1. A flap closure comprising:
a closure body and a flap cover which are connected to one another by at least one hinge and by at least one tensioning band in order to achieve a snap-effect upon an opening and/or closing of the flap cover,
wherein a distance from a tangent at a center line between at least two edges of the at least one tensioning band at a connection point of the at least one tensioning band with the closure body and/or from a tangent at a center line between the at least two edges of the at least one tensioning band at a connection point of the at least one tensioning band with the flap cover to an axis of rotation of the at least one hinge is at most two times a thickness of the at least one tensioning band at the respective connection point in a cross section perpendicular to the axis of rotation of the at least one hinge in an unloaded state of the at least one tensioning band.
