Abstract
A hermetically sealed container including a dispensing nozzle and a hollow closure with a lobate region removably secured thereto along a frangible web. The lobate region in the hollow closure reduces the retention of liquid droplets against the closure inner surface. The nozzle includes a straight inwardly and upwardly tapered wall which causes liquid droplets or aliquots in the closure and the nozzle to pass downwardly into the body of the container. As a result, liquid is not splashed when the closure is severed from the nozzle along the frangible web.
