<P>PROBLEM TO BE SOLVED: To provide a tea filtering plastic net which can deal with tea pots in different sizes and has a lid removal preventing function. <P>SOLUTION: An extension function to adjust a size of a tea filter is added to the tea filter attached under a tea pot lid. A bag made by sewing a flexible thin heat resistant nylon net 5 into a Kinchaku (Japanese one side string tightened bag shape purse) shape is used for the net part of the tea filter. A shape memory wire 2 with circumference adjusting function is used instead of the string to fasten the Kinchaku. This net can be used for a tea pot with a lid removal preventing function. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
