Description

Technical Field

[0001] The utility model relates to a folding carton, in particular to a carton cut piece and a carton with enhanced buffering. Background Art

[0002] Carton packaging is very commonly used in the storage and transportation of goods. In order to transport goods in batches, cartons often need to be stacked in batches. However, due to material limitations, the structural strength of existing cartons is not high. During the stacking process, the cartons are easily deformed due to impact.

[0003] For example, the "anti-theft carton packaging structure without adhesive tape or nails and its integrated cut piece" disclosed in Chinese patent documents has a publication number of CN212172874U, which includes a base plate and four side plates vertically arranged around the edge of the base plate, one of which has a swing cover corresponding to the base plate at the upper end, and a plurality of double-buckle anti-theft structures are arranged between the swing cover and the other side plates. The disadvantage of this patent is that the carton lacks a reinforced buffer structure, and once it is impacted during stacking, it is easy to deform, resulting in damage to the carton. Utility Model Content

[0004] The utility model aims to overcome the problem in the prior art that cartons are easily deformed and damaged by impact during stacking, and provides a carton cut piece and a carton with reinforced buffering, which can avoid deformation of the carton during stacking by adding a reinforced buffering structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model discloses a reinforced buffer carton cut piece, comprising a plurality of side panels connected in sequence, at least one of the side panels being a reinforced side panel, a reinforcing plate being connected to the reinforced side panel, the reinforcing plate comprising a side panel reinforcing portion and a folded corner reinforcing portion, a folded corner reinforcing pressure line being arranged between the side panel reinforcing portion and the folded corner reinforcing portion.

[0007] The reinforcing plate can be used to reinforce the side panels of the folded carton. The side panel reinforcement portion can form a double-layer structure on the side panel to strengthen it. The corner reinforcement portion can form a triangular support structure with the side panel to improve the cushioning effect against impact during stacking.

[0008] Preferably, the width of the reinforcing plate is greater than the width of the side plate connected thereto. This structure prevents the angled reinforcing plate from being directly attached to the reinforcing side plate, thereby facilitating the formation of an angle.

[0009] Preferably, a corner cutout is provided between the reinforcing side plate and the corner reinforcement part, wherein the corner cutout can form a gap between the folded corner reinforcement part and the upper cover of the carton to prevent the corner reinforcement part from affecting the sealing of the carton.

[0010] Preferably, a bending portion is provided between the reinforced side panel and the side panel reinforcement portion, a bending pressure line is provided at the connection between the bending portion and the reinforced side panel, and a bending pressure line is also provided at the connection between the bending portion and the side panel reinforcement portion. The bending pressure line enables the side panel reinforcement portion to rotate 180° and fit on the reinforced side panel.

[0011] Preferably, a reinforcing plate fixing plate is connected to the side of the reinforcing side plate opposite to the side connected to the reinforcing plate, and a reinforcing plate fixing opening is provided on the reinforcing plate fixing plate. The reinforcing plate fixing opening can be used to fix the reinforcing plate.

[0012] Preferably, the distance between the reinforcing plate fixing opening and the connection line between the reinforcing plate fixing plate and the reinforcing side plate is not less than 2 mm. This structure can form a certain angle between the side plate reinforcement part and the reinforcing plate, rather than completely fitting together, and the triangular structure formed by the angle further improves the strength.

[0013] Preferably, the reinforcing plate is provided with a fixing tongue adapted to the fixing opening of the reinforcing plate.

[0014] Preferably, at least one of the side panels is connected with a side panel connecting portion, which is used to connect the side panels to form a circle to form the side wall of the carton.

[0015] Preferably, the number of the side panels is four, and the four side panels include two reinforced side panels and two single-layer side panels, and the reinforced side panels and the single-layer side panels are spaced apart from each other.

[0016] A carton with enhanced cushioning is formed by folding the above-mentioned carton cut pieces. The strength is improved by designing the cut pieces, and the carton is formed by folding, and no assembly is required and the weight of the carton will not be increased.

[0017] Therefore, the utility model has the following beneficial effects: (1) deformation of the carton during stacking can be avoided by adding a reinforcing buffer structure; (2) strength is improved by designing the cut pieces, and the carton is formed by folding, and no assembly is required and the weight of the carton will not be increased.

[0034] exist Figure 1 In the figure, the dotted lines are all pressing lines, which are structures used for bending after molding, and the solid lines are all knife lines, which are structures that have been cut after die cutting.

[0035] by Figure 1 Taking the positional relationship in as an example, the left side of the left side panel 1 is connected with a side panel connecting portion 5, and the side panel connecting portion 5 is used to connect the left side panel 1 with the rear side panel 4, so that the cut pieces are connected end to end to form the side wall of the carton. The side panel connecting portion 5 can be bonded to the rear side panel 4 by glue. The right side of the left side panel 1 is connected to the front side panel 2, the upper side of the left side panel 1 is connected to the left cover plate 6, and the lower side of the left side panel 1 is connected to the left bottom plate 7.

