Description

Technical Field

[0001] The present invention relates to the technical field of tipping paper, and in particular to a embossed tipping paper. Background Art

[0002] After the tipping paper with embossing is prepared into a filter tip, it can increase the luxury feeling of cigarettes to a certain extent. However, in many cases, the three-dimensional sense of the embossing is not ideal and it is difficult to achieve the desired effect of the designer. Summary of the Invention

[0003] The purpose of the present invention is to provide an embossed tipping paper, which has the characteristics of more obvious concave-convex feeling and can increase the luxury feeling of cigarettes.

[0004] The technical solution adopted by the present invention is: an embossed tipping paper, including an upper layer and a lower layer both prepared from tipping base paper. A first concave area that is sunken downward is formed on the upper surface of the upper layer by embossing, and a first convex area is formed at a position corresponding to the first concave area on the lower surface of the upper layer. A second concave area that is sunken upward is formed on the lower surface of the lower layer by embossing, and a second convex area is formed at a position corresponding to the second concave area on the upper surface of the lower layer. At the same time, the first concave area and the second concave area are consistent, and the upper layer and the lower layer are adhered together, and the corresponding first convex area and the second convex area are adhered together.

[0005] An upper starch layer is filled at a position on the lower surface of the upper layer that is not the first convex area, and a lower starch layer is filled at a position on the upper surface of the lower layer that is not the second convex area, and the upper starch layer and the lower starch layer are adhered together.

[0006] The thickness of the upper starch layer is equal to the convex height of the first convex area, and the thickness of the lower starch layer is equal to the convex height of the second convex area.

[0007] The advantages of the present invention compared with the prior art are: the concave-convex feeling is more obvious and can increase the luxury feeling of cigarettes. The concave parts (i.e., the first concave area) of the upper layer and the concave parts (i.e., the second concave area) of the lower layer of the embossed tipping paper of the present invention correspond to each other in position and are adhered together, which is equivalent to forming concave parts with consistent positions both inside and outside the positions where the entire tipping paper has embossing, making the transparency at this place better, so that the formation of the concave-convex feeling on the surface of the filter tip not only lies in the existence of the concave area, but also the color of the internal acetate fiber and the like can be better transmitted, making the concave area also have an obvious change in color depth. That is, the concave-convex feeling is more obvious and three-dimensional, making the luxury feeling of cigarettes better. Brief Description of the Drawings

[0008] The present invention will be further described below with reference to the drawings and embodiments:

[0009] Figure 1It is the front sectional view of an embodiment of the present invention.

[0010] In the figure:

[0011] 10. Upper layer, 11. First concave area, 12. First convex area;

[0012] 20. Lower layer, 21. Second concave area, 22. Second convex area;

[0013] 31. Upper starch layer, 32. Lower starch layer. Detailed implementation mode

[0014] In the embodiment, as shown in Figure 1 The corrugated tipping paper includes an upper layer 10 and a lower layer 20 both made of tipping base paper. That is, when rolling the filter tip, it is bent downward so that the lower layer 20 contacts the filter material of the filter tip such as cellulose acetate.

[0015] Furthermore:

[0016] On the upper surface of the upper layer 10, a downward concave first concave area 11 is formed by embossing, and a first convex area 12 is formed at a position corresponding to the first concave area 11 on the lower surface of the upper layer 10. That is, for each part of the upper layer 10, its thickness is constant, so the area sunken downward on its upper surface and the corresponding position on the lower surface are convex downward. On the lower surface of the lower layer 20, an upward concave second concave area 21 is formed by embossing, and a second convex area 22 is formed at a position corresponding to the second concave area 21 on the upper surface of the lower layer 20. Similarly, the thickness of any part of the lower layer 20 is also constant, and the area sunken upward on its lower surface and the corresponding position on the upper surface are convex upward. At the same time, the first concave area 11 and the second concave area 21 are consistent. By consistent, it means that the positions of the first concave area 11 and the second concave area 21 correspond, and their lengths, widths, and thicknesses are the same. And, the upper layer 10 and the lower layer 20 are adhered together, and the first convex area 12 and the second convex area 22 are adhered together correspondingly. In this way, the three-dimensional sense of the concave area is stronger, and the change of color further increases the change of the concave area, adding a sense of luxury to the cigarette.

[0017] Optimally:

[0018] On the lower surface of the upper layer 10 at a position other than the first convex area 12, an upper starch layer 31 is filled, on the upper surface of the lower layer 20 at a position other than the second convex area 22, a lower starch layer 32 is filled, and the upper starch layer 31 and the lower starch layer 32 are adhered together. The positions of the non-first convex area 12 and the non-second convex area 22 refer to the positions on the upper layer 10 other than the first convex area 12 and the positions on the lower layer 20 other than the second convex area 22.

[0019] The thickness of the upper starch layer 31 is equal to the protruding height of the first protruding area 12, and the thickness of the lower starch layer 32 is equal to the protruding height of the second protruding area 22.

[0020] The upper starch layer 31 and the lower starch layer 32 are formed by the following method: after filling dry starch in the corresponding positions, gradually and slowly increase the humidity in the environment where the upper layer 10 and the lower layer 20 are located and maintain it for a period of time. Obviously, since both the upper starch layer 31 and the lower starch layer 32 are relatively thin, such as about 0.1 mm, it will not cause caking and hardness of the tipping paper.

[0021] In this way, the adhesion between the upper layer 10 and the lower layer 20 is relatively flat, and the overall effect of the filter tip is better.

[0022] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
