DETAILED DESCRIPTION
[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of the utility model.
[0026] As Figures 1-4 Shown in a kind of packing box that can be easily folded open and close, including bottom plate 1 and two side plates 4 and two end plates foldably connected in the four side edges of bottom plate 1, wherein, the foldably connected of the present embodiment is that adjacent two plates have crease, and two plates can be folded relatively under the structure action of crease. In the example, two side plates 4 are located at the two side edges of bottom plate 1 respectively, so that the left and right two sides of the box body shape structure are formed, and two end plates include first end plate 2 and second end plate 3, and are located at the two ends of bottom plate 1 respectively, so that the front and rear two end faces of the box body shape structure are formed.
[0027] Specifically, one end plate is foldably connected to a cover plate 5. In this example, the cover plate 5 is connected to the edge of the second end plate 3. The end of the cover plate 5 is foldably connected to a sealing plate 6. The sealing plate 6 has an adhesive area 13 on its surface, and a tear line 14 is formed between the adhesive area 13 and the sealing plate 6. More specifically, the adhesive area 13 is located in the middle of the sealing plate 6 near the outer edge, and has a triangular structure. In other embodiments, the adhesive area 13 can also be a rectangular structure. The surface of the adhesive area 13 is provided with adhesive. When the adhesive area 13 is not in use, release paper is attached to the adhesive to prevent adhesion and to facilitate peeling during use. When the user assembles the packaging box into a box-like structure, the adhesive area 13 can finally adhere to the surface of the first end plate 2, thereby sealing the packaging box. When the user needs to open the packaging box, pressing the adhesive area 13 firmly will tear the tear line 14 between the adhesive area 13 and the sealing plate 6, thus opening the box.
[0028] Another end plate has an outward-folding angle 7 formed at a position away from the base plate 1. A folding crease 8 is formed between the outward-folding angle 7 and the end plate. In this example, the outward-folding angle 7 is an isosceles right triangle, ensuring that when the outward-folding angle 7 folds outward, it aligns with the base plate 1, and that the side plates 4 on both sides also align with the base plate 1. The purpose of setting the outward-folding angle 7 is to... Figure 2 Under the condition shown in state D, after folding the third insert 11 and the fourth insert 12 inward, fold the cover 5 and the sealing plate 6 together towards the bottom plate 1 along the crease between the second end plate 3 and the cover 5, so that the packaging box can be stored (specifically as shown in state D). Figure 3 (As shown by the arrow indicating the folding direction), in its folded state, it can be wrapped in plastic film or multiple folded boxes can be stacked for easy transport to the user, reducing space usage. When shipped to the user, they only need to follow... Figure 3 Open the box in the opposite direction of the arrow shown, then open the first end panel 2 (which is in the folded state). At the same time, both side panels 4 open simultaneously, allowing for quick opening to the desired position. Figure 2 The structure of state D shown makes it convenient to quickly pack items that need to be packaged into boxes.
[0029] Specifically, insert plates can be folded and connected to both sides of the two end plates, both sides of the cover plate 5, and both sides of the sealing plate 6. In this example, the insert plates on both sides of the first end plate 2 are connected to the edge of the outward folding angle 7 and are rectangular in shape. The second insert plate 10 is connected to the edge of the second end plate 3 and is fan-shaped. The third insert plate 11 and the fourth insert plate 12 are trapezoidal in shape.
[0030] Specifically, each of the two side panels 4 includes an outer panel 401 that can be foldably connected to the bottom panel 1 and an inner snap-fit panel 402 that can be foldably connected to the outer panel 401. The inner snap-fit panel 402 can be folded toward the outer panel 401 and forms a cavity between it and the outer panel 401 that can accommodate the insert plate. Specifically, the cavity is mainly used to accommodate the first insert plate 9, the second insert plate 10 and the fourth insert plate 12, so as to make the packaging box structure stable and not easily deformed.
[0031] Specifically, slots 101 are provided on both sides of the base plate 1. The edges of the insert plates connected to the two end plates and the outer edge of the inner buckle plate 402 are provided with outward protruding strips 15. The strips 15 can be placed in the slots 101. When the first insert plate 9, the second insert plate 10 and the inner buckle plate 402 are folded toward the base plate 1, the strips 15 on them can be inserted into the slots 101, thereby playing a certain fixing effect and making the entire packaging box structure more stable.
[0032] Specifically, the outer plate 401 has slots 4011 at both ends that match the protrusions 15 (e.g., Figure 4 As shown), the insert plates connected to the two end plates can be quickly inserted into the cavity formed by the outer plate 401 and the inner snap plate 402 through the slot 4011, i.e. Figure 2 During the transition from state C to state D, when the second insert plate 10 is folded upwards to be inserted into the cavity of the outer plate 401 and the inner snap plate 402, the protrusion 15 on the second insert plate 10 can pass through the slot 4011 at the end of the outer plate 401 and enter between the outer plate 401 and the inner snap plate 402, thereby improving the assembly efficiency of the packaging box.
[0033] Specifically, the inner buckle plate 402 has a groove 4021 in the middle. This is designed so that when unfolding, a finger can be inserted into the groove 4021 to open the inner buckle plate 402.
[0034] like Figure 2 The diagram shows a flowchart of the packaging box from its unfolded state to its final box-shaped state. State A is the unfolded state. In this state, the first end plate 2, together with the first insert plates 9 on both sides, is folded upwards by 90° to form State B. Then, the outer plate 401 is folded upwards, and the inner snap plate 402 is folded upwards again, so that its end protrusion 15 is inserted into the slot 101, forming State C. Then, the second insert plate 10 is folded upwards by 90°, and the second end plate 3 is folded upwards, so that the second insert plate 10 is inserted into the cavity formed by the inner snap plate 402 and the outer plate 401, forming State D. Then, the third insert plate 11 is folded upwards by 90°, and the cover plate 5 is folded, forming State E. Finally, the fourth insert plate 12 is folded and inserted into the cavity formed by the inner snap plate 402 and the outer plate 401, forming the box-shaped structure in State F.
[0035] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
