本発明は、例えば葱、キャベツ、白菜などの野菜類を収納するのに好適な青果物の包装箱に関し、特にステープルを使用することなく、フラップの差し込みにより上蓋および底板がともに封緘され、かつその差し込みフラップによる商品の傷付きを防止する段ボール包装箱に関する。   The present invention relates to a fruit and vegetable packaging box suitable for storing vegetables such as rice cakes, cabbage, and Chinese cabbage, and in particular, without using staples, the upper lid and the bottom plate are sealed together by inserting a flap, and the insertion is performed. The present invention relates to a cardboard packaging box that prevents a product from being damaged by a flap.

青果物を収納する段ボール包装箱として、特許文献１に示すものが知られている。   As a corrugated cardboard packaging box for storing fruits and vegetables, the one shown in Patent Document 1 is known.

このような従来の段ボール包装箱は、例えば図７〜図９に示したように、１組の短辺側の対向側板１，１と、他の組の長辺側の対向側板２，２と、前記短辺側の対向側板１，１の下端に連設された底板形成用フラップ３，３と、前記長辺側の対向側板２，２の下端に連設された底板形成用フラップ４，４と、前記短辺側の対向側板１，１の上端に連設された上蓋形成用フラップ５，５と、前記長辺側の対向側板２，２の上端に連設された上蓋形成用フラップ６，６とから構成されている。   Such a conventional corrugated cardboard packaging box includes, for example, as shown in FIGS. 7 to 9, one set of opposing side plates 1, 1 on the short side and another side opposing side plates 2, 2 on the other side. , Bottom plate forming flaps 3, 3 connected to the lower ends of the opposite side plates 1, 1 on the short side, and bottom plate forming flaps 4 connected to the lower ends of the opposite side plates 2, 2 on the long side 4, upper lid forming flaps 5, 5 provided continuously with the upper ends of the opposite side plates 1, 1 on the short side, and upper cover forming flaps provided continuously with the upper ends of the opposed side plates 2, 2 on the long side 6 and 6.

さらに前記長辺側の対向側板２，２の下端に連設された底板形成用フラップ４，４は短辺の長さ方向の中間部で端面同士が近接し、前記短辺側の対向側板１，１の下端に連設された底板形成用フラップ３，３は底板形成用フラップ４，４上に載るように底板形成用フラップ４，４で形成される底板の端部に位置し、底板形成用フラップ３，３と底板形成用フラップ４，４をステープル７によって止めて底板が形成されている。また、上蓋については、前記長辺側の対向側板２，２の上端に連設された上蓋形成用フラップ６，６は短辺の長さ方向の中間部で端面同士が近接し、前記短辺側の対向側板１，１の上端に連設された上蓋形成用フラップ５，５は上蓋形成用フラップ６，６の内面に重なるように上蓋形成用フラップ６，６で形成される上蓋の端部に位置し、上蓋形成用フラップ５，５と上蓋形成用フラップ６，６をステープル８によって止めて上蓋が形成されている。なお、前記底板は包装箱の下端全体を閉じるように形成されているが、上蓋は中央部に矩形（図面では長方形）の通気用の開口部９が形成されるように上蓋形成用フラップ５および６の先端に凹状の切り欠き部５ａおよび６ａが形成されている。   Further, the bottom plate forming flaps 4 and 4 connected to the lower ends of the long side opposing side plates 2 and 2 are close to each other in the middle portion in the length direction of the short side, and the opposing side plate 1 on the short side side. The bottom plate forming flaps 3 and 3 connected to the lower end of the bottom plate 1 are positioned at the end of the bottom plate formed by the bottom plate forming flaps 4 and 4 so as to be placed on the bottom plate forming flaps 4 and 4. The bottom plates are formed by fastening the flaps 3 and 3 and the bottom plate forming flaps 4 and 4 with staples 7. As for the upper lid, the upper lid forming flaps 6 and 6 connected to the upper ends of the opposite side plates 2 and 2 on the long side are intermediate portions in the length direction of the short sides and end surfaces thereof are close to each other. Ends of the upper lid formed by the upper lid forming flaps 6 and 6 so that the upper lid forming flaps 5 and 5 connected to the upper ends of the opposite opposing side plates 1 and 1 overlap the inner surfaces of the upper lid forming flaps 6 and 6. The upper lid forming flaps 5 and 5 and the upper lid forming flaps 6 and 6 are fastened by staples 8 to form the upper lid. The bottom plate is formed so as to close the entire lower end of the packaging box. However, the upper lid is formed with a rectangular (in the drawing, rectangular) ventilation opening 9 at the center, and the upper lid forming flap 5 and Concave notches 5 a and 6 a are formed at the tip of 6.

