Abstract
A process and apparatus for forming a leakproof plastic container by completely ejecting from a mold and then transferring to a cap closing station. The process includes the steps of injecting a molten plastic material into a mold cavity and then opening the mold and ejecting the body and cap completely from the mold. Subsequently, the body and cap are gravity fed to a collection device and then transferred to a cap closing station. In the cap closing station, the body and cap are sealed before the material is fully set to form a leakproof seal.
