Description

냉각용 필터 및 이를 포함하는 흡연 물품Cooling filter and smoking articles including the same
본 발명은, 냉각용 필터 및 이를 포함하는 흡연 물품에 관한 것이다. The present invention relates to a cooling filter and a smoking article comprising the same.
가열형 스틱제품의 경우, 매질부(각초 등 담배원료 및 향료 등이 포함된 끽미 및 에어로졸 생성물품을 포함)의 끽미 발현을 위해서 전용 디바이스를 활용한 가열이 필수이다. 끽미 발현을 위해 지금까지 개발된 가열형 스틱 전용 디바이스의 경우 매질부 내부까지의 열전달을 고려해 고온가열이 가능하도록 온도프로그램이 설계되어 있다. 가열온도는 보통 200 ℃ ~ 400 ℃ 수준이며, 각초를 태워서 흡입하는 전통형 궐련과 달리, 디바이스를 통해 매질부의 스틱을 가열할 때 다량의 수증기가 함께 발현된다. 가열을 통해 매질부 내부에서 발현되는 온도 수준은 100 ℃~ 200℃ 수준이다. 매질부 내부에서 생성되는 기류온도도 유사하고, 매질부 하류에 냉각소재가 없으면 뜨거운 열기를 흡연자가 흡입할 수 있다.In the case of a heated stick product, heating using a dedicated device is essential to express the taste of the medium (including tobacco raw materials such as cutweed and aerosol products containing spices and spices). In the case of devices exclusively for heating sticks that have been developed so far to express taste, the temperature program is designed to enable high-temperature heating in consideration of heat transfer to the inside of the medium part. The heating temperature is usually between 200 ° C and 400 ° C. Unlike traditional cigarettes, which burn and inhale cutting wax, a large amount of water vapor is released when the stick of the medium is heated through the device. The temperature level developed inside the medium part through heating is at the level of 100 ° C to 200 ° C. The temperature of the air flow generated inside the medium part is also similar, and if there is no cooling material downstream of the medium part, the smoker can inhale the hot heat.
이에 따라 새로운 가열형 스틱의 경제성 및 기능을 개선시킬 수 있는, 냉각 소재의 개발을 위한 연구가 활발하게 진행되고 있다.Accordingly, research for the development of a cooling material capable of improving the economy and function of a new heating stick is being actively conducted.

그 결과, 코팅된 지관을 사용한 실시예 1 내지 6에서 현저한 초기 온도 감소 효과가 확인되었다. 특히, 염화나트륨 코팅을 사용하는 실시예 3 내지 6에서 특히 우수한 온도 감소 효과가 확인되었다.As a result, a significant initial temperature reduction effect was confirmed in Examples 1 to 6 using the coated paper tubes. In particular, in Examples 3 to 6 using the sodium chloride coating, a particularly excellent temperature reduction effect was confirmed.

비교예 1과, 냉각 효과가 우수한 것으로 확인된 염화나트륨의 농도에 따른 관능특성을 확인하기 위해, 비교예 1 및 실시예 3 내지 6에 따른 초기퍼프 시 열감, 무화량, 빨림성에 대한 관능평가를 실시하였고 그 결과를 표 2에 나타냈다. 관능평가는 제조 후 2주가 경과된 실시예별 궐련들을 이용하여 25명의 평가 패널원을 대상으로 실시하였으며, 총 5점 만점을 기준으로 하였다.In order to confirm the sensory characteristics according to the concentration of sodium chloride confirmed to be excellent in Comparative Example 1 and the cooling effect, sensory evaluation was performed on the feeling of heat, amount of smoke, and sucking property at the time of the initial puff according to Comparative Example 1 and Examples 3 to 6 and the results are shown in Table 2. Sensory evaluation was conducted on 25 evaluation panel members using cigarettes for each example 2 weeks after manufacture, based on a total score of 5 points.

상기 결과로부터, 코팅되지 않은 지관과 무화량 및 빨림성에 있어서는 차이가 없거나 유사 수준이며, 염화나트륨의 함량이 높아질수록 초기 퍼프시 열감이 현저히 감소하는 것을 알 수 있었다.From the above results, it can be seen that there is no difference or a similar level to the uncoated paper tube in terms of atomization amount and absorbency, and that the higher the sodium chloride content, the greater the heat sensation during the initial puff.
