Abstract
A canister includes a main casing, a first port formed in a wall of the main casing, and a first adsorbent section within the main casing. The first adsorbent section and the wall of the main casing define a space section therebetween. The first adsorbent section includes a first adsorbent and a first retainer holding the first adsorbent. The canister also includes a first elastic element disposed in the space section. The first elastic element urges the first retainer to elastically hold the first adsorbent. In addition, the canister includes a subcasing integral to the wall of the main casing. The subcasing is positioned within the space section. Further, the canister includes a second adsorbent section in communication with the first port. The second adsorbent section includes a second adsorbent disposed within the subcasing. Still further, the canister includes a second retainer holding the second adsorbent.
