In traditional cigarette, between the filter stick formation paper 206 in adhesive is arranged on the part of the whole basically lower surface of tipping material 208 and nearly mouth end (or directly be set in the cigarette that does not comprise filter stick formation paper filter tip outside), and and the part of mouth end far away on lapping 190 (all with respect to being hinged with material) between.Yet among the embodiment of Fig. 1, adhesive preferably only applies and adds to the appointed area.For example, adhesive can apply addition near-end band 187 and far-end band 189.In the embodiment in figure 1, the tipping material is preferably diffusion tipping material.In the embodiment of diffusion tipping material, the diffusivity of tipping material will be similar to such as the standard cigarettes lapping of material 190 (for example, the diffusivity of about 2 cels or about 15 to about 80CORESTA basic porosity) and so on best or generally be used for the diffusivity of the tobacco charging similar type material on every side of cigarette.Preferred embodiment will have the diffusion tipping material and the porous filter stick formation paper of individual layer or not have filter stick formation paper.Diffusion tipping material will be greater than 0CORESTA and less than 100CORESTA, and preferable scope is about 5 to about 80CORESTA scope, and diffusivity is at least about 1 cel, preferably at least about 1.5 cel diffusivitys.These diffusivity measured values preferably are applied to and comprise any tipping material that prints prescription (for example, lip releasing agent (lip release), adhesive etc.).Diffusivity can use the technology such as those disclosed in people's such as Norman U.S. Patent Application Publication No.2005/0087202 to measure, and here cites this application with for referencial use.This has significant difference with typical tipping material, and typically being hinged with material can provide very little diffusivity or not have diffusivity (for example, about 0 cel is less than about 1 cel usually, or less than the basic porosity of about 10CORESTA).Yet, also known other highly porous tipping material (for example, 300-1200CORESTA is referring to the U.S. Patent No. 5,394,895 of authorizing people such as Muramatsu), it comprises by for example some materials of laser elevation perforation.

Diffusion tipping material 208 can comprise one or more perforation (for example laser beam perforation 210).In preferred embodiment, the air-flow in vertical circumferential surface district that passes the diffusion tipping material 208 of (and/or passing adhesive tape 187,189) between the adhesive tape 187,189 provides the feature of the main aerosol stream of expectation for the smoker.For example, than other all identical but with traditional low/cigarette that no diffusivity tipping material is made, the main aerosol stream at mouth end place can provide lower " tar " and CO content and lower CO/ tar ratio under FTC smoking condition.This effect, the percent dilution that can change cigarette filter 200 together with the fragrance concentration of main aerosol stream by the laser beam perforation by for example cigarette filter changes.

For the cigarette embodiment that comprises diffusion tipping material, the tipping material can be selected from many paperys or class paper material.In one embodiment, can use the typical lapping of the type that is generally used for comprising the tobacco charging.This lapping will comprise the diffusivity (for example, sometimes greater than 1 cel, preferably greater than about 1.5 cels, often be extremely about 3 cels of about 1 cel, and be generally about 2 cels) of expectation best.Preferably, in order to be used as the tipping material, papery or class paper products will be configured to comprise some features that are not present in usually in the tobacco lapping.For example, cellulose or polymer fiber (for example plastics) can be in manufacture process involved to and/or applied and be added to one or two surface to strengthen its structural integrity by the lip release characteristics that for example columnar strength, the wet power (for example from smoker's mouth) of moisture resistance and expectation are provided.(in the cigarette field, term " lip release " is meant the contact between the filter tip part that is coated with the tipping material of the lip that is configured to promote to discharge simply the people and cigarette, not obviously adhesion, and the lip releasable material of herein mentioning can comprise implement at present known and/or this area or the lip release formulation of any standard of exploitation in the future).

