Description

本発明は、コンビニエンスストア、スーパーマーケット、一般商店で販売されるテイクアウトできる食品、例えばコロッケ、メンチカツ、ハンバーガー等の食品を包装する薄いフイルムで形成された食品包装用袋に関する。   The present invention relates to a food packaging bag formed of a thin film for packaging foods that can be taken out, such as croquettes, rice cutlets, and hamburgers, that are sold in convenience stores, supermarkets, and general stores.

透明な熱可塑性合成樹脂フイルムに品名、店名等を印刷した紙を重合して袋にした食品包装用袋は公知である。
従前公知のこの種食品包装用袋は、熱可塑性合成樹脂フイルムと紙とを重合接着した矩形フイルムをその中間部でひだ折りし、熱可塑性合成樹脂フイルムが内側になるよう二つ重ねにし、その両側縁をヒートシールして構成したものである。 A food packaging bag is known which is obtained by polymerizing a paper in which a product name, a store name, etc. are printed on a transparent thermoplastic synthetic resin film.
This kind of conventionally known food packaging bag is formed by folding a rectangular film obtained by polymerizing and bonding a thermoplastic synthetic resin film and paper at its middle portion, and then stacking the two so that the thermoplastic synthetic resin film is on the inside. The side edges are heat sealed.

従来公知の上記食品包装用袋は、この袋内に食品を収めて所持すること又は食品を食べながら所持することには何ら不都合はなく、この食品包装袋の目的は充分達成されている。
しかし、この公知の食品包装用袋は、そのひだ折りした底部に安定性がないことにより、食品を収めた状態でテーブル上に立てることができないという課題があった。
本発明は、この食品包装用袋をその中に食品を収めた状態で、テーブル上に立てることができるようにすることを目的とする。 The above-described food packaging bag known in the art has no inconvenience for holding and holding food in the bag, and the purpose of the food packaging bag is sufficiently achieved.
However, this known food packaging bag has a problem that it cannot be stood on a table in a state in which food is stored because the folded fold bottom portion is not stable.
An object of the present invention is to enable the food packaging bag to stand on a table in a state where food is contained therein.

そのため、本発明の食品包装用袋は、熱可塑性合成樹脂フイルムと紙とを重合接着した矩形フイルムをその中間部でひだ折りし、熱可塑性合成樹脂フイルムが内側になるよう二つ重ねにし、その両側縁をヒートシールして構成した食品包装用袋であって、上記ひだ折りして形成された底の両端の縁の重合部を接着してあることを特徴とする。   Therefore, in the food packaging bag of the present invention, a rectangular film obtained by polymerizing and bonding a thermoplastic synthetic resin film and paper is folded at an intermediate portion thereof, and the thermoplastic synthetic resin film is folded in two so as to be inside. A food packaging bag constructed by heat-sealing both side edges, wherein the overlapping portions at both ends of the bottom formed by folding the folds are adhered.

また、本発明の食品包装用袋は、展開状態で、上記ひだ折りされる二つの区分の両端に透孔を形成し、ひだ折りにして形成された底の両端縁の重合部をヒートシールした際に、該透孔を介して向き合う熱可塑性合成樹脂フイルムがヒートシールされて接着されたことを特徴とする。   In addition, the food packaging bag of the present invention, in the unfolded state, formed through holes at both ends of the two fold-folded sections, and heat-sealed the overlapping portions at both ends of the bottom formed by fold-folding. In this case, the thermoplastic synthetic resin film facing through the through holes is heat sealed and bonded.

さらに、本発明の食品包装用袋は、熱可塑性合成樹脂フイルムと紙とを重合した矩形フイルムであって、一端側に紙が重合されない熱可塑性合成樹脂フイルムだけの部分を有し、二つ重ねにした際に該紙が重合されていない熱可塑性合成樹脂フイルムのみの部分が紙の重合された部分より張り出していることを特徴とする。   Further, the food packaging bag of the present invention is a rectangular film obtained by polymerizing a thermoplastic synthetic resin film and paper, and has a portion of only the thermoplastic synthetic resin film on which the paper is not polymerized on one end side. In this case, the portion of the thermoplastic synthetic resin film alone in which the paper is not polymerized is projected from the polymerized portion of the paper.

本発明の食品包装用袋は、熱可塑性合成樹脂フイルムと紙とを重合接着した矩形フイルムをその中間部でひだ折りし、熱可塑性合成樹脂フイルムが内側になるよう二つ重ねにし、その両側縁をヒートシールして構成した食品包装用袋であって、上記ひだ折りして形成された底の両端の縁の重合部を接着してあることを特徴とするから、袋中に食品を入れた状態で、底を拡げることができ、食品を入れた食品包装用袋をテーブル上に立てることができる効果がある。   The food packaging bag of the present invention has a rectangular film obtained by polymerizing and bonding a thermoplastic synthetic resin film and paper at the middle portion thereof, folded in two so that the thermoplastic synthetic resin film is on the inside, and both side edges thereof A food packaging bag constructed by heat-sealing, characterized in that the overlapping portions at both ends of the bottom formed by folding the folds are adhered, so that food is put in the bag. In the state, the bottom can be expanded, and there is an effect that the food packaging bag containing the food can be set on the table.

