<p>A micro-emitter for pressure packages comprises an apertured member disposed across the nozzle opening through which a fluid product in the pressure package is expelled. The apertured member has at least one aperture which is from 0.5 to 15 mu in diameter. In one instance, propellant pressure is used to force the fluid through the aperture and break it into small drops. In a second instance a high velocity stream of vapor is used to assist the break up of the liquid either before the apertured member or after the fluid is forced through the apertures.</p> |
