<p>A dispenser has a reservoir to hold a fluid, in at least one embodiment a viscous cosmetic, with a pump and a set of groove protrusions attached integrally. The dispenser fits within an outer casing that houses the reservoir and has a set of grooved passages with a flat upper section, a flat lower section, and a slope in between which seat the set of groove protrusions. The dispenser is raised and lowered within the outer casing with a hollow rotating body that has a set of straight grooves that simultaneously seat the set of groove protrusions so that when the hollow rotating body is twisted on top of the outer casing, the dispenser can move up or down. The hollow rotating body also has a notch to seat a button and nozzle actuating top when the dispenser is rotated to its lowest position. When the button and nozzle are depressed, fluid is dispensed through the nozzle. More or less fluid is dispensed depending on how high the dispenser is raised with respect to the outer casing.</p> |
