Abstract

A bottle cap is adapted to retain a quantity of an additive, such as for example aspirin or the like. The additive is retained in an isolated condition within a sealed chamber or within a bladder inside the bottle cap but in fluid communication with the liquid within the bottle, such as water. A cap with at least one downward extending protrusion is provided to breech the seal of the chamber or the bladder, thereby releasing some or all of the additive retained within the bottle cap.

Claims

1. A beverage dispenser comprising:

a. a bottle having a threaded neck, wherein the bottle is adapted to retain a quantity of a liquid; and

b. a bottle cap assembly comprising

i. a rotatable outer cap forming a chamber for retaining a quantity of additive, the rotatable outer cap comprising an inner concentric barrel with at least one downwardly extending tooth and the rotatable outer cap also having at least one inwardly extending protrusion;

ii. an inner cap for threadably engaging the threaded neck of the bottle and the inner cap having a J-slot for engaging the at least one inwardly extending protrusion within the outer cap, wherein a molded lip formed on the inner cap presses the inner concentric barrel of the outer cap sealing the upper end of the chamber;

iii. a penetrable membrane between the chamber and the quantity of a liquid, wherein the penetrable membrane is in fluid communication with the quantity of a liquid;

iv. a seal ring in contact with a top of the threaded neck of the bottle and the penetrable membrane, the seal ring providing an interference fit within the bottle neck, wherein the penetrable membrane forms a seal across the seal ring thereby forming a lower seal for the chamber across the area of the threaded neck of the bottle;

v. the J-slot formed in an outside surface of the inner cap, wherein the at least one inwardly extending protrusion formed in the outer cap extends into the J-slot and is adapted to define relative movement between the inner and outer caps; and

vi. wherein the J-slot has at least one knuckle for retaining the at least one inwardly extending protrusion;

wherein the rotatable outer cap rotates around the inner cap enabling the at least one inwardly extending protrusion of the outer cap to move toward the end of the J-slot enabling the at least one tooth to pierce the penetrable membrane allowing the additive to mix with the quantity of fluid and the rotatable inner cap rotates the at least one inwardly extending protrusion of the outer cap toward the opposite end of the J-slot enabling twisting of the inner cap off the threaded neck of the bottle.

2. The dispenser of claim 1, further comprising at least two teeth extending down from the underside of the outer cap and adapted to penetrate the membrane upon relative movement between the inner and outer caps.

3. The dispenser of claim 2, wherein clockwise movement between the inner and outer caps causes the at least one tooth to penetrate the membrane.

4. The dispenser of claim 1, further comprising a tamper indicator formed in the bottle cap.
