Blown plastic container having an integral single thickness skirt of bi-axially oriented PET

Abstract

A blown bottle useful for containing a carbonated beverage bottle is formed with an annular single thickness depending skirt formed integrally with the bottle bottom providing a self-standing support for the bottle. A parison or preform for the blow molding of bottle is formed with a rounded, closed bottom portion and a cylindrical and integral annular single thickness skirt portion, for use in blow molding of a carbonated beverage bottle having an integral skirt for free-standing. The method of making a self-standing bottle, such as for carbonated beverages and the like, includes the forming of a bottle preform with an annular depending skirt which surrounds a closed bottom portion, and blowing the preform while gripping the skirt portion and spreading it outwardly and downwardly in relation to the orientation of the bottle to form an annular support skirt or platform in the blown bottle.
