20120145847 | HOOK - A hook comprises an adhesive body and a hook body attached to the adhesive body, where the adhesive body comprises a base layer and an adhesive layer. The adhesive layer is a thermoplastic elastomer with an intrinsic adhesion. The hook body and the adhesive layer are respectively attached to two opposite surfaces of the base layer. The hook includes a base layer interposed between the hook body and the adhesive layer, so that the hook body is not directly attached to the adhesive layer. While in use, the adhesive layer isn't directly pulled by the object, thus the adhesive layer has prolonged service life and enhanced adhesive intensity. Besides, through setting the base layer, the hook has better tenacity, and various needed patterns, colors or textures are easily printed on the base layer. | 06-14-2012 |
