[0001] Priority information

[0002] This application claims priority and benefits of patent application No. 202311138015.X filed with the State Intellectual Property Office of China on September 1, 2023, and the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the field of packaging technology, and more specifically, to a packaging box. Background Art

[0004] In recent years, with increasing awareness of environmental protection and resource conservation, industries such as new energy and green environmental protection have experienced rapid development. Against this backdrop, market requirements for product packaging have also become increasingly stringent. Typically, product packaging boxes require additional handles to facilitate user transportation of products (such as energy storage products). However, adding additional handles to packaging boxes increases production costs, thereby increasing resource consumption and failing to meet environmental protection requirements.

[0005] Summary of the Invention

[0006] An embodiment of the present application provides a packaging box.

[0007] The packaging box of the embodiment of the present application includes a box body and a handle assembly. The box body is provided with an opening and a storage space. The handle assembly is arranged at the opening and is used to cover or open the storage space. The handle assembly is provided with a handle hole, and the handle hole is used for a user to grasp and lift the packaging box. The handle assembly includes a first cover plate, a second cover plate, and a third cover plate. The first cover plate is provided with a first perforation, the second cover plate is provided with a second perforation, and the third cover plate is provided with a third perforation. When the handle assembly covers the opening, the first cover plate, the second cover plate, and the third cover plate are sequentially stacked on the opening, and the first perforation, the second perforation, and the third perforation are connected to form the handle hole.

[0008] In some embodiments, the handle assembly also includes a covering member, which is disposed in the second perforation. The covering member can move relative to the second cover plate to switch between a first state and a second state. In the first state, the covering member is used to cover the second perforation; in the second state, the covering member opens the second perforation; when the pressure applied to the covering member is greater than the binding force between the covering member and the second perforation, the covering member changes from the first state to the second state.

[0009] In some embodiments, at least a portion of the shielding member is connected to the second cover plate by a tear line. When the pressure applied to the shielding member is greater than the bonding force between the shielding member and the second cover plate, the tear line breaks to separate at least a portion of the shielding member from the second cover plate.

[0010] In some embodiments, the opening includes a first end, a second end, a third end, and a fourth end, the first end is opposite the third end, and the second end is opposite the fourth end. The second cover includes two, the first cover and the third cover are connected to the first end and the third end, respectively, and the two second cover are connected to the second end and the fourth end, respectively.

[0011] In some embodiments, the first through-hole, the second through-hole, and the third through-hole are each one. The second through-hole includes a first sub-hole and a second sub-hole, the first sub-hole being provided at a first side edge of the second cover plate connected to the second end, and the second sub-hole being provided at a second side edge of the second cover plate connected to the fourth end. When the handle assembly covers the opening, the first side edge and the second side edge are opposite, the first sub-hole and the second sub-hole together forming a single second through-hole, and the first through-hole, the second through-hole, and the third through-hole are correspondingly connected.

[0012] In certain embodiments, there are two each of the first, second, and third perforations. The two second cover panels each include a third side edge connected to the second end and a fourth side edge connected to the fourth end. One of the two second perforations extends from the third side edge toward the center of the opening, and the other extends from the fourth side edge toward the center of the opening. When the handle assembly covers the opening, the two first perforations, the two second perforations, and the two third perforations are connected to each other and together form two handle holes.

[0013] In certain embodiments, there are two each of the first perforation, the second perforation, and the third perforation. The two second cover plates each include a third side edge connected to the second end and a fourth side edge connected to the fourth end. One of the two second perforations extends through the second cover plate connected to the second end and is spaced from the third side edge. The other of the two second perforations extends through the second cover plate connected to the fourth end and is spaced from the fourth side edge. When the handle assembly covers the opening, the two first perforations, the two second perforations, and the two third perforations are connected to each other and together form two handle holes.

[0014] In some embodiments, the cross-sectional shape of the handle hole is at least one of a square, a sector, a circle, and a polygon.

[0015] In certain embodiments, the maximum dimension of the cross-sectional shape of the handle hole is [5 cm, 12 cm].

[0016] In some embodiments, the first through-hole, the second through-hole, and the third through-hole are all made by die cutting. The cross-sectional shapes of the first through-hole, the second through-hole, and the third through-hole are all the same.

[0017] In some embodiments, the first through-hole, the second through-hole, and the third through-hole are all formed by die cutting. At least two of the first through-hole, the second through-hole, and the third through-hole have different cross-sectional shapes.

