Description

本発明は、例えば貼付剤等の商品を包装するための包装用箱に関する。   The present invention relates to a packaging box for packaging a product such as a patch.

従来より、商品の包装用容器として、紙、例えば段ボール紙やコートボール紙から構成された包装用箱が広く使用されている。また、店頭で商品を販売する際、上部を切除して展示箱としても使用できるようにした包装用箱も知られている。   2. Description of the Related Art Conventionally, packaging boxes made of paper, such as corrugated cardboard or coated cardboard, have been widely used as packaging containers for merchandise. A packaging box is also known in which, when products are sold at a store, the upper part is cut off so that it can be used as an exhibition box.

かかる展示箱兼用の包装用箱には、前面部の上下方向中央部に形成された水平の第１の切込み線（いわゆるミシン目）と、各側面部に形成され、第１の切込み線の端部から側面部の後端縁の上端部まで斜め上方に延びる第２の切込み線と、後面部の上縁に沿って形成された第３の切込み線とを備えるものがある。第１〜第３の切込み線に沿って包装用箱を切断し開封すると、下部部分が展示箱として機能する。側面部の切込み線を斜めとしているのは、美観が良いことに加え、側方からの商品（特にパップ剤のような貼付剤等の薄手の商品）の取出しが容易となるためである。   Such a packaging box also serving as a display box has a horizontal first cut line (a so-called perforation) formed at the center in the vertical direction of the front surface portion and an end of the first cut line formed at each side surface portion. Some have a second cut line extending obliquely upward from the upper part to the upper end of the rear end edge of the side surface part, and a third cut line formed along the upper edge of the rear surface part. When the packaging box is cut and opened along the first to third cut lines, the lower part functions as an exhibition box. The reason why the cut line on the side surface is slanted is that, in addition to good aesthetics, it is easy to take out products from the side (particularly thin products such as patches such as poultices).

ところで、上述したような型式の包装用箱には、開封をより容易化するために、前面部の第１の切込み線が上下２本とされたもの（特許文献１参照）や、第１の切込み線のみならず第２の切込み線も上下２本とされたもの（特許文献２参照）がある。これらは、上下の切込み線間の部分を開封片として用い、この開封片を指で把持して引っ張ることで、切断を容易に行うようにしたものである。   By the way, in the type of packaging box as described above, in order to make the opening easier, the first incision line on the front portion is two upper and lower (see Patent Document 1), the first There is a structure in which not only the cutting line but also the second cutting line are two vertically (see Patent Document 2). In these cases, the portion between the upper and lower cut lines is used as an opening piece, and the opening piece is grasped with a finger and pulled, so that cutting is easily performed.

特許文献１に記載の包装用箱の場合、前面部の開封片を切除した後は、その切除部分に指を差し込み、包装用箱の上部部分を引き上げて、側面部を第２の切込み線に沿って切断する。   In the case of the packaging box described in Patent Document 1, after excising the unsealed piece on the front part, insert a finger into the excised part, pull up the upper part of the packaging box, and use the side part as the second score line. Cut along.

特許文献２に記載の包装用箱の場合、前面部のみならず左右の側面部にも開封片が形成されているため、開封片を引き剥がすことで、前面部から側面部までの切断を一気に行うことが可能である。
特開平１１−７９１６６号公報 特開２００２−２６８５号公報 In the case of the packaging box described in Patent Document 2, since the opening pieces are formed not only on the front surface portion but also on the left and right side portions, the cutting from the front surface portion to the side surface portion can be performed at once by peeling off the opening pieces. Is possible.
JP-A-11-79166 Japanese Patent Laid-Open No. 2002-2585

しかしながら、特許文献１に記載の包装用箱においては、開封片は前面部のみに形成されているため、開封片の除去部分を指で引き上げようとした際、前面部と側面部との角（二面交差部）で裂け、第２の切込み線に沿って切断されないことがある。かかる場合、再度、第２の切込み線に沿って包装用箱を切断する必要があり、手間がかかる。   However, in the packaging box described in Patent Document 1, since the opening piece is formed only on the front surface portion, when the removal portion of the opening piece is to be pulled up with a finger, the corner between the front surface portion and the side surface portion ( It may tear at the two-surface intersection) and may not be cut along the second cut line. In such a case, it is necessary to cut the packaging box along the second cut line again, which is troublesome.

