Abstract (en)
[origin: WO2011129701A1] A filter (1) has a conical outer wall (3) of which the end having the smaller diameter forms a mouthpiece (5) and the other end a suction piece (7). Within the outer wall there is an inner wall 9 which also has a conical shape and whose end 11 having the larger diameter is connected to the mouthpiece (5) while the other end (13) is present near the suction piece (7). The conical shape of the inner wall provides that the current of air is optimised. The suction piece (7) comprises a cover grid (15) of which the middle section is closed and is present distal from the end (13) of the inner wall. Between the inner wall (9) and the outer wall (3) there is a receiving reservoir (19) where the redundant particles of tobacco/weed/dust (21) end up in. Between this end (13) and the middle section (17) of the cover grid there is an opening (23) which is connected in straight lines (15) to the suction openings (27) in the suction piece (7).
