　図３は、本実施の形態１に係る包装体１００で包装される空気調和機の室外機２００を示す斜視図である。図４は、図３に示す空気調和機の室外機２００の内部構造を示す斜視図である。図５は、図３に示す空気調和機の室外機２００の外郭パネル１１を示す斜視図である。図６は、図３に示す空気調和機の室外機２００の側面パネル１２を示す正面図である。 FIG. 3 is a perspective view showing an outdoor unit 200 of an air conditioner packaged in the package 100 according to the first embodiment. FIG. 4 is a perspective view showing the internal structure of the outdoor unit 200 of the air conditioner shown in FIG. FIG. 5 is a perspective view showing an outer panel 11 of the outdoor unit 200 of the air conditioner shown in FIG. FIG. 6 is a front view showing a side panel 12 of the outdoor unit 200 of the air conditioner shown in FIG.
　室外機２００は、図３に示すように、外郭パネル１１と、側面パネル１２と、天面パネル１３と、底板１４とで外郭が構成されている。側面パネル１２は、室外機２００の右側面に配置されるものである。天面パネル１３は室外機２００の天面に配置されるものである。底板１４は、室外機２００の底面に配置され、内部の部品が載置されるものである。外郭パネル１１は、図５に示すように前面部１１ａと側面部１１ｂとで構成されており、室外機２００の前面および左側面に配置されるものである。 As shown in FIG. 3, the outdoor unit 200 has an outer shell composed of an outer shell panel 11, a side panel 12, a top panel 13, and a bottom plate 14. The side panel 12 is arranged on the right side surface of the outdoor unit 200. The top panel 13 is arranged on the top surface of the outdoor unit 200. The bottom plate 14 is arranged on the bottom surface of the outdoor unit 200 on which internal parts are placed. As shown in FIG. 5, the outer panel 11 is composed of a front surface portion 11a and a side surface portion 11b, and is arranged on the front surface and the left side surface of the outdoor unit 200.
　室外機２００の内部には、図４に示すように、鉛直方向に仕切板２１が設けられており、この仕切板２１によって室外機２００の内部が、左側の熱交換器室２００Ａと右側の機械室２００Ｂとに分割されている。熱交換器室２００Ａには、熱交換器１５と、プロペラファン１６と、モーター保持支柱１７とが設けられている。また、機械室２００Ｂには、圧縮機１８と、冷媒配管１９と、電気品箱２０とが設けられている。 As shown in FIG. 4, a partition plate 21 is provided inside the outdoor unit 200 in the vertical direction, and the partition plate 21 causes the inside of the outdoor unit 200 to be the heat exchanger room 200A on the left side and the machine on the right side. It is divided into a room 200B. The heat exchanger room 200A is provided with a heat exchanger 15, a propeller fan 16, and a motor holding column 17. Further, the machine room 200B is provided with a compressor 18, a refrigerant pipe 19, and an electric component box 20.
　熱交換器１５は、蒸発器または凝縮器として機能し、空気と冷媒との間で熱交換を行い、冷媒を蒸発ガス化または凝縮液化するものである。プロペラファン１６は、ファンモータ（図示せず）によって回転駆動させられ、熱交換器１５に空気を供給するものである。モーター保持支柱１７は、熱交換器１５に取り付けられ、プロペラファン１６が取り付けられたファンモータを保持するものである。 The heat exchanger 15 functions as an evaporator or a condenser, exchanges heat between air and a refrigerant, and vaporizes or condenses the refrigerant. The propeller fan 16 is rotationally driven by a fan motor (not shown) to supply air to the heat exchanger 15. The motor holding column 17 is attached to the heat exchanger 15 and holds the fan motor to which the propeller fan 16 is attached.
　圧縮機１８は、冷媒を吸入し、その冷媒を圧縮して高温高圧の状態にするものである。冷媒配管１９は、圧縮機１８と熱交換器１５とを接続し、内部に冷媒が流れるものである。電気品箱２０は、各種電気品などを収容するものであり、例えば制御装置およびヒートシンクを収容している。 The compressor 18 sucks in the refrigerant and compresses the refrigerant into a high temperature and high pressure state. The refrigerant pipe 19 connects the compressor 18 and the heat exchanger 15, and the refrigerant flows inside. The electrical component box 20 houses various electrical components and the like, and houses, for example, a control device and a heat sink.
