  • Adhesive dressing for easy application to skin
    Patent number: 4815457
    Abstract: The present invention relates to an adhesive dressing 1, coated on one surface with a pressure-sensitive adhesive 3 and covered with a non-adhesive support 4. The dressing 1 is folded back on itself on the side of the protective support 4 along a transverse fold 5, to give two parts 1a and 1b. The protective support 4a of one of the two parts 1a is cut along a line 6 parallel to the fold 5. Area 7 of the support between the cut 6 and the fold 5 is provided with an adhesive 8 such that the said area 7 adheres more strongly to the corresponding area of the other part of the support 4b than to the plastic film 2. This invention facilitates application of the dressing to skin.
