The paper layer may contain a liquid-resistant agent.

第1例では、箱本体1Aを組み立てるシートとして、箱本体1Aの内面となる一面に耐液体性の塗料がコーティングされた紙製の段ボールシートが使用されている。また、蓋体1Bを組み立てるシートとして、紙製の段ボールシートが使用されている。なお、蓋体1Bの内面となる一面に耐液体性の塗料がコーティングされていてもよく、利用する用途に応じて箱本体1A、および/または蓋体1Bの外面となる一面に耐液体性の塗料がコーティングされていてもよい。 In the first example, as the sheet for assembling the box body 1A, a corrugated cardboard sheet made of paper coated with a liquid-resistant paint is used on the inner surface of the box body 1A. A cardboard sheet made of paper is used as a sheet for assembling the lid body 1B. In addition, the inner surface of the lid 1B may be coated with a liquid-resistant paint. It may be coated with paint.

このような段ボールシートで形成される箱本体1Aおよび蓋体1Bは、ともに図2の展開図で示すように、箱本体1Aの場合は底板部に、そして蓋体1Bの場合は天板部となる矩形状の平板部2の相対向する二辺にそれぞれ第1折線3を介して第1側壁部4が設けられ、平板部2の他の相対向する二辺にそれぞれ第2折線5を介して第2側壁部6が設けられている。 The box main body 1A and the lid 1B formed of such corrugated cardboard sheets are, as shown in the development view of FIG. A first side wall portion 4 is provided on two opposite sides of a rectangular flat plate portion 2 with a first folding line 3 interposed therebetween, and a second side wall portion 4 is provided on the other two opposite sides of the flat plate portion 2 with a second folding line 5 interposed therebetween. A second side wall portion 6 is provided at the end.

隣り合う第1側壁部4と第2側壁部6の間には、両側端縁にそれぞれ第3折線7、第4折線8を介して連接し、両側端縁を2辺とする四角形に形成され、第3折線7、第4折線8の間の対角線を第5折線9として内方に二つ折りされ三角形となって第2側壁部6の内面側に折り込まれる折込部10が設けられている。
折込部10を形づくる四角形は、本例では正方形となっているが、第4折線8に対し、第3折線7の長さを第4折線8より若干短くした四角形であってもよい。
Between the first side wall portion 4 and the second side wall portion 6 which are adjacent to each other, there is formed a quadrangle having both side edges as two sides, which is connected to both side edges via a third folding line 7 and a fourth folding line 8, respectively. , and a diagonal line between the third folding line 7 and the fourth folding line 8 is a fifth folding line 9, and a folded portion 10 is provided to be folded inwardly into a triangular shape on the inner surface side of the second side wall portion 6.例文帳に追加

When the cutout depth of the concave portion 12 is two to three times the sheet thickness, when the projecting pieces 11a and 11b are fitted into the fitting openings of the locking pieces to be described later, the projecting pieces 11a and 11b are cut. protrudes from the fitting opening of the locking piece by at least a width equal to or greater than the thickness of the sheet, so that a reliable locking state can be obtained between the projecting pieces 11a and 11b and the locking piece. Also, the opening of the assembled box main body 1A can be tightly covered with an inner lid, which will be described later. In this example, the cut depth of the recess 12 is three times the thickness of the sheet.

また、第2側壁部6の開放辺に第6折線14を介して連接する係止片部15が設けられ、係止片部15と第2側壁部6の間に折込部10に設けられた突片部11a,11bが嵌合する嵌合口16a,16bが形成されており、係止片部15を第6折線14から谷折りすることにより、嵌合口16a,16bに第2側壁部2の内面側に折り込まれた折込部10に設けられた突片部11a,11bが嵌合するようになっている。 In addition, a locking piece 15 is provided on the open side of the second side wall 6 and connected to the open side of the second side wall 6 via a sixth folding line 14 . Fitting openings 16a and 16b into which the projecting pieces 11a and 11b are fitted are formed. Projecting pieces 11a and 11b provided on the folded portion 10 folded inward are fitted.

