Description

本発明は、１枚のシート状のブランクにより形成され、上端部に開口を有する包装箱に関するものである。   The present invention relates to a packaging box formed of a single sheet-like blank and having an opening at the upper end.

従来より、１枚のシート状のブランクにより形成され、上端部に開口を有する包装箱として、特許文献１に記載のスタッキングトレイが存在する。図１１（特許文献１中では図６）に示すように、スタッキングトレイａは、長方形状に形成された底面部ｂと、底面部ｂの各短辺部から折れ線ｃ１を介して連設された側面部ｄと、底面部ｂの各長辺部から折れ線ｃ２を介して連設された側面部ｅと、この側面部ｅの各側辺部から折れ線ｃ３を介して延設された糊代片ｆと、を有しており、短辺部側の両側面部ｄと、長辺部側の両側面部ｅとを底面部ｂの周縁に折り立てるとともに、糊代片ｆを短辺部側の側面部ｄの裏面に接着することにより、比較的底が浅いトレイ形状（特許文献１中の図５を参照）に形成されたものである。   Conventionally, there is a stacking tray described in Patent Document 1 as a packaging box that is formed of a single sheet-like blank and has an opening at the upper end. As shown in FIG. 11 (FIG. 6 in Patent Document 1), the stacking tray a is connected to the bottom surface portion b formed in a rectangular shape and the short side portions of the bottom surface portion b via the broken line c1. Side piece d, side piece e connected from each long side part of bottom face part b via broken line c2, and glue margin piece extended from each side part of this side part e via broken line c3 f, and both side surface portions d on the short side portion side and both side surface portions e on the long side portion side are folded to the periphery of the bottom surface portion b, and the adhesive margin piece f is formed on the side surface on the short side portion side. By adhering to the back surface of the part d, it is formed into a tray shape with a relatively shallow bottom (see FIG. 5 in Patent Document 1).

また、短辺部側の側面部ｄの下端である折れ線ｃ１と、この側面部ｄの上端である上辺部ｄ１との間の長さｈ１（つまり、側面部ｄの高さ方向の長さｈ１）と、長辺部側の側面部ｅの下端である折れ線ｃ２と、この側面部ｅの上端である上辺部ｅ１との間の長さｈ２（つまり、側面部ｅの高さ方向の長さｈ２）とが、略同一である。   Further, the length h1 between the broken line c1 that is the lower end of the side surface portion d on the short side portion and the upper side portion d1 that is the upper end of the side surface portion d (that is, the length h1 of the side surface portion d in the height direction). ) And a broken line c2 that is the lower end of the side surface portion e on the long side portion side and the upper side portion e1 that is the upper end of the side surface portion e (that is, the length in the height direction of the side surface portion e) h2) is substantially the same.

そして、ブランクの状態において、糊代片ｆの側辺部ｆ２で、側面部ｅ側とは反対側にて折れ線ｃ３に相対している側辺部ｆ２と、糊代片ｆに隣接している側面部ｄの上辺部ｄ１とが、同一直線上に位置しており、また、長辺部側の側面部ｅの上辺部ｅ１と、この側面部ｅに設けられている糊代片ｆの上辺部ｆ１とが、同一直線上に位置しており、つまり、当該ブランクは、方形状の全体概形（概略輪郭）を有している。   In the blank state, the side edge f2 of the adhesive margin piece f is adjacent to the adhesive margin piece f and the side edge portion f2 opposite to the broken line c3 on the side opposite to the side surface portion e side. The upper side part d1 of the side part d is located on the same straight line, and the upper side part e1 of the side part e on the long side part side and the upper side of the glue margin piece f provided on the side part e The part f1 is located on the same straight line, that is, the blank has a square overall outline (schematic outline).

しかし、特許文献１のものにおいて、底のより深いものにしたい場合には、図１１中に二点鎖線で示したように、短辺部側の側面部ｄの高さ方向の長さｈ１をこれより長いｈ３へとより長くするとともに、長辺部側の側面部ｅの高さ方向の長さｈ２をこれより長いｈ４へとより長くすることになるため、紙材から打ち抜き等の手法によりブランクを製造するに当たり、ブランクの正味に必要な紙材量が増加するばかりでなく、ブランクの全体概形（概略輪郭）が十文字形となることから、紙材に無駄が生じ、紙材損失量が増大して、コスト高となる問題がある。   However, in the case of Patent Document 1, when it is desired to make the bottom deeper, the length h1 in the height direction of the side surface portion d on the short side portion side is set as shown by a two-dot chain line in FIG. Since the length h2 is made longer to h3 and the length h2 in the height direction of the side portion e on the long side portion side is made longer to h4 longer than this, a method such as punching from paper is used. When manufacturing a blank, not only does the amount of paper necessary for the net of the blank increase, but the overall outline (rough outline) of the blank becomes a cross shape, resulting in wasted paper and the amount of paper lost. There is a problem that the cost increases.

つまり、ブランクの全体概形が方形状であれば、紙材中にブランクを形成する領域を無駄なく詰めて並べることができるが、ブランクが十文字形の場合、十文字形の入り隅部に相当する領域で、短辺部側の側面部ｄの側辺部ｄ２と、糊代片ｆの側辺部ｆ２と、短辺部側の側面部ｄの上辺部ｄ１の延長線と、糊代片ｆの上辺部ｆ１の延長線とにより囲まれた領域をブランク形成に利用することができず、製造時における紙材のロスが増大する。   That is, if the overall outline of the blank is a square, the blank forming area can be packed and arranged without waste, but if the blank is a cross-shaped, it corresponds to a cross-shaped corner of the cross-shaped. In the region, the side part d2 of the side part d on the short side part side, the side part f2 of the glue piece f, the extension line of the upper side part d1 of the side part d on the short side part, and the glue piece f The area surrounded by the extension line of the upper side part f1 cannot be used for blank formation, and the loss of paper material during manufacturing increases.

また、包装箱ａの底を深くすればするほど、短辺部側の側面部ｄの高さ方向の長さｈ３をより長くするとともに、長辺部側の側面部ｅの高さ方向の長さｈ４をより長くすることになるため、短辺部側の側面部ｄの上辺部ｄ１の位置と、糊代片ｆの側辺部ｆ２の位置との隔たり（ｈ３−ｈ１）は、更に長くなり、上記問題は益々顕著となる。   Further, the deeper the bottom of the packaging box a, the longer the length h3 in the height direction of the side part d on the short side part side, and the length in the height direction of the side part e on the long side part side. Since the length h4 is made longer, the distance (h3-h1) between the position of the upper side part d1 of the side part d on the short side part side and the position of the side part f2 of the adhesive margin piece f is longer. Thus, the above problem becomes more prominent.

そこで、本発明が解決しようとする問題点は、１枚のシート状のブランクにより形成された包箱箱で、方形状の底面部と、底面部の四方の各辺部から連設された側面部とを有する包装箱において、ブランク形成に要する紙材（ブランク形成に必要な紙材の正味とブランク形成時に生じる紙材ロス）を削減することにより、製造コストを低減することができる包装箱を提供することを目的とし、特に、側面部の高さ方向の長さが長く、深さが深い包装箱において、ブランク形成に要する紙材を削減することにより、製造コストを低減することができる包装箱を提供することを目的とするものである。   Therefore, the problem to be solved by the present invention is a packaging box formed of a single sheet-like blank, and a side surface continuously provided from a rectangular bottom surface and four sides of the bottom surface. A packaging box that can reduce manufacturing costs by reducing the paper material required for blank formation (the net of the paper material necessary for blank formation and the paper material loss that occurs during blank formation). Packaging that can reduce the manufacturing cost by reducing the paper material required for blank formation, especially in the packaging box whose length in the height direction of the side part is long and deep. The purpose is to provide a box.

つまり、第１側面部１０は、その第５折れ線Ｃ１２ａ側（第１縦桟部１２ａ形成側）にあっては、図３、図４に示すように、底面部６０と第１側面部１０との境界である第１折れ線Ｃ１０上に位置する第１基点Ｐ１０から、下記の第１第仮想線上に位置する第９基点Ｒ１０までの間に形成された第５切込みＪ７０で、第１切込みＪ６０に続けて形成された第５切込みＪ７０と、第１折れ線Ｃ１０上に位置する第３基点Ｐ２０から、第１第仮想線上に位置する第１０基点Ｒ２０で、第９基点Ｒ１０より第１折れ線Ｃ１０側寄りで、かつ、第５折れ線Ｃ１２ａ側寄りに位置する第１０基点Ｒ２０までの間に形成された第６切込みＪ７２で、第２切込みＪ６２に続けて形成された第６切込みＪ７２と、第９基点Ｒ１０から第１０基点Ｒ２０までの間に形成された第９折れ線Ｃ６０ａと、を有しており、第５切込みＪ７０と、第６切込みＪ７２と、第９折れ線Ｃ６０ａと、上記の第１折れ線第１節部Ｃ１０ａ（すなわち、第１折れ線Ｃ１０の一部）とにより、これらで囲まれた領域である支持部１６ａが形成されている。   That is, as shown in FIGS. 3 and 4, the first side surface portion 10 is located on the fifth polygonal line C12a side (the first vertical rail portion 12a formation side), as shown in FIGS. The fifth notch J70 formed from the first base point P10 located on the first broken line C10 which is the boundary of the first base line R10 to the ninth base point R10 located on the following first imaginary line, From the fifth notch J70 formed continuously and the third base point P20 located on the first broken line C10 to the tenth base point R20 located on the first imaginary line, closer to the first broken line C10 side than the ninth base point R10 In addition, a sixth cut J72 formed between the fifth cut line C12a and the tenth base point R20 located near the fifth broken line C12a, a sixth cut J72 formed following the second cut J62, and a ninth base point R10. To 10th base point R20 A ninth broken line C60a, a fifth cut J70, a sixth cut J72, a ninth broken line C60a, and the first broken line first node C10a (that is, the first broken line C10). The support portion 16a, which is a region surrounded by these, is formed.

