Japanese Patent Application 2001-97358

このように、特許文献１の発明は、箱をダンボールで形成するものであるから、その弾性力によって特定の形状を保持させることができる。
しかし、通常の包装用箱のように、ダンボールよりも柔軟性のある厚手の紙で作られた箱では、その柔軟性により、特定の形状を保持し難くなる。 Thus, since the invention of Patent Document 1 forms a box with corrugated cardboard, a specific shape can be held by its elastic force.
However, a box made of thick paper that is more flexible than cardboard, such as a normal packaging box, makes it difficult to maintain a specific shape due to its flexibility.

そこで、本発明は、これらの問題点を解消すべく、ダンボールよりも柔軟性のある厚手の紙で作られ、折り畳み可能であり、箱状態にしたとき蓋体が開いた状態または閉じた状態が維持できる包装用箱の提供を課題とするものである。 Therefore, in order to solve these problems, the present invention is made of thick paper that is more flexible than corrugated cardboard, and can be folded. An object is to provide a packaging box that can be maintained.

ここで、４側面からなる箱本体の特定の側面から連続的に形成された蓋体は、前記特定の側面に隣接する側面よりも長い側面に形成すると、不要とする紙の切り捨て面積を少なくすることができる。しかし、短い側面に形成することを否定するものではない。
また、上記蓋体側面から突出形成した凸部と上記蓋体側面に形成した切溝において、凸部はその紙面の有効的利用からして、接触抵抗の大きい略長方形とするのが望ましい。また、切溝については、直線状でもよいが、彎曲させて凸片部との接触面積を広くするのが好適である。結論的には、いずれも意匠性を考慮できる。
そして、上記箱本体の蓋体を連続的に形成した側面に対向する側面と重なり合う蓋体側面は、その対向する側面と重なり合う面は、意匠性を考慮して決定できる。
更に、上記蓋体側面に突出するように切曲形成し、上記蓋体側面に形成した切溝に挿脱自在な凸片部は、略コ字状、略Ｕ字状に切り起し溝を入れて形成したものであればよい。
なお、ここで、切溝とは、単に、直線状または曲線状に切ったものであり、また、切り起し溝は、複数の直線にて凸状または曲線状に切った結果、舌片を形成したものである。 The packaging box according to claim 1 is a box body composed of four side surfaces of a short side surface and a long side surface, a lid formed on a specific long side surface of the box body, A lid body side surface formed on the lid body and overlapped with a side surface on the long side facing the box body by bending, a protrusion formed protruding from the side surface of the lid body, and a cut formed on the side surface of the lid body. A groove and a cut formed on the side of the long side opposite to the side of the long side where the lid of the box body is formed, and the protrusion protruding from the side of the lid is detachable. A bottom surface formed continuously from any of the raised groove and the convex piece portion and the side surface on the long side, and formed at a distance to the side surface on the long side on the opposite side, and a free end side of the bottom surface One or more engaging protrusions formed on the bottom and the bottom surface that accommodates the engaging protrusions formed on the bottom. The notch portion formed on the long side surface facing the long side surface and the other long side surface are continuously formed to the long side surface on the opposite side. A bottom surface formed on the short side surface, a bottom piece formed on the short side surface, and a bottom piece formed on the short side surface. A fold line is formed so that it can be folded at 45 degrees from the lower side of the side surface on the side, and the fold line is folded in an adhesive state by joining the outside of the fold line to each of the bottom surfaces with a margin of glue. The four sides of the box body are parallel, and when the fold line is not folded in the bonded state, the box body is rectangular, and the four sides of the short side and the long side are Is a right angle to the bottom piece
Here, if the cover body continuously formed from the specific side surface of the box body having four side surfaces is formed on the side surface longer than the side surface adjacent to the specific side surface, the unnecessary paper cut-off area is reduced. be able to. However, it does not deny forming on the short side.
Moreover, in the convex part protrudingly formed from the said cover body side surface and the kerf formed in the said cover body side surface, it is desirable to make a convex part into a substantially rectangular with a large contact resistance from the effective use of the paper surface. Further, the kerf may be linear, but it is preferable to bend it to widen the contact area with the convex piece. In conclusion, design properties can be considered in any case.
And the side surface which overlaps the side surface which opposes the side surface which formed the cover body of the said box main body continuously formed can determine the surface which overlaps the side surface which opposes in consideration of design property.
Further, the convex piece portion that is cut and formed so as to protrude on the side surface of the lid body and can be inserted into and removed from the groove formed on the side surface of the lid body is cut and raised into a substantially U shape and a substantially U shape. What is necessary is just to form it.
Here, the kerf is simply cut into a straight line or a curved line, and the cut and raised groove is cut into a convex or curved line with a plurality of straight lines. Formed.

