Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0043] Figure 1 The following is a schematic diagram of the structure of a cardboard box 100 provided for some embodiments of this application, wherein the cardboard box 100 is in an unfolded state; Figure 2 A front view of a carton 100 provided for some embodiments of this application, wherein the carton 100 is in an unfolded state; Figure 3 A schematic diagram of the structure of a carton 100 in a first folded state provided for some embodiments of this application; Figure 4 This is a structural schematic diagram of a carton 100 in a second folded state, provided for some embodiments of this application.
[0044] Reference Figures 1 to 4 An embodiment of this application provides a carton 100, which has an unfolded state and is configured to be selectively folded to a first folded state or a second folded state in the unfolded state. The carton 100 is cuboid in both the first folded state and the second folded state.
[0045] The length of the carton 100 in the second folded state is greater than the length in the first folded state, and the width in the second folded state is greater than the width in the first folded state.
[0046] In this embodiment, the cardboard box 100 is easy to stack and transport when unfolded. When in use, it can be folded to a first folded state to package smaller products, or folded to a second folded state to package larger products. In this way, the cardboard box 100 is compatible with products of different sizes, which helps improve its compatibility and enhances its flexibility for secondary recycling.
[0047] In some embodiments, carton 100 is corrugated cardboard.
[0048] Figure 5 A schematic diagram of the folding process of the carton 100 provided for some embodiments of this application; Figure 6 This is a schematic diagram illustrating different folding processes of the folding plate 30 of this application, with reference to... Figures 1 to 6 In some embodiments, the carton 100 includes a pair of first side panels 10 and a pair of second side panels 20. In a first folded state or a second folded state, the pair of first side panels 10 are positioned opposite each other and spaced apart along a first direction X. In the first folded state or the second folded state, the pair of second side panels 20 are positioned opposite each other and spaced apart along a second direction Y. Adjacent first side panels 10 and second side panels 20 are connected by a folding plate 30, and the first direction X is perpendicular to the second direction Y.
[0049] In the first folded state, a pair of first enclosure panels 10 and a pair of second enclosure panels 20 enclose and form the four side walls of the carton 100; in the second folded state, part of the folding panel 30 is coplanar with the first enclosure panel 10, and part of the folding panel 30 is coplanar with the second enclosure panel 20. The folding panel 30, the pair of first enclosure panels 10 and the pair of second enclosure panels 20 enclose and form the four side walls of the carton 100.
[0050] For example, the first side panel 10 forms the narrow face of a cuboid, and the second side panel 20 forms the large face of the cuboid, with the area of the second side panel 20 being larger than the area of the first side panel 10. In the first folded state, the narrow face of the four side walls of the carton 100 is formed by the first side panel 10, and the large face is formed by the second side panel 20. The total area of the four side walls is the sum of the areas of the two first side panels 10 and the two second side panels 20. In the second folded state, the first side panel 10 and part of the folding panel 30 together form the narrow face, and the second side panel 20 and part of the folding panel 30 together form the large face. In this case, the total area of the four side walls is the sum of the areas of the two first side panels 10, the two second side panels 20, and the four folding panels 30.
[0051] For example, the first direction X is the length direction of the carton 100, and the second direction Y is the width direction of the carton 100.
[0052] For example, four folding panels 30 are provided, and the four folding panels 30 are respectively provided at the four corners of the carton 100. One end of each folding panel 30 is connected to the first side panel 10, and the other end is connected to the second side panel 20.
[0053] It is understood that the folding plate 30 can fold the carton 100 to a first folded state, or unfold it to widen the length and width of the carton 100, thereby putting the carton 100 into a second folded state.
[0054] Reference Figure 6 In some embodiments, the folding panel 30 includes a first panel 31 and a second panel 32. In either the first folded state or the second folded state, the first panel 31 is connected to the second panel 32, with the first panel 31 connected to the first surrounding panel 10 and the second panel 32 connected to the second surrounding panel 20. In the first folded state, the folding panel 30 is folded into the interior of the carton 100. In the second folded state, the folding panel 30 is unfolded, such that the first panel 31 is coplanar with the first surrounding panel 10, and the second panel 32 is coplanar with the second surrounding panel 20.
[0055] Figure 6 Process A corresponds to the second folded state of carton 100, process B corresponds to the first folded state of carton 100, and process C corresponds to the intermediate process between processes A and B. In one example, in the second folded state, the folding plate 30 is folded 90°, and the first plate 31 and the second plate 32 are perpendicular to each other (e.g., ...). Figure 6 As shown in process A); in the first folded state, the folding plate 30 is folded in half, and the first plate 31 and the second plate 32 overlap (as shown in process A). Figure 6 (As shown in process B).
