Abstract
A storage stable fluid delivery device including a gas generator in which moisture (water) is involved in the gas generation reaction in which moisture containment is utility to prevent or retard water loss as disclosed. The moisture containment may be a moisture impermeable membrane as a permanent part of the device and may be utilized in conjunction with the gas generator when the membrane has high gas permeability for the gas being generated. The fluid delivered by such device is typically a liquid having some particular utility in its environment. The liquid dispensed may be a pharmaceutical or some other liquid having a beneficial or curative effect upon an animal or human patient or it may be a liquid such as an insecticide, fumigant, fragrance or other liquid having a relatively high vapor pressure.
