Description
공기가 통하는 필터 담배는 동축 필터 코어(coaxial filter core)와 동축 필터 코어를 둘러싼 필터 케이싱(casing)을 포함한 필터 섹션(section)을 가지고 있는 EP 0 875 160 A1에 기술된다. 이 동축 필터 섹션((coaxial filter section) 영역에서 통풍 구멍들은 케이싱에 통풍 공기의 유입을 제공된다. 재료 특성의 구성과 담뱃잎 스트랜드 및 필터 각각의 요소의 치수는 만약 흡연자가 통풍 구멍을 덮어버린다면, 전환밸브의 형식에 의해서 연기는 반드시 필터 케이싱(casing)으로 이끌려지도록 디자인된다. 반면에 통풍 구멍을 덮어 버리지 않는다면, 연기는 주로 동축 필터 섹션의 필터 코어를 통해서 흐르도록 디자인된다. 이러한 개발의 목적은 예를 들어 증가되는 응축물의 값을 최소화하는 것과 같은, 다양한 소비자의 행동에 따른 연기 생산을 양적으로 제어하는 데 있다.Airborne filter cigarettes are described in EP 0 875 160 A1, which has a filter section including a coaxial filter core and a filter casing surrounding the coaxial filter core. The ventilation holes in the coaxial filter section area provide for the introduction of ventilation air into the casing. The composition of the material characteristics and the dimensions of the respective elements of the tobacco strand and filter, if the smoker covers the ventilation holes, Depending on the type of valve, the smoke is designed to be drawn into the filter casing, while the smoke is designed to flow primarily through the filter core of the coaxial filter section, unless the vent hole is covered. To quantitatively control smoke production according to various consumer behaviors, such as minimizing the value of the condensate being increased.
물리적인 관점에서 이 연기는 공기와 액체방울(liquid droplets)의 혼합물인에어졸(aerosol)이다. 이것들은 분명히 다양한 크기를 가지고 있을 수 있고, 어떤 것들은 인간의 눈으로 볼 수 없는 것도 있다.From a physical point of view, this smoke is aerosol, a mixture of air and liquid droplets. These can obviously be of various sizes, some of which are not visible to the human eye.
소비자에 의한 담배 연기의 맛의 평가 즉, 향기의 질 또는 맛의 느낌의 감도는 연기 흐름의 속도에 의해서, 작은 물방울(droplets)의 크기와 휴대성 분석기의 도움을 받아 측정한 그것들의 분포에 의해서, 또는 입자의 무게나 입자의 크기에 의해 선택적으로 모으고 정렬되는 것에 의해서 영향을 받는다.The evaluation of the taste of tobacco smoke by the consumer, that is, the sensitivity of the quality of the flavor or the taste sensation, depends on the speed of the smoke flow, the size of the droplets and their distribution measured with the aid of the portability analyzer , Or by selectively collecting and aligning by the weight of the particles or the size of the particles.
본 발명은 청구항1의 전제부에 따른 공기가 통하는 필터 담배에 관한 것이다.The present invention relates to an air-permeable filter cigarette according to the preamble of claim 1.
도 1은 본 발명에 의한 필터담배의 개략도.1 is a schematic view of a filter cigarette according to the present invention.
본 발명의 목적은 흡연자에게 공급되어지는 작은 물방울 크기의 분포와 연기의 흐름률을 제어될 수 있는 필터디자인을 창작하는데 있다.It is an object of the present invention to create a filter design that can control the distribution of small droplet sizes supplied to smokers and the rate of smoke flow.
이러한 목적은 청구항 1의 특징을 가지는 필터 담배에 의해 달성된다.This object is achieved by a filter cigarette having the features of claim 1.
만약 입측 필터 섹션(mouth-side filer section)에서 코어의 표면은 공기-불침투식으로 포장을 되거나 공기-불침투식으로 제조된다면, 주 연기의 측면의 흐름은 피해질 수 있다.If the surface of the core in the mouth-side filer section is fabricated by air-infiltration or by air-infiltration, the flow of the side of the mainstream smoke may be avoided.
