Abstract
A tamper-evident closure for containers includes a closure shell having a top surface and a depending skirt. The top surface defines a first aperture therethrough and a frangible portion. The skirt defines an open lower end for engaging a container. A tamper-evident tearable member overlies the top surface of the closure shell and defines a second aperture overlying the first aperture. A removable closure cap overlies the top surface of the closure shell and the tearable member. The closure cap has an annular ring projecting downwardly from an underside of the closure cap and extending through the first and second apertures. The annular ring attaches to an underside of the frangible portion. At least partial removal of the closure cap from the top surface of the closure shell peels the frangible portion away from the top surface of the closure shell along the scoring, and tears the tamper-evident member.
