An airless applicator may deliver high/low viscosity liquids or semi-liquids, and contains a valve controlling flow between a product reservoir and an intermediate pooling area, while a narrow opening between the intermediate pooling area and a product dispensing chamber controls flow therebetween.

An airless applicator may deliver high/low viscosity liquids or semi-liquids, and contains a valve controlling flow between a product reservoir and an intermediate pooling area, while a narrow opening between the intermediate pooling area and a product dispensing chamber controls flow therebetween. This arrangement prevents backflow to the product reservoir, precluding an influx of contamination therein. Product delivery is by specially adapted applicator heads. In one embodiment, a plurality of prongs, and openings into the product dispensing chamber, permit application of mascara onto eyelashes. Alternating prong heights increases effectiveness in applying mascara onto all sides of a user's lashes. Other applicator heads are configured for lip product applications such as for lipstick, and for eye products such as eyeliner and eye shadow. An air-tight sealing cap having a spring biased inner cap member may prevent moisture from escaping from the product dispensing chamber and prevent entry of contaminants therein.
