<p><P>PROBLEM TO BE SOLVED: To provide an adsorbing element 1 of simple structure with a low ventilation resistance without finely folding an adsorbing sheet 2 with an adsorbent material packed therein. <P>SOLUTION: This adsorbing element 1 is provided with a plurality of the rectangular adsorbing sheets 2 in which particulate activated carbon is packed between both faces of nonwoven fabrics or paper sheets, and holding members 3 constituted of pairs of paper sheets 3A, 3B formed by folding back a plurality of pleats. The adsorbing sheet 2 is held in valley parts 11 of the oppositely disposed pleats, and held in a laminated state across a space 15 (processes (d), (e)). The one obtained by combining the absorbing sheets 2 and the holding members 3 are inserted into a square cylinder-like casing while being compressed, to complete the cartridge-like adsorbing element 1. Air containing odorous components flows through the spaces 15, and the odorous components are adsorbed during this process. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
