Abstract
A container closure is disclosed for retaining an additive material to mix with a container material within a container. The container closure comprises a reservoir having a sleeve and a plunger for retaining the additive material. A resilient seal is located at a first end of the sleeve and a frangible wall is located at a second end of the sleeve. The plunger is slidably received within the sleeve with the resilient seal interacting between the sleeve and the plunger. A severable member coacts between the base and the plunger for spacing a plunger projection from the frangible wall. The severable member is removable for enabling the plunger to be moved into a depressed position to fracture the frangible wall to permit the additive material to enter the container.
