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 (1) that forms the bottom of the container, and a drum section (2) that is united to the perimeter of the bottom wall (1) and forms a filling space M for contents on the inside, and is a synthetic resin container wherein a raised bottom (1a) is formed by inverting and folding back said bottom wall (1) toward said drum section (2). Said drum section (2) has a lower peripheral wall that touches or approaches the outer wall part (1c) of said bottom wall (1) and forms a self-supporting base (9) by the inversion and folding back of said bottom wall (1).
