The nozzle (2) has a piston member (5) extending inwardly from an outlet opening (9), the piston member having at least one discharge channel. A container (10) of the substance to be discharged is mounted on the piston member (5), and a seal (12) is arranged across the container (10) to seal in all the substances to be discharged. The piston member (5) has a piercing member (8) which extends towards the seal (12), whereby on pressing the container (10) on to the piston member (5) the seal (12) is pierced to allow the contents of the container (10) to be expelled along the discharge channel and out through the outlet opening (9). <IMAGE> |
