Description

この発明は、商品等を収容し、開封側の開口部が糊付けして封止されるシールエンドカートン型の包装用箱に関する。 The present invention relates to a sealed end carton type packaging box for accommodating products and the like and having an opening on the opening side glued and sealed.

従来から、商品を収容して搬送し店頭に陳列等するための包装用箱として、一枚の箱体形成片を立体的に組み立てたシートエンドカートン型の包装用箱が使用されている。この箱体形成片には、平行に連接された４つの側面と、一側面の両端部に形成された外蓋片と、組み立て状態でこの側面に対向する側面の両端部に形成された内蓋片と、その他の一対の側面の両端部に形成されたフラップが設けられ、連接方向の外側に位置する一側面の側縁部には小さい糊付片が設けられている。 Conventionally, a sheet-end carton type wrapping box in which one box body forming piece is three-dimensionally assembled has been used as a wrapping box for storing and transporting products and displaying them at a store. The box body forming piece includes four side surfaces connected in parallel, an outer lid piece formed on both ends of one side surface, and an inner lid formed on both ends of the side surface facing the side surface in the assembled state. Flaps formed on both ends of the piece and the other pair of side surfaces are provided, and small glue pieces are provided on the side edges of one side surface located outside in the connecting direction.

この箱体形成片を組み立てるときは、糊付片をその反対側の側面裏面に糊付けし、各側面が各々直角になるように起こして四角い筒状体を形成し、筒状体の一端部にある一対のフラップを側面に対して直角に折り曲げ、次に内蓋片を折り曲げ、その内蓋片の表面に糊を塗布し、その上面に外蓋片を折り重ねて糊付けして閉鎖する。そして、商品を収容後、筒状体の他方の端部も同様に閉鎖するものである。 When assembling this box body forming piece, glue the glued piece to the back surface of the opposite side surface, raise each side surface at a right angle to form a square tubular body, and attach it to one end of the tubular body. A pair of flaps is bent at a right angle to the side surface, then the inner lid piece is bent, glue is applied to the surface of the inner lid piece, and the outer lid piece is folded and glued on the upper surface to close the inner lid piece. Then, after accommodating the product, the other end of the tubular body is similarly closed.

しかし、シールエンドカートンは、一旦開封すると後に再封することができず、箱体内に商品が残っている場合の封止に問題があった。 However, once the seal end carton is opened, it cannot be resealed later, and there is a problem in sealing when the product remains in the box.

そこで、例えば、特許文献１に開示されているように、開封される正面板（正面部）に、外蓋片（第１フラップ）に連続する開封部（被押圧部）を形成し、その内側に内側カバー面部を配置した包装箱があった。この包装箱は、開封後、内側カバー面部の内側に開封部を差し込むことによって再封可能にしている。 Therefore, for example, as disclosed in Patent Document 1, an opening portion (pressed portion) continuous with the outer lid piece (first flap) is formed on the front plate (front portion) to be opened, and the inside thereof is formed. There was a packaging box in which the inner cover surface was arranged. After opening, this packaging box can be resealed by inserting the opening portion inside the inner cover surface portion.

次に、箱体形成片１２の組み立て方法の一例を説明する。図１は箱体形成片１２を表面側から見たものであり、以下、箱体形成片１２の表面側が凸になる折り方を正折り、裏面側が凸になる折り方を逆折りと称する。 Next, an example of how to assemble the box body forming piece 12 will be described. FIG. 1 shows the box body forming piece 12 viewed from the front surface side. Hereinafter, the folding method in which the front surface side of the box body forming piece 12 is convex is referred to as normal folding, and the folding method in which the back surface side is convex is referred to as reverse folding.

まず、糊付け片２２の表面に糊を塗布し、折罫線２８を正折りし、さらに折罫線２４を正折りして糊付け片２２の表面と第一の側面板１４の裏面を糊付する。箱体形成片１２は、この折り畳み状態で包装用箱１０の製造工場から出荷される。 First, glue is applied to the surface of the glued piece 22, the folded ruled line 28 is folded forward, and the folded ruled line 24 is folded forward to glue the front surface of the glued piece 22 and the back surface of the first side plate 14. The box body forming piece 12 is shipped from the manufacturing factory of the packaging box 10 in this folded state.

