SCREW-BASED DISPENSER HAVING LOCKING ELEVATOR AND ELEVATOR RETENTION MECHANISM

摘要

A screw-based dispenser for the application of cosmetic products and other applicable gels, liquids, and solids. The screw-based dispenser may have one or more of the following features: a cylindrical outer casing having at least two diametrically opposed feedback struts, a threaded screw connected to a base that is rotatable relative to the cylindrical outer casing, an elevator retention mechanism, a movable elevator operably engaged with the threaded screw within the cylindrical outer casing, and an elevator locking mechanism providing resistance to spontaneous axial movement of the elevator toward an end of the threaded screw opposite the rotatable base.

1. A screw-based dispenser comprising:
a cylindrical outer casing having a center hole and at least two diametrically-opposed feedback struts at a non-dispensing end; a threaded screw having a first end and a second end, where the threaded screw is connected at the first end to a base, and the threaded screw comprises at least two diametrically-opposed feedback flaps disposed near the first end and a elevator retention mechanism disposed near the second end, wherein the screw is inserted through the center hole of the cylindrical outer casing until the base is disposed adjacent to the non-dispensing end of the cylindrical outer casing; a substantially cylindrical movable elevator having a central opening through which the threaded screw is inserted and an engagement wall that is operably engaged with the threaded screw within the cylindrical outer casing; and an elevator locking mechanism.
