Description

【0001】
【発明の属する技術分野】
本発明は、落とし蓋で荷物を押し付けて固定するようにした運搬箱に関する。
【0002】
【従来の技術】
従来、図9に示したように落とし蓋たるハンモック部材101bで荷物を押し付け、その落とし蓋の浮き上がりを外に被せる蓋104で押さえるようにした運搬箱100がある。
【0003】
【発明が解決しようとする課題】
上記従来の運搬箱100は、落とし蓋の浮き上がりを外に被せる蓋104で押さえるようにしていたため、落とし蓋を片手で押さえながら蓋104を被せる必要があって作業性が悪い問題点があった。
【0004】
【課題を解決するための手段】
底板の周囲を側板で囲った箱と、箱に入れた荷物を上から押さえ付ける落とし蓋と、落とし蓋で荷物を押さえた反動でその落とし蓋に上向きの力を作用させる蓋付勢手段とを有し、前記箱の側板は、自己の上縁にモール部材を取り付けてそのモール部材の側板の内面に被さる部分の下縁を係合段部とし、一方、前記落とし蓋は、フレーム板の対向する2辺に折曲自在な側枠を連設し、前記蓋付勢手段による上向きの力に対し前記側枠上縁を前記係合段部の下に引っ掛かけて突張り状態で対抗し、また、前記蓋付勢手段による上向きの力に抗して側枠を押し下げることにより前記係合段部との係合を解きその状態で側枠を内側に倒して箱から抜き出し得るようにしたものである運搬箱を提供する。
【0005】
この運搬箱は、荷物を押さえた反動で落とし蓋が持ち上げられる力を利用し、落とし蓋の側枠上縁と係合段部を係合させて落とし蓋をロックするようにしたため、外に被せる蓋で落とし蓋の浮き上がりを押さえる従来構造に比べて荷物の設置が楽に行える。
【0006】
【発明の実施の形態】
以下に本発明の実施の形態を図1の分解斜視図を参照しつつ説明する。図1において、1は箱、2aはハンモック部材、2bは落とし蓋たるハンモック部材、Wは荷物である。箱1は四角い底板3の周囲に側板4を立ち上げ、さらに一つの側板4の上縁に蓋5を連設したものである。箱1の材質は、厚紙、段ボール紙、プラスチック段ボールなど、どのようなものであってもよいが、荷物Wが静電気の影響を受けるおそれがある場合には導電性を有するプラスチック段ボールを使用するのがよい。
【0007】
二つのハンモック部材2a,2bは、同一構造のものを上下に向きを違えて使用するものであるため、下のハンモック部材2aのみについて説明し、上のハンモック部材2bについては下のハンモック部材2aと同一の符号を付して説明を省略する。
【0008】
ハンモック部材2aは、窓孔7を有する四角い額縁状のフレーム8と、フレーム8外周に巻き掛けるエンドレスなベルト状(スリーブ状)であって蓋付勢手段たる弾性シート9と、前記フレーム8を箱1の内部の中間位置に止める支枠10の三部材で構成される。
【0009】
前記フレーム8は、箱1と同じ材料を使用してもよいが、好ましくは強度に優れるプラスチック段ボールがよい。フレーム8は、箱1の内側にほぼ合致する(又は一回り小さい)形状の例えば四角形であり、大きい窓孔7を打ち抜いた額縁状である。もちろんフレーム8の形状は箱1の形状に合わせて変更可能であり、また、窓孔7の形状も四角に限定されない。
【0010】
前記弾性シート9は、エンドレスなベルト状の形態であり、前記フレーム8の外周にフィットする形状に作られている。弾性シート9はベルト状の他、ベルトの一方の開口縁を塞いだ袋状にしてもよい。むしろ弾性シート9を袋状にした方がフレーム8上で弾性シート9がずれ難くなる分使い勝手がよい。弾性シート9の材質は、ポリウレタン系熱可塑性エラストマー、ポリアミド、天然ゴム、合成ゴム、ポリエチレンなど、ハンモック包装に適用可能なものなら何でもよい。また、荷物Wが静電気による悪影響を受けないように、弾性シート9に金属粉末やカーボン粉末などの導電性物質や、帯電防止剤を練り込むようにしてもよい。さらにまた弾性シート9の形態は面状に限らず、網状のものや気体を密封した独立気泡体を合成樹脂フィルムに多数形成してなる気泡シート構造でもよい。
【0011】
前記支枠10は、箱1の側板4の内側に沿う側枠11と、その側枠11の上縁に設置したフレーム板12で構成される。フレーム板12の形状は、前記フレーム8とほぼ同形であり、フレーム8の窓孔7に対応する大きな開口13が設けられている。支枠10の高さ、すなわち側枠11の高さは箱1の側板4の1/2弱であり、上下に積み重ねた側枠11,11の和が箱1の側板4の高さより僅かに小さくなるように設定されている。
【0012】
なお、図示を省略するが箱1の側板4には、上のハンモック部材2bの側枠11,11の上縁に係合してその上動を阻止する突起状の係合段部が設けられている。
【0013】
次に本発明の運搬箱の使用方法について説明する。先ず図1矢示Bのように弾性シート9の中にフレーム8を入れ込んでフレーム8外周に弾性シート9を巻き掛けた状態にしておく。次に、箱1の中にハンモック部材2aの支枠10をセットし、その上に弾性シート9付きのフレーム8を載せる。次に、ハンモック部材2aの弾性シート9中央に荷物Wを載せ、その上に弾性シート9付きのフレーム8と支枠10とからなる落とし蓋たるハンモック部材2bを載せ、さらにその上に蓋5を被せる。そうすると従来技術の図9(b)と同様に、両ハンモック部材2a,2bの弾性シート9,9間に荷物Wが挟まって動かないように保持される。
