図４は、実施の形態１のトレイ１を組み立てる途中の状態を示す斜視図である。トレイ１を組み立てるには、以下のようにする。まず、外側シート２の底壁４の上に、少なくとも１枚の中間シート３を載置する。次に、第一側壁５及び第二側壁６を第一折り曲げ線９及び第二折り曲げ線１０に沿ってそれぞれ内側に折り曲げる。次に、第一上壁７及び第二上壁８を第三折り曲げ線１１及び第四折り曲げ線１２に沿ってそれぞれ内側に折り曲げる。次に、第一固定タブ１５及び第二固定タブ１６を第五折り曲げ線１７及び第六折り曲げ線１８に沿ってそれぞれ内側に折り曲げる。次に、第一固定タブ１５及び第二固定タブ１６を、中間シート３の孔２３及び底壁４の孔１９に差し込む。これにより、トレイ１の組み立てが完了する。  FIG. 4 is a perspective view showing a state in the middle of assembling the tray 1 of the first embodiment. To assemble the tray 1, the following is performed. First, at least one intermediate sheet 3 is placed on the bottom wall 4 of the outer sheet 2. Next, the first side wall 5 and the second side wall 6 are bent inward along the first fold line 9 and the second fold line 10, respectively. Next, the first upper wall 7 and the second upper wall 8 are bent inward along the third fold line 11 and the fourth fold line 12, respectively. Next, the first fixing tab 15 and the second fixing tab 16 are bent inward along the fifth fold line 17 and the sixth fold line 18, respectively. Next, the first fixing tab 15 and the second fixing tab 16 are inserted into the hole 23 of the intermediate sheet 3 and the hole 19 of the bottom wall 4. Thereby, the assembly of the tray 1 is completed.

トレイ１を組み立てた状態では、以下のようになる。第一側壁５及び第二側壁６は、底壁４に対して垂直になる。第一上壁７及び第二上壁８は、底壁４に対して平行になる。第一固定タブ１５及び第二固定タブ１６の外周と、孔２３及び孔１９の内周との間の摩擦力により、第一固定タブ１５及び第二固定タブ１６が孔２３及び孔１９から抜けることが防止される。第一固定タブ１５及び第二固定タブ１６は、互いに接触する。  When the tray 1 is assembled, it is as follows. The first side wall 5 and the second side wall 6 are perpendicular to the bottom wall 4. The first upper wall 7 and the second upper wall 8 are parallel to the bottom wall 4. The first fixing tab 15 and the second fixing tab 16 come out of the hole 23 and the hole 19 due to the frictional force between the outer periphery of the first fixing tab 15 and the second fixing tab 16 and the inner periphery of the hole 23 and the hole 19. It is prevented. The first fixing tab 15 and the second fixing tab 16 are in contact with each other.

本実施の形態であれば、物流輸送時あるいは荷扱い時に、以下の効果が得られる。中間シート３が外側シート２により包まれていることで、中間シート３の位置が第一側壁５及び第二側壁６により規制される。このため、中間シート３の位置ずれが生じることを確実に防止できる。それゆえ、トレイ１の変形を確実に抑制できる。よって、被梱包物すなわち製品が、互いに接触したりして傷つくことを確実に抑制できる。  According to the present embodiment, the following effects can be obtained at the time of logistics transportation or cargo handling. Since the intermediate sheet 3 is wrapped by the outer sheet 2, the position of the intermediate sheet 3 is regulated by the first side wall 5 and the second side wall 6. For this reason, it can prevent reliably that the position shift of the intermediate sheet 3 arises. Therefore, the deformation of the tray 1 can be reliably suppressed. Therefore, it can suppress reliably that a to-be-packaged object, ie, a product, mutually contacts and is damaged.

