Description

この発明は、飲料缶の集合包装等に使用される包装箱であって、開梱用の引裂帯を有するものに関する。   The present invention relates to a packaging box used for collective packaging of beverage cans and the like, which has a tear strip for unpacking.

一般に、ビール等の飲料缶は、図５に示すようなラップラウンド式の段ボール製包装箱により梱包される。   Generally, beverage cans such as beer are packed in a wrap-round cardboard packaging box as shown in FIG.

この包装箱は、各一対の平面板５１及び側面板５２を筒状に連設し、側面板５２から延びる端蓋片５３と、平面板５１から延びる端蓋板５４とを貼り合わせて端面を閉じ、側面板５２から端蓋片５３にかけて裏面側のライナを切断した引裂帯５５を設け、その切始部５６を側面板５２の中間部に切目を入れて形成したものである。   In this packaging box, each pair of the flat plate 51 and the side plate 52 are connected in a cylindrical shape, and the end cover piece 53 extending from the side plate 52 and the end cover plate 54 extending from the flat plate 51 are bonded to each other. A tear band 55 is formed by closing and cutting the liner on the back side from the side plate 52 to the end lid piece 53, and the cut start portion 56 is formed in the middle portion of the side plate 52.

このような包装箱では、切始部５６から引裂帯５５を引っ張って、側面板５２及び端蓋片５３を切断すると、箱体が上下に分割されるので、その上半部を除去して、トレー状となった下半部から露出する飲料缶を店頭で陳列することができる。   In such a packaging box, by pulling the tear strip 55 from the cut start portion 56 and cutting the side plate 52 and the end cover piece 53, the box body is divided into upper and lower parts, so the upper half is removed, Beverage cans exposed from the lower half of the tray can be displayed at the store.

ところが、この開梱に際し、引裂帯５５を勢いよく引っ張ると、角張った側面板５２と端蓋板５３との境界で引裂帯５５が千切れてしまい、所定の手順で開梱できなくなることがあった。   However, if the tear strip 55 is pulled vigorously at the time of unpacking, the tear strip 55 may be cut off at the boundary between the square side plate 52 and the end cover plate 53 and may not be opened in a predetermined procedure. It was.

このため、下記特許文献１においては、図６に示すように、一対の切始部５６を端部側へ寄せて、その間に切目線５７を入れておき、引裂帯５５の長さを短縮することにより、引裂帯５５を引っ張る勢いを抑制して、引裂帯５５の千切れを防止しようとするものが提案されている。   For this reason, in the following Patent Document 1, as shown in FIG. 6, the pair of cut start portions 56 are moved toward the end portion, and a cut line 57 is put between them to shorten the length of the tear band 55. Thus, there has been proposed an apparatus that suppresses the momentum of pulling the tear band 55 and prevents tearing of the tear band 55.

特開２００４−１５５４７８号公報JP 2004-155478 A

しかしながら、図６に示す包装箱では、引裂帯５５の千切れ防止効果が不十分であるだけでなく、段ボールを貫通する長い切目線５７が側面板５２の中間部に入れられているため、側面板５２の強度が低下し、輸送時や保管時に積上荷重が作用すると、側面板５２が座屈して変形するおそれがあった。   However, in the packaging box shown in FIG. 6, not only the effect of preventing the tear strip 55 from being broken is insufficient, but also a long score line 57 penetrating the cardboard is placed in the middle part of the side plate 52, If the strength of the face plate 52 is reduced and a loading load is applied during transportation or storage, the side plate 52 may be buckled and deformed.

そこで、この発明は、引裂帯が千切れることなく、確実に開梱でき、積上荷重に対する強度も低下しない包装箱を提供することを課題とする。   Then, this invention makes it a subject to provide the packaging box which can be unpacked reliably without tearing a tear band, and the intensity | strength with respect to a load is not reduced.

上記課題を解決するため、この発明は、各一対の平面板及び側面板を筒状に連設し、側面板から延びる端蓋片と、平面板から延びる端蓋板とを貼り合わせて端面を閉じ、側面板から端蓋片にかけて引裂帯を設け、引裂帯の切始部を側面板に形成した包装箱において、平面板の四隅を膨出弧状に切断し、側面板と端蓋片との境界部分に、平面板の弧状縁に沿って順次折れ曲がるように複数条の罫線を入れて曲面部を形成したのである。   In order to solve the above-described problems, the present invention is configured such that each pair of flat plate and side plate is connected in a cylindrical shape, and an end cover piece extending from the side plate and an end cover plate extending from the flat plate are bonded together to form an end face. Closed, provided a tear strip from the side plate to the end cover piece, and cut the four corners of the flat plate into a bulging arc shape in the packaging box in which the start portion of the tear band was formed on the side plate. A curved surface portion was formed by putting a plurality of ruled lines at the boundary portion so as to bend sequentially along the arc-shaped edge of the flat plate.

また、前記曲面部に、引裂帯に沿ってハの字状の切目を断続的に入れ、手前の切目の先端よりも次の切目の基端が引裂帯の内側に位置するようにしたのである。   In addition, the curved section is intermittently cut along the tear strip, so that the base end of the next cut is positioned inside the tear strip from the front of the front cut. .

