Abstract
Abstract A dripless pouring cap having a funnel-shaped pouring spout with an outwardly curved pouring lip is screwed onto a container. Below the pouring lip are two catch basins to trap small amounts of liquid that has dripped from the pouring lip. A hinged lid is pivottally connected to the cap to facilitate opening and closing of the pouring spout. The catch basins and lid are so arranged so that opening and closing of the lid will not splash liquid trapped in the catch basins.