[0018] In the packaging box of the present application, the handle assembly includes a first cover plate, a second cover plate and a third cover plate. The first cover plate is provided with a first perforation, the second cover plate is provided with a second perforation, and the third cover plate is provided with a third perforation. When the handle assembly covers the opening, the first cover plate, the second cover plate and the third cover plate are stacked on the opening in sequence, and the first perforation, the second perforation and the third perforation are connected to form a handle hole. Therefore, the packaging box can be lifted by the user without setting additional structural parts, thereby reducing the production cost of the packaging box, reducing resource consumption, and meeting the needs of green environmental protection.

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. In an example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0032] Referring to Figures 1 and 2, or Figures 3 and 4, or Figures 6 and 7, a packaging box 100 according to an embodiment of the present application includes a box body 10 and a handle assembly 20. The box body 10 has an opening 11 and a storage space 13. The handle assembly 20 is disposed at the opening 11 and is used to cover or open the storage space 13. The handle assembly 20 has a handle hole 210 for a user to grasp and lift the packaging box 100. The handle assembly 20 includes a first cover plate 21, a second cover plate 23, and a third cover plate 25. The first cover plate 21 has a first through-hole 211, the second cover plate 23 has a second through-hole 231, and the third cover plate 25 has a third through-hole 251. When the handle assembly 20 covers the opening 11, the first cover plate 21, the second cover plate 23, and the third cover plate 25 are sequentially stacked on the opening 11, and the first through-hole 211, the second through-hole 231, and the third through-hole 251 are connected to form the handle hole 210.

[0033] In some embodiments, the packaging box 100 can be manufactured using an integrated molding process, that is, the box body 10 and the handle assembly 20 are integrally molded, and the handle assembly 20 can move relative to the box body 10 to cover or open the storage space 13. The integrated molding configuration can enhance the connection strength between the box body 10 and the handle assembly 20, preventing breakage between the box body 10 and the handle assembly 20 when the user pulls the packaging box 100 through the handle hole 210. Of course, in other embodiments, the box body 10 and the handle assembly 20 can also be connected using a connection method such as bonding, that is, the box body 10 and the handle assembly 20 are two different structures. After the box body 10 and the handle assembly 20 are combined together using a connection method such as bonding, the handle assembly 20 can move relative to the box body 10 to cover or open the storage space 13.

[0034] Specifically, in some embodiments, the opening 11 is connected to the storage space 13. When the handle assembly 20 opens the storage space 13, the user can directly place the product (such as an energy storage power supply, a photovoltaic module, or an inverter) into the storage space 13 through the opening 11, or the product can be placed into the storage space 13 through the opening 11 by a conveying device (such as a robot or a transport device). When the product is placed in the storage space 13, the handle assembly 20 can cover the storage space 13, that is, the handle assembly 20 covers the opening 11 to achieve a seal of the storage space 13, thereby preventing the product from being exposed to the external environment, that is, preventing external impurities such as water or dust from contacting the product or even entering the interior of the product. Therefore, on the one hand, the cleanliness of the product can be ensured, and on the other hand, external impurities such as water or dust can be prevented from damaging the product, thereby improving the protective effect of the packaging box 100 on the product. In addition, when the handle assembly 20 covers the opening 11, the first through-hole 211, the second through-hole 231, and the third through-hole 251 can be connected to form a handle hole 210. In this case, the user can directly lift the packaging box 100 through the handle hole 210 to carry the product. Of course, a device such as a robot can also lift the packaging box 100 through the handle hole 210 to carry the product. In the embodiments of the present application, the user grasps the handle hole 210 to lift the packaging box 100 as an example.

[0035] It should be noted that, in some embodiments, the cross-sectional shape of the accommodating space 13 may be a regular shape such as a circle, square, triangle, or diamond, or other irregular shape. In the present application, the cross-sectional shape of the accommodating space 13 is a square. The shape and size of the opening 11 are the same as the cross-sectional shape and size of the accommodating space 13. For example, if the cross-sectional shape of the accommodating space 13 is a square, the shape of the opening 11 is also a square.