[0036] The reinforcing plate includes a side plate reinforcing portion 14 and a corner reinforcing portion 15. Each reinforcing plate includes two corner reinforcing portions 15. The two corner reinforcing portions 15 are respectively located on both sides of the side plate reinforcing portion 14. A corner reinforcing pressure line is provided between the side plate reinforcing portion 14 and the corner reinforcing portion 15. The side plate reinforcing portion 14 can form a double-layer structure on the side plate to strengthen the side plate, and the corner reinforcing portion 15 can form a triangular support structure with the side plate to improve the buffering effect of the impact during stacking.

[0037] The width of the reinforcing plate is greater than the width of the side plate connected thereto, so that the angled reinforcing plate cannot be directly attached to the reinforcing side plate, thereby facilitating the formation of an angled corner.

[0038] A corner cutout 16 is provided between the reinforcing side plate and the corner reinforcement part 15. The corner cutout 16 can form a gap between the folded corner reinforcement part 15 and the upper cover of the carton to prevent the corner reinforcement part 15 from affecting the sealing of the carton.

[0039] A bending portion 17 is provided between the reinforcing side plate and the side plate reinforcing portion 14, a bending pressure line is provided at the connection between the bending portion 17 and the reinforcing side plate, and a bending pressure line is also provided at the connection between the bending portion 17 and the side plate reinforcing portion 14. The bending pressure line enables the side plate reinforcing portion 14 to rotate 180° and fit on the reinforcing side plate.

[0040] The reinforcing plate fixing plate is provided with a reinforcing plate fixing opening 18. The distance between the reinforcing plate fixing opening 18 and the connection line between the reinforcing plate fixing plate and the reinforcing side plate is not less than 2 mm, and the bending pressure line allows the side plate reinforcing portion 14 to rotate 180° and fit on the reinforcing side plate. The reinforcing plate is provided with a fixing tongue 19 adapted to the reinforcing plate fixing opening 18.

[0041] The following is the process of folding the carton pieces into cartons in this application:

[0042] like Figure 2 As shown, first lay the carton pieces flat on the work surface.

[0043] like Figure 3 As shown, at the connection position between the front side panel 2 and the right side panel 3, the front side panel 2 and other parts on the left side of the front side panel 2 are turned over as a whole, and the turning angle is 180°. After turning over, the left side panel 1 and the front side panel 2 cover the right side panel 3 and the rear side panel 4, and the side edge of the left side panel 1 is aligned with the side edge of the rear side panel 4. Then, glue is applied to the side panel connecting portion 5, and it is turned over relative to the left side panel 1, and the turned side panel connecting portion 5 is bonded to the rear side panel 4.

[0044] like Figure 4 As shown, keep the right side panel 3 in contact with the work surface, flip up the front side panel 2 and the rear side panel 4, and bend the left side panel 1 relative to the front side panel 2. In this process, a new fold is formed between the left side panel 1 and the front side panel 2, and a new fold is formed between the right side panel 3 and the rear side panel 4. The left side panel 1, the front side panel 2, the right side panel 3, and the rear side panel 4 are connected end to end to form a frame structure. At this time, a 90° angle is formed between two adjacent side panels of the left side panel 1, the front side panel 2, the right side panel 3, and the rear side panel 4.

[0045] like Figure 5As shown, the left bottom plate 7 and the right bottom plate 11 are bent 90 degrees toward the inner side of the formed frame structure so as to fill the bottom surface of the carton.

[0046] like Figure 6 As shown, the front bottom plate 9 and the rear bottom plate 13 are bent 90° toward the inner side of the formed frame structure, so as to fill the bottom surface of the carton. At this time, the bottom surface has been closed by four bottom plates, and the bottom plates can be fixed by tape, or they can be left unfixed and packaged after the carton is folded as a whole. After the bottom surface is filled, the carton is rotated as a whole and placed on the work surface with the bottom surface facing down.

[0047] like Figure 7 As shown, the corner reinforcement part 15 of the reinforcement plate is bent along the corner reinforcement pressure line, and the bending direction is toward the outside of the frame structure. This step is mainly used to form a fold between the corner reinforcement part 15 and the side plate reinforcement part 14, so there is no need to determine the bending angle.

[0048] like Figure 8 As shown, the front side reinforcing plate 8 is bent 180° toward the inner side of the frame structure, so that the side plate reinforcing portion 14 is close to the reinforcing side plate, and the fixing tongue 19 is inserted into the reinforcing plate fixing opening 18. At this time, the corner reinforcing portion 15 abuts against the single-layer side plate, and a triangular structure is formed between the corner reinforcing portion 15, the single-layer side plate, and the reinforcing side plate, thereby forming a buffer structure in the vertical direction.

[0049] like Fig. 9 As shown, the rear reinforcing plate 12 is also folded into the frame structure and fixed.

[0050] like Fig.10 As shown, the left cover plate 6 and the right cover plate 10 are bent 90° to form the upper cover of the carton. Fig.11 Carton shown.

[0051] A reinforced cushioning carton is formed by folding the above-mentioned carton cut pieces. The four corners of the inner side wall of the carton are provided with triangular reinforced cushioning structures. Two of the side walls of the carton form a double-layer structure.
