［従来の技術］
近年、従来の缶詰等の容器に代わり、合成樹脂製の容器
が多く使用されている。この種の容器として、例えば、
ＡＩ！等の金属箔に合成樹脂製のフィルムをラミネート
したシートを用いた袋状容器がある。しかしながら、こ

なくてはならず、製造コストか高くなる。[Prior Art] In recent years, containers made of synthetic resin have often been used in place of conventional containers for cans and the like. Examples of this type of container include:
AI! There is a bag-shaped container that uses a sheet made of metal foil laminated with a synthetic resin film. However, when this bag-like container is heat-treated, the distance to the heating center is not uniform, so for example, the contents located near the edge are overheated, resulting in a significant deterioration in quality. . In addition, this bag-like container has low strength if left as a bag, and cannot be loaded in large quantities. In reality, each item must be packaged in a box, which increases manufacturing costs.
これに対し、積層に便利で、加熱処理に際して品質の低
下を起こさない容器として合成樹脂製の筒状本体と合成
樹脂シートからなる周壁フィルム外面及び底フィルム周
縁部とを融着させた容器が開発されている。この容器は
、個々を箱詰めにしなくても積層することができるので
、製造コストが高くならない。しかしながら、この容器
は、底面に垂直な方向の衝撃に弱く、底フィルムが破損
し易いので、積層に耐え得る強度を持たない。まり、底
面の熱伝導率に対し筒状本体の熱伝導率が低い傾向があ
るので、−゛ 加熱際し
方
て熱伝導率が悪い帯同がある。In response, a container has been developed that is convenient for lamination and does not cause quality deterioration during heat treatment, in which a cylindrical body made of synthetic resin is fused to the outer surface of a peripheral wall film made of a synthetic resin sheet and the periphery of a bottom film. has been done. This container can be stacked without being individually boxed, so manufacturing costs are not high. However, this container is weak against impact in a direction perpendicular to the bottom surface, and the bottom film is easily damaged, so it does not have enough strength to withstand stacking. In other words, since the thermal conductivity of the cylindrical body tends to be lower than that of the bottom surface, there is a tendency for the thermal conductivity to be poor during heating.

にしてもよい。In addition, in this container, since the space between the ribs of the reinforcing body is sealed with a film, the reinforcing body has a higher thermal conductivity than a synthetic resin film. With reference to FIG. 3, the case of storing and preserving food will be described. As shown in FIG. 1, on the inner surface of the female mold 1 having a cavity forming a cage-shaped reinforcing main body 5 having group ribs as shown in FIG. 2 and bottom ribs as shown in FIG. A circular film 3 having approximately the same size as the outer surface of the male mold to be inserted into the female mold is positioned. If the lower surface of this film 3 is made of synthetic resin, the other parts can be selected from various methods depending on the application.For example, CPP/A11022
It may be formed of a multilayer sheet consisting of layers. Further, this circular film 3 may be used as it is by cutting it into a circular shape in advance, or by inserting a large film into a male mold (to be described later) into a female mold and cutting it within these molds. Good too.
次に、雌型１内に雄型２を前記フィルム３が雄型に装着

The synthetic resin may be any resin as long as it can fuse the film together, and the same synthetic resin as the lower surface of the film, preferably polypropylene in this example. At this time, the film may be sheet-formed in advance, but it is preferable to simultaneously perform sheet-forming of the film and injection molding of the reinforcing body in a mold (insert molding).
この合成樹脂を固化させた後、雌型１及び雄型２を取り