[0036] In some embodiments, the cross-sectional shape of the accommodating space 13 can be substantially the same as the cross-sectional shape of the product, that is, the cross-sectional shape of the product is also square, thereby facilitating the product to be placed into the accommodating space 13 through the opening 11. Specifically, in some embodiments, the cross-sectional dimension of the accommodating space 13 is greater than or equal to the cross-sectional dimension of the product. Thus, compared to a case where the cross-sectional dimension of the accommodating space 13 is smaller than the cross-sectional dimension of the product, the provision of the accommodating space 13 in this embodiment can, on the one hand, prevent the product from getting stuck with the peripheral wall 15 of the box body 10 when being placed into the accommodating space 13 through the opening 11, thereby improving the packaging efficiency of the product; on the other hand, when the product is placed in the accommodating space 13, the peripheral wall 15 of the box body 10 can restrain the product, preventing the product from shaking in the accommodating space 13 during the handling or transportation of the packaging box 100 and causing damage, thereby improving the transportation safety of the product. It is understood that in some embodiments, if the cross-sectional dimension of the accommodating space 13 is much larger than the cross-sectional dimension of the product, the product is likely to shake in the accommodating space 13 during the transportation or transportation of the packaging box 100, thereby causing damage to the product. Therefore, in this case, the packaging box 100 may also include a protective member (not shown), which is arranged between the product and the peripheral wall 15 of the box body 10, so as to fix the product and prevent the product from shaking in the accommodating space 13, thereby ensuring the safety of product transportation.

[0037] In the packaging box 100 of the present application, the handle assembly 20 includes a first cover plate 21, a second cover plate 23 and a third cover plate 25. The first cover plate 21 is provided with a first perforation 211, the second cover plate 23 is provided with a second perforation 231, and the third cover plate 25 is provided with a third perforation 251. When the handle assembly 20 covers the opening 11, the first cover plate 21, the second cover plate 23 and the third cover plate 25 are stacked on the opening 11 in sequence, and the first perforation 211, the second perforation 231 and the third perforation 251 are connected to form a handle hole 210. Therefore, the packaging box 100 can be lifted by the user without setting additional structural parts, thereby reducing the production cost of the packaging box 100, reducing resource consumption, and meeting the requirements of green environmental protection.

[0038] In addition, when the handle assembly 20 covers the opening 11, the first cover plate 21, the second cover plate 23 and the third cover plate 25 are stacked on the opening 11 in sequence, wherein the first cover plate 21 is opposite to the opening 11, and the first perforation 211, the second perforation 231 and the third perforation 251 are connected to form a handle hole 210. Therefore, compared with the case where the handle assembly 20 only includes one layer of cover plate, for example, the handle assembly 20 only includes the first cover plate 21, when the handle assembly 20 covers the opening 11, the first perforation 211 forms the handle hole 210. The tensile strength of the handle hole 210 in this embodiment is higher, thereby preventing the handle assembly 20 from breaking when the packaging box 100 is lifted through the handle hole 210, thereby improving the stability of product handling or transportation.

[0039] The packaging box 100 is further explained below with reference to the accompanying drawings.

[0040] Please refer to Figure 1, Figure 3 or Figure 6. In some embodiments, the packaging box 100 is made of corrugated paper. Among them, corrugated paper is a material made of cardboard. Generally, corrugated paper is composed of three layers of cardboard, the corrugated layer in the middle is the corrugated core, and the flat layers on both sides are facial tissue. Corrugated paper has the characteristics of high strength, rigidity and recyclability. Therefore, the packaging box 100 made of corrugated paper can provide good protection and support for the product. Specifically, in some embodiments, the box body 10 and the handle assembly 20 can both be made of corrugated paper. Therefore, when the packaging box 100 is damaged and cannot be used, the packaging box 100 made of corrugated paper can be recycled and reused. Compared with the packaging box 100 made of non-recyclable materials such as plastic, the packaging box 100 in this embodiment not only does not cause harm to the environment, but also can reduce resource waste, meeting the needs of green environmental protection.

[0041] Please refer to Figures 1 and 2, or Figures 3 and 4, or Figures 6 and 7. In some embodiments, the first perforation 211, the second perforation 231 and the third perforation 251 are all processed and made using a die cutter. Among them, a die cutter is a tool used for cutting, engraving or stamping materials. It is usually made of a solid metal, such as steel or aluminum. The die cutter can be designed into various shapes and sizes according to specific needs, and is used for cutting, engraving or stamping on the material to produce the desired shape and structure. Specifically, in some embodiments, the die cutter can process the first cover plate 21, the second cover plate 23 and the third cover plate 25 respectively to open the first perforation 211 on the first cover plate 21, the second perforation 231 on the second cover plate 23, and the third perforation 251 on the third cover plate 25. In other embodiments, when the handle assembly 20 covers the opening 11, the first cover plate 21, the second cover plate 23, and the third cover plate 25 are sequentially stacked on the opening 11. In this case, a die cutter can punch the handle assembly 20 once to form the first through-hole 211 on the first cover plate 21, the second through-hole 231 on the second cover plate 23, and the third through-hole 251 on the third cover plate 25.

