The connection of the bowl (1) and its removable lid (4) is performed by at least three radial pins (6) located radially towards the axis of rotation of the drum (1) running through holes in the collars (2) and (5) of the drum (1) and the removable lid (4), whereas the head (7) of each radial pin (6) in the engaged position rests on the surface of the inner diameter of the collar of the removable lid (4). Pivoted by a pin (8) on the head of each radial pin (6), horizontally positioned and tangentially oriented to the axis of rotation of the drum (1), is a thrust body (9) in the form of a reverse letter U, consisting of a diaphragm (11) provided with crank (12) and two perpendicular arms (10) equipped with a pin (8) so that the difference of distance between the surface (16) of the perpendicular arm (10) lying furthest from the diaphragm (11) and axis of symmetry of the cap (8) and further the distance between the surface (17) of the nearest lying surface of the inner diameter of the collar (5) when the radial pin (6) is engaged and the axis of symmetry of the pin (8) equals 70 % to 140 % of the width of the collar (2) of the drum in the radial direction, at the point of the holes for the radial pins (6). Between the surfaces (16) and (17) of the perpendicular arm (10) there is an oval passageway. The ends of the crank (12) are inserted in the rotary recessing (3) formed on the upper section of the outer surface of the collar (2) of the drum (1).<IMAGE>
