〔産業上の利用分野〕
この発明は、食品等を収納して、電子レンジで調理可能
な包装用容器に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a packaging container that stores foods and the like and can be cooked in a microwave oven.
従来、カレー、シチュー等をプラスチックの容器本体に
充填し、この容器本体に蓋材をヒートシールによって接
着して密封包装したインスタント食品がある。BACKGROUND ART Conventionally, there are instant foods in which curry, stew, etc. are filled into a plastic container body, and a lid material is adhered to the container body by heat sealing to seal the container.
ところで、この種の包装に使用される蓋材は、バリヤー
性を向上させるために、アルミニウム箔等の金属薄膜層
を含む積層材によって形成されていることが多い。Incidentally, the lid material used for this type of packaging is often formed of a laminated material containing a metal thin film layer such as aluminum foil in order to improve barrier properties.
ところが、カレー、シチュー等の内容物を電子レンジに
よって加熱する場合、蓋材を形成する積層材の一層に金
属薄膜層があると１ｉｒＩＩｉ波が遮断されるため、蓋
材を容器本体から完全に除去した後、容器本体の開口部
をラップフィルム等で覆う必要があった。However, when heating the contents of curry, stew, etc. in a microwave oven, if there is a metal thin film layer on one layer of the laminated material that forms the lid, the 1irIIi waves will be blocked, so the lid must be completely removed from the container body. After that, it was necessary to cover the opening of the container body with cling film or the like.
そこで、この発明の目的は、上記のような手間を省（た
め、蓋材の金属薄膜層の部分のみを除去することができ
、従ってそのままで調理可能な包装用容器を提供するこ
とである。Therefore, an object of the present invention is to provide a packaging container in which only the metal thin film layer of the lid material can be removed and can be used for cooking as is, thereby saving the above-mentioned effort.
上記の目的を達成するため、この発明においては、少な

容器を構成したのである。In order to achieve the above object, in this invention, a metal thin film layer is applied to the outer surface of a base material whose at least the inner surface is heat sealable and includes a base film via an adhesive layer and a resin layer having a weaker adhesive strength. Laminated gas barrier layers containing
A lid material in which the gas barrier layer portion can be manually peeled off from the base material is heat-sealed to the opening flange of the container body, and a small (half-cut that penetrates the base material) is sealed at the tab portion of the lid material. The packaging container is constructed by forming the lid across the entire lid material in a direction transverse to the unsealing direction, and by providing a tearing portion of the lid material near the tip of the tab portion.

波を反射しないから、そのまま電子レンジで調理するこ
とができる。Since the tab portion of the lid material has a half cut across the opening direction, by tearing the tearing portion of the lid material at the tip of the tab portion, the barrier layer including the metal thin film layer is bonded to the base material at the half cant portion. Since the metal thin film layer is separated and the base material is exposed, it is only necessary to start peeling between the base material and the tear part.Since this metal thin film layer is laminated with the base material via a resin layer with weak adhesive strength, By continuing the unsealing operation, the metal thin film layer can be easily removed. When this is removed, the lid material and the container body made of synthetic resin remain, and since they do not reflect electromagnetic waves, they can be used as they are for electronic transmission. Can be cooked in the microwave.
また、調理後は易開封合成樹脂基材より成る蓋材に形成
されているタブにより、容器本体から容易に開封するこ
ともできる。Further, after cooking, the container can be easily opened from the container body using a tab formed on the lid made of an easy-to-open synthetic resin base material.

5 are laminated. Incidentally, it is preferable to provide a surface protection layer 6 on the outer surface of the metal thin film layer 5. This layer 6 is formed by coating with a synthetic resin or bonding a synthetic resin film. It is also possible to provide a printed layer on the outer surface of layer 5 and on the outer surface of layer 6.

い。The resin layer 3 is made of a resin with relatively low adhesive strength, such as an acrylic resin, a polyamide resin, a silicone resin, a vinyl resin, etc. alone or in a mixture, and is formed by partially applying (part coating) these resins. Examples of coating patterns that are best formed are shown in Figures 3 (a), (b), and 3. As shown in the figure, the portions to which the resin is not applied form patterns such as lines, dots, and grids. Note that, depending on the case, the layer 3 may be formed by coating the entire surface with the resin.Also, the layer 3 may be provided on the surface of the base material 2 as shown in FIG. In short, the resin layer 3 may be provided at the interface of the adhesive layer 4.

基材２は分離し、容器本体１ｏに残る。In order to use this container for cooking, it must be torn in a direction transverse to the half-cut 8 from the through-cut 16 at the tip of the tab of the lid 1 shown in FIG. At this time, the base material 2 remains on the side of the container 10, and the metal thin film layer 5 is partially removed as shown in FIG.
As shown in the sectional view of the tab portion AA shown in FIG. 8, only the base material remains. Therefore, next, just pinch the exposed portion of the base material 2 and the lid material 1 at the tip of the tab portion 15 and separate the metal thin film layer 5. Then, the base material 2 will be separated from the lid material 1, and the container It remains in the main body 1o.
そこでこの容器を電子レンジに入れて調理すればよい。Then you can put this container in the microwave and cook it.

Since a tearing part of the lid material is provided in the part, there is no risk that the barrier properties will be impaired by half-cutting, and deterioration of the contents can be effectively prevented. Since there is no breakage at the tearing part, and the base material can be partially exposed at the tab part, the metal thin film layer can be easily removed, and the metal thin film layer can be used for cooking in a microwave oven. Just remove it and you can use it as is.
また、内容物取り出し時において、タブが存在している
