  • Publication number: 20140317837
    Abstract: A disposable toilet hygienic seat cover is suitable for being laid on a toilet seat (11) having a toilet seat cover (12), and mainly consists of a seat cover ring sheet (20), a covering sheet (30), a covering concave portion (40), and a positioning unit (50). The disposable toilet hygienic seat cover has a covering concave portion (40) that covers a front portion (121) of the toilet seat cover and a front portion (111) of the toilet seat. Therefore, the covering sheet (30) for defining the covering concave portion (40) can also cover and be positioned at the front portion (121) of the toilet seat cover and the front portion (111) of the toilet seat. Hence, the covering sheet (30) does not move randomly, thus preventing the skin, trousers, or skirt of a toilet user from contacting the front portion (121) of the toilet seat cover or the external surface of the front portion (111) of the toilet seat, thereby ensuring hygienic toilet using and solving the problem of bacterial infection.
