Description

Technical Field

[0001] This invention relates to the field of cardboard box technology, and more particularly to a hydrophobic and moisture-proof corrugated cardboard box. Background Technology

[0002] As is well known, existing companies typically produce corrugated cardboard boxes by cutting whole sheets of corrugated paper into corrugated cardboard of the desired shape, and then folding and gluing the corrugated cardboard to form the required corrugated cardboard box.

[0003] Corrugated cardboard boxes, made from corrugated paper, have good structural strength and are therefore frequently used in daily life. However, they are not waterproof or moisture-proof. When corrugated cardboard boxes are exposed to rain or placed in humid environments, the corrugated paper can soften due to water erosion, causing the boxes to gradually collapse and deform, thus losing their storage function. Summary of the Invention

[0004] This invention aims to at least partially solve one of the problems of the prior art. To this end, this invention proposes a hydrophobic and moisture-proof corrugated cardboard box, which helps improve the waterproof and moisture-proof performance of the corrugated cardboard box, enabling it to better package and store goods.

[0005] According to certain embodiments of the present invention, a hydrophobic and moisture-proof corrugated cardboard box includes a corrugated cardboard box body and a supporting base frame. The corrugated cardboard box body has an internal receiving cavity with an open upper part. The upper front and rear sides of the corrugated cardboard box body each have a first sealing plate, and the upper left and right sides of the corrugated cardboard box body each have a second sealing plate. The two first sealing plates, the two second sealing plates, and the corrugated cardboard box body are integrally formed. The upper surface of the supporting base frame has a mounting groove in the middle. The supporting base frame is installed on the lower part of the corrugated cardboard box body, and the lower part of the corrugated cardboard box body is embedded in the mounting groove. The bottom surface of the supporting base frame has multiple detachable supporting legs, all of which are arranged at intervals around the outer periphery of the supporting base frame. The corrugated cardboard box body is constructed by folding a composite board, the composite board including corrugated cardboard. One side surface of the corrugated cardboard is bonded with a pearl cotton layer, and the side surface of the pearl cotton layer away from the corrugated cardboard is bonded with a hydrophobic coating.

[0006] A hydrophobic and moisture-proof corrugated cardboard box according to the present invention has the following beneficial effects: By using a composite board folded to form the corrugated cardboard box body, the composite board includes corrugated cardboard, one side of which is bonded with a layer of pearl cotton, and the side of the pearl cotton layer away from the corrugated cardboard is bonded with a hydrophobic coating. This allows water to quickly slide off along the hydrophobic coating when the corrugated cardboard box body, shortening the time water stays on the surface of the corrugated cardboard box body. Therefore, water will not penetrate into the interior of the composite board. Moreover, the pearl cotton layer can isolate rainwater, achieving the purpose of waterproofing and moisture-proofing. In addition, a support frame is provided at the bottom of the corrugated cardboard box body, which keeps the corrugated cardboard box body away from the ground. Even if there is standing water or dampness on the ground, water cannot contact and soak the bottom of the corrugated cardboard box body, greatly improving the waterproof and moisture-proof performance of the corrugated cardboard box in this embodiment. Therefore, the corrugated cardboard box of this application can better load and store items.

[0007] In some embodiments of the present invention, a first waterproof membrane layer is provided between the corrugated cardboard and the pearl cotton layer.

[0008] In some embodiments of the present invention, a second waterproof membrane layer is provided on the surface of the corrugated cardboard away from the first waterproof membrane layer.

[0009] In some embodiments of the present invention, a wear-resistant coating is provided on the side of the hydrophobic coating away from the pearl cotton layer.

[0010] In some embodiments of the present invention, the thickness of the wear-resistant coating is 100-200 micrometers.

[0011] In some embodiments of the present invention, the thickness of the hydrophobic coating is 50-200 micrometers.

[0012] In some embodiments of the present invention, the thickness of the pearl cotton layer is 3-4 mm.

[0013] In some embodiments of the present invention, the lower part of the corrugated cardboard box body is embedded in the mounting groove, and the bottom surface of the corrugated cardboard box body is bonded to the bottom wall of the mounting groove.

[0014] In some embodiments of the present invention, the bottom of the support base is provided with a plurality of hollow holes, and the plurality of hollow holes are arranged at intervals on the bottom wall of the mounting groove.

[0015] In some embodiments of the present invention, the bottom surface of the support base is provided with a plurality of threaded connection holes, and the upper part of each support leg is provided with a threaded connection rod that can be threadedly connected to the threaded connection hole.

