Abstract
The present invention provides a particulate delivery device with an automatic activation mechanism that pierces or cuts a composition capsule when a cap is removed. The cap cannot be replaced once the device is activated for use. The device allows for gas flow through the device from a gas inlet to a gas outlet through a composition receptacle and dispersion chamber to deliver particulate to the airway of a subject.
