Description

Technical Field

[0001] This application relates to the field of printing equipment packaging technology, and more particularly to a packaging box. Background Technology

[0002] The processing cartridge, a core component in imaging equipment (also known as a printer), is detachably installed within the device. It forms prints, such as text or images, on a printing medium (similar to paper). The quality of the processing cartridge significantly impacts the reliability of the imaging equipment; therefore, newly manufactured cartridges require proper packaging to minimize the likelihood of contamination, breakage, or other quality-affecting issues. However, existing packaging structures have deficiencies in protecting the processing cartridges, making them susceptible to structural problems such as plastic deformation, cracking, or breakage. Summary of the Invention

[0003] In view of this, this application provides a packaging box that can better protect the processing box, and the processing box is not prone to structural problems such as plastic deformation, cracking or breakage.

[0004] This application provides a packaging box for packaging a processing box, which can be detachably installed on an imaging device. The processing box includes a main body and a gripping part, with the gripping part offset to one side of the main body. The packaging box includes a first box body, a second box body, and a hinge. The first box body includes a first receiving groove for receiving at least a portion of the processing box. The first receiving groove is provided with an inlet, through which the processing box can be placed. The second box body includes a second receiving groove for receiving another portion of the processing box. The first box body is rotatably connected to the second box body via the hinge. The second box body can be located at least in a first position or a second position relative to the first box body. If the second box body is in the first position, the inlet is closed by the second box body. If the second box body is in the second position, the inlet is open. The inner wall of the first receiving groove includes a first protective part for protecting the gripping part. The first protective part is disposed in the inner wall of the first receiving groove near the hinge.

[0005] When a packaging box containing a processing box is subjected to impact loads from other packaging boxes located to the side, the hinge structure and the structures in the first box body furthest from the first protective part bear the impact load before the first protective part. In other words, the hinge structure and the structures in the first box body furthest from the first protective part provide good cushioning for the first protective part. Consequently, the gripping part protected by the first protective part is less prone to plastic deformation, cracking, or breakage. When opening or closing the packaging box, it is customary to keep the first box body relatively stationary while moving the second box body relative to the first box body. Therefore, the common practice for placing packaging boxes is to position the first box body below the second box body. Accordingly, the first protective part is a structure located in the lower half of the packaging box. This arrangement allows the structure of the upper second box body to provide good cushioning for the lower first protective part when the packaging box containing the processing box is subjected to impact loads from other packaging boxes located above and to the upper right, thus preventing plastic deformation, cracking, or breakage of the gripping part protected by the first protective part.

[0006] Optionally, the first housing includes a first leg that protrudes outward and in a direction away from the second housing, and a first protective portion is located between the first leg and the hinge portion.

[0007] Optionally, a set connection line is provided between the first support leg and the hinge part, and a set interval distance D1 is provided between the first protection part and the connection line, satisfying 3mm≤D1≤10mm.

[0008] Optionally, the inner wall of the first receiving groove also includes a second protective part, which is used to protect the main body part, and the first protective part is closer to the hinge part than the second protective part.

[0009] Optionally, the first protective part includes an intersecting first inner wall surface and a second inner wall surface, with a set obtuse angle α between the first inner wall surface and the second inner wall surface, satisfying 100°≤α≤160°.

[0010] Optionally, the processing cartridge includes a protective member for covering the developing component of the processing cartridge; the inner wall of the second receiving groove includes an inner protrusion structure that protrudes into the receiving space of the second receiving groove and is used to abut against the protective member.

[0011] Optionally, if the second box is located in the first position, at least a portion of the hinge section has an arc-shaped cross-section.

[0012] Optionally, the first box body includes a first flange structure, and the second box body includes a second flange structure. When the second box body is in the first position, the first flange structure abuts against the second flange structure. The second flange structure has a first notch, and the first flange structure includes a first abutting surface for abutting against the second flange structure. The first abutting surface has a first pressing portion. When the second box body is in the first position, the first pressing portion is exposed by the first notch. And / or, the first flange structure has a second notch, and the second flange structure includes a second abutting surface for abutting against the first flange structure. The second abutting surface has a second pressing portion. When the second box body is in the first position, the second pressing portion is exposed by the second notch.

[0013] Optionally, the first box body includes a first protrusion, and the second box body includes a second recess, wherein the first protrusion can engage with the second recess to position the second box body in a first position; and / or, the first box body includes a first recess, and the second box body includes a second protrusion, wherein the first recess can engage with the second protrusion to position the second box body in a first position.

