Dispenser for fluid materials

A dispenser for fluid material such as cosmetic materials in the nature of mascara and the like is operative by one hand manipulation. The dispenser includes an internal reservoir for storage of an applicator attached to a post reciprocally received within a sleeve. A slider device is attached to the post having a portion accessible by the user. By one hand manipulation of the slider device, the applicator may be projected from the dispenser for use and retracted for storage. A closure member at one end of the dispenser may be opened and closed by manual manipulation or automatically by coupling to the slider device. Internal seals within the dispenser prevent evaporation of liquid and/or other volatile components of the fluid materials stored within the dispenser.
