Abstract

A high permeating groove filter tip candle comprises a groove construction designed on a filter tip candle forming paper with a permeating degree of 800CU-20000CU. The groove is designed to partially spread on the filter tip and axially arrange from the exposed suction, or intermittently spread to another end of the filter tip. The function of utility model is that the filter tip candle forming paper promotes the permeating degree properly and cooperates with the groove structure thereby improving the sucking quality and safety of the cigarette as reducing injury and tar but improving profit.

Description

High ventilative groove filter rod

Affiliated technical field: the utility model relates to the manufacturing of cigarette filter stick.

Background technology: the air permeability (CU) of the filter-tip tow filter core of existing plough groove type internal layer forming paper, normally below 1000CU.Though filter tip internal layer forming paper has also adopted groove structure,, still there be the shortcoming of filter efficiency than low and filter effect aspect because air permeability is lower.

Content of the present invention: the purpose of this utility model, provide a kind ofly than high-air-permeability, and improve the ventilative groove filter rod of height of filter efficiency and filter effect.

The technical scheme that its technical problem that solves the utility model adopts is: the filter tow filter core is coating and is making fluted filter rod high porosity plug wrap paper, it is characterized in that: make the air permeability that fluted filter rod high porosity plug wrap paper has 800CU～20000CU.Groove makes and exposes initially from the filter tip aspiration port on the filter rod high porosity plug wrap paper, and axially-aligned ground distributes local extension of filter tip, or extends to the other end of filter tip intermittently.

The beneficial effects of the utility model are: and the high-air-permeability of described filter rod internal layer forming paper (800CU～20000CU) in conjunction with groove structure, it is air permeability with suitable raising internal layer forming paper, and in conjunction with the change of the formed tow filter core of groove pressure drop and the state at different pressures position, make ventilative, pressure drop, the resistance to suction of filter tip produce useful change, improve the filter efficiency and the effect of filter tip, and produce the raising of smoking property of cigarette quality and security thus, reach the purpose of " harm reduction, fall Jiao, gain ".
