Japanese Patent Laid-Open No. 10-194285 (paragraph numbers [0002] and [0003], FIGS. 5, 8, and 9)

従来の被包装体（空気調和機の室外機等）を保護する包装構造体は上記のように構成されているので、段ボールトレイ箱の上面開放部が製函作業時にどうしても外側に開いてしまうものが生じ、嵌め込み仮固定している緩衝用発泡スチロールが、製品を載せる前段階での輸送時の振動や荷扱いにより、段ボールトレイ箱から外れてしまう等の問題点があった。   A conventional packaging structure for protecting a packaged body (such as an outdoor unit of an air conditioner) is configured as described above, so that the upper surface opening part of the cardboard tray box is inevitably opened to the outside during the box making operation. There is a problem that the foamed foam for cushioning that is fitted and temporarily fixed is detached from the corrugated cardboard tray box due to vibration and handling during transportation before the product is placed.

また、技術文献１に示された段ボールトレイ箱の構造では、四つのコーナーの内側部に補強板や補強柱を段ボールで形成するため、緩衝用発泡スチロールの角部を補強板や補強柱を避けた形状にして設置しなければならない等の問題点があった。
これらの問題点を解決する包装構造体の出現が強く望まれている。
この発明は、上記に鑑み、輸送時の振動や荷扱いに強く、コーナー部における強度が維持される構造であり、且つ段ボールトレイ箱がワイヤー打ちや糊接着等を用いることなく組み立てられ、コスト削減になるとともに、使用後の開梱作業等が省力化されるような包装構造体及び包装体を提供することをその目的としている。 Further, in the structure of the corrugated cardboard tray box shown in the technical document 1, the reinforcing plate and the reinforcing column are formed by corrugated cardboard on the inner side of the four corners. There was a problem that it had to be installed in the shape.
The appearance of a packaging structure that solves these problems is strongly desired.
In view of the above, the present invention is a structure that is strong in vibration and handling during transportation and maintains the strength at the corner, and the cardboard tray box is assembled without using wire punching, glue bonding, etc., and cost reduction In addition, an object of the present invention is to provide a packaging structure and a packaging body that can save labor in unpacking after use.

この発明に係る包装構造体は、被包装体が配置される包装構造体において、段ボールトレイ箱の上部の開口部を底面部面積に対して狭面積とするために、該底面部より立ち上がる四方向の側面部の立ち上げ角度を９０度未満とし、この四方向の側面部の内向きの傾斜を維持固定するための手段を有し、前記四方向の側面部の内向きの傾斜を維持固定するための手段が、前記段ボールトレイ箱の短側面部に設けたフラップ部の延長した先端に設けられ、抜け防止のための返し部を有する凸形状部と、前記段ボールトレイ箱の長側面部に設けられ、該凸形状部が差し込まれる固定用の穴部とから構成され、前記底面部には、緩衝用の発泡スチロールが配置され、前記発泡スチロールは、前記底面部と一対の前記長側面部で挟み込まれ、かつ前記底面部と一方の前記短側面部で挟み込まれ、前記穴部は、一方の前記短側面部と接する前記発泡スチロールの面に対向する面よりも、他方の前記短側面部側の前記長側面部に設けられているものである。 Packaging structures according to the present invention, in the packaging structure which the package is disposed, in order to narrow the area of the upper opening portion of the cardboard tray box with respect to the bottom portion area, four directions that rises from the bottom surface The rising angle of the side surface portion of the four side surfaces is less than 90 degrees, and means for maintaining and fixing the inward inclination of the four side surface portions is provided, and the inward inclination of the four side surface portions is maintained and fixed. Means are provided at the extended tip of the flap portion provided on the short side surface portion of the cardboard tray box and provided on the long side surface portion of the corrugated cardboard tray box with a convex shape portion having a return portion to prevent the cardboard tray box from coming off. And a fixed foam part into which the convex part is inserted, and a foamed polystyrene foam is disposed on the bottom part, and the foamed polystyrene is sandwiched between the bottom part and the pair of long side parts. And the bottom And the hole portion is provided on the long side surface portion on the other short side surface portion side than the surface facing the surface of the polystyrene foam in contact with the one short side surface portion. It is what has been .

