         5 . The lid for a container of  claim 1 , wherein the trough of each of the one or more inner ribs is greater than or about 0.10 mm lower than a lowest surface of the outer bead. 
     
     
         6 . The lid for a container of  claim 1 , wherein the peak of each of the one or more inner ribs is greater than or about 0.05 mm lower than a lowest surface of the outer bead. 
     
     
         7 . The lid for a container of  claim 1 , wherein a concave side of the trough of each of the one or more inner ribs is characterized by a radius of greater than or about 0.50 mm. 
     
     
         8 . The lid for a container of  claim 1 , wherein the lid body comprises a first inner rib and a second inner rib, wherein:
 the first inner rib is positioned inward of the second inner rib;   a concave side of the trough of the first inner rib is characterized by a radius of between about 0.55 mm and about 1.05 mm; and   a concave side of the trough of the second inner rib is characterized by a radius of between about 0.65 mm and about 1.05 mm.   
     
     
         9 . The lid for a container of  claim 1 , wherein an outer perimeter of the lid body defines a tear panel for removing the lid from a container. 
     
     
         10 . The lid for a container of  claim 1 , wherein a coating is disposed on a surface of the lid body. 
     
     
         11 . A container, comprising:
 a can body; and   a lid body coupled to the can body, the lid body comprising one or more inner ribs and an outer bead, wherein:
 the one or more inner ribs are concentrically aligned on the lid body radially inward from the outer bead; 
 each of the one or more inner ribs is characterized by an angle of between about 2° and about 40° relative to a plane extending through and parallel to a center panel of the lid body; and 
 each of the one or more inner ribs is characterized by a height of less than or about 0.50 mm measured from a trough of the inner rib to a peak of the inner rib. 
   
     
     
         12 . The container of  claim 11 , wherein each of the one or more inner ribs is characterized by a width of between about 1.65 and about 3.00 mm measured from the trough of each of the one or more inner ribs to the peak of the each of the one or more inner ribs along the plane. 
     
     
         13 . The container of  claim 11 , wherein the one or more inner ribs comprise a first inner rib, a second inner rib, and a third inner rib, wherein:
 the first inner rib is positioned inward of the second inner rib and the second inner rib is positioned inward of the third inner rib;   a concave side of the trough of the first inner rib is characterized by a radius of between about 0.55 mm and about 1.05 mm; and   a concave side of the trough of the second inner rib and a concave side of the trough of the third inner rib are characterized by a radius of between about 0.65 mm and about 1.05 mm.   
     
     
         14 . The container of  claim 13 , wherein a concave side of the peak of the third inner rib is characterized by a radius less than or equal to the radius of the concave side of the trough of the third inner rib. 
     
     
         15 . The container of  claim 11 , wherein two of the one or more inner ribs are separated by a distance greater than or about a width of the one or more inner ribs. 
     
     
         16 . The container of  claim 11 , wherein, wherein a coating is disposed on an interior surface of the lid body. 
     
     
         17 . A method of forming a lid for a container, comprising:
 punching a lid body into a sheet of metal material;   forming one or more inner ribs in the lid body, wherein each of the one or more inner ribs comprises a peak and a trough; and   forming an outer bead in the lid body, wherein the outer bead is disposed outward of the one or more inner ribs.   
     
     
         18 . The method of  claim 17 , wherein the lid body comprises a circular shape. 
     
     
         19 . The method of  claim 17 , wherein an outer perimeter of the lid body defines a tear panel for removing the lid from a container.
