A flexible diffuser membrane is provided with a unique system of perforations arranged to result in uniform distribution of gas even though the membrane deflects to different extents or the submergence varies in different parts of the membrane. The perforations are arranged to provide less perforation area per unit of perforated membrane surface area in the membrane parts that deflect the most or are submerged least and greater perforation area in membrane parts that deflect the least or are submerged most. The perforations can be slits arranged in parallel rows on a tubular membrane, in concentric circles or another pattern on a disk membrane, or in still a different pattern on a flat panel diffuser membrane. The slit length or separation can be varied between different zones on the membrane surface or the spacing between rows or circles can be varied.

A rupturable closure for use with a flexible container that is especially suited for pouring viscous fluids such as motor oil. The closure is secured to the pouring spout or other dispensing opening of the container and retains the viscous fluid in the container as the container is brought into inverted position for pouring. Notwithstanding the ability of the closure to hold in the viscous fluid, the closure also allows the closure to breathe when the cap is removed so as to relieve small variations in pressure as the flexible container is first grasped for pouring and thereby prevent premature rupture of the closure before or as the container is inverted for pouring. Such a closure includes a membrane secured over the dispensing opening of the container. The membrane has a small primary vent orifice in the region over the dispensing opening that is sized to permit the membrane to breathe. The membrane also has three or more part lines terminating in the primary vent orifice along which the membrane parts when the flexible bottle is squeezed.
