Description

本発明は、各種の製品等を梱包する梱包装置に関し、特に、冷蔵庫等の重量物を梱包するのに好適に用いられる梱包装置に関する。   The present invention relates to a packing device for packing various products and the like, and more particularly to a packing device suitably used for packing heavy items such as a refrigerator.

従来技術として、例えば特許文献１に記載されているような冷蔵庫の梱包装置が知られている。従来技術の梱包装置は、段ボール等により形成された箱体と、箱体の内部に配置された緩衝材とを備えている。箱体は、冷蔵庫を載置する底部箱体と、冷蔵庫の上部に被せる上部箱体とを備え、緩衝材は、冷蔵庫の上部及び下部の角隅をそれぞれ保護するように配置されている。また、冷蔵庫には、合成樹脂製の袋が上側から被せられ、この袋は接着等の手段により底部箱体に固着されている。   As a prior art, for example, a refrigerator packing device as described in Patent Document 1 is known. The prior art packing apparatus includes a box formed of cardboard or the like, and a cushioning material disposed inside the box. The box includes a bottom box on which the refrigerator is placed and an upper box that covers the top of the refrigerator, and the cushioning material is disposed to protect the upper and lower corners of the refrigerator. The refrigerator is covered with a synthetic resin bag from above, and this bag is fixed to the bottom box by means of adhesion or the like.

特開２００２−５３１９４号公報JP 2002-53194 A

しかしながら、上述した特許文献１に記載の従来技術では、下部の緩衝材が冷蔵庫の両側（前後または左右の両側）に配置されている。このため、例えば梱包状態の冷蔵庫を誤って落とした場合には、底部箱体の中央部、即ち、両側の緩衝材の間に位置する部分が撓み変形し易いという問題がある。特に、大型冷蔵庫においては、落下時の衝撃力が大きいので、上記問題が顕著となる。この問題の解決策としては、例えば緩衝材を大きくしたり、その個数を増やす方法が考えられる。しかしながら、この場合には、緩衝材の使用量が増加するので、コストアップが生じるだけでなく、緩衝材の廃棄処分に手間がかかることになり、環境に優しい梱包装置を実現するのが難しくなる。   However, in the prior art described in Patent Document 1 described above, the lower cushioning material is arranged on both sides (front and rear or left and right sides) of the refrigerator. For this reason, for example, when a packed refrigerator is accidentally dropped, there is a problem that the central portion of the bottom box, that is, the portion located between the cushioning materials on both sides is easily bent and deformed. In particular, in a large refrigerator, since the impact force at the time of dropping is large, the above problem becomes significant. As a solution to this problem, for example, a method of enlarging the cushioning material or increasing the number thereof can be considered. However, in this case, the amount of use of the cushioning material increases, which not only increases the cost, but also takes time to dispose of the cushioning material, making it difficult to realize an environmentally friendly packaging device. .

本発明は、上述のような課題を解決するためになされたもので、従来技術と比較して緩衝材の使用量を増加させることなく、落下時の衝撃等に対して被梱包物を保護する機能を向上させることが可能な梱包装置を提供することを目的とする。   The present invention has been made in order to solve the above-described problems, and protects an object to be packed against an impact or the like at the time of dropping without increasing the amount of use of a cushioning material as compared with the prior art. An object of the present invention is to provide a packaging device capable of improving the function.

