Abstract

An adsorbing element for adsorbing and releasing a gas includes a plurality of adsorbing sheets. Each adsorbing sheet includes gas-permeable sheets such as non-woven fabrics or filter papers, and an adsorbing material filled between the gas-permeable sheets. First and second supporting members are provided such that each of them is formed of a paper-like sheet formed with a plurality of pleats which have straight trough lines. Each of the pleats of the first supporting member is located facing and spaced from each of the pleats of the second supporting member to form a pair of the facing pleats, defining a pair of facing trough portions. In this adsorbing element, the first and second side edges of each adsorbing sheet are located respectively at the pair of facing trough portions so that each adsorbing sheet is supported between the pair of the facing trough portions.

Claims4

Dependent claims

An adsorbing element comprising:

a plurality of adsorbing sheets, each adsorbing sheet including gas-permeable sheets selected from the group consisting of non-woven fabrics and filter papers, and an adsorbing material filled between the gas-permeable sheets, each adsorbing sheet being formed sheet-like and having first and second side edges which are straight and located at opposite sides of the adsorbing sheet;
and
first and second supporting members each of which is formed of a paper-like sheet formed with a plurality of pleats each of which is formed by folding the paper-like sheet at a flat state, the pleats having straight trough lines, each of the pleats of the first supporting member being located facing and spaced from one of the pleats of the second supporting member to form a pair of facing pleats, each pair of facing pleats defining a pair of facing trough portions,
wherein the first and second side edges of each adsorbing sheet are located respectively at one pair of facing trough portions so that each adsorbing sheet is supported between its respective pair of facing trough portions.
