Abstract
A straw assembly for imparting flavor to otherwise neutral liquids such as milk or water includes a first section of straw for immersion in the neutral liquid and a second section of straw for placing in the user's mouth. Intermediate the two sections of straw is a chamber, which may be an intermediate section of the straw, for containing flavor imparting material, with the surface area of the flavor imparting material having an area greater than the chamber within which it is enclosed. The flavor imparting material may take the form of (1) a hollow cylinder mounted within the straw and spaced from the walls thereof, and (2) a separate enlarged chamber containing the flavor material, and (3) granular material held within the body of the straw by a pair of sponges or other porous material; (4) a re-entrant flavor imparting liner having a large surface area in view of its irregular inner surface, or (5) a plurality of different flavored materials which are successively introduced into the neutral liquid through the use of time delay coatings on granular flavor imparting material.
