Title: Needleless injector drug capsule and filling method

Abstract: A needleless injector capsule for a liquid medicament has a filling adaptor removably, and preferably frangibly, attached thereto. The capsule has a chamber for receiving injectate, the chamber being provided with an injection orifice, and having a piston located for movement therein. The adaptor has a bore which communicates with the capsule chamber via the injection orifice. The capsule is filled by introducing injectate into the capsule chamber through the injection orifice and excess injectate into bore of the adaptor, and closing the bore of the adaptor to the exterior by a sealing means, leaving the bore partly filled with excess injectate.
