A bottle cap for the introduction of pressure into a bottle, in which the bottle cap has a cap body configured with a through opening; and a one-way valve arrangement having at least one flexible valve component configured either with a through slit, such that the through slit is aligned with the through opening and an association between the cap body and the one-way valve arrangement maintains a planer profile of the flexible valve component after introduction of pressure into the bottle, or a flap valve integrally formed with the cap body, so as to prevent escape of pressurized gases from the bottle. |