第2側壁部6の開放辺に設けられている係止片部15にあっては、係止片部15の中央に第2側壁部6の開放辺に沿って、重なり合う2つの突部13a,13aからなる一方の突片部11aが嵌合する穴状の嵌合口16aが中央に形成され、係止片部15の両側に第2側壁部6の開放辺に沿って、重なり合う2つの突部13b,13bからなる他方の突片部11bが嵌合する溝状の嵌合口16bが形成されている。 In the locking piece portion 15 provided on the open side of the second side wall portion 6, two overlapping protrusions 13a, A hole-shaped fitting opening 16a into which one protruding piece portion 11a composed of 13a is fitted is formed in the center, and two overlapping protruding portions are formed on both sides of the locking piece portion 15 along the open side of the second side wall portion 6. A groove-like fitting opening 16b is formed in which the other projecting piece portion 11b composed of 13b, 13b is fitted.

そして、穴状の嵌合口16aと溝状の嵌合口16bとの間が第2側壁部6に連接している連接部17となり、連接部17は折込部10の2つの開放辺に形成された凹部12に嵌合可能な幅となっており、さらに第2側壁部6には、凹部12の深さを超えない範囲で連接部17の一部を形成する切り込み18が設けられ、切り込み18の先端を結ぶ線が第6折線14となっている。また、係止片部15には連接部17を仕切る第7折線19が設けられている。 A connection portion 17 is formed between the hole-shaped fitting opening 16a and the groove-shaped fitting opening 16b and is connected to the second side wall portion 6. The connection portion 17 is formed on the two open sides of the folded portion 10. The second side wall portion 6 is provided with a notch 18 that forms a part of the connecting portion 17 within a range not exceeding the depth of the recess 12 . A line connecting the ends is a sixth folding line 14 . Further, the locking piece portion 15 is provided with a seventh folding line 19 that partitions the connecting portion 17 .

このような展開構造を有する箱本体1Aおよび蓋体1Bは、次のようにして組み立てられる。
先ず、平板部2の相対向する二辺に設けられている第1側壁部4を第1折線3から谷折りして立ち上げるとともに、平板部2の他の相対向する二辺に設けられている第2側壁部6を第2折線5から谷折りして立ち上げ、この第1側壁部4と第2側壁部6の立ち上げと同期して、隣り合う第1側壁部4と第2側壁部6の間に設けられている四角形の折込部10を、対角線となる第5折線9を山折りし、第3折線7、第4折線8を谷折りして内方に二つ折りして三角形とし、第2側壁部6の内面側に折り込む。

First, the first side wall portions 4 provided on the two opposite sides of the flat plate portion 2 are valley-folded from the first folding line 3 and raised, and the other two opposite sides of the flat plate portion 2 are provided. The second side wall portion 6 is valley-folded from the second folding line 5 and raised. A square folded portion 10 provided between the portions 6 is folded in half by mountain-folding the fifth folding line 9, which is a diagonal line, and valley-folding the third folding line 7 and the fourth folding line 8 to form a triangle. , and folded into the inner surface side of the second side wall portion 6 .

折込部10を内方に二つ折りして三角形としたとき、折込部10の2つの開放辺に形成された凹部12同士と、突部13a,13b同士が重なり、重なった突部13a,13bが折込部10の開放辺に設けられる突片部11a,11bとなる(図3参照。)。 When the folded portion 10 is folded inward to form a triangle, the concave portions 12 formed on the two open sides of the folded portion 10 and the protrusions 13a and 13b overlap each other, and the overlapping protrusions 13a and 13b overlap each other. These are projecting pieces 11a and 11b provided on the open side of the folded portion 10 (see FIG. 3).

次に、第2側壁部6の開放辺に設けられている係止片部15を第6折線14から谷折りして内方に倒し、係止片部15と第2側壁部6の間に形成されている嵌合口16a,16bに、折込部10に設けられた突片部11a,11bを嵌合させる。 Next, the locking piece portion 15 provided on the open side of the second side wall portion 6 is valley-folded from the sixth fold line 14 and folded inward, so that the locking piece portion 15 and the second side wall portion 6 are separated from each other. The protrusions 11a and 11b provided in the folded portion 10 are fitted into the formed fitting openings 16a and 16b.

