Description

本発明は、運搬時や保管時等において被梱包物を保護するための梱包箱に関する。   The present invention relates to a packaging box for protecting an object to be packed during transportation or storage.

プリンターや複合機等の画像形成装置や画像形成装置を構成する部品等を運搬したり保管したりする際には、段ボール等の梱包材料によって形成されるＡ式の梱包箱が用いられる場合が多い。Ａ式の梱包箱とは、箱状の本体部の開口を、折り畳み式のフラップで開閉する形状の箱であり、比較的安価であるので、広く使用されている。   When transporting or storing an image forming apparatus such as a printer or a multifunction peripheral, or parts constituting the image forming apparatus, an A-type packaging box formed of a packaging material such as cardboard is often used. . The A-type packing box is a box having a shape in which an opening of a box-shaped main body is opened and closed with a folding flap, and is widely used because it is relatively inexpensive.

このようなＡ式の梱包箱から被梱包物を取り出す際には、フラップを外側に折り曲げて本体部の開口を開き、本体部と被梱包物との間の隙間に手を入れて被梱包物を把持して本体部から上方に持ち上げる。この際、本体部と被梱包物との間の隙間が狭いと、この狭い空間に無理やりに手を入れる必要があるため、被梱包物の取り出しが困難となる。また、無理やり手を入れようとすると、被梱包物が損傷するような事態にもなり得る。   When taking out the object to be packed from such a type A packing box, the flap is folded outward to open the opening of the main body, and the hand is put in the gap between the main body and the packed object. Is gripped and lifted upward from the main body. At this time, if the gap between the main body portion and the article to be packed is narrow, it is necessary to force the narrow space to remove the article to be packed. Moreover, if it tries to put a hand forcibly, the situation to be packed may be damaged.

そこで、特許文献１には、被梱包物の取り出し時に手を挿入するための開口を形成した梱包箱が提案されている。開口は、対向する一対の側板と、この側板に連接されるフラップとの間に、ミシン目に沿って切り取って折り曲げることにより形成されるようになっており、この開口を通して被梱包物の底部に手を掛けて、被梱包物を持ち上げることができる。   Therefore, Patent Document 1 proposes a packaging box in which an opening for inserting a hand when a packaged item is taken out is formed. The opening is formed by cutting and bending along a perforation between a pair of opposing side plates and a flap connected to the side plate. You can hang your hands and lift the items to be packed.

特開２００７−２５３９７３号公報JP 2007-253974 A

しかしながら特許文献１に開示されている梱包箱においては、被梱包物の底部に手を掛けやすくなるが、被梱包物を梱包箱の高さだけ真上に持ち上げる必要があるので、被梱包物が重い場合には作業者に係る負担が大きくなる。また、開口を設けるために梱包箱にミシン目を形成しているので、梱包箱を積載した際の圧縮強度が低下する虞がある。梱包箱の強度を高めるためには、高強度の材質の梱包材料を使用したり、補強用の枠部材を別途設けたりする必要があるので、コストアップとなってしまう。   However, in the packaging box disclosed in Patent Document 1, it is easy to place a hand on the bottom of the packaged item, but since it is necessary to lift the packaged product just above the height of the packaged box, When it is heavy, the burden on the worker increases. Moreover, since the perforation is formed in the packaging box in order to provide the opening, there is a possibility that the compressive strength when the packaging box is loaded is lowered. In order to increase the strength of the packaging box, it is necessary to use a high-strength packaging material or to separately provide a reinforcing frame member, which increases costs.

本発明は上記事情を考慮し、高い圧縮強度を有し、さらに、被梱包物を取り出しやすい梱包箱を提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide a packaging box having high compressive strength and capable of easily taking out an object to be packed.

本発明の梱包箱は、前後方向に対向する一対の前後側板と、左右方向に対向する一対の左右側板とからなり、上下端に開口を有する四角筒状の外筒体と、上下方向に対向する天板及び底板と、前後方向又は左右方向に対向する一対の側板とからなる四角筒状の内筒体と、を備え、前記内筒体に被梱包物を収容した後、前記外筒体に前記内筒体を前記開口を通して嵌合させ、前記外筒体と前記内筒体とを連結することにより前記被梱包物が梱包されることを特徴とする。   The packaging box according to the present invention includes a pair of front and rear side plates facing in the front-rear direction and a pair of left and right side plates facing in the left-right direction, and is opposed to the square cylindrical outer cylinder having openings at the upper and lower ends, and the vertical direction. A rectangular cylindrical inner cylinder comprising a top plate and a bottom plate, and a pair of side plates facing in the front-rear direction or the left-right direction, and after the packaged article is accommodated in the inner cylinder, the outer cylinder The package is packed by fitting the inner cylinder through the opening and connecting the outer cylinder and the inner cylinder.

