触支持可能な周縁部との対応位置に保持用の凸部が設けられており、各スペーサ間に板状体を挟んで複数枚の前記板状スペーサを前記突出縁部で積み重ねた状態において、前記凸部より内方部において収納される板状体と板状体が収納される面との間に間隔を保有するように設けられてなるものとすることができる。この場合、前記保持用の凸部が板状体の支持可能な周縁部で浮き上がり等の動きを規制でき、しかも、凸部より内方部において、板状体と板状体が収納される面との間に間隔を保有するため、荷重が負荷されることがない。   In the transport container for the plate-like body, the peripheral edge of the surface of the plate-like spacer in which the plate-like body is accommodated is held at a position corresponding to the peripheral edge where the plate-like body to be accommodated can be supported. In the state where a plurality of the plate-like spacers are stacked on the protruding edge portion with a plate-like body sandwiched between the spacers, the plate-like shape is housed in the inner portion from the convex portion. It can be provided so as to have a gap between the body and the surface on which the plate-like body is stored. In this case, the holding convex portion can regulate the movement such as lifting at the supportable peripheral portion of the plate-like body, and the surface on which the plate-like body and the plate-like body are stored is located inward from the convex portion. Since there is an interval between the load, no load is applied.

前記の板状体の搬送用容器において、前記突出縁部の厚みが、前記板状スペーサの前記保持用の凸部を含むスペーサ本体部の厚みと同じか、または該凸部を含むスペーサ本体部の厚みより大きく形成されており、複数の板状スペーサを各スペーサ間に板状体を挟んで前記突出縁部で積み重ねた状態において、板状スペーサの前記保持用の凸部が、板状体の周縁部と接するか、もしくはクリアランスを存して対向するように設けられてなるものとすることができる。これにより、板状体の浮き上がり等の動きを前記凸部により規制することができ、しかも凸部の部分においても板状体に対し過度の荷重を負荷させることがない。   In the container for transporting the plate-like body, the thickness of the protruding edge portion is the same as the thickness of the spacer main body portion including the holding convex portion of the plate spacer, or the spacer main body portion including the convex portion. In the state in which a plurality of plate-like spacers are stacked at the protruding edge portions with the plate-like bodies sandwiched between the spacers, the holding convex portions of the plate-like spacers are formed into plate-like bodies. It may be provided so as to be in contact with the peripheral edge portion of the surface or to be opposed to each other with a clearance. Thereby, the movement of the plate-like body, such as lifting, can be restricted by the convex portion, and an excessive load is not applied to the plate-like body even at the portion of the convex portion.

前記の板状体の搬送用容器において、前記保持用の凸部が、外端部を頂部として内方に向かって傾斜面をなしているものとすることができる。これにより、前記凸部は、板状体に対し面直角方向の荷重を受けても差し支えのない周縁部の外端部分でのみ当接することになる。   In the plate-like transport container, the holding convex portion may have an inclined surface inward with the outer end as a top. Thereby, the said convex part contact | abuts only in the outer end part of the peripheral part which does not interfere even if it receives the load of a surface orthogonal direction with respect to a plate-shaped object.

前記の板状体の搬送用容器において、容器本体の少なくとも一方の相対向する両側壁の内面と、これに対応する前記板状スペーサの相対向辺との間に、板状体取り出し用の凹部が設けられてなるものとすることができる。   In the plate-like container for transporting the plate-like body, a recess for taking out the plate-like body is provided between the inner surfaces of at least one opposite side walls of the container body and the opposite sides of the plate-like spacer corresponding thereto. Can be provided.

