　しかしながら、筒状梱包材を構成する段ボールは、２枚の平らな紙の間に波型の紙が挟まった構造となっており、内包する室内機を保護するため、耐衝撃性が得られるよう一定の厚みを有している。よって、段ボールの端部同士をステープルで留めるとき、ステープルにより段ボールが押しつぶされて陥没し、表層の平らな紙等が破けるため、意匠性が損なわれ、外力に対する脆弱性が増加するという課題がある。 However, the corrugated cardboard constituting the cylindrical packing material has a structure in which corrugated paper is sandwiched between two flat papers, and in order to protect the contained indoor unit, impact resistance is obtained. It has a certain thickness. Therefore, when the ends of the corrugated cardboard are stapled together, the staples crush the corrugated cardboard and collapse, and the flat paper or the like on the surface layer is broken. is there.
　本発明は、上記のような課題を解決するためになされたものであり、筒状梱包材を構成する段ボールの端部同士をステープルで固定しても、意匠性を損なうことなく、外力への耐性を維持する梱包ユニット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 problems, and even if the ends of the corrugated cardboard constituting the cylindrical packing material are fixed with staples, without impairing the design property, it is possible to prevent external force. An object is to provide a packaging unit that maintains resistance.
　本発明に係る梱包ユニットは、直方体形状である空気調和機の室内機を梱包する梱包ユニットであって、室内機における長手方向の両端部に装着される一対の緩衝梱包材と、室内機の長手方向に沿った周囲を囲み、一対の緩衝梱包材に跨がって配置される筒状梱包材と、を有し、筒状梱包材は、板状の段ボールが筒状に折り曲げられ、互いに重ねられた一端の対向部と他端の固定部材とが複数のステープルで留められており、対向部及び固定部材は、基準厚さの半分以下の厚みとなっている。 The packing unit according to the present invention is a packing unit for packing an indoor unit of an air conditioner having a rectangular parallelepiped shape, and a pair of cushioning packing materials attached to both longitudinal ends of the indoor unit, A tubular packing material surrounding the perimeter along the direction and disposed over a pair of cushioning packing materials, wherein the tubular packing material is obtained by bending a plate-shaped cardboard into a tubular shape and overlapping each other. The opposing portion at one end and the fixing member at the other end are fixed with a plurality of staples, and the opposing portion and the fixing member have a thickness of half or less of the reference thickness.
　本発明によれば、対向部及び固定部材の厚みが基準厚さの半分以下となっていることから、対向部と固定部材とをステープルで固定しても、対向部の表層の平らな紙等が破けないため、意匠性を損なうことなく、外力への耐性を維持することができる。 According to the present invention, since the thickness of the facing portion and the fixing member is equal to or less than half of the reference thickness, even if the facing portion and the fixing member are fixed with staples, the surface layer of the facing portion can be flat paper or the like. Since it does not break, it is possible to maintain resistance to external force without impairing the design.

In particular, the positive direction of the x-axis is defined as the forward direction, and the positive direction of the z-axis is defined as the upward direction. The same applies to the following drawings. The y-axis direction corresponds to the longitudinal direction of the indoor unit 300. Hereinafter, the longitudinal direction of the indoor unit 300 is also referred to as “longitudinal direction”.
　図１に示すように、梱包ユニット５０は、室内機３００の長手方向の両端部に装着される一対の緩衝梱包材として、第１緩衝梱包材２１と第２緩衝梱包材２２とを有している。第１緩衝梱包材２１及び第２緩衝梱包材２２は、発泡スチロールなどの緩衝材を材料として成形されたものである。また、梱包ユニット５０は、室内機３００の長手方向に沿った周囲を囲み、一対の緩衝梱包材、すなわち第１緩衝梱包材２１と第２緩衝梱包材２２とに跨がって配置される筒状梱包材１０を有している。加えて、梱包ユニット５０は、２本のバンド４０を有している。バンド４０は、第１緩衝梱包材２１と筒状梱包材１０と第２緩衝梱包材２２とを結束するものである。 As shown in FIG. 1, the packing unit 50 has a first buffer packing material 21 and a second buffer packing material 22 as a pair of buffer packing materials attached to both ends in the longitudinal direction of the indoor unit 300. I have. The first cushioning packaging material 21 and the second cushioning packaging material 22 are formed using a cushioning material such as styrene foam. Further, the packing unit 50 surrounds the circumference along the longitudinal direction of the indoor unit 300, and is a tube arranged over a pair of buffer packing materials, that is, the first buffer packing material 21 and the second buffer packing material 22. It has a shape-like packing material 10. In addition, the packing unit 50 has two bands 40. The band 40 binds the first cushioning packaging material 21, the tubular packaging material 10, and the second cushioning packaging material 22.
