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.

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 nonstrain 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： A transparent oxygen-scavenging article for packaging oxygen-sensitive products, such as beer, juice, ketchup, etc. The oxygen-scavenging article includes a biaxially-oriented aromatic polyester polymers such as polyethylene terephthalate (PET) or polyethylene naphthalate (PEN), and an oxygen-scavenging aromatic ester polymer compatible with the polyester polymer. The oxygen-scavenging polymer includes aromatic groups and alpha-hydrogen carbonyl groups of formula (I). Examples are polyesters from succinic, glutaric, adipic or suberic acid with hydroquinone, bisphenol A, styrene oxide or distyrene glycol or an aliphatic dicarboxylic acid containing copolyethylene naphthalate. Both polymers could form a copolymer, a blend or preferably different layers of the article. The oxygen-scavenging polymer may be incorporated into a barrier package at a competitive price, and provide the desired properties of transparency, thermal resistance, and pressurized strength.

摘要： A method of reducing uncontrolled flow of a molten polymer during the packing and cooling stage of an injection molding cycle. A plurality of polymers are injected between a mold cavity and core for making a multilayer plastic article such as a preform, having an exterior layer of a first polymer and an interior layer of a second polymer. In a tapered region of the mold, a minimum width of the tapered region is selected to prevent the second polymer from developing an enhanced leading/trailing edge effect which causes the second polymer to reverse flow during the packing and cooling stage. The method is particularly useful for making preforms for blow molded containers, such as a ketchup container, having a relatively long and thin neck profile. In addition, the method maintains the interior (barrier) layer a minimum distance from the top sealing surface of the preform, in order to prevent defective heat-bonded seals.
摘要翻译：在注射成型循环的包装和冷却阶段减少熔融聚合物的不受控流动的方法。多个聚合物被注入模腔和芯之间，用于制造多层塑料制品例如预制件，其具有第一聚合物的外层和第二聚合物的内层。在模具的锥形区域中，选择锥形区域的最小宽度以防止第二聚合物形成增强的前后效应，这导致第二聚合物在包装和冷却阶段期间逆流。该方法特别可用于制备具有相对较长和细颈部轮廓的吹塑容器（例如番茄酱容器）的预成型件。此外，该方法将内部（阻挡层）保持与预成型件的顶部密封表面的最小距离，以防止有缺陷的热粘合密封。

The panel section (136) has a substantially cylindrical circumference with a plurality of vacuum panels (140) symmetrically disposed about the panel circumference, post walls (162) between the vacuum panels, and land areas (138, 142) above and below the vacuum panels. The ratio of vacuum panel height D to panel diameter C is on the order of 0.85 to 1.05. Longitudinal post ribs (164) are provided in the post walls. The land areas above and below the vacuum panels are of a height E greater than on the order of 0.45 inch, and the ratio of the land area height E to panel diameter C is on the order of greater than 0.1. Circumferential hoop ribs (137, 134) are provided in the land areas to prevent ovalization and hoop collapse.

摘要： A method of making a blow-molded container (1) from a strain-hardenable polymer, the container (1) having deep recesses (20A, 20B) for secure "post-mold" attachment of a handle (40). The container is formed in a modified blow mold (60) having retractable blades (70). The blades (70) are partially extended for blow molding partial recesses, and then further extended for mechanically forming the deep handle recesses. The mechanical forming operation overcomes the stretch limits imposed by strain-hardening of the plastic material during blow molding, and the "post-mold" attachment of the handle (40) provides a reduced cycle time and lower level of defects compared to the known "in-mold" handle forming operations.

摘要： The present invention relates to a blow-molded, multilayer container, a preform, and methods of making them. The majority of prior art devices do not have a unitary molded structure with separable inner and outer layers and vents, thus complicating manufacturee. The present invention overcomes this deficiency by blow molding a multilayer preform and molding apertures into the preform. The container (50) has an integral body with an inner layer (58) which readily separates from an outer layer (59) and collapses to dispense a product from the container by application of positive or negative pressure. The container is formed by blow-molding a multilayer preform (20), and a bottom aperture (21) is formed in the container for injecting air to separate the inner layer from the outer layer. In case of vacuum dispensing, air vent holes (558) are preferably formed at the points of maximum deformation.

摘要： A multilayer plastic container having enhanced strength for high temperature and pressure applications such as the pasteurization of carbonated juice drinks. The container is commercially cost-effective in comparison to prior art pasteurizable glass containers, and provides all of the advantages of plastic over glass, i.e., lightweight, shatter-resistant, etc. In a particular embodiment, the multilayer container includes inner and outer layers of a relatively high IV virgin PET, e.g., 0.85-0.90 dl/g, and a core layer of post-consumer PET having a substantially lower IV. The container has a relatively tall and slender profile, with high orientation levels in the panel and shoulder, and an oriented thick-walled base with feet. The base preferably has a high profile and angled foot pads which are allowed to move outwardly under creep. According to a method of making a multilayer preform for such container, an enhanced injection rate and mold pressure are utilized to enhance interlayer bonding and prevent separation of the layers in spite of their substantial differences in IV.

摘要： A pasteurizable plastic container having movable panels to alleviate internal pressure changes during pasteurization in order to avoid uncontrolled permanent deformation of the container body. As molded, each panel has a shallow recessed central wall which during the increased temperature and pressurization of pasteurization, moves outwardly to alleviate at least part of the internal pressure. During cooling, the panels move back inwardly to alleviate at least part of the negative pressure. The container may further include hoop ribs in the land areas above and below the panels, an axially elongatable hoop rib in an upper shoulder section, and an angled heel portion adjacent the standing ring. These additional elements further restrict uncontrolled bulging of the post walls, which would lead to improper label application and/or excessive volume change.