上記したように、本発明の板状体の搬送用容器によれば、ガラス基板等の板状体、特には面直角方向に周縁部の若干幅しか受けることができないか、又は殆ど全く面直角方向の荷重を受けることができない板状体を、板状スペーサーを介して安定性よく収納して保持でき、特に板状スペーサ同士が位置ずれする虞がないため、各板状スペーサ間に収納された板状体を安定性よく保持でき、その保護を良好になし得る。   As described above, according to the container for transporting a plate-like body of the present invention, a plate-like body such as a glass substrate, in particular, can receive only a slight width of the peripheral edge in the direction perpendicular to the plane, or is almost completely perpendicular to the plane. The plate-like body that cannot receive the load in the direction can be stably stored and held via the plate-like spacer, and the plate-like spacers are not housed between the plate-like spacers. The plate-like body can be held with good stability and can be well protected.

特に、板状スペーサは、スペーサ本体部より外方に突出した突出縁部で容器本体の側壁内面の凹部に嵌合することで位置決めして位置ずれを生じさせることなく積み重ねることができ、しかもその積み重ね荷重を該突出縁部で受支するようにしたので、板状体自体に積み重ね荷重を負荷させることがない上、板状体を保持するスペーサ本体部の精度を過度に高くする必要がなく、容器本体と同素材の合成樹脂発泡体等による成形により容易に製作できることになり、コスト安価に提供できる。   In particular, the plate-like spacers can be stacked without being displaced by being positioned by fitting into the recesses on the inner surface of the side wall of the container main body at the protruding edge protruding outward from the spacer main body. Since the stacking load is received and supported by the protruding edge, it is not necessary to apply the stacking load to the plate-like body itself, and it is not necessary to excessively increase the accuracy of the spacer main body holding the plate-like body. It can be easily manufactured by molding with a synthetic resin foam of the same material as the container body, and can be provided at a low cost.

次に本発明の実施の形態を図面に示す実施例に基づいて説明する。   Next, embodiments of the present invention will be described based on examples shown in the drawings.

この実施例の搬送用容器Ａは、収納対象のガラス基板等の板状体Ｂを、表裏面に樹脂フイルムや紙等の保護シートＣを重ねて保護した状態で、後述する板状スペーサ１０を介在させて複数枚を重ねて平置き状態にして平面長方形や正方形の平面矩形の容器本体１に収納し保持して搬送する容器であり、次のような構成よりなる。   In this embodiment, the container A for transporting a plate-like body B such as a glass substrate to be stored is protected by overlapping a protective sheet C such as a resin film or paper on the front and back surfaces. A container which is placed in a flat state by interposing a plurality of sheets in a flat rectangular or square flat rectangular container body 1 and is held and transported and has the following configuration.

容器本体１は、主として緩衝性のある合成樹脂発泡体により成形されてなり、底部２より立ち上がった四周の各側壁３，３，４，４により収納部５が形成されている。この容器本体１には、少なくとも一方の相対向する側壁、例えば長辺側の側壁３，３の内側面に、後述する板状スペーサ１０の突出縁部が嵌合する上下方向の嵌合凹部６，６が形成されている。この容器本体１の収納部５は、所要数枚の板状体Ｂと板状スペーサ１０を交互に重ねて収納できる深さに形成されている。板状スペーサ１０の厚みによっても異なるが、例えば１０枚の板状体Ｂと板状スペーサ１０を交互に重ねて収納できるように形成される。   The container main body 1 is mainly formed of a synthetic resin foam having a buffering property, and a storage portion 5 is formed by the four side walls 3, 3, 4 and 4 rising from the bottom portion 2. The container body 1 includes a fitting recess 6 in the vertical direction in which a protruding edge of a plate-like spacer 10 described later is fitted to at least one opposite side wall, for example, the inner side surface of the long side walls 3 and 3. , 6 are formed. The storage portion 5 of the container body 1 is formed to a depth that allows the required number of plate-like bodies B and plate-like spacers 10 to be alternately stacked. For example, 10 plate-like bodies B and plate-like spacers 10 are formed so that they can be alternately stacked and stored, although it depends on the thickness of the plate-like spacer 10.

