Description

本発明は、コンテナ用蓋及びコンテナに関し、特に、金属片や金属粉を嫌う物品をコンテナに収容して搬送等をする場合に、そのコンテナの蓋として用いて好適なコンテナ用蓋、及び、金属片や金属粉を嫌う物品を収容して搬送等をするのに好適なコンテナに関する。 TECHNICAL FIELD The present invention relates to a container lid and a container, and more particularly to a container lid suitable for use as a container lid and a metal when an article that dislikes a metal piece or metal powder is accommodated in the container and transported. The present invention relates to a container suitable for accommodating and conveying articles that dislike pieces or metal powder.

近年、物流システムの進展あるいは物品の輸送環境の変化等により、種々雑多な様々な物品が汎用の組立て式コンテナに収容されて搬送あるいは保管されており、これに伴って様々な用途の様々な構成の様々な種類の組立て式コンテナが提供されている。この種のコンテナにおいては、通常、軽量で頑丈で安価なものが要望されるが、最近では、振動や揺れを大幅に吸収できる精密機器のコンテナや、微細なゴミや粉塵も排除した状態で物品を搬送できる半導体デバイス材料用のコンテナ等、耐振性能や防塵性能等の特定の特性に優れた高性能な組立て式コンテナも開発され利用されている（例えば特許文献１参照）。
特開２００７−２６９３７３号公報 In recent years, various miscellaneous and various articles have been housed and transported or stored in a general-purpose assembly-type container due to the development of the logistics system or changes in the transportation environment of articles, and various configurations for various applications have been associated with this. Various types of prefabricated containers are provided. This type of container is usually required to be lightweight, sturdy, and inexpensive, but recently, it is a container for precision equipment that can absorb vibrations and vibrations greatly, and it also eliminates fine dust and dust. A high-performance assembly-type container excellent in specific characteristics such as vibration resistance and dust-proof performance, such as a container for semiconductor device materials capable of transporting materials, has been developed and used (see, for example, Patent Document 1).
JP 2007-269373 A

このような環境の中で、金属片や金属粉あるいは金属面の露出等、金属を極端に嫌う物品等を組立て式の汎用コンテナに収容して搬送等をしたいという要望がある。例えば、太陽電池等の素子表面における電気化学反応や電気光学反応等の性質を利用する素子や、このような素子を用いたデバイスの製造に用いられるガラス基板等の部品においては、金属粉が付着することにより素子の特性が影響を受ける可能性があり、金属を排除した環境での搬送等が望まれている。また、通常の半導体素子等においても、パターンの微細化やチップの小型化が進むにつれて、微細な金属粒子や金属片の混入により回路やチップが影響を受ける可能性が高くなっており、これらも、極力金属を排除した環境での搬送等が望まれている。さらにはまた、燃料電池等は、金属が混入することにより化学反応が生じる場合があり、結果の重大性を考えると、金属が混入する可能性が絶対にあり得ないような状態での搬送が望まれている。 In such an environment, there is a demand for accommodating articles such as metal pieces, metal powder, or exposed metal surfaces in an assembling-type general-purpose container for transportation. For example, metal powder adheres to components that utilize properties such as electrochemical reactions and electro-optic reactions on the surface of elements such as solar cells and glass substrates used in the manufacture of devices using such elements. Therefore, there is a possibility that the characteristics of the element may be affected, and transport in an environment in which metal is excluded is desired. Also in ordinary semiconductor elements, etc., as patterns become finer and chips become smaller, there is a high possibility that circuits and chips will be affected by the mixing of fine metal particles and metal pieces. Therefore, transportation in an environment in which metal is eliminated as much as possible is desired. Furthermore, a fuel cell or the like may cause a chemical reaction due to metal contamination, and considering the seriousness of the result, transportation in a state where there is no possibility of metal contamination is possible. It is desired.

しかしながら、前述したようにこの種のコンテナにおいては、軽量で丈夫で安価なことが基本的な条件となっている。このような要望を達成するためには、面部材としてプラスチック製ダンボールや樹脂性の面材等の軽量な部材を使用することは非常に有効であるが、その一方で基本的な強度や耐久性を維持するために、枠部分には金属製の枠部材を使用することが必須となっている。従って、金属製の部材を使用せずに、軽量で頑丈で安価で、さらに耐振性や防塵性等の性能にも優れた組立て式コンテナを提供することは非常に困難である。 However, as described above, the basic condition for this type of container is that it is lightweight, strong and inexpensive. In order to achieve such a demand, it is very effective to use a lightweight member such as a plastic cardboard or a resinous face material as the face member, but on the other hand, the basic strength and durability. In order to maintain the above, it is essential to use a metal frame member for the frame portion. Therefore, it is very difficult to provide a prefabricated container that does not use a metal member and is lightweight, sturdy, inexpensive, and excellent in performance such as vibration resistance and dust resistance.

また、通常のこの種のコンテナは、コンテナ本体と、その上方の開口を閉塞する蓋とにより構成されるが、前述したように金属を排除した収容空間を形成しようとした場合、蓋に使用されている金属部材が非常に問題となる。蓋は収容空間の上方に装着されるために、仮に蓋に使用されている金属部材が離脱したり、あるいはまた蓋が金属粉等の発生源となった場合には、それらの金属部材や金属粉は直ちに収容空間に落下し、あるいは収容空間内を浮遊することとなり、収容物に対して直接に接触をすることとなるからである。 In addition, this type of normal container is composed of a container body and a lid that closes the opening above the container body. However, as described above, it is used for a lid when an accommodation space that excludes metal is formed. The metal member which becomes is a problem. Since the lid is mounted above the storage space, if the metal member used for the lid is detached or if the lid becomes a source of metal powder, the metal member or metal This is because the powder immediately falls into the storage space or floats in the storage space and comes into direct contact with the stored item.

