Countersunk filter tip, cigarette and preparation method

Abstract

The countersunk filter tip comprises a cavity section making contact with the oral cavity and a filter section away from the oral cavity, and the cavity section and the filter section are formed by wrapping forming paper. The invention further discloses a cigarette adopting the countersunk filter tip and a preparation method of the countersunk filter tip. According to the filter tip and the cigarette, on one hand, the use amount of tows is reduced, environmental pollution is reduced, meanwhile, the situation that smoke is hot is effectively reduced through the arrangement of the cavities, the sections and the gaps, the smoking experience is improved, and the positive popularization value is achieved.

Description

Technical field [0001] The present invention relates to a filter, specifically, a deposited head filter and a preparation method thereof, belonging to the technical field of cigarette products. Background technique [0002] Cigarette products include articles that can be burned to generate flue gas or heating but not burning to generate flue gas. Regardless of how the flue gas generates mechanism, cigarettes usually filter out one or more components of the tobacco gas in the tobacco gas by filtering. [0003] Cigarette products are typically wrapped in tobacco sections and filters. Among them, the tobacco segment is typically prepared by a cut filler that is uniformly filled by a forming paper package, and the filter is typically prepared from a shaped paper wrapped wire beam. Smokers are used by igniting one end of the cigarette products and burns the tobacco bar. Smokers accept mainstream flue gas by suction of the filter tip end of the cigarette product. [0004] Typically, th...

Problems solved by technology

[0004] Usually, all filters are filled with tow, and the amount of tow is large, and the tow is usually a material that is difficult to degrade, which has a great impact on the environment

On the other hand, the filter tip is in contact with the oral cavity. When the cigarette product is drawn to the end of the tobacco section, the filter tip tends to become hot and affect the smoking experience.

In the Chinese utility model patent whose publication number is CN211185847U, a kind of cigarette that can change different flavors is introduced. The molding process is relatively complicated and the production efficiency is low.

In the Chinese utility model patent whose publication number is CN 202232975U, a cigarette filter tip is introduced, which uses hard paper laps to bond to form countersunk filter rods. Obvious steps, when the cigarette product is rolled, there will be obvious stratification on the end face of the cigarette, which will affect the appearance of the cigarette and reduce the smoking experience
