Description

本発明は、ランチボックスに関し、さらに詳しくは、コストの増加せず、廃棄しやすく、開封時にも食品の汁などで周辺を汚さず、食する時には上蓋が邪魔にならず食べやすいランチボックスに関するものである。   The present invention relates to a lunch box. More particularly, the present invention relates to a lunch box that does not increase cost, is easy to dispose, does not contaminate the surroundings with food juice even when opened, and is easy to eat without being disturbed by the top lid when eating. It is.

(主なる用途)本発明のランチボックスの主なる用途としては、朝食用、昼食用、夜食用、ピクニック用、ファーストフード用及び行動食などの種々の給食用の料理を盛るボックスであり、ランチに限るものではない。しかしながら、コストの増加せず、廃棄しやすく、開封時にも周辺を汚さず、上蓋が邪魔にならない用途のボックス状容器であれば、特に限定されるものではない。   (Main use) The main use of the lunch box of the present invention is a box serving various meals for lunch such as breakfast, lunch, evening meal, picnic, fast food and action food, and lunch. It is not limited to. However, there is no particular limitation as long as it is a box-shaped container that does not increase cost, is easy to discard, does not contaminate the periphery even when opened, and does not obstruct the upper lid.

(背景技術)お弁当やファーストフード業界では使い捨て食器として、製造が容易で、コストが安いので、発泡ポリスチレン製のランチボックスが広く使用されていた。しかしながら、耐熱性が低く、廃棄後でも自然分解性がなく環境保護の面から、紙製食器が使わるようになってきた。紙製食器は紙片を折って成形された箱状で上蓋で覆うもので、該蓋は食する時には、外側に折り返し底部に敷くが、水分や汁分が付着していることが多いので、テーブルや机上などの周辺を汚してしまうという欠点があった。また、上蓋を内側へ2つ折りに折り込むと、跳ね返るために、手で押えなくてはならないという欠点があった。さらに、上蓋を切り取ってしまうとボックス部分まで破壊したり、水分や汁分が付着した蓋が周辺を汚したり、廃棄時に別々に廃棄するので廃棄に不便であるという欠点があった。
従って、ランチボックスは、コストの増加せず、廃棄しやすく、開封時にも食品の汁などで周辺を汚さず、食する時には上蓋が邪魔にならず食べやすいものが求められている。
(Background Art) Lunch boxes made of expanded polystyrene have been widely used as disposable tableware in the lunch box and fast food industries because they are easy to manufacture and inexpensive. However, paper tableware has come to be used from the viewpoint of environmental protection because it has low heat resistance and is not naturally decomposable after disposal. Paper tableware is a box shaped by folding a piece of paper and covered with an upper lid, and when the lid is eaten, it folds outward and lays on the bottom, but often contains moisture and soup. There was a disadvantage that the surroundings such as the desk and the desk were soiled. Further, when the upper lid is folded inward, it has a drawback that it must be pressed by hand to rebound. In addition, if the upper lid is cut off, the box portion is broken, the lid to which moisture or soup is attached stains the surroundings, or is separately disposed at the time of disposal, which is inconvenient for disposal.
Accordingly, there is a need for a lunch box that does not increase cost, is easy to discard, does not stain the periphery with food soup even when opened, and is easy to eat without being disturbed by the top lid when eating.

(先行技術)従来、紙片を裁断し折線を設け、折り合わせて熱又は粘着材による貼合で成形するもので、本体の上下端に連接する位置に適当な大きさの仕切り部を設け、これら仕切り部と本体を折って圧力によるシーリングの後、仕切り部を本体に内蔵し、仕切りを有するランチボックスが知られている(例えば、特許文献1参照。)。しかしながら、収納部分のみの構成で、上蓋及びその機能については何ら記載されていない。
また、左面板と前面板と右面板と後面板と底面板群とを、折り目線を介してそれぞれ連設して、後面板の上辺に、中央で2つ折りする左右方向の折り目線を設けた蓋面板と差込み片とを、折り目線を介して順に連設して、この蓋面板に、前辺を折り目線に一致させた谷折り線で構成して、後辺を折り目線より後退させた折り目線で構成して、左右辺を適宜の切れ目線で構成した、店頭で蓋面板を中央で2つ折りして立体表示部(本発明の上蓋に相当する)を有するディスプレーカートンが知られている(例えば、特許文献2参照。)。しかしながら、立体表示部が収納部の上部へ湾曲して突出され、張り出しているので、ディスプレイには好適であるが、ランチボックスとしては食材が取り出しにくいという欠点がある。
さらに、収納箱の後面板の上辺に、中央で2つ折りする左右方向の折り目線を設けた蓋面板と差込み片とを有し、商品を収容して、店頭で蓋面板を中央で2つ折りして展示する、板紙や段ボール製のディスプレーカートンも広く知られている。しかしながら、2つ折り蓋面板(本発明の上蓋に相当する)はロックされていないので、商品が詰まっていればよいが、商品の量が減ると、跳ね上がってしまうという欠点がある。
(Prior art) Conventionally, a piece of paper is cut and provided with a fold line, folded and molded by bonding with heat or adhesive material, and a partition part of an appropriate size is provided at a position connected to the upper and lower ends of the main body. A lunch box is known that includes a partition part and a main body, and after sealing by pressure, the partition part is built in the main body and has a partition (see, for example, Patent Document 1). However, there is no description of the upper lid and its function with only the storage portion.
In addition, the left side plate, the front plate, the right side plate, the rear side plate, and the bottom plate group are connected to each other via a crease line, and a left and right crease line that folds in the middle is provided on the upper side of the rear side plate. The lid face plate and the insertion piece are connected in series through the crease line, and the lid face plate is constituted by a valley fold line whose front side is matched with the crease line, and the rear side is retracted from the crease line. A display carton having a three-dimensional display portion (corresponding to the upper lid of the present invention) that is formed by a crease line and has right and left sides formed by appropriate cut lines and is folded in two at the center at the storefront is known. (For example, refer to Patent Document 2). However, since the 3D display portion is curved and protrudes upward from the storage portion and protrudes, it is suitable for a display, but there is a drawback that it is difficult to take out food as a lunch box.
Furthermore, it has a lid surface plate and an insertion piece provided with a left and right crease line that folds in the middle on the upper side of the rear surface plate of the storage box, accommodates the product, and folds the lid surface plate in the center at the storefront. The display cartons made of paperboard and cardboard are also widely known. However, since the double-folded lid face plate (corresponding to the upper lid of the present invention) is not locked, it is sufficient that the product is jammed, but there is a drawback that it jumps up when the amount of the product is reduced.