　図５および図６に示すように、熱交換器室２００Ａ側に配置されている外郭パネル１１の側面部１１ｂには、熱交換器１５に供給される熱交換用の空気を導入する吸入口１１ｂａが複数形成されている。また、機械室２００Ｂ側に配置されている側面パネル１２には、電気品箱２０に供給される冷却用の空気を導入する吸入口１２ａが一つのみ形成されている。そのため、外郭パネル１１の側面部１１ｂの方が側面パネル１２よりも開口面積の合計が大きく、外郭パネル１１の側面部１１ｂの方が側面パネル１２よりも耐圧強度が弱くなっている。 As shown in FIGS. 5 and 6, the suction port 11ba for introducing the heat exchange air supplied to the heat exchanger 15 into the side surface portion 11b of the outer panel 11 arranged on the heat exchanger chamber 200A side. Are formed in plurality. Further, the side panel 12 arranged on the machine room 200B side is formed with only one suction port 12a for introducing cooling air supplied to the electric component box 20. Therefore, the side surface portion 11b of the outer shell panel 11 has a larger total opening area than the side panel 12, and the side surface portion 11b of the outer shell panel 11 has a weaker pressure resistance than the side panel 12.
　また、図４に示すように、室外機２００では、熱交換器１５の熱交換率を向上させるため、熱交換器室２００Ａが機械室２００Ｂよりも広くなっており、仕切板２１は、室外機２００の左右中央よりも右側に配置されている。そのため、室外機２００の段積み時には、室外機２００の機械室２００Ｂ側にかかる荷重を仕切板２１が受けている。 Further, as shown in FIG. 4, in the outdoor unit 200, in order to improve the heat exchange rate of the heat exchanger 15, the heat exchanger room 200A is wider than the machine room 200B, and the partition plate 21 is the outdoor unit. It is located on the right side of the center of the left and right sides of the 200. Therefore, when the outdoor unit 200 is stacked, the partition plate 21 receives the load applied to the machine room 200B side of the outdoor unit 200.
　以上より、室外機２００の熱交換器室２００Ａ側は、機械室２００Ｂ側に比べて耐圧強度が弱い構造となっているため、倉庫保管時および輸送運搬時などには、室外機２００の熱交換器室２００Ａ側を補強する必要がある。 From the above, since the heat exchanger room 200A side of the outdoor unit 200 has a structure in which the withstand voltage strength is weaker than that of the machine room 200B side, the heat exchange of the outdoor unit 200 is performed during warehouse storage and transportation. It is necessary to reinforce the equipment room 200A side.

　補強段ボール７には、図７に示すように、上端から３０ｍｍ程度下方の位置、および、下端から３０ｍｍ程度上方の位置に、水平方向に沿って折り曲げ線７ａがそれぞれ設けられている。 As shown in FIG. 7, the reinforcing corrugated cardboard 7 is provided with bending lines 7a along the horizontal direction at a position about 30 mm below the upper end and a position about 30 mm above the lower end.
　補強段ボール７は、図８に示すように、正面視して上端および下端が折り曲げ線７ａに沿ってそれぞれ直角に折り曲げられ、折り曲げ部７ｃが上下に形成されている。そして、補強段ボール７は、図９に示すように、上端側に形成された折り曲げ部７ｃが天面緩衝材３と接触するように、および、下端側に形成された折り曲げ部７ｃが底面緩衝材４と接触するように挟まれることで、固定される。 As shown in FIG. 8, the upper end and the lower end of the reinforced corrugated cardboard 7 are bent at right angles along the bending line 7a, and the bent portions 7c are formed vertically. Then, as shown in FIG. 9, the reinforcing corrugated cardboard 7 has a bent portion 7c formed on the upper end side in contact with the top cushioning material 3 and a bent portion 7c formed on the lower end side as a bottom cushioning material. It is fixed by being sandwiched so as to come into contact with 4.
　また、補強段ボール７には、天面から荷重がかかった場合の補強用として、上部支持部７ｄおよび下部支持部７ｅが形成されている。上部支持部７ｄは、断面Ｌ字状の角部７ｂと折り曲げ部７ｃとを有し、折り曲げ部７ｃの上面が天面緩衝材３の下面と接触し、角部７ｂが室外機２００の天面からの荷重を受けるように形成されている。また、下部支持部７ｅは、断面Ｌ字状の角部７ｂと折り曲げ部７ｃとを有し、折り曲げ部７ｃが底面緩衝材４の上面と接触し、角部７ｂが室外機２００の天面からの荷重を底面緩衝材４の上面で支えるように形成されている。なお、角部７ｂは、厳密に断面Ｌ字状でなくてもよく、ほぼ断面Ｌ字状であればよい。 Further, the reinforced corrugated cardboard 7 is formed with an upper support portion 7d and a lower support portion 7e for reinforcement when a load is applied from the top surface. The upper support portion 7d has a corner portion 7b having an L-shaped cross section and a bent portion 7c, the upper surface of the bent portion 7c is in contact with the lower surface of the top cushioning material 3, and the corner portion 7b is the top surface of the outdoor unit 200. It is formed to receive the load from. Further, the lower support portion 7e has a corner portion 7b having an L-shaped cross section and a bent portion 7c, the bent portion 7c comes into contact with the upper surface of the bottom cushioning material 4, and the corner portion 7b is from the top surface of the outdoor unit 200. Is formed so as to support the load of the bottom surface cushioning material 4. The corner portion 7b does not have to be strictly L-shaped in cross section, and may be substantially L-shaped in cross section.
