Problems solved by technology

[0005] The problem with the latter filter materials is that they have a higher filtration efficiency than cellulose acetate for particulate matter ("tar") in mainstream smoke
The filter material limits the level of PMWNF as there are maximum restrictions on the production of carbon monoxide and the production of PMWNF in many countries and the regulations of the European Union (EU)

Embodiment Construction

[0030] figure 1 Embodiments of smoking articles are shown schematically. The smoking product is a cigarette 1 , and the cigarette 1 includes a smokable tobacco rod 2 (tobacco wrapped in cigarette paper) and a double filter 3 . Double filter 3 using tipping paper ( figure 1 (not shown in ) is attached to the smokeable tobacco rod 2. The double filter 3 has a first end 4 adjoining the tobacco rod 2 and a second end 5 which is the mouth-side filter end.

[0031] The double filter 3 comprises a first filter section 11 on the tobacco rod side and a second filter section 12 on the mouthpiece side. The first filter section 11 comprises chopped or shredded vegetable material (in the embodiment tobacco), while the second filter section 12 comprises cellulosic material (in the embodiment paper) as filter material. Each filter section 11, 12 includes a plug wrap, and both filter sections 11, 12 utilize an additional wrapper (plug wrap) figure 1 not shown) are engaged.

Abstract

A smoking article (1) comprises a smokable tobacco rod (2), which includes tobacco and a wrapper, and a filter (3) having a first end (4) and a second end (5). The filter (3) comprises a first filter segment (11) extending to the first end (4) of the filter (3) and placed at an end of the tobacco rod (2) and a second filter segment (12) extending to the second end (5) of the filter (3). The first filter segment (11) comprises cut or shredded plant material. The second filter segment (12) comprises a cellulose material as filtering material and has a length in the range of from 3 mm to 12 mm. The filter (3) is bio-degradable according to OECD 301 B.

Description

technical field [0001] The present invention relates to a smoking article with a biodegradable filter tip. Background technique [0002] Smoking articles (eg, cigarettes) typically include a smokeable tobacco rod wrapped in a wrapper (eg, cigarette paper) and a filter attached to the tobacco rod with tipping paper. The perforations in the layer surrounding the filter material allow air flow through the filter and thereby dilute mainstream smoke with air. [0003] Filters for smoking articles are generally constructed of two or more axially aligned segments to achieve specific filter characteristics. Depending on the number of filter segments, double filters, triple filters etc. are known. [0004] Cellulose acetate is the most commonly used filter material for smoking articles. However, cellulose acetate has poor biodegradability in composting environments or in standardized tests like OECD 301 B. Filter materials with improved biodegradability are also known, for exampl...
