DISPOSABLE UNIT DOSE DISPENSER FOR POWDERED MEDICANTS.

摘要

A disposable unit dose dispenser is provided for fluidizing and dispensing a predetermined quantity of powdered product, such as an antihistamine or a decongestant. The dispenser includes a first layer and a second layer connected together to form a gas chamber and a product reservoir adjacent one another. The product reservoir includes a delivery tube adapted to dispense the powdered product. The dispenser also includes a seal which separates the gas chamber from the product reservoir such that when pressure is applied to the gas chamber by squeezing the dispenser the seal ruptures causing a jet of gas to discharge from the gas chamber into the adjacent product reservoir fluidizing and dispensing substantially all of the powdered product from the product reservoir through the delivery tube.
