Description

Technical Field

[0001] The invention relates to the technical field of cigarette packaging boxes, in particular to inner packaging box paper for square cigarettes, a folding method thereof and a cigarette box containing the inner packaging box paper. Background Art

[0002] Currently, most cigarettes on the market are cylindrical in shape. With the development and progress of cigarette making technology, unconventional shapes of cigarettes have emerged, such as rectangular cigarettes (cigarettes with square cross-sections). If such special-shaped cigarette structures are produced using customized machinery and equipment, not only will the cost of cigarettes increase significantly, but the formed cigarettes will also be unable to be packaged, stored, transported, or sold in conventional cigarette boxes.

[0003] Since the cross-section of square cigarettes is different from that of regular cigarettes, if the existing packaging technology and regular cigarette packaging boxes are used to accommodate the square cigarettes after forming, it is easy to cause two problems:

[0004] First, it is extremely inconvenient to fill cigarettes, and the cigarettes cannot maintain their current shape after being formed. It is easy for the cigarettes in the box to be scattered and the slits to be uneven in size, which causes the cigarettes to shake and move during storage and transportation because they cannot be fixed in position, resulting in the cigarettes being squeezed and deformed and the tobacco shreds being scattered;

[0005] Second, it will also cause the gap inside the packaging box to be too large, thus causing the serious problem of the packaging box being deformed.

[0006] If customized cigarette packaging boxes are tailored for square cigarettes, the cost will be too high and it will not be conducive to the promotion and popularization of square cigarettes.

[0007] Therefore, how to change regular cigarette sticks into square cigarette sticks only through special packaging methods without mechanical processing, and conveniently fill them into cigarette packaging boxes (square cavities) of existing specifications, while meeting the packaging requirements of cigarette sticks, including stabilizing the position of cigarette sticks during transportation and storage to avoid deformation of cigarette sticks and facilitating access, etc. is what people hope.

[0008] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0054] 2. The present invention provides an inner packaging paper for square cigarettes. There is no need to add new cigarette production equipment or re-design the cigarette box structure, and the cost is low. Only through the newly designed inner packaging paper for square cigarettes and its folding method, the shape of the cigarettes can be changed, and the outer packaging requirements of the square cigarettes are met. The cigarette filling and pressing positioning sleeve and the middle spacer sleeve are both made of materials with good stiffness and strong support, making the cigarettes easy to store, stable in position during transportation, not prone to wrinkling and deformation due to mutual extrusion, and the cigarettes can be more stably formed through the stacking and extrusion of the packaging boxes and are not easy to change shape, avoiding the inconvenience in storage and transportation caused by putting the pre-prepared square cigarettes into the conventional cigarette packaging boxes in the prior art, and also avoiding separately preparing the square cigarette packaging boxes matching the square cigarettes. In addition, the bumps during transportation are more conducive to the transformation of the cigarette formation.

[0055] 2. The present invention provides consumers with a brand-new method of folding inner packaging box paper of square cigarettes, which satisfies the public's desire for novelty and curiosity about new things. The movable flip-up cigarette positioning partition sleeve structure optimizes the consumer's usage experience, facilitates the use of cigarettes, and can better cultivate consumers' trust and satisfaction with the brand. In the future, it can continue to focus on development for advertising and commercial promotion, realize the development of more products, functions and applications in the future, and achieve the purpose of development and promotion by continuously optimizing the experience.