また、蓋はコンテナ本体に対して付属的な部材であるために、通常、比較的簡易な構成とされており、また、利用者等から見ても比較的簡易な構成であることが期待されていると言える。しかしながら一方で、蓋を介してコンテナが積み重ねられる場合があることや、収容空間を規定し保護する最も重要なコンテナ上面を閉塞する部材であること等を考慮すると、蓋はコンテナ本体と同等かそれ以上の強度が要求される部材である。このような条件から、蓋においてこそ金枠等の金属部材や、金枠と面材を効率よく強固に一体化するビス、リベット、ボルト／ナット等の金属部品は不可欠なものである。そして、ビスやリベット等の部品を使用している限り、使用をしているうちに徐々に緩みが生じてそれらの部品が落下する可能性は排除できず、その結果、上述したように収容空間に金属部材が落下する可能性を限りなくゼロにすることが要望される用途においては使用できない。 In addition, since the lid is a member attached to the container body, the lid is usually a relatively simple configuration, and is expected to be a relatively simple configuration from the viewpoint of the user. It can be said that. However, on the other hand, considering that the containers may be stacked through the lid and the most important member that closes the top surface of the container that defines and protects the storage space, the lid is equivalent to the container body. It is a member that requires the above strength. Under such conditions, metal parts such as a metal frame and metal parts such as screws, rivets, and bolts / nuts that efficiently and firmly integrate the metal frame and the face material are indispensable for the lid. As long as parts such as screws and rivets are used, it is impossible to eliminate the possibility that these parts will gradually loosen and fall as they are used. Therefore, it cannot be used in applications where it is desired to eliminate the possibility of metal members falling to the limit.

本発明は、このような課題に鑑みてなされたものであって、金属を排除して収容することが要望される所望の物品を収容するのに好適なコンテナ及びそのような物品を収容したコンテナに使用して好適なコンテナ用蓋を提供することにある。
換言すれば、本発明の目的は、軽量で丈夫で安価でありながら、金属片や金属粉等の発生、金属面の露出が無く、金属部品が落下等する可能性を排除したコンテナ用蓋を提供すること、及び、軽量で丈夫で安価でありながら、金属片や金属粉等の発生、金属面の露出が無く、金属部品が落下等する可能性も無い状態で物品を収容することができるコンテナを提供することにある。 The present invention has been made in view of such a problem, and is a container suitable for housing a desired article that is desired to be accommodated by removing metal, and a container that accommodates such an article. It is in providing the lid | cover for containers suitable for using.
In other words, the object of the present invention is to provide a container lid that is light, strong and inexpensive, but has no occurrence of metal pieces or metal powder, exposure of the metal surface, and the possibility of metal parts falling.

本発明の一実施形態について、図１〜図９を参照して説明する。
本実施形態においては、本発明に係るコンテナ用蓋を有する組立て式コンテナの一具体例について説明する。本実施形態のコンテナは、任意の物を収容可能なコンテナであるが、特に、内部空間（収容空間）に対して金属の露出が無く、また、内部に金属が入ることを防止したコンテナであり、従って、金属が付着等すると好ましくない物品を収容し、搬送するのに好適なコンテナである。 An embodiment of the present invention will be described with reference to FIGS.
In the present embodiment, a specific example of an assembly type container having a container lid according to the present invention will be described. Although the container of this embodiment is a container which can accommodate arbitrary things, it is a container which has no metal exposure to the internal space (accommodation space) and prevents metal from entering inside. Therefore, it is a container suitable for accommodating and transporting an object which is not preferable when a metal adheres thereto.

図１は、そのコンテナ１の全体構成を示す分解斜視図である。
図１に示すように、コンテナ１は、パレット１０、下枠部材２０、床板３０、２枚の第１の側板４０、２枚の第２の側板５０及び蓋１００を有する。 FIG. 1 is an exploded perspective view showing the overall configuration of the container 1.
As shown in FIG. 1, the container 1 includes a pallet 10, a lower frame member 20, a floor plate 30, two first side plates 40, two second side plates 50, and a lid 100.

パレット１０は、コンテナ１の搬送台であり、その側面にはフォークリフトの爪部が差し込まれるリフト用孔１１が形成されている。本実施形態のコンテナ１において、パレット１０は樹脂製である。 The pallet 10 is a carrier for the container 1, and a lift hole 11 into which a forklift claw portion is inserted is formed on a side surface of the pallet 10. In the container 1 of the present embodiment, the pallet 10 is made of resin.

パレット１０の上部には、その周縁に沿って下枠部材２０が設置されている。
下枠部材２０は、断面Ｌ字形状の長尺部材を、パレット１０の上面の外周縁に沿って固定設置したものである。下枠部材２０は、直交する一方の板面がパレット１０上に設置され、他方の板面がパレット１０の外周縁に側壁状に立設するように設置される。 A lower frame member 20 is installed along the periphery of the upper portion of the pallet 10.
The lower frame member 20 is a long member having an L-shaped cross section fixedly installed along the outer peripheral edge of the upper surface of the pallet 10. The lower frame member 20 is installed such that one orthogonal plate surface is installed on the pallet 10 and the other plate surface is erected on the outer peripheral edge of the pallet 10 in a side wall shape.

下枠部材２０の各角部には、断面Ｌ形状のコーナー金具２１が設けられている。コーナー金具２１の、第１の側板４０の下に配設されることになる辺上の立側面の端部には、第１の側板４０の下角部に形成される係合ピン４３が挿入される係合孔２２が形成されている。
また、コーナー金具２１は、第１の側板４０、第２の側板５０及び蓋１００が折り畳まれてパレット１０上に載置された状態においては、折り畳まれたコンテナ１を順次積み重ねるための支柱となる。 A corner fitting 21 having an L-shaped cross section is provided at each corner of the lower frame member 20. An engaging pin 43 formed at the lower corner of the first side plate 40 is inserted into the end of the side surface of the corner metal 21 on the side to be disposed under the first side plate 40. An engagement hole 22 is formed.
In addition, the corner fitting 21 serves as a support for sequentially stacking the folded containers 1 in a state where the first side plate 40, the second side plate 50, and the lid 100 are folded and placed on the pallet 10. .

下枠部材２０の第１の側板４０の下に配設されることになる辺上の下面（パレット１０に設置されている面）には、第１の側板４０の下端面から突出している自立用ピン４４が挿入される嵌合孔２３が形成されている。 On the lower surface (the surface installed on the pallet 10) on the side to be disposed under the first side plate 40 of the lower frame member 20, a self-standing projecting from the lower end surface of the first side plate 40. The fitting hole 23 into which the use pin 44 is inserted is formed.