맛에 있어서 주요한 향상은 종래 기술의 상태와 비교하여 그것들에 의해 달성된다.Major improvements in taste are achieved by them compared to the state of the art.
본 발명은 하기의 몇 단계를 수행하는 필터디자인을 통해 달성된다.The present invention is achieved through a filter design which performs the following several steps.
첫 번째 단계에서, 응축물과 니코틴값은 담뱃잎 스트랜드에 면하는 필터 섹션에 매우 짧은 섹션에 설정된다. 두 번째 단계에서는, 주 연기에 의해 사용되어진 이 부근에서 대략 3배정도로 연기를 가속하는 필터 지름의 감소에 있다. 응축물의값을 감소시키는 것과 함께 그러한 필터디자인은 종래의 필터와 비교하여 향기에 있어서 명백한 증가를 이끌게 된다. 그것은 연기 성분과 평균적인 물방울 크기 둘다 흐름률의 변화에 의해 영향을 받는다는 것을 보여주고, 향기의 느낌 그리고 앞서 말한 맛은 이를테면 명백히 더 높은 관통 흐름률을 증가시킨다는 것을 보여준다.In the first step, the condensate and nicotine values are set in very short sections in the filter section facing the tobacco strand. In the second stage, there is a reduction in the filter diameter which accelerates the smoke by about three times in the vicinity of that used by the main fume. Such a filter design, along with reducing the value of the condensate, leads to an obvious increase in aroma compared to conventional filters. It shows that both the smoke content and the average droplet size are influenced by changes in the flow rate, and the feeling of aroma and the above-mentioned taste obviously increases the higher through flow rate.
흡입 저항(drawing resistance) 및 유지(retention)가 본 발명에 있어서 담배로부터 분리됨에 따라 흡연자를 매우 즐겁게 해주는 흡입(drawing) 품질 또한 얻을 수 있다.As drawing resistance and retention are separated from the cigarettes in the present invention, a drawing quality which makes the smoker very enjoyable can also be obtained.
본 발명은 이하 개략도를 이용하여 세부적으로 설명된다.The present invention will now be described in detail with reference to the accompanying schematic drawings.

다른 버전의 범위가 하기와 같이 고려될 수 있다.Other versions of the range may be considered as follows.
코어에서는, 3.0에서 8.0den사이의 범위의 단일 적정층은, 바람직하게는 6.0den이고 15,000에서 50,000den사이의 범위의 총 적정층은, 바람직하게는 17,000den이다. 케이싱(2)에서는 1.5에서 3.0den의 범위의 단일 적정층은 바람직하게는 2.1den이고, 40,000에서 75,000den사이의 범위의 총 적정층은, 바람직하게는 55,000den이다.In the core, the single titration layer in the range between 3.0 and 8.0 den is preferably 6.0 den and the total titratable bed in the range between 15,000 and 50,000 den is preferably 17,000 den. In the casing (2), the single optimum layer in the range of 1.5 to 3.0 den is preferably 2.1 den, and the total modulus in the range of 40,000 to 75,000 den is preferably 55,000 den.
담뱃잎 스트랜드측 단일 적정 농도의 범위는 1.5에서 5den사이이며, 총 적정 농도는 15,000에서 60,000den사이이다.The range of the single optimum concentration of the tobacco strand side is between 1.5 and 5 den, and the total optimum concentration is between 15,000 and 60,000 den.
위의 예는 스트랜드측 필터 섹션에서 흐름률과 비교하여 코어에서 흐름률에 대략 3배 증가된다는 것을 보여준다.The above example shows that the flow rate in the core is increased about three times compared to the flow rate in the strand side filter section.
본 발명은 흡연자에게 공급되어지는 작은 물방울 크기의 분포와 연기의 흐름률을 제어될 수 있는 필터디자인을 제공할 수 있다.The present invention can provide a filter design capable of controlling the distribution of small droplet sizes supplied to smokers and the flow rate of smoke.