[0042] In certain embodiments, the cross-sectional shape of the handle hole 210 is at least one of a square, a sector, a circle, and a polygon. Of course, the cross-sectional shape of the handle hole 210 can also be selected from other different shapes based on user needs or usage scenarios. For example, the cross-sectional shape of the handle hole 210 can also be a regular shape such as a star or a semicircle, or other irregular shapes. The cross-sectional shape of the handle hole 210 is the same as the shape of the cutting die. For example, if the cross-sectional shape of the handle hole 210 is square, the shape of the cutting die can also be square. The cross-sectional shape of the handle hole 210 can be selected based on the functional requirements and usage scenarios of the packaging box 100. For example, when the product in the storage space 13 is heavy, the handle hole 210 can be selected with a larger cross-sectional shape to increase the user's grip on the grip hole, thereby allowing the user to exert greater lifting force on the packaging box 100.

[0043] Please refer to Figures 1 and 2, or Figures 3 and 4, or Figures 6 and 7 again. In some embodiments, the cross-sectional shapes of the first through-hole 211, the second through-hole 231, and the third through-hole 251 are all the same. Therefore, when the handle assembly 20 covers the opening 11, the cross-sectional shapes of the first through-hole 211, the second through-hole 231, and the third through-hole 251 are the cross-sectional shapes of the handle hole 210. In this case, only one shape of cutting die is used to achieve the processing of the first through-hole 211, the second through-hole 231, and the third through-hole 251. For example, when the cross-sectional shapes of the first perforation 211, the second perforation 231 and the third perforation 251 are all circular, the shape of the cutting die is also circular. If the cross-sectional shapes of the first perforation 211, the second perforation 231 and the third perforation 251 are of the same size, only one cutting die is needed to process the first perforation 211, the second perforation 231 and the third perforation 251 without replacing the cutting die, thereby improving the processing efficiency of the packaging box 100 to a certain extent.

[0044] In other embodiments, the cross-sectional shapes of at least two of the first through-hole 211, the second through-hole 231, and the third through-hole 251 are different. Specifically, in some embodiments, the cross-sectional shapes of the first through-hole 211 and the second through-hole 231 are the same, but different from the cross-sectional shape of the third through-hole 251; or the cross-sectional shapes of the first through-hole 211 and the third through-hole 251 are the same, but different from the cross-sectional shape of the second through-hole 231; or the cross-sectional shapes of the second through-hole 231 and the third through-hole 251 are the same, but different from the cross-sectional shape of the first through-hole 211; or the cross-sectional shapes of the first through-hole 211, the second through-hole 231, and the third through-hole 251 are all different. In this embodiment, the cross-sectional shape of the handle hole 210 may be different from the shapes of the first through-hole 211, the second through-hole 231, and the third through-hole 251, or the cross-sectional shape of the handle hole 210 may be the same as the shape of at least one of the first through-hole 211, the second through-hole 231, and the third through-hole 251. For example, if the first through-hole 211 and the third through-hole 251 are both square and the second through-hole 231 is circular, the handle hole 210 can be circular. When processing the first through-hole 211, the second through-hole 231, and the third through-hole 251, the user needs to select a corresponding die shape based on the shapes of the first through-hole 211, the second through-hole 231, and the third through-hole 251.

[0045] In some embodiments, the maximum dimension of the cross-sectional shape of the handle hole 210 is [5 cm, 12 cm]. Specifically, in some embodiments, the maximum dimension of the cross-sectional shape of the handle hole 210 can be any one of 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, and 12 cm, or any value between any two of the values.

[0046] If the maximum dimension of the cross-sectional shape of the handle hole 210 is less than 5 cm, when the user needs to lift the packaging box 100, it is difficult for the user to insert his fingers into the handle hole 210, which is not conducive to the user's handling or transportation of the packaging box 100; if the maximum dimension of the cross-sectional shape of the handle hole 210 is greater than 12 cm, the handle hole 210 occupies a larger area of ​​the handle assembly 20. In other words, the handle assembly 20 has less physical structure, which will lead to a decrease in the tensile strength of the handle hole 210. When the user grasps the handle hole 210 to lift the packaging box 100, the handle hole 210 is easy to break, resulting in the packaging box 100 being unable to be effectively handled or transported. In the embodiment of the present application, the maximum dimension of the cross-sectional shape of the handle hole 210 is [5 cm, 12 cm]. This, on the one hand, prevents the user's fingers from having difficulty inserting into the handle hole 210, ensuring that the user can normally carry the packaging box 100; on the other hand, it prevents the handle hole 210 from occupying a large area of ​​the handle assembly 20, thereby improving the tensile strength of the handle hole 210, and further ensuring that the packaging box 100 can be effectively carried or transported. It should be noted that in some embodiments, the maximum dimension of the cross-sectional shape of the handle hole 210 can be: the longest length of the cross-sectional shape of the handle hole 210. For example, when the cross-sectional shape of the handle hole 210 is circular, the maximum dimension of the cross-sectional shape of the handle hole 210 is the diameter of the circle.