(Blank) FIG. 2 shows a blank example in which the lunch box 10 of the present invention is developed. A bottom plate (31), a left plate (23), a front plate (25), a right plate (27), a rear plate (21), and an adhesive margin piece (29) are connected to each other via a crease line. A first upper lid plate (11), a second upper lid plate (13), and an insertion piece (15) provided with a left and right crease line (15A) that is folded in half at the center on the upper side of the rear plate (21). Are arranged in sequence through the crease line. The second lock piece (13A) formed by the cut line (1A) and the cut line (1B) and the first lock piece (11A) formed by the cut line (1C) and the cut line (1D), It is provided at a symmetrical position from the crease line (15A). Further, preferably, score line (3A) and fourth locking piece formed at a break line (3B) (13B) and cutting Looking (3C) and a third locking piece formed at a break line (3D) ( 11B) are provided symmetrically from the crease line (15A).

(ロック片)第二のロック片(13A)、第一のロック片(11A)、第四のロック片(13B)及び第三のロック片(11B)は、いずれも、図1(A)に示すように、外側に広がっているようにする。広がり形状は任意でよく、例えば、図1(A)に示す直線の台形状でも、曲線でもよく、要は外側に広がっていれば、途中で狭くしてもよい。このようにすることで、対称位置の折り目線(15A)から折り返すと、2つの片が重なり、該重なった2つの片を押し込むことで、容易にロックすることができる。
(Lock piece) The second lock piece (13A), the first lock piece (11A), the fourth lock piece (13B) and the third lock piece (11B) are all shown in FIG. As shown, spread outward. The spreading shape may be arbitrary. For example, the straight trapezoidal shape shown in FIG. 1A or a curved shape may be used. In this way, when folded back from the fold line (15A) at the symmetrical position, the two pieces overlap and can be easily locked by pushing in the two overlapping pieces.

(折り目線)折り目線(15A)は、第二のロック片(13A)と第一のロック片(11A)、第四のロック片(13B)と第三のロック片(11B)との中間に設ければよく、折り目線(15A)の位置は、第一上蓋板(11)と第二上蓋板(13)と差込み片(15)の略中央でよく、例えば、中央に設ければ、図1(B)に示すように、後面板(21)の上辺に折り畳まれる。中央より後面板(21)側に設ければ、後面板(21)に重なるように折り畳まれるので、より上部の高さを低くでき、より食べやすく、用途によって、適宜決めればよい。
(Crease line) The crease line (15A) is located between the second lock piece (13A), the first lock piece (11A), the fourth lock piece (13B), and the third lock piece (11B). The position of the crease line (15A) may be substantially at the center of the first upper cover plate (11), the second upper cover plate (13), and the insertion piece (15). As shown in FIG. 1 (B), it is folded on the upper side of the rear plate (21). If it is provided on the rear plate (21) side from the center, it is folded so as to overlap the rear plate (21), so that the height of the upper part can be lowered, it is easier to eat, and it may be determined appropriately depending on the application.

