Abstract: A disposable sanitary toilet seat cover of the type capable of being flushed in the toilet and comprising a foil or paper sheet provided with a round-going weakening line dividing the cover into a central field and an annular field, the latter serving to protect the user from contact with the toilet seat. The toilet seat cover can be handled with particular ease and speed if the annular field is fixed to the toilet seat by means of a pressure adhesive, and in order to achieve safe protection against the transfer of contagious matter from the toilet bowl the central field is constructed with an additional weakening line which divides the central field into two field portions, one of which can depend into the toilet bowl, while the other field portion can be used as toilet paper.
