Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to an environmentally friendly antibacterial corrugated cardboard box. Background Technology

[0002] Corrugated cardboard boxes are made from corrugated cardboard through die-cutting, creasing, stapling, or gluing. Compared to plastic boxes, corrugated cardboard boxes are the most widely used packaging products and are more environmentally friendly, belonging to green and environmentally friendly products. Corrugated cardboard boxes are often used for warehousing and transporting goods, and they also serve to beautify and promote products.

[0003] For the packaging of some foods, existing technologies mostly use plastic boxes, which are not environmentally friendly. If corrugated cardboard boxes are used, especially in humid environments or during cold chain transportation, bacteria, viruses and other microorganisms can easily grow on the surface and inside of the corrugated cardboard boxes, causing food spoilage. The antibacterial effect is relatively poor. At the same time, corrugated cardboard boxes are inevitably subjected to squeezing and collisions during use, which can easily lead to the collapse, deformation or even damage of the corrugated cardboard boxes, and their pressure resistance is relatively poor.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

The structure of the first film 29 is the same as that of the fourth film 32, and the structure of the third film 31 is the same as that of the sixth film. The area of ​​the first film 29 is larger than that of the third film 31. When folded, the first film 29 is folded inward by 90 degrees, and the first adhesive sheet 35 is folded outward by 180 degrees along the first fold line. Adhesive is applied to the side of the first adhesive sheet 35 away from the first film 29. The second film 30, the third... The first adhesive sheet 39 and the second adhesive sheet 30 are folded inward by 90 degrees and are both bonded to the first adhesive sheet 35. The second adhesive sheet 37 is folded outward by 180 degrees along the second fold line. Adhesive is applied to the side of the second adhesive sheet 37 away from the fourth adhesive sheet 32. The fifth adhesive sheet 33 and the sixth adhesive sheet 34 are folded inward by 90 degrees and are both bonded to the second adhesive sheet 37. After folding, the first adhesive sheet 29, the second adhesive sheet 30, the third adhesive sheet 31, the fourth adhesive sheet 32, the fifth adhesive sheet 33 and the sixth adhesive sheet 34 are stacked in order from top to bottom. This arrangement has relatively good load-bearing capacity, and only requires the addition of a glue spraying device during production. Folding is relatively simple, which is conducive to mechanized box making and can improve production efficiency.

[0022] The box lid includes a first cover plate 63, a second cover plate 64, a third cover plate 65, a fourth cover plate 66, a fifth cover plate 67, and a sixth cover plate 68, which are arranged sequentially and located on the same plane when unfolded.

When folding, first fold the third cover plate 65 and the sixth cover plate 68, then fold the second cover plate 64 and the fifth cover plate 67, then fold the first cover plate 63 and the fourth cover plate 66. Finally, use tape (this tape is not part of this embodiment and needs to be prepared separately when using) to seal the gap between the first cover plate 63 and the fourth cover plate 64, thereby completing the encapsulation.

[0023] The connecting plate 60 is attached to the inner side of the sixth side plate 24. The first side plate 10 and the fourth side plate 22 have the same structure and are arranged in parallel. The second side plate 20 and the fifth side plate 23 have the same structure and are arranged in parallel. The third side plate 21 and the sixth side plate 24 have the same structure and are arranged in parallel. The included angle between the first side plate 10 and the second side plate 20 is an obtuse angle. The included angle between the second side plate 20 and the third side plate 21 is an obtuse angle. The third side plate 21 and the fourth side plate 24 are arranged perpendicularly. The first side plate 10, the second side plate 20, and the third side plate 21 together form a first chamfer structure. The fourth side plate 22, the fifth side plate 23, and the sixth side plate 24 together form a second chamfer structure. Specifically, the included angle between the first side plate 10 and the second side plate 20 is 135 degrees. The included angle between the second side plate 20 and the third side plate 21 is also 135 degrees. The length of the first side plate 10 is greater than the length of the third side plate 21. The length of the third side plate 21 is greater than the length of the second side plate 20.

