Technical Field

[0001] This utility model relates to the field of packaging boxes, specifically a packaging box that is easy to stack. Background Technology

[0002] In the modern logistics and commodity circulation field, packaging boxes, as an indispensable carrier, bear the important mission of protecting, containing and transporting various goods. They are containers specially designed for holding, protecting and handling goods. Through reasonable structural design and material selection, they can effectively resist vibration, collision and squeezing during transportation, ensuring that goods arrive at their destination safely and without damage.

[0003] Due to its significant advantages such as low cost, ease of processing and shaping, light weight, and recyclability, paper packaging boxes have become the preferred packaging material for industries such as e-commerce, express delivery, food, daily chemicals, and electronics. In the e-commerce and express delivery industries, paper packaging boxes can be quickly customized in size to meet the packaging needs of different products, ensuring that the goods remain intact during long-distance transportation and multiple transfers. Existing paper packaging boxes are usually composed of a box body and several pieces of cardboard, which are assembled by production personnel to form a cube that can hold the items.

[0004] To achieve lightweight packaging, existing paper packaging boxes have relatively thin internal cardboard structures. When several boxes of the same size are stacked together, the bottom box cannot withstand the pressure applied from the top, resulting in poor stacking and storage capacity. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a packaging box that is easy to stack, so as to solve the technical problem that the paper packaging box has a low stacking and storage capacity due to the poor load-bearing capacity of the middle box structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stackable packaging box, including a box bottom, a box body being provided on the top of the box bottom, the box body including a support strip, a first box panel and a second box panel being connected to both sides of the support strip, a first bottom edge strip and a second bottom edge strip being fixedly installed on the top of the box bottom, a first reinforcing piece being provided at the corner of the box bottom, and a cover plate being movably installed on the top of the box body, with a second reinforcing piece installed at the corner of the cover plate.

[0007] By adopting the above technical solution, the first clip at the bottom of the first box panel is inserted into the first slot of the first bottom edge strip at the top of the packaging box. Then, the clip on one side of the second box panel is embedded into the groove on the inner wall of the first box panel, and the second box panel is pressed down into the second slot of the second bottom edge strip. Subsequently, another set of first and second box panels are installed in the same way as above, and finally the packaging box body is formed. The support strips of the internal structure of the packaging box body and the bottom of the packaging box form a more stable frame structure, which makes the top of the packaging box body more resistant to load.

[0008] The present invention is further configured such that a groove is provided on one side of the first box plate, and a locking block is installed on both sides of the second box plate.

[0009] By adopting the above technical solution, the card block on one side of the second box panel is embedded into the groove of the first box panel, and the first box panel and the second box panel are spliced ​​together. The two sets of first box panels and second box panels are spliced ​​together to form the box panels around the body of the packaging box.

[0010] The present invention is further configured such that a first retaining strip is installed on the top of the first box plate, and a first retaining groove is provided inside the first bottom edge strip.

[0011] By adopting the above technical solution, the first locking strip at the bottom of the first box panel is inserted into the first locking groove of the first bottom edge strip at the top of the packaging box. The first bottom edge strip limits and controls the first box panel through the first locking strip, so that the first box panel is stably installed on the top of the bottom of the packaging box.

[0012] The present invention is further configured such that a second locking strip is installed at the bottom of the second box plate, and a second locking groove is provided inside the second bottom edge strip.

[0013] By adopting the above technical solution, after the card block on one side of the second box panel is embedded in the groove on the inner wall of the first box panel, the second box panel is pressed down into the second slot of the second bottom edge strip, and the second bottom edge strip limits and fixes the second box panel through the second card strip.

[0014] The present invention is further configured such that the interior of the first box plate and the second box plate is provided with multiple sets of cavities, and the adjacent sets of cavities are arranged in a cross manner.

[0015] By adopting the above technical solution, the cavities inside the first and second box panels can buffer external collisions to a certain extent. Furthermore, the cavities allow the first and second box panels to have a smaller overall strength and a smaller mass, making it easier for personnel to handle the components of the packaging box.

[0016] The present invention is further configured such that a limiting piece is fixed to the top of the support bar, and the limiting piece is configured as an L-shape.

[0017] By adopting the above technical solution, when the packaging box is placed on top of a set of sealed packaging boxes, the bottom of the top packaging box is snapped into the top limiting piece of the packaging box, and the limiting piece of the bottom packaging box limits and fixes the top packaging box, so that the packaging box will not slide during transportation and storage.

[0018] The present invention is further configured such that a limiting frame is installed at the bottom of the cover plate, and the diameter of the limiting frame is smaller than the diameter of the inner wall of the packaging box.

[0019] By adopting the above technical solution, the plate covers the top of the packaging box body, the limiting frame at the bottom of the cover plate is embedded in the top of the packaging box body, and the outer wall of the limiting frame is in contact with the inner wall of the packaging box body. The limiting frame supports and expands the packaging box body composed of the two sets of first box plates and second box plates.

[0020] The present invention is further configured such that the support bar, the limiting piece, the first reinforcing piece and the second reinforcing piece are made of a relatively hard plastic material, and the combination of the limiting piece, the first reinforcing piece and the second reinforcing piece forms a frame structure with strong stability.

[0021] By adopting the above technical solution, the weight of the rectangular object on the top of the packaging box is transferred to the support strip through the second reinforcing plate at the corner of the cover plate. During the process of the packaging box supporting the top object, the packaging box mainly uses the limiting plate, the first reinforcing plate and the second reinforcing plate for gravity support, thereby reducing the phenomenon of overall deformation of the packaging box caused by excessive weight of the object on the top of the packaging box.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model sets up a packaging box bottom, support strip, first box panel, second box panel, first bottom edge strip, second bottom edge strip, and cover plate. The first locking strip at the bottom of the first box panel is inserted into the first locking groove of the first bottom edge strip at the top of the packaging box bottom.

