An inner packaging paper for triangular cigarette sticks, its folding method, and a cigarette case containing the same

Abstract

The present invention provides an inner packaging paper for triangular cigarette sticks, a folding method thereof, and a cigarette case including the same. The packaging paper wraps a first inner cavity partition (1) and a second inner cavity partition (2). The present invention designs the first inner cavity partition (1) and the second inner cavity partition (2) with specific shapes. By means of a folding method, conventional round cigarette sticks are placed into a cigarette case made of the inner packaging paper that can be folded into a triangular cigarette stick. The cigarette sticks are restricted in a cavity with a specific shape and size, which has a fixing and squeezing effect on the cigarette sticks, so that the conventional round cigarette sticks are changed into cigarette sticks with a triangular cross-section and can be loaded into an existing specification packaging box (square cavity) without the need to re-design the box type structure, avoiding the problems of excessively high costs and cumbersome steps caused by directly producing triangular cigarette sticks through mechanical equipment in the prior art. At the same time, it also avoids separately preparing a triangular cigarette stick packaging box that matches the triangular cigarette sticks.

Description

Technical Field

[0001] The invention relates to the technical field of cigarette packaging boxes, and in particular to an inner packaging box paper for triangular 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, cigarettes with unconventional shapes have emerged, such as cigarettes with triangular 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 triangular 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 conventional cigarettes into triangular cigarettes by special packaging methods without mechanical processing, and conveniently load 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 of cigarettes and facilitate access, etc. is what people hope.

[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 triangular cigarettes, a folding method thereof and a cigarette box containing the same. An inner packaging box paper for triangular cigarettes is designed without mechanical processing, and conventional cigarettes are changed into triangular cigarettes through a special packaging method, so as to solve the technical problems existing when the existing packaging technology and conventional cigarette packaging boxes are used to accommodate the formed triangular cigarettes.

[0010] In order to solve the above technical problems, the specific technical solutions of the present invention are as follows:

[0011] In the first aspect of the present invention, an inner packaging paper for a triangular cigarette is provided. The packaging paper includes a first inner cavity partition 1 and a second inner cavity partition 2;

[0012] A plurality of parallel crease lines are preset on the first inner cavity partition 1. Along the crease lines, it can be folded into a first triangular protrusion 11 and a first triangular groove 12 with a triangular cross-section connected in sequence. The first triangular protrusion 11 and the first triangular groove 12 are the same in size and shape;

[0013] A plurality of parallel crease lines are preset on the second inner cavity partition 2. Along the crease lines, it can be folded into a second triangular protrusion 21 and a second triangular groove 22 with a triangular cross-section connected in sequence. The second triangular protrusion 21 and the second triangular groove 22 are the same in size and shape, and a vertical partition 23 is provided in the second triangular groove 22;

[0014] After folding, the first inner cavity partition 1 and the second inner cavity partition 2 are stacked face to face and opposite to each other. The first triangular protrusion 11 of the upper first inner cavity partition 1 is opposite to the second triangular groove 22 of the lower second inner cavity partition 2, and a plurality of cigarette accommodating cavities with a rhombus cross-section connected in sequence can be formed. The vertical partitions 23 in the second triangular grooves 22 are respectively connected to the triangular vertices of the upper first triangular protrusion 11 and the triangular vertices of the lower second triangular grooves 22, and the rhombus cigarette accommodating cavities are divided into middle-layer triangular accommodating cavities on both sides of the vertical partitions 23;

[0015] The first triangular groove 12 is the upper-layer triangular accommodating cavity, and the second triangular protrusion 21 is the lower-layer triangular accommodating cavity; the upper-layer, middle-layer, and lower-layer triangular accommodating cavities play a role in fixing and squeezing the cigarette, making the cross-section of the round cigarette become triangular and accommodating it therein. In order to achieve the effect of squeezing the cigarette, the diameter of the inscribed circle of the cavity for accommodating an independent cigarette is smaller than the diameter of the cigarette. That is to say, the diameter of the inscribed circle of the upper-layer, middle-layer, and lower-layer triangular accommodating cavities is smaller than the diameter of the cigarette.

[0016] Preferably, the point where the first triangular groove 12 and the second triangular protrusion 21 are connected is the vertex of the upper triangle and the lower triangle. The middle-layer triangular accommodating cavities on both sides of this vertex and the upper-layer and lower-layer triangular accommodating cavities above and below this vertex together form a square; the two sides of the first triangular groove 12 are the upper diagonal parts of this square, the two sides of the second triangular protrusion 21 are the lower diagonal parts of this square, and the two vertical partitions 23 on the left and right are the two sides of this square; this vertex is the intersection point of the diagonals of the square.

[0017] Preferably, the height of the triangular accommodating cavities in the upper layer, middle layer, and lower layer is equal to half of the base of the triangle.

[0018] Preferably, there are 5 triangular accommodating cavities in the upper layer, 5 triangular accommodating cavities in the lower layer, and 10 triangular accommodating cavities in the middle layer.

[0019] Preferably, the materials of the first inner cavity partition 1 and the second inner cavity partition 2 are cardboard or food-grade PVC sheets.

[0020] The material of the inner cavity partition 1 is preferably a material with good stiffness and strong support, such as cardboard, food-grade PVC sheets, etc.

