    摘要: A container and a method for making a container are provided. The method includes injection molding a preform having a body forming region, a neck forming region, and a dome forming region. After forming the preform, the preform is mounted in a mold having a surface, the mold surface having a neck forming surface to form a neck having a snap fit portion or a threaded portion. After mounting the preform, the preform is stretched against the mold surface to form an intermediate article having a dome portion connected to a neck portion of the container. Thereafter, the dome portion is severed from the neck portion to produce a wide mouth container, wherein the ratio of a wall thickness of the neck forming region of the preform to the wall thickness of the neck portion is ranges from 4.8 to 7.

    摘要: The invention concerns a preform for a plastic container in the form of a can intended particularly for pressurised beverages, and the preform holder in the container manufacturing process. The preform (10) consists of a body (1) with a neck (3) ended with a thin outer flange (4). A supporting flange (6) is formed on the inner wall of the neck (3a), while the outer surface of the neck (3b) is even. The preform holder comprises a body (11) provided with pockets (13). The pockets seat mobile-anchored clasps (14) which are clamped on the body (11) with an elastic clamping ring (15). The clasps (14) each ends with a tooth (16) which extends over the seat (17) where the thin outer flange (4) of the preform (10) rests. The inner side wall of the seat (17) has a groove (19) carved in it to accommodate the supporting flange (6) of the preform (10).