本実施形態において下枠部材２０は、鉄、ステンレス及びアルミニウム等の金属の表面に樹脂被膜をコーティングした部材を用いる。樹脂被膜は、いわゆるディッピングにより、より具体的には流動浸漬粉体コーティングにより行う。流動浸漬粉体コーティングは、コーティング対象物を加熱し、加熱した対象物を粉体樹脂を流動させた流動槽内にディッピング（浸漬）することにより対象物の表面に粉体状の樹脂を付着させ、さらに後加熱処理をすることにより強く、美しい塗膜を形成するものである。下枠部材２０を含む本実施形態のコンテナ１の各金属部材は、いずれもこの流動浸漬粉体コーティングを行ったものである。本実施形態においては、３〜４秒の浸漬により０．４〜０．８ｍｍの樹脂被膜を金属表面に形成する。
下枠部材２０は、このように構成された部材であり、従って、金属部材を用いることによる強度の維持ができる一方で、金属部材が表面に露出することは無い。 In the present embodiment, the lower frame member 20 is a member in which a resin film is coated on the surface of a metal such as iron, stainless steel, or aluminum. The resin coating is performed by so-called dipping, more specifically, fluidized immersion powder coating. Fluid immersion powder coating heats the coating object and dipped (immerses) the heated object in a fluidized tank in which the powder resin is flowed to attach the powdered resin to the surface of the object. Further, a strong and beautiful coating film is formed by further post-heating treatment. Each metal member of the container 1 of the present embodiment including the lower frame member 20 is obtained by performing this fluidized immersion powder coating. In this embodiment, a resin film having a thickness of 0.4 to 0.8 mm is formed on the metal surface by immersion for 3 to 4 seconds.
The lower frame member 20 is a member configured as described above. Therefore, while the strength can be maintained by using the metal member, the metal member is not exposed to the surface.

パレット１０上の第１の側板４０及び第２の側板５０で囲まれた範囲には、樹脂あるいはプラスチック製ダンボール等の非金属部材により構成される床板３０が載置される。 In a range surrounded by the first side plate 40 and the second side plate 50 on the pallet 10, the floor plate 30 made of a non-metallic member such as resin or plastic cardboard is placed.

パレット１０の上面の外周縁には、すなわち、下枠部材２０に沿った位置には、対向する２枚の第１の側板４０及び対向する２枚の第２の側板５０の計４枚の側板４０及び５０が着脱自在に装着される。４枚の側板４０及び５０は、それぞれ面部材４１及び５１と、その外周縁に設置される枠部材４２及び５２とにより構成される。 At the outer peripheral edge of the upper surface of the pallet 10, that is, at a position along the lower frame member 20, a total of four side plates of two opposing first side plates 40 and two opposing second side plates 50. 40 and 50 are detachably mounted. The four side plates 40 and 50 are respectively composed of surface members 41 and 51 and frame members 42 and 52 installed on the outer peripheral edge thereof.

第１の側板４０の枠部材４２の下角部であって、第１の側板４０をパレット１０上に設置した場合に外側となる面には、外向きに係合ピン４３が形成されている。また、第１の側板４０の枠部材４２の下端面には、例えば図示のごとく２箇所に自立用ピン４４が形成されている。
第１の側板４０をパレット１０の上面の外周縁に立設する場合には、自立用ピン４４を下枠部材２０に設けられた嵌合孔２３に挿入するとともに、係合ピン４３をコーナー金具２１の係合孔２２に挿入する。その結果、自立用ピン４４が嵌合孔２３に挿入されることにより第１の側板４０の下端辺の位置がパレット１０の周縁の下枠部材２０に沿った位置（下枠部材２０上）に規定され、また、係合ピン４３が係合孔２２と係合することにより、第１の側板４０の上方向への抜けが防止される。 Engagement pins 43 are formed outward on the lower corners of the frame member 42 of the first side plate 40 and on the outer surface when the first side plate 40 is placed on the pallet 10. In addition, on the lower end surface of the frame member 42 of the first side plate 40, for example, two self-supporting pins 44 are formed as shown in the drawing.
When the first side plate 40 is erected on the outer peripheral edge of the upper surface of the pallet 10, the self-standing pins 44 are inserted into the fitting holes 23 provided in the lower frame member 20, and the engaging pins 43 are connected to the corner fittings. 21 is inserted into the engagement hole 22. As a result, when the self-supporting pin 44 is inserted into the fitting hole 23, the position of the lower end side of the first side plate 40 is at a position along the lower frame member 20 at the periphery of the pallet 10 (on the lower frame member 20). Further, when the engagement pin 43 engages with the engagement hole 22, the first side plate 40 is prevented from coming off upward.

また、第１の側板４０の両側縁部においては、図示省略するが、枠部材４２に、内側方向に第２の側板５０を嵌入させるスライド溝が形成されている。従って、対向する２枚の第１の側板４０をパレット１０上の対辺上に立設した後、対向するスライド溝に第２の側板５０を差し込むことにより、２枚の第１の側板４０をその両端部で接続するように、対向する２枚の第２の側板５０が立設される。
第２の側板５０は、その上辺部に設けられた連結具５３により、隣接する第１の側板４０と上端部が連結される。 Further, on both side edges of the first side plate 40, although not shown in the drawing, a slide groove for fitting the second side plate 50 in the inner direction is formed in the frame member 42. Therefore, after the two opposing first side plates 40 are erected on the opposite side of the pallet 10, the second first side plate 40 is inserted into the opposing slide groove by inserting the second side plate 50 into the opposite slide groove. Two opposing second side plates 50 are erected so as to be connected at both ends.
The second side plate 50 is connected to the adjacent first side plate 40 and the upper end by a connector 53 provided on the upper side thereof.

このように各々２枚の第１の側板４０及び第２の側板５０の下縁の位置がパレット１０の周縁に規定され、第１の側板４０及び第２の側板５０が各々その上部で連係されることにより、これら各側板がパレット１０の周縁に立設される。そして、これにより、パレット１０上に、第１の側板４０及び第２の側板５０で周囲を囲まれた収容空間６０が形成される。 In this way, the positions of the lower edges of the two first side plates 40 and the second side plates 50 are defined on the periphery of the pallet 10, and the first side plate 40 and the second side plate 50 are linked together at the upper part thereof. As a result, these side plates are erected on the periphery of the pallet 10. As a result, an accommodation space 60 surrounded by the first side plate 40 and the second side plate 50 is formed on the pallet 10.

