Description

Technical Field

[0001] This utility model relates to the field of tipping paper technology, and more specifically, to a cigarette tipping paper with a permeable porous structure substrate. Background Technology

[0002] Tipping paper is a key functional material in cigarette manufacturing. It is mainly used to connect the filter tip to the cigarette and plays a role in air permeability control, decoration, and anti-counterfeiting. Its technological development is closely related to reducing tar and harm in cigarettes, improving the consumer experience, and the evolution of industry regulations. The insufficient air permeability of existing tipping paper can easily affect the smoke dilution effect.

[0003] In existing technologies, cigarette tipping papers on the market have certain shortcomings in terms of air permeability. Poor air permeability leads to unsatisfactory smoke dilution during cigarette smoking, affecting the smoking experience and hindering the reduction of harmful components in the smoke. How to invent a cigarette tipping paper with a porous substrate to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cigarette tipping paper with a permeable porous structure substrate, aiming to solve the problem of insufficient air permeability in existing cigarette tipping papers.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a cigarette tipping paper with a permeable porous structure substrate, including a tipping paper comprising an outer paper base layer, a middle paper base layer, and an inner paper base layer, wherein holes are formed on the outer paper base layer, the middle paper base layer, and the inner paper base layer.

[0007] Preferably, the outer paper base layer has a first vent hole, the middle paper base layer has a connecting hole, and the inner paper base layer has a second vent hole.

[0008] Preferably, the diameter of the first vent is larger than that of the second vent, and the diameters of the two ends of the connecting hole are the same as those of the first vent and the second vent, respectively.

[0009] Preferably, the outer paper base layer, the middle paper base layer and the inner paper base layer are compositely bonded and fixed, and the first vent hole and the second vent hole are interconnected through the connecting hole.

[0010] Preferably, the surfaces of the outer paper base layer and the inner paper base layer are laminated with a reinforcing layer.

[0011] The beneficial effects of this utility model are:

[0012] Multiple paper base layers are perforated and then connected together, forming several irregularly shaped micropores on the tipping paper. The larger pores closer to the outside air increase the contact area with the outside air, allowing air to enter the vents more quickly and smoothly. At the same time, the smaller pores closer to the filter element, together with the transition effect of the connecting holes, buffer the incoming air to a certain extent, preventing air from passing through the vents too quickly. This achieves reasonable control of airflow rate, making the airflow within the vents more orderly. During the smoking process, this dilutes and mixes the smoke, achieving more precise and reasonable dilution of the smoke, thereby improving the smoking experience and helping to reduce the content of harmful components in the smoke.

[0013] Meanwhile, the micropores on the tipping paper are formed by splicing together multiple holes on the paper base layer, without directly punching through the tipping paper. This ensures the stability of the overall structure of the tipping paper, improves air permeability, and does not excessively weaken the physical strength of the tipping paper, reducing the possibility of damage during production and use.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example, refer to Figures 1-9 A tipping paper for cigarettes with a permeable porous structure substrate includes tipping paper 1, which comprises an outer paper base layer 11, a middle paper base layer 12, and an inner paper base layer 13. Holes are formed in the outer paper base layer 11, the middle paper base layer 12, and the inner paper base layer 13.

[0027] Furthermore, the outer paper base layer 11 is provided with a first vent hole 111, the middle paper base layer 12 is provided with a connecting hole 121, and the inner paper base layer 13 is provided with a second vent hole 131. The diameter of the first vent hole 111 is larger than that of the second vent hole 131. The diameters of the two ends of the connecting hole 121 are the same as those of the first vent hole 111 and the second vent hole 131, respectively. The outer paper base layer 11, the middle paper base layer 12, and the inner paper base layer 13 are bonded and fixed together. The first vent hole 111 and the second vent hole 131 are interconnected through the connecting hole 121. The surfaces of the outer paper base layer 11 and the inner paper base layer 13 are laminated with a reinforcing layer.

[0028] It should be noted that during the overall manufacturing of the tipping paper 1, multiple paper base layers are made of cork base paper. During production, several equidistant first ventilation holes 111, connecting holes 121, and second ventilation holes 131 are firstly laser-drilled on the surfaces of the outer paper base layer 11, the middle paper base layer 12, and the inner paper base layer 13. Then, the holes on the outer paper base layer 11 are aligned with the larger diameter end of the connecting hole 121 on the middle paper base layer 12. Next, the smaller diameter end of the connecting hole 121 is aligned with the second ventilation hole 131 on the inner paper base layer 13. The three are then bonded together and fixed. Finally, the paper is rolled with the inner paper base layer 13 as the inner side, thus forming several irregularly shaped micropores on the tipping paper 1. The first ventilation hole 111, which is closer to the outside air, has a larger diameter, increasing the contact area with the outside air, allowing air to enter the ventilation hole more quickly and smoothly. Meanwhile, the smaller diameter of the second ventilation hole 131, in conjunction with the connecting hole... The transition function of 121 buffers the incoming air to a certain extent, preventing it from passing through the vent too quickly, thus achieving reasonable control of airflow speed and making the airflow within the vent more orderly. During cigarette smoking, the smoker inhales, creating negative pressure, which lowers the internal pressure of the cigarette while the external air pressure is relatively high. Under the action of the pressure difference, the external air is driven to enter through the opening on the surface of the first vent 111, and then flows through the connecting hole 121 to the second vent 131, diffusing into the filter element inside the tipping paper 1. It encounters the smoke generated from the combustion end of the cigarette and flowing towards the filter tip. The numerous regularly arrayed vents work together, allowing a large amount of air to come into contact with the smoke in this way, thereby diluting and mixing the smoke, achieving more precise and reasonable dilution of the smoke, thus improving the smoking taste, and helping to reduce the content of harmful components in the smoke.

[0029] Meanwhile, the micropores on the tipping paper 1 are formed by splicing together multiple holes on the paper base layer, without directly drilling through the tipping paper 1. This ensures the stability of the overall structure of the tipping paper 1, improves air permeability, and does not excessively weaken the physical strength of the tipping paper 1, reducing the possibility of damage during production and use. Furthermore, the reinforcing layers on both sides of the tipping paper 1 are coated with nano-SiO2-acrylic resin composite material, which can stably absorb laser energy during the drilling process, ensuring the smoothness of the hole edges, avoiding limiting burrs from affecting airflow, and improving the overall bending resistance of the tipping paper 1, reducing the risk of tearing and thus improving the overall quality.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
