Description

包装箱のブランクシート及びその包装箱Blank sheet of packaging box and its packaging box
　本発明は包装箱のブランクシートに関する。より詳しくは、自動封緘装置に対応した包装箱のブランクシートであって、当該ブランクシートからなる包装箱は樹脂製の結束バンドで結束しても結束バンドが食い込みにくい包装箱に関する。 The present invention relates to a blank sheet of a packaging box. More specifically, the present invention relates to a blank sheet of a packaging box compatible with an automatic sealing device, wherein the packaging box made of the blank sheet is a packaging box in which the binding band does not easily bite even when bound by a resin binding band.
　商品を輸送する際に、耐衝撃性、防汚性及び積載や運搬のしやすさ等の観点から、段ボール箱に商品を詰めて輸送することが一般的に行われている。また、複数の段ボール箱を一つにまとめて輸送する場合、段ボール箱がバラバラにならないように樹脂製の結束バンドで結束することも広く行われている。 When transporting products, it is common practice to pack the products in cardboard boxes from the viewpoints of impact resistance, stain resistance, and ease of loading and transportation. Further, when a plurality of corrugated cardboard boxes are transported together, it is widely practiced to bind the corrugated cardboard boxes with a resin binding band so that the corrugated cardboard boxes do not fall apart.
　段ボール箱を結束バンドで結束する場合、結束バンドが段ボール箱の角部に食い込んでエッジ切れが起こってしまうことがある。特に軽量化した段ボール箱は結束バンドが食い込みやすく、湿気の高い環境下では段ボール箱の剛性が弱まるため、その傾向が強い。段ボール箱に結束バンドが食い込んでしまったりエッジ切れを起こしてしまったりすると、段ボール箱内の商品に変形などの影響が出たり、虫や水が段ボール箱内に入り込みやすくなったりするといった問題が発生しやすくなる。 When binding a cardboard box with a binding band, the binding band may bite into the corner of the cardboard box and cause edge breakage. In particular, lightweight cardboard boxes tend to be easily bitten by cable ties, and the rigidity of cardboard boxes weakens in a humid environment, which is a strong tendency. If the cable tie bites into the cardboard box or the edges are cut off, the products inside the cardboard box may be deformed, or insects or water may easily enter the cardboard box. It will be easier to do.
　そこで、結束バンドが段ボール箱に食い込むことを防止するために、段ボール箱の角部に面取り部を設ける方法が提案されている。例えば、特許文献１には、エッジ切れ防止加工部として、基本折目線を挟んで一方に段潰部分、他方に離間折目線が形成された段ボール箱が開示されている。この段ボール箱は、バンドに張力が作用して稜部が締め付けられると、稜部の段ボールが二重に折れて傾斜面が生じ、巻き締まり強度が向上するとともに、バンドの段ボールへの食い込みが抑制される構造となっている。 Therefore, in order to prevent the binding band from biting into the cardboard box, a method of providing a chamfered portion at the corner of the cardboard box has been proposed. For example, Patent Document 1 discloses a corrugated cardboard box in which a stepped portion is formed on one side and a separated crease line is formed on the other side of the basic crease line as an edge breakage prevention processing portion. In this cardboard box, when tension acts on the band and the ridge is tightened, the cardboard at the ridge is double-folded to form an inclined surface, which improves the winding strength and suppresses the band from biting into the cardboard. It has a structure to be used.
特許６１１２９９２号公報Japanese Patent No. 6112992
　ところで、特許文献１に記載の段ボール箱は、いわゆる、ミカン箱（ＪＩＳ　Ｚ　１５０７　０２（溝切形）に基づく段ボール製包装箱）と呼ばれるものである。溝切形の段ボール箱はある程度の容量があることから、異なるサイズの物などをまとめて一つの箱内に収納する際に便利である。この溝切形の段ボール箱は、まず底面を封緘し、続いて段ボール内部に商品を入れた後に天面部を封緘して用いるのが一般的である。そして、溝切形の段ボール箱は人の手による組み立てや封緘が多いことから、フラップの折り畳み等のライン適正についてはさほど厳密性を求められていない。 By the way, the corrugated cardboard box described in Patent Document 1 is a so-called mandarin orange box (a corrugated cardboard packaging box based on JIS Z 1507 02 (grooving type)). Since the grooved cardboard box has a certain capacity, it is convenient for storing items of different sizes together in one box. In this grooved cardboard box, it is common to first seal the bottom surface, then put the product inside the cardboard, and then seal the top surface. And since grooved corrugated cardboard boxes are often assembled and sealed by human hands, there is not much demand for strictness regarding line suitability such as folding flaps.
