Description

物品包装構造Packaging structure
　本発明は物品包装構造に関する。 The present invention relates to an article packaging structure.
　薄型の物品、例えば液晶パネルのような物品は、包装トレイに入れられて搬送されることが多い。包装トレイを用いた物品包装構造の例を特許文献１、２に見ることができる。 Thin articles, such as liquid crystal panels, are often transported in a packaging tray. Examples of the article packaging structure using the packaging tray can be seen in Patent Documents 1 and 2.
　特許文献１には液晶表示装置を収納する収納部を備えた梱包トレイが記載されている。収納部の裏面には突起部が形成され、梱包トレイを複数段積層したとき、上段の梱包トレイの突起部が下段の梱包トレイに収納された液晶表示装置を押圧して液晶表示装置を固定する。 Patent Document 1 describes a packaging tray having a storage unit for storing a liquid crystal display device. A protrusion is formed on the back surface of the storage unit, and when a plurality of packing trays are stacked, the protrusion of the upper packing tray presses the liquid crystal display device stored in the lower packing tray to fix the liquid crystal display device. .
　特許文献２には表示素子収納凹部を備えた包装トレイが記載されている。この包装トレイには、複数の包装トレイを積み重ねた際に、上下の包装トレイのうちの少なくとも一方との重ね合わせ位置を規定する位置規定用凹部が設けられている。包装トレイは、熱可塑性プラスチックシートを加熱して軟化させ、軟らかい間に外力（真空、圧空等）を加えて成形し、その後シートを冷却、固化させたものである。 Patent Document 2 describes a packaging tray having a display element housing recess. The packaging tray is provided with a position-defining recess that defines an overlapping position with at least one of the upper and lower packaging trays when a plurality of packaging trays are stacked.

　物品がこれから組み立て工程に送られる部品である場合、包装トレイとしてはコストの安い合成樹脂成型品からなるトレイが用いられることが多い。すなわち特許文献２に記載された包装トレイと同種のものである。このような、熱可塑性プラスチックシートを真空成型あるいは圧空成型した包装トレイは、一般的に剛性が高いとは言えない。とりわけ、包装されるのが液晶パネルのような薄型の物品であると包装トレイも薄型形状となり、包装トレイの剛性はますます低下する。 When the article is a part to be sent to the assembly process from now on, a tray made of a synthetic resin molded product with low cost is often used as the packaging tray. That is, it is the same kind as the packaging tray described in Patent Document 2. Such a packaging tray in which a thermoplastic sheet is formed by vacuum molding or pressure forming cannot generally be said to have high rigidity. In particular, if a thin article such as a liquid crystal panel is packaged, the packaging tray also has a thin shape, and the rigidity of the packaging tray is further reduced.
　剛性不足の包装トレイは収納物の質量でたわみやすい。たわみは包装トレイ全体にわたって生じる場合もあるし、局部的に生じる場合もある。いずれにせよ、包装トレイがたわむと収納された物品に応力や圧力がかかり、物品が破損する危険性が増す。包装トレイを複数段積み重ねて持ち運ぶこととすれば、応力や圧力がさらに増し、物品が破損する危険性が一層増大する。物品が破損しないようにしようと思えば、包装トレイの厚みを厚くするか、包装トレイを極めて慎重に取り扱わざるを得ず、スピーディーに作業を進めることができない。このため、包装トレイのコストや作業コストが余計にかかっていた。 ¡Packaging trays with insufficient rigidity are easy to bend due to the mass of the stored items. Deflection can occur throughout the packaging tray or it can occur locally. In any case, when the packaging tray bends, stress or pressure is applied to the stored article, increasing the risk of damage to the article. If the packaging trays are stacked and carried, the stress and pressure are further increased, and the risk of damaging the article is further increased. In order to prevent the article from being damaged, the thickness of the packaging tray must be increased or the packaging tray must be handled very carefully, and the work cannot be carried out speedily. For this reason, the cost of the packaging tray and the work cost are excessive.
　本発明は上記の点に鑑みなされたものであり、合成樹脂シートの成型品からなる包装トレイを用いて物品を包装するに際し、物品包装構造の剛性を高め、物品破損の危険性を低減させることができる物品包装構造を提供することを目的とする。 The present invention has been made in view of the above points, and when packaging an article using a packaging tray made of a molded product of a synthetic resin sheet, the rigidity of the article packaging structure is increased and the risk of damage to the article is reduced. An object of the present invention is to provide an article packaging structure that can be used.
