Abstract
A tamper evidencing closure for use on containers containing food stuffs and the like comprises multiple cap configuration intrically joined to a closure by a live hinge. A secondary cap is formed within the first with frangible tamper evidence strips and a secondary live hinge. A tubular plug depends from the underside of said secondary cap and is registerable into a dispenser opening within the closure. Assembly pins secure the cap to the closure and a annular rib on the tubular plug forms a seal around the dispensing opening when the tubular plug is in closed position and holds the secondary cap and plug in closed position once the frangible tear strips are broken.