[0021] The second aspect of the present invention provides a folding method for the inner packaging paper of a triangular cigarette. Using the inner packaging paper described in the first aspect of the present invention, the method includes the following steps:

[0022] a. A plurality of parallel crease lines are preset on the first inner cavity partition 1. Folding along the crease lines can form a first triangular protrusion 11 and a first triangular groove 12 with a triangular cross-section that are connected in sequence.

[0023] b. A plurality of parallel crease lines are preset on the second inner cavity partition 2. Folding along the crease lines can form a second triangular protrusion 21 and a second triangular groove 22 with a triangular cross-section that are connected in sequence. A vertical partition 23 is provided in the second triangular groove 22.

[0024] c. The folded first inner cavity partition 1 and the second inner cavity partition 2 are stacked face to face and opposite. The first triangular protrusion 11 of the first inner cavity partition 1 in the upper layer is opposite to the second triangular groove 22 of the second inner cavity partition 2 in the lower layer, and several cigarette accommodating cavities with a rhombus cross-section that are connected in sequence can be formed. The vertical partitions 23 in the second triangular grooves 22 are respectively connected to the triangular vertices of the first triangular protrusion 11 in the upper layer and the triangular vertices of the second triangular groove 22 in the lower layer, and the rhombus-shaped cigarette accommodating cavities are divided into middle triangular accommodating cavities on both sides of the vertical partition 23.

[0025] Preferably, the distances between the multiple longitudinal crease lines on the first inner cavity partition 1 and the second inner cavity partition 2 are equal, and this distance is √2 / 2 times the height of the partition 23.

[0026] The third aspect of the present invention provides a cigarette case, which includes the inner packaging paper described in the first aspect of the present invention. The cigarette case further includes a case body 3. The inner packaging paper formed by folding the inner packaging paper is located in the case body 3. The cigarette accommodating cavities play a role in fixing and squeezing the cigarettes, making the round cigarettes become triangular and accommodating them therein.

[0027] The cigarette case is a conventional flip-top handmade cigarette packaging box.

[0028] The method for manufacturing the inner cavity partition of the present invention is as follows:

[0029] 1. According to requirements, determine the specifications of the cigarettes to be manufactured and the style of the selected packaging box, and determine the structural dimensions of the inner cavity partition to ensure that the dimensions of each component match the selected cigarette packaging box;

[0030] 2. Draw the structural drawings of the inner cavity partition, and use a cutting and punching machine in cooperation with manual work to cut and mold the selected materials, such as cardboard, food-grade PVC sheets, etc., to produce the required style.

[0031] Solve the problem of batch processing of the inner cavity partition by printing and die-cutting methods.

[0032] Load the regular round cigarettes in large production into the formed inner cavity partitions according to the previously determined arrangement method, and place them in the packaging box. Through the pressure during the forming process of the packaging box, make them into the shape of the special-shaped cigarettes to be manufactured. Form and conduct multi-batch tests and use.

[0033] The present invention has the following advantages compared with the prior art:

[0034] 1. The present invention provides an inner packaging paper for triangular cigarettes. By designing and cutting the packaging paper, the first inner cavity partition 1 and the second inner cavity partition 2 of the cigarettes with a specific shape are designed. By folding, the regular round cigarettes are placed into the cigarette case made of the inner packaging paper that can be folded into a triangular cigarette, restricting the cigarettes in a cavity with a specific shape and size, exerting a fixing and squeezing effect on the cigarettes, changing the regular round cigarettes into cigarettes with a triangular cross-section, and being able to be loaded into the square cavity of the existing specification packaging box without re-designing the box type structure, avoiding the problems of excessively high cost and cumbersome steps caused by directly producing triangular cigarettes through mechanical equipment in the prior art.

[0035] 2. The present invention provides an inner packaging paper for triangular cigarettes. Without the need to newly add cigarette production equipment or re - design the cigarette box structure, it has low cost. By only using a newly designed inner packaging paper for triangular cigarettes and its folding method, the shape of the cigarettes can be changed, and the outer packaging requirements for cigarettes with a triangular cross - section are met. Both the first inner cavity partition 1 and the second inner cavity partition 2 are made of materials with good stiffness and strong support, making the cigarettes convenient for storage, stable in position during transportation, not prone to wrinkling and deformation due to mutual extrusion, and enabling the cigarettes to be more stable in shape through the stacking and extrusion of the packaging boxes, not easily changing shape, avoiding the inconveniences in storage and transportation caused by putting pre - prepared triangular cigarettes into conventional cigarette packaging boxes in the prior art, and also avoiding separately preparing triangular cigarette packaging boxes that match the triangular cigarettes. In addition, the jolts during transportation are more conducive to the transformation of the cigarette formation.

[0036] 3. The present invention provides consumers with a brand - new folding method for the inner packaging paper of triangular cigarettes, meeting the public's psychology of being curious about new things. By means of the structure of the movable and turn - up cigarette positioning partition sleeve, the use experience of consumers is optimized, making it convenient to pick up cigarettes, and better cultivating consumers' trust and satisfaction in the brand. Subsequently, it can continue to be focused on developing for advertising and commercial promotion; realizing the development of more subsequent products, functions, and applications, and achieving the purpose of development and promotion through continuous optimization of the experience.