ここで、上記の第１仮想線とは、第１折れ線Ｃ１０上の２点を通って第１折れ線Ｃ１０の長さ方向に延びる直線である第１折れ線方向線と、第３折れ線Ｃ３０上の２点を通って第３折れ線Ｃ３０の長さ方向に延びる直線である第３折れ線方向線との交点（第１交点）の近傍を通り、第１折れ線Ｃ１０の中点側にて、第１折れ線方向線に対し略４５度の角度をなす直線であり、第９折れ線Ｃ６０ａは、この第１仮想線の一部に重なっている。なお、後述するように、第１仮想線が第１交点を通る構成としてもよい。また、第１交点は、第１折れ線方向線と、第５折れ線Ｃ１２ａ上の２点を通って第５折れ線Ｃ１２ａの長さ方向に延びる直線である第５折れ線方向線との交点としてもよい。   Here, the first virtual line is a first broken line direction line that is a straight line extending in the length direction of the first broken line C10 through two points on the first broken line C10, and 2 on the third broken line C30. The first polygonal line direction passes through the vicinity of the intersection (first intersection) with the third polygonal line, which is a straight line extending in the length direction of the third polygonal line C30 through the point, on the middle point side of the first polygonal line C10. The line is a straight line having an angle of approximately 45 degrees with respect to the line, and the ninth broken line C60a overlaps a part of the first imaginary line. As will be described later, the first virtual line may pass through the first intersection. The first intersection may be an intersection between the first broken line direction line and the fifth broken line direction line that is a straight line extending in the length direction of the fifth broken line C12a through two points on the fifth broken line C12a.

なお、第９折れ線Ｃ６０ａは、包装箱５を組み立てる際、支持部１６ａの反転軸となる。こ第１仮想線及び反転の詳細については後説する。   In addition, the 9th broken line C60a becomes an inversion axis of the support portion 16a when the packaging box 5 is assembled. Details of the first virtual line and inversion will be described later.

また、第５切込みＪ７０は、第５切込み第１節部Ｊ７０１と、第５切込み第２節部Ｊ７０２ａと、第５切込み第３節部Ｊ７０２ｂと、から形成されている。第５切込み第１節部Ｊ７０１は、第１基点Ｐ１０から、第１切込みＪ６０に続けて形成され、第１折れ線Ｃ１０と直角をなす直線状で、第１切込みＪ６０の延長線上に位置している。第５切込み第２節部Ｊ７０２ａは、第５切込み第１節部Ｊ７０１の端部で、第１基点Ｐ１０側とは反対側の端部から、第５切込み第１節部Ｊ７０１に続けて形成され、第５折れ線Ｃ１２ａの上端部側に屈曲している。第５切込み第３節部Ｊ７０２ｂは、第５切込み第２節部Ｊ７０２ａの端部で、第５切込み第１節部Ｊ７０１側とは反対側の端部から、第５切込み第２節部Ｊ７０２ａに続けて、第９基点Ｒ１０までの間に一直線状に形成されている。   Further, the fifth cut J70 is formed of a fifth cut first joint J701, a fifth cut second joint J702a, and a fifth cut third joint J702b. The fifth cut first joint J701 is formed from the first base point P10 following the first cut J60, is a straight line perpendicular to the first broken line C10, and is located on the extended line of the first cut J60. . The fifth cut second node J702a is an end of the fifth cut first node J701, and is formed from the end opposite to the first base point P10 side to the fifth cut first node J701. , Bent toward the upper end side of the fifth broken line C12a. The fifth cut third node J702b is the end of the fifth cut second node J702a, and from the end opposite to the fifth cut first node J701 side to the fifth cut second node J702a. Subsequently, a straight line is formed up to the ninth base point R10.

このように、第５切込みＪ７０が形成されることにより、図８に示すように、反転後に、支持部１６ａの第１折れ線第１節部Ｃ１０ａと略直交する辺部７４ａで、第５切込み第１節部Ｊ７０１により形成された辺部（第５辺部）７４ａが、後説する第１突出部７０a の基端部にて略水平に配置され、包装箱５を補強するとともに、包装箱５を積み重ねる際、辺部７４ａにより上段側の包装箱５を支持することができる。第５切込み第１節部Ｊ７０１は第５切込み第１構成部に当たり、第５切込み第２節部Ｊ７０２ａと第５切込み第３節部Ｊ７０２ｂとで第５切込み第２構成部Ｊ７０２を構成する。   In this way, by forming the fifth cut J70, as shown in FIG. 8, at the side portion 74a substantially orthogonal to the first broken line first node C10a of the support portion 16a after the inversion, as shown in FIG. A side portion (fifth side portion) 74a formed by the one-node portion J701 is disposed substantially horizontally at the base end portion of the first projecting portion 70a, which will be described later, and reinforces the packaging box 5, and the packaging box 5 , The upper packaging box 5 can be supported by the side 74a. The fifth cut first node J701 corresponds to the fifth cut first component, and the fifth cut second node J702a and the fifth cut third node J702b constitute a fifth cut second component J702.

また、第９基点Ｒ１０から第１３切込みＪ７０４が形成されている。この第１３切込みＪ７０４は、半円弧形状を有し、一方の端部が第９基点Ｒ１０にて第５切込み第３節部Ｊ７０２ｂに連続し、湾曲頂部が第９基点Ｒ１０側とは反対側に突出し、他方の端部で、第９基点Ｒ１０側とは反対側の端部が第１０基点Ｒ２０側とは反対側（支持部１６ａの外側）に形成されている。つまり、第１３切込みＪ７０４は、第９基点Ｒ１０にて第５切込み第３節部Ｊ７０２ｂに連続してはいるが、第５切込み第３節部Ｊ７０２ｂの長さ方向とは異なる方向に形成されている。   A thirteenth notch J704 is formed from the ninth base point R10. The thirteenth cut J704 has a semicircular arc shape, one end is continuous with the fifth cut third joint J702b at the ninth base point R10, and the curved top is opposite to the ninth base point R10 side. It protrudes and, at the other end, the end opposite to the ninth base point R10 side is formed on the side opposite to the tenth base point R20 side (outside of the support portion 16a). That is, the thirteenth cut J704 is continuous with the fifth cut third joint J702b at the ninth base point R10, but is formed in a direction different from the length direction of the fifth cut third joint J702b. Yes.

また、第１０基点Ｒ２０から第１４切込みＪ７２１が形成されている。この第１４切込みＪ７２１は、半円弧形状を有し、一方の端部が第１０基点Ｒ２０にて第６切込みＪ７２に連続し、湾曲頂部が第１０基点Ｒ２０側とは反対側に突出し、他方の端部で、第１０基点Ｒ２０側とは反対側の端部が第９基点Ｒ１０側とは反対側（支持部１６ａの外側）に形成されている。つまり、第１４切込みＪ７２１は、第１０基点Ｒ２０にて第６切込みＪ７２に連続してはいるが、第６切込みＪ７２の長さ方向とは異なる方向に形成されている。   Further, a fourteenth cut J721 is formed from the tenth base point R20. The fourteenth cut J721 has a semicircular arc shape, one end is continuous with the sixth cut J72 at the tenth base point R20, the curved top protrudes on the side opposite to the tenth base point R20 side, At the end, the end opposite to the tenth base point R20 side is formed on the side opposite to the ninth base point R10 side (outside of the support portion 16a). In other words, the fourteenth cut J721 is continuous with the sixth cut J72 at the tenth base point R20, but is formed in a direction different from the length direction of the sixth cut J72.

このように、第９基点Ｒ１０から第１３切込みＪ７０４が形成されているとともに、第１０基点Ｒ２０から第１４切込みＪ７２１が形成されていることにより、第９基点Ｒ１０及び第１０基点Ｒ２０から裂傷が発生することを防止できる。   As described above, the thirteenth cut J704 is formed from the ninth base point R10, and the fourteenth cut J721 is formed from the tenth base point R20, so that a laceration occurs from the ninth base point R10 and the tenth base point R20. Can be prevented.

