Description

Cigarette filter tip with adjustable suction resistance distribution

Technical Field

The invention relates to the technical field of cigarettes, in particular to a cigarette filter tip with adjustable suction resistance distribution.

Background

The filter tip is used as a bridge between a smoker and main stream smoke, not only can filter out part of harmful components in the smoke, but also can effectively intercept total particulate matters in the main stream smoke of the cigarette, reduce tar content and reduce harm of the smoke to human health and environment by connecting the filter tip on the cigarette.

From a sensory point of view, the most obvious effect that filters have on the consumer is a change in the resistance to draw, which is generally greater for longer filters. However, the requirements of consumers on cigarette smoking resistance are not the same, and the cigarettes with low smoking resistance are slightly favored, so that the cigarettes are considered to have better comfort during smoking, but the smoke concentration is increased due to low smoking resistance, so that a plurality of smokers are not suitable. There is therefore a need to develop a class of filters with adjustable smoke concentration to meet the different demands of consumers. Therefore, the invention aims to develop a cigarette filter which can automatically adjust the suction resistance distribution by consumers so as to adjust the smoke concentration.

Disclosure of Invention

The invention aims to provide a cigarette filter with adjustable suction resistance distribution, which can enable a consumer to automatically pass through a extruded tow section to slide, and adjust the positions of the extruded tow section and a vent hole on tipping paper so as to achieve the purpose of adjusting the suction resistance distribution and meet different requirements of the consumer.

The main principle of the invention is as follows: on the basis of the structure of the ternary hollow filter tip, no adhesive is coated between the forming paper and the tipping paper of the tow segments, so that the two tow segments can freely slide in position through extrusion; the air vent is arranged on the tipping paper of the middle hollow section, and the positions of the two sections of filament bundle sections and the air vent are adjusted by sliding the two sections of filament bundle sections, so that the purpose of adjusting the suction resistance distribution is achieved, and different requirements of consumers are met. The concrete structure is as follows:

the cigarette filter with adjustable suction resistance distribution is of a ternary cavity filter structure, namely a front section and a rear section are tow sections, two sections of tow are respectively wrapped with forming paper to form tow sections (common filter sticks), the middle of the two sections of tow sections is set at a certain distance, and then the two sections of tow sections are wrapped with tipping paper to form a filter stick, so that the middle section of the filter stick is the cavity section, and the tipping paper of the cavity section is provided with ventilation holes.

The tows of the tow segments are common acetate fibers, or polypropylene fibers, or other cut tobaccos, papers and the like with certain suction resistance; the forming paper adopts forming paper with high air permeability.

The tipping paper is arranged at the middle position of the ventilation hole of the cavity section and is perforated on the whole circumference, so that the movable range of the front and rear tow sections is enlarged, and the adjustability is improved. The ventilation degree of the arranged ventilation holes can be adjusted according to the requirement, wherein the ventilation degree value is the percentage of the total air flow of the air entering the ventilation holes from the outside.

The tipping paper material needs to have a certain hardness to increase the non-deformability of the filter, and hard paper, flexible plastic and the like are adopted.

Other processes and materials involved in producing the cigarette filter of the invention and existing methods for producing the filter for passing cigarettes are adopted.

When in use, the filament bundle section can freely slide to a required position by extruding the filament bundle section according to the needs of a smoker; the air vent is arranged on the tipping paper of the middle hollow section, and the positions of the two sections of filament bundle sections and the air vent are adjusted by sliding the two sections of filament bundle sections, so that the purpose of adjusting the suction resistance distribution is achieved, and finally the effect of adjusting the smoke concentration is achieved. When the filament bundle section at the upstream end of the vent hole is longer, the overall suction resistance is smaller; the longer the downstream end strand segment, the greater the overall suction resistance.

The cigarette filter tip with adjustable suction resistance distribution can enable consumers to automatically pass through the extruded tow segments to slide, and the positions of the extruded tow segments and the vent holes on tipping paper are adjusted, so that the purpose of adjusting the suction resistance distribution is achieved, and different requirements of the consumers are met. Meanwhile, due to the unique structure, the playability of the cigarettes can be improved, and the differentiation of products is improved. The invention does not need to additionally develop equipment, is easy to form, and is convenient and quick.