　本発明に係る物品包装構造は、合成樹脂シートの成型品からなる包装トレイを備え、前記包装トレイに形成された物品収納凹部に物品が収納され、前記物品を収納した前記包装トレイは複数段積層されるものであって、複数段積層された前記包装トレイのうち、最下段の包装トレイの下面に補強シートが添えられる。 An article packaging structure according to the present invention includes a packaging tray made of a molded product of a synthetic resin sheet, the article is stored in an article storage recess formed in the packaging tray, and the packaging tray storing the article is stacked in multiple layers. A reinforcing sheet is attached to the lower surface of the lowermost packaging tray among the packaging trays stacked in a plurality of stages.
　上記構成の物品包装構造において、前記補強シートは両面接着テープで前記最下段の包装トレイに貼り付けられることが好ましい。 In the article packaging structure having the above configuration, the reinforcing sheet is preferably attached to the lowermost packaging tray with a double-sided adhesive tape.
　上記構成の物品包装構造において、前記補強シートは接着剤で前記最下段の包装トレイに固定されることが好ましい。 In the article packaging structure having the above-described configuration, the reinforcing sheet is preferably fixed to the lowermost packaging tray with an adhesive.
　上記構成の物品包装構造において、前記補強シートは前記最下段の包装トレイの下面に形成された凹部にはめ込まれることが好ましい。 In the article packaging structure configured as described above, it is preferable that the reinforcing sheet is fitted in a recess formed on the lower surface of the lowermost packaging tray.
　上記構成の物品包装構造において、前記補強シートは複数段積層された前記包装トレイの全てに添えられることが好ましい。 In the article packaging structure having the above configuration, it is preferable that the reinforcing sheet is attached to all of the packaging trays laminated in a plurality of stages.
　上記構成の物品包装構造において、複数段積層された前記包装トレイに対し、保護袋と箱の少なくとも一方が包装用資材として用いられることが好ましい。 In the article packaging structure having the above configuration, it is preferable that at least one of a protective bag and a box is used as a packaging material for the packaging trays stacked in a plurality of stages.
　上記構成の物品包装構造において、前記部品収納凹部の外側に隣接して支持脚部が形成され、前記支持脚部が前記補強シートの上面に密着することが好ましい。 In the article packaging structure having the above configuration, it is preferable that a support leg is formed adjacent to the outside of the component housing recess, and the support leg is in close contact with the upper surface of the reinforcing sheet.
　上記構成の物品包装構造において、前記部品収納凹部は前記包装トレイに複数ずつ形成されていることが好ましい。 In the article packaging structure configured as described above, it is preferable that a plurality of the component storage recesses are formed in the packaging tray.
　上記構成の物品包装構造において、前記物品はＬＣＤモジュールであることが好ましい。 In the article packaging structure having the above configuration, the article is preferably an LCD module.
　本発明によると、物品を収納した包装トレイを複数段積層した状態で箱に収納するに際し、複数段積層された包装トレイのうち最下段の包装トレイの下面に補強シートが添えられることとしたことにより、最下段の包装トレイのたわみが防止されるとともに、その上に積層された包装トレイのたわみも防止され、物品破損の危険性が大幅に減少する。 According to the present invention, when a plurality of packaging trays containing articles are stacked in a box, the reinforcing sheet is attached to the lower surface of the lowermost packaging tray among the packaging trays stacked in multiple stages. As a result, the lowermost packaging tray is prevented from being bent, and the packaging tray laminated thereon is also prevented from being bent, thereby greatly reducing the risk of damaging the article.

That is, a thermoplastic synthetic resin sheet is heated and softened, and pressure (vacuum pressure or air pressure) is applied between the soft sheets to suck or press the mold surface to obtain the same tray shape as the mold surface. is there. As the synthetic resin sheet, a foamed sheet or a non-foamed sheet such as polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), and polyethylene (PE) can be used. A synthetic resin sheet having a thickness corresponding to the mass of the article is selected from synthetic resin sheets having a thickness of 0.5 mm to 2.0 mm.
