Abstract: A color coated article is formed by applying a color coated material to an injection mold having mold halves, a mold cavity edge and a mold cavity therein for the formation of an injection molded article, and injecting molten plastic into the mold cavity to form a laminated article with the color coated material bonded to the injected plastic. The process uses a color coated blank having a roughened surface, said blank adapted to be placed into at least one mold half and transferring the blank into registry with at least one of the mold halves. The molten plastic is injected against the roughened surface of the blank to enhance bonding of the blank to the injected plastic.

Abstract: A multilayered container and a process for forming the same are disclosed. The container includes a support wall formed from a plastic having an undesirable substance therein and polymerized to a level less than that necessary to prevent the undesirable substance from migrating from the plastic into the contents when the contents are in contact with the support wall. A protective wall is provided adjacent the support wall and adapted to be positioned between the support wall and the contents. The protective wall is formed from a material which limits the migration of undesirable substance from the support wall into the contents.

Abstract: A process for forming a footed plastic container, comprising the steps of providing a preform having a neck portion with an open top end, an elongated cylindrical body portion with inner and outer walls and a lower end, wherein the lower end includes a plurality of thickened portions; providing a blow mold in the shape of a footed container having an elongated sidewall, wherein the blow mold includes a plurality of separate container foot forming cavities; inserting the preform into the blow mold; placing each of the thickened portions in a predetermined position relative to the foot forming cavities; and stretch blow molding the preform, and displacing material from each of the thickened portions into one of the foot forming cavities to form the plastic container.

Abstract: The closure assembly includes: a container having an access opening; an inner closure with a rim attached to the container, a central portion covering the access opening, a weakened portion in the central portion, and a separably interlocking portion in the central portion, as a threaded portion; a removable closure covering the inner closure and separably interlocking the inner closure; whereby twisting the removable closure as by threading action on the inner closure breaks the inner closure at the weakened portion and opens the container. Also discloses a method for opening a closure assembly.

Abstract: A method of preparing filled plastic containers by preparing a formed plastic precursor by thermoforming, pressure molding, or tabletting in a precursor preparation station, heating the plastic precursor in a heating station to a compression molding temperature, preparing a plastic preform by compression molding the heat plastic precursor in a preform production station, blow molding the preform into the configuration of a final container in a blow molding station, and filling the blow molded container in a filling station, wherein the preform preparation, blow molding and filling are performed sequentially in physically proximate operations.

Abstract: Process for forming a multilayered plastic article and multilayered plastic preform and container, wherein a polyepoxide or a liquid crystal polymer in the liquid form is applied to a substrate in a thickness which varies over the extent of the substrate to form a multilayered substrate, forming a tubular liner from said multilayered substrate, and coating the tubular liner with an outer layer.

Abstract: A preform, a process for forming the preform and a container formed from the preform are disclosed. The preform comprises a tubular body portion having an open end and a closed end. At a location near the open end, a flange extends outwardly from the tubular body portion. A closure retaining element is provided for engaging a closure. The closure retaining element is formed separately from the tubular body portion and includes a manner for attachment to the tubular body portion. The closure retaining element is attached to the tubular body portion adjacent the flange via the manner for attachment.

Abstract: A method for producing a partitioned container of the present invention includes the steps of providing a preform having an interior surface; separately forming an inner wall for insertion into the preform; inserting the inner wall into the preform; preparing for molding and molding the preform and inner wall into the partitioned container; and activating a manner for securing the inner wall to the interior surface of the preform during the step of preparing. A system for forming a partitioned container in accordance with the present invention includes a preform including an interior surface surrounding a cavity; an inner wall formed separately from the preform, the inner wall including a manner for securing to the preform upon the application of heat thereto, and a molding device for molding the preform into the container.
