The back side of the sticker 3 is fixedly attached to the back sealing area of the inner package 2, the front side of the sticker 3 is fixedly attached to the inner side of the front wall of the upper box cover 12, the inner surface of the sticker 3 can cover the opening 21 of the inner package 2 when the upper box cover 12 is closed on the lower box body 11, the areas of the inner surface of the sticker 3 corresponding to the opening 21, the front sealing area 22, the left sealing area 23, the right sealing area 24 and the back sealing area are respectively a first area 31, a second area 32, a third area 33, a fourth area 34 and a fifth area 35, the second area 32, the third area 33, the fourth area 34 and the fifth area 35 are respectively located at the front side, the left side, the right side and the rear side of the periphery of the first area 31, the first adhesive coating 5 capable of being repeatedly attached is arranged on the second area 32, the third area 33 and the fourth area 34 and is respectively used for attaching the front sealing area 22, the left sealing area 23 and the right sealing area 24, the first adhesive coating 5 is arranged around the periphery of the opening 21 in a U-shape with its width direction being the direction along which the inner and outer sides extend, see fig. 4. A permanently affixed second adhesive coating 8 is provided on the fifth area 35 and the rear edge of the sticker 3 is affixed to the rear seal area by the second adhesive coating 8 on the fifth area 35.

In the present invention, the first adhesive coating 5 of the second region 32 is further provided with a viscosity reducing coating 6, the viscosity reducing coating 6 is made of a viscosity reducing material dispersed on the first adhesive coating 5, the viscosity reducing material forms a discontinuous surface on the adhesive coating, and the viscosity reducing material has no viscosity or the viscosity between the viscosity reducing material and the inner package 2 is smaller than the viscosity between the first adhesive coating 5 and the inner package 2.

In order to avoid the problem that consumers are hard to open the package for the first time, the adhesive force of the first adhesive coating 5 between the sticker 4 and the inner package 2 is generally reduced, and the adhesive force of the adhesive itself is reduced, or the width (in the inside and outside directions) of the first adhesive coating 5 is reduced, however, by analyzing the present invention of the existing package, since the function of the cigarette package is to maintain the moisture and fragrance of the internal consumer goods, the material adopted by the inner package 2 and the sticker 3 is preferably a novel airtight composite material, the requirement for the adhesive coated on the sticker 3 is very high, three conditions need to be satisfied, the first one is suitable for the novel composite material, the second one is capable of having a stable adhesive effect at higher and lower temperatures, the third one is capable of having a suitable adhesive property, and the third one is capable of being easily peeled, yet still be sufficiently tacky to allow repeated peeling. Therefore, in the implementation and use, the selection of the adhesive is very difficult, and only a few parts can meet the use requirements, so that the better adhesive with low viscosity is difficult to realize. In addition, since the sticker 3 needs to be opened and adhered repeatedly many times, dust or cut tobacco fragments fall onto the first adhesive coating 5, and thus if the width thereof is reduced, adhesive force is reduced for a long time use, and when the sealing area of the first adhesive coating 5 is narrowed, a passage for air circulation is easily generated in the sealing area, resulting in poor sealing effect, and therefore, it is difficult to solve the problem well by reducing the width of the first adhesive coating 5.

The principle of the packing box related by the invention is as follows: before the first opening, the upper cover 12 of the outer box 1 is closed on the upper end of the lower box 11, the inner surface of the sticker 3 covers the opening 21 of the inner package 2, and the second area 32, the third area 33 and the fourth area 34 are tightly adhered to the front sealing area 22, the left sealing area 23 and the right sealing area 24 around the opening 21 of the inner package 2 through the first adhesive coating 5, so that the opening 21 can be sealed and the consumer goods in the inner package 2 can be protected. The second area 32 of the inner surface of the sticker 3 can effectively reduce the adhesive force between the second area 32 and the front sealing area 22 of the inner package 2 by providing the anti-adhesive coating 6 on the first adhesive coating 5 and using an anti-adhesive material having no or small adhesive force, when the upper lid 12 of the package box is opened for the first time, the upper lid 12 will drive the second area 32 to be separated from the front sealing area 22, and the adhesive force at the position is the main opening resistance, so that the required force when the package box is opened for the first time can be effectively reduced, the width of the first adhesive coating 5 on the second area 32 in the inner side direction does not need to be reduced, that is, the area of the first adhesive coating 5 is not reduced, and thus the sealing effect can be ensured. In addition, due to the fact that various requirements on the adhesive in the prior art result in less selection of the adhesive in the first adhesive coating 5, the adhesive which meets other conditions and has stronger viscosity can be also suitable for the first adhesive coating 5 in the invention by adopting the mode of the invention, the selection range of the adhesive is increased, and the manufacture of the packaging box is facilitated. When the package is closed again, the inner surface of the sticker 3 covers the opening 21 of the inner package 2 again, and the second, third and

fourth areas

32, 33, 34 are repeatedly attached to the front, left and right sealing

regions

22, 23, 24 by the first adhesive coating 5 to seal the opening 21 again, so that the package can be sealed repeatedly. The packing box capable of being sealed repeatedly, provided by the invention, has the advantages that the sealing performance of the adhesive label 3 and the inner packing 2 is ensured, the force required by opening the packing box is effectively reduced, the structure is simple, and the use and the manufacture are convenient.
