Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to a packaging corner protection structure. Background Art

[0002] In the field of packaging and logistics, the safety and integrity of products are of vital importance. Especially during transportation and storage, the corners of products are more vulnerable to damage due to their structural characteristics. In order to protect these fragile areas, the traditional approach is to use foam plastics, bubble film or other similar cushioning materials. However, these materials are not only expensive, but also often produce difficult-to-degrade waste during use, which has an adverse impact on the environment.

[0003] In recent years, with the improvement of environmental awareness and the demand for sustainable development, the industry has been seeking more environmentally friendly, economical and efficient packaging solutions. Among them, paper packaging materials have attracted much attention due to their renewable, recyclable and biodegradable properties. However, the existing paper corner protection packaging structure often needs to be fixed with glue or other adhesives, which not only increases the complexity of the production process, but also affects the environmental friendliness of the packaging.

[0004] The present invention aims to solve the above problems and proposes a new type of cushioning corner protection packaging structure. The structure not only has excellent cushioning performance and can effectively protect the corners of the product from damage, but is also made of environmentally friendly materials and does not require the use of glue or other adhesives for fixing, thereby significantly improving the environmental protection of the packaging and production efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a packaging corner protection structure. The technical solution in the present application is described below:

[0006] A packaging corner protection structure, comprising:

[0008] Optionally, the continuous fracture lines include a first fracture line opened on the top end surface, a second fracture line opened on the second folding plate, and a third fracture line opened on the bottom end surface, one end of the first fracture line is connected to the anti-folding line on the first folding plate, and the other end is connected to the second fracture line, one end of the third fracture line is connected to the anti-folding line on the third folding plate, and the other end is connected to the second fracture line.

[0009] Optionally, the second fracture line is a “Z”-shaped fracture line.

[0010] Optionally, the second break line is composed of a first section, a second section and a third section, one end of the first section is connected to the first break line, and the other end is connected to the second section, one end of the third section is connected to the third break line, and the other end is connected to the second section, the first section is parallel to the third section, and the first section is perpendicular to the second section.

[0011] Optionally, the first fracture line and the second fracture line are inclined fracture lines, so that the formed fracture is an oblique fracture.

[0012] Optionally, the anti-folding line on the first folding plate is a tooth-shaped folding line.

[0013] Optionally, a notch is provided at the end of the anti-folding line on the first folding plate.

[0014] Optionally, the notch is arranged at an end of the anti-folding line that is not connected to the break line.

[0015] Optionally, the anti-folding line on the first folding plate is perpendicular to the first folding line, and the anti-folding line on the third folding plate is perpendicular to the third folding line.

[0017] It can be seen from the above technical solutions that this application has the following advantages:

[0018] Through the design of multiple folding plates and the top and bottom surfaces, the entire structure can form a compact and stable corner guard after folding. The top and bottom surfaces are respectively connected to the two sides of the second folding plate, which increases the stability of the overall structure.

[0019] Due to the structure of folding lines and continuous break lines, the packaging corner protector structure can be easily folded from a flat plate into a three-dimensional shape without the need for additional tools or adhesives. This greatly simplifies the packaging process and improves production efficiency.

[0020] Since the design of the folding plate and the top and bottom surfaces has a certain degree of flexibility, this packaging corner protection structure can adapt to products of different sizes and shapes. By adjusting the folding angle and position, protection of different corners can be achieved.

[0021] Through the combination of multiple folded panels and faces, the structure provides additional buffer space at the corners of the product, helping to absorb and disperse external impact forces, thereby protecting the product from damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The specific embodiments are described below:

