The cartridge has a lateral wall (2b) that is deformable under pressure exerted by the driving piston. The cartridge has a central hollow projection (2d) and an obturator (2e) that permits communication between an inner side of the cartridge and an injection liquid dispensing pipe (3). The body has a removable part i.e. cover (9b), for placing and removing the cartridge. An independent claim is also included for a method for fabricating a disposable and hermetic cartridge.</p> |
