Description

Technical Field

[0001] The present invention relates to the field of tobacco products, and in particular to a composite filter rod and a cigarette. Background Art

[0002] Smoke modulation is the main purpose of using particle filter rods in the current cigarette industry. Adding functional material particles in the filter rod can change the content of certain substances in the smoke. For example, using activated carbon can absorb small molecular harmful substances such as benzene, formaldehyde, and xylene in the smoke. Using plant flavor particles can improve the taste of the smoke and bring a characteristic aroma.

[0003] However, the particle filter stick has limited effect on smoke modulation due to the limited amount of particles applied; and only applying a single type of particles cannot avoid the disadvantages of applying that type of particles, such as activated carbon particles will reduce the moisture and aroma of the smoke and make the taste lighter and drier, and flavor particles cannot remove small molecular harmful substances in the smoke.

[0036] refer to Figure 1 and Figure 2 Some embodiments of the present disclosure provide a composite filter rod, comprising a first filter rod segment 1 , a second filter rod segment 2 and a third filter rod segment 3 .

[0037] The first filter rod segment 1 includes a first matrix 10. The second filter rod segment 2 includes a matrix second matrix 20 and first functional material particles 21 required for modulating smoke, and the first functional material particles 21 are distributed in the matrix second matrix 20. In the length direction of the composite filter rod, a gap is formed between the first filter rod segment 1 and the second filter rod segment 2, and the third filter rod segment 3 includes a first wrapping 32 coated on the periphery of the gap and second functional material particles 31 required for modulating smoke filled in the gap. The first filter rod segment 1, the third filter rod segment 3 and the second filter rod segment 2 are arranged in sequence along the length direction of the composite filter rod.

[0038] The first filter rod segment 1 may further include additives such as popping beads and scented threads that can improve the taste of smoke. In addition, the first filter rod segment 1 may be composed of a plurality of filter layers coaxially nested inside and outside.

[0039] Optionally, the first substrate 10 and the second substrate 20 can be filled with filter materials. In some embodiments, the filter material includes acetate fiber, polypropylene fiber or other fiber materials and non-woven materials that can reduce the content of harmful substances in smoke. The filter materials in the first substrate 10 and the second substrate 20 can be the same or different.

[0040] Some embodiments of the present disclosure further provide a cigarette, comprising the aforementioned composite filter rod and a tobacco shred segment 5. The tobacco shred segment 5 is connected to an end of the second filter rod segment 2 that is away from the first filter rod segment 1.

[0041] That is to say, the first filter rod segment 1 is arranged at the proximal lip end of the composite filter rod, and the second filter rod segment 2 is arranged at the tobacco end of the composite filter rod.

[0042] In order to prevent the functional material particles from entering the consumer's mouth when smoking the cigarette, in some embodiments, the first filter rod segment 1 does not include the functional material particles.

[0043] In some embodiments, the first functional material particles 21 include at least one of the following: adsorption material particles, fragrance material particles, and moisturizing material particles.

[0044] In some embodiments, the second functional material particles 31 include at least one of the following: adsorption material particles, fragrance material particles, and moisturizing material particles.

[0045] Adsorption material particles are used to absorb harmful components in the smoke, reducing the smoke tar and harm, such as activated carbon. Fragrance material particles are used to add characteristic aroma to the smoke, giving the smoke flavor characteristics. Moisture-retaining material particles are used to increase the moistness of the smoke.

[0046] In some embodiments, the first functional material particles 21 and the second functional material particles 31 have the same composition.

[0047] For example, in order to further enhance the adsorption effect of the composite filter rod on smoke, the first functional material particles 21 and the second functional material particles 31 can both be made of adsorption material particles.

[0048] In some embodiments, the first functional material particles 21 and the second functional material particles 31 have different compositions.

[0049] For example, under the premise that the composite filter rod meets the requirements for the interception capacity of harmful substances in the flue gas, the first functional material particles 21 are made of adsorbent material particles, and the second functional material particles 31 are made of flavor material particles, so that the composite filter rod can take into account the needs of flue gas filtration and flue gas flavor modulation. For another example, the first functional material particles 21 are made of adsorbent material particles, and the second functional material particles 31 are made of moisturizing material particles, so as to reduce the adverse effects of adsorbent material particles such as activated carbon on the moisture and aroma of flue gas. In the case where the first functional material particles 21 are made of adsorbent material particles, since the first functional material particles 21 are located upstream of the second functional material particles 31 along the direction of flue gas flow, the composite filter rod will first absorb harmful substances in the flue gas, and then release aroma components or moisturizing components into the flue gas, thereby avoiding the aroma components or moisturizing components being adsorbed and reducing the modulation effect on the flue gas.

