Abstract

A multi-compartment liquid storage container capable of separately storing two or more liquids which may become mixed upon pouring. The storage container comprises a primary container with an internal container of smaller diameter within the hollow of the primary container thus creating an additional storage compartment. Removal of the pull-tab provided on the primary container enables access to the contents of the primary container and the additional storage compartment. In an alternative embodiment, the primary container is provided with a non-removable lift-tab opening and a penetrable foil section is provided in the wall of the internal container. The lift-tab perforates the foil during the opening procedure to provide internal container access. Another alternative embodiment provides an internal container sub-divided by additional compartments, each sealed off from the other by a penetrable foil membrane, allowing for separate storage of a plurality of liquids simultaneously. A removable pull-tab or non-removable lift-tab opening may be provided in this arrangement, and a straw may be used to perforate the membrane between the sections, allowing access to the various liquids. In yet another alternative embodiment, the container has a plurality of access openings, each allowing access to a separate storage compartment, and when opened together, the liquids may be simultaneously poured and mixed.
