電子レンジ加熱可能な自立袋とその包装体並びに該自立袋の作製方法Self-supporting bag that can be heated by microwave oven, its package, and method for producing the self-supporting bag

本発明は、食品等を収容する自立袋に関し、特には、電子レンジ等の加熱手段を用いて加熱した時、発生する蒸気の力で自立袋の開口を行う電子レンジ加熱可能な自立袋とその包装体並びに該自立袋の作製方法に関する。   The present invention relates to a self-supporting bag that contains food, etc., and in particular, a self-supporting bag capable of microwave heating that opens the self-supporting bag with the force of generated steam when heated using heating means such as a microwave oven, and the like The present invention relates to a package and a method for producing the self-supporting bag.

従来、調理済みの、あるいは半調理済の食品等を耐熱性のプラスチックフィルムからなる包装袋に充填して、食する直前に電子レンジにより加熱して調理する包装食品が提案されている。   2. Description of the Related Art Conventionally, packaged foods have been proposed in which cooked or semi-cooked food or the like is filled in a packaging bag made of a heat-resistant plastic film and heated by a microwave oven immediately before eating.

しかし、この包装食品は電子レンジで加熱すると、加熱時に食品等から発生する蒸気圧などの内圧により、包装袋が破裂して内容物が飛散してしまい、電子レンジの内部を汚染してしまう欠点があった。   However, when this packaged food is heated in a microwave oven, the packaging bag ruptures and the contents are scattered due to internal pressure such as vapor pressure generated from the food during heating, and the contents of the microwave oven are contaminated. was there.

このため、電子レンジで加熱する前に、あらかじめ、包装袋に、例えば、ハサミ等を用いて小さい孔等を開けて、あるいは、袋の一部を切り取って、包装袋内部の内圧の上昇を抑えて包装袋の破裂を防止していた。   For this reason, before heating in a microwave oven, a small hole etc. are opened in a packaging bag beforehand, for example using scissors, or a part of a bag is cut off, and the rise in internal pressure inside a packaging bag is suppressed. The packaging bag was prevented from rupturing.

しかしながらこの方法では、加熱後発生する水蒸気は、直ぐに包装袋の外に放出されてしまうため、水蒸気による蒸し調理効果が低減されるとともに、包装袋内部の食品の乾燥が進行して、食品の劣化をきたす場合がある。   However, in this method, water vapor generated after heating is immediately released out of the packaging bag, so that the steaming cooking effect by the water vapor is reduced, and the food inside the packaging bag is dried, resulting in deterioration of the food. May result.

これらの問題を解消すべく、例えば、図3に示すような、あらかじめ、内容物充填口付近の内容物側に側部シール(103)に隣接してシールエリア(101)を設け、このシールエリアの中心に袋内で発生した蒸気を抜くための小孔(102)を開けておくことで、包装袋を自立させたまま電子レンジで加熱して、内圧により包装袋が膨張したとき、シールエリア(101)に応力が集中し、シールエリア(101)が剥離してシール後退することで、蒸気が小孔(102)から抜けるようにしたものがある。   In order to solve these problems, for example, as shown in FIG. 3, a seal area (101) is provided in advance on the content side near the content filling port adjacent to the side seal (103). By opening a small hole (102) for removing the steam generated in the bag at the center of the bag, it is heated in a microwave oven while the packaging bag is self-supported. In some cases, the stress concentrates on (101), the seal area (101) peels off, and the seal moves backward so that the vapor can escape from the small hole (102).

しかし、このタイプでは、袋の内側に張り出したシールエリアにより充填口付近が狭くなっているため、充填不良等の原因になり易い。また、包装袋の容積が袋の内側に張り出したシールエリアにより小さくなっているため、同じサイズの包装袋に比較して内容量が少なくなるという問題がある。
特開2005−059868号公報
However, in this type, since the vicinity of the filling port is narrowed by the seal area that protrudes inside the bag, it tends to cause a filling failure or the like. Moreover, since the volume of the packaging bag is smaller due to the seal area projecting inside the bag, there is a problem that the inner volume is reduced as compared with the packaging bag of the same size.
JP 2005-059868 A

本発明を一実施形態に基づいて以下に詳細に説明する。
本発明の電子レンジ加熱可能な自立袋は、例えば、図1に示すように、相対向する表裏二枚の胴部材フィルム(11a、11b)の間に別体の断面が逆V字状に二つ折りされた底部材フィルム(12)を介在させて、放物線状に接着された底部シール(13)と、直線状に接着された二本の側部シール(14、14)とを形成させた底ガセット方式の自立袋である。
The present invention will be described in detail below based on one embodiment.
The self-supporting bag capable of being heated in a microwave oven according to the present invention has, for example, two separate V-shaped cross-sections between two front and back body member films (11a, 11b) as shown in FIG. A bottom in which a bottom seal (13) bonded in a parabolic shape and two side seals (14, 14) bonded in a straight line are formed by interposing a folded bottom member film (12) It is a gusseted self-supporting bag.