[0021] Figures 1 to 6This is a schematic diagram of one embodiment of a hydrophobic and moisture-proof corrugated cardboard box according to the present invention. A hydrophobic and moisture-proof corrugated cardboard box (hereinafter sometimes simply referred to as "corrugated cardboard box") is provided according to this embodiment. A hydrophobic and moisture-proof corrugated cardboard box includes a corrugated cardboard box body 100 and a supporting base frame 200. In this embodiment, the corrugated cardboard box body 100 is generally rectangular in shape. The corrugated cardboard box body 100 has an internal receiving cavity 110 with an open upper part. The upper front side and the upper rear side of the corrugated cardboard box body 100 each have a first sealing plate 120. The upper left side and the upper right side of the corrugated cardboard box body 100 each have a second sealing plate 130. The two first sealing plates 120, the two second sealing plates 130, and the corrugated cardboard box body 100 are an integral structure. Specifically, the two first sealing plates 120 are arranged one-to-one on the upper left side and the upper right side of the corrugated cardboard box body 100, and the two second sealing plates 130 are arranged one-to-one on the upper left side and the upper right side of the corrugated cardboard box body 100. Each first sealing plate 120 is connected to the corrugated cardboard box body 100 by a crease, and each second sealing plate 130 is connected to the corrugated cardboard box body 100 by a crease. In this embodiment, the support base 200 is rectangular in shape, and a mounting groove 210 is provided in the middle of the upper surface of the support base 200. The shape of the mounting groove 210 is adapted to the shape of the lower part of the corrugated carton body 100. The support base 200 is installed on the lower part of the corrugated carton body 100, and the lower part of the corrugated carton body 100 is embedded in the mounting groove 210. Multiple support legs 220 are detachably installed on the bottom surface of the support base 200. All support legs 220 are arranged at intervals around the outer periphery of the support base 200. The corrugated carton body 100 is constructed by folding a composite board, which includes a corrugated cardboard 300. A pearl cotton layer 310 is bonded to one side surface of the corrugated cardboard 300, and a hydrophobic coating 320 is bonded to the side surface of the pearl cotton layer 310 away from the corrugated cardboard 300. When making the corrugated cardboard box body 100, the composite board is cut into a set shape, and then the cut composite board is folded and glued to form the corrugated cardboard box body 100. It should be noted that when the composite board is folded and glued to form the corrugated cardboard box body 100, the side of the composite board with the hydrophobic coating 320 is the outer side of the corrugated cardboard box body 100.

[0022] The corrugated cardboard box body 100 is constructed by folding and bonding composite boards. The composite board includes corrugated cardboard 300. One side surface of the corrugated cardboard 300 is bonded with a pearl cotton layer 310, and the side surface of the pearl cotton layer away from the corrugated cardboard 300 is bonded with a hydrophobic coating 320. This allows water to quickly slide off along the hydrophobic coating 320 when the corrugated cardboard box body 100, shortening the time water stays on the surface of the corrugated cardboard box body 100. Therefore, water will not penetrate into the interior of the composite board. Moreover, the pearl cotton layer can isolate rainwater, achieving the purpose of waterproofing and moisture-proofing. In addition, a support frame 200 is provided at the bottom of the corrugated cardboard box body 100. The support frame 200 can keep the corrugated cardboard box body away from the ground. Even if there is water accumulation or dampness on the ground, water cannot contact and soak the bottom of the corrugated cardboard box body 100, greatly improving the waterproof and moisture-proof performance of the corrugated cardboard box in this embodiment. Therefore, the corrugated cardboard box of this application can better load and store items.

[0023] Reference Figure 1 and Figure 6 To further enhance the moisture-proof performance of corrugated cardboard boxes, in some embodiments of the present invention, a first waterproof membrane layer 330 is provided between the corrugated cardboard 300 and the pearl cotton layer 310. Specifically, the first waterproof membrane layer 330 is bonded to the surface of the corrugated cardboard 300 facing the pearl cotton layer 310, and the pearl cotton layer 310 is bonded to the surface of the first waterproof membrane layer 330 away from the corrugated cardboard 300. By providing the first waterproof membrane layer 330 between the corrugated cardboard 300 and the pearl cotton layer 310, even if external water penetrates the pearl cotton layer 310, the first waterproof membrane layer 330 can prevent water from contacting and penetrating the corrugated cardboard 300, thereby improving the waterproof and moisture-proof performance of the corrugated cardboard box of this embodiment.

[0024] In some embodiments of the present invention, a second waterproof membrane layer 340 is provided on the surface of the corrugated cardboard 300 away from the first waterproof membrane layer 330. In this embodiment, the second waterproof membrane layer 340 and the first waterproof membrane layer 330 are made of the same material; both the first and second waterproof membrane layers 330 are PVC or PE waterproof membranes, depending on actual needs. In this embodiment, the second waterproof membrane layer 340 is bonded to the surface of the corrugated cardboard 300 away from the first waterproof membrane layer 330. By adopting the above structure, the inner surface of the corrugated cardboard box body 100 also has a waterproof membrane. In some cases, when the items placed inside the receiving cavity 110 become damp or slightly seep water, the second waterproof membrane layer 340 can also prevent water from contacting and penetrating the corrugated cardboard 300, thereby allowing the corrugated cardboard 300 to maintain its original structural strength. This not only improves the waterproof and moisture-proof performance of the corrugated cardboard box in this embodiment, but also allows the corrugated cardboard box to hold damp items, expanding the application range of the corrugated cardboard box.