　それにより、天面緩衝材３と底面緩衝材４との間で補強段ボール７が突っ張り、補強段ボール７が支柱の役割を果たす。 As a result, the reinforcing corrugated cardboard 7 is stretched between the top cushioning material 3 and the bottom cushioning material 4, and the reinforcing corrugated cardboard 7 acts as a support.
　図１０は、本実施の形態１に係る包装体１００の補強段ボール７の変形例を示す斜視図である。
　図１０に示すように、補強段ボール７を正面視して左右の側部にそれぞれ折り曲げ部７ｃを形成してもよい。それら折り曲げ部７ｃは、補強段ボール７の左端から離れた位置および右端から離れた位置のそれぞれに、鉛直方向に沿って折り曲げ線が設けられており、左端および右端が折り曲げ線に沿ってそれぞれ直角に折り曲げられて形成されている。このように、補強段ボール７の左右の側部にそれぞれ折り曲げ部７ｃを形成することで、補強段ボール７の剛性を上げ、補強段ボール７の耐圧強度を増加させることができる。 FIG. 10 is a perspective view showing a modified example of the reinforced corrugated cardboard 7 of the packaging body 100 according to the first embodiment.
As shown in FIG. 10, when the reinforcing corrugated cardboard 7 is viewed from the front, bent portions 7c may be formed on the left and right side portions, respectively.

It is sandwiched and fixed by the material 3 and the bottom cushioning material 4. Further, the bent portion 7c of the upper support portion 7d is formed so that the upper surface is in contact with the lower surface of the top cushioning material 3, and the bent portion 7c of the lower support portion 7e has a lower surface of the upper surface of the bottom cushioning material 4. It is formed to make contact.
　本実施の形態１に係る包装体１００によれば、上端が折り曲げられて形成された折り曲げ部７ｃを有する上部支持部７ｄと、下端が折り曲げられて形成された折り曲げ部７ｃを有する下部支持部７ｅと、を備えた補強段ボール７を有している。そして、補強段ボール７は、天面緩衝材３および底面緩衝材４によって挟まれて固定されるものであり、上部支持部７ｄの折り曲げ部７ｃは、上面が天面緩衝材３の下面と接触するように形成されており、下部支持部７ｅの折り曲げ部７ｃは、下面が底面緩衝材４の上面と接触するように形成されているものである。そのため、補強段ボール７は、上部支持部７ｄで室外機２００の天面からの荷重を受け、下部支持部７ｅで室外機２００の天面からの荷重を底面緩衝材４の上面で突っ張らせるようになっており、支柱の役割を果たす。その結果、耐圧強度を確保しつつ、部品点数を削減することができる。 According to the package 100 according to the first embodiment, the upper support portion 7d having a bent portion 7c formed by bending the upper end and the lower support portion 7e having a bent portion 7c formed by bending the lower end. The reinforced corrugated cardboard 7 is provided with the above. The reinforcing corrugated cardboard 7 is sandwiched and fixed by the top cushioning material 3 and the bottom cushioning material 4, and the upper surface of the bent portion 7c of the upper support portion 7d comes into contact with the lower surface of the top cushioning material 3. The bent portion 7c of the lower support portion 7e is formed so that the lower surface is in contact with the upper surface of the bottom cushioning material 4. Therefore, in the reinforcing corrugated cardboard 7, the upper support portion 7d receives the load from the top surface of the outdoor unit 200, and the lower support portion 7e stretches the load from the top surface of the outdoor unit 200 on the upper surface of the bottom cushioning material 4. It serves as a support. As a result, the number of parts can be reduced while ensuring the withstand voltage.
　また、本実施の形態１に係る包装体１００によれば、補強段ボール７が天面緩衝材３および底面緩衝材４によって挟まれて固定されるので、室外機２００を包装する際、従来のように自立しない断面Ｌ型支柱を固定させるための構造のようなものは不要となる。そのため、それによって包装体１００で室外機２００を包装した際の室外機２００の外形寸法が大きくなるのを防ぐことができる。 Further, according to the packaging body 100 according to the first embodiment, the reinforcing corrugated cardboard 7 is sandwiched and fixed by the top cushioning material 3 and the bottom cushioning material 4, so that when the outdoor unit 200 is packaged, it is as in the conventional case. There is no need for a structure for fixing an L-shaped column having a cross section that does not stand on its own. Therefore, it is possible to prevent the external size of the outdoor unit 200 from becoming large when the outdoor unit 200 is packaged in the package 100.
　また、本実施の形態１に係る包装体１００において、補強段ボール７は、左端および右端が折り曲げられて形成された折り曲げ部７ｃを有している。 Further, in the package 100 according to the first embodiment, the reinforced corrugated cardboard 7 has a bent portion 7c formed by bending the left end and the right end.