上記構成において、底板形成用フラップ３，３と底板形成用フラップ４，４および上蓋形成用フラップ５，５と上蓋形成用フラップ６，６はともにステープル７および８によって止められている。しかし、ステープルはステープル打ち込み機械により箱に打ち込むものであるから、そのステープル打ち込み作業は農家にとっては面倒である。また開封・解体作業時にステープルにより怪我をしたり、商品である野菜の中にはステープルが混入しやすいため、農家や流通業者に嫌われている。また、使用済み箱のリサイクルの際には、ステープルと段ボールの分別作業に手間がかかり、処理コストが嵩むという欠点があることから、ノンステープル形式の包装箱が農家や流通業者から要望されている。   In the above configuration, the bottom plate forming flaps 3 and 3, the bottom plate forming flaps 4 and 4, the upper lid forming flaps 5 and 5, and the upper lid forming flaps 6 and 6 are both stopped by staples 7 and 8. However, since staples are driven into a box by a staple driving machine, the staple driving operation is troublesome for farmers. In addition, they are injured by staples at the time of opening and dismantling work, and staples are easily mixed into vegetables, which are products, so they are hated by farmers and distributors. In addition, when recycling used boxes, there is a disadvantage that it takes time to separate staples and corrugated cardboard, resulting in increased processing costs. Therefore, non-staple packaging boxes are demanded by farmers and distributors. .

また、特許文献２〜４に開示されているような包装箱にあっては、一方のフラップに形成された差し込み片を相対する他方のフラップに形成された差込溝に嵌挿させるとき、差し込み片の先端で、包装箱の内部に収納された野菜などに傷を付けるという問題があった。

前記天板形成用フラップ１５ａ，１５ｂのうち、対向側板１１，１１に近接するフラップ１５ａは、前記連設線と直交する方向に伸びる一組のフラップ差し込み用スリット３０を形成する。各一組のスリット３０は、背中合わせで向き合うコ字形と逆コ字形の切れ線３１ａと前記切れ線３１ａに囲まれてフラップの側縁に向かう折曲げ舌片３１ｂとから形成されている。   Of the top plate forming flaps 15a and 15b, the flap 15a adjacent to the opposing side plates 11 and 11 forms a set of flap insertion slits 30 extending in a direction perpendicular to the continuous line. Each set of slits 30 is formed of a U-shaped and reverse U-shaped cut line 31a facing each other back to back, and a bent tongue 31b surrounded by the cut line 31a toward the side edge of the flap.

なお、長辺側の対向側板１２，１２の上端に連設する天板形成用フラップ１６は、対向側板１１，１１の幅員をＷとしたとき、１／２Ｗよりも短い寸法のショートフラップに形成されている。このような短い寸法に設定することで、組立て時に箱天面に後述のように開口部が形成されるのである。
また、天板形成用フラップ１６の先端側角部には平行折り目線３３により区画した外えん片３４を設け、その延長上に一対の差し込みフラップ３５，３５を設ける。因みに差し込みフラップ３５,３５は、前記各一組のスリット３０に挿入できるように形成されている。 The top plate forming flaps 16 connected to the upper ends of the opposite side plates 12 and 12 on the long side are formed as short flaps having dimensions shorter than 1/2 W, where W is the width of the opposite side plates 11 and 11. Has been. By setting such a short dimension, an opening is formed on the top of the box at the time of assembly as will be described later.
Further, an outer edge piece 34 partitioned by a parallel crease line 33 is provided at the tip side corner of the top plate forming flap 16, and a pair of insertion flaps 35, 35 are provided on the extension. Incidentally, the insertion flaps 35, 35 are formed so that they can be inserted into the respective sets of slits 30.

以上のように形成された箱のブランクを組み立てるときは、図１に符号３６で示した繋ぎ代を介し、先ず四枚の対向側板１１，１１、１２，１２を連係して角筒状の胴壁を形成する。   When assembling the blank of the box formed as described above, the four opposing side plates 11, 11, 12, and 12 are first linked to each other through the joining margin indicated by reference numeral 36 in FIG. Form a wall.

底を組み立てるときは、先ず前記対向側板１１，１１の下端に連設した底板形成用フラップ１３ａ，１３ｂを平行折り目線１７より二つ折りし、フラップ先端部の係止突起１８をロック孔１９に押し込む。この状態で、底板形成用フラップ１３ａ，１３ｂは後述するように、差し込みフラップ２４，２４を収納できる鞘部となる。   When assembling the bottom, first, the bottom plate forming flaps 13a and 13b connected to the lower ends of the opposed side plates 11 and 11 are folded in two from the parallel crease line 17, and the locking protrusion 18 at the front end of the flap is pushed into the lock hole 19. . In this state, the bottom plate forming flaps 13a and 13b become sheath portions that can accommodate the insertion flaps 24 and 24, as will be described later.