　包装トレイ１の平面形状は矩形であり、上面には矩形の物品収納凹部２が２列４行にわたり計８個形成されている。物品収納凹部２に収納される物品１０は液晶パネル及びその付属部品により構成されるＬＣＤモジュールであって、モバイル電子機器用の小型のものである。 The planar shape of the packaging tray 1 is rectangular, and a total of eight rectangular article storage recesses 2 are formed in two rows and four rows on the upper surface. An article 10 stored in the article storage recess 2 is an LCD module constituted by a liquid crystal panel and its accessory parts, and is a small-sized one for mobile electronic devices.
　図５に示す通り、包装トレイ１は四周を囲む周壁部３を備えている。周壁部３の下端が接地箇所となる。また物品収納凹部２の外側に隣接して支持脚部４が形成されており、支持脚部４の下端も接地箇所となる。 As shown in FIG. 5, the packaging tray 1 includes a peripheral wall portion 3 that surrounds four sides. The lower end of the peripheral wall part 3 becomes a grounding location. A support leg 4 is formed adjacent to the outside of the article storage recess 2, and the lower end of the support leg 4 also serves as a grounding location.
　物品収納凹部２の外側に隣接して支持脚部４が形成されていることにより、物品収納凹部２の荷重負担力が増す。すなわち、包装トレイ１の材料である熱可塑性合成樹脂シートとして肉厚の薄いものを選択することが可能になる。 The load bearing force of the article storing recess 2 is increased by forming the support leg 4 adjacent to the outside of the article storing recess 2. That is, it is possible to select a thin thermoplastic synthetic resin sheet as a material for the packaging tray 1.
　支持脚部４が下に突き出すことにより包装トレイ１の上面に凹部が形成されるが、この凹部は、図５に示す通り一方の側壁が内側にせり出し、オーバーハング部となっている。このオーバーハング部の上部は他の包装トレイ１の支持脚部４を受ける支持脚受部４ａとなる。 When the support leg 4 protrudes downward, a concave portion is formed on the upper surface of the packaging tray 1. As shown in FIG. 5, one side wall of the concave portion protrudes inward to form an overhang portion. The upper part of this overhang part becomes the support leg receiving part 4a which receives the support leg part 4 of the other packaging tray 1. FIG.
　周壁部３は下向きに広がったテーパ形状を有しており、包装トレイ１の上に別の包装トレイ１を重ねると下段の包装トレイ１の周壁部３の外側に上段の包装トレイ１の周壁部３が被さる。すなわち包装トレイ１は積み上げること（スタッキング）が可能である。 The peripheral wall portion 3 has a taper shape spreading downward, and when another packaging tray 1 is stacked on the packaging tray 1, the peripheral wall portion of the upper packaging tray 1 is placed outside the circumferential wall portion 3 of the lower packaging tray 1. 3 is covered. That is, the packaging tray 1 can be stacked (stacked).
　上段の包装トレイ１の支持脚部４が下段の包装トレイ１の支持脚受部４ａに接地することにより、上下の包装トレイ１のレベル差は一定に維持される。これにより物品収納凹部２の上方に空間が確保され、物品１０は上方の包装トレイ１により圧迫されなくて済むことになる。 When the support leg 4 of the upper packaging tray 1 contacts the support leg receiving portion 4a of the lower packaging tray 1, the level difference between the upper and lower packaging trays 1 is maintained constant. As a result, a space is secured above the article storage recess 2, and the article 10 does not have to be pressed by the upper packaging tray 1.
　物品収納凹部２に物品１０を収納した包装トレイ１を図２に示す通り複数段積層する。複数段積層した包装トレイ１を図３に示す通り保護袋５に入れる。保護袋５はポリエチレン等からなる。包装トレイ１が入れられた後、保護袋５の口が閉じられ、粘着テープ６で封口される。これにより、包装トレイ１は保護袋５で包装されたことになる。 The packaging tray 1 storing the articles 10 in the article storing recess 2 is stacked in a plurality of stages as shown in FIG. A plurality of stacked packaging trays 1 are placed in a protective bag 5 as shown in FIG. The protective bag 5 is made of polyethylene or the like. After the packaging tray 1 is placed, the mouth of the protective bag 5 is closed and sealed with the adhesive tape 6. As a result, the packaging tray 1 is packaged with the protective bag 5.
