Description

Technical Field

[0001] This utility model relates to the field of packaging containers, specifically to a square box with a secondary receiving chamber. Background Technology

[0002] Existing square boxes typically consist of a box body and a hinged lid. The box body, enclosed by a back panel and side panels, forms the main compartment for holding items. These boxes are widely used in packaging, gifts, and electronic product storage. However, the existing box structure has some limitations. For example, the main compartment is usually a single space, lacking an effective partitioning mechanism. When multiple items of different shapes or sizes need to be placed simultaneously, they are prone to mixing and colliding, leading to damage or disarray. Especially for fragile or delicate items, such as cosmetics and electronic accessories, existing boxes cannot provide stable locking mechanisms, and items may wobble during transportation or movement, affecting safety.

[0003] To address the issue of internal partitioning, some existing technologies attempt to incorporate fixed partitions within the enclosure. For example, partitions are installed by gluing or inserting to divide the main chamber into multiple areas. However, these partitions often have a fixed structure, making it impossible to flexibly adjust the partition area according to the size of the objects, resulting in poor applicability. Furthermore, fixed partitions may increase manufacturing complexity and make it difficult to achieve reliable positioning; objects may still shift out of the gaps between the partitions. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a square box with a secondary receiving chamber:

[0005] A square box with a secondary receiving chamber includes a box body and a flip-top that covers the box body. The box body includes a back panel, a front inner panel, a front outer panel, a first side panel, and a second side panel. The back panel, the front outer panel, the first side panel, and the second side panel enclose a main receiving chamber. The two ends of the first side panel are integrally connected to a first extension portion. The first extension portion includes an integrally vertically arranged folding plate and a snap-fit ​​plate. The two folding plates are respectively bonded to the back panel and the front outer panel. The snap-fit ​​plates of the two extension portions are mutually snap-fitted and adapted. The side panel, the folding plate, and the snap-fit ​​plate enclose a secondary receiving chamber.

[0006] Preferably, the snap-fit ​​plate includes a snap-fit ​​plate body and an outer extension strip. The root of the outer extension strip is integrally connected to the snap-fit ​​plate body, and a snap-fit ​​gap is provided between the end of the outer extension strip and the snap-fit ​​plate body. The outer extension strips of the two snap-fit ​​plates are respectively connected to the upper and lower parts of the snap-fit ​​plate body, and the two snap-fit ​​gaps are interlocked to form a snap-fit ​​fit. This utility model achieves a dual connection between the side plate and the back plate and the front outer plate through both adhesive bonding and snap-fit. The interlocking snap-fit ​​fit structure between the two snap-fit ​​plates forms a robust mechanical interlock.

[0007] Preferably, the second side plate is integrally connected to the front inner plate at the side end corresponding to the front outer plate. The outer end of the front inner plate is provided with an outwardly extending locking part. The locking part is provided with a locking groove that is adapted to the locking plate body. The locking groove is located at the bottom of the locking part and extends longitudinally. The other side end of the second side plate is provided with a second extension part, which is bonded to the inner surface of the back plate.

[0008] Preferably, the upper part of the front inner panel is provided with a notch, the front outer panel is provided with an insertion gap, and the front end of the flip cover is provided with an outwardly protruding insertion plate. The insertion plate passes through the insertion gap and the notch in sequence and abuts against the inner side of the front inner panel.

[0009] Preferably, the folding plate is composed of one or more square plates, with creases between them. The square plates can be directly folded and adapted to each other, and are also adapted to each other by adhesive or magnetic attraction. Adjacent square plates in the folded state have locking gaps for the insertion of the locking part. The user can control the area of ​​the secondary receiving chamber by controlling the number of folded square plates. The locking part is a transverse strip structure, and multiple locking slots are evenly distributed at the bottom of the locking part. This invention, by designing the folding plate constituting the secondary receiving chamber as being composed of multiple square plates with creases, allows the user to quickly and conveniently adjust the actual size and volume of the secondary receiving chamber by folding different numbers of square plates. This design enables a box to adapt to different sizes and quantities of objects, achieving a leap from "fixed separation" to "intelligent adjustment," greatly improving the product's versatility and space utilization, and solving the pain point of traditional packaging boxes being inflexible due to fixed separation.

[0010] Preferably, a transverse magnetic metal strip is adhered to the outer surface of the back plate, and a longitudinal inner magnetic strip is adhered to the surface of the square plate. When the square plate is attached to the inner surface of the back plate, the inner magnetic strip and the magnetic metal strip magnetically attract each other. The inner magnetic strips of adjacent square plates are staggered to avoid mutual collision when adjacent square plates are folded and closed. By the magnetic attraction between the magnetic metal strip on the outer surface of the back plate and the inner magnetic strip of the square plate that can be attached to it after folding, a non-fixed stable holding force is provided for the foldable plate. When the user adjusts the size of the secondary chamber, it is only necessary to simply fold it and make it magnetically attracted to the back plate to complete the fixation, which is extremely convenient. More importantly, the staggered design of the inner magnetic strips of adjacent square plates perfectly avoids the problem of magnets repelling or colliding when folding and closing, ensuring the reliability of the structure.

[0011] Beneficial effects: This box has an additional secondary compartment inside the main compartment. The secondary compartment has two functions: first, it can divide the main compartment into different areas to accommodate different items; second, the latching plate of the secondary compartment can restrain and limit the items placed in the main compartment, thus securing the items and preventing them from shaking.

