Abstract
A desiccant containing cartridge ( ) has a cap ( ) and a generally cylindrically cross-sectioned cup ( ) for holding desiccant particles ( ) and a dye wafer ( ). The cup ( ) includes spaced inner and outer wall portions ( ) connected by a transverse portion ( ) to define a chamber ( ) having an opening ( ) for the placement of a dye wafer ( ) and desiccant particles ( ). The cap ( ) has a planar portion ( ) having outer circumference ( ) and inner circumference ( ) defining aperture ( ) for receiving inner wall portion ( ) of the cup ( ) and being designed for receipt in chamber ( ) to cover opening ( ). Cap ( ) further includes a peripheral flanged portion ( ) extending transversely from planar portion ( ), and having tabs ( ) with an edge portion ( ) which permit cap ( ) to cooperate with outer wall portion ( ) so that cap ( ) can be retained within chamber ( ) in one of a number of axially spaced positions to prevent shifting of dye wafer ( ) and desiccant ( ), thereby leaving a substantial portion of desiccant ( ) uncontaminated and useful for LOI testing.
