Disposable toilet hygienic seat cover and laying method thereof

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. Also disclosed is a method for laying the disposable toilet hygienic seat cover.