　本実施の形態１に係る包装体１００によれば、補強段ボール７の左右の側部にそれぞれ折り曲げ部７ｃを有しているため、補強段ボール７の剛性を上げ、補強段ボール７の耐圧強度を増加させることができる。 According to the package 100 according to the first embodiment, since the reinforcing cardboard 7 has bent portions 7c on the left and right sides, the rigidity of the reinforcing cardboard 7 is increased and the pressure resistance strength of the reinforcing cardboard 7 is increased. Can be made to.

Hereinafter, the second embodiment will be described, but the description of the parts overlapping with the first embodiment will be omitted, and the same parts or the corresponding parts as those of the first embodiment will be designated by the same reference numerals.
　図１１は、本実施の形態２に係る包装体１００の要部を示す斜視図である。図１２は、本実施の形態２に係る包装体１００の要部の縦断面模式図である。 FIG. 11 is a perspective view showing a main part of the package 100 according to the second embodiment. FIG. 12 is a schematic vertical cross-sectional view of a main part of the package 100 according to the second embodiment.
　本実施の形態２に係る包装体１００では、図１１および図１２に示すように、底面緩衝材４に断面視して矩形状の固定溝部４ａが設けられている。そして、補強段ボール７の下部支持部７ｅが底面緩衝材４の固定溝部４ａに差し込まれ、差し込まれた下部支持部７ｅの折り曲げ部７ｃが底面緩衝材４の上面と接触することで、固定される。このようにすることで、圧縮荷重および輸送振動などによって生じる、天面緩衝材３および底面緩衝材４の接触面における補強段ボール７の滑り逃げ、つまり水平方向のズレを抑制することができ、補強段ボール７を強固に固定することができる。なお、補強段ボール７の下部支持部７ｅを底面緩衝材４の固定溝部４ａに差し込みやすくするため、固定溝部４ａの溝幅は折り曲げ部７ｃの左右方向の長さよりも長くなっている。そのため、下部支持部７ｅと固定溝部４ａの側壁部４ａ１との間には、隙間２２が生じている。 In the package 100 according to the second embodiment, as shown in FIGS. 11 and 12, the bottom cushioning material 4 is provided with a rectangular fixing groove 4a in a cross-sectional view. Then, the lower support portion 7e of the reinforced corrugated cardboard 7 is inserted into the fixing groove portion 4a of the bottom cushioning material 4, and the bent portion 7c of the inserted lower support portion 7e comes into contact with the upper surface of the bottom cushioning material 4 to be fixed. .. By doing so, it is possible to suppress the slip escape of the reinforcing corrugated cardboard 7 on the contact surfaces of the top surface cushioning material 3 and the bottom surface cushioning material 4, that is, the horizontal displacement caused by the compressive load and the transport vibration, and the reinforcement can be suppressed. The corrugated cardboard 7 can be firmly fixed. The groove width of the fixed groove portion 4a is longer than the length of the bent portion 7c in the left-right direction so that the lower support portion 7e of the reinforced corrugated cardboard 7 can be easily inserted into the fixed groove portion 4a of the bottom cushioning material 4. Therefore, a gap 22 is formed between the lower support portion 7e and the side wall portion 4a1 of the fixed groove portion 4a.
　以上、本実施の形態２に係る包装体１００において、底面緩衝材４には、固定溝部４ａが設けられている。そして、補強段ボール７は、下部支持部７ｅが固定溝部４ａに差し込まれ、折り曲げ部７ｃが底面緩衝材４の上面と接触することで、固定される。 As described above, in the package 100 according to the second embodiment, the bottom cushioning material 4 is provided with the fixing groove portion 4a. Then, the reinforcing corrugated cardboard 7 is fixed by the lower support portion 7e being inserted into the fixing groove portion 4a and the bent portion 7c coming into contact with the upper surface of the bottom cushioning material 4.
　本実施の形態２に係る包装体１００によれば、底面緩衝材４には、固定溝部４ａが設けられている。そして、補強段ボール７は、下部支持部７ｅが固定溝部４ａに差し込まれ、折り曲げ部７ｃが底面緩衝材４の上面と接触することで、固定される。そのため、圧縮荷重および輸送振動などによって生じる、天面緩衝材３および底面緩衝材４の接触面における補強段ボール７の滑り逃げ、つまり水平方向のズレを抑制することができ、補強段ボール７を強固に固定することができる。 According to the package 100 according to the second embodiment, the bottom cushioning material 4 is provided with a fixing groove 4a. Then, the reinforcing corrugated cardboard 7 is fixed by the lower support portion 7e being inserted into the fixing groove portion 4a and the bent portion 7c coming into contact with the upper surface of the bottom cushioning material 4. Therefore, it is possible to prevent the reinforcing corrugated cardboard 7 from slipping away on the contact surfaces of the top cushioning material 3 and the bottom cushioning material 4, that is, to be displaced in the horizontal direction, which is caused by a compressive load and transport vibration, and to strengthen the reinforcing corrugated cardboard 7. Can be fixed.