　一方、段ボール製包装箱には上記溝切形以外に、ＪＩＳ　Ｚ　１５０７　０３（テレスコープ形），０４（組立形），０５（差し込み形），０６（ブリス形），０７（糊付け簡易組立形）なども存在する。特に、同一形状の複数の商品を梱包する際には、ブランクシート上に複数の商品を置いた状態で製函できる組立形が多く用いられている。ここで、組立形の段ボールの製函は自動封緘装置（以下、「オートケーサー」という。）で行われる。オートケーサーで製函する場合、ダンボール箱には厳密なライン適正が求められる。そのため、組立形の段ボール箱に特許文献１のような面取り部を設けてしまうと、面取り部を設けなかった場合に比べて、製函不良の発生頻度が増加する恐れがある。 On the other hand, in addition to the above grooving type, the corrugated cardboard packaging box has JIS Z 1507 03 (telescope type), 04 (assembly type), 05 (insertion type), 06 (bliss type), 07 (glue simple assembly type). And so on. In particular, when packing a plurality of products having the same shape, an assembled type that can produce a box with the plurality of products placed on a blank sheet is often used. Here, the boxing of the assembled corrugated cardboard is performed by an automatic sealing device (hereinafter, referred to as "autocaser"). When making boxes with an autocaser, strict line suitability is required for cardboard boxes. Therefore, if a chamfered portion as in Patent Document 1 is provided in the assembled corrugated cardboard box, the frequency of box-making defects may increase as compared with the case where the chamfered portion is not provided.
　本発明は上記問題点に鑑みてなされたものである。すなわち、結束バンドが包装箱に食い込むことを防ぎ、かつ、オートケーサーでの製函に適した包装箱のブランクシート及びその包装箱を提供することを目的とする。本発明者はオートケーサーでの製函時には補助罫線に力が加わりにくく、バンド締結時には補助罫線に力が加わるような主罫線及び補助罫線の設け方について検討を起こった。そして、補助罫線の設け方によって、上記課題を解決できることを新たに見出し、本発明を完成するに至った。 The present invention has been made in view of the above problems. That is, it is an object of the present invention to provide a blank sheet of a packaging box and the packaging box thereof, which prevents the binding band from biting into the packaging box and is suitable for box making with an autocaser. The present inventor has studied how to provide the main ruled line and the auxiliary ruled line so that the force is not easily applied to the auxiliary ruled line when the box is manufactured by the autocaser and the force is applied to the auxiliary ruled line when the band is fastened. Then, they have newly found that the above problem can be solved by the method of providing the auxiliary ruled line, and have completed the present invention.
　上記課題解決のため、本発明は、主罫線を介して連接された２方向の壁面板がなす綾部に、物流用バンドによるエッジ切れを防止するための面取り部を設けた包装箱のブランクシートにおいて、前記面取り部は、主罫線を挟んで鏡対象に設けられた補助罫線によって形作られ、ブランクシートの内面側には前記主罫線及び前記補助罫線が設けられ、ブランクシートの外面側には前記主罫線が設けられている、ブランクシートを提供する。 In order to solve the above problems, the present invention relates to a blank sheet of a packaging box in which a chamfered portion for preventing edge breakage due to a distribution band is provided on a twill portion formed by wall plates in two directions connected via a main ruled line. The chamfered portion is formed by an auxiliary ruled line provided on the mirror object with the main ruled line interposed therebetween, the main ruled line and the auxiliary ruled line are provided on the inner surface side of the blank sheet, and the main ruled line is provided on the outer surface side of the blank sheet. Provided is a blank sheet provided with a ruled line.
　かかる構成によれば、ブランクシートの内面側にのみ補助罫線が設けられているため、オートケーサーで製函する際に製函不良が起こりにくい。また、ブランクシートの内外両面に主罫線が設けられているため、製函しやすい。 According to this configuration, since the auxiliary ruled line is provided only on the inner surface side of the blank sheet, box making failure is unlikely to occur when the box is made by the autocaser. In addition, since the main ruled lines are provided on both the inner and outer sides of the blank sheet, it is easy to make a box.
