ABSTRACT:
A plastic container having a bail handle on one side, blown as one-piece with the container, is formed by injection molding a parison with a thickened portion then blow molding in a cavity having a portion into which the thickened portion of the parison is displaced to form a handle portion. A shearing operation is then performed on the partially blown container. In this operation part of the handle portion is compressed to a flat condition and displaced from the container between the body of the container and the part of the handle portion that will constitute the actual handle of the final container. The container is then blown to its final size, preferably in a second blowing mold. The apparatus used to make the container is also novel.