本実施形態において、第１の側板４０及び第２の側板５０の面部材４１及び５１は、ダンボールプラスチック等の非金属の板状部材が用いられる。
一方、枠部材４２及び５２、及び、これらに付設して形成される係合ピン４３、自立用ピン４４、及び、連結具５３は、下枠部材２０と同様に、鉄、ステンレスあるいはアルミニウム等の金属の表面に、ディッピング（流動浸漬粉体コーティング）により樹脂被膜をコーティングした部材を用いる。従って、第１の側板４０及び第２の側板５０においても、金属部材を用いることによる強度は維持できる一方で、表面に金属部材が表面に露出することは回避される。 In the present embodiment, the surface members 41 and 51 of the first side plate 40 and the second side plate 50 are non-metallic plate-like members such as cardboard plastic.
On the other hand, the frame members 42 and 52, and the engaging pins 43, the self-supporting pins 44, and the connecting members 53 attached thereto are made of iron, stainless steel, aluminum, or the like, like the lower frame member 20. A member having a metal surface coated with a resin film by dipping (fluid immersion powder coating) is used. Therefore, also in the 1st side plate 40 and the 2nd side plate 50, while the intensity | strength by using a metal member can be maintained, it is avoided that a metal member is exposed to the surface on the surface.

収容空間６０の上方開口を閉じるために、コンテナ１においては蓋１００が着脱自在に装着される。
以下、本発明に係る蓋１００の構成について、さらに図２〜図９を参照して詳細に説明する。 In order to close the upper opening of the accommodation space 60, a lid 100 is detachably attached to the container 1.
Hereinafter, the configuration of the lid 100 according to the present invention will be described in detail with reference to FIGS.

図２（Ａ）は、蓋１００の上面図であり、図２（Ｂ）は図２（Ａ）のＡにおける断面図である。
図２（Ａ）に示すように、蓋１００は、面部材１１０と枠部材１２０とを有する。 2A is a top view of the lid 100, and FIG. 2B is a cross-sectional view taken along A in FIG. 2A.
As illustrated in FIG. 2A, the lid 100 includes a surface member 110 and a frame member 120.

面部材１１０は、プラスチック製ダンボール等の中空プラスチック構造板により形成される板状部材であり、枠部材１２０の内側形状に略等しい外形を有し、枠部材１２０の内側に嵌合設置される。なお、面部材１１０の隣接する２つの角部であって、面部材１１０を枠部材１２０に設置した場合に後述する面材押え保持部１５１及び１５２により枠部材１２０に保持される角部には、図６等に示すような、面材押え保持部１５１及び１５２の係止支柱１５６を貫通させるための開口１１８が形成されている。 The face member 110 is a plate-like member formed of a hollow plastic structural plate such as a plastic cardboard, has an outer shape substantially equal to the inner shape of the frame member 120, and is fitted and installed inside the frame member 120. Note that two adjacent corners of the face member 110, which are held by the frame member 120 by the face material press holding parts 151 and 152 described later when the face member 110 is installed on the frame member 120, As shown in FIG. 6 and the like, an opening 118 for penetrating the locking struts 156 of the face material presser holding portions 151 and 152 is formed.

枠部材１２０は、第１の側板４０及び第２の側板５０の枠部材４２及び５２、あるいは、下枠部材２０等と同様に、鉄、ステンレスあるいはアルミニウム等の金属の表面に、ディッピング（流動浸漬粉体コーティング）により樹脂被膜をコーティングした部材で形成される。従って、蓋１００の枠部材１２０においても、金属部材を用いることによる強度は維持できる一方で、表面に金属部材が表面に露出することは防止される。 Similar to the frame members 42 and 52 of the first side plate 40 and the second side plate 50, or the lower frame member 20, the frame member 120 is dipped (flow-immersed) on the surface of a metal such as iron, stainless steel, or aluminum. It is formed of a member coated with a resin film by powder coating). Therefore, the frame member 120 of the lid 100 can maintain the strength by using the metal member, while preventing the metal member from being exposed to the surface.

図２（Ａ）及び図２（Ｂ）に示すように、枠部材１２０は、断面が凹形状の長尺部材、すなわち溝１２１が形成されたレール形態の部材を、コンテナ１の収容空間６０の上縁部の形状に合わせて辺縁１２２〜１２５からなる矩形形状に形成した部材であり、内側に面部材１１０が配設される。
枠部材１２０は、コンテナ１の本体に装着される際に溝１２１の開口側が下側、すなわち第１の側板４０及び第２の側板５０側となるように形成され、この溝１２１が第１の側板４０及び第２の側板５０の上縁側に嵌合され、これにより、蓋１００がコンテナ１の本体に装着され、コンテナ１の収容空間６０の上方開口が閉塞される。 As shown in FIGS. 2A and 2B, the frame member 120 is a long member having a concave cross section, that is, a rail-shaped member in which a groove 121 is formed, in the housing space 60 of the container 1. It is a member formed in the rectangular shape which consists of edge 122-125 according to the shape of an upper edge part, and the surface member 110 is arrange | positioned inside.
The frame member 120 is formed so that the opening side of the groove 121 is the lower side, that is, the first side plate 40 and the second side plate 50 side when the frame member 120 is attached to the main body of the container 1. The upper edge side of the side plate 40 and the second side plate 50 is fitted, whereby the lid 100 is attached to the main body of the container 1 and the upper opening of the accommodation space 60 of the container 1 is closed.

蓋１００においては、枠部材１２０の４本の辺縁の中の１の辺縁（図２（Ａ）においては辺縁１２２）から、この辺縁１２２に隣接する２本の辺縁１２３及び１２４に沿って面部材１１０をスライドさせて枠部材１２０の内部に嵌入する（以下、辺縁１２２を面部材嵌入側辺縁１２２と称する場合もある。）。そして、面部材１１０の先端面が辺縁１２２に対向する反対側の辺縁１２５に当接した状態において、面部材１１０の面部材嵌入側の端面、すなわち辺縁１２２側の端面は、ちょうど辺縁１２２の内側に配置される。このような位置、すなわち、面部材１１０が枠部材１２０の内側にちょうど配設された状態において、面部材１１０は枠部材１２０によって保持される。 In the lid 100, from one edge (the edge 122 in FIG. 2A) of the four edges of the frame member 120 to the two edges 123 and 124 adjacent to the edge 122. The surface member 110 is slid along the frame member 120 and inserted into the frame member 120 (hereinafter, the edge 122 may be referred to as the surface member insertion side edge 122). Then, in a state where the front end surface of the surface member 110 is in contact with the opposite edge 125 facing the edge 122, the end surface on the surface member insertion side of the surface member 110, that is, the end surface on the edge 122 side is exactly the side Located inside the edge 122. In such a position, that is, in a state where the surface member 110 is just disposed inside the frame member 120, the surface member 110 is held by the frame member 120.

