Abstract

Abstract Extended surface apparatus contained within a vessel for dispensing a liquid and connected to a nozzle assembly fitted to the vessel comprises an array or arrays of spaced apart elements and a communicating device connecting the array or arrays to the nozzle assembly. The elements are adapted to retain a predetermined dose of the liquid using the solid-liquid intermolecular attraction between the liquid and the elements when the elements come into contact with the liquid.
