The valve, through the use of an articulated linkage, serves to both open and close the flexible nozzle and further to retract the nozzle and the liquid contained therein up into the refrigerated main storage area. A basket pivotally mounted upon a track system receives the bladder and is capable of both pivoting about a horizontal axis and moving outwardly with respect to the box to permit easy removal and replacement of the liquid containing bladder.
