Device for dosing solid particulate material

A dosing device, DOSDEV (2), for dosing solid particulate material (4-1) into a receptacle;

• DOSDEV (2) comprises a dosing element (1) which consists of an inner tube shaped extension (1-1) and an outer tube shaped extension (1-2), both extensions protrude downwards at the lower side of DOSDEV (2);
• the inner tube shaped extension (1-1) and the outer tube shaped extension (1-2) are coaxially aligned with respect to each other;
• the inner tube shaped extension (1-1) is located within the outer tube shaped extension (1-2);
• the outer diameter of the inner tube shaped extension (1-1) is smaller than the inner diameter of the outer shaped extension, whereby a space, SPACE (1-3), is formed between the outer tube shaped extension (1-2) and the inner tube shaped extension (1-1), the SPACE (1-3) extending circumferentially around the inner tube shaped extension (1-1);
• the inside of the inner tube shaped extension (1-1) forms a dosing chamber (1-4);
• the opening at the lower end of the inner tube shape extension forms an opening (1-9) of the dosing chamber (1-4) at its lower end;
• the wall of the outer tube shaped extension (1-2) extends beyond the rim (1-7) of the end of the wall of the inner tube shaped extension (1-1) in axial direction and has a bend, BEND (1-5), in the axial proximity of the end of the wall of the inner tube shaped extension (1-1), by this BEND (1-5) the wall of the outer tube shaped extension (1-2) extends radially inwards at least partially around the end of the inner tube shaped extension (1-1);
• the outer tube shaped extension (1-2) ends with an opening whose diameter is smaller than the inner diameter of the outer tube shaped extension (1-2) axially before the BEND (1-5);
• the SPACE (1-3) extends over the inner surface of the BEND (1-5) and further on to the rim (1-6) of the end of the wall of the outer tube shaped extension (1-2), thereby radially inwards from the BEND (1-5) the SPACE (1-3) ends in an opening slit, SLIT (1-8), between the end of the inner tube shaped extension (1-1) and the end of the outer tube shaped extension (1-2);
• the rim (1-6) of the end of the wall of the outer tube shaped extension (1-2) does not extend in a radial inward direction beyond the inner diameter of the end of wall of the inner tube shaped extension (1-1).