[0034] The present application first provides an embodiment of a packaging corner protection structure, which includes: a first folding plate 01, a second folding plate 02, a third folding plate 03, a top end surface 04 and a bottom end surface 05; the first side of the top end surface 04 is connected to the first folding plate 01 through a first folding line 11, the second side of the top end surface 04 is connected to the second folding plate 02 through a second folding line 12, and the first side of the top end surface 04 is opposite to the second side of the top end surface 04; the first side of the bottom end surface 05 is connected to the second folding plate 02 through a third folding line 13, and the second side of the bottom end surface 05 is connected to the second folding plate 02 through a fourth folding line 14. The folding line 14 is connected to the third folding plate 03, the first side of the bottom end surface 05 is opposite to the second side of the bottom end surface 05, and the bottom end surface 05 and the top end surface 04 are respectively connected to the opposite sides of the second folding plate 02; the first folding plate 01 and the third folding plate 03 are respectively provided with colinear anti-folding lines 15, and the bottom end surface 05, the top end surface 04 and the second folding plate 02 are provided with continuous break lines 16, one end of the break line 16 is connected to the anti-folding line 15 on the first folding plate 01, and the other end is connected to the anti-folding line 15 on the third folding plate 03.

[0035] First, some nouns in this embodiment are explained in detail:

[0036] Break line 16: In this embodiment, the break line 16 is actually a pre-set cutting line, which is located on a specific panel (such as the bottom end surface 05, the top end surface 04 and the second folding plate 02) of the packaging corner protection structure and plays a role in guiding and forming the cutting edge during the folding process.

[0037] The main function of the break line 16 is to form a cutout after folding, and the cutout enables the packaging corner protection structure to be separated or disconnected at a specific position, so as to better adapt to the shape of the product and provide necessary protection. In this embodiment, through the formation of the cutout, the packaging corner protection can be more flexible around the corners of the product and provide additional buffer space when needed.

[0038] Folding lines: In this embodiment, folding lines refer to lines pre-set on each panel of the packaging corner protector structure (such as the first folding plate 01, the second folding plate 02, the third folding plate 03, the top end surface 04 and the bottom end surface 05). These lines are used to guide where the panels are folded to facilitate the transformation from a flat state to a three-dimensional packaging corner protector structure.

[0039] The main function of folding lines is to achieve the transformation of the packaging corner structure from flat to three-dimensional. They can exist in the form of physical indentations to provide operators with clear folding directions and positions. During the folding process, folding along these lines can ensure the consistency and stability of the structure.

[0040] In an embodiment, the folding line may be a groove line formed by pressing a creasing machine on a material such as cardboard.

[0041] This embodiment provides a packaging corner protection structure, which is mainly used to protect products (especially products with edges and corners) from damage during transportation and storage. The structure mainly includes five parts: a first folding plate 01, a second folding plate 02, a third folding plate 03, a top end surface 04 and a bottom end surface 05.

[0042] The first folding plate 01, the second folding plate 02, and the third folding plate 03: These three plates constitute the main support and protection part of the packaging corner protection structure. They can be flat sheets made of cardboard, plastic or other suitable materials, with sufficient rigidity and toughness to protect the product.

[0043] Top surface 04 and bottom surface 05: Top surface 04 and bottom surface 05 are respectively connected to first folding plate 01, second folding plate 02 and third folding plate 03, forming the upper and lower boundaries of the packaging corner protector. These two surfaces can be rectangular or other shapes suitable for the shape of the product.

[0044] The first side of the top end surface 04 is connected to the first folding plate 01 through a first folding line 11. The folding line allows the top end surface 04 to rotate freely at a certain angle on the first folding plate 01, so as to facilitate folding and unfolding.

[0045] The second side of the top end surface 04 is connected to the second folding plate 02 via a second folding line 12, forming a part of the side surface of the packaging corner protector.

[0046] Similarly, the first side of the bottom end surface 05 is connected to the second folding plate 02 via the third folding line 13, and the second side is connected to the third folding plate 03 via the fourth folding line 14. In this way, the bottom end surface 05 and the top end surface 04 are respectively located on both sides of the second folding plate 02, making the entire packaging corner protection structure more stable.

[0047] After folding, the top end face 04 and the bottom end face 05 become the upper and lower parallel end faces of the corner protection structure. The first folding plate 01 will overlap with the third folding plate 03 to form the inner side face of the corner protection structure, and the second folding plate 02 is the outer side face.

[0048] Anti-folding line 15 and break line 16: The first folding plate 01 and the third folding plate 03 are provided with a colinear anti-folding line 15. The anti-folding line 15 is to allow the two plates to be folded in the opposite direction, thereby forming a corner guard of a certain angle.

