A container assembly includes a container that has an externally threaded finish portion as well as retention structure for preventing upward movement of a tamper evident band. The container assembly further includes a closure having a body portion of a base and an internally threaded downwardly depending sidewall portion that is sized and shaped to screw onto the finish portion of the container. The closure further includes a tamper evident band that is frangibly connected to the sidewall portion and that includes a main band portion and a J-hook retention member. The J-hook retention member includes a plurality of pleated retaining flaps, each of which has upper portion for engaging the retention structure. Advantageously, at least one of the pleated retaining flaps is further constructed and arranged to engage the container so as to resist rotation with respect to the container, whereby separation of said tamper evident band from said body portion is better assured when the closure is unscrewed from the container.
