Definitions

• the invention relates to a filter for a cigarette or joint, comprising an outer wall of which one end forms a mouthpiece and the other end a suction piece provided with suction openings and within which at least one inner wall is present, which inner wall has a conical shape and with a first end having the larger diameter is connected to the mouthpiece and with the other, second end having the smaller diameter is present near the suction piece, which suction piece comprises a cover grid whose middle section is closed and is present distal from the second end of the inner wall, with a receiving reservoir being present between the inner wall and the outer wall .
• the filter is introduced in that part of the cigarette or joint that is put to the mouth and is to prevent particles of tobacco or weed coming into the mouth or throat.
• the conical inner wall there is less need to suck the filter hard, so that the cigarette or joint is smoked more easily and inhalation can take place in a better and simpler way.
• the smoking of a cigarette or joint rolled with the filter is more enjoyable to the user.
• a filter of this type is known from US 2 520 307 A.
• This known filter is affixed to a cigarette or joint in lieu of rolled therein.
• a partition is present between the suction openings and the opening at the second end of the inner wall, as a result of which the suction openings are connected to the opening at the second end of the inner wall via an elongated channel.
• tar that is present in the sucked-in smoke is deposited against the side walls of the channel and particles of tobacco and weed are received in the receiving reservoir. In this way not only particles of tobacco and weed are removed from the smoke, but the tar as well, so that the taste and effect of the smoke is diminished.
• a filter that is obtained by rolling up a piece of carton.
• the cigarette paper is rolled around the mixture of tobacco and weed and the filter is affixed to the end.
• This filter provides that the complete joint can be smoked to the end without one burning one's lips. Furthermore, the filter stops tiny tobacco and weed particles coming through.
• the filter according to the invention is characterised in that the opening between the second end of the inner wall and the suction piece is connected in straight or substantially straight lines to the suction openings in the suction piece. There is no partition present between the opening in the inner wall and the suction openings, so that these openings are directly connected to each other. The result of this is that the smoke retains the tar, whereas yet small particles of tobacco and weed contained in the smoke are removed from the smoke.
• An embodiment of the filter according to the invention is characterised in that the outer wall also has a conical shape with the mouthpiece having the smaller diameter and the suction piece having the larger diameter.
• a further embodiment of the filter according to the invention is characterised in that between the second end of the inner wall and the middle section of the cover grid there is a partition which is provided with holes forming the opening mentioned above.
• Fig. 1 shows a longitudinal section of a first embodiment of the filter
• Fig. 2 shows a perspective view of the filter shown in Fig. 1 ;
• Fig. 3 shows the filter shown in Fig. 1 seen on the cover grid;
• Fig. 4 shows a longitudinal section of a second embodiment of the filter.
• Figs. 1, 2 and 3 show a first embodiment of the filter according to the invention represented in longitudinal section, in a perspective view and in side elevation, respectively.
• the filter 1 has a conical outer wall 3 of which the end having the smaller diameter forms a mouthpiece 5 and the end having the larger diameter forms a suction piece 7.
• Within the outer wall 3 there is an inner wall 9 which also has a conical shape. From this inner wall 9 a first end 11, having the larger diameter, is connected to the mouthpiece 5 while the other, second end 13, having the smaller diameter, is present near the suction piece 7.
• the conical shape of the inner wall 9 the current of air is optimised so that one needs to draw less hard on the filter.
• the suction piece 7 has a cover grid 15 of which the middle section 17 is closed and is present distal from the second end 13 of the inner wall 9. 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. There is an opening 23 between the second end 13 of the inner wall and the middle section 17 of the cover grid. Thanks to the cover grid 15 and the receiving reservoir 19 it is impossible to have small particles of tobacco/weed/dust ending up in one's mouth or throat.
• the opening 23 is in direct connection with the suction openings 27 in the suction piece 7 where the smoke can flow in straight lines 25 from the openings 23 to suction openings 27.
• Fig. 4 shows a second embodiment of the filter according to the invention.
• a partition 33 provided with holes 35 is present between the second end 13 of the inner wall 9 and the middle section 17 of the cover grid 1 .
