Abstract
An apparatus for forming a container generally comprises a first mold part having an injection mold portion and a blow mold portion and a second mold part having a core pin. The core pin is configured to cooperate with the injection mold portion in a first position to define an injection mold cavity for forming a preform and an integral cap. The core pin is also configured to cooperate with the blow mold portion in a second position to define a blow mold cavity for forming a receptacle from the preform. The cap may be closed at the blow mold portion to seal the receptacle. One or more threads may be formed on a neck of the container.
