Abstract
A thermoformed filter rod having a tubular body of tobacco smoke filtering material which is open at one end and closed at the other end by a filtering plug of said tobacco smoke filtering material integral with the tubular body. The filter rod may be thermoformed from filamentary tow of plasticised cellulose acetate.
Description
The present invention relates to a kind of filter that for example is applicable to papirosi type cigarette.
Industrial once the trial filter was engaged with a hard cigarette or a pipe crimping in the past, but not success, because in actual production process, can not produce this bond reliably.
The invention solves this problem, a kind of cigarette filter is provided, this cigarette filter is made of the filter stick of a thermoforming.This filter stick comprises the body that a cigarette filter cigarette material is made, and body at least at one end is provided with opening, and body filters the plug sealing by one with the body all-in-one-piece, filters plug and is made by described cigarette filter cigarette material.Body can at one end be established opening, and the other end is with filtering the plug sealing.Also can be not like this, opening is all established at the body two ends, by the sealing of the filtration plug between two ends, in this case, two pipe end section is just arranged on the body, and they merge into an integral body by the filtration plug that becomes an integral body with them.In all cases, the length of filter stick body at least with the equal in length of filtering plug, can be compared to that to filter plug the longest most, such as, two to three times or more be multiple times than the length of filtration plug; Therefore body length can be 6: 1 or about 4: 1 with the length ratio that filters plug, but common 5: 2 suitable, particularly be 70 millimeters filter stick for length overall.
To the eye, the girth that passes through of whole thermoforming filter stick, shape are the same usually; Modal is that to pass through all be columniform outer surface.The cross section of tube cavity can be circular, also can not be circular, such as triangle or other polygonals, and cross or star (such as having 4,5 or 6 summits).
When on cigarette with filter tip, using filter stick of the present invention, become the mouth end of the filtration plug end of an integral body with it, and the openend on the body is towards cigarette cigarette.When the filter stick of filtration plug that the inside of plug or one is filtered in the end that has an one engages with the cigarette of spooling, preferably make the openend formation mouth end of body, formation papirosi cigarette with filter tip.With the cigarette of a weak point (as, the 25-50 millimeter) and one have short filtration plug (10-20 millimeter for example, or about 15 millimeters) the filter stick (for example 50-80 millimeter) of length make up, the cigarette with filter tip of Xing Chenging is fit to only to think to inhale at short notice several mouthfuls of cigarettes and for example only inhales the 2-5 mouth like this, the smoker of best 3-4 mouth, the tar reservation amount of this cigarette low (because inhale cigarette short), and provide to the smoker and to allow its satisfied cigarette (partly carrying out because filter mainly to be limited to filtering plug).
Filter plug and preferably form by the acetate fiber bundle thermoplastic of fiber or plasticising, but but also can be with the fiber of other hot briquetting or fibril (as the material of TPO) but or the filtering material of other hot briquetting, but as the foamed material that perforate is arranged of hot briquetting.Because filter stick is thermoforming, so guaranteed in follow-up operating process (when assemble) or during smoking, the body maintenance is enough solid as packing and/or with cigarette.
Can at high speed, stably produce the filter stick of thermoforming with the technological process of one way in-line arrangement in large quantity.In this production process, thermoformable filtering material (as the mixture of plasticized fibre bundle or fibre bundle) is sent to and by a barred body shaped device, this device heats filtering material, there is a central core shaft to thresh reciprocating motion vertically in this device, discharge the complete barred body of making by the heating of cigarette filter cigarette material continuously from the outlet of this device, barred body axially on, the filtration plug that body portion that filtering material is made and filtering material are made partly is alternately distributed.Can send common barred body overcoat to and pass through this barred body shaped device simultaneously, to produce the barred body of band barred body overcoat, even do not have overcoat on the barred body certainly, barred body is also very solid.Again to the band overcoat of continuous discharge or not with the barred body of overcoat from transversely cutting, cutting position is the place in the middle of place in the middle of the body portion and filtration plug part, to form the filter stick of single papirosi type, filter plug with the filter stick all-in-one-piece and be positioned at an end.Preferably only cut, so that between two open ends on the filtration plug of one and the body segment distance is arranged in the body portion of the barred body of discharging; The advantage of this embodiment is that it impels and produces pressure reduction and the reservation amount all immobilizes and filter stick that can duplication of production, because the filtration plug of the initial one that forms is kept perfectly, be not cut and from the embodiment that filters the plug cutting, cutting dislocation (being difficult in the actual production avoid) can make the length of filtration plug of each filter stick that continuously produces inconsistent, so pressure reduction and reservation amount are also inconsistent.
Wrapping overcoat to barred body, is the part of barred body moulding process, and the single filter stick that directly cuts down from the original barred body that continuously produces is connected the filter stick of band overcoat with an end Bao Huan usually normally with overcoat with cigarette by this way.The two ends that make single filter stick all are the openends of body portion, the filtration plug is in inside and become an integral body between two body portion openends and with them, the filter stick of this form has another advantage, because two ends are identical, filter stick with before cigarette is connected, needn't be to they orientations; On the contrary, for filtering the filter stick of plug in the end, they with the cigarette assembling before, necessary orientation, with the filtration plug of guaranteeing all filter sticks with respect to the cigarette that will connect at same end.