また、特許文献２に記載の包装用箱においては、前面部の開封片を適正に切除することができたとしても、側面部の開封片を切除しようとした際、開封片に隣接する表面層が剥がれ、美観を損ね、展示箱としての機能を果たさなくなるおそれがある。   Further, in the packaging box described in Patent Document 2, even if the opening piece on the front surface portion can be appropriately excised, the surface layer adjacent to the opening piece when attempting to excise the opening piece on the side surface portion. May peel off, detract from aesthetics, and may not function as an exhibition box.

本発明の目的は、上記従来における問題点を解決することのできる包装用箱を提供することにある。   An object of the present invention is to provide a packaging box that can solve the above-mentioned conventional problems.

上記目的を達成するために、本発明者らは鋭意検討した結果、特許文献１に記載の包装用箱において、平面状の側面部を上下から引っ張って切込み線に沿って裂くよりも、前面部を持ち上げて前面部と側面部との角で裂く方が力がかからない場合があることを見出した。   In order to achieve the above object, the present inventors have intensively studied, and as a result, in the packaging box described in Patent Document 1, the front side portion is formed by pulling the planar side portion from above and below and tearing it along the cut line. It has been found that there is a case where force is not applied when lifting and tearing at the corners of the front and side portions.

一方、特許文献２に記載の包装用箱の上記問題は、包装用箱を形成している紙に繊維の方向があることに起因すると考えた。すなわち、前面部の水平の開封片を適正に切除できるようにするには、包装用箱の前面部における紙の繊維方向を略水平に向ける必要がある。そのような向きとした場合、通常、包装用箱の側面部における繊維方向も略水平となるが、側面部の開封片は斜めに形成されているため、側面部の開封片を切除する際、切込み線の繋ぎ目部分（ミシン目の細線孔間の部分）が繊維方向に切裂しようとし、それが表面層の剥離となるのである。   On the other hand, the above problem of the packaging box described in Patent Document 2 was thought to be due to the direction of the fibers in the paper forming the packaging box. That is, in order to properly cut the horizontal opening piece on the front face, it is necessary to orient the paper fiber direction on the front face of the packaging box substantially horizontally. When such an orientation, usually the fiber direction in the side portion of the packaging box is also substantially horizontal, but the opening piece of the side portion is formed obliquely, when cutting off the opening piece of the side portion, The joint part of the incision line (the part between the fine line holes of the perforation) tries to tear in the fiber direction, and this becomes peeling of the surface layer.

本発明は上記知見に基づいてなされたものであり、前面部と、この前面部の左右の各端縁に連設された側面部と、左右の側面部の後端縁間を繋ぐ後面部と、上部開口を閉じる上面部と、底部開口を閉じる底面部とを備える包装用箱において、前面部に水平に形成された上下２本の第１の切込み線と、第１の切込み線のそれぞれの各端部から水平に延びるよう、側面部のそれぞれに形成された上下２本の第２の切込み線であって、側面部の後端縁に至る前で終端している前記第２の切込み線と、第２の切込み線の後端部から側面部の後端縁まで斜め上方に延びる傾斜切込み線と、左右の傾斜切込み線の後端部間を繋ぐ第３の切込み線とを備えることを特徴としている。   The present invention has been made on the basis of the above findings, and includes a front surface portion, a side surface portion connected to the left and right end edges of the front surface portion, and a rear surface portion connecting between rear end edges of the left and right side surface portions. In the packaging box comprising a top surface portion that closes the top opening and a bottom surface portion that closes the bottom opening, each of the first and second cut lines formed vertically on the front face portion and the first cut line The upper and lower second cut lines formed in each of the side surface parts so as to extend horizontally from the respective end parts, the second cut line terminating before reaching the rear edge of the side surface part. And an inclined cut line extending obliquely upward from the rear end portion of the second cut line to the rear end edge of the side surface portion, and a third cut line connecting the rear end portions of the left and right inclined cut lines. It is a feature.

