Abstract
A closure for use with a beverage container, the closure having a plurality of compartments formed therein to store quantities of a flavoring agent separately from a mixing fluid (such as water) contained in the container. The compartments are operable by simple finger pressure to release their contents into the container one at a time for the purpose of making a flavored beverage. Support ribs are formed on the closure to allow the stacking of a number of closures or closure/container combinations without inadvertently releasing the flavoring agent from the compartments.
Claims6
A molded plastic closure for a mixing container comprising:
- a base having a vertical axis of substantial symmetry when in a normal storage disposition;
- inner and outer spaced, substantially-parallel, circumferentially-continuous wall portions, said inner and outer wall portions being joined at the uppermost extremities thereof to define an inverted U-shaped channel to receive the rim of said container therein;
- the plane of said base being offset along said axis a predetermined distance below the upper extremities of said wall portions;
- at least one downwardly opening ingredient compartment formed contiguous with said base and extending upwardly therefrom to an upper wall;
- rupturable sealing means closing the bottom of said compartment;
- and
- a plurality of circumferentially spaced, substantially rigid ribs formed on said base and contiguous to the inner wall portion of said U-shaped channel and extending inwardly toward the center of said closure;
- said ribs extending axially at least as high as the upper wall of said compartment such that a container may be stacked thereon without collapsing said ingredient compartment along said axis.
