[0045] Please refer to Figures 1 to 5 , an embodiment of the present utility model provides a packaging box 100. The packaging box 100 includes a box body 85 and a handle assembly. The box body 85 is provided with an opening 12 and a receiving space 17. The handle assembly is disposed at the opening 12 and is used to cover or open the receiving space 17. The handle assembly includes a first cover plate 21, a second cover plate 32 and a third cover plate 43. The first cover plate 21 is provided with a handle hole 28. The first cover plate 21 is connected to the box body 100 through the third cover plate 43. When the handle assembly covers the opening 12 and the handle assembly is in a storage state (such as Figure 5 ), the third cover plate 43, the second cover plate 32 and the first cover plate 21 are stacked on the opening 12 in sequence. When the handle assembly covers the opening 12 and the handle assembly is in a carrying state (such as Figure 3 ), the third cover plate 43 and the second cover plate 32 are stacked on the opening 12 in sequence, and the first cover plate 21 is in a state of unfolding upward from the third cover plate 43.

[0046] In the above-mentioned packaging box, the handle assembly 100 includes a first cover plate 21, a second cover plate 32 and a third cover plate 43. The first cover plate 21 is provided with a handle hole 28. Thus, the packaging box 100 can be lifted by the user without setting an additional plastic handle, thereby reducing the consumption of plastic parts and meeting the requirements of environmental protection.

[0047] Specifically, the box body 85 is provided with an opening 12 and a receiving space 17. The opening 12 communicates with the receiving space 17. The handle assembly is arranged at the opening 12 and is used to cover or open the receiving space 17. Optionally, the packaging box 100 can be used to accommodate a solar panel, and the solar panel can be placed in the receiving space 17 through the opening 12. When the handle assembly opens the receiving space 17 (as shown in Figure 1 ), the user can directly put the solar panel into the receiving space 17 through the opening 12. When an item is placed in the receiving space 17 and the handle assembly can cover the opening 12 and the handle assembly is in the storage state (as shown in Figure 5 ), that is, the third cover plate 43, the second cover plate 32 and the first cover plate 21 are stacked on the opening 12 in sequence, so that the opening 12 is covered, and the sealing of the receiving space 17 can be realized. Thereby, it can avoid the solar panel being exposed to the external environment, and to a certain extent, it can prevent impurities such as water or dust in the outside world from damaging the solar panel, and improve the protection effect of the packaging box 100 on the solar panel. It can be understood that the packaging box is not limited to accommodating solar panels, and can also accommodate other items, and the present utility model does not limit this.

[0048] In the related art, an additional plastic handle is usually provided on the packaging box to facilitate the user to carry the product (such as a solar panel product). The plastic handle is difficult to degrade, resulting in the accumulation of plastic waste and causing harm to the environment. However, many solar panel products are relatively heavy, and removing the plastic handle may affect the user experience.

[0049] In the embodiment of the present utility model, when the handle assembly covers the opening 12 and the handle assembly is in the carrying state (as shown in Figure 3 ), that is, the third cover plate 43 and the second cover plate 32 are stacked on the opening 12 in sequence, so that the opening 12 is covered, and the first cover plate 21 is in a state of being unfolded upward from the third cover plate 43. A handle hole 28 is provided on the first cover plate 21, and the user can directly lift the packaging box 100 through the handle hole 28.

[0050] In some embodiments, the third cover plate 43 includes a first plate 46 and a second plate 48. The first cover plate 21 is connected to the box body 85 through the second plate 48 and the first plate 46 in sequence. A first crease 74 is provided at the connection formed by the connection of the first plate 46 and the second plate 48, and a second crease 78 is provided at the connection formed by the connection of the first cover plate 21 and the second plate 48.

[0051] In this way, the first cover plate 21 and the third cover plate 43 can be folded to cover the opening 12 through the first crease 74 and the second crease 78, which can not only protect the product in the packaging box 100 from the intrusion of dust and other pollutants, but also increase the buffering property at the top of the product, and play a good top protection role to a certain extent.

