Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cigarette packaging materials, and relates to tipping paper, specifically to a cigarette tipping paper with a permeable porous structure substrate. Background Technology
[0002] Tipping paper is generally used on cigarettes. Cigarette tipping paper is a special type of paper used to connect the cigarette filter to the cigarette. When in use, the tipping paper is rolled into a ring, with the width of the tipping paper aligned with the length of the cigarette.
[0003] Current cigarette tipping papers typically use base paper as the main material, generally white base paper made from natural fibers such as wood pulp and straw pulp. This lacks a porous structure and results in poor air permeability. Most existing cigarette tipping papers use a solid base material, with insufficient systematic design of the air permeability, leading to low air permeability efficiency. Subsequent processing techniques such as laser perforation are generally used to increase air permeability. Therefore, there is an urgent need to design a cigarette tipping paper with a porous base material.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0005] The purpose of this invention is to provide a cigarette tipping paper with a porous substrate.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A cigarette tipping paper with a permeable porous structure substrate, comprising:
[0008] The inner layer is composed of multiple fiber strips bonded together in sequence, with the fiber strips forming a first air-permeable gap;
[0009] The middle layer has multiple pores that extend through its thickness.
[0010] The outer layer is bonded to one side of the middle layer, the inner layer is bonded to the other side of the middle layer, and the outer layer and the inner layer are separate from each other;
[0011] The outer layer includes a first end and a second end. The first end has a hollow portion that extends through the width of the paper. When the inner layer at the second end is bonded to the first end, the hollow portion is compressed to form a second air-permeable gap.
[0012] In one alternative embodiment, the inner layer at the second end is adapted to be bonded to the first end so that the splicing paper forms a circle suitable for placement in the middle of the cigarette.
[0013] In one optional embodiment, the hollow portion extends through the width direction of the paper being dispensed; the cross-section of the hollow portion is rectangular or oblong.
[0014] In one alternative embodiment, the hollow portion is located at the middle of the first end;
[0015] The hollow section near the middle layer is bonded to the middle layer.
[0016] In one optional embodiment, the pores extend through the thickness direction of the intermediate layer;
[0017] The fiber strips are bonded to the intermediate layer.
[0018] In one optional embodiment, the pores are distributed in a linear array in both the length and width directions of the intermediate layer;
[0019] The axial direction of the fiber strip is parallel to the width direction of the intermediate layer, so that the straight direction of the fiber strip is consistent with the length direction of the cigarette.
[0020] In one alternative embodiment, the cross-section of the pores is a regular hexagon to give the intermediate layer sufficient strength;
[0021] The fiber strips are circular in diameter so that sufficient adhesive material can be held between the fiber strips and other fiber strips and the intermediate layer when the fiber strips are bonded.
[0022] In one alternative embodiment, the fiber strip is adapted to compress the hollow portion and bond to the edge of the hollow portion away from the intermediate layer during the splicing of the splice paper.
[0023] The fiber strips are plant fibers.
[0024] The beneficial effects of this utility model are as follows: It provides a cigarette tipping paper with a permeable pore structure substrate, which uses an inner layer, a middle layer, multiple pores and an outer layer in combination. That is, the gaps between the fiber strips in the inner layer, the pores in the middle layer and the permeable gaps after compression in the outer layer form a three-dimensional permeable channel, thereby achieving the effect of increasing the pore structure in the middle layer of the tipping paper and increasing the gaps in the outer and inner layers of the tipping paper. This increases the pore structure and gaps, and improves the permeability of the tipping paper. Attached Figure Description

[0035] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0036] refer to Figures 1 to 2 At least one embodiment provides a cigarette tipping paper with a permeable porous structure substrate, comprising: an inner layer 1, which is composed of a plurality of sequentially bonded fiber strips 11, wherein the adhesive material is distributed in strips during the bonding process to create gaps between the adhesive material and the fiber strips 11 to act as permeable pores; an intermediate layer 2, which includes a plurality of air holes 21 to increase air permeability; and an outer layer 3, which is bonded to one side of the intermediate layer 2, wherein the inner layer 1 is bonded to the other side of the intermediate layer 2, and the outer layer 3 includes a first end 31 and a second end 32, wherein the inner layer 1 at the second end 32 is adapted to be bonded to the first end 31, so that the tipping paper forms a circle suitable for placement in the middle of the cigarette, thereby improving the bonding strength and reducing the thickness of the tipping paper at the bonding point; a first permeable gap is formed between the fiber strips 11; and the outer layer 3 is provided with a gap to cooperate with the air holes 21 to improve the air permeability of the tipping paper.
[0037] In some embodiments, a hollow portion 33 is provided at the first end 31 so that after the inner layer 1 at the second end 32 is bonded to the first end 31, the hollow portion 33 is compressed, and the hollow portion is compressed to form a second air-permeable gap, which at the same time improves the bonding firmness and reduces the thickness of the bonding paper at the bonding point; the outer layer 3 is separated from the inner layer 1 to ensure that the outer layer 3, the middle layer 2 and the inner layer 1 are bonded in sequence.
[0038] In some embodiments, the hollow portion 33 extends through the width direction of the paper being dispensed; the cross-section of the hollow portion 33 is rectangular or oblong to facilitate processing.
[0039] In some embodiments, the hollow portion 33 is located in the middle of the first end 31 to ensure that the upper and lower sides of the hollow portion 33 are suitable for bonding with the outer layer 3 and the inner layer 1; the side of the hollow portion 33 near the middle layer 2 is bonded to the middle layer 2.
[0040] In some embodiments, the pores 21 extend through the thickness direction of the intermediate layer 2 to improve the air permeability of the intermediate layer 2; the fiber strip 11 is bonded to the intermediate layer 2.
[0041] In some embodiments, the air holes 21 are distributed in a linear array in both the length and width directions of the intermediate layer 2; the axial direction of the fiber strip 11 is parallel to the width direction of the intermediate layer 2, so that the linear direction of the fiber strip 11 is consistent with the length direction of the cigarette, thereby ensuring the strength of the tipping paper in the length direction of the cigarette.
[0042] In some embodiments, the cross-section of the pore 21 is a regular hexagon to give the intermediate layer 2 sufficient strength; the diameter of the fiber strip 11 is circular so that when the fiber strip 11 is bonded, the fiber strip 11 is suitable for holding enough adhesive material between the fiber strip 11 and other fiber strips 11 and the intermediate layer 2, and the inconsistent thickness of the fiber strip 11 improves the air permeability of the inner layer 1.
[0043] In some embodiments, when the tipping paper is bonded, the fiber strip 11 is adapted to compress the hollow portion 33 and bond it to the edge of the hollow portion 33 away from the intermediate layer 2; the fiber strip 11 is plant fiber, so that it burns synchronously when the cigarette is burned.
[0044] Working principle: When using a cigarette tipping paper with a permeable porous structure as the base material, the tipping paper is first brought into contact with the cigarette filter and the cigarette body. Then, before rolling, glue is applied to the first end 31 away from the fiber strip 11. The tipping paper is then rolled up along its length so that the width of the tipping paper is consistent with the length of the cigarette, i.e., the length of the fiber strip 11 is consistent with the cigarette rolling direction. This connects the filter and the cigarette body. During this process, when the fiber strip 11 at the second end 32 contacts the first end 31, the hollow part 33 in the first end 31 is compressed to form a groove, which facilitates the fitting of the fiber strip 11 at the second end 32. This achieves the bonding of the tipping paper.
[0045] Tests have shown that the air permeability of the splicing paper in this structure reaches 3000-5000 Coresta units, which is 200% higher than that of solid substrate.
