An inner packaging paper for a hexagonal cigarette rod, its folding method, and a cigarette case including the same

Abstract

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

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 hexagonal 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 hexagonal 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 hexagonal 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 hexagonal cigarettes without mechanical processing and only through special packaging methods, and 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 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 hexagonal cigarettes, a folding method thereof and a cigarette box containing the same. An inner packaging box paper for hexagonal cigarettes is designed without mechanical processing, and conventional cigarettes are changed into hexagonal cigarettes through a special packaging method to solve the technical problems existing when the existing packaging technology and conventional cigarette packaging boxes are used to accommodate the formed hexagonal 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 hexagonal cigarettes is provided. The packaging paper includes at least two layers of inner cavity partitions 1. Crease lines 13 are preset on the inner cavity partitions 1. By folding along the crease lines 13, trapezoidal protrusions 11 and trapezoidal grooves 12 with trapezoidal cross-sections connected in sequence can be folded. The trapezoidal protrusions 11 and the trapezoidal grooves 12 are the same in size and shape. Stacking the two folded inner cavity partitions 1 face to face and opposite, with the trapezoidal protrusions 11 of the upper inner cavity partition 1 facing the trapezoidal grooves 12 of the lower inner cavity partition 1, a number of cigarette receiving cavities with hexagonal cross-sections connected in sequence can be formed. The cigarette receiving cavities fix and squeeze the cigarettes, causing the cross-section of the cigarettes to become hexagonal and be accommodated therein. In order to achieve the effect of squeezing the cigarettes, the diameter of the inscribed circle of the cavity for accommodating a single cigarette is smaller than the diameter of the cigarette, that is to say, the diameter of the inscribed circle of the cigarette receiving cavity with a hexagonal cross-section is smaller than the diameter of the cigarette.

[0012] Preferably, the upper sides and the two waists of the trapezoidal protrusions 11 and the trapezoidal grooves 12 are equal, and a number of cigarette receiving cavities with regular hexagonal cross-sections connected in sequence can be formed.

[0013] Preferably, the head and tail of the trapezoidal protrusions 11 and the trapezoidal grooves 12 are connected in sequence.

[0014] Preferably, the number of the regular hexagons is seven.

[0015] Preferably, the material of the inner cavity partition 1 is cardboard or food-grade PVC sheet.

[0016] The material of the inner cavity partition 1 is preferably a material with good stiffness and strong support, such as cardboard, food-grade PVC sheet, etc.

[0017] In the second aspect of the present invention, a folding method for the inner packaging paper described in the first aspect of the present invention is provided. The method includes the following steps:

[0018] a. There are multiple longitudinal crease lines 13 on the inner cavity partition 1. The inner cavity partition 1 is repeatedly folded along the crease lines 13 to fold out trapezoidal protrusions 11 and trapezoidal grooves 12 with trapezoidal cross-sections connected in sequence.

[0019] b. Stack the folded inner cavity partitions 1 face to face and opposite, with the trapezoidal protrusions 11 of the upper inner cavity partition 1 facing the trapezoidal grooves 12 of the lower inner cavity partition 1, to form a number of cigarette receiving cavities with hexagonal cross-sections connected in sequence.

[0020] Preferably, the distances between the multiple longitudinal crease lines 13 on the inner cavity partition 1 are equal, such that the upper sides and two waists of the trapezoidal protrusions 11 and trapezoidal grooves 12 formed by folding are equal, and a plurality of cigarette accommodating cavities with a regular hexagon cross-section connected in sequence can be formed.

[0021] 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 2, and the inner packaging paper formed by folding the inner packaging paper is located in the case body 2. The cigarette accommodating cavity has a fixing and squeezing effect on the cigarettes, making the cigarettes become hexagonal and be accommodated therein.

[0022] The cigarette case is a conventional flip-top handmade cigarette packaging case.

[0023] Preferably, the inner cavity partition 1 is in 4 layers. By stacking the 4 layers of the folded inner cavity partition 1 face to face, three layers of the cigarette accommodating cavities, namely upper, middle, and lower layers, can be formed.

[0024] Preferably, the upper and lower layer cigarette accommodating cavities include 7 hexagon-shaped cavities connected in sequence, and the middle layer cigarette accommodating cavity includes 6 hexagon-shaped cavities connected in sequence.

[0025] The manufacturing method of the inner cavity partition of the present invention is as follows:

[0026] 1. According to requirements, determine the specifications of the cigarettes to be manufactured and the style of the selected packaging case, and determine the structural dimensions of the inner cavity partition to ensure that the dimensions of each component match the selected cigarette packaging case.