つまり、支持部１６ａを反転させる際（図８、図９を参照）には、第９折れ線Ｃ６０ａ側から第１折れ線第１節部Ｃ１０ａ側に向かって支持部１６ａを引っ張る力（張力）が第９折れ線Ｃ６０ａ付近にかかり、特に支持部１６ａの回動角度が９０度を超えると、上記張力の向きが、第９折れ線Ｃ６０ａ付近を第５折れ線Ｃ１２ａの上端部側に引っ張る向きへと変化し、つまり、第９折れ線Ｃ６０ａ付近をめくりあげようとする力が第１側面本体部１４にかかることになるが、第１３切込みＪ７０４が第５切込み第３節部Ｊ７０２ｂの長さ方向とは異なる方向に形成されているとともに、第１４切込みＪ７２１が第６切込みＪ７２の長さ方向とは異なる方向に形成されていることから、第１３切込みＪ７０４の端部で、第９基点Ｒ１０側とは反対側の端部と、第１４切込みＪ７２１の端部で、第１０基点Ｒ２０側とは反対側の端部とに、上記張力がかからない。   That is, when the support portion 16a is reversed (see FIGS. 8 and 9), the force (tension) that pulls the support portion 16a from the ninth broken line C60a side toward the first bent line first joint C10a side is the first. When the rotation angle of the support portion 16a exceeds 90 degrees, especially when the rotation angle of the support portion 16a exceeds 90 degrees, the direction of the tension changes to the direction of pulling the vicinity of the ninth broken line C60a toward the upper end portion side of the fifth broken line C12a, That is, a force to turn up the vicinity of the ninth broken line C60a is applied to the first side surface main body 14, but the thirteenth cut J704 is in a direction different from the length direction of the fifth cut third joint J702b. Since the 14th cut J721 is formed in a direction different from the length direction of the 6th cut J72, the end of the 13th cut J704 is opposite to the ninth base point R10 side. And the end side, at the end of the 14 cuts J721, to the tenth reference point R20 side and the opposite end, the tension is not applied.

さらに、第１３切込みＪ７０４と第１４切込みＪ７２１とが、半円弧形状に形成されていることから、張力の作用点が一箇所に定まることなく、反転途中の支持部１６ａが第１側面本体部１４となす角度や、反転時に伴う僅かなねじれ等による支持部１６ａの姿勢変化によって、張力の作用点が半円弧形状中のいずれかの箇所に変動し、第１側面本体部１４の特定の箇所に負担がかからず、特定箇所から裂けてしまうことが防止される。   Further, since the thirteenth notch J704 and the fourteenth notch J721 are formed in a semicircular arc shape, the supporting portion 16a in the middle of the inversion is fixed to the first side surface main body portion 14 without the point of action of tension being determined at one place. Due to a change in the posture of the support portion 16a due to the angle to be twisted or a slight torsion during reversal, the point of action of the tension changes to any location in the semicircular arc shape, and at a specific location on the first side body portion 14 There is no burden and it is prevented from tearing from a specific location.

また、第６折れ線Ｃ１２ｂ側（第２縦桟部１２ｂ形成側）にあっては、図３、図５に示すように、底面部６０と第１側面部１０との境界である第１折れ線Ｃ１０上に位置する第５基点Ｐ３０から、下記の第２仮想線上に位置する第１１基点Ｒ３０までの間に形成された第７切込みＫ７０で、第３切込みＫ６０に続けて形成された第７切込みＫ７０と、第１折れ線Ｃ１０上に位置する第７基点Ｐ４０から、第２仮想線上に位置する第１２基点Ｒ４０で、第１１基点Ｒ３０より第１折れ線Ｃ１０側寄りで、かつ、第６折れ線Ｃ１２ｂ側寄りに位置する第１２基点Ｒ４０までの間に形成された第８切込みＫ７２で、第４切込みＫ６２に続けて形成された第８切込みＫ７２と、第１１基点Ｒ３０から第１２基点Ｒ４０までの間に形成された第１０折れ線Ｃ６０ｂと、を有しており、第７切込みＫ７０と、第８切込みＫ７２と、第１０折れ線Ｃ６０ｂと、上記の第１折れ線第２節部Ｃ１０ｂ（すなわち、第１折れ線Ｃ１０の一部）とにより、これらで囲まれた領域である支持部１６ｂが形成されている。   Further, on the sixth broken line C12b side (the second vertical beam portion 12b forming side), as shown in FIGS. 3 and 5, the first broken line C10 that is the boundary between the bottom surface portion 60 and the first side surface portion 10. A seventh cut K70 formed between the fifth base point P30 located above and the eleventh base point R30 located on the following second imaginary line, and formed following the third cut K60. From the seventh base point P40 located on the first broken line C10 to the twelfth base point R40 located on the second imaginary line, closer to the first broken line C10 side than the eleventh basic point R30 and closer to the sixth broken line C12b side The eighth cut K72 formed between the 12th base point R40 and the 8th cut K72 formed after the 4th cut K62, and the 11th base point R30 to the 12th base point R40. 10th fold C60b, and a seventh cut K70, an eighth cut K72, a tenth broken line C60b, and the first bent line second node C10b (that is, a part of the first bent line C10). A support portion 16b, which is a region surrounded by these, is formed.

ここで、上記の第２仮想線とは、上記の第１折れ線方向線と、第４折れ線Ｃ４０上の２点を通って第４折れ線Ｃ４０の長さ方向に延びる直線である第４折れ線方向線との交点（第２交点）の近傍を通り、第１折れ線Ｃ１０の中点側にて、第１折れ線方向線に対し略４５度の角度をなす直線であり、第１０折れ線Ｃ６０ｂは、この第２仮想線の一部に重なっている。なお、後述するように、第２仮想線が第２交点を通る構成としてもよい。また、第２交点は、第１折れ線方向線と、第６折れ線Ｃ１２ｂ上の２点を通って第６折れ線Ｃ１２ｂの長さ方向に延びる直線である第６折れ線方向線との交点としてもよい。   Here, the second imaginary line is the first broken line direction line and the fourth broken line direction line that is a straight line extending in the length direction of the fourth broken line C40 through two points on the fourth broken line C40. Is a straight line that passes through the vicinity of the first intersection line (second intersection point) and forms an angle of approximately 45 degrees with respect to the first broken line direction line on the middle point side of the first broken line C10. The tenth broken line C60b 2 Overlaps part of the imaginary line. As will be described later, the second virtual line may pass through the second intersection. The second intersection point may be an intersection point between the first broken line direction line and the sixth broken line direction line that is a straight line extending in the length direction of the sixth broken line C12b through two points on the sixth broken line C12b.

なお、第１０折れ線Ｃ６０ｂは、包装箱５を組み立てる際、支持部１６ｂの反転軸となる。この第２仮想線及び反転の詳細については後説する。   In addition, the 10th broken line C60b becomes an inversion axis of the support portion 16b when the packaging box 5 is assembled. Details of the second virtual line and inversion will be described later.

The third intersection point may be an intersection point of the second broken line direction line and the seventh broken line direction line that is a straight line extending in the length direction of the seventh broken line C22a through two points on the seventh broken line C22a.

なお、第１１折れ線Ｃ７０ａは、包装箱５を組み立てる際、支持部２６ａの反転軸となる。この第３仮想線及び反転の詳細については後説する。   Note that the eleventh broken line C70a serves as the reverse axis of the support portion 26a when the packaging box 5 is assembled. Details of the third virtual line and inversion will be described later.

また、第９切込みＪ８０は、第９切込み第１節部Ｊ８０１と、第９切込み第２節部Ｊ８０２ａと、第９切込み第３節部Ｊ８０２ｂと、から形成されている。第９切込み第１節部Ｊ８０１は、第２基点Ｑ１０から、第１切込みＪ６０に続けて形成され、第２折れ線Ｃ２０と直角をなす直線状で、第１切込みＪ６０の延長線上に位置している。第９切込み第２節部Ｊ８０２ａは、第９切込み第１節部Ｊ８０１の端部で、第２基点Ｑ１０側とは反対側の端部から、第９切込み第１節部Ｊ８０１に続けて形成され、第７折れ線Ｃ２２ａの上部側に屈曲している。第９切込み第３節部Ｊ８０２ｂは、第９切込み第２節部Ｊ８０２ａの端部で、第９切込み第１節部Ｊ８０１側とは反対側の端部から、第９切込み第２節部Ｊ８０２ａに続けて、第１３基点Ｓ１０までの間に一直線状に形成されている。   The ninth cut J80 is formed of a ninth cut first joint J801, a ninth cut second joint J802a, and a ninth cut third joint J802b.

The ninth notch third node J802b is the end of the ninth notch second node J802a and from the end opposite to the ninth notch first node J801 side to the ninth notch second node J802a. Subsequently, a straight line is formed up to the thirteenth base point S10.

また、第１３基点Ｓ１０から第１７切込みＪ８０４が形成されている。この第１７切込みＪ８０４は、半円弧形状を有し、一方の端部が第１３基点Ｓ１０にて第９切込み第３節部Ｊ８０２ｂに連続し、湾曲頂部が第１３基点Ｓ１０側とは反対側に突出し、他方の端部で、第１３基点Ｓ１０側とは反対側の端部が第１４基点Ｓ２０側とは反対側（支持部２６ａの外側）に形成されている。つまり、第１７切込みＪ８０４は、第１３基点Ｓ１０にて第９切込み第３節部Ｊ８０２ｂに連続してはいるが、第９切込み第３節部Ｊ８０２ｂの長さ方向とは異なる方向に形成されている。   In addition, a seventeenth cut J804 is formed from the thirteenth base point S10. The seventeenth cut J804 has a semicircular arc shape, one end of which is continuous with the ninth cut third joint J802b at the thirteenth base point S10, and the curved top is opposite to the thirteenth base point S10 side. It protrudes and, at the other end, the end opposite to the thirteenth base point S10 side is formed on the side opposite to the fourteenth base point S20 side (outside of the support portion 26a). That is, the seventeenth cut J804 is continuous with the ninth cut third joint J802b at the thirteenth base point S10, but is formed in a direction different from the length direction of the ninth cut third joint J802b. Yes.

