摘要： A method for post-mold attachment of a handle to a strain-oriented plastic container body. The method utilizes thermal shrinkage of the oriented container body to engage the handle; for example, a highly-oriented recess is molded in the container body and then shrunk to engage a complimentary-shaped lug on the handle. The method is useful for both hot-fillable and pasteurizable containers, and is particularly useful for making larger-sized containers, wherein the weight of the product and size of the container make handling and pouring difficult.

摘要： A multilayer preform and container, and method of forming the same, having at least one layer including polyethylene naphthalate (PEN) to provide enhanced oxygen barrier performance and thermal stability. The PEN layer may be a homopolymer, copolymer, or blend of PEN. In a first high-PEN embodiment, the exterior layer contains on the order of 80-100% PEN and 0-20% PET by total weight of the layer, and a core layer of a non-strain hardenable polyester such as PETG. In a second low-PEN embodiment, the exterior layer includes a strain hardenable low-PEN copolymer or blend including on the order of 1-20% PEN and 80-99% PET, and the core layer is a strain-hardenable polyester such as a low-copolymer PET. In a third mid-range PEN embodiment, the exterior wall includes a substantially amorphous PEN copolymer or blend containing on the order of 20-80% PEN and 80-20% of another polyester such as PET, and a strain-hardened core layer of polyester such as a low-copolymer PET. To further enhance the oxygen barrier and thermal stability properties, the core layer may further include a copolymer or blend of PEN. Alternatively, PEN may be provided in an interior layer only.

摘要： Method of making multilayer preforms which resist delamination and in a reduced cycle time. A first array of preforms are molded onto a first array of cores in an associated array of mold cavities, the cores and preforms are removed from the mold cavities as soon as possible without significant physical preform deformation, and the preforms are then cooled on the cores while a second array of cores is positioned in the mold cavities. Cooling on the cores prevents delamination of the preform layers and reduces the in-mold cooling time. Providing multiple sets of cores on a rotating turret further reduces the cycle time compared to the prior art use of robotic cooling tubes.

摘要： A plastic preform from which a plastic container is blow molded. The preform replaces a three layer preform by providing a preform which is of a five layer construction in the base forming portion thereof and wherein a secondary material which forms the core layer of the three layer preform construction is divided into an inner intermediate layer and an outer intermediate layer by a third injection of material. The third injected material is preferably the same material as the primary material which is first injected. This results in the reduction of the cost of the preform and also provides remaining in the injection nozzle a quantity of the last injected material which is the same as the first injected material for the following preform in the same preform injection mold cavity.

摘要： This relates to blow molded plastic containers wherein at least the body of such containers is of a laminated construction including, for example, a barrier layer which in the case of the container receiving carbonated products would be a gas barrier layer. It has been found that delamination does occur and this is now solved by selectively providing the container body with minute vent openings which do not extend entirely through the container body, but into that area where delamination occurs and there is an accumulation of a permeant, such as CO.sub.2. The minute vents may be formed in the exterior wall of the container either by way of piercing pins or by utilizing a laser. In the case of the piercing pins, there are incorporated in the blow mold for blow molding the container from a preform and are generally placed along the parting lines of the blow mold and also in central parts of the wall. The construction and operation of the piercing pins may be provided in several forms.
