Abstract
A squeeze bottle atomizer comprised of a tube retainer having a product outlet port in a conical shaped central post through which fluid is expelled from within the container. A plurality of air inlet ports are located adjacent the central post and allow air to be forced and sucked out of the container when squeezed as well as return and be sucked into the interior of the container when the container is released. The orifice cup has an annular mixing or turbulence chamber wherein the air and the fluid from within the container are mixed before being expelled out of the orifice cup through a discharge orifice. The axis of the product outlet port is coincident with the axis of the 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.
