BROKEN SEAL DETECTOR ABSTRACT OF THE DISCLOSURE It is difficult to detect whether the rubber seal on a vial or on a hypodermic syringe cartridge has been penetrated, because the rubber seal over the mouth of the container is purposely soft and self-sealing to prevent contamination of the fluid within the container. As a result pilfering of narcotics from such containers has gone largely undetected. To remedy this situation, a blister-like sac of a plastic film and containing a harmless dye is mounted within the mouth of the con- tainer between the rubber seal and the contents of the container. It is impossible for a hypodermic needle to be inserted through the seal and into the fluid within the container without puncturing the blister-like sac and thereby releasing the harmless dye into the fluid within the container. Thus, if the seal has been broken, the fluid in the container will be tinted with the color of the harmless dye.
