Abstract
A pilfer-proof plastic cap for sealing containers. The cap comprises a cap body, a band member and an annular wall extending upwardly and radially inward from the band member. A plurality of stopper tabs formed in the annular wall is engagable with the threads of a threadably capped container. The stopper tabs have a saw-tooth shape including a mildly inclined leading surface for smooth engagement of the cap with the container threads. The band member is connected to the cap with breakable ridges to indicate tampering. The band itself contains a breakable ridge to ease removal of the band from the container.
