Synthetic resin bottle

Tanaka of Yoshino Kogyo Co., Ltd., Japan, developed vacuum absorbing panels that can control swelling deformation involved in hot filling of synthetic resin bottles, without impairing the vacuum absorbing function of the bottles.  It consists of multiple vacuum absorbing panels in a dented shape disposed around a body in parallel in a circumferential direction, and also a vertical groove disposed in a laterally central area of each vacuum absorbing panel so that the vertical groove performs a function as a starting point for the deformation into a further dented state at the time of depressurization, wherein the vertical groove has a changing depth that gradually grows larger toward an upper end and a lower end, starting from a vertically central area of each vacuum absorbing panel.
