Abstract
A biaxially oriented bottle of saturated polyester resin has a disadvantage that the mouth or the part extending from the neck to the shoulder, which is not oriented or is oriented only a little, is much poorer in durability and resistance to the content liquid than the body which is molded under sufficient orientation. Such a disadvantage has been surmounted in this invention by covering the inside of the mouth or the part extending from the neck to the shoulder, which is in direct contact with the content liquid, with a layer which is durable and resistant to the content liquid.
