Abstract: An extendable applicator is disclosed for reaching the contents of the lowermost portion of a bottle. The extendable applicator has an upper pushbutton cap that moves up and down within a base cap member and to which an applicator brush is attached. An insert base is arranged within the lower portion of the base cap and has a flat upper surface that, together with the flat bottom of the upper pushbutton cap, supports a coil spring. The insert base also has a hole for the applicator brush to fit through. Finally, the extendable applicator includes a threaded piece for attachment of the extendable applicator to an externally threaded bottle. The applicator brush optionally contains a clear plastic cap to cover the upper pushbutton cap and a lip is provided on the upper external surface of the base cap to accommodate the clear plastic cap.
