Abstract
Apparatus is disclosed herein for blow forming a double-walled container or body using either injection or extrusion molding techniques. A mold is provided having a movable sleeve which separates and defines a pair of coaxial wall cavities in parallel relation for receiving a parison during injection molding. A mold is further provided for movably positioning its halves about a pair of coaxial cylindrical parisons so as to close the opposite ends of a predetermined length, this latter procedure being an extrusion molding technique.