枠部材１２０が面部材１１０を保持するために、換言すれば、面部材１１０を枠部材１２０に固定設置するために、枠部材１２０は、２箇所のコーナー面材挟持部１３１及び１３２、３箇所の側部面材挟持部１４１〜１４３及び２箇所の面材押え保持部１５１及び１５２を有する。
なお、コーナー面材挟持部１３１及び１３２、及び、側部面材挟持部１４１〜１４３は、本願の特許請求の範囲において言う第１の保持部に相当し、面材押え保持部１５１及び１５２が、本願の特許請求の範囲において言う第２の保持部に相当する。 In order for the frame member 120 to hold the face member 110, in other words, to fix and install the face member 110 to the frame member 120, the frame member 120 has two corner face material sandwiching portions 131 and 132, and three places. Side face material clamping parts 141 to 143 and two face material presser holding parts 151 and 152.
The corner face material sandwiching portions 131 and 132 and the side face material sandwiching portions 141 to 143 correspond to the first holding portion referred to in the claims of the present application, and the face material retainer holding portions 151 and 152 are the same. This corresponds to the second holding portion referred to in the claims of the present application.

コーナー面材挟持部１３１及び１３２は、面部材嵌入側辺縁１２２に対向する辺縁１２５の両側の角部（コーナー）、すなわち、面部材１１０を枠部材１２０に嵌入する時に最も奥側となる角部に各々配設され、嵌入された面部材１１０を保持する。
図３は、その一方のコーナー面材挟持部１３１を示す図であって、図２（Ａ）のＢの方向から見た斜視図である。
図３（Ａ）に示すように、コーナー面材挟持部１３１は、辺縁１２３と辺縁１２５とにより形成されるコーナーの内側面に設置された平行な２枚の直角三角形形状の板部材、すなわち上板１３４と下板１３５とを有する。上板１３４と下板１３５とは、その間隔が面部材１１０の厚みに略等しくなるように設置されており、辺縁１２３に沿って挿入されてきた面部材１１０の端部は、上板１３４と下板１３５との間に嵌入される。その結果、図３（Ｂ）に示すように、面部材１１０は、コーナー面材挟持部１３１により挟持される。すなわち、面部材１１０は、コーナー面材挟持部１３１の箇所において枠部材１２０に保持される。
なお、他方のコーナー面材挟持部１３２も、コーナー面材挟持部１３１と同じ構成、作用及び機能である。 The corner face material sandwiching portions 131 and 132 are corners (corners) on both sides of the edge 125 facing the face member insertion side edge 122, that is, the innermost side when the face member 110 is inserted into the frame member 120. Each surface member 110 is disposed at each corner and is fitted.
FIG. 3 is a view showing one corner face material sandwiching portion 131, and is a perspective view seen from the direction B in FIG. 2 (A).
As shown in FIG. 3A, the corner face material sandwiching portion 131 includes two parallel right-angled triangular plate members installed on the inner surface of the corner formed by the edge 123 and the edge 125, That is, it has an upper plate 134 and a lower plate 135. The upper plate 134 and the lower plate 135 are installed so that the distance between them is substantially equal to the thickness of the surface member 110, and the end of the surface member 110 inserted along the edge 123 is the upper plate 134. And the lower plate 135. As a result, as shown in FIG. 3B, the face member 110 is sandwiched by the corner face material sandwiching portion 131. That is, the face member 110 is held by the frame member 120 at the corner face material sandwiching portion 131.
The other corner face material sandwiching portion 132 also has the same configuration, function, and function as the corner face material sandwiching portion 131.

側部面材挟持部１４１〜１４３は、各々、面部材嵌入側辺縁１２２以外の辺縁１２３〜１２５の各々の略中央部に配設され、その箇所において嵌入された面部材１１０を保持する。
図４は、その一つの側部面材挟持部を示す図であって、面部材嵌入側辺縁１２２の対辺となる辺縁１２５の中央部に設置された側部面材挟持部１４２を示す図であり、図２（Ａ）のＣの方向から見た斜視図である。
図４（Ａ）に示すように、側部面材挟持部１４２は、辺縁１２５の中央部の内側面に設置された平行な２枚の板部材、すなわち上板１４４と下板１４５とを有する。上板１４４と下板１４５とは、その間隔が面部材１１０の厚みに略等しくなるように設置されており、辺縁１２５に当接するように挿入されてきた面部材１１０の縁端部は、上板１４４と下板１４５との間に嵌入される。その結果、図４（Ｂ）に示すように、面部材１１０は、側部面材挟持部１４１により挟持される。すなわち、面部材１１０は、側部面材挟持部１４２の箇所において枠部材１２０に保持される。
なお、その他の側部面材挟持部１４１及び１４３は、面部材１１０の挿入される方向が各々異なるものの、その構成及び作用・機能は同じである。 The side surface material sandwiching portions 141 to 143 are disposed at substantially the center of each of the edges 123 to 125 other than the surface member insertion side edge 122 and hold the surface member 110 inserted at that location. .
FIG. 4 is a view showing one of the side face material sandwiching portions, and shows the side face material sandwiching portion 142 installed at the center of the edge 125 which is the opposite side of the face member insertion side edge 122. It is a figure and is the perspective view seen from the direction of C of Drawing 2 (A).
As shown in FIG. 4A, the side surface material sandwiching portion 142 includes two parallel plate members, that is, an upper plate 144 and a lower plate 145 installed on the inner side surface of the central portion of the edge 125. Have. The upper plate 144 and the lower plate 145 are installed so that the distance between the upper plate 144 and the lower plate 145 is substantially equal to the thickness of the surface member 110, and the edge portion of the surface member 110 inserted so as to contact the edge 125 is It is inserted between the upper plate 144 and the lower plate 145. As a result, as shown in FIG. 4B, the face member 110 is sandwiched by the side face member sandwiching part 141. That is, the face member 110 is held by the frame member 120 at the side face material sandwiching portion 142.
The other side surface material sandwiching portions 141 and 143 have the same configuration, function, and function, although the direction in which the surface member 110 is inserted is different.