また、箱本体の底面の対向側面までの距離に形成された底部は、前記特定の側面に隣接する側面よりも長い側面に形成すると、不要とする紙の切り捨て面積を少なくすることができる。
そして、上記１個以上の係合凸部とは、略長方形の突出形状または鍵形（略Ｌ字状）の突出形状とすることができ、好ましくは、容易に切欠部から離脱しない構造であればよい。 Further, if the bottom portion formed at a distance to the opposite side surface of the bottom surface of the box body is formed on a side surface longer than the side surface adjacent to the specific side surface, an unnecessary paper cutting area can be reduced .
Then, the above one or more engaging protrusion can be a protrusion shape of substantially rectangular projected shape or Kagigata (substantially L-shaped), preferably, without departing from readily notch structure there That's fine.

請求項１にかかる包装用箱は、４側面からなる箱本体の特定の側面から連続的に形成された蓋体の自由端側に折曲形成した蓋体側面は、前記箱本体の蓋体を連続的に形成した側面に対向する側面と重なり合い、前記蓋体側面から突出形成した凸部は前記側面に形成した切り起し溝に挿脱自在となる。同時に、前記側面に形成した凸片部は、前記蓋体側面の切溝に挿脱自在となる。
したがって、前記蓋体側面から突出形成した凸部が前記側面に形成した切り起し溝に挿入され、前記側面に形成した凸片部が前記蓋体側面の切溝に挿入されると、その接触抵抗及び弾性により、包装用箱の蓋体は閉じた状態を維持する。また、前記蓋体側面から突出形成した凸部が前記側面に形成した切り起し溝に挿入されていないとき、前記側面に形成した凸片部が前記蓋体側面の切溝に挿入されていないとき、包装用箱の蓋体は開いた状態を維持する。 The packaging box according to claim 1 is formed by bending the lid body side formed by bending the free end side of the lid body continuously formed from a specific side surface of the box body having four side surfaces. The convex part which overlaps with the side surface which faces the side surface formed continuously, and protrudes from the said cover body side surface becomes detachable in the cut-and-raised groove formed in the said side surface. At the same time, the convex piece formed on the side surface can be inserted into and removed from the cut groove on the side surface of the lid.
Therefore, when the convex portion protruding from the side surface of the lid is inserted into the cut and raised groove formed on the side surface, and the convex piece portion formed on the side surface is inserted into the groove on the side surface of the lid body, Due to the resistance and elasticity, the lid of the packaging box remains closed. In addition, when the convex portion protruding from the side surface of the lid is not inserted into the cut and raised groove formed on the side surface, the convex piece portion formed on the side surface is not inserted into the groove on the side surface of the lid body. When the packaging box lid remains open.

