Description

Technical Field

[0001] This utility model relates to the field of packaging structure technology, and in particular to an integrated corrugated paper packaging structure. Background Technology

[0002] With the rapid development of e-commerce and logistics, the requirements for cushioning and impact resistance of packaging for high-value, fragile goods (such as electronic products and ceramic products) have significantly increased. Integrated corrugated cardboard packaging structures, due to their advantages such as environmentally friendly materials and simplified processes, are gradually becoming a replacement for traditional foam cushioning solutions. They achieve one-piece molding through die-cutting and creasing processes, effectively reducing material combinations and waste generation.

[0003] Currently, integrated corrugated cardboard packaging structures suffer from key technical defects. During the folding and forming process, the corrugations (corrugated core layer) of the corrugated cardboard are easily exposed at the structural edges and joints. The exposed corrugated edges have extremely low strength and are easily crushed or torn when subjected to external pressure or impact, directly causing the overall packaging structure to fail. This prevents the packaging from maintaining its designed cushioning performance and seriously affects the protection of high-value, fragile goods during transportation.

[0004] Therefore, there is an urgent need for integrated corrugated paper packaging structures to solve the above problems. Utility Model Content

In use, firstly, the first left and first right interlayer boards are folded upwards at a 90-degree angle relative to the front side panel, and the second left and second right interlayer boards are folded upwards at a 90-degree angle relative to the rear outer side panel. Then, the front side panel and the rear outer side panel are each folded upwards at a 90-degree angle relative to the bottom panel, forming a left protective layer and a right protective layer. Next, the two left flaps are folded 180 degrees relative to the left outer side panel and attached to the surface of the left outer side panel, and the two right flaps are folded 180 degrees relative to the right outer side panel and attached to the surface of the right outer side panel. Finally, the left and right outer side panels are each folded upwards at a 90-degree angle relative to the bottom panel, and the two left flaps are attached to the left protective layer.

The buffer housing is set in the receiving chamber to realize product buffering and shock absorption; finally, the top cover is folded downward 90 degrees relative to the front side panel to close the opening of the receiving chamber. In this integrated corrugated cardboard packaging structure, all edges and joints of the corrugated cardboard are in flat cardboard-to-surface contact, completely avoiding exposed corrugations and significantly enhancing the structural edge strength, compression resistance, and durability. Only one sheet of corrugated cardboard is required for die-cutting and creasing, eliminating the need for adhesives or other auxiliary materials, achieving one-piece molding and improving material utilization, production efficiency, and environmental friendliness. The unique folding interlocking design transforms a single sheet of cardboard into a stable three-dimensional structure with multiple layers of buffer walls. These layers support each other, forming a highly efficient mechanical load-bearing system that provides comprehensive protection for the products within the enclosure. Simultaneously, it simplifies the process, reduces material usage, and lowers overall costs. Users can quickly fold and shape the cardboard or flatten it for recycling, saving assembly and disassembly time and improving the user experience. Attached Figure Description

[0067] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0068] This utility model provides an integrated corrugated paper packaging structure, such as Figures 1-11 As shown, the integrated corrugated paper packaging structure includes a bottom plate 1 and a front side plate 2, a left outer side plate 31, a rear outer side plate 41 and a right outer side plate 51 that are connected to the bottom plate 1 in sequence around its perimeter.

[0069] The integrated corrugated cardboard packaging structure also includes a first left interlayer plate 32, a first right interlayer plate 52, a first left interlayer plate 32, and a first right interlayer plate 52. The first left interlayer plate 32 and the first right interlayer plate 52 are respectively connected to the opposite sides of the front side plate 2, and can both be folded upward 90 degrees relative to the front side plate 2. The second left interlayer plate 33 and the second right interlayer plate 53 are respectively connected to the opposite sides of the rear outer side plate 41, and can both be folded upward 90 degrees relative to the rear outer side plate 41. The front side plate 2 and the rear outer side plate 41 can both be folded upward 90 degrees relative to the bottom plate 1, so that the first left interlayer plate 32 and the second left interlayer plate 33 are bonded together to form a left protective layer, and the first right interlayer plate 52 and the second right interlayer plate 53 are bonded together to form a right protective layer.