本発明に係る梱包装置は、被梱包物を下側から覆うための底面部を有し、被梱包物の下側に配置される下部包装材と、下部包装材の底面部上に配置され、被梱包物を下側から支持する下部緩衝材と、被梱包物の上部に設けられる上部緩衝材と、上部緩衝材を上側から覆う上部包装材と、被梱包物の側面部を覆う外装材と、下部包装材の底面部に切込みを入れて当該底面部の一部を上向きに折曲げることにより形成され、下部緩衝材と異なる位置で底面部から上向きに突出して被梱包物に当接する折曲げ片と、を備えている。   The packaging device according to the present invention has a bottom surface part for covering the article to be packed from the lower side, and is arranged on the lower packaging material arranged on the lower side of the article to be packaged, and on the bottom part of the lower packaging material, A lower cushioning material that supports the object to be packaged from below, an upper cushioning material provided at the top of the object to be packaged, an upper packaging material that covers the upper cushioning material from above, and an exterior material that covers the side surface of the object to be packaged Bending formed by cutting a bottom portion of the lower packaging material and bending a part of the bottom portion upward, protruding upward from the bottom portion at a position different from the lower cushioning material, and contacting the package And a piece.

本発明によれば、下部緩衝材の底面部の一部を上向きに折曲げることにより、折曲げ片を形成することができる。折曲げ片は、下部緩衝材と異なる位置で下部包装材の底面部と被梱包物との間に介在し、下部包装材を補強することができる。この結果、例えば緩衝材を追加しなくても、落下等の衝撃により下部包装材が変形するのを折曲げ片により抑制し、被梱包物を衝撃から保護することができる。従って、従来技術と比較して緩衝材の使用量を増加させることなく、より高い緩衝性能を有する梱包装置を実現することができる。   According to the present invention, a bent piece can be formed by bending a part of the bottom surface portion of the lower cushioning material upward. The bent piece is interposed between the bottom surface portion of the lower packaging material and the article to be packed at a position different from the lower cushioning material, and can reinforce the lower packaging material. As a result, for example, without adding a cushioning material, it is possible to suppress the lower packaging material from being deformed by an impact such as dropping by the bent piece, and to protect the packaged item from the impact. Therefore, it is possible to realize a packaging device having higher cushioning performance without increasing the amount of cushioning material used as compared with the prior art.

The lower cushioning material 15 is formed as an elongated pedestal-shaped member, and a planar support surface portion 15 a that abuts the lower surface of the refrigerator 1 is formed on the upper portion of the lower cushioning material 15. As will be described later, for example, one lower cushioning material 15 is disposed on each of the left and right sides of the refrigerator 1 (preferably, the left end and the right end of the lower surface of the refrigerator 1) and is fitted inside the lower packaging material 11 And interposed between the bottom surface portion 12 and the refrigerator 1 to support the refrigerator 1 from below.

上部緩衝材１６は、冷蔵庫１の上部側を衝撃等から保護するもので、例えば下部緩衝材１５と同様の材料により細長い部材として形成されている。上部緩衝材１６は、後述のように、冷蔵庫１の上部の左右両側に１個ずつ設けられ、冷蔵庫１の上部側の角隅を覆った状態に保持される。上部包装材１７は、例えば段ボールシートを折曲げることにより、下側が開口した箱形状に形成され、下部包装材１１とほぼ同様の外形寸法を有している。そして、上部包装材１７は、各上部緩衝材１６を上側から覆った状態で冷蔵庫１の上部に設けられる。外装材１８は、冷蔵庫１、下部包装材１１及び上部緩衝材１６の側面部を覆うもので、例えば段ボールシート等により四角形の筒状に形成され、上下方向の両側が開口している。   The upper cushioning material 16 protects the upper side of the refrigerator 1 from an impact or the like, and is formed as an elongated member with the same material as the lower cushioning material 15, for example. As will be described later, one upper cushioning material 16 is provided on each of the left and right sides of the upper portion of the refrigerator 1 and is held in a state of covering the upper corners of the refrigerator 1. The upper packaging material 17 is formed in a box shape having an opening on the lower side, for example, by bending a corrugated cardboard sheet, and has substantially the same outer dimensions as the lower packaging material 11. And the upper packaging material 17 is provided in the upper part of the refrigerator 1 in the state which covered each upper buffer material 16 from the upper side. The exterior material 18 covers the side surfaces of the refrigerator 1, the lower packaging material 11, and the upper cushioning material 16. The exterior material 18 is formed in a rectangular tube shape by, for example, a corrugated cardboard sheet or the like, and is open on both sides in the vertical direction.

