Dispensing apparatus is primarily intended for dispensing product from
product containers (12) by extrusion. In controlling discharge of product
a flexible tube (25) is connected to the container outlet and the tube is
engageable with drive means (29, 31) for deforming the tube and
controlling product discharged along the tube to an outlet nozzle (26).
Usually there will be valves towards the entry (27) and exit (28) of the
flexible tube and the drive means engages the tube between the spaced
positions.
