A method comprises the following steps: providing a pre-processed element made of at least one polymeric material, introducing the pre-processed element in a female mould part having a forming cavity, shaping the pre-processed element between the female mould part and a male mould part, the female mould part and the male mould part being movable relative to one another along a moulding direction so as to form a concave object from the pre-processed element.

The forming cavity has a transversal dimension measured transversely relative to the moulding direction, the forming cavity further having a transition zone in which the transversal dimension passes from a larger value to a smaller value, the forming cavity further having a bottom.

During the introducing step, the pre-processed element is placed on the transition zone, so that the pre-processed element rests on the transition zone at a distance from the bottom of the forming cavity.

The invention relates to a plastic container which is stretch blow-molded from a preform and which comprises a container body having a container neck attached thereto, on which container neck there is provided an outlet opening, wherein the container body has a second opening closed by a weld seam. The container is made from a copolyester. The wall of the stretched container body has a stretching ratio relative to the wall of the unstretched container neck in the region of the at least one weld seam of more than 6:1. After the welding, the stretched container body has a density increase relative to the unstretched container neck in the region of the at least one weld seam of less than 0.06 g/cm.sup.3.

Provided is a stretched body having a high barrier property under high humidity, a PET bottle, and a method for producing a container. The stretched body of a composition containing a semi-aromatic polyamide resin and plate-shaped talc having an aspect ratio of more than 18, a content of the plate-shaped talc having an aspect ratio of more than 18 in the composition is from 3.0 to 55.0 mass % when a total content of the semi-aromatic polyamide resin and the plate-shaped talc having an aspect ratio of more than 18 is 100 mass %.

The invention relates to a preform (1) for a container (2) made of plastic, wherein the preform (1) comprises a body part (3) comprising a wall having a thickness (e1) which extends along a longitudinal axis (X) and which is connected, via a periphery (8), to a closed bottom part (5) which has an apex (10). According to the invention, the bottom part (5) has ribs (11) which each extend from the apex (10) of the bottom part (5) to the periphery (8) so as to form a star, and a substantially triangular zone (12) arranged between two adjacent ribs (11) and a portion (8a) of the periphery (8) has a thickness (e3) which is less than the thickness (e1).

A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.

The disclosure provides a preform layered body and a layered container produced by biaxial stretch-blow forming of the layered body. In this preform layered body, an RFID tag has been inserted between an inner-layer-use mouth part and an outer-layer-use mouth part that are to remain unaltered, with no biaxial stretch-blow forming performed thereon, as a container mouth part for a layered container. Since the container mouth part does not become exposed to the high temperature and high pressure for stretch-blow forming purposes, abuses to the RFID tag, such as damage, breakage, and deformation, which arise from the heating, pressurization, and stretching during the stretch-blow forming, can be avoided reliably. In addition, labor-saving and counterfeit prevention effect can be anticipated by causing the RFID tag to hold product information.
