Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a display packaging device. Background Technology

[0002] The shipping packaging for monitors typically uses a combination of inner cushioning pads and cardboard boxes. The inner cushioning pads are primarily made of materials such as EPS, EPE, corrugated cardboard, and pulp. However, all of these materials have significant drawbacks. For example, EPS cannot be recycled, easily causing white pollution, and is brittle, easily breaking upon impact and losing its protective function. EPE is expensive and difficult to recycle. Corrugated cardboard requires complex assembly and folding, increasing manual steps and labor costs. Pulp molding pads have insufficient strength in some areas, failing to meet the protective requirements of monitors.

[0003] Therefore, there is an urgent need to propose a display packaging device to solve the above problems. Utility Model Content

[0021] The top of the upper paper-plastic support has a chassis groove for accommodating the chassis.

[0022] In some optional embodiments, the supporting part is provided with reinforcing parts on the left and right sides respectively, and both ends of the reinforcing parts are connected to the third buffer part on the corresponding side.

[0023] The beneficial effects of this utility model are:

[0024] This utility model provides a display packaging device, including an outer box, left buffer paper-plastic, right buffer paper-plastic, lower support paper-plastic, and upper support paper-plastic. The outer box is formed by folding cardboard and includes a box body and a foldable upper cover plate that is disposed at the opening of the box body. Reinforcing paper tubes are embedded on both sides of the outer box, and the first buffer portions of the left and right buffer paper-plastics are snapped into the reinforcing paper tubes. Both the reinforcing paper tubes and the first buffer portions are embedded in the side panels of the box body, and the second buffer portions extend beyond the side panels. This makes the left and right buffer paper-plastics form an integral structure with the outer box. The lower support paper-plastic is snapped into the second buffer portion by a third buffer portion. This significantly enhances the integrity of the left, right, and lower support paper-plastics with the box body, strengthens the structural strength and compressive resistance of the corners of the packaging box, and provides better protection for the display. The bottom and circumference of the device provide safe and reliable cushioning protection. Combined with the reliable protection of the top of the monitor by the upper paper-plastic support, it can enhance the vertical compression resistance of the entire package, thereby ensuring the safety of the monitor during transportation. Secondly, by using the combination of the outer box and the paper-plastic, the outer box is folded and assembled with each paper-plastic, simplifying the molding process and helping to reduce production costs. Moreover, the outer box cardboard and each paper-plastic are made of paper materials, which are low in material cost and easy to recycle, meeting the requirements of low carbon and environmental protection. In addition, the left and right cushioning paper-plastics are molded separately, which makes it easier to adjust and optimize the cushioning structure of the paper-plastic for the specific structure of different monitor models. It is more flexible, and the combination of the two with the lower paper-plastic support provides stronger structural strength and cushioning effect than the paper-plastic alone.

[0054] like Figures 1 to 14 As shown, this embodiment provides a display packaging device, including an outer box 1, a left buffer paper-plastic 3, a right buffer paper-plastic 4, a lower support paper-plastic 5, and an upper support paper-plastic 6. The outer box 1 is formed by folding cardboard and includes a box body 11 and a foldable upper cover 18 that covers the opening of the box body 11. Reinforcing paper tubes 12 are embedded in the left and right side panels of the box body 11. The left and right buffer paper-plastic 3 and right buffer paper-plastic 4 are respectively disposed on the left and right sides inside the box body 11. Both include a first buffer portion 31 and a second buffer portion 32. The two ends of the first buffer portion 31 are respectively connected to the second buffer portion 32 at an included angle. A buffer section 31 can be snapped into the reinforcing paper tube 12 and is embedded in the left and right side panels of the box body 11. A second buffer section 32 extends to the outside of the side panels. The lower paper support 5 is snapped into the box body 11. The lower paper support 5 includes a support section 51 and a third buffer section 52. The support section 51 is adapted to the shape of the front of the display 100. The third buffer section 52 is erected on the front and rear sides of the support section 51 respectively. Both ends of the third buffer section 52 are snapped into the corresponding second buffer section 32. The bottom of the upper paper support 6 is adapted to the shape of the back of the display 100 and is configured to be stacked on the display 100.