次に、商品を収容し包装する工場等において、折罫線２４，２６，２８，３０を各々９０度になるように正折りし、四角形の筒状体を形成する。そして、底面側のサイドフラップ６４，７２を各々折罫線６６，７４で９０度に正折りし、外蓋片５６の裏面または内蓋片４０の表面に糊を塗布し、内蓋片４０を折罫線４２で９０度に正折りし、外蓋片５６を折罫線５８で９０度に正折りし、外蓋片５６を内蓋片４０に重ねて糊付けする。この作業により、筒状体の底面側の端部が閉鎖される。この後、商品を筒状体の天面側の開放している端部から内側に挿入する。 Next, in a factory or the like for accommodating and packaging products, the folding ruled lines 24, 26, 28, and 30 are normally folded at 90 degrees to form a quadrangular cylindrical body. Then, the side flaps 64 and 72 on the bottom surface side are folded forward at 90 degrees along the fold ruled lines 66 and 74, respectively, glue is applied to the back surface of the outer lid piece 56 or the front surface of the inner lid piece 40, and the inner lid piece 40 is folded. The outer lid piece 56 is folded forward at 90 degrees along the ruled line 42, the outer lid piece 56 is folded forward at 90 degrees along the ruled line 58, and the outer lid piece 56 is overlapped with the inner lid piece 40 and glued. This operation closes the bottom end of the tubular body. After that, the product is inserted inward from the open end on the top surface side of the tubular body.

この後、天面側のサイドフラップ６０，６８を各々折罫線６２，７０で９０度に正折りし、外蓋片５２の裏面または内蓋片３２の表面の、糊付け状態で内蓋片３２の第二折罫線３６より先端側となる部分に糊を塗布する。そして、内蓋片３２を第一折罫線３４で９０度に正折りし、外蓋片５２を折罫線５４で９０度に正折りし、外蓋片５２を内蓋片３２の第二折罫線３６よりも先端側の部分に糊付けする。この工程により、筒状体の天面側の端部も閉鎖された組み立て状態となり、商品の包装作業が終了する。 After that, the side flaps 60 and 68 on the top surface side are folded forward at 90 degrees along the fold ruled lines 62 and 70, respectively, and the inner lid piece 32 is glued on the back surface of the outer lid piece 52 or the front surface of the inner lid piece 32. Glue is applied to the portion on the tip side of the second fold ruled line 36. Then, the inner lid piece 32 is normally folded 90 degrees along the first fold ruled line 34, the outer lid piece 52 is normally folded 90 degrees along the fold ruled line 54, and the outer lid piece 52 is normally folded 90 degrees along the second fold ruled line of the inner lid piece 32. Glue to the tip side of 36. By this step, the end portion of the tubular body on the top surface side is also in a closed assembled state, and the product packaging work is completed.

なお、商品を収容する順序は、上記以外に、先に上述のように天面側の外蓋片５２を内蓋片３２に糊付けして閉鎖し、底面側から商品を収容した後、底面側を上述のように閉鎖しても良い。 In addition to the above, the order of accommodating the products is as described above, the outer lid piece 52 on the top surface side is glued to the inner lid piece 32 to close the product, and the products are stored from the bottom surface side, and then the bottom surface side. May be closed as described above.

図２に示す組み立て状態で、内蓋片３２は、第二折罫線３６より先端側の部分が外蓋片５２に重なって糊付けされるが、第二折罫線３６と第一折罫線３４に挟まれた部分は、外蓋片５２に重ならずに露出する。また、図示していないが、サイドフラップ６０の端縁６０ａは、サイドフラップ６０の先端に近くなるほど第一折罫線３４から離れるように傾斜して配置され、サイドフラップ６８の端縁６８ａは、サイドフラップ６８の先端に近くなるほど第一折罫線３４から離れるように傾斜して配置される。 In the assembled state shown in FIG. 2, the inner lid piece 32 is glued so that the portion on the tip side of the second fold ruled line 36 overlaps the outer lid piece 52, but is sandwiched between the second fold ruled line 36 and the first fold ruled line 34. The exposed portion is exposed without overlapping the outer lid piece 52. Further, although not shown, the edge 60a of the side flap 60 is arranged so as to be inclined so as to be closer to the tip of the side flap 60 and away from the first fold ruled line 34, and the edge 68a of the side flap 68 is arranged on the side. The closer to the tip of the flap 68, the more inclined the first fold ruled line 34 is.