図の場合、前記容器本体１の四周の側壁３，３，４，４による隅角部の内側には、底部２の隅角部の凹部から連続する上下方向の切欠３ａが形成されており、収納される板状体Ｂのコーナー部を側壁３，３，４，４に接触させずに保持でき、容器の角落下時の衝撃緩和できるように設けられている。   In the case of the figure, a vertical notch 3a continuous from the concave portion of the corner portion of the bottom portion 2 is formed inside the corner portion by the four side walls 3, 3, 4 and 4 of the container body 1, The corners of the plate-like body B to be stored can be held without being in contact with the side walls 3, 3, 4 and 4, and are provided so as to reduce the impact when the container is dropped.

板状スペーサ１０は、主として前記容器本体１と同様の合成樹脂発泡体により成形されており、容器本体１の収納部空間に対応した平面矩形のスペーサ本体部１１を有し、該スペーサ本体部１１の少なくとも一方の相対向辺部、例えば長辺側の両辺部に、前記容器本体１の長辺側の側壁３，３の内面に形成された嵌合凹部６，６に上方より嵌合できる突出縁部１２，１２が形成されている。この突出縁部１２，１２は、その厚みＴがスペーサ本体部１１の厚みより大きく、複数枚の各板状スペーサ１０を前記突出縁部１２，１２を嵌合凹部６，６に嵌合して板状体Ｂを保持して重ねた状態において、積み重ね荷重を前記突出縁部１２，１２で受支するようになっている。すなわち、容器本体１の底部２上及び板状スペーサ１０上に載置されて収納される板状体Ｂと、その上の板状スペーサ１０との間に接触を回避するための数ｍｍの間隙Ｓを保有することで、板状体１０の接触支持可能な周縁部、特には面直角方向の荷重を受けて支持できる若干幅の周縁部よりも内方部には積み重ね荷重が負荷されないようになっている。   The plate-like spacer 10 is mainly formed of the same synthetic resin foam as that of the container main body 1, and has a planar rectangular spacer main body 11 corresponding to the storage space of the container main body 1. A protrusion that can be fitted from above into fitting recesses 6 and 6 formed on the inner surfaces of the side walls 3 and 3 on the long side of the container body 1 on at least one opposite side of the container, for example, both sides on the long side Edges 12, 12 are formed. The protruding edges 12 and 12 have a thickness T larger than the thickness of the spacer body 11, and a plurality of plate-like spacers 10 are fitted to the protruding edges 12 and 12 into the fitting recesses 6 and 6. In the state where the plate-like body B is held and stacked, the stacked load is received and supported by the protruding edge portions 12 and 12. That is, a gap of several mm for avoiding contact between the plate-like body B placed and stored on the bottom 2 of the container body 1 and on the plate-like spacer 10 and the plate-like spacer 10 thereon. By holding S, the stacking load is not applied to the inner peripheral portion of the peripheral portion of the plate-like body 10 that can be supported by contact, particularly the peripheral portion of a slight width that can be supported by receiving a load in the direction perpendicular to the plane. It has become.

