The closure element also includes a plurality of closure legs extending from the second sealing surface that define a plurality of side vents between each of the closure legs when the container closure system is in the open position. The length, thickness, number, and shape of the legs are chosen to produce an effective total side vent area that is at least 50% of the area of the container opening. Alternatively, the length, thickness, number, and shape of the legs are chosen to produce an effective total side vent area that is greater than the cumulative surface area of the outwardly facing surface of the closure legs. | 01-01-2009 |
