Description

この発明は、縦横に並べたボトルや缶の包装に使用するラップアラウンド式の包装箱の改良に関する。 The present invention relates to an improvement of a wrap-around type packaging box used for packaging bottles and cans arranged vertically and horizontally.

従来、ボトル飲料や缶飲料の包装箱として段ボール製のラップアラウンド式の包装箱が使用されている。
この種の包装箱３０としては、例えば図１４及び図１５に示すように対向する長側面となる一対の立面板２１、２１’と、上面板２２と下面板２２’とを交互に設け、立面板２１、２１’の両端に内フラップ片２３、２３’を、上面板２２と下面板２２’の両端に外フラップ片２４、２４’を設けて短側面となし、ブランクの端部となるように立面板２１の外側に貼付代２６を設けている。
この貼付代２６は上面板２２の一方の端部と重ね合わせて一体に接着されている。
そのため、アセプティック充填品では、充填後に一定量の割合で製品包装箱を開封し、内容品の検査を実施後に再封かんして製品化しているが、従来のラップアラウンド式の紙容器ではケースの開封範囲が広く、再封緘作業にも手間が掛かる繁雑な作業となっている。
また、貼付代２６は上面板２２の一方の端部と重ね合わせて一体に接着されると共に、図１４（ｂ）に示すように、重合せ部が包装箱に収納される円筒状の缶の頭部の一部と衝合して、上面板２２の端部が帯状に隆起した状態となり、包装箱を積み重ねた際に一方に傾いてしまい、段積み作業に手間がかかる虞れがあった。
また、内外フラップ片２３、２３’、２４、２４’を重ね合わせて対向する一対の端壁面（短側面）とした胴部の上下に、上面板２２と下面板２２’とが配置され、上記胴部の立面板２１、２１’の中央に、胴部を上下に分割するためのカットテープＴの切始部２８が設けられている。
更に、包装箱の胴部形成には、４面以外に別途に貼付代２６が必要となるためその部分だけ幅が広がり、長尺の原材料からブランクを裁断する際の長さが増えコストアップが避けられなかった。 Conventionally, cardboard wrap-around packaging boxes have been used as packaging boxes for bottled beverages and cans.
As this type of packaging box 30, for example, as shown in FIGS. 14 and 15, a pair of elevation plates 21, 21 ′ that are opposed long sides, an upper surface plate 22, and a lower surface plate 22 ′ are alternately provided. Inner flap pieces 23 and 23 'are provided at both ends of the face plates 21 and 21', and outer flap pieces 24 and 24 'are provided at both ends of the upper surface plate 22 and the lower surface plate 22' so as to form a short side surface so as to be an end portion of the blank. A sticking allowance 26 is provided outside the elevation plate 21.
This sticking allowance 26 is superposed on one end of the top plate 22 and bonded together.
For this reason, in aseptic filling products, the product packaging box is opened at a fixed rate after filling, and after the contents are inspected, they are resealed and commercialized, but in conventional wrap-around paper containers, the case is opened. It is a complicated work that has a wide range and takes time and effort to reseal.
The sticking allowance 26 overlaps with one end portion of the upper surface plate 22 and is integrally bonded, and as shown in FIG. 14B, the overlapping portion of the cylindrical can accommodated in the packaging box. It collided with a part of the head, and the end of the upper surface plate 22 was raised in a band shape, and when the packaging boxes were stacked, it was inclined to one side, and there was a possibility that it would take time for stacking work. .
Further, an upper surface plate 22 and a lower surface plate 22 ′ are arranged above and below a body portion which is a pair of end wall surfaces (short side surfaces) facing each other by overlapping the inner and outer flap pieces 23, 23 ′, 24, 24 ′. A cut start portion 28 of the cut tape T for dividing the barrel portion into upper and lower portions is provided at the center of the vertical plate 21, 21 ′ of the trunk portion.
Furthermore, in order to form the body portion of the packaging box, an additional sticking allowance 26 is required in addition to the four surfaces, so that only that portion is widened, and the length when cutting a blank from a long raw material increases, resulting in an increase in cost. It was inevitable.

一方、特開２００３−１４６３２９（特許第４００４２７３号）の包装箱では、各一対の立面板及び平面板を連設して、縦横に配列した複数の商品を巻き込み、各立面板及び平面板の両端縁にそれぞれ連設したフラップを貼り合せて封緘するラップアラウンド式の段ボール製包装箱において、一対の立面板に、その隅部から中央側へ向けて斜めに延びる部分と、これに続いてその中間で水平方向に延びる部分とを有する座屈誘導線を押罫により形成し、上下の座屈誘導線の水平部分の間に、これらの座屈誘導線から離して、開封用の切始部を設けた構成が開示されている。
これにより上記構成では、立面板に座屈誘導線を設けたので、荷重がかかっても座屈誘導線に沿って屈曲するので、不規則な座屈線が現れにくくなる。
しかし、上記構成も４面とは別に継代を設ける必要があるので、包装箱を積み重ねた際に偏荷重がかかってしまうし、貼合せ部の開封、再封緘は繁雑であり、また材料が増えコストアップは避けられなかった。
更に、上下の座屈誘導線で囲んだ水平部分の領域内に、これらから離して切目からなる開封用の切始部を設けるので、切目によって立面板の強度が弱まるという問題点もあった。 On the other hand, in the packaging box disclosed in Japanese Patent Application Laid-Open No. 2003-146329 (Japanese Patent No. 4004273), a pair of vertical plates and flat plates are connected in series, and a plurality of products arranged vertically and horizontally are entrained. In a wrap-around type corrugated cardboard packaging box in which flaps continuously connected to the edges are bonded and sealed, a pair of elevation plates, a portion extending obliquely from the corner toward the center, and subsequently the middle Forming a buckling guide line having a portion extending in the horizontal direction with a ruled line, and separating the horizontal portion of the upper and lower buckling guide lines away from these buckling guide lines, and opening a cut-out opening for opening. The provided arrangement is disclosed.
Thereby, in the said structure, since the buckling induction line was provided in the elevation board, even if a load is applied, it bends along a buckling induction line, Therefore An irregular buckling line becomes difficult to appear.
However, since the above-described configuration also needs to be provided with a passage in addition to the four sides, an unbalanced load is applied when the packaging boxes are stacked, and the unsealing and resealing of the laminating portion is complicated, and the material is Increased cost was inevitable.
Further, since the opening start portion made of a notch is provided in the region of the horizontal portion surrounded by the upper and lower buckling guide lines, there is a problem that the strength of the elevation plate is weakened by the notch.

