Description
本考案は、包装箱に関する。 The present invention relates to a packaging box.
従来、段ボール板紙等で形成された直方体形状の包装箱は、被包装物を取り出した後にリサイクル或いは廃棄するために、偏平に折り畳むことが行われる。具体的には、包装箱の上下のフラップを開いて四角筒状の胴部の一方の対角線上に対向する両角部を鋭角に折り曲げることにより、胴部の側壁を重ねるようにして偏平に畳み込む。 2. Description of the Related Art Conventionally, a rectangular parallelepiped packaging box formed of corrugated paperboard or the like is folded flatly for recycling or disposal after taking out an article to be packaged. Specifically, the upper and lower flaps of the packaging box are opened and the opposite corners of the rectangular cylindrical barrel are bent at an acute angle so that the side wall of the barrel is overlapped and folded flat.
しかし、包装箱が段ボール板紙等の曲げこわさの比較的大きい材料で形成されている場合には、復元力が作用して胴部の側壁を重ねた状態から浮き上がりやすく、偏平に折り畳んだ状態が維持されないことがある。このため、使用後に偏平に畳んだ複数の包装箱を積み重ねた状態で保管や移動を行うときに、安定した積み重ね状態が得られず、取り扱いが煩わしいという不都合がある。 However, if the packaging box is made of a material with a relatively large bending stiffness such as corrugated paperboard, it will be easy to lift from the state where the side wall of the body part is piled up due to the restoring force, and the flat folded state will be maintained It may not be done. For this reason, there is an inconvenience that when a plurality of packaging boxes folded flat after use are stored or moved in a stacked state, a stable stacked state cannot be obtained and handling is troublesome.
そこで、従来、胴部の上縁に連接されているフラップを用いて胴部を偏平に畳んだ状態を維持するようにした包装箱が知られている（下記特許文献１参照）。 Therefore, conventionally, a packaging box is known that maintains a state in which the body is folded flat using a flap connected to the upper edge of the body (see Patent Document 1 below).
この包装箱は、平面視長方形状の胴部の上縁のうち、短辺となる一対の上縁に内フラップが連設され、長辺となる一対の上縁に外フラップが連設されている。一方の外フラップには、その先端から基端に向かって切込みを設けることにより係止片が形成されている。そして、胴部を偏平に畳んだとき、他方の外フラップの側端部を切込みに差し込み、係止片を他方の外フラップの側端部とこの外フラップに隣合う内フラップとの間の隙間で互い違いに係止させ、胴部を折り畳んだ状態を維持させるようになっている。 In this packaging box, an inner flap is connected to a pair of upper edges that are short sides, and an outer flap is connected to a pair of upper edges that are long sides among the upper edges of a rectangular body in plan view. Yes. On one outer flap, a locking piece is formed by providing a cut from the front end to the base end. When the body is folded flat, the side end of the other outer flap is inserted into the notch, and the locking piece is inserted between the side end of the other outer flap and the inner flap adjacent to the outer flap. In this way, the body is folded and kept in a folded state.
しかし、前記係止片を形成するための切込みは、一方の外フラップの先端から基端に亘って設けられているため、他方の外フラップの側端部を切込んでも、その係止力は極めて小さい。そして、畳んだときに鋭角に折り曲げられた胴部の角部の復元力が大きく、胴部の側壁が重なった状態から浮き上がると、両外フラップが胴部が浮き上がる方向に抵抗なく折れ曲がり、それに伴って外フラップ同士の係合が解除されてしまうことがある。 However, since the notch for forming the locking piece is provided from the front end to the base end of one outer flap, even if the side end of the other outer flap is cut, the locking force is Very small. Then, when the body is folded, it has a great restoring force at the corner of the body that is bent at an acute angle. The engagement between the outer flaps may be released.
また、外フラップにその先端から基端にかけて切込みを形成すると外フラップの強度が低下するおそれもある。 In addition, if a cut is formed in the outer flap from its distal end to the proximal end, the strength of the outer flap may be reduced.
上記の点に鑑み、本考案は、フラップ等の強度低下を抑えて、胴部が偏平に折り畳まれた状態を確実に維持することができる包装箱を提供することを目的とする。 In view of the above-described points, an object of the present invention is to provide a packaging box that can reliably maintain a state in which a body portion is flatly folded while suppressing a decrease in strength of a flap or the like.