Can cut into complete twice or multilemgth barred body with continuously producing barred body earlier, and then this barred body is further cut, cut into single filter stick.For example, when using jacket to be connected with cigarette, can the whole barred body of a double-length near and between two cigarettes, make they on same axis to directly, make jacket extend and encase the end of the barred body and the cigarette adjacent thereto of double-length then, thereby the barred body of two double-lengths and two cigarettes are connected, cut open from the centre of the barred body of two double-lengths then and just formed two filter tip cigarettes.If the barred body two ends of double-length respectively have one to filter plug, the body of double-length filters between the plug and with them at two and forms an integral body, the cigarette with filter tip of making like this will be the cigarette with filter tip of papirosi type, and the openend of the body of this cigarette with filter tip is at the mouth end.Also having a kind of filtration plug of double-length barred body is double-length, and between two bodys, two openends of two bodys are relative, constitute the two ends of double-length barred body respectively, two bodys and a filtration plug constitute an integral body, the filtration plug of the cigarette with filter tip of making like this is at the mouth end, and the openend and the cigarette of body join.For fear of on complete filtration plug, cutting, to realize above-mentioned advantage, preferably all cutting positions all are placed on body portion, barred body from the original barred body that cuts continuous output to the cutting double-length is to make cigarette with filter tip, all the same, the body openend of the cigarette with filter tip of making like this is at the mouth end, and upstream extremity also is made of the body openend, and the filtration plug of one is between mouth end and upstream extremity.
When using jacket, the barred body overcoat of barred body self band can be arranged on double-length that initial production goes out or the multiple length barred body, can not have yet.From the double or multilemgth barred body of one, can cut out single filter stick, and these double-lengths or multilemgth barred body are also included within protection scope of the present invention.These multilemgth barred bodies are made of several independent filter sticks, and these filter stick ends and end connect into an integral body in the mode of mirror image.This integral body can have a filtration plug or every end that a body openend is arranged at every end.
Can select body portion as required or filter plug length partly, to produce papirosi type cigarette with filter tip with required filter effect.The degree of filtering also depends on filter cigarette properties of materials and compaction rate, and is subjected to the influence of tube cavity surface area less.
The length of filter stick of the present invention generally is 70 millimeter, but excursion is very big, for example from 20 millimeters to 90 millimeters.The length of filtering the plug part generally is from 8 or 10 millimeters to 50 millimeters, but as above pointed out can be compared to the body portion weak point most.Filter the plug part and generally be not less than 8 or 10 millimeters long (otherwise filter effect is just too low), generally also no longer than 20 or 25 or 30 millimeters (otherwise filter effect or anti-absorption are too strong); Particularly for the papirosi cigarette with filter tip, the length of body portion does not generally have technical meaning, can determine according to the total length of final products needs, and therefore as what point out above, can be that 2 or 3 (for example about 2-5) are doubly to the length of filtering plug.
The best relative thin of the tube wall of body portion of the present invention some, for example, from about 1/4th to eighth filter stick diameter or littler, so that the chamber of body approximately is that half of barred body outer dia is to 3/4ths or more.The tube wall of filter stick should have enough intensity, to prevent occurring depression in production, operation, storage and use.Such as, the thickness of body portion tube wall can be from 1 to 2 millimeter, preferably 1.5 millimeter.The peripheral diameter of filter stick is preferably between 7 and 9 millimeters, and is identical with common papirosi cigarette.
74 millimeters of a kind of filter stick length overalls that goes out constructed in accordance, there is the filtration plug of one 18 millimeters long the end, has the body of the one of one 56 millimeters long, approximately thick 1.5 millimeters of the tube walls of body.Its pressure reduction is 64 millimeters of water (this numerical value is as usual, the filter stick of a sealing is tested drawing).24.5 millimeters of this filter stick girths are connected with the cigarette of one 50 millimeters long, filter plug and withstand cigarette, constitute a kind of airproof cigarette with filter tip, its tar reservation amount 40%, nicotine reservation amount 38%.
The filter stick of the thermoforming that goes out produced according to the invention can be not with overcoat or have self barred body overcoat, this barred body overcoat closely is connected with barred body in the vertical.If overcoat is arranged on the filter stick, can use end Bao Huan that filter stick and cigarette are connected and composed cigarette with filter tip, the barred body overcoat of the filter stick of the cigarette with filter tip of Xing Chenging exposes like this, preferably can waterproof or do not absorb water, and the barred body overcoat is bonded on the lip when preventing smoking.No matter do not wrap overcoat on the filter stick, the barred body overcoat that self is still arranged, can be without end Bao Huan, constitute cigarette with filter tip on the cigarette and filter stick is joined to a common jacket, this jacket is wrapped whole filter stick and adjacent with it cigarette end, and this jacket does not preferably absorb water or can waterproof.The cigarette of this cigarette with filter tip generally is 30 or 40 millimeters long, but also can be increased to 90 millimeters long.Cigarette generally is rolled into common cigarette paper.
If make the barred body overcoat ventilation of the filter stick of thermoforming, just can reduce the tar discharge capacity of cigarette with filter tip.For example, when using end bag ring, barred body puts outward and can punch in advance, and like this, air can enter filter stick during smoking, thereby dilutes.Similarly, when using jacket, can punch in advance in the part that encases filter stick (if jacket with and filter stick between barred body overcoat in addition, the barred body overcoat also should be breathed freely).Can also be when assembling filter mouth cigarette, applicating laser technology is got passage outer the putting that is wrapped in the thermoforming filter stick.
The tar discharge capacity of cigarette with filter tip depends on the tar output in the tobacco component, the filter effect and the ventilation degree (if can ventilate) of filter stick.Organize in world standard under the standard conditions of ISO, the tar discharge rate can be from 1 to 65 milligram, but can be controlled in 15 milligrams.No matter how many tar discharge rates of papirosi cigarette with filter tip of the present invention is, the contaminated degree of filter stick mouth end has dropped to minimum.
