Description
Technical field
The present invention relates to make the smoking article coil paper of tobacco amount of visible sidestream smoke minimizing.
Background technology
Developing the few low sub-flow smoke cigarette of sidestream smoke generation in recent years.Usually, whether the generating capacity of so actual sidestream smoke of cigarette reduces with so-called fish tail method definite.The fish tail method is opened to wait in the communique for flat 10-81 number the spy and is recorded and narrated with reference to figure.Briefly, the fish tail method is used the smoke-box with fishtail open lower end portion.At the top of smoke-box installation microscope formula filter (diameter 44mm).Ratio from the upper end of this smoke-box with 3 liters/minute sucks air, makes cigarette spontaneous firing specific length simultaneously in the bottom of smoke-box.Make this moment on the inwall of particulate matter in the secondary plume of generation, measure its quality attached to micro-mirror filter and smoke-box.Promptly at first obtain the quality difference of deducting original micro-mirror filter from the quality that captures the micro-mirror filter behind the particulate matter, then, extract out attached on the micro-mirror filter and the particulate matter of smoke-box inwall with various solvents, measure absorbance, calculate quality attached to the particulate matter on the smoke-box inwall by the ratio of each absorbance that obtains and the quality (difference) calculated previously attached to the particulate matter on the micro-mirror filter.The value that adding attached to the quality of the particulate matter on the micro-mirror filter with attached to the quality of the particulate matter on the smoke-box inwall of obtaining like this calculated together is as the sidestream smoke amount (mg/cig) of each root cigarette.In addition, in this method, measure the spontaneous firing needed time of specific length, the value representation that is removed every sidestream smoke amount the time that determines with this is the sidestream smoke amount (mg/min) of unit interval.The sidestream smoke amount of the unit interval that obtains can be used as the sidestream smoke amount of seeing with the surface in the exploitation of existing low sub-flow smoke cigarette approximate.
In addition, also proposed without quality determination, and the scheme of the device of the sidestream smoke amount of or instantaneous measurement this cigarette continuous with optical means (spy opens flat 3-120444 communique).This Optical devices emission light beam makes it see through the sidestream smoke that sends by the cigarette of combustion chamber internal combustion, measures the intensity of the light beam that sees through sidestream smoke.This beam intensity that determines is corresponding with the concentration of sidestream smoke, thereby reflects the amount of all particulate matters.
, even in the quality evaluation of all particulate matters of usefulness as the fish tail method obtains cigarette with degree low sub-flow smoke amount, in fact examine with observing during smoking, the sidestream smoke amount also has difference sometimes.The clear and definite sidestream smoke amount that is produced by the quality of all particulate matters may not be with relevant with the observable sidestream smoke amount of eye.Because also corresponding with sidestream smoke concentration with the sidestream smoke amount of above-mentioned optical method measuring, thus also we can say with a usefulness observed sidestream smoke amount may not be relevant.
The smoking article that cigarette is such we can say that the quality of not only expecting all particulate matters is little, and expects that its sidestream smoke amount of actual visual observations is also few.
Thereby, the object of the present invention is to provide a kind of smoking article coil paper, it can reduce with eye observed sidestream smoke amount (being also referred to as " amount of visible sidestream smoke " in this manual).
Summary of the invention
The present inventor studies in order to achieve the above object and painstakingly, found that by calcium carbonate that mixes specified quantitative in coil paper and the combustionregulator of mixing special ratios, and amount of visible sidestream smoke is declined to a great extent.The present invention is found to be the basis with this.
Promptly the invention provides the coil paper that smoking article that a kind of amount of visible sidestream smoke that makes tobacco reduces is used, wherein contain calcium carbonate 30g/m
2More than, the ratio that contains combustionregulator surpasses 3% (quality).
In the present invention, combustionregulator is preferably selected from the group who is made up of potassium citrate and natrium citricum.
In the present invention, preferably the content of ashes of the superficial layer of at least one side of coil paper is below 35% (quality), and the content of ashes of the superficial layer of coil paper top and bottom is preferably all below 35% (quality).

The specific embodiment
To illustrate in greater detail the present invention below.
The present invention be used for smoking article with the paper pulp of coil paper by being used for formations such as the flax paper pulp of general smoking article (particularly cigarette) with coil paper, wood pulp.The amount of paper pulp is practical in the amount that guarantees the intensity that papermaking or cigarette are required, preferably 20～50g/m
2
Smoking article of the present invention contains calcium carbonate above specified quantitative with coil paper in above-mentioned paper pulp, and adds the combustionregulator that surpasses specific ratio.Calcium carbonate is pressed 30g/m
2～50g/m
2Amount mix, combustionregulator in coil paper with the mixed more than 3～15% (quality).Calcium carbonate quantity is discontented with 30g/m
2The time and (or) the ratio less than 3% (quality) of combustionregulator the time, can not give full play to the effect that reduces amount of visible sidestream smoke.
Calcium carbonate adds with particle shape, and its particle diameter can be from cost, and the viewpoint of papermaking is set out and suitably selected easily, preferably 0.02 μ m～10 μ m.
In addition, coil paper preferably has 50g/m
2～100g/m
2Quantitatively.
