Blowing and Filling Containers

摘要

U.S. Patent 9,216,537 (December 22, 2015), "Compensation for Hydrapak Machine using Isolator Cylinder," Brad Wilson, Kirk Edward Maki, and George David Lisch (Discma AG, Hunenberg, Switzerland). As a result of environmental and other concerns, lightweight polyethylene terephthalate (PET) containers are now being used more than ever to package numerous commodities previously supplied in glass containers. Traditionally, blow molding and container filling were developed as two independent processes. In many cases these steps are carried out by different companies. Attempts are being made to combine blowing and filling in one step for efficiency and cost reduction.
