Abstract
Abstract The specification discloses a wound dressing or like applique including an adhesively coated upper layer backed by a release liner wherein the upper layer is perforated and the release liner is cut, there also being a slit extending through both the release liner and the upper layer from the peripheral edge of the article to the perforation and cut lines in the respective upper layer and release liner. This facilitates removal of the offal portion from that portion of the upper layer which is to be adhered to a wound or other surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
191 words
A wound covering or like applique including an adhesive coated upper layer and a release liner covering said adhesive, there being a perforation line in said upper layer to define a central portion which is to be applied to a surface and a generally comparable cut line in the release liner to define a central portion of release liner generally covering said central portion of said upper layer, the improvement comprising: a slit in said upper layer extending from the periphery thereof to said perforation line and a slit in said release liner, in alignment with said slit in said upper layer, and extending from the periphery of said release liner to said cut line, whereby said central portion of said release liner can be peeled away from said central portion of said upper layer, said upper layer applied to the desired surface and said offal portions of said release liner and said upper layer readily peeled away by grasping said offal portions at a point generally adjacent said slit lines and pulling said offal portions away from said central portion of said upper layer to thereby break said perforation line.
Claim 2
Dependent Claim
