Abstract

A hot-fill type plastic bottle having a body, wherein said body has a octagonal cross-sectional shape, each of corners of the octagon is formed with a ridge wall, connecting walls are provided at both lateral sides of each of the ridge walls to form a pillar, a pressure reduction absorbing portion is formed between any two adjacently located ones of the ridge walls, and two connecting walls of one of the pillars form an angle between 60 and 115°. The rigidity of the pillar is raised. The bottle shows a pressure reduction absorbing effect similar to that of a conventional hexahedral bottle. In addition, the wide area of the shrink-wrap type label can be seen at a glance.
