Abstract
A chemical delivery system includes: a chemical storage device configured for emitting a volatilized chemical therefrom; a heating element which provides an exothermic chemical reaction; an at least substantially rigid housing element containing the heating element; a tray including a well, the well having an absence of a through-hole and defining a space which is slightly larger than the chemical storage device, the tray being attached to the housing element, the chemical storage device being mounted to the well, the heating element being in thermal communication with the chemical storage device via the well; a retainer attached to the well and including at least one hole configured for passing therethrough the volatilized chemical to an ambient environment, the retainer being configured for retaining the chemical storage device in the space; and a removable covering directly attached to the tray and covering the retainer and the well to thereby hermetically seal the chemical storage device within the space.
