This invention relates to a pressure top (1) which is suitable to be placed on beverage-containing vessels for pressurizing. The pressure top solves the problem of making available an improved device for providing pressure for beverage-containing vessels. It comprises a extractor blade (2) which is in operative connection with a gas cartridge via a valve arrangement, wherein the gas cartridge is displaceably provided by means of a lever arrangement (4) against a spike (5) which in turn is provided on a carriage (6): It rests against a plunger (8) which is displaceable in a recess (7). A sealing element is on one end of the plunger (8) facing the spike (5). The plunger (8) is displaceably provided in a bearing shell (10) and is in operative connection with a first end of an actuating lever (11). The carriage (6) has a bore (12) on which a first channel (14) provided in a bridge part (13) is bordering and which creates a fluidic connection between a piston (16) and the bore (12). The piston (16) rests against a second end of the actuating lever (11) tiltably supported in the cap; said lever encloses the space (17) which is in fluidic connection with the extractor blade (2) via a second channel (18).