[0055] By embedding reinforcing paper tubes 12 on the left and right sides of the outer box 1, and snapping the first buffer part 31 of the left buffer paper-plastic 3 and the right buffer paper-plastic 4 with the reinforcing paper tubes 12, the reinforcing paper tubes 12 and the first buffer part 31 are both embedded in the side panel of the box body 11, and the second buffer part 32 extends to the outside of the side panel, so that the left buffer paper-plastic 3 and the right buffer paper-plastic 4 form an integral structure with the outer box 1, and the lower support paper-plastic 5 is snapped with the second buffer part 32 through the third buffer part 52, which significantly enhances the integrity of the left buffer paper-plastic 3, the right buffer paper-plastic 4 and the lower support paper-plastic 5 with the box body 11, enhances the structural strength and pressure resistance of each corner of the packaging box, and provides a safe and reliable buffer protection for the bottom and circumference of the display 100. Combined with the reliable protection of the top of the display 100 by the upper support paper-plastic 6, the vertical pressure resistance of the entire packaging can be enhanced, thereby ensuring the transportation safety of the display 100.

[0056] Secondly, by combining the outer box 1 with paper and plastic, the outer box 1 is folded and assembled with each paper and plastic, which simplifies the forming process and helps to reduce production costs. Moreover, the outer box 1 cardboard and each paper and plastic are made of paper materials, which have low material costs and are easy to recycle, thus meeting the requirements of low carbon and environmental protection.

[0057] Furthermore, the left buffer paper plastic 3 and the right buffer paper plastic 4 are molded separately, which makes it easier to adjust and optimize the buffer structure of the paper plastic for the specific structure of different models of display 100. This makes it more flexible. Moreover, when the two are used together with the lower support paper plastic 5, their structural strength and buffering effect are stronger than that of a single paper plastic.

[0058] The outer side wall of each paper-plastic structure is provided with several grooves 65, which saves materials and reduces costs; on the other hand, it makes the paper-plastic structure have a concave-convex structure, so as to achieve a good cushioning and shock absorption effect.

[0059] like Figures 11-13 As shown, in some optional embodiments, the box body 11 includes a bottom plate 13, a front side plate 14, a rear side plate 15, a left side plate 16, and a right side plate 17. The reinforcing paper tube 12 is connected to the front side plate 14 and / or the rear side plate 15. The left side plate 16 and the right side plate 17 each include a first plate 161, a second plate 162, and a third plate 163 that are sequentially connected to the bottom plate 13. There are fold lines parallel to the bottom plate 13 between each adjacent plate. The first plate 161, the second plate 162, and the third plate 163 are folded inward along the fold lines to cover the reinforcing paper tube 12 and the first buffer part 31. When the lower support paper plastic 5 is installed in the box body 11, it can fix the third plate 163, thereby ensuring the structural stability and buffering effect of the left and right side walls of the box body 11.

[0060] In some optional embodiments, the side of the third plate 163 away from the second plate 162 is also connected to a folded edge 164. The folded edge 164 is folded inward and inserted between the first buffer part 31 and the bottom plate 13 to form a rolled edge structure, which further enhances the integrity of the outer box 1 and is conducive to improving the vertical pressure resistance of the display packaging device.

[0061] In some optional embodiments, the third plate 163 has a clearance groove 8 for avoiding the second buffer part 32. The second buffer part 32 extends to the receiving space of the box body 11 through the clearance groove 8. The second buffer part 32 has a slot 321. The third plate 163 is connected to a folding ear 165 that can engage with the slot 321. When the display packaging device is assembled, the folding ear 165 is sandwiched between the third buffer part 52 and the second buffer part 32, further enhancing the structural strength of the four corners of the box body 11.

[0062] In some optional embodiments, both ends of the third buffer part 52 are inserted into the corresponding side clearance groove 8, thereby limiting the upper and lower positions of the lower paper-plastic 5 through the outer box 1.

[0063] In some optional embodiments, the supporting part 51 is provided with reinforcing parts 53 on the left and right sides respectively, and both ends of the reinforcing parts 53 are connected to the corresponding side third buffer part 52 to enhance the structural strength and stiffness of the lower paper-plastic 5 on the left and right sides.

