  • Patent number: 6767521
    Abstract: A system for dehumidifying and deodorizing, the system comprising a hanging, dehumidifying and deodorizing pouch comprising a housing having a impermeable membrane and a semi-permeable securely attached to the impermeable membrane. The housing enclosing moisture-absorbent material and deodorizing material. The housing is enclosed within a jacket comprising a perforated contiguous wall; the wall defines an opening for receiving the housing. The jacket further comprises a closing member for closing the opening when the housing is within the jacket. The jacket can comprise a rigid, rectangular cage having a detachable lid. The semi-permeable membrane of the housing can comprise polyethylene or expanded polytetrafluoroethylene, individually or a combination thereof. The impermeable can comprise either polyethylene film or polypropylene film. The moisture-absorbent material can comprise a hygroscopic, deliquescent or a combination of a hygroscopic deliquescent and a gel forming polymer.