[0071] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0073] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0074] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0075] In the accompanying diagram, directions X, Y, and Z are perpendicular to each other.

[0076] The image processing cartridge, a core component in imaging equipment (also known as a printer), is detachably installed within the device. It forms prints, such as text or images, on a printing medium (similar to paper). The quality of the image processing cartridge significantly impacts the reliability of the imaging equipment; therefore, newly manufactured cartridges require proper packaging to minimize the likelihood of contamination, breakage, or other issues affecting their quality.

[0077] In existing technologies, such as Figure 1The packaging member 30 shown is used to package the processing box 20. The packaging member 30 includes an upper box body 301, a lower box body 302, and a hinge structure 303. After the processing box 20 is packaged by the packaging member 30, the main body 201 of the processing box 20 occupies most of the space inside the packaging member 30. The gripping part 202 (the part for the user to grasp) of the processing box 20 can be offset in the lateral (direction Y) direction relative to the main body 201, so that the gripping part 202 is closer to the side wall of the packaging member 30. Of course, the gripping part 202 can also be offset in the height direction (direction Z) relative to the main body 201, so that the gripping part 202 is closer to the top wall of the packaging member 30. If the gripping part 202 is offset both in the lateral (direction Y) direction and in the height direction (direction Z) direction relative to the main body 201, then the gripping part 202 is closer to the top corner structure of the packaging member 30.

[0078] Among them, the longitudinal (length direction) of the processing box 20 is parallel to... Figure 1 The directions Z and Y are perpendicular.

[0079] During transportation, such as Figure 2 As shown, multiple packaging components 30 (prior art) containing processing boxes 20 need to be stacked in a packaging box (not shown in the figure) to... Figure 2 Taking the packaging component 30 in the lower left corner as an example, the upper right corner structure of the packaging component 30 in the lower left corner is prone to bearing loads from above, to the right, and to the upper right. If the gripping part 202 of the processing box 20 inside the packaging component 30 in the lower left corner is close to the upper right corner structure of the packaging component 30 in the lower left corner, correspondingly, the gripping part 202 of the processing box 20 inside the packaging component 30 in the lower left corner is also prone to bearing loads from above, to the right, and to the upper right. During transportation, there are often movements such as bumps, acceleration, and sudden stops. These movements can easily cause the gripping part 202 of the processing box 20 inside the packaging component 30 in the lower left corner to bear large impact loads, which can easily lead to structural problems such as plastic deformation, cracking, or breakage of the gripping part 202 of the processing box 20 inside the packaging component 30 in the lower left corner.

[0080] To address the aforementioned technical problems, this application provides a packaging box. Please refer to... Figures 3a-3f As shown, the packaging box 10 includes a first box body 1, a second box body 2, and a hinge part 3. Please refer to... Figure 4As shown, the first box body 1 includes a first receiving groove 11 for receiving at least a portion of the processing box (not shown in the figure). The first receiving groove 11 is provided with an inlet 11a, through which the processing box can be placed into the first receiving groove 11. The second box body 2 includes a second receiving groove 21 for receiving another portion of the processing box. The first box body 1 is rotatably connected to the second box body 2 via a hinge portion 3. The second box body 2 can be positioned relative to the first box body 1 at least as shown in the figure. Figure 3f The first position shown or as Figure 4 The second position shown, if the second box 2 is located as follows Figure 3f In the first position shown, the entrance 11a is closed by the second box 2. If the second box 2 is located as shown... Figure 4 In the second position shown, inlet 11a is in the open state. Therefore, it is possible to position the second box 2 as shown... Figure 4 In the second position shown, place the processing box into the first receiving slot 11, and then rotate the second box 2 as shown. Figure 3f The first position shown is for packaging box 10 to handle the packaging box. For example... Figure 5 As shown, the second box 2 is located in the first position, and the processing box 20 is packaged by the packaging box 10. Of course, the user can also... Figure 5 The second box 2, located in the first position, moves relative to the first box 1 to the position shown. Figure 4 The second position shown indicates that the user can remove the processing box 20 from the packaging box 10.

[0081] Please refer to Figure 6 As shown, the inner wall of the first receiving groove 11 includes a first protective part 111, which is used to protect the grip part 202. In the transverse direction (Y), the first protective part 111 is disposed in the inner wall of the first receiving groove 11 near the hinge part 3.

