[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] In the various specific technical features described in the specific embodiments, without conflict, they can be combined in any appropriate manner. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination manners of the various specific technical features in the present utility model will not be described separately.

[0027] In the following description, the terms "first / second / ..." involved are only used to distinguish different objects and do not indicate that there are the same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", "inside" involved are all the orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state.

[0028] It should be noted that the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus including a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the phrase "including an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus including such element. The term "connected" includes both direct connection and indirect connection unless otherwise specified.

[0029] In the following specific embodiments, the packaging box provided can be used to accommodate any item. Exemplarily, the packaging box can be used to accommodate earphones. Exemplarily, the packaging box can also be used to accommodate a mobile phone. Exemplarily, the packaging box can also be used to accommodate a data cable. For the sake of convenience of description, hereinafter, it will be described by taking the packaging box for accommodating earphones as an example.

[0030] In some embodiments, as Figure 1 shown, the environmentally friendly packaging box 1 includes: a box body 100 and a box cover 200. The box body 100 has a receiving cavity 110, and an item is received in the receiving cavity 110. The receiving cavity 110 has an opening 111, and the item can be loaded into the receiving cavity 110 or taken out of the receiving cavity 110 through the opening 111. Moreover, the box body 100 further includes a first locking structure 120.

[0031] The box cover 200 is sleeved outside the box body 100 and can cover the opening 111. It can be understood that the opening of the receiving cavity 110 is located at the end of the box body 100, and the box cover 200 is sleeved outside the end and covers the opening 111. In the state where the box cover 200 covers 111, the item in the receiving cavity 110 cannot be taken out of the receiving cavity 110. At the same time, the box cover 200 can move relative to the box body 100 in a first direction (the first direction is as shown by the arrow in Figure 1 ). When the box cover 200 moves in the first direction, it can move the box cover 200 away from the opening 111, so as to remove the coverage of the box cover 200 on the opening 111. In the state where the box cover 200 removes the coverage of the opening 111, the item in the receiving cavity 110 can be taken out. Optionally, the box cover 200 is detachably connected to the box body 100, and the box cover 200 can be separated from the box body 100. Optionally, the box cover 200 is rotatably connected to the box body 100, and the rotation axis of the box cover 200 is perpendicular to the first direction. By relatively rotating the box cover 200 with respect to the box body 100, the box cover 200 can move relative to the box body 100 in the first direction.

[0032] Moreover, the lid 200 further includes a second locking structure 210. The second locking structure 210 can abut against the first locking structure 120. In a state where the first locking structure 120 and the second locking structure 210 are in abutment, the acting force between the first locking structure 120 and the second locking structure 210 can limit the movement of the lid 200 relative to the box body 100 in the first direction, and the first locking structure 120 and the second locking structure 210 can be unlocked, so that the lid 200 can move away from the box body 100 in the first direction and the lid 200 can remove the coverage of the opening 111. The specific structures of the first locking structure 120 and the second locking structure 210 will be described in combination with the unlocking structure in the subsequent content, so they will not be elaborated here.

