    Abstract: A piston assembly (10) for a flowable materials container having a barrel (14) defining a fluid containing chamber (16). The barrel (14) is made of a body of a cyclic olefin containing polymer or a bridged polycyclic olefin containing polymer. An elastomeric piston (24) is slidably attached to the barrel (14) and provides a seal of the chamber. The piston (24) has a parylene coating on an outer surface thereof to reduce the necessary break away force. A plunger (22) is also provided and has a second mating member (42) removably connecting the plunger to a first mating member (44) of the piston. The first mating member (44) has a series of threads having a major diameter and a minor diameter, and the second mating member (42) has a series of threads having a major diameter and a minor diameter. The major and minor diameters of the second mating members (42) is appreciably smaller than the major and minor diameters of the other of the first mating member (44) to provide ease of connection.

    Abstract translation: 一种用于可流动材料容器的活塞组件（10），其具有限定流体容纳室（16）的桶（14）。 桶（14）由含环烯烃的聚合物或含桥联多环烯烃的聚合物构成。 弹性活塞（24）可滑动地连接到筒体（14）并提供腔室的密封。 活塞（24）在其外表面上具有聚对二甲苯涂层以减少必要的分离力。 柱塞（22）也被提供并且具有第二配合构件（42），该第二配合构件将柱塞可移除地连接到活塞的第一配合构件（44）。 第一配合构件（44）具有一系列具有大直径和小直径的螺纹，并且第二配合构件（42）具有一系列具有大直径和小直径的螺纹。 第二配合构件（42）的主直径和次直径明显小于第一配合构件（44）中的另一个的主直径和次直径以提供连接的容易性。

    Abstract: A disposable infuser is provided having a source of pressurized liquid contained in a liquid chamber (14). The liquid chamber (141 includes housing (20) defining an access aperture (83). A oneway duck-bill valve (80) is contained in the access aperture (83). A separate outlet conduit (84) is provided having a blunt cannula (98). When the outlet conduit (86) is attached to the housing (20). the blunt cannula (98) extends into the duck-bill valve (80) sufficiently to open the duck-bill valve (80) to establish fluid communication between the source of pressurized liquid (14) and the outlet conduit (84).