[0049] A continuous break line 16 is provided on the bottom end surface 05, the top end surface 04 and the second folding plate 02. The break line 16 is a tangent line, which makes the folding operation easier and more accurate. One end of the break line 16 is connected to the anti-folding line 15 on the first folding plate 01, and the other end is connected to the anti-folding line 15 on the third folding plate 03, so that when folded along the anti-folding line 15, the corner protection structure forms a break along the break line 16.

[0050] When the packaging corner protector needs to be used, the various parts can be folded into place according to the guidance of the folding line and the break line 16 to form a three-dimensional protective structure. This structure can not only adapt to products of different shapes and sizes, but also provide stable support and cushioning protection to reduce vibration and impact of the product during transportation and storage. If the material is cardboard or other recyclable materials, the entire packaging corner protector is not only practical but also environmentally friendly.

[0051] Through the above design, the packaging corner protection structure embodiment effectively solves the shortcomings of traditional corner protection structures in terms of material usage, environmental protection and ease of use, and provides a more economical, environmentally friendly and efficient solution.

[0052] In an optional embodiment, the continuous fracture line 16 includes a first fracture line 161 opened on the top end surface 04, a second fracture line 162 opened on the second folding plate 02, and a third fracture line 163 opened on the bottom end surface 05, one end of the first fracture line 161 is connected to the anti-folding line 15 on the first folding plate 01, and the other end is connected to the second fracture line 162, one end of the third fracture line 163 is connected to the anti-folding line 15 on the third folding plate 03, and the other end is connected to the second fracture line 162.

[0053] This optional embodiment provides a specific structure of a packaging corner protection structure, which includes: a first folding panel 01, a second folding panel 02, a third folding panel 03, a top end surface 04 and a bottom end surface 05. These panels are interconnected by folding lines and break lines 16 to form a three-dimensional protection structure.

[0054] This embodiment includes a series of continuous break lines 16, which are arranged on different panels of the packaging corner protector to achieve a smoother and more accurate folding process.

[0055] First break line 161: It is opened on the top surface 04. One end of this break line 16 is closely connected with the reverse folding line 15 on the first folding plate 01, and the other end is connected with the second break line 162 opened on the second folding plate 02. The existence of the first break line 161 allows the top surface 04 to accurately form a cut at the break line 16 when folding.

[0056] The second break line 162 is located on the second folding plate 02. One end of this break line 16 is connected to the first break line 161, and the other end is connected to the third break line 163 opened on the bottom end surface 05. The existence of the second break line 162 allows the second folding plate 02 to form a cut at the second break line 162 when folded along the reverse folding line 15, so that the entire structure can be folded into a corner protection structure.

[0057] The third break line 163 is formed on the bottom end surface 05. One end of the break line 16 is connected to the reverse folding line 15 on the third folding plate 03, and the other end is connected to the second break line 162. The design of the third break line 163 enables the bottom end surface 05 to form a tight fit with the third folding plate 03 and the second folding plate 02 when folded, and a cut is formed at the break line 16.

[0058] In order to more clearly show the distribution of each fracture line 16 in this embodiment, please refer to Figure 2 , Figure 2 The folded corner protection structure forms continuous cutouts at each cutout line 16 .

[0059] In a specific embodiment, the second break line 162 is a “Z”-shaped break line 16 .

[0060] This specific embodiment provides a special design of a packaging corner protection structure, wherein the second break line 162 is designed to be "Z" shaped. In this embodiment, the second break line 162 is composed of a plurality of straight line segments, which are arranged in a "Z" shape. The advantage of the "Z" shaped break line 16 is that after folding, the two cut surfaces of the cut can abut against each other to a certain extent, thereby preventing the corner protection structure from rebounding.

[0061] In practice, the "Z"-shaped fracture line 16 can have various forms. A specific embodiment is provided in the present application, that is, the second fracture line 162 is composed of a first section 001, a second section 002 and a third section 003, one end of the first section 001 is connected to the first fracture line 161, and the other end is connected to the second section 002, one end of the third section 003 is connected to the third fracture line 163, and the other end is connected to the second section 002, the first section 001 is parallel to the third section 003, and the first section 001 is perpendicular to the second section 002.

