An apparatus for evacuating a bottle which is fitted with a sealing cap (60) which has a bore housing a displaceable plug (62). The apparatus comprises a platform on which to stand the bottle, and a plunger (34) directed towards the platform. Actuating means (e.g. a manually operable lever) serve firstly to extend the plunger (34) (together with an assembly (40-52) in which it is mounted) and push the plug (62) from a first, sealing position within the cap to a second, non-sealing position, then to apply suction through the plunger (34) to evacuate the bottle via the cap bore, and finally to extend the plunger (34) further (displacing relative to assembly 40-52) to push the plug into a third, sealing position within the cap. |
