Abstract
A dispenser closure for attachment to the threaded neck of a container includes a spout portion and a cap portion. The spout portion includes an annular wall, a shoulder and a depending skirt. A spout is integrally formed within the spout portion and is non-concentrically disposed with an area defined by the annular wall. The spout is substantially closed and has an inner channel which is in fluid communication with the interior of the container. The spout terminates at an upper end having an oval aperture and at a lower end at an inclined floor. A drainage opening is also formed in the spout portion and is in fluid communication with the interior of the container. The drainage opening is adjacent the annular wall and extends through the inclined floor and vertically onto the spout. The cap portion has a radially projecting annular shoulder with a depending collar. The collar is threaded on an interior surface to engage a threaded exterior surface of the upper end of the spout portion.
