Description

Technical Field

[0001] The present application relates to the technical field of printing device packaging, and particularly to a packaging box. Background Art

[0002] As a core component for imaging in an imaging device (also known as a printer), the processing cartridge can be detachably installed in the imaging device. The processing cartridge can form an imprint, such as text or an image, on a printing medium (similar to paper). The quality of the processing cartridge has a great influence on the working reliability of the imaging device. Therefore, newly produced processing cartridges need to be well packaged to reduce the possibility of problems affecting the quality of the processing cartridge, such as soiling and breakage. However, the structure of the packaging box in the prior art has defects in protecting the processing cartridge, and the structure of the processing cartridge is prone to structural problems such as plastic deformation, cracking or fracture. Summary of the Utility Model

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

[0004] The present application provides a packaging box for packaging a processing cartridge that can be detachably installed in an imaging device. The processing cartridge includes a main body portion and a holding portion, and the holding portion is offset to one side of the main body portion. The packaging box includes a first box body, a second box body and a hinge portion. The first box body includes a first receiving groove for receiving at least a part of the processing cartridge. The first receiving groove is provided with an entrance through which the processing cartridge can be placed in the first receiving groove. The second box body includes a second receiving groove for receiving the other part of the processing cartridge. The first box body is rotatably connected to the second box body through the hinge portion. Among them, 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 located in the first position, the entrance is closed by the second box body. If the second box body is located in the second position, the entrance is in an open state. The inner wall of the first receiving groove includes a first protection portion for protecting the holding portion, and the first protection portion is arranged close to the hinge portion in the inner wall of the first receiving groove.

[0005] When the packaging box with the processing cartridge bears the impact load of other packaging boxes on the side, the structures of the hinge part and the part of the first box body far from the first protection part both bear the impact load before the first protection part. That is, the structures of the hinge part and the part of the first box body far from the first protection part can play a good buffering role for the first protection part. Correspondingly, the holding part protected by the first protection part is not prone to structural problems such as plastic deformation, cracking or fracture. Among them, when opening or closing the packaging box, it is customary to keep the first box body relatively stationary and operate the second box body to move relative to the first box body. Therefore, the general placement habit of the packaging box is to place the first box body below the second box body. Correspondingly, the first protection part is a structure located in the lower half of the packaging box. This setting enables the packaging box with the processing cartridge to bear the impact load of other packaging boxes above and in the upper right. The structure of the second box body above can play a good buffering role for the first protection part below, so that the holding part protected by the first protection part is not prone to structural problems such as plastic deformation, cracking or fracture.

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

[0071] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0072] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0073] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "the" and "said" used in the embodiments of the present 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" used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A / and B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0075] In the accompanying drawings of the present application, direction X, direction Y and direction Z are perpendicular to each other pairwise.

[0076] As a core component for imaging in an imaging device (also known as a printer), the processing cartridge can be detachably installed in the imaging device. The processing cartridge can form imprints, such as characters or images, on a printing medium (similar to paper). The quality of the processing cartridge has a great influence on the working reliability of the imaging device. Therefore, newly produced processing cartridges need to be well packaged to reduce the possibility of problems affecting the quality of the processing cartridge, such as soiling and breakage.

[0077] In the prior art, such as Figure 1The packaging member 30 shown is used for packaging the processing cartridge 20. The packaging member 30 includes an upper box body 301, a lower box body 302, and a hinge structure 303. After the processing cartridge 20 is packaged by the packaging member 30, the main body portion 201 of the processing cartridge 20 occupies most of the space inside the packaging member 30. The holding portion 202 of the processing cartridge 20 (the portion for being grasped by a user) can be offset in the lateral direction (direction Y) with respect to the main body portion 201 such that the holding portion 202 is relatively close to the side wall of the packaging member 30. Of course, the holding portion 202 can also be offset in the height direction (direction Z) with respect to the main body portion 201 such that the holding portion 202 is relatively close to the top wall of the packaging member 30. If the holding portion 202 is offset both in the lateral direction (direction Y) and in the height direction (direction Z) with respect to the main body portion 201, then the holding portion 202 is relatively close to the corner structure of the packaging member 30.

