Abstract
The present invention provides an inhalation device for use with a pressurized container having an outlet valve mechanism and from which material may be discharged by depression of a portion of the valve mechanism thereof, which device comprises a chamber for receiving said container; actuating means adapted to bear on the valve mechanism of the container; and first and second biasing means both adapted to bias the container towards the actuating means, said first and second biasing means each being of insufficient force alone to depress the portion of the valve mechanism of the container but together being of sufficient force to do so, said second biasing means being restrained in a position in which it does not bear on the container and releasable on inhalation through the device to a position in which it does bear on the container.

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.
