Abstract
A closure is described which incorporates an additive delivery system integral with the closure. The system includes a dosing chamber formed in the closure, the dosing chamber exhausting the contents into the container upon initial unthreading of the closure from the container. The design prevents premature dosing of the chamber into the container and also allows the dosing chamber to be pressurized if so desired.