面材押え保持部１５１及び１５２は、図２（Ａ）に示すように、面部材嵌入側辺縁１２２の両側の角部に各々配設される部材であって、面部材１１０を枠部材１２０に設置した後においては、コーナー面材挟持部１３１及び１３２と同様にコーナーにおいて面部材１１０を挟持する。しかしながら面材押え保持部１５１及び１５２は、面部材１１０を枠部材１２０に嵌入する段階においては、上板に相当する部材が面部材１１０の嵌入進路を妨害しない位置（面部材１１０に干渉しない位置）に配置されており、面部材１１０を枠部材１２０に嵌入した後に、これを変形させて面部材１１０の押え部材、換言すれば面部材１１０の挟持部材として配設される構成となっている。
以下、面材押え保持部１５１及び１５２の構成について詳細に説明する。 As shown in FIG. 2A, the face material presser holding parts 151 and 152 are members respectively disposed at the corners on both sides of the face member insertion side edge 122, and the face member 110 is replaced with the frame member 120. After the installation, the surface member 110 is sandwiched at the corner in the same manner as the corner surface material sandwiching portions 131 and 132. However, at the stage where the face member 110 is inserted into the frame member 120, the face material presser holding portions 151 and 152 are located at positions where the member corresponding to the upper plate does not interfere with the insertion path of the face member 110 (position not interfering with the face member 110). After the surface member 110 is fitted into the frame member 120, the surface member 110 is deformed to be disposed as a pressing member for the surface member 110, in other words, as a holding member for the surface member 110. .
Hereinafter, the configuration of the face material presser holding portions 151 and 152 will be described in detail.

図５は、面材押え保持部１５１の構成を示す枠部材１２０の一部断面図であって、図５（Ａ）は、図２（Ａ）のＤの位置及び方向における、面部材１１０を枠部材１２０に装着する前の枠部材１２０の断面図であり、図５（Ｂ）は、図２（Ａ）のＥの位置及び方向における、面部材１１０を枠部材１２０に装着する前の枠部材１２０の断面図であり、図５（Ｃ）は、図２（Ａ）のＤの位置及び方向における面部材１１０を枠部材１２０に設置した後の枠部材１２０、すなわち蓋１００の断面図である。
また、図６〜図９は、面部材１１０を枠部材１２０に設置する蓋１００の組立て工程を示す図である。 FIG. 5 is a partial cross-sectional view of the frame member 120 showing the configuration of the face material presser holding portion 151. FIG. 5A shows the face member 110 at the position and direction D in FIG. FIG. 5B is a cross-sectional view of the frame member 120 before being attached to the frame member 120, and FIG. 5B is a frame before the surface member 110 is attached to the frame member 120 at the position and direction E in FIG. 5C is a cross-sectional view of the member 120, and FIG. 5C is a cross-sectional view of the frame member 120 after the surface member 110 is placed on the frame member 120 in the position and direction of D in FIG. is there.
6 to 9 are diagrams showing an assembly process of the lid 100 in which the surface member 110 is installed on the frame member 120.

図５（Ａ）、図５（Ｂ）及び図６に示すように、面材押え保持部１５１は、押え板１５４、下板１５５、係止支柱１５６を有する。
面材押え保持部１５１は、面部材１１０が枠部材１２０に設置された後は、図３を参照して前述したコーナー面材挟持部１３１の上板１３４に相当する構成であるが、面部材１１０を枠部材１２０に装着する（嵌入する）前においては、図示のごとく、枠部材１２０の上方に、すなわち下板１５５に対して垂直に立設された状態となっている。これにより、下板１５５の上部空間は開放された状態となり、枠部材１２０に嵌入する際に面部材１１０がここを通過することが可能になるとともに、枠部材１２０が面部材１１０の所定位置に配置された際には、下板１５５に対しては上方から面部材１１０を載置することができる。 As shown in FIGS. 5A, 5B, and 6, the face material presser holding portion 151 includes a presser plate 154, a lower plate 155, and a locking column 156.
The face material presser holding portion 151 is configured to correspond to the upper plate 134 of the corner face material sandwiching portion 131 described above with reference to FIG. 3 after the face member 110 is installed on the frame member 120. Before 110 is attached to (inserted into) the frame member 120, as shown in the figure, the frame 110 is erected above the frame member 120, that is, vertically to the lower plate 155. As a result, the upper space of the lower plate 155 is opened, and the surface member 110 can pass therethrough when being fitted into the frame member 120, and the frame member 120 is placed at a predetermined position of the surface member 110. When placed, the surface member 110 can be placed on the lower plate 155 from above.

押え板１５４は、面部材１１０が枠部材１２０に嵌合装着された後に面部材１１０の上面に折り曲げられるが、その際、折り曲げが適切な箇所で容易に行われるように、押え板１５４には、破線状に開孔１５７が形成されている（図５（Ｂ）参照）。強度を確保しつつ折り曲げを適切かつ容易に行うために、例えば押え板１５４の厚さは０．５〜３．０ｍｍ程度とするのが好ましく、その場合、開孔１５７の穴径φは１〜５ｍｍ、各開孔のピッチは２〜１５ｍｍとするのが好ましい。 The presser plate 154 is bent on the upper surface of the surface member 110 after the surface member 110 is fitted and attached to the frame member 120. At this time, the presser plate 154 includes a presser plate 154 so that bending can be easily performed at an appropriate place. An opening 157 is formed in a broken line shape (see FIG. 5B). In order to perform the bending appropriately and easily while ensuring the strength, for example, the thickness of the holding plate 154 is preferably about 0.5 to 3.0 mm. In that case, the hole diameter φ of the opening 157 is 1 to 1. 5 mm and the pitch of each aperture is preferably 2 to 15 mm.

また、押え板１５４の中央部には、押え板１５４を下板１５５の上部に折り曲げた時に下板１５５に設置されている係止支柱１５６が貫通される開口１５８が形成されている。 In addition, an opening 158 is formed at the center of the presser plate 154 through which the locking column 156 installed on the lower plate 155 passes when the presser plate 154 is bent to the upper part of the lower plate 155.

下板１５５は、枠部材１２０の内側に嵌合設置される面部材１１０を支持するとともに、押え板１５４が折り曲げられた後には、上板となる押え板１５４とともに面部材１１０を挟持する。 The lower plate 155 supports the surface member 110 fitted and installed inside the frame member 120, and holds the surface member 110 together with the pressing plate 154 serving as the upper plate after the pressing plate 154 is bent.

係止支柱１５６は、下板１５５の略中央部に図示のごとく立設された支柱であり、その上部には、差込部材１６０を嵌入させるための開口１５９が形成されている。係止支柱１５６の高さは、枠部材１２０の辺縁（例えば辺縁１２２、１２３）と略同じ高さであり、開口１５９の高さは、図５（Ｃ）に示すように、面部材１１０及び押え板１５４を下板１５５上に重ね置いた場合の高さと略同じ高さである。 The locking column 156 is a column erected as shown in the approximate center of the lower plate 155, and an opening 159 for inserting the insertion member 160 is formed in the upper portion. The height of the locking column 156 is substantially the same as the edge of the frame member 120 (for example, the edges 122 and 123), and the height of the opening 159 is a surface member as shown in FIG. 110 and the presser plate 154 are approximately the same height as when the upper plate 155 is placed on the lower plate 155.

