The body (10) is dimensioned to accommodate an ampoule head (11) and an inwardly-directed annular bead (12) is provided at said open end against which the neck of an ampoule can be broken. A cutter (17) protrudes from said bead (12). The bead (12) is provided at the convergence of an outwardly-directed peripheral flange (14) and an inwardly-directed annular ramp (19). A plunger (18) whose piston (18B) is hollow is provided in the body (10) to eject broken ampoule heads (11).</p> |
