摘要:
A dimensionally-stable, injection-molded portion of a blow molded intermediate article is engaged by a conveyance mechanism of a trimmer to controllably drive the intermediate article within the trimmer to permit accurate and high speed severing of the injection molded portion and moil from a blown finish container body. An injection-molded, closed end preform is provided having a neck finish with an internal and/or external peripheral drive surface. The preform is utilized to form an intermediate article including a container body and moil. The injection-molded neck portion of the intermediate article remains substantially unchanged from its as-manufactured preform condition and provides a dimensionally stable surface for use in driving and rotating the intermediate article within the trimmer.

A bottle exhibiting thick walls, constant material thickness, a hemispherical-shaped base-forming portion and a polygonal-shaped flange. The thick walls increase the bottle's resistance to pressure, oxygen permeation and heat, over that of traditional bottles. The hemispherical-shaped base increases the bottle's resistance to pressure, over that of traditional bottles. The polygonal-shaped flange enables processing equipment, including bottle fillers and bottle cappers, to handle the bottle.

A container and a method of making a container are provided. In one example, the container includes a body having an upper portion, a sidewall portion and a base portion. The upper portion includes a blown finish defining a longitudinal axis and an opening into the container. A first portion defines a tamper evident (TE) band formed on the finish and defines a first diameter at an outermost surface. A second portion is formed on the finish, offset toward the base portion relative to the first portion, and defines a second diameter. The second diameter is less than the first diameter. A transition portion is formed between the first and second portions. The transition portion defines an annular taper from the first portion to the second portion.

A one-piece plastic container includes a body defining a longitudinal axis. The body includes an upper portion, a sidewall portion and a base portion. The upper portion defines an opening into the container. The sidewall portion may be integrally formed with and extend from the upper portion to the base portion. The base portion closes off an end of the container. The opening defines a radial sidewall and a generally linear sidewall. The generally linear sidewall may be defined by an inset portion formed on the upper portion.

A finish on a hollow plastic preform or container includes a neck that is at least partially of crystallizable polymer construction and is at least partially crystallized, and a finish ring externally secured over the neck. The neck preferably is of molded plastic construction, and preferably is stretched subsequent to molding but prior to external securement of the finish ring. In the preferred embodiments of the invention, the preform or container has an integral body, and the neck is integrally molded with the body. The finish ring preferably has at least one external thread for securement of a closure to the container after molding.

The invention relates to a container which is formed at the upper portion of the main body with the foldable portion having folding lines for easily folding the foldable portion. Processes for forming the container include a first step for forming a perform by injection molding and a second step for forming the finished product having the foldable portion by blow molding.
摘要:
Processes for obtaining new composite preforms (26) suitable for blow-molding made of at least two different materials (4, 22), preforms obtained thereby, and articles obtained by blow-molding of these preforms. The processes employ the injection-molding of two (or more) plastic materials to form preforms that can be blow-molded into articles. In a preferred embodiment, the two materials have different colors and the resulting articles show a multi-colored effect. The two materials are not laminated over each other.

A method of making a wide mouth, blow molded PET plastic container having an externally threaded neck, the diameter and wall thickness of the neck and threads have a critical relationship to the diameter and wall thickness of the preform used to blow the intermediate article of which the container is a part. A PET plastic container having a threaded neck with a wall thickness of within the range of 0.032 to 0.038 inches.
摘要:
A preform assembly for blow molding a container includes a molded plastic preform having a body and a neck with an external surface. The neck includes a plurality of spaced lands molded integrally with the neck and the body and defining the external surface of the neck, and a plurality of open spaces between the lands. A plastic finish ring is molded separately from the preform and is externally secured over the lands. The open spaces between the lands reduce heat transfer between the preform neck and the finish ring. In two exemplary embodiments of the invention, the lands include either spaced axial ribs or spaced circumferential ribs on the preform neck, and the open spaces include either spaced axial channels or spaced circumferential channels between the ribs.
