[0040] Please see Figures 1 to 3 , Figure 1 is a structural schematic diagram of a carton 1 in an unfolded state disclosed by an embodiment of the present application, Figure 2 isFigure 1 Fig. 2 is a schematic view of the structure of the carton 1 in a folded completed state, Figure 3 is Figure 1 Fig. 3 is a schematic view of the folding part 121 of the carton 1 in the folding process. The embodiments of the present application disclose a carton 1, the end part of which is of a double-layer structure, so that the structural reliability can be improved.

[0041] Please refer to Figures 1 to 5 In a first aspect, the embodiments of the present application provide a carton 1, comprising a main part 11 and a reinforcing part 12, the reinforcing part 12 comprising a folding part 121, an edge part 122 and a folding lug part 123, the folding part 121 being folded to form a double-layer transverse extension part 1211 and a vertical extension part 1212, one end of the vertical extension part 1212 being connected to the transverse extension part 1211, the inner layer of the other end of the vertical extension part 1212 being connected to the edge part 122, the outer layer of the other end of the vertical extension part 1212 being connected to the end part of the main part 11, a first longitudinal indentation 124 being arranged at the connection between the vertical extension part 1212 and the main part 11, the connection between the vertical extension part 1212 and the edge part 122 being arranged overlapping the first longitudinal indentation 124, and the edge part 122 and the main part 11 being arranged in a stack, the transverse extension part 1211 and the edge part 122 being located on the same side of the vertical extension part 1212, the folding lug part 123 comprising a first connecting lug 1231 and a second connecting lug 1232 arranged in a stack, the first connecting lug 1231 being connected to the end part of the transverse extension part 1211, and the second connecting lug 1232 being connected to the end part of the vertical extension part 1212.

[0042] The carton 1 provided in this embodiment forms a double-layered horizontal extension 1211 and a vertical extension 1212 by folding the folding portion 121 of the reinforcing portion 12. One end of the vertical extension 1212 is connected to the horizontal extension 1211, the inner layer of the other end of the vertical extension 1212 is connected to the edge portion 122, and the outer layer of the other end of the vertical extension 1212 is connected to the end of the main body portion 11. The edge portion 122 of the reinforcing portion 12 is stacked with the main body portion 11 to form a double-layered C-shaped structure at the end of the main body portion 11. This helps to improve the longitudinal edge strength of the carton 1, thereby improving the structural reliability of the carton 1. At the same time, the first connecting ear 1231 and the second connecting ear 123 of the folding ear portion 123 are connected together. The 232-layer stacking arrangement forms at least a double-layer covering structure at the end of the folded portion 121, which helps to strengthen the end strength of the folded portion 121, i.e., improves the strength of the transverse and vertical edges of the carton 1. At this time, the three surfaces where the right-angle intersection of the folded portion 121 and the ear flap 123 connects are all double-layered structures, which helps to improve the strength of the right-angle positions of the carton 1, thereby further improving the structural reliability of the carton 1, increasing its impact resistance, enhancing its protection of the product's corners, improving safety during transportation, and preventing tearing or damage to the edges or right-angle positions of the carton 1 due to bumps during transportation. This reduces packaging cost waste caused by damage to the carton 1, thus lowering packaging costs. Therefore, using the carton 1 provided in this application, it is not necessary to fill the carton 1 with filler material or use a high-quality carton 1. By setting a double-layer structure at the end of the carton 1, structural reliability can be ensured, thereby achieving both reduced packaging costs and effective product protection.

[0043] Among them, horizontal refers to Figures 1 to 3 In the x-direction, the longitudinal direction refers to... Figure 1 , Figure 2 as well as Figures 4 to 5 In the y-direction, vertical refers to Figures 3 to 5 The z-direction in the structure. The inner layer refers to the layer closest to the center of the carton 1 (i.e., the layer wrapped inside the carton 1), and the outer layer refers to the layer furthest from the center of the carton 1 (i.e., the layer located outside the carton 1). The inner side refers to the side closest to the center of the carton 1, and the outer side refers to the side furthest from the center of the carton 1.

