Abstract
A dehumidifying pouch comprising a container having a moisture-absorption compartment and a collection compartment, the moisture-absorption compartment comprising semi-permeable material that encloses a deliquescent desiccant material and an optional deodorizing material. The collection compartment comprises walls made of a moisture impervious material. The collection compartment is connected to the moisture-absorption compartment, preferably by a broken seal, so that liquids from the moisture-absorption compartment can be transferred to the collection compartment of the pouch. The semi-permeable material can comprise polyethylene or expanded polytetrafluoroethylene, individually or a combination thereof. The moisture impervious compartment can comprise either polyethylene film or polypropylene film. Alternatively, the dehumidifying pouch is comprised of one compartment having a moisture-absorption section and a moisture collection section. The dehumidifying pouch is non-spillable under normal use conditions and is disposable.
