The covering panel (1) consisting, for example, of cardboard is provided with notch lines (8-11) on the two surfaces (4, 7) facing away from one another, adjacent notch lines (8, 10 or 9, 11) of the two surfaces (4, 7) form an intended tearing point for manually pressing the covering panel (1) through. These adjacent notch lines (8, 10 or 9, 11) are offset relative to one another, transversely to their extent. The covering panel material serves as the intended tearing point between the mutually offset notch lines (8, 10 or 9, 11), that is to say specified by the size of the offset. This can be changed empirically depending on the covering panel material in order to achieve the pressing-through by hand. As a result, the difficult production of the depth of the notch lines (8-11) is avoided. Additionally, the size of the offset can be greater than the thickness of the covering panel. An effective barrier is achieved, for example when packaging products which are sensitive to moisture or have an intense odour. <IMAGE>