前述したような本発明による包装用箱においては、側面部に形成される上下１対の第２の切込み線も第１の切込み線と同様に水平に延びているため、切込み線間の開封片の切除を容易に行うことができ、また、紙の繊維方向に沿って切断できることから、開封片に隣接する部分の表面層剥離も防止することができる。   In the packaging box according to the present invention as described above, the pair of upper and lower second cut lines formed on the side surface portion also extend horizontally in the same manner as the first cut line, and therefore the opening piece between the cut lines. Can be easily cut out, and since it can be cut along the fiber direction of the paper, peeling of the surface layer of the portion adjacent to the opening piece can also be prevented.

また、本発明では、側面部の傾斜切込み線の始点が第２の切込み線の後端部となっている。すなわち、傾斜切込み線の始点は側面部の中央部にあることから、開封時、側面部に引張り力を作用させると、確実に傾斜切込み線に沿って側面部を切断することができる。   In the present invention, the starting point of the inclined cut line on the side surface portion is the rear end portion of the second cut line. That is, since the starting point of the inclined cut line is at the center of the side surface portion, when the tensile force is applied to the side surface portion at the time of opening, the side surface portion can be reliably cut along the inclined cut line.

よって、本発明による包装用箱は、開封が容易であり、開封後の美観にも優れ展示箱としても良好なものとなる。   Therefore, the packaging box according to the present invention can be easily opened, has an excellent aesthetic appearance after opening, and is a good display box.

以下、図面に沿って本発明の最良の実施形態について詳細に説明する。   Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings.

図１は、本発明による包装用箱を示す斜視図であり、図２は、開封状態を示す同包装用箱の斜視図である。この包装用箱１０は、１枚の厚紙、好ましくは展示箱としての美観的効果を奏することのできるコートボール紙から作られている。   FIG. 1 is a perspective view showing a packaging box according to the present invention, and FIG. 2 is a perspective view of the packaging box showing an opened state. The packaging box 10 is made of a single cardboard, preferably coated cardboard that can provide an aesthetic effect as an exhibition box.

図１に示すように、包装用箱１０は直方体形状をなし、矩形の底面部１２と、この底面部１２の各長縁から垂直上方に延びる前面部１４及び後面部１６と、底面部１２の各短縁から垂直上方に延び且つ前面部１４及び後面部１６の対応端縁間を連結する左右の側面部１８，２０と、前面部１４、後面部１６及び側面部１８，２０の上縁が画す上部開口を閉じる上面部２２とから構成されている。なお、本明細書及び添付の特許請求の範囲において「水平」、「垂直」、「上」、「下」等の方向を表す語は、図１の包装用箱１０を水平面に置いた時の状態を基準としている。   As shown in FIG. 1, the packaging box 10 has a rectangular parallelepiped shape, a rectangular bottom surface portion 12, a front surface portion 14 and a rear surface portion 16 extending vertically upward from each long edge of the bottom surface portion 12, and a bottom surface portion 12. Left and right side surfaces 18 and 20 that extend vertically upward from each short edge and connect corresponding end edges of the front surface portion 14 and the rear surface portion 16, and upper edges of the front surface portion 14, the rear surface portion 16, and the side surface portions 18 and 20 The upper surface part 22 which closes the upper opening to demarcate is comprised. In the present specification and the appended claims, the terms such as “horizontal”, “vertical”, “upper”, “lower” and the like are directions when the packaging box 10 of FIG. 1 is placed on a horizontal plane. Based on state.

