The opposite two side edges of the bottom plate are respectively connected to one side edge of the two side plates. One side edge of the top plate is connected to the opposite side edge of one of the side plates. The opposite side edge of the other side plate is provided with a tongue, the outer surface of which can be connected to the inner surface of the opposite side edge of the top plate. Two lower flaps are respectively connected to the opposite two end edges of the bottom plate, two upper flaps are respectively connected to the opposite two end edges of the top plate, and two side flaps are respectively connected to the opposite two end edges of the side plates. The inner surfaces of the upper flaps and the lower flaps can be connected to the outer surfaces of the two side flaps on the same side. Each side plate is provided with an easy-tear strip, the two ends of which extend outward to the two end edges of the two side flaps away from the side plate. The two ends of the easy-tear strip can be exposed after the lower flap is connected to the two side flaps on the same side.

[0005] In a preferred embodiment of the present invention, two notches are provided at the end edge of the side cover away from the side plate and on both sides of the easy-tear strip. Two tear guide lines are also provided on the side cover and on both sides of the easy-tear strip, with one end of each tear guide line connected to the two notches.

[0006] In a preferred embodiment of this utility model, the bottom plate, top plate, and side plates are all rectangular plates. The two long edges of the bottom plate are connected to one of the long edges of the two side plates, and one of the long edges of the top plate is connected to the other long edge of one of the side plates. The tongue edge is connected to the other long edge of the other side plate. The two lower flaps are connected to the two short edges of the bottom plate, and the two upper flaps are connected to the two short edges of the top plate. The two side flaps corresponding to each side plate are connected to the two short edges of the side plate.

[0007] In a preferred embodiment of this utility model, the length direction of the tear strip is parallel to the connection line between the bottom plate and the side plate.

[0008] In a preferred embodiment of this utility model, the distance between the easy-tear tape and the opposite two edges of the base plate may be the same or different.

[0009] In a preferred embodiment of this utility model, the upper flap, the lower flap, and the side flap are all rectangular covers.

[0010] In a preferred embodiment of the present invention, beveled or rounded corners are formed at the two corners of the side flap away from the side plate.

[0011] In a preferred embodiment of this utility model, the bottom plate and the top plate are the same size, the sum of the widths of the two side flaps on the same side is less than the width of the bottom plate, and the sum of the widths of the upper flap and the lower flap on the same side is equal to the width of the side plate.

[0012] In a preferred embodiment of this utility model, the two side plates can be folded upward toward the bottom plate, the top plate can be folded toward the side near the tongue, each side flap can be folded inward, the lower flap can be folded upward, and the upper flap can be folded downward; indentation lines are provided at the folding positions between the two side plates and the bottom plate, the folding positions between the top plate and the corresponding side plates, the folding positions between the tongue and the corresponding side plates, the folding positions between each side flap and the corresponding side plates, the folding positions between each upper flap and the top plate, and the folding positions between each lower flap and the bottom plate.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, this embodiment provides an easy-tear packaging box, including a bottom plate 1, a top plate 2, and two side plates 3. The opposite two side edges of the bottom plate 1 are respectively connected to one side edge of the two side plates 3. One side edge of the top plate 2 is connected to the other opposite side edge of one of the side plates 3. A tongue 31 is provided on the other opposite side edge of the other side plate 3, and the outer surface of the tongue 31 can be connected to the inner surface of the other opposite side edge of the top plate 2. Two lower flaps 11 are respectively connected to the opposite two end edges of the bottom plate 1, and the opposite two end edges of the top plate 2 are respectively connected to the bottom plate 1. Two upper flaps 21 are connected to the edge of the side plate 3 respectively, and two side flaps 32 are connected to the opposite ends of the side plate 3 respectively. The inner surface of the upper flap 21 and the inner surface of the lower flap 11 can be connected to the outer surface of the two side flaps 32 on the same side. Each side plate 3 is provided with an easy-tear strip 33. The two ends of the easy-tear strip 33 extend outward to the two ends of the two side flaps 32 away from the edge of the side plate 3. The two ends of the easy-tear strip 33 can expose the lower flap 11 after it is connected to the two side flaps 32 on the same side.