この包装箱では、側面板と端蓋片との境界部分に曲面部を形成したので、引裂帯を側面板から端蓋片へスムーズに回り込むように引っ張ることができ、引裂帯の千切れが防止され、開梱作業を容易に行うことができる。また、側面板に表裏に貫通する長い切目線を入れる必要がないので、積上荷重に対する強度も確保される。   In this packaging box, a curved surface is formed at the boundary between the side plate and the end cover piece, so the tear band can be pulled smoothly from the side plate to the end cover piece, preventing tearing of the tear band. Thus, unpacking can be easily performed. Moreover, since it is not necessary to make a long score line penetrating the front and back of the side plate, the strength against the load is ensured.

また、前記曲面部に、引裂帯に沿ってハの字状の切目を断続的に入れ、手前の切目の先端よりも次の切目の基端を内側に位置させると、引裂帯の千切れをさらに確実に防止することができる。   In addition, when the C-shaped cut is intermittently made along the tear band in the curved surface portion and the base end of the next cut is positioned inside the front end of the front cut, the tear band is cut off. Furthermore, it can prevent reliably.

以下、この発明の実施形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１に示すように、この包装箱の段ボール製ブランクでは、各一対の平面板１及び側面板２が交互に連設され、一方の側面板２の外側には継代片３が連設されている。各側面板２の両端には端蓋片４が、平面板１の両端には端蓋板５がそれぞれ連設されている。   As shown in FIG. 1, in the cardboard blank of this packaging box, each pair of flat plates 1 and side plates 2 are alternately connected, and a passage piece 3 is continuously provided outside one side plate 2. ing. End cover pieces 4 are connected to both ends of each side plate 2, and end cover plates 5 are connected to both ends of the flat plate 1, respectively.

平面板１の四隅は、膨出弧状に切断され、側面板２と端蓋片４の境界部分には、平行な複数条の罫線６を幅方向に入れて、曲面部７をなす部分が形成されている。   The four corners of the flat plate 1 are cut into a bulging arc shape, and at the boundary portion between the side plate 2 and the end cover piece 4, a plurality of parallel ruled lines 6 are inserted in the width direction to form a curved surface portion 7. Has been.

側面板２、曲面部７及び端蓋片４には、裏側のライナを切断して引裂帯８が形成され、その切始部９が側面板２の中間部に切目を入れて形成されている。 The side plate 2, the curved surface portion 7, and the end cover piece 4 are formed by cutting the liner on the back side to form a tear strip 8, and the cut start portion 9 is formed by making a cut in the middle portion of the side plate 2. .

曲面部７には、引裂帯８に沿ってハの字状の切目１０が断続的に入れられ、手前の切目１０の先端よりも次の切目１０の基端が引裂帯８の内側に位置するようになっている。   A C-shaped cut 10 is intermittently made in the curved surface portion 7 along the tear band 8, and the proximal end of the next cut 10 is located inside the tear band 8 from the tip of the front cut 10. It is like that.

このような包装箱により飲料缶を梱包する際には、図２に示すように、各一対の平面板１及び側面板２を角筒状に折り曲げて、継代片３を反対側の平面板１の内面に貼り付け、端蓋片４と端蓋板５とを貼り合わせて端面を閉止する。   When packing a beverage can with such a packaging box, as shown in FIG. 2, each pair of plane plate 1 and side plate 2 is bent into a rectangular tube shape, and the passage piece 3 is placed on the opposite plane plate. The end cover piece 4 and the end cover plate 5 are bonded together to close the end face.

このとき、平面板１の四隅の弧状縁に沿って、罫線６の作用により曲面部７が順次折れ曲がり、箱の四隅の稜部に丸みが付けられる。   At this time, along the arcuate edges at the four corners of the flat plate 1, the curved surface portion 7 is sequentially bent by the action of the ruled lines 6, and the ridges at the four corners of the box are rounded.

上記包装箱では、開梱に際し、図３に示すように、切始部９を起点に、引裂帯８を側面板２から端蓋片４へスムーズに回り込むように引っ張ることができ、また、隣接する切目１０の間に生じる裂目が途切れることがなく繋がるので、箱体の稜部における引裂帯８の千切れが防止され、開梱作業を容易に行うことができる。 In the above package box, upon unpacking, as shown in FIG. 3, the starting point SetsuHajime portion 9, it is possible to pull the tear strip 8 to go around smoothly from the side plate 2 to Tanfutahen 4, also, the adjacent Since the crevices generated between the cuts 10 are connected without interruption, tearing of the tear band 8 at the ridge portion of the box is prevented, and the unpacking operation can be easily performed.

また、側面板２に、表裏に貫通する長い切目線を入れる必要がないので、積上荷重に対する強度も確保される。   Moreover, since it is not necessary to make the side plate 2 have a long score line penetrating the front and back, the strength against the load is ensured.

そして、このように側面板２及び端蓋板４を切断して、箱体を上下に分割すると、図４に示すように、箱体の上半部を除去して、トレー状となった下半部から露出する飲料缶Ｃを店頭で陳列することができる。   And when the side plate 2 and the end cover plate 4 are cut in this way and the box body is divided into upper and lower parts, as shown in FIG. The beverage can C exposed from the half can be displayed at the store.
