A container for particulate desiccant includes a cup and a cap. The cup includes spaced inner and outer wall portions connected by a transverse web portion to define a chamber having an opening for receiving the desiccant. The chamber side of the transverse web includes peripheral and central flanges, or energy directors, to which a first ply of permeable lining material is ultrasonically bonded. The cap is designed for receipt in the chamber to cover the opening. In addition, the cap has a hole for receiving the inner wall portion of the cup, and the chamber side of the cap includes peripheral and central flanges, or energy directors, to which a second ply of permeable lining material is ultrasonically bonded. The inner wall portion includes a beveled inner end surface which tapers radially inwardly in a direction toward the transverse web portion to facilitate insertion of a canister pipe into the inner wall portion. The inner wall portion cooperates with the canister pipe to define a return passage for the dehydrated air or fluid that passes over the desiccant in the chamber. |