[0062] In this embodiment, the second break line 162 is composed of three straight line segments, forming a specific "Z" shape.

[0063] The first section 001: One end of the first section 001 is closely connected to the first break line 161 opened on the top surface 04. The other end is vertically connected to the second section 002 to form a right-angle turn.

[0064] The second section 002: The second section 002 is located in the middle of the "Z" shape, and is vertically connected to the first section 001 and the third section 003. This design increases the length of the break line 16, providing additional stability and flexibility.

[0065] The third section 003: One end of the third section 003 is closely connected to the third break line 163 opened on the bottom end surface 05. The other end is vertically connected to the second section 002 to form another right-angle turn. The third section 003 is parallel to the first section 001, ensuring the symmetry and stability of the packaging corner protection structure.

[0066] The break line 16 of this embodiment forms two right angles at the cut portion after folding, and these two right angles can abut against each other to improve stability.

[0067] In an optional embodiment, the first fracture line 161 and the second fracture line 162 are inclined fracture lines 16, so that the formed fracture is an oblique fracture.

[0068] In this embodiment, the first break line 161 and the second break line 162 are designed as inclined break lines 16, wherein the first break line 161 opened on the top surface 04 is designed as an inclined line. This inclined design enables the top surface 04 to be more smoothly connected with the first folding plate 01 and the second folding plate 02 when folded, while increasing the stability of the structure. Similarly, the second break line 162 opened on the second folding plate 02 is also an inclined line. This inclined second break line 162 is connected with the first break line 161 and the third break line 163 to form a continuous oblique support structure. This structure has better dispersion and resistance capabilities when subjected to external pressure.

[0069] In an optional embodiment, the anti-folding line 15 on the first folding plate 01 is a tooth-shaped folding line.

[0070] Application of the serrated anti-folding line 15 on the first folding plate 01 and analysis of its effect

[0071] In this embodiment, the anti-folding line 15 on the first folding plate 01 is specially designed to be tooth-shaped, and this design shows significant advantages in practical applications. The toothed anti-folding line 15 is similar in shape to a sawtooth or a spaced dotted line. This non-traditional folding line design brings multiple benefits to the folding plate.

[0072] When the corner guard structure is folded and formed, the first folding plate 01 is located on the outside of the folded corner, which causes the first folding plate 01 to be subjected to greater stress during the folding process. In this case, the traditional straight folding line may cause the folding plate to rebound greatly when folded, affecting the accuracy and stability of the folding. The design of the serrated anti-folding line 15, through its unique serrations or dotted line intervals, can effectively disperse and eliminate part of the stress during the folding process. This stress dispersion mechanism makes the first folding plate 01 smoother when folding and reduces the possibility of rebound.

[0073] Since the toothed anti-folding line 15 can eliminate part of the stress, the deformation of the first folding plate 01 during the folding process is more controllable. The folded structure thus has higher precision and stability. This is particularly important for corner protection structures that require precise folding and long-term folding.

[0074] The serrated anti-fold line 15 design also helps extend the service life of the corner guard structure by reducing springback and improving folding accuracy. Traditional straight fold lines may suffer fatigue fracture under long-term stress, while the serrated anti-fold line 15 reduces this risk by dispersing the stress.

[0075] In an optional embodiment, a notch 06 is provided at the end of the anti-folding line 15 on the first folding plate 01 .

[0076] Specifically, the notch position 06 is disposed at an end of the reverse folding line 15 that is not connected to the break line 16 .

[0077] In this optional embodiment, a notch 06 is provided at the end of the anti-folding line 15, and the notch 06 may be located at the end that is not connected to the break line 16. This means that when the folding plate is folded, the notch 06 will not be affected by the break line 16, thereby ensuring smooth folding.

[0078] During the folding process, the material will produce stress concentration near the folding line. By setting the notch position 06, this part of the stress can be effectively released to prevent the material from cracking or breaking during the folding process.

[0079] The notch 06 can also guide the folding direction. When folding, the material will naturally bend along the direction of the notch 06, thereby ensuring the accuracy and consistency of the folding. In addition to its functional role, the design of the notch 06 can also enhance the aesthetics of the folding plate to a certain extent. Through a reasonable design of the notch 06, the folded structure can be made neater and more beautiful. By setting the notch 06 at the end of the anti-folding line 15 on the first folding plate 01, the folding performance and service life of the folding plate can be effectively improved, while enhancing its aesthetics and practicality. This design has wide applicability and promotion value in practical applications.