　図２は、図１の筒状梱包材を構成する段ボールの展開図である。図２に示すように、筒状梱包材１０は、室内機３００の長手方向に沿った４つの側面のそれぞれに対向して配置されるシート部材を有している。以降では、図２に示すように、複数のシート部材を、それぞれ、第１シート部材１１、第２シート部材１２、第３シート部材１３、第４シート部材１４という。第２シート部材１２は第１シート部材１１に隣接しており、第３シート部材１３は第２シート部材１２に隣接しており、第４シート部材１４は第３シート部材１３に隣接している。 FIG. 2 is a development view of the cardboard constituting the cylindrical packing material of FIG. As shown in FIG. 2, the tubular packing material 10 has sheet members disposed to face each of four side surfaces along the longitudinal direction of the indoor unit 300. Hereinafter, as shown in FIG. 2, the plurality of sheet members are referred to as a first sheet member 11, a second sheet member 12, a third sheet member 13, and a fourth sheet member 14, respectively. The second sheet member 12 is adjacent to the first sheet member 11, the third sheet member 13 is adjacent to the second sheet member 12, and the fourth sheet member 14 is adjacent to the third sheet member 13. .
　また、筒状梱包材１０は、第４シート部材１４に接続された固定部材１５を有している。固定部材１５は、第４シート部材１４の第３シート部材１３とは反対側の端部に接続されている。すなわち、第１シート部材１１と第２シート部材１２と第３シート部材１３と第４シート部材１４と固定部材１５とは、一体的な板状の段ボールを構成している。 筒 Moreover, the cylindrical packing material 10 has a fixing member 15 connected to the fourth sheet member 14. The fixing member 15 is connected to the end of the fourth sheet member 14 opposite to the third sheet member 13. That is, the first sheet member 11, the second sheet member 12, the third sheet member 13, the fourth sheet member 14, and the fixing member 15 form an integrated plate-shaped cardboard.
　固定部材１５は、筒状梱包材１０によって室内機３００の長手方向に沿った周囲を囲んだ状態で、第１シート部材１１の室内機３００側の面に対向して配置される。第１シート部材１１は、固定部材１５が対向して配置される対向部１１ａを有している。以降では、固定部材１５と対向部１１ａとを合わせて接合部ともいう。 The fixing member 15 is arranged to face the surface of the first sheet member 11 on the indoor unit 300 side in a state of surrounding the circumference along the longitudinal direction of the indoor unit 300 by the cylindrical packing material 10. The first sheet member 11 has an opposing portion 11a on which the fixing member 15 is arranged to oppose. Hereinafter, the fixing member 15 and the facing portion 11a are collectively referred to as a joint.
　対向部１１ａ及び固定部材１５の厚みは、他のシート部材の厚みよりも薄くなっている。ここで、他のシート部材の厚みとは、第２シート部材１２、第３シート部材１３、及び第４シート部材１４の厚みのことであり、以降では「基準厚さＴＯ」ともいう。なお、本実施の形態１では、第１シート部材１１の対向部１１ａ以外の部分の厚みも基準厚さＴＯとなっている。 The thickness of the facing portion 11a and the fixing member 15 is smaller than the thickness of the other sheet members. Here, the thickness of the other sheet member refers to the thickness of the second sheet member 12, the third sheet member 13, and the fourth sheet member 14, and is hereinafter also referred to as “reference thickness T O ”. In the first embodiment, the thickness of the portion other than the opposing portion 11a of the first sheet member 11 also has a reference thickness T O.
　ここで、筒状梱包材１０を構成する段ボールは、２枚の平らな紙である一対のライナの間に、波型の紙である中芯が挟まった構造となっている。そして、第１シート部材１１と第２シート部材１２と第３シート部材１３と第４シート部材１４と固定部材１５とは、中芯が波打つ方向である流れ方向に沿って配置されている。なお、流れ方向に対直な方向は、流れ方向よりも段ボールが折れにくい紙巾方向（目方向）である。 Here, the corrugated cardboard constituting the tubular packing material 10 has a structure in which a corrugated paper core is sandwiched between a pair of liners made of two flat papers. And the 1st sheet member 11, the 2nd sheet member 12, the 3rd sheet member 13, the 4th sheet member 14, and the fixing member 15 are arrange | positioned along the flow direction which is the direction in which the center core is waving. The direction perpendicular to the flow direction is the paper width direction (mesh direction) where the corrugated board is less likely to break than the flow direction.