また、前記四側面部の内向きの傾斜を固定するため、短側面両端から延長したフラップ部の先端に凸部を設け、また、この凸部の差し込み固定用の穴部を長側面部に設け、これらを差し込み嵌合する。この凸部の差し込み先端部には、固定用穴から抜けないように返し部をもたせた構造としたものである。   Further, in order to fix the inward inclination of the four side surfaces, a convex portion is provided at the tip of the flap portion extended from both ends of the short side surface, and a hole for fixing the insertion of the convex portion is provided in the long side surface portion. These are inserted and fitted. The projecting tip portion of the convex portion has a structure in which a return portion is provided so as not to come out of the fixing hole.

この発明に係る包装構造体は、段ボールトレイ箱の上面開放部の外側に開いてしまうことを防止し、嵌め込み構造により仮固定していた緩衝用発泡スチロール等が、製品を載せる前段階での輸送時の振動や荷扱いにより、段ボールトレイ箱から外れてしまう等の問題点を解決する。
The packaging structure according to the present invention prevents the cardboard tray box from opening outside the open top surface of the corrugated cardboard tray box, and the foamed foam for cushioning temporarily fixed by the fitting structure is used when transporting the product in a stage before placing the product. This solves problems such as detachment from the cardboard tray box due to vibration and cargo handling .

FIG. 2 is a fitting explanatory view of the corrugated cardboard tray box and the shock-absorbing polystyrene foam according to the first embodiment.
FIG. 3 is a development view of the cardboard tray box according to the first embodiment.
In the figure, 1 is a corrugated cardboard tray box, 2 is a cushioning foamed polystyrene that protects the bottom surface of the packaged body, 3 is a convex part for fitting with the cardboard tray box provided on the foaming foam for cushioning, and 4 is a cushioning provided on the cardboard tray box Fitting holes with foamed polystyrene for use, 5 is a flap portion for fixing the tray box form, 6 is a folding ruled line, 11 is a long side surface portion, and 12 is a short side surface portion.

以下、図１〜図３を参照してこの発明の実施の形態１を説明する。
これらの図において、一枚の段ボール板から、折り曲げ加工により、四方向の側面部を段ボール箱の内向きに、底面部に対して開口部が狭くなるよう立ち上げ角度θが９０度未満（７０〜８５度程度）になるよう立ち上げて、長側面部１１に設置した固定用フラップ５を用いてワイヤー打ちや糊接着により短側面部１２と固定し、段ボールトレイ箱１の形態を構成する。このとき側面部１１、１２の立ち上げ角度θは、段ボール板の打ち抜き型によって抜かれた四方向の長及び短側面部１１、１２に、予めもたせておいた傾斜角によって決定されるように折り曲げ用罫線６を入れておく。
立ち上げ角度θは９０度未満であり、好ましくは７０度以上８５度以下が望ましい。８５度以上では長側面部１１の外側への倒れ傾向が大きくなり、また７０度未満では発泡スチロール２との嵌合の自由度が大きく減少する。 緩衝用発泡スチロール２の段ボールトレイ箱よりの外れ度合いは、両者間の嵌合度と摩擦係数により決定され、また嵌合度は発泡スチロール材の永久変形を生じない範囲で選ばれることが好ましい。四方向の側面部の立ち上げ角度θは、全て同一である必要はなく、上記の角度範囲内で別々であっても問題ない。 The first embodiment of the present invention will be described below with reference to FIGS.
In these figures, the rising angle θ is less than 90 degrees (70) so that the opening is narrowed with respect to the bottom surface portion, with the four side surfaces facing inward from the corrugated cardboard box by bending from a single corrugated board. The cardboard tray box 1 is configured to be fixed to the short side surface portion 12 by wire-bonding or glue bonding using the fixing flap 5 installed on the long side surface portion 11. At this time, the rising angle θ of the side surface portions 11 and 12 is bent so as to be determined by the inclination angles previously provided to the long and short side surface portions 11 and 12 in the four directions extracted by the punching die of the corrugated board. A ruled line 6 is inserted.
The rising angle θ is less than 90 degrees, preferably 70 degrees or more and 85 degrees or less. If it is 85 degrees or more, the tendency of the long side surface portion 11 to fall to the outside increases, and if it is less than 70 degrees, the degree of freedom of fitting with the expanded polystyrene 2 is greatly reduced. The degree of detachment of the cushioning foamed polystyrene 2 from the corrugated cardboard tray box is determined by the degree of fitting between them and the coefficient of friction, and the degree of fitting is preferably selected within a range that does not cause permanent deformation of the foamed polystyrene. The rising angles θ of the side portions in the four directions do not have to be the same, and there is no problem even if they are different within the above angle range.

