The accompanying drawing explanation
In order to make the present invention easily to understand and easily to implement, now will be by way of example, with reference to accompanying drawing, therein:
Fig. 1-8 have shown the cross-sectional side view of the amplification of tobacco product of the present invention;
Fig. 9-11 shows the enlarged drawing of watching from the non-filter end of tobacco product of the present invention; With
Figure 12 has shown the decomposition diagram of tobacco product of the present invention.
The specific embodiment
The applicant has been found that now, if produce such tobacco product, namely, it comprises the cigarette charge bar and comprises diluent and optional adsorbent and/or the first sheet material of diluent resistate, from the dilution by the diluent of elution of the ratio of the smoke components that produces this cigarette material and total tar yield, is minimized.Equally, the level of the smoke components that produces of cigarette material can reduce by the existence of the first cigarette material.Except the medium that comprises this diluent was provided, this first sheet material can serve as the winding up material in addition, and the whole length of parcel cigarette charge bar, therefore do not need other winding up material.Perhaps, can provide in addition the second sheet material.If the second sheet material has formed the winding up material in the first sheet material outside, the applicant has been found that the diluent that exists in the first sheet material can not cause on the second sheet material occurring ugly spot.
Therefore illustrated a kind of new and creationary scheme, solved problems of the prior art, and attempt the material of known lighted suction is improved.
If exist, this second sheet material can be the winding up material, and it comprises net material well known by persons skilled in the art or casting material (cast material), for example fiber gauze or reconstituted tobacco sheet material.It can in conjunction with coating, processing or chemical modification for example purpose be to reduce those of sidestream smoke or lower ignition proclivity.This second sheet material can with or without filler, this filler can be or can not be adsorbent and/or diluent resistate.
Typical situation is that winding up material material is continuous on the periphery of cigarette charge bar.Usually, this excellent end is without the winding up material; But such structure still falls within the scope of the present invention.
The thickness of this second sheet material can be 5-500 μ m, for example 10-300 μ m or 20-60 μ m.
This first sheet material can be any net material well known by persons skilled in the art, for example the tobacco sheet material of fiber gauze or regeneration.It can be in conjunction with coating, processing or chemical modification.This first sheet material can be with filler.It can comprise adsorbent and/or diluent resistate.
According to different embodiments, this first sheet material can extend jointly with the second sheet material, or it can only be provided on the one or more independent length part of cigarette charge bar.This first sheet material can and can be lighted between the material of suction at the second sheet material, and it can be called " inside " of the second sheet material, or it can be provided to the second sheet material with respect on the surface that can light sucked material, or " outside " of this second sheet material.According to an embodiment, the first sheet material has formed single sticking patch, and it only extends on the part of the second sheet material inner surface, round whole circumference.
When this first sheet material was in the form of a plurality of parts or sticking patch, such sticking patch can be any form.For example, such sticking patch can be in the form of a plurality of belts, its cigarette charge bar vertically on spaced apart.Perhaps, such sticking patch can be in the form of circle spacing bar, and this whole or partial-length along the cigarette charge bar extends.Still other, this sticking patch can be the combination of such belt and bar.The combination of described belt and bar can be positioned at the inner surface of the second sheet material, on outer surface or two surfaces.
In described tobacco product, use in the situation more than a sheet material, for example in the situation that exists a plurality of, sticking patch or full winding up material, each sheet material can be identical or different on forming from any one other sheet material.
The thickness of this first sheet material can be 5-500 μ m, for example 10-300 μ m or 20-60 μ m.But the material with larger thickness can be for some structure, for example bar extending longitudinally.
