Abstract
A container lid having a tamper evident and tamper resistant band formed of a plurality of equally spaced tabs having spurs that engage the rim of a container with latches formed on the spurs. In one embodiment the tamper evident band is unique because it hinges up instead of down and has a plurality of spurs with a stepped edge forming latches with the spurs engaging slots around the periphery of the lid. The reverse action makes the step edges on the spurs on the inside of tabs formed on the tamper resistant strip pull tighter when any attempt is made to pry or remove the lid from a container or cup. The lid also includes an annulus having interior surfaces that provide an excellent seal both inside and outside of the cup when the tamper resistant band is removed. In a second embodiment a tamper resistant band is formed with a curved surface to engage the exterior surface of the cup and has a plurality of spurs with a detent forming a latch to engage the lower edge of the skirt around the periphery of the lid. Each tab on the tamper resistant and tamper evident band has preferably two spurs.
