Description

Technical Field

[0001] This utility model relates to the field of packaging box folding technology, specifically a color-printed packaging box that is easy to fold. Background Technology

[0002] Color box packaging printing involves many industries, such as cosmetic boxes, medicine boxes, health product boxes, wine boxes, tea boxes, food boxes, etc. Different types of paper and processes result in different grades and prices for packaging boxes. White cardboard, white board paper, and grey board paper are commonly used in the market. Higher-end packaging, such as cosmetic boxes and wine boxes, uses special paper. When transporting and collecting packaging boxes, they need to be folded to reduce their floor space, hence the provision of a convenient foldable color printed packaging box.

[0003] For example, the side of the box with announcement number "CN219565804U" is made of thinner paper and reinforced with four reinforcing beams. This allows it to combine the pressure and deformation resistance of a thick, rigid packaging box with the low production cost of a thin one. When folded, the softer, more easily damaged side is completely enclosed inside, providing protection for the weaker parts of the box. However, as described above, assembling the box requires aligning the reinforcing beams with the four corners of the bottom, peeling off the protective film, and then attaching the reinforcing beams using adhesive. The reinforcing beams are then used to secure the side. This assembly process is quite cumbersome. Furthermore, the adhesive is a disposable product; after assembly, when disassembly is needed, impurities and dust will adhere to the adhesive, reducing its stickiness. This makes it inconvenient for multiple folds and assemblies, resulting in lower practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the assembly process of aligning the reinforcing parts with the four corners of the box bottom, peeling off the protective film, and then using an adhesive layer to attach the reinforcing parts and fix the sides is cumbersome. In addition, the adhesive layer is a disposable product. After assembly, when it is necessary to disassemble, the adhesive layer will be covered with impurities and dust, which will reduce its viscosity. Therefore, it is not convenient to perform multiple folds and assembly, resulting in low practicality. Therefore, a color-printed packaging box that is easy to fold is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a foldable color-printed packaging box, including a box bottom and side panels. The upper end of the outer wall of the box bottom is rotatably connected to multiple side panels through creases. A box lid is fastened to the upper end of the outer wall of the side panels. Packaging box support structures are provided at the four corners of the inner wall of the box bottom.

[0007] Preferably, the packaging box supporting structure comprises a base, the inner wall of the base is inserted with a vertical rod, the upper end of the inner wall of the front and rear side plates is fixedly connected with a first clamping jaw, the upper end of the outer wall of the left and right side plates is fixedly connected with a second clamping jaw, and the inner wall of the first clamping jaw and the second clamping jaw is attached to the vertical rod.

[0008] Preferably, the lower end of the outer wall of the base is fixedly connected with a box bottom.

[0009] Preferably, through holes are formed on both sides of the box bottom.

[0010] Preferably, wear-resistant layers are fixedly connected to the outer walls of the box bottom, the side plates and the box cover.

[0011] The packaging box supporting structure comprises a base, the inner wall of the base is inserted with a vertical rod, the upper end of the inner wall of the front and rear side plates is fixedly connected with a first clamping jaw, the upper end of the outer wall of the left and right side plates is fixedly connected with a second clamping jaw, and the inner wall of the first clamping jaw and the second clamping jaw is attached to the vertical rod.

[0019] The utility model will be further described below with reference to the drawings:

[0020] Referring to the drawings Figures 1-6 In this embodiment, a color printing packaging box convenient to fold includes box bottom 5 and side plate 2, and the outer wall upper end of box bottom 5 is fixedly connected with multiple side plates 2 through creases, and the connecting place of box bottom 5 and side plate 2 is processed with a bending groove, the outer wall upper end of side plate 2 is buckled with box cover 4, the inner wall four corners of box bottom 5 are each provided with packaging box supporting structure 1, the outer wall lower end of base 103 is fixedly connected with box bottom 5, the both sides of box bottom 5 are processed with through hole 6, and the outer walls of box bottom 5, side plate 2 and box cover 4 are all fixedly connected with wear-resistant layer 3, box cover 4, side plate 2 and box bottom 5 all adopt plastic material with certain elasticity, wear-resistant layer 3 adopts polyvinyl chloride (PVC) material, and has higher wear resistance.

[0021] Referring to the drawings Figures 2-6 Packaging box supporting structure 1 includes base 103, the inner wall of base 103 is inserted with vertical rod 101, the inner wall upper end of front and rear side plate 2 is fixedly connected with first clamping jaw 102, the outer wall upper end of left and right side plate 2 is fixedly connected with second clamping jaw 104, the inner walls of first clamping jaw 102 and second clamping jaw 104 are attached with vertical rod 101, and first clamping jaw 102 and second clamping jaw 104 are plastic material with certain elasticity.

[0022] Working principle:

[0023] Color printing packaging box folding and assembling work:

[0024] When producing the packaging box, the outer walls of box cover 4, side plate 2 and box bottom 5 can be sprayed or printed, after the paint is air-dried, box cover 4, side plate 2 and box bottom 5 are pasted with wear-resistant layer 3, wear-resistant layer 3 adopts polyvinyl chloride (PVC) material, has higher wear resistance, a plurality of first clamping jaws 102 and second clamping jaws 104 are fixed on the upper end of side plate 2 by using hot melt adhesive, the both sides of box bottom 5 are processed with through hole 6 for ventilation and carrying, after production is completed, box cover 3 is taken down and covered at the lower end of base 5, then vertical rod 101 is laid down and placed in base 5, then a plurality of side plates 2 are sequentially folded clockwise inwards, the occupied space is reduced, a plurality of vertical rods 103 are packed by disposable packaging bags, the box body is composed of box cover 4, side plate 2 and box bottom 5, so that the packaging box can be folded by such movement;

[0025] When the packaging box needs to be assembled, the plurality of side plates 2 are unfolded outward to be vertical, and the plurality of side plates 2 are abutted, at this time, the first clamping jaw 102 and the second clamping jaw 104 are corresponding to the inner grooves, then the plurality of vertical rods 101 are taken out, and the vertical rod 101 is corresponding to the flared first clamping jaw 102 and the second clamping jaw 104 of the inner fixed corner of the side plate 2, the vertical rod 101 is pressed inward to be clamped in the first clamping jaw 102 and the second clamping jaw 104, at this time, the first clamping jaw 102 and the second clamping jaw 104 are expanded outward to be deformed, when the vertical rod 101 is clamped, the first clamping jaw 102 and the second clamping jaw 104 are retracted, so that the first clamping jaw 102 and the second clamping jaw 104 are limited by the vertical rod 101, then the subsequent vertical rod 101 is clamped in the remaining plurality of groups of clamping jaws 102, the clamping jaw 102 is made of plastic material and has a certain elasticity, then the vertical rod 101 is pushed downward to be inserted into the base 103, so that the vertical rod 101 is limited by the movement, and the side plate 2 is limited by the vertical rod 101 and the clamping jaw 102, the box cover 4 is further buckled on the upper end of the plurality of side plates 2, so that the packaging box can be assembled,
