DISPENSING CAP FOR BEVERAGE CONTAINER
First Claim
1. A dispensing cap sealingly mountable to a beverage container, said dispensing cap comprising:
- (a) an open-bottomed flow tube;
(b) a skirt surrounding the flow tube so as to form an annular chamber between the flow tube and the skirt, said skirt being adapted for disposition within the throat of the beverage container;
(c) a resilient annular diaphragm sealingly connecting an upper perimeter region of the skirt and an intermediate perimeter region of the flow tube; and
(d) a membrane sealingly attached to the periphery of the skirt at the lower end thereof;
wherein;
(e) a storage chamber is defined by the skirt, diaphragm, and membrane;
(f) the flow tube extends into the storage chamber, with the lower end of the flow tube being disposed above the membrane; and
(g) the lower end of the flow tube is adapted to pierce the membrane upon being pressed downward against the membrane;
such that when the dispensing cap is mounted to the beverage container with the skirt disposed within the throat thereof and with a quantity of additive substance stored in the storage chamber, a downward force applied to the flow tube will resiliently deform the diaphragm, allowing the lower end of the flow tube to push against and pierce the membrane, thus allowing the contents of the storage chamber to flow into the container.

Abstract
A dispensing cap has an open-bottomed flow tube connected to a surrounding skirt by a resilient diaphragm, and extending into a storage chamber defined by the diaphragm, skirt, and a membrane sealingly closing off the bottom of the skirt. The lower end of the flow tube is disposed above and closely adjacent to the membrane, and is adapted to pierce the membrane when pressed downward against it. The dispensing cap is sealingly mountable to a beverage container with the skirt and storage chamber disposed within the throat of the container. A downward force applied to the flow tube will resiliently deform the diaphragm and force the lower end of the flow tube against and pierce the membrane, thus releasing the contents of the storage chamber into the container, which can then be agitated to mix the storage chamber contents with liquid in the container.
