【発明の属する技術分野】
本発明は身と蓋が1枚の紙からなる2つのヒンジを持つワンピース箱(以降、「2ヒンジワンピース箱」と呼ぶ)における、背サイド壁(背壁の両サイド)のヒンジ折り込み構造に関する。
【0002】
【従来の技術】
従来から、身と蓋が1枚の紙からなる2ヒンジワンピース箱がある(例えば、特許文献1、非特許文献1参照)。図1に示すような身箱の中央部の両サイド壁を切り取り、両サイドが切り取られた中央部の身箱の底部分を背壁とし、背壁を中心に折り返すと、図2に示すような、2ヒンジの身、蓋ワンピース箱となる。図3は完全に蓋が閉まった状態を示す。

【0004】
【発明が解決しようとする課題】
上に述べた従来の2ヒンジワンピース箱では、蓋を開けたとき背の両サイドに壁がなく、身箱の箱としての機能が不完全である(小さな物の容器には不向き)。又蓋を閉めた状態でも蓋両サイド壁端は固定されておらず外観上も容器としての密閉性も悪い。
【0005】
本発明は従来の2ヒンジワンピース箱のヒンジ部両サイドの折り構造が有していた問題点を解決しようとするものであり、2ヒンジワンピース箱に於いて背両サイド壁を切り取らずに、折り込んだ背部サイド壁が背壁にぴったりと折り畳まれ、更に蓋閉め時、身箱は確実に蓋の内側に入っていくような、2ヒンジワンピース箱の背サイド壁のヒンジ折り込み構造を実現する事を目的とするものである。
【0006】
【課題を解決するための手段】
本発明は上記目的を達成するため、身、蓋が1枚の紙からなる2ヒンジワンピース箱において、身サイド壁、蓋サイド壁及び背壁に三方を囲まれる背サイド壁において、直角2等辺三角形△dbeで、折れ筋である辺beは直角2等辺三角形△abcの底辺abの二分の一以下、使用する紙厚味の2倍から10倍の長さ短い事を特徴とする背壁ヒンジ折り構造としたものである。
【0007】
また、第2の解決手段は、上記手段のなかで、カット辺af上に端点を有し、点cとを結ぶ折れ筋を1ないし2本有する事を特徴とする背壁ヒンジ折り構造としたものである。
【0008】
上記第1の課題解決手段による作用は次の通りである。本特許の背壁ヒンジ構造図を示す図5において、8、11、13で構成される蓋箱、10、12、14で構成される身箱を背壁9の2本のヒンジ線に沿って折り畳んでいくと、折れ筋fc及びbeが折れていくことで、直角2等辺三角形△bfcは背壁9側に倒れていく。同時に身サイド壁12の上端a点が蓋サイド壁11端の内側に入って行き、蓋は完全に身箱を覆うように閉まり、三角形△bfcは箱内で背壁9に完全密着する。
【0009】
また、第2の課題解決手段による作用は、上記第1の課題解決手段においても尚、蓋を閉める時、蓋が身に対してよじれた状態で閉められようとすると、身サイド壁12上端a点が蓋サイド壁11端の内側に入っていかなくなる場合がある。第2の課題解決手段は、この場合でも確実に蓋は身を覆うように閉まる役目をすることができる。
【0010】
【発明の実施の形態1】
以下、本発明の実施の形態を図4〜図8に基づいて説明する。
【0011】
図4は本発明により作られる2ヒンジワンピース箱の展開図である。点線は筋押しで、実線はカットを意味し、1枚の厚紙(0.3mm、300g/m2)からできている。
【0012】
折り筋bcとacの長さは等しく三角形△acbは直角2等辺三角形である。この中に、垂線fcとなる折り筋fcを設ける。折り筋acは身壁12の端部につながっている。三角形△dbeはカット辺deと折り筋beの長さが等しい直角2等辺三角形であり、折り筋dbは蓋壁11の端部につながっている。
【0013】
折り筋beは直角2等辺三角形△abcの底辺ab上にあり、その長さは辺abの2分の一以下とする。即ち折り筋beは折り筋fcより短く、その差となるカット辺feは使用する紙厚みの最低2倍以上、10倍までになるようにする。
【0014】
尚、身箱サイズより、蓋箱サイズを紙厚み分だけ大きくしておくと、身、蓋の勘合がきれいになる。又、折れ筋be、fcは箱の外側面から筋押しした方が望ましい。
【0015】
図5は箱状に組みあがった状態を示す。12と14、11と13の各コーナー止め15はこの実施例ではテープで行っているが、このコーナー止め方法は本発明とは何ら関係していないので、今後説明しない。
【0016】
【発明の実施の形態2】
実施の形態1に於いて、点cよりカット線の一部afの中点に向けて折れ筋cgをいれた。
【0017】
以下、上記構成の実施の形態1の動作を説明する。図5,図6、図7、図8は8、11、13からなる蓋が閉まるまでの背壁ヒンジ折り構造の変化を示すものである。図5の箱が出来上がったら、二つの三角形△fcbが箱内側に向かうよう両側から押しながら蓋を閉めていくと、身サイド壁12端のa点が自然に蓋サイド壁12の内側に入り込んで、蓋は身を完全に覆うように閉まる。この作業を一度だけ行えばあとは、通常に蓋を閉めれば、必ず身を蓋が覆うように閉まる。辺feが紙厚の2倍以上あれば蓋が身の外側に覆うようになり、辺feが長いほどこの作用は確実になる。ただし、箱の蓋を開けたときの背サイド壁が低くなり容器としての機能は低くなるため、折り筋の入れ方、紙種類などで辺feの長さは出来るだけ短くて済むようにする。
【0018】
蓋が完全閉まると、三角形△fcbは背壁9にぴったりと押しつけられたように両コーナーに収まる。
【0019】
実施の形態2では蓋閉めじ、身、蓋がよじれた状態で閉められても、蓋は確実に身を覆うように閉まる。
【0020】
【発明の効果】
