This relates to a container which is formed of a thermoplastic material, preferably PET, wherein the container wall and flanges have a high degree of orientation and the required strength characteristics utilizing a minimum of resin in the formation thereof. An intermediate article of manufacture is formed with this article having a generally bottle-like configuration. The intermediate article of manufacture, which is blow molded from a conventional preform configuration, includes a lower portion in the configuration of the desired container and an upper portion which is an accommodation portion. The accommodation portion is removed from the container and becomes scrap which is reground. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
