A propel/repel dispenser having one or more features in combination to provide improved manufacture, assembly and use of the dispenser is described. Such features include a wide single lead thread, a "click" feature to provide sound and feel to a user so that propelling and repelling can be controlled, and a retention means involving a single slot extending from a central opening through which a screw structure passes upon assembly of the dispenser.
