Abstract
A drug dispensing device is comprised of an upper hopper having an upper opening for receiving a medicament and a lower opening. A lid covers the upper opening. A lower hopper having an upper opening and a lower opening in a bottom portion thereof is provided. The upper hopper defines a bulk storage chamber and the lower hopper defines a dispensing chamber. A rotatable dispensing disc is positioned in a lower portion of the dispensing chamber for dispensing medicament from the drug dispensing device through the lower opening in the lower hopper. A regulator is situated between the bulk storage chamber and the dispensing chamber for controlling the rate at which medicament moves from the storage chamber to the dispensing chamber. The regulator may take a variety of forms. In one embodiment, the regulator includes a valve for controlling the flow of medicament from the storage chamber to the dispensing chamber. The valve may include a member responsive to the volume of medicament in the dispensing chamber for controlling the position of the valve. The valve and member may include a trap door valve and a float, a butterfly valve and a rotatable arm, a guillotine valve and a movable arm, and a conical plunger and a wing extending from the base of the plunger. In another embodiment, the regulator may include a rotatable member having an opening therein. The rotatable member may include a cylindrical wall having an opening in a portion thereof, a plate having an opening therein, a cup shaped member defining an opening and a pair of rotatable members which together define at least one opening therein. The regulator may be configured such that the rate at which medicament moves from the storage chamber to the dispensing chamber is never zero. Further, agitating members may be provided which extend toward the upper hopper. Methods of operation are also disclosed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
