Abstract
An overcap includes a closure and a tear strip. The closure includes two “permanent” retainer flanges adapted to engage an underside of an annular lip included in a can and arranged to surround a dispenser nozzle. The tear strip includes two “temporary” retainer flanges adapted to engage the underside of the annular lip to help retain the overcap on the can until the tear strip is separated from the closure.