　図３は、図２の段ボールのＡ－Ａ線に沿った概略断面図である。本実施の形態１の筒状梱包材１０は、対向部１１ａの厚みＴ１が、他のシート部材の厚みの半分以下となっており、固定部材１５の厚みＴ５も、他のシート部材の厚みの半分以下となっている。対向部１１ａの厚みＴ１及び固定部材１５の厚みＴ５は、耐衝撃性を確保するため、中芯がつぶれて平らにならない程度の厚みを下限にするとよい。 FIG. 3 is a schematic cross-sectional view of the cardboard of FIG. 2 taken along line AA. Tubular packaging material 10 of the first embodiment, the thickness T 1 of the opposing portion 11a has become less than half of the thickness of the other sheet member, even the thickness T 5 of the fixed member 15, the other sheet member It is less than half the thickness. The thickness T 5 of thickness T 1 and the fixed member 15 of the opposing portion 11a in order to secure the impact resistance, the thickness of the extent to which the central core does not become flat collapses may be the lower limit.
　筒状梱包材１０は、図３（ａ）のように、厚みが均一な段ボールの対向部１１ａ及び固定部材１５に対応する部分を、図３（ｂ）のように、プレス加工によって押しつぶして形成されている。より具体的に、対向部１１ａは、第１シート部材１１Ｏの対向部１１ａとなる部分を、室内機３００側に向けられる面側から押しつぶすことによって形成される。同様に、固定部材１５は、固定シート部材１５Ｏを、室内機３００に向けられる面側から押しつぶすことによって形成される。すなわち、基準厚さＴＯは、対向部１１ａ及び固定部材１５の元の厚さに相当する。 As shown in FIG. 3A, the cylindrical packing material 10 is formed by crushing a portion corresponding to the facing portion 11a and the fixing member 15 of the cardboard having a uniform thickness by press working as shown in FIG. 3B. Have been. More specifically, the opposing portion 11a is formed by crushing a portion to be the first sheet member 11 O of the opposing portion 11a, from the side which is directed to the indoor unit 300 side. Similarly, the fixing member 15 is formed by crushing fixing sheet member 15 O, from the side which is directed to the indoor unit 300. That is, the reference thickness T O corresponds to the original thickness of the opposing portion 11a and the fixing member 15.
　もっとも、対向部１１ａ及び固定部材１５は、筒状梱包材１０を構成する段ボールの型抜きと同時に、プレス加工によって形成されてもよい。また、対向部１１ａの流れ方向に沿った幅Ｗ１と、固定部材１５の流れ方向に沿った幅Ｗ５とは、等しくなるようにするとよい。 However, the facing portion 11a and the fixing member 15 may be formed by pressing at the same time when the corrugated cardboard constituting the cylindrical packaging material 10 is die-cut. Further, the width W 1 along the flow direction of the opposing portion 11a, the width W 5 along the flow direction of the fixing member 15, it is preferable to be equal.
　図４は、図２の段ボールを筒状に組み立てて筒状梱包材を構成した状態を示す斜視図である。図５は、図４の筒状梱包材を上側からみた平面図である。図４及び図５に示すように、筒状梱包材１０において、対向部１１ａと固定部材１５とは、室内機３００の長手方向に沿って複数のステープル３０で留められている。すなわち、筒状梱包材１０は、板状の段ボールが筒状に折り曲げられ、互いに重ねられた一端の対向部１１ａと他端の固定部材１５とが複数のステープル３０で留められている。 FIG. 4 is a perspective view showing a state in which the cardboard of FIG. 2 is assembled into a cylindrical shape to form a cylindrical packing material. FIG. 5 is a plan view of the cylindrical packing material of FIG. 4 as viewed from above. As shown in FIGS. 4 and 5, in the cylindrical packing material 10, the facing portion 11 a and the fixing member 15 are fastened by a plurality of staples 30 along the longitudinal direction of the indoor unit 300. That is, in the tubular packing material 10, a plate-like corrugated cardboard is bent into a tubular shape, and the facing portion 11 a at one end and the fixing member 15 at the other end, which are overlapped with each other, are fastened by a plurality of staples 30.
　ここで、複数のステープル３０は、図５に示すように、長手方向に対して傾斜角θだけ傾いた状態で留められている。傾斜角θは、０°よりも大きく９０°よりも小さい角度（０°＜θ＜９０°）に設定される。よって、長手方向に平行な状態で各ステープル３０を留める場合よりも、多くのステープル３０を用いて、対向部１１ａと固定部材１５とを留めることができる。 Here, as shown in FIG. 5, the plurality of staples 30 are retained in a state of being inclined by the inclination angle θ with respect to the longitudinal direction. Is set to an angle greater than 0 ° and smaller than 90 ° (0 ° <θ <90 °). Therefore, the opposing portion 11a and the fixing member 15 can be fastened using more staples 30 than when the staples 30 are fastened in a state parallel to the longitudinal direction.