[0047] Referring to Figures 1 and 2, or Figures 3 and 4, or Figures 6 and 7, in certain embodiments, the handle assembly 20 may further include a shielding member 27 disposed within the second through-hole 231. The shielding member 27 is movable relative to the second cover plate 23 to switch between a first state and a second state. In the first state, the shielding member 27 shields the second through-hole 231. In the second state, the shielding member 27 opens the second through-hole 231. When the pressure applied to the shielding member 27 exceeds the binding force between the shielding member 27 and the second through-hole 231, the shielding member 27 transitions from the first state to the second state.

[0048] It should be noted that, in some embodiments, the first state may be: the state of the shielding member 27 when the shielding member 27 is not subjected to pressure, or the pressure applied to the shielding member 27 is less than the binding force between the shielding member 27 and the second perforation 231; the second state may be: the state of the shielding member 27 when the pressure applied to the shielding member 27 is greater than the binding force between the shielding member 27 and the second perforation 231.

[0049] Specifically, the cross-sectional shape and size of the shielding member 27 are substantially identical to those of the second through-hole 231. In the first state, the shielding member 27 is able to block the second through-hole 231. That is, when the shielding member 27 is in the first state and the handle assembly 20 blocks the opening 11, the shielding member 27 completely blocks the second through-hole 231. In this case, the handle assembly 20 completely covers the opening 11, preventing dust and other impurities from the external environment from entering the accommodating space 13 and coming into contact with the product. This not only reduces the impact of the external environment on the product, but also ensures the cleanliness of the product. In the second state, the shielding member 27 can move relative to the second cover plate 23 to open the second through-hole 231. In this case, the shielding member 27 partially blocks the second through-hole 231, or the shielding member 27 does not block the second through-hole 231 at all. As a result, the first through-hole 211, the second through-hole 231, and the third through-hole 251 can be connected to form the handle hole 210, and the user can lift the packaging box 100 through the handle hole 210. It should be noted that, in some embodiments, the pressure applied to the shielding member 27 can be the pressure generated when the user presses the shielding member 27, or the pressure applied to the shielding member 27 can be the pressure generated when a device such as a robot presses the shielding member 27.

[0050] Furthermore, in some embodiments, at least a portion of the shielding member 27 is connected to the second cover plate 23 by a tear line 28. When the pressure applied to the shielding member 27 is greater than the bonding force between the shielding member 27 and the second cover plate 23, the tear line 28 breaks to separate at least a portion of the shielding member 27 from the second cover plate 23.

[0051] The tear line 28 is a special fiber material, also known as a tearable thread or easy-to-tear fabric, and has low tensile strength. In some embodiments, the entire shielding member 27 is connected to the second cover plate 23 using the tear line 28 and is located within the second perforation 231. Thus, in a first state, the shielding member 27 can block the second perforation 231. In a second state, i.e., when the pressure applied to the shielding member 27 exceeds the binding force between the shielding member 27 and the second cover plate 23, the tear line 28 can break, completely separating the shielding member 27 from the second cover plate 23. At this point, the shielding member 27 opens the second perforation 231. It is understood that when the shielding member 27 is completely separated from the second cover plate 23, it can fall into the accommodating space 13.