[0070] The integrated corrugated cardboard packaging structure also includes two left flaps 34 and two right flaps 54. The two left flaps 34 are respectively connected to the opposite sides of the left outer panel 31, and can be folded 180 degrees relative to the left outer panel 31 and attached to the surface of the left outer panel 31. The two right flaps 54 are respectively connected to the opposite sides of the right outer panel 51, and can be folded 180 degrees relative to the right outer panel 51 and attached to the surface of the right outer panel 51. The left outer panel 31 and the right outer panel 51 can both be folded upward 90 degrees relative to the bottom plate 1 so that the two left flaps 34 are attached to one side of the left protective layer and the two right flaps 54 are attached to one side of the right protective layer.

[0071] The integrated corrugated cardboard packaging structure also includes a left inner side panel 35 and a right inner side panel 55. The left inner side panel 35 is connected to the side of the left outer side panel 31 that is away from the lower bottom panel 1, and can be folded 180 degrees relative to the left outer side panel 31 and attached to the other side surface of the left protective layer. The right inner side panel 55 is connected to the side of the right outer side panel 51 that is away from the lower bottom panel 1, and can be folded 180 degrees relative to the right outer side panel 51 and attached to the other side surface of the right protective layer.

[0072] The integrated corrugated cardboard packaging structure also includes a cushioning built-in part 6 and a rear inner side plate 42. On opposite sides of the rear inner side plate 42, one side is connected to the side of the rear outer side plate 41 that is away from the lower bottom plate 1, and the other side is connected to the cushioning built-in part 6. The cushioning built-in part 6 is formed by folding. The rear inner side plate 42 can be folded 180 degrees relative to the rear outer side plate 41 and fits against the rear outer side plate 41. The cushioning built-in part 6 can be folded upward 90 degrees relative to the rear inner side plate 42 so that the rear inner side plate 42 abuts against the end of the left inner side plate 35 and the end of the right inner side plate 55, and together with the front side plate 2, it forms a receiving chamber 100. The cushioning built-in part 6 is disposed in the receiving chamber 100 and is configured to cushion and reduce shock for the product in the receiving chamber 100.

[0073] The integrated corrugated cardboard packaging structure also includes a top cover, which is connected to the side of the front side panel 2 opposite to the bottom panel 1 and can be folded down 90 degrees relative to the front side panel 2 to close the upper opening of the receiving chamber 100.

[0074] like Figures 2-11 As shown, the folding process of this integrated corrugated cardboard packaging structure is roughly as follows:

[0075] like Figure 2 As shown, the first left interlayer plate 32 and the first right interlayer plate 52 are first folded upwards by 90 degrees relative to the front side plate 2, and the second left interlayer plate 33 and the second right interlayer plate 53 are folded upwards by 90 degrees relative to the rear outer side plate 41.

[0076] like Figure 3 As shown, the front side panel 2 and the rear outer side panel 41 are then folded upwards by 90 degrees relative to the bottom panel 1 to form a left protective layer and a right protective layer.

[0077] like Figure 4 As shown, the two left flaps 34 are then folded 180 degrees relative to the left outer panel 31 and attached to the surface of the left outer panel 31, and the two right flaps 54 are folded 180 degrees relative to the right outer panel 51 and attached to the surface of the right outer panel 51.

[0078] like Figure 5 As shown, the left outer panel 31 and the right outer panel 51 are then folded upwards by 90 degrees relative to the bottom panel 1, with the two left flaps 34 adhering to one side of the left protective layer and the two right flaps 54 adhering to one side of the right protective layer.

[0079] like Figure 6 As shown, the left inner panel 35 is folded 180 degrees relative to the left outer panel 31 and adheres to the other side surface of the left protective layer, and the right inner panel 55 is folded 180 degrees relative to the right outer panel 51 and adheres to the other side surface of the right protective layer.

[0080] like Figures 7-9 As shown, the buffer built-in part 6 is folded into shape, and then the rear inner side plate 42 is folded 180 degrees relative to the rear outer side plate 41. The buffer built-in part 6 is folded upward 90 degrees relative to the rear inner side plate 42, so that the rear inner side plate 42 abuts against the ends of the left inner side plate 35 and the right inner side plate 55, and together with the front side plate 2, it encloses the receiving cavity 100. The buffer built-in part 6 is set in the receiving cavity 100 to realize product buffering and shock absorption.

[0081] like Figures 10-11 As shown, the top cover is finally folded down 90 degrees relative to the front side panel 2 to close the opening of the receiving chamber 100.

