A tamper-indicating closure system used with a container that has a sealing disc over the neck of the container. The closure threads onto the container neck but is held against threading down below a predetermined level by a rupturable tear band between the bottom of the closure and the shoulder of the container. A pourout dispenser feature is incorporated in the closure and after the tear band is removed, the continued threading-on of the closure will cause a member in the closure to rupture the sealing disc and the contents of the container can be poured therefrom through the closure. If the tear band is intact, tampering has not occurred.