(片側ロック)切れ目線(1A)及び切れ目線(1B)で形成された第二のロック片(13A)と切れ目線(1C)及び切れ目線(1D)で形成された第一のロック片(11A)とが、折り目線(15A)から対称位置に設けられているので、上記第二のロック片(13A)と第一のロック片(11A)とが、折り目線(15A)で内側へ折り返して、2つのロック片を重ねて押し込むことで、容易に開放可能にロックできる直方体状に製箱したランチボックスとすることができる。
(One-side lock) The second lock piece (13A) formed by the cut line (1A) and the cut line (1B) and the first lock piece (11A) formed by the cut line (1C) and the cut line (1D) ) Are provided symmetrically with respect to the crease line (15A), the second lock piece (13A) and the first lock piece (11A) are folded inward along the crease line (15A). By laminating and pushing the two lock pieces, it is possible to make a lunch box made in a rectangular parallelepiped shape that can be easily opened and locked.

(両側ロック)好ましくは、さらに、切れ目線(3A)及び切れ目線(3B)で形成された第四のロック片(13B)と切れ目線(3C)及び切れ目線(3D)で形成された第三のロック片(11B)と、が上記折り目線(15A)から対称位置に設けられているので、第四のロック片(13B)と第三のロック片(11B)とが、折り目線(15A)で内側へ折り返して、各々の2つのロック片を重ねて押し込むことで、図1(B)に示すように、開放可能にロックできる直方体状に製箱したランチボックスとすることができる。開封時には、通常外側に折り返し底部に敷くが、付着している水分や汁分がテーブルや机上などの周辺を汚してしまうが、本発明では上蓋を内側へ折り返すので、例え、水分や食品の汁などが付着していても、周辺を汚すことがない。また、上蓋を内側へ2つ折りに折り込むと、跳ね返りやすく手で押えなくてはならないが、本発明では食する時にも、両側がより安定してロックされているので、手で押えることなく、また、上蓋も重なって折られていりので、邪魔にならず、極めて食べやすいのである。
(Both sides Lock) preferably further third formed by cut lines (3A) and fourth locking piece formed at a break line (3B) (13B) and cutting Looking (3C) and the score line (3D) Since the lock piece (11B) is provided at a symmetrical position from the fold line (15A), the fourth lock piece (13B) and the third lock piece (11B) are fold line (15A). Then, the two lock pieces are overlapped and pushed in, and as shown in FIG. 1 (B), a lunch box can be formed in a rectangular parallelepiped shape that can be releasably locked. At the time of opening, it is usually placed on the bottom and folded on the bottom, but the adhering moisture and juice will contaminate the periphery of the table and desk, etc., but in the present invention the top lid is folded inward, so for example moisture or food soup Even if it adheres, the surroundings are not soiled. In addition, when the upper lid is folded inward, it is easy to rebound and must be pressed by hand. In the present invention, both sides are locked more stably when eating, The upper lid is folded and overlapped, so it doesn't get in the way and is very easy to eat.

(底の構成)図2では、底面板(31)が底面板群(33+35+37+39)から構成された1例を示しているが、底部は1枚片の糊付け、組み立て底、オートロック形式などでもよい。また、仕切りを設けたり、トレーや複数の小分け皿状物を載置してもよい。   (Structure of the bottom) FIG. 2 shows an example in which the bottom surface plate (31) is composed of the bottom surface plate group (33 + 35 + 37 + 39), but the bottom portion may be a single piece of glue, an assembled bottom, an auto-lock type, or the like. . Moreover, a partition may be provided, or a tray or a plurality of subdivided dishes may be placed.

(材料)本発明のランチボックス10を構成する材料としては、特に限定されるものではないが、例えば、紙、板紙、段ボール、及びプラスチックシートや、これらの複数の積層材などが適用できる。廃棄、リサイクル性の点で紙製の材料が好ましい。   (Materials) The material constituting the lunch box 10 of the present invention is not particularly limited, and for example, paper, paperboard, cardboard, plastic sheets, and a plurality of laminated materials thereof can be applied. Paper materials are preferred in terms of disposal and recyclability.

(製造)本発明のランチボックス10の製造にあたっては、切れ目線(1A)及び切れ目線(1B)、並びに/又は、切れ目線(3A)及び切れ目線(3B)を、折り目線(15A)から対称位置に設ければよいので、従来の設備及び技術で、容易に、コストが増加することなく、製造することができる。   (Manufacturing) In manufacturing the lunch box 10 of the present invention, the cut line (1A) and the cut line (1B) and / or the cut line (3A) and the cut line (3B) are symmetrical from the fold line (15A). Since it only has to be provided at the position, it can be easily manufactured by conventional equipment and technology without increasing the cost.

(廃棄)使用後には廃棄することになるが、従来のように、上蓋材を切り取っていないので、廃棄時に別々ではなく、一体的に廃棄できるので、廃棄に便利である。また、水分や食品の汁などが付着していた上蓋でも、通常内面側に付着しているので2つ折りした際に閉じ込められているので、廃棄処理時にも手などを汚すことがない。   (Disposal) Although it will be discarded after use, since the upper lid material is not cut off as in the prior art, it can be disposed of integrally instead of at the time of disposal, which is convenient for disposal. Even the top lid to which moisture, food juice, etc. are attached is normally attached to the inner surface side and is therefore confined when folded in half, so that hands and the like are not soiled during disposal.