図示する実施例の場合、前記板状スペーサ１０の板状体Ｂが収納される面となる下面、特に前記スペーサ本体部１１の下面１１ａの周縁部には、収納される板状体Ｂの周縁部、好ましくは接触可能な周縁部との対応位置に保持用の凸部１３が設けられており、各スペーサ間に板状体Ｂを挟んで複数枚の前記板状スペーサ１０を前記突出縁部１２，１２で積み重ねた状態において、底部２上及び板状スペーサ１０上に載置された板状体Ｂの周縁部とごく僅かなクリアランス（例えば０．２〜１．０ｍｍ程度）を存して対向するか、もしくは軽く接触して支持するように対向し、該板状体Ｂの浮き上がり等の動きを規制する役目を果たすように設けられている。そのため、前記突出縁部１２，１２は、前記凸部１３と同じ下面側に増肉されることにより、その厚みＴが板状スペーサ１０の前記凸部１３を含むスペーサ本体部１１の厚みと同じか、もしくは該スペーサ本体部１１の厚みより僅かに大きく形成されている。   In the case of the illustrated embodiment, the lower surface of the plate-like spacer 10 on which the plate-like body B is accommodated, particularly the peripheral edge of the lower surface 11a of the spacer main body 11, the periphery of the plate-like body B to be accommodated. , Preferably a protrusion 13 for holding is provided at a position corresponding to the peripheral edge that can be contacted, and a plurality of the plate spacers 10 are inserted into the protruding edge portion with a plate-like body B interposed between the spacers. 12 and 12, there is a slight clearance (for example, about 0.2 to 1.0 mm) from the peripheral portion of the plate-like body B placed on the bottom portion 2 and the plate-like spacer 10. They are opposed to each other, or are opposed so as to be supported lightly, and are provided so as to play a role of regulating the movement of the plate-like body B such as lifting. Therefore, the protruding edge portions 12 and 12 are increased in thickness on the same lower surface side as the convex portion 13 so that the thickness T is the same as the thickness of the spacer main body portion 11 including the convex portion 13 of the plate-like spacer 10. Alternatively, it is formed slightly larger than the thickness of the spacer body 11.

前記保持用の凸部１３，１３は、外端部を頂部１３ａとして内方に向かって傾斜面をなしており、下段の板状スペーサ１０上あるいは底部２上の板状体Ｂに対し、面直角方向の荷重を受けても差し支えのない若干幅の周縁部の外端部分で当接するようになっている。   The holding convex portions 13 and 13 are inclined inward with the outer end as a top portion 13a, and face the plate-like body B on the lower plate-like spacer 10 or the bottom portion 2. Even if it receives a load in a right angle direction, it comes into contact with the outer end portion of the peripheral portion having a slight width that does not interfere.

前記の突出縁部１２，１２は、図のように長辺側の両辺部の中央部に所要の長さでそれぞれ１つずつ設けるほか、該両辺部の長さ方向に間隔をおいて複数個所、例えば２個所に設けて実施することもできる。さらに、図示していないが、四周各辺部に前記同様の突出縁部を設けるとともに、これに対応する容器本体の四周各側壁の内面に前記突出縁部が嵌合する嵌合凹部を形成して、上記同様に実施することもできる。   As shown in the figure, each of the protruding edges 12 and 12 is provided at the center of both sides on the long side with a required length, and a plurality of protruding edges 12 and 12 are provided at intervals in the length direction of the both sides. For example, it can also be provided at two locations. Furthermore, although not shown in the drawing, the same protruding edges as those described above are provided on each side of the four circumferences, and fitting recesses are formed on the inner surfaces of the corresponding four side walls of the container body to fit the protruding edges. It can also be carried out in the same manner as described above.

さらに、図示する実施例の場合、板状スペーサ１０の短辺側の両辺部と、これに対応する容器本体１の短辺側の側壁４，４間の中央部に、板状体取り出し用の切欠部１５、７が設けられており、該切欠部１５、７の空間を利用して取り出し用の掛け具や作業者の手を差し込んで板状体Ｂを取り出せるようになっている。   Further, in the case of the illustrated embodiment, the plate-like body is taken out at both sides on the short side of the plate-like spacer 10 and the central part between the corresponding side walls 4 and 4 on the short side of the container body 1. Cutout portions 15 and 7 are provided, and the plate-like body B can be taken out by inserting a removal tool or an operator's hand using the space of the cutout portions 15 and 7.

