A tamper-evident closure cap and corresponding container have projections on a skirt of the cap corresponding to projections on a neck of the container. The skirt is connected to a remainder of the cap by a series of severable tabs. The projections are shaped to override one another when the cap is turned onto said container but to interlock with one another when the cap is turned off said container. When the projections interlock, the force exerted on the cap severs the tabs, thereby severing the skirt from the cap and providing evidence of tampering. The cap and container are operable over a wide range of tolerances and the tabs can be very small when compared to previous caps and containers. |