次に、図２を参照して、下部包装材１１の底面部１２に設けられた折曲げ片１４について説明する。図２は、図１中の下部包装材を単体で示す斜視図である。折曲げ片１４は、下部包装材１１の底面部１２に切込み１４ａを入れて当該底面部１２の一部を上向きに折曲げることにより形成されている。折曲げ片１４は、例えば前後方向に細長く延びた四角形の筒状に形成され、四角形の断面形状を有している。そして、折曲げ片１４は、底面部１２から上向きに規定の高さ寸法をもって突出し、平坦な上面部を有している。   Next, with reference to FIG. 2, the bending piece 14 provided in the bottom face part 12 of the lower packaging material 11 is demonstrated. FIG. 2 is a perspective view showing the lower packaging material in FIG. 1 alone. The bent piece 14 is formed by making a cut 14 a in the bottom surface portion 12 of the lower packaging material 11 and bending a part of the bottom surface portion 12 upward. The bent piece 14 is formed in, for example, a rectangular tube shape elongated in the front-rear direction, and has a rectangular cross-sectional shape. The bent piece 14 protrudes upward from the bottom surface portion 12 with a specified height dimension, and has a flat top surface portion.

また、折曲げ片１４は、後述の図４に示すように、下部緩衝材１５を下部包装材１１の内側に嵌め込んだ状態において、下部緩衝材１５と異なる位置に２個形成されている。より具体的に述べると、各折曲げ片１４は、左右の下部緩衝材１５の間となり、かつ、各下部緩衝材１５よりも底面部１２の中央寄りとなる位置に配置されている。また、２個の折曲げ片１４は、冷蔵庫１の左右方向の中心位置に対して左右対称となるように配置されている。各折曲げ片１４の高さ寸法は、下部包装材１１の底面部１２から下部緩衝材１５の支持面部１５ａまでの高さ寸法と等しくなるように設定されている。   Further, as shown in FIG. 4 described later, two bent pieces 14 are formed at positions different from the lower cushioning material 15 in a state where the lower cushioning material 15 is fitted inside the lower packaging material 11. More specifically, each bent piece 14 is disposed between the left and right lower cushioning materials 15 and at a position closer to the center of the bottom surface portion 12 than each lower cushioning material 15. Further, the two bent pieces 14 are arranged so as to be symmetric with respect to the center position in the left-right direction of the refrigerator 1. The height dimension of each bent piece 14 is set to be equal to the height dimension from the bottom surface portion 12 of the lower packaging material 11 to the support surface portion 15a of the lower cushioning material 15.

次に、図３及び図４を参照して、梱包装置１０により冷蔵庫１を梱包する場合の手順について説明する。図３は、本発明の実施の形態１において、梱包装置により冷蔵庫を梱包して梱包製品を組立てた状態を示す斜視図である。図４は、図３中の梱包製品の下部を示す縦断面図である。冷蔵庫１の梱包時には、まず、床面等に載置した下部包装材１１の上側に２個の下部緩衝材１５を配置する。具体的には、各下部緩衝材１５を下部包装材１１の側壁部１３ａ〜１３ｄの内側に嵌め込んで底面部１２上に配置する。そして、冷蔵庫１を各下部緩衝材１５上に載置し、冷蔵庫１の下面を各下部緩衝材１５の支持面部１５ａにそれぞれ当接させる。   Next, with reference to FIG.3 and FIG.4, the procedure in the case of packing the refrigerator 1 with the packing apparatus 10 is demonstrated. FIG. 3 is a perspective view showing a state in which the refrigerator is packed by the packing device and the packed product is assembled in the first embodiment of the present invention. 4 is a longitudinal sectional view showing a lower part of the packaged product in FIG. When the refrigerator 1 is packed, first, two lower cushioning materials 15 are arranged on the upper side of the lower packaging material 11 placed on the floor or the like. Specifically, each lower cushioning material 15 is fitted on the inner side of the side wall portions 13 a to 13 d of the lower packaging material 11 and arranged on the bottom surface portion 12. And the refrigerator 1 is mounted on each lower buffer material 15, and the lower surface of the refrigerator 1 is made to contact | abut to the support surface part 15a of each lower buffer material 15, respectively.

