Definitions

  • a flow control device for a smoking article to control flow of an aerosol for example smoke, to be imparted with a flavourant.
  • a cigarette with a rotatable section that allows smoke to pass to the user either directly or through a material impregnated with menthol to impart a flavourant is described in EP 0 317 154.
  • the smoke is drawn through semi- cylindrical passageways that are selectable by axial rotation of the section.
  • the passageways have substantially different impedances to flow since one of them is empty and the other contains the menthol impregnated material and so the resistance to drawing smoke experienced by the user varies according to the angle of rotation of the section.
  • an inventive flow control device for a smoking article to control flow of an aerosol therefrom, comprising an inlet and an outlet for the aerosol, a body of flavourant material, the body having an exterior surface to release a flavourant into the aerosol, and first and second members rotatable relative to one another between a first position in which the aerosol sweeps over the surface of the flavourant material when passing from the inlet to the outlet to entrain flavourant released from the flavourant material, and a second position in which at least some of the aerosol passes from the inlet to the outlet without sweeping over the surface of the flavourant material.
  • the device can be configured so that the proportion of the flow of aerosol from the inlet to the outlet that passes over the surface of the flavourant material progressively changes as the members are moved between the first and second positions. Since the aerosol can be swept over an exterior surface of the flavourant material rather than being drawn through it, the resistance to drawing aerosol through the device can be arranged to be substantially the same in the first and section positions of the members.

