The same reference numerals used throughout the drawings indicate the same or similar parts.

[0044] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0045] Reference Figures 1 to 7 A mosquito coil packaging cylinder, comprising: a cylinder body 1 and a cylinder bottom 2,

[0046] In one embodiment, the barrel 1 is fixedly connected around the barrel bottom 2, and a curling structure 11 is provided at the opening of the barrel 1; the barrel 1 has a taper; the barrel is a paper-plastic material with a base paper film PE coating. Preferably, the taper of the barrel 1 is less than 1°, and the barrel 1 is unfolded into a fan shape.

[0047] Among them, by using paper plastic material to make the cylinder body 1 with a curling structure 11 and a taper, the stability of the cylinder body 1 structure is enhanced. The cylinder body 1 is provided with a certain taper, and the curling structure 11 is provided at its opening, which is conducive to enhancing the support of the cylinder body 1; using paper plastic material to make the cylinder body 1 is conducive to waterproofing and moisture-proofing of the cylinder body 1, while reducing the cost of the cylinder body 1. The mosquito coil 5 packaging cylinder and its manufacturing method have the characteristics of stable cylinder body 1 structure, good protection performance and low cost.

[0048] In one embodiment, the paper-plastic material is relatively light, easy to transport and use, and can be recycled, meeting environmental protection requirements. Due to the addition of plastic, the paper-plastic cylinder has a certain waterproof performance, and the surface of the paper-plastic cylinder is suitable for various printing technologies, and can achieve rich patterns and colors. The paper-plastic cylinder combines the advantages of paper and plastic and is suitable for a variety of application scenarios.

[0049] In one embodiment, the thickness of the curling structure 11 is 3-8 times the thickness of the barrel 1, and the curling structure 11 is located at the inner periphery of the barrel 1. The curling structure 11 is inwardly rolled, which is more beautiful and coordinated in appearance compared with conventional outwardly rolled paper cups, and also saves space.

[0050] In one embodiment, referring to Figure 2 As shown, the curling structure 11 includes at least one first arc portion 12 and a second arc portion 13, the first arc portion 12 curls from top to bottom, the second arc portion 13 curls from bottom to top, the first arc portion 12 and the second arc portion 13 are integrally arranged, the diameter of the first arc portion 12 is greater than the diameter of the second arc portion 13, and the outer wall of the second arc portion 13 is fixedly connected to the inner wall of the barrel 1 through the PE coating. An arc-shaped hollow area is provided inside the curling structure 11, which is conducive to increasing the stability of the barrel 1 itself.

[0051] In one embodiment, referring to Figure 3 As shown, the cylinder body 1 also includes a first fold 14, which is U-shaped, and the cylinder bottom 2 includes a second fold 21, which is L-shaped, and the short side of the second fold 21 is inserted into the U-shaped interior of the first fold 14. The first fold 14 and the second fold 21 are connected by a PE coating to form a support foot 3, and the inner wall of the support foot 3 is provided with an impression, which is recessed from the first fold 14 inward to the second fold 21. Preferably, the impression is a wave bending structure, which helps to form a tighter fit after the first fold 14 and the second fold 21 are connected, reduces the penetration of air or liquid, and improves the sealing performance of the cylinder. Through the processing of the wave bending structure, the bottom 2 of the paper tube can better disperse the pressure when subjected to external force, maintain the stability of the structure, prevent deformation or damage due to uneven force, and enhance its overall performance.

[0052] In one embodiment, the cylinder body 1 and the cylinder bottom 2 form a receiving cavity 4 for placing the mosquito coil 5. Preferably, since the taper of the cylinder body 1 is less than 1°, the space in the receiving cavity 4 is substantially consistent from top to bottom, and after the mosquito coil 5 is loaded, the gap between the mosquito coil 5 and the inner wall of the cylinder body 1 is substantially consistent, and the packaging performance is more stable. Less space is wasted during packaging, and more packaging space is saved.

[0053] A mosquito coil box, suitable for the above-mentioned mosquito coil packaging cylinder, referring to Figure 4-Figure 5As shown, the mosquito coil box further includes a cylinder cover 6 detachably connected to the cylinder body, the cylinder cover 6 includes a concave structure for abutting the mosquito coil, the concave structure extends into the cylinder body 1; the concave structure includes four first abutting portions 61, and the four first abutting portions 61 are arranged around the center of the cylinder cover 6. Preferably, it also includes a strap, which is used to tie the cylinder body and the cylinder cover 6 tightly, so that the concave structure and the mosquito coil are abutted against each other.

[0054] In one embodiment, the barrel cover 6 also includes a cover edge 63 adapted to the opening of the barrel body 1, and the cover edge 63 is located at the periphery of the barrel cover 6, and the inner diameter of the cover edge 63 is greater than the outer diameter of the opening of the barrel body 1. The length of the cover edge 63 is greater than the length of the concave structure, and the cover edge 63 is used to surround the opening of the barrel body 1. Since the curling structure 11 is located at the inner periphery of the barrel body 1, when the barrel cover 6 is covered on the barrel body 1, the cover edge 63 and the outer side of the barrel body 1 are attached together, so that the packaging paper plastic box is more beautiful and coordinated in appearance as a whole. Different from the barrel body 1 with the curling structure 11 rolled outward, there is a gap between the cover edge 63 and the barrel body 1, and the overall visual effect of being larger at the top and smaller at the bottom is presented, resulting in an overall unsightly appearance, and in the process of mass transportation, it also causes a waste of space. Due to the gap between the cover edge 63 and the barrel body 1, dust enters the accommodating chamber 4.

[0055] In another embodiment, referring to Figure 6-Figure 7 As shown, the concave structure further includes a second abutting portion 62, which includes a first protrusion 621 and a second protrusion 622. The second protrusion 622 is located at the center of the cylinder cover 62, and the second protrusion 622 is located inside the first protrusion 621. The first protrusion 621 is used to press against the outer ring of the mosquito coil 5, and the second protrusion 622 is used to press against the inner ring of the mosquito coil 5. Preferably, there is an upward protrusion between the first protrusion 621 and the second protrusion 622, and two fingers are respectively inserted into the first protrusion 621 and the second protrusion 622, which is convenient for the user to take the cover.