このとき、左側の下部緩衝材１５は、図４に示すように、下部包装材１１の側壁部１３ｄに沿って前後方向に伸張し、支持面部１５ａが冷蔵庫１の左角隅の下面に対して前端から後端まで当接した状態に保持される。また、右側の下部緩衝材１５は、下部包装材１１の側壁部１３ｂに沿って前後方向に伸張し、支持面部１５ａが冷蔵庫１の右角隅の下面に対して前端から後端まで当接した状態に保持される。この状態で、２個の下部緩衝材１５は、底面部１２の４辺のうち互いに平行な２辺に沿ってそれぞれ配置され、底面部１２の４隅で冷蔵庫１を支持している。また、２個の折曲げ片１４は、各下部緩衝材１５の間で冷蔵庫１の下面に当接した状態となる。   At this time, as shown in FIG. 4, the left lower cushioning material 15 extends in the front-rear direction along the side wall portion 13 d of the lower packaging material 11, and the support surface portion 15 a is against the lower surface of the left corner of the refrigerator 1. It is held in contact with the front end to the rear end. Further, the right lower cushioning material 15 extends in the front-rear direction along the side wall portion 13 b of the lower packaging material 11, and the support surface portion 15 a is in contact with the lower surface of the right corner of the refrigerator 1 from the front end to the rear end. Retained. In this state, the two lower cushioning materials 15 are disposed along two sides parallel to each other among the four sides of the bottom surface portion 12, and support the refrigerator 1 at the four corners of the bottom surface portion 12. Further, the two bent pieces 14 are in contact with the lower surface of the refrigerator 1 between the lower cushioning materials 15.

次に、冷蔵庫１の上部の左角隅及び右角隅に上部緩衝材１６をそれぞれ配置し、各上部緩衝材１６の上側から上部包装材１７を被せる。これにより、各上部緩衝材１６は、上部包装材１７の内側に嵌め込まれた状態となる。続いて、外装材１８を上部包装材１７の上側から被せることにより、外装材１８が冷蔵庫１、下部包装材１１及び上部包装材１７の全てを外側から包むようにする。そして、図３に示すように、複数のバンド２０を用いて下部包装材１１、上部包装材１７及び外装材１８を締結することにより、冷蔵庫１が梱包装置１０により梱包された梱包製品３０を完成する。   Next, the upper cushioning material 16 is disposed at the upper left corner and the right corner of the refrigerator 1, and the upper packaging material 17 is covered from the upper side of each upper cushioning material 16. Thereby, each upper shock absorbing material 16 will be in the state fitted by the inner side of the upper packaging material 17. FIG. Subsequently, by covering the outer packaging material 18 from the upper side of the upper packaging material 17, the outer packaging material 18 wraps all of the refrigerator 1, the lower packaging material 11 and the upper packaging material 17 from the outside. Then, as shown in FIG. 3, the lower packaging material 11, the upper packaging material 17, and the exterior material 18 are fastened using a plurality of bands 20, thereby completing the packed product 30 in which the refrigerator 1 is packed by the packing device 10. To do.

