Cap for storing materials separate from a body of liquid and facilitating subsequent mixing of the materials and the liquid
First Claim
1. A closure adapted to attach over an opening of a container, the container closure comprising:
- a body comprising an outer collar configured to be secured to a finish of the container, and an annular wall extending away from the outer collar, wherein at least a portion of the annular wall surrounds a storage compartment;
a nozzle received on the annular wall, wherein the nozzle comprises an opening;
a cap receivable over a portion of the annular wall and the nozzle, the cap having first and second opposing ends;
an annular pull strip surrounding the annular wall and spacing the first end of the cover from the outer collar; and
a plunger disposed within the storage compartment, wherein the pull strip prevents movement of the plunger towards the outer collar when the pull strip is spaced between the cap and the outer collar around the annular wall, and wherein at least partial separation of the pull strip from the annular wall allows movement of the plunger towards the outer collar.

Abstract
A closure attachable over the opening of a container that selectively facilitates mixing of a component (e.g., supplement, vitamins, etc.) of any appropriate form (e.g., powders, flakes, liquids) with a liquid in the container to create a mixture. In one aspect, the closure includes a body, a storage compartment within the body, a nozzle movably received on the annular wall, a cap receivable over a portion of the body and the nozzle, an annular pull strip surrounding the body and spacing the first end of the cap from an outer collar of the body, and a plunger disposed within the storage compartment that is adapted to selectively break a seal to allow for mixing between the component and the liquid.

13. A closure adapted to attach over an opening of a container, the container closure comprising:
-
a body comprising an outer collar and an annular wall extending away from the outer collar, wherein the outer collar is configured to be secured to a finish of the container, and wherein at least a portion of the annular wall surrounds a storage compartment; a hollow stem disposed within the storage compartment, the hollow stem comprising an interior cavity; a nozzle received over an outer surface of the annular wall and comprising an aperture, wherein the nozzle is movable between at least a) a closed position in which the hollow stem is received in the nozzle aperture to limit the exit of fluids from the storage compartment via the nozzle aperture and b) an open position in which the hollow stem is spaced from the nozzle aperture to allow the exit of fluids from the storage compartment via the nozzle aperture; and a plunger disposed within the storage compartment and the interior cavity of the hollow stem, wherein the nozzle is movable relative to the plunger between the closed and open positions. - View Dependent Claims (14, 15)

16. An apparatus comprising:
-
a liquid container adapted to store a liquid and comprising a container opening; and a closure adapted to attach to the liquid container around the container opening, the container closure comprising; a body comprising an outer collar and an annular wall extending away from the outer collar, wherein the annular wall surrounds a storage compartment; a nozzle received on the annular wall, wherein the nozzle comprises an opening; a cap received over the nozzle; an annular pull strip surrounding the annular wall and spacing the cap from the outer collar; a seal adapted to prevent mixing between a component contained in the storage compartment and liquid in the liquid container when the container closure is attached to the liquid container; and a plunger disposed inside of the storage compartment, wherein the plunger is prevented from breaking the seal when the pull tab is spaced between the cap and the outer collar around the annular wall, and wherein the plunger is allowed to break the seal when the pull tab is at least partially separated from the annular wall to thereby allow for mixing between the component and the liquid in the liquid container to create a mixture. - View Dependent Claims (17)
