Patent ID: 8152017

Claim:
A closure for closing an opening of a container wherein the container is configured to contain a consumable liquid and the closure is configured to contain an additive, the closure having a first end which connects to the container and a second end through which the consumable liquid and additive are dispensed, the closure comprising: a base including a reservoir defining an additive chamber and a support column; the support column being spaced laterally from, integral with and surrounding the reservoir and additive chamber; a passageway disposed between and extending around the support column and the reservoir, the passageway having an outlet arrangement at the second end of the closure for allowing the consumable liquid in the container to flow around the reservoir and through the outlet arrangement to a consumer, and the additive chamber having a chamber opening allowing the additive to exit therefrom into the consumable liquid, the chamber opening being closed by a barrier; a plunger mounted in the additive chamber for movement with respect to the additive chamber and the support column, the plunger closing one end of the additive chamber and having a pressure surface for causing the additive to pressurize and open the barrier upon advancing the plunger toward the barrier, wherein the additive flows out of the additive chamber opening and into the consumable liquid, and wherein the consumable liquid and additive cannot flow back through and out of the additive chamber when dispensed; a spout movably mounted on the support column and positioned around the plunger and the passageway, the spout having a sealed relationship with the outlet arrangement of the passageway when in a first position and an unsealed relationship with the passageway when in a second position, wherein upon moving the spout from the first to the second position and tilting the container, the consumable liquid together with the additive flows through the outlet arrangement to the consumer without having to remove the closure from the container.