[0078] Wherein, the longitudinal direction (length direction) of the processing cartridge 20 is perpendicular to Figure 1 the direction Z and the direction Y in

[0079] During transportation, as Figure 2 shown, it is necessary to stack and place a plurality of packaging members 30 (prior art) packaging the processing cartridge 20 in a packing box (not shown in the figure) for Figure 2 taking the packaging member 30 at the lower left corner in

[0080] As an example, the upper right corner structure of the packaging member 30 at the lower left corner is liable to bear the loads from above, from the right, and from the upper right. If the holding portion 202 of the processing cartridge 20 in the packaging member 30 at the lower left corner is close to the upper right corner structure of the packaging member 30 at the lower left corner, correspondingly, the holding portion 202 of the processing cartridge 20 in the packaging member 30 at the lower left corner is also liable to bear the loads from above, from the right, and from the upper right. During transportation, there are generally often motion states such as jolting, acceleration, and sudden stop, and such motion states are liable to cause the holding portion 202 of the processing cartridge 20 in the packaging member 30 at the lower left corner to bear a relatively large impact load, thereby liable to cause structural problems such as plastic deformation, cracking, or fracture of the holding portion 202 of the processing cartridge 20 in the packaging member 30 at the lower left corner.

[0080] In view of the above technical problems, an embodiment of the present application provides a packaging box. Please refer to Figures 3a - 3f shown, the packaging box 10 includes a first box body 1, a second box body 2, and a hinge portion 3. Please refer to Figure 4As shown, the first box body 1 includes a first receiving groove 11 for receiving at least a part of the processing cartridge (not shown in the figure). The first receiving groove 11 is provided with an entrance 11a through which the processing cartridge can be placed in the first receiving groove 11. The second box body 2 includes a second receiving groove 21 for receiving another part of the processing cartridge. The first box body 1 is rotatably connected to the second box body 2 through a hinge portion 3. Among them, the second box body 2 can be at least in a first position as shown in Figure 3f or a second position as shown in Figure 4 relative to the first box body 1. If the second box body 2 is in the first position as shown in Figure 3f , the entrance 11a is closed by the second box body 2. If the second box body 2 is in the second position as shown in Figure 4 , the entrance 11a is in an open state. Therefore, when the second box body 2 is in the second position as shown in Figure 4 , the processing cartridge can be placed into the first receiving groove 11, and then the second box body 2 is rotated to the first position as shown in Figure 3f so that the packaging box 10 packages the processing cartridge. As shown in Figure 5 , the second box body 2 is in the first position and the processing cartridge 20 is packaged by the packaging box 10. Of course, the user can also move the second box body 2 in the first position as shown in Figure 5 relative to the first box body 1 to the second position as shown in Figure 4 , and at this time the user can take out the processing cartridge 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 protection portion 111 for protecting the holding portion 202. In the transverse direction (direction Y), the first protection portion 111 is arranged close to the hinge portion 3 in the inner wall of the first receiving groove 11.

[0082] When the packaging box 10 with the processing cartridge 20 bears the impact load of other packaging boxes on the side, the structure of the hinge portion 3 and the structure of the first box body 1 far from the first protection portion 111 in the direction Y both bear the impact load first compared with the first protection portion 111. That is, the structure of the hinge portion 3 and the structure of the first box body 1 far from the first protection portion 111 in the direction Y can play a good buffering role for the first protection portion 111. Correspondingly, the holding portion 202 protected by the first protection portion 111 is not likely to have structural problems such as plastic deformation, cracking or fracture.

[0083] Among them, when opening or closing the packaging box 10, it is customary to keep the first box body 1 relatively stationary and operate the second box body 2 to move relative to the first box body 1. Therefore, generally, the placement habit of the packaging box 10 is to place the first box body 1 below the second box body 2. Correspondingly, the first protection part 111 is a structure located in the lower half of the packaging box 10. This setting enables the structure of the second box body 2 located above to play a good buffering role for the first protection part 111 located below when the packaging box 10 containing the processing box 20 bears the impact load of other packaging boxes located above and upper right, so that the holding part 202 protected by the first protection part 111 is not prone to structural problems such as plastic deformation, cracking or fracture.

