ABSTRACT:
A closure device providing a visual confirmation of occlusion. The closure device includes a first and a second interlocking fastening strips which are arranged to be interlocked over a predetermined length, at least one of the fastening strips having a surface alteration providing visual confirmation of occlusion of the closure device. The surface alteration may be a slit which opens or closes upon occlusion of said closure device. In one embodiment, the surface alteration may extend into a coextruded portion. The color of the coextruded portion is exposed when the surface alteration is open and hidden when the surface alteration is substantially closed. In another embodiment, the surface alteration may extend into an edge glow material which produces an edge glow effect when the surface alteration is open. In a third embodiment, the surface alteration may extend through an opaque side wall to expose the color of the base. The surface alteration may be located on the mating side, the non-mating side or both sides of one or both of the bases. In addition, the surface alteration may be located on the closure element. The opening or closing of the surface alteration may be achieved by a deformation in the closure device upon occlusion of the closure device. The deformation may be an inward deformation or an outward deformation on the fastening strip. This deformation may also allow a user to tactually confirm that the closure device has been occluded, even after the closure device has been occluded. The deformation may be on one or both of the fastening strips. In addition, the fastening strip may include multiple deformations.