Diffusion tipping material can form braid, net sheet, paper, diaphragm and/or other suitable construction of desired diffusivity is provided.The thickness of tipping material and density can be determined in manufacture process or change after manufacture process so that the diffusivity of expectation to be provided, and general preferably less quality.With fiber, film, coating or other means that are used to provide desired characteristic to the processing of diffusion tipping material or in the tipping material, comprise that these can be confined to be hinged with the specific region of material.For example, lip discharges and/or moisture-proof can only provide on the mouth end parts recently.As another embodiment, fiber or provide or promote that the alternate manner of cylindricality intensity can be mainly or will provide in the zone across filter tip part and the junction of tobacco rods at the tipping material only.As a kind of mode of discharging of the lip that is used to provide expectation, the one or more film forming material such as nitrocellulose can be applied to be added to the tipping material or to cover in the tipping material.Be known in the art the moisture-proof paper and the paper material that comprise that those can provide the cylindricality intensity of expectation, and these paper and paper material can be used for easily or be suitable for within the scope of the invention.

Except net sheet, porous paper material or the another kind of paper material (for example polymer sheet) of typical lapping can be used to provide diffusion tipping material.Except diffusivity, desired characteristics will comprise that diffusion tipping material should provide acceptable " lip feel " that comprises that lip discharges to smoker (what contact with smoker's mouth at least is that part of).The structural strength that is enough between the conventional operating period (make, pack, transport, light and smoking) but filter tip and smoking bar are kept together should be provided.When contacting, should not reduce or form uncomfortable taste or texture with smoker's mouth.And, (if having) neutral or positive fragrance and sense of touch should be provided to the smoker.Organic and/or the inorfil of preparing in any mode in the known multiple mode in system paper and system film field and/or the mixture of particle can be used for forming diffusion tipping material.

Some or all of tipping materials can provide expectation, greater than the diffusivity of tradition tipping material.In certain embodiments, the thickness and/or diffusivity and/or the aroma profile of variable densityization of tipping material so that a kind of expectation to be provided.For example, paper that diffusance is very high or net sheet can be the same with typical tipping material thick or thicker, so that desired results intensity to be provided, also provide the diffusivity of expectation simultaneously.

Cigarette 174 also can comprise the second tipping material 250.The second tipping material 250 provides the skin of folding on the first tipping material 208 and surrounding the first tipping material.The outer surface of the tipping material or the first tipping material 208 in all of the inner surface of the second tipping material 250 or the part of selecting can be fixed to securely.Like this, in preferred embodiment, the second tipping material 250 is also folded on the adjacent area of the whole length of filter element and tobacco rods.For the embodiment shown in Fig. 3, two kinds of tipping materials are all along the substantially the same distance of zone extension of close the filter element of tobacco rods.For some preferable cigarette, the overall dimension of the first tipping material and the second tipping material all substantially the same (for example, those tipping materials have comparable thickness, width and length).In other embodiments, the smoking article of ventilation or air dilution can be provided with air dilution means, and such as a series of perforation 210, each perforation extends through external package material 250, interior tipping material 208 and filter stick formation paper wood 206.

Adhesive can use in making the cigarette process and be similar to those technology that are generally used for being hinged with the coating of material substantially and be applied to and respectively be hinged with material.Like this, one deck or two-layer tipping material can use conventional adhesive coated and be fixed, and the cigarette that so is provided with can be used for being attached to (individual layer or double-deck tipping) one deck or two-layer tipping material of cigarette.Yet adhesive can be applied to the jointing line of longitudinal extension of the second tipping material 250 or overlap (not shown, as to see the zone 600,616 of Fig. 6), but not its whole lower surface.Like this, the second tipping material 250 can be suitable for and apply being added to cigarette, and like this, the second tipping material can on purpose remove from cigarette.Therefore, gained be the filter tip cigarette that can accept quality can be by keeping second tipping material 250 complete the uses.In another embodiment, the second tipping material 250 can remove from cigarette, and the first tipping material 208 provides altered filter tip cigarette, and this filter tip cigarette also is acceptable quality, and aroma profile or other characteristic different but expectation for the smoker preferably will be provided.

