  • Patent number: 4887321
    Abstract: A novel toilet seat cover is provided herein. The cover comprises a water-impermeable, very light weight, easily disposible paper, the paper being in the form of a porous paper coated only on the reverse side thereof which is adapted to face the toilet bowl with a water-repellent material, thereby retaining a porous paper surface for contact with the user while rendering the paper as a whole water impermeable and non-porous, the paper being provided with a single central straight line longitudinal slit opening or a perforation or line of weakness. The toilet seat cover is folded longitudinally along the slit or perforation and then is folded transversely in a zig-zag or back-and-forth accordion-type fold to be folded at least for the region of the slit or perforation. The toilet seat cover, when in use, is adapted to be placed over the toilet seat and to have its peripheral edges folded under the toilet seat to be retained thereby.