[0082] When the packaging box 10 containing the processing box 20 is subjected to the impact load of other packaging boxes located on the side, the structure of the hinge part 3 and the structure of the first box body 1 that is far away from the first protection part 111 in the Y direction bear the impact load before the first protection part 111. That is, the structure of the hinge part 3 and the structure of the first box body 1 that is far away from the first protection part 111 in the Y direction can play a good buffering role for the first protection part 111. Correspondingly, the grip part 202 protected by the first protection part 111 is not prone to structural problems such as plastic deformation, cracking or breakage.

[0083] In practice, when opening or closing the packaging box 10, the first box body 1 is kept relatively stationary while the second box body 2 moves relative to the first box body 1. Therefore, the common practice for placing the packaging box 10 is to position the first box body 1 below the second box body 2. Accordingly, the first protective part 111 is a structure located in the lower half of the packaging box 10. This arrangement allows the structure of the second box body 2 above to provide good cushioning for the first protective part 111 below when the packaging box 10 containing the processing box 20 is subjected to impact loads from other packaging boxes located above and to the upper right. This prevents the gripping part 202 protected by the first protective part 111 from structural problems such as plastic deformation, cracking, or breakage.

[0084] Alternatively, please refer to Figure 6 As shown, the first box 1 includes a first leg 12 that protrudes outward and in a direction away from the second box 2. In other words, the protrusion direction of the first leg 12 is the opposite of the direction Z. In the height direction (direction Z), the first protective part 111 is located between the first leg 12 and the hinge part 3.

[0085] When the packaging box 10 containing the processing box 20 is subjected to the impact load of other packaging boxes located below it, the first support leg 12 can provide good cushioning in the Z direction for the first protective part 111 and the grip part 202. Specifically, during transportation, if there is a vertical bumping motion, the load in the Z direction applied by other packaging boxes located below the packaging box 10 can be well cushioned by the first support leg 12, so that the first protective part 111 is not easily directly subjected to the impact load of the packaging boxes located below it, and correspondingly, so that the grip part 202 is not easily subjected to structural problems such as plastic deformation, cracking or breakage.

[0086] Alternatively, please refer to Figure 6 As shown, a predetermined connecting line (shown by dashed line O) exists between the first support leg 12 and the hinge portion 3, and a predetermined interval distance D1 exists between the first protective portion 111 and the connecting line (shown by dashed line O), satisfying 3mm ≤ D1 ≤ 10mm. The interval distance D1 can specifically be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm. With this configuration, the first protective portion 111 does not protrude relatively; therefore, the first protective portion 111 is less likely to directly bear the impact load from other packaging boxes. Correspondingly, the grip portion 202 protected by the first protective portion 111 is less prone to structural problems such as plastic deformation, cracking, or breakage.

[0087] Alternatively, please refer to Figure 7As shown, the second box body 2 includes a second leg 26 protruding outwards and in a direction opposite to the first box body 1. The second leg 26 is used to support the first leg of another packaging box located above it. As a protruding structure protruding in the Z direction, the second leg 26 can provide good cushioning in the Z direction for the first protective part 111 and the grip part 202. Specifically, during transportation, if there is a bumpy movement, the impact load applied by other packaging boxes located above the packaging box 10 in the opposite Z direction can be well cushioned by the second leg 26, so that the first protective part 111 is not easily directly subjected to the impact load of the packaging box located above it. Correspondingly, the grip part 202 protected by the first protective part 111 is also less likely to suffer structural problems such as plastic deformation, cracking or breakage.

[0088] Alternatively, please refer to Figure 6 As shown, the inner wall of the first receiving groove 11 also includes a second protective portion 112, which protects the main body portion 201. The first protective portion 111 is closer to the hinge portion 3 than the second protective portion 112. Figure 6 The first protective part 111 shown can support the gripping part 202, and the second protective part 112 can also support the main body part 201.

[0089] Alternatively, please refer to Figure 6 As shown, the first protective part 111 includes an intersecting first inner wall surface 111a and a second inner wall surface 111b. The first inner wall surface 111a and the second inner wall surface 111b have a set obtuse angle α, which satisfies 100°≤α≤160°.

[0090] Firstly, the obtuse angle α facilitates the smooth entry of the gripping part 202 into the first receiving groove 11 along the second inner wall surface 111b when the user places the processing box 20 into the first box body 1, and also facilitates the smooth detachment of the gripping part 202 from the first receiving groove 11 along the second inner wall surface 111b when the user removes the processing box 20 from the first box body 1. Secondly, the obtuse angle α can improve the bending strength of the first protective part 111, that is, the first protective part 111 can better resist the bending moment around the Z direction, and correspondingly, the bending strength of the first box body 1 is higher.