上述したように本発明の身、蓋が1枚の紙からなる2ヒンジワンピース箱における、背サイド壁のヒンジ折り込み構造により、背壁両サイドから小さな内容物がこぼれる事なく、蓋閉め時の身、蓋の嵌合は確実に行われ、更に箱内ではヒンジ折り込み部分がコーナーにぴったり収まり、箱内の有効体積を最大にする事が出来る。

BACKGROUND OF THE INVENTION
The present invention relates to a hinge folding structure of a back side wall (both sides of a back wall) in a one-piece box (hereinafter referred to as a “two-hinge one-piece box”) having two hinges whose body and lid are made of a single sheet of paper.
[0002]
[Prior art]
Conventionally, there is a two-hinge one-piece box whose body and lid are made of a single sheet of paper (for example, see Patent Document 1 and Non-Patent Document 1). When both side walls at the center of the body box as shown in FIG. 1 are cut out, the bottom part of the body box at the center part where both sides are cut out is used as the back wall, and folded back around the back wall, as shown in FIG. It becomes a body of 2 hinges and a lid one-piece box. FIG. 3 shows a state in which the lid is completely closed.

[Non-patent literature]
"Stokes News", Kubo Manufacturing Co., Ltd., October 1995, 1 page, one-piece box [0004]
[Problems to be solved by the invention]
In the conventional two-hinge one-piece box described above, there are no walls on both sides of the back when the lid is opened, and the function as a box of the body box is incomplete (not suitable for small containers). Even when the lid is closed, the side wall ends of the lid are not fixed, and the airtightness as a container is poor.
[0005]
The present invention is intended to solve the problem of the conventional folding structure of both sides of the hinge part of the two-hinge one-piece box, and the two-hinge one-piece box is folded without cutting back and side walls. To realize the hinge folding structure of the back side wall of the two-hinged one-piece box so that the back side wall is folded tightly against the back wall, and when the lid is closed further, the body box surely enters the inside of the lid It is the purpose.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a two-hinged one-piece box whose body and lid are made of a single sheet of paper, and a right-angled isosceles triangle on the body side wall, the lid side wall and the back side wall surrounded by the back wall. Δbe, the side be, which is a crease, is less than half of the right side isosceles triangle Δabc, and is shorter by 2 to 10 times the length of the paper thickness to be used. It is structured.
