US 2003/0205140 A1 · Ploypropylene or polyester plastic dessicant cartridge with fiberglass filter and bead cage ends

Abstract

A desiccant container (2) which comprises a generally cylindrically cross-sectioned cup, two dual-density fiberglass discs (6, 8), desiccant material (4), and a cap (16). The cup includes an outer annular portion, an inner tubular portion, and a bottom which connect together to define a space within. The cap (16) has a planar portion with an aperture for receiving the inner wall portion of the cup and is designed for receipt in the chamber to cover the opening. The cap further includes an outer annular rim portion extending transversely from the planar portion. The peripheral flange portion having tabs with an edge portion which permit the cap to cooperate with the outer wall portion having tabs with an edge portion which permit the cap to cooperate with the outer wall portion so that the cap can be retained within the chamber in one of a number of axially spaced positions to prevent shifting of, and escape of the desiccant.
