Description

本発明は段ボールや厚紙からなる紙製の包装容器であって、液体が充填されたフレキシブルな合成樹脂容器を内容器として収納するに適した包装容器に関するものであり、さらに容器の使用後に解体が容易に行なえるようにした包装容器に関するものである。 The present invention relates to a packaging container made of paper made of cardboard or cardboard, and relates to a packaging container suitable for storing a flexible synthetic resin container filled with liquid as an inner container. The present invention relates to a packaging container that can be easily performed.

従来から、業務用途で提供する日本酒や焼酎などの飲料を収納する容器の一つとしてバッグインボックスが利用されている。このような業務用途のバッグインボックスは内容量が１０リットルを超えるものが多く、立方体状の段ボールケースにフレキシブルな合成樹脂製容器を内容器として収納しており、その内容器に取り付けられたスパウトを段ボールケースの側面板に開口した取り出し口から引き出してコックタイプの栓を取り付けて、バッグインボックス全体を支えなくとも据え置きの状態で内容物を注出できるようにしている。
また、近年においては、一般住宅で少人数の客を招いてホームパーティなどのような集まりを開く場合が目立つようになり、この小さな集まりに際しては、少人数の招待客にジュースやアルコール飲料を振る舞うことができるようにと、飲料が或る程度の数量を纏めて買い求められている。このような消費傾向から、一般家庭向けとして、上述した大容量のものではないが、２〜６リットル程度の内容量のバッグインボックスにジュースやアルコール飲料を収納した商品を提供する試みがある。 Conventionally, a bag-in-box has been used as one of containers for storing beverages such as sake and shochu provided for business use. Such business-use bag-in-boxes often have an internal capacity of more than 10 liters, and contain a flexible synthetic resin container as an inner container in a cubic cardboard case, and a spout attached to the inner container. Is pulled out from the outlet opening in the side plate of the cardboard case, and a cock-type stopper is attached so that the contents can be poured out in a stationary state without supporting the entire bag-in-box.
In addition, in recent years, in the residential invited guests of the small number of people would be the case stand out to open the collection, such as a home party, at the time of the small greens collection of Mari, the juice and alcoholic beverages to guests of the small number of people In order to be able to behave, beverages are being purchased in a certain quantity. From such a consumption trend, there is an attempt to provide a product in which juice or alcoholic beverages are stored in a bag-in-box having an internal capacity of about 2 to 6 liters, although it is not for the above-mentioned large capacity for general households.

上述したように内容量が２〜６リットル程度のバッグインボックスタイプとした容器としては手持ちできる形態が望ましいとともに、家庭の冷蔵庫に収納できる大きさとすることが考えられている。そして、その内容量の内容器を収納する外ケースとしての包装容器には、胴膨れを考慮して比較的剛性のある薄口の段ボールが包材として適し、また、一般消費者向けの商品としてその商品周囲に絵柄や取り扱い説明などを印刷した化粧面が形成できて、かつ見栄えも良くするために、正面板と背面板と左右側面板との四方の面板が一連に連接して胴部を形成した段ボール箱とし、さらには内容器を確実に支持するために、天面部分にあっては、正面板の上端と背面板の上端とに連接されて対向配置となった二枚の面板を折り倒してほぼ全面的に重ね合わせた二重の天面閉鎖の構成とするとともに、同様に底面部分についても、正面板の下端と背面板の下端とに連接されて対向配置となった二枚の面板を折り倒してほぼ全面的に重ね合わせた二重の底面閉鎖の構成とすることが望ましい。
内容器に取り付けられているスパウトを引き出すためには、胴部において正面板や背面板より細幅とした側面板に開口可能な部分を設けておき、必要時にこの部分を開いてスパウトを引き出すようにすることが、注出時に収納容器を取り扱う上で望ましいと考えられている。 As described above, a bag-in-box type container having an internal capacity of about 2 to 6 liters is desirable to have a form that can be held by hand, and is considered to have a size that can be stored in a household refrigerator. And, for packaging containers as outer cases that store inner containers of that capacity, thin-walled corrugated cardboard that is relatively rigid in consideration of swelling is suitable as a packaging material, and as a product for general consumers, In order to be able to form a decorative surface printed with pictures and handling instructions around the product and to improve its appearance, the front plate, the back plate, and the left and right side plates are connected in series to form the body In order to securely support the inner container, the two top plates that are connected to the top end of the front plate and the top end of the back plate are opposed to each other on the top surface. In addition to the configuration of a double top surface closure that is almost completely overlapped, the bottom surface portion is also connected to the lower end of the front plate and the lower end of the rear plate, and the two pieces are opposed to each other. The face plate was folded and almost completely overlaid It is desirable that the structure of the heavy bottom closure.
In order to pull out the spout attached to the inner container, a portion that can be opened on the side plate narrower than the front plate and the back plate is provided in the trunk, and this portion is opened when necessary to pull out the spout. It is considered desirable to handle the storage container at the time of dispensing.