このような構成を採用することにより、梱包箱を開梱する際には、内筒体と外筒体との連結を解除した後で外筒体を内筒体から引き抜けば、被梱包物を内筒体から横方向に取り出すことができる。したがって、被梱包物を梱包箱の高さに持ち上げる必要がなくなり、開梱作業の負担を低減できる。また、梱包する際にも、被梱包物を横方向から内筒体に収容すればよいので、被梱包物を梱包箱の高さに持ち上げる必要がなく、梱包作業の負担も低減できる。   By adopting such a configuration, when unpacking the packing box, if the outer cylinder is pulled out of the inner cylinder after releasing the connection between the inner cylinder and the outer cylinder, Can be taken out from the inner cylinder in the lateral direction. Therefore, it is not necessary to lift the packaged item to the height of the packaging box, and the burden of unpacking work can be reduced. Further, when packing, it is only necessary to store the packed object in the inner cylinder from the lateral direction, so it is not necessary to lift the packed object to the height of the packing box, and the burden of packing work can be reduced.

以下、図面を参照しつつ本発明の一実施形態に係る梱包箱について説明する。   Hereinafter, a packaging box according to an embodiment of the present invention will be described with reference to the drawings.

本発明の一実施形態に係る梱包箱について、図１〜３を参照して説明する。図１は梱包箱の斜視図、図２は梱包箱の分解斜視図、図３Ａは外筒体の展開図、図３Ｂは内筒体の展開図である。以下の説明において、上下左右前後の方向は、各図に示す上下左右前後方向を指す。   A packaging box according to an embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view of the packaging box, FIG. 2 is an exploded perspective view of the packaging box, FIG. 3A is a development view of the outer cylinder, and FIG. 3B is a development view of the inner cylinder. In the following description, the up / down / left / right / front / rear directions refer to the up / down / left / right / front / rear directions shown in the drawings.

梱包箱１は、図１に示されるように、四角筒状の外筒体１０と、外筒体１０に嵌合可能な四角筒状の内筒体２０と、を有する。外筒体１０と内筒体２０とは、段ボール等の梱包材料で形成されている。   As illustrated in FIG. 1, the packaging box 1 includes a rectangular cylindrical outer cylinder 10 and a rectangular cylindrical inner cylinder 20 that can be fitted to the outer cylindrical body 10. The outer cylinder 10 and the inner cylinder 20 are formed of a packaging material such as cardboard.

外筒体１０は、図２に示されるように、前後方向に対向する一対の前後側板１０ａ、１０ｂと、左右方向に対向する一対の左右側板１０ｃ、１０ｄとからなり、上下端に開口１０ｅ、１０ｆが形成された四角筒状の形状を有する。前後側板１０ａ、１０ｂ及び左右側板１０ｃ、１０ｄは、それぞれ略正方形状の平面形状を有し、上下の開口１０ｅ、１０ｆも略正方形の形状を有する。左右の側板１０ｃ、１０ｄには、それぞれの下辺に沿って２個の横長長円状の長孔１１（開口部）が形成されている。   As shown in FIG. 2, the outer cylinder 10 includes a pair of front and rear side plates 10 a and 10 b facing in the front-rear direction, and a pair of left and right side plates 10 c and 10 d facing in the left-right direction. 10f has a square cylindrical shape. The front and rear side plates 10a and 10b and the left and right side plates 10c and 10d each have a substantially square planar shape, and the upper and lower openings 10e and 10f also have a substantially square shape. In the left and right side plates 10c and 10d, two oblong holes 11 (openings) having a horizontally long oval shape are formed along the respective lower sides.

