Abstract
An apparatus for dispensing pharmaceutical articles includes a housing and a gas source to provide a positive pressure supply gas flow. The housing defines a hopper chamber to hold the articles, a dispensing channel fluidly connected to the hopper chamber, a drive jet outlet, and an agitation outlet. The dispensing channel has an inlet and an outlet and defines a flow path therebetween. The gas source is fluidly connected to each of the drive jet outlet and the agitation outlet to provide: a pressurized drive jet gas flow through the drive jet outlet to convey articles through the dispensing channel along the flow path; and a pressurized agitation gas flow through the agitation outlet to agitate articles in the hopper chamber.
