发明名称 CLOSURE BUTTON/PANEL ENERGY ENHANCEMENT
摘要 This relates to a closure cap having an end panel which is equipped with a central button or panel area so as to cause deflection, either by way of a vacuum within an associated container or by mechanical action when a container is closed. Recently, there has been developed a desire for a louder popping noise when the closure is removed. Also there has been developed tamper indicating indicia elements to be actuated by the button or panel area to irreversibly indicate that a container has been opened even though the closure cap has been reapplied. A need for a greater stored energy in the button or panel area has been found and such additional stored energy is obtained by utilizing faceted areas or portions.