また、本発明の食品包装用袋は、展開状態で、上記ひだ折りされる二つの区分の両端に透孔を形成し、ひだ折りにして形成された底の両端縁の重合部をヒートシールした際に、該透孔を介して向き合う熱可塑性合成樹脂フイルムがヒートシールされて接着されたことを特徴とするから、簡単な構造及び簡単な手段で本発明食品包装用袋を生産することができる効果がある。   In addition, the food packaging bag of the present invention, in the unfolded state, formed through holes at both ends of the two fold-folded sections, and heat-sealed the overlapping portions at both ends of the bottom formed by fold-folding. In this case, the thermoplastic synthetic resin film facing through the through holes is heat-sealed and bonded, so that the food packaging bag of the present invention can be produced with a simple structure and simple means. effective.

図６乃至図８に公知の食品包装用袋が示してある。図６の展開図及び図７の断面図に示すように、この食品包装用袋は、透明な熱可塑性合成樹脂フイルム１と紙２とを重合接着した矩形フイルムをその中間部で３本のひだ折り線３に沿ってひだ折りし、熱可塑性合成樹脂フイルム１が内側になるよう二つ重ねにし、その両側縁をヒートシールして食品包装用袋を構成してある。
熱可塑性合成樹脂フイルムは、その一端側に紙２と二つ重ねにしていない部分１’を有し、この部分１’により張り出し部が構成される。 A known food packaging bag is shown in FIGS. As shown in the developed view of FIG. 6 and the cross-sectional view of FIG. 7, this food packaging bag is composed of a rectangular film obtained by polymerizing and bonding a transparent thermoplastic synthetic resin film 1 and paper 2 with three pleats in the middle. A food packaging bag is constructed by folding the folds along the fold line 3 so that the thermoplastic synthetic resin film 1 is placed inside, and heat-sealing both side edges.
The thermoplastic synthetic resin film has a portion 1 ′ that is not overlapped with the paper 2 on one end side, and this portion 1 ′ forms an overhanging portion.

この公知の食品包装用袋は、図８の断面図に示されるように、ひだ折りされた底の表面が紙２により形成されるから、袋に形成する際に縁をヒートシールしても底４の縁は接着されない。従って、底４は底として形成されるが、その縁が接着されていないため、底として安定性がなく食品包装用袋を立てることができない。   As shown in the cross-sectional view of FIG. 8, this known food packaging bag has a fold-folded bottom surface formed of paper 2. Therefore, even when heat-sealing the edge when forming the bag, the bottom The edge of 4 is not glued. Therefore, the bottom 4 is formed as a bottom, but since the edge is not adhered, the bottom is not stable and cannot stand a food packaging bag.

図１乃至図５に本発明の食品包装用袋が示してある。この図１乃至図５中、図６乃至図８に示した符号と同一の部分は同じ部分である。本発明の特徴は、上記ひだ折り線３，３によってひだ折りされて構成された底４を形成する二つの区分５，５の両端の重合部分を接着することである。このことにより底４の両端部分が接着固定され底４を開いたとときに、この接着固定部分が強固となり、安定する。   1 to 5 show a food packaging bag according to the present invention. 1 to 5, the same parts as those shown in FIGS. 6 to 8 are the same parts. A feature of the present invention is that the overlapping portions at both ends of the two sections 5 and 5 forming the bottom 4 formed by folds by the fold lines 3 and 3 are bonded. As a result, when both end portions of the bottom 4 are bonded and fixed and the bottom 4 is opened, the bonded and fixed portion becomes strong and stable.

そこで、本発明では、上記ひだ折り線３によって囲まれた二つの区分５，５の両端に透孔６，６を形成し、ひだ折り線３に沿ってひだ折りして底を形成し、二つ重ねにして袋を形成するために両縁７，７をヒートシールした際に、上記透孔６，６を介して向き合う熱可塑性合成樹脂フイルムがヒートシールされて、底４の両端が重合接着される。   Therefore, in the present invention, the through holes 6 and 6 are formed at both ends of the two sections 5 and 5 surrounded by the fold fold line 3, and the bottom is formed by fold along the fold fold line 3. When both edges 7 and 7 are heat-sealed to form a pouch, the thermoplastic synthetic resin films facing each other through the through-holes 6 and 6 are heat-sealed, and both ends of the bottom 4 are polymerized and bonded. Is done.
