Abstract
A drawn and ironed container having a reduced neck around an upper open end has a bottom profile which exhibits excellent strength characteristics and nests with an end double-seamed to the open end of the container. The bottom profile includes a center spherical dome surrounded by a U-shaped annular portion defining a lower support surface for the container. A joining segment is integral with the container side wall and the U-shaped annular portion includes a first annular arcuate portion having an exterior radius and a second annular arcuate portion having an interior radius.
Claims6
A drawn and ironed beer and beverage container including a generally cylindrical side wall having an inwardly-tapered reduced neck at one end with a reduced diameter end connected by a double seam to an open end of said reduced diameter neck, said double seam having an inner generally flat wall that extends generally parallel to the axis of said container with an upper arcuate exposed portion above said inner flat wall;
- an integral bottom including a first lower convex annular arcuate portion at the end of said cylindrical side wall, a concave annular second arcuate portion integral with a lower end of said first lower convex annular arcuate portion and a generally U-shaped annular third portion, said second arcuate portion adapted to engage said arcuate exposed portion of double seam when stacking a lower portion of a container upon an upper portion of another container, said U-shaped annular third portion having an outer annular flat wall tapered inwardly and an inner substantially vertical flat wall interconnected by a lower arcuate segment that defines a reduced diameter lower annular support for said container;
- and an inwardly-domed central panel integral with said substantially vertical flat wall.
A thin walled drawn and ironed metal beverage container capable of being stacked onto a similar beverage container comprising a generally cylindrical side wall having an inwardly-tapered neck at one open end and an integral bottom wall at an opposite end with an end connected by a double-seam to said open end;
- said double-seam having an upper arcuate portion and defining an inner diameter which is less than the diameter of said side wall and having a substantially vertical inner wall, said bottom wall having a central inwardly-domed panel with a U-shaped annular segment integral with an outer peripheral edge of said central panel portion, said U-shaped annular segment having a substantially vertical flat inner wall and an upwardly- and outwardly-inclined outer wall interconnected by lower arcuate segment defining an exposed support surface having a diameter less than said side wall and said double-seam inner diameter;
- and a joining segment having a first arcuate segment defining an exposed convex annular arcuate portion integral with said side wall and a second annular arcuate portion defining an exposed concave surface integral with said outer wall of said U-shaped segment so that, upon stacking of a lower portion of a container onto an upper portion of another container, said concave surface will provide continuous extended contact with said upper arcuate portion of said double-seam and said U-shaped annular segment will be partially wedged into said double-seam to prevent tiling of the upper container with respect to the lower container.