[0091] Specifically, the obtuse angle α can be 100°, 101°, 102°, 103°, 104°, 105°, 106°, 107°, 108°, 109°, 110°, 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 12... 9°, 130°, 131°, 132°, 133°, 134°, 135°, 136°, 137°, 138°, 139°, 140°, 141°, 142°, 143°, 144°, 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, 155°, 156°, 157°, 158°, 159°, or 160°. If the obtuse angle α is too small, for example, less than 100°, when placing the processing box 20 on the first box body 1 or removing the processing box 20 from the first box body 1, the gripping part 202 is prone to friction with the second inner wall surface 111b, which can easily lead to wear of at least one of the gripping part 202 and the first protective part 111. If the obtuse angle α is too large, for example, greater than 160°, the bending strength of the first protective part 111 will be low. Therefore, an obtuse angle α within the range of 100° to 160° is preferable.

[0092] Alternatively, please refer to Figure 6 As shown, the first inner wall surface 111a is inclined relative to the horizontal bottom surface 1a of the first box body 1, and there is a set acute angle β between the first inner wall surface 111a and the horizontal bottom surface 1a, satisfying 15°≤β≤45°. Specifically, the acute angle β can be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, or 45°. In this configuration, the first inner wall surface 111a, which is inclined relative to the horizontal bottom surface 1a, provides support for the grip portion 202 along the Z direction. Furthermore, the inclined inner wall surface 111a enhances the bending strength of the first housing 1, allowing it to better resist bending moments about the Z and Y directions. If the acute angle β is too small, for example, less than 15°, the bending strength of the first housing 1 is low. If the acute angle β is too large, for example, greater than 45°, the support provided by the first inner wall surface 111a for the grip portion 202 along the Z direction is weak. Therefore, an acute angle β within the range of 15° to 45° is preferable.

[0093] The aforementioned angle settings for the first inner wall surface 111a and the second inner wall surface 111b also have other advantages. For example, both the first inner wall surface 111a and the second inner wall surface 111b are inclined relative to the horizontal bottom surface 1a, forming a continuous buffer slope. During transportation, if the grip 202 sways relative to the first box body 1 in the Y direction, the grip 202 can move upward along the first inner wall surface 111a and / or the second inner wall surface 111b. In other words, the grip 202 can move in the Z direction. Gravity dissipates the kinetic energy of the grip 202, reducing the impact load between the grip 202 and the first protective part 111, thereby reducing the likelihood of structural problems such as plastic deformation, cracking, or breakage of the grip 202.

[0094] It should be noted that the horizontal bottom surface 1a serves as a reference surface for measuring the inclination angle of the first inner wall surface 111a. The horizontal bottom surface 1a can also be the bottom surface of a structure in the first box body 1 other than the first receiving groove 11. For example, the horizontal bottom surface 1a can be the bottom surface of the first support 12.

[0095] Alternatively, please refer to Figure 8 As shown, the processing cartridge 20 includes a protective member 203 for covering the developing component 204 (developing roller or photosensitive drum) of the processing cartridge 20. The inner wall of the second receiving groove 21 includes an inner protrusion structure 211, which protrudes into the receiving space of the second receiving groove 21. Alternatively, the outer surface of the second cartridge 2 has an outer recess structure 211a corresponding to the inner protrusion structure 211, and the recess direction of the outer recess structure 211a is the same as the protrusion direction of the protrusion structure 211. The inner protrusion structure 211 is used to abut against the protective component 203. During transportation, if there is impact movement between multiple packaging boxes 10, the impact load applied by other packaging boxes is not easily applied to the inner protrusion structure 211 or the outer recessed structure 211a. Accordingly, the protective component 203 is not easily deformed, cracked or broken by external loads, thereby reducing the possibility that the protective component 203 will come into contact with the developing component 204 (developing roller or photosensitive drum) and wear the developing component 204 (developing roller or photosensitive drum).

[0096] The second support leg 26, as a protruding structure along the Z direction, can effectively buffer the inner protruding structure 211 and the protective component 203 in the opposite Z direction. Specifically, during transportation, if there is vertical shaking, the load applied by other packaging boxes above the packaging box 10 in the opposite Z direction can be effectively buffered by the second support leg 26, so that the protective component 203 is less prone to structural problems such as deformation, cracking, or breakage.

