A container is provided which includes a top portion having an opening and a side wall extending from the top portion to an end portion of the side wall. A bottom portion is connected with the end portion of the side wall such that the top portion, the side wall and the bottom portion define an interior space of the container. At least one groove is formed in the side wall. The at least one groove includes a central arc portion and end arc portions. The central arc portion is substantially concave relative to a longitudinal axis of the container. The end arc portions are substantially convex relative to the longitudinal axis of the container. The end arc portions are formed adjacent ends of the central arc portion and communicate with an outer surface of the side wall. Desirably, the at least one groove includes a plurality of grooves. The plurality of grooves may be disposed within the rows in an interrupted configuration such that at least a portion of the outer surface is disposed between the plurality of grooves. The central arc portion and the end arc portion may be cooperatively formed to create a load stress path communicating with the outer surface of the side wall for a load applied to the container. In an alternative embodiment, the at least one groove defines a cross-sectional configuration having groove walls extending inward from the outer surface to a groove floor. The groove walls are oriented at a wall angle measured from the outer surface.

1. A container comprising:a top portion having an opening; a side wall extending from the top portion to an end portion of the side wall; a bottom portion being connected with the end portion of the side wall such that the top portion, the side wall and the bottom portion define an interior space of the container; a plurality of grooves formed in rows along the side wall and a longitudinal axis of the container, the grooves each defining a groove center such that in a cross section of the container, which is transverse relative to the longitudinal axis, the grooves overlap whereby the groove centers are angularly displaced approximately 45 degrees from groove centers of grooves in a successive row, the grooves including substantially rigid central arc and end arc portions, the central arc portion being substantially concave relative to a longitudinal axis of the container and the end arc portions being substantially convex relative to the longitudinal axis of the container, the end arc portions being formed adjacent ends of the central arc portion and communicating with an outer surface of the side wall, whereby in the cross section the end arc portions intersect with the end arc portions in successive rows to form intersection points; and the grooves forming a load path means for uniformly translating stress to the outer surface of the side wall, wherein the load path means includes the groove overlap and intersection points which form a web of longitudinal stress paths.