この発明は、平面板及び外フラップ片を二分割した平面板構成片及び外フラップ構成片の外端に沿って重合せ部を設けて各立面板の外側に連接したファイブパネル構造からなり、平面板構成片の重合せ部を重ね合わせて平面板とし、外フラップ構成片を内フラップ片と接着することで、包装箱の段積みを容易にし、原紙の使用量の減少と、前記外フラップ構成片の重合せ部の貼合せ個所の開封、再封緘の容易さを実現した。
以下に、この発明の包装箱の好適実施例について図面を参照しながら説明する。 The present invention comprises a five-panel structure in which overlapping portions are provided along the outer ends of the flat plate constituting piece and the outer flap constituting piece obtained by dividing the flat plate and the outer flap piece, and are connected to the outside of each elevation plate. By superimposing the overlapping parts of the face plate component pieces to form a flat plate, the outer flap component pieces are bonded to the inner flap pieces, thereby facilitating the stacking of packaging boxes, reducing the amount of base paper used, and the outer flap structure. Easier opening and resealing of the bonded part of the overlapped part of the pieces.
Hereinafter, preferred embodiments of the packaging box of the present invention will be described with reference to the drawings.

［包装箱］
本実施例の包装箱１０は、図１から図３に示すように、１枚の段ボール等の厚紙製のブランク１０’を折って四角筒状の胴部を有する箱型に組立てられる包装箱からなっている。 [Packaging box]
As shown in FIGS. 1 to 3, the packaging box 10 of the present embodiment is a packaging box that is assembled into a box shape having a rectangular cylindrical body by folding a cardboard blank 10 ′ such as cardboard. It has become.

［ブランク］
このブランク１０’は、包装箱の左右の長側面となる一対の立面板１、１’の間に底壁面となる平面板２’が配置され、一対の立面板１、１’の外側に上壁面となる一対の平面板構成片２Ａ、２Ｂがそれぞれ図中点線で示す折目線を介して交互に連設されている。 [blank]
In this blank 10 ', a plane plate 2' serving as a bottom wall surface is disposed between a pair of elevation plates 1, 1 'serving as left and right long sides of the packaging box, and is disposed above the pair of elevation plates 1, 1'. A pair of flat plate constituting pieces 2A, 2B serving as wall surfaces are alternately arranged via crease lines indicated by dotted lines in the drawing.

［平面板構成片］
平面板構成片２Ａ、２Ｂは、平面板２’の幅の半分より僅かに長く設定されている。
即ち、平面板２’の幅ｗ１の半分より長く設定された部分が、胴部形成時の実質的な重合せ個所となるが、本実施例では従来の貼合せ部分となる貼付代２６の半分未満の幅長（図示例では貼付代の１／４程度の１０ｍｍ）に設定されている。 [Flat plate component]
The flat plate component pieces 2A and 2B are set slightly longer than half the width of the flat plate 2 ′.
That is, the portion set longer than half of the width w1 of the flat plate 2 ′ becomes a substantial overlap portion when forming the body portion, but in this embodiment, it is half of the pasting allowance 26 that becomes a conventional pasting portion. It is set to a width less than 10 mm (10 mm, which is about 1/4 of the pasting allowance in the illustrated example).

これは、重合せ部が平面板構成片２Ａ、２Ｂだけでなく後述の外フラップ構成片４Ａ、４Ｂにも及ぶからである。
従って、平面板２’の幅ｗ１を２６６ｍｍとした場合、平面板構成片２Ａ、２Ｂの幅ｗ３はそれぞれ１４３ｍｍに設定される。
そして立面板１、１’を２２１ｍｍとした場合、幅の全長（ｗ１＋ｗ２×２＋ｗ３×２）は９９４ｍｍとなる。
これに対して、従来の貼付代２６の幅ｗ４は平面板にのみ連接しているので幅広に設定する必要があり、前記貼付け部分の幅の倍以上の幅に設定されている。 This is because the overlapping portion extends not only to the flat plate constituting pieces 2A and 2B but also to the outer flap constituting pieces 4A and 4B described later.
Accordingly, when the width w1 of the flat plate 2 ′ is 266 mm, the width w3 of the flat plate constituting pieces 2A and 2B is set to 143 mm.
When the elevation plates 1 and 1 ′ are 221 mm, the total length (w1 + w2 × 2 + w3 × 2) is 994 mm.
In contrast, the width w4 of the conventional pasting allowance 26 is connected to only the flat plate, so it needs to be set wide, and is set to a width more than double the width of the pasted portion.