　保護袋５で包装された包装トレイ１を、図４に示すように内スリーブ７で包む。この内スリーブ７を２個１組にして外スリーブ８に入れる。内スリーブ７と外スリーブ８は段ボール製である。段ボールは紙素材でもプラスチック素材でもどちらでもよい。 The packaging tray 1 wrapped with the protective bag 5 is wrapped with the inner sleeve 7 as shown in FIG. Two sets of the inner sleeves 7 are put into the outer sleeve 8. The inner sleeve 7 and the outer sleeve 8 are made of cardboard. The cardboard can be either paper or plastic.
　箱９の中に外スリーブ８を複数段入れる。箱９はカートンボックスである。カートンボックスの天面フラップを閉じ、粘着テープで封緘すれば、物品１０の梱包は完成する。 複数 Put a plurality of outer sleeves 8 in the box 9. Box 9 is a carton box. If the top flap of the carton box is closed and sealed with an adhesive tape, the packaging of the article 10 is completed.
　包装トレイ１を複数段積層した状態で収納する箱９として、ここでは段ボール製のカートンボックスを用いたが、合成樹脂製の通い箱のようなものを用いることとしても構わない。 As the box 9 for storing the packaging trays 1 in a state of being stacked in a plurality of layers, a carton box made of corrugated cardboard is used here, but it is also possible to use something like a plastic resin return box.
　上記包装用資材、すなわち保護袋５、内スリーブ７、外スリーブ８、及び箱９は、１つでも欠けることなく揃っていなければならない訳ではない。それらのうちいくつかを省いた包装も可能である。しかしながら、複数段積層した包装トレイ１を崩れないように保持するという観点からは、保護袋５と箱９の少なくとも一方を包装用資材として用いることが好ましい。 The above-mentioned packaging materials, that is, the protective bag 5, the inner sleeve 7, the outer sleeve 8, and the box 9 do not necessarily have to be aligned without being missing. Packaging without some of them is also possible. However, it is preferable to use at least one of the protective bag 5 and the box 9 as a packaging material from the viewpoint of holding the packaging trays 1 stacked in a plurality of stages so as not to collapse.
　本発明は、複数段積層された包装トレイ１のうち、最下段の包装トレイ１の下面に補強シート２０が添えられることを特徴としている。以下、補強シート２０の添え方の実施形態を図５から図１０までの図に基づき説明する。 The present invention is characterized in that a reinforcing sheet 20 is attached to the lower surface of the lowermost packaging tray 1 among the packaging trays 1 laminated in a plurality of stages. Hereinafter, an embodiment of how to attach the reinforcing sheet 20 will be described with reference to FIGS.
　図５と図６に示す第１実施形態では、複数段積層される包装トレイ１のうち、最下段のもののみに補強シート２０が添えられる。補強シート２０の平面投影形状は包装トレイ１の平面投影形状と同じである。図に示す通り、包装トレイ１は接地箇所である周壁部３の下端と支持脚部４の下端を補強シート２０の上面に密着させる形で補強シート２０に載置される。 In the first embodiment shown in FIG. 5 and FIG. 6, the reinforcing sheet 20 is attached only to the lowest tray among the packaging trays 1 stacked in a plurality of stages. The planar projection shape of the reinforcing sheet 20 is the same as the planar projection shape of the packaging tray 1. As shown in the figure, the packaging tray 1 is placed on the reinforcing sheet 20 in such a manner that the lower end of the peripheral wall portion 3 and the lower end of the support leg portion 4 that are the ground contact points are in close contact with the upper surface of the reinforcing sheet 20.
　補強シート２０は剛性の他にある程度の緩衝性を備えたものであることが望ましく、例えばプラスチック段ボール（ＰＰ、ＰＳ、ＰＥなどを材料とするもの）の厚み４～５ｍｍのものを用いることができる。あるいは、包装トレイ１と同じ材料（ＰＰ、ＰＳ、ＰＥＴ、ＰＥなど）の厚み０．５～２．０ｍｍのものを用いることができる。言うまでもないがここに掲げた材料は単なる例示であり、発明を限定するものではない。 The reinforcing sheet 20 is desirably provided with a certain degree of cushioning in addition to rigidity. For example, a plastic corrugated cardboard (made of PP, PS, PE, etc.) having a thickness of 4 to 5 mm can be used. . Alternatively, the same material (PP, PS, PET, PE, etc.) as the packaging tray 1 having a thickness of 0.5 to 2.0 mm can be used. Needless to say, the materials listed here are merely examples and do not limit the invention.