更に、４側面からなる箱本体の特定の側面から連続的に切曲形成され、前記４側面からなる箱本体の底面の対向側面までの距離に形成された底面の自由端側に突出形成された１個以上の係合凸部は、前記箱本体の底面を切曲形成した側面に対向する側面の下部に形成された前記底面の自由端側に突出形成された切欠部に収容される。それにより、前記箱本体の底は、長方形から平行四辺形に変化できなくなり、かつ、各側面から形成される底片と共に略２重底となり、機械的強度が高くなる。 Furthermore, it was continuously formed by bending from a specific side surface of the box body consisting of four side surfaces, and formed to project to the free end side of the bottom surface formed at a distance to the opposite side surface of the bottom surface of the box body consisting of the four side surfaces. The one or more engaging convex portions are accommodated in a notch portion that is formed at the lower end of the side surface that faces the side surface that is formed by bending the bottom surface of the box body and protrudes toward the free end of the bottom surface. Thereby, the bottom of the box body cannot be changed from a rectangle to a parallelogram, and becomes a substantially double bottom together with a bottom piece formed from each side surface, and the mechanical strength is increased.

次に、本発明の実施の形態について、図を用いて説明する。 Next, embodiments of the present invention will be described with reference to the drawings.

図１から図６において、短辺側の側面１，３、長辺側の側面２，４の４側面は、糊代面５が長辺側の側面４の裏面に接着剤で接着され、四角の枠体となり箱本体Ａが形成されている。蓋体１３を形成する側面は、側面４に限定されるものではなく、側面１，２，３のいずれでもよい。しかし、図１の展開図からわかるように、短辺側の側面１，３に形成すると、距離が長くなり、無駄な紙面の量が多くなる。したがって、長辺側の側面２，４に形成するのが望ましい。 In FIG. 1 to FIG. 6, the side surfaces 1 and 3 on the short side side and the side surfaces 2 and 4 on the long side side are bonded to the back surface of the side surface 4 on the long side with adhesive. A box body A is formed. The side surface forming the lid 13 is not limited to the side surface 4, and may be any one of the side surfaces 1, 2, and 3. However, as can be seen from the developed view of FIG. 1, when it is formed on the side surfaces 1 and 3 on the short side, the distance becomes long and the amount of wasted paper becomes large. Therefore, it is desirable to form on the side surfaces 2 and 4 on the long side.

蓋体１３の自由端側に折曲形成した蓋体側面１４は、箱本体Ａの蓋体１３を連続的に形成した側面４に対向する側面２と重なり合う部分である。したがって、その面積は広いことが望ましいが、その程度は、意匠性によって判断することができる。
蓋体側面１４には、その中央に蓋体側面１４から突出した略長方形状の凸部１４ａが形成されている。略長方形状の凸部１４ａに対向する蓋体側面１４の位置に、蓋体側面１４に凸部１４ａ側に凸の湾曲した切溝１４ｂが形成されている。
なお、開口片１１及び開口片１２は、箱本体Ａと蓋体１３との隙間をなくすものであり、公知の構造であり、任意の大きさに形成される。 The lid body side surface 14 bent at the free end side of the lid body 13 is a portion overlapping the side surface 2 facing the side surface 4 formed continuously with the lid body 13 of the box body A. Therefore, although it is desirable that the area is large, the degree can be judged by the design property.
A substantially rectangular convex portion 14 a that protrudes from the lid side surface 14 is formed at the center of the lid side surface 14. At the position of the lid body side surface 14 that faces the substantially rectangular convex portion 14a, a curved cut groove 14b that is convex toward the convex portion 14a side is formed on the lid body side surface 14.
The opening piece 11 and the opening piece 12 eliminate a gap between the box body A and the lid body 13 and have a known structure, and are formed in an arbitrary size.

短辺側の側面１及び側面３の下方には、各々底片２１及び底片２３が形成されている。各底片２１及び底片２３は、側面１及び側面３から内側に折り畳み自在となっており、更に、側面１及び側面３の下辺から４５度の折り畳みができるように、折り畳み線２１ａと折り畳み線２３ａが形成されている。この折り畳み線２１ａと折り畳み線２３ａは、箱本体Ａの内側に折り込まれる。
側面１と側面３の下辺から４５度の折り畳みができるように形成された折り畳み線２１ａと折り畳み線２３ａの範囲外は、糊代２１ｂと糊代２３ｂとなっている。 A bottom piece 21 and a bottom piece 23 are respectively formed below the side surface 1 and the side surface 3 on the short side. Each of the bottom piece 21 and the bottom piece 23 can be folded inward from the side surface 1 and the side surface 3, and further, a fold line 21 a and a fold line 23 a can be folded from the lower side of the side surface 1 and the side surface 3. Is formed. The fold line 21a and the fold line 23a are folded inside the box body A.
Out of the range of the fold line 21a and the fold line 23a formed so as to be able to fold 45 degrees from the lower sides of the side surface 1 and the side surface 3, there is a paste margin 21b and a paste margin 23b.