一方、このような一般消費者向けに提供するバッグインボックスの商品にあっては、使用後には空の内容器である合成樹脂製容器と段ボールの収納容器とを分別して処分できるようにする必要がある。勿論、業務用途のバッグインボックスの商品であっても廃棄時に分別する必要があるが、一般消費者が内容器と収納容器とを容易に分別できるようにすべきである。 On the other hand, in such bag-in-box products provided for general consumers, it is necessary to separate and dispose of a synthetic resin container that is an empty inner container and a cardboard storage container after use. There is. Of course, even if it is a bag-in-box product for business use, it is necessary to separate it at the time of disposal, but it should be possible for a general consumer to easily separate the inner container and the storage container.

二重となっている天面部分については、摘み部などを構成し易いため、分別ではその二重の天面板の部分から開くようにすることが好ましい。そして、天面板部分に予め切り取りミシン目を穿設して、必要時にこの切り取りミシン目を切断することが考慮され、例えば特許文献１に示されているように、全面的に重ね合わされた二枚の天面板の内、上位の天面板の基端に沿って切り取りミシン目を二条にして穿設してなるファスナを設け、切り取りミシン目の間を取り外しながらファスナを切断することで、上位の天面板の大部分が下位の天面板に一体となった状態で箱の天面側を開くことができるようにした工夫がある。
このようにして天面板部分や底面板部分を開いて内容器を引き出すようにすれば分別が可能である。
また、二重の天面板や底面板はホットメルトによって貼り合わせすることになるが、特許文献２に示されているように、貼り合わせによって二重とされた面板の内、外表面側となる面板に対して、側面板側の折り罫とは反対側となる端縁の中央の部分を摘み部とし、その両側から切り取りミシン目を前記折り罫の端部それぞれに亘って設けて、切り取りミシン目を境として側方の領域を重ね合わせ下位のとなる内側の面板に接着した領域として、摘み部から引き起こしで切り取りミシン目それぞれを切断することで、貼り合わせしていた二枚の面板を分離できるようにした工夫がある。このようにすれば、閉鎖されていた天面側や底面側も開いて収納容器全体を偏平にすることが可能となり、ゴミの削減に効果があると考えられている。
特開平０５−１２４６３８号公報実公平０７−０４８５０５号公報 As for the top surface portion that is double, it is easy to configure a knob or the like, and therefore it is preferable to open from the portion of the double top surface plate in sorting. Then, it is considered that a cut perforation is previously drilled in the top plate portion and this cut perforation is cut when necessary. For example, as shown in Patent Document 1, two sheets that are entirely overlapped are used. A fastener is formed by cutting two perforations along the base end of the upper top plate, and cutting the fastener while removing the gap between the cut perforations. There is a device that allows the top side of the box to be opened in a state where most of the face plate is integrated with the lower top plate.
In this way, separation is possible by opening the top plate portion and the bottom plate portion and pulling out the inner container.
Further, the double top plate and the bottom plate are bonded together by hot melt, but as shown in Patent Document 2, it becomes the outer surface side of the doubled face plates. With respect to the face plate, the center part of the edge opposite to the fold ruled on the side plate side is used as a knob, and cut perforations are provided from both sides across the end portions of the fold ruled. Separate the two face plates that have been pasted together by cutting each perforation as a region that is bonded to the inner face plate that overlaps the side area with the border as the boundary and is raised from the knob. There is a device that can be used. In this way, it is considered that the closed top and bottom sides can be opened to flatten the entire storage container, which is effective in reducing dust.
Japanese Patent Laid-Open No. 05-124638 No. 07-0485505 gazette