図３は、かかる包装用箱１０の展開図であり、矩形部分２４は包装用箱１０の前面部１４を構成し、その左右両側に連設される矩形部分２６，２８はそれぞれ左右の側面部１８，２０を構成する。また、左側の矩形部分２６に連設される矩形部分３０は後面部１６を構成するものである。矩形部分３０の左側に続く部分３２は継ぎ代であり、これを右側の矩形部分２８に接着剤等により接合することで、矩形部分２４〜３０は角筒状となる。各矩形部分２４〜３０の下縁に連接される各部分３４，３６，３８，４０を組み合わせることで、包装用箱１０の底部開口を閉じる底面部１２をなす。また、側面部１８，２０となる矩形部分２６，２８の上縁から延びる部分４２，４４はいわゆる内フラップであり、前面部１４及び後面部１６となる矩形部分２４，３０の上縁から延びる部分４６，４８はいわゆる外フラップである。内フラップ４２，４４及び外フラップ４６，４８を折り曲げ、内フラップ４２，４４の上に外フラップ４６，４８を重ねて接着剤等で互いに接合することで、包装用箱１０の上面部２２が形成される。   FIG. 3 is an exploded view of the packaging box 10, wherein the rectangular portion 24 constitutes the front portion 14 of the packaging box 10, and the rectangular portions 26 and 28 provided on the left and right sides thereof are the left and right side portions, respectively. 18 and 20 are configured. Further, the rectangular portion 30 connected to the left rectangular portion 26 constitutes the rear surface portion 16. A portion 32 continuing to the left side of the rectangular portion 30 is a joint, and the rectangular portions 24 to 30 are formed in a rectangular tube shape by joining the portion 32 to the right rectangular portion 28 with an adhesive or the like. By combining the portions 34, 36, 38, and 40 connected to the lower edges of the rectangular portions 24 to 30, the bottom surface portion 12 that closes the bottom opening of the packaging box 10 is formed. Further, the portions 42 and 44 extending from the upper edges of the rectangular portions 26 and 28 which become the side portions 18 and 20 are so-called inner flaps, and the portions extending from the upper edges of the rectangular portions 24 and 30 which become the front surface portion 14 and the rear surface portion 16. 46 and 48 are so-called outer flaps. The inner flaps 42 and 44 and the outer flaps 46 and 48 are bent, and the outer flaps 46 and 48 are overlapped on the inner flaps 42 and 44 and joined together with an adhesive or the like, thereby forming the upper surface portion 22 of the packaging box 10. Is done.

本実施形態に係る包装用箱１０においては、更に、その前面部１４に水平方向に延びる上下１対の切込み線（第１の切込み線）５０，５２が形成されている。これらの切込み線５０，５２間の部分５４は開封片として機能するものである。この開封片５４を水平方向に切除するために、包装用箱１０を構成する紙の繊維方向も略水平となるよう定められている。切込み線５０，５２の上下方向の間隔、すなわち開封片５４の幅は、限定的なものではないが、指でこれを摘めるよう、１cm前後であることが好ましい。また、包装される商品の形態や寸法にもよるが、商品が薄手の貼付剤等の場合、これらの切込み線５０，５２は、包装用箱１０の上下方向の略中間位置に形成することが好ましい。   In the packaging box 10 according to the present embodiment, a pair of upper and lower cut lines (first cut lines) 50 and 52 extending in the horizontal direction are further formed on the front surface portion 14. A portion 54 between the cut lines 50 and 52 functions as an opening piece. In order to cut off the opening piece 54 in the horizontal direction, the fiber direction of the paper constituting the packaging box 10 is also determined to be substantially horizontal. The vertical distance between the cut lines 50 and 52, that is, the width of the unsealed piece 54 is not limited, but is preferably about 1 cm so that it can be grasped with a finger. Depending on the form and size of the product to be packaged, when the product is a thin patch or the like, these cut lines 50 and 52 may be formed at a substantially intermediate position in the vertical direction of the packaging box 10. preferable.

左右の各側面部１８，２０にも、前面部１４における各切込み線５０，５２から一直線状に延びるよう、水平の切込み線（第２の切込み線）５６，５８が形成されている。各側面部１８，２０における切込み線５６，５８は、当該側面部１８，２０の後端縁に至る手前の適当な位置、例えば前後方向の略中間位置にて終端している。   Horizontal cut lines (second cut lines) 56 and 58 are also formed on the left and right side faces 18 and 20 so as to extend straight from the cut lines 50 and 52 in the front face part 14. The cut lines 56 and 58 in the side surfaces 18 and 20 terminate at an appropriate position before reaching the rear edge of the side surfaces 18 and 20, for example, a substantially intermediate position in the front-rear direction.

