发明名称 Blow molding a container having three handles
摘要 A container such as a jerry can can be produced with one or more handles molded with the blow molded body of the container. This invention eliminates the need for separate injection molded inserts. A first pair of molds, and a second pair of molds having a lower and upper section, are used in the apparatus to close a top portion and a bottom and/or draped portions of a standard parison.
