Description

Technical Field

[0001] The present invention relates to the technical field of cigarette packaging boxes, and in particular to an inner packaging box paper for cigarettes of a square and round combination type, 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 advancement of cigarette-making technology, unconventional shapes have emerged, such as those with a circular cross-section at one end and a square cross-section at the other. If these combined square and round shapes were produced using customized machinery, not only would the cost of the cigarettes increase significantly, but the finished cigarettes would also be difficult to package, store, transport, or sell in conventional cigarette boxes.

[0003] Because the cross-section of irregular-shaped cigarettes is different from that of regular cigarettes, using existing packaging technology and conventional cigarette packaging boxes to accommodate irregular-shaped cigarettes after molding can easily cause two problems:

[0004] First, it is extremely inconvenient to fill cigarettes, and the cigarettes cannot maintain their original shape after being formed. The cigarettes in the box are easily scattered and the slits are uneven in size. As a result, the cigarettes cannot be fixed in place during storage and transportation, causing them to shake and move, resulting in the cigarettes being squeezed and deformed, and the tobacco being scattered;

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

[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, people hope to transform conventional cigarettes into square and round cigarettes through special packaging methods without mechanical processing, and to conveniently fill them into the square cavity of existing cigarette packaging boxes, while meeting the packaging requirements of cigarettes, including stabilizing the position of cigarettes during transportation and storage to avoid deformation and facilitate access.

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

[0009] The purpose of the present invention is to provide an inner packaging box paper for cigarettes that combines square and round shapes, a folding method thereof, and a cigarette box containing the same.

Fold the seventh side panel 34 along the second isosceles trapezoidal crease line to form a trapezoidal protrusion 341, and fold the fifth side panel 32 toward the sixth side panel 33 through the fourth side panel 31. The fifth side panel 32 and the sixth side panel 33 are relatively parallel to each other, forming two right-angled grooves, with the trapezoidal protrusion 341 located between the two right-angled grooves;

[0035] The cigarette filling and pressing positioning sleeve 1 is folded into a first cuboid:

[0036] c. Fold the second folding baffle 12, the third folding baffle 13, the fourth folding baffle 14, and the sixth folding baffle 16 of the cigarette loading and pressing sleeve 1 inward along the edges adjacent to the first folding baffle 11, so that the second folding baffle 12 and the third folding baffle 13 are relatively parallel, and the fourth folding baffle 14 is perpendicular to the first folding baffle 11;

[0037] d. Fold the fifth folding baffle 15 toward the first folding baffle 11 along the edge adjacent to the fourth folding baffle 14 so that the fifth folding baffle 15 is relatively parallel to the first folding baffle 11;

[0038] e. Fold the first folding ear 17 along the edges adjacent to the second folding baffle 12 and the third folding baffle 13 so that the first pin 171 of the first folding ear 17 is inserted into the first pre-cut 151 corresponding to the fifth folding baffle 15;

[0039] f. Fold the second folding ear 18 and the third folding ear 19 at the top of the sixth folding baffle 16 and insert them into the cigarette filling and pressing positioning sleeve 1 from the top surface of the first cuboid;

[0040] A partition 4 is provided, which does not need to be folded.

[0041] A third aspect of the present invention provides a cigarette box, comprising the inner packaging paper according to the first aspect of the present invention, the cigarette box further comprising a box body 6, the middle-layer fixing sleeve 3 being located within the inner cavity fixing sleeve 2, the inner cavity fixing sleeve 2 being located within the cigarette filling, pressing and positioning sleeve 1, and the cigarette filling, pressing and positioning sleeve 1 being located within the box body 6;

[0042] The box body 6 has a cigarette accommodating cavity;

[0043] The cigarette accommodating chamber is divided into three layers: upper, middle, and lower. The right-angled groove formed by folding the middle-layer fixing sleeve 3 is inserted into the trapezoidal groove formed by folding the inner-cavity fixing sleeve 2. The first rectangular parallelepiped wraps the trapezoidal groove to form three layers: upper, middle, and lower. The right-angled groove is the middle layer. Each layer of cigarettes is provided with an independent partition 4.

[0044] The round cigarette in the trapezoidal groove 5 is fixed and squeezed by the cigarette filling and pressing positioning sleeve 1, the inner cavity fixing sleeve 2, the middle layer fixing sleeve 3 and the partition 4, so that the round cigarette is transformed into a square and round combination cigarette.