[0082] In this integrated corrugated cardboard packaging structure, all edges and joints of the corrugated cardboard are in flat contact, completely avoiding exposed corrugations and significantly enhancing the structural edge strength, compression resistance, and durability. Only one sheet of corrugated cardboard is required for die-cutting and creasing, eliminating the need for adhesives or other auxiliary materials, achieving one-piece molding and improving material utilization, production efficiency, and environmental friendliness. The unique folding interlocking design transforms a single sheet of cardboard into a stable three-dimensional structure with multiple layers of buffer walls. These layers support each other to form a highly efficient mechanical load-bearing system, providing comprehensive protection for products within a 100-cubic-meter cavity. Simultaneously, it simplifies the process, reduces material usage, and lowers overall costs. Users can quickly fold and shape the cardboard or flatten it for recycling, saving assembly and disassembly time and improving the user experience.

[0083] It is worth noting that "flat cardboard surface contact" means that when the integrated corrugated packaging structure is joined at the edges and laminated between layers, the flat layers of the cardboard on both sides are always in contact with each other, rather than exposing the corrugations of the core paper at the contact or edge positions. This avoids the problem of the corrugations being easily crushed or torn due to the lack of protection from the face paper.

[0084] like Figures 9-11 As shown, the upper cover includes an upper outer side plate 71 and an upper inner side plate 72. The upper outer side plate 71 is connected to the side of the front side plate 2 that is away from the lower bottom plate 1. The upper inner side plate 72 is connected to one side of the upper outer side plate 71. Two upper flaps 73 are respectively connected to the opposite sides of the upper inner side plate 72. Both can be folded 180 degrees relative to the upper inner side plate 72 and are parallel to the surface of the upper inner side plate 72. The upper inner side plate 72 can be folded 180 degrees relative to the upper outer side plate 71 and is parallel to the surface of the upper outer side plate 71 with a reserved gap, so that the two upper flaps 73 fit with the surface of the upper outer side plate 71 to form the upper cover. The top cover is formed by the folding of the upper outer side panel 71, the upper inner side panel 72 and the two upper flip panels 73. The upper inner side panel 72 is folded 180 degrees relative to the upper outer side panel 71 and is parallel and fitted with a gap. The two upper flip panels 73 are folded 180 degrees relative to the upper inner side panel 72 and are then fitted with the surface of the upper outer side panel 71. This not only achieves the integrated molding of the top cover and avoids the exposure of pits, but also enhances the pressure resistance and cushioning through the multi-layer structure and the reserved gap. It can more tightly seal the cavity 100 and improve the protection effect for the built-in products.

[0085] like Figures 9-11As shown, the integrated corrugated cardboard packaging structure also includes a tongue 81. The tongue 81 is connected to the side of the upper outer panel 71 opposite to the lower bottom plate 1. The connection between the rear outer panel 41 and the rear inner panel 42 is provided with a matching insertion hole 82. The tongue 81 can be inserted into the insertion hole 82 to achieve the closed and fixed design of the integrated corrugated cardboard packaging structure. The tongue 81 is connected to the side of the upper outer panel 71 opposite to the lower bottom plate 1, and the connection between the rear outer panel 41 and the rear inner panel 42 is provided with a matching insertion hole 82. The tongue 81 can be inserted into the insertion hole 82 to achieve the closed and fixed design of the packaging structure without the need for additional adhesives or fasteners, conforming to the environmentally friendly and efficient design of one-piece molding. At the same time, the cooperation between the tongue 81 and the insertion hole 82 can firmly lock the top cover, preventing the top cover from loosening due to vibration during transportation, ensuring the sealing of the containing chamber 100, further protecting the built-in product, and the structure is simple and easy to operate, improving ease of use.

[0086] like Figures 9-10 As shown, the upper inner side panel 72 has gripping openings 9 on both sides for fingers to insert and apply force to open the top cover. The gripping openings 9 on both sides of the upper inner side panel 72 solve the problem of lack of a point of force when opening integrated corrugated cardboard packaging, which is prone to structural damage due to forced tearing. This makes operation convenient and effortless. Furthermore, the gripping openings 9 only need to be processed simultaneously in the die-cutting process, requiring no additional processes or materials. This does not compromise the environmentally friendly and efficient characteristics of the packaging as a single piece of paper, nor does it affect the sealing and protection of the containing chamber 100, thus balancing practicality and structural integrity.