このように、冷蔵庫１を梱包した状態において、各折曲げ片１４は、左右の下部緩衝材１５の間で冷蔵庫１の下面と下部包装材１１の底面部１２との間に介在し、底面部１２の中央部を補強することができる。この結果、例えば落下等により梱包製品３０に衝撃が加わった場合でも、冷蔵庫１及び下部包装材１１の中央部が撓んで変形するのを各折曲げ片１４により抑制し、冷蔵庫１を衝撃等から保護することができる。これにより、従来技術と比較して緩衝材の使用量を増加させなくても、より高い強度の梱包装置１０を実現することができる。   Thus, in the state which packed the refrigerator 1, each bending piece 14 is interposed between the lower surface of the refrigerator 1 and the bottom face part 12 of the lower packaging material 11 between the left and right lower cushioning materials 15, and the bottom face part. Twelve central portions can be reinforced. As a result, even when an impact is applied to the packaged product 30 due to, for example, dropping, the bent portions 14 prevent the central portion of the refrigerator 1 and the lower packaging material 11 from being bent and deformed. Can be protected. Thereby, even if it does not increase the usage-amount of a buffer material compared with a prior art, the packaging apparatus 10 of higher intensity | strength is realizable.

即ち、従来技術の梱包装置では、下部包装材１１の中央部が変形するのを防止するために、例えば左右の下部緩衝材を大きくしたり、下部包装材１１の中央部に別個の緩衝材を追加することが一般的であった。これに対し、本実施の形態によれば、下部包装材１１の底面部１２の一部を利用して折曲げ片１４を形成することができる。従って、緩衝材の使用量を従来技術と同等かそれ以下に削減しつつ、梱包装置１０の緩衝性能を高めることができ、高性能かつ低コストで環境に優しい梱包装置１０を提供することができる。   That is, in the conventional packing apparatus, in order to prevent the central portion of the lower packaging material 11 from being deformed, for example, the left and right lower cushioning materials are enlarged, or separate cushioning materials are provided in the central portion of the lower packaging material 11. It was common to add. On the other hand, according to this Embodiment, the bending piece 14 can be formed using a part of bottom face part 12 of the lower packaging material 11. FIG. Therefore, it is possible to improve the buffering performance of the packing device 10 while reducing the amount of use of the cushioning material to be equal to or less than that of the conventional technology, and it is possible to provide a high-performance, low-cost and environmentally friendly packing device 10. .

特に、本実施の形態では、冷蔵庫１（下部包装材１１）の左右両側に配置した下部緩衝材１５の間に、２個の折曲げ片１４を左右方向に離間した状態で配置し、これらの下部緩衝材１５と折曲げ片１４とを前後方向に伸張させている。また、折曲げ片１４の上面部と下部緩衝材１５の支持面部１５ａとを同じ高さ寸法に形成している。さらに、各下部緩衝材１５により冷蔵庫１の４隅を支持している。この結果、下部緩衝材１５と折曲げ片１４とを前後方向及び左右方向の広い範囲にわたって冷蔵庫１の下面に均等に当接させることができる。これにより、落下等による衝撃を下部包装材１１の全体に分散させ、中央部に加わる負荷を効率よく軽減することができる。また、折曲げ片１４の断面形状を四角形に形成することにより、折曲げ片１４の上面部を平坦に形成し、折曲げ片１４と冷蔵庫１とを広い面積で接触させることができる。   In particular, in the present embodiment, two folded pieces 14 are arranged in a state of being separated in the left-right direction between the lower cushioning materials 15 arranged on the left and right sides of the refrigerator 1 (lower packaging material 11). The lower cushioning material 15 and the bent piece 14 are extended in the front-rear direction. Moreover, the upper surface part of the bending piece 14 and the support surface part 15a of the lower shock absorbing material 15 are formed in the same height dimension. Furthermore, the four corners of the refrigerator 1 are supported by each lower cushioning material 15. As a result, the lower cushioning material 15 and the bent piece 14 can be evenly brought into contact with the lower surface of the refrigerator 1 over a wide range in the front-rear direction and the left-right direction. Thereby, the impact by dropping etc. can be disperse | distributed to the whole lower packaging material 11, and the load added to a center part can be reduced efficiently. Moreover, by forming the cross-sectional shape of the bent piece 14 into a quadrangle, the upper surface portion of the bent piece 14 can be formed flat, and the bent piece 14 and the refrigerator 1 can be brought into contact with each other over a wide area.