[0028] Therefore, in this embodiment, the easy-tear packaging box, by setting two easy-tear straps 33 on the two side panels 3, allows for easy use by first opening the two upper flaps 21 of the packaging box containing the product, and then tearing the two easy-tear straps 33 respectively. The packaging box portion above the two easy-tear straps 33 can then be separated from the packaging box portion below, thus turning the packaging box into a semi-tray structure, which makes it easier to display the internal products. The easy-tear straps 33 also make opening the packaging box more convenient. After connecting the lower flap 11 to the two side flaps 32 on the same side, the two easy-tear straps 33 are exposed above the lower flap 11, which also ensures that tearing the easy-tear straps 33 will not damage the connection between the lower flap 11 and the side flaps 32 on the same side, resulting in a better formation of the semi-tray structure.

[0029] Specifically, the packaging box mentioned in this embodiment is the automatic box mentioned in the background art. It is made from pre-cut, unprocessed sheets of material and is automatically assembled using existing equipment during packaging. The plan view of this packaging box is shown below. Figure 1 As shown, the product is integrally cut from a flat cardboard sheet. This cardboard sheet can be coated cardboard, coated white cardboard, grey-backed white cardboard, or corrugated cardboard, or other materials can be used as needed. When automatically folded and formed by the corresponding equipment, the base plate 1 is placed on a flat surface of the equipment, the product is placed on the base plate 1, the two side plates 3 are folded upwards, and the top plate 2 is folded towards the tongue edge 31. The inner surface of the corresponding edge of the top plate 2 connects with the outer surface of the tongue edge 31. Each side flap 32 is folded inwards, the lower flap 11 is folded upwards, and the inner surfaces of both ends of the lower flap 11 connect with the outer surfaces of the side flap 32 on the same side. The upper flap 21 is folded downwards, and the inner surfaces of both ends of the upper flap 21 connect with the outer surfaces of the side flap 32 on the same side. At this time, the ends of the two easy-tear tapes 33 are exposed above the lower flap 11 and covered by the upper flap 21. The structure of the folded and assembled packaging box is as follows: Figure 2 As shown. When it is necessary to display the internal products, it can be done simply by tearing it open; it's easy and convenient.

[0030] In some embodiments, to facilitate the opening of the tear strip 33, refer to Figure 1 and Figure 3 Two notches 34 are provided at the end edge of the side cover 32 away from the side plate 3 and on both sides of the easy-tear strip 33. Two tear guide lines 35 are also provided on the side cover 32 and on both sides of the easy-tear strip 33. One end of the two tear guide lines 35 is connected to the two notches 34 respectively.

[0031] The other ends of the two tear guide lines 35 are spaced apart from the end edge of the side plate 3; optionally, the shape of the notch 34 can be according to... Figure 3The diagram shows a triangular notch, and a rounded chamfer can also be provided at the connection point between the triangular notch and the side flap 32. After the packaging box is formed, each tear guide line 35 is exposed on the lower flap 11 and can be covered by the upper flap 21. The tear guide lines 35 can indicate the opening position to the user and facilitate opening the easy-tear tape 33 by breaking the box body.

[0032] In some embodiments, in order to facilitate assembly by appropriate equipment, the bottom plate 1, top plate 2, and side plate 3 are all rectangular plates, and the two long edges of the bottom plate 1 are respectively connected to one of the long edges of the two side plates 3, one of the long edges of the top plate 2 is connected to the other long edge of one of the side plates 3, and the tongue edge 31 is connected to the other long edge of the other side plate 3; the two lower flaps 11 are connected to the two short edges of the bottom plate 1, the two upper flaps 21 are connected to the two short edges of the top plate 2, and the two side flaps 32 corresponding to each side plate 3 are connected to the two short edges of the side plate 3.