第1例では、係止片部15にあっては、係止片部15の中央に第2側壁部6の開放辺に沿って、重なり合う2つの突部13a,13aからなる一方の突片部11aが嵌合する穴状の嵌合口16aが係止片部15と第2側壁部6の間における中央に形成され、係止片部15の両側に第2側壁部6の開放辺に沿って、重なり合う2つの突部13b,13bからなる他方の突片部11bが嵌合する溝状の嵌合口16bが形成されており、穴状の嵌合口16aと溝状の嵌合口16bとの間が第2側壁部6に連接している連接部17となり、連接部17は折込部10の2つの開放辺に形成された凹部12に嵌合可能な幅にとなっており、さらに第2側壁部6には、凹部12の深さを超えない範囲で連接部17の一部を形成する切り込み18が設けられ、切り込み18の先端を結ぶ線が第6折線14となっており、係止片部15を第6折線14から谷折りして内方に倒し、連接部17を凹部12に嵌合することにより、折込部10に設けられた突片部11a,11bを係止片部15と第2側壁部6の間に形成されている嵌合口16a,16bに嵌合させる(図3参照。)。
この時、折込部10を形づくる四角形が、第4折線8に対し、第3折線7の長さを第4折線8より若干短くした四角形であると、後述する内蓋20を取り付けた状態で蓋体1Bを被せた際、より安定した形で箱本体1Aに蓋をすることができると共に、内容物の入った蓋付箱1を複数段積み重ねた状態であっても崩れにくくなる。
In the first example, in the locking piece 15, one of the projections 13a, 13a is formed along the open side of the second side wall 6 at the center of the locking piece 15 and consists of two overlapping projections 13a, 13a. A hole-shaped fitting opening 16a into which 11a is fitted is formed in the center between the locking piece 15 and the second side wall 6, and is formed on both sides of the locking piece 15 along the open side of the second side wall 6 A groove-like fitting opening 16b is formed in which the other projecting piece portion 11b consisting of two overlapping projections 13b and 13b is fitted, and the gap between the hole-like fitting opening 16a and the groove-like fitting opening 16b is formed. It becomes a connecting portion 17 connected to the second side wall portion 6, and the connecting portion 17 has a width that can be fitted into the concave portions 12 formed on the two open sides of the folded portion 10, and furthermore, the second side wall portion. 6 is provided with a notch 18 that forms a part of the connecting portion 17 within a range not exceeding the depth of the recess 12, and a line connecting the tips of the notch 18 is a sixth folding line 14, and the locking piece portion 15 is folded inward from the sixth folding line 14, and the connecting portion 17 is fitted into the concave portion 12, so that the projecting pieces 11a and 11b provided in the folded portion 10 are connected It is fitted into the fitting openings 16a and 16b formed between the two side wall portions 6 (see FIG. 3).
At this time, if the quadrangle forming the folding portion 10 is a quadrangle with the length of the third folding line 7 being slightly shorter than the length of the fourth folding line 8, the lid can be opened with the inner lid 20 (to be described later) attached. When covered with the body 1B, the box main body 1A can be covered in a more stable manner, and even when the boxes 1 with lids containing the contents are stacked in a plurality of stages, they do not collapse easily.

このようにして箱本体1Aおよび蓋体1Bの組み立てが完了するが、特に、蓋体1Bの場合は、第6折線14から谷折りして内方に倒した係止片部15を、さらに第7折線19から谷折りして第2側壁部6の内面側に折り込まれている折込部10に重ねるようにして蓋体1Bの組み立てが完了する(図1参照。)。 In this way, the assembly of the box main body 1A and the lid 1B is completed. Especially in the case of the lid 1B, the engaging piece 15 folded inward by valley folding from the sixth folding line 14 is further The assembly of the lid body 1B is completed by making a valley fold from the 7-fold line 19 and overlapping the folded portion 10 folded on the inner surface side of the second side wall portion 6 (see FIG. 1).

