A container including a longitudinal overlapping seam extending from an end seam and a mold part line extending from the closed end of the container to the open end of the container. The container wall consists of a one-piece thermoplastic substrate.

A package including: a container; and a plug seal closure operatively engaged with an open end of the container; wherein the container has; a closed end opposing the open end; a container wall extending longitudinally between the closed end and the open end about a longitudinal axis; an end seam extending at least partially across the closed end; and a longitudinal overlapping seam extending from the end seam, a portion of the overlapping seam extending longitudinally along the container wall between the closed end and the open end; wherein the open end is narrower than at least a portion of the container away from the open end of the container; and wherein the closed end and the container wall consist of a one-piece thermoplastic substrate.

An injection head for a container-fabricating apparatus. The injection head includes a first nozzle establishing fluid communication between an injection liquid source and a preform cavity of a substantially tubular preform. The first nozzle is configured to mate with a mouth of the preform. An annular mouth seal, provided in the first nozzle, creates a seal with the mouth of the preform when disposed in contact therewith.

A threadless plastic blow molding device includes a main molding-base, a bottom molding-base, and a blow molding-base. The main molding-base has two mating portions each defines a recessed cavity. The recessed cavities correspond to each other when the mating portions are mated. The bottom molding-base and the blow molding-base are respectively assembled to two ends of the main molding-base. The blow molding-base has a gas blowing portion. The main molding-base, the bottom molding-base, and the blow molding-base collectively define a forming space for forming a blank. The blow molding-base has an expanded portion extended toward the mating portions. Each of the mating portions has a recessed section corresponding to the expanded portion. Accordingly, the blank can be positioned in the molding device.

A mould system for moulding a receptacle is described. The mould system comprises a mould comprising a mould cavity and an opening, and a mandrel system comprising a reference point, a mandrel and an expandable member. The mandrel is at least partially located, or at least partially locatable, inside the expandable member and comprises one or more holes through which a fluid is flowable in use from an interior of the mandrel to an exterior of the mandrel to expand the expandable member. When the mandrel is at least partially located inside the expandable member, the mandrel system is positionable relative to the mould such that the reference point is at a fixed position relative to the mould and the mandrel, and the expandable member extend into the mould cavity through the opening such that there is a clearance between the expandable member and a base of the mould cavity opposite the opening. The expandable member and at least a part of the mandrel are moveable relative to the reference point to vary the clearance.
