Abstract
An automatic change-over system for stock rotation of liquids packaged in plural collapsible bag-type reservoirs is described. The bag-type reservoirs are divided into primary and secondary groups, the primary group containing the supply of liquid being dispensed and the secondary group containing the liquid supply held in reserve. Automatic change-over between the primary and secondary groups of bag-type reservoirs is effected in response to a vacuum created by the empty condition in the bags in the primary group. The pressure change in the present system is the result of the deflation of the empty bag-type packages. Thus, the change-over is caused by the characteristics of the flexible bags containing the liquid being dispensed.
