Description

Technical Field

[0001] The present invention belongs to the technical field of cartons, and particularly relates to a carton for anti-drop and moisture-proof cigarettes. Background Art

[0002] Cartons are used to help store and transport various items. A carton for cigarettes is a kind of carton used to store and transport cigarettes. Existing cartons for cigarettes all use general cartons. For example, the compression-resistant carton for transportation with the application number CN119142641A includes: a packaging component; an anti-leakage component is provided inside the packaging component; an inner protection component is provided inside the packaging component; a cross-bracing component is provided inside the inner protection component; by rotatably connecting two sets of flipping plates inside the outer carton respectively, and making the interlocking plug plates press against each other when they cross, so as to avoid dispersion when receiving the weight of the goods, and it is convenient to prevent the goods from leaking out from the bottom by the way of mutual pressing, solving the problem that for the current traditional compression-resistant cartons, after being processed by a creasing device, they are usually adhesively formed with tape.

[0003] There will be some problems in the process of transporting and storing cigarettes with existing general cartons. For example, traditional corrugated cartons are easily deformed under pressure during long-distance transportation, resulting in damage to the inner cigarette strips by extrusion, especially the two ends are easily flattened. In addition, ordinary cartons are easily softened by moisture absorption in a humid environment. Tobacco is sensitive to humidity, and humidity will affect the quality of cigarettes. Summary of the Invention

[0004] The purpose of the present invention is to provide a carton for anti-drop and moisture-proof cigarettes, aiming to solve the technical problems that the carton is easily deformed under pressure during long-distance transportation and cannot prevent moisture in the prior art.

[0005] To achieve the above purpose, a carton for anti-drop and moisture-proof cigarettes provided by an embodiment of the present invention includes a carton body; a cavity is provided inside the carton body, and an anti-drop support component is provided inside the cavity. The anti-drop support component is used to assist in supporting the cavity, so that external force cannot easily force the cavity to change. The anti-drop support component includes a partition board; the partition board divides the cavity into an upper placement cavity and a lower drying cavity. Desiccants are placed in the drying cavity to achieve drying in the placement cavity. The carton body includes a corrugated paper layer in the middle, and moisture-proof layers are provided on the inner and outer sides of the corrugated paper layer. The moisture-proof layer includes the following preparation raw materials in weight percentages: 40-60% of waterborne acrylic resin, 5-15% of modified nano-silica, 10-20% of composite emulsion, 3-8% of calcium stearate, 2-5% of polyvinyl alcohol, and the balance is environmental protection solvent.

[0006] The preparation process of the moisture-proof layer includes the following steps: S1, weigh the aqueous acrylic resin, the modified nano-silica, the composite emulsion, the calcium stearate, the polyvinyl alcohol, and the environmental protection solvent according to the formula respectively; S2, add the aqueous acrylic resin into the reaction kettle, stir at a low speed of 300 rpm, add the environmental protection solvent, heat up to 45 °C, and keep it at a constant temperature for 10 min; S3, then slowly add the modified nano-silica, increase the rotation speed to 1000 rpm, and stir for 1 h; S4, then add the composite emulsion, calcium stearate, and polyvinyl alcohol in sequence, and stir until the system is uniform; S5, adjust the pH of the system to 8.0 - 8.5, pass through a 250-mesh nylon sieve, seal and cure for 48 hours, and roll coat or spray it onto the corrugated paper layer and then dry it at 80 - 120 °C to obtain the moisture-proof layer.

[0007] Optionally, the modified nano-silica is obtained by modifying nano-silica with a silane coupling agent.

[0008] Optionally, the composite emulsion is prepared by emulsifying chitosan (dissolved in 2% acetic acid) and paraffin in a mass ratio of 1:2 and neutralizing to pH = 6.5.

[0009] Optionally, the environmental protection solvent includes a mixture of water and ethanol.

[0010] Optionally, the anti-drop support assembly includes an upper plate and a lower plate; the upper plate and the lower plate are connected by four connecting columns, and the four connecting columns are respectively arranged at the four corners of the carton body and are closely attached to the corners.

[0011] Optionally, the connecting column is L-shaped, the right angle of the connecting column extends into the corner of the carton body, and both sides of the connecting column are closely attached to the inner wall of the carton body. The connecting column is used to strengthen the protection of the four edges and corners of the carton body.

[0012] Optionally, at least one clamping block is provided on each connecting column, and the partition board is arranged on the clamping block and divides the cavity into the upper placing cavity and the lower drying cavity.

[0013] Optionally, the connection mode between the upper plate and the lower plate and the four connecting columns is a detachable connection, and the detachable connection can be one of clamping connection, screw and screw hole connection, and bonding.