　ところで、室内機３００を梱包する際、あるいは梱包した状態において、固定部材１５にはｘ軸負方向に力が加わり、対向部１１ａにはｘ軸正方向に力が加わる。よって、各ステープル３０を長手方向に垂直に留めた場合（図２０参照）は、各ステープル３０が段ボールの流れ方向に平行となるため、段ボールが破れやすくなり、固定強度が低下する。また、各ステープル３０を長手方向に平行に留めた場合、各ステープル３０が刺さる点が段ボールの目方向と平行に並び、狭い範囲に力が集中するため、固定強度が低下する。 When the indoor unit 300 is packed or packed, a force is applied to the fixing member 15 in the negative x-axis direction, and a force is applied to the facing portion 11a in the positive x-axis direction. Therefore, when each staple 30 is kept perpendicular to the longitudinal direction (see FIG. 20), each staple 30 is parallel to the flow direction of the corrugated cardboard, so that the corrugated cardboard is easily broken and the fixing strength is reduced. Further, when the staples 30 are fixed in parallel in the longitudinal direction, the points where the staples 30 are pierced are arranged in parallel with the eye direction of the corrugated cardboard, and the force is concentrated in a narrow range, so that the fixing strength decreases.
　この点、本実施の形態１における複数のステープル３０は、対向部１１ａと固定部材１５とを連結した状態で、長手方向に対し傾斜角θだけ傾いている。そのため、各ステープル３０が、それぞれ、流れ方向の位置が異なる２点で対向部１１ａと固定部材１５とを固定することになる。よって、各ステープル３０を長手方向に平行又は垂直に留める場合よりも、対向部１１ａと固定部材１５との固定強度を高めることができる。なお、傾斜角θは、ステープル３０の数及び固定強度の観点から４５度程度が好ましい。 In this regard, the plurality of staples 30 in the first embodiment are inclined by an inclination angle θ with respect to the longitudinal direction in a state where the opposing portion 11a and the fixing member 15 are connected. Therefore, each staple 30 fixes the opposing portion 11a and the fixing member 15 at two points at different positions in the flow direction. Therefore, the fixing strength between the opposing portion 11a and the fixing member 15 can be increased as compared with the case where each staple 30 is kept parallel or perpendicular to the longitudinal direction. The inclination angle θ is preferably about 45 degrees from the viewpoint of the number of the staples 30 and the fixing strength.
　図６は、図５のＢ－Ｂ線に沿った概略断面図である。ここで、図６では、各構成部材を明確に区別するため、各構成部材間に隙間を記載しているが、実際には、ステープル３０によって留められた対向部１１ａと固定部材１５とは、互いに接触した状態となっている。 FIG. 6 is a schematic cross-sectional view along the line BB of FIG. Here, in FIG. 6, in order to clearly distinguish each of the constituent members, a gap is described between each of the constituent members. However, in actuality, the facing portion 11 a fixed by the staple 30 and the fixing member 15 are They are in contact with each other.
　上述したように、対向部１１ａの厚みＴ１と、固定部材１５の厚みＴ５とは、基準厚さＴＯの半分以下となっている（Ｔ１≦ＴＯ／２、かつＴ５≦ＴＯ／２）。したがって、図６に例示するように、対向部１１ａの厚みＴ１と固定部材１５の厚みＴ５とを足した厚さは、基準厚さＴＯ以下となる（Ｔ１＋Ｔ５≦ＴＯ）。したがって、対向部１１ａと固定部材１５とをステープル３０で固定しても、対向部１１ａ及び固定部材１５の厚みが減っていることから、対向部１１ａの表層のライナ等が破けないため、意匠性を損なうことなく、外力への耐性を維持することができる。 As described above, the thickness T 1 of the opposing portion 11a, the thickness T 5 of the fixed member 15 is equal to or less than half the reference thickness T O (T 1 ≦ T O / 2, and T 5 ≦ T O / 2). Therefore, as illustrated in FIG. 6, thickness plus the thickness T 5 of thickness T 1 and the fixing member 15 of the facing portion 11a, becomes equal to or less than the reference thickness T O (T 1 + T 5 ≦ T O) . Therefore, even when the opposing portion 11a and the fixing member 15 are fixed with the staple 30, the thickness of the opposing portion 11a and the fixing member 15 is reduced, so that the liner or the like on the surface layer of the opposing portion 11a is not broken. The resistance to external force can be maintained without impairing.
