ABSTRACT:
One of the main objectives of the present invention is to provide a frosted bottle made of a saturated polyester.
The bottle according to the present invention is made from a cylindrical material prepared by injection molding and has a bottom wall and a transparent upper portion in the vicinity of the opening thereof. The peripheral outer surface of the cylindrical material is heated to allow the outer surface to become milky white, and is then put into a mold for blow molding to inflate the trunk and bottom walls other than the neck portion thereby for forming a bottle. The bottles according to the present invention are, therefore, characterized by having walls which are composed of inner transparent portions and opaque outer peripheral portions of milky white color, when viewed in cross section.