[0050] In the above embodiment, the first functional material particles 21 and the second functional material particles 31 have different compositions, which can not only take into account different smoke modulation requirements, but also reflect the application order of the functional materials and reduce the mutual influence of the modulation effects of different functional materials.

[0051] It can be seen that the second filter rod segment 2 and the third filter rod segment 3 of the composite filter rod provided in the embodiment of the present disclosure can apply the same or different functional material particles, thereby improving the modulation effect of the functional material particles on the flue gas by increasing the amount of particles applied, the type of application, the order of application, etc.

[0052] Furthermore, the second functional material particles 31 are directly filled in the gap between the first filter rod segment 1 and the second filter rod segment 2 rather than being distributed in the filter material, which can increase the application amount of the second functional material particles 31 and make the smoke modulation effect of the second functional material particles 31 more obvious.

[0053] The cigarette provided by the embodiments of the present disclosure has the advantages of the aforementioned composite filter rod.

[0054] In some embodiments, reference Figure 2 The first substrate 10 has a groove 103 on its periphery, and the composite filter rod includes a second wrapper 11 , which is coated on the surface of the groove 103 and is configured to filter smoke flowing through the second wrapper 11 .

[0055] Optionally, the second wrapper 11 is wrapped around the outer periphery of the first substrate 10, and the shape of the second wrapper 11 is adapted to the groove 103. Optionally, the second wrapper 11 is disposed between the first substrate 10 and the molding paper.

[0056] In the above embodiment, the first filter rod segment has a groove and the first wrapper is coated on the surface of the groove. The resistance of smoke passing through the groove is much smaller than the resistance passing through the inside of the first filter rod segment. Therefore, after the smoke flows into the first filter rod segment, it will flow into the groove through the first wrapper. Therefore, the smoke can be subjected to the dual filtering effect of the filter material in the first filter rod segment and the first wrapper, which is beneficial to improve the interception effect of the composite filter rod on harmful substances in the smoke and better meet the development needs of cigarette tar reduction. The first filter rod segment in the above form can share the pressure of the second filter rod segment and the third filter rod segment to intercept harmful substances, leaving space for the second filter rod segment and the third filter rod segment to adjust the taste of the smoke.

[0057] The second filter rod segment and the third filter rod segment can be filled with adsorption materials of the same composition to further enhance the adsorption capacity of harmful substances in smoke; or at least one of the first functional material particles or the second functional material particles can be replaced with a flavor material to meet the taste modulation needs of different types and different orders.

[0058] In some embodiments, the first substrate 10 is divided into a grooved section 101 and a non-groove section 102 along the length direction of the composite filter rod, and the groove 103 runs through both ends of the grooved section 101 .

[0059] By providing the grooved section 101 and the non-grooved section 102, the smoke will pass through the first wrapper 4 when flowing between the grooved section 101 and the non-grooved section 102, so that harmful substances in the smoke can also be intercepted. In addition, the non-grooved section 102 can block the second functional material particles 31, preventing the second functional material particles 31 from falling out of the composite filter rod from the groove 103.

[0060] In some embodiments, reference Figure 2 The grooved section 101 is located at an end of the first substrate 10 away from the third filter rod section 3 .

[0061] In the above embodiment, the groove section 101 is located at the proximal lip end of the composite filter rod, and consumers can see the groove 103 from the end of the proximal lip end of the composite filter rod, which is beneficial to improving the visual recognition of the composite filter rod and improving the grade of the cigarette product.

[0062] In some embodiments not shown in the figures, the grooveless section 102 is located at an end of the first substrate 10 away from the third filter rod section 3 .

[0063] In some embodiments, reference Figure 1 and Figure 2 The groove 103 extends along the length direction of the composite filter rod.

[0064] In some embodiments not shown in the figure, the extending direction of the groove 103 may also form an angle with the length direction of the composite filter rod. The groove 103 may be in a straight line or a curve.

[0065] In some embodiments, reference Figure 2 , a plurality of grooves 103 are evenly distributed on the outer circumference of the first substrate 10 .

[0066] By providing a plurality of evenly distributed grooves 103 , smoke can be more evenly distributed in the circumferential direction when flowing through the first filter rod segment 1 , which is conducive to fully exerting the filtering effect of the filter materials in different parts of the first filter rod segment 1 .

[0067] In the above embodiment, the second functional material particles 31 can be directly filled in the gap between the first filter rod segment 1 and the second filter rod segment 2 instead of being distributed in the filter material, which can increase the application amount of the second functional material particles and make the effect of the second functional material particles in modulating the smoke more obvious.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution for protection requested by the present disclosure.