このような面材押え保持部１５１においては、図５（Ａ）、図５（Ｂ）及び図６に示すように、押え板１５４が下板１５５に対して垂直に立設されている状態で、面部材１１０が面部材嵌入側辺縁１２２から、辺縁１２３及び１２４に沿って枠部材１２０の内側に差し込まれる。 In such a face material presser holding portion 151, as shown in FIGS. 5A, 5B, and 6, the presser plate 154 is erected vertically with respect to the lower plate 155. The surface member 110 is inserted from the surface member insertion side edge 122 into the frame member 120 along the edges 123 and 124.

その際、面部材１１０の先端部が辺縁１２３及び１２４の中央部に設置されている側部面材挟持部１４１及び１４２に達した時には、図４を参照して前述したように面部材１１０を側部面材挟持部１４１及び１４２の上板と下板（例えば、側部面材挟持部１４１の上板１４４と下板１４５）との間に嵌入し、さらに面部材１１０を辺縁１２５方向に差し込む。 At that time, when the front end portion of the surface member 110 reaches the side surface material sandwiching portions 141 and 142 installed at the central portions of the edges 123 and 124, as described above with reference to FIG. Is inserted between the upper plate and the lower plate (for example, the upper plate 144 and the lower plate 145) of the side surface material sandwiching portion 141, and the surface member 110 is connected to the edge 125. Insert in the direction.

面部材１１０の先端部が面部材嵌入側辺縁１２２の対辺となる辺縁１２５に達した時には、図３あるいは図４を参照して前述したように、辺縁１２５の両側のコーナー面材挟持部１３１及び１３２、及び、辺縁１２５の中央部の側部面材挟持部１４３の全てにおいて、面部材１１０がそれらの上板と下板（例えば、コーナー面材挟持部１３１の上板１３４及び上板１３４）との間に嵌入される。
その結果、枠部材１２０の辺縁１２３〜１２５に設けられている２箇所のコーナー面材挟持部１３１及び１３２、及び、３箇所の側部面材挟持部１４１〜１４３の各箇所においては、図３（Ｂ）あるいは図４（Ｂ）に示すような形態で、面部材１１０は枠部材１２０に挟持される。 When the front end of the face member 110 reaches the edge 125 that is the opposite side of the face member insertion side edge 122, as described above with reference to FIG. In all of the portions 131 and 132 and the side surface material sandwiching portion 143 at the center of the edge 125, the surface member 110 has an upper plate and a lower plate (for example, the upper plate 134 and the corner surface material sandwiching portion 131). It is inserted between the upper plate 134).
As a result, in each of the two corner face material sandwiching portions 131 and 132 provided on the edges 123 to 125 of the frame member 120 and the three side face material sandwiching portions 141 to 143, The surface member 110 is sandwiched between the frame members 120 in the form shown in FIG. 3B or FIG.

なお、このように面部材１１０を枠部材１２０に対して差し込む工程においては、面部材１１０の面部材嵌入側辺縁１２２上方を通過する部分は、少なくとも面部材嵌入側辺縁１２２の高さ分だけ、既に枠部材１２０の内部に差し込まれて各挟持部に挟持されている箇所よりも高い位置を通過することとなり、その結果、面部材１１０は上方に湾曲した形態となる。しかしながら、この湾曲の程度はごくわずかであり、面部材１１０が通常有する硬さでも十分に対応できるものである。換言すれば、面部材１１０が通常有する柔軟性の範囲で若干面部材１１０を反らせることにより、面部材１１０は、枠部材１２０の内側に差し込むことができる。 In the step of inserting the surface member 110 into the frame member 120 in this way, the portion of the surface member 110 that passes above the surface member insertion side edge 122 is at least the height of the surface member insertion side edge 122. As a result, it passes through a position higher than the portion already inserted into the frame member 120 and clamped by the clamping portions, and as a result, the surface member 110 is curved upward. However, the degree of this curvature is negligible, and the hardness that the surface member 110 normally has can be sufficiently accommodated. In other words, the surface member 110 can be inserted inside the frame member 120 by slightly warping the surface member 110 within the range of flexibility that the surface member 110 normally has.

面部材１１０を枠部材１２０に差し込んでその先端部が辺縁１２５に達した状態となると、面部材１１０の面部材嵌入側辺縁１２２側の縁端部は、面部材嵌入側辺縁１２２の内側の位置となり、面部材１１０はちょうど枠部材１２０の内側に嵌合される状態となる。
なお、前述したように、また図６に示すように、面部材１１０の面部材嵌入側辺縁１２２側となる角部には、面材押え保持部１５１及び１５２の係止支柱１５６を貫通させるための開口１１８が形成されている。従って、面部材１１０のこの角部を面材押え保持部１５１及び１５２の下板１５５上に載置する時には、図７に示すように、この開口１１８に下板１５５の係止支柱１５６が貫通された状態となる。 When the surface member 110 is inserted into the frame member 120 and the tip thereof reaches the edge 125, the edge of the surface member 110 on the surface member insertion side edge 122 side is the edge of the surface member insertion side edge 122. It becomes an inner position, and the surface member 110 is just fitted inside the frame member 120.
As described above and as shown in FIG. 6, the locking struts 156 of the face material presser holding portions 151 and 152 are made to penetrate the corner portions of the face member 110 on the side member insertion side edge 122 side. An opening 118 is formed. Therefore, when the corner portion of the face member 110 is placed on the lower plate 155 of the face material presser holding portions 151 and 152, the locking strut 156 of the lower plate 155 penetrates the opening 118 as shown in FIG. It will be in the state.

この状態において、面部材嵌入側辺縁１２２の両側の面材押え保持部１５１及び１５２の押え板１５４を、折り込み線たる破線（開孔）１５７に沿って内側に折り込み、その上部板面を下板１５５及び面部材１１０の上部に重ね合わせた状態とする。この時、押え板１５４に形成された開口１５８には、面部材１１０を介して下板１５５の係止支柱１５６の上部が貫通し、図８及び図５（Ｃ）に示すような状態となる。 In this state, the presser plates 154 of the face material presser holding portions 151 and 152 on both sides of the face member insertion side edge 122 are folded inward along a broken line (opening) 157 that is a folding line, and the upper plate surface is lowered. The plate 155 and the surface member 110 are superposed on each other. At this time, the upper portion of the locking column 156 of the lower plate 155 passes through the opening 158 formed in the holding plate 154 through the surface member 110, and the state shown in FIGS. 8 and 5C is obtained. .

