    • A method of preparation of valves for a flat, flexible, sterilizable container capable of sterilely containing a liquid to be removed under absolutely sterile conditions which comprises the steps of:forming a two-layer laminate including a first layer of a copolymer of ethylene with a minor proportion of butylene and a second layer of an amide polymer; forming a pocket in the two-layer laminate wherein the first layer forms the inner surface of the pocket; providing an elastomeric core element having spaced major faces; inserting the core element into the pocket in the two-layer laminate; providing a three-layer laminate including a first outer layer of a major portion of a propylene polymer, a second outer layer of a copolymer of ethylene with a minor proportion of butylene, and an intermediate layer of an amide polymer; orienting the three-layer laminate so that the second outer layer thereof is apposed to the first layer of the two-layer laminate; expelling air surrounding the core element in the pocket; welding contacting portions of the two- and three-layer laminates to each other and bonding the second outer layer of the three-layer laminate to one of the major faces of the core element and the first layer of said the two-layer laminate to the other major face of the core element and; cutting through the two- and the three-layer laminates in the region of the weld at a distance removed from the core element, whereby a circular area of the weld remains around the core element.
    • 一种制备用于无菌地包含要在绝对无菌条件下被去除的液体的扁平,柔性,可消毒的容器的阀的方法,该方法包括以下步骤:形成双层层压材料,其包括第一层乙烯共聚物与 较小比例的丁烯和第二层酰胺聚合物; 在所述双层层压体中形成袋,其中所述第一层形成所述袋的内表面; 提供具有间隔开的主面的弹性体芯元件; 将芯元件插入双层层压板中的袋中; 提供包括丙烯聚合物的主要部分的第一外层和乙烯与少量丁烯的共聚物的第二外层和酰胺聚合物的中间层的三层层压体; 使三层层叠体定向,使其第二外层附着到双层层压体的第一层; 排出围绕口袋中的核心元件的空气; 将所述两层和三层层压体的接触部分彼此焊接并将所述三层层压体的第二外层与所述芯体的主要表面和所述两层层压体的第一层粘合到 核心要素的其他主要面孔; 在与芯体元件相距一定距离处的焊缝区域中切割两层和三层层压板,由此焊缝的圆形区域保留在芯体周围。

    • A method and apparatus for producing and filling sterilized bags includes the steps of: feeding a film material from which the bags are formed from at least one reel; printing information on the film; cleaning the film in two stages which includes ultrasonic vibration and washing with water; drying the film; sterilizing it with ultraviolet rays; applying valves to the film; welding, punching and printing the film to generate a large bag; filling the large bag with liquid and inert gas; applying a second welding orthogonal to the first welding direction to divide the larger bag into a plurality of final bag having a predetermined size; cutting the film into the individual bags and testing the integrity of each bag; and vacuum packaging the bags and/or megablistering it. The foregoing process steps can be realized with an apparatus which includes at least a film unwinding unit having a braking device; at least one ultrasonic washing tank and at least one tank with water nozzles which is fed from a recycling plant which supplies distilled water; a film alignment device which is positioned ahead of a folding prism which is used for folding the film; and a double filling pipe and a test band which operates in synchronism with a transport roller.
    • 一种用于生产和填充无菌袋的方法和装置包括以下步骤:从至少一个卷轴送入形成袋的薄膜材料; 打印电影信息; 在包括超声波振动和水洗两个阶段清洁该膜; 烘干胶片; 用紫外线杀菌; 将膜施加到膜上; 焊接,冲压和印刷胶片以产生大袋; 用液体和惰性气体填充大袋子; 施加与第一焊接方向正交的第二焊接,以将较大的袋分成具有预定尺寸的多个最终袋; 将胶片切成各个袋子,并测试每个包装袋的完整性; 并真空包装袋子和/或使其成型。 上述工艺步骤可以通过包括至少具有制动装置的薄膜退绕单元的装置来实现; 至少一个超声波洗涤槽和至少一个具有水喷嘴的罐,其从供应蒸馏水的再循环设备供给; 位于折叠棱镜前方的胶片对准装置,该折叠棱镜用于折叠胶片; 以及与输送辊同步地操作的双重填充管和测试带。