Preferably use alkali metal citrates as combustionregulator; Good especially is potassium citrate and natrium citricum; They can use alone or in combination together.
But, since the filled paper made from fourdrinier machine when forming ply of paper from the dehydration of wire one example, compare with the felt side, the filler of wire one side tails off, the filler in the last paper of paper thickness direction (being also referred to as the z direction) and the distribution of fiber produce skew, form to have the two faced scraps of paper.Though this dual character becomes shortcoming in printing quality with aspect the paper characteristic sometimes in the printing field, in existing coil paper, this dual character is good on the convergence this point of ash when cigarette combustion, and other influence is a problem hardly.
; when containing the coil paper of very many fillers like that with existing fourdrinier machine manufacturing the present invention; come off when making cigarette at the filler that contains in a large number on the surface of felt side, problem such as take place easily that the paper powder damages and wraparound is bad becomes the main cause of overslaugh cigarettes at high.
In order to address the above problem, be necessary when former state keeps in the paper contained in the coil paper amount of filler, only to reduce the filler that distributes near surface.Only reduce the device of the filler that distributes near surface when keeping amount of filler in the contained paper of coil paper, can enumerate the papermaking apparatus that forms ply of paper by double side dewatering type wire parts as former state.Can enumerate that to have so-called double side dewatering type wire parts are composite wire formula wire parts, composite wire machine and make the paper machine of the wire parts that are called as open upper part type wire or mixed type metal silk of a part of composite wireization of fourdrinier machine.Because the dehydration when ply of paper forms in general fourdrinier machine is only carried out in wire one side, and two sides wire formula is by forming ply of paper by two dehydrations wiry that connect up and down at the paper grade (stock) paper stock, so the filer content on coil paper surface is tailed off.With respect to the coil paper made from general fourdrinier machine, the filer content of felt face is the highest and reduce gradually to wire surface, the difference of the filer content of the inner and superficial layer of the coil paper ply of paper made from composite wire formula paper machine is little, and the difference of the filer content of ply of paper integral body and each layer filer content becomes quite little.In addition, the present invention will be from the coil paper surface be defined as superficial layer to 18～20% part of the suitable total quality of thickness direction quality, its content of ashes is expressed as the content of ashes of superficial layer.Two of the surface of coil paper and the inside surfaces generally when making with existing fourdrinier machine, are called felt side and wire side in addition; When making with composite wire formula paper machine, be called upper metal silk side and bottom metal silk side, but the present invention is called upper side with felt side and upper metal silk side, wire side and bottom metal silk side are called bottom side.Preferably the upper side of coil paper and the content of ashes of at least one side's superficial layer of bottom side are lower than 35% (quality) in the present invention, and the content of ashes of the upper side of coil paper and the superficial layer of bottom preferably is lower than 35% (quality) entirely.
At this, the content of ashes of superficial layer can be cut apart the coil paper test portion for several times at thickness direction, asks from the test portion surface content of ashes at 18～20% the superficial layer that is equivalent to total quality of thickness direction by JISP 8128.Roughly as follows.
Take the test portion quality measurement of 40mm * 200mm from coil paper.Paste paper tape (wide 50mm, model is tesa # 4267) on the surface of test portion and make do not have air layer to the end, cut after the part of exposing from test portion pastes paper tape, add that from pasting paper tape load is bonding well from the end of test portion.Measure the quality that is stained with the test portion of pasting paper tape once more and ask the quality of pasting paper tape.Then, at the reverse side of test portion also stickup paper tape, utilize the bonding force of pasting paper tape to be divided into two parts being clipped in the test portion of pasting in the paper tape.Cutting apart is that the T font is peeled off, and promptly with to be clipped in the test portion of pasting in the paper tape vertical, carry out level at leisure with certain speed and peels off.On the release surface of peeling off for the first time test portion, stick again and paste the same repeatedly order of paper tape, the quality that proceeds to superficial layer become original test portion quality 18～20% till.Each test portion of the superficial layer that obtains gathers 10 points, applies heat-flash with bonding paper tape at 900 ℃, is that standard is asked content of ashes with JIS P 8128.Revise with the content of ashes of pasting paper tape, be expressed as the content of ashes value of superficial layer.In addition, different therewith, the content of ashes of the test portion before cutting apart is expressed as full content of ashes value.
Smoking article of the present invention (particularly cigarette) has significantly reduced the amount of visible sidestream smoke of tobacco than existing coil paper with coil paper.Though the mensuration of amount of visible sidestream smoke can be checked by human body, in order simply to use the amount of visible sidestream smoke determinator of being willing to announcement in 2000-268910 number the spy.
Fig. 1 is special schematic perspective view of being willing to the amount of visible sidestream smoke determinator of 2000-268910 number announcement, and Fig. 2 is the block diagram that schematically illustrates this amount of visible sidestream smoke assay device structures.
