う問題がある。In this case, it is preferable to store the beverage in the cold storage section in terms of quality control, and the desired taste can be maintained because the oxidation of the beverage is suppressed, but the beverage stored in the hot storage section is not oxidized. There is a problem that it is difficult to maintain the original taste due to the ink material or the inner surface coating of the metal can.
また、後者の場合は、その場で飲料を調合するものであ
るため、どうしても即席のコーヒー等に種類が限られ、
品質が劣るばかりだけでなく、容器の点でも搬送性に欠
けその場で飲まざるを得ないものである。In addition, in the latter case, since the beverage is prepared on the spot, the variety is inevitably limited to instant coffee, etc.
Not only is the quality inferior, but the container also lacks transportability, forcing the user to drink it on the spot.
以上の点から、密封可能な容器入り飲料を常時冷蔵状態
で収容しておき、需要に応じてそのまま冷蔵状態で供給
するか、あるいは販売時点で加熱して供給することが、
商品の品質維持、種類を多く取り揃えること、あるいは

ても、内容物の品質維持用として、容器原料のシートに
ガスバリアー性を確保するためのアルミニウムフィルム
がラミネートされているので、アルミニウム層がシール
ドになってマイクロウェーブによる加熱が困難となって
いる。In addition, in paper pack containers for storing milk and tea beverages, an aluminum film is laminated to the container raw material sheet to ensure gas barrier properties, in order to maintain the quality of the contents. It becomes a shield, making it difficult to heat it with microwaves.
本発明はこれら事項に鑑みてなされたもので、ガスバリ
アー性に優れているのは勿論、マイクロウェーブによる
加熱を可能ならしめた電子レンジ加熱用紙パック容器を
提供することを技術的課題とする。The present invention has been made in view of these matters, and its technical object is to provide a microwave-heated paper pack container that not only has excellent gas barrier properties but also can be heated by microwaves.

な構成とした。In order to solve the above technical problem, the present invention has the following configuration.
即ち、紙層１にガスバリアー性合成樹脂層２を重ねた積
層シートで電子レンジ加熱用紙パック容器を形成した。That is, a microwave heated paper pack container was formed from a laminated sheet in which a gas barrier synthetic resin layer 2 was laminated on a paper layer 1.
前記ガスバリアー性合成樹脂層としては、例えばポリエ
チレンテレフタレートまたはポリビニリデンフロライド
、或は、エチレン酢酸ビニル共重合体ケン化物を用いる
ことができる。As the gas barrier synthetic resin layer, for example, polyethylene terephthalate, polyvinylidene fluoride, or saponified ethylene vinyl acetate copolymer can be used.
本発明の紙層ｌにガスバリアー性合成樹脂層２を積層し
たものであるため、マイクロウェーブに対してシールド
性を持つことはない。Since the paper layer 1 of the present invention is laminated with the gas barrier synthetic resin layer 2, it does not have shielding properties against microwaves.
これにより、パック飲料を常時冷蔵状態で収容しておき
、販売時点で急加熱して供給することが容易となる。This makes it easy to store the packaged beverage in a refrigerated state at all times and then rapidly heat it and supply it at the point of sale.
したがって、自動販売機においてパック飲料を常時温蔵
しておく必要がなく、製品の品質及び味覚を長期にわた
って維持することが可能となる。Therefore, there is no need to keep the packaged beverage hot at all times in the vending machine, and the quality and taste of the product can be maintained over a long period of time.
本発明で、容器を形成する積層シートとしては、ガスバ
リアー性合成樹脂層２を有していれば、他の材質の層が
存在した３層、あるいは４層以上の積層シートであって
も良い。但ｔ１他の層として、マイクロウェーブをシー
ルドする金属層を含まないのは勿論である。In the present invention, the laminated sheet forming the container may be a laminated sheet with three layers, four or more layers in which layers of other materials are present, as long as it has the gas barrier synthetic resin layer 2. .
