摘要： A method of feeding a composite molten resin capable of easily forming amulti-kind-multi-layer preform. An apparatus for feeding the composite molten resin has a nozzle portion which includes an outer discharge port in which an outermost annular flow path through which a main layer-forming molten resin flows, meets an outer annular flow path through which a sub-layer-forming molten resin flows inside of the outermost annular flow path; and an inner discharge port in which a shell layer-forming molten resin annularly flowing inside of the outer conflux path, meets the core layer-forming molten resin flowing inside the shell layer; the outer discharge port and the inner discharge port being arranged in this order from the downstream toward the upstream in a direction in which the molten resins flow; wherein provision is made of a shaft-like opening/closing valve for opening and closing the inner discharge port, and a gear pump for intermittently discharging the sub-layer-forming molten resin.

摘要： The invention aims at solving problems caused by the incorporation of a gas barrier layer, that is, lowering in the dimensional accuracy of the mouth portion by thermal crystallization and delamination of the bottom, independent of the dislocation of a gas barrier layer occurring in the coinjection of a PET resin layer and the gas barrier layer. A biaxially oriented blow-molded bottle in which a gas barrier layer (3) is incorporated in a PET resin layer (2) by lamination and which is provided with a functional section (5) consisting of a screw (8) formed in the upper part of a mouth portion (4) and a stop ring (6) formed under the screw (8) and a neck ring (7) formed in the lowest part of the mouth portion (4) and a perform thereof, wherein the leading edge (3a) of the gas barrier layer (3) is set in the mouth portion (4) in such a way that the top of the leading edge (3a) does not reach the central part of the stop ring (6) constituting the functional section (5) to thereby enable the thermal crystallization of the mouth portion (4) without the influence of shrinkage and deformation due to the presence of the gas barrier layer (3) in the functional section (5) of the mouth portion (4).

摘要： The invention relates to a container for a product for dispensing, comprising a relatively stiff outer container (2) having at least one dispensing opening (3), and a deformable inner container (4) to be filled with the product which is accommodated in the outer container and which likewise has a dispensing opening (5). The inner container is connected to the outer container both in the vicinity of the dispensing opening and at least at one location remote therefrom. The connection is formed in that the outer container has an opening (8) through which protrudes at least one fixing element (10) connected to the inner container. This fixing element is pin-like and has an end part of which the dimensions are larger than those of the opening. The invention further relates to a method for manufacturing such a container.

摘要： Oxygen-scavenging polymers and packaging for holding oxygen-sensitive products. A heat treatment process has been found to significantly increase the oxygen-scavenging performance of the polymer. The enhanced scavenging polymer can be effectively incorporated into various packaging, including transparent multilayer containers for beer and juice. In one embodiment, a multilayer package made from the scavenger provides an actual reduction in oxygen content of a contents of the package, over a long period of time (e.g., 24 weeks). The package can be stored unfilled for an extended period (without significant loss of scavenging capability) and will scavenge substantially immediately upon filling with a liquid product. The package may incorporate a relatively low weight percentage of the scavenger, thus providing enhanced scavenging in a cost-effective manner.

摘要： A multi-layer bottle which comprises outermost and innermost layers made mainly of a polyester (A) and at least one barrier layer lying between the outermost and innermost layers, wherein the polyester (A) is a thermoplastic polyester resin obtained by polymerizing a dicarboxylic acid component containing at least 80% by mole of terephthalic acid with a diol component containing at least 80% by mole of ethylene glycol and the barrier layer comprises a polyamide (B) and a polyamide (C). The polyamide (B) is one obtained by polycondensing a diamine component containing at least 70% by mole of m-xylylenediamine with a dicarboxylic acid component containing at least 70% by mole of an α,ω-straight-chain aliphatic dicarboxylic acid having 4 to 20 carbon atoms, while the polyamide (C) has a saturation moisture content higher than that of the polyamide (B) as determined at 23°C, 50%RH and 1atm and is contained in an amount of 20% by weight or below based on the weight of the barrier layer. Since the bottle little causes ply separation due to falling or impact, it is not necessary to restrict the shape of the bottle to one having fewer depressions, projections, or crooks for the purpose of inhibiting ply separation. Thus, the bottle has high design freedom.
摘要翻译：一种多层瓶，其包括主要由聚酯（A）制成的最外层和最内层以及位于最外层和最内层之间的至少一个阻挡层，其中聚酯（A）是通过聚合二羧酸其含有至少80摩尔％对苯二甲酸与含有至少80摩尔％乙二醇的二醇组分，阻挡层包含聚酰胺（B）和聚酰胺（C）。聚酰胺（B）是将含有70摩尔％以上的间苯二甲胺的二胺成分与含有70摩尔％以上的具有4个碳原子的α，ω-直链脂肪族二羧酸的二羧酸成分缩聚而成的物质至20个碳原子，而在23℃，50％RH和1atm下测定，聚酰胺（C）具有比聚酰胺（B）高的饱和含水量，并且含量为20重量％或更低基于阻挡层的重量。由于瓶子由于掉落或冲击而很少产生层片分离，因此为了抑制层片分离，不必将瓶子的形状限制为具有较少凹陷，凸起或弯曲的形状。因此，瓶子具有很高的设计自由度。

摘要： A heat resistant polyester container comprising a body whose temperature (T) exhibited when the shrinkage factor of the formula: shrinkage factor (%) = (extent of shrinkage /gauge length) × 100 (1) (wherein the extent of shrinkage is measured by TMA under such conditions that no preliminary load is applied and the temperature rise rate from 30ºC is 3ºC/min with respect to a specimen cut from a body of polyester container so as to have a gauge length of 20 mm) is 0.66% is 120ºC or higher. The polyester container is excellent in heat resistance, enables performing retort sterilization at high temperature after charging and sealing of food, beverages, etc., and exhibits such a high heat resistance that, even after the retort sterilization, the body of the container is not deformed.
