Abstract
The utility model provides a dual-cavity cigarette filter tip with intercept points, which comprises a filter core and forming paper of an ordinary cigarette filter tip. A circle of dual-cavity cellulose paper is also arranged on the periphery of the filter core and in the forming paper. The cellulose paper comprises five sections, i.e. a first groove section, a first cavity section, a second groove section, a second cavity section and a third groove section in sequence. The groove sections adopt cellulose paper sections with arc-shaped grooves, bevel-shaped grooves or arc-bevel combined grooves, and the cavity sections adopt flat cellulose paper and are respectively one half to one twentieth as long as the cigarette filter tip. The three groove sections have the same outside diameter of 5.0-8.0mm, and the outside diameter of the cavity sections is smaller than the outside diameter of the groove sections and is respectively 0.05-1mm. Each groove section can be internally provided with protruding intercept points, the height of the intercept points is no more than the width of the grooves, and the length of the intercept points is smaller than the length of the groove sections. The cigarette filter tip has a novel structure, harmful substances in flue gas can be intercepted more effectively due to the two cavity sections and the intercept points, the flue gas can be condensed fully, and the taste of cigarettes can be improved.
Description
Technical field
The utility model relates to the cigarette filter tip of cigarette, refers in particular to a kind of two-chamber section cigarette filter tip that contains alternate groove section and cavity segment on cellulose paper.
Background technology
Cigarette filter tip is the filtering material of cigarette, and the structure of cigarette filter tip and filter effect have remarkable influence to the quality of cigarette.Filter tip commonly used is made of filter core and shaping paper, high-grade cigarette filter tip in the filter core periphery, shaping paper the inside also has a circle cellulose paper, but common cellulose paper is remarkable not enough to the crown_interception of flue gas.
Application number is that CN01238106.3 and application number are that the patent specification of CN200520022337.9 discloses a kind of " groove filter rod " respectively, outside filter core, in the shaping paper integument is arranged, and longitudinal groove is arranged on integument.This groove is common continuous concavo-convex groove.
Application number is that the patent specification of CN03216552.8 discloses a kind of " section formula groove filter rod ", groove embossing on the inner wrapping paper is along the axial setting of filter core rod, disconnect between the two axial adjacent grooves embossings and form section, the set of section and groove embossing and shaping paper formation helical duct on the inner wrapping paper.This section helps the circulation of flue gas, does not have the effect of stopping and filtering flue gas, and the filtration of the cigarette filter tip of making weakens to some extent.
The utility model content
The utility model purpose: the cigarette filter tip that overcomes the plain paper of other fibre-bearings is held back the not strong defective of function to flue gas, and a kind of two-chamber section cigarette filter tip of well holding back effect that flue gas is had is provided.
Technical scheme: cigarette filter tip of the present utility model has the filter core and the shaping paper of common cigarette filter tip, in the filter core periphery, shaping paper is inner also has a circle two-chamber cellulose paper.Described two-chamber cellulose paper is formed by five sections, be respectively the first groove section, first cavity segment, the second groove section, second cavity segment, the 3rd groove section in order, the groove section is the cellulose paper section with concavo-convex groove of circular arc, sector or circular arc and knuckle combination shape cross section, and cavity segment is smooth cellulose paper.Every section length is the 1/2-1/20 of cigarette filter tip length.
The external diameter of described three groove sections equates, is 5.0mm-8.0mm, is ramuscule cigarette or common specification cigarette connection use, and three groove sections are obvious to the condensation of flue gas; The external diameter of two cavity segment is all less than the external diameter 0.05mm-1mm of groove section, and flue gas is flowed through these two sections the time, and resistance to suction increases, to the increasing of holding back of flue gas.
Described two cavity segment are preferably external diameter and equate, and are preferred all less than the external diameter 0.1mm of groove section.
The degree of depth of the concavo-convex groove of described three groove sections can be the 1/5-1/20 of cigarette filter tip diameter.
The section that contains projection in the groove of the described first groove section, the second groove section, the 3rd groove section, any two sections groove sections or three sections groove sections, section contains in every groove of this groove section or in the part groove, and the height of section is not more than the degree of depth of groove.The length of described section can be the length 1/2-1/10 of the groove section at section place, and the shape of cross section of section can be the combination shape of polygon, circular arc or polygon and circular arc, and the specification of section can be identical or different with shape.
Beneficial effect: cigarette filter tip novel structure of the present utility model, two cavity segment and section can more effectively be held back harmful substance in the flue gas, are of value to smoker's health; Three groove sections are carried out abundant condensation to flue gas, and smoker's mouthfeel is better.The utility model can provide high-grade cigarette filter tip new varieties and cigarette new varieties for cigarette filter tip manufacturing enterprise, tobacco productive corporation, consumer, enriches market structure.
Description of drawings
Fig. 1 is a perspective view of the two-chamber cellulose paper of the utility model when not wrapping up shaping paper;
Fig. 2 be among Fig. 1 A-A to schematic cross-section;
Fig. 3 be among Fig. 1 B-B to schematic cross-section.
Among the figure: 1, filter core; 2, the first groove section; 3, first cavity segment; 4, the second groove section; 5, second cavity segment; 6, the 3rd groove section; 7, section.
The specific embodiment
Select common cellulose paper for use, on suitable machinery and mould, make the two-chamber cellulose paper shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the two-chamber cellulose paper is formed by five sections, is respectively the first groove section 2, first cavity segment 3, the second groove section 4, second cavity segment 5, the 3rd groove section 6 in order.Wherein, the groove section is the cellulose paper section with concavo-convex groove of sector cross section, and cavity segment is smooth cellulose paper; Every section length is the 1/3-1/9 of cigarette filter tip length.
In accompanying drawing 1, make cigarette filter tip after, the external diameter of two cavity segment equates, all less than the external diameter 0.1mm of groove section.
The degree of depth of the concavo-convex groove of three groove sections be after making the cigarette filter tip diameter 1/10.In the second groove section 4, also contain the section 7 of a projection between one in one the concavo-convex groove, the height of section 7 is less than the degree of depth of groove, and the length of section 7 is the length 1/5 of the second groove section 4, and the shape of cross section of section 7 is fan-shaped.
