<p>A device for opening ampoules comprises a hollow cylindrical body, the peripheral wall of which has slits forming two halves which can flex relatively apart or together at an open end of said body to enable entry of an ampoule head portion and for ejection of a broken head portion respectively. The body is dimensioned to accommodate an ampoule head and an inwardly-directed annular bead is provided at the open end against which the neck of an ampoule can be broken. A cutter protrudes from the bead. The head is provided at the convergence of an outwardly-directed peripheral flange and an inwardly-directed annular ramp. A plunger whose piston is hollow is provided in the body to eject broken ampoule heads.</p> |