[0084] Optionally, please refer to Figure 6 As shown, the first box body 1 includes a first support leg 12 that protrudes outward and in a direction away from the second box body 2. That is to say, the protruding direction of the first support leg 12 is the reverse of the direction Z. In the height direction (direction Z), the first protection part 111 is located between the first support leg 12 and the hinge part 3.

[0085] When the packaging box 10 containing the processing box 20 bears the impact load of other packaging boxes located below, the first support leg 12 can play a good buffering role for the first protection part 111 and the holding part 202 in the direction Z. Specifically, during transportation, if there is an up-and-down bumpy motion state, the load along the direction Z applied by other packaging boxes located below the packaging box 10 can be well buffered by the first support leg 12, so that the first protection part 111 is not easily directly subjected to the impact load of the packaging box located below. Correspondingly, the holding part 202 is not prone to structural problems such as plastic deformation, cracking or fracture.

[0086] Optionally, please refer to Figure 6 As shown, there is a set connection line (shown by the dotted line O) between the first support leg 12 and the hinge part 3, and there is a set spacing distance D1 between the first protection part 111 and the connection line (shown by the dotted line O), satisfying 3mm ≤ D1 ≤ 10mm. The spacing distance D1 can specifically be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm. With this setting, the first protection part 111 does not protrude relatively. Therefore, the first protection part 111 is not easily directly subjected to the impact load of other packaging boxes. Correspondingly, the holding part 202 protected by the first protection part 111 is also not prone to structural problems such as plastic deformation, cracking or fracture.

[0087] Optionally, please refer to Figure 7As shown, the second box body 2 includes a second supporting leg 26 that protrudes outward and in a direction away from the first box body 1. The second supporting leg 26 is used to support the first supporting leg of another packaging box located above. As a protruding structure protruding along the direction Z, the second supporting leg 26 can play a good buffering role for the first protection part 111 and the holding part 202 in the direction Z. Specifically, during transportation, if there is an up-and-down bumpy motion state, the impact load applied in the direction opposite to the direction Z by other packaging boxes located above the packaging box 10 can be well buffered by the second supporting leg 26, so that the first protection part 111 is not easily directly subjected to the impact load of the packaging box above. Correspondingly, the holding part 202 protected by the first protection part 111 is not easily deformed plastically, cracked or broken and other structural problems.

[0088] Optionally, please refer to Figure 6 As shown, the inner wall of the first receiving groove 11 further includes a second protection part 112, and the second protection part 112 is used to protect the main body part 201. The first protection part 111 is closer to the hinge part 3 than the second protection part 112. Among them, Figure 6 the first protection part 111 shown in

[0089] Optionally, please refer to Figure 6 As shown, the first protection part 111 includes an intersecting first inner wall surface 111a and a second inner wall surface 111b. There is a set obtuse angle α between the first inner wall surface 111a and the second inner wall surface 111b, satisfying 100° ≤ α ≤ 160°.

[0090] In the first aspect, the setting of the obtuse angle α facilitates the user to make the holding part 202 enter the first receiving groove 11 more smoothly along the second inner wall surface 111b when placing the processing box 20 on the first box body 1, and also facilitates the user to make the holding part 202 smoothly disengage from the first receiving groove 11 along the second inner wall surface 111b when taking out the processing box 20 from the first box body 1; in the second aspect, the setting of the obtuse angle α can improve the bending resistance structural strength of the first protection part 111, that is, the first protection part 111 can better resist the bending moment around the direction Z. Correspondingly, the first box body 1 has a higher bending resistance structural strength.

