  • Semipermeable venting closure
    Patent number: 6274209
    Abstract: A venting cap (1) has a cavity (7), at least one first passage (4) for fluids connecting the cavity (7) with the inside of the container, at least one second passage (5.1, 5.2, 5) for fluids connecting the cavity (7) with the outside of the container, and a liquid-absorbing mass (8) arranged within the cavity (7). The liquid-absorbing mass (8) acts, after absorption of liquid, as a selective filter prohibiting the passage of liquid, but permits the passage of gas. This ensures the foolproof selective permeation of gas but not of liquid. Venting properties remain unaltered even at extreme conditions of transportation and storage.
