Description

Technical Field

[0001] The utility model relates to a corner protector, in particular to a paper-plastic corner protector. Background Art

[0002] Corner protectors, as the name suggests, are used to protect corners or walls. They can be broadly categorized into three types: packaging corner protectors, decorative corner protectors, and architectural corner protectors. Packaging corner protectors are primarily used on product packaging to protect and support the product. They are primarily made of paper, plastic, or metals such as iron, copper, and aluminum. Plastic corner protectors are not easily degradable and are therefore not environmentally friendly, while metal corner protectors are expensive. Existing paper corner protectors are mostly designed as simple triangular shapes, which are still insufficient for product protection and support. Utility Model Content

[0003] Based on this, it is necessary to provide a paper-plastic corner protector to address the deficiencies in the prior art.

[0004] A paper-plastic corner protector is made of paper-plastic material, comprising a main body and folding parts arranged on the left and right sides of the main body, a folding line being arranged between the main body and the folding parts, and the folding parts being rotated and folded onto the main body along the folding line toward the back side of the main body. A receiving cavity is arranged on the front side end face of the main body, and a raised portion is formed on the back side of the main body corresponding to the position of the receiving cavity. A folding cavity is arranged on the front side end face of the folding part, and a folding groove is formed on the back side of the folding part corresponding to the position of the folding cavity. The folding grooves of the two folding parts are arranged correspondingly up and down, and the raised portion on the main body is embedded in the folding grooves of the two folding parts.

[0005] Furthermore, the folding groove of the folding portion is formed with a side edge, and the side edge is provided with an engaging slot and an engaging block. The side edges of the two folding portions engage with each other, and the engaging block and engaging slot on one folding portion are correspondingly engaged with the engaging slot and engaging block on the other folding portion.

[0006] Furthermore, a plurality of reinforcing protrusions are provided on the inner side of the folding cavity. The plurality of reinforcing protrusions are stacked in a stepped manner, and the plurality of reinforcing protrusions are all designed in a triangular structure.

[0007] Furthermore, the upper and lower side surfaces of the raised portion are both triangular in design, and the left and right side surfaces are both rectangular in design. The front side end surface of the folded portion is triangular in design.

[0008] Furthermore, the two groups of folding portions are integrally formed on the left and right sides of the main body, and the main body and the two folding portions are designed with rounded corners.

[0009] To sum up, the beneficial effects of the paper-plastic corner protector of the present invention are: by designing a foldable paper-plastic corner protector structure, the supporting strength of the corner protector is greatly improved, which greatly enhances the packaging protection effect of the product, and the foldable or unfoldable deformation structure is also more convenient for the storage and transportation of the corner protector itself; the corner protector adopts paper-plastic material, which not only further improves the firmness, but also is more environmentally friendly; the convex block structure design of the folding part can further enhance the overall structural strength of the corner protector; the engaging slot and engaging block of the folding part make the folding state of the folding part more stable; the utility model is highly practical and has strong promotion significance.

[0013] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0014] like Figures 1 to 3 As shown, the present invention provides a paper-plastic corner protector 100, which is made of paper-plastic material and includes a main body 10 and folding parts 20 arranged on the left and right sides of the main body 10. A folding line 30 is provided between the main body 10 and the folding part 20, and the folding part 20 is rotated and folded on the main body 10 along the folding line 30 toward the back side of the main body 10.

[0015] The main body 10 has a receiving cavity 11 formed on its front end surface, and a raised portion 12 formed on its back side at a position corresponding to the receiving cavity 11. The folding portion 20 has a folding cavity 21 formed on its front end surface, and a folding groove 22 formed on its back side at a position corresponding to the folding cavity 21. The folding grooves 22 of the two folding portions 20 are arranged in a corresponding manner, and the raised portions 12 on the main body 10 are fitted into the folding grooves 22 of the two folding portions 20.

[0016] Folding corner protectors can be folded and placed around the corners of the product being protected for stronger support and protection, or unfolded for easy stacking and storage, positively impacting production, transportation, and sales. Furthermore, paper-plastic corner protectors not only possess exceptional structural strength to provide support and protection, but are also more environmentally friendly and cost-effective.

[0017] The folding groove 22 of the folding portion 20 is formed with a side edge 23, and the side edge 23 is provided with an engaging groove 24 and an engaging block 25. The side edges 23 of the two folding portions 20 engage with each other, and the engaging block 25 and engaging groove 24 on one folding portion 20 are correspondingly engaged with the engaging groove 24 and engaging block 25 on the other folding portion 20. The design of the engaging groove 24 and engaging block 25 ensures that when the two sets of folding portions 20 are folded and engaged with the main body 10, the engagement between the engaging groove 24 and engaging block 25 strengthens the connection and fixation between the two sets of folding portions 20, thereby reducing the risk of the folding portions 20 accidentally unfolding on the corner guard when folded, thereby affecting the support and protection capabilities.

[0018] The inner side of the folding cavity 21 is also provided with a plurality of reinforcing protrusions 26. These reinforcing protrusions 26 are arranged in a stepped and triangular structure. The stepped reinforcing protrusions 26 provide greater support strength to the folding portion 20 and the entire paper-plastic corner protector 100, thereby enhancing its support and protection capabilities for the protected product.

[0019] The upper and lower sides of the raised portion 12 are triangular in design, while the left and right sides are rectangular in design. The front end surface of the folded portion 20 is triangular in design. This triangular structural stability significantly enhances the overall support strength of the paper-plastic corner protector 100, providing more reliable protection for the product being protected.

[0020] The two sets of folding portions 20 are integrally formed on the left and right sides of the main body 10, and both the main body 10 and the two folding portions 20 have rounded corners. The integrally formed paper-plastic corner protector 100 is not only easy to manufacture but also more reliable to use. The rounded corners of the paper-plastic corner protector 100 prevent scratches or punctures caused by sharp corners.

[0021] To sum up, the beneficial effects of the paper-plastic corner protector 100 of the present invention are: by designing a foldable paper-plastic corner protector 100 structure, the supporting strength of the corner protector is greatly improved, which greatly enhances the packaging protection effect of the product, and the foldable or unfoldable deformation structure is also more convenient for the storage and transportation of the corner protector itself; the corner protector is made of paper-plastic material, which not only further improves the firmness, but also is more environmentally friendly; the convex block structure design of the folding part 20 can further enhance the overall structural strength of the corner protector; the engaging slot 24 and the engaging block 25 of the folding part 20 make the folding state of the folding part 20 more stable; the utility model is highly practical and has strong promotion significance.

[0022] The above-described embodiment merely represents one embodiment of the utility model. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the utility model, and these modifications and improvements fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be determined by the appended claims.