[0091] Among them, the obtuse angle α can specifically 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°, 129°, 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, the obtuse angle α is less than 100°, when the processing cartridge 20 is placed on the first cartridge body 1 or when the processing cartridge 20 is taken out from the first cartridge body 1, it is easy for the holding portion 202 to rub against the second inner wall surface 111b, thus easily causing wear of at least one of the holding portion 202 and the first protection portion 111. If the obtuse angle α is too large, for example, the obtuse angle α is greater than 160°, the bending resistance structural strength of the first protection portion 111 is relatively low. Therefore, it is better that the obtuse angle α is in the range of 100° to 160°.

[0092] Optionally, please refer to Figure 6 As shown, the first inner wall surface 111a is inclined with respect to the horizontal bottom surface 1a of the first cartridge 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°. Among them, the acute angle β can specifically 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 setting, on the one hand, the first inner wall surface 111a inclined with respect to the horizontal bottom surface 1a can play a supporting role in the Z direction for the holding portion 202. On the other hand, the first inner wall surface 111a inclined with respect to the horizontal bottom surface 1a can improve the bending resistance structural strength of the first cartridge body 1, so that the first cartridge body 1 can better resist the bending moments around the Z direction and the Y direction. If the acute angle β is too small, for example, the acute angle β is less than 15°, the bending resistance structural strength of the first cartridge body 1 is relatively small. If the acute angle β is too large, for example, the acute angle β is greater than 45°, the supporting effect of the first inner wall surface 111a on the holding portion 202 in the Z direction is relatively small. Therefore, it is better that the acute angle β is in the range of 15° to 45°.

[0093] The above-mentioned angular setting of the first inner wall surface 111a and the second inner wall surface 111b also has other advantages. For example, both the first inner wall surface 111a and the second inner wall surface 111b are inclined surfaces relative to the horizontal bottom surface 1a, so that the first inner wall surface 111a and the second inner wall surface 111b form a continuous buffer slope. During transportation, if the holding portion 202 shakes relative to the first box body 1 in the direction Y, the holding portion 202 can move upward along the first inner wall surface 111a and / or the second inner wall surface 111b. In other words, the movement of the holding portion 202 has a movement in the direction Z. The kinetic energy of the holding portion 202 is consumed by the action of gravity to reduce the impact load between the holding portion 202 and the first protection portion 111, thereby reducing the possibility of structural problems such as plastic deformation, cracking or fracture of the holding portion 202.

[0094] It should be noted that the horizontal bottom surface 1a is used 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 the structure in the first box body 1 other than the first accommodating groove 11. For example, the horizontal bottom surface 1a can be the bottom surface of the first support leg 12.

[0095] Optionally, please refer to Figure 8 As shown, the processing cartridge 20 includes a protection member 203 for covering a developing member 204 (developing roller or photosensitive drum) of the processing cartridge 20. The inner wall of the second accommodating groove 21 includes an inner convex structure 211. The inner convex structure 211 protrudes into the accommodating space of the second accommodating groove 21. In other words, there is an outer concave structure 211a corresponding to the inner convex structure 211 on the outer surface of the second box body 2. The concave direction of the outer concave structure 211a is the same as the protruding direction of the convex structure 211. The inner convex structure 211 is used to abut against the protection member 203. During transportation, if there is an impact movement between multiple packaging boxes 10, the impact load applied by other packaging boxes is not easily applied to the inner convex structure 211 or the outer concave structure 211a. Correspondingly, the protection member 203 is not easily deformed, cracked or broken due to external loads, thereby reducing the possibility of the protection member 203 contacting the developing member 204 (developing roller or photosensitive drum) and wearing the developing member 204 (developing roller or photosensitive drum).

[0096] Among them, the second support leg 26 is a convex structure protruding in the direction Z. The second support leg 26 can play a good buffering role for the inner convex structure 211 and the protection member 203 in the reverse direction Z. Specifically, during transportation, if there is an up-and-down bumpy movement state, the load applied in the reverse direction Z by other packaging boxes located above the packaging box 10 can be well buffered by the second support leg 26, so that the protection member 203 is not easily deformed, cracked or broken.

