Abstract
Description
Technical Field
[0001] This application relates to the field of turnover box technology, and in particular to an inner liner bag for turnover boxes and a turnover box. Background Technology
[0002] In modern warehousing and logistics, especially in the supply chain of high-value products such as automotive parts and precision instruments, a type of turnover box with a metal frame is commonly used to achieve heavy-duty stacking and reuse. These turnover boxes typically include top and bottom frames and several metal uprights connecting them, forming a high-strength load-bearing structure. To protect the items inside from scratches, bumps, and contamination during transportation, and to facilitate keeping the turnover box itself clean, it is usually necessary to place inner lining bags inside.
[0003] A common practice is to use large general-purpose plastic bags or ton bags as linings. However, such general-purpose bags cannot be well matched with the structure of the aforementioned metal frame turnover boxes. After being placed inside, they are prone to producing a lot of wrinkles or piling up at the bottom and corners of the box. This not only wastes effective storage space but may also cause damage due to uneven stress, failing to meet the requirements of high-intensity and high-frequency cyclic use in industrial environments. Utility Model Content
[0004] In order to be compatible with metal frame turnover boxes with uprights, this application provides an inner liner bag for turnover boxes and a turnover box.
[0005] In a first aspect, this application provides an inner lining bag for turnover boxes, which adopts the following technical solution: A liner bag for a turnover box includes a bag body having a bag opening and a closed bag bottom; A connector, located at the edge of the bag opening and / or the edge of the bag bottom, is used to connect the bag body to the turnover box; A limiting component is provided on the side wall of the bag body and is used to fit around the outside of the upright of the turnover box.
[0006] By adopting the above technical solution, the structure of the limiting component allows the inner liner bag to bypass the internal uprights of the turnover box, enabling the bag to fit smoothly against the inner wall of the box, avoiding wrinkles and space waste caused by the uprights obstructing the view. The connecting component firmly fixes the edge of the inner liner bag to the turnover box, preventing the bag from sliding or sinking during transportation and use. The combination of these two components ensures that the inner liner bag and the turnover box form a stable and fitted whole, improving the reliability of protection and space utilization, and better meeting the requirements of high-intensity, high-frequency cyclic use.
[0007] Optionally, multiple connectors are provided, and the multiple connectors are arranged at intervals along the edge of the bag opening and / or the edge of the bag bottom.
[0008] By adopting the above technical solution, the fixing force can be distributed more evenly on the edge of the bag, avoiding local stress concentration and bag sagging that may be caused by single-point fixing, thus making the installation state of the inner liner bag more flat and stable.
[0009] Optionally, the connector is a connecting strap with Velcro, wherein the Velcro with a rough surface and the Velcro with a barbed surface are located on the same side of the connecting strap.
[0010] By adopting the above technical solution, the operation is simple and quick, and fixing and disassembly can be completed without additional tools, facilitating the replacement and cleaning of the inner lining bag. At the same time, by setting the rough side and the barbed side on the same side, a self-adhesive structure is formed, which allows the connecting strap to be wrapped around the frame of the turnover box for overlapping and fixing, enhancing the flexibility and applicability of the connection.
[0011] Optionally, the cross-section of the bag is rectangular.
[0012] By adopting the above technical solution, the bag body is designed with a rectangular cross-section, which can accurately match the internal contour of the mainstream rectangular turnover boxes on the market, reducing the corner wrinkles caused by shape mismatch, allowing the inner lining bag to better fill the box space and improve the neatness of loading.
[0013] Optionally, the limiting member includes at least one bag body sleeve, which is arranged along the length direction of the bag body and is located in the planar area of the side wall of the bag body.
[0014] By adopting the above technical solution, the main body of the bag can be completely and smoothly attached to the box wall, ensuring precise fit with the uprights located on the side wall and avoiding bulging of the bag in the middle of the side wall.
[0015] Optionally, the limiting member further includes at least one corner sleeve, which is arranged along the length direction of the bag body and is located in the corner area of the side wall of the bag body.
[0016] By adopting the above technical solution, the added corner sleeve is used to fit the uprights at the corners of the turnover box, which can further enhance the positioning effect of the inner lining bag. At the same time, the corner sleeve also reinforces the weak corner of the bag body, improving the overall structural strength and durability of the inner lining bag.
[0017] Optionally, the bag body is provided with a cap at the bag opening, and a zipper is provided between the cap and the bag body.
[0018] By adopting the above technical solution, the designed cap and zipper can easily seal the bag opening, effectively preventing external pollutants such as dust and moisture from entering the bag, providing more comprehensive protection for the contents. The zipper design enables quick access and convenient operation, improving work efficiency.
