body part

7,10 in opposite direction with the another hand-screw.In fact, the consumer possibly prefer tobacco rods 2 is remained on the appropriate location and rotates mouth end body part 7, but not maintains part 7 and rotate tobacco rods 2.

The chamber 17 that contains flavorant illustrates in greater detail in Fig. 5 a, 5b, 5c and 5d.As shown in the figure, the both sides of chamber 17 are provided with and keep

grid

20,21, and this maintenance grid construction becomes to allow smog to get into chamber 17 but prevents possibly drop out for the flavorant of granular form in the chamber 17.Shown in Fig. 5 c, intermediate member 9 has two pairs of locating holes 22, a pair of each of

grid

20,21 of being used for, thus and keep grid to be provided with being contained in the locating hole 22 said maintenance grid is fixed on the alignment pin 23 of appropriate location.The chamber 17 that contains flavorant can have the chamber size of about 0.03cc and keep

grid

20,21 can be suitable for providing about 3.5mm ²Draught area.The less big young pathbreaker in smog aperture cause passing the more high pressure drop of device 24 and thus the big I in said aperture be configured to realize desired pressure drop.

Fig. 6 shows alternative FLOW CONTROL device 24.As shown in the figure, FLOW CONTROL device 24 comprises and can overall be first and

second body parts

25,26 of tubulose by what molded plastics formed.As shown in the figure, first body part 25 comprises that two integrally formedly totally are the

tubular element

27,28 of cylindricality, and said member 27 has the diameter less than member 28.Second body part 26 has first and

second ways

29,30 on its opposite side, be configured to the bore hole 31 that holds member 27 slidably thereby limit.In this way, thus first body part, 25 grooves receive in second body part 26 and can rotate therein.The length of second body part 26 for example can be 6mm, and the length overall of device 24 can be 11mm.The diameter of device 24 can be 6.8mm.

As shown in the figure,

ways

29,30 further limits the smoke path 32 of passing body part 26, and said smoke path 32 is not opened to bore hole 31 when second body part has groove to receive the appropriate location.Consult Fig. 7 and 8, cutaway view has been shown among the figure, second body part 26 has the antetheca 33 that comprises smog aperture 34, and smog aperture 34 allows smog to get into smoke path 32.Smog aperture 34 for example can provide about 5.8mm ²Inlet area.

Fig. 7 shows the cutaway view of device 24, and wherein first body part, 25 grooves are received the appropriate location and rotated to primary importance.As shown in the figure, the smoke path 35 that in the annular wall 36 of this position smoke path 32 and bigger cylindricality tubular element 28, forms is aimed at, thereby vertical smog flow path of device 24 is passed in qualification.

Less tubular element 27 has annular wall 37 and antetheca 38, and said annular wall 37 and antetheca 38 contain the for example chamber 39 of the flavorant of granular form with annular wall 36 qualifications of tubular element 28.This chamber for example length can be about 8mm and can have the diameter of 3.5mm.Shown in Fig. 6 a, chamber 39 is in its back-end through totally sealing for the perforation end cap in the circular aperture 40 in the back that closely is coupled to said chamber 39.End cap 40 has smog aperture 41, said smog aperture 41 enough big in case allow smog pass device 24, but enough little so that prevent drop out chamber 39 and for example about 5.7mm can be provided of flavorant particle ²Total draught area.

As shown in the figure, annular wall 37 has peripheral part 42, and said peripheral part 42 has a plurality of smog aperture 43, and the remainder 44 of annular wall 37 forms the barrier of impermeable smog simultaneously.As shown in Figure 7, in primary importance, the impermeable part 44 of wall 37 limits the inwall of smoke path 32, thereby prevents that smog from getting into the chamber 39 that contains flavorant.With first body part, 25 Rotate 180 degree to the second place shown in Figure 8, can be alignd with passage 32 in the smog aperture 43 in the peripheral part 42, thereby the inwall of permeable smog is provided for passage 32.In this way, smog can flow from passage 32 and pass aperture 43 and get into chamber 39.Preferably, aperture 43 provides about 8mm ²Total draught area.

As shown in Figure 8, in the second place, passage 32 is not aimed at passage 35, thereby blocks the end of said passage 32 through the annular wall 36 of member 28.Thus, in the second place, the unique path that smog can be walked is through aperture 43.

