Description

흡연물품용 필터 및 이를 포함하는 흡연물품Filters for smoking articles and smoking articles containing the same
본 발명은 흡연물품용 필터 및 이를 포함하는 흡연물품에 관한 것이다.The present invention relates to a filter for smoking articles and a smoking article containing the same.
일반적으로 담배는 쌍떡잎 식물목 가지과의 여러해살이풀을 말하지만, 최근에는 담배의 잎을 궐련지로 싸고 일측에 필터부가 구성되어 흡연을 목적으로 제조된 제품을 통칭하기도 한다. 이러한 담배는 전세계적으로 수천 종에 이르며, 다양한 모양이나 형태로 출시되고 있다.In general, tobacco refers to a perennial plant of the dicotyledonous plant family Solanaceae, but recently, it is also commonly referred to as a product manufactured for smoking purposes by wrapping tobacco leaves in cigarette paper and forming a filter section on one side. There are thousands of types of such cigarettes worldwide, and they are released in various shapes and forms.
담배의 근위단부(Mouth end, ME)에는 필터가 위치하여, 담배연기의 입자와 증기상을 제거함으로써 연기성분을 여과하는 역할을 한다.A filter is located at the proximal end (ME) of the cigarette and serves to filter smoke components by removing particles and vapor phase of the cigarette smoke.
그러나, 필터를 감싸고 있는 필터권지는 종이이므로, 흡연 중 담배 연기가 필터를 통과하여 흡연자의 손가락이 직접 닿는 부분에 담배 냄새가 배고, 흡연 시 필터 단면에 얼룩이 생기는 문제점이 있다.However, since the filter paper surrounding the filter is paper, there is a problem that cigarette smoke passes through the filter during smoking, causing the cigarette smell to permeate the area where the smoker's fingers directly contact, and staining the cross-section of the filter when smoking.
이에, 상기와 같은 기존 기술의 문제점 및/또는 한계점을 극복하기 위하여, 본 발명은, 2 이상의 필터부를 포함하고, 2 이상의 필터부 중 적어도 하나의 필터부에 2 내지 4 개의 홀을 포함하는 흡연물품용 필터, 및 이를 포함하는 흡연물품을 제공하는 것을 목적으로 한다.Accordingly, in order to overcome the problems and/or limitations of the existing technology as described above, the present invention provides a smoking article comprising two or more filter parts and 2 to 4 holes in at least one filter part of the two or more filter parts. The purpose is to provide a filter for use, and a smoking article containing the same.
그러나 본 발명이 해결하고자 하는 과제는 이상에서 언급한 과제로 제한되지 않으며, 언급되지 않은 또 다른 과제들은 아래의 기재로부터 해당 기술분야의 통상의 지식을 가진 자에게 명확하게 이해될 수 있을 것이다.However, the problem to be solved by the present invention is not limited to the problems mentioned above, and other problems not mentioned can be clearly understood by those skilled in the art from the description below.
본 발명의 일 실시예에 따르면, 2 이상의 필터부를 포함하고, 2 이상의 필터부 중 적어도 하나의 필터부에 2 내지 4 개의 홀을 포함하는, 흡연물품용 필터를 제공한다.According to one embodiment of the present invention, a filter for a smoking article is provided, including two or more filter parts, and at least one filter part of the two or more filter parts including 2 to 4 holes.
일 측에 따르면, 상기 흡연물품용 필터를 포함하는, 흡연물품을 제공한다.According to one side, a smoking article including a filter for the smoking article is provided.
본 발명을 이용하면, 종래의 일반 튜브필터보다 더 높은 흡인저항을 제공하고, 연기 중의 연기성분 제거율을 높일 수 있다. 뿐만 아니라, 주류연과 천공부위를 통해 유입되는 공기를 다중홀로 유도하여 흡연 시 담배 냄새가 손에 배는 것을 줄일 수 있다. 또한, 흡연 시 필터 단면에 생기는 얼룩을 감소시켜 흡연 후에도 필터 단면이 깨끗하게 보임으로써 흡연자에게 만족감을 줄 수 있다.Using the present invention, it is possible to provide higher suction resistance than conventional general tube filters and increase the removal rate of smoke components in smoke. In addition, by directing the mainstream smoke and the air flowing in through the perforated area into multiple holes, it is possible to reduce the smell of cigarettes from permeating your hands when smoking. In addition, it reduces stains that appear on the filter cross-section when smoking, making the filter cross-section look clean even after smoking, giving smokers a sense of satisfaction.