しかしながら、上述した切り取りミシン目を二条にしたファスナを天面板に設ける構成にあっては、上位の天面板の基端（折り罫）に沿った方向で切り取りミシン目をその天面板の幅方向全長に亘って穿設する構造であるため、切り取りミシン目からなるファスナの部分の強度が大きく低下し、製函時に切り取りミシン目の位置で天面板が折れ曲がる可能性がある。また、この包装容器を持ち運ぶ際に、天面側から手を掛けて側面板の幅方向に挟み込むようにすることが考えられるが、挟み持ったときに応力が天面板の前記ファスナの部分に集中し易く、そのため、このファスナ部分で天面板が折れ曲がる可能性がある。そして、ファスナの部分を切り取ったときにそのファスナの部分が容器本体とは別の独立したゴミとなってしまう問題がある。 However, in the configuration in which the fastener having the two cut perforations is provided on the top plate, the full length of the top plate in the width direction of the top plate is cut in the direction along the base end (folding rule) of the upper top plate. Therefore, the strength of the fastener portion formed by the cut perforation is greatly reduced, and the top plate may be bent at the position of the cut perforation at the time of box making. Also, when carrying this packaging container, it is possible to hang the hand from the top side and sandwich it in the width direction of the side plate, but when it is held, stress concentrates on the fastener part of the top plate Therefore, the top plate may be bent at the fastener portion. Then, there is a problem that the portion container body of the fastener when the cut portion of the fastener becomes separate and independent dust.

また、上述したように天面側や底面側でそれぞれ上位となる面板に端縁中央からその面板の基端端部側（折り罫端部側）に向けて斜めに切り取りミシン目を穿設する技術にあっては、独立したゴミを生じる不具合は生じないが、以下の不都合の生じるものである。
上述したように外表面側となる面板の端縁に摘み部を設けているが、その摘み部が下位の面板に重なっているため、摘み部自体を摘み持つことがし難く、切り取りミシン目の間の開封始端側からの捲り起こしが簡単に行なえなくなって開封の操作が困難なものとなっている。
また、面板が折れ曲がりというつぎの不具合も生じ易いものである。即ち、斜めとした切り取りミシン目のカット目それぞれは各カット目のカット目形状が直線ではなく、全てのカット目のカット目形状がへ字形状にしていて、そのへ字形状である全てのカット目において天面板や底面板の幅方向に平行となるカット部分を有した状態となっている。
そして、この包装容器を組み起こすときに、切り取りミシン目が穿設された面板も下位の面板に重なるようにその上位の面板の基端側から折り倒すが、面板の基端側では反発が強く、基端に近い切り取りミシン目におけるカット目のその基端方向に沿ったカットの位置で応力が集中して面板が折れ曲がってしまうという不良が発生し易い。 Further, as described above, a perforation is cut out obliquely from the center of the edge to the base end side (folded crease end side) of the face plate on the upper face plate and the upper face plate respectively. In the technology, there is no inconvenience that causes independent garbage, but the following inconvenience occurs.
As described above, there is a knob on the edge of the face plate on the outer surface side, but since the knob overlaps the lower face plate, it is difficult to hold the knob itself, and the perforation In the meantime, it is difficult to lift up from the opening start side in the middle, and the opening operation is difficult.
Further, the following problem that the face plate is bent is likely to occur. That is, each cut perforated cut diagonally has a cut shape of each cut that is not a straight line. The eye has a cut portion that is parallel to the width direction of the top plate and the bottom plate.
When the packaging container is assembled, the face plate with the cut perforation is also folded from the base end side of the upper face plate so as to overlap the lower face plate, but the repulsion is strong on the base end side of the face plate. In the cut perforation near the base end, a failure that the face plate is bent due to stress concentration at the cut position along the base end direction of the cut is likely to occur.

