Abstract
An inhaler for powder products comprising a housing having an oral suction mouthpiece, a piston contained within the housing for movement in opposite directions, and an elastic member for urging the piston in one direction. The mouthpiece connects with a chamber in which the piston is located so that inhaling through the mouthpiece draws the piston toward the user's mouth. The piston includes a charging cavity for holding a charge of powder product. The cavity communicates with the internal volume of the mouthpiece as the piston is drawn toward the user's mouth whereby the charge is dispensed and inhaled by the user.
