Abstract
Description
Technical Field
[0001] The utility model relates to cigarettes, in particular to the manufacture of filter-tipped cigarettes. Background Art
[0002] "Classic" filter cigarettes are widely known in reality and basically consist of a cigarette wrapped in paper and a filter attached to one end of the cigarette. In addition, regardless of the filter material or combination of these materials used, and regardless of the structure of the filter, the filter (absorbent) material is included at the edge of the packaging and has a length of 15 to 22 mm.
[0003] Conventional cigarettes are also known, which have a rod-shaped tobacco portion and a filter tube connected to one end thereof, the total length of the filter tube being 25 to 35 mm, wherein the length of the rod is 5 to 7 mm [1].
[0004] The technical solution closest to the filter cigarette proposed in this application is a thin cigarette comprising a rod-shaped tobacco portion wrapped in cigarette paper and a filter connected to one end thereof. The filter comprises a filter element on the cigarette side and another filter element on the mouth side. The cigarette has a diameter of about 4 to 7 mm and delivers about 1 mg of condensate or not more than 0.2 mg of nicotine in the smoke. The filter is characterized in that the entire length of the filter is about 25 to 40 mm and the filter element on the cigarette side is about 10 to 25 mm. According to another form of known cigarette structure, the filter also has a filter element located between the two filter elements, which filter element contains carbon and has a length of about 5 to 15 mm [2].
[0005] Regardless of the structural features of the above-mentioned popular cigarettes, and regardless of the degree to which the condensate content or nicotine content in the smoke is reduced after being transported through them, these popular cigarettes have certain disadvantages that may cause hygiene and comfort problems for smokers when smoking. In particular, the filter tips of known cigarettes are relatively short in size and cannot provide sufficient cooling for the smoke inhaled by the smoker, which does not help reduce the condensate contained in the inhaled smoke and, therefore, does not reduce the nicotine content. Therefore, popular cigarettes cannot help reduce the damage caused by cigarette smoke to the smoker's body. In addition, when smoking with a relatively short filter tip, the smoker's fingers holding the cigarette will be close to the burning part of the cigarette, come into contact with the cigarette smoke, and be soaked by the condensate contained in the smoke, so that the fingers will turn yellow and smell of smoke. Utility Model Content
[0006] The purpose of the utility model is to ensure the hygienic and comfortable use of filter cigarettes and to reduce the damage of cigarette smoke to the body of the smoker.
[0007] The solution to the above-mentioned problem and the technical result are achieved by providing a cigarette structure having a filter, wherein the structure comprises a rod-shaped tobacco portion and a filter comprising at least two segments connected to one end of the tobacco portion. The cigarette has a total length of 100 to 125 mm, and the ratio of the total length of the filter to the length of the tobacco portion is 0.67 to 1.5. The free end segment of the filter is a hard-walled tube, and the length of the free end segment accounts for at least 8% of the total length of the filter.
[0008] The free end segment and the adjacent segment of the filter are realized in the form of a single element or in the form of a plurality of separate elements. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The accompanying drawings are useful for understanding the present application, in which:
[0010] Figure 1 shows an overall view of a filter cigarette having an embodiment of filter and tobacco portions of equal length;
[0011] Figure 2 shows a longitudinal section of a filter cigarette having a filter made of two separate elements;
[0012] Figure 3 Shown is a longitudinal section of a filter cigarette having a filter made from three separate elements. DETAILED DESCRIPTION
[0013] The filter cigarette has a round rod-shaped tobacco portion (1), and a filter (2) is connected to one end of the tobacco portion (1), and the filter (2) has no less than two sections. In addition, the free end section of the filter (2) is a tube (3) with a hard wall. The tube (3) and the monoacetate section (4) of the filter adjacent to the tube (3) can be realized in the form of a single component ( Figure 1 ), can also be realized in the form of a single element tube (3) and a single element monoacetate section (4), or can be realized by any combination of additional elements ( Figure 2 and Figure 3 For example, as an additional element of the filter (2), the acetate segment (5) can be made of activated carbon, or can contain activated carbon and / or any other adsorbent (such as perlite). The length of the tube (3) is at least 8% of the total length of the filter. The size of the filter may vary depending on the requirements and importance of the product to be discharged.