이하에서는, 도면을 참조하여 본 발명의 실시예들을 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
도 1 을 참고하면, 흡연물품(100)은 일 예로 필터(10)와 담배 매질부(20)를 포함한다. 담배 매질부를 연소하면 담배 연기가 생성되고, 생성된 담배 연기는 필터를 통과하여 흡연자의 폐로 들어간다. Referring to FIG. 1 , the smoking article 100 includes a filter 10 and a tobacco media unit 20 as an example. When the tobacco medium is burned, cigarette smoke is generated, and the generated cigarette smoke passes through the filter and enters the smoker's lungs.
본 발명의 일 실시예에 따르면, 2 이상의 필터부를 포함할 수 있고, 구체적으로, 2 내지 4 의 필터부, 또는 2 내지 3 의 필터부를 포함할 수 있다. 또한, 상기 2 이상의 필터부 중 적어도 하나의 필터부에 2 내지 4 개의 홀, 바람직하게는 3 개의 홀을 포함하는, 흡연물품용 필터를 제공한다.According to one embodiment of the present invention, it may include two or more filter units, and specifically, it may include 2 to 4 filter units, or 2 to 3 filter units. In addition, a filter for a smoking article is provided, wherein at least one filter part of the two or more filter parts includes 2 to 4 holes, preferably 3 holes.
일 예로, 도 2 와 같이 필터(10)는 제 1 필터부(11) 및 제 2 필터부(13)를 포함할 수 있다. 제 1 필터부(11)와 제 2 필터부(13)는 각각 근위단부, 원위단부(Tobacco End; TE) 쪽에 위치할 수 있다. 제 1 필터부(11)는 다중홀을 포함할 수 있다. 도 4 은 이러한 필터의 제작 이미지이다. For example, as shown in FIG. 2 , the filter 10 may include a first filter unit 11 and a second filter unit 13. The first filter unit 11 and the second filter unit 13 may be located at the proximal end and the distal end (Tobacco End (TE)), respectively. The first filter unit 11 may include multiple holes. Figure 4 is an image of the production of such a filter.
구체적으로, 상기 필터의 총 길이(15)는 25 내지 30 mm, 바람직하게는 27 mm 일 수 있다. 제 1 필터부(11)의 총 길이는 5 내지 12 mm 일 수 있고, 바람직하게는 9 mm 일 수 있다. 제 2 필터부(13)의 총 길이는 15 내지 22 mm 일 수 있고, 바람직하게는 18 mm 일 수 있다. Specifically, the total length 15 of the filter may be 25 to 30 mm, preferably 27 mm. The total length of the first filter unit 11 may be 5 to 12 mm, and preferably 9 mm. The total length of the second filter unit 13 may be 15 to 22 mm, and preferably 18 mm.
도 3 을 참고하면, 본 발명의 일 실시예에 따른 흡연물품용 필터에 있어서, 다중홀을 포함하는 필터부(11) 단면의 홀 직경(17)은 1 mm 이상 2 mm 이하, 바람직하게는 1.6 mm 이상 1.7 mm 이하일 수 있다.Referring to FIG. 3, in the filter for smoking articles according to an embodiment of the present invention, the hole diameter 17 of the cross section of the filter part 11 including multiple holes is 1 mm or more and 2 mm or less, preferably 1.6 mm. It may be more than mm and less than or equal to 1.7 mm.
홀 직경이 1 mm 미만인 경우, 필터 제조 시 문제점이 발생한다. 구체적으로, 필터 제조 시 고온 및 고압 조건에서 봉을 집어넣어 필터에 홀을 생성한다. 이 때, 봉의 두께가 1 mm 미만으로 가늘어지면 필터 성형 시에 직경이 균일한 홀을 생성하기 어렵다.If the hole diameter is less than 1 mm, problems arise when manufacturing the filter. Specifically, when manufacturing a filter, a rod is inserted under high temperature and pressure conditions to create a hole in the filter. At this time, if the thickness of the rod becomes thinner than 1 mm, it is difficult to create holes of uniform diameter during filter molding.