In one embodiment, (for example, second) tipping material 250 outside can from cigarette, removing, this external package material is not configured to or is processed into to cigarette provides the air dilution, or is processed into the air dilution that cigarette does not experience height or level.For example, as shown in Figure 5, perforation 211 can only extend through filter stick formation paper 206 and interior tipping material 208.Like this, underlying or the first tipping material 208 can expose by the second tipping material of putting on removing allowing the dilution of high-caliber air, and this underlying or the first tipping material can be processed into to cigarette high-caliber relatively air dilution is provided.Like this, cigarette can be by suction and the second tipping material 250 is complete, so that the main plume that has more fragrance to be provided; Perhaps, the second tipping material can be removed, and so that main plume air dilution, few aromatic property to be provided, but can also reduce existence and/or its relative quantity of tar and CO.

Be used to provide the representative manner of this cigarette or the appropriate change that method relates to the method and apparatus that cigarette manufacturer is used, to provide so-called " band shape " cigarette for the market survey purpose.Promptly, will not surround band (for example about 1 centimetre of wide band) and apply and to be added in the tobacco rods of cigarette and the general area that filter element is adjacent to each other, the second tipping material is to surround on a part of tobacco rods length that band is applied on the whole length that is added to filter element and tobacco rods is adjacent with filter element.Like this, be provided with the filter tip cigarette that comprises one deck or two-layer tipping material, these tipping materials are positioned, apply and add and align in mode predetermined, expectation, this means that the location of every layer of tipping material and aligning are pre-determined by manufacturer.This equipment is particularly suited for two kinds of deposited cigarette that are added to of the tipping material layers that suitably align, there is not one deck tipping material (for example to design for the purpose that from cigarette, removes, because adhesive can be applied on the total inner surface basically of the external package material be added to indiffusible tipping material, perhaps also be configured to allow the adhesive of the diffusivity expected to be applied on the total inner surface basically of external package material of diffusion tipping material).Like this, the cigarette of of the present invention pair of tipping can have improved entity integrity.In addition, this equipment can be suitable for two kinds of deposited cigarette that are added to of the tipping material layers that suitably align, the skin of tipping material (for example designs for the purpose that removes from cigarette, by using the adhesive of release coat type, this adhesive can be applied is added to the total inner surface basically of external package material or the outer surface of interior tipping material).

With reference to figure 2, representational " twin " cigarette 400 is shown, it can be segmented so that two filter tip cigarettes 174,409 to be provided along chain-dotted line 2A-2A.The representative manner and the method for the cigarette that is used to provide preferred type are described with reference to figure 2 in addition." twin " cigarette 417 is provided.The sort of representative filter segment 417 comprises the filtering material 205 that is surrounded by filter stick formation paper 206.Two tobacco rods 190,428 align at each place, end of " twin " filter segment.Ground floor tipping material 208 (for example, so-called tipping material " pad ") is wrapped in around each parts of alignment, is hinged with material like this and surrounds the whole length of " twin " filter segment 417 and the part in its close corresponding region of filter segment of every tobacco rods 190,428 length.Typically, about 3 millimeters to about 4 millimeters of every tobacco rods length of ground floor tipping material 208 encirclements.Like this, provide so-called " twin " cigarette 400.For some preferred embodiment, ground floor tipping material is selected from one type tipping material, and is applied in one type mode and to add, material and mode all can with used the comparing of commercial filter tip cigarette manufacturing tradition.Perhaps, tipping material 208 can apply and be added with one or more gummed seam 187.This seam can be circumferentially (local or whole, comprise transverse to/perpendicular to longitudinal axis and/or with longitudinal axis at angle) and/or can vertically be provided with.

