First Claim
1. Apparatus for the carbonation of liquids, comprising a liquid storage tank having opposed top and bottom and end and side walls, said tank including means for maintaining a liquid therein at ambient pressure;
- a draw tube having a first end positioned within said tank proximate said bottom wall and a second end exterior to said tank; and
a carbonator having a liquid input port coupled to said tube second end and an output line for dispensing carbonated liquid;
said bottom wall of said tank including means for collecting liquid in designated lower portions of said tank at low liquid volumes to increase the effective height within said tank of said low liquid volumes.

Abstract
An apparatus for the carbonation of liquids, such as water, comprises a liquid storage tank coupled to a carbonizer having a carbonated liquid holding tank which presents a carbon dioxide atmosphere to liquid introduced therein. The liquid introduced into the holding tank blends with the carbon dioxide atmosphere, and is held in the tank for withdrawal upon demand. The liquid storage tank maintains a liquid therein at ambient pressure, and has a draw tube for liquid removal positioned proximate the bottom wall of the tank. The tank has a channel system in the tank bottom to allow liquid to collect therein to maximize the amount of liquid which may be withdrawn. Liquid level switches sense the level of liquid within the channel system and are coupled to the carbonizer to prevent its operation when insufficient liquid is present in the storage tank.
