Patent ID: 8287566

Claim:
A spray device for dispensing droplets of a viscous fluid, comprising: a housing defining an interior space to receive a supply of a propellant fluid and a supply of a viscous fluid; a first container arranged in a portion of the housing to maintain the supply of the viscous fluid in isolation from propellant fluid, wherein the first container comprises: an exit port through which the viscous fluid is adapted to exit, a movable plunger device in an interior space of the first container that is biased toward the viscous fluid, and a least a second port positioned on the first container so as to face a different direction than the exit port; and a nozzle device to spray droplets of the viscous fluid toward a targeted site, the nozzle device being fixedly coupled to the portion of the housing that receives the first container and being in fluid communication with the first container in the housing such that the viscous fluid interacts with the propellant fluid only after exiting the nozzle device.
