A plastic container is provided that includes a lower supporting base portion; a sidewall portion extending upwardly from the base portion; a neck portion extending upwardly from the sidewall portion; and a closure. The neck portion includes a support flange having an upper and lower surface, threads, a tamper-evident formation, and a dispensing opening at the top of the neck portion. In an embodiment, the weight of the neck portion is 3.0 grams or less; and the vertical distance from the top of the dispensing opening to the lower surface of the support flange, including the threads and the tamper-evident formation, is 0.580 inches or less. A preform and method for making a container are also disclosed.

A plastic preform is provided that includes a closed bottom portion; a lower portion extending upwardly from the bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a support flange having an upper and lower surface, threads, a tamper-evident formation, and a dispensing opening at the top of the neck portion. In an embodiment, the weight of the neck portion is 3.0 grams or less; and the vertical distance from the top of the dispensing opening to the lower surface of the support flange, including the threads and the tamper-evident formation, is 0.580 inches or less. A container and method for making a container are also disclosed.

A preform is disclosed for the production of plastic containers, for example plastic bottles, in a stretch-blow-molding method. The preform can include an elongated preform body having a closed longitudinal end and which connects on an opposite longitudinal end to a neck section having a pour opening, the neck section having an outside wall with a fastening means. A rotating flange at a transition from the preform body to the neck section, wherein at least a portion of the rotating flange is annular and radially extends above an outside wall of the preform body. A peripheral annular groove can extend obliquely from a base of the annular groove to the outside wall of the neck section forming a circumferential inner collar, and wherein the inner collar the direction of the preform body, extends axially above the annular groove and extends into an inside wall of the preform body.

A container obtained by blow-moulding a rolled tube. The container includes a body extending, according to a longitudinal axis, between a bottom and a neck made integrally in one-piece with the body. The body has, along a height according to the longitudinal axis, a wall having a thickness between 0.05 mm and 0.4 mm. The neck has, along the height according to the longitudinal axis, a wall having a thickness between 0.4 mm and 0.8 mm.

Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.

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.