なお、前記容器本体１の四周の側壁３，３；４，４の開口端部は、内側が切欠されて外側に凸縁８が形成され、また容器本体１の底部下面の外周部には、前記凸縁８に対応した切欠部９が形成されており、図９のように、板状体Ｂを収納した状態の搬送用容器Ａを、前記凸縁８と切欠部９を嵌合して安定性よく段積みできるようになっている。必要に応じて、容器本体１の開口端部に容器本体１と同様の合成樹脂発泡体により形成した蓋体（図示せず）を被せることもできる。   The open end of the four side walls 3, 3; 4, 4 of the container body 1 is notched on the inside to form a convex edge 8 on the outside, and on the outer periphery of the bottom lower surface of the container body 1, A notch 9 corresponding to the convex edge 8 is formed. As shown in FIG. 9, the transport container A in which the plate-like body B is accommodated is fitted into the convex edge 8 and the notch 9. Stackable with good stability. If necessary, a lid (not shown) formed of a synthetic resin foam similar to that of the container body 1 can be put on the opening end of the container body 1.

前記容器本体１及び板状スペーサ１０の構成材料としては、ポリスチレン、ハイインパクトポリスチレン、スチレン−エチレン共重合体、スチレン−無水マレイン酸共重合体、スチレン−アクリロニトリル共重合体等のポリスチレン系樹脂、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体等のポリオレフィン系樹脂、ポリ乳酸、ポリエチレンテレフタレート等のポリエステル系樹脂等の各種合成樹脂の発泡体を用いることができる。中でも、ポリスチレン系樹脂とポリオレフィン系樹脂を含む複合樹脂のビーズ発泡体による成形体が好適に用いられる。ポリスチレン系樹脂とポリオレフィン系樹脂を含む複合樹脂のビーズ発泡体は、ポリオレフィン系樹脂粒子にスチレン系単量体を重合させた後、発泡剤を含浸させた発泡性樹脂粒子を、蒸気加熱することにより成形体を得ることができる。   Constituent materials for the container body 1 and the plate-like spacer 10 include polystyrene, high impact polystyrene, polystyrene resins such as styrene-ethylene copolymer, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer, and polyethylene. , Foams of various synthetic resins such as polyolefin resins such as polypropylene and ethylene-vinyl acetate copolymer, and polyester resins such as polylactic acid and polyethylene terephthalate can be used. Especially, the molded object by the bead foam of the composite resin containing a polystyrene-type resin and a polyolefin-type resin is used suitably. A composite resin bead foam containing a polystyrene resin and a polyolefin resin is obtained by polymerizing a polyolefin resin particle with a styrene monomer and then steam-heating the expandable resin particles impregnated with a foaming agent. A molded body can be obtained.

上記した板状体の搬送用容器Ａによれば、素板ガラス、液晶表示用のガラス基板等の板状体Ｂを板状スペーサ１０を介在させて収納する。この際、各板状体Ｂの表裏面にフィルムや紙等の保護シートＣを重ねて保護した状態で収納する。例えば、容器本体１の底部２上に１枚の板状体Ｂを載置した後、板状スペーサ１０を保持用の凸部１３，１３の側を下面側にして、相対向辺部に設けた突出縁部１２，１２を容器本体１の相対向する側壁３，３に有する嵌合凹部６，６に嵌合して収納し、さらに該板状スペーサ１０の上に板状体Ｂを載置した後、前記同様に、板状スペーサ１０の突出縁部１２，１２を嵌合凹部６，６に嵌合して収納する。このようにして、板状体Ｂと板状スペーサ１０とを交互に重ねて収納し、図５及び図７のように積み重ねた状態にする。   According to the above-described container A for transporting a plate-like body, the plate-like body B such as a raw glass plate or a glass substrate for liquid crystal display is accommodated with the plate-like spacer 10 interposed therebetween. At this time, a protective sheet C such as a film or paper is stacked on the front and back surfaces of each plate B and stored in a protected state. For example, after placing a single plate-like body B on the bottom 2 of the container body 1, the plate-like spacer 10 is provided on the opposite sides with the holding projections 13, 13 side as the lower surface side. The protruding edges 12 and 12 are fitted into and accommodated in the fitting recesses 6 and 6 on the opposite side walls 3 and 3 of the container body 1, and the plate-like body B is mounted on the plate-like spacer 10. After the placement, the protruding edges 12 and 12 of the plate-like spacer 10 are fitted into the fitting recesses 6 and 6 and stored in the same manner as described above. In this way, the plate-like bodies B and the plate-like spacers 10 are alternately stacked and stored, and are stacked as shown in FIGS.

