A tamper indicating package comprising a container having a neck with a threaded finish, an annular bead on the neck, a plastic closure which includes a base wall and a depending peripheral skirt having threads interengaging the threads of the container, and a tamper indicating band attached to the skirt by a plurality of weakened portions defining a line of severing. An annular flange extends axially upwardly and inwardly from the tamper indicating band toward the base wall of the closure and comprises a first continuous annular flange portion connected to the band by a hinge portion and a second portion. The second portion comprises a plurality of segment portions extending upwardly and inwardly from the first continuous portion with the free ends of the segment portions engaging beneath the bead on the container when the closure is threaded onto the container. The flange is bent intermediate its ends so that the second portion extends inwardly at a greater angle than the first continuous flange portion. The segments are separated by narrow slits such that when the closure is fully applied on a container, and the closure is rotated to remove the closure, the free ends of the adjacent segment portions engage a bead on the container and are moved radially inwardly and the sides of the slits adjacent the free ends contact one another in an interfering manner to inhibit reversal of the segment portions and enhance resistance to removal.