[0019] Optionally, the bag body has a double-layer structure.
[0020] By adopting the above technical solution and using a double-layer structure, the thickness and strength of the bag are improved, resulting in better puncture and tear resistance and a certain cushioning capacity. This provides more reliable protection for heavier items or items with sharp edges and corners, and extends the service life of the inner lining bag.
[0021] Optionally, a protective film layer is provided on the inner wall of the bag.
[0022] By adopting the above technical solution, a functional protective film layer can be coated on the inner wall, which can give the inner lining bag specific protective properties, such as using a soft velvet film layer to prevent scratches on the glossy surface, or using an antistatic film layer to protect electronic components.
[0023] Secondly, this application provides a turnover box, which adopts the following technical solution: A turnover box includes an inner liner bag for turnover boxes as described above, and a box body. The inner liner bag for turnover boxes is housed in the box body. The box body includes two side frames and a column disposed between the two side frames. The connector is detachably connected to the side frames, and the limiting member is sleeved on the outside of the column.
[0024] By adopting the above technical solution, the turnover box combines a box body with high load-bearing capacity with an inner liner bag with protective and adaptable capabilities to form a complete, ready-to-use logistics unit, ensuring the reliability of the packaging.
[0025] In summary, this application includes the following beneficial technical effects: 1. By setting limiting parts and connecting parts that cooperate with the uprights and frame of the turnover box, the inner lining bag is accurately matched and reliably fixed to the box body, which solves the problems of easy displacement and non-fitting of traditional inner lining bags, and improves the protective effect and space utilization.
[0026] 2. By integrating the compatible inner lining bag with the turnover box body, a complete and standardized solution for the recycling of heavy-duty goods is provided, which simplifies the packaging process and ensures product safety throughout the logistics process.

[0029] The following combination Figures 1-5 This application will be described in further detail.
[0030] This application discloses an inner lining bag for turnover boxes. (Refer to...) Figure 1 and Figure 2 The inner liner bag for the turnover box includes a bag body 1 made of flexible material. The bag body 1 has a bag opening 11 for loading items and a closed bag bottom 12, which together form a storage space. To match the common shape of turnover boxes, the cross-section of the bag body 1 is designed to be rectangular, that is, the bag body 1 is in the shape of a cuboid or cube in its normal state. Because the inner liner bag is made of flexible material, it is easy to fold, store, and transport.
[0031] Reference Figure 2 and Figure 3 The bag body 1 has connectors 2 at both the edge of the opening 11 and the edge of the bottom 12. The connectors 2 are used to connect and fix the bag body 1 to the upper and lower frames 61 of the turnover box. With this fixing method, the inner lining bag can always stay in the correct position when loading and unloading goods or experiencing transportation bumps, thus continuously providing stable protection for the contents.
[0032] Furthermore, to achieve a more stable fixation, multiple connectors 2 are provided, evenly spaced along the periphery of the bag opening 11 and the periphery of the bag bottom 12. This multi-point fixing method makes the tensile force distribution more uniform, avoiding excessive force at a single point that could cause local deformation of the bag body 1. In this embodiment, the connector 2 is a connecting strap 21 sewn with Velcro 22. Each connecting strap 21 has two Velcro pieces 22 sewn on it, located on the same side of the connecting strap 21. One Velcro piece 22 has a rough surface, and the other Velcro piece 22 has a barbed surface. The rough and barbed surfaces can cooperate and adhere to each other for fixation. In use, the connecting strap 21 is wrapped around the edge 61 of the turnover box, and then its rough and barbed surfaces are adhered to each other to complete the quick fixation. This structure is simple to operate, can be reused, and is easy to adjust the tightness, improving the convenience of operation.
[0033] In other embodiments, the connector 2 may also be a snap-on connector, including a webbing fixed to the bag body 1 and a set of mating male and female snaps, which are fastened together to achieve a secure lock. Alternatively, the connector 2 may be a hook-type connector, including a hook connected to the bag body 1 via an elastic cord, which can be quickly hooked onto the frame 61 of the box body 6. Yet another example is that the connector 2 may also be a simple tie-on structure, where the cord fixed to the bag body 1 is knotted for secure fastening.
[0034] Reference Figure 3 and Figure 4 Limiting components 3 are also provided on the side wall of the bag body 1. During installation, the uprights 62 of the turnover box can pass directly through these limiting components 3, so that the side wall of the bag body 1 can bypass the uprights 62 and fit smoothly against the inner wall of the turnover box, avoiding the bag body 1 being lifted by the uprights 62 to form a cavity or wrinkles, thus making effective use of the internal space.
