Description

Technical Field

[0001] This invention belongs to the field of smart packaging, and designs a printing intelligent prompt technology, specifically involving a cigarette box device with intelligent prompt labels and its printing method. Background Technology

[0002] The exquisite packaging of cigarette boxes often brings high added value to premium cigarettes. Intelligent cigarette box labels are considered a highly promising intelligent technology, boasting advantages such as low cost, mass production capability, information display, anti-counterfeiting interaction, and increased cigarette value. Common intelligent cigarette box labels typically employ optical and chemical techniques to create complex patterns with cigarette brand logos or informational messages, producing special visual effects under light or electricity to achieve intelligent labeling. Currently, intelligent cigarette box labels are widely used in the packaging of various brand-name cigarettes; however, these labels are usually directly visible, cannot be repeatedly displayed or hidden, and sometimes require external devices to operate. Self-driven intelligent cigarette box labels, on the other hand, can achieve self-driven intelligent prompts and reversible information display and hiding during natural user actions, without the need for external devices. With the continuous development of new materials and printing processes, it has become possible to fabricate intelligent cigarette box labels and related devices through full printing. This typically utilizes the optical and electrochemical characteristics of materials, as well as differences in electronegativity and potential, to achieve efficient and reversible intelligent prompting of target information and interactive language functions. Benefiting from printing technology, the integration, thinness, aesthetics, and clear indication of the smart cigarette box indicator and its related devices with the packaging materials not only enhance the user's product experience but also endow the smart cigarette box indicator with more advanced technological connotations. Summary of the Invention

The cigarette box device includes a cigarette box body with an outer layer of box body paper base and a cigarette box lid that can be opened and closed connected to the cigarette box body. A fan-shaped box lid paper base is provided between the cigarette box body and the cigarette box lid. A box body energy module for providing electrical energy is provided inside the cigarette box body. On the outer box body paper base adjacent to the box body energy module, from top to bottom, a contactor module for identifying the opening and closing state of the cigarette box, an intelligent prompting label for prompting according to the opening and closing state of the cigarette box, and a rectifier module for rectifying and distributing the electrical energy provided by the box body energy module are arranged sequentially.

[0005] The energy module of the box body includes an opposing conductive layer that is attached to the side of the cigarette box body on one side and an electronegative thin layer that is located on the other side of the opposing conductive layer and is attached to it. The electronegative thin layer is in contact with the base paper of the box lid.

Then, perform oxygen plasma treatment at a power of 70%.

[0013] S3: Mix water and polyvinyl alcohol in a mass ratio of (93-90):(7-10) to obtain a PVA solution. Then mix silver powder, polyvinylpyrrolidone and PVA solution in a mass ratio of 9:(1-3):(90-88) to obtain a paste for the opposing conductive layer, the top conductive layer and the first conductor.

[0014] S4: Using screen printing equipment, the paste in S3 is used as ink to print corresponding patterns on the inner side of the cigarette box, forming the opposing conductive layer and the first wire of the energy module of the box.

[0015] S5: Dry the opposing conductive layer and the first wire thoroughly in an oven;

[0016] S6: The electronegative material is attached to the surface of the opposing conductive layer with double-sided adhesive to form a thin electronegative layer of the box body energy module. The box cover paper base layer is then covered on the thin electronegative layer to finally obtain the box body energy module.

[0058] A method for printing and manufacturing a cigarette box device with intelligent prompts includes the following steps:

[0059] S1: Design the cigarette box size, contactor module structure, and rectifier module structure according to the quantity and size of the cigarettes. Design screen printing plates and spraying templates with special patterns according to the type and brand of cigarettes. Among them, the opposing conductive layer 2a, intelligent prompt label module 5b, rectifier module, contactor 8e, ion migration layer 4e, first prompt layer 2e, and second prompt layer 5e are designed to appropriate sizes. Design a 0.5mm thick polyethylene terephthalate film (PET) spraying template and screen printing plate with special patterns or information. Prepare for manufacturing according to the above structural parameters and printing parameters.

[0060] S2: First wipe with dish soap, then use deionized water and alcohol to ultrasonically clean the PET for 5 minutes, and then blow dry with nitrogen for later use; wipe the paper base of the box several times with alcohol and then blow dry with nitrogen for later use; in order to ensure that the conductive ink 1 can be well wetted on the PET, the PET must first be pretreated with oxygen plasma at a power of 70% for 5 minutes.

