<p><P>PROBLEM TO BE SOLVED: To provide a resin molded product that can secure a required rigidity when in use, such as accommodating an article, closing a lid, or being stacked, and can perform a "volume reduction" by an easy operation and maintain this state after the volume reduction to achieve a "garbage reduction". <P>SOLUTION: A resin molded product 10 includes an inner flat surface 11 formed at the center of a part which is the bottom surface or the top plate of the resin molded product 10, an outer flat surface 12 continuing from the inner flat surface 11 via an inner rising wall 12a and surrounding the inner flat surface 11 from outside, a side wall 13 formed via the outer rising wall 12b of the outer flat surface 12, and a flange 14 formed on the opening side end of the side wall 13. The side wall 13 is formed with either one of a pushup column 15 in which its tip is oriented toward the inner flat surface 11 and a pushup rib 16 in which its tip 16a is oriented toward the inner flat surface 11. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
