Abstract
There is provided an improvement in an injection molding apparatus for a container, where the apparatus includes a core defining the interior of the container and first means within the core for initiating ejection of a molded container from the core. The improvement consists of second means adjacent the rim of the molded container for blowing a gaseous material toward the container rim, thereby completing ejection by urging the container away from the core.
