Apparatus for discharging a pressurised container (61) in which a hollow body (10) has internal bore means (20, 25) and in which closure opening means, e.g. a hollow pin (53) is mounted on piston means (15) slidably located in part of the bore means, e.g. in a piston cylinder (25); there being a passage (150) which extends from the pin to the opposite side of the piston means so that the initial release of gas passes through the piston means and drives the piston means towards the container to sealingly clamp sealing abutment means (54) against the end of the container around the pierced closure (64) of the container. |