上記切り取りミシン目に係る不具合を無くすためには、カット目全てのカット目形状を直線形状とすればよいが、しかしこれでは、切り取りミシン目が切断されたことで切断縁の形状が直線状となってしまい、特に包材が固い段ボールとしているため、開放後に内容器を取り出す作業をしているときや、収納容器を潰す作業をしているときに、鋭い形状となっている切断縁に指先などがぶつかって怪我を負う可能性がある。
そこで本発明は上記事情に鑑み、包装容器の天面や底面で二重に重ね合わされた天面の内、上位で外側となる面板に、その面板の基端とは反対側となる端縁の中央側から基端両端側に向けてそれぞれ切り取りミシン目が穿設されているものにおいて、その面板が二重に重ね合わされている部分から開封するに際して、開封の操作を開始し易くして、包装容器の取り扱いを容易にすることを課題とし、適正に製函されて、面板が二重に重ね合わせして貼り合わされている天面や底面の開放が簡単で確実に行なえる包装容器を得ることを目的とするものである。 In order to eliminate the problems related to the cut perforations, it is only necessary to make all the cut lines have a straight line shape.However, in this case, the cut edge is cut and the shape of the cutting edge is linear. In particular, because the packaging material is made of hard corrugated cardboard, when you are working to take out the inner container after opening or crushing the storage container, your fingertip will There is a risk of injury.
Therefore, in view of the above circumstances, the present invention has a top plate that is doubly stacked on the top and bottom surfaces of the packaging container. In the case where perforations are perforated from the center side toward the both ends of the base end, when opening from the portion where the faceplate is overlapped, the opening operation can be easily started and the packaging The purpose is to make the container easy to handle, and to obtain a packaging container that can be opened properly and can be opened easily and reliably, with the top and bottom surfaces of the face plates being double stacked and bonded. It is intended.

（天面部）
天面部ａにおいて、上述したように外天面板８と内天面板７とは、その側面板５の幅方向に沿った寸法が略同寸とされていて、重ね合わせ下位となる内天面板７の全面を前記外天面板８が覆っている。
さらに、外天面板８には、該外天面板８の正面板３側の折り罫１１とは反対側の端縁１２の中央の二ヶ所に切り欠き１３を入れてその間に摘み部１４が形成されている（図４参照）。 (Top)
In the top surface portion a, as described above, the outer top surface plate 8 and the inner top surface plate 7 have substantially the same dimension along the width direction of the side surface plate 5, and the inner top surface plate 7, which is the lower layer of superposition. Is covered with the outer top plate 8.
Further, the outer top plate 8 has a notch 13 formed at two positions in the center of the edge 12 on the side opposite to the crease 11 on the front plate 3 side of the outer top plate 8 and a knob 14 is formed therebetween. (See FIG. 4).

上記摘み部１４の両側の前記切り欠き１３からは、外天面板８の正面板３側の前記折り罫１１の端部に亘る二本の切り取りミシン目１５が入れられている。切り取りミシン目１５については後述する。そして、外天面板８が、二本の切り取りミシン目１５を境にしてこの切り取りミシン目１５の間となる引き起こし領域１６と、切り取りミシン目１５から外天面板８の幅方向での側方にしている固定領域１７とに区分される。前記固定領域１７は、外天面板８との重ね合わせ下位となっている内天面板７に貼り合わされている領域であり、外天面板８の固定領域１７と内天面板７の対応部分とのホットメルトなどの接着剤を介した貼り合わせで外天面板８と内天面板７とが一体となっている。
このように、切り取りミシン目１５を境とした側方側に位置する上記固定領域１７の部分のみが内天面板７に貼り合わされているため、上記摘み部１４の部分を持って引き起こすことにより、上記切り取りミシン目１５それぞれが切断し、この切断により固定領域１７を内天面板７側に残存させて引き起こし領域１６のみとなった外天面板８が内天面板７から分離させることができるように設けられている。 Two cut perforations 15 extending from the notches 13 on both sides of the knob 14 to the end of the crease 11 on the front plate 3 side of the outer top plate 8 are provided. The cut perforation 15 will be described later. Then, the outer top plate 8 is located between the cut perforations 15 at the boundary between the two cut perforations 15 and from the cut perforations 15 to the side in the width direction of the outer top plate 8. The fixed area 17 is divided. The fixed region 17 is a region bonded to the inner top plate 7 that is the lower layer of the outer top plate 8, and the fixed region 17 of the outer top plate 8 and the corresponding portion of the inner top plate 7 The outer top surface plate 8 and the inner top surface plate 7 are integrated by bonding through an adhesive such as hot melt.
In this way, since only the portion of the fixed region 17 located on the lateral side with the cut perforation 15 as a boundary is bonded to the inner top plate 7, by causing the knob portion 14 to be held, Each of the cut perforations 15 is cut, and the cutting causes the fixed region 17 to remain on the inner top plate 7 side so that the outer top plate 8 having only the region 16 can be separated from the inner top plate 7.

