Abstract
A closure for dispensing a viscous material such as mustard or ketchup from a container includes a threaded closure body having a dispensing orifice through which viscous material may flow during dispensing, and a collection space for collecting a volume of thin liquid that may form on top of the viscous material during storage. The collection space acts to intercept the thin liquid as the container is inverted to dispense the viscous material. As the material continues to be dispensed, the thin liquid is re-mixed into the material, thereby keeping the solid to liquid ratio of the material in the container relatively constant. Additionally, a valve may be placed in the orifice for at least partially precluding passage of the thin liquid through the orifice during initial dispensation.