[0061] S3: The mass ratio of water and polyvinyl alcohol (PVA) is (93-90):(7-10), and a PVA solution is obtained by mixing. The mass ratio of silver powder, polyvinylpyrrolidone (PVP) and PVA solution is 9:(1-3):(90-88). The three are mixed and stirred at room temperature for 1 hour to prepare a slurry. The temperature is controlled at room temperature and ultrasonicated for 30 minutes to ensure that the silver powder is fully dispersed and uniform, so as to meet the requirements of screen printing.

[0062] S4: Using a screen printing machine with a mesh count of 150 meshes and a screen spacing of 2mm, the paste in S3 is used as ink to print the corresponding pattern on the cleaned inner side of the cigarette box body at a printing pressure of 0.25~0.40MPa and a printing speed of 7cm / s, forming the opposing conductive layer and the first wire of the box body energy module.

[0063] S5: Dry the opposing conductive layer and the first wire of the energy module in the box body in an oven at a drying temperature of 120℃ for 20 minutes;

[0064] S6: The strong electronic material is attached to the surface of the opposing conductive layer with double-sided adhesive with a thickness of 0.1mm to form an electronegative thin layer of the box body energy module. The box cover paper base layer is then covered on the electronegative thin layer to finally obtain the box body energy module.

[0065] S7: The volume ratio of 10 mg / mL silver nanowire-ethanol (AgNWs-EtOH) dispersion, methanol (MeOH), and 7 wt% starch paste is 1:(38.8~38.7):(0.2~0.3). The three are mixed and stirred at room temperature for 30 min, followed by sonication at low temperature for 30 s to ensure that the silver nanowires are fully and uniformly dispersed, resulting in spray ink a with a bottom conductive layer and a transparent conductive layer; 5 g of nano zinc oxide powder (ZnO) and 50 mL of trichloromethane (CHCl3) are mixed and dissolved to prepare ink 2, and sonicated at room temperature for 10 min to obtain spray ink b with a white oxide layer;

[0066] S8: Using a spray gun with a nozzle diameter of 1.5-2mm, the bottom conductive layer and white oxide layer of the rectifier module are sprayed and printed on the box body paper base layer and the pre-prepared first wire with spray ink a and spray ink b in S7 in sequence at a flow rate of 40-50cm / s. The layers are then dried on a hot table at a heating temperature of 150℃ for 5min to form the bottom conductive layer and white oxide layer of the rectifier module.

[0067] S9: Using a 2B pencil as the source of graphite material, the white oxide layer is completely covered by coating to form the black conductor layer of the rectifier module;

[0068] S10: The paste in S3 is printed on the black conductor layer using a screen printing machine with a mesh count of 150 and a screen pitch of 2mm. The printing pressure is 0.25-0.40MPa and the printing speed is 7cm / s. The paste is then dried in an oven at a heating temperature of 120℃ for 20min to form a thin film, which forms the top conductive layer and the second conductor of the rectifier module, thus obtaining the rectifier module.

[0069] S11: 1.5wt% poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT:PSS) aqueous dispersion, N,N-dimethylacetamide (DMAC) and acetonitrile (ACN) are mixed in a mass ratio of 17:(1~0.5):(2~2.5), and ultrasonicated at room temperature for 20 min to ensure uniform dispersion of PEDOT:PSS, to obtain the first prompt layer gravure printing ink c; aniline, 9.4wt% ammonium persulfate (APS) aqueous solution, dodecylbenzene sulfonic acid (DBSA) and 5.9wt% PVA aqueous solution are mixed in a volume ratio of 4:100:15:350 and stirred in an ice bath environment at 0℃ for 4 h to obtain polyaniline (PANI) slurry; then the PANI slurry is mixed with isopropanol in a volume ratio of 5:(1~5) and stirred for 1 h, and ultrasonicated at room temperature for 20 min to ensure full and uniform dispersion of PANI, to obtain the second prompt layer screen printing ink d;

[0070] S12: The gravure printing ink c in S11 is printed on the box body paper base layer using a gravure printing roller with a line count of 175 mesh, a cell depth of 50μm, and a screen angle of 53°. The ink is then printed at a printing pressure of 600N. After that, it is dried in an oven at a heating temperature of 105℃ for 30 minutes to form a blue film, which forms the first prompt layer of the intelligent prompt label.

