ABSTRACT:
A flow control device for controlling the flow rate of liquid through a flexible tube which comprises a body having sides and a slot to receive the flexible tube passing through the body. The slot commences at one of the sides of the body and the length of the slot is sufficient to receive most of the tube. The slot has sides spaced apart a predetermined distance sufficient to bear against the sides of the tube when in position in the slot to deform the tube inwardly and evenly along those sides a sufficient degree to provide an even, predetermined reduced flow rate through the tube. Because the tube is constricted in a routine manner by the slot of the device, a predictable reduced flow rate can be achieved for outlet tubes of a similar construction and diameter, making it possible to achieve a predetermined, proper flow rate through that tube. This device provides surprising reliability when used on a tube in conjunction with a liquid dispensing outlet controller, for simultaneous flow of milk from a bag of whole milk and a bag of reconstituted powdered milk, to achieve proper relative flow rates through the tubes from the two bags of milk.
