Abstract
A tamper evident closure device having a closure with an internally threaded skirt with a groove therein between radially outer and inner skirt portions to receive a tamper evident band having an inwardly extending bead which engages under a transfer ring of a container to hold the tamper evident band down and hence separate it from the closure as the closure is unscrewed from the container. A method of simultaneously stripping the closure and tamper evident band from a common mold core is also disclosed.
