Container bottom

Abstract

For years, can bottoms have been formed to provide structural integrity for cans, which include many different configurations. A novel profile for a container bottom is shown herein. The bottom structure includes a multi-radial domed central panel extending from its outside edge to a downwardly projecting substantially cylindrical inner leg portion. The inner leg portion extends to a generally semi-toroidal nose portion. The outside of the nose portion extends to an upwardly and outwardly inclined outer leg portion. The outer leg portion is connected to an outwardly inclined peripheral portion. The peripheral portion is connected to the lower end of the generally cylindrical sidewall portion.

1 . A container for storing a beverage having a longitudinal central axis and a generally cylindrical sidewall with an open portion at one end and a bottom structure at an opposite second end, the bottom structure comprising:
 a central panel having a plurality of generally concentric domes centered about the central axis;   a substantially cylindrical inner leg portion connected to the outermost concentric dome, wherein the inner leg portion extends generally downward from the central panel, and wherein the inner leg portion extends generally inward relative to the central axis;   a generally semi-toroidal nose portion connected to the inner leg portion, wherein the nose portion forms at least a portion of a ring which is generally tangential to a container stand plane;   an outer leg portion extending generally upward from the nose portion and generally outward from the central axis; and   a peripheral portion having a first and a second end, wherein the first end extends generally upward from the outer leg portion and generally outward from the central axis, and wherein the second end of the peripheral portion is connected to the second end of the sidewall.   
   
   
       2 . The container of  claim 1 , wherein the concentric domes further comprise a major dome and a minor dome. 
   
   
       3 . The container of  claim 1  wherein the domed central panel stands approximately 0.42 to about 0.48 inches above the container stand plane. 
   
   
       4 . The container of  claim 1  wherein the inner leg portion extends inwardly from the central axis at an angle of less than about 3°. 
   
   
       5 . The container of  claim 1  wherein the outer leg portion extends outwardly from the central axis at an angle of approximately 25° to about 35°. 
   
   
       6 . The container of  claim 1  wherein the inclined peripheral portion extends outwardly from the central axis at an angle of approximately 27° to about 33°.
