Description

本考案は、開封した蓋部を簡易的に再封することができる包装箱に関する。   The present invention relates to a packaging box that can easily re-seal an opened lid.

従来、例えば特許文献1に開示されているように、略直方体の箱体であって、前板の上縁部に、蓋部と連続する開封片が、開封切断線により切り込み可能に設けられ、開封片を押し込んで、蓋部を引き上げることによって開封することができる易開封密封カートンがあった。前記開封片の形状は半円形よりも大きい円弧状であり、開封すると、開封片が抜けた前板の上縁部に、内向き突起部が一対に形成される。したがって、開封した蓋部を閉じ、開封片を前板の穴(開封片が抜けた穴)に差し込み、開封片の幅広の部分を一対の内向き突起部に係合させることにより、蓋部を再封することができる。また、開封切断線を、同間隔の二重の半切れ線にする技術も記載されている。   Conventionally, for example, as disclosed in Patent Document 1, it is a substantially rectangular parallelepiped box, and an opening piece continuous with the lid portion is provided on the upper edge portion of the front plate so as to be cut by an opening cutting line, There was an easy-open sealing carton that could be opened by pushing the opening piece and lifting the lid. The opening piece has an arc shape larger than a semicircle, and when opened, a pair of inward projections are formed on the upper edge of the front plate from which the opening piece has been removed. Therefore, the lid is closed by closing the opened lid, inserting the opened piece into the hole in the front plate (the hole from which the opened piece has been removed), and engaging the wide portion of the opened piece with the pair of inward projections. Can be resealed. In addition, a technique is described in which the unsealing cutting line is a double half-cut line with the same interval.

特開2004−75080号公報JP 2004-75080 A

しかし、特許文献1の易開封密封カートンは、開封部の形状と前板の穴の形状とが同じなので、開封部と一対の内向き突起との係合が非常に弱く、再封状態が保持されにくいものである。この開封部は、箱体が正確な直方体に近づくとほとんど係合しなくなり、反対に、箱体の変形や歪みが大きいと、開封部の幅広の部分が内向き突起に係合できるようになるため、係合が強くなる。したがって、例えば、前板を外向きに湾曲させる等して箱体を意図的に変形させれば、一定の係合強度を得ることができる。しかし、箱体の変形を大きくすると見栄えが悪くなるので、あまり好ましい方法とは言えない。また、開封切断線を二重の半切れ線にすることで、箱体の変形が小さくても一定の係合強度が得られるが、易開封密封カートンを製作する工場で、基材に半切れ線を設けるための加工工程が増えてしまい、コストアップの原因となる。   However, since the shape of the opening portion and the shape of the hole in the front plate are the same in the easy-open sealing carton of Patent Document 1, the engagement between the opening portion and the pair of inward projections is very weak, and the resealed state is maintained. It is hard to be done. When the box is close to an accurate rectangular parallelepiped, the unsealed portion is almost disengaged. Conversely, when the box is largely deformed or distorted, the wide portion of the unsealed portion can be engaged with the inward projection. Therefore, the engagement becomes strong. Therefore, for example, if the box body is intentionally deformed by bending the front plate outward, a certain engagement strength can be obtained. However, when the deformation of the box is increased, the appearance is deteriorated, so that it is not a preferable method. In addition, by making the opening cutting line into a double half-cut line, a constant engagement strength can be obtained even if the deformation of the box is small. The number of processing steps for providing a line increases, which causes an increase in cost.

本考案は、上記背景技術に鑑みて成されたものであり、製作が容易で、開封した蓋部を一定の強度で簡易的に再封できる包装箱を提供することを目的とする。   The present invention has been made in view of the above-described background art, and an object thereof is to provide a packaging box that is easy to manufacture and that can easily re-seal an opened lid with a certain strength.

A side flap 48 extends from the other end of the side plate 16 and is separated from the side plate 16 by a crease line 50.

開封用側面板18の、側面板16の折罫線46に連続する端辺52の内側には、開封時に指で押圧可能な大きさの押圧部54が設けられている。押圧部54は、端辺52の中央部とU字状の破断線56に囲まれて周囲と区切られている。また、開封用側面板18の下端部である開封用端辺58には、外側底蓋片40より僅かに小さい内側底蓋片60が延設されている。   A pressing portion 54 having a size that can be pressed with a finger at the time of opening is provided inside the side edge 52 of the opening side plate 18 that is continuous with the crease line 46 of the side plate 16. The pressing portion 54 is surrounded by a central portion of the end side 52 and a U-shaped break line 56 and is separated from the surroundings. In addition, an inner bottom cover piece 60 that is slightly smaller than the outer bottom cover piece 40 extends from the opening end side 58 that is the lower end portion of the opening side plate 18.