Fig. 2 A illustrates the cigarette 409 that cuts off from the twin cigarette of type shown in Fig. 2 2A-2A along the line with sectional perspective.Yet cigarette 409 only is provided with individual layer tipping material as shown or the second layer (for example, the tipping layer 250) removes from cigarette.As by shown in dotted line and the chain-dotted line, bonding seam 187 is arranged on by vertically and circumferentially (continuously and discontinuously) and is hinged with between material 208 and the filter stick formation paper 206.Specifically, by dotted line and the zone 187 shown in the chain-dotted line illustrate with the cardinal principle linear fashion along near the circumferential inner surface of every end and along substantially longitudinally inner surface contact the adhesive that is hinged with material.The tipping material can be the tipping material of diffusion.Usually use concrete the placement continuously and the whole bag of tricks of discontinuous bonding seam in process for making, and following also use new method (referring to, for example authorize people's such as Pipes U.S. Patent application No.12/101,529).Even now is placed adhesive and can be used restriction or reduce the deposited adhesive that adds the diffusivity in the zone of quilt, but what will appreciate that is that significantly restriction or minimizing not can be used for being hinged with on the part or all inner surfaces of material by deposited one or more adhesives that " spread during coating " that add diffusivity in the zone.The surface that this adhesive preferably provides porous or otherwise spreads, this surface allows air to flow through it, and the adhesion characteristic of expectation is provided simultaneously.In certain embodiments, the combination diffusivity of tipping material and adhesive can preferably greater than about 1.5 cels, arrive about 3 cels through about 1 cel of being everlasting greater than 1 cel, and general about 2 cels.

For the embodiments of the invention that comprise more than one deck tipping material, one or more flavorants will be involved also can be involved in multilayer in one deck tipping material at least.In the cigarette embodiment with multilayer tipping material layer, ground floor can comprise first flavorant, and the second layer can comprise second flavorant, wherein flavorant can possess identical, similar or different sensations, and wherein, if different, various sensations can be complementary or opposition.In one or more layers outer removable multilayer tipping material embodiment, the selection scheme that the smoker can have fragrance (for example, interior tipping material layer with first flavorant, with external package material layer with second flavorant, the smoker can select food utensil that two-layer product on the throne is arranged like this, it provides from the combination of internal layer flavorant and outer flavorant feels, or selects to remove the flavorant that has the outer of its flavorant and only experience interior tipping material layer).

Fig. 2 B illustrates cigarette 409 when 2A-2A along the line cuts off from the twin cigarette of type shown in Fig. 2 with sectional perspective.Yet cigarette 409 only is provided with individual layer tipping material as shown or the second layer (for example the tipping layer 250) is removed from cigarette.This embodiment comprises roughly vertically to apply the pattern of a kind of flavorant 287 that is added to outer surface with (continuous and discontinuous) multi-ribbon quilt that circumferentially is provided with.But tipping material 208 is basically along vertical circumference encirclement filter element 205 of filter element with by the smoking bar of lapping 190 along the proximal part covering of the close filter element 205 of vertical circumference of lapping.Specifically, flavorant band 287 represents by a partition, these partitions can see easily for the user, or is clearly or color-match for the tipping material, and they are difficult for seeing like this.The flavorant zone of dot-dash can be set in the tipping material or on, and can comprise capsule (for example, every chain-dotted line or every group of a plurality of chain-dotted line can be represented the capsule such as micro-capsule) or other flavorant device.Pattern can adopt any amount of other form and will be visible easily (for example, other banded pattern, grid pattern, crenellation pattern, geometry or non-geometrical pattern, image, letter etc.), and can be separately or with tipping material top on combinations of patterns ground apply be added to be hinged with material below.

