Abstract

A sticker includes a backing layer, a sticker body including a top layer and an adhesive layer, and a security arrangement cutting through the top layer only and being stopped at an adhesive layer to ensure the sticker body being completely removed from the backing layer without tearing the top layer apart. The security arrangement includes a plurality of lead edge notches evenly provided along the outer flange of the top layer, and a cutting line structure formed at the top layer. After the sticker body is completely removed from the backing layer and is applied for sticking on an object surface, the sticker body becomes a self-destructive layer by the security arrangement to be torn apart at the time when the sticker body is removed from the object surface so as to ensure the sticker body being unable to be removed completely from the object surface.

Claims

1. A sticker, comprising:

a backing layer;

a sticker body, which comprises an adhesive layer detachably retained on said backing layer and a top layer overlapping on said adhesive layer, wherein said top layer has a center jointing zone and an outer flange; and

a security arrangement, which cuts at said top layer of said sticker body that said security arrangement cuts through said top layer only and stops at said adhesive layer to ensure said sticker body being completely removed from said backing layer without tearing said top layer apart, wherein said security arrangement comprises;

a plurality of lead edge notches provided along said outer flange of said top layer towards said center jointing zone thereof for lead splitting and tearing said top layer; and

a cutting line structure formed at said top layer between said outer flange and said center jointing zone in such a manner that after said sticker body is completely removed from said backing layer and is applied for sticking on an object surface, said sticker body becomes a self-destructive layer by said security arrangement to be torn apart at the time when said sticker body is removed from said object surface so as to ensure said sticker body being unable to be removed completely from said object surface wherein said cutting line structure comprises a guide cut structure provided at said top layer for splitting said top layer once said sticker body is attempted for being peeled from said object surface, wherein said guide cut structure is extended from said center jointing zone towards said outer flange at a position that said guide cut structure is aligned with each of said lead edge notches.

2. The sticker, as recited in claim 1, wherein said guide cut structure comprises a plurality of main guide cuts extended from said center jointing zone towards said outer flange, and a plurality of supporting guide cuts alternating with said main guide cuts, wherein a length of each of said main guide cuts is longer than a length of each of said supporting guide cuts.

3. The sticker, as recited in claim 2, wherein said guide cut structure further comprises a plurality of dotted guide cuts randomly formed at said top layer and extended from said outer flange at a position that said dotted guide cuts are aligned between two neighboring lead edge notches.

4. The sticker, as recited in claim 2, wherein said cutting line structure further comprises a plurality of starburst cuts provided at said top layer at a position that each of said starburst cuts is intersected with one of said main guide cuts and said supporting guide cuts for easily separation said top layer from said backing layer without damage or splitting said top layer while removing said sticker body from said backing layer, wherein each of said starburst cuts is arrow shaped and selectively pointing at one or more of said respective lead edge notches.

5. The sticker, as recited in claim 2, wherein said sticker body has a circular shape that said main guide cuts and said supporting guide cuts are radially extended from said center jointing zone towards said outer flange.