第一固定タブ１５、第二固定タブ１６、孔１９及び孔２３は、第一上壁７及び第二上壁８を固定する固定手段の例である。本実施の形態であれば、簡単な構成で、第一上壁７及び第二上壁８を確実に固定できる。本実施の形態であれば、第一固定タブ１５及び第二固定タブ１６が中間シート３の孔２３に嵌合した状態になることで、中間シート３の位置を固定することもできる。本実施の形態であれば、第一固定タブ１５及び第二固定タブ１６が、中間シート３の孔２３だけでなく、底壁４の孔１９にも嵌合することで、第一上壁７及び第二上壁８をより確実に固定できる。このような構成に代えて、底壁４が孔１９を備えなくてもよい。すなわち、第一固定タブ１５及び第二固定タブ１６が中間シート３の孔２３だけに嵌合してもよい。また、すべての中間シート３が孔２３を備える構成に代えて、上層側の一部の中間シート３のみが孔２３を備えてもよい。  The first fixing tab 15, the second fixing tab 16, the hole 19, and the hole 23 are examples of fixing means for fixing the first upper wall 7 and the second upper wall 8. In the present embodiment, the first upper wall 7 and the second upper wall 8 can be reliably fixed with a simple configuration. If it is this Embodiment, the position of the intermediate sheet 3 can also be fixed because the 1st fixing tab 15 and the 2nd fixing tab 16 will be in the state fitted to the hole 23 of the intermediate sheet 3. FIG. In the present embodiment, the first fixing tab 15 and the second fixing tab 16 are fitted not only into the hole 23 of the intermediate sheet 3 but also into the hole 19 of the bottom wall 4, so that the first upper wall 7 And the 2nd upper wall 8 can be fixed more reliably. Instead of such a configuration, the bottom wall 4 may not have the holes 19. That is, the first fixing tab 15 and the second fixing tab 16 may be fitted only in the hole 23 of the intermediate sheet 3. Further, instead of the configuration in which all the intermediate sheets 3 are provided with the holes 23, only some of the intermediate sheets 3 on the upper layer side may be provided with the holes 23.

本実施の形態では、第一固定タブ１５及び第二固定タブ１６が一緒になって孔１９及び孔２３に嵌合している。このような構成に代えて、第一固定タブ１５及び第二固定タブ１６が別々の孔に嵌合してもよい。  In the present embodiment, the first fixing tab 15 and the second fixing tab 16 are fitted together in the hole 19 and the hole 23. Instead of such a configuration, the first fixing tab 15 and the second fixing tab 16 may be fitted in separate holes.

本発明における固定手段は、上記の構成に限定されない。例えば、以下のような固定手段でもよい。第一上壁７及び第二上壁８の下面を最上層の中間シート３の上面に接着剤または両面粘着テープにより接着してもよい。鉤部を有する第一固定タブ及び第二固定タブを第一上壁７及び第二上壁８にそれぞれ接続し、当該第一固定タブ及び第二固定タブの鉤部を底壁４の下面に係合させてもよい。その逆に、鉤部を有する第一固定タブ及び第二固定タブを底壁４に接続し、当該第一固定タブ及び第二固定タブの鉤部を第一上壁７及び第二上壁８の上面にそれぞれ係合させてもよい。  The fixing means in the present invention is not limited to the above configuration. For example, the following fixing means may be used. The lower surfaces of the first upper wall 7 and the second upper wall 8 may be bonded to the upper surface of the uppermost intermediate sheet 3 with an adhesive or a double-sided adhesive tape. The first fixing tab and the second fixing tab each having a flange portion are connected to the first upper wall 7 and the second upper wall 8, respectively, and the flange portions of the first fixing tab and the second fixing tab are connected to the lower surface of the bottom wall 4. It may be engaged. On the contrary, the first fixing tab and the second fixing tab having the flange portion are connected to the bottom wall 4, and the flange portions of the first fixing tab and the second fixing tab are connected to the first upper wall 7 and the second upper wall 8. You may engage with the upper surface of each.

FIG. 6 is a cross-sectional side view showing a state in which the product 90 is fitted in the recess 13 of the tray 1 of the first embodiment. As shown in these drawings, a product 90 that is an object to be packed can be fitted into each of the recesses 13 of the tray 1. The product 90 passes through the opening 20 of the intermediate sheet 3 and contacts the bottom wall 4.

図７は、実施の形態１のトレイ１を備える梱包装置３０の分解斜視図である。図８は、図７に示す梱包装置３０を組み立てた状態の斜視図である。図７に示すように、梱包装置３０は、複数のトレイ１と、パレット３１と、底トレイ３２と、側面シート３３と、天キャップ３４とを備える。パレット３１は、木製またはプラスチック製でもよい。底トレイ３２、側面シート３３、及び天キャップ３４は、段ボールシート製でもよい。  FIG. 7 is an exploded perspective view of the packaging device 30 including the tray 1 according to the first embodiment. FIG. 8 is a perspective view of the state in which the packaging device 30 shown in FIG. 7 is assembled. As shown in FIG. 7, the packing device 30 includes a plurality of trays 1, a pallet 31, a bottom tray 32, a side sheet 33, and a top cap 34. The pallet 31 may be made of wood or plastic. The bottom tray 32, the side sheet 33, and the top cap 34 may be made of cardboard sheets.

