Abstract
A tubular toilet seat cover is stored on a reel and pulled off from this reel as it is replaced, and the used cover is taken up on another reel. By actuating a drive mechanism, the cover is moved through a predetermined distance in such manner that when it is in the mounted position, the toilet seat body is surrounded by the tubular cover and the cover covers the important part of the toilet seat. The toilet seat, drive mechanism and storage device constitute a structural unit which is mountable as a whole on a conventional toilet seat, or it may constitute a unit with a toilet seat.
