Abstract
This relates to the forming of a blow molded polyester container wherein a bottle having a conventional upper neck portion and an intermediate body is provided with a lower portion which includes an annular seaming flange which is integrally connected to the lower end of the body and wherein, with the exception of the seaming flange, the lower portion is removed and the bottle is closed by a separately formed bottom double seamed to the lower end of the body utilizing the annular seaming flange. During the interim between the removal of the bottle lower portion and the application of a separate bottom, the bottle is fully open so as to be readily commercially interiorly coated with a barrier coating. The separately formed bottom may be readily formed of metal and may be so constructed as to provide a large diameter base for supporting the bottle in upstanding position. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