　さらに、上記構成においては、主ブランクシートの外面側において、前記補助罫線と対応する位置にミシン目が設けられていることが好ましい。また、補助罫線には、さらにミシン目が付与されていることが好ましい。さらに、主罫線と補助罫線は段潰しとなっており、包装箱内面側の主罫線は包装箱外面側の主罫線よりも深く加工されていることが好ましい。 Further, in the above configuration, it is preferable that a perforation is provided at a position corresponding to the auxiliary ruled line on the outer surface side of the main blank sheet. Further, it is preferable that the auxiliary ruled line is further perforated. Further, the main ruled line and the auxiliary ruled line are step-crushed, and it is preferable that the main ruled line on the inner surface side of the packaging box is deeper than the main ruled line on the outer surface side of the packaging box.
　かかる構成によれば、ミシン目を設けることで、締結用バンドで締結した際に面取り部が形成されやすくなる。また、段潰し構造の深さに差を設けることで、製函のしやすさを向上させることができる。 According to such a configuration, by providing perforations, a chamfered portion is easily formed when fastening with a fastening band. Further, by providing a difference in the depth of the step crushing structure, the ease of box making can be improved.

The formation direction of the ruled line in the present embodiment is along each edge, but the formation direction is not limited to this, and the ruled line may be formed in any direction.
（補助罫線４０について）
　本実施形態における補助罫線４０は、結束バンドによる張力が包装箱１０の角部にかかった際に、後述する面取り部５０の形成を誘導するための役割を担うものである。すなわち、補助罫線４０によって囲われた箇所が、後述する面取り部５０として機能する。図２に示すように、本実施形態においては、裏ライナ側からのみ中芯に向かって押し潰す段潰し加工によって補助罫線４０が形成されている。なお、補助罫線４０における段潰し加工は、主罫線Ｌ１～Ｌ８における段潰し加工よりも浅く押し潰されていることが好ましい。 (About auxiliary ruled line 40)
The auxiliary ruled line 40 in the present embodiment plays a role of inducing the formation of the chamfered portion 50, which will be described later, when the tension due to the binding band is applied to the corner portion of the packaging box 10. That is, the portion surrounded by the auxiliary ruled line 40 functions as the chamfered portion 50 described later. As shown in FIG. 2, in the present embodiment, the auxiliary ruled line 40 is formed by the step crushing process of crushing toward the core only from the back liner side. It is preferable that the step crushing process on the auxiliary ruled line 40 is shallower than the step crushing process on the main ruled lines L1 to L8.
　本実施形態において、補助罫線４０は、主罫線Ｌ１～８を挟んで鏡対象となるように形成されている。より詳しくは、補助罫線４０は、主罫線を挟んで主罫線と平行に設けられた一対の辺４１と、辺４１となす角度が鈍角となるように、それぞれの辺４１の両末端から主罫線に向かって設けられた辺４２で構成されている。辺４２の末端のうち、辺４１と接していない末端は、辺４２の末端同士が接することで、閉じた空間を形成している。なお、本実施形態において、補助罫線によって形成される形状が６角形であるが、６以上の偶数角からなる多角形状であれば特に制限はされない。 In the present embodiment, the auxiliary ruled line 40 is formed so as to be a mirror object with the main ruled lines L1 to 8 interposed therebetween. More specifically, the auxiliary ruled line 40 has a pair of sides 41 provided parallel to the main ruled line with the main ruled line in between, and a main ruled line from both ends of each side 41 so that the angle formed with the side 41 is an obtuse angle. It is composed of sides 42 provided toward. Of the ends of the side 42, the ends that are not in contact with the side 41 form a closed space because the ends of the side 42 are in contact with each other. In the present embodiment, the shape formed by the auxiliary ruled line is a hexagon, but there is no particular limitation as long as it is a polygonal shape composed of even-numbered angles of 6 or more.
　（面取り部５０について）
　図２を用いて、第１縁辺Ｌ１、第２縁辺Ｌ２、及び、一対の第３縁辺Ｌ３に設けられた面取り部について説明する。ここで、第８縁辺Ｌ８、第５縁辺Ｌ５、及び、一対の第７縁辺Ｌ７における面取り部は、それぞれ、第１縁辺Ｌ１、第２縁辺Ｌ２、及び、一対の第３縁辺Ｌ３における面取り部と同様の形態であることから、説明は省略する。 (About chamfering part 50)
A chamfered portion provided on the first edge L1, the second edge L2, and the pair of third edge L3 will be described with reference to FIG. Here, the chamfered portions at the eighth edge L8, the fifth edge L5, and the pair of seventh edge L7 are the chamfered portions at the first edge L1, the second edge L2, and the pair of third edge L3, respectively. Since it has the same form, the description thereof will be omitted.
