Abstract

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.

Claims

1. A closure element for attachment to a dispensing opening of a beverage container, the closure element comprising:

a coupling for attaching the closure element to the dispensing opening of the beverage container;

a chamber within the closure element, the chamber initially containing a colorant agent and having a first portion and a second portion, at least the first poriton being in communication with a beverage through the dispensing opening of the beverage container for allowing the colorant agent to flow into the beverage, and at least the second portion being configured to dispense the beverage therethrough as the beverage passes through the chamber;

a first closer for closing the first portion of the closure element;

a second closer for closing the second portion of the closure element;

a first opener for opening at least the first closer to let the colorant flow therethrough into the beverage, and

the second closer being openable for dispensing the beverage mixed with the colorant therethrough to the consumer.

2. The closure element of claim 1 wherein the closure element is a screw cap having threads which provide the coupling to the dispensing opening of the beverage container.

3. A closure element for attachment to a dispensing opening of a beverage container, the closure element comprising:

a coupling for attaching the closure element to the dispensing opening of the beverage container;

a chamber within the closure element, the chamber containing a colorant agent within at least one capsule and having a first portion and a second portion, the first portion being in communication with a beverage through the dispensing opening of the beverage container, and the second portion being configured to dispense the beverage therethrough as the beverage passes through the chamber;

a first closer for closing the first portion of the closure element;

a second closer for closing the second portion of the closure element;

an opener associated with the chamber for opening the capsule to let the colorant flow therefrom into the beverage, and

the second closer being openable for dispensing the beverage mixed with the colorant therethrough to the consumer.

4. The closure element of claim 3 wherein the closure element is a screw cap having threads which provide the coupling to the dispensing opening of the beverage container.

5. The closure element of claim 3 wherein the closure element comprises a first cylindrical member on the beverage container and a second cylindrical member mounted on the first cylindrical member for movement with respect thereto, a first opening through the first cylindrical member to provide fluid communication between the chamber and the beverage within the beverage container, the chamber being disposed in one of the cylindrical members.

6. The closure element of claim 5 wherein the chamber is in the first cylindrical member.

7. The closure element of claim 5 wherein the chamber is an annular channel disposed in the first cylindrical member, the annular channel having the first openings therethrough.

8. The closure element of claim 7 wherein the annular channel is disposed around a perforated hub on the first cylindrical member, the perforated hub having second openings therethrough in communication with the beverage in the beverage container and in communication with a spout portion of the second cylindrical member, wherein colorant flows through the first openings to color the beverage, and wherein the beverage with the coloring agent therein passes through the second openings into the spout for consumption by the customer.

9. The closure element of claim 8 wherein a cap mounted on the spout closes and opens the spout.

10. The closure element of claim 9 wherein the cap is a sports cap which is slidable on a neck between a first position closing openings through the neck and a second position opening openings through the neck.

11. The closure element of claim 5 wherein the opener associated with the chamber for opening the capsule comprises edges on either the second cylindrical member or the first cylindrical member adjacent the holes therethrough for penetrating the at least one capsule to open the capsule and release the colorant to flow through the holes into the beverage.

12. The closure element of claim 3 wherein the first closer comprises at least one hole in the first portion of the closure element, which at least one hole is smaller than the at least one capsule to retain the capsule within the chamber and to thereby retain the colorant within the chamber until the capsule is opened.

13. The closure element of claim 3 wherein the second closer comprises at least one hole in the second portion of the closure element which is smaller than the at least one capsule to retain the capsule and colorant therein within the chamber on one side of the hole, the second closer being openable by an opener on the otherside of the hole to let the beverage which has been mixed with the colorant flow through the hole to the consumer.

14. The closure element of claim 3 wherein the first and second closers have holes smaller than the capsule for retaining the capsule and colorant within the chamber until the capsule is opened, the colorant flowing through the first closure into the beverage upon opening the capsule and thereafter flowing through the second closer while mixed with the beverage when the beverage container is tilted.