【0014】
なお、弾性シート9はエンドレスなベルト状又は袋状であってフレーム8の窓孔7部分では2重になっているから、弾性シート9の強度を従来より高めることができる。また、弾性シート9の張り具合は、弾性シート9の寸法を変更することで簡単に調整可能である。すなわち、弾性シート9をフレーム8にフィットする寸法にすると張りが強くなり、弾性シート9をルーズな寸法にすると張りが緩くなる。これにより荷物Wを強く圧迫し過ぎるトラブルや、逆に圧迫力が弱すぎて荷物Wの固定が不安定になるトラブルも防止できる。
【0015】
【実施例】
以下に本発明のより具体的な実施例を図2〜図8により説明する。なお、図2は使用状態を示す斜視図、図3は折り畳んだ箱を示す斜視図、図4は図2のA−A線端面図、図5(a),(b)は折り畳んだ状態を示すハンモック部材の斜視図、図6(a),(b)は組立状態を示すハンモック部材の斜視図、図7はフレームと弾性シートの分解斜視図、図8は下のハンモック部材の組立途中を示す裏側から見た斜視図である。
【0016】
【箱】
箱1は、本出願人の特開平10−119965号のものがベースになっている。すなわち箱1は、プラスチック段ボールを使った折り畳み自在構造であって、四角形の底板3の四辺に周壁を構成する側板4a〜4dを配設し、向かい合う二つの側板4a,4cをその上縁を中心にして内向きに揺動自在となし、残る二つの側板4b,4dを中央の折曲線14を中心にして屏風折り自在とし、そのような側板4a〜4dの組合せにより図3のごとく扁平な状態に折り畳み得る。
【0017】
なお、プラスチック段ボールは、図2の一部拡大図に示したように約0.4mm程度の板厚である合成樹脂(ポリプロピレン)製の二枚の基板15a,15bの間に段ボール紙の波芯に相当する仕切板15cを多数連設した形態であって、全体が約5mm程度の厚さである。前記側板4a〜4dの各ヒンジ部(折曲線14や側板4a,4cの上縁)は、プラスチック段ボールの基板15a(又は基板15b)を一枚だけ残して切込線を入れ(以下このような切込線をハーフカットという。)、その残った一枚の基板15a(又は基板15b)を曲げ伸ばしするようにしたものである。
【0018】
前記側板4a〜4dの上縁には合成樹脂製のモール部材16a〜16dが嵌着されている。側板4a〜4cの上縁に設けたモール部材16a〜16cは、断面下向きコ字状の公知構造であって、下向きに開口する溝に側板4a〜4cが嵌っている。また、側板4dの上縁に設けたモール部材16dは、図4に示したように、H型になっている。
【0019】
モール部材16a〜16d同士は四つのコーナー部材17,17…によって四角く連結されている。各コーナー部材17は合成樹脂の一体成型品であって、L字型の水平板17aと、該水平板17aの両側縁から下向きに垂設した二片のクランプ板17b,17bと、水平板17aの外側縁に上向きに突設した囲い枠17cとからなる。二片のクランプ板17b,17bは、前記モール部材16a〜16dの外側に跨る間隔と高さを有する。
【0020】
モール部材16dの上向きの溝には蓋5が取り付いている。この蓋5は、四つのコーナー部材17,17…の囲い枠17cに内接するような長方形より若干小さくした四角い蓋板5aと、該蓋板5aの一側縁にV字形ハーフカットのヒンジ部5bを介して連設した固定片5cと、その固定片5cと対向する側の端縁に設けた引掛片5dとからなり、固定片5がモール部材16dの前記上向きの溝に嵌め込まれている。
【0021】
【ハンモック部材】
上に位置するハンモック部材2bは本発明の落とし蓋であって、プラスチック段ボール製のフレーム8と、蓋付勢手段たる袋状にした弾性シート9と、プラスチック段ボール製の支枠10で構成される。支枠10は、フレーム板12と、そのフレーム板12の対向する2辺に連設した2枚の側枠11とからなり、フレーム板12と側枠11は、ハーフカットのヒンジ部18で折曲自在に繋がっている。従ってハンモック部材2bは、図5(a)(※図5(a)は図6(a)を裏返した状態に描いてある。)のようにフレーム板12に側枠11を重ねて扁平に折り畳み得る。なお、側枠11は強度を高めるために2枚重ねに形成され、また、側枠11の折り曲げの自由度を高めるためにハーフカットのヒンジ部18がダブルになっている。
【0022】
一方、下に位置するハンモック部材2aは、プラスチック段ボール製のフレーム8と、蓋付勢手段たる袋状にした弾性シート9と、プラスチック段ボール製の支枠10で構成される。支枠10は、フレーム板12と、そのフレーム板12の対向する2辺にハーフカットのヒンジ部19を介して連設した2枚の側枠11と、フレーム板12の開口13を開閉する形態にして観音ドア状に設けた2枚の補強用側枠11とからなる。従って下のハンモック部材2aは、図5(b)(※図5(b)は図6(b)を裏返した状態に描いてある。)のように補強用側枠11を開口13の中に収め、フレーム板12に側枠11を重ねて扁平に折り畳み得る。なお、前記側枠11にはハーフカットのヒンジ部20で折曲自在に連設した連結板21が設けられており、その連結板21の切込部22と前記補強用側枠11の切込部23が噛み合って側枠11と補強用側枠11が四角い枠状にロックされる。
