Abstract
A method of making a container via a simultaneous filling and forming of the container with a liquid product is disclosed. The method comprises the steps of extruding a parison (12, 2), capturing a portion of the parison (12, 2) within a mold (15), and inflating the captured portion of the parison (12, 2) against the mold (15). The captured portion of the parison (12, 2) is inflated against the mold (15) by introducing the liquid product into an interior of the captured portion of the parison (12, 2), wherein the liquid product forms an end product to be sealed within the resultant container.