そのため、図１に示すように長尺の原紙からブランクを裁断する際には、本実施例のブランクの全幅は従来構成より短いので、従来より多くのブランク数を裁断することができ、コストダウンを図ることができる。
尚、展開時の立面板１、１’及び平面板２’及び平面板構成片２Ａ、２Ｂの図中縦方向の長さはいずれも４０１ｍｍであり、フラップ片を含めた縦方向の全長は６２２ｍｍである。 Therefore, as shown in FIG. 1, when the blank is cut from the long base paper, the entire width of the blank of this embodiment is shorter than the conventional configuration, so that the number of blanks can be cut more than before, thereby reducing the cost. Can be achieved.
In addition, the vertical length in the drawing of the elevation plates 1, 1 ′, the flat plate 2 ′, and the flat plate constituting pieces 2A, 2B when deployed is 401 mm, and the total length in the vertical direction including the flap pieces is 622 mm. It is.

また、各立面板１、１’の両端縁には内フラップ片３、３’が図中点線で示す折目線を介して連設され、平面板２’の両端縁には外フラップ片４’が図中点線で示す折目線を介して連設され、前記平面板構成片２Ａ、２Ｂの両端縁には外フラップ構成片４Ａ、４Ｂが図中点線で示す折目線を介して連設されている。
なお、平面板２の中央の丸で囲った部分は段ボールの繊維の目の方向を示す。 Further, inner flap pieces 3, 3 'are connected to both end edges of each elevation plate 1, 1' via a crease line indicated by a dotted line in the figure, and outer flap pieces 4 'are attached to both end edges of the plane plate 2'. Are connected via a crease line indicated by a dotted line in the figure, and outer flap constituent pieces 4A and 4B are provided continuously via a crease line indicated by a dotted line in the figure at both ends of the flat plate constituent pieces 2A and 2B. Yes.
The portion surrounded by a circle at the center of the flat plate 2 indicates the direction of the fiber of the cardboard.

［重合せ部］
前記一方の平面板構成片２Ａの外端側と他方の平面板構成片２Ｂの外端側にはそれぞれ平面板２の形成時に中央で上下に重なる重合せ部６Ａ、６Ｂが形成されている。
また、本実施例では、一方の外フラップ構成片４Ａの外端側と他方の外フラップ構成片４Ｂの外端側にもそれぞれ外フラップ片４、４’の形成時に中央で上下に重なる重合せ貼付部６Ａ’、６Ｂ’が形成されている。
前記の通り、平面板組立時に実質的な重合せ個所は１０ｍｍ程度となるが、本実施例では、各重合せ部６Ａ、６Ｂは成形誤差を含めて２５ｍｍの幅に設定している。
そして、前記一対の平面板構成片２Ａ、２Ｂに形成される重合せ部６Ａ、６Ｂには接着剤層を設けず、一対の外フラップ構成片４Ａ、４Ｂに形成される重合せ貼付部６Ａ’、６Ｂ’には上下に重合せた面を接着するためのホットメルト等の接着剤層を設けている。
これにより重合せ貼付部６Ａ’、６Ｂ’相互が接着されて一体となった外フラップ片４、４’が内フラップ片３、３’に接着される。 [Polymerized part]
Superposed portions 6A and 6B are formed on the outer end side of the one flat plate constituting piece 2A and the outer end side of the other flat plate constituting piece 2B, respectively, and overlap each other at the center when the flat plate 2 is formed.
Further, in the present embodiment, superposition is vertically overlapped at the center when forming the outer flap pieces 4, 4 'on the outer end side of one outer flap constituting piece 4A and the outer end side of the other outer flap constituting piece 4B, respectively. Pasting portions 6A ′ and 6B ′ are formed.
As described above, the substantial overlap portion is about 10 mm when the flat plate is assembled. In this embodiment, the overlap portions 6A and 6B are set to a width of 25 mm including a forming error.
The superposed portions 6A and 6B formed on the pair of flat plate constituting pieces 2A and 2B are not provided with an adhesive layer, and the superposed pasting portions 6A ′ formed on the pair of outer flap constituting pieces 4A and 4B. , 6B ′ is provided with an adhesive layer such as hot melt for bonding the surfaces superposed vertically.
Accordingly, the outer flap pieces 4, 4 ′, which are superposed with each other, are bonded to the inner flap pieces 3, 3 ′.

上記重合せ部６Ａ、６Ｂは、包装箱１０に収納する縦横に並んだ複数の容器、例えば缶飲料の列と列の間に配置することが好ましい。
図５（ａ）には実施例１と同じく平面板構成片２Ａ、２Ｂが同じ幅に設定された場合であって、包装箱１０に４つ並んだ缶飲料を２列収納する場合を図示しており、重合せ部６Ａ、６Ｂは、平面板２の中央に配置される。
この場合、重合せ部６Ａ、６Ｂと缶飲料の頭部との接触面積は狭く、図中ハッチングで示した部分が非接触部分となり、包装箱１０の段積みに際して隆起する重合せ部６Ａ、６Ｂを包装箱１０の内側に撓ませることができるので、積重ね姿勢を安定させることができる。
また、重合せ貼付部６Ａ’、６Ｂ’の接着により重合せ部６Ａ、６Ｂの重合姿勢も強く保持される。 It is preferable to arrange | position the said superposition | polymerization parts 6A and 6B between the row | line | columns of several containers arranged in the vertical and horizontal, for example, can drinks, accommodated in the packaging box 10. FIG.
FIG. 5A illustrates the case where the flat plate component pieces 2A and 2B are set to the same width as in the first embodiment, and two cases of canned drinks arranged in the packaging box 10 are stored. The overlapping portions 6A and 6B are arranged in the center of the flat plate 2.
In this case, the contact area between the superposed portions 6A and 6B and the head portion of the can beverage is narrow, and the hatched portion in the figure becomes a non-contact portion, and the superposed portions 6A and 6B are raised when the packaging box 10 is stacked. Can be bent to the inside of the packaging box 10, so that the stacked posture can be stabilized.
Moreover, the superposition | polymerization attitude | position of superposition | polymerization part 6A, 6B is strongly hold | maintained by adhesion | attachment of superposition pasting part 6A ', 6B'.