[0052] In other embodiments, a portion of the shielding member 27 is connected to the second cover plate 23 using an easy-tear line 28. Specifically, in some embodiments, the shielding member 27 includes a first peripheral edge 275 and a second peripheral edge 277 that are connected to each other, wherein the first peripheral edge 275 is connected to the second cover plate 23 using the easy-tear line 28, and the second peripheral edge 277 is connected to the second cover plate 23 using a connection method such as bonding, or the second peripheral edge 277 and the second cover plate 23 are integrally formed. As a result, the bonding force between the first peripheral edge 275 and the second cover plate 23 is less than the bonding force between the second peripheral edge 277 and the second cover plate 23. In the first state, the first peripheral edge 275 and the second peripheral edge 277 are both connected to the second cover plate 23, and the shielding member 27 can shield the second through-hole 231. In the second state, that is, when the pressure applied to the shielding member 27 is greater than the binding force between the shielding member 27 and the second cover plate 23, in other words, when the pressure applied to the shielding member 27 is greater than the binding force between the first peripheral edge 275 and the second cover plate 23, the fragile tear line 28 breaks, separating the first peripheral edge 275 of the shielding member 27 from the second cover plate 23. At this time, the shielding member 27 opens the second through-hole 231. In this case, the shielding member 27 will not fall off the handle assembly 20, thereby ensuring the integrity of the packaging box 100.

[0053] It can be understood that in some embodiments, when at least a portion of the shielding member 27 is separated from the second cover plate 23 to open the second perforation 231, the user can lift the packaging box 100 through the handle hole 210 to transport the product. After the transportation is completed, the user's hand leaves the handle hole 210. At this time, the shielding member 27 is not subjected to pressure, and the shielding member 27 can move relative to the second cover plate 23 to change from the second state to the first state to re-cover the second perforation 231, thereby reducing or even avoiding the adverse effects of the external environment on the product.

[0054] Referring to Figures 1 and 2, or Figures 3 and 4, or Figures 6 and 7, in certain embodiments, the opening 11 includes a first end 111, a second end 113, a third end 115, and a fourth end 117, wherein the first end 111 is opposite the third end 115, and the second end 113 is opposite the fourth end 117. The second cover plates 23 include two, the first cover plate 21 and the third cover plate 25 being connected to the first end 111 and the third end 115, respectively, and the two second cover plates 23 being connected to the second end 113 and the fourth end 117, respectively.

[0055] Specifically, in some embodiments, the first end 111, the second end 113, the third end 115, and the fourth end 117 are connected end to end to collectively enclose the opening 11 of the box body 10. When the handle assembly 20 covers the opening 11, the first cover plate 21 first moves relative to the box body 10 along the first end 111 and covers the opening 11. Then, the two second cover plates 23 move relative to the box body 10 along the second end 113 and the fourth end 117, respectively, and are stacked on the first cover plate 21. Finally, the third cover plate 25 moves relative to the box body 10 along the third end 115 and is stacked on the two second cover plates 23. Thus, the first cover plate 21, the two second cover plates 23, and the third cover plate 25 can collectively form a three-layer stacked structure, thereby ensuring the sealing effect of the handle assembly 20 on the accommodating space 13 while also improving the tensile strength of the handle hole 210.

[0056] It can be understood that, in some embodiments, when the first cover plate 21 is not provided with the first perforation 211, the first cover plate 21 may be substantially the same as the shape and size of the opening 11. In other words, when the handle assembly 20 covers the opening 11, the first cover plate 21 can cover the entire opening 11; when the third cover plate 25 is not provided with the third perforation 251, the third cover plate 25 may be substantially the same as the shape and size of the opening 11. In other words, when the handle assembly 20 covers the opening 11, the third cover plate 25 can cover the entire opening 11. On the one hand, this can ensure the covering effect of the handle assembly 20 on the opening 11 and prevent the product in the accommodating space 13 from contacting the external environment; on the other hand, when the handle assembly 20 covers the opening 11, the side edges of the first cover plate 21 and the third cover plate 25 can be roughly aligned, thereby facilitating the positioning of the first perforation 211 and the third perforation 251 during processing, thereby improving the processing efficiency of the packaging box 100.

[0057] Referring to Figures 1 and 2 , in some embodiments, the first through-hole 211, the second through-hole 231, and the third through-hole 251 are each one. The second through-hole 231 includes a first sub-hole 2311 and a second sub-hole 2313. The first sub-hole 2311 is located at a first side edge 233 of the second cover plate 23 connected to the second end 113, and the second sub-hole 2313 is located at a second side edge 235 of the second cover plate 23 connected to the fourth end 117. When the handle assembly 20 covers the opening 11, the first side edge 233 and the second side edge 235 are opposite each other. The first sub-hole 2311 and the second sub-hole 2313 together form a second through-hole 231, and the first through-hole 211, the second through-hole 231, and the third through-hole 251 are correspondingly connected. It should be noted that, in some embodiments, when the second through-hole 231 includes a first sub-hole 2311 and a second sub-hole 2313, the shielding member 27 includes a first sub-portion 271 and a second sub-portion 273, the first sub-portion 273 is arranged in the first sub-hole 2311 and is connected to the second cover plate 23, and the second sub-portion 273 is arranged in the second sub-hole 2313 and is connected to the second cover plate 23.