[0052] Specifically, in one embodiment, the packaging box 100 can be formed by folding a cardboard. Figure 6 is the flat die-cutting drawing of the packaging box 100, showing how to cut and fold the final packaging box 100 from the flat cardboard. In Figure 6 , the cutting lines help determine the cutting positions of the cardboard, representing the cutting boundaries of the outer contour and the internal structure of the packaging box 100, and the folding lines are used to help determine the folding positions of the cardboard. The creases are usually pre-imprinted on the cardboard through an indentation process so that users can easily fold along these creases to form the box body 85 and the handle assembly. Please refer to Figure 1 and Figure 2 . The first cover plate 21 is sequentially connected to the box body 85 through the second plate 48 and the first plate 46. When the first plate 46 moves along the connection formed by connecting with the box body 85 towards the opening 12 and covers the opening 12, the second plate 48 moves along the first crease 74 towards the first plate 46 and covers the first plate 46. The first plate 46 and the second plate 48 together form a two-layer stacked structure. The first cover plate 21 is in an upward-expanded state on the third cover plate 43 along the second crease 78. Then, the second cover plate 32 can be stacked on the third cover plate 43, and finally the first cover plate 21 is stacked on the second cover plate 32, so that the storage state of the handle assembly can be formed. The third cover plate 43, the second cover plate 32, and the first cover plate 21 are sequentially stacked on the opening 12. The two-layer stacked structure formed by the first plate 46 and the second plate 48 can not only protect the products in the packaging box 100 from the intrusion of dust and other pollutants, but also increase the buffering property at the top of the products, playing a good role in top protection to a certain extent.

[0053] When the packaging box 100 is in the Figure 5 storage state, the second cover plate 32 has covered the third cover plate 43, and the first cover plate 21 moves along the second crease 78 towards the second cover plate 32 and covers the second cover plate 43, so that the first cover plate 21, the second cover plate 32, and the third cover plate 43 together form a five-layer stacked structure, further enhancing the buffering property at the top.

[0054] In some embodiments, the handle hole 28 is a through hole opened along the thickness direction of the first cover plate 21.

[0055] In this way, the through hole can facilitate users to insert their fingers, making it more comfortable when lifting the product. At the same time, it can improve the lifting strength of the handle hole 28 to a certain extent, thereby ensuring that the packaging box 100 can be effectively carried or transported.

[0056] Specifically, in Figure 3In [the above context], the left - right direction is along the thickness direction of the first cover plate 21. A through - hole is provided as a handle hole 28 along the thickness direction of the first cover plate 21, enabling the user to insert their fingers into the through - hole, facilitating grasping, and allowing the entire packaging box 100 to be easily lifted and carried. The size of the through - hole should be such that the user's fingers can be comfortably inserted while maintaining the overall structural strength of the packaging box 100. Optionally, the edges of the through - hole are smoothed to avoid scratches or discomfort that may be caused by sharp edges, ensuring the safety and comfort of the user during use.

[0057] In some embodiments, the width range of the handle hole 28 is from 5 cm to 12 cm.

[0058] In this way, the lifting strength of the handle hole 28 can be guaranteed to a certain extent, while facilitating the user to insert their fingers and making it more comfortable to lift the product.

[0059] Specifically, the width of the handle hole 28 is most suitable for the width of more than four fingers of an adult. If the packaging box 100 is small, the opening should not be too large, otherwise the remaining area is too small, easily causing the handle hole 28 to deform and be damaged, and a width suitable for two to three fingers of an adult is more appropriate. If the width of the handle hole 28 is too small, when the user needs to lift the packaging box 100, it is difficult for the fingers to reach into the handle hole 28, which is not conducive to the user carrying or transporting the packaging box 100. If the width of the handle hole 28 is too large, the handle hole 28 occupies a large area of the handle assembly, resulting in less solid structure and reducing the lifting strength of the handle hole 28. When the user holds the handle hole 28 to lift the packaging box 100, the handle hole 28 is prone to breakage, causing the packaging box 100 to be unable to be effectively carried or transported. In practical applications, it is necessary to select a suitable width range of the handle hole 28 according to specific requirements and conditions to facilitate the user to lift the packaging box 28 without reducing the lifting strength.