このように、第５切込みＪ８０が形成されることにより、上記支持部１６ａの場合と同様に、反転後に、支持部２６ａの第２折れ線第１節部Ｃ２０ａと略直交する辺部７４ｃで、第９切込み第１節部Ｊ８０１により形成された辺部７４ｃが、後説する第３突出部７０ｃの基端部にて略水平に配置され、包装箱５を補強するとともに、包装箱５を積み重ねる際、辺部（第７辺部）７４ｃにより上段側の包装箱５を支持することができる。第９切込み第１節部Ｊ８０１は第９切込み第１構成部に当たり、第９切込み第２節部Ｊ８０２ａと第９切込み第３節部Ｊ８０２ｂとで第９切込み第２構成部Ｊ８０２を構成する。   In this way, by forming the fifth cut J80, as in the case of the support portion 16a, after the inversion, the side portion 74c substantially orthogonal to the second broken line first node portion C20a of the support portion 26a When the side portion 74c formed by the 9-cut first knot portion J801 is disposed substantially horizontally at the base end portion of the third projecting portion 70c, which will be described later, while reinforcing the packaging box 5 and stacking the packaging boxes 5 The upper packaging box 5 can be supported by the side (seventh side) 74c. The ninth cut first node J801 corresponds to the ninth cut first component, and the ninth cut second node J802a and the ninth cut third node J802b constitute the ninth cut second component J802.

The eighteenth cut J821 has a semicircular arc shape, one end of which is continuous with the tenth cut J82 at the fourteenth base point S20, the curved top protrudes on the side opposite to the fourteenth base point S20 side, At the end, an end opposite to the 14th base point S20 side is formed on the side opposite to the 13th base point S10 side (outside of the support portion 26a). In other words, the eighteenth cut J821 is formed in a direction different from the length direction of the tenth cut J82, although it continues to the tenth cut J82 at the fourteenth base point S20.

このように、第１３基点Ｓ１０から第１７切込みＪ８０４が形成されているとともに、第１４基点Ｓ２０から第１８切込みＪ８２１が形成されていることにより、第１３基点Ｓ１０及び第１４基点Ｓ２０から裂傷が発生することを防止できる。   As described above, the 17th notch J804 is formed from the 13th base point S10, and the 18th notch J821 is formed from the 14th base point S20, so that a laceration occurs from the 13th base point S10 and the 14th base point S20.

このように、支持部１６ａ及び支持部２６ａと一体の第１横桟部６４ａは、支持部１６ａと支持部２６ａとが反転することにより、これらに連動して第３側面部３０側へ略９０度回動し、第３側面部３０の上方にて、第３側面部３０に対し略平行に配置され、第１横桟部６４ａの第１折れ線第１節部Ｃ１０ａ側は、支持部１６ａにより持され、第１横桟部６４ａの第２折れ線第１節部Ｃ２０ａ側は、支持部２６ａにより支持されている。   As described above, the first horizontal rail portion 64a integrated with the support portion 16a and the support portion 26a is approximately 90 toward the third side surface portion 30 side in conjunction with the inversion of the support portion 16a and the support portion 26a. And is disposed substantially parallel to the third side surface portion 30 above the third side surface portion 30, and the first broken line first joint C10a side of the first horizontal rail portion 64a is supported by the support portion 16a. The second bent line first joint C20a side of the first horizontal crossing 64a is supported by the support 26a.

つまり、第３側面部３０側へ略９０度回動した後の第１横桟部６４ａは、その内外面部を略垂直に立てた状態（回動前には第１切込みＪ６０側であった辺部を上側とし、回動前には第２切込みＪ６２側であった辺部を下側とした状態）となり、第１側面部１０側では、第１横桟部６４ａの内側の面部（回動前には底面部６０の外側面の一部であった面部）と、支持部１６ａの内側の面部（反転前には第１側面部１０の外側面の一部であった面部）とが略直角をなし、略垂直状態の第１折れ線第１節部Ｃ１０ａが略垂直状態の第５折れ線Ｃ１２ａの近傍に重なっている。   That is, the first horizontal crosspiece 64a after being rotated by approximately 90 degrees toward the third side face 30 is in a state where its inner and outer surfaces are substantially vertical (the side that was on the first cut J60 side before turning). And the side portion that was on the second cut J62 side before the rotation is the lower side), and on the first side surface portion 10 side, the inner surface portion of the first horizontal beam portion 64a (the rotation) The front surface portion that was a part of the outer surface of the bottom surface portion 60) and the inner surface portion of the support portion 16a (the surface portion that was a part of the outer surface of the first side surface portion 10 before reversal) are approximately. The first bent line first node C10a in a substantially vertical state overlaps the vicinity of the substantially vertical fifth bent line C12a.

また、第２側面部２０側では、第１横桟部６４ａの内側の面部と、支持部２６ａの内側の面部（反転前には第２側面部２０の外側面の一部であった面部）とが略直角をなし、略垂直状態の第２折れ線第１節部Ｃ２０ａが略垂直状態の第７折れ線Ｃ２２ａの近傍に重なっている。   Further, on the second side surface portion 20 side, the inner surface portion of the first horizontal crosspiece portion 64a and the inner surface portion of the support portion 26a (the surface portion that was a part of the outer surface of the second side surface portion 20 before inversion). Are substantially perpendicular to each other, and the second bent line first node C20a in the substantially vertical state overlaps with the vicinity of the seventh bent line C22a in the substantially vertical state.

また、上記のように、第３折れ線Ｃ３０と第１切込みＪ６０との間隔の長さである第９長さＨ９と、第１側面部１０の高さ方向の長さである第１長さＨ１と、第２側面部２０の高さ方向の長さである第２長さＨ２とは略同一の長さであるので、回動後の第１横桟部６４ａの上側の辺部と、第１側面部１０の上辺部１４ｃと、第２側面部２０の上辺部２４ｃとは、略同一の高さに位置している。つまり、第１横桟部６４ａの上端の高さを第１側面部１０の上端の高さや第２側面部２０の上端の高さと揃えることができる。   Further, as described above, the ninth length H9 which is the length of the interval between the third broken line C30 and the first cut J60, and the first length H1 which is the length of the first side surface portion 10 in the height direction. And the second length H2 that is the length in the height direction of the second side surface portion 20 is substantially the same length, and therefore, the side portion on the upper side of the first horizontal rail portion 64a after the rotation, The upper side portion 14c of the first side surface portion 10 and the upper side portion 24c of the second side surface portion 20 are located at substantially the same height. That is, the height of the upper end of the first horizontal crosspiece 64 a can be made equal to the height of the upper end of the first side surface portion 10 and the height of the upper end of the second side surface portion 20.

また、第１横桟部６４ａの外側の面部（回動前には底面部６０の内側面の一部であった面部）における第１折れ線第１節部Ｃ１０ａ側の端部と、第１縦桟部１２ａの内側の面部の上端部とが接着され、第１横桟部６４ａの外側の面部における第２折れ線第１節部Ｃ２０ａ側の端部と、第３縦桟部２２ａの内側の面部の上端部とが接着されている。なお、第１縦桟部１２ａの内側の面と第３側面部３０の外側の面とを接着するとともに、第３縦桟部２２ａの内側の面と第３側面部３０の外側の面とを接着するようにしてもよい。   Further, an end portion on the first broken line first joint C10a side in the outer surface portion of the first horizontal rail portion 64a (the surface portion that was a part of the inner surface of the bottom surface portion 60 before the rotation), and the first vertical The upper end portion of the inner surface portion of the crosspiece portion 12a is bonded, the end portion on the second broken line first joint C20a side in the outer surface portion of the first horizontal crosspiece portion 64a, and the inner surface portion of the third vertical crosspiece portion 22a.

You may make it adhere | attach.

なお、上記のように、支持部１６ａの回動基端である第９折れ線Ｃ６０ａは、第１仮想線上に位置している。この第１仮想線とは、第１折れ線Ｃ１０上の２点を通って第１折れ線Ｃ１０の長さ方向に延びる直線である第１折れ線方向線と、第５折れ線Ｃ１２ａ上の２点を通って第５折れ線Ｃ１２ａの長さ方向に延びる直線である第５折れ線方向線との交点の近傍を通り、第１折れ線Ｃ１０の中点側にて、第１折れ線方向線に対し略４５度の角度をなす直線である。   As described above, the ninth broken line C60a that is the rotation base end of the support portion 16a is located on the first imaginary line. The first imaginary line passes through two points on the first broken line C10, the first broken line direction line that is a straight line extending in the length direction of the first broken line C10, and the two points on the fifth broken line C12a. An angle of about 45 degrees with respect to the first broken line direction line passes through the vicinity of the intersection with the fifth broken line direction line, which is a straight line extending in the length direction of the fifth broken line C12a, at the midpoint side of the first broken line C10. It is a straight line.

また、第１折れ線方向線と第５折れ線方向線とは、略９０度の角度をなし、また、組み立てた状態では、第１縦桟部１２ａは、底面部６０に対し略垂直である。   Further, the first broken line direction line and the fifth broken line direction line form an angle of approximately 90 degrees, and the assembled first state is that the first vertical rail portion 12 a is substantially perpendicular to the bottom surface portion 60.

よって、第９折れ線Ｃ６０ａを軸とし、支持部１６ａを第１縦桟部１２ａの上端部側へ略１８０度回動させれば、第１折れ線方向線上の線分である第１折れ線第１節部Ｃ１０ａは、第５折れ線Ｃ１２ａに対し平行となる。   Therefore, if the support portion 16a is rotated approximately 180 degrees toward the upper end side of the first vertical beam portion 12a with the ninth broken line C60a as an axis, the first broken line first section which is a line segment on the first broken line direction line. The part C10a is parallel to the fifth broken line C12a.

