Abstract
Abstract This disclosure relates to tamper-indicating closures of the type which include a nozzle and a closure cap. In order that tampering may be readily apparent, the closure cap is provided with one or more straps which have their opposite ends permanently secured to the nozzle in any desired manner. The straps are of a length so that when the closure cap is removed from the nozzle, rupture of the straps is required. The straps may be suitably weakened to facilitate the rupture thereof.