梱包装置３０は、以下のようにして組み立てられる。パレット３１の上に、底トレイ３２を置く。底トレイ３２の上にトレイ１を載せる。本実施の形態では、底トレイ３２の上に複数（６個）のトレイ１を並べることができる。底トレイ３２の上面にトレイ１の底壁４が接触する。製品９０が凹部１３に嵌め込まれたトレイ１を、複数段、積み重ねる。このとき、トレイ１の上の製品９０の位置と、当該トレイ１の下の製品９０の位置とが、前後及び左右の水平方向で一致するようにする。次に、積み重ねられたトレイ１の周囲を覆うように、側面シート３３を配置する。次に、積み重ねられたトレイ１の上側を覆うように天キャップ３４を装着する。最後に、図８に示すように、バンド３５をパレット３１及び天キャップ３４に巻き付けて締結する。バンド３５は、例えばポリプロピレン製でもよい。  The packaging device 30 is assembled as follows. A bottom tray 32 is placed on the pallet 31. Place the tray 1 on the bottom tray 32. In the present embodiment, a plurality (six) of trays 1 can be arranged on the bottom tray 32. The bottom wall 4 of the tray 1 contacts the upper surface of the bottom tray 32. The trays 1 in which the products 90 are fitted in the recesses 13 are stacked in a plurality of stages. At this time, the position of the product 90 on the tray 1 and the position of the product 90 below the tray 1 are made to coincide in the front-rear and left-right horizontal directions. Next, the side sheet 33 is disposed so as to cover the periphery of the stacked trays 1. Next, the top cap 34 is attached so as to cover the upper side of the stacked trays 1. Finally, as shown in FIG. 8, the band 35 is wound around the pallet 31 and the top cap 34 and fastened. The band 35 may be made of polypropylene, for example.

図９は、図７及び図８に示す梱包装置３０の内部の模式的な断面図である。図９に示すように、本実施の形態の梱包装置３０では、トレイ１の下の製品９０の上面と、当該トレイ１の上の製品９０の下面とが、当該トレイ１の底壁４を介して接する。なお、図７では、最上段のトレイ１に嵌め込まれた製品９１の形状が、図９に示す製品９０の形状と異なる場合の例を示す。  FIG. 9 is a schematic cross-sectional view of the inside of the packaging device 30 shown in FIGS. 7 and 8. As shown in FIG. 9, in the packaging device 30 of the present embodiment, the upper surface of the product 90 below the tray 1 and the lower surface of the product 90 above the tray 1 are interposed via the bottom wall 4 of the tray 1. Touch. FIG. 7 shows an example in which the shape of the product 91 fitted in the uppermost tray 1 is different from the shape of the product 90 shown in FIG.

本実施の形態であれば、以下の効果が得られる。主として製品９０が荷重を支持する構造になる。温度及び湿度によるトレイ１の強度変化の影響を受けることがない。梱包材の変形等による荷崩れが発生しにくくなる。  In the present embodiment, the following effects can be obtained. The product 90 mainly has a structure that supports the load. It is not affected by changes in the strength of the tray 1 due to temperature and humidity. Load collapse due to deformation of the packing material is less likely to occur.

梱包装置３０を開梱したときに、各々のトレイ１を単独で手作業により取り出し及び移動してもよい。その際に、製品９０が重量物でも、トレイ１の水平方向の中折れ変形、特にトレイ１の長手方向の途中での中折れ変形が発生しにくい。よって、製品９０同士が接触したり、トレイ１を落下させたりすることによる製品損傷が起こりにくくなる。  When the packing device 30 is unpacked, each tray 1 may be taken out and moved by hand. At that time, even if the product 90 is heavy, the horizontal deformation of the tray 1 in the horizontal direction, particularly the intermediate bending deformation in the middle of the tray 1 is unlikely to occur. Therefore, product damage due to the products 90 coming into contact with each other or dropping the tray 1 is less likely to occur.

