<p>A needleless injector capsule (1) has an adaptor (2) for use in filling the capsule. The capsule defines a chamber which is for receiving injectate and is provided with an injection orifice (5), a piston (3) being located for movement within the chamber. The adaptor is removably connected to the capsule and has a bore which communicates with the capsule chamber via the injection orifice (5). The adaptor bore has a first portion (15) of smaller cross-section adjacent the injection orifice and a second portion (9) of larger cross-section remote from the injection orifice. <IMAGE></p> |