  • a smoking article 1 in the form of a cigarette comprises an aerosol generating device 2, in this example a combustible rod of tobacco or tobacco like material, provided with a filter 3 through which a user can draw smoke.
  • the filter may be of any suitable design, for example cellulose acetate tow in a plug wrap.
  • the filter may include additives or multiple sections of different materials.
  • a flow control device 4 is provided on mouthpiece end 5 of the smoking article 1 to selectively control flow of smoke to the user.
  • the flow control device 4 includes first and second bodies of flavourant material 6-1 , 6-2 and by rotation of the control device 4, the user can select the amount of flavourant that is imparted into the smoke.
  • the flow control device comprises first and second generally tubular members 7, 8 that are mounted for relative rotation on common axis X-X'.
  • the first member 7 has a peripheral flange 9 that is rotatably and slidably received within the second member 8 such that the members 7, 8 are contiguously arranged.
  • the first member 7 includes a cylindrical outer wall 10, an axial rod 11 and fins 12-15 which extend radially from the rod 11 to the outer wall 10 so as to divide the interior into sectors, in this example four quadrant sectors S1 -S4.
  • the sector SI acts as a receptacle for the body of flavourant material 6-1 and the diametrically opposed sector S3 constitutes a receptacle for the body of flavourant material 6-2.
  • the sector SI is closed at one end by a base 17 that extends between the fins 12 and 13 and the part of the sidewall 10 within the sector SI .
  • the fin 13 has an edge 18 which is inclined to the axis X-X' to provide a re-entrant region through which smoke can flow from the sector S2 into sector SI as will be explained in more detail hereinafter.
  • the body of flavourant material 6-1 is of a shape to fit snugly within the receptacle provided by the sector SI and has an inclined exterior surface 19 which has an edge generally coextensive with the re-entrant edge 18 of fin 13.
  • the sector S3 is similarly configured to provide a receptacle that receives the body of flavourant material 6-2 which is of same shape as the body of material 6-1.
  • the sector S2 includes an opening 20 that receives smoke from the filter 3 and the sector acts as an interior passageway through which smoke can pass to the user.
  • the sector S4 is configured in a similar fashion with opening 21 to receive smoke from filter 3.
  • sectors S5-S8 which can be selectively aligned with sectors of the member 7 by rotation about the axis X-X'.
  • Sectors S6 and S8 include openings 22, 23 that act as outlets for the smoke.
  • the sector S5 includes a radial fin 24 that protrudes in the axial direction and has an inclined edge 25 that can be aligned in close contact with inclined edge 18 of fin 13 of the first member 7.
  • the sector S5 also includes an inclined surface 26 that is configured to fit closely over the inclined surface 19 of the body of flavourant material 6-1.
  • the sector S7 includes a similar arrangement with radial fin 27 and inclined surface 28 configured to fit over the exterior surface of the body of flavourant material 6-2.
  • the second member 8 can be configured in a first rotary position relative to member 7 as illustrated in Figure 5A.
  • smoke can enter the opening 20 in sector S2 of the first member 7, pass around the fin 24 and surface 26 which, in the first position, are disposed in the second quadrant S2 so that smoke can be drawn through the outlet 22 in sector S8 after having been swept across the exterior surface 19 of the body of flavourant material 6-1.
  • flavourant is imparted into the flow of smoke supplied to the user through outlet 22.
  • smoke can be drawn through sector S4 of the first member 7 to pass over the exterior surface of the second body material 6-2 in sector S3 and be drawn by the user through outlet 23 in sector S6.
  • the member 8 has been rotated fully to a second stop position in which the outlet 21 becomes fully aligned with inlet 20 and similarly, the inlet in sector S4 becomes aligned with outlet 22 so that the smoke can pass directly through the flow control device without receiving any flavourant.
  • the inclined surface 24 overlies the inclined surface 19 of the body of flavourant material 6-1 completely.
  • the smoking article When manufactured and supplied in packs to the user, the smoking article may be supplied with the first and second members 7, 8 in the second position shown in Figure 5C since, in this configuration, the flavourant material 6-1, 6-2 is fully encapsulated by the device, with the inclined surface 26 of the second member 8 overlying the corresponding inclined surface 19 of the body of flavourant material 6-1 , which reduces the rate that the flavourant dissipates from the body of material 6-1. Similar comments apply to the arrangement of surface 28 and the body 6-2 of flavourant material.
  • a sealing medium such as a wax or oil may be applied during manufacture between the inclined surfaces 26 and 19 so as to provide a seal which prevents or reduces the release of flavourant prior to smoking.
  • the seal may be broken by the user twisting the members 7 and 8 relative to one another as previously described or the sealing material may be heat sensitive so that the seal becomes broken by the heat of the cigarette when lit by the user.
  • the body of flavourant material 6-1 , 6-2 may comprise cellulose acetate tow impregnated with liquid menthol.
  • other flavourants may be used along with different supporting matrices. It will be seen that the smoke is caused to sweep over the surface 19 of the body of flavourant material 6-1 rather than being forced to flow through the body of material itself. In this way, the impedance to smoke flow does not vary
  • the flow control device 4 may be attached to the filter 3 shown in Figure 2 by means of tipping paper 29 which may also locate the filter onto the tobacco rod 2.
  • the tipping paper may be provided with a circumferential line of weakness (not shown in Fig. 1 or 2) in the region of coupling between the first and second members 7, 8 to allow the members to be initially held in the second position shown in Figure 5C, after which the user may break the tipping paper along the line of weakness by twisting, so as to allow rotation of the second member 8. In this way, the strength of flavourant provided into the smoke can be adjusted selectively during use.
  • a second embodiment is illustrated in Figures 6 to 11.
  • a smoking article 1 includes a tobacco rod 2 filter 3 and a flow control device 30 assembled together in a similar fashion to the embodiment of Figures 1 and 2.

  • the menthol plug 33 is received within a cylindrical receptacle 34 having a generally cylindrical receptacle wall 35 that is coaxial with common axis X-X'.
  • the receptacle 34 is coupled by four radial spokes 36 to a circular rim 37.
  • the spaces between the spokes 36 provide inlets 38-1 , 38-2, 38-3 and 38-4 for smoke from the filter.

  • the inner cylindrical coupling member 41 also includes openings 45-1 , 45-2 that can be selectively aligned by rotation with the windows 39-1 , 39-2 to release flavourant into the passing smoke and also to shield the windows 39 from smoke passing through the device to prevent the release of flavourant.
  • a sealing medium such as a wax or oil may be applied during manufacture to the underside of the coupling member 41 so as to provide a seal over the windows 39 which prevents or reduces the release of flavourant prior to smoking, the seal being breakable on rotation of the first and second members 31 , 32.
