Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically a color box with a three-dimensional folding structure. Background Technology

[0002] Packaging boxes refer to folding or micro-corrugated cardboard boxes made from two materials: cardboard and micro-corrugated paperboard. The materials used in packaging boxes can be divided into two main categories: linerboard and corrugated paper.

[0003] However, the existing technology has the following drawbacks:

[0004] Currently, most color boxes on the market have a relatively simple structure, typically consisting of a basic box. During use, they lack a three-dimensional feel and visual appeal, failing to meet consumers' demands for aesthetically pleasing and unique product packaging. Furthermore, existing color boxes occupy a significant amount of space during transportation and storage, hindering the reduction of transportation and storage costs. Utility Model Content

[0005] The purpose of this utility model is to provide a color box with a three-dimensional folding structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a color box with a three-dimensional folding structure, including a top cover, a protective sleeve, and a bottom plate. Second side plates are fixedly installed at both the front and rear ends of the bottom plate, and a folding line is provided at the connection between the two. First side plates are fixedly installed at both the left and right ends of the bottom plate, and a folding line is provided at the connection between the two. An extension plate is fixedly installed in the middle of the side of the first side plate away from the bottom plate, and a folding line is provided at the connection between the two. Second fixing straps are provided at both ends of the side of the extension plate away from the first side plate. A third male buckle is fixedly installed on the outer side of the second fixing strap away from the extension plate. A first groove is formed in the inner wall of the middle of both sides of the second side plate, and a first female buckle is fixedly installed inside the first groove. The third male buckle is engaged with the first female buckle. The bottom of one side of the top cover is hinged to the middle of the top of one of the second side plates via a leather hinge.

[0007] Using the above technical solution, the base plate, first side plate, second side plate, and top cover are integrally formed and fixedly connected. They are folded into a box shape through folding and snap fasteners.

[0008] The inner walls of the top of both sides of the first side plate are fixedly installed with third female buckles, and the two ends of the extension plate near the first side plate are fixedly installed with first male buckles. The first male buckles are fastened to the third female buckles, and the side of the extension plate with the first male buckle is in close contact with the inner wall of the top of the first side plate.

[0009] The above technical solution involves folding the extension plate so that it is located inside the first side panel, and then fixing it to the first side panel with the first male buckle and the third female buckle to prevent it from popping open and affecting the items stored in the box.

[0010] The inner walls of the second side plate are symmetrically provided with first fixing straps at the middle and bottom of both sides, and a second male buckle is fixedly installed on the outer side of the first fixing strap away from the second side plate. The inner walls of the first side plate are provided with second grooves at the middle and bottom of both sides, and a second female buckle is fixedly installed inside the second groove. The second male buckle and the second female buckle are fastened together.

[0011] By adopting the above technical solution, the second male buckle and the second female buckle strengthen the connection between the first side plate and the second side plate, and prevent the box from falling apart.

[0012] Both sides of the first side plate and both sides of the second side plate are 45-degree slopes, and the two sides are tightly fitted together. The first and second fixing straps are both made of rubber. The height of the first side plate and the height of the second side plate are the same. A second handle is provided in the middle of the top outer side of the first side plate.

[0013] Using the above technical solution, the rubber material is soft, flexible and foldable, yet tough to prevent breakage, and the second handle makes it easy to carry and transport the color box.

[0014] The extension plate is shorter than the length of the first side plate, and after the extension plate is folded, a slot is formed between it and the second side plate. The bottom of the top cover has a protrusion on the side away from the hinge, and the protrusion is engaged and installed inside the slot. The top cover has a first handle in the middle of the side away from the hinge.

[0015] Using the above technical solution, the protruding strip is installed in the empty groove, the connection is tight, and the top cover is prevented from loosening, thus achieving a tight connection between the top cover and the box body.

[0016] The outer walls on both sides of the first side plate and the outer walls on both sides of the second side plate are respectively provided with a second sliding groove and a first sliding groove. The inner walls of the two side plates of the protective sleeve are respectively provided with a first sliding strip and a second sliding strip. The first sliding strip and the second sliding strip are respectively inserted into the interior of the first sliding groove and the second sliding groove.

[0017] The above technical solution involves inserting the first and second slide bars into the first and second slide grooves and fitting them around the four edges of the box, thus providing protection and enhancing the stability of the structure.

[0018] The protective sleeve has an L-shaped top cross-section and a rectangular bottom plate. A rubber pad is adhered to the bottom of the protective sleeve. Circular grooves are provided at the four corners of the bottom of the bottom plate. Circular protrusions are provided on the top of the rectangular plate of the protective sleeve and are engaged in the circular grooves.

[0019] The above technical solution uses a protective sleeve that is installed in a circular groove by a protrusion, which serves to fix the sleeve in place and prevent it from falling off.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The color box of this utility model is designed with an extension plate and snaps. When folded, the snaps are fastened to fix the box, making the structure of the color box more stable and forming a three-dimensional shape, which enhances the display effect. The protrusion at the bottom of the top cover can be inserted into the gap between the extension plate and the second side plate, which can achieve a stable connection between the top cover and the box body, prevent the top cover from being opened accidentally, and protect the contents of the box.