　複数段積層された包装トレイ１の中で最下段の包装トレイ１の下面に補強シート２０を添えた状態のものを保護袋５で包装することにより、最下段の包装トレイ１の剛性不足が補われ、その包装トレイ１のたわみが防止される。最下段の包装トレイ１がたわまなければ、その上に積層された包装トレイ１もたわまない。これにより、物品１０の破損の危険性が大幅に減少する。 By packaging a plurality of stacked packaging trays 1 with the reinforcing sheet 20 attached to the lower surface of the lowermost packaging tray 1 with the protective bag 5, the lack of rigidity of the lowermost packaging tray 1 is compensated. And the deflection of the packaging tray 1 is prevented. If the lowermost packaging tray 1 does not bend, the packaging tray 1 laminated thereon does not bend. This greatly reduces the risk of damage to the article 10.
　補強シート２０を最下段の包装トレイ１の下面に単に添えるだけで本発明の目的は達成される。しかしながら、単に添えただけでは保護袋５に入れるときに補強シート２０が水平方向にずれる可能性がある。補強シート２０がずれる度にそれを直していたのでは作業が停滞する。これを防ぐため、補強シート２０を両面接着テープ（図示せず）で包装トレイ１に貼り付けることとしてもよい。あるいは、補強シート２０を接着剤（図示せず）で包装トレイ１に固定することとしてもよい。このように包装トレイ１と補強シート２０を固定すれば、包装トレイ１の変形やたわみをさらに少なくすることができる。 The object of the present invention can be achieved by simply attaching the reinforcing sheet 20 to the lower surface of the lowermost packaging tray 1. However, the reinforcing sheet 20 may be shifted in the horizontal direction when the protective bag 5 is simply attached. If the reinforcing sheet 20 is corrected each time it deviates, the work is stagnant. In order to prevent this, the reinforcing sheet 20 may be attached to the packaging tray 1 with a double-sided adhesive tape (not shown). Alternatively, the reinforcing sheet 20 may be fixed to the packaging tray 1 with an adhesive (not shown). If the packaging tray 1 and the reinforcing sheet 20 are fixed in this way, the deformation and deflection of the packaging tray 1 can be further reduced.
　補強シート２０の添え方の第２実施形態を図７と図８に示す。第２実施形態でも、複数段積層される包装トレイ１のうち、最下段のもののみに補強シート２０が添えられる。第２実施形態の補強シート２０は第１実施形態の補強シート２０より一回り小さく、包装トレイ１の下面に形成された凹部１ａにすっぽりとはまり込む大きさになっている。凹部１ａにはめ込まれた状態の補強シート２０の下面と、包装トレイ１の周壁部３の下端とがほぼ面一になるよう、支持脚部４の下端は補強シート２０の厚み分だけ周壁部３の下端より高くされている。 7 and 8 show a second embodiment of how to attach the reinforcing sheet 20. Also in the second embodiment, the reinforcing sheet 20 is attached to only the lowest tray among the packaging trays 1 stacked in a plurality of stages. The reinforcing sheet 20 of the second embodiment is slightly smaller than the reinforcing sheet 20 of the first embodiment, and has a size that fits perfectly into the recess 1 a formed on the lower surface of the packaging tray 1. The lower end of the support leg 4 is the same as the thickness of the reinforcing sheet 20 so that the lower surface of the reinforcing sheet 20 fitted in the recess 1a and the lower end of the peripheral wall 3 of the packaging tray 1 are substantially flush with each other. It is higher than the lower end.
　複数段積層された包装トレイ１の中で最下段の包装トレイ１の下面に形成された凹部１ａに補強シート２０をはめ込んだ状態のものを保護袋５で包装することにより、最下段の包装トレイ１の剛性不足が補われ、その包装トレイ１のたわみが防止される。最下段の包装トレイ１がたわまなければ、その上に積層された包装トレイ１もたわまない。これにより、物品１０の破損の危険性が大幅に減少する。 The lowermost packaging tray 1 is packaged with the protective bag 5 in a state where the reinforcing sheet 20 is fitted in the recess 1a formed on the lower surface of the lowermost packaging tray 1 among the packaging trays 1 stacked in a plurality of stages. The lack of rigidity of 1 is compensated, and the deflection of the packaging tray 1 is prevented. If the lowermost packaging tray 1 does not bend, the packaging tray 1 laminated thereon does not bend. This greatly reduces the risk of damage to the article 10.
