ABSTRACT:
A closure for a container with a top cut tamper evident feature and including an overcap rotatably attached to a container end portion. The container end portion is provided with an integral, hollow raised annular rib having a first truncated end and a second, inclined end, the two ends separated by a weakened hinge portion. The overcap is provided with a raised, open-bottomed, channel with a first open end and a second inclined end forming a knife blade, the channel overlaying and engaging the raised rib so that when the overcap is rotated, the knife blade severs the rib and moves it up the inclined end. Once the entire rib is severed, the combined container end and overcap may be detached from the container by tearing the hinge. The overcap and closure may be provided with cooperating means to permit the closure to be reattached to the container.