このように、本実施形態における包装用箱１０の前面部１４及び左右の側面部１８，２０には、連続する上下１対の切込み線５０，５６；５２，５８が形成され、図３から理解される通り、これらの上下の切込み線５０，５６；５２，５８の間の部分５４，６０，６２が、直線状の１本の開封片として機能するようになっている。当該開封片５４，６０，６２は、左側の側面部１８から前面部１４、そして右側の側面部２０にかけて、或いはその逆の方向に、包装用箱１０から切除することが可能であるが、本実施形態では、右利きの人間による開封片切除作業の利便性を考慮して、左側の側面部１８からの切除を容易とする形状に切込み線５０，５２，５６，５８が形成されている。また、図３に示すように、左側の側面部１８における切込み線５６，５８の終端部分５６ａ，５８ａは、間隔の小さなミシン目とされ、且つ、上下を繋ぐ縦のミシン目６４が形成されている。これは、指を軽い力で切込み線５６，５８間に押し入れて開封片６０の端部を摘めるようにするためである。   As described above, the front portion 14 and the left and right side portions 18 and 20 of the packaging box 10 in the present embodiment are formed with a pair of continuous upper and lower cut lines 50, 56; 52, 58, which are understood from FIG. As shown, the portions 54, 60, 62 between the upper and lower cut lines 50, 56; 52, 58 function as one straight opening piece. The opening pieces 54, 60, 62 can be cut from the packaging box 10 from the left side surface portion 18 to the front surface portion 14 and the right side surface portion 20, or vice versa. In the embodiment, the cutting lines 50, 52, 56, and 58 are formed in a shape that facilitates excision from the left side surface portion 18 in consideration of the convenience of opening piece excision work by a right-handed person. Further, as shown in FIG. 3, the end portions 56a and 58a of the cut lines 56 and 58 in the left side surface portion 18 are perforations with a small interval, and vertical perforations 64 that connect the top and bottom are formed. Yes. This is because the end of the opening piece 60 can be grasped by pushing the finger between the cut lines 56 and 58 with a light force.

左右の側面部１８，２０には、上側の切込み線５６の末端から、当該側面部１８，２０の後端縁６５の上部、好ましくは側面部１８，２０、後面部１６及び上面部２２の交点６６まで斜め上方に延びる傾斜切込み線６８が１本形成されている。この傾斜切込み線６８は通常のミシン目である。更に、後面部１６と上面部２２との角に沿って、すなわち左右の傾斜切込み線６８の上端間にも、切込み線（第３の切込み線）７０が形成されている。この切込み線７０も通常のミシン目である。   On the left and right side surfaces 18 and 20, from the end of the upper cut line 56, the upper portion of the rear edge 65 of the side surface portions 18 and 20, preferably the intersection of the side surface portions 18 and 20, the rear surface portion 16, and the upper surface portion 22. One inclined cut line 68 extending obliquely upward to 66 is formed. The inclined cut line 68 is a normal perforation. Further, a cut line (third cut line) 70 is formed along the corner between the rear surface portion 16 and the upper surface portion 22, that is, between the upper ends of the left and right inclined cut lines 68. This cut line 70 is also a normal perforation.