外筒体１０は、図３Ａに示されるように、一枚の長方形状の段ボールを、４本の短手方向に延びる折り線１３を介して折り曲げて、端縁１４を突き合わせた接続部１５を粘着テープ１６で接続することによって形成されている。この際、接続部１５が左側板１０ｃのほぼ中央に位置するように段ボールが折り曲げられている。なお、段ボールは、波型に成型された中芯部の中空部が延びる方向（段ボールの目の方向）が、短手方向（図３Ａの矢印Ａで示す）となるように成形されており、各折り線１３及び端縁１４は目の方向と平行となっている。このように形成することにより、外筒体１０において、段ボールの目の方向は上下方向となっている。   As shown in FIG. 3A, the outer cylindrical body 10 is formed by bending a rectangular corrugated cardboard via four folding lines 13 extending in the short direction, and connecting portions 15 that abut the end edges 14. It is formed by connecting with an adhesive tape 16. At this time, the corrugated cardboard is bent so that the connecting portion 15 is positioned substantially at the center of the left side plate 10c. Incidentally, the corrugated cardboard is shaped so that the direction in which the hollow part of the core part molded into a corrugated shape extends (the direction of the corrugated cardboard eyes) is the short direction (indicated by the arrow A in FIG. 3A). Each fold line 13 and edge 14 are parallel to the eye direction. By forming in this way, in the outer cylinder 10, the direction of the corrugated cardboard is the vertical direction.

内筒体２０は、図２に示されるように、上下方向に対向する天板２０ａ及び底板２０ｂと、左右方向に対向する一対の左右側板２０ｃ、２０ｄとからなり、前後端に開口が形成された四角筒状の形状を有する。天板２０ａと、底板２０ｂと、左右側板２０ｃ、２０ｄとは、略正方形状の平面形状を有する。天板２０ａと底板２０ｂは、前後方向の寸法と左右方向の寸法とが、外筒体１０の上下の開口１０ｅ、１０ｆの内周における前後方向の寸法及び左右方向の寸法とほぼ等しい。左右側板２０ｃ、２０ｄは、上下方向の寸法が、外筒体１０の左右側板１０ｃ、１０ｄの上下方向の寸法とほぼ等しく、前後方向の寸法が、外筒体１０の上下の開口１０ｅ、１０ｆの内周における前後方向の寸法とほぼ等しい。このように形成することにより、内筒体２０は外筒体１０の上下の開口１０ｅ、１０ｆから外筒体１０に挿嵌可能となる。左右の側板２０ｃ、２０ｄは、それぞれの下辺に沿って２個の横長長円状の長孔２１が形成されている。これらの長孔２１は、内筒体２０が外筒体１０に挿嵌された際に、外筒体１０に形成された長孔１１と対応するように形成されている。   As shown in FIG. 2, the inner cylinder 20 includes a top plate 20 a and a bottom plate 20 b that face in the vertical direction, and a pair of left and right side plates 20 c and 20 d that face in the left and right direction, and an opening is formed at the front and rear ends. It has a square cylindrical shape. The top plate 20a, the bottom plate 20b, and the left and right side plates 20c and 20d have a substantially square planar shape. The top plate 20a and the bottom plate 20b have a front-rear dimension and a left-right dimension that are substantially equal to the front-rear dimension and the left-right dimension on the inner periphery of the upper and lower openings 10e, 10f of the outer cylinder 10. The left and right plates 20c and 20d have a vertical dimension that is substantially the same as the vertical dimension of the left and right side panels 10c and 10d of the outer cylinder 10, and the front and rear dimension is that of the upper and lower openings 10e and 10f of the outer cylinder 10. It is almost the same as the longitudinal dimension on the inner circumference. By forming in this way, the inner cylinder 20 can be inserted into the outer cylinder 10 through the upper and lower openings 10 e and 10 f of the outer cylinder 10. The left and right side plates 20c, 20d are formed with two oblong elongated holes 21 along the respective lower sides. These long holes 21 are formed so as to correspond to the long holes 11 formed in the outer cylindrical body 10 when the inner cylindrical body 20 is inserted into the outer cylindrical body 10.

内筒体２０は、図３Ｂに示されるように、一枚の長方形状の段ボールを、４本の短手方向に延びる折り線２３を介して折り曲げて、端縁２４を突き合わせた接続部２５を粘着テープ２６で接続することによって形成されている。この際、接続部２５が右側板２０ｄのほぼ中央に位置するように段ボールが折り曲げられている。なお、段ボールは、目の方向が長手方向（図３Ｂの矢印Ｂで示す）となるように成形されて、各折り線２３と端縁２４が目の方向と直交するようになっている。このように形成することにより、内筒体２０においても、段ボールの目の方向は上下方向となっている。   As shown in FIG. 3B, the inner cylinder 20 has a connecting portion 25 in which one rectangular corrugated cardboard is bent through four folding lines 23 extending in the short direction and the end edges 24 are abutted. It is formed by connecting with an adhesive tape 26. At this time, the corrugated board is bent so that the connecting portion 25 is positioned substantially at the center of the right side plate 20d. The corrugated cardboard is shaped so that the direction of the eyes is the longitudinal direction (indicated by an arrow B in FIG. 3B) so that each fold line 23 and the edge 24 are orthogonal to the direction of the eyes. By forming in this way, also in the inner cylinder 20, the direction of the corrugated cardboard is the vertical direction.

