Abstract
An airless squeeze bottle sprayer comprised of a tube retainer, an orifice cup and a closure. The tube retainer has a product outlet port, a post, and at least one tangential apertures through which fluid is expelled from within the container. The orifice cup has an annular mixing or turbulence chamber wherein the fluid from within the container is mixed up before being expelled out of the orifice cup through a discharge orifice. A dip tube depends from the tube retainer and defines a path for the fluid from the bottom of the container to the annular mixing chamber. When the container is squeezed, fluid is forced up through the dip tube into the mixing chamber and out of the container through the discharge orifice in the orifice cup. Any air that is introduced into the container and expelled out of the container is done so through the same path as the fluid, the sprayer lacks any distinct or separate air ports.