　面取り部５０は、樹脂バンドで締結した際に包装箱１０の破損を防ぐためのものである。詳細については後述するが、包装箱１０の角が潰れて面取り部５０が形成されることで、食い込みを防ぐことができる。面取り部５０は、補助罫線４０で形作られた多角形状が該当する。なお、本実施形態においては、第１面部の４つの縁辺（主罫線）Ｌ１～３には、各主罫線の中央に面取り部５０が設けられている。 The chamfered portion 50 is for preventing damage to the packaging box 10 when it is fastened with a resin band. Although the details will be described later, the corners of the packaging box 10 are crushed to form the chamfered portion 50, so that biting can be prevented. The chamfered portion 50 corresponds to a polygonal shape formed by the auxiliary ruled line 40. In the present embodiment, chamfered portions 50 are provided at the center of each main ruled line on the four edge edges (main ruled lines) L1 to 3 of the first surface portion.
（ミシン目６０について）
　本実施形態においては、製函に影響を与えず、かつ、締結バンドにより張力がかかった際に面取り部５０が形成されやすくすることを目的として、裏ライナに対してさらにミシン目６０を設けてもよい。ミシン目６０を設ける位置としては、段潰し加工が施された補助罫線４０上にミシン目６０を設けることが好ましい。また、裏ライナ以外に表ライナにミシン目６０を設けてもよい。表ライナに設けるミシン目６０の位置としては、裏ライナに設けられた補助罫線４０と対応する位置に設けることが好ましい。 (About perforation 60)

May be good. As the position where the perforation 60 is provided, it is preferable to provide the perforation 60 on the auxiliary ruled line 40 which has been subjected to the step crushing process. In addition to the back liner, the front liner may be provided with perforations 60. The position of the perforation 60 provided on the front liner is preferably a position corresponding to the auxiliary ruled line 40 provided on the back liner.
　＜包装箱の製函について＞
　本実施形態におけるブランクシート１０Ｂから包装箱１０を組み立てる一例について説明する。まず、ブランクシート１０Ｂを、裏ライナが上側に位置するように配置する。次に、第１面部１１上に、収容する物品を載置する。第１面部１１を中心として、第１主罫線Ｌ１及び第２主罫線Ｌ２を介して、第２面部１２及び第３面部１３を折り曲げる。そして、一対の第４主罫線Ｌ４及び一対の第６主罫線Ｌ６を介して、一対の第１内フラップ部２１及び一対の第２内フラップ部２３を折り曲げる。続いて、第１内フラップ部２１及び第２内フラップ部２３の上に重なるように、一対の第３主罫線Ｌ３を介して、一対の第１外フラップ部３１を折り曲げるとともに、第１内フラップ部２１及び第２内フラップ部２３に接着する。さらに、第５主罫線Ｌ５を介して、第４面部１４を折り曲げて、第１面部１１と対向させた状態とし、続いて、第１内フラップ部２１及び第２内フラップ部２３の上に重なるように、一対の第７主罫線Ｌ７を介して、一対の第２外フラップ部３３を折り曲げるとともに、第１内フラップ部２１及び第２内フラップ部２３に接着する。最後に、第２面部１２の上に重なるように、第８主罫線Ｌ８を介して、第５面部１５を折り曲げるとともに、第２面部１２に接着することで、図１に示した包装箱１０が組み立てられる。本実施形態における接着は、例えば、熱溶融樹脂等の接着剤によって貼着（ホットメルト）することにより行われる。また、本実施形態における接着剤の塗布は、各接着部位に対して適宜のタイミングで行うことができる。この組み立てにより、第１面部１１を底面部、第４面部１４を天面部、第２面部１２、第５面部１５及び第３面部１３を長さ面部とし、一対の第１内フラップ部２１、一対の第２内フラップ部２３、一対の第１外フラップ部３１及び一対の第２外フラップ部３３を幅面部とする包装箱１０が形成される。ここで、本発明によれば主罫線Ｌ１～８は段潰し加工となっているため、折り曲げやすくなっている。また、補助罫線４０は裏面ライナにしか設けられていないため、製函不良が起こりにくい。製函時、補助罫線４０が折れ曲がらないのは、主罫線Ｌ１～８が表ライナと裏ライナの両側に設けられているため、補助罫線４０よりも折れ曲がりやすくなっているためである。すなわち、主罫線Ｌ１～８が折れ曲がりやすいため、製函にかかる力が主罫線Ｌ１～８に集まりやすく、補助罫線４０には伝播しないためであると考えられる。 <About making packaging boxes>
An example of assembling the packaging box 10 from the blank sheet 10B in the present embodiment will be described. First, the blank sheet 10B is arranged so that the back liner is located on the upper side. Next, the article to be accommodated is placed on the first surface portion 11. The second surface portion 12 and the third surface portion 13 are bent around the first surface portion 11 via the first main ruled line L1 and the second main ruled line L2. Then, the pair of first inner flap portions 21 and the pair of second inner flap portions 23 are bent via the pair of fourth main ruled lines L4 and the pair of sixth main ruled lines L6. Subsequently, the pair of first outer flap portions 31 are bent via the pair of third main ruled lines L3 so as to overlap the first inner flap portion 21 and the second inner flap portion 23, and the first inner flap portion 31 is bent. It adheres to the portion 