Description

この発明は、商品等を収容し両端開口部を糊付けして封止す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 that accommodates merchandise and the like and glues and seals openings at both ends.

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、一枚のブランクシートから一体的に打ち抜かれた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 packaging in which a box-shaped piece integrally punched from one blank sheet is three-dimensionally assembled as a packaging box for storing goods, transporting them, and displaying them at a storefront. A box is used. The box-forming piece includes four side surfaces connected in parallel, outer lid pieces formed at both end portions of one side surface, and inner lids formed at both end portions of the side surfaces facing the side surfaces in an assembled state. Flaps formed at both ends of the piece and the other pair of side surfaces are provided, and small glued pieces are provided at the side edge portions on one side located outside 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-forming piece, glue the glued piece to the back of the opposite side surface, raise each side to be at right angles to form a square cylindrical body, and attach it to one end of the cylindrical body. A pair of flaps are bent at right angles to the side surfaces, then the inner lid piece is folded, glue is applied to the surface of the inner lid piece, the outer lid piece is folded on the upper surface and glued and closed. And after accommodating goods, the other edge part of a cylindrical body is closed similarly.

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 a product remains in the box.

そこで、例えば、特許文献１，２に開示されているように、開封される一側面に差し込み片を形成し、その内側に内側壁板を設け、開封後にも内側壁板に形成されたスリットに外側の差し込み片を挿入可能に形成された包装用箱が多数提案されている。   Therefore, for example, as disclosed in Patent Documents 1 and 2, an insertion piece is formed on one side to be opened, an inner wall plate is provided on the inner side, and the slit formed on the inner wall plate after opening is also provided. Many packaging boxes formed so that an outer insertion piece can be inserted have been proposed.

また、特許文献３に開示されているように、再封可能な包装用箱であって、蓋体先端部の差し込み部分への差し込みが可能であるとともに、蓋体先端部を側面板側に掛け止めることができるようにし、蓋体の再閉鎖に際して、差し込みと掛け止めを使用者側で自由に選択できるようにした包装用箱も提案されている。   Further, as disclosed in Patent Document 3, the packaging box is a re-sealable packaging that can be inserted into the insertion portion of the lid body tip portion, and the lid body tip portion is hung on the side plate side. There has also been proposed a packaging box that can be stopped and can be freely selected by the user for insertion and latching when the lid is closed again.

しかし、特許文献１，２に開示された包装容器は、開封後の再封に際して、差し込み片を側面の中央部に形成された差し込み用のスリットに差し込むので、側面の中に形成されたスリットに差し込み片を挿入する操作が難しく、容易に差し込みできないという問題があった。   However, the packaging containers disclosed in Patent Documents 1 and 2 insert the insertion piece into the insertion slit formed in the central portion of the side surface when resealing after opening, so that the slit formed in the side surface There was a problem that the operation of inserting the insertion piece was difficult and could not be easily inserted.

また、特許文献３に開示された包装用箱は、再封に際して、差し込みと引き掛けを選択できるが、この場合も、差し込み動作は上記と同様に面倒であり、引き掛け片の係止も通常の再封動作と異なり面倒なものであった。   In addition, the packaging box disclosed in Patent Document 3 can be selected to be inserted and hooked at the time of resealing. In this case as well, the inserting operation is troublesome as described above, and the hooking piece is usually locked. Unlike the re-sealing operation, it was troublesome.

この発明は、上記背景技術に鑑みて成されたものであり、簡単な構造で容易に開封及び再封を行うことができるシールエンドカートン型の包装用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 background art, and an object thereof is to provide a sealed end carton type packaging box that can be easily opened and resealed with a simple structure.

次に、この箱体形成片１２の組み立て方法について、図１〜図４を基にして説明する。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. FIG. 1 is a view of the box-forming piece 12 as viewed from the back side. Hereinafter, a folding method in which the front side of the box-forming piece 12 is convex is referred to as normal folding, and a folding method in which the back side is concave is referred to as reverse folding.