（切り取りミシン目）
外天面板８と外底面板１０との上記切り取りミシン目１５について説明する。
上記摘み部１４の端縁１２とこの端縁から上記切り欠き１３を経て切り取りミシン目１５と連続する切り込み部分までの範囲において、それぞれの形状が波形のピッチを小さく波形の凹凸の大きさが小さい波線形状に形成されていて、上述した摘み部１４が引き起こされたときにその摘み部１４の端縁１２や切り欠き１３を構成していた端縁、そして切り取りミシン目１５に連続している部分に手や指先が当たっても怪我を負うことがないようにしている。
そして、前記切り取りミシン目１５それぞれにあっては、上記切り欠き１３側の上記波線形状の切り込み部分に連続する位置（一個のカット目）と正面板３の折り罫１１の端部側に位置する直線カット目部２３と、この直線カット目部２３の間にあって直線カット目部２３に連続する屈曲カット目部２４とからなるものである。
上記直線カット目部２３は、カット目形状を直線形状のみにして切り取りミシン目全体の傾斜方向にそのカットが沿うようにしたものであり、屈曲カット目部２４は、それぞれのカット目形状をへ字形状にしたものであって、前記屈曲カット目部２４のカット目それぞれは、切り取りミシン目１５全体の傾斜方向に沿ったカットと引き起こし領域の中心側に向いて折り罫１１にほぼ平行としたカットとが連続しているものである。
このように、摘み部１４側において直線カット目部２３が設けられているため、その摘み部１４を持って引き起こす際に切り取りミシン目１５の切り欠き側から切断の始端が簡単に生じ、その切断がスムーズに進むようになる。また、折り罫１１の端部側を直線カット目部２３としているため、製函に際して外天面板８や外底面板１０を折り曲げても切り取りミシン目１５自体に、包材の反発による応力が集中することがなく、よって、外天面板８や外底面板１０が適正に曲げられるようになり、適正に製函された包装容器１が得られる。
図４において外天面板８での切り取りミシン目１５を図示したが、上述しているように外底面板１０での切り取りミシン目１５も同一の構成を有する。 (Cut perforation)
The cut perforation 15 of the outer top plate 8 and the outer bottom plate 10 will be described.
In the range from the edge 12 of the knob 14 and the edge to the cut portion that continues through the notch 13 and the cut perforation 15, each shape has a smaller waveform pitch and smaller corrugated irregularities. A portion that is formed in a wavy shape and that is continuous with the cut perforation 15 and the edge that formed the edge 12 or notch 13 of the knob 14 when the knob 14 described above is raised. Even if your hand or fingertip hits, it will not injure you.
Each of the cut perforations 15 is located at a position (one cut line) continuous with the wavy line-shaped cut portion on the notch 13 side and on the end side of the crease 11 of the front plate 3. It consists of a straight cut portion 23 and a bent cut portion 24 that is between the straight cut portions 23 and continues to the straight cut portions 23.
The straight cut portion 23 is formed by cutting the cut shape into only a straight shape so that the cut extends along the inclination direction of the entire perforation. Each of the cuts of the bent cut part 24 is cut along the inclined direction of the entire cut perforation 15 and is caused to be substantially parallel to the crease 11 toward the center side of the cause area. The cut is continuous.
As described above, since the straight cut portion 23 is provided on the side of the knob portion 14, when the handle portion 14 is held, the cutting start edge is easily generated from the notch side of the cut perforation 15, and the cutting is performed. Will go smoothly. Further, since the end portion side of the crease 11 is a straight cut portion 23, even when the outer top plate 8 or the outer bottom plate 10 is folded during box making, stress due to the rebound of the packaging material is concentrated on the perforation 15 itself. Therefore, the outer top surface plate 8 and the outer bottom surface plate 10 can be appropriately bent, and the packaging container 1 appropriately boxed can be obtained.
Although the cut perforation 15 on the outer top plate 8 is illustrated in FIG. 4, the cut perforation 15 on the outer bottom plate 10 has the same configuration as described above.
