Abstract
Abstract A tamper indicating package comprising a container having a neck with external threads thereon, a radial bead beneath the threads, and a closure having a base wall and a peripheral wall with internal threads on the peripheral wall complementary to the threads on the container. The closure having a radially extending lip at the free end of the peripheral skirt. A tamper indicating band comprises a continuous annular wall, an upper radially inwardly extending flange for engaging the lip on the closure, and a lower generally radially inwardly and upwardly extending flange for engaging the flange on the container. The lower flange is discontinuous such that the tamper indicating band can be applied to the closure and container after the closure has been applied to the container by moving the band axially downwardly and causing the lower flange to flex radially outwardly and then snap radially inwardly beneath the flange of the container. The tampering indicating band includes weakened portions such that when the closure is rotated to remove the closure from the container, the lift force of the threads causes the band to be severed.

Claim 1
Independent Claim
186 words
A tamper indicating package comprising a container having a neck with external threads thereon, a radial flange beneath the threads, a closure having a top wall and a peripheral skirt with internal threads on the peripheral skirt complementary to the threads on the container, said closure having a radially extending lip at the free end of the peripheral skirt, and a tamper indicating band comprising a continuous annular wall, an upper radially inwardly extending flange for engaging the lip on the closure, and a lower generally radially inwardly and upwardly extending flange for engaging the flange on the container, said lower flange being discontinuous such that the tamper indicating band can be applied to the closure and container after the closure has been applied to the container by moving the band axially downwardly and causing the lower flange to flex radially outwardly and then snap radially inwardly beneath the flange of the container, said tamper indicating band including weakened portions such that when the closure is rotated to remove the closure from the container, the lift force of the threads causes the band to be severed.
