Abstract
A releasable fastening features a first fastening strip including an elongated, flexible base carrying an array of discrete fastener elements arranged in rows and columns, and a second fastening strip configured to releasably engage with the first fastening strip. The first fastening strip also includes a longitudinally continuous rib supported by the upper surface of the base of the first fastening strip, the rib extending sufficiently far from the base of the first fastening strip to engage a sealing portion of the second fastening strip, and of a bending strength sufficiently low that the rib is placed in an elastically bent state, when the first and second fastening strips are in the engaged state, thereby forming with the sealing portion of the second fastening strip a non-interlocking barrier to resist flow across the fastening with the first and second fastening strips in the engaged state.