この段ボールトレイ箱１の内側の短側面部１２の両端に併行してそれぞれ緩衝用発泡スチロール２を配置する。段ボールトレイ箱１の上部開口部が緩衝用発泡スチロール２の底面部に対して狭くなっているが、段ボールの持つ若干のバネ性により、上部開口部を押し広げながら挿入し、配置する。また、緩衝用発泡スチロール２は、被包装体１００の外観形状等により若干違う場合もあるが、段ボールトレイ箱１の底面短側面長さとほぼ同じ幅を持った直方体を基本構造とし（段ボールトレイ箱１の底面長側面部１１の長さ方向は任意とし、高さ方向は段ボールトレイ箱１の側面部の長さとほぼ同程度とする）、底面に凸部３を設け、この凸部３に嵌合するよう段ボール底面に穴４を設け、これを第一の固定とし、これと、段ボールトレイ箱１の短側面部１２と緩衝用発泡スチロール２のつき合わせにより押し合わさって固定される第二の固定により、長側面部１１に沿った方向への移動が抑制される。さらに、第三及び第四の固定として、長側面部１１も対称する２面により第二の固定と同様なつき合わせにより、お互いに押し合わさって短側面部１２に沿った方向への移動が抑制される。そして、第二〜第四の側面部は内向きに９０度未満になるよう立ち上げているため、緩衝用発泡スチロール２の三方向の側面側を挟み込むような形態となり、これにより上方向への外れも防止され、接着材等を用いずに段ボールトレイ箱１に緩衝用発泡スチロール２を嵌め込むだけの作業にて、これらを固定することが可能となる。   The shock-absorbing polystyrene foam 2 is disposed in parallel with both ends of the short side surface portion 12 inside the cardboard tray box 1. The upper opening of the cardboard tray box 1 is narrower than the bottom surface of the shock-absorbing foamed polystyrene 2, but due to the slight springiness of the cardboard, the upper opening is inserted while being expanded and placed. Further, the shock-absorbing foamed polystyrene 2 may be slightly different depending on the external shape of the package 100, but a rectangular parallelepiped having a width substantially the same as the short side surface of the bottom of the cardboard tray box 1 has a basic structure (corrugated cardboard tray box 1 The length direction of the bottom long side surface portion 11 is arbitrary, and the height direction is approximately the same as the length of the side surface portion of the cardboard tray box 1). A hole 4 is provided on the bottom surface of the corrugated cardboard, and this is used as the first fixing, and this is fixed by pressing the short side surface portion 12 of the corrugated cardboard tray box 1 and the foam foam 2 for buffering. The movement in the direction along the long side surface portion 11 is suppressed. Further, as the third and fourth fixations, the long side surface portion 11 is also symmetric with the two surfaces, and the movement in the direction along the short side surface portion 12 is suppressed by being pressed together. The And since the 2nd-4th side surface part has stood up so that it may become less than 90 degree | times inward, it becomes a form which pinches | interposes the side surface of the three directions of the foaming foam 2 for buffering, and, thereby, comes off upwards These can be prevented, and it is possible to fix them by simply inserting the foaming foam polystyrene 2 into the cardboard tray box 1 without using an adhesive or the like.

