         2 . The container of  claim 1 , wherein a ratio of the second radius of curvature to the first radius curvature is between about 0.6 and about 1.0. 
     
     
         3 . The container of  claim 1 , further comprising at least one gradient upper region interposed axially between the brim and each valley. 
     
     
         4 . The container of  claim 3 , wherein each gradient upper region has a gradient thickness that decreases from the brim to an upper region edge coupled to a top end of each valley. 
     
     
         5 . The container of  claim 1 , wherein the upper region edge of each gradient upper region is arcuate. 
     
     
         6 . A container, comprising:
 a floor, a sidewall coupled to the floor and arranged to extend about a central axis, the sidewall having an exterior surface facing away from the central axis and an inner surface facing toward the central axis, the exterior surface and interior surface each having a constant sidewall radius of curvature with a center at the central axis, and   a plurality of scalloped segments coupled to the inner surface of the sidewall and facing toward the central axis, the plurality of scalloped segments including a plurality of vertically-extending ridges and a plurality of vertically-extending valleys,   wherein the plurality of vertically-extending ridges are located on a reference circle having a first radius of curvature about the central axis and each vertically-extending valley included in the plurality of vertically-extending valleys has a second radius of curvature between adjacent ridges included in the plurality of ridges, the second radius of curvature being less than the first radius of curvature.   
     
     
         7 . The container of  claim 6 , wherein a center of the second radius of curvature of each vertically-extending valley is located radially between the central axis and the sidewall. 
     
     
         8 . The container of  claim 7 , wherein each vertically-extending ridge of the plurality of vertically-extending ridges has a ridge thickness, and wherein each vertically-extending valley of the plurality of vertically-extending valleys has a valley thickness that is less than the ridge thickness. 
     
     
         9 . The container of  claim 6 , wherein each valley includes a first ramp coupled to a first ridge included in the plurality of vertically-extending ridges and a second ramp coupled to the first ramp and to a second ridge adjacent to the first ridge. 
     
     
         10 . The container of  claim 6 , wherein each of the vertically-extending ridges has a first height and each of the vertically-extending valleys has a second height less than the first height. 
     
     
         11 . The container of  claim 10 , wherein each of the plurality of scalloped segments further includes a gradient upper region coupled to an upper end of two vertically-extending ridges included in the plurality of vertically-extending ridges and to a single vertically-extending valley included in the plurality of vertically-extending valleys. 
     
     
         12 . The container of  claim 11 , wherein each gradient upper region has an upper region edge having an arcuate shape, and wherein each gradient upper region has a gradient thickness that varies as each gradient upper region extends from the upper region edge toward the brim. 
     
     
         13 . The container of  claim 12 , wherein each scalloped segment further includes an upper band coupled to a top end of each gradient upper region and to the brim, the upper band having a substantially constant band thickness greater than or equal to the gradient thickness. 
     
     
         14 . A container, comprising:
 a floor,   a sidewall coupled to the floor and arranged to extend about a central axis, and   a plurality of ridges coupled to an inner surface of the sidewall,   wherein each of the ridges included in the plurality of ridges is spaced a first distance from the central axis and the sidewall is spaced a second distance from central axis, the first distance being less than the second distance.   
     
     
         15 . The container of  claim 14 , further comprising a plurality of valleys, each valley included in the plurality of valleys being located between two adjacent ridges included in the plurality of ridges. 
     
     
         16 . The container of  claim 15 , wherein each ridge of the plurality of ridges has a ridge thickness, and wherein each valley of the plurality of valleys has a valley thickness that is less than the ridge thickness.