[0097] It should be noted that since the multiple packaging boxes 10 in the packaging case are stacked and arranged in a regular direction, the impact load mainly occurs between the packaging box 10 and the packaging box 10 in the packaging case, and there is no load of particulate matter or freely moving objects randomly hitting the packaging box 10.

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

[0099] Among them, Figure 9 the shown first protection part 111 is also used to support the holding part 202.

[0100] In other embodiments, the structure of the first protection part 111 can also be as Figure 11 shown. The first inner wall surface 111a extends from the horizontal bottom surface 1a along the direction Y, that is, the first inner wall surface 111a is the bottom wall with the lowest height in the first receiving groove 11. Among them, Figure 11 the shown first protection part 111 is not used to support the holding part 202, that is, when the packaging box 10 packages the processing box 20, the holding part 202 is suspended relative to the first protection part 111.

[0101] Figure 9 the shown first protection part 111 and Figure 11 the shown first protection part 111 are both close to the hinge part 3 in the transverse direction (direction Y) and are located between the hinge part 3 and the first support leg 12 in the height direction (direction Z).

[0102] Optionally, please refer to Figure 11 shown. When the second box body 2 is in the first position, that is, when the second box body 2 covers the first box body 1, the cross-sectional shape of at least part of the structure of the hinge part 3 is in a bow shape. In this setting, the hinge part 3 has a relatively high bending structural strength, and the hinge part 3 can better resist the impact load, so that the hinge part 3 can play a good buffering role for the first protection part 111 and the holding part 202.

[0103] It should be noted that the cross-sectional shape of at least part of the structure of the hinge part 3 can be observed from the perspective along the direction X, so that the hinge part 3 can better resist the bending moment around the direction Z and the bending moment around the direction Y, and the performance of the hinge part 3 in resisting the bending moment around the direction X is relatively weak, so that the second box body 2 can swing relative to the first box body 1 around the direction X.

[0104] When the second box body 2 is in the second position, that is, when the second box body 2 is not covered on the first box body 1, the cross-sectional shape of at least part of the hinge portion 3 may also be in the shape of a bow as shown in Figure 12 .

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

[0106] Optionally, as shown in Figure 13 , the first box body 1 includes a first flanging structure 13, and the second box body 2 includes a second flanging structure 22. When the second box body 2 is in the first position, that is, when the second box body 2 covers the first box body 1, the first flanging structure 13 may abut or fit against the second flanging structure 22. As shown in Figure 13 , the second flanging structure 22 has a first notch 22a, the first flanging structure 13 includes a first abutting surface 131 for abutting against the second flanging structure 22, and the first abutting surface 131 has a first pressing portion 131a. When the second box body 2 is in the first position, that is, when the second box body 2 covers the first box body 1, as shown in Figure 14 , the first pressing portion 131a is exposed by the first notch 22a. In this setting, one hand of the user can grasp the second box body 2, and the other hand presses the first pressing portion 131a, so that the second box body 2 rotates relative to the first box body 1 from the first position to the second position, that is, the state where the second box body 2 covers the first box body 1 can be changed to the state where the second box body 2 does not cover the first box body 1.

[0107] The embodiment of the present application does not limit the specific shape of the first notch 22a, and the notch area of the first notch 22a can satisfy that the user's finger can press on the first pressing portion 131a.

[0108] In other embodiments (not shown in the figure), the first flanging structure may have a second notch, the second flanging structure may include a second abutting surface for abutting against the first flanging structure, the second abutting surface has a second pressing portion, and when the second box body is in the first position, the second pressing portion is exposed by the second notch. In this setting, one hand of the user can grasp the first box body, and the other hand presses the second pressing portion, so that the second box body rotates relative to the first box body from the first position to the second position.

[0109] Optionally, as shown in Figure 14 , the outer surface of the second box body 2 has an arrow mark 25, and the user can move the second box body 2 relative to the first box body 1 under the guidance of the arrow mark 25, so as to correctly open the packaging box 10 and reduce the possibility of damaging the processing box 20 due to incorrect opening of the packaging box 10.

