摘要： Disclosed is a synthetic resin container provided with an inverting, foldback bottom wall that can maintain a stable, self-supporting position while being able to minimize the amount of residual contents, and that can be formed by blow-molding, etc., and maintain the favorable producibility or low cost of the past. The synthetic resin container is provided with a bottom wall that forms the bottom of the container, and a drum section that is united to the perimeter of the bottom wall and forms a filling space M for contents on the inside, and is a synthetic resin container wherein a raised bottom is formed by inverting and folding back said bottom wall toward said drum section. Said drum section has a lower peripheral wall that touches or approaches the outer wall part of said bottom wall and forms a self-supporting base by the inversion and folding back of said bottom wall.