　実施の形態３．
　以下、本実施の形態３について説明するが、実施の形態１および２と重複するものについては説明を省略し、実施の形態１および２と同じ部分または相当する部分には同じ符号を付す。 Embodiment 3.
Hereinafter, the third embodiment will be described, but the description of the parts overlapping with the first and second embodiments will be omitted, and the same parts or the corresponding parts as those of the first and second embodiments will be designated by the same reference numerals.
　図１３は、本実施の形態３に係る包装体１００の要部を示す斜視図である。図１４は、本実施の形態３に係る包装体１００の要部の縦断面模式図である。 FIG. 13 is a perspective view showing a main part of the package 100 according to the third embodiment. FIG. 14 is a schematic vertical cross-sectional view of a main part of the package 100 according to the third embodiment.
　本実施の形態３に係る包装体１００では、図１３および図１４に示すように、底面緩衝材４に断面視してテーパー形状のテーパー溝部４ｂが設けられている。そして、補強段ボール７の下部支持部７ｅが底面緩衝材４のテーパー溝部４ｂに差し込まれる。このとき、テーパー溝部４ｂがテーパー形状となっているため、下部支持部７ｅは、折り曲げ部７ｃがスプリングバックして角部７ｂが断面Ｊ字状の状態で固定される。なお、下部支持部７ｅは、角部７ｂが厳密に断面Ｊ字状の状態で固定されていなくてもよく、ほぼ断面Ｊ字状の状態で固定されていればよい。また、下部支持部７ｅの折り曲げ部７ｃがスプリングバックを強くするため、折り曲げ部７ｃの折り曲げ角度７ｆは、３０°程度がよい。 In the package 100 according to the third embodiment, as shown in FIGS. 13 and 14, the bottom cushioning material 4 is provided with a tapered groove portion 4b having a tapered shape in a cross-sectional view. Then, the lower support portion 7e of the reinforced corrugated cardboard 7 is inserted into the tapered groove portion 4b of the bottom cushioning material 4. At this time, since the tapered groove portion 4b has a tapered shape, the lower support portion 7e is fixed in a state where the bent portion 7c springs back and the corner portion 7b has a J-shaped cross section. The lower support portion 7e does not have to have the corner portion 7b fixed in a strictly J-shaped cross section, and may be fixed in a substantially J-shaped cross section. Further, since the bent portion 7c of the lower support portion 7e strengthens the springback, the bending angle 7f of the bent portion 7c is preferably about 30 °.
　ここで、実施の形態２では、固定溝部４ａの溝幅は折り曲げ部７ｃの左右方向の長さよりも長くなっており、補強段ボール７の下部支持部７ｅを底面緩衝材４の固定溝部４ａに差し込んだ際に、下部支持部７ｅと固定溝部４ａの側壁部４ａ１との間に隙間２２が生じていた。一方、本実施の形態３では、テーパー溝部４ｂの一番広い溝幅でも、折り曲げ部７ｃの左右方向の長さよりも短くなっており、補強段ボール７の下部支持部７ｅを底面緩衝材４のテーパー溝部４ｂに差し込んだ際に、折り曲げ部７ｃがスプリングバックする。そのため、下部支持部７ｅとテーパー溝部４ｂの側壁部４ｂ１との間に隙間２２が生じない。その結果、折り曲げ部７ｃがスプリングバックすることによって水平方向のズレを抑制でき、補強段ボール７をより強固に固定することができる。 Here, in the second embodiment, the groove width of the fixed groove portion 4a is longer than the length of the bent portion 7c in the left-right direction, and the lower support portion 7e of the reinforced corrugated cardboard 7 is inserted into the fixed groove portion 4a of the bottom cushioning material 4. At that time, a gap 22 was formed between the lower support portion 7e and the side wall portion 4a1 of the fixed groove portion 4a. On the other hand, in the third embodiment, even the widest groove width of the tapered groove portion 4b is shorter than the length of the bent portion 7c in the left-right direction, and the lower support portion 7e of the reinforcing corrugated cardboard 7 is tapered by the bottom cushioning material 4. When inserted into the groove 4b, the bent portion 7c springs back. Therefore, no gap 22 is formed between the lower support portion 7e and the side wall portion 4b1 of the tapered groove portion 4b. As a result, the bent portion 7c springs back, so that the displacement in the horizontal direction can be suppressed, and the reinforced corrugated cardboard 7 can be fixed more firmly.