[0110] Optionally, please refer to Figure 13 As shown, the first box body 1 includes a first convex portion 14, and the second box body 2 includes a second concave portion 24. The first convex portion 14 can be in interference fit with the second concave portion 24, so that the second box body 2 can remain stationary relative to the first box body 1 after being covered on the first box body 1, thereby enabling the packaging box 10 to reliably package the processing box 20.

[0111] Among them, from a three-dimensional perspective, the shape of the first convex portion 14 can be a cylinder, and from a top view perspective, the shape of the second concave portion 24 can be a rectangle or a rectangle with rounded corners. The diameter dimension of the first convex portion 14 can be greater than the length dimension or width dimension of the second concave portion 24, so that the first convex portion 14 can be in interference fit with the second concave portion 24.

[0112] In addition, when the diameter dimension of the first convex portion 14 is greater than the width dimension (dimension along direction X) of the second concave portion 24, and when the diameter dimension of the first convex portion 14 is less than the length dimension (dimension along direction Y) of the second concave portion 24, if either the first box body 1 or the second box body 2 bears a load parallel to direction Y, the first convex portion 14 and the second concave portion 24 can frictionally slide relative to each other in a direction parallel to direction Y. The friction between the first convex portion 14 and the second concave portion 24 can consume external kinetic energy, that is, it can play a good buffering role, and the possibility of structural problems such as plastic deformation, cracking or fracture in other parts of the processing box 20 is relatively low.

[0113] Furthermore, please refer to Figure 15 As shown, the first convex portion 14 includes at least two inwardly concave reinforcing ribs 141. The reinforcing ribs 141 can improve the structural strength of the first convex portion 14, so as to reduce the possibility of large deformation during the cooperation between the first convex portion 14 and the second concave portion 24, thereby reducing the possibility of failure of the interference fit between the first convex portion 14 and the second concave portion 24. The number of the reinforcing ribs 141 can be at least three, and at least three reinforcing ribs 141 are evenly distributed on the first convex portion 14.

[0114] In addition, please refer to Figure 15 As shown, the top end of the first convex portion 14 includes a chamfered surface 142. The setting of the chamfered surface 142 can prevent the top end of the first convex portion 14 from getting stuck easily during the process of entering the second concave portion 24, so that the first convex portion 14 can enter the second concave portion 24 more smoothly.

[0115] Optionally, please refer to Figure 13As shown, the first box body 1 further includes a first recess 15, and the second box body 2 further includes a second protrusion 23. The first recess 15 can cooperate with the second protrusion 23 to cover the second box body 2 on the first box body 1 and keep the second box body 2 stationary relative to the first box body 1.

[0116] For other shape settings, dimension settings, structural settings, and cooperation settings of the second protrusion 23, reference can be made to the settings of the first protrusion 14 in the above text. Correspondingly, the second protrusion 23 also has the technical effects of the first protrusion 14, which will not be elaborated here. Similarly, for other shape settings, dimension settings, structural settings, and cooperation settings of the first recess 15, reference can be made to the settings of the second recess 24 in the above text. Correspondingly, the first recess 15 also has the technical effects of the second recess 24, which will not be elaborated here.

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

[0118] Optionally, please refer to Figure 13 As shown, the first receiving groove 11 includes two limiting inclined surfaces 113 that are oppositely arranged in the Y direction. When the packaging box 10 packages the processing box 20 and when the user operates the first box body 1 to rotate relative to the second box body 2, the two limiting inclined surfaces 113 are in limiting contact with the processing box 20 to limit the continuous rotation of the first box body 1 relative to the second box body 2, thereby preventing the user from mistakenly opening the packaging box. Therefore, the user can only operate the second box body 2 to rotate 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 because it is not supported by the first box body 1 when the user opens the packaging box 10.

[0119] Among them, the limiting inclined surface 113 is inclined relative to the second protection portion 112 for supporting the main body portion 201.

[0120] Optionally, the first box body 1, the second box body 2, and the hinge portion 3 are integrally formed (such as by thermoforming), and the materials of the first box body 1, the second box body 2, and the hinge portion 3 are all resin materials.

[0121] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