[0024] The box contains a reinforcing structure, including a first reinforcing plate 25, a third reinforcing plate 27, and a fourth reinforcing plate 28. The first reinforcing plate 25 is fixedly bonded to the inner side of the first side plate 10 and arranged parallel to it. The side of the first reinforcing plate 25 facing the sixth side plate 24 abuts against the inner side of the connecting plate 60. Specifically, the height of the first reinforcing plate 25 is the same as the height of the first side plate 10, and the height of the connecting plate 60 is the same as the height of the first side plate 10. The width of the first reinforcing plate 25 is smaller than the width of the first side plate. The third reinforcing plate 27 is fixedly bonded to the inner side of the third side plate 21 and arranged parallel to it. The fourth reinforcing plate 28 is fixedly bonded to the inner side of the fourth side plate 24 and arranged parallel to it. Specifically, the height of the third reinforcing plate 27 is the same as the height of the fourth reinforcing plate 28. The height of the third side plate 27 is the same as the height of the third side plate 21. The width of the third reinforcing plate 27 is less than the width of the third side plate 21, and the width of the fourth reinforcing plate 28 is less than the width of the fourth side plate 24. The third reinforcing plate 27 and the fourth reinforcing plate 28 are abutted or integrally connected. This utility model has antibacterial coatings 45 on the side of the face paper layer 41 away from the inner paper layer 43 and on the side of the inner paper layer 43 away from the face paper layer 41, which has a relatively good antibacterial effect. In addition, by setting the first corner structure and the second corner structure, the compressive strength is effectively improved. At the same time, the connection position between the first side plate 10 and the sixth side plate 24 is reinforced and supported by the cooperation of the first reinforcing plate 25 and the connecting plate 60, and the connection position between the third side plate 23 and the fourth side plate 24 is reinforced and supported by the cooperation of the third reinforcing plate 27 and the fourth reinforcing plate, which enhances the strength of the overall structure and has relatively good compressive performance.

[0025] Preferably, the corrugated paper layer 42 includes a first wavy corrugated paper 44, both sides of which are coated with water-resistant adhesive. The first wavy corrugated paper 44 includes alternating crests and troughs. Each crest of the first wavy corrugated paper 44 is simultaneously bonded to the side of the face paper layer 41 facing the inner paper layer 42, and each trough of the first wavy corrugated paper 44 is simultaneously bonded to the side of the inner paper layer 43 facing the face paper layer 41. The water-resistant adhesive is a water-resistant adhesive made of polystyrene-acrylate emulsion and modified oxidized starch adhesive. It should be noted that the water-resistant adhesive made of polystyrene-acrylate emulsion and modified oxidized starch adhesive is a conventional water-resistant adhesive. By coating the side of the inner paper layer 43 facing the face paper layer 41 and the side of the face paper layer 41 facing the inner paper layer 43 with water-resistant adhesive, the strength of the corrugated paperboard is effectively improved, and the compressive strength is further improved.

[0026] Preferably, the antibacterial coating 45 is a hydrophobic and heat-insulating coating 24 made by compounding peony root extract with sodium alginate and β-cyclodextrin and then combining it with polyvinyl alcohol. In production, an antibacterial coating solution made by compounding peony root extract with sodium alginate and β-cyclodextrin and then combining it with polyvinyl alcohol is first prepared. The antibacterial coating solution made by compounding peony root extract with sodium alginate and β-cyclodextrin and then combining it with polyvinyl alcohol is a conventional antibacterial coating solution. Then, a wire bar coater is used to coat the antibacterial coating solution on the side of the face paper layer 41 away from the inner paper layer 43 and the side of the inner paper layer 43 away from the face paper layer 41. After curing and drying under natural conditions, the antibacterial coating 45 is formed, which has a relatively good antibacterial effect and is beneficial for the storage of items.

[0027] Preferably, the first corrugated paper 44 has a first groove formed on the side facing the inner paper layer 43 at positions corresponding to each crest, and a second groove formed on the side facing the outer paper layer 41 at positions corresponding to each trough. Each first groove contains a drying strip 48, and each second groove contains an antibacterial strip 49. Specifically, the drying strip 48 is fixedly attached to each first groove, and the antibacterial strip 49 is fixedly attached to each second groove. This arrangement allows the drying strip 48 to dry the air inside the box, and the antibacterial strip 49 to effectively inhibit bacterial growth inside the box, creating a dry and sterile environment that is beneficial for storing items and further enhances the antibacterial effect.

