Title:
CLOSURE DEVICE PROVIDING VISUAL CONFIRMATION OF OCCLUSION
Document Type and Number:
WIPO Patent Application WO/2005/108224
Kind Code:
A3
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 location 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.