[0060] In the embodiments of the present utility model, the width range of the handle hole 28 is from 5 cm to 12 cm. Therefore, it is convenient for the user to insert their fingers into the handle hole 28, making it more comfortable for the user to lift the product and reducing hand fatigue to a certain extent. At the same time, it can prevent the handle hole 28 from occupying a large area of the handle assembly, enhancing the lifting strength of the handle hole 28 to a certain extent, and thus ensuring that the packaging box 100 can be effectively carried or transported.

[0061] The width range of the handle hole 28 is D, where D is greater than or equal to 5 cm and less than or equal to 12 cm, that is, 5 cm ≤ D ≤ 12 cm. In some examples, D = 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, 12 cm or other values greater than or equal to 5 cm and less than or equal to 12 cm.

[0062] In some embodiments, the shape of the handle hole 28 includes regular shapes and / or irregular shapes.

[0063] Thus, different grasping manners can be flexibly provided to offer a comfortable grasping experience.

[0064] Specifically, the shape of the handle hole 28 can be selected as other different shapes according to user requirements or usage scenarios. Please refer to Figure 8 , the regular shapes include but are not limited to fan shapes, oval shapes, circular shapes, polygons, or any combination of a part and another part of at least two of the above shapes, etc. In one example, the shape of the handle hole 28 can also be a fan shape, and the fan shape also includes an annular fan shape. In one example, the shape of the handle hole 28 is an oval shape, and the oval shape can include a semi-oval shape. In actual situations, the shape of the handle hole 28 needs to be changed to better conform to the handle position of the product itself. The irregular shape is a shape other than the above regular shapes.

[0065] In Figure 1 , the handle assembly includes two first cover plates 21, and the shapes of the two handle holes 28 respectively arranged on the two first cover plates 21 are the same. In other embodiments, the shapes of the two handle holes 28 can be different. Thus, different grasping manners can be flexibly provided to offer a comfortable grasping experience, and at the same time, the aesthetics of the packaging box 100 can be increased to a certain extent.

[0066] The shape of the handle hole 28 can be specifically defined according to the actual situation, and the present utility model does not make specific limitations thereon.

[0067] In some embodiments, the handle hole 28 is arranged on the part of the first cover plate 21 away from the third cover plate 43.

[0068] Thus, to a certain extent, it is more labor-saving for the user to lift and carry the product, and it can ensure that the user can maintain balance and comfort when lifting the packaging box 100.

[0069] Specifically, the handle hole 28 is arranged on the part of the first cover plate 21 facing away from the third cover plate 43. Please refer to Figure 3, that is, the handle hole 28 is provided in the upper region of the first cover plate 21. The position of the handle hole 28 in the upper region enables the user not to bend over excessively or stretch the arm when lifting, which to a certain extent makes it easier for the user to lift and carry the product. Moreover, the thenar of the hand can jointly clamp the cover plate part between the upper edge of the handle hole 28 and the upper edge of the first cover plate 21 with the four fingers except the thumb, so that the first cover plate 21 can be held more stably. At the same time, the user's hands are respectively located in the upper regions on both sides of the first cover plate 21, and the weight can be more evenly distributed, reducing the tilt or shake caused by uneven weight, which helps the user better control the direction and stability of the packaging box 100 during the handling process. If the position of the handle hole 28 is too low, the user may lose control of the packaging box 100 when lifting, resulting in the product slipping or being damaged.

[0070] In some embodiments, the handle assembly includes two first cover plates 21, two second cover plates 32 and two third cover plates 43. The two second cover plates 32 are arranged on two opposite sides of the opening 12 along the first direction, and the two third cover plates 43 are arranged on two opposite sides of the opening 12 along the second direction. Each first cover plate 21 is connected to a corresponding third cover plate 43, and the first direction is perpendicular to the second direction.

[0071] In this way, the two first cover plates 21 and the two connected third cover plates 43 form an upward handle after folding, and are fixed by the acting force generated by the double-layer pressing of the two second cover plates 32. The packaging box 100 can be lifted by virtue of the tensile strength of the material used to make the packaging box 100.

