A dispenser for dispensing a viscous material in a selected one of a multiplicity of configurations comprises a container for a volume of a viscous material and having a squeezable body and a neck with a discharge opening at its upper end. Engaged on the container is a closure body of generally circular cross section having a top wall and a skirt, and the top wall has a discharge passage therethrough aligned with the discharge opening of the neck. The body top wall has a generally circular recess therein extending from the periphery thereof and beyond the discharge passage of the closure. Disposed in the circular recess is a generally circular rotating disc which has a multiplicity of discharge openings spaced about the disc in a circular array, and the discharge openings have a multiplicity of configurations. The disc is rotatable to align a selected discharge opening with the discharge passage in the top wall to permit viscous material to flow through the neck and the top wall of the closure body into and through a selected disc discharge opening.

Having thus described the invention, what is claimed is: 1. A dispenser comprising: (a) a container for a volume of a material and having a squeezable body and a neck, the neck of the container having an opening at its upper end; (b) a closure body of generally circular cross section having a top wall and a skirt extending from the periphery of the top wall, the skirt defining an outer surface of the closure body, the top wall having a discharge passage therethrough aligned with the opening of the neck, the closure body having means thereon engaging the container, the top wall having a generally circular recess; and (c) a generally circular disc disposed in the circular recess, the disc having a peripheral edge and having a multiplicity of discharge openings spaced thereabout in a circular array, the discharge openings having a multiplicity of configurations, the disc being rotatable in the recess to align a selected discharge opening with the discharge passage in the closure top wall to permit material to flow through the neck and top wall of the closure into and through the selected disc discharge opening; (d) wherein at least a portion of the peripheral edge of the disc extends beyond the outer surface of the closure body such that the disc may be rotated by the application of force to the portion of the peripheral edge of the disc; (e) wherein the discharge passage is located within the circular recess and is positioned generally in the center of the top wall, and further wherein an axis of rotation of the disc is located between the outer surface of the closure body and the discharge passage. 2. The dispenser of claim 1 wherein the container neck is externally threaded and wherein the bottom surface of the closure body top wall has a depending threaded barrel threadably engaged on the neck. 3. The dispenser of claim 1 wherein the container is a flexible tubular member sealed at the end opposite the neck. 4. The dispenser of claim 1 wherein the closure includes an overcap having a top wall and a peripheral skirt. 5. The dispenser of claim 4 wherein the lower surface of the top wall of the overcap includes a circular boss concentric therewith and bearing on the disc. 6. The dispenser of claim 1 further comprising an aperture in the closure body top wall and a mounting post on the disc which snaps into the aperture. 7. A closure configured to be coupled to a container, the closure comprising: (a) a top wall, the top wall having a recess, a peripheral edge and a discharge passageway; and (b) a disc including a peripheral edge and a plurality of discharge openings, the disc positioned in the recess and attached for movement to the top wall, the disc sized such that at least a portion of the peripheral edge of the disc extends beyond the peripheral edge of the top wall, the peripheral edge of the disc engageable for movement from beyond the peripheral edge of the top wall to allow a user to move the disc to selectably align one of the plurality of discharge openings with the discharge passageway; wherein a radius of the disc at the portion of the peripheral edge of the disc that extends beyond the peripheral edge of the top wall is less than the radius of the top wall. 8. The closure of claim 7 further comprising a skirt extending from the peripheral edge of the top wall and a barrel extending from a bottom surface of the top wall, the barrel configured to be coupled to a neck of the container. 9. The closure of claim 8 wherein the barrel is threaded to engage threading located on the neck of the container. 10. The closure of claim 7 wherein a first discharge opening of the plurality of discharge openings has a first configuration and a second discharge opening of the plurality of discharge openings has a second configuration, the second configuration being different from the first configuration. 11. The closure of claim 7 wherein the recess of the top wall is a generally circular recess, and further wherein the disc is generally circular and is rotatably attached to the top wall within the recess. 12. The closure of claim 11 wherein the recess includes an aperture and the disc includes a mounting post which snaps into the aperture of the recess, the disc being rotatable about the axis of the mounting post. 13. The closure of claim 7 wherein the closure is coupled to a container. 14. The closure of claim 13 wherein the container is squeezable to force contents of the container through the plurality of discharge openings. 15. The closure of claim 7 further comprising an overcap, the overcap having a ring boss extending from a bottom surface of the overcap, wherein the disc includes a recess around the upper end of a first discharge opening of the plurality of discharge openings, wherein the overcap is movable from an open position to a closed position, and further wherein the ring boss of the overcap is configured to seat within the recess around the upper end of the first discharge opening when the overcap is moved to the closed position. 16. The closure of claim 15 further comprising a living hinge coupling the overcap to the top wall. 17. The closure of claim 7 further comprising an annular ring extending from a top surface of the top wall around the discharge passageway. 18. The closure of claim 17 further comprising a recess positioned on a lower surface of the disc around a first discharge opening of the plurality of discharge openings, wherein, when the disc is moved to align the first discharge opening with the discharge passageway of the top wall, the annular ring seats within the recess positioned on a lower surface of the disc around the first discharge opening. 19. The closure of claim 7 wherein the discharge passageway is positioned in the center of the top wall. 20. The closure of claim 7 wherein the peripheral edge of the disc includes a plurality of teeth. 21. The closure of claim 7 wherein the recess extends from the peripheral edge of the top wall beyond the discharge passageway of the top wall. 22. The closure of claim 7 wherein a second portion of the peripheral edge of the disc is positioned within an area defined by the peripheral edge of the top wall. 23. The dispenser of claim 1 wherein a radius of the disc is less than the radius of the top wall of the closure body. 24.