　第２実施形態の補強シート２０は包装トレイ１の下面の凹部１ａにはめ込まれているので、第１実施形態の補強シート２０のように水平方向にずれる心配はない。しかしながら凹部１ａから脱落する可能性はあるので、補強シート２０を両面接着テープで包装トレイ１に貼り付けて脱落を防ぐこととしてもよい。あるいは、補強シート２０を接着剤で包装トレイ１に固定することとしてもよい。このように包装トレイ１と補強シート２０を固定すれば、包装トレイ１の変形やたわみをさらに少なくすることができる。 Since the reinforcing sheet 20 of the second embodiment is fitted in the recess 1a on the lower surface of the packaging tray 1, there is no fear of shifting in the horizontal direction unlike the reinforcing sheet 20 of the first embodiment. However, since there is a possibility of dropping from the recess 1a, the reinforcing sheet 20 may be stuck to the packaging tray 1 with a double-sided adhesive tape to prevent the dropping. Alternatively, the reinforcing sheet 20 may be fixed to the packaging tray 1 with an adhesive. If the packaging tray 1 and the reinforcing sheet 20 are fixed in this way, the deformation and deflection of the packaging tray 1 can be further reduced.
　第１実施形態と第２実施形態によれば、複数段積層される包装トレイ１のうち、最下段の包装トレイ１に対してのみ下面に補強シート２０を添えることにより、複数段積層された包装トレイ１全体の変形やたわみを抑え、物品１０にかかる応力や圧力を緩和できる。その結果、物品１０の破損の危険が少ない物品包装構造とすることができる。物品１０がＬＣＤモジュールのような繊細な部品である場合、本発明のメリットは特に大きい。また補強シート２０が添えられるのは最下段の包装トレイ１だけであるから、低コストで効果的に補強することができる。 According to the first embodiment and the second embodiment, among the packaging trays 1 that are laminated in a plurality of stages, only the lowermost packaging tray 1 is attached with the reinforcing sheet 20 on the lower surface, thereby packaging in a plurality of stages. The deformation and deflection of the entire tray 1 can be suppressed, and the stress and pressure applied to the article 10 can be relaxed. As a result, it is possible to provide an article packaging structure with less risk of damage to the article 10. When the article 10 is a delicate part such as an LCD module, the merit of the present invention is particularly great. Further, since the reinforcing sheet 20 is attached only to the lowermost packaging tray 1, it can be effectively reinforced at low cost.
　複数段積層された包装トレイ１を保護袋５に入れるとき、一方の手で保護袋５の口を広げておき、他方の手で包装トレイ１の積層体を持って保護袋５に入れるので、包装トレイ１の積層体の支持はどうしても片持ち梁（カンチレバー）の形になり、包装トレイ１の局部に曲げ応力が集中していた。最下段の包装トレイ１の下面に補強シート２０を添えたことによりそのような応力は緩和されるから、包装作業時に物品１０が破損する危険性が軽減され、作業者は安心して作業を行うことができる。 When putting the multi-layer stacked packaging tray 1 into the protective bag 5, the mouth of the protective bag 5 is widened with one hand, and the laminated body of the packaging tray 1 is put into the protective bag 5 with the other hand. The support of the laminated body of the packaging tray 1 was in the form of a cantilever, and bending stress was concentrated on the local part of the packaging tray 1. Since the stress is relieved by attaching the reinforcing sheet 20 to the lower surface of the lowermost packaging tray 1, the risk of damaging the article 10 during the packaging operation is reduced, and the operator can work with peace of mind. Can do.
　補強シート２０が緩衝性を有するものであれば、保護袋５で包装されたもの全体、あるいは箱９で梱包されたもの全体の緩衝性を向上させることができる。これにより、運搬時の振動や落下の衝撃に対する耐性が増し、物品１０に外観不良が生じる危険を低減することができる。 If the reinforcing sheet 20 has a buffering property, the buffering property of the whole packaged by the protective bag 5 or the packaged by the box 9 can be improved. Thereby, the tolerance with respect to the vibration at the time of conveyance and the impact of a fall increases, and the danger that the external appearance defect may arise in the articles | goods 10 can be reduced.
