<p>This flat bottle (1) is provided with a tube-like body (13) and a bottom (14) which closes the lower end opening of the body (13), and the flat bottle (1) is formed in a flat shape in a transverse cross-section, the flat shape having a major axis (La) and a minor axis (Sa). The bottom wall (19) of the bottom (14) is provided with an upstanding peripheral wall (21) which extends upward, an annular movable wall (22) which protrudes inward in the radial direction of the bottle from the upstanding peripheral wall (21), and a recessed peripheral wall (23) which extends upward from the movable wall. The movable wall (22) can pivot about the connection section (25) where the movable wall (22) and the upstanding peripheral wall (21) are connected. The length of the bottom (14) along the major axis (La) is in the range of 1.2 to 2.0 times, inclusive, the length of the bottom (14) along the minor axis (Sa). The length of the movable wall (22) along the major axis (La) is in the range of 0.8 to 2.5 times, inclusive, the length of the movable wall (22) along the minor axis (Sa).</p> |
