Abstract

The utility model relates to a hollow ternary composite cigarette filler tip with low cost and high detaining rate, which is composed of a ternary filter tip wrapping paper and a core body. The core body is divided into three parts, the core body has two cylindrical rods at the two ends and a middle part which is a hollow cavity filled with particle adsorbent. The utility model has the advantages of low cost, good effect of absorption, etc.

Description

Three-dimensional compound filter tip of cigarette

The utility model relates to a kind of improved cigarette filter, the compound cigarette filter of ternary that particularly a kind of low-cost height is held back efficient.

Existing cigarette filter has pure acetate fiber filter tip (see figure 1), pure polypropylene fiber filter tip (see figure 1), two yuan of composite filter tip (see figure 2)s.The cigarette filter of selling on the market mainly is a pure fibrous filter as shown in Figure 1.When this filter tip is hinged with the last suction of cigarette, can filters and hold back tar component harmful in a part of main flume.But, because material is single, this filter tip to the filtration of harmful substances such as the acetaldehyde in the main flume, methacrylaldehyde, hydrocyanic acid, to hold back effect remarkable inadequately.In order to improve cigarette filter, two yuan of composite filter tips have as shown in Figure 2 been developed to volatile matter, the filtration of half volatile matter, adsorption effect in the flue gas.This filter tip is made up of two or more material, promptly is composited by acetate fiber section and the acetate fiber section of having added activated carbon granule.The purer acetate fiber filter tip of this two yuan of composite filter tips has better adsorptivity to gaseous substance.But in use there is the problem of two aspects in this filter tip, and promptly (I) causes cutting the easy passivation of blade of this filter tip; (II) a part of active carbon can come off out in filter tip because of blade cuts, pollutes machine and production environment.

The purpose of this utility model provides a kind of improved low cost, and high rejection can be hinged with the ternary composite filter tip on the cigarette easily.

The utility model is finished as follows: filter tip is made of triple filters obbbin (1), former excellent obbbin (2) and core body, core body is divided into three sections, two ends are two poles, be respectively nearly lip end pole (3), nearly cigarette end pole (4), middle one section is the cavity (5) of filler particles adsorbent.

The employed material of pole can be polypropylene fiber, polypropylene fiber nonwoven, body paper, acetate fiber etc.

The material that granule adsorbent uses can be in active carbon, medical stone, concavo-convex rod, converted starch, silica gel, magnesium silicate, magnesium silicate peppermint, the alumina silicate etc. one or both or two or more.

The utility model has compared with prior art that cost is low, advantages of good adsorption effect, the advantage that easily realizes.

Be further described below in conjunction with accompanying drawing:

Fig. 1 is existing monobasic filter tip;

Fig. 2 is existing dual filter;

The triple filters that Fig. 3 relates to for the utility model.

In the drawings: (1) triple filters obbbin, (2) former excellent obbbin, (3) nearly lip end pole, (4) nearly cigarette end pole, the cavity of (5) filler particles adsorbent.

Pole (3), (4) at the cavity of filler particles adsorbent (5) two ends create earlier on common filter forming machine, on ternary composite filter tip make-up machine, compound pole (3), (4) are cut into the segment of certain-length then, cross arrangement can be filled a certain amount of adsorbents such as active carbon, medical stone, concavo-convex rod, converted starch, silica gel, magnesium silicate, magnesium silicate peppermint, alumina silicate in the cavity (5) of the filler particles adsorbent that stays.Nearly cigarette end pole (4) is used former excellent obbbin (2) parcel in advance, and the nearly lip end pole (3) that will prepare then, nearly cigarette end pole (4) make up the back with the cavity (5) of having filled granule adsorbent and be prepared into the compound cigarette filter of ternary with filter tip obbbin (1) parcel.

Claims

1, the compound cigarette filter of novel tertiary, constitute by triple filters obbbin (1), former excellent obbbin (2) and core body, it is characterized in that core body is divided into three sections, two ends are two poles, be respectively nearly lip end pole (3), nearly cigarette end pole (4), middle one section is the cavity (5) of filler particles adsorbent.

2, the compound cigarette filter of novel tertiary according to claim 1 is characterized by: the employed material of pole can be polypropylene fiber, nonwoven polypropylene fabric, body paper, acetate fiber.