【0023】
フレーム8と弾性シート9と支枠10の三部材は、上下のハンモック部材2a,2bとも次のようにして一体化されている。先ず弾性シート9の中にフレーム8を入れ込む。次に弾性シート9に包まれたフレーム8を支枠10のフレーム板12に重ね合わせ、フレーム8とフレーム板12の対向する2辺に断面コ字状のクランプバー24を嵌め、そのクランプバー24でフレーム8とフレーム板12及び弾性シート9を一体にクランプする。よってクランプバー24を着け外しするだけで支枠10に対するフレーム8の着脱が簡単に行えるため、図7のようにフレーム8を包む弾性シート9の交換が簡単に行える。また、フレーム8の2辺がクランプバー24(芯材)で補強されるため、使用時のフレーム8の変形が防止できる。
【0024】
実施例の運搬箱は以上のように構成されているため、図3のように箱1を扁平に折り畳み、その箱1の中に図5(a)のように扁平に折り畳んだ上のハンモック部材2bを入れ、さらにその上に図5(b)のように扁平に折り畳んだ下のハンモック部材2aを入れて蓋5を閉じることができる。
【0025】
この運搬箱で荷物Wを輸送する場合は、先ず下のハンモック部材2aを箱1から取り出し、図8のように側枠11と補強用側枠11を起立させ、側枠11の連結板21を補強用側枠11に差し込んで組み立てる。次に上のハンモック部材2bを取り出してから箱1を組み立てる。
【0026】
次に箱1の中に先に組み立てた下のハンモック部材2aを入れて弾性シート9の中央に荷物Wをセットする。次に上のハンモック部材2bを箱1の中にセットする。このときハンモック部材2bに荷物Wが当たるが、上下の弾性シート9,9が図4のように互いに変形して荷物Wを包み込む。この状態で上のハンモック部材2bには蓋付勢手段たる弾性シート9の変形に伴う反力で箱1から飛び出す向きの力が作用するが、側枠11の上縁が係合段部たるモール部材16b,16dの下縁に引っ掛かって突張り状態になるため、蓋5で押さえずとも上のハンモック部材2bがロックされる。
【0027】
次に箱1から荷物Wを取り出す場合は、蓋5を開けて上のハンモック部材2bを取り外す。それにはハンモック部材2bの側枠11を僅かに押し下げて側枠11とモール部材16b,16dの係合を解き、側枠11を内側に倒せば簡単に箱1から抜き出せる。
【0028】
以上本発明を実施の形態及び実施例について説明したが、もちろん本発明はそれらに限定されるものではない。例えば、ハンモック部材は必ずしも上下をペアにして使用する必要はなく、上又は下のどちらか一方にのみ弾性シートを設けるようにしてもよい。また、下のハンモック部材は、支枠に相当する部材を箱側に形成し、その部分に弾性シート付きのフレームを設置するようにしてもよい。また、実施例では上のハンモック部材をフレームと弾性シートと支枠の三部材で形成したが、例えば側枠をフレームと一体に、すなわちフレームの対向する2辺に屈曲自在に連設し、その側枠からベルト状の弾性シートを通してフレーム外周に巻き掛けるようにしてもよい。そうすれば、フレームと支枠を別体にする必要はない。
また、蓋付勢手段は、実施例以外にも、例えば、底板に荷物を直に又はクッション材を介して設置し、その荷物を落とし蓋で押し付けて落とし蓋側の弾性シートから反力を得るようにしたり、或いは落とし蓋のフレーム板を開口のない板(つまり弾性シートを設けない単なる板)で形成し、下のハンモック部材の弾性シートに荷物を沈ませてその反動で落とし蓋が押し上げられるようにしてもよい。
【0029】
【発明の効果】
本発明の運搬箱は、荷物を押さえた反動で落とし蓋が持ち上げられる力を利用し、落とし蓋の側枠上縁と係合段部を係合させて落とし蓋をロックするようにしたため、外に被せる蓋で落とし蓋の浮き上がりを押さえる従来構造に比べて荷物の設置が楽に行える。

BACKGROUND OF THE INVENTION
The present invention relates to a transport box in which a load is pressed and fixed with a drop lid.
[0002]
[Prior art]
Conventionally, as shown in FIG. 9, there is a transport box 100 in which a load is pressed by a hammock member 101 b that is a drop lid, and the lift of the drop lid is pressed by a lid 104 that covers the outside.
[0003]
[Problems to be solved by the invention]
The conventional transport box 100 has a problem in that workability is poor because it is necessary to cover the lid 104 while holding the dropping lid with one hand because the lid 104 covers the floating of the dropping lid.