[0097] It should be noted that since the multiple packaging boxes 10 inside the packaging box are stacked and arranged in a regular direction, the main impact load inside the packaging box is between the packaging boxes 10, and there is no load from particles or freely moving objects randomly impacting the packaging boxes 10.

[0098] In other embodiments, the structure of the first protective part 111 may also be as follows: Figure 9 As shown, a portion of the structure of the first inner wall surface 111a can be parallel to the horizontal bottom surface 1a. Please refer to... Figure 10 As shown, the first inner wall surface 111a also has a stepped structure 111aa. The stepped structure 111aa enables the first protective part 111 to better resist the bending moment around the Y direction, thereby improving the bending structural strength of the first inner wall surface 111a and the bending structural strength of the first protective part 111.

[0099] in, Figure 9 The first protective part 111 shown also serves to support the grip part 202.

[0100] In other embodiments, the structure of the first protective part 111 may also be as follows: Figure 11 As shown, the first inner wall surface 111a extends from the horizontal bottom surface 1a along the Y direction, meaning the first inner wall surface 111a serves as the lowest bottom wall within the first receiving groove 11. Figure 11 The first protective part 111 shown is not used to support the grip part 202, that is, when the packaging box 10 packages the processing box 20, the grip part 202 is suspended relative to the first protective part 111.

[0101] Figure 9 The first protective part 111 shown and Figure 11 The first protective parts 111 shown are all located close to the hinge part 3 in the lateral direction (direction Y) and are located between the hinge part 3 and the first support leg 12 in the height direction (direction Z).

[0102] Alternatively, please refer to Figure 11 As shown, when the second box 2 is in the first position, that is, when the second box 2 is closed on the first box 1, at least a portion of the structure of the hinge part 3 has an arc-shaped cross-section. Under this configuration, the hinge part 3 has high bending strength and can better resist impact loads, thereby enabling the hinge part 3 to provide good cushioning for the first protective part 111 and the gripping part 202.

[0103] It should be noted that, from a perspective along direction X, at least part of the structure of the hinge part 3 should be oblong in cross-sectional shape, so that the hinge part 3 can better resist bending moments about direction Z and about direction Y, and make the hinge part 3 weaker in resisting bending moments about direction X, thereby allowing the second box 2 to swing relative to the first box 1 about direction X.

[0104] When the second box 2 is in the second position, that is, when the second box 2 does not cover the first box 1, the cross-sectional shape of at least part of the hinge portion 3 can also be as follows: Figure 12 The bow shape shown.

[0105] In other embodiments, the cross-sectional shape of at least a portion of the hinge portion 3 may also be W-shaped, M-shaped, or N-shaped.

[0106] Alternatively, please refer to Figure 13 As shown, the first box 1 includes a first flange structure 13, and the second box 2 includes a second flange structure 22. When the second box 2 is in the first position, that is, when the second box 2 is closed to the first box 1, the first flange structure 13 can abut or fit against the second flange structure 22. Please refer to... Figure 13 As shown, the second flange structure 22 has a first notch 22a, and the first flange structure 13 includes a first abutting surface 131 for abutting against the second flange structure 22. The first abutting surface 131 has a first pressing portion 131a. When the second box 2 is in the first position, that is, when the second box 2 is closed on the first box 1, please refer to... Figure 14 As shown, the first pressing part 131a is exposed by the first notch 22a. In this configuration, one of the user's hands can grasp the second box 2, while the other hand presses the first pressing part 131a, so that the second box 2 can rotate relative to the first box 1 from a first position to a second position, that is, from a state in which the second box 2 is closed to the first box 1 to a state in which the second box 2 is not closed to the first box 1.

[0107] The embodiments of this application do not limit the specific shape of the first notch 22a. The notch area of ​​the first notch 22a is sufficient to allow the user's finger to press on the first pressing part 131a.

[0108] In other embodiments (not shown in the figures), the first flange structure may have a second notch, and the second flange structure may include a second abutting surface for abutting against the first flange structure. The second abutting surface has a second pressing portion, and when the second housing is in the first position, the second pressing portion is exposed by the second notch. In this configuration, one of the user's hands can grasp the first housing, and the other hand can press the second pressing portion to rotate the second housing relative to the first housing from the first position to the second position.

[0109] Alternatively, please refer to Figure 14 As shown, the outer surface of the second box 2 has an arrow mark 25. The user can move the second box 2 relative to the first box 1 under the guidance of the arrow mark 25, thereby correctly opening the packaging box 10 and reducing the possibility of damage to the processing box 20 due to incorrect opening of the packaging box 10.

