Abstract
A liquid feeding means including a reservoir for a liquid and a wick of absorbent material within the reservoir. A portion of the wick is exposed exteriorly of the reservoir for engagement by a heated element so as to produce steam. A tube having an inside diameter of capillary size is embedded in the wick and extends from its exposed portion toward the reservoir to transmit air into the reservoir as water from the reservoir is converted to steam.
