Abstract
Described are metering dispensers having a body configured to hold a flowable composition in a chamber, a drive screw coupled to the body, and a plunger threadingly coupled to the drive screw. The plunger includes at least two annular lips that form a fluid seal with the chamber as the plunger travels along the drive screw through the chamber. A base is rotationally coupled to the body with a cam that contacts at least one tab extending externally from the body so that the tab enters at least one low point on the cam by traveling over a trailing edge of the low point, and the trailing edge then prevents the tab from exiting the low point in the direction of the trailing edge.
