Abstract
A system, which induces air flow past a gel type product and into the environment, comprises a cartridge that includes a porous container for holding the product and a battery mounted with the container. The cartridge is formed to be received in an air flow inducing device that includes a housing having an air admitting opening and an air discharging opening. A fan is mounted in the housing to induct air flow through the air admitting opening, through the container, past the product and out of the air discharging opening into the environment. The fan is driven by a motor that is connected to two contacts mounted in the housing and positioned to make contact with the terminals of the battery when the cartridge is received in the air flow inducing device.