開封用側面板18の下端部には、開封用端辺58の内側に、指で押圧可能な大きさの開封部64が設けられている。開封部64は、開封用端辺58の中央部と略U字状の開封用破断線62とで囲まれており、開封用端辺58側の端部が他の部分より幅狭に形成され、これにより、開封用側面板18の開封用端辺58の位置に、開封用破断線62で区切られた内向き突起部65a,65bが一対に設けられている。   At the lower end portion of the unsealing side plate 18, an unsealing portion 64 sized to be pressed with a finger is provided inside the unsealing end side 58. The opening portion 64 is surrounded by the center portion of the opening end side 58 and the substantially U-shaped opening breaking line 62, and the end portion on the opening end side 58 side is formed narrower than the other portions. Thus, a pair of inwardly projecting portions 65a and 65b separated by the opening breaking line 62 are provided at the position of the opening edge 58 of the opening side plate 18.

また、開封用破断線62は、一対の内向き突起部65a,65bの近傍に、一対のL字状切目62a,62bを有している。L字状切目62aは、切り残し部を有して開封部64の輪郭と略平行な平行部分と、平行部分の端部から外向きの角度に延びる屈曲部とで成り、平行部分と屈曲部分とが互いに鈍角に交わるよう設けられている。他方のL字状切目64bも同様である。開封用破断線62を構成するその他の切目は、いわゆるミシン目であり、開封部64の輪郭と略平行な部分だけを有している。   Further, the breaking line 62 for opening has a pair of L-shaped cuts 62a and 62b in the vicinity of the pair of inwardly protruding portions 65a and 65b. The L-shaped cut line 62a is formed by a parallel part that has an uncut part and is substantially parallel to the outline of the opening part 64, and a bent part that extends outward from the end of the parallel part, and the parallel part and the bent part. Are provided to cross each other at an obtuse angle. The same applies to the other L-shaped cut 64b. The other cuts constituting the breaking line 62 for opening are so-called perforations, and have only a portion substantially parallel to the outline of the opening 64.

開封用側面板18の開封部64と内側底蓋片60とを区切る位置には折罫線58aが設けられ、開封用側面板18の他の部分と内側底蓋片60とを区切る位置にはミシン目状の破断線58bが設けられている。   A folding line 58a is provided at a position where the opening portion 64 and the inner bottom cover piece 60 of the opening side plate 18 are separated, and a sewing machine is provided at a position where the other portion of the opening side plate 18 and the inner bottom cover piece 60 are separated. An eye-shaped break line 58b is provided.

側面板20の、開封用側面板18の端辺52に連続する端部には、サイドフラップ66が延設され、折罫線68で側面板20と区切られている。側面板20の他端部には、サイドフラップ70が延設され、折罫線72で側面板18と区切られている。   A side flap 66 is extended at the end of the side plate 20 that is continuous with the end side 52 of the unsealing side plate 18, and is separated from the side plate 20 by a crease line 68. A side flap 70 extends from the other end of the side plate 20 and is separated from the side plate 18 by a crease line 72.

次に、再封可能な包装箱10の組み立て方法の一例を説明する。ここで、箱体形成片12の表面が凸になる折り方を正折り、そして裏面が凸になる折り方を逆折りと称する。   Next, an example of a method for assembling the resealable packaging box 10 will be described. Here, the folding method in which the front surface of the box-forming piece 12 is convex is referred to as normal folding, and the folding method in which the back surface is convex is referred to as reverse folding.

まず、折罫線24を正折して、糊付け片22を側面板14に重ね、糊付け片22の表面に糊を塗布する。そして、折罫線28を正折りして、側面板20の裏面の端部を糊付け片22の表面に糊付けする。箱体形成片12は、この折り畳まれた状態で出荷される。   First, the crease line 24 is folded forward, the glue piece 22 is overlaid on the side plate 14, and glue is applied to the surface of the glue piece 22. Then, the crease line 28 is folded forward and the end of the back surface of the side plate 20 is glued to the surface of the glue piece 22. The box-forming piece 12 is shipped in this folded state.

