    • PURPOSE: A syringe is disclosed having an elongated cylindrical tube open at both a first and second end. CONSTITUTION: A first open end of the elongated cylindrical tube (12) provides both a filling and dispensing opening (16) for the contents of the tube. A cylindrical piston (26) is slidably mounted within the tube and has a first axial end facing the fill and dispensing opening and a second axial end facing the opposite or second opening. The piston has an outside diameter slightly smaller than the inside diameter of the tube so that an annular clearance space (36) is formed between the tube and the piston. A wiper (38) extends radially outwardly from the second end of the piston and frictionally engages the cylindrical internal surface of the tube. A novel tamper evident cap (42) is also disclosed for closing the second end of the tube.
    • 目的:公开一种注射器,其具有在第一端和第二端处均开口的细长圆柱形管。 构造:细长圆柱形管(12)的第一开口端为管的内容物提供填充和分配开口(16)。 圆柱形活塞(26)可滑动地安装在管内并且具有面向填充和分配开口的第一轴向端和面向相对或第二开口的第二轴向端。 活塞的外径略小于管的内径,使得在管和活塞之间形成环形空隙(36)。 擦拭器(38)从活塞的第二端径向向外延伸并且摩擦地接合管的圆柱形内表面。 还公开了一种新颖的防篡改盖(42),用于封闭管的第二端。
