Abstract
An assembly includes a container and a closure. The closure includes a tamper-indicating band having a plurality of sloping teeth. Each of the sloping teeth of the tamper-indicating band has an engagement surface that is engageable with one of the engagement surfaces of the sloping teeth of the container. The sloping teeth on the tamper-indicating band are configured such that when one of the teeth on the tamper-indicating band completely engages one of the teeth on the exterior surface of the neck of the container, the engagement surface of at least one of the other sloping teeth on the tamper-indicating band is free from engagement with the engagement surfaces of the sloping teeth of the container and the engagement surface of at least one of the other sloping teeth of the container is free from engagement with the engagement surfaces of the sloping teeth on the tamper-indicating band.