[0014] According to the present application, the total length of the cigarette can be between 100 mm and 125 mm. In addition, the ratio of the total length of the filter (2) to the length of the tobacco portion of the cigarette is 0.67-1.5. Based on the characteristics of the tobacco portion (1) of the filter (2) and the size of the tobacco portion, this ratio can provide a large number of opportunities for selecting the structure of the filter (2), its structural elements and dimensions, so as to ensure that the nicotine content in the smoke inhaled by the smoker is as expected.
[0015] In the implementation of this application, based on the length (L) of the cigarette, the total length of the filter (Lf) is calculated as follows:
[0016] Where k is a number between 0.67 and 1.5, that is, Lf =( KX ): (1+K);
[0017] If L is 100 and K is 0.67, the total length of the filter will be 67:1.67, or 40.11 mm. Similarly, the following data is obtained.
[0018] In this case, a cigarette with a total length of L = 100 mm may have the following parameters:
[0019] Total filter length: about 40 to 60 mm,
[0020] Length of tobacco part: about 60 to 40 mm,
[0021] Rod length: not less than 3.2 to 4.8 mm.
[0022] A cigarette with a total length of L = 125 mm may have the following parameters:
[0023] Total filter length: about 50 to 75 mm,
[0024] Length of tobacco part: about 75 to 50mm,
[0025] Length of rod: not less than 4 to 6 mm.
[0026] Based on the given data, it can be concluded that the proposed cigarette filter (2) of 100 to 125 mm in length can be selected from any value within the range of approximately 40 to 75 mm, which value is selected based on the specific requirements of the cigarette. In this case, the length of the tobacco portion is determined by the difference between the total length of the selected cigarette and the total length of the filter (2).
[0027] The length of the tube (3) can also be selected within a considerable range, depending on the size of the remaining segments installed in the filter (2). The filter (2) can be made of various materials and can also be made in different sizes.
[0028] Selecting a filter adapted to the specific situation for a cigarette of a given total length based on the recommended ratio of filter (2) to tobacco portion (1) ensures the practical functionality of a cigarette filter produced to specific requirements while ensuring the desired rod length.
[0029] Therefore, the cigarette having the structure proposed in this application should include important features such as hygiene requirements and have the following features for ease of use:
[0030] 1. Due to the length of the cigarette filter, the temperature of the smoke inhaled by the user is significantly reduced, resulting in less condensate transported to the user (smoker) along with the cigarette smoke, thereby reducing nicotine, which in turn reduces the damage caused by smoking to the smoker's body;
[0031] 2. To a certain extent, cigarette filters ensure that cigarette smoke is removed from the smoker's eyes and reduce the impact of smoke on the smoker's vision;
[0032] 3. Keep your fingers holding the cigarette as far away from the burning part as possible to reduce the possibility of burning your fingers;
[0033] 4. Significantly reduce the possibility of the fingers holding the cigarette being soaked by the condensate contained in the smoke during smoking, greatly reducing the possibility of the smoker's fingers turning yellow and smelling of smoke;
[0034] 5. Functionally, this application allows the fingers holding a cigarette to be as far away from the burning part of the cigarette as possible, thereby eliminating the risk of the gloves burning due to the burning cigarette when holding a cigarette with the gloves, and also eliminates the impact of residual smoke odor on the gloves;
[0035] 6. From a hygienic perspective, keeping your fingers away from the burning surface can safely extinguish the cigarette and prevent your fingers from coming into contact with the ashes remaining from the burning cigarette.
[0036] Besides this, the proposed structure, i.e. the filter cigarette, has an elegant appearance, which is particularly important for high-value cigarettes and women's cigarettes.
