A double walled container is provided for insulating a beverage. An outer insulating shell or container is secured to the inner container that holds the beverage. A gap exists between the outer container and inner container and the air in the gap acts as an insulating barrier. The inner container is preferably a standard aluminum container. The outer container is preferably made from aluminum or a plastic polymer. The outer container may have annular or longitudinal grooves that assist in securing the outer container to the inner container, and the grooves may also provide an enhanced gripping surface as well as a visually pleasing aesthetic design. The outer container may include a base, or the base may be eliminated in favor of a sleeve configuration for the outer container.

1. A double-walled container comprising: an inner container including a side wall, a base connected to said side wall and forming a lower portion of the container, a top forming an upper portion of the container, said base including:(i) a circumferential concave portion extending circumferentially around said base,(ii) a circumferential leg protruding from said circumferential concave portion and disposed radially inward therefrom, and;(iii) a dome-shaped panel spanning between said circumferential leg; andan outer container secured to said inner container, said outer container comprising a cylindrical side wall, a base connected to said cylindrical sidewall and forming a lower portion of the outer container, and a plurality of grooves formed on said sidewall of said outer container and spaced from one another, wherein said sidewall of said outer container is separated from said sidewall of said inner container by a substantially uniform gap at locations other than where said grooves are disposed. 2. A container, as claimed in claim 1, wherein: said grooves of said sidewall contact the sidewall of said inner container. 3. A container, as claimed in claim 1, wherein: an inner diameter of said outer container is smaller than an outer diameter of said inner container prior to attachment of the outer container to the inner container, thereby enabling a friction fit or a press fit connection between said inner and outer containers. 4. A container, as claimed in claim 1, wherein: said base of said outer container further includes a radially converging portion, a circumferential leg protruding from said radially converging portion and disposed radially inward from said radially converging portion, and a dome shaped panel spanning between the circumferential leg, wherein said radially converging portion of said outer container aligns with said circumferential concave portion of said inner container, and said dome shaped panel of said inner container has a substantially similar curvature as compared to a curvature of said dome shaped panel of said outer container, and said circumferential leg of said outer container contacts said circumferential leg of said container. 5. A container, as claimed in claim 4, wherein: said dome shaped panels of said inner and outer containers have substantially similar curvatures and the panels are placed in a nested configuration. 6. A container, as claimed in claim 1, further including: upper and lower tapered portions disposed on said sidewall of said outer container. 7. A container, as claimed in claim 1, wherein: said grooves extend longitudinally along the sidewall of the outer container, and are spaced from one another circumferentially along a circumference of said outer container. 8. A container, as claimed in claim 7, wherein: said sidewall of said outer container is substantially cylindrical, and said longitudinal grooves are substantially V-shaped in cross-section. 9. A container, as claimed in claim 7, wherein: an area of the sidewall of said outer container disposed between adjacent longitudinal grooves forms a radially extending protrusion separated from the sidewall of the inner container. 10. A container, as claimed in claim 1, wherein: said sidewall of said inner container is spaced approximately ⅛th of an inch from said sidewall of said outer container, and wherein said sidewalls maintain said ⅛th inch spacing circumferentially around said inner container except where said grooves of said outer container are located. 11. A container, as claimed in claim 1, wherein: said sidewall of said outer container includes upper and lower tapered portions that converge radially inward. 12. A container, as claimed in claim 1, wherein: said grooves extend annularly along the sidewall of the outer container, and are spaced from one another longitudinally along a circumference of said outer container. 13. A double-walled container comprising: an inner container including a side wall, a base connected to said side wall and forming a lower portion of the container, a top forming an upper portion of the container, said base including: a. a circumferential concave portion extending circumferentially around said base,b. a circumferential leg protruding from said circumferential concave portion and disposed radially inward therefrom, and;(iii) a dome-shaped panel spanning between said circumferential leg; andan outer sleeve secured to said inner container, said outer sleeve comprising a cylindrical side wall, and a plurality of grooves formed on said sidewall of said sleeve and spaced from one another along said sleeve, wherein said sidewall of said inner container is separated from said sidewall of said sleeve by a substantially uniform gap at locations other than where said longitudinal grooves are disposed. 14. A container, as claimed in claim 13, wherein: said grooves of said sidewall of said sleeve contact the sidewall of said inner container. 15. A container, as claimed in claim 13, wherein: an inner diameter of said sleeve is smaller than an outer diameter of said inner container prior to attachment of the sleeve to the inner container, thereby enabling a press fit connection between said inner container and said sleeve. 16. A container, as claimed in claim 13, further including: upper and lower tapered portions disposed on said sidewall of said sleeve. 17. A container, as claimed in claim 13, wherein: said grooves are substantially evenly spaced from one another. 18. A container, as claimed in claim 13, wherein: said grooves extend longitudinally along the sidewall of the outer container, and are spaced from one another circumferentially along a circumference of said outer container. 19. A container, as claimed in claim 18, wherein: said sidewall of said sleeve is substantially cylindrical shaped, and said longitudinal grooves are substantially V-shaped or U-shaped when viewed in cross-section. 20. A container, as claimed in claim 13, wherein: an area of the sidewall of said sleeve disposed between adjacent longitudinal grooves forms a radially extending protrusion separated from the sidewall of the inner container. 21. A container, as claimed in claim 13, wherein: said sidewall of said inner container is spaced approximately ⅛th of an inch from said sidewall of said sleeve, and wherein said sidewalls maintain said ⅛th inch spacing circumferentially around said inner container except where said grooves of said sleeve are located. 22. A container, as claimed in claim 13, wherein: said sidewall of said outer sleeve includes upper and lower tapered portions that converge radially inward. 23. A container, as claimed in claim 13, wherein: said grooves extend annularly along the sidewall of the outer container, and are spaced from one another longitudinally along a circumference of said outer container.
