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.

A multilayer container having a polyester layer comprising a thermoplastic polyester resin (X) and a polyamide layer comprising a polyamide resin (Y), wherein the polyester layer is an innermost layer and the polyamide layer is an interlayer, and the polyamide resin (Y) comprises a polyamide resin (Y-1) comprising a structural unit derived from a diamine and a structural unit derived from a dicarboxylic acid, 70 mol % or more of the structural unit derived from a diamine being a structural unit derived from xylylenediamine; and 70 mol % or more of the structural unit derived from a dicarboxylic acid being a structural unit derived from an α,ω-linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms, and wherein a stretching ratio in a transverse direction (TD) is 2.2 times or more, and a stretching ratio in a machine direction (MD) to the stretching ratio in the transverse direction (TD) (MD/TD) is 0.6 or more and less than 1.0.

A polymer composition comprising two or more polymers may be used in preforms and containers for hot-fill beverages to increase recycled content, shelf-life of the contents, and stiffness of the container. One polymer may be polyethylene terephthalate and the second polymer may be either polyethylene furanoate or polyethylene naphthalate. The polymers may be blended to form a cube blend. A reheat agent may be used in the polymer composition. Methods of making the preform and the bottle are also disclosed. The polymer compositions may be made of increased recycled content without sacrificing transparency of the material and may be used to make clear preforms and bottles.

A method and a device for producing containers formed by pneumatic or hydraulic pressure (i.e. blowing pressure or the pressure of a fluid to be filled) from preforms with a blow mold are provided. The blow mold has a bottom mold with an axially displaceable bottom die, wherein for exerting a counterforce on the bottom die is configured to bias the bottom die into an extended position being arranged in the interior of the blow mold and being extended from the bottom mold, wherein the stretching rod is configured to displace the bottom die against the counterforce into a retracted position substantially being arranged in the bottom mold. The counterforce clamps the preform stretched by the stretching rod between the tip of the stretching rod and the bottom die so that the container being formed is always kept centered.

A method of operating a container treatment system, wherein a plurality of parameters of the container treatment system, which are characteristic for the treatment of containers in the container treatment system, are variable and wherein the parameters are each linked to at least one value characteristic of the containers to be treated, wherein for each parameter a plurality of reference parameter values are stored in a storage device, wherein at least one characteristic value of the containers to be treated is entered at a user interface and, on the basis of this entry and the stored reference parameter values, a combination of parameter values for the parameters is calculated.

A synthetic resin container that is formed in a bottle shape having a mouth and a trunk and that is provided in the trunk with at least one reduced pressure absorbing panel. The trunk has a density of 1.3695 g/cm.sup.3 or more, and a ratio of a crystal orientation in a transverse direction with respect to a total value of a crystal orientation in a machine direction and the crystal orientation in the transverse direction in the trunk is less than 44%.

Preform assembly for blow moulding a container, comprising at least a first and a second perform, wherein the first perform is positioned inside the second perform before blow moulding the performs into the container, wherein each perform has a body forming portion having a wall thickness of less than about 8 millimetres, preferably less than about 6 mm.