[0064] In some optional embodiments, the reinforcing paper tube 12 includes a separate first paper tube 121 and a second paper tube 122. The first paper tube 121 is connected to the rear side plate 15 at an angle, and the second paper tube 122 is connected to the front side plate 14 at an angle. Both the first paper tube 121 and the second paper tube 122 are engaged with the first buffer part 31, which can ensure the connection strength between the front side plate 14 and the rear side plate 15 and the left and right side plates, and improve the structural stability of the outer box 1.

[0065] like Figure 1 As shown, in some optional embodiments, upper cover plates 181 are connected to both sides of the upper cover plate 18. The upper cover plates 181 are configured to be inserted between the third plate 163 and the upper support paper plastic 6 to improve the sealing effect of the upper cover plate 18 on the opening of the box body 11 and prevent the display 100 accessories from coming out of the gap between the upper cover plate 18 and the box body 11.

[0066] In some optional embodiments, a front cover plate 19 is connected to the side of the upper cover plate 18 away from the box body 11, and front cover flaps 191 are connected to both sides of the front cover plate 19. The front cover plate 19 is configured to cover the outside of the front side plate 14, and the front cover flaps 191 are configured to be inserted between the first plate 161 and the reinforcing paper tube 12 to achieve a stable connection between the box cover and the box body 11, improve the sealing effect of the opening of the box body 11, and prevent the box cover from being accidentally opened during transportation, resulting in the loss of contents.

[0067] like Figure 5 As shown, in some optional embodiments, the top of the upper paper-plastic support 6 is provided with a wire post 61, and the wire can be sleeved on the wire post 61 to prevent the paper-plastic from shedding powder due to the shaking and friction of the wire.

[0068] like Figure 1 Combination Figure 5 As shown, in some optional embodiments, at least one side panel of the box 11 has a dog hole 9, and the top of the upper paper-plastic 6 has a wire groove 62 communicating with the dog hole 9. In specific scenarios, the display 100 needs to be equipped with different types of wires. The staff can directly take out the wires through the dog hole 9 or put the wires into the wire groove 62 without opening the outer box 1, which helps to simplify the packaging steps and improve production efficiency.

[0069] Among them, the dog hole 9 is covered with a foldable baffle 166 to cover the dog hole 9 and prevent the wire from coming out.

[0070] like Figure 1 Combination Figures 5-7 As shown, in some optional embodiments, the display 100 accessories include an L-shaped stand 200. The top of the upper paper / plastic support 6 has an L-shaped support groove 63 for accommodating the stand 200. The display packaging device also includes a paper card 7, which can be snapped into the corner of the support groove 63. When the stand 200 is accommodated in the support groove 63, the paper card 7 is placed between the stand 200 and the upper paper / plastic support 6. Because the stand 200 is L-shaped, the friction between its corner and the support groove 63 is relatively large. By placing the paper card 7, damage to the stand 200 or paper / plastic powder loss due to friction can be avoided.

[0071] The paper card 7 includes a body 71 and cards 72. The body 71 is adapted to the corner of the support groove 63. Multiple cards 72 are connected to the edge of the body 71. The cards 72 can be snapped into the buffer structure of the upper paper plastic 6 to make the connection between the paper card 7 and the upper paper plastic 6 stable.

[0072] In some alternative embodiments, the display 100 also includes a chassis 300, with a chassis groove 64 on the top of the upper paper-plastic 6 for receiving the chassis 300.

[0073] like Figures 8-10As shown, the unfolded structure of the cardboard forming the outer box 1 is as follows: A front side panel 14 and a rear side panel 15 extend outwards from the front and rear ends of the base plate 13, respectively. An upper cover plate 18 and a front cover plate 19 extend upwards from the rear side panel 15. Upper cover flaps 181 extend outwards from the left and right sides of the upper cover plate 18. Front cover flaps 191 extend outwards from the left and right sides of the front cover plate 19. First folding plates 20 extend outwards from the left and right sides of the rear side panel 15. The first folding plates 20 can be folded to form a first paper tube 121. The front panel 14 has a second folding plate 21 extending outward from the left and right sides. The second folding plate 21 can be folded to form a second paper tube 122. The bottom panel 13 has a first plate 161, a second plate 162, a third plate 163 and a folded edge 164 extending outward from the left side. The first plate 161 has a cutting line, and the three sides of the cutting line form a baffle 166. The third plate 163 has a dog hole 9 corresponding to the position of the baffle 166. The third plate 163 has folded ears 165 extending outward from the top and bottom sides.