また、支持部２６ａの回動基端である第１１折れ線Ｃ７０ａは、第３仮想線上に位置している。この第３仮想線とは、第２折れ線Ｃ２０上の２点を通って第２折れ線Ｃ２０の長さ方向に延びる直線である第２折れ線方向線と、第７折れ線Ｃ２２ａ上の２点を通って第７折れ線Ｃ２２ａの長さ方向に延びる直線である第７折れ線方向線との交点の近傍を通り、第２折れ線Ｃ２０の中点側にて、第２折れ線方向線に対し略４５度の角度をなす直線である。   Further, the eleventh broken line C70a that is the rotation base end of the support portion 26a is located on the third imaginary line. The third imaginary line passes through two points on the second broken line C20, passes through the second broken line direction line that is a straight line extending in the length direction of the second broken line C20, and passes through two points on the seventh broken line C22a. An angle of approximately 45 degrees with respect to the second broken line direction line passes through the vicinity of the intersection with the seventh broken line direction line, which is a straight line extending in the length direction of the seventh broken line C22a, at the midpoint side of the second broken line C20. It is a straight line.

また、第２折れ線方向線と第７折れ線方向線とは、略９０度の角度をなし、また、組み立てた状態では、第３縦桟部２２ａは、底面部６０に対し略垂直である。   Further, the second broken line direction line and the seventh broken line direction line form an angle of approximately 90 degrees, and the third vertical rail portion 22a is substantially perpendicular to the bottom surface portion 60 in the assembled state.

よって、第１１折れ線Ｃ７０ａを軸とし、支持部２６ａを第３縦桟部２２ａの上端部側へ略１８０度回動させれば、第２折れ線方向線上の線分である第２折れ線第１節部Ｃ１０ａは、第７折れ線Ｃ２２ａに対し平行となる。   Therefore, if the support portion 26a is rotated by approximately 180 degrees toward the upper end side of the third vertical rail portion 22a with the eleventh broken line C70a as an axis, the second bent line first section which is a line segment on the second broken line direction line. The part C10a is parallel to the seventh broken line C22a.

そして、第１横桟部６４ａは、第１仮想線と第１折れ線方向線との交点と、第３仮想線と第２折れ線方向線との交点とを結ぶ線分を軸とし、ブランク状態における元の位置（第１底面構成部６６ａと第３底面構成部６６ｃとの間の位置）から、第３側面部３０側へ９０度回動する。   And the 1st horizontal crosspiece part 64a makes the axis | shaft the line segment which connects the intersection of a 1st virtual line and a 1st broken line direction line, and the intersection of a 3rd virtual line and a 2nd broken line direction line, in a blank state From the original position (position between the first bottom surface constituting portion 66a and the third bottom surface constituting portion 66c), it is turned 90 degrees toward the third side face portion 30 side.

この第１仮想線と第１折れ線方向線との交点の位置と、第３仮想線と第２折れ線方向線との交点の位置については、ブランク形成に使用される紙材の厚み、抗折強度等の曲げ加工の容易性に影響を及ぼす特性を考慮し決定する必要がある。   About the position of the intersection of this 1st imaginary line and the 1st broken line direction line, and the position of the intersection of the 3rd imaginary line and the 2nd broken line direction line, the thickness of the paper material used for blank formation, and the bending strength It is necessary to determine in consideration of characteristics that affect the ease of bending such as.

例えば、紙材が薄く抗折強度が低い場合は、第１仮想線と第１折れ線方向線との交点の位置を、第１折れ線方向線と第３折れ線方向線との交点の位置に一致させ（つまり、第１仮想線が、第１折れ線方向線と第３折れ線方向線との交点を通る）、第３仮想線と第２折れ線方向線との交点の位置を、第２折れ線方向線と第３折れ線方向線との交点の位置に一致させれば（つまり、第３仮想線が、第２折れ線方向線と第３折れ線方向線との交点を通る）、第１横桟部６４ａが第１縦桟部１２ａ及び第３縦桟部２２ａに具合よく当接して接着されるが、紙材が厚い場合や、紙材が薄くても抗折強度が高い場合などには、上記のように交点位置を一致させると、第１横桟部６４ａが第１縦桟部１２ａ及び第３縦桟部２２ａを押圧して包装箱５に歪みが生じてしまったり、第１横桟部６４ａが第１縦桟部１２ａ及び第３縦桟部２２ａに十分に接触せず、接着強度を確保できなくなることもあり得るため、第１縦桟部１２ａ及び第３縦桟部２２ａへの第１横桟部６４ａの当たり具合を調整するべく、紙材特性を考慮した上で、第１仮想線と第１折れ線方向線との交点の位置については、第１折れ線方向線と第５折れ線方向線との交点の近傍内にて適宜決定する必要があり、第３仮想線と第２折れ線方向線との交点の位置については、第２折れ線方向線と第７折れ線方向線との交点の近傍内にて適宜決定する必要がある。   For example, when the paper material is thin and the bending strength is low, the position of the intersection of the first imaginary line and the first broken line direction line is made to coincide with the position of the intersection of the first broken line direction line and the third broken line direction line. (That is, the first imaginary line passes through the intersection of the first broken line direction line and the third broken line direction line), and the position of the intersection of the third imaginary line and the second broken line direction line is defined as the second broken line direction line. If it coincides with the position of the intersection with the third broken line direction line (that is, the third imaginary line passes through the intersection of the second broken line direction line and the third broken line direction line), the first horizontal beam portion 64a The 1 vertical beam portion 12a and the third vertical beam portion 22a are in good contact with each other and bonded. However, when the paper material is thick or when the bending strength is high even if the paper material is thin, as described above. When the intersection positions are matched, the first horizontal beam portion 64a presses the first vertical beam portion 12a and the third vertical beam portion 22a, and the packaging box 5 is distorted. Or the first horizontal beam portion 64a may not sufficiently contact the first vertical beam portion 12a and the third vertical beam portion 22a, and the adhesive strength may not be secured. And in order to adjust the contact of the first horizontal beam portion 64a to the third vertical beam portion 22a, considering the paper material characteristics, the position of the intersection of the first imaginary line and the first broken line direction line, It is necessary to determine appropriately within the vicinity of the intersection of the first broken line direction line and the fifth broken line direction line, and the position of the intersection of the third imaginary line and the second broken line direction line is the second broken line direction line and It is necessary to determine appropriately within the vicinity of the intersection with the seventh broken line direction line.

また、第１側面部１０での第４側面部４０側の第１０折れ線Ｃ６０ｂと、第２側面部２０での第４側面部４０側の第１２折れ線Ｃ７０ｂにて、谷折りするとともに、第１側面部１０側の第１折れ線第２節部Ｃ１０ｂと、第２側面部２０側の第２折れ線第２節部Ｃ２０ｂにて、山折りすることにより、底面部６０から抜き出された第２横桟部６４ｂが第４側面部４０側に回動し、立設状態の第４側面部４０の上方にて、第１側面部１０から抜き出された支持部１６ｂと、第２側面部２０から抜き出された第２横桟部第２支持部２６ｂとにより支持されている。   In addition, the first side surface portion 10 is valley-folded at the tenth fold line C60b on the fourth side surface portion 40 side and the twelfth fold line C70b on the fourth side surface portion 40 side in the second side surface portion 20, and is first folded. The second horizontal line extracted from the bottom surface portion 60 by mountain folding at the first broken line second node portion C10b on the side surface portion 10 side and the second broken line second node portion C20b on the second side surface portion 20 side. The crosspiece 64b rotates to the fourth side surface 40 side, above the fourth side surface 40 in the standing state, and from the support portion 16b extracted from the first side surface 10 and the second side surface 20. It is supported by the extracted second horizontal rail portion second support portion 26b.

つまり、図３、図５、図８、図９に示すように、支持部１６ｂは、第１０折れ線Ｃ６０ｂにて、谷折りするとともに、第１折れ線第２節部Ｃ１０ｂにて、山折りすることにより、第１０折れ線Ｃ６０ｂを軸とし、ブランク状態における支持部１６ｂの元の位置（第１側面本体部１４内に収まっている状態での位置）から第６折れ線Ｃ１２ｂの上端部側（つまり、第２縦桟部１２ｂの上端部側）へ略１８０度回動して反転する
この時、第２側面部２０側では、支持部２６ｂが、第１側面部１０側での支持部１６ｂと同様に動作し反転する。 That is, as shown in FIGS. 3, 5, 8, and 9, the support portion 16 b is folded at the valley at the tenth broken line C <b> 60 b and at the first bent line at the second knot portion C <b> 10 b. Thus, with the tenth broken line C60b as the axis, the upper end side of the sixth broken line C12b (that is, the first position from the original position of the support portion 16b in the blank state) At this time, on the second side surface 20 side, the support portion 26b is the same as the support portion 16b on the first side surface portion 10 side. Operates and reverses.

つまり、図３、図５、図８に示されるように、支持部２６ｂは、第１２折れ線Ｃ７０ｂを谷折りするとともに、第２折れ線第２節部Ｃ２０ｂを山折りすることにより、第１２折折れ線Ｃ７０ｂを軸とし、ブランク状態における支持部２６ｂの元の位置（第２側面本体部２４内に収まっている状態での位置）から第８折れ線Ｃ２２ｂの上端部側（つまり、第４縦桟部２２ｂの上端部側）へ略１８０度回動して反転する。   That is, as shown in FIGS. 3, 5, and 8, the support portion 26 b folds the twelfth fold line C <b> 70 b and folds the second fold line second knot portion C <b> 20 b to twelfth fold line. Centering on C70b, from the original position of the support portion 26b in the blank state (position in the state where the support portion 26b is accommodated in the second side body portion 24) to the upper end portion side of the eighth broken line C22b (that is, the fourth vertical beam portion 22b) Rotate approximately 180 degrees to the upper end side) and reverse.