[0058] Specifically, in some embodiments, the second cover plate 23 connected to the second end 113 includes a first side edge 233, which is spaced apart from the second end 113, and the second cover plate 23 connected to the fourth end 117 includes a second side edge 235, which is spaced apart from the fourth end 117. The first sub-hole 2311 can be recessed from the first side edge 233 toward the second end 113, and the second sub-hole 2313 can be recessed from the second side edge 235 toward the fourth end 117. Thus, when the handle assembly 20 covers the opening 11, the first sub-hole 2311 and the second sub-hole 2313 together form a second through-hole 231, and the first through-hole 211, the second through-hole 231, and the third through-hole 251 are correspondingly connected to form the handle hole 210. In one example, when the handle assembly 20 covers the opening 11, the first side edge 233 is spaced apart from the second side edge 235. In this case, the first sub-hole 2311 and the second sub-hole 2313 are spaced apart and opposite to each other. The first sub-hole 2311, the second sub-hole 2313, and the gap between the two second cover plates 23 collectively form the second through-hole 231. In another example, when the handle assembly 20 covers the opening 11, the first side edge 233 and the second side edge 235 are connected. In this case, the first sub-hole 2311 and the second sub-hole 2313 are connected and collectively form the second through-hole 231.

[0059] It should be noted that, in some embodiments, when the first perforation 211, the second perforation 231, and the third perforation 251 each include one, the handle hole 210 is also one. Thus, when the user needs to lift the packaging box 100, the user can reach into the handle hole 210 with one hand and buckle the surface of the first cover plate 21 (the side of the first cover plate 21 facing the accommodating space 13) to achieve the lifting of the packaging box 100. In this case, since the user only uses one hand to apply force to the packaging box 100, the packaging box 100 in this embodiment is more suitable for packaging lighter products. Of course, it is understandable that due to the influence of factors such as the usage scenario of the packaging box 100 and the shape of the handle hole 210, the packaging box 100 in this embodiment can also be used to package heavier products.

[0060] In some embodiments, when the handle assembly 20 covers the opening 11, the centers of the first perforation 211, the second perforation 231, and the third perforation 251 may all coincide with the center of the opening 11. Thus, when the user lifts the packaging box 100 through the handle hole 210, the lifting force exerted by the user on the packaging box 100 is more uniform, preventing the packaging box 100 from tilting due to uneven force, thereby improving the stability of product handling.

[0061] Referring to Figures 3 and 4 , in some other embodiments, there are two first through-holes 211, two second through-holes 231, and two third through-holes 251. The two second cover plates each include a third side edge 237 connected to the second end 113 and a fourth side edge 239 connected to the fourth end 117. One of the two second through-holes 231 extends from the third side edge 237 toward the center of the opening 11, and the other extends from the fourth side edge 239 toward the center of the opening 11. When the handle assembly 20 covers the opening 11, the two first through-holes 211, the two second through-holes 231, and the two third through-holes 251 are connected to each other and together form two handle holes 210.

[0062] Specifically, referring to Figure 5, in some embodiments, the third side edge 237 is opposite to the first side edge 233, and the fourth side edge 239 is opposite to the second side edge 235. One of the two second through-holes 231 can extend from the third side edge 237 toward the first side edge 233, and the other of the two second through-holes 231 can extend from the fourth side edge 239 toward the second side edge 235. Therefore, when the handle assembly 20 covers the opening 11, the two second through-holes 231 are both located near the peripheral wall 15 of the box body 10. Correspondingly, the two first through-holes 211 and the two third through-holes 251 are also located near the peripheral wall 15 of the box body 10, and the two first through-holes 211, the two second through-holes 231, and the two third through-holes 251 are respectively connected to each other and together form two handle holes 210. Thus, when the user needs to lift the packaging box 100 through the handle holes 210, the user can extend both hands into the two handle holes 210 and hold the surface of the first cover plate 21 (the side of the first cover plate 21 facing the accommodating space 13) to lift the packaging box 100. That is, both hands of the user can apply a lifting force to the packaging box 100. Therefore, the packaging box 100 in this embodiment is more suitable for packaging heavier products. Of course, it is understandable that the packaging box 100 in this embodiment is also suitable for packaging lighter products.