Arrow 45 among Fig. 8 shows the path that passage of smoke is in the device 24 of the second place.As shown in the figure, smog gets into device 24 and admission passage 32 through smog aperture 34.Smog becomes horizontal direction to pass smog aperture 43 and gets into the chamber 39 that contains flavorant along the longitudinal axis with device 24 subsequently.Smog vertically passes the chamber that contains flavorant 39 that has wherein added flavouring agent subsequently.The smog that adds flavouring agent passes subsequently and flows out the aperture 41 in the end cap 40.

Because smog is along laterally getting into chamber 39, so smog and particle can interactional surface area only receive the size restrictions in smoke permeable zone 42 above that, rather than situation about flowing as vertical smog is limited by the cross-sectional area of device 24.Therefore, with the contrast that vertical smog flows, can increase interactional surface area and strengthen the local flavor that transmits.

In addition,

smog aperture

43 and 41 big I are set to provide in the second place draw resistance of expectation.Thus, for example, thereby smog aperture 43 can be made into and makes the pressure drop of passing the device 24 that is in first and second positions have perceptible difference enough for a short time, and then provides different smoking to experience according to the selected consumer that is oriented.

Aperture 41 in the end cap 40 can be suitable for the remainder that allows flavouring agent to move to cigarette 1 and possibly move to other cigarettes in the Cigarette pack, thus before the smoking-for example be that cigarette provides the smell that adds flavouring agent when opening cigarette.As stated, though possibly not expect in some cases so, some consumer possibly prefer providing the smell and this right to choose that add flavouring agent to provide through device 24 for their cigarette before in smoking.

Advantageously, first body part 25, second body part 26 and end cap 40 are processed by molded plastics and can be used known injection moulding technology manufacturing.With hand or with

machine part

25,26,40 grooves to be received the assembly ware 24 of coming together be very easily.

Many remodeling and modification will be tangible concerning one of ordinary skill in the art.

For example; Although filter cell 3 is described as having the plug 5 of FLOW CONTROL device 4 that is positioned at its mouth end and the cellulose acetate tow that is positioned at its tobacco end in the above; But alternatively or additionally, the plug of cellulose acetate tow can be positioned on the mouth end of filter cell 3.Thus, alternatively, filter cell 3 can be included in the FLOW CONTROL device that every end is all located the plug of cellulose acetate tow.Cellulose acetate tow plug, FLOW CONTROL device and tobacco rods can use plug wrap of wrapping paper-for example and/or tipping paper to keep together.Wrapping paper can comprise the porous circumferential hoop so that allow filter cell to rotate.Wrapping paper can pre-punching or alternatively can after having packed filter cell, be carried out laser beam perforation.

Further, though top the description uses flavouring agent to add local flavor as smog, can come optionally to adopt any smog modification through using suitable smog modifier.For example, on the basis of flavorant or as the substitute of flavorant, can use wetting agent to change the water content of smog.

As in this use, that term " flavouring agent " and " flavorant " mean is that local statues allow, be used in the taste that forms expectation in the product or the material of fragrance.They can comprise the licorice of extract-for example; Hydrangea; Day raw white skin flower bud of lily magnolia lily magnolia leaf; Chamomile; Faenum graecum; Cloves; Menthol; Cornmint; The anise seed; Chinese cassia tree; Vanilla; Wintergreen; Cherry; Berry; Peach; Apple; Reach nurse platinum (Dramboui); The bourbon; Scotland; Whiskey; Spearmint; Peppermint; Lavender; Cardamom; Celery; Bitter skin is fragrant; Nutmeg; Santal; Bergamot; Fish pelargonium; Honey essence; Attar of rose; Vanilla; Lemon oil; Orange oil; Cassia; Carum carvi; Ke Nake; Jasmine; Ylang-ylang; Sage; Fennel; Many fruital; Ginger; Anise; Coriandrum; Coffee or from the peppermint oil of any Mentha species; The local flavor screening agent; Bitterness receptors position blocking agent; The acceptor site reinforcing agent; The Sucralose of sweetener-for example; Acesulfame potassium; The aspartame; Asccharin; Cyclamate; Lactose; Sucrose; Glucose; Fructose; The chlorophyll of D-sorbite or sweet mellow wine and other additives-for example; Mineral matter; Plant or flavorants.They can be copy, artificial synthetic or natural component or their mixture.They can be any suitable forms, for example oil, liquid or powder.
