Abstract: The container 10 of the preferred embodiment comprises an outer shell 12 and an inner membrane 14 which cooperatively define a first compartment 16 and a second compartment 18. The first compartment 16 defines a first opening 20, through which the first compartment 16 receives a consumable liquid. The second compartment 18 defines a second opening 22, through which the second compartment 18 receives a second liquid. The first compartment 16 and the second compartment 18 are shaped and arranged such that greater than 50% of the surface area of the second compartment 18 is located adjacent to the first compartment 16. Alternatively, the first compartment 16 and the second compartment 18 may be shaped and arranged such that the first compartment 16 substantially surrounds at least a portion of the second compartment 18.