본 발명의 일 실시예에 따른 흡연물품용 필터에 있어서, 홀들은 필터의 외벽 두께(19)가 0.7 mm 이상 1.3 mm이하, 바람직하게는 1.05 mm 이상 1.15 mm 이하일 수 있으며, 상기 외벽 두께는 필터의 외벽으로부터 홀까지의 최단거리를 기준으로 한다. 또한 홀의 바람직한 크기를 고려하였을 때 (ex. 1.0 mm), 바람직하게는 홀들의 중앙이 필터의 외벽으로부터 1.5 mm 이상이 되는 위치 내에 형성될 수 있다.In the filter for smoking articles according to an embodiment of the present invention, the outer wall thickness 19 of the filter may be 0.7 mm or more and 1.3 mm or less, preferably 1.05 mm or more and 1.15 mm or less, and the outer wall thickness is the thickness of the filter. It is based on the shortest distance from the outer wall to the hall. Also, considering the desirable size of the hole (ex. 1.0 mm), the centers of the holes may be formed at a distance of 1.5 mm or more from the outer wall of the filter.
이는, 궐련 제조 시에 제조된 필터를 절단해야 하는데, 필터의 외벽 두께(19)가 얇으면 벽이 깨지는 문제점이 발생할 수 있기 때문이다.This is because the manufactured filter must be cut when manufacturing a cigarette, and if the outer wall thickness 19 of the filter is thin, the wall may break.
한편, 상기 제 2 필터부(13)는 셀룰로오스 아세테이트, 탄소 또는 종이 중 적어도 하나 또는 이들의 조합을 포함하는 필터일 수 있다. 바람직하게는, 제1필터부가 다중홀을 포함하는 경우, 셀룰로오스 필터 또는 고분자 성형 필터일 수 있다. 다만, 이에 제한되지는 않는다. Meanwhile, the second filter unit 13 may be a filter containing at least one of cellulose acetate, carbon, or paper, or a combination thereof. Preferably, when the first filter unit includes multiple holes, it may be a cellulose filter or a polymer molded filter. However, it is not limited to this.
필터는 필터권지에 의해 둘러싸여 있다. 팁페이퍼는 궐련과 필터를 이어주는 종이이고, 천공이 형성되어 있다. 천공은 담배 희석률을 높여 제품의 연기성분을 희석하는 역할을 수행한다. 천공은 근위단부로부터 10.5 내지 11 mm 위치에 형성될 수 있다. 이에 따라, 제 2 필터부(13)에 천공이 위치할 수 있고, 제 2 필터부(13)의 필터권지는 다공성일 수 있다.The filter is surrounded by filter paper. Tip paper is the paper that connects the cigarette and the filter, and has perforations. Perforation plays the role of diluting the smoke component of the product by increasing the dilution rate of the cigarette. The perforation may be formed 10.5 to 11 mm from the proximal end. Accordingly, perforations may be located in the second filter unit 13, and the filter wrapper of the second filter unit 13 may be porous.
본 발명의 일 실시예에 따른 흡연물품용 필터(10)의 둘레는 15 mm 이상 25 mm 이하, 바람직하게는 16.7 mm 이상 24.2 mm 이하일 수 있다. 예를 들어, 필터의 둘레는 레귤러형 담배의 경우 24.2 mm, 슬림형 담배의 경우 21.7 mm, 초슬림형 담배의 경우 16.7 mm 일 수 있다. The circumference of the filter 10 for smoking articles according to an embodiment of the present invention may be 15 mm or more and 25 mm or less, preferably 16.7 mm or more and 24.2 mm or less. For example, the circumference of the filter may be 24.2 mm for a regular cigarette, 21.7 mm for a slim cigarette, and 16.7 mm for an ultra-slim cigarette.
