Abstract
Abstract This invention relates to blow molding hollow articles such as bottles of oriented plastic material and particularly to forming a well-defined peripheral projection means, such as a cap-receiving screw thread on the periphery of the bottle at the neck, and comprises shifting longitudinally that portion of the screw thread of the bottle after the bottle has been blown and while it is still under blowing pressure.