[0025] In some embodiments of the present invention, an abrasion-resistant coating 350 is provided on the surface of the hydrophobic coating 320 away from the pearl cotton layer 310. In this embodiment, the abrasion-resistant coating 350 is a fluoroplastic coating layer. During production, the abrasion-resistant coating 350 is formed by coating the surface of the hydrophobic coating 320 with a fluoroplastic coating. The thickness of the abrasion-resistant coating 350 is 100-200 micrometers, specifically, the thickness of the abrasion-resistant coating 350 is 150 micrometers. By adopting the above structure, a protective layer is formed on the surface of the hydrophobic coating 320, which can prevent the hydrophobic coating 320 from being worn and affecting the hydrophobic properties of the corrugated cardboard box.

[0026] In some embodiments of the present invention, the hydrophobic coating 320 is a fluorocarbon wax coating layer, and the thickness of the hydrophobic coating 320 is 50-200 micrometers, specifically, the thickness of the hydrophobic coating 320 is 100 micrometers. During production, the above-mentioned hydrophobic coating 320 is obtained by applying the fluorocarbon wax coating to the surface of the pearl cotton layer 310 away from the corrugated cardboard 300. It should be noted that, in addition to the above-mentioned fluorocarbon wax coating layer, the hydrophobic coating 320 can also be a polysiloxane coating layer, a silicone resin coating layer, or an organosilicon-modified acrylic coating layer, depending on actual needs.

[0027] To ensure good water resistance, in some embodiments of the present invention, the thickness of the pearl cotton layer 310 is 3-4 mm. By employing the above structure, the pearl cotton layer 310 has sufficient thickness to repel water, greatly improving the waterproof and moisture-proof performance of the corrugated cardboard box in this embodiment.

[0028] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the lower part of the corrugated carton body 100 is embedded in the mounting groove 210, and the bottom surface of the corrugated carton body 100 is bonded to the bottom wall of the mounting groove 210. By adopting the above structure, when the support base 200 is installed on the corrugated carton body 100, the support base 200 and the corrugated carton body 100 can be bonded together, thereby allowing the support base 200 to be firmly installed on the lower part of the corrugated carton body 100. This prevents the support base 200 from accidentally falling off when the user is handling the corrugated carton body 100, effectively avoiding accidental loss of the support base 200.

[0029] It should be noted that in the above embodiments, the support base 200 and the corrugated carton body 100 adopt an adhesive connection structure. The support base 200 and the corrugated carton body 100 can also adopt other connection structures. For example, in other embodiments of the present invention, the lower part of the corrugated carton body 100 and the mounting groove 210 are interference fit. When the lower part of the corrugated carton body 100 is embedded in the mounting groove 210, the mounting groove 210 clamps the lower part of the corrugated carton body 100, thereby making the support base 200 and the corrugated carton body 100 firmly connected together.

[0030] To reduce the weight of the support base 200, in some embodiments of the present invention, the bottom of the support base 200 is provided with a plurality of perforated holes 230, which are arranged at intervals on the bottom wall of the mounting groove 210. In this embodiment, the support base 200 is a plastic bracket. By providing a plurality of perforated holes 230 at the bottom of the support base 200, the weight of the support base 200 can be reduced, and the material used to manufacture the support base 200 can be reduced, thereby reducing production costs.

[0031] In some embodiments of the present invention, the bottom surface of the support base 200 is provided with a plurality of threaded connection holes 240, and the upper part of each support leg 220 is provided with a threaded connecting rod 221 that can be threadedly connected to the threaded connection hole 240. When the plurality of support legs 220 are installed on the support base 200, the threaded connecting rods 221 of the plurality of support legs 220 are threadedly connected to the plurality of threaded connection holes 240 in a one-to-one correspondence. In this embodiment, the support legs 220 have a plurality of different length specifications. Therefore, the user can install support legs 220 of different lengths on the bottom of the support base 200 as needed, adjust the overall height of the support base 200, and thereby adjust the distance between the corrugated cardboard box body 100 placed on the support base 200 and the support surface, effectively preventing water accumulation on the support surface from contacting and soaking the bottom of the corrugated cardboard box body 100, and greatly improving the waterproof and moisture-proof performance of the corrugated cardboard box in this embodiment.

[0032] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
