Patent ID: 8562556

Claim:
A dispensing device comprising: a body portion surrounding a body cavity; a tip portion having a fluid path that is fluidly connected to the cavity, the tip portion having an internal actuator configured to cause fluid flow to exit the tip portion through the fluid path at a predetermined pressure level when the internal actuator is actuated, the tip portion including one or more apertures on a distal portion, an inner chamber and an extruding portion of an inner component that is disposed in the inner chamber forming a circumferential fluid canal, the circumferential fluid canal defined by a clearance between the inner chamber and the extruding portion of the inner component, wherein the extruding portion of the inner component is a tapered cylinder that is wider at the distal portion and includes a tip cavity at a proximate portion, wherein fluid flow from the body cavity is directed into the circumferential fluid canal, filing the tip cavity and the circumferential fluid canal so as to reduce pressure of fluid exiting the apertures.
