Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a multi-faceted protective inner tray for packaging boxes and a packaging box. Background Technology

[0002] In today's business world, product packaging plays a crucial role. It not only fulfills the basic function of protecting products from environmental damage but also influences the product's presentation and brand image. For many industries, such as electronics, precision instruments, handicrafts, and food, products are often fragile and easily damaged during transportation and storage due to collisions, compression, and other external forces, resulting in economic losses. Therefore, providing effective protective packaging for these products has become an urgent problem to be solved.

[0003] Currently, most common packaging methods on the market use traditional filler materials such as foam particles, bubble wrap, and paper scraps to wrap the product and provide cushioning. However, these traditional packaging methods have many drawbacks. On the one hand, foam particles and other filler materials are difficult to secure the product, making it prone to shifting during transportation and resulting in poor protection. On the other hand, these materials generate a large amount of waste after unpacking, which is difficult to recycle and does not meet environmental protection requirements. In addition, traditional packaging methods lack effective consideration for product presentation; often, after opening the package, the product is not presented to the consumer in a good condition.

[0004] As consumers increasingly demand higher product quality and a superior packaging experience, the market's need for packaging solutions with better protective performance and display effects is becoming increasingly urgent. While some existing packaging inserts can provide some degree of product fixation and protection, their simple structures often offer only limited protection, failing to provide comprehensive and effective protection for multiple aspects of the product. For example, some inserts only protect the bottom and sides of the product, lacking effective protection for the top or other critical areas, leaving the product vulnerable to damage from impacts from different directions. Furthermore, some inserts are complex to assemble and use, increasing packaging costs and time.

[0005] For example, Chinese utility model patent CN215324464U discloses a paper inner tray structure and packaging box. This paper inner tray structure mainly consists of a bottom tray for supporting the bottom of the product, side trays disposed on the bottom tray for supporting the opposite sides of the product, side trays with contact surfaces for limiting the opposite sides of the product, and a storage area. It can only protect the two sides of the product and cannot provide multi-sided protection.

[0006] In conclusion, existing packaging technologies and inner tray structures have many shortcomings in terms of protective performance, display effect, adaptability, and environmental friendliness, failing to meet the market's demand for high-quality packaging. Therefore, developing a packaging inner tray with multi-faceted protective functions and easy operation is of significant practical importance. Utility Model Content

[0007] This utility model aims to solve many problems existing in current packaging technology and inner tray structures. Specifically, it addresses the shortcomings of existing packaging inner trays, such as limited protective surface and complex assembly operations. It provides a multi-faceted protective inner tray and packaging box with multi-faceted protection functions and easy operation, to meet the market demand for high-quality packaging, ensuring that products are not damaged during transportation, storage, and display, and are presented to consumers in good condition.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-faceted protective inner tray for a packaging box includes a one-piece molded sheet-like body, the body being provided with fold lines to divide the body into multiple bendable portions; the bendable portions include: A first panel, configured to support the bottom of an item, the first panel being configured as a first protective surface; A second panel is disposed at one end of the first panel in the vertical direction, and a first zigzag line is formed between the second panel and the first panel; and A third panel is disposed at both ends of the second panel in the horizontal direction, and a second fold line is disposed between the third panel and the second panel; The second panel and the third panel are bent along the first fold line and the second fold line respectively to form a second protective surface and a third protective surface for protecting the item. The first protective surface, the second protective surface and the third protective surface together define a storage space for placing the item to protect the item from damage.

[0009] Furthermore, the first panel has first support plates disposed at both ends in the lateral direction, and a third fold line is disposed between the first panel and the first support plates. The first support plates are bent along the third fold line to form a support portion supporting the first panel.

[0010] Furthermore, the first panel is provided with a fixing plate for fixing the first support plate at one end in the longitudinal direction away from the second panel, so that the first panel can stably support the item.

[0011] Furthermore, the fixing plate is provided with an insertion hole for the first support plate to be inserted.

[0012] Furthermore, a gap is provided between the first panel and the third panel to facilitate the bending of the third panel along the second fold line.

[0013] Furthermore, each of the two third panels is provided with a second support plate at the end away from the second panel in the lateral direction, and a fourth fold line is provided between the second support plate and the second panel. The second support plate is bent along the fourth fold line to support the third protective surface formed by the third panel.

[0014] Furthermore, a third support plate is disposed at the end of the third panel away from the first panel in the longitudinal direction, and a fifth fold line is disposed between the third support plate and the third panel. The third support plate is bent along the fifth fold line to support the third protective surface formed by the third panel.

[0015] Furthermore, the free end of the third support plate is bent in a direction parallel to the third protective surface, forming a clamping space with the third protective surface to clamp and fix the second support plate, preventing the second support plate from shifting.

[0016] Furthermore, the end of the storage space opposite to the second panel is configured to be open to facilitate the display of the items.

