Abstract:
A tamper evident label flap positionable to cover an opening in a package containing removable articles, the label flap comprising:a base layer sized to cover the opening in the package, the base layer having a top surface and a bottom surface, the bottom surface including a first adhesive to permit removal and application of the label flap to the package; a tamper indicating tab formed in the base layer, the tamper indicating tab being defined by a weakened portion of the base layer, the tamper indicating tab including the first adhesive on its bottom surface; a discontinuous first ink layer applied to the top surface of the tamper indicating tab to define an indicia; a second ink layer applied over the entire tamper indicating tab including the first ink layer, the second ink layer contacting the top surface of the tamper indicating tab in areas not covered by the first ink layer, wherein the second ink layer extends past the weakened portion of the base layer defining the tamper indicating tab; and a transparent top layer adhesively attached to the entire base layer including the second ink layer applied over the tamper indicating tab, the second ink layer forming a substantially stronger bond to the top layer than the first ink layer and the second ink layer forming a stronger bond to the base layer than the top layer, wherein when the label flap is pulled from the package, the tamper indicating tab separates from the base layer and remains in contact with the package and the areas of the second ink layer applied over the first ink layer separate from the first ink layer and remain in contact with the transparent top layer such that the indicia defined by the first ink layer is visible on the tamper indicating tab.
