Definitions

  • the adjacent ends of the two beads are interconnected by an arcuate portion that produces a convex surface within the container and the portion of the container bottom wall within the inwardly directed bead is generally flat and merges with the adjacent end of the inwardly directed bead along a further arcuate portion that defines a concave surface within the container.
  • the two-piece container consists of a body that has an inte gral botom wall at one end and the opposite end is configured to have a closure secured'the'reto.
  • An early ex ample of such type'of container is disclosed in US. Pat. No. 2,142,743.
  • the profiled container bottom wall is joined to' the side wall by an outwardly directed bead so that the peripheral edge of the bottom wall is less in diameter than the outside-diameter of the container.
  • the bottom wall consists of a flat circular panel at the center of the container which has an annular spherical portion around the periphery thereof that defines a concave surface inside the container.
  • the annular spherical surface is connected'to the outwardly directed bead through an arcuate portion having compounded radii.
  • This connecting portion consists of an upwardly directed bead having one end connected to the outer end of the spherical. annular section and the opposite end connected to the adjacent end of the bead through an arcuate portion that define a convex surface within the container.
  • the particular configuration of the bottom wall and its connection to the side wall reduces the overall diameter for the bottom wall.
  • the arcuate portion defining the convex surfaces also adds stiffness or rigidity to the container bottom wall to thereby improve the buckling resistance as compared to conventional dome profiles.
  • FIG. 1 shows a fragmentary side elevation view, partly in section, showing the bottom portion of a drawn and ironed container
  • FIG. 2 is an enlarged fragmentary sectional view of the outer periphery of the container bottom wall and a small portion of the side wall.
  • the container of the present invention designated by the reference numeral 10, has a cylindrical side wall 12 and a bottom wall 14 which are joined with each other by an annular outwardly directed bead 16.
  • the container bottom wall 14 has an inverted flat dome profile at the center thereof which is connected to outwardly directed bead or punch nose portion 16 through a portion 20 which has a double curvature between bead 16 and inverted fiat dome l8.
  • the configuration of the bottom wall of the container provides improved buckling resistance to withstand the internal pressures of processing and warehousing while still allowing for considerable latitude for dome-depth control and design of containers particularly adapted larly profiled bottom wall that will allow the container a for packaging carbonated beverages.
  • the bottom wall consists of an arcuate portion 22 that merges at a juncture J1 (FIG. 2) with one end of outwardly directed bead 16, the opposite end of which is connected to side wall 12 through a connecting portion 24.
  • Arcuate portion 22 is joined at its opposite end at a juncture J2 to an inwardly directed bead 26 and the opposite end of bead 26 is integrally joined with a second arcuate portion 28 which defines an annular spherical portion around a central flat portion 30.
  • an outwardly directed annular bead has a radius R1 which has its center located inside the container while inwardly directed bead 26 has a radius R2 which has its center located outside the container.
  • arcuate portion 22 has a radius R3 which is located outside the container so that a convex surface 29 is formed inside the container.
  • the second arcuate portion 28 has a radius R4 which is located inside the container and therefore defines a concave surface 32 that integrally joins flat panel 30 with the adjacent end of inwardly directed annular bead 26.
  • Container side wall 12 has an outside diameter D1 which is tapered inwardly slightly along arcuate portion 24 and is joined to arcuate portion 22 by bead 16 having radius R1. This results in having the lowermost edge of bead l6 define a diameter D2 which is smaller than the diameter D1.
  • the uppermost edge of inwardly directed bead 26 defines a diameter D3 while the peripheral edge of flat panel 30 defines a diameter D4.
  • the effective diameter of the container bottom wall will be defined by the lowermost edge of the annular bead 16 which is less than the diameter of the container and this acts as an anchor point for bottom wall 18.
  • the overall area of the container bottom wall 18, defined by diameter D2 is less than the diameter of the container.
  • the rigidity of the container bottom wall is further increased by the convex surface 29 located adjacent the outer peripheral diameter of bottom wall 18.
  • the compound curvature of the section 20 between diameters D2 and D3 is particularly important in producing an extremely rigid bottom wall with metal of minimum thickness.
  • FIG. 2 An inspection of FIG. 2 shows that a line L1 drawn tangent to the juncture J1 between arcuate surface 22 and outwardly directed annular bead l6 defines an angle A with respect to the outer adjacent surface of the container side wall 12, which is represented by the plane P drawn through the center of radius R1.
  • a second tangent line L2 at the juncture between the arcuate portion 22 and inwardly directed annular bead 26 defines an angle B with respect to plane P. It has been determined that the proper relationship of these angles plays an extremely important role in preventing outward deformation of the connecting portion 20 between diameters D2 and D3.
  • the particular radii and diameters as well as the height H1 and H2 can be directly correlated to the outside diameter of container side wall 12 and the thickness (T1) of bottom wall 18. These dimensions have been determined to be within the following ranges:
  • the side wall 12 of the drawn and ironed cylindrical container body which may be formed of either aluminum or steel, is joined to bottom 18 at a reduced diameter portion D2 and bottom wall has a compound curvature between the lowermost edge and the uppermost edge with a partial spherical annular surface inside the uppermost edge which is ultimately connected to an inverted flat panel portion that defines the center of the bottom wall 18.
  • a metal container having a cylindrical side wall and an effectively rigid bottom wall integral therewith at the bottom end thereof, said bottom wall and side wall merging along one end of an annular outwardly directed bead, said bead having an end opposite to said one end spaced diametrically inwardly thereof, said bottom wall having an annular inwardly directed bead located within said outwardly directed bead, said inwardly directed bead having opposite ends one of which is adjacent said opposite end of said outwardly directed bead, and an arcuate portion interconnecting the two adjacent ends of the respective beads, said arcuate portion producing a convex surface within said container between said beads, said arcuate portion and said beads providing resistance to outward deformation of said bottom wall when pressure is applied inside said container, said bottom wall further including a generally flat central portion within said inwardly directed bead, said generally flat portion being spaced vertically above the lower end of said outwardly directed bead and vertically below the upper end of said inwardly directed bead, said generally flat portion merging
  • said arcuate portion defines a first angle less than 15 with respect to the adjacent side wall and a line tangent to the juncture between said inwardly directed bead and said arcuate portion defines an angle of less than 35 with respect to the adjacent side wall of the container.
  • a container as defined in claim 8 in which the vertical dimension between the lowermost edge of said container and the uppermost edge of said inwardly directed bead is in the range of 15 to 25 times the thickness of said bottom wall.
  • a metal container having a cylindrical side wall and an integral effectively rigid bottom wall, said bottom wall and side wall merging along an annular outwardly directed bead having one end joined to said side wall and an opposite end spaced diametrically inwardly thereof, said bottom wall having an annular inwardly directed bead located within said outwardly directed bead, said inwardly directed bead having opposite ends one of which is adjacent said opposite end of said outwardly directed bead, said bottom wall having an arcuate portion between adjacent ends of said beads, said portion having a first juncture with said opposite end of said outwardly directed bead and a second juncture with an adjacent end of said inwardly directed bead, a line tangent to said first juncture defining an angle of less than 15 with said side wall and a line tangent to said second juncture defining an angle greater than 20 with said side wall, said arcuate portion producing a convex surface within said container between said beads, said arcuate portion and said beads providing resistance
