ABSTRACT:
A tamper proof cap for use on container having a threaded neck. The cap includes a top portion, an annular skirt portion depending from the top portion and a separable strip depending from the bottom of the skirt portion. The boundary between the skirt portion and separable strips is defined by a line weakness. The skirt portion has internal threads that complement threads on an upper portion of the container neck. A portion of the separable strip has internal teeth that engage notches on a lower portion of the container neck. At the end of the strip is a tab which is grasped and pulled to sever the strip from the skirt along the line of weakness, thereby allowing the skirt portion to be unthreaded. The teeth of the strip and the container notches are constructed to allow the teeth to slide past the notches upon rotation of the cap in clockwise threading direction while causing the teeth to engage the notches to prevent rotation of the cap in a counterclockwise unthreading direction.
