Abstract
A dripless spout comprises a surface having a lip over which a liquid to be poured may flow, and a channel formed in the surface and extending over at least a portion of the surface to the lip. At the end of a pouring operation any droplets of liquid remaining on the surface occupy the channel and are held therein. The spout is formed of relatively thin material and may be provided in the form of a spring clip for fitting to a liquid container, or may be formed integrally with a liquid container.