[0056] It should be noted that the carton 100 can be switched between processes A, B, and C to fold it to the desired state. If the carton 100 is initially in an unfolded state, the folding plate 30 folds a crease through process C and then proceeds to process B, so that the folding plate 30 is located inside the first enclosure 10, forming the first folded state of the carton 100. If the carton 100 is initially in a first folded state, the folding plate 30 can be unfolded through process C to process A, forming the second folded state of the carton 100. If the carton 100 is initially in a second folded state, the folding plate 30 can be unfolded through process C to process A, forming the first folded state of the carton 100. In addition, if the carton 100 is initially in an unfolded state, the carton 100 can also be directly folded from the unfolded state to the second folded state, without the folding plate 30 needing to go through process C or process B.
[0057] In some embodiments, in the first folded state, the first panel 31 and the second panel 32 are folded together. It is understood that the first panel 31 and the second panel 32 have the same area and can overlap after being folded. With this configuration, after the first panel 31 and the second panel 32 are folded together, the first side panel 10 and the second side panel 20 are adjacent and will not be misaligned, which helps to improve the structural stability of the carton 100.
[0058] In some embodiments, the carton 100 further includes a fixing plate 40 for keeping the first plate 31 and the second plate 32 folded together in the first folded state. By providing the fixing plate 40, the folded plate 30 can be fixed in the folded state to prevent it from unfolding, thereby improving the structural stability of the carton 100 in the first folded state.
[0059] In some embodiments, the fixing plate 40 is connected to the first enclosure plate 10. In the first folded state, the folding plate 30 is folded to the inside of the first enclosure plate 10 and located between the first enclosure plate 10 and the fixing plate 40.
[0060] For example, the fixing plate 40 is parallel to the first enclosure plate 10.
[0061] In some embodiments, to reduce the difficulty of folding the fixing plate 40, a first folding guide 42 and a second folding guide 43 may be provided at the connection between the fixing plate 40 and the first enclosure 10, with the second folding guide 43 located between the first folding guide 42 and the first enclosure 10. In the second folded state, the fixing plate 40 is folded 90° along the second folding guide 43. In this state, the fixing plate 40 can be folded horizontally to cooperate with the sealing cardboard of the carton 100 opening to cover the opening of the carton 100. In the first folded state, the fixing plate 40 is folded 90° along the first folding guide 42 and 90° along the second folding guide 43. In this state, the fixing plate 40 can be folded vertically to fix the folding plate 30.
[0062] By providing the first folding guide 42 and the second folding guide 43, the difficulty of folding the fixing plate 40 in the first folding state or the second folding state can be reduced.
[0063] The first folding guide 42 and the second folding guide 43 can be indented, crimped, cut, grooved, etc.
[0064] In some embodiments, the fixing plate 40 has a tongue 41, and a crease is formed between the second enclosure plate 20 and the second plate body 32. A tongue channel 60 is provided on the crease to cooperate with the tongue 41. In the first folded state, the tongue 41 is inserted into the tongue channel 60 to confine the folded plate 30 between the first enclosure plate 10 and the fixing plate 40. This arrangement reduces the difficulty of fixing the folded plate 30 to the fixing plate 40, while improving the structural stability of the carton 100 in the first folded state.
[0065] In an embodiment where the first enclosure 10 forms a narrow face of a cuboid and the second enclosure 20 forms a large face of a cuboid, in the second folded state, the tongue channel 60 is located on the large face of the cuboid.
[0066] Reference Figure 3 and Figure 4 In some embodiments, the carton 100 further includes a pair of sealing plates 50, each sealing plate 50 being configured to be foldable. The pair of sealing plates 50 are positioned opposite each other and spaced apart along a third direction Z. A second enclosure 20 is connected between the pair of sealing plates 50. The pair of sealing plates 50 are used to cover a first opening defined by a pair of first enclosures 10 and a pair of second enclosures 20 in a first folded state, and to cover a second opening defined by a folding plate 30, a pair of first enclosures 10 and a pair of second enclosures 20 in a second folded state. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0067] It is understood that in the first folded state, the structure formed by the first enclosure 10 and the second enclosure 20 has a first opening at the top and bottom, which is covered by the sealing plate 50; while in the second folded state, the structure formed by the first enclosure 10, the second enclosure 20 and the folding plate 30 has a second opening at the top and bottom, which is also covered by the sealing plate 50.