21 and the second inner flap portion 23. Further, the fourth surface portion 14 is bent so as to face the first surface portion 11 via the fifth main ruled line L5, and subsequently overlaps the first inner flap portion 21 and the second inner flap portion 23. As described above, the pair of the second outer flap portions 33 are bent and adhered to the first inner flap portion 21 and the second inner flap portion 23 via the pair of the seventh main ruled lines L7. Finally, the packaging box 10 shown in FIG. 1 is formed by bending the fifth surface portion 15 via the eighth main ruled line L8 and adhering it to the second surface portion 12 so as to overlap the second surface portion 12. Assembled. Adhesion in the present embodiment is performed by, for example, sticking (hot melting) with an adhesive such as a heat-melted resin. In addition, the adhesive in the present embodiment can be applied to each adhesive portion at an appropriate timing. By this assembly, the first surface portion 11 is a bottom surface portion, the fourth surface portion 14 is a top surface portion, the second surface portion 12, the fifth surface portion 15 and the third surface portion 13 are length surface portions, and a pair of first inner flap portions 21 and a pair. A packaging box 10 having a second inner flap portion 23, a pair of first outer flap portions 31 and a pair of second outer flap portions 33 as width surface portions is formed. Here, according to the present invention, since the main ruled lines L1 to L8 are step-crushed, they are easily bent. Further, since the auxiliary ruled line 40 is provided only on the back surface liner, box making failure is unlikely to occur. The reason why the auxiliary ruled line 40 does not bend during box making is that the main ruled lines L1 to L8 are provided on both sides of the front liner and the back liner, so that the auxiliary ruled line 40 is more easily bent than the auxiliary ruled line 40. That is, it is considered that the main ruled lines L1 to 8 are easily bent, so that the force applied to the box making is likely to be concentrated on the main ruled lines L1 to 8 and does not propagate to the auxiliary ruled lines 40.
　＜面取り部５０形成機序について＞
　面取り部５０は次のようにして形成される。図１に示すように、本実施形態にかかる製函したばかりの包装箱１０の表ライナ（外側）には面取り部５０の形状に合わせたミシン目６０はあるものの、面取り部５０はいまだ形成されていない。図４は、製函した包装箱１０を上下方向（図１参照）に複数（ここでは３個）積み上げたものである。積み上げた包装箱１０に対して、幅方向及び長さ方向（図１における前後方向及び左右方向）に締結バンドを掛ける（図５参照）。包装箱１０に掛けられた締結バンドはバンドの締め上げとともに、最上段及び最下段の包装箱１０の角部に当接する。包装箱１０の角部に当接したバンドは、締め上げる力を包装箱１０の内部に向かって働かせる。 <Chamfering part 50 forming mechanism>
The chamfered portion 50 is formed as follows. As shown in FIG. 1, although the front liner (outside) of the packaging box 10 just made according to the present embodiment has a perforation 60 that matches the shape of the chamfered portion 50, the chamfered portion 50 is still formed. Not. FIG. 4 shows a plurality (here, three) of the packaged packaging boxes 10 stacked in the vertical direction (see FIG. 1). The fastening bands are hung on the stacked packaging boxes 10 in the width direction and the length direction (front-rear direction and left-right direction in FIG. 1) (see FIG. 5). The fastening band hung on the packaging box 10 comes into contact with the corners of the top and bottom packaging boxes 10 as the band is tightened. The band in contact with the corners of the packaging box 10 exerts a tightening force toward the inside of the packaging box 10.
