         9 . The bottle of  claim 4 , wherein the first groove is positioned closer to the bell than the second groove, and wherein the first and second grooves are configured, in response to a load applied to the bottle, to direct the load from each of the first valleys of the plurality of first valleys of the first groove towards each of the closest second peaks of the plurality of second peaks of the second groove. 
     
     
         10 . A bottle comprising:
 a finish defining a bottle opening;   a neck coupled to the finish;   a bell coupled to the neck;   a base;   a sidewall extending between the bell and the base;   a central axis extending from the finish to the base;   a first groove extending around the sidewall, the first groove having a wave shape defined by at least one peak and at least one valley; and   a second groove extending around the sidewall, the second groove having a wave shape defined by at least one peak and at least one valley, the second groove being circumferentially offset from the first groove, and spaced from the first groove along the central axis.   
     
     
         11 . The bottle of  claim 10 , wherein the first groove and the second groove are sinusoidal in shape. 
     
     
         12 . The bottle of  claim 10 , wherein the second groove is circumferentially offset from the first groove by an angular distance of 5 degrees to 45 degrees. 
     
     
         13 . The bottle of  claim 10 , wherein the at least one peak of the second groove is circumferentially offset from the at least one peak of the first groove by an angular distance of 5 degrees to 45 degrees. 
     
     
         14 . The bottle of  claim 10 , wherein the at least one valley of the second groove is circumferentially offset from the at least one valley of the first groove by an angular distance of 5 degrees to 45 degrees. 
     
     
         15 . The bottle of  claim 10 , wherein the first groove is positioned closer to the bell than the second groove, and wherein the first and second grooves are configured, in response to a load applied to the bottle, to direct the load from the at least one valley of the first groove towards the closest at least one peak of the second groove. 
     
     
         16 . A bottle comprising:
 a neck defining a bottle opening;   a bell coupled to the neck;   a base;   a sidewall extending between the bell and the base;   a central axis extending from the neck to the base;   a first groove extending around an outer circumference of the sidewall, the first groove having a wave shape defined by alternating first peaks and first valleys; and   a second groove extending around an outer circumference of the sidewall, the second groove having a wave shape defined by alternating second peaks and second valleys, the second groove being circumferentially offset from the first groove such that the alternating second peaks and second valleys of the second groove are positioned out of vertical alignment with the alternating first peaks and first valleys of the first groove.
