1. An additive container, comprising:
a housing defining a hollow interior configured to retain a fluid therein, the housing having an inlet leading to the hollow interior and an outlet leading to the hollow interior, the inlet and the outlet being spaced apart from one another;
an elongate tube disposed within the housing and having a first end fluidly coupled to the inlet and a second end defining an opening, the second end being positioned at an opposite end of the housing from the first end, and the second end being configured to extend above a level of fluid in the housing to allow gas to flow through the tube and into the housing; and
a valve disposed in the outlet and movable between a closed configuration in which fluid is prevented from flowing therethrough, and an open configuration in which fluid within the hollow interior can flow therethrough, the valve being configure to move from the closed position to the open position in response to a pressure increase in the hollow interior resulting from delivery of gas into the hollow interior through the tube.