まず、正面板１４の裏面の両側折罫線と平行に、対面する裏面板２２の押圧吸収部７４の両側に位置する箇所から縦方向に適宜の幅で、図示しない糊を塗布し、折罫線２８を正折りし、折罫線２４を正折りして、裏面板２２の表面と正面板１４の裏面を糊付する。箱体形成片１２は、この状態で包装用箱１０の製造工場から出荷される。   First, a paste (not shown) is applied in an appropriate width in the vertical direction from locations located on both sides of the pressure absorbing portion 74 of the back plate 22 facing each other in parallel with both side crease lines on the back surface of the front plate 14. Is folded forward, the crease line 24 is folded forward, and the front surface of the back plate 22 and the back surface of the front plate 14 are glued. The box forming piece 12 is shipped from the manufacturing 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、外蓋片４２の裏面または内蓋片６０表面に糊を塗布し、内蓋片６０を折罫線６２で９０度に正折りし、外蓋片４２を折罫線４４で９０度に正折りし、外蓋片４２の裏面と内蓋片６０の表面を糊付けする。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、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 where products are stored and packaged, the crease lines 24, 26, 28, and 30 are normally folded at 90 degrees to form a rectangular tubular body as shown in FIG. 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, paste is applied to the back surface of the outer lid piece 42 or the surface of the inner lid piece 60, and the inner lid piece 60 is folded into the crease line 62. The outer lid piece 42 is folded forward at 90 degrees along the crease line 44, and the back surface of the outer lid piece 42 and the surface of the inner lid piece 60 are glued. By this operation, the bottom end portion of the cylindrical body is closed. Thereafter, a product such as a medicine is inserted inward from the open end on the top side of the cylindrical body.

次に、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、外蓋片３２の裏面または内蓋片５４の表面に糊を塗布し、内蓋片５４を折罫線５６で９０度に正折りし、外蓋片３２を折罫線３４で９０度に正折りし、外蓋片３２の裏面と内蓋片５４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３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４に示す天面側の断面図のように封止された構造となる。なお、上記とは逆に、先に天面側の蓋片を閉じて、底面側から商品を入れた後、底面側の蓋片を閉じても良い。   Next, 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 paste is applied to the back surface of the outer lid piece 32 or the surface of the inner lid piece 54. The outer cover piece 32 is normally folded at 90 degrees along the crease line 56, and the outer lid piece 32 is folded forward at 90 degrees along the crease line 34, and the back surface of the outer lid piece 32 and the surface of the inner lid piece 54 are glued. By this operation, the end on the top surface side of the tubular body is closed, and the state shown in FIG. In this state, the top surface side and the bottom surface side are sealed as shown in the sectional view of the top surface side shown in FIG. Contrary to the above, the lid on the top side may be closed first, and after putting the product from the bottom side, the lid on the bottom side may be closed.

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５（ａ）（ｂ）に示すように、正面板１４の透孔３８を指で押し込んで裏面板２２の押圧吸収部７４を内側に僅かに押し込む。この状態で、破断線３６で囲まれた開封部４０と押圧吸収部７４との間に僅かに隙間ができ、開封部４０の端縁に指を掛ける。そして、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破断線３６を破断させ、内蓋片５４及び外蓋片３２を開く。このとき、開封部４０は折罫線３４を介して外蓋片３２と連続し、且つ、外蓋片３２及び内蓋片５４が互いに糊付され、開封部４０、外蓋片３２及び内蓋片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。   The operation of opening and resealing the packaging box 10 is performed as follows. When opening, first, as shown in FIGS. 5 (a) and 5 (b), the through hole 38 of the front plate 14 is pushed in with a finger, and the pressure absorbing portion 74 of the back plate 22 is pushed slightly inward. In this state, a slight gap is formed between the opening portion 40 surrounded by the breaking line 36 and the pressure absorbing portion 74, and a finger is put on the edge of the opening portion 40. Then, with the finger placed on the opening portion 40, the breaking line 36 is broken by pulling upward, and the inner lid piece 54 and the outer lid piece 32 are opened. At this time, the opening portion 40 is continuous with the outer lid piece 32 through the crease line 34, and the outer lid piece 32 and the inner lid piece 54 are glued together, and the opening portion 40, the outer lid piece 32, and the inner lid piece. Since 54 is integrated, there is no part separated from the main body, and no dust or the like is generated.

なお、開封時に透孔３８で開封部４０の端縁を摘み、そのまま引き上げて開封しても良く、逆に開封部４０を箱体内側に押圧して、破断線３６を破り、開封しても良く、開封方法は問わない。   In addition, the edge of the opening part 40 may be picked by the through-hole 38 at the time of opening and may be lifted and opened as it is, or conversely, the opening part 40 may be pressed toward the inside of the box to break the breaking line 36 and open it.