　なお、本実施の形態３では、テーパー溝部４ｂの一番広い溝幅が、折り曲げ部７ｃの左右方向の長さよりも短くなっているが、それに限定されない。テーパー溝部４ｂの一番広い溝幅が、折り曲げ部７ｃの左右方向の長さよりも長くなっていても、テーパー溝部４ｂの一番狭い溝幅が、折り曲げ部７ｃの左右方向の長さよりも短くなっていればよい。そうすることで、補強段ボール７の下部支持部７ｅを底面緩衝材４のテーパー溝部４ｂに差し込んだ際に、折り曲げ部７ｃがスプリングバックするため、下部支持部７ｅとテーパー溝部４ｂの側壁部４ｂ１との間に隙間２２が生じない。 In the third embodiment, the widest groove width of the tapered groove portion 4b is shorter than the length of the bent portion 7c in the left-right direction, but the present invention is not limited to this. Even if the widest groove width of the tapered groove portion 4b is longer than the length of the bent portion 7c in the left-right direction, the narrowest groove width of the tapered groove portion 4b is shorter than the length of the bent portion 7c in the left-right direction. I just need to be there. By doing so, when the lower support portion 7e of the reinforcing corrugated cardboard 7 is inserted into the tapered groove portion 4b of the bottom cushioning material 4, the bent portion 7c springs back, so that the lower support portion 7e and the side wall portion 4b1 of the tapered groove portion 4b No gap 22 is formed between the two.
　以上、本実施の形態３に係る包装体１００において、底面緩衝材４には、テーパー溝部４ｂが設けられている。そして、補強段ボール７は、下部支持部７ｅがテーパー溝部４ｂに差し込まれ、折り曲げ部７ｃがスプリングバックして固定される。 As described above, in the package 100 according to the third embodiment, the bottom cushioning material 4 is provided with the tapered groove portion 4b. Then, in the reinforcing corrugated cardboard 7, the lower support portion 7e is inserted into the tapered groove portion 4b, and the bent portion 7c is spring-backed and fixed.
　本実施の形態３に係る包装体１００によれば、底面緩衝材４には、テーパー溝部４ｂが設けられている。そして、補強段ボール７は、下部支持部７ｅがテーパー溝部４ｂに差し込まれ、折り曲げ部７ｃがスプリングバックして固定される。このように、補強段ボール７の下部支持部７ｅを底面緩衝材４のテーパー溝部４ｂに差し込んだ際に、折り曲げ部７ｃがスプリングバックするため、下部支持部７ｅとテーパー溝部４ｂの側壁部４ｂ１との間に隙間２２が生じない。その結果、折り曲げ部７ｃがスプリングバックすることによって水平方向のズレを抑制でき、補強段ボール７をより強固に固定することができる。 According to the package 100 according to the third embodiment, the bottom cushioning material 4 is provided with a tapered groove portion 4b. Then, in the reinforcing corrugated cardboard 7, the lower support portion 7e is inserted into the tapered groove portion 4b, and the bent portion 7c is spring-backed and fixed. In this way, when the lower support portion 7e of the reinforced corrugated cardboard 7 is inserted into the tapered groove portion 4b of the bottom cushioning material 4, the bent portion 7c springs back, so that the lower support portion 7e and the side wall portion 4b1 of the tapered groove portion 4b No gap 22 is formed between them. As a result, the bent portion 7c springs back, so that the displacement in the horizontal direction can be suppressed, and the reinforced corrugated cardboard 7 can be fixed more firmly.
　実施の形態４．
　以下、本実施の形態４について説明するが、実施の形態１～３と重複するものについては説明を省略し、実施の形態１～３と同じ部分または相当する部分には同じ符号を付す。 Embodiment 4.
Hereinafter, the fourth embodiment will be described, but the description of the parts overlapping with the first to third embodiments will be omitted, and the same parts or the corresponding parts as those of the first to third embodiments will be designated by the same reference numerals.
　図１５は、本実施の形態４に係る包装体１００の補強段ボール７の折り曲げ加工前を示す正面図である。図１６は、本実施の形態４に係る包装体１００の要部を示す斜視図である。 FIG. 15 is a front view showing the reinforced corrugated cardboard 7 of the packaging body 100 according to the fourth embodiment before bending. FIG. 16 is a perspective view showing a main part of the package 100 according to the fourth embodiment.
　本実施の形態４に係る包装体１００では、図１５に示すように、補強段ボール７を正面視して下端に複数の切り込み７ｇが形成されており、下端が折り曲げ線７ａに沿って折り曲げられることで、複数の角部７ｂおよび折り曲げ部７ｃが形成される。なお、補強段ボール７の下端は、部分毎に異なる角度に折り曲げることが可能であり、本実施の形態４では、角部７ｂが断面Ｌ字状または断面Ｊ字状となるように、折り曲げられる。 In the package 100 according to the fourth embodiment, as shown in FIG. 15, a plurality of notches 7g are formed at the lower end when the reinforcing corrugated cardboard 7 is viewed from the front, and the lower end is bent along the bending line 7a. A plurality of corner portions 7b and bent portions 7c are formed. The lower end of the reinforced corrugated cardboard 7 can be bent at different angles for each portion, and in the fourth embodiment, the corner portion 7b is bent so as to have an L-shaped cross section or a J-shaped cross section.
