Metering dispensers include 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.

Metering dispenser for flowable compositions

Described are applicators having a plunger with a plunger body, and a tube having a receptacle end for insertion of the plunger, and a connector end formed of flexible plastic material having a bull-nose shape. As an example, the plunger body can include a viewing window. As another example, the connector end has an internal surface that is free of threaded connectors. The connector end can also have a snap-fit coupling design to couple to a snap-fit nozzle. The snap-fit nozzle can be connected to an adaptor cap or an administering tool of a metering dispenser.