[0035] The limiting component 3 includes a bag body sleeve 31 and corner sleeves 32 arranged along the length of the bag body 1. Four bag body sleeves 31 are provided, corresponding to the four side walls of the bag body 1. The bag body sleeves 31 are sewn into the central planar area of the outer side wall of the bag body 1, with their upper and lower edges remaining open to allow insertion of the upright 62 located in the middle of the side wall of the turnover box. Four corner sleeves 32 are also provided, corresponding to the four corners of the bag body 1. The corner sleeves 32 are sewn into the corners of the inner side wall of the bag body 1. Their upper and lower edges remain open to allow insertion of the upright 62 at the corner of the turnover box. The combined use of these two types of sleeves ensures that every surface and corner of the inner lining bag fits tightly against the turnover box. Simultaneously, the sewn structure of the corner sleeves 32 reinforces the corner areas of the bag body 1, improving overall durability.
[0036] In other embodiments, the limiting member 3 may also be a limiting collar, which can be sewn and fixed to the outer or inner side wall of the bag body 1, so that the limiting collar is fitted onto the column 62 on the turnover box to limit the inner lining bag.
[0037] Reference Figure 3 To enhance the overall performance of the inner lining bag, the bag body 1 adopts a double-layer structure made of double-layer fabric stitched together. This structure has better tear resistance and cushioning performance than a single-layer structure. Meanwhile, to facilitate the storage and retrieval of items and provide dust protection, a top cover 13 is sewn onto the bag opening 11 of the bag body 1. A rectangular access opening 131 is opened in the center of the top cover 13. A rectangular sealing cap 4 is sewn onto one side wall of the access opening 131. One end of the sealing cap 4 is sewn to the top cover 13, and a zipper 5 is provided between the other three sides of the sealing cap 4 and the top cover 13. The zipper 5 is a two-way zipper, so the user can easily put in and take out items simply by operating the zipper 5.
[0038] To ensure the inner liner bag maintains its shape even when empty, preventing sagging and wrinkling, one or two layers can be made of materials with a certain degree of rigidity and support. For example, the outer layer can use conventional flexible Oxford cloth or canvas to ensure abrasion resistance and flexibility, while the inner layer can use a rigid or semi-rigid material, such as non-woven fabric reinforced with rigid fibers. This structure, with a rigid inner layer and a flexible outer layer, allows the inner liner bag to naturally take shape under the support of the inner layers, resulting in straight and crisp bag walls. After installation, it presents a neat rectangular shape without much tidying, greatly improving loading efficiency and visual appeal.
[0039] In addition, to provide special protection for the items packed in the turnover box, a soft protective film layer is also applied to the inner wall of the bag body 1 to prevent scratches, improve the wear resistance of the inner lining bag, and facilitate quick cleaning of the inner lining bag.
[0040] The implementation principle of the inner lining bag for a turnover box according to this application embodiment is as follows: In use, first unfold the inner lining bag and place it inside the turnover box body 6. Pass the upright post 62 in the middle of the side of the turnover box through the bag body sleeve 31 on the inner lining bag, and pass the upright posts 62 at the corners of the turnover box through the corner sleeves 32 on the inner lining bag. Then, wrap the connecting strap 21 at the edge of the bag opening 11 around the top frame 61 of the turnover box and secure it with Velcro 22. Similarly, wrap the connecting strap 21 at the edge of the bag bottom 12 around the bottom frame 61 of the turnover box and secure it with Velcro 22. After the inner lining bag is installed, it is firmly and smoothly attached to the inside of the turnover box. Items can be loaded and unloaded by unzipping the zipper 5 on the cover 4.
[0041] Reference Figure 3 and Figure 5This embodiment also discloses a turnover box, which includes a box body 6. The box body 6 includes two upper and lower side frames 61 and multiple uprights 62 disposed between the two side frames 61. The side frames 61 are rectangular, and the side frames 61 and the uprights 62 are detachably connected. In use, first remove the top side frame 61, then put the bag body sleeve 31 on the uprights 62 on the side of the box body 6, put the corner sleeve 32 on the uprights 62 at the corners of the box body 6, and then fix the top side frame 61 to the top of the uprights 62. Next, wrap the connecting strap 21 of the bag opening 11 around the top side frame 61 of the turnover box and tighten it with Velcro 22, and wrap the connecting strap 21 of the bottom side 12 around the bottom side frame 61 of the turnover box and tighten it with Velcro 22 to complete the installation of the inner lining bag.
[0042] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