[0074] Specifically, such as Figure 9 As shown, the first folding plate 20 includes a fourth plate 201 connected to the rear side plate 15. The fourth plate 201 extends upward sequentially to the fifth plate 202 and the sixth plate 203. The sixth plate 203 is L-shaped, and its horizontal part extends upward sequentially to the seventh plate 204, the eighth plate 205 and the ninth plate 206. Its vertical part extends upward sequentially to the tenth plate 207, the eleventh plate 208, the twelfth plate 209, the thirteenth plate 210, the fourteenth plate 211 and the fifteenth plate 212. The thirteenth plate 210 extends outward sequentially from the side away from the upper cover plate 18 to the sixteenth plate 213 and the seventeenth plate 214. The seventeenth plate 214 extends downward sequentially to the eighteenth plate 215 and the nineteenth plate 216. The seventh plate 204 and the tenth plate 207 are each provided with an insertion slot 23. The fourth plate 201 is respectively provided with a corresponding insertion tongue 22. The fourth plate 201 has a dog hole 9 corresponding to the position of the baffle 166.

[0075] like Figure 10 As shown, the second folding plate 21 includes a twentieth plate 217 connected to the front side plate 14. The twentieth plate 217 extends outward from the side away from the front side plate 14 in sequence to form a twentieth plate 218, a twentieth plate 219, a twentieth plate 220, and a twentieth plate 221. The twentieth plate 219 extends upward to form a twentieth plate 222. The twentieth plate 222 extends outward from the left and right sides of the twentieth plate 222 in sequence to form a twentieth plate 223 and a twentieth plate 224. The twentieth plate 221 extends upward in sequence to form a twentieth plate 225, a twentieth plate 226, a twentieth plate 227, and a twentieth plate 228. The twentieth plate 217 is provided with a tongue 22, the twentieth plate 220 is provided with a corresponding slot 23, the twentieth plate 221 is provided with a tongue 22, and the twentieth plate 227 is provided with a corresponding slot 23.

[0076] Each adjacent board has a crease line.

[0077] Specifically, such as Figures 8 to 14 As shown, the process of folding the above-mentioned flat cardboard into an airplane box is as follows:

[0078] S1: Fold each plate of the first folding plate 20 inward along the fold lines and connect it with the corresponding tongue 22 and the socket 23 to form the first paper tube 121. Fold each plate of the second folding plate 21 inward along the fold lines and connect it with the corresponding tongue 22 and the socket 23 to form the second paper tube 122.

[0079] S2: Using the base plate 13 as a reference, fold the front side plate 14 and the rear side plate 15 upwards by 90°, and fold the first paper tube 121 and the second paper tube 122 inwards by 90°; then, place the left buffer paper plastic 3 and the right buffer paper plastic 4 on the left and right sides of the box body 11 respectively, and make the first buffer part 31 snap into the reinforcing paper tube 12; fold the first plate 161, the second plate 162 and the third plate 163 in sequence, and insert the folded edge 164 between the first buffer part 31 and the base plate 13, so that the folded ear 165 is snapped into the slot 321;

[0080] S3: Place the lower paper-plastic 5 into the box body 11, so that the third buffer part 52 is engaged with the second buffer part 32, and both ends of the third buffer part 52 are inserted into the relief groove 8, and the folded ear 165 is clamped between the third buffer part 52 and the second buffer part 32.

[0081] S4: Place the display 100 face down on the support 51, and stack the upper paper plastic 6 on the display 100. Place each accessory of the display 100 at the corresponding position on the top of the upper paper plastic 6.

[0082] S5: Fold the upper cover flap 181 upwards by 90°, close the upper cover 18, and insert the upper cover flap 181 between the third plate 163 and the upper support paper plastic 6. Fold the front cover flap 191 upwards by 90°, close the front cover 19, and insert the front cover flap 191 between the first plate 161 and the reinforcing paper tube 12.

[0083] It is easy to understand that the first paper tube 121 and the second paper tube 122 are both formed by multiple layers of cardboard, which have high structural strength.