そして、面部材１１０及び押え板１５４を貫通した係止支柱１５６の開口１５９に、長手方向の断面が楔形に形成された差込部材１６０を、図８に示すように差し込む。その結果、面材押え保持部１５１は、図９に示すように、面部材１１０の角部が押え板１５４と下板１５５との間に挟持された状態となる。その結果、比較的容易に折り込み可能であったために比較的容易に形状が元に戻る可能性のある押え板１５４も、係止支柱１５６に係合された差込部材１６０により上方より下板方向に押圧されるので、浮き上がる等の変形が防止される。従って、面材押え保持部１５１において、面部材１１０の保持状態が緩むことは無い。 Then, as shown in FIG. 8, the insertion member 160 whose longitudinal section is formed in a wedge shape is inserted into the opening 159 of the locking column 156 penetrating the surface member 110 and the pressing plate 154. As a result, as shown in FIG. 9, the face material press holding portion 151 is in a state where the corner portion of the face member 110 is sandwiched between the press plate 154 and the lower plate 155. As a result, the presser plate 154 whose shape can be returned to its original shape relatively easily because it can be folded relatively easily is also provided in the lower plate direction from above by the insertion member 160 engaged with the locking column 156. Therefore, deformation such as lifting is prevented. Therefore, the holding state of the face member 110 is not loosened in the face material press holding portion 151.

このようにして、面部材１１０は、枠部材１２０の内側の全周にわたって形成されたコーナー面材挟持部１３１、１３２、側部面材挟持部１４１〜１４３、及び、面材押え保持部１５１、１５２により挟持され、枠部材１２０とともに蓋１００として形成される。 Thus, the face member 110 includes corner face material sandwiching portions 131 and 132, side face material sandwiching portions 141 to 143 formed over the entire inner periphery of the frame member 120, and a face material retainer holding portion 151. 152 is formed as a lid 100 together with the frame member 120.

このような構成の蓋１００において、枠部材１２０、及び、枠部材１２０に設置されるコーナー面材挟持部１３１、１３２、側部面材挟持部１４１〜１４３、面材押え保持部１５１、１５２、さらには、これら各部材に形成されるピンや金具等の全て部材は、金属部材にディッピング（流動浸漬粉体コーティング）により樹脂被膜をコーティングした部材を用いる。従って、各部材ともに、金属部材を用いることによる強度は維持できる一方で、表面に金属部材が表面に露出することが防止される。 In the lid 100 having such a configuration, the frame member 120, the corner face material sandwiching portions 131 and 132 installed on the frame member 120, the side face material sandwiching portions 141 to 143, the face material press holding portions 151 and 152, Furthermore, all members such as pins and metal fittings formed on these members are members in which a metal film is coated with a resin film by dipping (fluid immersion powder coating). Therefore, each member can maintain the strength by using the metal member, while preventing the metal member from being exposed to the surface.

また、このような構成の蓋１００においては、前述の説明からもわかるように、ビス、リベット、ボルトあるいはナット等の着脱可能な金属部材は一切使用していない。金属部材は、枠部材１２０と、これに溶接等により一体的に形成された構成のみであり、実質的に１の部材で構成されているものである。ビスやリベット等の部品を使用している限り、使用をしているうちに徐々に緩みが生じてそれらの部品が落下する可能性は排除できないが、そのような部材を一切使用していない本実施形態のコンテナ用の蓋１００においては、収容空間に金属部材が落下する可能性は全く無く、そのような状態を回避したい物品の収容を適切に行うことができる。 In addition, as can be understood from the above description, the lid 100 having such a configuration does not use any removable metal member such as a screw, a rivet, a bolt, or a nut. The metal member is only configured to be integrally formed with the frame member 120 by welding or the like, and is substantially composed of one member. As long as parts such as screws and rivets are used, it is impossible to exclude the possibility that the parts will gradually loosen and fall as they are used. In the container lid 100 according to the embodiment, there is no possibility that the metal member will fall into the accommodation space, and it is possible to appropriately accommodate an article for which such a state is to be avoided.

このように、本実施形態のコンテナ１においては、下枠部材２０、第１の側板４０や第２の側板５０の各枠部材４２、蓋１００の枠部材１２０、あるいは、これら各部材に形成されるピンや金具等の全ての金属部材が、鉄、ステンレスあるいはアルミニウム等の金属の表面に、ディッピング（流動浸漬粉体コーティング）により樹脂被膜をコーティングした部材を用いている。また、側板や天板等の面部材は、全てプラスチック製ダンボール等の樹脂面材を使用しており、同じく金属面が露出することは無い。さらには、蓋１００には、ビス、リベット、ボルトあるいはナット等の着脱可能な金属部材は一切使用していない。 Thus, in the container 1 of the present embodiment, the lower frame member 20, the frame members 42 of the first side plate 40 and the second side plate 50, the frame member 120 of the lid 100, or these members are formed. All the metal members such as pins and metal fittings used are members in which a resin film is coated on the surface of a metal such as iron, stainless steel or aluminum by dipping (fluid immersion powder coating). Further, all the surface members such as the side plate and the top plate are made of resin surface material such as plastic corrugated cardboard, and the metal surface is not exposed. Furthermore, the lid 100 does not use any removable metal member such as screws, rivets, bolts or nuts.

従って、軽量で丈夫で安価でありながら、金属片や金属粉等の発生、金属面の露出が無く、金属部品が落下等する可能性も無い状態で物品を収容することができるコンテナ、すなわち、金属を排除して収容することが要望される所望の物品を収容するのに好適なコンテナを提供することができる。 Therefore, a container that can store articles in a state that is light, strong, and inexpensive, but does not generate metal pieces, metal powder, and the like, does not expose the metal surface, and has no possibility of falling metal parts, that is, It is possible to provide a container suitable for containing a desired article that is required to be stored without metal.

なお、本発明は、上述した実施形態に限定されるものではなく、本発明の範囲内で種々に改変することができる。
例えば、蓋１００の枠部材１２０における面部材１１０の保持構造等の細部は、前述した実施形態に限られるものではなく適宜任意の構造でよい。 The present invention is not limited to the above-described embodiment, and can be variously modified within the scope of the present invention.
For example, details such as the holding structure of the surface member 110 in the frame member 120 of the lid 100 are not limited to the above-described embodiment, and may be an arbitrary structure as appropriate.
