TECHNICAL FIELD

[0001] The present application relates to the technical field of special paper, in particular to a paperboard capable of emitting fragrance and a carton made of the paperboard. BACKGROUND

[0002] Ordinary paper has no fragrance.

[0003] In order to obtain paper capable of emitting fragrance, at present, a layer of incense powder or perfume is mainly sprayed on the surface of the paper, however, such fragrance is not easy to preserve, and will become weak or even completely lose fragrance due to long-term volatilization.

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0037] As follows Figure 1 The present application is described as follows:

[0038] Example 1: As follows Figure 2 A paperboard capable of emitting fragrance, comprising a paper layer 1, the paper layer 1 being coated with an ink layer 3; the printing ink of the ink layer 3 is made of the following percentage of raw materials: white ink 74.30%, black ink 12.38%, yellow ink 12.38%, red ink 0.15%, blue ink 0.31%, and plant essence 0.46%. The plant essence includes at least one of the following: jasmine water-soluble essence, osmanthus water-soluble essence, bergamot water-soluble essence, cologne water-soluble essence, green apple water-soluble essence, sweet orange water-soluble essence, Chanel water-soluble essence, Dior orange flower essence, ocean essence, Chanel essence, osmanthus essence, and Burberry essence.

[0039] The raw materials of the printing ink of the ink layer further include powders with porous structures, and the powders account for 3-5%, and the powders are one or more of highly dispersed silicon dioxide, zinc oxide, calcium carbonate, and talc powder.

[0040] The powders with porous structures can absorb and adsorb plant essence, and can prolong the emission time of fragrance. (The powders have developed void structures and have strong adsorption capacity, and can absorb the ink containing plant essence.)

[0041] As follows Figure 3 A paperboard structure, comprising an absorbing layer 2 connected with a paper layer 1, the paper layer 1 being provided with a plurality of through holes 11, an ink layer 3 being located between the absorbing layer 2 and the paper layer 1, a face paper layer 4 being connected with the absorbing layer 2 and the paper layer 1, the paper layer 1 and the absorbing layer 2 being located between the two face paper layers 4, the face paper layer 4 being fixedly connected with the absorbing layer 2 through glue, and the face paper layer 4 being fixedly connected with the absorbing layer 2 through the through holes 11. The absorbing layer 2 is arranged in a wave shape to form a wave-shaped structure capable of absorbing and storing fragrance, the absorbing layer 2 can absorb and store fragrance, the absorbing layer 2 is made of water-absorbing cotton paper, or the absorbing layer 2 is provided with a water-absorbing cotton paper layer. The paperboard structure is a corrugated paperboard, which is equivalent to adding the paper layer 1 with the ink layer 3 capable of emitting fragrance to the existing corrugated paperboard, so that the fragrance can only be emitted along the edges of the paperboard, prolonging the emission time and the effective time of the fragrance.

[0042] As follows Figures 4-6 Another embodiment of the absorbing layer 2, the absorbing layer 2 being a honeycomb paper structure.

[0043] In order to improve the absorption of the flavor by the absorption layer 2, a volatile substance can be added to the printing ink. After the printing ink is prepared, the paper layer is coated with the ink layer by using a coating roller. The lower end of the coating roller is provided with an ink tank, and a part of the lower end of the coating roller is immersed in the ink in the ink tank. The coating roller rotates, and the ink is attached to the coating roller. The volatile substance is sprayed onto the coating roller (the spraying of the volatile substance onto the coating roller is continuously performed during the coating operation of the coating roller), and then the paper layer is coated again. In this way, the ink with the volatile substance is coated on the paper layer. The paper layer is then combined with the absorption layer 2 and then combined with the face paper layer to form a corrugated paperboard structure.

[0044] Alternatively, the volatile substance is sprayed on the ink layer 3. After the printing ink is prepared, the paper layer is coated with the ink layer by using a coating roller. Then, the volatile substance is sprayed on the ink layer on the paper layer. The volatile substance is preferentially sprayed on the ink layer 3 that has not yet dried. The paper layer is then combined with the absorption layer 2 and then combined with the face paper layer to form a corrugated paperboard structure.

[0045] The volatile substance has a stronger volatilization ability, which promotes the better escape of the flavor in the ink layer 3 to the absorption layer 2 and covers the absorption layer 2, so that the absorption layer 2 also has a flavor. The volatile substance can be ethanol, n-hexane, etc.

[0046] In the production process of the paperboard, after the ink layer 3 is coated on the paper layer 1, the ink layer 3 is immediately sprayed with a misty volatile substance. At the same time, the paper layer 1 is immediately combined with the absorption layer 2 and the face paper layer to form a corrugated paperboard structure. In this way, a surrounding structure that can only emit from the edge of the paperboard is formed, which locks the flavor and can prolong the emission time of the flavor.

[0047] Reference Figure 7When the paperboard is used for a long time or placed for a long time, the paperboard cannot supplement the fragrance after the fragrance is exhausted or the fragrance is not strong enough. Therefore, the technical scheme is provided in the application to supplement the fragrance. The technical scheme is that a fragrance adding strip 5 is arranged between the surface paper layer 4 and the absorption layer 2. The fragrance adding strip 5 is in a long strip shape. The fragrance adding strip 5 is composed of two layers of films 51. A main channel 52 is formed between the two layers of films 51. The main channel 52 extends along the length direction of the fragrance adding strip 5. The main channel 52 penetrates through both ends of the length direction of the fragrance adding strip 5. A branch channel 53 is formed between the two layers of films 51. The branch channel 53 extends along the width direction of the fragrance adding strip 5. The branch channel 53 is arranged on both sides of the main channel 52. The branch channel 53 is in communication with the main channel 52. There are a plurality of branch channels 53. The plurality of branch channels 53 are arranged at intervals in the length direction of the fragrance adding strip 5. The width of the branch channel 53 is 0.5-2 mm. The width of the main channel 52 is 5-10 mm. After the paperboard is cut into a paperboard with a required size, the end of the cut-off fragrance adding strip 5 is also exposed on the edge of the paperboard. Liquid plant essence can be injected into the main channel 52 by using an injection device. The plant essence enters the main channel 52 and flows along the main channel 52 under the action of the injection pressure and flows out through the branch channel 53 and enters the absorption layer 2. Thus, the paperboard is supplemented with fragrance.

[0048] Reference ​ A groove 41 (the groove is a pressure mark) is arranged on the inner side of the surface paper layer 4 connected with the absorption layer 2. The groove 41 is arranged in correspondence with the main channel 52. Part or all of the main channel 52 is located in the groove 41. The groove 41 forms a space for conveniently injecting the liquid plant essence.

[0049] A paper box is made of the paperboard capable of emitting fragrance.

[0050] The above only describes the preferred embodiments of the application and is not used to limit the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
