Abstract

This relates to a closure for a container in the form of a closure cap which is provided with a mechanically actuated button. The button is centrally located and is generally in a recessed position. The button is surrounded by a plurality of dished areas which, when the closure is applied, will engage the end sealing surface of a container and cause a deflection of the dished areas which will result in an annular portion of the closure surrounding the button to invert and to project the button axially upwardly from its original recessed position to a projecting position. The closure may be enhanced by other tamper indicating arrangements which are sealed to the closure by way of a translucent panel overlying the end panel of the closure and being bonded at its periphery to the closure. The translucent panel will be provided with a layer of material generally axially aligned with the button and the button will be provided with a layer of adhesive, preferably contact adhesive. The layer of material carried by the translucent panel may be formed of a frangible material or may be removed from the translucent panel either to remove a message or to make a message visible.
