Description

Technical Field

[0001] This application relates to the field of tipping paper technology, and more specifically to a hot stamping tipping paper. Background Technology

[0002] Tipping paper is a special industrial paper used for the sealing and packaging of cigarette filters. Also known as "tipping paper," it is made from tipping base paper through printing, coating, and other processes. It combines practicality and decoration and is an important component of cigarette packaging.

[0003] There is a type of hot-stamped tipping paper, such as... Figure 1 As shown, the paper includes a base paper layer 90, a background printing layer 91, a food-grade ink layer 92, and a hot stamping layer 93 arranged in sequence. It should be noted that the background printing layer 91 and the food-grade ink layer 92 are obtained on the base paper layer 90 through ink printing, and the hot stamping layer 93 is obtained at one end of the food-grade ink layer 92 through hot stamping. However, because the hot stamping layer 93 has a certain thickness, it has a slightly raised feel. Therefore, another type of cork paper with a hot stamping layer 93 is now available, such as... Figure 2 and Figure 3 As shown, it includes a base paper layer 90, a background printing layer 91, and a food-grade ink layer 92 arranged in sequence. The base paper layer 90 has a groove 901, and the background printing layer 91 has a first concave arc segment 911. The food-grade ink layer 92 has a second concave arc segment 921, and a hot stamping layer 93 is provided on the second concave arc segment 921. It should be noted that when the groove 901 is pressed into the base paper layer 90 by the press, the two ends of the groove 901 have inclined transition surfaces 9011. This makes it easy for the ink to slide off and accumulate at the ends of the groove 901, the first concave arc segment 911, and the second concave arc segment 921 under the action of gravity when the base paper layer 90 is printed with ink to form the background printing layer 91 and the food-grade ink layer 92. This causes the ink thickness accumulated in the first concave arc segment 911 and the second concave arc segment 921 to gradually increase, and the length of the bottom plane portion of the second concave arc segment 921 to become shorter. As a result, the length of the plane portion of the hot stamping layer 93 is shorter.

[0004] Therefore, there is a need for a hot stamping tipping paper with a flat surface and a longer flat portion of the hot stamping layer for the same groove length. Summary of the Invention

[0005] The main objective of this application is to provide a hot-stamping tipping paper for connecting a filter tip and cigarette paper. The hot-stamping tipping paper comprises a base paper layer, a background printing layer, a food-grade ink layer, and a hot-stamping section arranged in sequence. The base paper layer has a groove at one end near the cigarette paper. The two end walls of the groove are inclined transition surfaces. The bottom wall of the groove is convex and arc-shaped, and the two ends of the groove have first concave angles. The background printing layer has a first concave arc segment, and the food-grade ink layer has a second concave arc segment. The hot-stamping section is located within the second concave arc segment, and the highest point of the hot-stamping section is flush with the food-grade ink layer. The hot-stamping section includes a hot-stamping layer. By setting the groove and making the bottom wall of the groove convex and arc-shaped, a smooth surface is achieved, and for the same groove length, the planar portion of the hot-stamping layer has a longer length.

[0006] Another objective of this application is to provide a hot-stamping type tipping paper, wherein the two ends of the groove have a plurality of first vent holes and second vent holes respectively, the first vent holes are located at the end of the groove near the cigarette paper, and the diameter of the first vent holes is larger than the diameter of the second vent holes, and the vent holes are arranged more reasonably according to the distance of the vent holes from the opening.

[0007] To achieve at least one of the above-mentioned objectives, this application provides a hot-stamping tipping paper for connecting a filter tip and cigarette paper, wherein the hot-stamping tipping paper comprises:

[0008] The base paper layer, the background printing layer, and the food-grade ink layer are stacked in sequence. The base paper layer has a groove at one end near the cigarette paper.

[0013] In one or more embodiments of this application, the hot stamping portion further includes a varnish protective layer, which is located on the side of the hot stamping layer opposite to the coating layer.

[0014] In one or more embodiments of this application, the bottom wall of the first concave segment has second concave angles at both ends, and the volume of the second concave angle is smaller than the volume of the first concave angle.

[0015] In this embodiment, the hot-stamping tipping paper includes a base paper layer, a background printing layer, a food-grade ink layer, and a hot-stamping section arranged in sequence.

[0026] Indicative hot stamping tipping paper, for reference. Figures 4 to 5 According to a preferred embodiment of the present invention, a hot stamping type tipping paper is used to connect a filter tip and a cigarette paper, comprising a base paper layer 10, a background printing layer 20, and a food-grade ink layer 30 arranged in sequence.