[0004]
[Means for Solving the Problems]
A box that is surrounded by a side plate around the bottom plate, a drop lid that holds the load in the box from above, and a lid biasing means that applies an upward force to the drop lid by the reaction of holding the load with the drop lid The side plate of the box has a molding member attached to the upper edge of the box, and the lower edge of the portion covering the inner surface of the side plate of the molding member serves as an engaging step, while the drop lid is opposed to the frame plate. A side frame that can be bent is provided continuously on the two sides, and the upper edge of the side frame is hooked under the engaging step portion against the upward force of the lid biasing means to counteract in a tension state. In addition, the side frame is pushed down against the upward force by the lid urging means to disengage from the engagement step portion, and in that state, the side frame can be tilted inward to be extracted from the box. Provide a shipping box that is a thing .
[0005]
This transport box uses the force by which the drop lid is lifted by the reaction of holding the load, and the drop lid is locked by engaging the upper edge of the side frame of the drop lid and the engaging step. Luggage can be installed more easily than the conventional structure where the drop lid is held up by the cover.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the exploded perspective view of FIG. In FIG. 1, 1 is a box, 2a is a hammock member, 2b is a hammock member as a drop lid, and W is a load. In the box 1, a side plate 4 is raised around a square bottom plate 3, and a lid 5 is connected to the upper edge of one side plate 4. The material of the box 1 may be any material such as cardboard, corrugated paper, plastic corrugated cardboard, etc. However, if the baggage W is likely to be affected by static electricity, use conductive plastic corrugated cardboard. Is good.
[0007]
Since the two hammock members 2a and 2b are of the same structure and used in different directions, only the lower hammock member 2a will be described, and the upper hammock member 2b and the lower hammock member 2a will be described. The same reference numerals are given and description thereof is omitted.