[0072] Specifically, please refer to Figures 1 to 5 , the first direction is the front-back direction, the second direction is the left-right direction, and the first direction is perpendicular to the second direction. The two second cover plates 32 are arranged on two opposite sides of the opening 12 along the first direction. One of the second cover plates 32 is arranged on the front side of the opening 12 and connected to the box body 85, and the other second cover plate 32 is arranged on the rear side of the opening 12 and connected to the box body 85. The two third cover plates 43 are respectively arranged on two opposite sides of the opening 12 along the second direction. One of the third cover plates 43 is arranged on the left side of the opening 12 and connected to the box body 85, and the other third cover plate 43 is arranged on the right side of the opening 12 and connected to the box body 85. Each first cover plate 21 is connected to a corresponding third cover plate 43, so the two first cover plates 21 are arranged on two opposite sides of the opening 12 along the second direction.

[0073] The folding process of the handle assembly of the packaging box 100 is as shown in Figures 1 to 3As shown, the third cover plate 43 on the right first moves leftward along the connection with the box body 85, so that the first plate 46 and the second plate 48 cover the opening 12 by folding along the first crease 74. The third cover plate 43 on the left moves rightward along the connection with the box body 85, so that the first plate 46 and the second plate 48 cover the opening 12 by folding along the first crease 74. Then the second cover plate 32 at the rear moves forward along the connection with the box body 85 and covers the two second plates 48 of the two third cover plates 43. The second cover plate 32 at the front moves backward along the connection with the box body 85 and covers the second cover plate 32 at the rear, so that the opening 12 is covered. In Figure 3 In the handling state shown, the two second cover plates 32 and the third cover plate 43 can jointly form a four-layer laminated structure. The first cover plate 21 is fixed by the acting force generated by the double-layer pressing of the two second cover plates 32, which can improve the lifting strength of the handle hole 28.

[0074] Please combine Figure 4 and Figure 5 , the first cover plate 21 on the left first moves rightward along the second crease 78, and the first cover plate 21 on the right moves leftward along the second crease 78, so that the two first cover plates 21 cover the second cover plate 32. In Figure 5 In the storage state shown, on the left side of the box body 85, one first cover plate 21, two second cover plates 32, one first plate 46 and one second plate 48 can jointly form a five-layer laminated structure. On the right side of the box body 85, one first cover plate 21, two second cover plates 32, one first plate 46 and one second plate 48 can jointly form a five-layer laminated structure, which can ensure the sealing effect of the handle assembly on the accommodating space 17 to a certain extent.

[0075] Optionally, in the storage state, there is a certain distance between the two first cover plates 21, exposing the second cover plate 32. The second cover plate 32 can be tied to the box body 85 with sealing tape, so as to prevent the second cover plate 32 from separating from the box body 85 and causing the box body 85 to fall when the handle assembly is in the handling state during the handling of the packaging box 100.

[0076] Optionally, the packaging box 100 is made of corrugated paper. Corrugated paper generally consists of at least three layers of cardboard, including two smooth face papers (outer layers) and at least one middle wavy paper (corrugated paper core). Corrugated paper has high strength and stiffness. The packaging box 100 made of corrugated paper can provide good protection and support for the product. In the embodiment of the present utility model, the box body 12 and the handle assembly can both be made of corrugated paper. In the case where the handle assembly covers the opening 12 and the handle assembly is in the handling state (such as Figure 3As shown in the figure, that is, two third cover plates 43 and two second cover plates 32 are stacked on the opening 12 in sequence, the opening 12 is covered, and the first cover plate 21 is in a state of unfolding upward from the third cover plate 43. The two first cover plates 21 and the two connected third cover plates 43 are fixed by the upward handle generated after folding and the acting force generated by the double-layer capping of the two second cover plates 32. A handle hole 28 is provided on the first cover plate 21, and the user can directly lift the packaging box 100 through the handle hole 28 by means of the tensile strength of the corrugated paper through the handle hole 28.

[0077] In some embodiments, the packaging box 100 includes a buckle 54 and a slot 63. The slot 63 is provided on the second cover plate 32, and the buckle 54 is provided on the first cover plate 21. The buckle 54 is inserted into the slot 63 to make the handle assembly in a stored state.

[0078] In this way, the buckle 54 and the slot 63 cooperate with each other to hide and store the handle, which is beneficial to reducing the logistics transportation space and improving the user's unpacking experience to a certain extent.