[0035] Example 1

[0036] A type of packaging box that is easy to stack, such as Figure 1 - Figure 5 As shown, the packaging box includes a bottom 1, a box body on top of the bottom 1, a support strip 3, a first box panel 4 and a second box panel 403 connected to both sides of the support strip 3, a first bottom edge strip 2 and a second bottom edge strip 202 fixedly installed on the top of the bottom 1, first reinforcing pieces 302 at the corners of the bottom 1, and a cover plate 5 movably installed on the top of the box body. Second reinforcing pieces 501 are installed at the corners of the cover plate 5. The first retaining strip 402 at the bottom of the first box panel 4 is inserted into the first bottom edge strip 402 at the top of the bottom 1. The first slot 201 of the side strip 2 is inserted into the first slot 201, and then the card block 404 on one side of the second box plate 403 is inserted into the groove 401 on the inner wall of the first box plate 4. The second box plate 403 is pressed down into the second slot 203 of the second bottom side strip 202. Then, another set of first box plates 4 and second box plates 403 are installed in the same way as above, and finally the packaging box body is formed. The support strip 3 of the internal structure of the packaging box body and the bottom of the packaging box 1 form a more stable frame structure, which makes the top of the packaging box body more resilient.

[0037] Please see Figure 3 The first box panel 4 has a groove 401 on one side, and the second box panel 403 has a locking block 404 on both sides. The locking block 404 on one side of the second box panel 403 is embedded into the groove 401 of the first box panel 4. The first box panel 4 and the second box panel 403 are spliced ​​together, and the two sets of first box panels 4 and second box panels 403 are spliced ​​together to form the box panels around the body of the packaging box.

[0038] Please see Figure 2 and Figure 3 The top of the first box panel 4 is equipped with a first locking strip 402, and the inside of the first bottom edge strip 2 is provided with a first locking groove 201. The first locking strip 402 at the bottom of the first box panel 4 is inserted into the first locking groove 201 of the first bottom edge strip 2 at the top of the packaging box bottom 1. The first bottom edge strip 2 limits and controls the first box panel 4 through the first locking strip 402, so that the first box panel 4 is stably installed on the top of the packaging box bottom 1.

[0039] Please see Figure 2 and Figure 3 The bottom of the second box plate 403 is equipped with a second locking strip 405, and the interior of the second bottom edge strip 202 is provided with a second locking groove 203. When the locking block 404 on one side of the second box plate 403 is embedded into the groove 401 on the inner wall of the first box plate 4, the second box plate 403 is pressed down into the second locking groove 203 of the second bottom edge strip 202, and the second bottom edge strip 202 limits and fixes the second box plate 403 through the second locking strip 405.

[0040] Please see Figure 5The first box plate 4 and the second box plate 403 are provided with multiple sets of cavities 406. Two sets of adjacent cavities 406 are arranged in a cross pattern. The cavities 406 provided inside the first box plate 4 and the second box plate 403 can buffer external collisions to a certain extent. Furthermore, the arrangement of the cavities 406 allows the first box plate 4 and the second box plate 403 to have a smaller overall strength change and a smaller mass, which facilitates the handling of the components of the packaging box by personnel.

[0041] Please see Figure 2 The top of the support bar 3 is fixed with a limiting piece 301, and the limiting piece 301 is set in an L shape. When the packaging box is placed on top of a set of sealed packaging boxes, the bottom 1 of the top packaging box is snapped into the limiting piece 301 at the top of the packaging box.

The end of the clamping plate 6 is connected with the protrusion 601, and the protrusion 601 has a certain elastic deformation characteristic. When the cover plate 5 covers the top of the packaging box, the cover plate 5 presses the outer wall of the packaging box through the protrusion 601 at the end of the clamping plate 6, so that the cover plate 5 is more firmly installed on the top of the packaging box. In addition, multiple sets of pressing blocks 602 are provided on one side of the protrusion 601. The setting of the pressing block 602 increases the friction between the protrusion 601 and the packaging box, thereby reducing the possibility of the cover plate 5 slipping off the top of the packaging box.

[0046] The working principle of this utility model is as follows: First, place the bottom of the packaging box 1 on a horizontal surface. Then, insert the first locking strip 402 at the bottom of the first box panel 4 into the first locking groove 201 of the first bottom edge strip 2 at the top of the packaging box bottom 1. Next, insert the locking block 404 on one side of the second box panel 403 into the groove 401 on the inner wall of the first box panel 4, and press the second box panel 403 downward into the second locking groove 203 of the second bottom edge strip 202. Then, install another set of first box panels 4 and second box panels 403 in the same manner to finally form the packaging box body. After the two sets of first box panels 4 and second box panels 403 are installed and embedded on the top of the packaging box bottom 1, cover the top of the packaging box body with the cover plate 5. The limiting frame 502 at the bottom of the cover plate 5 is embedded in the packaging box. The top of the box is inside the box, and the outer wall of the limiting frame 502 contacts the inner wall of the box body. The limiting frame 502 supports and expands the box body composed of two sets of first box panels 4 and second box panels 403. In addition, the bottom of the support bar 3 is fixedly installed to the bottom of the box 1 through the first reinforcing plate 302, and the four corners of the cover plate 5 are equipped with second reinforcing plates 501 made of the same plastic hard plate material as the first reinforcing plate. When another set of boxes is placed on top of the sealed box, the bottom of the top box is snapped into the limiting plate 301 of the bottom box. The support bar 3 of the bottom box limits and controls the bottom of the top box through the limiting plate 301 to prevent the stacked boxes from sliding during transportation.