[0008]
The hammock member 2a includes a square frame-shaped frame 8 having a window hole 7, an endless belt-like (sleeve shape) wound around the outer periphery of the frame 8, and an elastic sheet 9 serving as a lid urging means. 1 comprises three members of a support frame 10 that stops at an intermediate position inside.
[0009]
The frame 8 may be made of the same material as that of the box 1, but is preferably a plastic cardboard having excellent strength. The frame 8 is, for example, a quadrangle having a shape that substantially matches (or is slightly smaller) the inside of the box 1, and has a frame shape in which a large window hole 7 is punched. Of course, the shape of the frame 8 can be changed in accordance with the shape of the box 1, and the shape of the window hole 7 is not limited to a square.
[0010]
The elastic sheet 9 has an endless belt shape and is formed in a shape that fits the outer periphery of the frame 8. The elastic sheet 9 may be in the form of a bag in which one opening edge of the belt is closed in addition to the belt shape. Rather, it is easier to use the elastic sheet 9 in the form of a bag because the elastic sheet 9 is less likely to be displaced on the frame 8. The elastic sheet 9 may be made of any material that can be applied to the hammock packaging, such as polyurethane-based thermoplastic elastomer, polyamide, natural rubber, synthetic rubber, and polyethylene. In addition, a conductive material such as metal powder or carbon powder or an antistatic agent may be kneaded into the elastic sheet 9 so that the load W is not adversely affected by static electricity. Furthermore, the form of the elastic sheet 9 is not limited to a planar shape, and may be a cell-like structure or a bubble sheet structure in which a large number of closed cells sealed with gas are formed on a synthetic resin film.
[0011]
The support frame 10 includes a side frame 11 along the inner side of the side plate 4 of the box 1 and a frame plate 12 installed on the upper edge of the side frame 11. The shape of the frame plate 12 is substantially the same as that of the frame 8, and a large opening 13 corresponding to the window hole 7 of the frame 8 is provided. The height of the support frame 10, that is, the height of the side frame 11 is slightly less than ½ of the side plate 4 of the box 1, and the sum of the side frames 11 and 11 stacked vertically is slightly higher than the height of the side plate 4 of the box 1. It is set to be smaller.
[0012]
Although not shown, the side plate 4 of the box 1 is provided with a protruding engagement step portion that engages with the upper edges of the side frames 11 and 11 of the upper hammock member 2b and prevents the upper movement thereof. ing.
[0013]
Next, the usage method of the transport box of this invention is demonstrated. First, as shown by arrow B in FIG. 1, the frame 8 is inserted into the elastic sheet 9, and the elastic sheet 9 is wound around the outer periphery of the frame 8. Next, the support frame 10 of the hammock member 2a is set in the box 1, and the frame 8 with the elastic sheet 9 is placed thereon. Next, the load W is placed on the center of the elastic sheet 9 of the hammock member 2a, and the hammock member 2b, which is a drop lid composed of the frame 8 with the elastic sheet 9 and the support frame 10, is placed thereon, and the lid 5 is further placed thereon. Cover. If it does so, similarly to FIG.9 (b) of a prior art, the load W will be pinched | interposed between the elastic sheets 9 and 9 of both hammock members 2a and 2b, and it will hold | maintain so that it may not move.
[0014]
In addition, since the elastic sheet 9 is an endless belt shape or bag shape and is doubled at the window hole 7 portion of the frame 8, the strength of the elastic sheet 9 can be increased as compared with the conventional case. The tension of the elastic sheet 9 can be easily adjusted by changing the dimensions of the elastic sheet 9. That is, if the elastic sheet 9 is dimensioned to fit the frame 8, the tension becomes strong, and if the elastic sheet 9 is loose, the tension becomes loose. As a result, it is possible to prevent a trouble that the baggage W is excessively pressed, and conversely, a problem that the compression force is too weak and the fixing of the baggage W becomes unstable.
[0015]

On the other hand, the lower hammock member 2a includes a plastic cardboard frame 8, a bag-like elastic sheet 9 serving as a lid biasing means, and a plastic cardboard support frame 10. The support frame 10 is configured to open and close a frame plate 12, two side frames 11 connected to two opposite sides of the frame plate 12 via a half-cut hinge portion 19, and an opening 13 of the frame plate 12. And two reinforcing side frames 11 provided in the shape of a door. Therefore, the lower hammock member 2a has the reinforcing side frame 11 in the opening 13 as shown in FIG. 5 (b) (* FIG. 5 (b) is drawn upside down in FIG. 6 (b)). The side frame 11 can be overlapped on the frame plate 12 and folded flat. The side frame 11 is provided with a connecting plate 21 which is connected to be bent by a half-cut hinge portion 20, and the cut portion 22 of the connecting plate 21 and the reinforcing side frame 11 are cut. The side frames 11 and the reinforcing side frame 11 are locked in a square frame shape by engaging the portion 23.
