Abstract
A synthetic resin container according to the invention has a craze pattern on the outer surface of its body. The container comprises an inner layer that comes into direct contact with content during its storage, an outer layer laid over the inner layer, and a translucent protective layer laid over the outer layer. The outer layer carries a craze pattern that has been obtained by applying a solvent to a preform or parison of the container after blow molding thereof. The protective layer covers and protects that portion of the outer layer, which carries the craze pattern, and preserves its visibility from outside.