As depicted in figs. 1 and 2, this amount of visible sidestream smoke determinator 10 comprises: the spontaneous firing chamber 11 of smoking article, visible light illumination unit 12, it is used for to being created in the visible beam of irradiation regulation on the actual vertical direction of flow direction of the sidestream smoke that rises naturally spontaneous firing chamber 11 with relative spontaneous firing by smoking article; Scattered light intensity detecting unit 14, its be used to detect by sidestream smoke produce with the actual vertical direction of direction of visible beam on the scattered intensity of scattering as the index of amount of visible sidestream smoke.
In the space of 11 bottoms, spontaneous firing chamber that impale with louver(-vre) 112～115, unshowned bead in the blank map, form air-flow rectification layer, so that flowing of the sidestream smoke SSS that rises that is produced by the spontaneous firing of smoking article is not disorderly in spontaneous firing chamber 11.The upper end of spontaneous firing chamber 11 is open.Can be provided for spontaneous firing chamber 11 in this open end and carry out the hood 15 of exhaust.The exhaust of this spontaneous firing chamber 11 must not have the degree of materially affect to carry out in the spontaneous firing to smoking article SA.When carrying out exhaust, rectification filter 16 is installed in the open end, top of best cross-section spontaneous firing chamber 11, makes the sidestream smoke SSS of rising mobile naturally spontaneous firing chamber 11 in of not upsetting that spontaneous firing by smoking article produces.At the top of hood 15 exhaust duct 151 is set, it is connected with not shown gas extraction system.
Visible light illumination unit 12 is located at the outside of spontaneous firing chamber 11, in example shown in Figure 1, is located at the outside of the spontaneous firing chamber 11 sidewall 11b relative with the sidewall 11a that inserts smoking article SA.At the sidewall 11b relative visible light penetrating window 116 is set partly with visible light illumination unit 12.Visible light illumination unit 12 is equipped with not shown visual light source, and the sidestream smoke SSS that rises naturally in spontaneous firing chamber 11 that the spontaneous firing by smoking article SA is produced sends visible beam VLB to the actual direction vertical with its flow direction.As visual light source, just there is not special restriction as long as can send visible light.As using visible light laser, visual light emitting diode, Halogen lamp LED etc., the representational A light source that can use International Commission on Illumination's regulation.
The section that the visible beam VLB that sends from visible light illumination unit 12 has essence even make that having some to rock also for the sidestream smoke SSS that rises naturally can fully cover in spontaneous firing chamber 11, and can shine visible light.For example, visible beam VLB can have rectangular section, and it has width W (Fig. 2) on the direction vertical with direction of illumination, and considers people's the visual field, the visual field when estimating by people's sense organ is consistent, with the in fact vertical direction of the direction of illumination of visible beam VLB on have height.Width W is preferably in the shaking amplitude that equals visual sidestream smoke SSS on the direction vertical with the direction of illumination of visible beam at least.In addition, the section of visible beam is not limited to rectangle, also can be ellipse, circle etc.Give the shape of such visible beam, can be with having with the cover of visible beam section corresponding opening or using the known methods such as lens combination that are combined into by convex lens and concavees lens.
Relative with visible light illumination unit 12, the outside in spontaneous firing chamber 11, in example shown in Figure 1, in the outside of routine wall 11a light absorption units 13 is set preferably, it is used for, and influence ground all absorbs, removes the light that is sent and seen through sidestream smoke SSS by visible light illumination unit 12 to measuring not.Part at the sidewall 11a relative with light absorption units 13 is provided with visible light penetrating window 117.
Scattered light intensity detecting unit 14 is located at and the outside from the spontaneous firing chamber 11 of the irradiation light vertical direction of visible light illumination unit 12, is located at the outside of sidewall 11d in example shown in Figure 1.The part of the sidewall 11d relative with scattered light intensity detecting unit 14 is provided with visible light penetrating window 118.Scattered light intensity detecting unit 14, as narrating, be to detect at irradiation sidestream smoke SSS and the unit of the intensity of the scattered light of scattering (below be called 90 degree scattered lights) SLV on the direction vertical in fact in by the light of its scattering with the direction of illumination of visible beam VLB.Scattered light intensity detecting unit 14 has the known optical system (not shown) of scattered light SLV optically focused that is used for 90 degree is housed, and the degree of 90 behind optically focused scattered light SLV is converted to the light/electrical switching device (not shown) of signal of telecommunication output.Preferably use the photomultiplier that light is transformed into voltage signal as light/electrical switching device.After voltage signal after this conversion such as the A/D conversion, can carry out data sampling with microcomputer.Obtain the interval of data and obtain the time and can set arbitrarily,, can in one minute, carry out 300 mensuration as the interval of representative with 0.2 second.
Intensity and the amount of visible sidestream smoke of these detected 90 degree scattered light SLV have extraordinary correlation, and detected 90 degree scattered intensity are strong more, can judge that amount of visible sidestream smoke is relatively many.In addition we know, the total amount of the particulate matter of 90 degree scattered intensity and sidestream smoke is uncorrelated.
In order to prevent respectively between visible light illumination unit 12 and visible light penetrating window 116, reach stray light outside between scattered light detecting unit 14 and the visible light penetrating window 118 between light absorption units 13 and the visible light penetrating window 117 and inject, the case 17～19 of covering outer stray light preferably is set from the visible light penetrating window.