In one embodiment, the first tipping material can be a kind of color or one type outward appearance (for example, outward appearance is white in color), and the second tipping material that preferably can remove from cigarette is the outward appearance of another kind of color or another kind of type (for example, be printed as the outward appearance with brown cork type or be printed on other sign).Other ornamental difference can by use a kind of smooth, the high grade of transparency, glossiness or be the tipping material of high glaze type and a kind of coarse, low transparency in appearance, the tipping material that is dim or glossy type in appearance provides.Other visual effect can be by using different figures to provide on two kinds of tippings each in the materials.Therefore, provide following mode and method, promptly by this mode and method, the smoker can select desired general cigarette outward appearance by remove the second tipping material in use from cigarette.

In one embodiment, the first tipping material may be selected to and comprises one type tactile characteristics, and the second tipping material that preferably can remove from cigarette can comprise dissimilar tactile characteristics.For example, interior tipping material can comprise be characterized as wavy, coarse, variegated, comprise folding line or wrinkle, have the outer surface of folded form or ripple type structure etc.; And external package material can comprise and is characterized as smooth, level and smooth etc. outer surface.In this respect, can use the outer surface of outside tipping material that suitable coating compounds agent (for example, lacquer) level and smooth, smooth sensation is provided.Alternatively, interior tipping material (for example can carry out the height perforation, outside from the bottom surface), impress, stand to fill texture (fillagraining) technology, be printed on coating (ink set outstanding or textured surface characteristic or starch-based material for example, are provided) or handle with the microparticle material in the adhesive films.For example, sugared crystallization, salt crystallization, can break contain fragrance microcapsule, cellulose fibre, calcium carbonate microparticle etc. can use the top layer of proper adhesive or figuratum top layer be fixed in the outer surface of tipping material.

The tipping material that the mouth petiolarea of different sensations is provided in the time of all can providing in being placed in smoker's lip also can be realized by using two types stacked tipping material.For example, the medial surface of external package material can be coated with suitable release coat, and the lateral surface of interior tipping material can be processed into to have and provides the fusible zone of expectation and the zone that the surface texture of expectation is provided to release coat.Therefore, provide following mode and method, promptly by this mode and method, the smoker can be by the sense of touch that the second tipping material selects the outer mouth end by cigarette to provide be provided from cigarette in use.

In one embodiment, the first tipping material may be selected to and comprises some other physical characteristic, and the second tipping material that preferably can remove from cigarette can comprise different physical characteristics.For example, the tipping material can be about gross, thickness, tensile strength, wet strength, moisture porosity, gas permeability, flexibility, general or overall hardness, general or overall pliability etc.

In one embodiment, the first tipping material may be selected to the ability that filter element is fixed to tobacco rods that comprises.This can provide by the material of selecting to have expectation surface characteristic, sealability, accepting the ability etc. of adhesive.The second tipping material may be selected to vision, sense of touch and the sense quality that expectation is provided.Like this, can provide extremely the perceptual quality of expectation and the cigarette of good entity integrity.

In one embodiment, the first tipping material may be selected to fragrance or the fragrance sensation with a type, and the second tipping material that preferably can remove from cigarette may be selected to fragrance or the fragrance sensation with another kind of type.On the one hand, can be by a kind of amount that is hinged with entrained fragrance of material or fragrance in the tipping material with different by the entrained amount of another tipping material.Therefore, for example, carrier band has the external package material of low-level relatively fragrance or fragrance that one type sensation can be provided; And having the interior tipping material of high-caliber relatively fragrance or fragrance can work as external package material, carrier band provides about the sort of fragrance and fragrance being sent to the effect of smoker's lip and mouth to smoker's lip and mouth when from cigarette, being removed.In certain embodiments, external package material can be suitable for preventing to be included between the tipping material, and the flavorant in the perhaps interior tipping material was overflowed before using cigarette and maybe can be suitable for hiding spices before the cigarette use.In use, the removable external package material of smoker is to expose flavorant.

