<p>A disc-like cover for frying pans or like vessels, having a steam-permeable filter surface made of fibrous filter element is shaped to be produced very simply and as a disposable item can be easily destroyed after a single use. According to the invention the steam-permeable areas of the filter are delimited at least in part by thickened areas within the filter material these thickened areas, interlocked with the filter, have plastic additions, the pores of the filter serve especially as locking cavities for the addition. These thickened areas are stiffer than the steam-permeable areas and thus render the disc-like cover as a whole more stable with regard to shape. In addition, conventional radial arms of one width are weakened in cross-section by cuts that extend from one of their edges and the adhesive joint between the radial arm and filter surface is reduced in the area of weaker cross-section. At least two cuts are made in each radial arm, each extending from one edge, all the cuts being parallel.</p> |
