ABSTRACT:
Desiccation capsule (20) for the interior (32) of an article comprising a first compartment (27) containing a desiccant (30). One wall (22) of the first compartment is perforated by a first opening (25) obturated by a semi-permeable membrane or a filter (23). The moisture on the interior of the article flows through this membrane and is absorbed by the desiccant.
One of the walls (29) of the first compartment is transparent and permits the user of the article protected by the capsule to observe any change of colour or of appearance of the desiccant following the absorption of moisture. The capsule can then be withdrawn thanks to non-permanent fastening means (36) of screw or clip type and replaced by a new capsule. It is also possible to reuse the same capsule by heating the desiccant. A stopper (41) permits transport and stocking of the capsule prior to use.