[0087] like Figures 7-9 As shown, the buffer built-in part 6 includes a bottom support plate 611, a first left support plate 621, a first right support plate 631, a first middle support plate 641, and a second middle support plate 642. The bottom support plate 611 is connected to the side of the rear inner side plate 42 opposite to the lower bottom plate 1. The first left support plate 621 is connected to one side of the bottom support plate 611 and can be folded downwards by 90 degrees relative to the bottom support plate 611. The first right support plate 631 and the first middle support plate 641 are both connected to the other side of the bottom support plate 611 and can be folded downwards by 90 degrees relative to the bottom support plate 611, so that the first right support plate 631 and the first middle support plate 641 are parallel to the folded first left support plate 621. The second middle support plate 642 is connected to the first middle support plate 641 and disconnected from the bottom support plate 611 and the first right support plate 631 to form a clearance opening 601. The second middle support plate 642 can be folded upwards by 90 degrees relative to the first middle support plate 641.

[0088] The buffer housing 6 also includes a first upper support plate 651, a second right support plate 632, a second upper support plate 652, and a second left support plate 622. The first upper support plate 651 is connected to the side of the first right support plate 631 that is away from the bottom support plate 611. The second right support plate 632 is connected to the side of the first upper support plate 651 that is away from the bottom support plate 611, and can be folded upwards by 90 degrees relative to the first upper support plate 651, parallel to the folded first right support plate 631. The second upper support plate 652 is connected to the side of the first left support plate 621 that is away from the bottom support plate 611. The second left support plate 622 is connected to the side of the second upper support plate 652 that is away from the bottom support plate 611, and can be folded upwards by 90 degrees relative to the second upper support plate 652, parallel to the folded first left support plate 621.

[0089] When the folded-down buffer housing 6 is placed in the receiving chamber 100, the bottom support plate 611 is attached to the lower bottom plate 1, the second left support plate 622 is attached to the left inner side plate 35, the second right support plate 632 is attached to the right inner side plate 55, and the second middle support plate 642 is parallel to the rear inner side plate 42. The buffer housing 6 is formed by the orderly folding of the support plates. When placed in the receiving chamber 100, the bottom support plate 611 is attached to the lower bottom plate 1, the second left support plate 622 and the second right support plate 632 are attached to the left inner side plate 35 and the right inner side plate 55 respectively, and the second middle support plate 642 is parallel to the rear inner side plate 42, forming a stable three-dimensional buffer structure. Furthermore, the recessed opening 601 can adapt to the product shape and has no exposed grooves throughout, providing all-around shock absorption protection for the built-in product while perfectly fitting the overall one-piece molding design, balancing environmental protection and structural stability.

[0090] like Figures 7-9 As shown, the folding and forming process of the buffer built-in part 6 is roughly as follows: First, the second middle support plate 642 is folded upwards by 90 degrees relative to the first middle support plate 641; then, the first left support plate 621, the first right support plate 631, and the first middle support plate 641 are folded downwards by 90 degrees relative to the bottom support plate 611, so that the three are parallel; the first upper support plate 651 remains horizontal, the second right support plate 632 is folded upwards by 90 degrees relative to the first upper support plate 651 and is parallel to the first right support plate 631, the second upper support plate 652 remains horizontal, and the second left support plate 622 is folded upwards by 90 degrees relative to the second upper support plate 652 and is parallel to the first left support plate 621; after the buffer built-in part 6 is formed, it is placed in the receiving chamber 100, the bottom support plate 611 is attached to the lower bottom plate 1, the second left support plate 622 is attached to the left inner side plate 35, the second right support plate 632 is attached to the right inner side plate 55, and the second middle support plate 642 is parallel to the rear inner side plate 42.

[0091] like Figure 7 and Figure 9As shown, both the first upper support plate 651 and the second upper support plate 652 are provided with perforations 603, which are used to insert a hand to adjust the position of the buffer housing 6 in the receiving chamber 100. The perforations 603 allow the hand to insert and adjust the position of the buffer housing 6 within the receiving chamber 100, solving the problem of difficulty in moving and calibrating the buffer housing 6 after it is placed in the chamber, making operation convenient and efficient. Furthermore, the perforations 603 only require simultaneous processing in the die-cutting process, without the need for additional processes or materials, and do not damage the three-dimensional support structure and the absence of exposed pits of the buffer housing 6, thus balancing practicality with protection and environmental protection.