そして、表裏二枚の胴部材フィルムのうち、表側の胴部材フィルム(11a)には横方向の二本の互いに平行な折り曲げ線(山折り線(a)と谷折り線(b))により外方に突出する折り込み部(15)が横幅全体にわたって形成されている。   Of the two body member films on the front and back sides, the body member film (11a) on the front side is separated by two parallel fold lines (mountain fold line (a) and valley fold line (b)). A fold (15) projecting in the direction is formed over the entire width.

折り込み部(15)の内側には、易剥離性を有するイージーピールテープ(16)が折り込み部全体にわたってイージーピール面(16a)を外側、強接着面(16b)を内側にして挿入され熱接着されている。   Inside the folding part (15), an easy peel tape (16) having easy peelability is inserted and thermally bonded across the entire folding part with the easy peel surface (16a) on the outside and the strong adhesive surface (16b) on the inside. ing.

突出する折り込み部(15)の中央付近の折り曲げ線(山折り線(a))近傍は、狭幅のシール幅となる切り欠き(17)が設けられている。   In the vicinity of the fold line (mountain fold line (a)) in the vicinity of the center of the projecting fold (15), a notch (17) having a narrow seal width is provided.

胴部材フィルム(11)や底部材フィルム(12)の材質構成に制約はなく、通常の自立袋用の材質構成が適用できる。具体的な構成例を示すならば、例えば、〔外側〕ポリエチレンテレフタレートフィルム/ナイロン/ポリエチレン〔内側〕、〔外側〕二軸延伸ポリプロピレンフィルム/未延伸ポリプロピレン〔内側〕〔外側〕一軸ないし二軸延伸されたポリエチレンテレフタレートフィルム上に、酸化アルミニウムや酸化ケイ素などの無機化合物の薄膜を物理蒸着あるいは化学蒸着などの蒸着法により20〜100nm程度の厚さに設けた無機化合物蒸着ポリエチレンテレフタレートフィルム/ナイロン/未延伸ポリプロピレン〔内側〕等が例示できる。   There is no restriction | limiting in the material structure of a trunk | drum member film (11) and a bottom member film (12), and the material structure for normal self-supporting bags is applicable. For example, [outside] polyethylene terephthalate film / nylon / polyethylene [inside], [outside] biaxially stretched polypropylene film / unstretched polypropylene [inside] [outside] uniaxially or biaxially stretched An inorganic compound-deposited polyethylene terephthalate film / nylon / unstretched with a thin film of an inorganic compound such as aluminum oxide or silicon oxide formed on a polyethylene terephthalate film by a vapor deposition method such as physical vapor deposition or chemical vapor deposition. Examples include polypropylene [inside].

なお、ボイル・レトルト殺菌やオートクレーブ殺菌を必要としない場合には、イージーピールテープを挿入せず、シーラントフィルム自体でシールするタイプとすることもできる。
Since the self-supporting bag which can be heated in a microwave oven having such a structure is excellent in heat resistance, it can be applied to contents requiring boil / retort sterilization or autoclave sterilization.
In addition, when boil / retort sterilization or autoclave sterilization is not required, an easy peel tape may not be inserted, and the sealant film itself may be used.

この際使用するシーラントフィルムは、シール条件(温度,圧力)によってシール強度に違いが出るタイプであれば良く、例えば、トーセロT.A.F(東セロ株式会社製)のようなイージーピール性を有するフィルムであればなお良い。このフィルムを使用した場合、蒸気抜きとなる切り欠き部分は160°Cにてシールして400gf/15mmのシール強度となり、その他の部位は170°C〜180°Cでシールして600gf/15mmのシール強度となる。   The sealant film used in this case may be of a type in which the seal strength varies depending on the sealing conditions (temperature, pressure). A. Any film having an easy peel property such as F (manufactured by Tosero) may be used. When this film is used, the notch portion for removing steam is sealed at 160 ° C. to give a sealing strength of 400 gf / 15 mm, and the other portions are sealed at 170 ° C. to 180 ° C. to 600 gf / 15 mm. Seal strength.

つぎに、本発明の電子レンジ加熱可能な自立袋の作製方法について述べる(図2参照)。
先ず、胴部材フィルム(11)を流れ方向に沿って二つ折りすると同時に、二つ折りされた一方のフィルム(11a)の端縁近傍に、流れ方向に沿って外方に突出する折り込み部(15)を帯状に連続して形成する。〜胴部材フィルム二つ折り・折り込み部形成工程(A)