[0023]
The three members of the frame 8, the elastic sheet 9, and the support frame 10 are integrated with the upper and lower hammock members 2a and 2b as follows. First, the frame 8 is inserted into the elastic sheet 9. Next, the frame 8 wrapped in the elastic sheet 9 is superposed on the frame plate 12 of the support frame 10, and a clamp bar 24 having a U-shaped cross section is fitted to two opposite sides of the frame 8 and the frame plate 12. Thus, the frame 8, the frame plate 12, and the elastic sheet 9 are clamped together. Therefore, since the frame 8 can be easily attached to and detached from the support frame 10 simply by attaching and detaching the clamp bar 24, the elastic sheet 9 enclosing the frame 8 can be easily replaced as shown in FIG. Further, since the two sides of the frame 8 are reinforced by the clamp bar 24 (core material), deformation of the frame 8 during use can be prevented.
[0024]
Since the transport box of the embodiment is configured as described above, the box 1 is folded flat as shown in FIG. 3, and the hammock member is folded flatly as shown in FIG. 2b can be put, and further, the lower hammock member 2a folded flatly as shown in FIG. 5B can be put thereon, and the lid 5 can be closed.
[0025]
When transporting the cargo W by this transport box, first, the lower hammock member 2a is taken out from the box 1, the side frame 11 and the reinforcing side frame 11 are erected as shown in FIG. It is inserted into the reinforcing side frame 11 and assembled. Next, the box 1 is assembled after the upper hammock member 2b is taken out.
[0026]
Next, the lower hammock member 2 a previously assembled is put into the box 1 and the luggage W is set in the center of the elastic sheet 9. Next, the upper hammock member 2 b is set in the box 1. At this time, the load W hits the hammock member 2b, but the upper and lower elastic sheets 9, 9 are deformed to wrap around the load W as shown in FIG. In this state, the upper hammock member 2b is subjected to a force in the direction of jumping out from the box 1 due to the reaction force accompanying the deformation of the elastic sheet 9 as the lid biasing means, but the upper edge of the side frame 11 is the molding that is the engaging step portion. The upper hammock member 2b is locked without being pressed by the lid 5 because it is hooked on the lower edges of the members 16b and 16d.
[0027]
Next, when taking out the load W from the box 1, the lid 5 is opened and the upper hammock member 2b is removed. For this purpose, the side frame 11 of the hammock member 2b is slightly pushed down to disengage the side frame 11 from the molding members 16b and 16d, and the side frame 11 can be easily pulled out from the box 1 by tilting it inward.
[0028]
Although the present invention has been described with reference to the embodiments and examples, the present invention is not limited to them. For example, the hammock members do not necessarily have to be used in pairs, and an elastic sheet may be provided only on either the upper or lower side. Further, the lower hammock member may be formed with a member corresponding to a support frame on the box side, and a frame with an elastic sheet may be installed in that portion. In the embodiment, the upper hammock member is formed by three members, that is, a frame, an elastic sheet, and a supporting frame. For example, the side frame is integrally provided with the frame, that is, continuously connected to two opposite sides of the frame so as to be freely bent. You may make it wind around a frame outer periphery from a side frame through a belt-shaped elastic sheet. Then, it is not necessary to make the frame and the support frame separate.
In addition to the embodiment, the lid urging means, for example, installs a load directly on the bottom plate or via a cushion material, and presses the load with a drop lid to obtain a reaction force from the elastic sheet on the drop lid side. Or the frame plate of the drop lid is formed of a plate without an opening (that is, a simple plate not provided with an elastic sheet), the luggage is sunk in the elastic sheet of the lower hammock member, and the drop lid is pushed up by the reaction. You may do it.
[0029]
【The invention's effect】
For tote boxes of the present invention, which utilizes the force closure dropped in reaction to holding the package is lifted, and so as to lock the lid down to engage the side frame on the edge and the engaging step portion of the drop lid, Luggage can be set up more easily than the conventional structure where the lid is placed on the outside to keep the drop lid from lifting.
