<p>The dispenser (10) has housings (12, 14), a liquid reservoir (12), a discharge port (20) delivering a liquid from the liquid reservoir. A concave or convex drop formation surface (30) surrounds the discharge port, at which the liquid collects to enable the liquid drop as a dropping on the drop formation surface. The drop formation surface comprises an expressed confinement contour, which includes molds in a circular shape. The confinement contour of the drop formation surface is formed by a boundary edge with a radius of curvature of less than 0.1 mm.</p> |
