<p>PROBLEM TO BE SOLVED: To provide a plastic container whose bottom part can easily be deformed, and for which the total height of the container can be suppressed.SOLUTION: A plastic container 10 has an opening part 11, a barrel part 12 and a bottom part 13. The bottom part 13 has an inflection part 13a and a grounding part 13b connected to an outer peripheral edge of the inflection part 13a through a fulcrum part 13c. When the bottom part 13 is pushed up, the inflection part 13a is dented inward around the fulcrum part 13c. Since the fulcrum part 13c is positioned above the grounding part 13b, a position of the grounding part 13b is kept fixed so that the dispersion in the total height of the container can be suppressed.</p> |
