２は、極めて成形しやすい状態となる。First, the packaging material 2 undergoes a softening process. This softening process includes the heater section 7 provided above the packaging material 2, which is the side of the thermoplastic synthetic resin sheet 2a, and the cardboard 2b.
This is performed by the humidifying section 8 provided below the packaging material 2 on the side of. The sheet 2 a of thermoplastic synthetic resin is heated by the heater unit 7. A heating temperature of about 180 to 250 ° C is suitable. On the other hand, the cardboard 2b is humidified by the humidifying section 8. Since the thermoplastic synthetic resin has the property of being softened by heat and the paper being softened by moisture respectively, both the thermoplastic synthetic resin sheet 2a and the cardboard 2b are softened, and as a result, the packaging material 2 is in an extremely easy-to-form state. Become.
【００２４】軟化工程は、上記の方法以外に、包装材２

は、包装材２の送り出しを停止させることが望ましい。Next, the packaging material 2 undergoes a molding process in the molding section 9. This molding process is performed by a press molding device. The softened packaging material 2 is molded into a container shape by the mold of this molding apparatus, and the side surface 3 and the bottom surface 4 of the container 1 are formed. In addition to the press molding, vacuum molding or pressure molding may be used. It is desirable to stop the delivery of the packaging material 2 during the operation of the molding apparatus.

で搬送されていくようになっている。Then, by the cutting process in the next cutting section 11, the individual packaging containers 1 are successively processed from the packaging material 2 which has undergone the cooling process.
Are separated. In this cutting step, an automatic puncher is used, and the boundary between the necessary portion that constitutes the container 1 and the unnecessary portion that does not constitute the container 1 of the packaging material 2 that is sequentially fed is cut, and the container 1 is completed one after another.
