[0024] 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.

[0025] Example 1:

[0026] An easy-to-open packaging box, such as Figures 1-6 As shown, it includes a side frame assembly and two groups of packaging assemblies. The two groups of packaging assemblies are symmetrically fixed on both sides of the side frame assembly, and the two ends of the side frame assembly are adhesively installed. The two groups of packaging assemblies respectively seal the open ends of the side frame assembly on both sides. One group of packaging assemblies is provided with a tearing assembly, which facilitates the opening of the packaging box. The side frame assembly and the packaging assembly are both made of cardboard, and the bent part of the cardboard is crimped to form a concave mark 9.

[0027] By bending the side frame assembly and gluing the two ends of the side frame assembly to form a square tube shape, two groups of packaging assemblies are packaged on both ends of the square tube-shaped side frame assembly to assemble a hexahedral packaging box. The packaging box is simple to fold and assemble. One group of packaging assemblies is provided with a tearing assembly, which is convenient for tearing the packaging assembly. The packaging assembly is torn into two parts, making the packaging box easy to open. The packaging box is made of cardboard, and the side frame assembly and the packaging assembly are integrated. When the packaging box is folded and assembled, the cardboard is bent, and the gravure 9 facilitates the bending of the cardboard.

[0028] A plurality of groups of holes can be opened on the side frame assembly to form an elliptical shape. The cardboard in the elliptical holes can be removed to facilitate the picking up and carrying of the packaging box. Paper can also be placed in the packaging box. The torn packaging box surface can be resealed with tape and the paper can be pulled out through the elliptical holes. The packaging box has more functions and its utilization value is increased.

[0029] like Figure 1-Figure 3 As shown, the side frame assembly includes four groups of side portions 1, which are fixed in sequence. Each group of packaging assembly includes a group of outer folding portions 4, two groups of inner folding portions 3 and a group of packaging portions 5. The outer folding portions 4, the inner folding portions 3 and the packaging portions 5 are respectively fixed to the four groups of side portions 1. The packaging portion 5 is located between the two groups of inner folding portions 3, and the outer folding portion 4 is located outside the two groups of inner folding portions 3.

[0030] The four groups of side portions 1 are fixedly connected in sequence to form a long strip. When the two groups of side portions 1 at the two ends are bonded and the adjacent side portions 1 are bent at 90 degrees, the four groups of side portions 1 can be folded into a square tube to form the side structure of the packaging box. There is a group of outer folding portions 4, two groups of inner folding portions 3 and a group of sealing portions 5 on both sides of the side frame assembly. When folding the paper box, the inner folding portions 3 at both ends of the square tube-shaped side frame are folded first, then the outer folding portions 4, and then the sealing portions 5, so that the inner folding portions 3, the outer folding portions 4 and the sealing portions 5 seal the two ends of the packaging box, and the folding directions of the inner folding portions 3 and the outer folding portions 4 are perpendicular.

[0031] like Figure 1-Figure 3 As shown, one end of the side frame assembly is fixed with a side connecting portion 2, and the side connecting portion 2 is bonded and installed to the other end of the side frame assembly, so that the two ends of the side frame assembly are bonded and installed, and the two sets of packaging portions 5 are bonded with an adhesive layer 6, and the adhesive layer 6 is bonded and installed to the outer folding portion 4.

[0032] Along the side frame assembly, starting from the side connecting portion 2, the side walls of the side frame assembly are the outer folding portion 4, the inner folding portion 3, the packaging portion 5, and the inner folding portion 3 in sequence. The inner folding portion 3 is folded first, then the outer folding portion 4 is folded, and finally the packaging portion 5 is folded so that the adhesive layer 6 of the packaging portion 5 is bonded to the outer folding portion 4.

[0033] like Figure 1-Figure 3 As shown, the tearing assembly includes two groups of tearing ends 7, which are respectively fixed to both sides of the packaging part 5, and a tearing tape 8 is bonded between the two groups of tearing ends 7, and the tearing tape 8 is bonded to the packaging part 5.

[0034] When the packaging part 5 is bonded to the outer folding part 4, the tear tape 8 is located on the side of the packaging part 5 close to the outer folding part 4. By pinching the tear end 7, the tear tape 8 can be torn, thereby dividing the packaging part 5 into two parts, making the packaging box easy to open.

[0035] Example 2:

[0036] like Figure 5-Figure 6As shown, a slit 10 is opened in the middle of the cardboard, and a fixing layer 11 is bonded to the positions corresponding to the two sides of the gravure 9 inside the slit 10, and multiple groups of cotton threads 12 are fixed between the two groups of fixing layers 11. A filling layer 16 is bonded to the position between the two groups of fixing layers 11 inside the slit 10, and multiple groups of cotton threads 12 are all located inside the filling layer 16. A bending layer 13 is bonded to the inside of the slit 10, and the shape of the bending layer 13 is set to be wavy.

[0037] The bending layer 13 is composed of multiple groups of triangular structures, which has good anti-punching effect and makes the inside of the gap 10 non-solid, reducing the weight of the packaging box. The filling layer 16 increases the thickness of the bending part. The filling layer 16 can be made of paper material to avoid the cardboard being too weak with only cotton thread 12 at the bending part. Cotton thread 12 is set inside the bending part of the packaging box. The cotton thread 12 is perpendicular to the bending line and spans a certain length on both sides of the bending line to protect each bending part.

[0038] When the cardboard is bent, the cotton thread 12 inside the cardboard increases the toughness of the bend. Even if the cardboard breaks at the bend, the cotton thread 12 will keep the broken surface of the carton from separating. The fixing layer 11 will bond and fix the cotton thread 12 inside the cardboard. The position of the cotton thread 12 corresponds to the position of the bend of the cardboard, which prevents the cardboard from drying out and breaking, and also prevents the cardboard from getting wet and causing holes, thereby reducing the loss rate of the carton.

[0039] The cardboard structure can also be made of a three-layer structure, with two smooth paper layers and a layer of wavy corrugated paper. The smooth paper layer and the wavy corrugated paper are glued on both sides, and cotton thread 12 is pre-glued and fixed in the area that needs to be bent to form a cardboard with a larger area. The cardboard is then cut according to the pre-installed cotton thread 12, and the cut cardboard is embossed with a gravure print 9. The cardboard is bent to form a packaging box. In both cardboard production methods, cotton thread 12 is glued inside to protect the bent part of the packaging box.

[0040] like Figure 4 As shown, corner brackets 14 are bonded and installed at the corners inside the side frame assembly, and the corner brackets 14 are made of cardboard.

[0041] The corner bracket 14 is a right-angle structure formed by bending cardboard and can be made of residual scraps of the packaging box. It is glued to the inner corner of the packaging box before packaging to increase the anti-extrusion ability of the packaging box corner and prevent the packaging box corner from deformation and damage.

[0042] The working principle of the easy-to-open packaging box provided by the utility model is as follows:

[0043] The packaging box is composed of a group of side frame components and two groups of packaging components. The side frame components are bent and the two ends of the side frame components are bonded to form a cylindrical shape, forming the side of the packaging box. The two groups of packaging components seal the two ends of the cylindrical side frame components to form a hexahedral packaging box. The packaging box is simple to fold and assemble. A tearing component is provided on one group of packaging components to facilitate tearing the packaging component, making the packaging box easy to open. The packaging box is made of cardboard, and the side frame components and the packaging component are integrated. When the packaging box is folded and assembled, the cardboard is bent, and the gravure 9 facilitates the bending of the cardboard.