[0027] 2. Draw the structural drawings of the inner cavity partition, and use a cutting and die-cutting machine in cooperation with manual work to cut and mold the selected materials, such as cardboard, food-grade PVC sheets, etc., to make the required style.

[0028] Solve the problem of batch processing of the inner cavity partition by printing and die-cutting methods.

[0029] Load the conventional round cigarettes in large production into the formed inner cavity partitions according to the previously determined arrangement method, and put them into the packaging case. Through the pressure during the forming process of the packaging case, make them into the shape of the special-shaped cigarettes to be manufactured. Form and conduct multiple batches of tests and use.

[0030] The present invention has the following advantages over the prior art:

[0031] 1. The present invention provides an inner packaging paper for hexagonal cigarettes. By designing and cutting the packaging paper, an inner cavity partition with a specific shape is designed. Through the method of folding, conventional round cigarettes are placed into a cigarette case made of the inner packaging paper that can be folded into a hexagonal cigarette case. The cigarettes are restricted within a cavity with a specific shape and size, which has a fixing and squeezing effect on the cigarettes, causing the conventional round cigarettes to be changed into cigarettes with a hexagonal cross-section and enabling them to be loaded into existing standard packaging boxes (square cavities) without the need to redesign the box structure, thus avoiding the problems of high cost and cumbersome steps caused by directly producing hexagonal cigarettes through mechanical equipment in the prior art.

[0032] 2. The present invention provides an inner packaging paper for hexagonal cigarettes. There is no need to add new cigarette production equipment or redesign the cigarette box structure, and the cost is low. Only through the newly designed inner packaging paper for hexagonal cigarettes and its folding method can the shape of the cigarettes be changed, and the outer packaging requirements of cigarettes with a hexagonal cross-section are met. The inner cavity partitions are all 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 squeezing of the packaging boxes and not easily changing shape, avoiding the inconvenience in storage and transportation caused by putting pre-prepared hexagonal cigarettes into conventional cigarette packaging boxes in the prior art, and also avoiding separately preparing hexagonal cigarette packaging boxes that match the hexagonal cigarettes. In addition, the jolting during transportation is more conducive to the transformation of the formation of the cigarettes.

[0033] 3. The present invention provides a brand-new folding method for an inner packaging paper for hexagonal cigarettes for consumers, meeting the psychology of the public who like new and novel things. The use experience of consumers is optimized through the structure of the movable and turn-up cigarette positioning partition sleeve, which is convenient for taking cigarettes and can better cultivate consumers' trust and satisfaction in the brand; in the future, 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.

[0043] The folding method of the inner packaging paper includes the following steps:

[0044] a. There are multiple longitudinal crease lines 13 on the inner cavity partition 1. Fold the inner cavity partition 1 along the crease lines 13 repeatedly to fold out trapezoidal protrusions 11 and trapezoidal grooves 12 with trapezoidal cross-sections connected in sequence.

[0045] b. Stack the folded inner cavity partitions 1 face to face, with the trapezoidal protrusions 11 of the upper inner cavity partition 1 opposite to the trapezoidal grooves 12 of the lower inner cavity partition 1, to form 7 cigarette accommodating cavities with hexagonal cross-sections connected in sequence.

[0046] The distances between the multiple longitudinal crease lines 13 on the inner cavity partition 1 are equal, so that the upper sides and two waists of the trapezoidal protrusions 11 and the trapezoidal grooves 12 formed by folding are equal, and 7 cigarette accommodating cavities with regular hexagonal cross-sections connected in sequence are formed.

[0047] A cigarette case for hexagonal cigarettes made of the inner packaging paper described above. The cigarette case further includes a case body 2. The inner packaging paper formed by folding the inner packaging paper is located in the case body 2. The cigarette accommodating cavity fixes and presses the cigarettes, making the cigarettes hexagonal and accommodating them therein.

[0048] The cigarette case is a conventional flip-top handmade cigarette packaging box.

[0049] The inner cavity partition 1 has 4 layers. By stacking the 4 layers of the folded inner cavity partition 1 face to face, three layers of cigarette accommodating cavities, namely upper, middle, and lower layers, can be formed.

[0050] The upper and lower layer cigarette accommodating cavities include 7 hexagon-shaped cavities connected in sequence. The middle layer cigarette accommodating cavity includes 6 hexagon-shaped cavities connected in sequence. That is to say, the upper and lower layers can accommodate 7 cigarettes 3, while the middle layer can accommodate 6 cigarettes 3.
