ABSTRACT:
An integral hinged blow molded container having a single wall is produced by inflating a parison within a mold having a hinge forming area with a draw ratio of greater than 1 whereby the parison is reduced to thickness within the hinge forming area relative to the adjacent area. The thus formed parison is severed about a circumference adjacent the formed hinge to create a top portion and a bottom portion openable and closable about the hinge.