[0027] Specifically, the base paper layer 10 has a groove 101 at one end near the cigarette paper. The two end walls of the groove 101 are inclined transition surfaces 1011. The bottom wall of the groove 101 is convex arc-shaped, and the two ends of the groove 101 have a first concave angle 1012. The background printing layer 20 has a first concave arc segment 201, and the food-grade ink layer 30 has a second concave arc segment 301. The two ends of the bottom wall of the first concave arc segment 201 have a second concave angle 2011.

[0028] In addition, the hot-stamping tipping paper also includes a hot-stamping section 40, which is located within the second concave arc segment 301, and the highest point of the hot-stamping section 40 is flush with the food-grade ink layer 30; the hot-stamping section 40 includes a hot-stamping layer 401.

[0029] It should be noted that the background printing layer 20 is obtained by gravure printing on the base paper layer 10 with alcohol-soluble ink, and is used to print fine background patterns, such as patterns or brand logos, on the base paper layer 10. Subsequently, food-grade ink is printed on the background printing layer 20 by gravure printing to cover the base color of the base paper layer 10 and enhance the overall aesthetics of the hot stamping tipping paper. It should also be pointed out that because the base paper layer 10 has the groove 101 and the transition surface 1011 is an inclined surface, the ink is printed on the transition surface... On surface 1011, ink slides down under the influence of weight and accumulates at the connection between the bottom wall of the groove 101 and the transition surface 1011. Since the bottom wall of the groove 101 is convex and has the first concave angle 1012 at both ends, the ink that slides down due to weight accumulates in the first concave angle 1012, naturally forming the second concave angle 2011 at both ends of the first concave arc segment 201. It should be noted that by setting the angle of the protruding portions at both ends of the external molding surface to a predetermined angle, the pressed groove 101... After printing the background printing layer 20, the volume of the second concave angle 2011 is made smaller than the volume of the first concave angle 1012, and after printing the food-grade ink layer 30, the concave portions of the top surface of both ends of the food-grade ink layer 30 are close to the plane. It is easy to see that by setting the groove 101, after two ink printings, the ink that slips down gradually fills the groove 101, so that after printing the food-grade ink layer 30, both ends of the second concave arc segment 301 are close to the plane, so that the hot stamping layer 401 can be hot stamped flat. The surface area is relatively large. In the prior art, since the bottom wall of the groove 101 is flat, ink accumulates at the connection between the bottom wall of the groove 101 and the transition surface 1011. After each ink printing, the arc angle of the ink accumulated at this connection becomes larger and occupies the length of the flat part of the second concave arc segment 301, resulting in a smaller flat area that can be hot-stamped on the hot stamping layer 401. In view of this, by setting the groove 101, this application has the advantages of a flat surface and a longer flat part of the hot stamping layer for the same groove length compared to the prior art.

[0030] Furthermore, to ensure a firm adhesion between the hot stamping layer 401 and the second concave arc segment 301, the hot stamping portion 40 further includes a coating layer 402. The coating layer 402 is located between the hot stamping layer 401 and the bottom wall of the second concave arc segment 301. The coating layer 402 is preferably a thermoplastic resin, such as polyacrylate. During the hot stamping process, the coating layer 402 softens and causes the hot stamping layer 401 to adhere to the second concave arc segment 301.

[0031] Furthermore, the hot stamping part 40 also includes a varnish protective layer 403, which is located on the side of the hot stamping layer 401 that is away from the coating layer 402.

[0032] It should be noted that the varnish protective layer 403 is applied to the surface of the hot stamping layer 401 by applying water-based varnish using special equipment. After the water-based varnish forms a film, an elastic film is formed on the surface of the hot stamping layer 401, namely the varnish protective layer 403, to prevent the hot stamping layer 401 from being damaged by external friction or in a humid environment.

[0033] Furthermore, the two ends of the groove 101 are respectively provided with a plurality of first vent holes 1013 and second vent holes 1014. It should be noted that by providing the first vent holes 1013 and the second vent holes 1014, the user can draw in some air from the outside while inhaling the smoke through the first vent holes 1013 and the second vent holes 1014, thereby reducing the amount of smoke ingested each time.

[0034] Furthermore, the first vent 1013 is located at one end of the groove 101 near the cigarette paper, and the diameter of the first vent 1013 is larger than the diameter of the second vent 1014.

[0035] It should be noted that, since the second vent 1014 is closer to the user's lips when the user is inhaling, by making the diameter of the second vent 1014 smaller than that of the first vent 1013, the hole closer to the user's mouth is smaller in each puff, so that less air can be inhaled per unit time, the ratio of smoke to outside air is more balanced overall, and the taste will not feel weak when inhaling.

[0036] In summary, the hot stamping tipping paper described in the embodiments of this application is explained, which provides advantages such as a smooth surface and a longer flat portion of the hot stamping layer for the same groove length.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