また、箱本体1Aの場合は、第6折線14から谷折りして内方に倒した係止片部15を、さらに第7折線19から谷折りする必要は無いが(図1参照。)、蓋体1Bのように、係止片部15を第7折線19から谷折りして第2側壁部6の内面側に折り込まれている折込部10に重ねるようにしてもよい。 Further, in the case of the box body 1A, it is not necessary to further fold the locking piece 15, which has been folded inward from the sixth fold line 14, from the seventh fold line 19 (see FIG. 1). As in the case of the lid 1B, the locking piece 15 may be valley-folded from the seventh folding line 19 and overlapped with the folded portion 10 folded into the inner surface side of the second side wall portion 6 .

このように構成された第1例の箱本体1Aおよび蓋体1Bは、隣り合う第1側壁部4と第2側壁部6の間に設けられている折込部10を内方に二つ折りしながら、平板部2から第1側壁部4と第2側壁部6を立ち上げ、二つ折りした折込部を第2側壁部6の内面側に折り込んで第2側壁部6の内面に重ね、この状態から、第2側壁部6の開放辺に設けられている係止片部15を第6折線14から谷折りして、係止片部15と第2側壁部6の間に形成されてる嵌合口16a,16bに第2側壁部6の内面側に折り込まれた折込部10の開放辺に設けられた突片部11a,11bを嵌合させるといった簡単な作業で容易に組み立てることができる。 The box main body 1A and the lid 1B of the first example configured in this way are folded inwardly in two at the folded portion 10 provided between the adjacent first side wall portion 4 and the second side wall portion 6. , the first side wall portion 4 and the second side wall portion 6 are erected from the flat plate portion 2, and the folded portions are folded in half to the inner surface side of the second side wall portion 6 and overlapped on the inner surface of the second side wall portion 6, and from this state, A fitting opening 16a is formed between the locking piece 15 and the second side wall 6 by valley-folding the locking piece 15 provided on the open side of the second side wall 6 from the sixth fold line 14. , 16b can be easily assembled by a simple operation such as fitting the projecting pieces 11a and 11b provided on the open side of the folded portion 10 folded on the inner surface side of the second side wall portion 6 to each other.

また、第1例では、折込部10の2つの開放辺に設けられている突片部11a,11bは、折込部10の2つの開放辺の中央部位が、シート厚を超える深さに切り取られて凹部12が形成され、凹部12の両側の突部13a,13bを突片部11a,11bとしており、折込部10の2つの開放辺に形成された凹部12同士が、そして突部13a,13b同士が折込部10を第5折線9から二つ折りしたとき重なるように形成されている。 In the first example, the projecting pieces 11a and 11b provided on the two open sides of the folded portion 10 are cut to a depth exceeding the thickness of the sheet at the central portions of the two open sides of the folded portion 10. The recessed portion 12 is formed on both sides of the recessed portion 12, and the projecting portions 11a and 11b are formed on both sides of the recessed portion 12. They are formed so that they overlap each other when the folded portion 10 is folded in two along the fifth fold line 9 .