本考案は、４つの角部を介して連なる４つの側板により形成されて長方形に開口する筒状の胴部と、該胴部の開口端縁のうち長辺となる端縁を有する第１側板に折目線を介して連設されて該第１側板に対し直角となるように胴部内側方向に折り曲げる一対の長辺フラップと、前記胴部の開口端縁のうち短辺となる端縁を有する第２側板に折目線を介して連設されて該第２側板に対し直角となるように胴部内側方向に折り曲げる一対の短辺フラップとを備え、該短辺フラップに把持孔が形成されており、該把持孔に対応する凹部が各長辺フラップの先端部に形成されている包装箱であって、両長辺フラップ及び両短辺フラップを開いて前記胴部の対向する一対の角部を共に鋭角に曲げることにより該胴部を偏平に畳んだとき、両長辺フラップの一部同士が重合するものにおいて、前記長辺フラップの先端部に形成したＬ字形の切れ目により、長辺フラップの折り曲げ方向に交差する方向に折り起こし自在とされた折起し片を設け、一方の長辺フラップの前記折起し片を折り起こすことにより、該折起し片の第１側板側の端縁と他方の長辺フラップの前記凹部の奥端縁とが互いに摩擦係合して胴部の折り畳み状態が維持されることを特徴とする。 The present invention is a first side plate having a cylindrical body portion that is formed by four side plates that are connected via four corners and that is open in a rectangular shape, and an end edge that is a long side of the opening edge of the body portion. A pair of long side flaps that are connected to each other through a crease line and bend toward the inner side of the body so as to be perpendicular to the first side plate, and an edge that is a short side of the opening edge of the body. A pair of short side flaps that are connected to the second side plate via a crease line and bend inwardly of the body so as to be perpendicular to the second side plate, and a gripping hole is formed in the short side flap. And a recess corresponding to the gripping hole is formed at the front end of each long side flap, and the pair of corners of the trunk portion facing each other by opening both long side flaps and both short side flaps. When the body is folded flat by bending both parts at an acute angle, both long side flaps In the one where the parts overlap each other, the L-shaped cut formed at the tip of the long side flap is provided with a folded piece that can be folded in a direction intersecting the folding direction of the long side flap, By folding the folded piece of the long side flap, the end edge on the first side plate side of the folded piece and the back end edge of the concave portion of the other long side flap are frictionally engaged with each other. The folded state of the part is maintained.
本考案によれば、長辺フラップの先端部に折起し片を設け、胴部が偏平に畳まれて両長辺フラップの一部同士が重合したとき、一方の長辺フラップの折起し片を折り起こすことで、折起し片の端縁を他方の長辺フラップの凹部の奥端縁に摩擦係合するので、胴部を偏平に折り畳んだ状態を確実に維持させることができる。 According to the present invention, when the long side flap is folded at the tip of the long side flap and the body part is folded flatly and a part of both long side flaps are overlapped, one long side flap is folded. By folding the piece, the end edge of the folded piece is frictionally engaged with the back end edge of the concave portion of the other long side flap, so that the state where the body portion is folded flat can be reliably maintained.
そして、この折起し片を形成するＬ字形の切れ目は、比較的小さな領域である長辺フラップの先端部に設けられているので、長辺フラップの強度は殆ど低下しない。 And since the L-shaped cut which forms this folding piece is provided in the front-end | tip part of the long side flap which is a comparatively small area | region, the intensity | strength of a long side flap hardly falls.
また、本考案においては、前記短辺フラップの先端角部に、該短辺フラップの先端縁から側端縁に至る折目線を介して折り曲げ自在の摘み片を設け、前記短辺フラップは、その先端角部の前記摘み片以外の位置で前記長辺フラップの外面に接着されることが好ましい。 Further, in the present invention, a pinch that is foldable via a crease line extending from the leading edge of the short side flap to the side edge is provided at the corner of the tip of the short side flap. It is preferable to adhere to the outer surface of the long side flap at a position other than the knob at the tip corner.
これによれば、短辺フラップが長辺フラップに接着されて胴部を閉塞していても、胴部を偏平に折り畳むときに、摘み片を摘んで短辺フラップを長辺フラップから剥離させることができ、胴部の折り畳み作業が容易となる。 According to this, even when the short side flap is adhered to the long side flap and the trunk portion is closed, when the trunk portion is folded flat, the knob is picked and the short side flap is peeled off from the long side flap. This makes it easy to fold the trunk.
そして、本考案は、前記第２側板は、破断することにより胴部の一部を開口させる破断開口部を備え、該破断開口部は、前記第２側板の一側縁側の一部を破断する第１破断可能部と、該第１破断可能部の一部に接して前記第２側板の他側縁側の一部を破断する第２破断可能部とによって構成される包装箱に工程に採用することができる。 In the present invention, the second side plate includes a break opening portion that opens a part of the body portion by breaking, and the break opening portion breaks a part of one side edge side of the second side plate. It is employed in the process for a packaging box composed of a first breakable part and a second breakable part that is in contact with a part of the first breakable part and breaks a part of the other side edge of the second side plate. be able to.

