Tamperproof port cover

摘要

A tamper resistant cover for the port of a container for medical liquids which when applied to the port indicates that an additive material has been introduced into the container. The port cover is easily molded from a resinous plastic material and includes latch portions which fit into a latch bar with the latch bar serving as a means to prevent access with the latch portions so as to result in a tamper-resistant structure. Preferably, the latch portions are in the form of barbed sections and are guided by means of an inclined ramp into latch openings in such a manner that a compression fit is provided so that after the barbed sections are forced through the latch openings the barbed sections will expand to engage latch surfaces in the latching bar.
