Abstract
Flavoring, dietary minerals, vitamins, other nutritional supplements, or medicines may be dispensed in a filter assembly designed to cap a neck or open end of a bottle. A cap has a manual valve extending from the top thereof and operatively connected to the bottom thereof is an activated carbon block tubular filter having a porosity of between about 8-120 microns. Disposed within the tubular carbon block is a soluble solid porous element, having a porosity greater than that of the carbon block, and having a solubility between about one quarter and one-one hundredth of sucrose. The soluble element is at least in part a flavoring, vitamin, dietary mineral, nutritional supplement, or medicine. It also may be tubular, and substantially lining the soluble porous element may be a hydrophobic membrane which allows passage of water therethrough under pressure, but not under static pressure conditions.