包装用箱１０を開封及び再封する操作は、以下のように行う。まず、開封するときは、正面板１６の開封部４６を指で押し込んで開封用破断線４４を破断させ、開封部４６に指を掛けたまま上方に引き上げて内蓋片３２及び外蓋片５２を開く。このとき、開封部４６は第一折罫線３４を介して内蓋片３２と連続し、且つ、内蓋片３２及び外蓋片５２が互いに糊付されているので、本体から分離する部分がなく、ゴミ等は生じない。 The operation of opening and resealing the packaging box 10 is performed as follows. First, when opening, the opening portion 46 of the front plate 16 is pushed in with a finger to break the opening breaking line 44, and the inner lid piece 32 and the outer lid piece 52 are pulled upward with the opening portion 46 covered with a finger. open. At this time, since the opening portion 46 is continuous with the inner lid piece 32 via the first fold ruled line 34 and the inner lid piece 32 and the outer lid piece 52 are glued to each other, there is no portion to be separated from the main body. , No dust is generated.

この後、サイドフラップ６０，６８を引き上げると、図３に示すように筒状体の端部が開放し、中の商品を取り出すことができる。 After that, when the side flaps 60 and 68 are pulled up, the end portion of the tubular body is opened as shown in FIG. 3, and the product inside can be taken out.

開封後、包装用箱１０を再封するときは、まず図４（ａ）に示すように、筒状体の開口端を塞ぐようにサイドフラップ６０，６８を倒す。その後、サイドフラップ６０，６８に重ねるように内蓋片３２及び外蓋片５２を倒し、開封部４６を内蓋片３２に対してほぼ９０度に正折りする。そして、開封部４６及び第一折罫線３４を背面板２０の方向に押し込む。 When resealing the packaging box 10 after opening, first, as shown in FIG. 4A, the side flaps 60 and 68 are tilted so as to close the open end of the tubular body. After that, the inner lid piece 32 and the outer lid piece 52 are tilted so as to overlap the side flaps 60 and 68, and the opening portion 46 is folded forward at approximately 90 degrees with respect to the inner lid piece 32. Then, the opening portion 46 and the first folding ruled line 34 are pushed in the direction of the back plate 20.

すると、図４（ｂ）に示すように、第二折罫線３６が折れて内蓋片３２が外向きに屈折し、一対の切り込み３８が背面板２０の方向にスムーズに移動する。そして、一対の切り込み３８の中に、サイドフラップ６０，６８の傾斜している端縁６０ａ，６８ａが円滑に入り込み、互いに係合して再封される。 Then, as shown in FIG. 4B, the second folding ruled line 36 is broken, the inner lid piece 32 is refracted outward, and the pair of notches 38 smoothly move in the direction of the back plate 20. Then, the inclined end edges 60a, 68a of the side flaps 60, 68 smoothly enter the pair of notches 38, engage with each other, and are resealed.

包装用箱１０を廃棄する時は、まず、正面板１６の押圧部５０を指で押し込んで分解用破断線４８を破断させ、押圧部５０に指を掛けたまま上方に引き上げて内蓋片４０及び外蓋片５６を開き、サイドフラップ６４，７２を引き上げて筒状体の底面側を開放する。さらに、再封されている天面側の端部も開放し、包装用箱１０を折り畳んで廃棄する。 When disposing of the packaging box 10, first, the pressing portion 50 of the front plate 16 is pushed in with a finger to break the disassembly breaking line 48, and the inner lid piece 40 is pulled upward while the finger is placed on the pressing portion 50.