　また、包装体１００では、図１６に示すように、底面緩衝材４に断面視して矩形状の固定溝部４ａが設けられており、さらに、固定溝部４ａの一部に断面視してテーパー形状のテーパー溝部４ｂが設けられている。なお、上記の切り込み７ｇは、補強段ボール７の下端において、テーパー溝部４ｂの位置に合わせた位置に形成されている。 Further, in the package 100, as shown in FIG. 16, the bottom cushioning material 4 is provided with a rectangular fixing groove portion 4a in cross section, and further, a part of the fixing groove portion 4a is tapered in cross section. The tapered groove portion 4b of the above is provided. The notch 7g is formed at the lower end of the reinforced corrugated cardboard 7 at a position aligned with the position of the tapered groove portion 4b.
　また、補強段ボール７の下部支持部７ｅは、断面Ｌ字状の角部７ｂと折り曲げ部７ｃとで構成されたＬ字状部７ｈと、断面Ｊ字状の角部７ｂと折り曲げ部７ｃとで構成されたＪ字状部７ｉとを有している。そして、補強段ボール７の下部支持部７ｅのＬ字状部７ｈが底面緩衝材４の固定溝部４ａに差し込まれ、さらにＪ字状部７ｉがテーパー溝部４ｂに差し込まれる。このとき、Ｌ字状部７ｈの折り曲げ部７ｃおよび角部７ｂの一部が底面緩衝材４の上面と接触して固定される。そのため、圧縮荷重および輸送振動などによって生じる、天面緩衝材３および底面緩衝材４の接触面における補強段ボール７の滑り逃げ、つまり水平方向のズレを抑制することができ、補強段ボール７を強固に固定することができる。また、テーパー溝部４ｂがテーパー形状となっているため、Ｌ字状部７ｈの折り曲げ部７ｃがスプリングバックして角部７ｂが断面Ｊ字状の状態で固定される。そのため、折り曲げ部７ｃがスプリングバックすることによって水平方向のズレを抑制でき、補強段ボール７をより強固に固定することができる。 Further, the lower support portion 7e of the corrugated cardboard 7 is composed of an L-shaped portion 7h composed of a corner portion 7b having an L-shaped cross section and a bent portion 7c, and a corner portion 7b having a J-shaped cross section and a bent portion 7c. It has a J-shaped portion 7i configured. Then, the L-shaped portion 7h of the lower support portion 7e of the reinforced corrugated cardboard 7 is inserted into the fixing groove portion 4a of the bottom cushioning material 4, and the J-shaped portion 7i is further inserted into the tapered groove portion 4b. At this time, a part of the bent portion 7c and the corner portion 7b of the L-shaped portion 7h comes into contact with the upper surface of the bottom surface cushioning material 4 and is fixed. Therefore, it is possible to prevent the reinforcing corrugated cardboard 7 from slipping away on the contact surfaces of the top cushioning material 3 and the bottom cushioning material 4, that is, to be displaced in the horizontal direction, which is caused by a compressive load and transport vibration, and to strengthen the reinforcing corrugated cardboard 7. Can be fixed. Further, since the tapered groove portion 4b has a tapered shape, the bent portion 7c of the L-shaped portion 7h springs back and the corner portion 7b is fixed in a state of a J-shaped cross section. Therefore, the bent portion 7c springs back, so that the displacement in the horizontal direction can be suppressed, and the reinforced corrugated cardboard 7 can be fixed more firmly.
　なお、Ｌ字状部７ｈは、角部７ｂが厳密に断面Ｌ字状でなくてもよく、ほぼ断面Ｌ字状であればよい。また、Ｊ字状部７ｉは、角部７ｂが厳密に断面Ｊ字状の状態で固定されていなくてもよく、ほぼ断面Ｊ字状の状態で固定されていればよい。また、Ｌ字状部７ｈの折り曲げ部７ｃがスプリングバックを強くするため、折り曲げ部７ｃの折り曲げ角度７ｆは、３０°程度がよい。 The corner portion 7b of the L-shaped portion 7h does not have to be strictly L-shaped in cross section, and may be substantially L-shaped in cross section. Further, in the J-shaped portion 7i, the corner portion 7b does not have to be fixed in a strictly J-shaped cross section, and may be fixed in a substantially J-shaped cross section. Further, since the bent portion 7c of the L-shaped portion 7h strengthens the springback, the bending angle 7f of the bent portion 7c is preferably about 30 °.
　ここで、補強段ボール７の下部支持部７ｅのＬ字状部７ｈとＪ字状部７ｉとを比較すると、Ｌ字状部７ｈの方が底面緩衝材４の上面と接触する受け面積が大きく、Ｌ字状部７ｈの方が、耐圧強度が強い。 Here, comparing the L-shaped portion 7h of the lower support portion 7e of the reinforced corrugated cardboard 7 with the J-shaped portion 7i, the L-shaped portion 7h has a larger receiving area in contact with the upper surface of the bottom cushioning material 4. The L-shaped portion 7h has stronger pressure resistance.
