ABSTRACT:
A dispenser comprising a container and a mouthpiece is adapted to deliver a volatilizable liquid orally to the user. A volatilizing chamber is defined between the liquid reservoir in the container and the drawing passage in the mouthpiece through which the user inhales. A permeable fluid barrier separates the liquid in the reservoir from the open pore material which fills the volatilizing chamber and limits the amount of liquid which can be aspirated through the open pore material to the user. A vent passage in parallel with the fluid barrier when uncovered and open allows air to be drawn through the open pore material to volatilize any liquid retained thereon. When covered and closed, the vent passage allows liquid to be aspirated from the reservoir through the permeable fluid barrier, the volatilizing chamber, and the mouth piece and into the user's mouth.
