A membrane puncturing mechanism (2) comprises a first element (16) and a second element (14) arranged with opposing surfaces (46, 48). At least one opposing surface (46, 48) comprises a sloping region (50, 52) inclined relative to the other opposing surface (46, 48). The first element (16) is moveable towards and away from the second element (14). A pin (10) for puncturing a membrane (6) is coupled to the first element (16) such that movement of one of the pin (10) and first element (16) causes movement of both. A spring (12) is operable to bias the first element (16) towards the second element (14). An actuator (18) is removably positioned between the opposing surfaces (46, 48), the actuator being withdrawable from between and moveable along the opposing surfaces (46, 48) such that, as the actuator (18) is withdrawn, the actuator (18) progressively moves the first and second elements (16, 14) apart against the bias of the spring (12) so as to load the spring (12) and such that the actuator (18) being fully withdrawn from between the opposing surfaces (46, 48) allows the first element (16) to move towards the second element (14) under the load of the spring (12) thereby moving the pin (10) for puncturing the membrane (6).
