ABSTRACT:
This invention provides a synthetic resin thin-walled bottle, a tubular intermediate therefor and a method of producing a thin-walled bottle. The thin-walled bottle has ribs at least at its bottom portion, and the bottle bottom is raised up frusto-conically or has an undulatory shape. The tubular intermediate is first formed with ribs which become thin-walled protuberant ribs after blow molding. The thin-walled bottle is produced by blow-molding the ribbed tubular intermediate.