　図７は、図１の第１緩衝梱包材を、角度を変えて例示した説明図である。図８は、図１の第２緩衝梱包材を、角度を変えて例示した説明図である。本実施の形態１の筒状梱包材では、対向部１１ａの厚みＴ１と固定部材１５の厚みＴ５とを足した厚さが基準厚さＴＯ以下となっているため、一対の緩衝梱包材の固定部材１５に対向する部分に切り欠きを設ける必要がない。 FIG. 7 is an explanatory view illustrating the first cushioning packaging material of FIG. 1 at different angles. FIG. 8 is an explanatory view illustrating the second cushioning packing material of FIG. 1 by changing the angle. The tubular packing material of the first embodiment, since the thickness plus the thickness T 5 of thickness T 1 and the fixing member 15 of the opposing portion 11a is less than or equal to the reference thickness T O, a pair of cushioning packaging There is no need to provide a notch in the portion of the material facing the fixing member 15.
　よって、図７に示すように、第１緩衝梱包材２１は、固定部材１５に対向する面である対向面２１ａが平坦に形成されている。対向面２１ａは、第１シート部材１１にも対向している。また、図８に示すように、第２緩衝梱包材２２は、固定部材１５に対向する面である対向面２２ａが平坦に形成されている。対向面２２ａは、第１シート部材１１にも対向している。ここでの平坦とは、対向面２１ａ又は対向面２２ａが、固定部材１５に対向する部分から他の部分に亘って全体的に平坦になっていることを意味し、例えば図８のように、部分的に溝状の凹部２２ｖが形成されていてもよい。 Therefore, as shown in FIG. 7, in the first buffer packaging material 21, the opposing surface 21 a that is the surface opposing the fixing member 15 is formed flat. The facing surface 21a also faces the first sheet member 11. As shown in FIG. 8, in the second cushioning packaging material 22, an opposing surface 22 a which is a surface opposing the fixing member 15 is formed flat. The facing surface 22a also faces the first sheet member 11. Flat here means that the opposing surface 21a or the opposing surface 22a is entirely flat from a portion facing the fixing member 15 to another portion, for example, as shown in FIG. A partially groove-shaped concave portion 22v may be formed.
　筒状梱包材１０は、対向部１１ａの厚みＴ１と固定部材１５の厚みＴ５とを足した厚さが基準厚さＴＯと等しくなるように構成すれば、第１シート部材１１及び固定部材１５と、対向面２１ａ及び対向面２２ａとの間の隙間をなくすことができる。よって、衝撃吸収力が増加するため、被梱包物である室内機３００をより確実に保護することができる。 Tubular packaging material 10, if configured to thickness plus the thickness T 5 of thickness T 1 and the fixing member 15 of the facing portion 11a becomes equal to the reference thickness T O, the first sheet member 11 and the fixed A gap between the member 15 and the opposing surfaces 21a and 22a can be eliminated. Therefore, the shock absorbing power increases, so that the indoor unit 300, which is a packaged object, can be more reliably protected.
　図９は、図１の梱包ユニットによって空気調和機の室内機を梱包した状態の一例を示す斜視図である。図１０は、図１の梱包ユニットによって空気調和機の室内機を梱包した状態の他の例を示す斜視図である。図９及び図１０に示すように、室内機３００は、筒状に形成された筒状梱包材１０の内部に挿入されると共に、第１緩衝梱包材２１と第２緩衝梱包材２２とにより長手方向の両端部が覆われる。そして、室内機３００は、自身を覆う第１緩衝梱包材２１、筒状梱包材１０、及び第２緩衝梱包材２２が、紐状のバンド４０で巻かれることにより、梱包される。 FIG. 9 is a perspective view showing an example of a state where the indoor unit of the air conditioner is packed by the packing unit of FIG. FIG. 10 is a perspective view illustrating another example of a state where the indoor unit of the air conditioner is packed by the packing unit of FIG. 1. As shown in FIGS. 9 and 10, the indoor unit 300 is inserted into the cylindrical packaging material 10 formed in a tubular shape, and is elongated by the first buffer packaging material 21 and the second buffer packaging material 22. Both ends in the direction are covered. Then, the indoor unit 300 is packed by winding the first buffer packing material 21, the tubular packing material 10, and the second buffer packing material 22 that cover the indoor unit 300 with the cord-shaped band 40.
　以上のように、本実施の形態１の梱包ユニット５０は、対向部１１ａの厚みＴ１と固定部材１５の厚みＴ５とが、基準厚さＴＯの半分以下となっている。よって、対向部１１ａと固定部材１５とをステープル３０で固定しても、対向部１１ａの表層のライナ等が破けないため、意匠性を損なうことなく、外力への耐性を維持することができる。 As described above, the packaging unit 50 of the first embodiment, the thickness T 1 of the opposing portion 11a and the thickness T 5 of the fixed member 15, is equal to or less than half the reference thickness T O. Therefore, even if the opposing portion 11a and the fixing member 15 are fixed with the staple 30, the liner or the like of the surface layer of the opposing portion 11a is not broken, so that it is possible to maintain the resistance to external force without impairing the design.