[0033] Among them, the box body 100 includes a main body part 130 and an unlocking part 140. The main body part 130 has a first locking structure 120. It can be understood that the main body part 130 is used to accommodate articles and is used to connect with the box cover 200, and the first locking structure 120 is used to abut against the second locking structure 210 to limit the movement of the box cover 200 away from the main body part 130, so that the box cover 200 covers the opening 111 of the accommodating cavity 110; the unlocking part 140 can be separated from the main body part 130. The main body part 130 and the unlocking part 140 jointly surround to form the accommodating cavity 110. The unlocking part 140 includes an unlocking structure 141. The unlocking structure 141 can separate the first locking structure 120 from the second locking structure 210, so that the abutting force between the first locking structure 120 and the second locking structure 210 is removed. That is, the unlocking of the box cover 200 and the box body 100 is realized, and then the box cover 200 can move away from the box body 100 and the box cover 200 removes the coverage of the opening 111. It should be noted that the first locking structure 120 and the unlocking structure 141 are both parts of the box body 100, and the second locking structure 210 is a part of the box cover 200. The locking and unlocking between the box body 100 and the box cover 200 are realized through the structure of the packaging box 1 itself, so that there is no need to additionally set a sealing structure or a locking structure, and there is no need to set plastic to seal the packaging box 1, reducing the impact of the packaging box 1 on the environment; moreover, the outer surface of the unlocking structure 141 is flush with the outer surface of the main body part 130. The outer surfaces of the unlocking part 140 and the main body part 130 are both surfaces that can be directly touched by the user when the packaging box 1 is not opened. It can be understood that the unlocking part 140 will not have a part protruding from the main body part 130 due to the setting of the unlocking structure 141, so that the packaging box 100 has a flush outer surface and no locally protruding parts, improving the visual integrity of the appearance of the packaging box 100 and reducing the possibility of damage to the unlocking part 140 due to collision. Among them, the unlocking structure 141 can be integrally formed by the unlocking part 140, or the unlocking structure 141 can be a part of the unlocking part 140.Among them, the body part 130 and the unlocking part 140 can be detachably connected in any way. Exemplarily, the body part 130 and the unlocking part 140 are fixedly connected. The body part 130 has a window slot, and the unlocking part 140 is located in the window slot, and the outer contour of the unlocking part 140 matches the contour of the window slot. A connecting structure is provided between the inner edge of the window slot and the outer edge of the unlocking part 140, and the connecting structures are arranged at intervals along the outer contour of the unlocking part 140. During the process of the user tearing the unlocking part 140 from the body part 130, due to the interval arrangement of the connecting piece structures, the acting force applied by the user generates stress concentration at each connecting structure, so that the connecting structure breaks prior to the body part 130 and the unlocking part 140, so that the unlocking part 140 can be torn off from the body part 130 as a whole; Exemplarily, the unlocking part 140 and the body part 130 are connected by a magnetic attraction structure. By applying an acting force to the unlocking part 140 to overcome the magnetic attraction force between the unlocking part 140 and the body part 130, the unlocking part 140 can be separated from the body part 130. For the convenience of description, in the following embodiments, the connection between the body part 130 and the unlocking part 140 by the connecting structures arranged at intervals is taken as an example for description.

[0034] It should be noted that the first locking structure 120 and the second locking structure 210 can be any structure that can limit the movement of the box cover 200 away from the box body 100 through a resisting force. The unlocking structure 141 can be any structure that can make the first locking structure 120 and the second locking structure 210 move relative to each other and separate the first locking structure 120 and the second locking structure 210, so that the box cover 200 can move away from the box body 100. The unlocking structure 141 can make the first locking structure 120 and the second locking structure 210 move relative to each other by directly contacting the first locking structure 120 or the second locking structure 210. The unlocking structure 141 can also make the first locking structure 120 and the second locking structure 210 move relative to each other without directly contacting the first locking structure 120 and the second locking structure 210, and can apply an acting force to the first locking structure 120 or the second locking structure 210. And the structure of the unlocking structure 141 is adapted to the structures of the first locking structure 120 and the second locking structure 210. The following combines Figure 2 and Figure 3 , and the specific structures of the first locking structure 120, the second locking structure 210 and the unlocking structure 141 are described by way of example.

[0035] Such as Figure 2As shown, the first locking structure 120A of the first type includes a limiting groove 121A, and the second locking structure 210A of the first type includes a sliding groove 211A and a sliding block 212A. The sliding groove 211A communicates with the limiting groove 121, and the depth directions of both the limiting groove 121A and the sliding groove 211A are the first direction (the first direction is as shown by the solid arrow in Figure 2 ), the sliding block 212A is located in the sliding groove 211A and can slide in the width direction perpendicular to the first direction (the width direction is as shown by the dashed arrow in Figure 2 ). When the first locking structure 120A of the first type and the second locking structure 210A of the first type are in the locked state, a part of the sliding block 212A is located inside the limiting groove 121A, and the other part of the sliding block 212A extends out of the limiting groove 121A. When the lid 200 has a tendency to move away from the box body 100, the sliding block 121A abuts against the inner wall of the limiting groove 121A to limit the movement of the lid 200 away from the box body 100; at the same time, the part of the sliding block 212A extending out of the limiting groove 121A has an insertion groove 122A in the shape of a cylinder. The unlocking structure 141A of the first type is an unlocking column that can extend into the insertion groove 122A, and the lid 200 has an operation groove 220A for the unlocking column (the unlocking structure 141A of the first type). In the width direction, the size of the operation groove 210 is larger than the size of the unlocking column (the unlocking structure 141A of the first type). Pass the unlocking column (the unlocking structure 141A of the first type) through the operation groove 210 and into the inside of the insertion groove 122A. By sliding or yawing the unlocking column (the unlocking structure 141A of the first type), the sliding block 212A can be made to slide in the width direction and the part located in the limiting groove 121A can be moved out of the outside of the limiting groove 121A, so that the sliding block 212A is separated from the limiting groove 121A, that is, the first locking structure 120A of the first type is separated from the second locking structure 210A of the first type, realizing the unlocking of the first locking structure 120A of the first type and the second locking structure 210A of the first type. In this state, the lid 200 can move away from the box body 100 to remove the covering of Figure 1 the opening 111 in

