Flat laminate part consisting of a substrate layer, a cover layer and an auxiliary pull-off means for the cover layer

A flat laminate part comprising:

• a flexible substrate layer having at least one surface;
• a cover layer at least partially on the one surface of said substrate layer;
• means for effecting adhesion of said cover layer to said surface of the substrate layer in the area of said cover layer such that the layers are securely held together but may be pulled apart;
• a substantially continuous cut or preset breaking line in said cover layer from one edge to another edge of said cover layer thereby separating the cover layer into two parts, at least parts of said cut or preset breaking line respectively diverting substantially from a straight connection line between the end points of the cut at the edges of the cover layer into each part of said cover layer to define the locations of grasp parts;
• and
• stiffened areas in said cover layer surrounding said cut or preset breaking line and including at least the grasp part locations defined within said diverting parts of said cut or preset breaking line;
• the stiffness of said stiffened areas and the adhesion between said substrate layer and said cover layer being such that, upon bending of the flat laminate part substantially along said straight connection line between the end points of said cut at the edges of said cover layer in a direction which produces a convex curvature of the exposed surface convexly on the side of the cover layer, said diverting parts of said cut or preset breaking line into each part of the cover layer are separated and peeled off from the substrate layer to thereby expose the grasp parts.