図５（ｂ）は、一方の平面板構成片２Ａが幅狭で、他方の平面板構成片２Ｂが幅広の場合であって、包装箱１０に缶飲料を３列収納する場合を図示しており、重合せ部６Ａ、６Ｂは、缶飲料の１列目と２列目の間に配置されている。
この場合であっても、同様に包装箱１０の段積みに際して隆起する重合せ部６Ａ、６Ｂを包装箱１０の内側に撓ませることができるので、積重ね姿勢を安定させることができる。 FIG. 5B illustrates the case where one flat plate constituting piece 2A is narrow and the other flat plate constituting piece 2B is wide, and three cases of canned drinks are stored in the packaging box 10. The superposed portions 6A and 6B are arranged between the first and second rows of the can beverage.
Even in this case, since the overlapping portions 6A and 6B, which are similarly raised when the packaging boxes 10 are stacked, can be bent to the inside of the packaging box 10, the stacking posture can be stabilized.

［成形方法］
包装箱１０は、ブランク１０’の折目線に沿って、平面板２’や立面板１、１’を折り曲げながらボトル飲料などの収納物（図示せず）を包み込むように収納し上面の平面板構成片２Ａ，２Ｂを折り曲げ、重合せ部６Ａ、６Ｂの少なくとも一部を上下に重ねただけで相互には接着せずに平面板２を形成し筒状の胴部を形成する。
また、外フラップ構成片４Ａ、４Ｂでは、同様に対向する重合せ貼付部６Ａ’、６Ｂ’を上下に重ね、重合せた個所を接着剤層によって接着して一体となった外フラップ片４、４’を形成する。 [Molding method]
The packaging box 10 is accommodated so as to wrap a container (not shown) such as a bottled beverage while folding the flat plate 2 'and the elevation plates 1, 1' along the crease line of the blank 10 '. The component pieces 2A and 2B are bent and at least a part of the overlapping portions 6A and 6B are stacked one on top of the other, and the flat plate 2 is formed without bonding to each other to form a cylindrical body.
Further, in the outer flap constituting pieces 4A and 4B, similarly, the opposite overlapping overlapping portions 6A 'and 6B' are vertically stacked, and the overlapped portions are bonded together by an adhesive layer to be integrated, 4 ′ is formed.

次いで、立面板１’の折目線に沿って内フラップ片３’を開口の左右方向の一方の外側から内側に折り曲げ、対向する立面板１で同じ方向に延びる一対の内フラップ片３によって開口側を左右方向の他方の外側から塞ぐ。
更に、対向する平面板２、２’で同じ方向に延びる外フラップ片４、４’を折目線に沿って上下から前記内フラップ片３、３’の外側に重なるように内向きに折り曲げ、上下一対の外フラップ片４、４’を内フラップ片３、３’と重なり合った部分で接着して前記胴部の開口を塞ぐ短側面を形成する。 Next, the inner flap piece 3 ′ is bent inward from one outer side in the left-right direction of the opening along the fold line of the elevation plate 1 ′, and the opening side is formed by a pair of inner flap pieces 3 extending in the same direction on the opposite elevation plate 1. Is closed from the other outside in the left-right direction.
Further, the outer flap pieces 4 and 4 ′ extending in the same direction on the opposing flat plates 2 and 2 ′ are bent inward so as to overlap the outer side of the inner flap pieces 3 and 3 ′ along the crease line. A pair of outer flap pieces 4, 4 ′ are bonded at portions overlapping the inner flap pieces 3, 3 ′ to form a short side surface that closes the opening of the body portion.

ここで、下方の外フラップ片４’は、その外端辺部が、中央で突出する凸片部４ａ’と、該凸片部４ａ’の基端側が円弧状に湾曲してから凸片部４ａ’の先端辺と平行に左右方向の端部まで段違い状に延びる一対の長孔構成縁部４ｂ’とを有している（図１参照）。 Here, the lower outer flap piece 4 ′ has a convex piece portion 4a ′ whose outer end side portion protrudes at the center, and a convex piece portion after the base end side of the convex piece portion 4a ′ is curved in an arc shape. It has a pair of long hole constituting edge portions 4b ′ extending in a stepwise manner to the end portions in the left-right direction in parallel with the front end side of 4a ′ (see FIG. 1).

同様に、上方の外フラップ片４となる外フラップ構成片４Ａ、４Ｂは、その外端辺部が、端部となる重合せ部６Ａ’、６Ｂ’側で前記凸片部４ａ’を分割した凸片部構成部４ａを突設しており、その先端辺と平行に左右方向の立面板１、１’の折目線側まで段違い状に延びる１つの長孔構成縁部４ｂとを有しており、外フラップ構成片４Ａ、４Ｂを重合せ部６Ａ’、６Ｂ’で相互に接着し貼り合わせることで、前記下方の外フラップ片４’と同様の形状となる。 Similarly, the outer flap constituent pieces 4A and 4B which are the upper outer flap pieces 4 are obtained by dividing the convex piece portion 4a 'on the overlapping portions 6A' and 6B 'side where the outer end side portions become the end portions. Convex projecting portion constituting portion 4a is provided, and has one elongated hole constituting edge portion 4b extending in a stepped manner to the crease line side of the upright plate 1, 1 'in the left-right direction parallel to the tip side. Then, the outer flap constituent pieces 4A, 4B are bonded to each other at the overlapping portions 6A ′, 6B ′, and bonded together to form the same shape as the lower outer flap piece 4 ′.

