A PET bottle forming machine used to mold clear plastic bottles of the type now widely used for mayonaise jars, cosmetic jars, perfume jars and the like, is modified to reduce the potential damage to such jars or containers at the time they are released from the machine. The machine includes an ejector pad, which enters into the open end of the container to center the container at the time a lip spreader operates to part the lip forming portion to release the container. The ejector pad is mounted on the end of a hollow rod, which extends through the pad. When the ejector pad is inserted into the open end of the container at the time of release, a vacuum is applied through the hollow rod to cause the container to be secured to the ejector pad. The hollow rod, with the ejector pad and container releaseably secured to it, then is lowered to place the bottom of the container on a support surface, at which time the vacuum is removed to release the container from the ejector pad. The support rod and ejector pad then are raised to an initial starting position for a repeat of the cycle.