[0063] Referring to Figures 6 and 7 , in yet other embodiments, there are two first through-holes 211, two second through-holes 231, and two third through-holes 251. One of the two second through-holes 231 extends through the second cover plate connected to the second end 113 and is spaced from the third side edge 237. The other of the two second through-holes 231 extends through the second cover plate connected to the fourth end 117 and is spaced from the fourth side edge 239. When the handle assembly 20 covers the opening 11, the two first through-holes 211, the two second through-holes 231, and the two third through-holes 251 are connected to each other and together form two handle holes 210.

[0064] Specifically, referring to Figure 5, in some embodiments, one of the two second through-holes 231 is located between the first side edge 233 and the third side edge 237, and the other of the two second through-holes 231 is located between the second side edge 235 and the fourth side edge 239. Therefore, when the handle assembly 20 covers the opening 11, the two second through-holes 231 are both located near the center of the opening 11. Correspondingly, the two first through-holes 211 and the two third through-holes 251 are also both located near the center of the opening 11, and the two first through-holes 211, the two second through-holes 231, and the two third through-holes 251 are respectively connected to each other and together form two handle holes 210. Therefore, when the user lifts the packaging box 100 through the handle holes 210, the user can reach into one handle hole 210 with one hand and reach out from the other handle hole 210 with one hand, that is, the user can apply lifting force to the packaging box 100 with one hand. Therefore, the packaging box 100 in this embodiment is more suitable for packaging lighter products.

[0065] In addition, when the user needs to lift the packaging box 100 through the handle hole 210, the user's hands can be inserted into the two handle holes 210 respectively, and hold the surface of the first cover plate 21 (the side of the first cover plate 21 facing the accommodating space 13) to lift the packaging box 100, that is, both hands of the user can apply lifting force to the packaging box 100. Therefore, the packaging box 100 in this embodiment is also suitable for packaging heavier products.

[0066] If the first cover plate 21 and the third cover plate 25 are not connected in any manner, at least one of the first cover plate 21, the second cover plate 23, and the third cover plate 25 may shake or flip during transportation, causing the handle assembly 20 to be unable to cover the opening 11. This may result in the external environment coming into contact with the product and adversely affecting the product. Therefore, referring to Figures 3, 4, and 8, in some embodiments, when the handle assembly 20 covers the opening 11, the first cover plate 21 and the third cover plate 25 may be connected by a plug-in connection. This prevents at least one of the first cover plate 21, the second cover plate 23, and the third cover plate 25 from shaking or flipping during transportation, causing the handle assembly 20 to be unable to cover the opening 11. This ensures the cleanliness of the product and prevents damage to the product from impurities such as water and dust, thereby improving the product protection provided by the packaging box 100. Furthermore, the plug-in connection between the first cover plate 21 and the third cover plate 25 facilitates the reuse of the packaging box 100, meeting environmental protection requirements.

[0067] Specifically, referring to FIG8 , in some embodiments, the first cover plate 21 is provided with a through first through slot 213, and the first through slot 213 is located near the first end 111 of the first cover plate 21. The handle assembly 20 further includes a first protrusion 29, which extends from the first end 111 in a direction away from the first end 111. The first protrusion 29 is movable relative to the box body 10, and the projection of the first protrusion 29 from the first end 111 to the third end 115 is completely located within the first through slot 213. The third cover plate 25 further includes a second protrusion 253, which extends from a side edge of the third cover plate 25 away from the third end 115 in a direction away from the third end 115. The second protrusion 253 is movable relative to the third cover plate 25, and the second protrusion 253 is provided with a through second through slot 2531.

[0068] When the handle assembly 20 covers the opening 11, the second protrusion 253 can pass through the first through-slot 213 and extend into the accommodating space 13. Then, the first protrusion 29 can pass through the second through-slot 2531 and extend into the accommodating space 13, thereby combining the first cover plate 21 and the third cover plate 25. Furthermore, when the handle assembly 20 needs to open the opening 11, the user can first pull the first protrusion 29 out of the second through-slot 2531, that is, separate the first protrusion 29 from the second through-slot 2531, and then pull the second protrusion 253 out of the first through-slot 213, that is, separate the second protrusion 253 from the first through-slot 213, thereby releasing the first cover plate 21 and the third cover plate 25.

[0069] It should be noted that, in some embodiments, the number of the first through groove 213 and the second through groove 2531 can be one or more, wherein the quantitative relationship between the first protrusion 29 and the second through groove 2531 can be one to one, or many to one, and the quantitative relationship between the second protrusion 253 and the first through groove 213 can be one to one, or many to one.
