PROBLEM TO BE SOLVED: To provide a plastic container which is excellent in buckling strength and side wall strength and absorbs fluctuations of a pressure even when the interior of the container is decompressed or pressurized.SOLUTION: A plastic container 10 includes: a mouth part 11; a shoulder part 12; a trunk part 20; and a bottom part 30. The trunk part 20 includes: multiple pressure absorbing panels 40 which are arranged along a circumferential direction; and vertical support pillars 21, each of which is disposed between the pressure absorbing panels 40 and extends in a vertical direction. Each pressure absorbing panel 40 is provided with multiple protruding ribs 41 protruding outward and recessed ribs 42 positioned between the protruding ribs 41. Each protruding rib 41 and each recessed rib 42 extend from one end 40a of each pressure absorbing panel 40 to the other end 40b so as to form V shapes. |