[0044] In some embodiments, the main body 11 is folded inward to form a hollow portion, and the lateral extension 1211 and the folded ear 123 extend into the hollow portion. This allows the folded portion 121 to have a partially overlapping structure with the main body 11, resulting in a multi-layered structure at the end of the main body 11. This improves the strength of the end of the main body 11, thereby enhancing the structural reliability of the carton 1 and preventing damage from impacts during packaging and transportation.

[0045] Optionally, the main body part 11 comprises a bottom plate 111, a first side plate 112, a second side plate 113, a first top plate 114 and a second top plate 115, the bottom plate 111 is connected to the vertical extension part 1212, the first longitudinal indentation 124 is located at the connection between the bottom plate 111 and the vertical extension part 1212, the first side plate 112 is connected to one side of the bottom plate 111 and extends vertically, the second side plate 113 is connected to the other side of the bottom plate 111 and extends vertically, the first top plate 114 is connected to the end of the first side plate 112 away from the bottom plate 111, the second top plate 115 is connected to the end of the second side plate 113 away from the bottom plate 111, the first top plate 114 and the second top plate 115 extend towards each other, and the connection between the first top plate 114 and the second top plate 115 is openable and closable to open or close the carton 1, the bottom plate 111, the first side plate 112, the second side plate 113, the first top plate 114 and the second top plate 115 enclose a hollow part, so that the main body part 11 and the reinforcing part 12 can be assembled to form the openable and closable carton 1, thereby facilitating the packing of the carton 1.

[0046] Optionally, the fold ear part 123 is arranged in a stack with the first side plate 112 and / or the second side plate 113, that is, when the number of fold ear parts 123 is one, the fold ear part 123 is arranged at the end of the folding part 121 close to the first side plate 112 to be stacked with the first side plate 112, or the fold ear part 123 is arranged at the end of the folding part 121 close to the second side plate 113 to be stacked with the second side plate 113, or when the number of fold ear parts 123 is two, one of the fold ear parts 123 is connected to the end of the folding part 121 close to the first side plate 112 and stacked with the first side plate 112, and the other fold ear part 123 is connected to the end of the folding part 121 close to the second side plate 113 and stacked with the second side plate 113. Thus, the carton 1 has a structure of at least three layers at the end of the first side plate 112 and the second side plate 113, which is beneficial to improve the strength of the end of the main body part 11 and improve the structural reliability of the carton 1.

[0047] Optionally, the connection between the bottom plate 111 and the first side plate 112 and the connection between the bottom plate 111 and the second side plate 113 are provided with third transverse indentations 116, and the connection between the first side plate 112 and the first top plate 114 and the connection between the second side plate 113 and the second top plate 115 are provided with fourth transverse indentations 117. Thus, the main body part 11 is formed by folding a single piece of paperboard, which has greater strength than a main body part 11 assembled by bonding, thereby improving the transverse edge strength of the carton 1 and improving the structural reliability of the carton 1, while also facilitating the simplification of the manufacturing process and improving the packaging efficiency.

[0048] It can be understood that, in other embodiments, the bottom plate 111 and the first side plate 112 and the second side plate 113, and the first side plate 112 and the first top plate 114, and the second side plate 113 and the second top plate 115 can also be connected by means of adhesive tape, glue or adhesive.

[0049] For example, when the folding part 121 is folded, first, the bottom plate 111 is laid flat, the first side plate 112 and the second side plate 113 are respectively folded upward by 90° along the third transverse crease 116, and then the first top plate 114 and the second top plate 115 are folded inward by 90° along the fourth transverse crease 117, thereby forming a C-shaped structure on both sides of the bottom plate 111.

[0050] Optionally, the number of third transverse creases 116 can be multiple, and multiple third transverse creases 116 are arranged at intervals near the connection between the bottom plate 111 and the first side plate 112 and the connection between the bottom plate 111 and the second side plate 113, so as to facilitate the control of the folding position of the bottom plate 111 and the first side plate 112 and the second side plate 113. By controlling the folding of the first side plate 112 and the second side plate 113 using different third transverse creases 116, the longitudinal dimension of the bottom plate 111 can be adjusted, so that the carton 1 can be folded using different third transverse creases 116 according to different sizes of the plate member, so as to adapt to the packaging of different sizes of the plate member, thereby expanding the application range of the carton 1, facilitating the unified production and manufacturing of the carton 1, and improving the packaging efficiency.