본 발명의 일 실시예에 따른 흡연물품용 필터(10)는 흡인저항이 50 mmH2O/Tip 이상 150 mmH2O/Tip 이하일 수 있다. 흡인저항이 50 mmH2O/Tip보다 작은 경우 필터링의 효과가 지나치게 떨어질 수 있으며, 150 mmH2O/Tip보다 큰 경우 빨림성이 작아져서 사용자가 에어로졸을 흡입하기 어려울 수 있다.The filter 10 for smoking articles according to an embodiment of the present invention may have a suction resistance of 50 mmH 2 O/Tip or more and 150 mmH 2 O/Tip or less. If the suction resistance is less than 50 mmH 2 O/Tip, the filtering effect may be excessively reduced, and if it is greater than 150 mmH 2 O/Tip, the suction resistance may be reduced, making it difficult for the user to inhale the aerosol.
상기 필터에는 향미제가 포함될 수 있다. 향미제로는 민트, 초콜렛, 코코아, 커피, 감초, 고수, 바닐린, 에틸 바닐린, 말톨, 에틸 말톨, 유칼립톨, 초산(Acetic acid), 호흡 프레쉬너(breath freshener) 향, 베르가모트 오일, 로즈마리, 제라늄 오일, 레몬 오일, 오렌지 오일, 라임 오일, 자몽 오일, 민트 오일, 생강 오일, 이소감미제(isosweet) 및 과일향 성분으로 이루어진 군으로부터 선택된 하나 이상일 수 있으며, 상기 나열된 종류에 한정되는 것은 아니다.The filter may contain flavoring agents. Flavoring agents include mint, chocolate, cocoa, coffee, licorice, coriander, vanillin, ethyl vanillin, maltol, ethyl maltol, eucalyptol, acetic acid, breath freshener scent, bergamot oil, rosemary, and geranium oil. , lemon oil, orange oil, lime oil, grapefruit oil, mint oil, ginger oil, isosweetener, and fruit flavor ingredients, and is not limited to the types listed above.
한편, 본 발명의 일 실시예에 따른 흡연물품(100)은 상기 필터(10)를 포함할 수 있다. 생성된 담배 연기는 필터를 거쳐 연기성분이 여과되며, 통상 원위단부 쪽에 위치한 필터부의 연기성분 제거능이 높다.Meanwhile, the smoking article 100 according to an embodiment of the present invention may include the filter 10. The generated cigarette smoke passes through a filter to filter out the smoke components, and the filter portion located at the distal end usually has a high ability to remove smoke components.
상기 흡연물품(100)은 연소식 궐련 또는 가열식(비연소식) 궐련일 수 있으나, 이에 제한되는 것은 아니다.The smoking article 100 may be a combustible cigarette or a heated (non-combustible) cigarette, but is not limited thereto.
상기 흡연물품은 담배 매질부 및 래퍼를 포함할 수 있다. The smoking article may include a tobacco medium and a wrapper.
상기 담배 매질부는 통상적으로 잎담배와 같이 니코틴을 포함하는 담배 물질을 포함하며, 바인더나 기타 첨가제, 상기 언급한 향미제 등과 같은 부형제를 추가적으로 포함할 수 있고, 일 예로서, 본 발명의 담배 매질부에 포함되는 담배 매질은 담배 물질 및 부형제 등을 포함하는 과립의 형태로 제조될 수 있다.The tobacco medium unit typically contains a tobacco material containing nicotine, such as leaf tobacco, and may additionally include excipients such as binders, other additives, and the above-mentioned flavoring agents. As an example, the tobacco medium unit of the present invention The tobacco medium included may be manufactured in the form of granules containing tobacco material and excipients, etc.
담배 잎은 황색종, 버어리종, 오리엔트 종, 시가엽 및 토스트 중 선택된 적어도 하나 이상일 수 있으나, 이에 제한되는 것은 아니다.The tobacco leaves may be at least one selected from yellow leaves, burley leaves, orient leaves, cigar leaves, and toast, but are not limited thereto.
이하, 실시예를 들어 본 발명에 대해 더욱 상세하게 설명할 것이나, 본 발명이 하기 실시예에 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail through examples, but the present invention is not limited to the following examples.

실시예 1Example 1
제 1 필터부와 제 2 필터부를 포함하는 흡연물품용 필터를 제조하였다. 제 1 필터부의 길이는 15 mm이고, 3개의 홀이 형성되어 있으며, 아세테이트 토우를 포함한다. 제 2 필터부의 길이는 12 mm이고, 탄소를 포함한다.A filter for a smoking article including a first filter portion and a second filter portion was manufactured. The length of the first filter part is 15 mm, three holes are formed, and it includes acetate tow. The length of the second filter part is 12 mm and contains carbon.

