Bottle with a light weighted base

Abstract

The present application provides a bottle. The bottle may include a sidewall and a base section. The base section includes a number of ribs extending from a center dome to a flex surface about the sidewall to resist deformation in the sidewall.

We claim: 
     
         1 . A bottle, comprising:
 a sidewall; and   a base section;   the base section comprises a plurality of ribs extending from a center dome to a flex surface about the sidewall to resist deformation in the sidewall.   
     
     
         2 . The bottle of  claim 1 , wherein the center dome extends within the sidewall. 
     
     
         3 . The bottle of  claim 1 , wherein the base section comprises a support ring positioned between the center dome and the flex surface. 
     
     
         4 . The bottle of  claim 3 , wherein the center dome, the support ring, and the flex surface comprise a substantially flat “U” shape in cross-section. 
     
     
         5 . The bottle of  claim 1 , wherein the plurality of ribs comprises plurality of fully extending ribs and a plurality of partially extending ribs. 
     
     
         6 . The bottle of  claim 5 , wherein the central dome comprises a boss and wherein the plurality of fully extending ribs extends from adjacent to the boss, through the support ring, and through the flex surface. 
     
     
         7 . The bottle of  claim 5 , wherein the central dome comprises a mid-section and wherein the plurality of partially extending ribs extends from the mid-section, through the support ring, and through the flex surface. 
     
     
         8 . The bottle of  claim 5 , wherein each of the plurality of the fully extending ribs is positioned adjacent to a pair of the plurality of partially extending ribs. 
     
     
         9 . The bottle of  claim 5 , further comprising about a twenty ounce volume, wherein the plurality of fully extending ribs comprises five fully extending ribs, and wherein the plurality of partially extending ribs comprises five partially extending ribs. 
     
     
         10 . The bottle of  claim 1 , wherein the sidewall comprises a cylindrical shape. 
     
     
         11 . The bottle of  claim 1 , further comprising a polyethylene terephthalate material. 
     
     
         12 . The bottle of  claim 1 , further comprising about 20.5 grams of a polyethylene terephthalate material. 
     
     
         13 . The bottle of  claim 1 , wherein the plurality of ribs flex in response to a negative internal bottle pressure to resist deformation in the sidewall. 
     
     
         14 . The bottle of  claim 1 , further comprising a volume of water therein. 
     
     
         15 . A polyethylene terephthalate bottle, comprising:
 a sidewall; and   a flexible base structure;   the flexible base structure comprises a plurality of ribs extending from a center dome, through a support ring, and into a flex surface about the sidewall to resist deformation in the sidewall.   
     
     
         16 . The polyethylene terephthalate bottle of  claim 15 , wherein the center dome, the support ring, and the flex surface comprise a substantially flat “U” shape in cross-section. 
     
     
         17 . The polyethylene terephthalate bottle of  claim 15 , wherein the plurality of ribs comprises plurality of fully extending ribs and a plurality of partially extending ribs. 
     
     
         18 . The polyethylene terephthalate bottle of  claim 17 , wherein the central dome comprises a boss and wherein the plurality of fully extending ribs extends from adjacent to the boss, through the support ring, and through the flex surface. 
     
     
         19 . The polyethylene terephthalate bottle of  claim 17 , wherein the central dome comprises a mid-section and wherein the plurality of partially extending ribs extends from the mid-section, through the support ring, and through the flex surface. 
     
     
         20 . The polyethylene terephthalate bottle of  claim 15 , wherein the plurality of ribs flex in response to a negative internal bottle pressure to resist deformation in the sidewall.