Micro-capsule that Gutcho showed and miniature outside in the progress (Microcapsules and Other Capsules Advances) (1979) of micro-capsule He other capsule in 1975, having explained of being shown of wrapper technology (Microcapsules and Microencapsulation Techniques) (1976) and Gutcho be used to provide exemplary approach and the method for sealing the encapsulating material of flavorant such as little.The micro-capsule of exemplary types can have the diameter less than 100 microns, and often can have the shell of gel base, cyclodextrin base etc.Micro-capsule can be buied, and the microcapsule technology of exemplary types is that the micro-capsule shown at Kondo is handled and the 2,002 3 (3): the 25th of the AAPS that the people showed (U.S. pharmaceutical science man association) pharmaceutical science technology such as technology (Microcapsule Processing and Technology) (1979), Iwamoto and the United States Patent (USP) 3 of authorizing McGlumphy, 550,598 and authorize people's such as Takada 6, the type of explaination in 117,455.

In one embodiment, such as the releasable spices that is provided by the spices material of sealing or aromatic can be involved among any or both of the first and second tipping materials.For example, micro-capsule can be positioned between each layer of tipping material; And this spices can be exerted pressure or peel off and be released by outwards be hinged with material from interior tipping material.Alternatively, or in addition, capsule (comprising micro-capsule) can be positioned on the downside or its end face of tipping material, perhaps be embedded in the tipping material (and any combination, or be placed between tipping material and filter stick formation paper and/or the filter tip).As used at this, capsule or micro-capsule are meant can crush or otherwise can divide or decomposable composition, and it can form from the gel of for example epidermis, rigidity that have liquid, fragrance or that semiliquid nuclear (it can be involved in one or more capsules) or another seed capsules are constructed or semi-rigid housing.They can crushed or otherwise divide to discharge flavorant.Capsule can form of suspension be applied with adhesive and is added or involved in the tipping material.Capsule can be configured to by smoker's finger or by mouth contact (for example, the heat of mouth, pressure, humidity) and/or smoking process crushing or otherwise divided.

The exemplary use spices that is suitable for using in the present invention can be natural or synthetic, and the characteristic of these spices can be described as, but must not be restricted to fresh, sweet, the herbal medicine flavor, the candy flavor, the plant flavor, fruity or zestful.The particular type of fragrance comprises, but be not limited to vanilla, coffee, chocolate, cream, peppermint, spearmint, menthol, peppermint, wintergreen, lavender, cardamom, nutmeg, Chinese cassia tree, cloves, bitter fragrant skin, santal, honey, Jasmine, ginger, anise, Salvia japonica, licorice, lemon, orange, apple, pears, bitter orange, cherry and strawberry.Also referring to the tobacco flavorings that are used for the smoking product that the people showed such as Leffingwell (Tobacco Flavoring for Smoking Products), R.J. Rainolds Tobacco CO. (R.J.ReynoldsTobaccoCompany) (1972).Spices also comprises the composition that is considered to wetting agent, cooling agent or smoothing preparation, such as eucalyptus.These spices can be dexterously (that is, independent) or be composition (for example, spearmint and menthol, or orange and Chinese cassia tree) and be provided with.Combination spice can be used as mixture or is incorporated in the single capsule as the composition of a plurality of capsules.Flavor materials can cover the whole surface of tipping material.

In one embodiment, the tipping material can be included as the marketing or other purpose and the mark that is printed on.For example, sign on any one or two kinds of tipping materials or mark can help the correct cigarette of making of identification to help to recognize or identify the personation cigarette.As another example, the medial surface or the mark on the lateral surface of removable external package material can be used for discerning product, play the effect as certificate or ticket or recreation part etc.

In one embodiment, the tipping material can be used for strengthening the degradability such as the cigarette portions that has consumed of stub.For example, to be that the external package material of expecting can be removed after sucking cigarette for some organoleptic attribute is provided.That part of can from the remainder of stub, being removed dividually that from stub, is removed of external package material.Like this, in stub, be not hinged with the degradability that material can provide the enhancing of remaining stub parts.
