Abstract
This relates to blow molded containers, and particularly to the formation of blow molded containers formed of a plastic material which is subjectable to a high degree of biaxial orientation for maximum strength. Two containers are formed in each blow molding operation with each container having throughout the stress areas thereof a high degree of biaxial orientation. A container may be in the form of a bottle having an as formed open bottom which is closed by a metal end unit seamed in place. Other containers will have open mouths closed by conventional closures including metal end units which are seamed to the container body or by closure caps which may be releasably interlocked with the neck finish of the container in several known modes. In every instance the containers are formed with a minimum of scrap. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