　補強シート２０の添え方の第３実施形態を図９に示す。第３実施形態は、第１実施形態において最下段の包装トレイ１の下面にのみ添えられていた補強シート２０を、複数段積層された包装トレイ１の全ての下面に添えることとしたものである。 FIG. 9 shows a third embodiment of how to attach the reinforcing sheet 20. In the third embodiment, the reinforcing sheet 20 attached only to the lower surface of the lowermost packaging tray 1 in the first embodiment is attached to all the lower surfaces of the packaging trays 1 stacked in a plurality of stages. .
　全ての包装トレイ１に補強シート２０を添えることにより、包装トレイ１の変形やたわみをさらに少なくすることができる。物品１０が大型で包装トレイ１も大型である場合など、この構成は特に効果を発揮する。 By attaching the reinforcing sheet 20 to all the packaging trays 1, the deformation and the deflection of the packaging tray 1 can be further reduced. This configuration is particularly effective when the article 10 is large and the packaging tray 1 is also large.
　補強シート２０は、単に包装トレイ１の下面に添えるだけでなく、両面接着テープで包装トレイ１に貼り付けたり、接着剤で包装トレイ１に固定したりすることができる。第３実施形態では補強シート２０と包装トレイ１が交互に積み重なるので、個々の補強シート２０をそれに対応する包装トレイ１に固定しておくことは、積層を崩さない上で大きな意味を持つ。 The reinforcing sheet 20 can be attached not only to the lower surface of the packaging tray 1 but also attached to the packaging tray 1 with a double-sided adhesive tape, or fixed to the packaging tray 1 with an adhesive. In the third embodiment, the reinforcing sheets 20 and the packaging trays 1 are alternately stacked. Therefore, fixing the individual reinforcing sheets 20 to the corresponding packaging trays 1 has a great meaning in keeping the stacking.
　補強シート２０の添え方の第４実施形態を図１０に示す。第４実施形態は、第２実施形態で最下段の包装トレイ１について行われた、包装トレイ１の下面の凹部１ａに補強トレイ２０をはめ込むというやり方を、複数段積層された包装トレイ１の全てに適用したものである。 FIG. 10 shows a fourth embodiment of how to attach the reinforcing sheet 20. In the fourth embodiment, all the packaging trays 1 that are stacked in a plurality of stages are arranged in the same manner as in the second embodiment, in which the reinforcing tray 20 is fitted in the recess 1a on the lower surface of the packaging tray 1. Is applied.
　全ての包装トレイ１に補強シート２０をはめ込むことにより、包装トレイ１の変形やたわみをさらに少なくすることができる。物品１０が大型で包装トレイ１も大型である場合など、この構成は特に効果を発揮する。 By fitting the reinforcing sheet 20 into all the packaging trays 1, the deformation and deflection of the packaging tray 1 can be further reduced. This configuration is particularly effective when the article 10 is large and the packaging tray 1 is also large.
　補強シート２０は、単に包装トレイ１の下面の凹部１ａにはめ込むだけでなく、両面接着テープで包装トレイ１に貼り付けたり、接着剤で包装トレイ１に固定したりすることができる。このようにすれば、積層された包装トレイ１を上段側から取り外して行くとき、はめ込まれていた補強シート２０が脱落して下段の包装トレイ１にかぶさり、物品１０の取り出しを阻害するという事態を招かなくて済む。 The reinforcing sheet 20 can be attached not only to the recess 1a on the lower surface of the packaging tray 1 but also attached to the packaging tray 1 with a double-sided adhesive tape, or fixed to the packaging tray 1 with an adhesive. In this way, when the stacked packaging tray 1 is removed from the upper side, the inserted reinforcing sheet 20 falls off and covers the lower packaging tray 1, thereby obstructing removal of the article 10. You don't have to invite me.
　以上、本発明の実施形態につき説明したが、本発明の範囲はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で種々の変更を加えて実施することができる。 The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.
　本発明は本発明は物品包装構造に広く適用可能であり、特に物品がＬＣＤモジュールのような繊細な部品である場合に適用の価値が高い。 The present invention can be widely applied to an article packaging structure, and is particularly valuable when the article is a delicate part such as an LCD module.
