    • A closure device having first and second fastening strips arranged to be interlocked over a predetermined length is provided. Each of said first and second fastening strips includes first and second closure elements separated by an intermediate area, wherein the first closure element on the first fastening strip is arranged to be interlocked over a predetermined length with the first closure element on the second fastening strip, and the second closure element on the first fastening strip is arranged to be interlocked over a predetermined length with the second closure element on the second fastening strip. Each of the closure elements may be colored with a colorant. For example, the closure elements on one fastening strip may be colored with an opaque pigment, and the intermediate area on that fastening strip may colored with a first translucent pigment. The closure elements on the other fastening strip may be colored with a translucent pigment, and the intermediate area on that fastening strip may be colored with a second opaque pigment. When the closure device is occluded, the colors of the first and second pigments combine to cause a change in color. The change in color may be observed from either side of the closure device.
    • 提供具有布置成在预定长度上互锁的第一和第二紧固条的封闭装置。 所述第一和第二紧固条中的每一个包括由中间区域隔开的第一和第二封闭元件,其中第一紧固条上的第一封闭元件布置成与第一封闭元件互锁在预定长度上, 并且第一紧固带上的第二闭合元件布置成与第二紧固带上的第二闭合元件互锁在预定长度上。 每个封闭元件可以用着色剂着色。 例如,一个紧固条上的封闭元件可以用不透明颜料着色,并且该紧固条上的中间区域可以用第一半透明颜料着色。 另一个紧固条上的封闭元件可以用半透明颜料着色,并且该紧固条上的中间区域可以用第二不透明颜料着色。 当封闭装置闭塞时,第一和第二颜料的颜色结合起来导致颜色变化。 可以从封闭装置的任一侧观察到颜色的变化。

    • 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.
