Abstract
An insulated container with a double wall construction having a removable partition centrally located within the container dividing the container into two compartments. A top is pivotally mounted on the partition and is constructed to close one of the compartments at a time. Liquid in one compartment flows to the other compartment through a connection provided at the bottom of the partition. The container, the partition and the top are all thermally insulated.
Claims23
A multiple compartment thermally insulated beverage container having opposed wall surfaces with insulating means therebetween, said container including longitudinally extending partition means inside said container defining multiple compartments separate one from the other along substantially the entire portion thereof, said partition means comprising two opposing imperforate wall surfaces with insulating means therebetween, said imperforate wall surfaces being spaced from and interconnected to each other about the periphery thereof, stop means for causing the bottom periphery of said imperforate wall surfaces to be spaced above the bottom of the container thereby providing communication between compartments and top means enclosing at least one of said compartments while allowing another compartment to remain substantially opened at the top thereof, said top means comprising a closure pivotally connected to the upper part of said partition means between the opposing imperforate wall surfaces.
A two compartment thermally insulated beverage container comprising an outer cylindrical casing having a closed bottom and a circular edge defining an open top, an inner cylindrical casing having a closed bottom and an upwardly and outwardly extending lip with an exterior downwardly extending flange defining a circular edge connected to said circular edge of said outer casing and defining a closed space between said inner and outer casings, a handle extending outwardly from said outer casing, a first and second pair of longitudinally extending spaced apart guides on the inner surface of said inner casing extending between the bottom of said inner casing and terminating below said lip, said first and second pair of guides being diametrically positioned and aligned with said handle, a ledge on the interior surface of said inner casing extending therearound and extending upwardly along said interior surface from the juncture thereof with said first and second pair of guides with the uppermost portions of said ledge being diametrically positioned 90.degree. from said guides, a partition having spaced apart flat walls defining a closed space therebetween constructed to slide between said first and second pair of guides and to be frictionally engaged thereby, said partition having a bottom terminating above the bottom of said inner casing and having a plurality of legs extending downwardly therefrom for engagement with said inner casing bottom and defining passageways interconnecting the two compartments formed on opposite sides of said partition, and a semi-elliptical double walled top having a resilient gasket therearound journaled for rotation in said partition wherein the arcuate portion of said top rests on said ledge and said gasket forms an air tight seal between said top and said inner casing above said ledge, said top slanting downwardly from the uppermost portion of said ledge toward said partition.