このような構成の包装用箱１０を開封する場合、まず、左側の側面部１８における切込み線５６，５８の終端部分５６ａ，５８ａ間に指を押し込む。これによりミシン目５６ａ，５８ａ，６４が裂け、開封片６０の端部を摘むことが可能となる。この後、開封片６０を引っ張り、左側の側面部１８から前面部１４を経て右側の側面部２０へと開封片６０，５４，６２を連続的に切除する。開封片５４，６０，６２を形成している切込み線５０，５２，５６，５８は前面部１４でも側面部１８，２０でも水平に延び、また、包装用箱１０を構成している紙の繊維方向も略水平に向けられているため、包装用箱１０の表面層が剥離することなく、開封片５４，６０，６２をきれいに切除することが可能となる。   When opening the packaging box 10 having such a configuration, first, a finger is pushed between the end portions 56 a and 58 a of the cut lines 56 and 58 in the left side surface portion 18. As a result, the perforations 56a, 58a, 64 are torn and the end of the opening piece 60 can be picked. Thereafter, the opening piece 60 is pulled, and the opening pieces 60, 54, and 62 are continuously cut from the left side surface portion 18 through the front surface portion 14 to the right side surface portion 20. The cut lines 50, 52, 56, and 58 forming the opening pieces 54, 60, and 62 extend horizontally in both the front surface portion 14 and the side surface portions 18 and 20, and the paper fibers constituting the packaging box 10. Since the direction is also oriented substantially horizontally, it is possible to cleanly cut the opening pieces 54, 60, 62 without peeling off the surface layer of the packaging box 10.

開封片５４，６０，６２が切除されたならば、その切除部分に指を差し入れ、前面部１４の上部部分を上方に引き上げる。これにより、側面部１８，２０の上部部分には上方への引張り力が作用し、傾斜切込み線６８に沿って側面部１８，２０が上下に切断される。この際、平面状の側面部１８，２０に、傾斜切込み線６８を境にして相反する引張り力を作用させることになるが、傾斜切込み線６８上の部分以外の部分は強度が高く、切断は傾斜切込み線６８に沿って確実に行われる。   When the opening pieces 54, 60, 62 are excised, a finger is inserted into the excised portion, and the upper portion of the front face 14 is pulled upward. As a result, an upward tensile force acts on the upper portions of the side surface portions 18 and 20, and the side surface portions 18 and 20 are cut up and down along the inclined cut line 68. At this time, opposite tensile forces are applied to the planar side portions 18 and 20 with the inclined cut line 68 as a boundary, but the portion other than the portion on the inclined cut line 68 has high strength, and the cutting is not performed. It is performed reliably along the inclined cut line 68.

最後に、後面部１６と上面部２２との間の切込み線７０に沿って包装用箱１０の上部部分を切り取る。この状態が図２に示す状態である。図２に示す開封状態の包装用箱１０は、内部に収容された貼付剤のような商品（図示しない）の下部を支持し、また、商品と同等の高さを有する後面部１６にて商品を確実に支えることができる。これを前方から見た場合、商品の上部の大部分を見ることが可能であるので、商品の展示箱としての機能を果たすことができる。また、側面部１８，２０の前半分の高さが前面部１４と同じ高さで一定とされ、側面部１８，２０の後半分も後方にかけて漸次高くされているので、側方からの商品取出しが容易となる。更に、図２から理解される通り、美観にも優れたものとなる。   Finally, the upper portion of the packaging box 10 is cut out along the cut line 70 between the rear surface portion 16 and the upper surface portion 22. This state is the state shown in FIG. The packaging box 10 in the opened state shown in FIG. 2 supports the lower part of a product (not shown) such as a patch housed inside, and the rear surface portion 16 having the same height as the product is used for the product. Can be reliably supported. When viewed from the front, most of the upper part of the product can be seen, so that it can function as a display box for the product. Moreover, since the height of the front half of the side surface parts 18 and 20 is constant at the same height as the front surface part 14, and the rear half of the side surface parts 18 and 20 is also gradually raised toward the rear, the product is taken out from the side. Becomes easy. Furthermore, as will be understood from FIG. 2, the aesthetic appearance is also excellent.

以上、本発明の最良の実施形態について詳細に説明したが、本発明は上記実施形態に限定されないことは言うまでもない。例えば、切込み線５０，５２，５６，５８の高さ位置や幅は包装される商品等により適宜変更される。   Although the best embodiment of the present invention has been described in detail above, it goes without saying that the present invention is not limited to the above embodiment. For example, the height positions and widths of the cut lines 50, 52, 56, and 58 are appropriately changed depending on the product to be packaged.
