Abstract
A threaded tamper indicating closure-container package provides an indication of initial opening by how far the closure threads onto the container neck. In the original package condition the bottom of the closure skirt is adjacent a shoulder on the container. After the package has been initially opened and the closure reapplied, the bottom of the closure skirt is noticeably above the container shoulder. A word message such as "opened" can also be exposed on the container neck between the shoulder and the bottom of the closure skirt when the closure is reapplied.