次に、長辺側の対向側板１２，１２の下端に設けた底板形成用フラップ１４ａ，１４ｂを折り目線２２よりくの字形に折り曲げつつ、底板形成用フラップ１４ｂの先端側角部に設ける切込み２３、２３を介して差し込みフラップ２４，２４を底板形成用フラップ１３ａに形成した各スリット２０に挿入する。スリット２０はコ字形または逆コ字形の切れ線２１ａと折曲げ舌片２１ｂとからなり、前記折曲げ舌片２１ｂは前記差し込みフラップ２４を前記差し込み用スリット２０に差し込んだ際、差し込みフラップ２４に当接して前記差し込み用スリットから抜け止めするように作用するのである。
なお長辺側の対向側板１２，１２の下端に設けた底板形成用フラップ１４ａ，１４ｂ間には対向側板１２，１２との連設線と平行な折れ目線２２が形成され、この折れ目線２２によってスリット２０に対する底板形成用フラップ１4ｂの角部の差し込み作業を行なうとき、底板形成用フラップ１４ａ、14ｂを折れ目線２２の部分で折り曲げながら行なえるようになっている。 Next, the bottom plate forming flaps 14a and 14b provided at the lower ends of the opposing side plates 12 and 12 on the long side are folded into a square shape from the crease line 22, and cuts 23 provided at the front end side corners of the bottom plate forming flap 14b. The insertion flaps 24, 24 are inserted into the slits 20 formed in the bottom plate forming flap 13a. The slit 20 comprises a U-shaped or reverse U-shaped cut line 21a and a bent tongue piece 21b. The bent tongue piece 21b contacts the insertion flap 24 when the insertion flap 24 is inserted into the insertion slit 20. It acts so that it comes into contact with and prevents the insertion slit from coming off.
A fold line 22 is formed between the bottom plate forming flaps 14 a, 14 b provided at the lower ends of the opposite side plates 12, 12 on the long side, and is parallel to the continuous line with the opposite side plates 12, 12. When inserting the corners of the bottom plate forming flap 14b into the slit 20, the bottom plate forming flaps 14a and 14b can be bent while being folded at the fold line 22.

天面を封緘する場合は、底を組み立てる場合と同様に、先ず前記対向側板１１，１１の上端に連設した天板形成用フラップ１５ａ，１５ｂを平行折り目線２５より二つ折りし、フラップ先端部の係止突起２６をロック孔２７に押し込む。この状態で、天板形成用フラップ１５ａ，１５ｂは後述するように、差し込みフラップ３５，３５を収納することができる鞘部となる。   When sealing the top surface, as in the case of assembling the bottom, first, the top plate forming flaps 15a and 15b connected to the upper ends of the opposing side plates 11 and 11 are folded in two from the parallel crease line 25, and the front end of the flap Is pushed into the lock hole 27. In this state, the top plate forming flaps 15a and 15b become sheath portions that can accommodate the insertion flaps 35 and 35, as will be described later.

次に、長辺側の対向側板１２，１２の上端に設けた天板形成用フラップ１６，１６を外えん片３４に設けた折り目線３３よりくの字形に折り曲げつつ、天板形成用フラップ１６の先端側角部に設ける差し込みフラップ３５、３５を天板形成用フラップ１５ａに形成した各スリット３０に挿入する。スリット３０はコ字形または逆コ字形の切れ線３１ａと折曲げ舌片３１ｂとからなり、前記折曲げ舌片３１ｂは前記差し込みフラップ３５を前記差し込み用スリット３０に差し込んだ際、差し込みフラップ３５に当接して前記差し込み用スリットから抜け止めするように作用するのである。   Next, the top plate forming flaps 16 and 16 are bent into a U-shape from the crease line 33 provided on the outer ledge piece 34 while the top plate forming flaps 16 and 16 provided on the upper ends of the opposing side plates 12 and 12 on the long side are folded. The insertion flaps 35, 35 provided at the tip side corners are inserted into the respective slits 30 formed in the top plate forming flap 15a. The slit 30 comprises a U-shaped or reverse U-shaped cut line 31a and a bent tongue piece 31b. The bent tongue piece 31b contacts the insertion flap 35 when the insertion flap 35 is inserted into the insertion slit 30. It acts so that it comes into contact with and prevents the insertion slit from coming off.
