次にこの箱体形成片12の組み立て方法について、図1、図2に基づいて説明する。上述のように、図1は箱体形成片12を裏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、裏面側が凹になる折り方を逆折りと称する。   Next, a method for assembling the box forming piece 12 will be described with reference to FIGS. As described above, FIG. 1 is a view of the box-forming piece 12 from the back side. Hereinafter, the folding method in which the front side of the box-forming piece 12 is convex and the folding method in which the back side is concave will be described. This is called reverse folding.

まず、折罫線28を正折りし、正面補助板22の押圧吸収部72を除く表面側の広い範囲に糊82を塗布し、さらに折罫線24を正折りすることによって、正面補助板22の表面側を正面板14の裏面側に糊付する。箱体形成片12は、この状態で包装用箱10の工場から出荷される。   First, the crease line 28 is normally folded, the paste 82 is applied to a wide area on the surface side excluding the pressure absorbing portion 72 of the front auxiliary plate 22, and the crease line 24 is further folded forward, whereby the surface of the front auxiliary plate 22. The side is glued to the back side of the front plate 14. The box forming piece 12 is shipped from the factory of the packaging box 10 in this 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、図2(a)に示すように、四角形の筒状体を形成する。そして、底面側のフラップ50,68を各々折罫線52,70で90度に正折りし、内蓋片42の表面の折罫線44寄りの位置に糊84を塗布し、内蓋片42を折罫線44で90度に正折りする。さらに、外蓋片60を折罫線62で90度に正折りし、外蓋片60の裏面に内蓋片42の表面を糊付けする。この動作により、筒状体の底面側の端部が閉鎖される。そして、医薬品等の商品を、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 that stores and packs products, the crease lines 24, 26, 28, and 30 are each normally folded so as to be 90 degrees, and as shown in FIG. Form. Then, the flaps 50 and 68 on the bottom surface side are normally folded at 90 degrees along the crease lines 52 and 70, respectively, and paste 84 is applied to a position near the crease line 44 on the surface of the inner lid piece 42 , and the inner lid piece 42 is folded. Fold it forward at 90 degrees along the ruled line 44 . Further, the outer lid piece 60 is normally folded at 90 degrees along the crease line 62 , and the surface of the inner lid piece 42 is glued to the back surface of the outer lid piece 60 . By this operation, the bottom end portion of the cylindrical body is closed. And goods, such as a pharmaceutical, are inserted inward from the open edge part of the top | upper surface side of a cylindrical body.

その後、天面側のフラップ46,64を各々折罫線48,66で90度に正折りし、内蓋片32の表面の第一折罫線34寄りの位置に糊86を塗布し、内蓋片32を第一折罫線34で90度に正折りする。このとき、内蓋片32の内側にある補助フラップ76も同時に第二折罫線78で正折りされる。さらに、外蓋片54を折罫線56で90度に正折りし、外蓋片54の裏面に内蓋片32の表面を糊付けする。この動作により、筒状体の天面側の端部が閉鎖され、図2(b)に示す状態になって商品の包装作業が終了する。この状態で、天面側及び底面側は、図3(a),(b)に示す断面図ように封止された構造となる。   Thereafter, the flaps 46 and 64 on the top surface side are normally folded at 90 degrees along the crease lines 48 and 66, respectively, and glue 86 is applied to the surface of the inner lid piece 32 near the first crease line 34, and the inner lid piece. 32 is normally folded at 90 degrees along the first crease line 34. At this time, the auxiliary flap 76 inside the inner lid piece 32 is also normally folded along the second crease line 78. Further, the outer lid piece 54 is normally folded at 90 degrees along the crease line 56, and the surface of the inner lid piece 32 is glued to the back surface of the outer lid piece 54. By this operation, the end on the top surface side of the cylindrical body is closed, and the packaging operation of the product is completed as shown in FIG. In this state, the top surface side and the bottom surface side are sealed as shown in the cross-sectional views of FIGS.

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。開封するときは、まず、図4に示すように、正面板14の開封部40を指で押し込んで第二破断線38を破断させる。このとき、開封部40の内側には正面補助板22があるが、押圧吸収部72が内側に湾曲するので開封部40を押し込む障害にはならず、第二破断線40を容易に破断させることができる。   The operation of opening and resealing the packaging box 10 is performed as follows. When opening, first, as shown in FIG. 4, the opening part 40 of the front board 14 is pushed in with a finger, and the 2nd fracture | rupture line 38 is fractured | ruptured. At this time, there is the front auxiliary plate 22 inside the opening portion 40, but the pressure absorbing portion 72 is curved inward so that it does not become an obstacle to push the opening portion 40, and the second breaking line 40 can be easily broken. Can do.

