Abstract An outer container to maintain a liquid disposed in an inner container in a highly chilled condition for a prolonged period comprising a pair of cup-like shell combinations, each including an outer shell lined with styrafoam and an inner cup-like shell suspended from the rim of the outer shell to be inserted within the thus-lined outer shell, but spaced from lined walls. Such spacing is filled with semi-solid plastic jell, such as ''''blue ice''''. Each inner cup-like shell is mounted on the rim of its outer shell by an integral outwardly flaired annular portion, the edge of which interlocks with the rim area of the outer shell, thereby containing the plastic jell. The two shell combinations are then brought together with their respective cavities disposed in registry and means are provided to interlock the rims of the shell combinations. Such means may involve some type of mating threading on the two rims, the use of an interlocking adapter, or the use of an intermediate sleeve-like member having a similar wall structure to that of the two shell combinations with appropriate end means to be secured to and in registry with the rim of each shell combination. By use of the latter, the overall axial dimension of the container may be increased to accommodate larger sized liquid or filled inner containers, or otherwise to provide a larger capacity.
A container to maintain in a highly chilled condition and for a prolonged period of time, an article or fluid placed in the container, said container comprising: A. A pair of cup-like shell combinations, each said combination including: i. an outer cup-shaped shell of a predetermined configuration, said outer shell being lined with styrafoam over which is coated a plastic jell such as ''''blue ice''''; ii. an inner cup-like shell of a similar configuration but having an outer dimension sufficiently less than the inner dimension of the styrafoam lined outer shell to provide spacing between the styrafoam and the inner shell when the inner shell is coaxially disposed within the outer shell; iii. said inner shell and said outer shell being provided with means to interlock the rim area of the inner shell inside the rim area of the outer shell, thereby to suspend the remainder of the inner shell coaxially within and spaced from the styrafoam lined outer shell; and B. Means to releasably engage the upper and lower cup-like shell combinations.

The container as described in claim 1, wherein the means to releasably engage the upper and lower cup-like shell combinations comprises a cylindrical segment similarly lined with styrafoam, coated with plastic jell, and having an inside diameter coinciding with the inner diameter of the upper and lower shell portions, and rims adapted to releasably engage the rims of the upper and lower shell portions.