[0092] like Figures 7-9 As shown, the bottom support plate 611 is a first L-shaped plate, and the first upper support plate 651 is a second L-shaped plate. The lengths of the right-angled sides of the first and second L-shaped plates are respectively equal. The second L-shaped plate is formed by rotating the first L-shaped plate 180 degrees. When the folded-in-place buffer housing 6 is placed in the receiving chamber 100, the first and second L-shaped plates are parallel to each other and correspond to each other at right-angled inflection points in space, with the long and short sides alternately connected to form a U-shape, with the recess 601 enclosed within it. On the one hand, the bottom support plate 611 and the first upper support plate 651, through the L-shaped structure and the 180-degree rotation adaptation design, significantly enhance the support strength and deformation resistance of the buffer housing 6. On the other hand, the precise enclosure of the recess 601 to fit the product does not damage the characteristic of no exposed pits and requires no additional structural assistance, perfectly matching the environmentally friendly and efficient design of one-piece molding, and improving the protective stability of the product.

[0093] like Figures 7-9 As shown, the widths of the first left support plate 621, the second left support plate 622, the first right support plate 631, and the second right support plate 632 are all equal. Furthermore, the extension lengths of the first middle support plate 641 and the second middle support plate 642 are adapted to the corresponding side dimensions of the first L-shaped plate and the second L-shaped plate, ensuring that the first L-shaped plate and the second L-shaped plate in the folded buffer housing 6 are parallel to each other. This precise alignment ensures that the first L-shaped plate and the second L-shaped plate are stably parallel after the buffer housing 6 is folded, guaranteeing a regular U-shaped structure and uniform support force. This avoids structural loosening or protective failure due to dimensional deviations, while eliminating the need for additional processes. This aligns with the environmentally friendly and efficient one-piece molding design, enhancing the reliability of protection for products within the housing chamber 100.

[0094] like Figures 7-9As shown, the first right support plate 631 is a third L-shaped plate. The straight side of one right-angled side of the third L-shaped plate is connected to the first upper support plate 651. On the connecting side with a right-angled inflection point formed by the intersection of two right-angled sides opposite to the straight side, one right-angled side is connected to the bottom support plate 611, and the other right-angled side is disconnected from the second middle support plate 642 to form a clearance opening 601. The two sides of the third L-shaped plate perpendicular to the extension direction of the straight side are the first free side and the second free side, respectively. The length of the first free side is less than the length of the second free side. When the folded buffer built-in part 6 is placed in the receiving chamber 100, the two sides of the second middle support plate 642 along its length extension direction abut against the lower bottom plate 1 and the first upper support plate 651, respectively. On the two sides of the second middle support plate 642 along its width direction, one side is connected to the first middle support plate 641, and the other side abuts against the first free side, so that the connecting side, the lower bottom plate 1, and the second middle support plate 642 together form a gas flow opening 602. On the one hand, the first right support plate 631 is designed as a third L-shaped plate, which, in conjunction with the disconnection design, forms a clearance opening 601 to accommodate the product and avoid interference. After folding, the second middle support plate 642 abuts against the lower base plate 1, the first upper support plate 651, and the third L-shaped plate, together forming a gas flow opening 602. This not only promotes air circulation within the containment chamber 100 but also naturally forms an additional air buffer channel and deformation energy absorption space, further enhancing the overall buffering and shock absorption performance. On the other hand, the gas flow opening 602 promotes air circulation within the containment chamber 100, preventing the product from becoming damp or overheated due to stuffiness. At the same time, this design does not damage the support structure of the internal buffer part 6 and its pitless exposed characteristics, meeting the environmentally friendly and efficient requirements of one-piece molding and improving the practicality of protection.

[0095] like Figure 1 and Figure 7 As shown, the right-angle connection on the side of the second support plate 642 opposite to the first support plate 641 is rounded to reduce airflow resistance in the gas flow port 602. On one hand, this effectively reduces airflow resistance in the gas flow port 602, allowing for smoother airflow inside and outside the containment chamber 100, preventing the product from becoming damp or overheating due to stuffiness. On the other hand, the rounded corners eliminate sharp right-angle edges, preventing damage to the cardboard edges during folding or use, without compromising the support structure and pit-free exposed characteristics of the buffer interior 6, aligning with the environmentally friendly and efficient one-piece molding design, and improving protective reliability and service life.