[0033] The rectangular plate has two long edges and two short edges. The two long edges form the opposite two side edges of the plate, and the two short edges form the opposite two end edges. The top plate 2, bottom plate 1, and side plates 3 have the same length, the top plate 2 and bottom plate 1 have the same width, and the two side plates 3 have the same width. After the packaging box is formed, it has a rectangular shape. The aforementioned tongue 31 can be made of a rectangular plate, or it can be made according to... Figure 1 The image shows a trapezoidal plate, with its lower base connected to the corresponding side plate 3.

[0034] Generally, the length of the easy-tear tape 33 is parallel to the connection line between the base plate 1 and the side plate 3. This easy-tear tape 33 is long and strip-shaped. Figure 1 In the planar unfolded view shown, the tear strip 33 extends along the length of the side panel 3 to the corresponding two side flaps 32 and connects with the corresponding edges of the side flaps 32.

[0035] Optionally, the easy-tear tape 33 may be spaced at the same distance from the opposite edges of the base plate 1. When two easy-tear tapes 33 are torn apart, the sidewalls on both sides of the side flap 32 in the resulting semi-support structure will have the same height. Alternatively, the easy-tear tapes 33 may be spaced at different distances from the opposite edges of the base plate 1. When two easy-tear tapes 33 are torn apart, the sidewalls on both sides of the side flap 32 in the resulting semi-support structure will have different heights, forming a stepped shape. The specific spacing size will depend on the actual requirements.

[0036] Furthermore, the upper flap 21, the lower flap 11, and the side flap 32 are all rectangular covers.

[0037] Optionally, the side flap 32 may have beveled or rounded corners at the two corners away from the side plate 3.

[0038] Generally, the top plate 2 and the bottom plate 1 have the same length and width. The two upper flaps 21 and the two lower flaps 11 have the same length, and the side flaps 32 have the same length. The widths of the upper flaps 21, the lower flaps 11, and the side flaps 32 are all the same. Furthermore, the sum of the widths of the two side flaps 32 located on the same side is less than the width of the bottom plate 1, and the sum of the widths of the upper flaps 21 and the lower flaps 11 located on the same side is equal to the width of the side plate 3. Thus, after the packaging box is formed, the two side flaps 32 located on the same side do not close together, while the upper flaps 21 and the lower flaps 11 located on the same side close together.

[0039] When the packaging box is formed by folding a flat panel, the two side panels 3 are folded 90° upwards toward the bottom panel 1, the top panel 2 is folded 90° toward the side near the tongue 31, the side flaps 32 are folded inwards 90° (that is, folded toward the area between the two side panels 3), the lower flap 11 is folded upwards 90°, and the upper flap 21 is folded downwards 90°. The bottom panel 1, the top panel 2, the two side panels 3 and the flaps are enclosed to form a rectangular box for storing products.

[0040] Optionally, in order to facilitate the folding and forming of the bundled packaging structure and improve folding efficiency, indentation lines 4 are provided at the folding positions between the two side plates 3 and the bottom plate 1, the folding positions between the top plate 2 and the corresponding side plates 3, the folding positions between the tongue 31 and the corresponding side plates 3, the folding positions between each side flap 32 and the corresponding side plates 3, the folding positions between each upper flap 21 and the top plate 2, and the folding positions between each lower flap 11 and the bottom plate 1.

[0041] Optionally, to facilitate the connection between the top plate 2 and the tongue 31, as well as the connection between the upper flap 21 and the lower flap 11 and each side flap 32, the outer surface of the tongue 31 is bonded and fixed to the inner surface of the other opposite edge of the top plate 2, and the inner surfaces of the upper flap 21 and the lower flap 11 are bonded and fixed to the outer surfaces of the two side flaps 32 on the same side, for example, by adhesive.

[0042] It is understood that the inner surface of the components mentioned in this article refers to the side facing the inside of the packaging box after the packaging box is formed, and the outer surface refers to the side facing the outside of the packaging box. The inner surface of each component is one of the same sides in the unfolded diagram of the packaging box, and the outer surface is another opposite side in the unfolded diagram.

[0043] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