次に商品を収容して包装する工場等において、折罫線24,26,28,30を各々90°に正折りし、四角形の筒体を形成する。その後、筒体の一端部を塞ぐ底蓋を設けるため、図3(a)、(b)、(c)に順に示すように、折罫線50,52でサイドフラップ48,70を各々90°に正折りし、開封用端辺58(折罫線58a、開封用破断線58b)で内側底蓋片60を90°に正折りする。その後、外側底蓋片40のほぼ中央部に糊76を塗布し、折罫線42で外側底蓋片40を90°に正折りし、外側底蓋片40の裏面を内側底蓋片60の表面に糊付し、外側底蓋片40と内側底蓋片60が一体になった底蓋部74が形成される。これで筒体に一端部が閉鎖されたので、開放している他端部から箱体の中に商品を入れる。   Next, in a factory or the like where products are stored and packaged, the crease lines 24, 26, 28 and 30 are each normally folded at 90 ° to form a rectangular cylinder. Thereafter, in order to provide a bottom lid for closing one end of the cylindrical body, the side flaps 48 and 70 are respectively set to 90 ° at the crease lines 50 and 52 as shown in FIGS. 3 (a), (b) and (c). The inner bottom cover piece 60 is normally folded at 90 ° at the opening end side 58 (the crease line 58a, the opening break line 58b). Thereafter, paste 76 is applied to the substantially central portion of the outer bottom cover piece 40, the outer bottom cover piece 40 is normally folded at 90 ° along the crease line 42, and the back surface of the outer bottom cover piece 40 is placed on the surface of the inner bottom cover piece 60. The bottom cover part 74 which the outer bottom cover piece 40 and the inner bottom cover piece 60 were united is formed. Now that one end of the cylinder has been closed, the product is put into the box from the other open end.

次に、図4(a)、(b)、(c)に順に示すように、折罫線46,68でサイドフラップ44,66を各々90°に正折りし、差し込み片36の表面中央部に糊78を塗布する。そして、折罫線34で天蓋片32を90°に正折りし、折罫線38で差し込み片36を90°に正折りし、差し込み片36を開封用側面板18の内側に差し込み、糊78により押圧部54の裏面に糊付けすし、天蓋片32で成る天蓋部80により、箱体の他端部も閉鎖される。これで商品の包装作業が終了して図1(a)、(b)に示す組み立て状態となり、この状態で商品が出荷され、商店等で販売される。なお、商品を入れる順序は、天蓋片32側を先に組み立てた後、商品を挿入して、外側底蓋片40を閉じても良い。   Next, as shown in order in FIGS. 4A, 4B, and 4C, the side flaps 44 and 66 are each folded forward at 90 ° along the crease lines 46 and 68, respectively, at the center of the surface of the insertion piece 36. Glue 78 is applied. Then, the canopy piece 32 is normally folded at 90 ° by the crease line 34, the insertion piece 36 is normally folded at 90 ° by the crease line 38, and the insertion piece 36 is inserted into the inside of the side plate 18 for opening and pressed by the glue 78. The other end portion of the box is also closed by the canopy portion 80 formed of the canopy piece 32 and pasted on the back surface of the portion 54. Thus, the product packaging operation is completed, and the assembled state shown in FIGS. 1A and 1B is obtained. In this state, the product is shipped and sold in a store or the like. In addition, after putting the canopy piece 32 side first, the order which puts goods may insert goods, and may close the outer bottom cover piece 40. FIG.

再封可能な包装箱10は、図1に示すように、天蓋部80側と底蓋部74側のそれぞれに、開封及び再封を行う構造が設けられている。商品を購入した使用者は、商品の出し入れについては、天蓋部80側で行う。底蓋部74側は、例えば、箱体を折り畳んで廃棄するために開封したが、事情が変わってもうしばらく使用しなければならなくなったとき等に、底蓋部74を簡易的に再封するために使用する。本考案の要部は、底蓋部74側の構造である。   As shown in FIG. 1, the resealable packaging box 10 is provided with a structure for opening and resealing each on the canopy portion 80 side and the bottom lid portion 74 side. The user who purchased the product performs the putting in and out of the product on the canopy unit 80 side. For example, the bottom lid portion 74 is opened for folding and discarding the box, but the bottom lid portion 74 is simply resealed when the situation changes and it must be used for a while. Use for. The main part of the present invention is the structure on the bottom lid 74 side.

使用者が天蓋部80側を開封するときは、開封用側面板18の押圧部54を指で押して破断線56を破断させ、押圧部54を開封用側面板18から分離させる。そして、差し込み片36及び天蓋片32を引き上げると、天蓋部80で塞がれていた箱体の端部が開放し、中の商品を取り出すことができる。押圧部54は、開封用側面板18から分離するが、差し込み片36に糊付けされているのでゴミにはならない。   When the user opens the canopy 80 side, the pressing portion 54 of the opening side plate 18 is pressed with a finger to break the breaking line 56, and the pressing portion 54 is separated from the opening side plate 18. And if the insertion piece 36 and the canopy piece 32 are pulled up, the edge part of the box closed by the canopy part 80 will open | release, and the goods inside can be taken out. The pressing portion 54 is separated from the side plate 18 for opening, but since it is glued to the insertion piece 36, it does not become dust.
