[origin: US4276988A] A tamper-proof closure includes a seal cap and a lock ring for securement to a container having a screw cap. The lock ring has a first portion integrally formed with the bottom of portion of the seal cap and a second portion which is breakably detachable from the seal cap. The second portion of the lock ring is secured to the seal cap by spaced severable attachments. The first and second portions are separated by recesses one of which receives a projection on the container. The seal cap is secured over the screw cap by lips which are formed at its bottom edge and which catch the bottom edge of the screw cap.