そこで上下の外フラップ片４、４’が折り曲げられることで、図３に示すように中央位置は前記一対の凸片部４ａ、４ａ’によって上下に略隙間無く接する中央連設部４Ａが形成され、その両側には前記長孔構成縁部４ｂ、４ｂ’が上下に組み合わさって端部で開口する横倒Ｕ字状の長孔４Ｃが左右一対に形成される公知形状からなっている。 Therefore, the upper and lower outer flap pieces 4 and 4 ′ are bent to form a central connecting portion 4A that is in contact with the pair of convex piece portions 4a and 4a ′ in the vertical direction with almost no gap as shown in FIG. On both sides, the long hole-constituting edge portions 4b and 4b 'are vertically combined with each other to form a well-known shape in which a pair of laterally U-shaped long holes 4C opened at the ends are formed.

［切始部］
各立面板１の延出方向に設けられた一対の内フラップ片３には、立面板１を挟んで対向する側の内フラップ片３に、それぞれ切始部８、８’が形成される。
該切始部８（８’も同じ）は、図４（ａ）に示すように、前記内フラップ片３の外端部より僅かに内側に離間した中央位置で、指を押し当てるための内向きの円弧状の切目からなる円弧部８ａと、該円弧部８ａの両端から立面板１側に向かって徐々に幅狭となる点線状の内ガイド切目８ｂと、円弧部８ａの一方の端部から内フラップ片３の外端部に向かって延びる外ガイド切目８ｃとを有している。 [Starting part]
In the pair of inner flap pieces 3 provided in the extending direction of each elevation plate 1, cut portions 8, 8 ′ are formed in the inner flap pieces 3 on the opposite side across the elevation plate 1.
As shown in FIG. 4A, the incision portion 8 (same as 8 ') is an inner portion for pressing a finger at a central position slightly spaced from the outer end portion of the inner flap piece 3. A circular arc portion 8a composed of an arc-shaped cut in the direction, a dotted inner guide cut 8b gradually narrowing from both ends of the circular arc portion 8a toward the elevation plate 1, and one end portion of the circular arc portion 8a And an outer guide cut 8 c extending toward the outer end of the inner flap piece 3.

また、一方の内フラップ片３、３’から立面板１、１’を長手方向に通り抜け、他方の内フラップ片３、３’の端部まで中心線に沿って一連に続くカットテープ（図示せず）を裏面側に貼着しておき、前記内ガイド切目８ｂが切り取られた切片とカットテープの先端とが一連につながるように設定しておくことが好ましい。 Further, a cut tape (not shown) passes through the elevation plates 1 and 1 'in the longitudinal direction from one inner flap piece 3 and 3', and continues along the center line to the end of the other inner flap piece 3 and 3 '. It is preferable that the section where the inner guide cut 8b is cut and the tip of the cut tape are connected in series.

［把持用切目］
本実施例では、外フラップ片の一方、図示例では箱組立時の下部側の外フラップ片４’に把持用切目５が形成されている。
この把持用切目５は、図４（ｂ）に示すように、中央に設けられた縦線５ａと、縦線５ａの下端で僅かに隙間を空けて左右に伸びる一対の横線５ｂ、５ｃと、縦線５ａの上端より僅かに上方で小さな円弧状に形成された頂上線５ｄと、前記左右の横線５ｃ、５ｃから外側に無かって斜めに立ち上がり上端が外側に円弧状に折れ曲がる側方線５ｅ、５ｆと、該側方線５ｅ、５ｆと前記頂上線５ｄとを結ぶ上部傾斜線５ｇ、５ｈとからなっている。
この発明で把持用切目は、把持用に手指を挿入しうる切欠を形成しうるものであればよく、その位置も上部側又は下部側の外フラップ面のいずれでもよく、あるいは設けなくてもよい。 [Grip for gripping]
In the present embodiment, a grip notch 5 is formed on one of the outer flap pieces, in the illustrated example, on the lower outer flap piece 4 'when the box is assembled.
As shown in FIG. 4 (b), the grasping cut 5 includes a vertical line 5a provided at the center, and a pair of horizontal lines 5b and 5c extending left and right with a slight gap at the lower end of the vertical line 5a.

In the present invention, the grip notches need only be capable of forming notches into which fingers can be inserted for gripping, and the position thereof may be either the upper or lower outer flap surface or may not be provided. .

［切欠］
また、把持用切目５を設けた場合には、内フラップ片３、３’の端部で前記把持用切目５と箱組立時に重なる個所には、該切目５に沿って押し込んだ際に障害とならないように略半円状の切欠１１、１１’を透設することが好ましい。
このように、包装箱１０は、平面板構成片２Ａ、２Ｂで形成された平面板２の中央に沿って段部となる重合せ部６Ａ、６Ｂが配置されるので、積荷状態でも平面板２に均等に荷重を分散できる。
また平面板２の重合せ部６Ａ、６Ｂは接着されず、外フラップ構成片４Ａ、４Ｂで形成された外フラップ片４で重合せ部６Ａ’、６Ｂ’だけが接着されるので、開封、再封緘が容易となり、更にコストダウンを図ることができる。
そして、前記切始部８、８’に沿って包装箱１０を上下に２分割してトレイとして使用することができる。 [Notch]
Further, in the case where the grip cut 5 is provided, the end of the inner flap pieces 3, 3 ′ is overlapped with the grip cut 5 when the box is assembled. It is preferable that the substantially semicircular cutouts 11 and 11 ′ are transparently provided so as not to be formed.
In this way, the packaging box 10 is provided with the overlapping portions 6A and 6B that become step portions along the center of the flat plate 2 formed by the flat plate constituting pieces 2A and 2B. The load can be distributed evenly.
Further, the overlapping portions 6A and 6B of the flat plate 2 are not bonded, and only the overlapping portions 6A ′ and 6B ′ are bonded by the outer flap piece 4 formed by the outer flap constituting pieces 4A and 4B. Sealing is easy, and cost can be further reduced.
And the packaging box 10 can be divided into 2 parts up and down along the said cut start parts 8 and 8 ', and it can be used as a tray.