また、長辺側の側面４の下方には、箱本体Ａの内側の底部寸法に近似した底面２４が形成されている。即ち、底面２４は、長辺側の側面４と略同一であり、端辺側の側面１，３と略同一または１／２程度の長さまでに形成される。長辺側の側面２の下方には、箱本体Ａの内側の寸法に近似した底面２２が形成されている。即ち、底面２２は、長辺側の側面２と略同一であり、端辺側の側面１，３と略同一程度の長さに形成される。 In addition, a bottom surface 24 that approximates the bottom dimension inside the box body A is formed below the side surface 4 on the long side. That is, the bottom surface 24 is substantially the same as the side surface 4 on the long side, and is formed to have a length substantially the same as or about 1/2 of the side surfaces 1 and 3 on the end side. A bottom surface 22 approximate to the inner dimension of the box body A is formed below the side surface 2 on the long side. That is, the bottom surface 22 is substantially the same as the side surface 2 on the long side and is formed to have a length that is substantially the same as the side surfaces 1 and 3 on the end side.

そして、底面２２には、長辺側の側面２の反対側に２個の係合凸部２２ａ，２２ｂが形成されている。係合凸部２２ａ，２２ｂは、略長方形である。したがって、底面２２の短辺側の長さは、正確には、係合凸部２２ａ，２２ｂの幅が加えられるので、側面１，３の長さよりも若干長くなっている。 The bottom surface 22 is formed with two engaging convex portions 22a and 22b on the opposite side of the side surface 2 on the long side. The engaging convex portions 22a and 22b are substantially rectangular. Accordingly, the length of the short side of the bottom surface 22 is slightly longer than the length of the side surfaces 1 and 3 because the width of the engaging convex portions 22a and 22b is added.

底面２２の短辺側の両端部には、切欠き２２ｃ及び切欠き２２ｄにより形成された凸部２２ｅ，２２ｆを有している。切欠き２２ｃ，２２ｄ及び凸部２２ｅ，２２ｆは、位置決め及び装着をし易くするための構造となるものであり、必ずしも、本発明に、必要とするものではない。 At both ends on the short side of the bottom surface 22, there are convex portions 22e and 22f formed by a notch 22c and a notch 22d. The notches 22c and 22d and the convex portions 22e and 22f are structures for facilitating positioning and mounting, and are not necessarily required for the present invention.

側面１の下辺に形成された糊代２１ｂは、底面２２の短辺側の一方の裏面に接着され、折り畳み線２１ａと底面２２の短辺側の辺が略一致するように接着される。また、側面３の下辺に形成された糊代２３ｂは、底面２４の短辺側の一方の裏面に接着され、折り畳み線２３ａと底面２４の短辺側の辺が略一致するように接着される。これらの接合位置は、箱本体Ａの内側の対角線上の位置となる。また、接着状態では、折り畳み線２１ａ及び折り畳み線２３ａが折れていないとき、箱本体Ａは長方形となり、短辺側の側面１，３及び長辺側の側面２，４の４側面は、底片２１及び底片２３に直角となる。
この状態で、底面２２は底面２４よりも内側（上面側）に重なって位置することになる。 The glue margin 21b formed on the lower side of the side surface 1 is bonded to one back surface on the short side of the bottom surface 22, and is bonded so that the folding line 21a and the short side of the bottom surface 22 are substantially coincident with each other. Further, the glue margin 23b formed on the lower side of the side surface 3 is bonded to one back surface on the short side of the bottom surface 24, and is bonded so that the side of the fold line 23a and the short side of the bottom surface 24 substantially coincides with each other. . These joining positions are positions on diagonal lines inside the box body A. Further, in the bonded state, when the fold line 21a and the fold line 23a are not folded, the box body A is rectangular, and the side surfaces 1, 3 on the short side and the side surfaces 2, 4 on the long side are formed on the bottom piece 21. And a right angle to the bottom piece 23.
In this state, the bottom surface 22 is positioned so as to overlap the inner side (upper surface side) than the bottom surface 24.