[0051] Optionally, the height of the first side plate 112 and the second side plate 113 is the same as or approximately the same as the height of the vertical extension 1212, the first connecting lug 1231 and the second connecting lug 1232, thereby improving the structural reliability of the end of the carton 1 in the vertical direction.

[0052] It can be understood that, in other embodiments, the height of the first side plate 112 and the second side plate 113 can also be greater than the height of the vertical extension 1212, the first connecting lug 1231 and the second connecting lug 1232.

[0053] In some embodiments, the end of the transverse extension 1211 away from the vertical extension 1212 is provided with a second longitudinal crease 125, the transverse extension 1211 is folded along the second longitudinal crease 125 to form a double-layer structure, the connection between the inner layer of the vertical extension 1212 and the transverse extension 1211 is provided with a third longitudinal crease 126, the connection between the outer layer of the vertical extension 1212 and the transverse extension 1211 is provided with a fourth longitudinal crease 127, and the third longitudinal crease 126 and the fourth longitudinal crease 127 are arranged correspondingly.

[0054] In this way, the folding part 121 is formed by folding a single piece of paperboard, which can have greater strength than the folding part 121 assembled by bonding, so as to improve the longitudinal edge strength of the carton 1, avoid the longitudinal edge of the carton 1 from being torn or damaged due to bumps during packaging and transportation, and improve the structural reliability of the carton 1. In addition, the folding part 121 is formed by folding a single piece of paperboard through multiple creases, and the gap between the two layers of the folding part 121 is small, which is conducive to improving the strength of the folding part 121, further improving the edge strength of the carton 1, and improving the structural reliability of the carton 1.

[0055] Optionally, a fifth longitudinal crease 128 is arranged at the connection between the edge part 122 and the vertically extending part 1212, and the fifth longitudinal crease 128 is arranged corresponding to the first longitudinal crease 124. In this way, the edge part 122 is formed into a double-layer structure by being folded and stacked with the main body part 11, which can improve the strength of the bottom (or top) and edges of the carton 1, and form a double-layer C-shaped structure at the end of the carton 1 by folding, so as to improve the strength of the carton 1 and simplify the manufacturing process and improve the packaging efficiency.

[0056] It can be understood that in other embodiments, the vertically extending part 1212 and the transversely extending part 1211, the edge part 122 and the bottom plate 111 can also be connected by means of adhesive tape, glue or adhesive.

[0057] For example, when the folding part 121 is located at the right end of the main body part 11, in some embodiments, when folding the folding part 121, the flat carton 1 is first folded along the second longitudinal crease 125, at this time the third longitudinal crease 126 corresponds to the fourth longitudinal crease 127, and the fifth longitudinal crease 128 corresponds to the first longitudinal crease 124, then the transversely extending part 1211 is folded counterclockwise by 90° along the third longitudinal crease 126, and then the vertically extending part 1212 is folded counterclockwise by 90° along the fifth longitudinal crease 128, thereby forming a double-layer C-shaped structure at the end of the main body part 11.

[0058] It should be noted that in other embodiments, the vertically extending part 1212 can be folded first, and then the transversely extending part 1211 is folded.

[0059] Optionally, a first adhesive material is arranged between the edge part 122 and the bottom plate 111, so that the edge part 122 and the bottom plate 111 can maintain a flat stacking effect, improve the structural stability of the carton 1, control the gap between the edge part 122 and the bottom plate 111, and improve the resistance to external force, thereby improving the structural reliability of the carton 1.

[0060] Optionally, the first cementing material can be any one of glue, adhesive, adhesive tape, double-sided tape, etc., which can be set according to actual needs, and is not limited here.

Thus, the depth of the indentation can be increased, so as to facilitate the indentation to remain for a longer time, to meet the long-term stock preparation of the carton 1, and at the same time facilitate the folding of the carton 1 along the indentation, and improve the packaging efficiency.

[0088] Optionally, the indentation groove includes a transverse indentation groove 2101 and a longitudinal indentation groove 2102, the transverse indentation groove 2101 is used for pressing a transverse indentation on the carton 1, and the longitudinal indentation groove 2102 is used for pressing a longitudinal indentation on the carton 1.
