コストが割高であった。2. Description of the Related Art A conventional packaging container is made of plastic, and a thermoformed tray is generally covered with a heat seal lid made of a plastic film. On the other hand, some packaging containers were made of paperboard, but the folded lap joints of the containers were fixed with an adhesive or the like to complete the container. However, such joints are often separated, and there is a disadvantage that the fluid easily leaks from that location. In some cases, a plastic film was attached to the surface of a paper packaging container, but the manufacturing process was complicated and the manufacturing cost was relatively high.

FIG. 1 is a developed view of a paperboard used in the present invention, and FIG. 2 is a perspective view of an assembled state of the paperboard. First, a blank 1 is formed by punching a paperboard of about 0.1 to 1 m / m into a predetermined shape so as to become a container. The blank 1 of this embodiment includes a bottom piece 2, side pieces 3, 4, 5, and 6, flange pieces 7, 8, 9, 10, and four corner side pieces 11, which are connected to the side pieces.
12, 13, and 14. Further, the connection portion 15 between the flange pieces 7, 8, 9, and 10 is in a state of being abutted. As another embodiment of the seam of the connecting portion between the brim pieces, a thing of a real tongue 16 as shown in FIG. 3 is employed. Thereafter, the blank 1 is placed in the half mold 17, and the blank 1 is sucked from below by the vacuum pump 18, and is brought into close contact with the half mold 17. Thereafter, an impermeable film 19 is formed on the upper surface of the blank 1 provided in the half mold 17.
Is disposed, and the film 19 is sucked from below by a vacuum pump 18 through a gap or the like formed in the blank 1,
Adhere to the blank 1 surface. Thereafter, the edge of the film adhered to the blank surface is cut along the edge of the blank 1.

However, the pulp impregnated with the resin is preformed by using a vacuum, and then the container having a predetermined shape is formed by pulp molding that is dried in a furnace and compression molded. Alternatively, a means for performing the operation may be employed. An impermeable container can be completed by sequentially performing the same steps as above on this container. Further, all the pulp materials used in the above pulp molding can be used paper.

状態が良好となる。As described in detail above, according to the method for manufacturing a packaging container of the present invention, a water-impermeable film is applied to the inner surface of a paper container or a container formed by pulp molding by an extremely simple method. I can wear it. Further, since a paper piece is used, it can be burned as compared with a conventional plastic one, and there is no fear of causing a pollution problem. Further, by employing a vacuum pump, the vacuum dispersion is made uniform with respect to the paper container, and the water-impermeable film is in good contact with the inside corner of the container without pinholes or the like.
