摘要:
This invention relates to methods and apparatus for making coated articles with one or more layers by dip, spray or flow coating. In one aspect, this invention relates to an apparatus and method for making coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In preferred embodiments, the apparatus and method permit the coated container or preform to be made in an energy-efficient manner that reduces the danger of coating damage and thus increases the efficacy of the final container.
摘要:
Disclosed is a preferred apparatus and method of molding preforms having a crystalline or semi-crystalline neck finish. The apparatus is an injection mold for producing preforms, which are then molded into plastic bottles and containers, such as for containing beverages and the like.
摘要:
An extruded blow molded bottle comprises a neck portion and a body portion. The body portion comprises a first inner layer and a second layer. The first inner layer comprises a first material selected from a group consisting of polyester, phenoxy type thermoplastics, phenoxy-polyolefin thermoplastic blends, and combinations thereof. The second layer comprises a second material selected from a group consisting of virgin PET, recycled PET, PETG, foam, polypropylene, polyester, polyolefins, phenoxy type thermoplastic, phenoxy-polyolefin thermoplastic blends, regrind scrap materials, and combinations thereof. The second material is different from the first material.
摘要:
In preferred embodiments methods and apparatuses can produce articles that have formable material. The articles may be mono and multilayer. The articles can be formed by various methods.

摘要:
Disclosed is a preferred mold design for producing plastic, molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold includes a temperature control system for maintaining the preform mold at a desired temperature. The temperature control system can pass fluid through channels within the preform mold to cool plastic that is injected into the preform mold. In some arrangements, a mold comprises a neck finish mold, the neck finish mold configured to transfer heat away from the molding surface toward a channel conveying a working fluid. A heat transfer member may be at least partially positioned within the channel to transfer heat to the working fluid. In some embodiments, the mold comprises a high heat transfer material.
摘要:
Disclosed are plastic preforms and containers in which the materials in the neck, neck finish and/or neck cylinder are at least partially in the crystalline state and the body is primarily in the amorphous or semi-crystalline state. This structure in a preform enables the preform to be easily blow molded by virtue of the amorphous material in the body, while maintaining dimensional stability in hot-fill applications. In addition, the amorphous inner surface of the neck finish stabilizes the post mold dimensions allowing closer molding tolerances than other crystallizing processes. The crystallized outer surface of the preform supports the amorphous structure during high temperature filling of the container. Physical properties are also enhanced as a result of this unique crystalline/amorphous structure.
摘要:
Disclosed is a mold system which comprises a cube configured to rotate about an axis, a first cavity platen comprising at least one first cavity section, a second cavity platen comprising at least one second cavity section, a fluid channel being disposed within at least one of the mandrels and a hydraulic connection member configured to connect at least one of the fluid channels to an inlet and or outlet positioned outside the cube. The cube comprises at least two sides, each side comprising at least one mandrel. The hydraulic connection member is configured to deliver a volume cooling fluid from or to the fluid channels while the cube is rotating.
摘要:
Preferred embodiments relate to methods and apparatus for making articles made of polyester, preferably virgin polyethylene terephthalate (PET), having coated directly to at least one of the surfaces thereof one or more layers of recycled or post-consumer PET and one or more layers of a material with good gas-barrier characteristics, preferably silicon oxide. Preferably, the recycled PET layer comprises about 25% to about 50% of the entire material content. Preferably the articles take the form of preforms and the containers are blow-molded therefrom and the barrier layer is subsequently applied. The preferred barrier materials have a lower permeability to oxygen and carbon dioxide than PET. In addition, the neck of the preforms and bottles is at least partially in the crystalline state and the body is primarily in the amorphous or semi-crystalline state. This structure in a preform enables the preform to be easily blow molded by virtue of the amorphous material in the body, while being able to have dimensional stability in hot-fill applications.