[0017] A packaging box includes a box body, wherein an inner tray for protecting an item is disposed within the box body; the inner tray includes any of the multi-faceted protective inner trays described above. The storage space of the multi-faceted protective inner tray is adapted to the shape of the item to be packaged, and the outer wall of the multi-faceted protective inner tray is fitted or gap-fitted with the inner wall of the box cavity.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model's multi-faceted protective inner tray for packaging boxes achieves multi-faceted protection for products through a unique structural design. The first panel serves as the first protective surface, supporting the bottom of the item; the second panel is bent along the first fold line to form the second protective surface; and the third panel is bent along the second fold line to form the third protective surface. These three panels together define the storage space, encompassing multiple sides of the product within the protection scope. Compared to traditional inner trays that only protect the bottom and some sides of the product, this inner tray can more comprehensively resist collisions and pressure from different directions, effectively reducing the risk of damage to the product due to external forces during transportation and storage. It provides all-round safety protection for the product, and is especially suitable for electronic products, precision instruments, and other products with high protection requirements.

[0019] This inner tray incorporates multiple auxiliary support structures to further enhance its stability and product support capabilities. The first support plates at both ends of the first panel are bent along the third fold line to form support sections, providing additional support for the first panel. The fixing plate at the end furthest from the second panel in the longitudinal direction is equipped with insertion holes to secure the first support plate, ensuring stable support of the item by the first panel. Simultaneously, the second support plates at both ends of the third panel are bent along the fourth fold line, and the third support plate at the end furthest from the first panel in the longitudinal direction is bent along the fifth fold line, both effectively supporting the third protective surface. Furthermore, the clamping space formed by the bending of the third support plate in a direction parallel to the third protective surface secures the second support plate, preventing it from shifting. These auxiliary support structures work together to tightly connect all parts of the inner tray, forming a stable whole, greatly enhancing the inner tray's support stability for the product and preventing the product from shaking inside the packaging.

[0020] In terms of operation, the gap design between the first and third panels makes it easier and faster to bend the third panel along the second fold line, simplifying the assembly process of the inner tray and reducing packaging costs and time. For packaging personnel, the assembly of the inner tray and placement of the product can be completed quickly without complicated operating steps, improving packaging efficiency. Regarding the display effect, the end of the storage space opposite the second panel is configured as an open state, allowing consumers to directly see the full appearance of the product after opening the box, presenting the product in an attractive manner. This design not only enhances the product's display effect and increases its appeal but also helps improve the brand image and meet the market's demand for high-quality packaging.

[0028] Example 1: Please see Figures 1-3This embodiment provides a multi-faceted protective inner tray for packaging boxes, including a one-piece molded sheet-like body 10. The body 10 is preferably made of environmentally friendly materials, such as cardboard, and has good cushioning performance and strength. Multiple fold lines are arranged on the body 10, which can be formed by creasing or other molding processes, dividing the body 10 into multiple bendable portions. The bendable portions include a first panel 101, a second panel 102, and a third panel 103.

[0029] Please see Figure 1 The first panel 101 is configured to support the bottom of the item, forming a first protective surface. The first panel 101 is configured in a rectangular or circular shape to ensure stable support. In this embodiment, the first panel 101 is rectangular, and its size is slightly larger than the bottom of the item to provide sufficient support area.

[0030] The second panel 102 is disposed at one end of the first panel 101 in the longitudinal direction. In this embodiment, the second panel 102 is disposed above the first panel 101, and a first fold line 104 is disposed between the second panel 102 and the first panel 101. The second panel 102 can be bent along the first fold line 104 to form a second protective surface for protecting an object. The second protective surface is mainly used to cover the side of the object. In this embodiment, it is mainly used to provide protection for the back of the object. The first fold line 104 can be a continuous or intermittent indentation to ensure a smooth and precise bending process.

[0031] The third panel 103 is disposed at both ends of the second panel 102 in the lateral direction, and a second fold line 105 is disposed between the third panel 103 and the second panel 102. The third panel 103 can be bent along the second fold line 105 to form a third protective surface for protecting the item. The third protective surface is mainly used to cover the left and right sides of the item, providing horizontal protection. The design of the second fold line 105 allows the third panel 103 to bend inward, defining a storage space 106 together with the first and second protective surfaces. The shape of the storage space 106 is adapted to the shape of the item, ensuring that the item is tightly wrapped and avoiding shaking or collision during transportation.

[0032] To enhance the stability of the inner support, the first panel 101 has first support plates 107 at both ends in the lateral direction. A third fold line 108 is provided between the first panel 101 and the first support plates 107. The first support plates 107 can be bent along the third fold line 108 to form a support portion supporting the first panel 101. When the first support plate 107 is bent, it is perpendicular to the first panel 101, providing additional support and preventing the first panel 101 from sinking due to the weight of the items.