[0028] The length direction of the box body is defined by the extension direction of the fold line between the first side plate 10 and the first bottom plate 29, and the width direction of the box body is defined by the extension direction of the fold line between the third side plate 21 and the third bottom plate 31.

[0029] Preferably, the bottom of the box body is provided with a hollow bottom plate 50. When an item is placed in the box body, the bottom plate 50 distributes the weight of the item, avoiding excessive pressure concentration. The bottom plate 50 includes a seventh side plate 71, an eighth side plate 72, a ninth side plate, and a tenth side plate 73 that are sequentially connected and located on the same plane when unfolded. A third adhesive piece (not shown in the figure) is integrally connected to the side of the seventh side plate 71 away from the eighth side plate 72. The third adhesive piece is attached to the inner surface of the tenth side plate 73, or the third adhesive piece is integrally connected to the side of the tenth side plate 73 away from the ninth side plate, and the third adhesive piece is attached to the inner surface of the seventh side plate 71. On the side, the seventh side plate 71, the eighth side plate 72, the ninth side plate, and the tenth side plate 73 together enclose a rectangular frame with a first cavity. The through direction of the first cavity of the rectangular frame is the same as the length direction of the box. The eighth side plate 72 is located directly above the tenth side plate 73. It should be noted that the cross-sectional outer contour shape of the bottom plate 50 is the same as the cross-sectional outer contour of the space enclosed by the first side plate 10, the second side plate 20, the third side plate 21, the sixth reinforcing plate 62, the fourth side plate 22, the fifth side plate 23, the sixth side plate 24, and the fifth reinforcing plate 61, ensuring that the bottom plate 50 can be placed at the bottom of the box.

[0030] Two or more vertically arranged corrugated partitions 51 are inserted on the eighth side panel 72. Each corrugated partition 51 divides the inner cavity of the box into multiple chambers. This arrangement prevents items placed in the inner cavity of the box from colliding with each other. Each corrugated partition 51 includes a partition paper 52. In the same corrugated partition 51, a second wavy corrugated paper 53 is fixedly glued to one side of the partition paper 52, and a third wavy corrugated paper 54 is fixedly glued to the other side of the partition paper 52. The second wavy corrugated paper 53 includes alternating second crests and second troughs, and the third wavy corrugated paper 54 includes alternating third crests and third troughs. The second corrugated paper 53 has a third groove formed on the side facing the partition paper 53 at a position corresponding to each second crest. The third corrugated paper 54 has a fourth groove formed on the side facing the partition paper 52 at a position corresponding to each third crest. The third and fourth grooves are connected to the first cavity. The second corrugated paper 53 has a first through hole for connecting the third groove to the inner cavity of the box. The third corrugated paper 54 has a second through hole for connecting the fourth groove to the inner cavity of the box. This arrangement allows the air in each cavity to circulate with the air in the first cavity.

[0031] The third side plate 21 and / or the sixth side plate 24 are provided with a second through hole 57 that communicates with the first cavity. This arrangement facilitates the air circulation between the inner cavity of the box and the outside, effectively preventing the items inside the box from decaying.

[0032] Preferably, the bottom of the box body is provided with multiple partitions 59 spaced apart along the length of the box body. Each partition 59 is a square frame formed by folding a piece of cardboard. Each partition 59 is arranged along the width of the box body. When the environmentally friendly antibacterial corrugated cardboard box provided in this embodiment is stacked, two adjacent environmentally friendly antibacterial corrugated cardboard boxes are separated by the partitions 59, which effectively prevents the problem of bacterial growth caused by the lack of air permeability between two adjacent environmentally friendly antibacterial corrugated cardboard boxes, and further improves the antibacterial effect.

[0033] Example 2: The difference between this embodiment and Embodiment 1 lies in the structure of the reinforcing structure, such as... Figure 6 As shown, the reinforcing structure includes a fifth reinforcing plate and a sixth reinforcing plate. The fifth reinforcing plate 61 is simultaneously fixedly bonded to the inner surface of both the first side plate 10 and the sixth side plate 24. The height of the fifth reinforcing plate 61 is the same as the height of the first side plate 10.