実施例２はペットボトルやボトル缶等のネック部を有する形状の容器を収納するラップアラウンド式の紙容器１０であって、段積み積載時の荷重がかかって紙容器が胴膨れする虞れがあっても、これを抑制するために、胴部の上方を台形状にした異なる実施例を示す。 The second embodiment is a wrap-around type paper container 10 for storing a container having a neck portion such as a plastic bottle or a bottle can, and there is a possibility that the paper container may swell due to a load upon stacking. Even if it exists, in order to suppress this, the different Example which made the upper part of the trunk | drum into trapezoid shape is shown.

［傾斜面］
即ち、図６〜図８に示すように、平面板構成片２Ａと折目線Ｌ１を介して接する立面板１との間に、該折目線Ｌ１の両端から立面板１と内フラップ片３、３’との折目線Ｌ２に向かって延びる一対の切込線１５が形成されている。
また、該切込線１５の先端間を結ぶ折目線Ｌ３が前記折目線Ｌ１と平行に形成されており、箱組立時に左右の立面板１、１’の上部が内向きに傾斜する傾斜面９となる。 [Inclined surface]
That is, as shown in FIGS. 6 to 8, between the flat plate constituting piece 2A and the elevation plate 1 that is in contact with the crease line L1, the elevation plate 1 and the inner flap pieces 3, 3 from both ends of the crease line L1. A pair of cut lines 15 extending toward the crease line L2 is formed.
Further, a crease line L3 connecting the leading ends of the cut lines 15 is formed in parallel with the crease line L1, and an inclined surface 9 in which the upper portions of the left and right elevation plates 1, 1 ′ are inclined inward when the box is assembled. It becomes.

前記切込線１５は、図６に示すように、内フラップ片３、３’の折目線Ｌ２に沿って延び折目線Ｌ１−Ｌ３間で囲まれた傾斜面９の縁部となる直線部分１５ａと、立面板１、１’に隣接する内フラップ片３、３’で傾斜面９の折目線Ｌ１の端部と接する個所を斜めに切欠く傾斜線部分１５ｂとを有しており、内フラップ片３、３’で傾斜面９の折目線Ｌ１の端部と接する側で切り離された略三角形状の切欠が形成されている。
これにより、傾斜面９を立面板１、１’や平面板構成片２Ａ、２Ｂに対して傾斜させ、内フラップ片３、３’の傾斜線部分１５ｂが形成された面が上記傾斜面９の端部を外側から覆うので、図７及び図８に示すように、上部が略台形となる包装箱１０を組み立てることができる。 As shown in FIG. 6, the cut line 15 extends along the crease line L2 of the inner flap pieces 3 and 3 ', and is a straight line portion 15a that becomes the edge of the inclined surface 9 surrounded by the crease lines L1-L3. And an inclined line portion 15b that obliquely cuts out a portion of the inner flap piece 3, 3 'adjacent to the elevation plate 1, 1' that contacts the end of the crease line L1 of the inclined surface 9, and the inner flap A substantially triangular notch separated by the pieces 3 and 3 ′ on the side in contact with the end of the crease line L 1 of the inclined surface 9 is formed.
Thereby, the inclined surface 9 is inclined with respect to the upright plates 1, 1 ′ and the flat plate constituting pieces 2 A, 2 B, and the surface on which the inclined line portion 15 b of the inner flap pieces 3, 3 ′ is formed is the inclined surface 9. Since the end portion is covered from the outside, as shown in FIGS. 7 and 8, the packaging box 10 whose upper portion is substantially trapezoidal can be assembled.

図９（ａ）には切込線１５の異なる構造のブランク１０’を示す。
即ち、内フラップ片３、３’の折目線Ｌ２に沿って延び折目線Ｌ１−Ｌ３間で囲まれた傾斜面９の縁部となる直線部分１５ａと、立面板１、１’に隣接する内フラップ片３、３’で傾斜面９の折目線Ｌ１の端部と接する個所を斜めに切欠く傾斜線部分１５ｂ’と、外フラップ構成片４Ａ、４Ｂで傾斜線部分１５ｂ’と対峙して折目線Ｌ３の端部から斜めに切欠く外傾斜線部分１５ｃとからなる略三角形状の切欠が形成されている。
これにより、傾斜面９を立面板１、１’や平面板構成片２Ａ、２Ｂに対して傾斜させ、外フラップ片構成片４Ａ、４Ｂの外傾斜線部分１５ｃが上記傾斜面９の端部を外側から覆うので、図９（ｂ）に示すように上部が略台形となる包装箱１０を組み立てることができる。 FIG. 9A shows a blank 10 ′ having a different structure of the cut line 15.
That is, it extends along the crease line L2 of the inner flap pieces 3, 3 ′, and the linear portion 15a that becomes the edge of the inclined surface 9 surrounded by the crease lines L1-L3, and the inner surface adjacent to the elevation plates 1, 1 ′. Flap pieces 3 and 3 ′ are folded so as to be opposed to inclined line portion 15b ′ at an inclined portion 9b ′ which is obliquely cut out at a portion contacting the end of crease line L1 of inclined surface 9 and outer flap constituting pieces 4A and 4B. A substantially triangular cutout is formed that includes an outer inclined line portion 15c cut obliquely from the end of the line of sight L3.
Thereby, the inclined surface 9 is inclined with respect to the upright plates 1, 1 ′ and the flat plate constituting pieces 2 A, 2 B, and the outer inclined line portion 15 c of the outer flap piece constituting pieces 4 A, 4 B Since it covers from the outside, it is possible to assemble the packaging box 10 whose upper part is substantially trapezoidal as shown in FIG.