[0068] For example, the third party directs Z to the height direction of the carton 100 in the first folded state or the second folded state.
[0069] In this embodiment, the sealing plate 50 serves as a physical barrier, covering the first opening in the first folded state and the second opening in the second folded state, reducing the risk of internal items falling out due to vibration or tilting during transportation.
[0070] In some embodiments, each sealing plate 50 includes a sealing plate 51 and a pair of first wing plates 52. The pair of first wing plates 52 are arranged opposite to each other and spaced apart along a first direction X. The first wing plates 52 are connected to a second enclosure plate 20. The sealing plate 51 is connected between the pair of first wing plates 52. Each first wing plate 52 corresponds to a first enclosure plate 10. In a first folded state, the first wing plate 52 is folded to the inside of the first enclosure plate 10. In a second folded state, the first wing plate 52 and the sealing plate 51 are coplanar.
[0071] Specifically, in the first folded state, the first wing plate 52 is folded 90° relative to the sealing plate 51, located inside the first enclosure 10, and parallel to the first enclosure 10; in the second folded state, the first wing plate 52 and the sealing plate 51 are coplanar.
[0072] In this embodiment, in the first folded state, the first wing plate 52 can be folded to the inside of the carton 100 to strengthen the structure; while in the second folded state, it can be flattened and together with the sealing plate 51, it can seal the opening of the carton 100.
[0073] In some embodiments, in the second folded state, the fixing plate 40 is rotated 90° relative to the first enclosure plate 10, located inside the sealing plate 50, parallel to and abutting against the sealing plate 50. This arrangement can enhance the structural strength of the carton 100 in the second folded state.
[0074] Reference Figure 2 and Figure 7 , Figure 7 The schematic diagram of the carton 100 in a second folded state provided for other embodiments of this application shows that in some embodiments, the sealing plate 50 further includes a second wing plate 53 and a pair of third wing plates 54. The second wing plate 53 is located at the end of the sealing plate 51 away from the second enclosure 20, and a first wing plate 52 is connected between the second wing plate 53 and the second enclosure 20. The pair of third wing plates 54 are arranged opposite each other and spaced apart along a third direction Z, and the second wing plate 53 is connected between the pair of third wing plates 54.
[0075] For example, in the first folded state, the second wing plate 53 is folded 90° relative to the sealing plate 51 and is located inside the carton 100 and parallel to the second enclosure plate 20. The third wing plate 54 is folded 90° relative to the second wing plate 53 and is located inside the first wing plate 52 and parallel to the first wing plate 52, thereby strengthening the structure of the carton 100 in this state. In the second folded state, the first wing plate 52, the second wing plate 53, the third wing plate 54 are coplanar with the sealing plate 51 and together cover the opening of the carton 100. The carton 100 in the second folded state can be used as a regular carton 100, and the seams of the sealing plate 50 can be sealed with tape.
[0076] In some embodiments, in the unfolded state, the sealing plate 50, a pair of first enclosure plates 10, a pair of second enclosure plates 20, the fixing plate 40, and the folding plate 30 are coplanar.
[0077] In some embodiments, in the unfolded state, the carton 100 is a piece of cardboard, with the first side panel 10, the second side panel 20, the fixing plate 40, the folding plate 30, the first wing plate 52, the second wing plate 53, and the third wing plate 54 being coplanar. This arrangement can reduce the difficulty of manufacturing and transporting the carton 100.
[0078] Reference Figure 2In some embodiments, in the unfolded state, the first enclosure 10 and the second enclosure 20 are alternately arranged, from left to right as the left first enclosure, right first enclosure, front second enclosure, and rear second enclosure. The left first enclosure and the front second enclosure are connected by a folding plate 30, the right first enclosure and the rear second enclosure are connected by a folding plate 30, and the right first enclosure and the front second enclosure are connected by a folding plate 30. The folding plate 30 at the connection between the left first enclosure and the rear second enclosure is a split structure, that is, the first plate 31 and the second plate 32 are separate from each other. The second plate 32 is located on the far right and connected to the rear second enclosure, while the first plate 31 is located on the far left and connected to the left first enclosure.
[0079] Reference Figure 2 In some embodiments, the rightmost second plate 32 is further provided with an adhesive plate 70, the surface of which is coated with an adhesive. When folding the carton 100, the adhesive plate 70 can be connected to the leftmost first plate 31 firstly, so that the cardboard is connected end to end. Then, the folding or unfolding state of the folding plate 30 can be adjusted as needed to form the carton 100 in a first folded state or a second folded state. This arrangement can improve the folding efficiency of the carton 100.