上記構成を有する梱包箱１で画像形成装置等の被梱包物３０を梱包する方法を、図４Ａ、図４Ｂ、図４Ｃを参照して説明する。梱包箱１は、被梱包物３０と梱包箱１との間に、３５ｍｍ〜５０ｍｍの隙間が開くように形成されている。最初に、被梱包物３０を内筒体２０に収容する。まず、図４Ａに示されるように、内筒体２０を形成する段ボールを展開した状態で準備し、内筒体２０の底板２０ｂとなる面に、緩衝材３１を介して被梱包物３０を載置する。さらに、被梱包物３０の上面と前後側面との角に、それぞれ緩衝材３１を介装させる。そして、図４Ｂに示されるように、段ボールを折り線２３で四角筒状に折り曲げて、被梱包物３０の上下面と左右側面を包囲し、段ボールの端縁２４を突き合わせた接続部２５を粘着テープ２６で接続する。   A method for packing an object 30 such as an image forming apparatus in the packing box 1 having the above configuration will be described with reference to FIGS. 4A, 4B, and 4C. The packaging box 1 is formed so that a gap of 35 mm to 50 mm is opened between the packaged item 30 and the packaging box 1. First, the article 30 is accommodated in the inner cylinder 20. First, as shown in FIG. 4A, the cardboard for forming the inner cylinder 20 is prepared in an unfolded state, and the object to be packed 30 is placed on the surface that becomes the bottom plate 20 b of the inner cylinder 20 via the cushioning material 31. Put. Furthermore, cushioning materials 31 are interposed at the corners of the upper surface and the front and rear side surfaces of the object to be packed 30. Then, as shown in FIG. 4B, the corrugated cardboard is folded into a quadrangular cylindrical shape along the fold line 23 to surround the upper and lower surfaces and the left and right side surfaces of the packaged item 30, and the connection portion 25 that abuts the edge 24 of the corrugated cardboard is adhered. Connect with tape 26.

一方で、外筒体１０を形成する段ボールを準備し、各折り線１３で四角筒状に折り曲げて、段ボールの端縁１４を突き合わせた接続部１５を粘着テープ１６で接続しておく。そして、左側板１０ｃに接続部１５が位置するように、外筒体１０を位置決めする。   On the other hand, a corrugated cardboard for forming the outer cylindrical body 10 is prepared, bent into a square cylinder shape at each fold line 13, and a connecting portion 15 that abuts the edge 14 of the corrugated cardboard is connected with an adhesive tape 16. And the outer cylinder 10 is positioned so that the connection part 15 may be located in the left side board 10c.

そして、図４Ｃの白抜き矢印で示すように、外筒体１０の下側の開口１０ｆから、被梱包物３０を収容した内筒体２０を外筒体１０に嵌合する。これにより、被梱包物３０の上下の面は、内筒体２０の天板２０ａと底板２０ｂで覆われ、被梱包物３０の前後の面は、外筒体１０の前後側板１０ａ、１０ｂで覆われ、被梱包物３０の左右の面は、内筒体２０の左右の側板２０ｃ、２０ｄ及び外筒体１０の左右の側板１０ｃ、１０ｄで覆われる。   4C, the inner cylinder 20 containing the article to be packed 30 is fitted into the outer cylinder 10 from the lower opening 10f of the outer cylinder 10. Thereby, the upper and lower surfaces of the package 30 are covered with the top plate 20a and the bottom plate 20b of the inner cylinder 20, and the front and rear surfaces of the package 30 are covered with the front and rear plates 10a and 10b of the outer cylinder 10. The left and right surfaces of the package 30 are covered with the left and right side plates 20 c and 20 d of the inner cylinder 20 and the left and right side plates 10 c and 10 d of the outer cylinder 10.

