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.

A method of simultaneously forming two blow molded plastic containers, said method comprising the steps of providing a tubular preform having an open end and a closed end, placing said preform in a blow mold cavity of greater length than said preform, introducing a blowing gas into said preform through said preform open end and blow molding said preform with the stretching of said preform both axially and radially to an intermediate shape defining at least two containers each having an open end defined by a radially outwardly directed biaxially oriented seaming flange with said flanges being generally in opposed relation, said preform open end remaining constant, and cutting said intermediate shape to separate and define said two containers. An intermediate article of manufacture comprising an integral blow molded hollow plastic member having an open neck portion and at least two separate containers integrally joined together, and each of said containers has an open end defined by a biaxially oriented seaming flange. A blow molded plastic container comprising a biaxially oriented tubular body having one end open and a second end defined by a shoulder joined to a tubular neck, and a metal bottom seamed to said body enclosing said one open end, said tubular neck being of an injection molded construction.
