AI Technical Summary
The lids of existing cardboard boxes are prone to separating from the box body during reuse, causing products to fall out, and there is a lack of effective fixing mechanisms.
A lid-fixing cardboard box was designed. By setting a limiting block and a limiting band on the box body, the limiting band can slide into the groove and be fixed with the hook. Combined with the design of elastic elements and sponge blocks, the lid can be stably fixed.
This design ensures the carton lid is securely fixed, preventing the lid from separating from the carton and the product from falling out during reuse, thus improving the convenience and safety of using the carton.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box technology, and more specifically, to a cardboard box with a fixed lid. Background Technology
[0002] Cardboard boxes are a type of packaging material, primarily used for product packaging, and they also provide protection for the product.
[0003] Some existing cardboard boxes have a top and bottom lid design, and some people reuse these boxes. However, the lids of these boxes are usually not fixed to the boxes themselves. This can easily lead to the boxes and lids separating and products falling out when the boxes are overturned during reuse.
[0004] Therefore, a new solution is needed to supplement the existing cardboard box category. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lid-fixed cardboard box.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a lid-fixed cardboard box, including a box body and a lid, wherein a plurality of limiting blocks are fixedly arranged on the box body, and the limiting blocks are provided with grooves; a plurality of limiting bands one are bonded to the inner wall of the lid, and limiting bands two are slidably arranged between the limiting bands one and the lid; the limiting bands two can be embedded in the groove area; the limiting blocks are provided with elastic members; the limiting bands two penetrate the lid; and the limiting bands two and the lid are provided with fixings that can fix each other.
[0007] The present invention is further configured such that: the fixing member is configured as a hook, and the limiting band and the hook on the cover can be interlocked and mutually fixed.
[0008] The present invention is further configured such that the elastic element is a sponge block, and the sponge block can abut and push the limiting band two.
[0009] The present invention is further configured such that the limiting block is provided with rounded corners.
[0010] The present invention is further configured such that the second limiting band is a transparent TPU band.
[0011] The present invention is further configured such that one of the limiting bands is a plastic sheet.
[0012] In summary, this utility model has the following beneficial effects: after the user puts the lid on the box, the lid is locked on the box by pulling the limiting band two and fixing the hooks together, which makes it convenient for the user to transport or store the carton when it is reused.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] A type of cardboard box with a fixed lid, such as Figures 1-3 As shown, the device includes a box body 1 and a lid 2. Multiple limiting blocks 3 are fixedly installed on the box body 1, and grooves 4 are formed on the limiting blocks 3. Several limiting bands 5 are adhesively connected to the inner wall of the lid 2, and limiting bands 6 are slidably positioned between the limiting bands 5 and the lid 2. The limiting bands 6 can be embedded into the grooves 4. After the user places the lid 2 on the box body 1, they can pull the limiting bands 6 to embed them into the grooves 4 of the limiting blocks 3. During this process, the stretching of the limiting bands 6 forms a fixation, thus securing the lid 2 to the box body 1. Elastic elements 7 are provided on the limiting blocks 3. The limiting bands 6 penetrate the lid 2, and fixing elements are provided on the limiting bands 6 and the lid 2 to fix each other. The hook 8 and the limit band 6 and the hook 8 on the cover 2 can be interlocked and fixed together. When the limit band 6 is relaxed, the area where it is embedded in the groove 4 will be pushed out by the elastic member 7 so that the cover 2 can be easily removed from the box 1. The hook 8 is designed to make the limit band 6 exert pressure on the elastic member 7 when it is stretched. At the same time, after the limit band 6 is embedded in the groove 4, the long side of the limit band 6 abuts against the inner wall of the groove 4, thus fixing its position. The elastic member 7 is a sponge block. The sponge block can abut and push the limit band 6. The sponge block has an elastic deformation effect and can still push the limit band 6 out after multiple presses.
[0019] The limit block 3 is provided with rounded edges. The rounded edges are provided to reduce the wear between the limit band 6 and the limit block 3 and extend the service life of the limit band 6.
[0020] Limiting strip 5 is made of plastic sheet, and limiting strip 6 is made of TPU transparent strip. The plastic sheet and TPU elastic strip are designed to reduce the friction of limiting strip 6 during the sliding process, making it easier for the user to slide.
[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
