Patent

CA 2643566

It is intended to provide a skin patch coated with a stripping film which can be unconsciously and easily stripped off without lowering the adhesive force of the patch. Namely, a skin patch for external use characterized by comprising a support, a water-containing ointment which has a pressure-sensitive adhesiveness and is spread almost all over one face of the support and a stripping film which is bonded to the ointment and in a size larger than the ointment face, wherein the stripping film, which is bonded to the ointment and in a size larger than the ointment face, has projections which are raised on the ointment face and not bonded to the ointment, or loosened parts which are raised upward at arbitrary sites of the ointment face and not bonded to the ointment.

La présente invention vise à proposer un timbre cutané revêtu d'un film pelliculable qui peut être inconsciemment et facilement décollé sans réduire la force adhésive du timbre. A savoir, elle concerne un timbre cutané destiné à une utilisation externe et caractérisé en ce qu'il comprend un support, un onguent contenant de l'eau qui présente une adhésivité sensible à la pression et est étalé sur pratiquement toute une face du support et un film pelliculable qui est lié à l'onguent et d'une taille plus grande que la face à onguent. Ledit film comporte des saillies qui se dressent sur la face à onguent et qui n'y sont pas liées, ou des parties lâches qui se dressent vers le haut au niveau de sites arbitraires de la face à onguent et ne sont pas liées à l'onguent.
