Abstract
A moisture-resistant fastener, which may be incorporated as part of a bag, pouch, wrapper, or liner, or which may be used as a protective garment closure, includes a pair of flexible closure strips. The strips include interlocking ribs and channels of complementary cross-sectional shape which lock together in an interference fit. The ribs have enlarged heads, and, complementarily, the channels have enlarged bottoms. At least one of the enlarged heads and enlarged bottoms has an integrally formed longitudinal gasket of a polymeric material softer than that used to extrude the flexible closure strips. When the flexible closure strips are locked together by forcing the ribs of one into the channels of the other to establish the interference fit, the longitudinal gasket is compressed and forms a moisture-resistant seal having an effectiveness heretofore not available or achievable.
