Chemical delivery assembly

A chemical delivery system, comprising:

• 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 exterior housing element including a top portion and containing said heating element;
• and
• a lid including a first horizontal wall, a first plurality of vertical walls coupled to one another and depending downwardly from said first horizontal wall, and a well spaced radially inwardly relative to said first plurality of vertical walls and depending downwardly from said first horizontal wall, said chemical storage device being mounted to said well, said heating element being in thermal communication with said chemical storage device via said well, said first plurality of vertical walls being attached to only said top portion of said housing element.

A method of using a chemical delivery system, said method comprising the steps of:

• providing a heating element which provides an exothermic chemical reaction, a chemical storage device, and an at least substantially rigid housing element containing said heating element;
• attaching a tray to said housing element, said tray including a well, said well having an absence of a through-hole and defining a space which is slightly larger than said chemical storage device;
• mounting said chemical storage device to said well;
• attaching a retainer to said well, said retainer including at least one hole;
• retaining, using said retainer, said chemical storage device in said space;
• removing a removable covering from said tray, prior to said step of removing said removable covering being directly attached to said tray and covering said retainer and said well to thereby hermetically seal said chemical storage device within said space;
• heating said heating element;
• thermally communicating said heating element with said chemical storage device via said well;
• emitting a volatilized chemical from said chemical storage device;
• and
• passing said volatilized chemical to an ambient environment through said at least one hole.