長辺側の側面２には、上方向に突出した逆Ｕ字状の切り起し溝２ｂ及び切り起し溝２ｂによって突出した凸片部２ａが形成される。即ち、箱本体Ａの蓋体１３を連続的に形成した側面４に対向する側面２に形成した切り起し溝２ｂによって、蓋体側面１４から突出形成した凸部１４ａが挿脱自在に収容されると同時に、側面２の切り起し溝２ｂによって蓋体側面１４に形成した切溝１４ｂに挿脱自在な凸片部２ａとを有している。 On the side surface 2 on the long side, an inverted U-shaped cut-and-raised groove 2b protruding upward and a protruding piece portion 2a protruding by the cut-and-raised groove 2b are formed. That is, the protruding portion 14a that protrudes from the side surface 14 of the box body is detachably accommodated by the cut and raised groove 2b formed on the side surface 2 that faces the side surface 4 that continuously forms the lid body 13 of the box body A. At the same time, it has a protruding piece 2a that can be inserted into and removed from a cut groove 14b formed in the lid side face 14 by the cut and raised groove 2b of the side face 2.

４側面１，２，３，４からなる箱本体Ａの側面４の下部には、切欠部４ａ，４ｂが形成されている。切欠部４ａ，４ｂは、底部２２の自由端側に突出形成された１個以上の係合凸部２２ａ，２２ｂを挿脱自在になっている。切欠部４ａ，４ｂに係合凸部２２ａ，２２ｂが挿入状態では、箱本体Ａの底部が底面２２で拘束され、長方形から平行四辺形に変更できなくなっている。即ち、切欠部４ａ，４ｂに係合凸部２２ａ，２２ｂが挿入状態では、係合凸部２２ａ，２２ｂが切欠部４ａ，４ｂの幅以上の移動が拘束され、かつ、箱本体Ａの底部では、凸部２２ｅ及び凸部２２ｆによって箱本体Ａの底部が、長方形から平行四辺形に変更できなくなっている。 Notches 4a and 4b are formed at the lower part of the side surface 4 of the box body A composed of the four side surfaces 1, 2, 3 and 4. The notches 4a and 4b are detachable from one or more engaging projections 22a and 22b that are formed to protrude toward the free end of the bottom 22. When the engagement convex portions 22a and 22b are inserted into the notches 4a and 4b, the bottom portion of the box body A is restrained by the bottom surface 22 and cannot be changed from a rectangle to a parallelogram. That is, when the engaging protrusions 22a and 22b are inserted into the notches 4a and 4b, the engaging protrusions 22a and 22b are restrained from moving beyond the width of the notches 4a and 4b, and at the bottom of the box body A, The bottom of the box body A cannot be changed from a rectangular shape to a parallelogram by the convex portions 22e and the convex portions 22f.

ここで、包装用箱において、底面２２は底面２４よりも内側（上面側）とし、かつ、底面２４も側面４の内側に重なるように、箱本体Ａの長方形を崩すと、平行四辺形状となり、図５及び図６に示すように、折り畳むことができる。 Here, in the packaging box, if the rectangle of the box body A is broken so that the bottom surface 22 is on the inner side (upper surface side) than the bottom surface 24 and the bottom surface 24 also overlaps the inner side of the side surface 4, a parallelogram shape is obtained. As shown in FIGS. 5 and 6, it can be folded.