この収納状態においては、図５〜図８のように、各板状スペーサ１０は、突出縁部１２，１２が嵌合凹部６，６に嵌合することで、位置ずれなく重ねられるとともに、該突出縁部１２，１２の部分で積み重ね荷重を支え、各板状スペーサ１０のスペーサ本体部１１，１１間には、所定の間隙Ｓを保有することで、該間隙Ｓの部分で保持される板状体Ｂには、積み重ね荷重が負荷されることがない。   In this stored state, as shown in FIGS. 5 to 8, the plate-like spacers 10 are overlapped without being displaced by the protruding edges 12 and 12 being fitted into the fitting recesses 6 and 6, and The stacking load is supported by the protruding edge portions 12 and 12, and a predetermined gap S is provided between the spacer main body portions 11 and 11 of each plate-like spacer 10 so that the plate is held by the gap S portion. The stacked body B is not subjected to a stacking load.

しかも、前記板状スペーサ１０には、スペーサ本体部１１の下面の周縁部に保持用の凸部１３，１３が設けられており、前記の積み重ね状態においては、その下の底部２上及び板状スペーサ１０上に載置された板状体Ｂの周縁部とごく僅かなクリアランスを存して対向するか（図６、図８）、もしくは軽く接触して支持するように対向し、該板状体Ｂの浮き上がり等の動きを規制する役目を果たし、過度の荷重を負荷させることもない。そのため、輸送中の板状体Ｂの割れや破損を防止できる。特に、前記凸部１３が、板状体Ｂの面直角方向の荷重を受けても差し支えのない若干幅の周縁部の個所で、浮き上がりを規制するように支持できるので、板状体Ｂの保護を良好になすことができる。   In addition, the plate-like spacer 10 is provided with holding projections 13 and 13 on the peripheral edge of the lower surface of the spacer main body 11, and in the stacked state, on the bottom 2 below and on the plate-like spacer 10. It is opposed to the peripheral edge of the plate-like body B placed on the spacer 10 with very little clearance (FIGS. 6 and 8) or opposed so as to be supported in light contact with the plate-like body. It plays a role of regulating the movement of the body B, such as lifting, and does not apply an excessive load. Therefore, the crack or breakage of the plate-like body B during transportation can be prevented. In particular, since the convex portion 13 can be supported so as to restrict lifting at a portion of the peripheral portion having a slight width that does not interfere even when a load in a direction perpendicular to the surface of the plate-like body B is received, the plate-like body B is protected. Can be made well.

また板状スペーサ１０自体に積み重ね荷重を負荷させることがないため、板状体Ｂを保持するスペーサ本体部１１の精度を過度に高くする必要がなく、容器本体１と同素材の合成樹脂発泡体等による成形により容易にコスト安価に製作できることになる。   Further, since the stacking load is not applied to the plate-like spacer 10 itself, it is not necessary to excessively increase the accuracy of the spacer main body 11 that holds the plate-like body B, and the synthetic resin foam of the same material as the container main body 1 is used. It can be easily manufactured at a low cost by molding by means of, for example.

本発明の搬送用容器は、素板ガラス、液晶表示用やプラズマ表示用のガラス基板等の比較的大型のガラス基板、あるいはタッチセンサー、タッチパネル等の衝撃に弱いパネル等の各種の板状体を搬送、保管するのに好適に利用できる。   The transport container of the present invention transports various plate-like bodies such as a base plate glass, a relatively large glass substrate such as a glass substrate for liquid crystal display or plasma display, or a panel sensitive to impact such as a touch sensor or a touch panel. It can be suitably used for storage.
