Abstract
Preforms or parisons are blow molded from synthetic resin into hollow articles including a neck region and a body area, the hollow articles having hooks and recessed areas formed into their outside walls. Flexible strings are molded below the neck region of varying thickness in the longitudinal direction to achieve molecular orientation of the synthetic resin. The flexible strings are looped around the hooks or lifted above the neck finishes to form flexible handle containers. Rigid handles or combined flexible string and rigid handle portions are incorporated into the hollow articles to form rigid handle containers.