本実施例の内フラップ片３、３’は、図９（ａ）中の横幅の長さ（図９（ｂ）の箱組立時の高さ方向の長さ）Ｈを、包装箱１０に収納するネック部を有する容器の高さよりも短い長さに設定している。
内フラップ片３、３’の長さＨがネック部を有する容器の全高と同等であると内フラップ片３、３’に座屈が起こり、内フラップ片３、３’が変形して外フラップ片４、４’と離れたりする虞れがあるが、短い長さに設定することでて内フラップ片３、３’に座屈が起こりにくく包装箱１０の形状を復元しやすくすることができる。
この内フラップ片の長さに関する構成は、前記実施例１の構成においても同様である。 The inner flap pieces 3, 3 ′ of the present embodiment store the width H in FIG. 9A (the length in the height direction when the box is assembled in FIG. 9B) H in the packaging box 10. The length is set shorter than the height of the container having the neck portion.
If the length H of the inner flap pieces 3 and 3 ′ is equal to the total height of the container having the neck portion, the inner flap pieces 3 and 3 ′ are buckled, and the inner flap pieces 3 and 3 ′ are deformed and the outer flap is deformed. Although there is a possibility that it may be separated from the pieces 4 and 4 ′, by setting the length to be short, the inner flap pieces 3 and 3 ′ are less likely to buckle and the shape of the packaging box 10 can be easily restored. .
The configuration related to the length of the inner flap piece is the same as in the configuration of the first embodiment.

実施例２の図６、図９に示す重合せ部６Ａ、６Ｂは、前記実施例１と同様に、平面板構成片２Ａ、２Ｂが同じ幅に設定されている場合を例示している。
この場合の重合せ部６Ａ、６Ｂの位置とネック部を有する容器との位置関係を図１０に示す。
この場合、重合せ部６Ａ、６Ｂは小径のネック部とは接触することが無い（図中ハッチングで示す部分）ので、段積みに際しては、隆起部分は包装箱１０の内側に撓み、積み重ね姿勢は安定する。 The overlapping portions 6A and 6B shown in FIGS. 6 and 9 of the second embodiment illustrate the case where the flat plate component pieces 2A and 2B are set to have the same width as in the first embodiment.
FIG. 10 shows the positional relationship between the positions of the overlapping portions 6A and 6B and the container having the neck portion in this case.
In this case, the superposed portions 6A and 6B do not come into contact with the small-diameter neck portions (portions indicated by hatching in the figure), and therefore, when stacking, the raised portions bend inside the packaging box 10 and the stacking posture is Stabilize.

ここで、ブランク１０’の寸法の一例を示すと、展開時の立面板１、１’及び平面板２、２’の図中縦方向の長さはいずれも４０１ｍｍであり、底壁面となる平面板２’の横幅は２６６ｍｍ、フラップ片を含めた縦方向の全長は６２２ｍｍである。
また底壁面となる平面板２’の図中横方向となる横幅は２６６ｍｍであって前記実施例１と同じである。 Here, as an example of the dimensions of the blank 10 ', the vertical lengths of the upright plates 1, 1' and the flat plates 2, 2 'in the drawing are 401 mm in the drawing, and the flat surface serving as the bottom wall surface is shown. The width of the face plate 2 ′ is 266 mm, and the total length in the vertical direction including the flap pieces is 622 mm.
Further, the horizontal width in the horizontal direction in the drawing of the flat plate 2 ′ serving as the bottom wall surface is 266 mm, which is the same as in the first embodiment.

一方、立面板２、２’の横幅は、平面板２’の折目線から前記折目線Ｌ１までの横幅を１７６．５ｍｍとし、折目線Ｌ１とＬ３の間の横幅を４８ｍｍとし、折目線Ｌ３から立面板構成片２Ａ、２Ｂの端部までの横幅は１２５ｍｍに設定されており、横幅の全長は９６５ｍｍとなって、実施例１のブランク１０’の横幅９９４ｍｍよりも更に２９ｍｍ短く形成することができる。 On the other hand, the horizontal width of the elevation plates 2, 2 ′ is 176.5 mm from the crease line of the plane plate 2 ′ to the crease line L1, the lateral width between the crease lines L1 and L3 is 48 mm, and from the crease line L3. The horizontal width to the end of the upright plate component pieces 2A and 2B is set to 125 mm, the total length of the horizontal width is 965 mm, and can be formed 29 mm shorter than the horizontal width 994 mm of the blank 10 ′ of the first embodiment. .

包装箱１０に組み立てられた立面板１、１’は上部が傾斜面９となるので折板構造となって強度が高まる。
また、ボトル飲料の場合、頭部側が截頭円錐形状となっているので、これに沿って傾斜面９を傾斜させることができる。 The upright plates 1 and 1 ′ assembled in the packaging box 10 have an inclined surface 9 so that the folded plate structure increases the strength.
In the case of a bottled beverage, since the head side has a truncated cone shape, the inclined surface 9 can be inclined along this.

また、切込線１５によって内フラップ片３、３’の折目線側の辺３ａ、３ａ’は前記切込線の傾斜線部分１５ｂによって傾斜しており、箱組立時に立面板１、１’の傾斜面の端部と衝合するように外側から塞いでおり、外フラップ片４、４’が外側から重なって固着されて端壁面を形成している。
傾斜面を除いたその他の構成は前記実施例に準じるので、その説明を省略する。 Further, the side lines 3a, 3a 'on the fold line side of the inner flap pieces 3, 3' are inclined by the cut line 15 by the inclined line portion 15b of the cut line, and when the box plate is assembled, It is closed from the outside so as to abut against the end of the inclined surface, and the outer flap pieces 4, 4 'are overlapped and fixed from the outside to form an end wall surface.
Since other configurations excluding the inclined surface are the same as those in the above embodiment, the description thereof is omitted.