ここで、第１横桟部６４ｂは、第３切込みＫ６０と、第４切込みＫ６２と、第１折れ線第２節部Ｃ１０ｂと、第２折れ線第２節部Ｃ２０ｂとにより囲まれた領域であり、支持部１６ｂは、第３切込みＫ６０に続けて形成された第７切込みＫ７０と、第４切込みＫ６２に続けて形成された第８切込みＫ７２と、第１０折れ線Ｃ６０ｂと、第１折れ線第２節部Ｃ１０ｂとにより囲まれた領域であり、支持部２６ｂは、第３切込みＫ６０に続けて形成された第１１切込みＫ８０と、第４切込みＫ６２に続けて形成された第１２切込みＫ８２と、第１２折れ線Ｃ７０ｂと、第２折れ線第２節部Ｃ２０ｂとにより囲まれた領域であり、つまり、第１横桟部６４ｂと、支持部１６ｂとは、第１折れ線第２節部Ｃ１０ｂを介して連続しており、また、第２横桟部６４ｂと、支持部２６ｂとは、第２折れ線第２節部Ｃ２０ｂを介して連続しており、第１横桟部６４ｂと、支持部１６ｂと、支持部２６ｂとは、一体のものである。   Here, the first horizontal cross section 64b is a region surrounded by the third cut K60, the fourth cut K62, the first broken line second joint C10b, and the second broken line second joint C20b, The support portion 16b includes a seventh cut K70 formed following the third cut K60, an eighth cut K72 formed subsequent to the fourth cut K62, a tenth broken line C60b, and a first bent line second joint.

C70b and a region surrounded by the second broken line second node C20b, that is, the first horizontal beam portion 64b and the support portion 16b are continuously connected via the first broken line second node C10b. And second side The part 64b and the support part 26b are continuous via the second broken line second node part C20b, and the first horizontal rail part 64b, the support part 16b, and the support part 26b are integrated. .

このように、支持部１６ｂ及び支持部２６ｂと一体の第２横桟部６４ｂは、支持部１６ｂと支持部２６ｂとが反転することにより、これらに連動して第４側面部４０側へ略９０度回動して、第４側面部４０の上方にて、第４側面部４０に対し略平行に配置され、第２横桟部６４ｂの第１折れ線第２節部Ｃ１０ｂ側は、支持部１６ｂにより支持され、第２横桟部６４ｂの第２折れ線第２節部Ｃ２０ｂ側は、支持部２６ｂにより支持されている。   As described above, the second horizontal beam portion 64b integrated with the support portion 16b and the support portion 26b is approximately 90 toward the fourth side surface portion 40 side in conjunction with the inversion of the support portion 16b and the support portion 26b.

The second broken line second node C20b side of the second horizontal rail portion 64b is supported by the support portion 26b.

つまり、第４側面部４０側へ略９０度回動した後の第２横桟部６４ｂは、その内外面部を略垂直に立てた状態（回動前には第３切込みＫ６０側であった辺部を上側とし、回動前には第４切込みＫ６２側であった辺部を下側とした状態）となり、第１側面部１０側では、第２横桟部６４ｂの内側の面部（回動前には底面部６０の外側面の一部であった面部）と、支持部１６ｂの内側の面部（反転前には第１側面部１０の外側面の一部であった面部）とが略直角をなし、略垂直状態の第１折れ線第２節部Ｃ１０ｂが略垂直状態の第６折れ線Ｃ１２ｂの近傍に重なっている。   In other words, the second horizontal beam portion 64b after being rotated by approximately 90 degrees toward the fourth side surface portion 40 is in a state where the inner and outer surface portions thereof are substantially vertical (the side that was on the third cut K60 side before the rotation). And the side portion that was on the side of the fourth cut K62 before turning is the lower side), and on the first side surface portion 10 side, the inner surface portion of the second horizontal rail portion 64b (turning) The front surface portion that was a part of the outer surface of the bottom surface portion 60) and the inner surface portion of the support portion 16b (the surface portion that was a part of the outer surface of the first side surface portion 10 before reversal) are approximately. The first bent line second node C10b in a substantially vertical state overlaps the vicinity of the sixth bent line C12b in a substantially vertical state.

また、第２側面部２０側では、第２横桟部６４ｂの内側の面部と、支持部２６ｂの内側の面部（反転前には第２側面部２０の外側面の一部であった面部）とが略直角をなし、略垂直状態の第２折れ線第２節部Ｃ２０ｂが略垂直状態の第８折れ線Ｃ２２ｂの近傍に重なっている。   Further, on the second side surface portion 20 side, the inner surface portion of the second horizontal rail portion 64b and the inner surface portion of the support portion 26b (the surface portion that was a part of the outer surface of the second side surface portion 20 before inversion). Are substantially perpendicular to each other, and the second bent line second node C20b in a substantially vertical state overlaps with the vicinity of the eighth bent line C22b in a substantially vertical state.

また、上記のように、第４折れ線Ｃ４０と第３切込みＫ６０との間隔の長さである第１０長さＨ１０と、第１側面部１０の高さ方向の長さである第１長さＨ１と、第２側面部２０の高さ方向の長さである第２長さＨ２とは略同一の長さであるので、回動後の第２横桟部６４ｂの上側の辺部と、第１側面部１０の上辺部１４ｃと、第２側面部２０の上辺部２４ｃとは、略同一の高さに位置している。つまり、第２横桟部６４ｂの上端の高さを第１側面部１０の上端の高さや第２側面部２０の上端の高さと揃えることができる。   Further, as described above, the tenth length H10 that is the length of the interval between the fourth broken line C40 and the third cut K60, and the first length H1 that is the length of the first side surface portion 10 in the height direction. And the second length H2 that is the length in the height direction of the second side surface portion 20 is substantially the same length, and therefore, the side portion on the upper side of the second horizontal rail portion 64b after the rotation, The upper side portion 14c of the first side surface portion 10 and the upper side portion 24c of the second side surface portion 20 are located at substantially the same height. That is, the height of the upper end of the second horizontal rail portion 64 b can be made equal to the height of the upper end of the first side surface portion 10 and the height of the upper end of the second side surface portion 20.

また、第２横桟部６４ｂの外側の面部（回動前には底面部６０の内側面の一部であった面部）における第１折れ線第２節部Ｃ１０ｂ側の端部と、第２縦桟部１２ｂの内側の面部の上端部とが接着され、第２横桟部６４ｂの外側の面部における第２折れ線第２節部Ｃ２０ｂ側の端部と、第４縦桟部２２ｂの内側の面部の上端部とが接着されている。なお、第２縦桟部１２ｂの内側の面と第４側面部４０の外側の面とを接着するとともに、第４縦桟部２２ｂの内側の面と第４側面部４０の外側の面とを接着するようにしてもよい。   In addition, an end portion on the first broken line second joint portion C10b side in an outer surface portion (a surface portion that was a part of the inner surface of the bottom surface portion 60 before the rotation) of the second horizontal rail portion 64b, and a second vertical length The upper end portion of the inner surface portion of the crosspiece portion 12b is bonded, the end portion on the second broken line second node portion C20b side in the outer surface portion of the second horizontal crosspiece portion 64b, and the inner surface portion of the fourth vertical crosspiece portion 22b. Is bonded to the upper end. The inner surface of the second vertical rail portion 12b and the outer surface of the fourth side surface portion 40 are bonded, and the inner surface of the fourth vertical rail portion 22b and the outer surface of the fourth side surface portion 40 are bonded together. You may make it adhere | attach.

なお、上記のように、支持部１６ｂの回動基端である第１０折れ線Ｃ６０ｂは、第２仮想線上に位置している。この第２仮想線とは、上記の第１折れ線方向線と、第６折れ線Ｃ１２ｂ上の２点を通って第６折れ線Ｃ１２ｂの長さ方向に延びる直線である第６折れ線方向線との交点の近傍を通り、第１折れ線Ｃ１０の中点側にて、第１折れ線方向線に対し略４５度の角度をなす直線である。   As described above, the tenth broken line C60b which is the rotation base end of the support portion 16b is located on the second imaginary line. The second imaginary line is the intersection of the first broken line direction line and the sixth broken line direction line which is a straight line extending in the length direction of the sixth broken line C12b through two points on the sixth folded line C12b. It is a straight line that passes through the vicinity and forms an angle of approximately 45 degrees with respect to the first broken line direction line on the middle point side of the first broken line C10.

また、第１折れ線方向線と第６折れ線方向線とは、略９０度の角度をなし、また、組み立てた状態では、第２縦桟部１２ｂは、底面部６０に対し略垂直である。   Further, the first broken line direction line and the sixth broken line direction line form an angle of approximately 90 degrees, and the second vertical rail portion 12 b is substantially perpendicular to the bottom surface portion 60 in the assembled state.