そして、係止片部15にあっては、係止片部15の中央に第2側壁部6の開放辺に沿って、重なり合う2つの突部13a,13aからなる一方の突片部11aが嵌合する穴状の嵌合口16aが中央に形成され、係止片部15の両側に第2側壁部6の開放辺に沿って、重なり合う2つの突部13b,13bからなる他方の突片部11bが嵌合する溝状の嵌合口16bが形成されており、穴状の嵌合口16aと溝状の嵌合口16bとの間が第2側壁部6に連接している連接部17となり、連接部17は折込部10の2つの開放辺に形成された凹部12に嵌合可能な幅にとなっており、さらに第2側壁部6には、凹部12の深さを超えない範囲で連接部17の一部を形成する切り込み18が設けられ、切り込み18の先端を結ぶ線が第6折線14となっているので、第2側壁部6の開放辺に設けられている係止片部15を第6折線14から谷折りして内方に倒し、連接部17を凹部12に嵌合させることにより、折込部10に設けられた突片部11a,11bが係止片部15と第2側壁部6の間に形成されている嵌合口16a,16bに嵌合し、嵌合口16a,16bに嵌合した突片部11a,11bは、その先端が係止片部15の嵌合口16a,16bから突出した状態となるので、突片部11a,11bと係止片部15との間に確実な係止状態が得られ、第2側壁部6と、第2側壁部6の内面側に折り込まれた折込部10を確実に固定することができ、堅牢な箱本体1Aおよび蓋体1Bを得ることができる。 In the locking piece portion 15, one projecting piece portion 11a composed of two overlapping projections 13a, 13a is fitted in the center of the locking piece portion 15 along the open side of the second side wall portion 6. A matching hole-shaped fitting opening 16a is formed in the center, and the other projecting piece portion 11b consists of two overlapping projecting portions 13b, 13b along the open side of the second side wall portion 6 on both sides of the locking piece portion 15. A groove-shaped fitting opening 16b into which is fitted is formed. 17 has a width that can be fitted into the recessed portions 12 formed on the two open sides of the folded portion 10, and the second side wall portion 6 has connecting portions 17 within a range not exceeding the depth of the recessed portions 12. and a line connecting the tips of the cuts 18 is the sixth folding line 14, so that the locking piece portion 15 provided on the open side of the second side wall portion 6 can be moved to the second side wall portion 6. By folding the connecting portion 17 into the concave portion 12 by making a valley fold along the 6-fold line 14 and fitting the connecting portion 17 into the concave portion 12, the projecting portions 11a and 11b provided in the folded portion 10 are connected to the locking portion 15 and the second side wall portion. The protruding pieces 11a and 11b fitted into the fitting openings 16a and 16b formed between the fitting openings 16a and 16b have their tips extending from the fitting openings 16a and 16b of the locking piece portion 15. Since it is in a protruding state, a reliable locking state is obtained between the projecting pieces 11a and 11b and the locking piece 15, and the second side wall portion 6 and the inner surface side of the second side wall portion 6 are folded. In addition, the folded portion 10 can be securely fixed, and a strong box body 1A and lid body 1B can be obtained.

特に、第1例では、凹部12の切り取り深さはシート厚の3倍の深さとなっているので、嵌合口16a,16bに嵌合した突片部11a,11bは、その先端が係止片部15の嵌合口から少なくともシート厚以上の幅で突出するので、突片部11a,11bと係止片部15との間に一層確実な係止状態が得られ、一層堅牢な箱本体1Aおよび蓋体1Bを得ることができる。 In particular, in the first example, since the cut depth of the recess 12 is three times the sheet thickness, the projecting pieces 11a and 11b fitted in the fitting openings 16a and 16b have locking pieces at their tips. Since it protrudes from the fitting opening of the portion 15 with a width of at least the thickness of the sheet, a more reliable locking state can be obtained between the projecting pieces 11a and 11b and the locking piece portion 15, resulting in a more robust box body 1A and A lid 1B can be obtained.

また、組み立てられた箱本体1Aおよび蓋体1Bの第1側壁部4と第2側壁部6の外面には障害となるような出っ張り部を生じさせるようなことは無いので、取扱に便利な蓋付箱1を得ることができる。 In addition, since the outer surfaces of the first side wall portion 4 and the second side wall portion 6 of the assembled box main body 1A and the lid body 1B do not have protrusions which may become obstacles, the lid is convenient to handle. Attached box 1 can be obtained.

さらに、蓋体1Bにあっては、箱本体1Aに被せることが可能なように、内寸が箱本体1Aの外寸以上とする以外は、箱本体1Aと同一形状であるので、自動製函の際設備を簡素化することが可能となる。 Further, the lid body 1B has the same shape as the box body 1A except that the inner dimension is equal to or larger than the outer dimension of the box body 1A so that it can be covered with the box body 1A. It is possible to simplify the equipment in this case.

また、第1例の箱本体1Aは、着脱可能に取り付けられる内蓋20を備えていてもよい。内蓋20は、箱本体1Aの開口部の内側に納まる矩形状の板状体からなり、内蓋20の第2側壁部側の辺には、係止片部15に形成された穴状の嵌合口16aと溝状の嵌合口16bに嵌合し、係止片部15から突している折込部10の開放辺に設けられた突片部11aと突片部11bの間に嵌合する嵌合片21が形成されている(図4参照。)。板状体は箱本体1Aと同じシート状の材料が使用される。 Further, the box main body 1A of the first example may be provided with an inner lid 20 that is detachably attached.