[0020] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described with reference to Examples 1-2.

[0021] Example 1: As Figure 1-3As shown, a square box with a secondary receiving chamber includes a box body and a flip-top that closes the box body. The box body includes a back panel, a front inner panel, a front outer panel, a first side panel, and a second side panel. The back panel, front outer panel, first side panel, and second side panel enclose the main receiving chamber. The two ends of the first side panel are integrally connected to a first extension portion. The first extension portion includes an integrally formed vertically arranged folding plate and a snap-fit ​​plate. The two folding plates are respectively bonded to the back panel and the front outer panel. The folding plate is composed of a square plate. The snap-fit ​​plates of the two extension portions interlock and adapt to each other. The side panel, folding plate, and snap-fit ​​plate enclose the secondary receiving chamber. The snap-fit ​​plate includes a snap-fit ​​body and an extension strip. The root of the extension strip is integrally connected to the snap-fit ​​body. A locking gap is provided between the end of the extension strip and the snap-fit ​​body. The extension strips of the two snap-fit ​​plates are respectively connected to the upper and lower parts of the snap-fit ​​body. The two locking gaps interlock and interlock to form a locking adaptation.

[0022] The second side panel is integrally connected to the front inner panel at the side end corresponding to the front outer panel. The outer end of the front inner panel has an outwardly extending locking portion. The locking portion has a locking groove that matches the locking plate body. The locking groove is located at the bottom of the locking portion and extends longitudinally. The other side end of the second side panel has a second extension portion, which is bonded to the inner surface of the back panel. The upper part of the front inner panel has a notch, and the front outer panel has an insertion gap. The front end of the flip cover has an outwardly protruding insertion plate portion. The insertion plate portion passes through the insertion gap and the notch in sequence and abuts against the inner side of the front inner panel.

[0023] The secondary containment chamber of this invention is not merely a simple partition; its snap-fit ​​plate simultaneously separates the main chamber area and provides lateral support and positioning for items placed within the main chamber. This design effectively prevents items within the main chamber from shaking or colliding during transportation or movement, making it particularly suitable for fragile items, precision instrument parts, and other scenarios requiring stable packaging, significantly improving the safety and reliability of the packaging.

[0024] Example 2: As Figure 4-7As shown, a square box with a secondary receiving chamber includes a box body and a flip-top that closes the box body. The box body includes a back panel, a front inner panel, a front outer panel, a first side panel, and a second side panel. The back panel, front outer panel, first side panel, and second side panel enclose the main receiving chamber. The two ends of the first side panel are integrally connected to a first extension portion. The first extension portion includes an integrally formed vertically arranged folding plate and a snap-fit ​​plate. The two folding plates are respectively bonded to the back panel and the front outer panel. The snap-fit ​​plates of the two extension portions interlock and adapt to each other. The side panel, folding plate, and snap-fit ​​plate enclose the secondary receiving chamber. The snap-fit ​​plate includes a snap-fit ​​body and an extension strip. The root of the extension strip is integrally connected to the snap-fit ​​body. A locking gap is provided between the end of the extension strip and the snap-fit ​​body. The extension strips of the two snap-fit ​​plates are respectively connected to the upper and lower parts of the snap-fit ​​body. The two locking gaps interlock and interlock to form a locking adaptation.

[0025] The upper part of the front inner panel is provided with a notch, the front outer panel is provided with an insertion gap, and the front end of the flip cover is provided with an outwardly protruding insertion plate. The insertion plate passes through the insertion gap and the notch in sequence and abuts against the inner side of the front inner panel.

[0026] The second side plate is integrally connected to the front inner plate at the side end corresponding to the front outer plate. The outer end of the front inner plate has an outwardly extending locking part. The locking part has a locking groove that matches the locking plate body. The locking groove is located at the bottom of the locking part and extends longitudinally. The other side end of the second side plate has a second extension, which is bonded to the inner surface of the back plate. The folding plate is composed of multiple square plates with fold lines between them. Each square plate can be folded and adapted to each other. The folded square plates are magnetically adapted to each other. Adjacent square plates in the folded state have locking gaps for the locking part to be inserted. The user can control the area of ​​the secondary receiving chamber by controlling the number of folded square plates. The locking part is a transverse strip structure. Multiple locking grooves are evenly distributed at the bottom of the locking part. The outer surface of the back panel is bonded with a transverse magnetic metal strip, and the surface of the square plate is bonded with a longitudinal inner magnetic strip. When the square plate is attached to the inner surface of the back panel, the inner magnetic strip and the magnetic metal strip are magnetically attracted to each other. The inner magnetic strips of adjacent square plates are staggered to avoid the inner magnetic strips of adjacent square plates hitting each other and conflicting when they are folded and closed.

[0027] Operating principle: such as Figure 4 As shown, in its folded state, the square plate, through the mutual magnetic attraction between the magnetic metal strip and the inner magnetic strip, causes the volume of the secondary receiving chamber to be reduced. For example... Figure 5-7 As shown, by unfolding each square plate, the buckle plate and the locking groove on the side of the locking part near the front inner plate are mutually engaged and adapted, thereby increasing the volume of the secondary receiving chamber.

[0028] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