[0014] Optionally, an identification area is further provided outside the carton body. The identification area is provided with a plurality of identification color blocks, and each identification color block is provided with a reflective film. Tearing off the reflective film on the corresponding identification color block can expose the color of the identification color block for unified and quick identification.

[0016] The moisture-proof layer of the present invention has better moisture-proof performance than the products on the market through the improvement of the formula. At the same time, by adding the composite emulsion, the pores are filled to form a physical barrier layer, which reduces the water vapor transmission rate. Compared with adding paraffin emulsion alone, the moisture-proof effect is improved by 20%. At the same time, chitosan has a natural inhibitory effect on molds (such as Aspergillus niger) and bacteria.

[0035] Embodiment 1

[0036] According to Figures 1-6As shown, it includes a carton body 100; a cavity 110 is provided in the carton body 100, and an anti-fall support component 200 is provided in the cavity 110. The anti-fall support component 200 is used to auxiliary support the cavity 110 so that external force cannot easily force the cavity 110 to change, and the anti-fall support component 200 includes a partition plate 210; the partition plate 210 divides the cavity 110 into an upper placement cavity 111 and a lower drying cavity 112, and a desiccant is placed in the drying cavity 112 to achieve drying in the placement cavity 111. The carton body 100 includes a corrugated paper layer 120 in the middle, and a moisture-proof layer 130 is provided on the inner and outer sides of the corrugated paper layer 120.

[0037] Specifically, by providing the anti-fall support component 200, the carton can be less susceptible to squeezing and deformation during transportation, so that external force cannot easily force the cavity 110 to change, thereby ensuring that the cigarettes inside will not be deflated. By providing the moisture-proof layer 130, the external water vapor can be effectively isolated to prevent water vapor from entering the box body. At the same time, a drying chamber 112 is provided inside the box body. When the external box body is damaged and water vapor enters the box body, the drying chamber 112 can dry the placement chamber 111, thereby ensuring the storage conditions of the cigarettes.

[0038] according to Figures 3-5 As shown, the anti-fall support assembly 200 includes an upper plate 220 and a lower plate 230; the upper plate 220 and the lower plate 230 are connected by four connecting columns 240, and the four connecting columns 240 are respectively arranged at the four angles of the carton body 100 and fit closely with the angles. The connecting column 240 is L-shaped, and the right angle of the connecting column 240 penetrates into the angle of the carton body 100, and the two sides of the connecting column 240 are close to the inner wall of the carton body 100. The connecting column 240 is used to strengthen the protection of the four corners of the carton body 100.

[0039] Specifically, by having four connecting posts 240 closely attached to four corners in the cavity 110 , the four corners can be effectively prevented from being deformed due to collision, thereby ensuring space in the placement cavity 111 .

[0040] according to Figures 4-6 As shown, each connecting column 240 is provided with at least one clamping block 241, and the partition plate 210 is provided on the clamping block 241 and divides the cavity 110 into an upper placement cavity 111 and a lower drying cavity 112. The partition plate 210 is provided with a plurality of pulling belts 400, which can drive the partition plate 210 to pull and move upward.

[0041] Specifically, the partition plate 210 is arranged on the clamping block 241. The material of the partition plate 210 is required to have a certain strength and will not bend in the middle. At the same time, desiccants will be placed in the drying cavity 112, which will play a supporting role for the partition plate 210. Further, after the cigarette storage is full, one end of the pulling belt 400 is on the top layer of the cigarettes. After opening the upper plate 220, pulling the pulling belt 400 can pull out the cigarette placement cavity 111 filled with cigarettes together with the partition plate 210. This avoids the trouble of taking out cigarettes one by one and allows for a whole-piece removal.

[0042] According to Figure 3 As shown, the connection method between the upper plate 220 and the lower plate 230 and the four connecting columns 240 is a detachable connection, and the detachable connection can be one of snap connection, screw and screw hole connection, and bonding. Specifically, the detachable connection can facilitate assembly and transportation and does not occupy too much space. When transporting in a carton, the carton can be folded, and the anti-drop support assembly 200 can be disassembled for transportation, saving transportation costs.

[0043] According to Figure 1 As shown, an identification area 300 is also provided outside the carton body 100. The identification area 300 is provided with a plurality of identification color patches 310, and each identification color patch 310 is provided with a reflective film 320. Tearing off the reflective film 320 on the corresponding identification color patch 310 can expose the color of the identification color patch 310 for unified and quick identification.

[0044] Specifically, setting the identification area 300 can facilitate transportation and handling. The same batch and brand of cigarettes are unified with the same color, so there is no need to open the carton to check which kind of cigarettes during transportation and unloading, which is more simple and fast.
