Abstract

The utility model provides a ternary composite filter tip with a CAPF coaxial filter segment and cellulose acetate fiber filter segments. A segment A, a segment B and a segment C are connected together in sequence and coated by outer ring forming paper or tipping paper to form the filter tip. The segments A and C are both cellulose acetate fiber filter segments; the segment B is a CAPF coaxial filter segment; and when the composite filter tip is connected to a tobacco stem, the segment A is at the end close to the lip, the segment B is in the middle, and the segment C is the end close to tobacco shred. The filter tip disclosed by the utility model has lower manufacturing cost than other types of ternary composite filter tips and is suitable for being matched with middle and high-end tobacco products in use.

Description

The ternary composite filter tip that contains the coaxial filter section of CAPF and acetate fiber filter section

Technical field

The utility model relates to polynary composite smoke and splices composite filter tip with the ternary in filter tip.

Background technology

Common filter for cigarette is single hop (constituent element) structure, and it filters, the performance of absorption flue gas is limited, and the special suction sensations such as fragrance can not be provided.Now adopt some new technology in industry, come the cigarette filter tip of production binary or multi-factor structure.Owing to lacking unified standard, constituent element is complicated, is difficult to check and judges its performance and applicable cigarette grade.

Number of patent application is 201120292080.4 " polynary composite filter tip and multi-element composite filter stick ", has multiple filter core section, and peripheral same forming paper forms.Wherein a kind of filter core section is the paper filter element section that contains the vinegar fibre, and all the other filter core sections are the fine filter core section of vinegar, the third fine filter core section, paper filter element section, contain two or more in acticarbon filter core section, colored filter core section.Perhaps, a kind of filter core section, two kinds of filter core sections or several filter core sections also have respectively coaxial inner core separately, and the diameter of coaxial inner core is the 1/5-4/5 of filter tip diameter.The cellulose paper that one circle channel form also can be arranged between forming paper and filter core.This filter stick and the filter tip constituent element of making thereof are complicated, are difficult to control its absorption property of metering.

Summary of the invention

Utility model purpose: overcome that traditional polynary composite filter tip constituent element is complicated, filter effect is difficult to the defective accurately controlled, the ternary composite filter tip that contains the coaxial filter section of CAPF and acetate fiber filter section that provide a kind of resistance to suction of three sections constituent elements different, filter effect can regulate and control, production cost is lower.

Technical scheme:

The utility model provides the ternary composite filter tip of the coaxial filter section of a kind of CAPF of containing and acetate fiber filter section, be connected in turn by these three sections of A sections, B section, C section, formed by same outer ring forming paper or cork paper parcel, A section and C section are acetate fiber filter section, and the B section is the coaxial filter section of CAPF; Three sections length variations scopes separately are 5mm-30mm.When this composite filter tip was connected on the cigarette rod, the A section was nearly lip end (during the cigarette suction, being contained in an end of lip), and the B section is in the centre, and the C section is at nearly pipe tobacco end (end that filter tip is connected with the cigarette rod).

Acetate fiber filter section is that the filter core or the filter stick that are prepared from take acetate fiber as main filter material (also claim common vinegar fine white rod, the filter core that is enclosed with forming paper is called filter stick), or be acetate fiber groove filter core or filter stick (acetate fiber filter core periphery have a circle groove fiber element paper, groove fiber element paper is the cellulose paper that paper has continuous or discrete groove); Preferred A section and C section are acetate fiber groove filter core or filter stick.

The coaxial filter section of CAPF is coaxial filter core or the filter stick that is composited by CAPF paper filter element and other filter core, (CAPF paper wherein refer to contain the chopped acetate fiber of 5%-50% and the paper of wood pulp cellulose), the B section is preferably the CAPF paper filter element as coaxial inner core, and the acetate fiber filter core is as coaxial outer core; The cross-sectional area of the inner core of preferred CAPF paper is the 1/3-2/3 of the cross-sectional area of this composite filter tip.

Three segment length can identical or successively decrease (A segment length≤B segment length≤C segment length); Preferred three segment length are identical, are 5mm-10mm; Or three segment length be followed successively by: A segment length 5mm, B segment length 10mm, C segment length 15mm.

Under the prerequisite of a constant pressure drop, should as much as possible improve the pressure drop of B section, C section, reduce the pressure drop of A section, promote the filter capacity of B section, C section; Namely by the A section to B section, C section, resistance to suction increases successively, is conducive to the tar interception that discharges after cigarette rod burning innerly at filter tip, is sucked by mouth less.

Beneficial effect: though the filter tip manufacturing cost of this programme higher than common filter tip, lower than the ternary composite filter tip of other type, is applicable to supporting the use of middle and high end cigarette product.

In figure: 1, nearly lip end; 2, A section; 3, groove fiber element paper; 4, B section; 5, C section; 6, nearly pipe tobacco end; 7, cigarette rod; 8, outer ring forming paper or cork paper; 9, forming paper.

The specific embodiment

Embodiment:

The ternary composite filter tip that contains the coaxial filter section of CAPF and acetate fiber filter section as shown in Figure 1, by the long C section of the long A section 2 of 5mm, the long B section 4 of 10mm, 15mm 5 these three sections be connected in turn, formed by same outer ring forming paper or cork paper 8 parcels, described A section 2 and C section 5 are acetate fiber filter section, and B section 4 is the coaxial filter section of CAPF; When this composite filter tip was connected on cigarette rod 7, A section 2 was at nearly lip end 1, and B section 4 is in the centre, and C section 5 is at nearly pipe tobacco end 6.

Described A section 2 is acetate fiber groove filter core, and C section 5 is for having the acetate fiber furrowfilter rod of groove fiber element paper 3.Described B section 4 be the CAPF paper filter element as coaxial inner core, the acetate fiber filter core is as coaxial outer core; The cross-sectional area of inner core be this composite filter tip cross-sectional area 1/2.