　また、補強段ボール７の下部支持部７ｅのＪ字状部７ｉを底面緩衝材４のテーパー溝部４ｂに差し込んだ際に、折り曲げ部７ｃがスプリングバックする。そのため、下部支持部７ｅのＪ字状部７ｉとテーパー溝部４ｂの側壁部４ｂ１との間に隙間２２が生じず、水平方向のズレを抑制できる。 Further, when the J-shaped portion 7i of the lower support portion 7e of the reinforced corrugated cardboard 7 is inserted into the tapered groove portion 4b of the bottom cushioning material 4, the bent portion 7c springs back. Therefore, a gap 22 does not occur between the J-shaped portion 7i of the lower support portion 7e and the side wall portion 4b1 of the tapered groove portion 4b, and the deviation in the horizontal direction can be suppressed.
　その結果、補強段ボール７の水平方向のズレを抑制しつつ、耐圧強度をさらに増加させることができる。 As a result, the pressure resistance strength can be further increased while suppressing the horizontal displacement of the reinforced corrugated cardboard 7.
　以上、本実施の形態４に係る包装体１００において、底面緩衝材４には、固定溝部４ａと固定溝部４ａの一部に形成されたテーパー溝部４ｂとが設けられている。また、下部支持部７ｅは、折り曲げ部７ｃと断面Ｌ字状の角部７ｂとで構成されたＬ字状部７ｈと、折り曲げ部７ｃと断面Ｊ字状の角部７ｂとで構成されたＪ字状部７ｉとを有している。そして、補強段ボール７は、下部支持部７ｅのＬ字状部７ｈが固定溝部４ａに差し込まれ、Ｌ字状部７ｈの折り曲げ部７ｃおよび角部７ｂが底面緩衝材４の上面と接触するとともに、Ｊ字状部７ｉがテーパー溝部４ｂに差し込まれ、Ｊ字状部７ｉの折り曲げ部７ｃがスプリングバックして固定される。 As described above, in the package 100 according to the fourth embodiment, the bottom cushioning material 4 is provided with a fixed groove portion 4a and a tapered groove portion 4b formed in a part of the fixed groove portion 4a. Further, the lower support portion 7e is a J composed of an L-shaped portion 7h composed of a bent portion 7c and an L-shaped corner portion 7b, and a bent portion 7c and a corner portion 7b having a J-shaped cross section. It has a character-shaped portion 7i. Then, in the reinforcing corrugated cardboard 7, the L-shaped portion 7h of the lower support portion 7e is inserted into the fixing groove portion 4a, and the bent portion 7c and the corner portion 7b of the L-shaped portion 7h come into contact with the upper surface of the bottom cushioning material 4. The J-shaped portion 7i is inserted into the tapered groove portion 4b, and the bent portion 7c of the J-shaped portion 7i is springbacked and fixed.
　本実施の形態４に係る包装体１００によれば、底面緩衝材４には、固定溝部４ａと固定溝部４ａの一部に形成されたテーパー溝部４ｂとが設けられている。また、下部支持部７ｅは、折り曲げ部７ｃと断面Ｌ字状の角部７ｂとで構成されたＬ字状部７ｈと、折り曲げ部７ｃと断面Ｊ字状の角部７ｂとで構成されたＪ字状部７ｉとを有している。そして、補強段ボール７は、下部支持部７ｅのＬ字状部７ｈが固定溝部４ａに差し込まれ、Ｌ字状部７ｈの折り曲げ部７ｃおよび角部７ｂが底面緩衝材４の上面と接触して固定される。さらに、補強段ボール７は、Ｊ字状部７ｉがテーパー溝部４ｂに差し込まれ、Ｊ字状部７ｉの折り曲げ部７ｃがスプリングバックして固定される。そのため、補強段ボール７の水平方向のズレを抑制しつつ、耐圧強度をさらに増加させることができる。 According to the package 100 according to the fourth embodiment, the bottom cushioning material 4 is provided with a fixed groove portion 4a and a tapered groove portion 4b formed in a part of the fixed groove portion 4a. Further, the lower support portion 7e is a J composed of an L-shaped portion 7h composed of a bent portion 7c and an L-shaped corner portion 7b, and a bent portion 7c and a corner portion 7b having a J-shaped cross section. It has a character-shaped portion 7i. Then, in the reinforcing corrugated cardboard 7, the L-shaped portion 7h of the lower support portion 7e is inserted into the fixing groove portion 4a, and the bent portion 7c and the corner portion 7b of the L-shaped portion 7h come into contact with the upper surface of the bottom cushioning material 4 and fixed. Will be done. Further, in the reinforced corrugated cardboard 7, the J-shaped portion 7i is inserted into the tapered groove portion 4b, and the bent portion 7c of the J-shaped portion 7i is spring-backed and fixed. Therefore, the pressure resistance strength can be further increased while suppressing the displacement of the reinforced corrugated cardboard 7 in the horizontal direction.