　このとき、図６（ａ）に示すように、包装箱１０は角部に集中した張力を分散させようとする。角部にかかった張力は、図６（ａ）の実線白抜きの矢印のように包装箱１０の面部を伝う。そうして伝った張力は補助罫線４０にも伝達される。補助罫線４０である段潰し部は裏面ライナが中芯に向かって押しつぶされているため、角部から伝わってきた力によって折れ曲がりやすくなっている。さらに、表面ライナや補助罫線４０にミシン目６０が設けられていると、ミシン目６０に対して応力が集中するため、より折れ曲がりやすくなる。これにより、補助罫線４０が折れ曲がる。補助罫線４０のうちどこか一カ所でも折れ曲がると、面部を伝ってきた力は補助罫線４０を伝って伝播していく。補助罫線４０が折れ曲がると面取り部５０が浮かび上がり、それと同時に角部は図６（ｂ）のように平面に戻る。ここで、面取り部５０が形成されると、当初１つだけだった角部は２つに増える。２つに増えることで、従来１つの角部にかかっていた張力はより分散され、包装箱への食い込みを防ぐことができる。また、面取り部５０が形成されることで締結バンドと段ボール箱との接触面積が増えるため、より強固に締結することができる。さらに、従来の包装箱と異なり、食い込みを起こさず、面が凹むだけで済む。 At this time, as shown in FIG. 6A, the packaging box 10 tries to disperse the tension concentrated on the corners. The tension applied to the corner portion travels along the surface portion of the packaging box 10 as shown by the solid white arrow in FIG. 6 (a). The tension transmitted in this way is also transmitted to the auxiliary ruled line 40. Since the back liner of the step-crushed portion, which is the auxiliary ruled line 40, is crushed toward the center core, the step-crushed portion is easily bent by the force transmitted from the corner portion. Further, when the perforations 60 are provided on the surface liner and the auxiliary ruled line 40, the stress is concentrated on the perforations 60, so that the perforations are more easily bent. As a result, the auxiliary ruled line 40 is bent. If any one of the auxiliary ruled lines 40 is bent, the force transmitted through the surface portion is propagated along the auxiliary ruled lines 40. When the auxiliary ruled line 40 is bent, the chamfered portion 50 emerges, and at the same time, the corner portion returns to a flat surface as shown in FIG. 6 (b). Here, when the chamfered portion 50 is formed, the number of corner portions, which was initially only one, increases to two. By increasing the number to two, the tension applied to one corner is more dispersed, and it is possible to prevent the tension from biting into the packaging box. Further, since the contact area between the fastening band and the cardboard box is increased by forming the chamfered portion 50, the fastening can be performed more firmly. Further, unlike the conventional packaging box, it does not bite and only the surface is dented.
　これに対して、従来の包装箱は、図７に示すように、角部に集中した張力が包装箱の面部を伝っても、応力を集中させる箇所がない。その結果、角部に集中した張力が限界を超えると、バンドの食い込みによるエッジ切れが起こる。 On the other hand, in the conventional packaging box, as shown in FIG. 7, even if the tension concentrated on the corners is transmitted through the surface portion of the packaging box, there is no place where the stress is concentrated. As a result, when the tension concentrated on the corners exceeds the limit, edge breakage occurs due to the biting of the band.
　以下、具体的構成を例に本発明をより詳細に説明する。 Hereinafter, the present invention will be described in more detail by taking a specific configuration as an example.
　表〇に記載の条件に基づいて、包装箱ブランクシートを作成した。当該ブランクシート上に容器入り即席食品を載せ、オートケーサーで製函した。各実施例・比較例にかかる包装箱は３箱ずつ製函した。得られた包装箱は次の条件下で試験を行った。 A packaging box blank sheet was created based on the conditions shown in Table 〇. Instant food in a container was placed on the blank sheet and boxed with an autocaser. Three packaging boxes were manufactured for each of the Examples and Comparative Examples. The obtained packaging box was tested under the following conditions.