よって、第１０折れ線Ｃ６０ｂを軸とし、支持部１６ｂを第２縦桟部１２ｂの上端部側へ略１８０度回動させれば、第１折れ線方向線上の線分である第１折れ線第２節部Ｃ１０ｂは、第６折れ線Ｃ１２ｂに対し平行となる。   Therefore, if the support portion 16b is rotated approximately 180 degrees toward the upper end side of the second vertical beam portion 12b with the tenth broken line C60b as an axis, the first broken line second section which is a line segment on the first broken line direction line. The part C10b is parallel to the sixth broken line C12b.

また、支持部２６ｂａの回動基端である第１２折れ線Ｃ７０ｂは、第４仮想線上に位置している。この第４仮想線とは、上記の第２折れ線方向線と、第８折れ線Ｃ２２ｂ上の２点を通って第８折れ線Ｃ２２ｂの長さ方向に延びる直線である第８折れ線方向線との交点の近傍を通り、第２折れ線Ｃ２０の中点側にて、第２折れ線方向線に対し略４５度の角度をなす直線である。   Further, the twelfth broken line C70b that is the rotation base end of the support portion 26ba is located on the fourth imaginary line. The fourth imaginary line is the intersection of the second broken line direction line and the eighth broken line direction line that is a straight line extending in the length direction of the eighth broken line C22b through two points on the eighth folded line C22b. It is a straight line that passes through the vicinity and forms an angle of about 45 degrees with respect to the second broken line direction line on the middle point side of the second broken line C20.

また、第２折れ線方向線と第８折れ線方向線とは、略９０度の角度をなし、また、組み立てた状態では、第４縦桟部２２ｂは、底面部６０に対し略垂直である。   Further, the second broken line direction line and the eighth broken line direction line form an angle of approximately 90 degrees, and the fourth vertical rail portion 22b is substantially perpendicular to the bottom surface portion 60 in the assembled state.

よって、第１２折れ線Ｃ７０ｂを軸とし、支持部２６ｂを第４縦桟部２２ｂの上端部側へ略１８０度回動させれば、第２折れ線方向線上の線分である第２折れ線第２節部Ｃ１０ｂは、第８折れ線Ｃ２２ｂに対し平行となる。   Therefore, if the support portion 26b is rotated by about 180 degrees toward the upper end side of the fourth vertical rail portion 22b with the twelfth broken line C70b as an axis, the second broken line second section which is a line segment on the second broken line direction line. The part C10b is parallel to the eighth polygonal line C22b.

そして、第２横桟部６４ｂは、第２仮想線と第１折れ線方向線との交点と、第４仮想線と第２折れ線方向線との交点とを結ぶ線分を軸とし、ブランク状態における元の位置（第２底面構成部６６ｂと第３底面構成部６６ｃとの間の位置）から、第４側面部４０側へ９０度回動する。   And the 2nd horizontal crosspiece 64b makes the axis | shaft the line segment which connects the intersection of a 2nd virtual line and a 1st broken line direction line, and the intersection of a 4th virtual line and a 2nd broken line direction line, in a blank state From the original position (position between the second bottom surface constituting portion 66b and the third bottom surface constituting portion 66c), it is turned 90 degrees toward the fourth side surface portion 40 side.

この第２仮想線と第１折れ線方向線との交点の位置と、第４仮想線と第２折れ線方向線との交点の位置については、ブランク形成に使用される紙材の厚み、抗折強度等の曲げ加工の容易性に影響を及ぼす特性を考慮し決定する必要があり、上記の第１横桟部６４ａの場合と同様の理由により、第２仮想線と第１折れ線方向線との交点の位置については、第１折れ線方向線と第６折れ線方向線との交点の近傍内にて適宜決定する必要があり、第４仮想線と第２折れ線方向線との交点の位置については、第２折れ線方向線と第８折れ線方向線との交点の近傍内にて適宜決定する必要がある。   About the position of the intersection of this 2nd imaginary line and the 1st broken line direction line, and the position of the intersection of the 4th imaginary line and the 2nd broken line direction line, the thickness of the paper material used for blank formation, and the bending strength It is necessary to determine in consideration of characteristics that affect the ease of bending, such as the above. For the same reason as in the case of the first horizontal beam portion 64a, the intersection of the second imaginary line and the first broken line direction line Must be determined as appropriate within the vicinity of the intersection of the first polygonal line direction line and the sixth polygonal line direction line. It is necessary to determine appropriately within the vicinity of the intersection of the 2nd line direction line and the 8th line direction line.

例えば、紙材が薄く抗折強度が低い場合は、第２仮想線と第１折れ線方向線との交点の位置を、第１折れ線方向線と第４折れ線方向線との交点の位置に一致させ（つまり、第２仮想線が、第１折れ線方向線と第４折れ線方向線との交点を通る）、第４仮想線と第２折れ線方向線との交点の位置を、第２折れ線方向線と第４折れ線方向線との交点の位置に一致させればよい（つまり、第４仮想線が、第２折れ線方向線と第４折れ線方向線との交点を通る）。   For example, when the paper material is thin and the bending strength is low, the position of the intersection of the second imaginary line and the first broken line direction line is made to coincide with the position of the intersection of the first broken line direction line and the fourth broken line direction line. (That is, the second virtual line passes through the intersection of the first broken line direction line and the fourth broken line direction line), and the position of the intersection of the fourth virtual line and the second broken line direction line is defined as the second broken line direction line. It is only necessary to match the position of the intersection with the fourth broken line direction line (that is, the fourth imaginary line passes through the intersection of the second broken line direction line and the fourth broken line direction line).

なお、図９には、第１側面部１０を折り立てる際、同時に支持部１６ａを反転させる場合の状態が示されているが、各支持部１６ａ、２６ａ、１６ｂ、２６ｂの反転、各横桟部６４ａ、６４ｂの回動については、図示したように、第１側面部１０及び第２側面部２０の折り立てと同時に行ってもよいが、第１側面部１０及び第２側面部２０を折り立てた後に、各支持部１６ａ、２６ａ、１６ｂ、２６ｂの反転させ、各横桟部６４ａ、６４ｂを回動させてもよい。   FIG. 9 shows a state in which the support portion 16a is reversed at the same time when the first side surface portion 10 is folded, but the respective support portions 16a, 26a, 16b, 26b are reversed, The rotation of the portions 64a and 64b may be performed simultaneously with the folding of the first side surface portion 10 and the second side surface portion 20 as illustrated, but the first side surface portion 10 and the second side surface portion 20 are folded. After standing up, each support part 16a, 26a, 16b, 26b may be reversed, and each crosspiece part 64a, 64b may be rotated.

上記のようにして、包装箱５は、図１、図２に示すように、組み立てられた状態となる。   As described above, the packaging box 5 is in an assembled state as shown in FIGS. 1 and 2.

組み立てられた包装箱５においては、通常のトレーと同様に使用し、包装箱内部の収納空間に被収納物を収納して使用する。なお、包装箱５が組み立てられた状態においては、底面部６０には、第１横桟部６４ａと第２横桟部６４ｂの領域に開口が形成され、第１側面部１０には、支持部１６ａ、１６ｂの領域に開口が形成され、第２側面部２０には、支持部２６ａ、２６ｂの領域に開口が形成されるので、被収納物はこれらの開口から脱落しない大きさにする必要がある。なお、包装箱５の内側の面（つまり、５つの面）に沿ってシート状の部材を敷き（例えば、１枚のシート状の部材を敷く）、該シート状の部材の中に被収納物を収納してもよい。   The assembled packaging box 5 is used in the same manner as a normal tray, and the objects to be stored are stored in the storage space inside the packaging box. In the state where the packaging box 5 is assembled, the bottom surface portion 60 is formed with openings in the areas of the first horizontal rail portion 64a and the second horizontal rail portion 64b, and the first side surface portion 10 has a support portion. Openings are formed in the regions 16a and 16b, and openings are formed in the regions of the support portions 26a and 26b in the second side surface portion 20. Therefore, it is necessary to make the contents to be stored so as not to fall out from these openings. is there. In addition, a sheet-like member is laid along the inner surface (that is, five surfaces) of the packaging box 5 (for example, one sheet-like member is laid), and an object to be stored in the sheet-like member. May be stored.

以上のように、本実施例の包装箱５によれば、第３側面部３０と、第３側面部３０の両側端部の一方に立設される第１縦桟部１２ａと、他方に立設される第３縦桟部２２ａと、両縦桟部１２ａ、２２ａの上端部間に架設される第１横桟部６４ａとにより額縁形状の第３側面部３０側を形成できるとともに、第４側面部４０と、第４側面部４０の両側端部の一方に立設される第２縦桟部１２ｂと、他方に立設される第４縦桟部２２ｂと、両縦桟部１２ｂ、２２ｂの上端部間に架設される第２横桟部６４ｂとにより、第３側面部３０に相対する額縁形状の第４側面部４０側を形成できることから、第１側面部１０の高さ方向の長さである第１長さＨ１と第２側面部２０の高さ方向の長さである第２長さＨ２とに比べて、第３側面部３０の高さ方向の長さである第３長さＨ３と第４側面部４０の高さ方向の長さである第６長さＨ６とを短くすることができ、例えば、同一高さの４つ側面部を有する従前の包装箱で、４側面部の高さ方向の長さがＨ１である包装箱に比べて、ブランク形成に要する紙材の正味を削減することができ、包装箱の製造コストを低減することができる。   As described above, according to the packaging box 5 of the present embodiment, the third side surface portion 30, the first vertical rail portion 12 a erected on one of both end portions of the third side surface portion 30, and the other side The frame-shaped third side surface 30 side can be formed by the third vertical beam portion 22a provided and the first horizontal beam portion 64a provided between the upper ends of the vertical beam portions 12a and 22a. The side surface portion 40, the second vertical beam portion 12b erected on one of both end portions of the fourth side surface portion 40, the fourth vertical beam portion 22b erected on the other side, and both the vertical beam portions 12b and 22b Since the frame-shaped fourth side surface portion 40 facing the third side surface portion 30 can be formed by the second horizontal rail portion 64b installed between the upper end portions of the first side surface portion 10, the length of the first side surface portion 10 in the height direction Compared with the first length H1 that is the height and the second length H2 that is the length in the height direction of the second side surface portion 20, the height direction of the third side surface portion 30 The third length H3, which is the length, and the sixth length H6, which is the length in the height direction of the fourth side surface portion 40, can be shortened. For example, a conventional length having four side surfaces having the same height is provided. Compared with a packaging box in which the length in the height direction of the four side surfaces is H1, the net of the paper material required for blank formation can be reduced, and the manufacturing cost of the packaging box can be reduced. it can.

