A dispenser for dispensing a viscous material in a selected one of a multiplicity of configurations comprises a container having a squeezable body and neck with a discharge opening at its upper end. Engaged with the container is a closure body of generally circular cross section with a top wall and skirt. The top wall has a post with a discharge passage therethrough aligned with the neck discharge opening. A generally circular rotating disc is rotatably disposed on the closure body top wall and has a central hub seatin g said post. The post has an aperture alignable with the hub discharge passage for passage of viscous material therethrough. The disc has a multiplicity of flow openings spaced about the disc in a circular array and represents a multiplicity of configurations. The disc also has a multiplicity of flow channels extending from the post to the flow openings o f the disc, and it is rotatable to align the flow channel of the selected flow opening with the aperture in the post to permit viscous material to flow through the neck and top wall of the closure body into the post and outwardly in flow channels to a selected disc discharge opening.
