The shaker consists of a plastics rod designed to be held at one end by a connector which fastens it to a support which oscillates about a vertical axis. The rod has an intermediate section (2) which extends forward of the fastening and is of reduced thickness. The rod has a first section (1) of constant thickness which adjoins the intermediate section, while the latter reduces in thickness progressively towards a third section (3). The intermediate section is between 10 and 50 cm long and its thickness reduces from about 50 mm to about 20 mm. The third section (3) of the rod is more or less straight.
