[0001] The utility model relates to the technical field of packaging, in particular to a connection structure of a color box. Background Art

[0002] Color boxes are folding cartons and micro-corrugated paperboard boxes made of cardboard and micro-corrugated paperboard. They are generally used as a mid-range packaging method, between inner packaging and outer box packaging. Color boxes are generally made of a combination of colors, giving people a strong visual sense, allowing buyers and users to understand the overall appearance and color details of the product.

[0003] Existing color boxes generally consist of a bottom panel, four side panels and a flip cover. The bottom panel and the side panels are vertically connected to each other and then enclosed by the flip cover to form a closed cavity. The side panels are fixed by folding and then using adhesive.

[0004] Since color boxes often involve transportation and handling during use, the corners of the color boxes are easily squeezed, resulting in deformation and affecting the appearance of the product.

[0005] Based on this, the present invention designs a connection structure for a color box to solve the above problems. Utility Model Content

[0007] By adopting the above technical solution, when folding the color box into a closed cavity, the first bending part and the second bending part can be folded first, and then the side panel can be rotated upward so that the folded second bending part and the accommodating plate are pressed against each other, and the guard plate 2 is fitted with the side panel, so that the guard plate 1 and the first folding part form a corner guard between the side panel and the bottom panel, thereby protecting the corners of the paper box body and enhancing the structural strength of the paper box.

[0008] Preferably, a self-adhesive sticker is provided on the second guard plate.

[0009] By adopting the above technical solution, the second guard plate and the side plate can be bonded together by adhesive, making the first guard plate and the first bending portion less likely to separate from the side plate, further increasing the stability of the paper box.

[0010] Preferably, a receiving groove is provided on the receiving plate.

[0011] By adopting the above technical solution, the folded second bent portion can be stuck in the accommodating groove, so that the second bent portion is less likely to be subjected to force and produce horizontal displacement, thereby increasing the stability of the structure.

[0012] Preferably, a limiting block is provided at the opening of the accommodating groove, and a limiting groove is provided on the side plate.

[0013] By adopting the above technical solution, when the second bending part is inserted into the accommodating groove, the limiting block on the accommodating groove will also be inserted into the limiting groove on the side panel, preventing the second bending part from easily moving in the vertical direction, thereby further increasing the stability of the paper box structure.

[0014] Preferably, an upper buckle plate and a lower buckle plate are respectively provided on both sides of the side panel.

[0015] By adopting the above technical solution for connecting the side panels, the buckling between the upper buckle plate and the lower buckle plate can not only ensure a stable connection between the side panels, but also enable the upper and lower buckle plates to press and support each other, making the corner support force between the side panels more stable.

[0016] Preferably, a waterproof layer is provided on the guard plate.

[0017] By adopting the above technical solution, the guard plate 1 will not soften due to moisture, thereby further enhancing the stability of the paper box body structure.

[0018] To sum up, the present application has the following beneficial technical effects: when folding the color box into a closed cavity, the first bending part and the second bending part can be folded first, and then the side panel can be rotated upward so that the folded second bending part and the accommodating plate are pressed against each other, and the guard plate 2 is fitted with the side panel, so that the outer side of the guard plate 1 and the first folding part form a corner guard between the side panel and the bottom panel, thereby protecting the corners of the paper box body and enhancing the structural strength of the paper box.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] A connection structure for a color box includes a paper box body, which consists of a bottom plate 5, four side plates 2 and a flip cover 1. A receiving plate 4 is fixedly provided on the bottom plate 5, and a receiving groove 41 is provided on the receiving plate 4. A connecting plate 3 is provided on the receiving plate 4. The side plates 2 are rotatably connected to the receiving plate 4 through the connecting plate 3. The connecting plate 3 includes a first bending portion 31, a second bending portion 32, a guard plate 1 33 between the first bending portion 31 and the bottom plate 5, and a guard plate 2 34 between the first bending portion 31 and the second bending portion 32. The receiving plate 4 is connected to the guard plate 1 33, and the guard plate 2 34 is provided with a self-adhesive sticker 341.

[0029] Before use, the color box is in an unfolded state, the four side panels 2 are connected to the four side edges of the bottom panel 5 , and the flip cover 1 is rotatably connected to one of the side panels 2 .

[0030] When in use, the side panel 2 is rotated upward so that the side panel 2 is rotated from a state parallel to the horizontal plane to a state close to perpendicular to the horizontal plane. After the rotation, the first bending portion 31 and the second bending portion 32 are folded so that the first bending portion 31 is parallel to the bottom plate 5. The second bending portion 32 is then rotated downward, and the side panel 2 is pressed downward so that the second bending portion 32 is stuck in the accommodating groove 41. At this time, the guard plate 2 34 is fitted with the side panel 2 through the adhesive 341, which supports and protects the side panel 2, making the connection between the side panel 2 and the bottom plate 5 more stable, protecting the edges and corners of the paper box body, and enhancing the structural strength of the paper box.

[0031] The self-adhesive label 341 provided on the second guard plate 34 is to make the second guard plate 34 fit more closely with the side panel 2, so that the first bending portion and the guard plate 1 33 can protect and support the side panel 2; a limiting block 35 is provided at the opening of the accommodating groove 41, and a limiting groove 36 is provided on the side panel 2. After the second bending portion 32 enters the accommodating groove 41, the accommodating groove 41 can limit the second bending portion 32 to prevent it from being displaced in the horizontal direction. At the same time, the limiting block 35 on the accommodating groove 41 will enter the limiting groove 36 on the side panel 2, so that the second bending portion 32 will not easily detach from the limiting groove 36, thereby further strengthening the structural strength of the paper box body.

[0032] An upper snap-fitting plate 21 and a lower snap-fitting plate 22 are respectively provided on both sides of the side panel 2. The upper snap-fitting plate 21 and the lower snap-fitting plate 22 are respectively provided with a snap-fitting groove. When the side panel 2 is rotated to be almost perpendicular to the bottom panel 5, the two adjacent side panels 2 are snapped together through the snap-fitting groove, so that a connection can be generated between the side panels 2. While ensuring that the items in the box will not fall out, the mutual pressure between the upper snap-fitting plate 21 and the lower snap-fitting plate 22 can be used to increase the supporting force of the paper box body.

[0033] A waterproof layer 331 is provided on the outside of the guard plate 33, so that the bottom plate 5 from the side in contact with the plane to the part of the connecting plate 3 that is not bent can be isolated from water, so that the bottom corner of the side panel 2 will not be softened due to moisture, further enhancing the stability of the paper box body structure.

[0034] When the folding plate 31 is in the upright position, the second folding plate 32 is in the upright position, and the folding plate 31 is in the upright position, so that the folding plate 31 is in the upright position, and the folding plate 31 is in the upright position, so that the folding plate 31 is in the upright position, and the folding plate 31 is in the upright position, so that the folding plate 31 is in the upright position, and the folding plate 31 is in the upright position, so that the folding plate 31 is in the upright position, and the folding plate 31 is in the upright position, so that the folding plate 31 is in the upright position, and the folding plate 31 is in the upright position, so that the folding plate 31 is in the upright position,

[0035] When the side panels 2 are rotated to be almost perpendicular to the bottom panel 5, the two adjacent side panels 2 are fastened together through the fastening grooves, so that a connection can be generated between the side panels 2. While ensuring that the items in the box do not fall out, the mutual pressure between the upper fastening plate 21 and the lower fastening plate 22 can be used to increase the supporting force of the carton body, making the connection between the side panels 2 and the bottom panel 5 more stable, protecting the edges and corners of the carton body, and enhancing the structural strength of the carton.