[0071] S13: Using a spray gun with a nozzle diameter of 1.5-2mm, lactic acid is sprayed onto the first indication layer at a flow rate of 40-50cm / s through a PET spraying template to form a patterned transparent treatment layer. After standing for 30 minutes, it is placed on a 125℃ hot table and heated for 20 minutes to make the transparent treatment layer disappear, thus completing the treatment.

[0072] S14: Lithium hexafluorophosphate (LiPF6), starch and water are mixed in a mass ratio of (0.5-3):1:10 and stirred in an oil bath at 60°C for 2 hours to obtain a gel. The gel is then screen printed on the first prompt layer using a screen printing machine with a mesh count of 100 mesh and a screen pitch of 3 mm at a printing pressure of 0.2-0.3 MPa and a printing speed of 10 cm / s to form an ion migration layer, thus obtaining the lower half of the intelligent prompt label module.

[0073] S15: Using a spraying device with a nozzle diameter of 1.5-2mm, the spraying ink a in S7 is used to print on a PET pre-placed on a hot table at 150℃ at a flow rate of 40-50cm / s. Then, the PET is dried on the hot table at a heating temperature of 150℃ for 5 minutes to form a transparent film, which forms the transparent conductive layer of the intelligent prompt label module.

[0074] S16: Using a screen printing device with a mesh count of 200 and a screen spacing of 2mm, the screen printing ink d in S11 is printed on the transparent conductive layer at a printing pressure of 0.3-0.5MPa and a printing speed of 5cm / s to form the second prompt layer of the intelligent prompt label, thus obtaining the upper part of the intelligent prompt label;

[0075] S17: Apply UV-curable adhesive around the ion migration layer as an encapsulation bonding tape to form a rectangular closed area with a reserved gap in the first prompt layer. Cover the lower half of the smart prompt sign module with the upper half of the smart prompt sign module. Cure the UV-curable adhesive under the action of a UV lamp with a power of 100w / cm. Then, spray ink a between the first prompt layer and the second wire and between the transparent conductive layer and the second wire using a spray gun and dry the connection area at 150℃ for 5 minutes to form a smart prompt sign.

[0076] S18: Install a metal contactor with a thickness not greater than the height of the gap in the reserved gap on the rectangular closed area. It should be noted that the metal contactor is made of zinc sheet, aluminum sheet or iron sheet with a thickness of 0.01 to 0.3 mm. The metal contactor does not contact the ion migration layer. The connection with the contactor module is completed, and the cigarette box device with intelligent prompt label is finally obtained.

[0077] When in use, this device utilizes the user's natural action of opening the cigarette case. The case opens the lid, which actuates the contactor button 1c. At this time, the metal contactor 5c is inserted between the ion migration layer 4e and the first indication layer 2e of the intelligent indication module. Simultaneously, the paper base layer 5 of the case opens and rubs against the electronegative thin layer 4a. The electronegative thin layer 4a generates induced charge due to friction. The charge is conducted to the rectifier module through the opposing conductive layer 2a and the wire 3a, which are attached to the electronegative thin layer 4a. The rectifier module converts the alternating current into direct current, and then conducts the positive charge in the direct current through the wire 6b to the transparent conductive layer 6e of the intelligent indication module, driving the second indication layer 5e to change from yellow to green and finally to blue-purple. A current loop is formed between the metal contactor 5c, the ion migration layer 4e, and the first indication layer 2e. Due to the potential difference, the first indication layer 2e undergoes oxidation-reduction, changing from light blue to dark blue. The smart indicator displays a yellow pattern when it starts working; as the lid continues to open, the smart indicator displays prominent blue text and a green pattern; when the lid is opened multiple times, the smart indicator displays a prominent blue-purple pattern. On the one hand, the changing pattern reminds users of the health risks of smoking; on the other hand, the displayed content demonstrates the product's authenticity, anti-counterfeiting features, and high value, enhancing the reminder effect and user experience.