製品９０がトレイ１の凹部１３に嵌められているので、トラック輸送時あるいは荷扱い時に発生する衝撃が、積層した段ボールの潰れによって吸収され、衝撃が緩和される。それゆえ、製品９０の損傷が発生しにくくなる。  Since the product 90 is fitted in the concave portion 13 of the tray 1, the impact generated during truck transportation or handling is absorbed by the collapse of the laminated cardboard and the impact is reduced. Therefore, the product 90 is less likely to be damaged.

図１に示すように、トレイ１の外側シート２及び中間シート３の段ボールシートは、波形の断面形状を有するフルートを備える。当該フルートの延びる方向がトレイ１の長手方向に平行である。本実施の形態であれば、このような構成により、以下の効果が得られる。トレイ１の長手方向の曲げ強度が向上する。トレイ１の水平方向の中折れ変形、特にトレイ１の長手方向の途中での中折れ変形の発生をより確実に防止できる。よって、製品９０同士が接触したり、トレイ１を落下させたりすることによる製品損傷をより確実に防止できる。外側シート２の段ボールシートのフルートが延びる方向と、中間シート３の段ボールシートのフルートが延びる方向とのいずれか一方のみが、トレイ１の長手方向に平行でもよい。その場合でも、上記効果に類似した効果が得られる。  As shown in FIG. 1, the corrugated cardboard sheets of the outer sheet 2 and the intermediate sheet 3 of the tray 1 are provided with flutes having a corrugated cross-sectional shape. The direction in which the flute extends is parallel to the longitudinal direction of the tray 1. In the present embodiment, the following effects can be obtained by such a configuration. The bending strength in the longitudinal direction of the tray 1 is improved. It is possible to more reliably prevent the horizontal deformation of the tray 1 in the horizontal direction, particularly the occurrence of the intermediate bending deformation in the middle of the longitudinal direction of the tray 1. Therefore, product damage due to the products 90 coming into contact with each other or dropping the tray 1 can be more reliably prevented. Only one of the direction in which the flute of the corrugated cardboard sheet of the outer sheet 2 extends and the direction in which the flute of the corrugated cardboard sheet of the intermediate sheet 3 extends may be parallel to the longitudinal direction of the tray 1. Even in this case, an effect similar to the above effect can be obtained.

図２に示すように、本実施の形態では、外側シート２の第一側壁５の長手方向の長さＬ２は、底壁４の長手方向の長さＬ１に等しい。外側シート２の第二側壁６の長手方向の長さＬ３は、底壁４の長手方向の長さＬ１に等しい。本実施の形態であれば、このような構成により、以下の効果が得られる。第一側壁５及び第二側壁６の曲げ剛性により、トレイ１の長手方向の曲げ強度がさらに向上する。トレイ１の水平方向の中折れ変形、特にトレイ１の長手方向の途中での中折れ変形の発生をより確実に防止できる。よって、製品９０同士が接触したり、トレイ１を落下させたりすることによる製品損傷をより確実に防止できる。図示の構成に限らず、第一側壁５の長手方向の長さＬ２が底壁４の長手方向の長さＬ１の１／２以上であり、かつ、第二側壁６の長手方向の長さＬ３が底壁４の長手方向の長さＬ１の１／２以上であれば、上記効果に類似した効果が得られる。  As shown in FIG. 2, in the present embodiment, the length L2 in the longitudinal direction of the first side wall 5 of the outer sheet 2 is equal to the length L1 in the longitudinal direction of the bottom wall 4. The length L3 in the longitudinal direction of the second side wall 6 of the outer sheet 2 is equal to the length L1 in the longitudinal direction of the bottom wall 4. In the present embodiment, the following effects can be obtained by such a configuration. The bending strength in the longitudinal direction of the tray 1 is further improved by the bending rigidity of the first side wall 5 and the second side wall 6. It is possible to more reliably prevent the horizontal deformation of the tray 1 in the horizontal direction, particularly the occurrence of the intermediate bending deformation in the middle of the longitudinal direction of the tray 1. Therefore, product damage due to the products 90 coming into contact with each other or dropping the tray 1 can be more reliably prevented. The length L2 in the longitudinal direction of the first side wall 5 is not less than 1/2 of the length L1 in the longitudinal direction of the bottom wall 4 and the length L3 in the longitudinal direction of the second side wall 6 is not limited to the illustrated configuration. Is equal to or greater than ½ of the length L1 of the bottom wall 4 in the longitudinal direction, an effect similar to the above effect can be obtained.