[0033] Furthermore, a fixing plate 109 is disposed at the end of the first panel 101 that is away from the second panel 102 in the longitudinal direction. In this embodiment, the fixing plate 109 is located at the lower end of the first panel 101. The fixing plate 109 is provided with an insertion hole 110 for fixing the first support plate 107. When the first support plate 107 is bent, its free end can be inserted into the insertion hole 110, and fixation is achieved through friction or engagement, ensuring that the first panel 101 can stably support the object. The fixing plate 109 can also be further bent to form a certain angle with the first panel 101 to enhance the rigidity of the overall structure. In this embodiment, the fixing plate 109 is bent twice to form a support platform below the first panel 101 to support the first panel 101.

[0034] Please refer to 1- Figure 2 To facilitate the bending of the third panel 103 along the second fold line 105, a gap 111 is provided between the first panel 101 and the third panel 103, which avoids interference between the third panel 103 and the first panel 101 when bending, making the assembly process smoother.

[0035] This embodiment further optimizes the support structure based on the above to enhance the stability of the third protective surface. Each of the two third panels 103 has a second support plate 112 disposed at the end furthest from the second panel 102 in the lateral direction. A fourth fold line 113 is disposed between the second support plate 112 and the third panel 103, and the second support plate 112 can be bent along the fourth fold line 113 to support the third protective surface formed by the third panels 103.

[0036] Specifically, the second support plate 112 is bent perpendicular to the third panel 103, providing additional cushioning and support. The fourth fold line 113 is a straight indentation, ensuring that the angle between the second support plate 112 and the third panel 103 is stable after bending.

[0037] Meanwhile, a third support plate 114 is disposed at the end of the third panel 103 away from the first panel 101 in the longitudinal direction. A fifth fold line 115 is disposed between the third support plate 114 and the third panel 103. The third support plate 114 can be bent along the fifth fold line 115 to support the third protective surface formed by the third panel 103. After being bent, the third support plate 114 can cooperate with the second support plate 112 to form a cross support network, further reducing the deformation of the third panel 103 under stress.

[0038] To fix the position of the second support plate 112, the free end of the third support plate 114 is bent in a direction parallel to the third protective surface, forming a clamping space with the third protective surface formed by the bending of the third panel 103. The size of the clamping space is adapted to the width of the second support plate 112. When the second support plate 112 is bent, its free end can be clamped in the clamping space to prevent the second support plate 112 from shifting or loosening during transportation.

[0039] In this embodiment, the end of the storage space 106 opposite to the second panel 102 is configured as an open state. This open design makes it easier for users to directly observe or take out items, while also enhancing the product display effect and improving the consumer's visual experience.

[0040] Please refer to Figures 1-3 During assembly, firstly, the fixing plate 109 is bent along the fold line between the fixing plate 109 and the first panel 10, and the end is further bent to form a support platform below the first panel 101. Next, the first support plate 107 is bent along the third fold line 108, making it perpendicular to the first panel 101. Then, the free end of the first support plate 107 is inserted into the insertion hole 110 of the fixing plate 109 for fixation. Next, the second panel 102 is bent along the first fold line 104, forming a certain angle (e.g., 90°) with the first panel 101. Finally, the third panel 103 is bent along the second fold line 105, making it perpendicular to the second panel 102 and close to the side of the object. After completing the above steps, the second support plate 112 is first bent along the fourth fold line 113, making it perpendicular to the third panel 103. Then, the third support plate 114 is bent along the fifth fold line 115, making it parallel to or at a certain angle to the third panel 103. Finally, the free end of the third support plate 114 is bent along the protective line parallel to the third protective surface to form a clamping space, and the free end of the second support plate 112 is inserted into it for fixation. This design not only improves the rigidity of the third protective surface but also simplifies the assembly process through its modular structure. Ultimately, the first, second, and third protective surfaces together form a semi-enclosed storage space 106, in which items are securely fixed.

[0041] The inner tray in this embodiment features a multi-faceted protective design, effectively resisting impacts from different directions, making it particularly suitable for packaging fragile or high-value items. Meanwhile, the introduction of a support structure and fixing plate enhances overall stability, the gap design simplifies the assembly process, and the open design optimizes the display effect.

[0042] This embodiment provides a multi-faceted protective inner tray that can be applied to packaging boxes. The outer wall of the inner tray is adapted to the shape of the packaging box's receiving cavity. When the inner tray is placed inside the receiving cavity, the outer wall of the inner tray fits tightly against the inner wall of the receiving cavity or leaves a small gap to prevent the inner tray from shaking inside the box.

[0043] The storage space 106 of the multi-faceted protective inner tray perfectly matches the shape of the item to be packaged. For example, when the item is a smartphone, the size of the storage space 106 is slightly larger than the size of the phone, ensuring that the phone is tightly wrapped. The lid of the packaging box can be designed to be transparent or have a window, corresponding to the opening state 112 of the inner tray, so that the item can be observed even before it is fully removed.

[0044] During transportation, additional filling materials or reinforced corner tags can be added to the outside of the packaging box, but the multi-faceted protection design of the inner tray can effectively reduce the reliance on external cushioning. Its lightweight design and efficient protective performance can reduce packaging costs while improving the user experience.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