次に、図５及び図６を参照して、本発明の実施の形態２について説明する。本実施の形態の特徴は、前記実施の形態１と個数、位置及び断面形状が異なる折曲げ片を例示し、圧縮機の下側に折曲げ片を配置したことにある。図５は、本発明の実施の形態２よる梱包装置の下部包装材を示す図２と同様の斜視図である。図６は、図５中の下部包装材を用いた梱包製品の下部を示す縦断面図である。なお、図６は、前記図４と直交する方向での断面を示している。 Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS. The feature of the present embodiment is that a bent piece having a different number, position, and cross-sectional shape from that of the first embodiment is exemplified, and the bent piece is disposed on the lower side of the compressor. FIG. 5 is a perspective view similar to FIG. 2 showing the lower packaging material of the packaging device according to Embodiment 2 of the present invention. 6 is a longitudinal sectional view showing a lower part of a packaged product using the lower packaging material in FIG. FIG. 6 shows a cross section in a direction orthogonal to FIG.

本実施の形態よる梱包装置の下部包装材４１は、図５に示すように、前記実施の形態１と同様の底面部１２及び側壁部１３ａ，１３ｂ，１３ｃ，１３ｄと、折曲げ片４２とを備えている。そして、折曲げ片４２は、底面部１２に切込み４２ａを入れて当該底面部１２の一部を上向きに折曲げることにより形成され、各下部緩衝材１５の間となる位置に底面部１２から上向きに突出している。但し、本実施の形態の折曲げ片４２は、三角形の断面形状を有し、例えば３個形成されている。また、３個のうち少なくとも１個の折曲げ片４２は、図６に示すように、冷蔵庫１の圧縮機３の下側に配置されている。   As shown in FIG. 5, the lower packaging material 41 of the packaging device according to the present embodiment includes a bottom surface portion 12 and side wall portions 13a, 13b, 13c, and 13d similar to those of the first embodiment, and a bent piece 42. I have. The bent piece 42 is formed by making a cut 42 a in the bottom surface portion 12 and bending a part of the bottom surface portion 12 upward, and upward from the bottom surface portion 12 to a position between the lower cushioning materials 15. Protruding. However, the bent piece 42 of the present embodiment has a triangular cross-sectional shape, for example, three pieces are formed. Further, at least one of the three bent pieces 42 is disposed on the lower side of the compressor 3 of the refrigerator 1 as shown in FIG. 6.

このように構成される本実施の形態によれば、前記実施の形態１と同様の効果に加えて、次のような作用効果を得ることができる。まず、折曲げ片４２を三角形状とすることにより、例えば実施の形態１と比較して、折曲げ片４２を形成するのに必要な切込み４２ａの面積を小さくすることができる。これにより、底面部１２に形成される穴の開口面積を最小限にすることができるので、例えば梱包製品３０を引き摺って運ぶ場合等に対して、底面部１２の強度を向上させることができる。   According to the present embodiment configured as described above, in addition to the same effects as those of the first embodiment, the following operational effects can be obtained. First, by making the bent piece 42 into a triangular shape, for example, the area of the notch 42a required to form the bent piece 42 can be reduced as compared with the first embodiment. Thereby, since the opening area of the hole formed in the bottom face part 12 can be minimized, the strength of the bottom face part 12 can be improved, for example, when the packaged product 30 is dragged and carried.

一方、圧縮機３は、冷蔵庫１の構成部品の中でも重量が大きいので、梱包製品３０を落下させた場合には、特に圧縮機３の位置で下部包装材４１が変形し易い。これに対し、本実施の形態では、例えば１個の折曲げ片４２を圧縮機３の下側に配置しているので、この折曲げ片４２により変形し易い部位を効果的に補強することができ、落下時等における冷蔵庫１の保護機能を高めることができる。   On the other hand, since the compressor 3 is heavy among the components of the refrigerator 1, the lower packaging material 41 is likely to be deformed particularly at the position of the compressor 3 when the packed product 30 is dropped. On the other hand, in the present embodiment, for example, one bent piece 42 is disposed below the compressor 3, so that the portion easily deformed by the bent piece 42 can be effectively reinforced. It is possible to enhance the protection function of the refrigerator 1 when it is dropped.