　また、筒状梱包材１０を構成する段ボールは、対向部１１ａ及び固定部材１５の厚さのみが基準厚さＴＯの半分以下となっており、他の部分の厚さは基準厚さＴＯのままで維持されている。つまり、筒状梱包材１０は、対向部１１ａ及び固定部材１５以外の部分が押しつぶされていない。そして、対向部１１ａと固定部材１５とが重なった接合部の厚さは、基準厚さＴＯ以下であるが、接合部には、段ボール２枚分のライナ及び中芯が存在するため、１枚の段ボールよりも耐衝撃性が高い。すなわち、筒状梱包材１０によれば、対向部１１ａ及び固定部材１５にプレス加工を加えない場合と同程度の強度を維持することができる。 In the corrugated cardboard constituting the cylindrical packing material 10, only the thickness of the facing portion 11a and the fixing member 15 is less than half of the reference thickness T O , and the thickness of the other portions is the reference thickness T O. It is maintained as it is. That is, portions of the tubular packing material 10 other than the facing portion 11a and the fixing member 15 are not crushed. Since the thickness of the joint portion overlapping the opposing portion 11a and the fixing member 15 is the reference is the thickness T O below, the junction of the liner and the corrugated medium of the two sheets cardboard is present, 1 Higher impact resistance than single piece of cardboard. That is, according to the cylindrical packing material 10, it is possible to maintain the same strength as the case where the pressing process is not applied to the facing portion 11a and the fixing member 15.
　さらに、第１緩衝梱包材２１及び第２緩衝梱包材２２は、固定部材１５に対向する面が平坦に形成されている。よって、段ボールよりも強度の大きい材料で形成される第１緩衝梱包材２１及び第２緩衝梱包材２２の体積を増やすことができるため、梱包ユニット５０の全体としての耐衝撃性を高めることができる。 Furthermore, the surfaces of the first buffer packing material 21 and the second buffer packing material 22 facing the fixing member 15 are formed flat. Therefore, since the volume of the first cushioning packaging material 21 and the second cushioning packaging material 22 formed of a material having higher strength than cardboard can be increased, the shock resistance of the entire packaging unit 50 can be enhanced. .

　図１７は、図１６の状態においてステープルの傾斜角に沿って切断した場合の概略断面図である。図１７では、図１６の梱包ユニット１５０について、第１緩衝梱包材１２１を通るように、ステープル３０の傾斜角に沿って図６と同様に切断した断面を概略的に示している。ここで、図１７では、各構成部材を明確に区別するため、各構成部材間に隙間を記載しているが、実際には、ステープル３０によって留められた対向部１１ａと固定部材１５とは、互いに接触した状態となっている。また、段上面１２１ｍは第１シート部材１１０に接触し、段下面１２１ｎは固定部材１５に接触している。 FIG. 17 is a schematic cross-sectional view of the staple cut along the inclination angle in the state of FIG. FIG. 17 schematically shows a cross section of the packing unit 150 of FIG. 16 cut along the inclination angle of the staple 30 similarly to FIG. 6 so as to pass through the first cushioning packing material 121. Here, in FIG. 17, in order to clearly distinguish each of the constituent members, a gap is described between each of the constituent members. However, in actuality, the facing portion 11 a fixed by the staple 30 and the fixing member 15 are: They are in contact with each other. The step upper surface 121m is in contact with the first sheet member 110, and the step lower surface 121n is in contact with the fixing member 15.
　図１７に示すように、段下面１２１ｎは、固定部材１５に対向するよう配置される。また、段上面１２１ｍは、第１シート部材１１０における固定部材１５と重なっていない部分に対向するよう配置される。図示は省略するが、第２緩衝梱包材１２２も、第１緩衝梱包材１２１と同様に配置される。すなわち、段下面１２２ｎは、固定部材１５に対向するよう配置される。また、段上面１２１ｍは、第１シート部材１１０における固定部材１５と重なっていない部分に対向するよう配置される。つまり、切り欠き部１２１ｋ及び切り欠き部１２２ｋは、固定部材１５に対向する部分に形成されている。 段 As shown in FIG. 17, the step lower surface 121n is arranged to face the fixing member 15. In addition, the step upper surface 121m is arranged to face a portion of the first sheet member 110 that does not overlap with the fixing member 15. Although not shown, the second buffer packing material 122 is also arranged in the same manner as the first buffer packing material 121. That is, the step lower surface 122n is arranged to face the fixing member 15. In addition, the step upper surface 121m is arranged to face a portion of the first sheet member 110 that does not overlap with the fixing member 15. That is, the notch 121k and the notch 122k are formed in a portion facing the fixing member 15.