According to this, it is possible to reliably prevent the strength of the inner flaps 7 and 8 from being lowered due to the folds and the cut k of the piece 17 being provided.
次に、包装箱１の開梱作業を説明する。図１を参照して、先ず、第１破断可能部１２を包装箱１の内側に向かって押圧して破断可能線ｈ１，ｈ２，ｈ３を破断し、天板６から遊離させる。これにより、破断可能線ｈ３に接する第２破断可能部１３の破断端縁が露出する。 Next, the unpacking operation of the packaging box 1 will be described. With reference to FIG. 1, first, the first breakable portion 12 is pressed toward the inner side of the packaging box 1 to break the breakable lines h <b> 1, h <b> 2, h <b> 3 and release them from the top plate 6. Thereby, the breaking edge of the 2nd breakable part 13 which contact | connects the breakable line h3 is exposed.
次いで、第２破断可能部１３を上方に引き上げ、破断可能線ｈ６，ｈ７から破断可能線ｈ４，ｈ５に沿って破断する。これにより、図３に示すように、第２破断可能部１３が天板６から遊離して胴部１９の上部が開放され、被包装物の取出しが行なえる状態に開梱される。 Next, the second breakable portion 13 is pulled upward and is broken from the breakable lines h6 and h7 along the breakable lines h4 and h5. As a result, as shown in FIG. 3, the second breakable portion 13 is released from the top plate 6, the upper portion of the body portion 19 is opened, and the unpacked object can be unpacked.
次に、被包装物を取出した後の包装箱１の解体折り畳み作業を説明する。図３に示す状態から、先ず、外フラップ９,１０の先端角部の摘み片１４を摘んで、外フラップ９,１０を内フラップ７，８の外面から外方に引き剥がす。外フラップ９,１０に摘み片１４を設けたことにより、内フラップ７，８から外フラップ９,１０を分離させる作業が容易となる。 Next, the dismantling / folding operation of the packaging box 1 after taking out the article to be packaged will be described. From the state shown in FIG. 3, first, the knob 14 at the tip corner of the outer flaps 9, 10 is picked and the outer flaps 9, 10 are peeled outward from the outer surfaces of the inner flaps 7, 8. By providing the knobs 14 on the outer flaps 9 and 10, the operation of separating the outer flaps 9 and 10 from the inner flaps 7 and 8 is facilitated.
次いで、外フラップ９,１０を開き、四角筒状の胴部１９の一方の対角線上に対向する両角部を鋭角に折り曲げることにより、図４に示すように、包装箱１は、偏平に折り畳まれる。このとき、本実施形態の包装箱１は、開梱された状態で第２破断可能部１３が天板６から分離して容易にシート状にすることができるので、扁平に折り畳む作業が極めて円滑に行える。 Next, the outer flaps 9 and 10 are opened, and the opposite corners of the rectangular cylindrical body 19 are folded at an acute angle, whereby the packaging box 1 is folded flat as shown in FIG. . At this time, the packaging box 1 according to the present embodiment can be easily formed into a sheet shape by separating the second breakable portion 13 from the top plate 6 in the unpacked state, so that the flat folding operation is extremely smooth. Can be done.
その後、図４及び図５に示すように、内フラップ７の凹部１６に対応して位置する内フラップ８の折起し片１７を、内フラップ７の凹部１６に入る方向に折り起こす。このとき、折起し片１７の折り起こし方向は、胴部１９を閉塞する際の内フラップ８の折り曲げ方向に交差する方向となる。 Thereafter, as shown in FIGS. 4 and 5, the folded piece 17 of the inner flap 8 positioned corresponding to the recessed portion 16 of the inner flap 7 is folded in a direction to enter the recessed portion 16 of the inner flap 7. At this time, the folding direction of the folded piece 17 is a direction intersecting with the folding direction of the inner flap 8 when the body portion 19 is closed.
こうすることにより、図５に示すように、折起し片１７の端縁１７ａが内フラップ７の凹部１６の奥端縁１６ａに摩擦係合し、図４に示すように、包装箱１の偏平に折り畳まれた状態が強固に維持される。 By doing so, as shown in FIG. 5, the end edge 17a of the folded piece 17 is frictionally engaged with the inner end edge 16a of the recess 16 of the inner flap 7, and as shown in FIG. The flatly folded state is firmly maintained.
