Abstract
Abstract A tamper indicating package comprising a container having a neck with a threaded finish and a closure which includes a base wall and depending peripheral skirt having threads interengaging the threads of the container, and a tamper indicating band attached to the skirt by a plurality of circumferentially spaced frangible bridge members. The tamper indicating band includes a bead for engaging a complimentary bead on the container, and a segmented annular flange extending axially upwardly and inwardly from the lower edge of the tamper indicating band towards the base wall of the closure. The annular flange has its free edge formed with a plurality of segments such that the stiffness of the flange is reduced. In addition, the leading end of each segment is cut to a 30° angle. These two features facilitate the application of the closure to the container.

Claim 1
Independent Claim
180 words
A tamper indicating package comprising a container having a neck with a threaded finish and an annular bead on the container, a closure which includes a base wall and depending peripheral skirt having threads interengaging the threads of the container, and a tamper indicating band attached to the skirt by a plurality of circumferentially spaced frangible bridge members, a segmented annular flange extending axially upwardly and inwardly from the lower edge of the tamper indicating band towards the base wall of the closure adapted to engage the bead on the container and flex radially inwardly when the closure is threaded on the container and thereafter engage beneath the bead on the container, said annular flange having its free edge formed with a plurality of segments such that the stiffness of the flange is reduced, the leading edge of each segment being at an acute angle extending rearwardly with respect to the direction of threading the closure on the container such that the application of the closure over the bead during the threading of the closure on the container is facilitated.
Claim 2
Dependent Claim