　第１緩衝梱包材１２１は、切り欠き部１２１ｋの高さ、すなわち段壁部１２１ｗの高さΔＴが、固定部材１５の厚みＴ５と等しくなるように形成するとよい。同様に、第２緩衝梱包材１２２は、切り欠き部１２２ｋの高さ、すなわち段壁部１２２ｗの高さΔＴが、固定部材１５の厚みＴ５と等しくなるように形成するとよい。このようにすれば、第１シート部材１１０と、段上面１２１ｍ及び段上面１２２ｍとの間の隙間をなくすことができ、かつ、固定部材１５と、段下面１２１ｎ及び段下面１２２ｎとの隙間をなくすことができる。よって、衝撃吸収力が増加するため、被梱包物である室内機３００をより確実に保護することができる。 First buffer packing material 121, the height of the notch 121k, i.e. height ΔT of step wall portion 121w is preferably formed to be equal to the thickness T 5 of the fixed member 15. Similarly, the second cushioning packing material 122, the height of the notch 122k, i.e. height ΔT of step wall portion 122w is preferably formed to be equal to the thickness T 5 of the fixed member 15.

Therefore, the shock absorbing power increases, so that the indoor unit 300, which is a packaged object, can be more reliably protected.
　以上のように、本実施の形態２の梱包ユニット１５０は、対向部１１ａを含む第１シート部材１１０の厚みＴ１と固定部材１５の厚みＴ５とが、基準厚さＴＯの半分以下となっている。すなわち、梱包ユニット１５０は、第１シート部材１１０の全体の厚みが基準厚さＴＯの半分以下となっている。よって、対向部１１ａと固定部材１５とをステープル３０で固定しても、対向部１１ａの表層のライナ等が破けないため、意匠性を損なうことなく、外力への耐性を維持することができる。 As described above, the packaging unit 150 of the second embodiment, the thickness T 1 of the first sheet member 110 including the opposing portion 11a and the thickness T 5 of the fixed member 15, and less than half the reference thickness T O Has become. That is, the packing unit 150, the total thickness of the first sheet member 110 is less than or equal to half the reference thickness T O. Therefore, even if the opposing portion 11a and the fixing member 15 are fixed with the staple 30, the liner or the like of the surface layer of the opposing portion 11a is not broken, so that it is possible to maintain the resistance to external force without impairing the design.
　また、筒状梱包材１００を構成する段ボールは、第１シート部材１１０及び固定部材１５の厚さのみが基準厚さＴＯの半分以下となっており、他の部分の厚さは基準厚さＴＯのままで維持されている。したがって、少なくとも長手方向に沿った３方向の強度を維持することができる。 Moreover, cardboard constituting the tubular packaging material 100, the thickness of the first only the thickness of the sheet member 110 and the fixing member 15 and is equal to or less than half the reference thickness T O, the other part is the reference thickness It is maintained while the T O. Therefore, it is possible to maintain the strength in at least three directions along the longitudinal direction.
　さらに、第１緩衝梱包材１２１は、固定部材１５に対向する部分に切り欠き部１２１ｋが形成されている。同様に、第２緩衝梱包材１２２は、固定部材１５に対向する部分に切り欠き部１２２ｋが形成されている。よって、固定部材１５を逃がし、第１緩衝梱包材１２１及び第２緩衝梱包材１２２と、固定部材１５及び第１シート部材１１０との間の隙間を減らすことができるため、衝撃吸収力の増加を図ることができる。 Furthermore, the first cushioning packing material 121 has a cutout portion 121k at a portion facing the fixing member 15. Similarly, the second cushioning packing material 122 has a cutout portion 122k formed at a portion facing the fixing member 15. Accordingly, the fixing member 15 is released, and the gap between the first cushioning packing material 121 and the second cushioning packing material 122 and the fixing member 15 and the first sheet member 110 can be reduced. Can be planned.
　ここで、図１８～図２０を参照して、実施の形態１及び２の梱包ユニットにより得られる効果をさらに詳細に説明する。図１８は、従来の筒状梱包材を構成する段ボールがステープルのよって留められる様子を段階的に示す説明図である。図１９は、筒状に組み立てられた従来の筒状梱包材を示す斜視図である。図２０は、図１９の筒状梱包材を上側からみた平面図である。なお、従来の筒状梱包材を構成する段ボールは、図３（ａ）及び図１２（ａ）に示すプレス加工前の段ボールと同様の厚さとなっているため、図１８～図２０では、図３（ａ）及び図１２（ａ）と共通の符号を用いて説明する。 Here, the effects obtained by the packing units of the first and second embodiments will be described in more detail with reference to FIGS. FIG. 18 is an explanatory view showing stepwise how cardboard constituting a conventional tubular packing material is fastened by staples. FIG. 19 is a perspective view showing a conventional tubular packing material assembled into a tubular shape. FIG. 20 is a plan view of the cylindrical packing material of FIG. 19 as viewed from above. Since the thickness of the corrugated cardboard constituting the conventional tubular packing material is the same as that of the corrugated cardboard before press working shown in FIGS. 3A and 12A, FIGS. The description will be made using the same reference numerals as in FIG. 3A and FIG.
