Abstract
A hermetically sealed container has a closure connected to the container by a frangible web and is provided with a unitary drop dispenser suitable for dropwise dispensing of a liquid contained therein. A hollow container body defines a liquid enclosure and has a dispensing nozzle that is unitary with the container body at a proximal end thereof. A hollow, campanulate chamber is situated at the distal end of the nozzle. The dispensing nozzle defines a liquid flow passageway in communication with the liquid enclosure and with the companulate chamber, and has a substantially uniform inside diameter. The hollow, campanulate chamber has a maximum inside diameter that is larger than the inside diameter of the liquid flow passageway and defines a drop dispensing aperture having an inside diameter that is smaller than the inside diameter of the liquid flow passageway. The drop dispensing aperture is defined by an annular flange that is connected to a closure cap at a frangible web. The drop dispensing aperture is exposed for dropwise dispensing of the contents of the container when the frangible web is fractured and the closure cap is removed.
