ABSTRACT:
A prescription vial which counts cyclically, through a window in the cap, how many times it has been opened/closed that day. The construction is unique in that the principal parts can be formed with straight strokes of the forming press, thus they are suitable for mass production. Spring fingers on an index plate extend past the sealing disc to ride on the upper flank of the closure threads. The fingers touch the thread at a flat helical angle. When the cap is rotated in one direction the index plate and fingers move with it; in the other direction the cap turns but the fingers will not pass an abutment on the thread, so force the index plate to turn inside the cap.
