an end wall including an outer peripheral edge, an upper surface, a lower surface and a first thickness measured between the upper and lower surfaces; a sidewall extending downward and away from the outer peripheral edge of the end wall, the sidewall including an inner surface, an outer surface and a second thickness measured between the inner and outer surfaces; a container engagement structure extending radially inward from the inner surface of the sidewall; a tamper-indicating band extending from a lower end of the sidewall, the tamper-indicating band having a frangible section configured to break upon opening to provide a visual indication that the closure had been opened; and a plurality of raised ribs extending radially outward from the outer surface of the sidewall and extending along the sidewall at least a portion of the distance between the outer peripheral edge and the tamper-indicating band; a circumferentially continuous annular wall extending downward from the lower surface of the end wall; the end wall including an inner section having an outer peripheral edge adjacent an inner surface of the annular wall and a center portion, the outer peripheral edge of the inner section and the center portion each having a third thickness; at least a portion of the inner section located between the center portion and the outer peripheral edge of the inner section having a thickness equal to the first thickness; wherein the first thickness is less than the third thickness; and wherein the first thickness is less than 75% of the second thickness. |