　図１８（ａ）は、第１シート部材１１Ｏと固定シート部材１５Ｏとが重なった接合部にステープル３０が差し込まれた状態を示している。図１８（ｂ）は、図１８（ａ）の状態の第１シート部材１１Ｏ、固定シート部材１５Ｏ、及びステープル３０に対し、上下方向に圧が加わっている様子を示している。図１８（ｃ）は、第１シート部材１１Ｏと固定シート部材１５Ｏとがステープル３０によって留められた状態を示している。 FIG. 18 (a) shows a state in which staple 30 is inserted into the joint and the fixing sheet member 15 O and the first sheet member 11 O overlap. FIG. 18B illustrates a state where pressure is applied in the vertical direction to the first sheet member 11 O , the fixed sheet member 15 O , and the staple 30 in the state of FIG. 18A. FIG. 18 (c) shows a state in which the fixing sheet member 15 O and the first sheet member 11 O is fastened by staples 30.
　ここで、従来の第１シート部材１１Ｏ及び固定シート部材１５Ｏの厚みは基準厚さＴＯである。そのため、接合部がステープル３０によって固定される際、図１８（ｂ）に示すように、第１シート部材１１Ｏ及び固定シート部材１５Ｏにおけるステープル３０の近傍が部分的に陥没していき、図１８（ｃ）に示すように、第１シート部材１１Ｏの表面の平らな紙が避けて破れてしまう（破けＢ参照）。図１９及び図２０に示すように、破けＢは、複数のステープル３０のそれぞれから、第１シート部材１１Ｏの第４シート部材１４側の端部に亘って生じ、意匠性が著しく損なわれる。 Here, a conventional first sheet member 11 O and the fixing sheet member 15 O thickness is the reference thickness T O. Therefore, when the joint is fixed by a staple 30, as shown in FIG. 18 (b), the vicinity of the staple 30 in the first sheet member 11 O and the fixing sheet member 15 O Iki partially collapse, Fig. 18 (c), the by results (torn see B) which torn plain paper of the first sheet member 11 O on the surface avoided. As shown in FIGS. 19 and 20, torn B from each of the plurality of staples 30, it occurs over the end of the fourth sheet member 14 side of the first sheet member 11 O, design property is significantly impaired.
　この点、上記各実施の形態における梱包ユニットは、少なくとも固定部材１５が対向して配置される対向部１１ａの厚みが基準厚さＴＯの半分以下となっている。よって、接合部をステープル３０で留められる際、第１シート部材１１が凹む量が相対的に小さくなり、第１シート部材１１の表面のライナに加わる力が低減されるため、表面のライナが避けて破けるという事態を回避することができる。 In this regard, the packaging unit in the above embodiments, the thickness of the opposing portion 11a which at least the fixing member 15 is arranged to face is less than or equal to half the reference thickness T O. Therefore, when the joint is fastened by the staple 30, the amount of depression of the first sheet member 11 is relatively small, and the force applied to the liner on the surface of the first sheet member 11 is reduced. Can be avoided.
　上述した各実施の形態は、梱包ユニットにおける好適な具体例であり、本発明の技術的範囲は、これらの態様に限定されるものではない。例えば、上記各実施の形態では、対向部１１ａの厚みＴ１が基準厚さＴＯの半分以下の場合を例示したが、これに限らず、基準厚さＴＯによっては、対向部１１ａの厚みＴ１を基準厚さＴＯの半分より厚くしてもよい（ＴＯ／２＜Ｔ１＜ＴＯ）。同様に、固定部材１５の厚みＴ５は、基準厚さＴＯによっては、基準厚さＴＯの半分より厚くしてもよい（ＴＯ／２＜Ｔ５＜ＴＯ）。 Each of the above-described embodiments is a preferred specific example of the packing unit, and the technical scope of the present invention is not limited to these aspects. For example, in the above embodiments, although the thickness T 1 of the opposing portion 11a has been illustrated in the case of less than half the reference thickness T O, not limited thereto, the reference by the thickness T O, the thickness of the opposing portion 11a T 1 may be thicker than half of the reference thickness T O (T O / 2 <T 1 <T O ). Similarly, depending on the reference thickness T O , the thickness T 5 of the fixing member 15 may be larger than half of the reference thickness T O (T O / 2 <T 5 <T O ).
