1. A dual-chamber drink container comprising:
a container having a threaded neck and a circular upper container perimeter; a vertical partition irremovably coupled to the container, wherein said partition separates the container into two or more compartments and has a linear upper partition edge, wherein the partition creates a liquid-tight barrier between each compartment, and wherein the upper partition edge spans and is coplanar with said upper container perimeter; a lid member removably coupled to the container neck and vertical partition, wherein the lid member comprises an upper surface, two or more access openings in the upper surface, and a downwardly-facing socket; the socket closely interfitted with the upper container perimeter and upper partition edge, wherein the socket includes a center section which engages the upper partition edge; a threaded, open, locking ring removably coupled to the container and lid member, wherein the threaded ring member applies downward clamping force about the lid member when the threaded ring member is fitted over the lid member and screwed onto the threaded neck, the lid member upper surface being exposed when said locking ring is coupled to the container; a gasket member removably coupled to the upper container perimeter, upper partition edge, and lid member socket; the gasket member being shaped as a centrally-bisected circle, to closely interfit with the socket and center section on an upper side and with upper container perimeter and upper partition edge on a lower side, such that the assembly of the socket, gasket member, perimeter and partition edge enables a liquid-tight seal between the lid member and container; and wherein the upper surface of the lid member incorporates an upwardly-facing partition indicator which is parallel to, and directly above the upper partition edge. |
