Description

Cigarette package capable of repeatedly sealing window and method Technical Field The invention belongs to the technical field of cigarette packaging, and particularly relates to a cigarette packaging with a repeatable sealing window and a method thereof. Background In order to improve the attractive appearance and the display effect of the product, various cigarette packaging boxes with transparent windows appear on the market. The consumer can see the cigarette products inside through the window without opening the box, which increases the desire to purchase and the identity of the products. However, this type of design has a significant technical disadvantage in that once the package is first opened, the liner paper is typically removed or destroyed completely, resulting in the window area on the case being exposed therefrom. After the packaging box is closed, pollutants such as outside air, moisture, dust and the like can easily enter the box through the window, so that cigarettes are affected with damp, dry or polluted, and the smoking quality and the shelf life of the cigarettes are seriously affected. In other words, there is an irreconcilable contradiction between the "display function" and the "sealed preservation function of the package" of the existing cigarette box with a window. Therefore, an innovative packaging scheme is needed to effectively solve the problem of sealing failure caused by the window while retaining the display advantages of the window. Disclosure of Invention The invention provides a cigarette package capable of repeatedly sealing a window and a method thereof. The invention adopts the following technical scheme to achieve the aim: The utility model provides a cigarette package of repeatedly sealing window, includes the box body be provided with the lid that can open and shut on the box body be provided with interior slip sheet in the box body set up the window that is used for observing the cigarette on the lid be in prefabricated the tear line on the interior slip sheet, the tear line will interior slip sheet is divided into separable open area and the sealed area of permanently keeping in the box body, the position of sealed area corresponds with the position of window to cover and seal the window when the lid is closed. Further, a pull tab is fixedly disposed on the opening area. Still further, the tearing line is a U-shaped line, a V-shaped line, a C-shaped line, a straight line or a closed or non-closed graph line formed by combining the above lines, and the tearing line is a broken line, a point broken line, an indentation line or a laser scribing line. Furthermore, the sealing area is made of transparent or semitransparent materials, and the area of the sealing area is larger than or equal to that of the window. Further, the sealing area is fixed on the inner wall of the box body in an adhesive mode. Furthermore, the material of the sealing area is a composite film material with the function of moisture resistance and oxygen resistance. A method of cigarette packaging with a resealable window comprising the steps of: s1, preparing lining paper; S2, placing the lining paper into the box body in a preset direction and at a preset position, so that a sealing area of the lining paper corresponds to the position of a window on the box cover; S3, filling the cigarette group into the box body and wrapping the cigarette group by the lining paper; s4, closing the box cover to finish packaging, and taking out the opening area through the tearing line when a consumer opens for the first time, wherein the sealing area is reserved in the box body and is used for sealing the window when the subsequent box cover is closed. Further, the preparation of the S1 lining paper specifically comprises the following steps: S11, taking lining paper base material; And S12, forming the tearing line on the preset position of the lining paper base material through die cutting, laser engraving or printing process, wherein the tearing line separates the base material into a corresponding opening area and a sealing area. Still further, before or after the lining paper is put in, an adhesive is coated at a position corresponding to the inner wall of the box body in the sealing area, so that the sealing area is fixed in the box body. Compared with the prior art, the invention has the following advantages: the invention realizes the unification of 'display' and 'seal', and fundamentally solves the technical contradiction in the industry. After the cigarette case is opened for the first time, the cigarette case can still realize effective sealing through the reserved lining paper sealing area, and the preservation quality of cigarettes is greatly improved. The actions of opening the box and taking cigarettes are completely consistent with the traditional package, and no extra learning or operation steps are needed. The sealing can be automatically completed by closing the box cover, so that the box is co