最後に、それぞれ重ねられた外筒体１０の左右の側板１０ｃ、１０ｄと内筒体２０の左右の側板２０ｃ、２０ｄとにおいて、並んだ長孔１１、２１にジョイント部材（図示されず）を装着して、内筒体２０の左右の側板２０ｃ、２０ｄと外筒体１０の左右の側板１０ｃ、１０ｄとをそれぞれ連結する。これにより、外筒体１０と内筒体２０とが連結されて、被梱包物３０が梱包箱１に梱包される。   Finally, joint members (not shown) are attached to the long holes 11 and 21 arranged on the left and right side plates 10c and 10d of the outer cylindrical body 10 and the left and right side plates 20c and 20d of the inner cylindrical body 20, respectively. Then, the left and right side plates 20c, 20d of the inner cylinder 20 and the left and right side plates 10c, 10d of the outer cylinder 10 are connected to each other. Thereby, the outer cylinder 10 and the inner cylinder 20 are connected, and the article 30 is packed in the packing box 1.

この梱包箱１を開梱する方法を説明する。最初に、外筒体１０と内筒体２０とを連結しているジョイント部材を取り外す。そして、外筒体１０を内筒体２０から引き抜く。または、粘着テープ１６を剥がして外筒体１０を開く。次に、内筒体２０の粘着テープ２６を剥がして内筒体２０を開く。これにより、被梱包物３０の上面と左右側面及び前後側面が露呈する。   A method for unpacking the packing box 1 will be described. First, the joint member connecting the outer cylinder 10 and the inner cylinder 20 is removed. Then, the outer cylinder 10 is pulled out from the inner cylinder 20. Or the adhesive tape 16 is peeled off and the outer cylinder 10 is opened. Next, the adhesive tape 26 of the inner cylinder 20 is peeled off and the inner cylinder 20 is opened. Thereby, the upper surface, left and right side surfaces, and front and rear side surfaces of the article 30 are exposed.

上記説明したように本実施形態に係る梱包箱１においては、開梱した際に被梱包物３０の上面と左右側面及び前後側面が露呈するので、緩衝材３１を取り外して被梱包物３０を把持しやすくなる。また、被梱包物３０を真上以外の方向にも持ち上げることができ、梱包箱１から取り出す際に、梱包箱１の高さだけ真上に持ち上げる必要がなくなる。さらに、梱包箱１に被梱包物３０を梱包する際にも、内筒体２０を形成する段ボールを展開して、底板２０ｂを形成する面に被梱包物３０を載置すればよいので、被梱包物３０を梱包箱１の高さだけ真上に持ち上げる必要がなく、作業に大きな負担がかからない。   As described above, in the packaging box 1 according to the present embodiment, the upper surface, the left and right side surfaces, and the front and rear side surfaces of the packaged object 30 are exposed when the package is unpacked. It becomes easy to do. Further, the object to be packed 30 can be lifted in a direction other than directly above, and when it is taken out from the packing box 1, it is not necessary to lift it right above the packing box 1. Furthermore, when packing the packing object 30 in the packing box 1, the cardboard forming the inner cylinder 20 is developed and the packing object 30 is placed on the surface on which the bottom plate 20b is formed. It is not necessary to lift the package 30 just above the height of the packaging box 1, and a large burden is not imposed on the work.

また、開梱後に梱包箱１を折り畳む際にも、外筒体１０と内筒体２０とは、平面状に展開されているので、それぞれ折り線１３、２３に沿ってコンパクトに折り畳むことができる。   Further, when the packaging box 1 is folded after unpacking, the outer cylinder body 10 and the inner cylinder body 20 are developed in a flat shape, so that they can be folded compactly along the folding lines 13 and 23, respectively. .

さらに、梱包箱１の左右の側面は、内筒体２０の左右の側板２０ｃ、２０ｄと外筒体１０の左右の側板１０ｃ、１０ｄとが重なった二重の構造となっているので、上下方向における梱包箱１の圧縮強度が高くなる。このため、Ａ式の梱包箱のように側板が重なっていない梱包箱に比べて１．２〜１．５倍の圧縮強度を得ることができる。なお、内筒体２０は、天板２０ａ及び底板２０ｂと、前後方向において対向する前後側板と、によって四角筒状に形成してもよい。この場合は、内筒体２０の前後の側板と外筒体１０の前後の側板１０ａ、１０ｂとが重なった二重の構造となる。   Further, the left and right side surfaces of the packaging box 1 have a double structure in which the left and right side plates 20c and 20d of the inner cylinder 20 and the left and right side plates 10c and 10d of the outer cylinder 10 overlap each other. The compressive strength of the packaging box 1 becomes higher. For this reason, it is possible to obtain a compressive strength 1.2 to 1.5 times that of a packing box in which side plates do not overlap each other like an A-type packing box. In addition, you may form the inner cylinder 20 in the shape of a square cylinder by the top plate 20a and the bottom plate 20b, and the front and rear side plates facing each other in the front-rear direction. In this case, a double structure in which the side plates before and after the inner cylinder 20 and the side plates 10a and 10b before and after the outer cylinder 10 overlap each other is formed.