[0007]
Further, the second solution means is a back wall hinge fold structure characterized in that, among the above means, it has an end point on the cut side af and has one or two folding lines connecting the point c. Is.
[0008]
The operation of the first problem solving means is as follows. In FIG. 5 showing the back wall hinge structure diagram of this patent, the lid box composed of 8, 11 and 13 is connected to the body box composed of 10, 12, and 14 along the two hinge lines of the back wall 9. As it is folded, the bend lines fc and be are folded, so that the right-angled isosceles triangle Δbfc falls to the back wall 9 side. At the same time, the upper end point a of the body side wall 12 enters the inside of the end of the lid side wall 11, the lid is completely closed so as to cover the body box, and the triangle Δbfc is in close contact with the back wall 9 within the box.
[0009]
Further, the action of the second problem-solving means is that the first problem-solving means also has the upper end a of the body side wall 12 when the lid is closed with the lid kinked against the body. In some cases, the point may not enter the end of the lid side wall 11. Even in this case, the second problem solving means can reliably serve to close the lid so as to cover the body.
[0010]
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[0011]
FIG. 4 is an exploded view of a two-hinge one-piece box made in accordance with the present invention. The dotted line is a line push, and the solid line means a cut, and is made of a single cardboard (0.3 mm, 300 g / m 2).
[0012]
The lengths of the folding lines bc and ac are equal, and the triangle Δacb is a right-angled isosceles triangle. In this, a folding line fc to be a perpendicular line fc is provided. The folding line ac is connected to the end of the body wall 12. The triangle Δdbe is a right-angled isosceles triangle having the same length of the cut side de and the folding line be, and the folding line db is connected to the end of the lid wall 11.
[0013]
The folding line be is on the base ab of the right-angled isosceles triangle Δabc, and the length thereof is not more than half of the side ab. In other words, the crease be is shorter than the crease fc, and the cut side fe that is the difference between the crease be is at least two times to 10 times the thickness of the paper to be used.
[0014]
If the lid box size is made larger by the paper thickness than the body box size, the fit between the body and the lid becomes clean. Further, it is desirable that the folding lines be and fc are pushed from the outer surface of the box.
[0015]
FIG. 5 shows a state assembled in a box shape. Although the corner stops 15 of 12, 14, and 11 and 13 are made of tape in this embodiment, this corner stop method is not related to the present invention and will not be described.
[0016]
Second Embodiment of the Invention
In the first embodiment, the bending line cg is inserted from the point c toward the midpoint of a part af of the cut line.
[0017]
Hereinafter, the operation of the first embodiment having the above configuration will be described. 5, FIG. 6, FIG. 7 and FIG. 8 show the change of the back wall hinge folding structure until the lid composed of 8, 11 and 13 is closed. When the box of FIG. 5 is completed, when the lid is closed while pushing from both sides so that the two triangles Δfcb are directed to the inside of the box, the point “a” at the end of the body side wall 12 naturally enters the inside of the lid side wall 12. The lid is closed to cover the body completely. If this operation is performed only once, the lid will normally be closed if the lid is normally closed. If the side fe is twice or more the paper thickness, the lid covers the outside of the body, and the longer the side fe is, the more reliable this action is. However, since the back side wall when the box lid is opened is lowered and the function as a container is lowered, the length of the side fe is made as short as possible depending on the crease insertion method, the paper type, and the like.
[0018]
When the lid is completely closed, the triangle Δfcb fits in both corners as if pressed against the back wall 9.
[0019]
In the second embodiment, even when the lid is closed and the body and the lid are kinked, the lid is securely closed so as to cover the body.
[0020]
【The invention's effect】
As described above, the body of the present invention and the hinge-folding structure of the back side wall in the two-hinge one-piece box made of a piece of paper make it possible to close the body without spilling small contents from both sides of the back wall. The lid is securely fitted, and the hinge folding part fits in the corner in the box, so that the effective volume in the box can be maximized.
[0021]
