Since it is a bag, it does not serve as a container and must be transferred to another container and served for dinner. In addition, the opening property is complicated because it has to be cut with scissors or torn by hand from the notch. Furthermore, even if an attempt is made to heat with a microwave oven, if the content is in a liquid state, the content cannot be heated because the content leaks from the air vent hole. As a countermeasure, there is a method of using a self-standing bag, but in this case, it is inevitable that the device will become unstable when placed on a turntable of a microwave oven. Therefore, the shape and size of the bottom surface and the height of the bag are limited.

題が生じる。On the other hand, there is a plastic molded container in which contents such as curry, stew, and soup are put, retort-sterilized, and distributed at room temperature. In this case, it can be used as tableware, so that it can be put on the table after cooking. However, the barrier property for protecting the contents is insufficient, and it is absolutely necessary to laminate a metal foil such as an aluminum foil. However, when metal foils are laminated, it is difficult to form various shapes and depths like plastic molding, and the shape and depth are limited. Regarding the openability in this case, if the lid material and the molded container are firmly adhered so that no problem occurs during sterilization or the distribution process, they cannot be opened. Problem.
そこで、この発明の課題は、密封性、バリヤー性に優

Alternatively, the cutout 10 may be provided, and this portion may be bent and expanded to separate the release layer 3 and serve as a clue to be pinched by a finger. Alternatively, although not shown, the peeling start portion may be peeled in advance.
上述の様な積層シート１と成形容器60を用いて形成し
た包装体の一例を第８、９、10図に示す。An example of a package formed using the above-described laminated sheet 1 and the molded container 60 is shown in FIGS.
まずシート１内面の熱封緘層と成形容器のフランジ部
61とを適当な位置に重ね合せて直接蓋として熱封緘し、
反対面から袋用シート100を成形容器６を挾み込むよう
にシート１と重ね合せ、周縁部を熱封緘することによっ
て成形容器を包み込んだ袋50ができあがる。図中51はシ
ール部である。なお、図では、４方シールのものを示し
たが、３方シール、合掌シールなどいずれでもよい。ま
た、図ではシート100としてシート１と同構成で切り目
８のないものを使用しているが、接着力の弱い層４のな
いものでも、用途によっては使用することができる。First, the heat sealing layer on the inner surface of the sheet 1 and the flange of the molded container
61 and heat sealed directly as a lid,
From the opposite side, the bag sheet 100 is overlapped with the sheet 1 so as to sandwich the molded container 6, and the peripheral portion is heat-sealed to complete the bag 50 enclosing the molded container. In the figure, reference numeral 51 denotes a seal portion. In the drawing, a four-sided seal is shown, but a three-sided seal, a joint seal, or the like may be used. Although the sheet 100 has the same configuration as the sheet 1 and has no cuts 8 in the drawing, a sheet without the layer 4 having a weak adhesive force can be used depending on the application.
この袋50を開封するには、前述の接着剤欠除部９にお
いて、外面剥離層３を引き起こし、そのまま上方に引張
ると、基材２と剥離層３の接着強度が樹脂層４によって
弱くなっているので、第10図のように、剥離層３が基材
２から剥離されて行く。そして、開口の部分に達する
と、切り目８が設けてあるので、基材２が剥離層３と共
に持ち上り、切り目８に沿って破断し、開口が形成され
る。この開口部より内容物を取り出せばよい。In order to open the bag 50, the outer surface peeling layer 3 is caused in the above-mentioned adhesive deficient portion 9, and when the bag 50 is pulled upward, the adhesive strength between the base material 2 and the peeling layer 3 is weakened by the resin layer 4. Therefore, as shown in FIG. 10, the peeling layer 3 is peeled off from the substrate 2. Then, when reaching the opening, the cut 8 is provided, so that the base material 2 is lifted together with the release layer 3 and breaks along the cut 8 to form an opening. The contents may be taken out from this opening.
また、例えばレトルト食品で電子レンジで加熱して食
する場合には、第８、９、10図に示す例が好適である。
即ち外面剥離層３として、例えばアルミニウム箔の両面
にポリエステルフィルムを貼り合せたもの、基材２とし
て、ポリエステルと無延伸ポリプロピレンフィルムの積
層体を用い、成形容器60としてはポリプロピレンの成形
品を使用すると、レトルト殺菌処理を行うことによって
常温流通で長期保存が可能となる。For example, in the case of eating a retort food by heating in a microwave oven, the examples shown in FIGS. 8, 9 and 10 are preferable.
That is, for example, when a polyester film is bonded to both surfaces of an aluminum foil as the outer surface release layer 3, a laminate of polyester and a non-stretched polypropylene film is used as the base material 2, and a molded polypropylene product is used as the molding container 60. By performing retort sterilization, long-term storage at room temperature is possible.
いま、内容物としてシチューとかスープなどを想定し
た場合、加熱して食することとなる。そこでシート100
の外面剥離層３を除去し、次にシート１の外面剥離層３
を剥離除去する。そうするとマイクロ波を透過する材料
より成り、ポリプロピレン成形容器の開口部が開かれた
袋となる。この袋の両端部分をつかんで電子レンジに入
れ加熱し、そのまま食卓に出せばよく、他の容器に移し
替える必要がない。Now, assuming a stew or soup as a content, the food is heated. So sheet 100
Of the outer surface release layer 3 of the sheet 1 and then the outer surface release layer 3 of the sheet 1
Is peeled off. Then, the bag is made of a material that transmits microwaves, and the opening of the polypropylene molded container is opened. You just have to grab both ends of this bag, put it in a microwave oven, heat it and put it out on the table as it is, without having to transfer it to another container.
また、上記例では、電子レンジ加熱前に既に開口部が
形成されたが、外面剥離層３と基材２との接着強度を適
度に調整することにより、外面剥離層３を剥離除去した
段階では開口部が形成されず、切り目８がそのまま基材
２に残存するようにし、電子レンジ加熱後切り目８を引
張って開口を形成してもよい。この場合電子レンジ加熱
中に発生する水蒸気が成形容器内に適度に保持されるた
め、食品によっては良好な調理効果が得られる。Further, in the above example, the opening was already formed before heating in the microwave oven, but by appropriately adjusting the adhesive strength between the outer surface peeling layer 3 and the base material 2, at the stage where the outer surface peeling layer 3 was peeled off. An opening may not be formed, and the cut 8 may remain in the base material 2 as it is, and after the microwave oven is heated, the cut 8 may be pulled to form the opening. In this case, since the steam generated during the heating in the microwave oven is appropriately held in the molding container, a good cooking effect can be obtained depending on the food.
電子レンジによる加熱後には、成形容器の周囲の袋の
部分は熱くなっていないので手でつかみ易い。After heating by the microwave oven, the bag around the molding container is not hot, so it is easy to grasp by hand.
