Abstract:
1. A device for producing a vapor having disinfecting properties when exposed to ambient moisture, comprising: at least two outer membranes permeable to moisture and vapor; and at least one inner membrane continuously sealed to the at least two outer membranes along at least one side of the device, and non-continuously sealed along at least one side of the device; wherein the outer membranes and the inner membrane together form a first compartment and a second compartment separated by the inner membrane, wherein the first compartment is provided with a first dry reactant and the second compartment is provided with a second dry reactant, and wherein the first dry reactant and the second dry reactant are different, and whereby the vapor having disinfecting properties is generated and released to the atmosphere from the device when the first dry reactant in the first compartment is hydrated by moisture penetrating the outer membranes, and the hydrated first dry reactant is transported across the inner membrane to contact the second dry reactant in the second compartment to generate the vapor having disinfecting properties, and wherein the first dry reactant and the second dry reactant chemically react with each other when hydrated to generate the vapor.