[0110] Alternatively, please refer to Figure 13 As shown, the first box body 1 includes a first protrusion 14, and the second box body 2 includes a second recess 24. The first protrusion 14 can be interference-fitted with the second recess 24 so that the second box body 2 can remain stationary relative to the first box body 1 after being closed, thereby enabling the packaging box 10 to reliably package the processing box 20.

[0111] In a three-dimensional view, the first protrusion 14 can be cylindrical, and in a top-view view, the second recess 24 can be rectangular or rectangular with rounded corners. The diameter of the first protrusion 14 can be larger than the length or width of the second recess 24, so that the first protrusion 14 can be interference-fitted with the second recess 24.

[0112] Furthermore, when the diameter of the first protrusion 14 is greater than the width (dimension along direction X) of the second recess 24, and when the diameter of the first protrusion 14 is less than the length (dimension along direction Y) of the second recess 24, if either the first box 1 or the second box 2 is subjected to a load parallel to direction Y, the first protrusion 14 and the second recess 24 can slide relative to each other in a direction parallel to direction Y. The friction between the first protrusion 14 and the second recess 24 can consume external kinetic energy, thus providing a good buffering effect. This reduces the likelihood of structural problems such as plastic deformation, cracking, or breakage occurring in other parts of the box 20.

[0113] Furthermore, please refer to Figure 15 As shown, the first protrusion 14 includes at least two inwardly recessed reinforcing ribs 141. The reinforcing ribs 141 can improve the structural strength of the first protrusion 14, thereby reducing the likelihood of significant deformation during the mating process between the first protrusion 14 and the second recess 24, and thus reducing the possibility of interference fit failure between the first protrusion 14 and the second recess 24. The number of reinforcing ribs 141 can be at least three, and the at least three reinforcing ribs 141 are evenly distributed on the first protrusion 14.

[0114] In addition, please refer to Figure 15 As shown, the top of the first protrusion 14 includes a chamfered surface 142. The chamfered surface 142 makes it less likely for the top of the first protrusion 14 to get stuck when entering the second recess 24, thus allowing the first protrusion 14 to enter the second recess 24 more smoothly.

[0115] Alternatively, please refer to Figure 13As shown, the first box body 1 also includes a first recessed portion 15, and the second box body 2 also includes a second protrusion 23. The first recessed portion 15 can cooperate with the second protrusion 23 so that the second box body 2 covers the first box body 1 and keeps the second box body 2 stationary relative to the first box body 1.

[0116] The other shape, size, structure, and fitting configuration of the second protrusion 23 can be referenced to the configuration of the first protrusion 14 described above. Accordingly, the second protrusion 23 also has the technical effects of the first protrusion 14, which will not be repeated here. Similarly, the other shape, size, structure, and fitting configuration of the first recess 15 can be referenced to the configuration of the second recess 24 described above. Accordingly, the first recess 15 also has the technical effects of the second recess 24, which will not be repeated here.

[0117] Alternatively, please refer to Figure 13 As shown, the first protrusion 14 and the first recess 15 can be disposed on the first flange structure 13 of the first box body 1, and the second protrusion 23 and the second recess 24 can be disposed on the second flange structure 22 of the second box body 2. Of course, the first protrusion 14 and the first recess 15 can also be disposed at other positions of the first box body 1, and the second protrusion 23 and the second recess 24 can also be disposed at other positions of the second box body 2.

[0118] Alternatively, please refer to Figure 13 As shown, the first receiving slot 11 includes two limiting inclined surfaces 113 arranged opposite each other in the Y direction. When the packaging box 10 packages the processing box 20, and when the user rotates the first box body 1 relative to the second box body 2, the two limiting inclined surfaces 113 abut against the processing box 20 to limit the first box body 1 from continuing to rotate relative to the second box body 2, thereby preventing the user from accidentally opening the packaging box. Therefore, the user can only rotate the second box body 2 relative to the first box body 1 to open the packaging box 10 and take out the processing box 20, thereby preventing the processing box 20 from falling and being damaged when the user opens the packaging box 10 because it is not supported by the first box body 1.

[0119] The limiting inclined surface 113 is inclined relative to the second protective part 112 used to support the main body part 201.

[0120] Optionally, the first box 1, the second box 2, and the hinge part 3 are integrally formed (e.g., vacuum forming), and the first box 1, the second box 2, and the hinge part 3 are all made of resin.

[0121] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
