Abstract

A desiccant cartridge for a container, which contains moisture-sensitive product, wherein said desiccant cartridge contains at least one outside-connection opening via which the desiccant cartridge is joined to the surrounding air, a desiccant being contained in a cartridge casing. A surrounding-air duct extends between the outside-connection opening and the desiccant. This surrounding-air duct forms a long diffusion path in relation to the breathing cross-sectional area of the desiccant cartridge.