なお、前記実施の形態１，２では、折曲げ片１４，４２の一例を記載したが、本発明において、折曲げ片の断面形状、寸法、個数及び配置は、被梱包物の形状、重量分布等に応じて適宜設定すればよいものであり、実施の形態１，２に限定されるものではない。また、本発明では、複数個の折曲げ片を形成した場合おいて、一部の折曲げ片の寸法、形状等を他の折曲げ片と異ならせる構成としてもよい。一例を挙げれば、１つの下部包装材に２種類の折曲げ片１４，４２を設けてもよい。   In the first and second embodiments, an example of the bent pieces 14 and 42 has been described. However, in the present invention, the cross-sectional shape, dimensions, number, and arrangement of the bent pieces are the shape of the packaged items and the weight distribution. However, the present invention is not limited to the first and second embodiments. In the present invention, when a plurality of bent pieces are formed, the size, shape, etc. of some of the bent pieces may be different from those of other bent pieces. For example, two types of bent pieces 14 and 42 may be provided in one lower packaging material.

また、前記実施の形態１では、下部緩衝材１５を、冷蔵庫１の左右方向の両側に１個ずつ配置する場合を例示した。しかし、本発明はこれに限らず、下部緩衝材は、下部包装材の底面部１２において水平方向の一側と他側に少なくとも１個ずつ配置すればよい。具体的に述べると、下部緩衝材は、例えば冷蔵庫１の前後方向の両側（好ましくは、冷蔵庫１の下面の前端部及び後端部）に１個ずつ配置してもよいし、冷蔵庫１の４辺に１個ずつ配置してもよい。また、下部緩衝材は、冷蔵庫１の４隅に１個ずつ配置してもよい。更に言えば、下部緩衝材は、１箇所に２個以上の複数個ずつ配置してもよく、例えば冷蔵庫１の４辺に３個ずつ配置してもよい。   Moreover, in the said Embodiment 1, the case where the lower buffer material 15 was arrange | positioned 1 each on the both sides of the left-right direction of the refrigerator 1 was illustrated. However, the present invention is not limited thereto, and at least one lower cushioning material may be disposed on one side and the other side in the horizontal direction on the bottom surface portion 12 of the lower packaging material. Specifically, for example, one lower cushioning material may be disposed on each side of the refrigerator 1 in the front-rear direction (preferably, the front end portion and the rear end portion of the lower surface of the refrigerator 1). One piece may be arranged on each side. Further, one lower cushioning material may be arranged at each of the four corners of the refrigerator 1. Further, two or more lower cushioning materials may be arranged at one location, for example, three at the four sides of the refrigerator 1.

また、前記実施の形態１，２では、段ボールシートを折曲げることにより、下部包装材１１，４１、上部包装材１７及び外装材１８を形成したが、本発明は、これらの部材を段ボールシート以外のシート状の材料により形成してもよい。また、実施の形態１，２では、被梱包として、圧縮機３を有する冷蔵庫１を例示したが、本発明は、冷蔵庫以外の機器、製品等を含む各種の被梱包物に適用されるものである。   In the first and second embodiments, the lower packaging materials 11 and 41, the upper packaging material 17 and the exterior material 18 are formed by bending the corrugated cardboard sheet. However, in the present invention, these members are other than the corrugated cardboard sheet. You may form by the sheet-like material. Moreover, in Embodiment 1, 2, although the refrigerator 1 which has the compressor 3 was illustrated as to-be-packaged, this invention is applied to various to-be-packaged goods including apparatuses, products, etc. other than a refrigerator. is there.
