    Abstract: A tamper-evident closure includes a cap having an interior, threaded peripheral skirt, a tamper-evident ring disposed below the lower edge of the skirt and a plurality of elongate bridge members interconnecting the tamper-evident ring to the cap. Each bridge member includes a lower end forming a lower juction with the ring an upper end thinner than the lower end forming an upper juction with a surface of a recess formed in the skirt. Each bridge member is designed to break at the upper end thereof when the closure is rotated in a direction to remove it from the container, and each bridge member is inclined upwardly at an acute angle to the ring from the lower to the upper junction, in the direction in which the cap is required to be rotated to remove it from the container.