本実施例では包装箱１０の立面板１、１’は、収納される容器（例えばペットボトル）の足部（底面）から肩部までの長さに対応しており、図示例では１７６．５ｍｍに設定されている。
そして、傾斜面９は傾斜面９の傾斜時の高さが、前記ペットボトルの肩部から頭部（キャップ上端）までの長さに対応しており、図示例では４４．５ｍｍになるように、傾斜面９の幅が１７６．５ｍｍに設定されている。
なお、包装箱１０の全高は約２２１ｍｍである。 In this embodiment, the elevation plates 1 and 1 ′ of the packaging box 10 correspond to the length from the foot (bottom) to the shoulder of the container (for example, PET bottle) to be stored, and in the illustrated example, 176.5 mm. Is set to
The inclined surface 9 corresponds to the length from the shoulder portion of the PET bottle to the head (upper end of the cap) when the inclined surface 9 is inclined, and is 44.5 mm in the illustrated example. The width of the inclined surface 9 is set to 176.5 mm.
The overall height of the packaging box 10 is about 221 mm.

この発明では、傾斜面９は、収納されるボトル飲料の外壁面と接する程度の傾斜角が好ましく、また包装箱の上部で全高の１／２以内、より好ましくは１／４以内とすることが好ましいが、この発明では特に限定されない。 In the present invention, the inclined surface 9 preferably has an inclination angle that is in contact with the outer wall surface of the bottled beverage to be stored, and is preferably within ½ of the total height at the upper part of the packaging box, more preferably within ¼. Although preferred, this invention is not particularly limited.

これにより、立面板１、１’は、傾斜面９によって外側へ突出するので、強度の向上と相俟って胴膨れを吸収することができ、傾斜面９の下側となる立面板１、１’を太鼓状に胴膨れさせることなく垂直面に維持することができる。
その他の構成は、前記実施例１と同様であるので、その説明を省略する。 As a result, the upright plates 1, 1 ′ protrude outward by the inclined surface 9, so that the swelling can be absorbed together with the improvement in strength, and the upright plate 1, which is the lower side of the inclined surface 9, 1 'can be maintained on a vertical surface without causing drumming.
Since other configurations are the same as those of the first embodiment, the description thereof is omitted.

図１１から図１３は、実施例２と同様にネック部を有する形状の容器を収納するラップアラウンド式の紙容器１０であって、重合せ部６Ａ、６Ｂを上面の平面板２の中央ではなく一方に偏った位置に配置した異なる実施例を示す。
そのため平面板構成片２Ａを幅狭とし、平面板構成片２Ｂを幅広としている。 11 to 13 show a wrap-around type paper container 10 for storing a container having a shape having a neck portion as in the second embodiment, and the overlapping portions 6A and 6B are not located at the center of the upper flat plate 2. A different embodiment arranged at a position biased to one side is shown.
Therefore, the flat plate component piece 2A is narrow, and the flat plate component piece 2B is wide.

また、本実施例では、外フラップ構成片４Ａ、４Ｂに形成される重合せ貼付部６Ａ’、６Ｂ’を形成していない例を示す。
即ち、外フラップ構成片４Ａ、４Ｂは相互に重なる部分を設けておらず、各外フラップ構成片４Ａ、４Ｂを略隙間無く並べ同一面に揃えて内フラップ片３、３’にそれぞれ貼り付けることで外フラップ片４、４’となっている。
そのため、外フラップ構成片４Ａ、４Ｂの縁部は、重合せ部６Ａ、６Ｂの縁部と連続する延長線上には設けず、重合せ部６Ａ、６Ｂの重ね合せ部分を除いた部分（図示例では平面板構成片端縁部の幅の約半分）だけ内側に狭まった位置に設定されている。
これにより、図１２に示すように外フラップ４、４’は外フラップ構成片４Ａ、４Ｂ相互が接着されず、各外フラップ構成片４Ａ、４Ｂが個別に内フラップ片３、３’に接着されている（図１１参照）。
これによりブランクの面積を一層狭めることができる。 Moreover, in a present Example, the example which has not formed superposition pasting part 6A 'and 6B' formed in outer flap constituent pieces 4A and 4B is shown.
That is, the outer flap constituent pieces 4A and 4B are not provided with overlapping portions, and the outer flap constituent pieces 4A and 4B are arranged with substantially no gap and are aligned on the same surface and are respectively attached to the inner flap pieces 3 and 3 ′. The outer flap pieces 4 and 4 'are formed.
Therefore, the edges of the outer flap constituent pieces 4A and 4B are not provided on the extension line continuous with the edges of the overlapped portions 6A and 6B, and the portions excluding the overlapping portions of the overlapped portions 6A and 6B (illustrated example) In this case, it is set at a position narrowed inward by about half of the width of one edge of the flat plate structure.
Thereby, as shown in FIG. 12, the outer flaps 4 and 4 ′ are not bonded to each other, and the outer flaps 4A and 4B are individually bonded to the inner flaps 3 and 3 ′. (See FIG. 11).
As a result, the area of the blank can be further reduced.

実施例３の重合せ部６Ａ、６Ｂの位置とネック部を有する容器との位置関係を図１０に示す。
図示例では、６つの容器が４列に並んでおり、その４列の内の１列目と２列目の間に重合せ部６Ａ、６Ｂが配置されている。
重合せ部６Ａ、６Ｂの配置は図示例に限定されず、容器の列と列の間に配置されるものであれば、どの位置であってもよい。
これにより隆起する重合せ部６Ａ、６Ｂは下方へ撓み、包装箱１０の積み重ね姿勢は安定する。
その他の構成は、前記実施例２と同様であるので、その説明を省略する。
