ABSTRACT:
Dosing a flowable product is effected with an apparatus which has a rigid casing having a hollowed interior through which an elastic hose, which is connected to the casing, extends between casing inlet and outlet openings, and elastic rings are positioned to encircle the hose at positions adjacent each of the casing inlet and outlet openings, so that upon generation of sub- and then super-atmospheric pressure within the space between the hose and casing, the hose expands and contracts and the rings open and close the hose for product flow introduction into and ejection from the hose for dosing the product.
