The appliance also includes a damper valve to allow the user to exhale through the appliance prior to attempting to inhale with the damper valve being positioned to be opened by the regulating bottle sliding in the appliance. Another form of the invention includes a runner which receives the regulating bottle with the runner serving to activate the regulating bottle to release the dose of the active element therefrom. The valve includes, in one form of the invention, at least one slot in the body of the appliance and one slot in the runner which slots may be brought into registry to allow the user to inhale.
