Abstract
A closure assembly for a retractable instrument having an applicator element comprises at least two fingers and a sleeve operatively coupled with the at least two fingers. When the retractable instrument is in a retracted position, the sleeve constrains the fingers such that the fingers are in a fully closed state around the applicator element. Protraction of the sleeve and relative movement between the fingers and the sleeve allows the fingers to open, thereby exposing the applicator element. Thus, the closure assembly opens to expose an applicator element such that the applicator element is in an application position.
