Title:
BOTTLE-SHAPED RESIN CONTAINER
Document Type and Number:
WIPO Patent Application WO/2015/025532
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a bottle-shaped resin container with which it is easy to determine whether or not the seal has been broken and the cap ring can be easily removed. A bottle-shaped resin container (1) with a bottle body (3) and a cap (5), the container being configured to make it possible to determine whether the seal has been broken by: the container having a long, tall cylindrical section (70) between a neck ring (34) and a flange (36) that connects the neck ring and the flange; and when the cap body (52) is rotated in the unscrewing direction, bridges (56) being broken and the cap ring (54) separating from the cap body (52) and falling by its own weight so that the lower surface thereof contacts the flange (36) and remains above the flange (36), exposing the side surface of the long, tall cylindrical section (70) between the upper surface of the cap ring (54) and the lower surface of the neck ring (34). Since the side surface of the long, tall cylindrical section (70) is a straight line when viewed from the front, it is possible to determine the taper angle definitively and said taper angle is 60-80 degrees.
