<p><P>PROBLEM TO BE SOLVED: To make a head cover for use in a dental headrest inexpensive by using a paper sheet as the head cover; to enable many cover sheets to be detachably attached to the rear side of the headrest in a bundled state; to facilitate cover replacement work by replacing the head cover with the new one in such a manner that the head covers are torn off one by one every day; and to sanitarily replace the head cover by employing a disposable type. <P>SOLUTION: The head covers 10 are constituted as a paper pad which is obtained by bundling one-side edges of many pieces 10<SB>1</SB>-10<SB>n</SB>of paper. The bundled-side edge 10a is detachably prefixed to the back side of the headrest 9 of a dental care chair 1. The many pieces 10<SB>1</SB>-10<SB>n</SB>of paper are turned over one by one and laid on the front side of the headrest 9, so as to serve as the head cover. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
