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.

The present invention relates to molded foam having no hollow space caused in a plate-shaped portion. The molded foam comprises a tube body and a plate-shaped portion joined to the outer side of the tube body. The expansion ratio of the molded foam is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body at the periphery of a point joined to the plate-shaped portion and the thickness B of the plate-shaped portion is less than 2.82.

Hollow part manufacturing machine includes at least one mold in which hollow parts can be manufactured by application of a pressurized medium, a valve unit, having at least two valves, wherein an inlet of a second valve is connected to a second pressure accumulator, which is pressurized under a second pressure, and an outlet of the second valve is connected to a blow nozzle via a channel. The inlet of a first valve is connected to a first pressure accumulator that is under a first pressure and the outlet of the first valve is also connected to the blow nozzle via a channel. During at least a part of the molding process, the blow nozzle seals the material to be molded, and/or the mold, relative to the environment.

An extrusion blow mold machine forming hollow containers. The machine has at least one pair of opposing half molds that combine to form a mold and define a mold cavity. Each of the half molds is positioned on a carrier plate and includes first, second, and third mold segments. The first and third mold segments can move with respect to each other and with respect to the second, fixed mold segment. A mechanical structure creates vertical movement of the first and third mold segments relative to the second mold segment as the mold opens horizontally, without the aid of any electrical, hydraulic, or pneumatic device. A closing unit engages the carrier plate to move the carrier plate and its respective half mold toward and away from the opposing half mold and its respective carrier plate, thereby closing and opening the mold.