（実施の形態２）
図７は本発明の実施の形態２の包装用箱の展開図である。なお、本実施の形態において、実施の形態１と同一記号または同一符号は、上記実施の形態１と同一または相当する構成部分を示すものであり、特に、本実施の形態では、上記実施の形態１との相違点について重点をおいて説明し、説明されていない事項は、基本的に実施の形態１と同様の趣旨の構成部分である。 (Embodiment 2)
FIG. 7 is a development view of the packaging box according to the second embodiment of the present invention. In the present embodiment, the same symbols or the same reference numerals as those in the first embodiment indicate the same or corresponding components as those in the first embodiment. In particular, in the present embodiment, the above embodiment is described. Differences from 1 will be described with emphasis, and items that are not described are basically components having the same meaning as in the first embodiment.

長辺側の側面２の下方には、箱本体Ａの内側の寸法に近似した底面２２が形成されて折、底面２２は、長辺側の側面２と略同一であり、端辺側の側面１，３と略同一程度の長さに形成される。詳しくは、底面２２には、長辺側の側面２の反対側に２個の係合凸部２２ａａ，２２ｂｂが形成されている。係合凸部２２ａａ，２２ｂｂは、略Ｌ字形である。したがって、底面２２の短辺側の長さは、正確には、係合凸部２２ａａ，２２ｂｂの幅が加えられるので、側面１，３の長さよりも若干長くなっている。 A bottom surface 22 approximate to the inner dimension of the box body A is formed below the side surface 2 on the long side and folded. The bottom surface 22 is substantially the same as the side surface 2 on the long side, and the side surface on the end side. 1 and 3, approximately the same length. Specifically, two engagement convex portions 22aa and 22bb are formed on the bottom surface 22 on the side opposite to the side surface 2 on the long side. The engaging convex portions 22aa and 22bb are substantially L-shaped. Accordingly, the length of the short side of the bottom surface 22 is slightly longer than the length of the side surfaces 1 and 3 because the width of the engaging projections 22aa and 22bb is added.

４側面１，２，３，４からなる箱本体Ａの側面４の下部には、切欠部４ａ，４ｂが形成されている。切欠部４ａ，４ｂは、底部２２の自由端側に突出形成された１個以上の係合凸部２２ａａ，２２ｂｂを挿脱自在になっている。切欠部４ａ，４ｂに係合凸部２２ａａ，２２ｂｂが挿入状態では、箱本体Ａの底部が底面２２で拘束され、長方形から平行四辺形に変更できなくなっている。即ち、切欠部４ａ，４ｂに係合凸部２２ａａ，２２ｂｂが挿入状態では、係合凸部２２ａａ，２２ｂｂが切欠部４ａ，４ｂの幅以上の移動が拘束され、かつ、箱本体Ａの底部では、凸部２２ｅ及び凸部２２ｆによって箱本体Ａの底部が、長方形から平行四辺形に変更できなくなっている。
そして、本実施の形態では、係合凸部２２ａａ，２２ｂｂの略Ｌ字形が、切欠部４ａ，４ｂに挿入されると、側面４のいずれかの位置に係合し、容易に離脱できなくなり、安定した箱状態を維持できる。 Notches 4a and 4b are formed at the lower part of the side surface 4 of the box body A composed of the four side surfaces 1, 2, 3 and 4.

At the same time, the convex piece 2 a formed on the side surface 2 can be inserted into and removed from the groove 14 b on the side surface 14 of the lid. Therefore, the convex part 14a which protrudes from the cover body side face 14 is inserted into the cut and raised groove 2b formed on the side face 2, and the convex piece part 2a formed on the side face 2 is inserted into the cut groove 14b on the cover body side face 14. Due to the contact resistance, the lid 14 of the packaging box is kept closed. In addition, when the convex portion 14 a protruding from the lid side surface 14 is not inserted into the cut and raised groove 2 b formed on the side surface 2, the convex piece portion 2 a formed on the side surface 2 becomes the cut groove 14 b on the lid side surface 14. When not inserted, the lid 13 of the packaging box remains open. Therefore, the packaging box can be folded and can maintain the open state or the closed state of the lid 13 when it is in the box state.
