Abstract
Abstract A tamperproof closure is described for sealing containers such as soda, liquor or other bottles. The closure is a unitary molded closure cap which includes a tamper indicating band. The indicating band is applied with the closure cap and is locked onto a bead on the container so that it is torn free from the upper sealing portion of the cap as soon as an attempt is made to turn the closure cap off of the container.
