FLAT BOTTLE

摘要

The flat bottle includes a cylindrical body and a bottom closing a lower opening of the body, and is formed in a flattened shape in lateral cross-section having a major axis (La) and a minor axis (Sa). A bottom wall of the bottom includes a rising circumferential wall extending upward; an annular movable wall projecting inward from the rising circumferential wall in a bottle radial direction; and a recessed circumferential wall extending upward from the movable wall. The movable wall is movable around a connected portion with the rising circumferential wall. The length of the bottom along the major axis is 1.2 to 2.0 times the length of the bottom along the minor axis. The length of the movable wall along the major axis is 0.8 to 2.5 times the length of the movable wall along the minor axis.

1. A flat bottle comprising a cylindrical body portion and a bottom portion which closes a lower opening section of the body portion, and the flat bottle having a flattened shape in lateral cross-section which has a major axis and a minor axis perpendicular to each other at a point on a bottle axis,
wherein a bottom wall portion of the bottom portion comprises:
a grounding portion positioned at an outer circumferential edge of the bottom wall portion;a rising circumferential wall portion connected to an inside of the grounding portion in a bottle radial direction and extending upward;an annular movable wall portion projecting from an upper end part of the rising circumferential wall portion toward inside of the rising circumferential wall portion in the bottle radial direction; anda recessed circumferential wall portion extending upward from an inner end of the movable wall portion in the bottle radial direction, wherein the movable wall portion is arranged to be movable around a connected portion between the movable wall portion and the rising circumferential wall portion so as to move the recessed circumferential wall portion upward, a length of the bottom portion along the major axis is 1.2 to 2.0 times a length of the bottom portion along the minor axis, and a length of the movable wall portion along the major axis is 0.8 to 2.5 times a length of the movable wall portion along the minor axis.
