<P>PROBLEM TO BE SOLVED: To obtain a paper-made molding container which has a step on a part of the container with a side face inclined toward the opening side of the upper face by drawing a sheet of paper raw material, and which can be stably stacked by utilizing the step. <P>SOLUTION: The paper-made molding container is characterized in that the container has a bottom face, a side face and a flange, the step part facing toward the outside of the container and being approximately in parallel to the bottom face is provided on the side face, and in addition, the side face has a tapered angle α in the vertical direction, the tapered angle β of the flange formed on the outer edge of the step part is smaller than α, and the relation between the thickness (paper thickness) t of the container and the height q of the flange to the step satisfies the following equation: t/sinα-t<q<t/sinα. <P>COPYRIGHT: (C)2007,JPO&INPIT |