비교예 1Comparative Example 1
제 1 필터부에 홀이 형성되어 있지 않은 점을 제외하고는, 실시예 1 과 동일한 방법으로 흡연물품용 필터를 제조하였다.A filter for smoking articles was manufactured in the same manner as Example 1, except that no hole was formed in the first filter portion.
비교예 2Comparative Example 2
제 1 필터부에 1개의 홀이 형성되어 있는 것을 제외하고는, 실시예 1 과 동일한 방법으로 흡연물품용 필터를 제조하였다.A filter for smoking articles was manufactured in the same manner as Example 1, except that one hole was formed in the first filter portion.
비교예 3Comparative Example 3
제 1 필터부에 1개의 홀이 형성되어 있고 그 길이가 9 mm이며, 제 2 필터부의 길이가 18 mm인 것을 제외하고는, 실시예 1 과 동일한 방법으로 흡연물품용 필터를 제조하였다.A filter for smoking articles was manufactured in the same manner as in Example 1, except that one hole was formed in the first filter part and the length was 9 mm, and the length of the second filter part was 18 mm.
비교예 1 내지 3 및 실시예 1, 2 의 필터 설계 내역을 하기 표 1 에 나타낸다.The filter design details of Comparative Examples 1 to 3 and Examples 1 and 2 are shown in Table 1 below.

상기 표에서 ME는 근위단부 쪽에 위치하는 제 1 필터부, TE는 원위단부 쪽에 위치하는 제 2 필터부를 의미한다.In the table above, ME refers to the first filter unit located at the proximal end, and TE refers to the second filter unit located at the distal end.
비교예 1 의 흡인저항과 대비하여, 실시예 1 의 흡인저항은 8.75 mmH2O/Tip 증가하고, 실시예 2 의 흡인저항은 47.75 mmH2O/Tip 증가한다. 즉, 실시예 2 의 흡인저항은 실시예 1 의 흡인저항에 비하여 좀 더 높은 값을 가지고, 이는 제 1 필터부 및 제 2 필터부가 15+12 mm 체제일 때보다 9+18 mm 체제일 때 흡인저항이 증가함을 의미한다. 실시예 1 과 달리 실시예 2 의 경우, 제 1 필터부의 길이가 9 mm이고, 천공은 근위단부로부터 통상 10.5 내지 11 mm에 위치하므로, 천공이 제 2 필터부에 위치하게 된다. 따라서, 실시예 2 의 경우 천공으로부터 유입된 공기가 제 2 필터부를 거쳐 제 1 필터부를 지나게 되어 흡인저항이 높아지는 것으로 예상된다.Compared to the suction resistance of Comparative Example 1, the suction resistance of Example 1 increases by 8.75 mmH 2 O/Tip, and the suction resistance of Example 2 increases by 47.75 mmH 2 O/Tip. That is, the suction resistance of Example 2 has a higher value than that of Example 1, which means that the suction is greater when the first and second filter units are 9+18 mm than when the first and second filter units are 15+12 mm. This means that resistance increases. Unlike Example 1, in Example 2, the length of the first filter part is 9 mm, and the perforation is usually located at 10.5 to 11 mm from the proximal end, so the perforation is located in the second filter part. Therefore, in the case of Example 2, it is expected that the suction resistance increases as the air flowing in from the perforation passes through the second filter unit and then the first filter unit.

실시예 2 는 비교예 1 과 대비하여 TPM 값은 0.59 mg/cig, 타르 값은 0.38 mg/cig, 니코틴 값은 0.03 mg/cig 만큼 감소하였다. In Example 2, compared to Comparative Example 1, the TPM value was reduced by 0.59 mg/cig, the tar value was reduced by 0.38 mg/cig, and the nicotine value was reduced by 0.03 mg/cig.
