CONTAINER MADE OF SYNTHETIC RESIN

PROBLEM TO BE SOLVED: To provide a container made of synthetic resin comprising a pressure reduction absorbing panel capable of achieving sufficient pressure reduction absorbing performance without causing any appearance defect, while facilitating reduction in weight and thickness of the container, without impairing reversible deformation of the pressure reduction absorbing panel, and equally deforming the respective pressure reduction absorbing panels disposed in the container body part.SOLUTION: A container made of synthetic resin comprises panel bodies 61 of pressure reduction absorbing panels 6, each of which includes: a center part 62 height-wise extending in the center part of a circumferential direction; and two panel dividing parts 63 arranged on both sides of the center part 62 and circumferentially curved from the center part 62 sides. A panel shape is configured with a plurality of crossing grooves 65 which circumferentially extend from respective one ends of the panel dividing parts 63 on the center part 62 side to the other ends and which are height-wise aligned in parallel in each of the panel dividing parts 63.SELECTED DRAWING: Figure 1 【課題】容器の軽量化、薄肉化を図りながらも、減圧吸収パネルの可逆的な変形を妨げることなく、容器胴部に配設された複数の減圧吸収パネルのそれぞれを均等に変形させて、外観不良を生じることなく、十分な減圧吸収性能を発揮することができる減圧吸収パネルを備えた合成樹脂製容器を提供する。【解決手段】減圧吸収パネル６のパネル本体６１を、その周方向中央部に高さ方向に沿って延在する中央部６２と、この中央部６２の両側に位置し、中央部６２側から周方向に沿って湾曲する二つのパネル分割部６３とを備え、それぞれのパネル分割部６３に、中央部６２側のパネル分割部６３の一端から周方向に延びて他端に至る複数の横断溝部６５が、高さ方向に沿って列設されたパネル形状とする。【選択図】 図１