[0080] In an optional embodiment, the anti-folding line 15 on the first folding plate 01 is perpendicular to the first folding line 11 , and the anti-folding line 15 on the third folding plate 03 is perpendicular to the third folding line 13 .

[0081] The corner protection structure provided in the present application can be used to protect corners of various shapes and angles. For example, when the corner of the product is 90 degrees, the anti-folding line 15 on the first folding plate 01 is perpendicular to the first folding line 11, which means that after folding along the anti-folding line 15 into the corner protection, the opposite side line can be made perpendicular to the corner plane. Of course, it can also be designed to other angles. For example, the anti-folding line 15 on the first folding plate 01 has a certain angle with the first folding line 11, which will form an inclined corner side line after folding.

[0082] The corner protection structure provided by the present application can be used to protect corners of various shapes and angles. Specifically, when the corner of the product is 90 degrees, the reverse folding line 15 on the first folding plate 01 is perpendicular to the first folding line 11, and the reverse folding line 15 on the third folding plate 03 is also perpendicular to the third folding line 13. This design ensures that the folded corner protection structure can fit tightly to the right-angle edge of the product and provide stable protection.

[0083] When the corners of the product are at a standard 90-degree right angle, the first folding plate 01 and the third folding plate 03 of the corner protection structure can be folded along their respective vertical reverse folding lines 15 to form a right-angled corner protection that matches the corners of the product. This design ensures that the corner protection structure can fit tightly to the corners of the product after folding, providing effective impact absorption and protection to prevent the product from being damaged during transportation or storage.

[0084] In addition to the protection of 90-degree angles, the design of the corner protection structure also allows for the protection of corners at other angles. For example, the anti-folding line 15 on the first folding plate 01 and the first folding line 11 can be designed to have a certain angle, so as to form an inclined corner edge line after folding. This flexibility enables the corner protection structure to adapt to product corners of various shapes and angles, providing customized protection solutions for different types of products.

[0085] In an optional embodiment, the first folding line 11 , the second folding line 12 , the third folding line 13 and the fourth folding line 14 are parallel to each other.

[0086] In an optional embodiment, the design of the corner protector structure takes into account the parallel relationship between the folding lines and the size consistency of each part after folding. Specifically, the first folding line 11, the second folding line 12, the third folding line 13 and the fourth folding line 14 are parallel to each other. This design ensures that the corner protector structure obtained after folding presents a rectangular shape as a whole, and the distance between the top end surface 04 and the bottom end surface 05 (i.e., the height of the corner protector structure) is always consistent.

[0087] In order to further realize the rationality of the corner protection structure, in a preferred embodiment, the folded first folding plate 01 and the third folding plate 03 overlap each other. In order to ensure the consistency of the size and thickness of the entire corner protection structure, the height of the first folding plate 01 (the distance from the first folding line 11 to the edge of the first folding plate 01) and the height of the third folding plate 03 (the distance from the fourth folding line 14 to the edge of the third folding plate 03) are the same. At the same time, the height of the second folding plate 02 (the distance from the second folding line 12 to the third folding line 13) is also consistent with the two.

[0088] In addition, in order to make the upper and lower thicknesses of the corner guard structure consistent, the width of the top end surface 04 (i.e., the distance between the first folding line 11 and the second folding line 12) is also equal to the width of the bottom end surface 05 (i.e., the distance between the third folding line 13 and the fourth folding line 14).

[0089] This design not only ensures the consistency of shape and size of the corner guard structure after folding, but also improves its structural stability and aesthetics. At the same time, this size consistency design also simplifies the manufacturing process and reduces production costs.

[0090] In practical applications, this corner protection structure can be widely used in various scenarios where corners need to be protected, such as furniture, packaging boxes, display racks, etc. By adjusting the position and spacing of the folding lines, the corner protection structure can also be customized to adapt to products of different sizes and shapes to meet the needs of different customers.

[0091] It should be noted that the above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
