<p><P>PROBLEM TO BE SOLVED: To provide a top plate cover for a kitchen stove which is excellent in shape retainability, allows a cut line as an opening assisting line to be easily formed, and is efficiently installed for each gas burner. <P>SOLUTION: A disc-like sheet body 11 of a top plate cover 10 comprises a nonflammable paper 51, and first aluminum foil 53 and a second aluminum foil 55 pasted on both surfaces of the nonflammable paper 51. Since both surfaces of the nonflammable paper 51 are covered with the first aluminum foil 53 and the second aluminum foil 55 which shape retainability, the shape retainability of the sheet body 11 is improved. Concentric cut lines 21 for forming an opening corresponding to various gas burners are continuously formed on the second aluminum foil 55 located on the lower surface side of the sheet body 11 and a part of the nonflammable paper 51. When the cut line 21 is formed with a Thomson blade, the tip position is provided with a tolerance by 1/2 of thickness T<SB POS="POST">1</SB>of the nonflammable paper 51 at upper and lower parts. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