제 1 필터부 및 제 2 필터부가 9+18 mm 체제일 때, 15+12 mm 체제일 때에 비하여 TPM, 타르, 니코틴 이행량이 크게 감소하였다. 특히 타르와 니코틴의 경우, 제 1 필터부 및 제 2 필터부가 9+18 mm 체제일 때 비교예 1 대비 각각 23.1~24.4 %, 11.8~17.6 % 감소하는 유의미한 결과를 보였다. 이는 9+18 mm 체제의 흡인저항이 15+12 mm 체제의 흡인저항보다 높고, 통상 원위단부에 위치한 제 2 필터부 쪽의 연기성분 제거능이 크기 때문이다.When the first and second filter units were 9+18 mm, TPM, tar, and nicotine transfer amount were significantly reduced compared to the 15+12 mm system. In particular, in the case of tar and nicotine, when the first and second filter parts were 9 + 18 mm, a significant decrease of 23.1 ~ 24.4% and 11.8 ~ 17.6%, respectively, compared to Comparative Example 1 was shown. This is because the suction resistance of the 9+18 mm system is higher than that of the 15+12 mm system, and the smoke component removal ability of the second filter unit, which is usually located at the distal end, is greater.
실험예 2: 필터 적용에 따른 손냄새 저감 효과의 관능 평가Experimental Example 2: Sensory evaluation of the effect of reducing hand odor by applying a filter
본 발명의 필터를 적용하여 손냄새 저감 효과를 알아보기 위해 흡연 시 손가락 부위에 면장갑을 사용하고, 흡연 완료 1 시간 후 느껴지는 담배 냄새의 강도를 확인하기 위한 관능 평가를 실시하였다. 상기 면장갑은 흡연 직후 밀봉하여 시료봉투에 보관하였다. 냄새의 강도는 일반 천과 비교하였다.To determine the effect of reducing hand odor by applying the filter of the present invention, cotton gloves were used on the fingers when smoking, and a sensory evaluation was conducted to determine the intensity of the cigarette odor felt 1 hour after completion of smoking. The cotton gloves were sealed immediately after smoking and stored in a sample bag. The intensity of the smell was compared to regular cloth.
관능 평가는 비교예 1 및 실시예 2 의 필터가 적용된 흡연물품을 이용하여 15명의 평가 패널원을 대상으로 실시하였으며, 총 9점 만점을 기준으로 하였다.Sensory evaluation was conducted on 15 evaluation panel members using smoking articles to which the filters of Comparative Example 1 and Example 2 were applied, and a total score of 9 was used as the standard.
관능 평가 결과는 하기 표 5 및 표 6 에 도시하였다. 표 5 는 대응표본 통계량, 표 6 은 대응표본 검정 결과이다.The sensory evaluation results are shown in Tables 5 and 6 below. Table 5 is the paired sample statistics and Table 6 is the paired sample test results.

흡연 완료 후 관능 특성을 분석한 결과, 실시예 2를 적용한 흡연물품은 비교예 1 을 적용한 흡연물품에 비하여 이취강도가 48.3 % 감소하는 유의미한 결과를 보여주었다. 천공을 통해 공기가 들어오면 주류연은 통상 필터의 중앙으로 몰리게 되어, 실시예 2 를 적용한 흡연물품의 경우 3개의 홀을 통해 주류연이 빠져나감으로써 손냄새가 저감될 수 있음을 알 수 있다.As a result of analyzing the sensory characteristics after completion of smoking, the smoking article to which Example 2 was applied showed a significant decrease in off-flavor intensity by 48.3% compared to the smoking article to which Comparative Example 1 was applied. When air enters through the perforation, mainstream smoke is usually concentrated in the center of the filter, and in the case of the smoking article to which Example 2 is applied, it can be seen that hand odor can be reduced by allowing mainstream smoke to escape through three holes.
따라서, 실험예 1 및 2 에 따르면, 실시예 2 와 같이 다중홀 및 9+18 mm 체제를 흡연물품에 적용하는 경우, 타르, 니코틴 등의 연기성분을 줄이면서 손냄새를 저감 시킬 수 있을 것으로 예상할 수 있다.Therefore, according to Experimental Examples 1 and 2, when applying the multi-hole and 9+18 mm system to smoking articles as in Example 2, it is expected that hand odor can be reduced while reducing smoke components such as tar and nicotine. can do.
