A closure element for a beverage container is in the form of a sports cap, other closer, or initially closed straw, and provides a chamber for containing colorants in the form of liquids, gels, granules, powders, tablets or other solid bodies. Closures such as valves, rupturable membranes, hinged doors, clamps or undersized holes provide closer structure for initially keeping the chambers closed with respect to the colorant so that colorant does not flow into the beverage until released to do so by the customer. Upon opening ends of the chambers, colorants flow into beverages in the containers, which containers are made of see-through/clear or partially see-through materials. In a preferred embodiment, the colorant is a material enclosed in at least one capsule which flows through openings in the chamber within the closure element when the capsule is ruptured or perforated. Coloration of the beverage is voluntarily initiated by the consumer, and the thus colored beverages are then consumed by passage through the closure element. In one embodiment of the invention, the colorant is a medicinal agent which can be colored or may be clear. The medicinal agent is released into liquid, which may be water, for ingestion by a patient.
