Abstract
Description
Technical Field
[0001] This utility model relates to the field of corner protectors, and in particular to a waterproof corner protector for paper products. Background Technology
[0002] Paper corner protectors, also known as edge boards, are one of the most popular packaging products internationally, used to replace wooden packaging and other bulky packaging methods. They are characterized by low price, light weight, sturdiness, and compliance with environmental protection requirements. Also known as paper corner wraps, corner protector cardboard, edge boards, corner paper, or paper angle steel, they are made from yarn tube paper and kraft paper through a complete set of corner protector machines. Both ends are smooth and flat, without obvious burrs, and perpendicular to each other. They can replace wood and are 100% recyclable, making them one of the ideal new green packaging materials.
[0003] A search revealed a paper corner protector (publication number CN214266962U) comprising an L-shaped paper substrate, two layers of yarn tube paper, two layers of kraft paper, and two layers of compression-resistant layers; the two layers of yarn tube paper are respectively fixedly disposed on both sides of the L-shaped paper substrate, the two layers of kraft paper are respectively fixedly disposed on the outer side walls of the two layers of yarn tube paper, and the two layers of compression-resistant layers are respectively fixedly disposed on the outer side walls of the two layers of kraft paper.
[0004] Based on the aforementioned patent, the L-shaped paper substrate increases the support strength within the paper corner protectors, preventing them from easily deforming. Both sides of the L-shaped paper substrate are fixedly fitted with yarn tube paper, kraft paper, and a compression-resistant layer. The yarn tube paper has a smooth and uniform surface and good water resistance. The kraft paper and compression-resistant layer further increase the support strength of the corner protectors, making them less prone to deformation during use. However, the lack of cushioning material inside the honeycomb cardboard means it is easily damaged by bumps in the packaging box, affecting the normal use of the corner protectors. Furthermore, while a waterproof layer is only provided to the L-shaped paper substrate, its open perimeter allows moisture from the air to easily penetrate the honeycomb cardboard in humid environments, affecting the load-bearing capacity of the paper corner protectors. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waterproof corner protector for paper products, which aims to improve the problem that honeycomb cardboard cannot be waterproofed and that paper corner protectors themselves have low protection.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0033] Reference Figure 1-5 An embodiment of this utility model provides a waterproof corner protector for paper products, comprising a honeycomb base plate 1, a honeycomb side plate 2 on one side of the honeycomb base plate 1, a plurality of first grooves 3 on the top of the honeycomb side plate 2, a second groove 4 on the top of the honeycomb base plate 1, spring sheets 5 inside both the first grooves 3 and the second grooves 4, substrates 6 on both sides of the honeycomb side plate 2 and the honeycomb base plate 1, a first plastic edge seal 7 on one side of the honeycomb base plate 1, a second plastic edge seal 8 on the top of the honeycomb side plate 2, two waterproof mechanisms on both sides of the substrates 6, and waterproof layers 9 on both sides of the substrates 6, the waterproof layers 9 being soft plastic films.
[0034] Specifically, by opening several grooves on one side of the honeycomb base plate 1 and the honeycomb side plate 2, and setting spring sheets 5 inside the grooves, when the honeycomb side plate 2 is subjected to pressure, the pressure of the honeycomb base plate 1 can be shared by the operation of the spring sheets 5, thereby providing a certain buffer protection for the honeycomb base plate 1. The material of the substrate 6 is solid cardboard, and the first plastic sealing edge 7 and the second plastic sealing edge 8 are soft plastics that can be deformed to a certain extent.
[0035] The waterproof mechanism includes a waterproof plate 11 rotatably connected to both sides of the substrate 6. A connecting plate 12 is rotatably connected to one side of the waterproof plate 11. The waterproof plate 11 and the connecting plate 12 are both made of soft plastic. A first hook and loop fastener 13 is provided on one side of the connecting plate 12. Two second hook and loop fasteners 14 are provided on the top of the honeycomb bottom plate 1. Two third hook and loop fasteners 15 are provided on one side of the honeycomb side plate 2. The first hook and loop fastener 13 is adapted to the second hook and loop fasteners 14 and the third hook and loop fasteners 15 respectively.
[0036] Specifically, the first plastic edge sealing 7, the second plastic edge sealing 8, the waterproof layer 9, and the waterproof board 11 can isolate water in the air, preventing water in the air from entering the honeycomb base plate 1 and the honeycomb side plate 2 and affecting its load-bearing strength.
[0037] The bottom of the honeycomb base plate 1 is provided with an anti-slip rubber pad 10. The honeycomb base plate 1 and the honeycomb side plate 2 are perpendicular to each other. By providing the anti-slip rubber pad 10, the phenomenon of slippage is prevented when protecting the corners of heavy objects.
[0038] Working principle: Several grooves are opened on one side of the honeycomb base plate 1 and the honeycomb side plate 2, and spring sheets 5 are set inside the grooves. When the honeycomb side plate 2 is subjected to pressure, the spring sheets 5 can share the pressure of the honeycomb base plate 1, thereby providing a certain buffer protection for the honeycomb base plate 1. The first plastic sealing edge 7, the second plastic sealing edge 8, the waterproof layer 9, and the waterproof plate 11 can isolate water in the air and prevent water in the air from entering the honeycomb base plate 1 and the honeycomb side plate 2 and affecting its load-bearing strength.
[0039] When it is necessary to replace the damaged spring piece 5 in the first groove 3 or the second groove 4, separate the first hook and loop fastener 13 on the waterproof plate 11 from the second hook and loop fastener 14 and the third hook and loop fastener 15 respectively, release the waterproof plate 11 from the fixation, thereby releasing the fixation between the substrate 6 and the honeycomb base plate 1 and the honeycomb side plate 2. Then, open the substrate 6 at a certain angle, take out the damaged spring piece 5 in the first groove 3 or the second groove 4, and replace it with a new spring piece 5. After the replacement is completed, press the substrate 6 tightly against the honeycomb base plate 1 and the honeycomb side plate 2, and then fix the first hook and loop fastener 13 on the waterproof plate 11 to the second hook and loop fastener 14 and the third hook and loop fastener 15 respectively, thereby fixing the substrate 6 and completing the replacement of the spring piece 5.
