る必要が一切なくなった。(Effects of the Invention) As described above, the present invention provides an auxiliary piece in which a convex or concave portion that fits into the concave or convex portion formed on the inner surface of the container body is attached to the container body. Since the auxiliary piece is integrally adhered and the other smooth surface of the auxiliary piece is placed inside the container, the container body is made of a conventional resin sheet and has an uneven outer surface. Of course, it is possible to avoid any inconvenience such as the contents getting caught in the unevenness of the inner surface of the container, and also to eliminate the possibility that the contents may inappropriately infiltrate between the auxiliary piece and the container body. Since the container body may have irregularities on its inner surface, there is no need to use conventional injection molding methods, which are expensive to manufacture, for molding the container body.

にできる利点がある。Furthermore, according to the manufacturing method of the present invention, with the predetermined auxiliary pieces aligned along the outer surface of the male molding die, the resin sheet is molded into a shape along one side of these auxiliary pieces and the male molding die. By doing so, it is possible to form a container shape on the outer surface with an uneven pattern corresponding to the convex portions or concave portions of the auxiliary piece, and at the same time, the auxiliary piece can be brought into direct contact with the resin sheet to integrate the two together. This has the advantage that the process of adhering the auxiliary piece to the container body and the molding process of the container body itself can be accomplished in one process, making the series of manufacturing processes extremely simple.