[0046] In order to ensure that only one end of the cigarette is square, in the present invention, the length of the middle fixing sleeve 3 and the partition 4 is only half of the axial length of the cigarette.

[0047] The manufacturing method of the middle layer fixing sleeve of the present invention is as follows:

[0048] 1. According to the needs, determine the specifications of the cigarettes to be produced and the style of the selected packaging box, determine the structural dimensions of the middle-layer fixed sleeve, and ensure that the dimensions of each component match the selected cigarette packaging box;

[0049] 2. Draw the structural drawings of the middle-layer fixed sleeve, and use a cutting and proofing machine to manually cut and mold the preferred materials, such as cardboard, food-grade PVC sheets, etc., to produce the required style.

[0050] Printing and die-cutting methods are used to solve the problem of batch processing of middle-layer fixed sleeves.

[0051] Regular, round cigarettes from mass production are placed into the pre-determined middle compartments and placed into packaging. Pressure during the packaging process transforms them into the desired square and round combination cigarette shape. This process is followed by multiple batches of testing and use.

[0052] The present invention has the following advantages over the prior art:

[0053] 1. The present invention provides an inner packaging box paper for combined square and round cigarettes. By designing and cutting the packaging box paper, a cigarette filling and pressing positioning sleeve and a middle-layer fixing sleeve with specific shapes are designed. Conventional round cigarettes are placed in a cigarette box made of the inner packaging box paper for combined square and round cigarettes by folding, and the cigarettes are confined in a cavity of specific shape and size, which has a fixing and squeezing effect on the cigarettes, so that the conventional round cigarettes are changed into combined square and round cigarettes, and can be loaded into packaging boxes of existing specifications (square cavities) without redesigning the box structure, thereby avoiding the problems of high cost and cumbersome steps caused by directly producing combined square and round cigarettes through mechanized equipment in the existing technology.

[0054] 2. The present invention provides an inner packaging box paper for square and round combination cigarettes. It does not require new cigarette production equipment or a redesign of the cigarette box structure, and is low-cost. The shape of the cigarettes can be changed by simply using the newly designed inner packaging box paper for square and round combination cigarettes and its folding method. It also meets the outer packaging requirements of square and round combination cigarettes. The cigarette filling and pressing positioning sleeve and the middle layer fixing sleeve are both made of materials with good stiffness and strong support, making the cigarettes easy to store and stable in position during transportation. They will not be wrinkled or deformed due to mutual squeezing. The stacking and squeezing of the packaging box can make the cigarettes more stable and less likely to change shape. This avoids the storage and transportation inconvenience caused by placing pre-prepared square and round combination cigarettes into conventional cigarette packaging boxes in the prior art, and also avoids the need to separately prepare square and round combination cigarette packaging boxes that match the square and round combination cigarettes. In addition, the bumps during transportation are more conducive to the transformation of the cigarette shape.

[0055] 3. The present invention provides consumers with a new method of folding the inner packaging box paper of a combination of square and round 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.

[0056] 4. The square and round combination cigarette of the present invention is novel in form, with a circular cross section at one end and a square cross section at the other end, which perfectly expresses the beautiful meaning of the round sky and square earth, and is more attractive to consumers.

[0074] The inner cavity fixing sleeve 2 includes a first side panel 21, with the left and right sides of the first side panel 21 respectively connected to the second side panel 22, and the end of the second side panel 22 away from the first side panel 21 is connected to the third side panel 23, and the third side panel 23 has side wings 231 on the upper and lower sides;

[0075] The second side panel 22 and the third side panel 23 are folded toward the first side panel 21, and the side wing 231 is folded toward the second side panel 22 to form a trapezoidal groove 5. The first side panel 21 is the surface where the upper base of the trapezoidal groove 5 is located, and the third side panel 23 is the surface where the waist of the trapezoidal groove 5 is located. The second side panel 22 is perpendicular to the first side panel 21 and is located on the outside of the third side panel 23. The second side panel 22, the third side panel 23, and the side wing 231 are folded to form a triangular prism 51. The bottom surface of the triangular prism 51 is located on the first side panel 21, thereby defining the surface where the upper base of the trapezoidal groove 5 is located.