さらに、外筒体１０と内筒体２０とは、それぞれ段ボールの目の方向が上下方向となるように形成されているので、上下方向においてより高い強度を得ることができる。   Furthermore, since the outer cylinder 10 and the inner cylinder 20 are formed such that the direction of the corrugated cardboard is in the vertical direction, higher strength can be obtained in the vertical direction.

また、内筒体２０においてシート材料の端縁２４を接続した接続部２５が設けられた右側板２０ｄと、外筒体１０においてシート材料の端縁１４を接続した接続部１５が設けられた左側板１０ｃとが、左右方向において対向しているので、強度低下しやすい接続部２５、１５を分散して配置できる。このため、梱包箱１を積み上げた際にも、強度が局所的に低下しないので、安定に積み上げることができる。さらに、この接続部１５、２５が設けられた左右側板が二重になっているので、接続部１５、２５を設けたことによる強度低下を防ぐことができる。   Further, the right side plate 20d provided with the connecting portion 25 connected to the edge 24 of the sheet material in the inner cylinder 20 and the left side provided with the connecting portion 15 connected to the edge 14 of the sheet material in the outer cylinder 10 are provided. Since the plate 10c is opposed in the left-right direction, the connection portions 25 and 15 that are likely to be reduced in strength can be dispersedly arranged. For this reason, even when the packaging boxes 1 are stacked, the strength does not decrease locally, so that they can be stacked stably. Furthermore, since the left and right side plates provided with the connection portions 15 and 25 are double, it is possible to prevent a decrease in strength due to the provision of the connection portions 15 and 25.

なお、外筒体１０の接続部１５の位置は、左側板１０ｃに限定されず、他の側板や、隣り合う側板の角に設けても良い。また、内筒体２０の接続部２５の位置も、右側板２０ｄに限定されず、上板２０ａ又は左側板２０ｃに設けても良い。   In addition, the position of the connection part 15 of the outer cylinder 10 is not limited to the left side plate 10c, and may be provided at the corner of another side plate or an adjacent side plate. Further, the position of the connecting portion 25 of the inner cylinder 20 is not limited to the right side plate 20d, and may be provided on the upper plate 20a or the left side plate 20c.

さらに、内筒体２０は外筒体１０に嵌合されるので、内筒体２０の天板２０ａ及び底板２０ｂと左右の側板２０ｃ、２０ｄとは、段ボールの厚さを考慮した寸法だけ外筒体１０の各側板よりも寸法が小さく形成されている。このため、一般的な同サイズのＡ式の梱包箱に比べて必要なシート材料の面積を狭くすることができる。   Furthermore, since the inner cylinder 20 is fitted to the outer cylinder 10, the top plate 20a and the bottom plate 20b of the inner cylinder 20 and the left and right side plates 20c and 20d have an outer cylinder of a dimension that takes into account the thickness of the cardboard. The dimension is smaller than each side plate of the body 10. For this reason, the area of a required sheet material can be narrowed compared with the general A-type packaging box of the same size.

図５は、本実施形態の梱包箱１と一般的なＡ式の梱包箱４０との展開図を重ねて示した図であり、実線は本実施形態の梱包箱の展開図を示し、二点鎖線はＡ式の梱包箱の展開図を示す。図５に示されるように、ハッチングで示される部分Ｒと、図５の上下の辺と右辺とに沿った部分と、Ａ式梱包箱４０の接着代の部分だけ、Ａ式の梱包箱に比べて使用面積を狭くできるので、材料費を低減できる。また、Ａ式梱包箱４０のようにフラップを形成するための切り欠き部を形成する必要がないので、段ボール等の梱包材料からの成形が容易である。   FIG. 5 is a diagram in which development views of the packaging box 1 of this embodiment and a general A-type packaging box 40 are overlapped, and a solid line shows a development view of the packaging box of this embodiment. A chain line shows a development view of the A-type packing box. As shown in FIG. 5, only the portion R shown by hatching, the portion along the upper and lower sides and the right side of FIG. 5, and the bonding margin portion of the A-type packaging box 40 are compared with the A-type packaging box. Thus, the material area can be reduced because the use area can be reduced. Moreover, since it is not necessary to form the notch part for forming a flap like the A type packaging box 40, the shaping | molding from packaging materials, such as corrugated cardboard, is easy.