In the figure, 7 is a flap part for fixing the tray box form, 8 is a protrusion for insertion provided at the tip of the flap part 7 for fixing the tray box form, 81 is a return part of the insertion convex part, and 9 is an insert. Insertion hole portions 10 for the convex portions 10 are binding bands for binding the entire packaging structure, and 100 is a packaged body.

以下、図を参照してこの発明の実施の形態２を説明する。
図４は、発明の実施の形態１による段ボールトレイ箱１において、短側面部１２を伸ばしたフラップ７を更に延長し、先端に差し込み用凸部８を設け、また、この凸部８の差し込み固定用の穴９を長側面部１１の相対位置に設ける。凸部８は、組み立て時に穴９に容易に差し込みができるように、先端は傾斜角を持った形状とし、また、差し込んだ際に安易に抜けるのを防ぐため返し部８１を有しており、一旦差し込んだ後はこの返し部８１が穴９の縁に引っかかる構造となるように返し部８１の寸法は穴９の長さよりも若干長くする。また、この凸部８は、長側面部１１において、緩衝用発泡スチロール２の存在しないところまでフラップ７を伸ばした位置に配置し、穴９もこれに合わせた位置に配置することにより、緩衝用発泡スチロール２の形状変更等をしなくても、段ボールトレイ箱１への嵌め込みに対し、阻害しない構造となる。 The second embodiment of the present invention will be described below with reference to the drawings.
FIG. 4 shows the corrugated cardboard tray box 1 according to Embodiment 1 of the present invention, in which the flap 7 with the short side surface portion 12 extended is further extended, the insertion convex portion 8 is provided at the tip, and the convex portion 8 is inserted and fixed. Holes 9 are provided at the relative positions of the long side surface portion 11. The convex part 8 has a shape with an inclined angle so that it can be easily inserted into the hole 9 at the time of assembly, and has a return part 81 to prevent it from coming off easily when inserted, Once inserted, the dimension of the return portion 81 is slightly longer than the length of the hole 9 so that the return portion 81 is caught by the edge of the hole 9. Further, the convex portion 8 is arranged at a position where the flap 7 is extended to a place where the buffering foam polystyrene 2 does not exist in the long side surface portion 11, and the hole 9 is also arranged at a position corresponding to this, so that the foaming foam polystyrene is provided. Even if it does not change the shape of 2 etc., it becomes a structure which does not inhibit the fitting to the corrugated cardboard tray box 1.

また、このフラップ７が物流や荷扱い等による外部の作用により、差し込み部の外れやたるみが発生することが起こり得る。しかし、被包装体１００及び天面部等の全ての包装を組み合わせた包装最終形態において、結束用のバンド１０を周回させてこれらを固定する際に、結束用バンド１０をそれぞれのフラップ７を抑える位置に掛けることにより、差し込み用凸部８の外れやたるみの発生を防止することができる。   Further, the flap 7 may be detached or slack due to an external action caused by physical distribution or cargo handling. However, in the final packaging form in which all the packages such as the package body 100 and the top surface portion are combined, the binding band 10 is held at the position where the binding band 10 is held down when the binding band 10 is circulated and fixed. By hanging on, it is possible to prevent the insertion convex portion 8 from being detached or slack.

これらの発明の実施の形態は、空気調和機の室外機だけでなく、段ボールトレイ箱に段ボールトレイ箱の側面部１２と同じ幅を持った発泡スチロール２等の緩衝材等を配置するようなものであれば、何にでも適用できる。   The embodiment of these inventions is not only an outdoor unit of an air conditioner, but also a cushioning material such as polystyrene foam 2 having the same width as the side surface portion 12 of the cardboard tray box is arranged in the cardboard tray box. It can be applied to anything, if any.