（製函試験）
　表１に基づくブランクシートをオートケーサーで製函し、製函不良を製函適正という観点から確認した。製函適正の基準は次の通りである。
　○：現状設備を用いて、通常ブランクシートと同様に製函可能である。
　△：現状設定ではロスが発生するが、軽微な調整で製函可能である。
　×：大幅な設備改造が必要となり、通常のブランクシートを製函する場合との併用が難しい。 (Box making test)
A blank sheet based on Table 1 was box-made with an autocaser, and box-making defects were confirmed from the viewpoint of box-making suitability. The criteria for proper box making are as follows.
◯: It is possible to make a box in the same way as a normal blank sheet using the current equipment.
Δ: Loss occurs in the current setting, but it is possible to make a box with minor adjustments.
×: Significant equipment modification is required, and it is difficult to use it together with the case of making a normal blank sheet.
（締結試験）
　締結試験は容器入り即席食品が入った包装箱を図４のように３段重ね、締結バンドを幅方向及び長さ方向に掛けた。締結バンドが撓まず、面に対して密着するように締結バンドを締め上げた。このとき、包装箱の角に締結バンドが食い込んでいたり、エッジ切れが起こっていたりしないか確認を行った。判断基準は次の通りである。結果を図〇に示す。
　◎：面取り部が意図した形状に形成され、締結バンドの食い込みやエッジ切れが起こらない。
　〇：面取り部の形成がやや不十分だが、締結バンドの食い込みやエッジ切れが起こらない。意図した機能が概ね機能しており、食い込みが発生しにくい。
　×：締結バンドの食い込みやエッジ切れが起こっている。  (Fixing test)
In the fastening test, packaging boxes containing instant food in containers were stacked in three stages as shown in FIG. 4, and fastening bands were hung in the width direction and the length direction. The fastening band was tightened so that the fastening band did not bend and was in close contact with the surface. At this time, it was confirmed whether the fastening band was biting into the corner of the packaging box or the edge was cut. The judgment criteria are as follows. The results are shown in Fig. 0.
⊚: The chamfered portion is formed in the intended shape, and the fastening band does not bite or the edge is cut.
〇: The chamfered part is not formed sufficiently, but the fastening band does not bite or the edge is cut. The intended function is generally functioning, and biting is unlikely to occur.
X: The fastening band is biting or the edge is cut.

　表２から明らかなように、実施例１～４では製函不良は起こらなかった。また、いずれの実施例においても、締結試験で食い込みやエッジ切れは起こらなかった。このことから、補助罫線を裏ライナ（包装箱の内側）に設けることで、製函性と締結バンドの食い込み防止に役立つことが示唆された。なお、実施例１～４について比較すると、補助罫線だけでも締結バンドの食い込み対策として十分であるが、ミシン目を設けることでより面取り部が意図した形状に形成され、締結バンドの食い込みを防ぐのに有効であることがわかる。特に、ミシン面を表裏両面に設けた場合、面取り部の形成が容易となる。 As is clear from Table 2, no box-making failure occurred in Examples 1 to 4. Moreover, in any of the examples, no biting or edge cutting occurred in the fastening test. From this, it was suggested that providing an auxiliary ruled line on the back liner (inside the packaging box) would help box-making and prevent the fastening band from biting. Comparing Examples 1 to 4, the auxiliary ruled line alone is sufficient as a countermeasure against the biting of the fastening band, but by providing the perforation, the chamfered portion is formed in a more intended shape to prevent the fastening band from biting. It turns out that it is effective for. In particular, when the sewing machine surfaces are provided on both the front and back surfaces, the chamfered portion can be easily formed.
　以上、説明したように、本発明においては、補助罫線を包装箱の内面側に設けることで、製函時の製函不良の発生を抑えつつ、締結バンドによる締結時には面取り部を形成させることができる。これにより、締結バンドの食い込みやエッジ切れを防ぐことができるという効果を奏する。 As described above, in the present invention, by providing the auxiliary ruled line on the inner surface side of the packaging box, it is possible to form a chamfered portion at the time of fastening with the fastening band while suppressing the occurrence of box-making defects during box-making. can. This has the effect of preventing the fastening band from biting into and cutting the edge.