次に、開封部40に指を掛けたまま、上方に引き上げるようにして第一破断線36を破断させ、外蓋片54及び内蓋片32を開く。このとき、開封部40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54が互いに糊付され、開封部40、内蓋片32及び外蓋片54が一体になっているので、本体から分離する部分がなくゴミ等は生じない。また、補助フラップ76は、第二折罫線78を介して正面補助板22と連続しているので、筒状体の端部を閉じる位置にそのまま残る。そして、図6に示すように、補助フラップ76、フラップ46,64を引き上げることによって筒状体の端部を開放し、中の商品を取り出す。   Next, with the finger placed on the opening portion 40, the first break line 36 is broken by pulling upward, and the outer lid piece 54 and the inner lid piece 32 are opened. At this time, the opening portion 40 is continuous with the inner lid piece 32 via the first crease line 34, and the inner lid piece 32 and the outer lid piece 54 are glued to each other. Since the lid piece 54 is integrated, there is no part separated from the main body, and no dust or the like is generated. Moreover, since the auxiliary | assistant flap 76 is following the front auxiliary | assistant board 22 via the 2nd crease line 78, it remains in the position which closes the edge part of a cylindrical body as it is. And as shown in FIG. 6, the auxiliary | assistant flap 76 and the flaps 46 and 64 are pulled up, the edge part of a cylindrical body is open | released, and the goods inside are taken out.

開封後、包装用箱10の中に商品を戻して再封するときは、フラップ46,64を閉じ、補助フラップ76を閉じ、図7に示すように、補助フラップ76の基端部の差込孔80内に開封部40を差し込み、係合させることによって筒状体の端部を閉鎖する。このとき、開封部40のU字舌片状の先端部分が差込孔80の円弧状の周縁部にガイドされ、開封部40をスムーズに差し込むことができ、開封部40により差込孔80は塞がれる。   When the product is returned to the packaging box 10 after being opened and resealed, the flaps 46 and 64 are closed, the auxiliary flap 76 is closed, and the proximal end portion of the auxiliary flap 76 is inserted as shown in FIG. The end portion of the cylindrical body is closed by inserting and engaging the opening portion 40 into the hole 80. At this time, the U-shaped tongue-shaped tip portion of the opening portion 40 is guided by the arc-shaped peripheral edge portion of the insertion hole 80, and the opening portion 40 can be smoothly inserted. It is blocked.

以上説明したように、この実施形態の包装用箱10は、簡単な構造で組み立て易く、外蓋片54を開封する操作が容易で、開封後も違和感なく確実に再封することができる。また、従来のシールエンドカートン(正面補助板22に代えて小さな糊付片が設けられた一般的な箱体)に用いられる既存の包装装置を利用することも可能である。   As described above, the packaging box 10 of this embodiment is easy to assemble with a simple structure, easy to open the outer lid piece 54, and can be reliably resealed even after opening without a sense of incongruity. It is also possible to use an existing packaging device used in a conventional sealed end carton (a general box provided with small paste pieces instead of the front auxiliary plate 22).

また、開封後の天面部分は、外蓋片54が内側の内蓋片32によって補強され、正面板14が正面補助板22によって補強され、再封する際に外力が加わりやすい開封部40及び差込孔80の部分についても破れにくい構造になっている。また、開封部40が除去された正面板14の窓部分は、正面補助板22によって塞がれ、商品が外部に露出しない。従って、再封状態での商品保護性にも優れている。   In addition, the top surface portion after opening has the outer cover piece 54 reinforced by the inner inner cover piece 32, the front plate 14 is reinforced by the front auxiliary plate 22, and the opening portion 40 and the external force that is easily applied with external force when resealed The structure of the insertion hole 80 is also difficult to break. Moreover, the window part of the front board 14 from which the opening part 40 was removed is blocked | closed by the front auxiliary board 22, and goods are not exposed outside. Therefore, it is excellent in product protection in a resealed state.

さらに、外蓋片54,60及び内蓋片42の基端部の位置に第三破断線58、破断線63及び44が設けられているので、包装用箱10を廃棄する際、容易に解体して平坦に折り畳むことができる。   Furthermore, since the third break line 58 and the break lines 63 and 44 are provided at the positions of the base end portions of the outer lid pieces 54 and 60 and the inner lid piece 42, when the packaging box 10 is discarded, it is easily disassembled. And can be folded flat.