つまり、包装箱５の場合、第１長さＨ１（＝第２長さＨ２）から第３長さＨ３を差し引いた長さに第３側面部３０の横幅方向の長さを掛け算して得られる面積と、第１長さＨ１（＝第２長さＨ２）から第６長さＨ６を差し引いた長さに第４側面部４０の横幅方向の長さを掛け算して得られる面積との合計面積相当分を上記従前包装箱の場合に比べて削減することができる。   That is, in the case of the packaging box 5, it is obtained by multiplying the length obtained by subtracting the third length H <b> 3 from the first length H <b> 1 (= second length H <b> 2) by the length in the width direction of the third side surface portion 30. The total area of the area and the area obtained by multiplying the length obtained by subtracting the sixth length H6 from the first length H1 (= second length H2) by the length in the horizontal width direction of the fourth side surface portion 40 A considerable amount can be reduced compared to the case of the previous packaging box.

また、第３長さＨ３と、第１縦桟部１２ａの横幅方向の長さである第４長さＨ４と、第３縦桟部２２ａの横幅方向の長さである第５長さＨ５と、第６長さＨ６と、第２縦桟部１２ｂの横幅方向の長さである第７長さＨ７と、第４縦桟部２２ｂの横幅方向の長さである第８長さＨ８とが、第１長さＨ１よりも短いので、ブランク形成時に生じる紙材のロスが削減され、特に、第３長さＨ３〜第８長さＨ８が略同一の長さになるように形成されていることにより、ブランク形成時に生じる紙材のロスが削減され、包装箱の製造コストを低減することができる。   Further, the third length H3, the fourth length H4 that is the length of the first vertical beam portion 12a in the horizontal width direction, and the fifth length H5 that is the length of the third vertical beam portion 22a in the horizontal width direction, The sixth length H6, the seventh length H7 which is the length in the horizontal width direction of the second vertical beam portion 12b, and the eighth length H8 which is the length in the horizontal width direction of the fourth vertical beam portion 22b. Since it is shorter than the first length H1, the loss of the paper material that occurs during blank formation is reduced, and in particular, the third length H3 to the eighth length H8 are formed to be substantially the same length. Thereby, the loss of the paper material which arises at the time of blank formation is reduced, and the manufacturing cost of a packaging box can be reduced.

つまり、同一高さの４側面部を有する従前包装箱では、ブランクの全体概形（概略輪郭）が略十文字形となるため、ブランク形成用の紙材中にブランク形成領域を無駄なく詰めて並べることが困難であるが、包装箱５では、ブランクの全体概形が略方形状となることから、側面部の高さ方向の長さが長く、深さが深い包装箱であっても、紙材中にブランク形成領域を効率良く並べて、非形成領域が占める面積が削減される。   That is, in the conventional packaging box having four side portions of the same height, the blank outline outline (rough outline) is substantially cross-shaped, so the blank forming area is packed and arranged in the blank forming paper material without waste. However, in the packaging box 5, since the overall outline of the blank is substantially rectangular, the length of the side surface in the height direction is long, and even if the packaging box has a deep depth, The blank forming region is efficiently arranged in the material, and the area occupied by the non-forming region is reduced.

また、各横桟部６４ａ、６４ｂと、各支持部１６ａ、２６ａ、１６ｂ、２６ｂとが一体で、支各横桟部６４ａ、６４ｂが、各支持部１６ａ、２６ａ、１６ｂ、２６ｂにより支持されていることにより、包装箱５の強度維持を図ることができ、特に、包装箱５の第３側面部３０側の側面と第４側面部４０側の側面の強度維持を図ることができる。   Further, the horizontal beam portions 64a and 64b and the support portions 16a, 26a, 16b and 26b are integrated, and the support horizontal beam portions 64a and 64b are supported by the support portions 16a, 26a, 16b and 26b. Therefore, the strength of the packaging box 5 can be maintained, and in particular, the strength of the side surface of the packaging box 5 on the third side surface portion 30 side and the side surface of the fourth side surface portion 40 side can be maintained.

つまり、額縁形状の側面部構造を形成するに当たり、例えば、包装箱本体部とは別体の横桟部で、横長の長方形状に形成された横桟部の一方の側端部を一方の縦桟部の上端部に接着し、横桟部の他方の側端部を他方の縦桟部の上端部に接着して、両縦桟部間に横桟部を架設した場合、このような包装箱本体部と横桟部とから構成された包装箱では、包装箱を取り扱う際、横桟部が内外から押圧されたり、横桟部の上側の辺部に手を掛け引っ張ったりされることで、接着部が荷重に耐えられずに剥離し易く、従前の包装箱に比べて、包装箱が損壊し易い。   In other words, when forming a frame-shaped side surface structure, for example, a horizontal rail portion separate from the packaging box main body portion, and one side end portion of the horizontal rail portion formed in a horizontally long rectangular shape is If the horizontal beam is bonded to the upper end of the beam, the other side edge of the horizontal beam is bonded to the upper end of the other vertical beam, and the horizontal beam is installed between both vertical beams, such packaging In a packaging box composed of a box body and a horizontal rail, when handling the packaging box, the horizontal rail is pressed from inside or outside, or the hand is pulled by the upper side of the horizontal rail. The bonded portion cannot withstand the load and easily peels off, and the packaging box is easily damaged as compared with the conventional packaging box.

つまり、別体の横桟部は、それ自体だけでは、底面部の辺部上方に留まることができないものであるから、横桟部に加えられた様々な向きの荷重の殆どを接着剤により受け止めなければならないが、これに対し、包装箱５の場合、第１横桟部６４ａは、どこかに接着されていなくても、支持部１６ａと支持部２６ａとにより支持されて、第３側面部３０の上方にて留まっていることが可能であり、つまり、第１横桟部６４ａは、支持部１６ａと支持部２６ａとにより束縛され、その自由度が限定されていることから、第１横桟部６４ａに加えられた様々な向きの荷重のうち幾分かは、接着剤ではなく、支持部１６ａと支持部２６ａとにより受け止め、接着剤にかかる負担、疲労が少ないため、従前の包装箱と比較しても、遜色のない接着耐久性を示す。   In other words, since the separate crosspiece itself cannot stay above the side part of the bottom part by itself, most of the loads in various directions applied to the horizontal crosspiece are received by the adhesive. On the other hand, in the case of the packaging box 5, the first horizontal rail portion 64 a is supported by the support portion 16 a and the support portion 26 a even if it is not bonded somewhere, and the third side surface portion. 30. That is, the first horizontal crosspiece 64a is constrained by the support portion 16a and the support portion 26a, and the degree of freedom thereof is limited. Some of the loads in various directions applied to the crosspiece 64a are received by the support 16a and the support 26a, not the adhesive, and less burden and fatigue on the adhesive. Adhesive durability comparable to that of It is shown.

特に、第１横桟部６４ａの外側から内側へ荷重が加わった場合、支持部１６ａと支持部２６ａとが、方杖（ほうづえ 築で補強のために、水平材と、これに交差する垂直材とによって生ずる鉛直面の入隅部分を斜めに結ぶ部材）と同様の作用により、第１横桟部６４ａを強固に支えるため、頑強であるだけでなく、荷重の殆どを支持部１６ａと支持部２６ａとで受け止め、接着部に負担をかけない。   In particular, when a load is applied from the outer side to the inner side of the first horizontal beam portion 64a, the support portion 16a and the support portion 26a are formed into a cane (a horizontal member for reinforcement in the construction of the rod and a vertical crossing this. In order to firmly support the first crosspiece 64a by an action similar to that of a member that obliquely connects the corners of the vertical plane generated by the material, it is not only robust, but also supports most of the load with the support 16a. It catches with the part 26a, and does not put a burden on an adhesion part.

また、第４側面部４０側についても、第２横桟部６４ｂが、支持部１６ｂと支持部２６ｂとにより、支持されていることにより、第３側面部３０側と同様の理由で、第２横桟部６４ｂの外側から内側へ荷重に対し頑強で、第２横桟部６４ｂと各縦桟部１２ｂ、２２ｂとの接着強度が維持される。   Further, the second side rail portion 64b is also supported by the support portion 16b and the support portion 26b on the fourth side surface portion 40 side, for the same reason as the third side surface portion 30 side. Strong against load from the outside to the inside of the horizontal beam portion 64b, the adhesive strength between the second horizontal beam portion 64b and the vertical beam portions 12b and 22b is maintained.