[0036] As Figure 3 shown, the first locking structure 120B of the second type includes a receiving groove 121B, and the second locking structure 210B of the second type includes a limiting block 211B and a spring 212B. The depth direction of the receiving groove 121B is the first direction (the first direction is as shown by the solid arrow in Figure 3perpendicular to the arrow shown in the figure. The spring 212B is used to apply an elastic force to the limit block 211B and push the limit block 211B into the receiving groove 121B. At the same time, a metal that can be attracted by a magnet is provided on the surface of the limit block 211B facing away from the receiving groove 121B. When the first locking structure 120B of the second type and the second locking structure 210B of the second type are in a locked state, the limit block 211B is pushed into the receiving groove 121B by the spring 212B. When the lid 200 has a tendency to move away from the box body 100, the abutting force between the limit block 211B and the inner wall of the receiving groove 121B restricts the movement of the lid 200; the unlocking structure 141B of the second type is a magnet sheet, and the magnet sheet (the unlocking structure 141B of the second type) can attract the metal. When the magnet sheet (the unlocking structure 141B of the second type) is close to the position of the lid 200 where the limit block 211B is provided, the magnet sheet (the unlocking structure 141B of the second type) can use magnetic force to make the limit block 211B overcome the elastic force of the spring 212B and thus suck the limit block 211B out of the receiving groove 121B, that is, separate the first locking structure 120B of the second type from the second locking structure 210B of the second type, realizing the unlocking of the first locking structure 120B of the second type and the second locking structure 210B of the second type. In this state, the lid 200 can move away from the box body 100 to remove the Figure 1 covering of the opening 111 in the

[0037] An embodiment of the present utility model provides an environmentally friendly packaging box. The packaging box includes a box body having a receiving cavity with an opening, and the box body further includes a first locking structure. The packaging box further includes a lid sleeved outside the box body and capable of covering the opening. The lid can move relative to the box body in a first direction and remove the lid's covering of the opening, and the lid further includes a second locking structure. The second locking structure can abut against the first locking structure and restrict the movement of the lid relative to the box body in the first direction. That is, the packaging box realizes the locking of the packaging box through the locking structures of the lid and the box body itself, so that there is no need to additionally set a locking structure, and there is no need to set plastic for plastic sealing, reducing the impact of the packaging box on the environment. Among them, the box body includes a body part and an unlocking part. The body part and the unlocking part surround to form a receiving cavity, and the unlocking part includes an unlocking structure for separating the first locking structure and the second locking structure. That is, the packaging box also realizes the unlocking of the first locking structure and the second locking structure through the self-structure of the box body, without additionally setting an unlocking structure, further reducing the impact of the packaging box on the environment. Moreover, the outer surface of the unlocking part is flush with the outer surface of the body part, so that the outer surface of the box body forms an overall flush shape without local protrusions, improving the visual consistency of the appearance of the packaging box and also reducing the possibility of damage to the unlocking structure due to collision.

[0038] In some embodiments, such as Figure 4As shown, the unlocking structure 140 includes an unlocking body 142 and an operating structure 143. The unlocking body 142 includes an unlocking structure 141. The unlocking structure 141 can be a part of the unlocking body 142, and the unlocking structure 141 forms the entire unlocking body 142. The operating structure 143 protrudes from the unlocking body 142 along a second direction (the second direction is as shown by the arrow in Figure 4 ). The second direction is perpendicular to the thickness direction of the unlocking body 142. Among them, both the unlocking body 142 and the operating structure 143 are detachably connected to the body part 130, and the area of the outer surface of the operating structure 143 is smaller than the area of the outer surface of the unlocking body 142. It can be understood that the operating structure 143 protrudes from the unlocking body 142, and the area of the operating structure 143 is smaller than the area of the unlocking body 142, so that the connection area between the operating structure 143 and the body part 130 is smaller than the connection area between the unlocking body 142 and the body part 130, so that the operating structure 143 is more easily separated from the body part 130. In the case where the unlocking part 130 needs to be separated from the body part 140, the user can first separate the operating structure 143 from the body part 130, so that the operating structure 143. After separating the operating structure 143 from the body part 130, the operating structure 143 can form a handle structure protruding from the unlocking body 142, and the user can more easily apply a force to the unlocking body 142 through the operating structure 143 so that the unlocking body 142 is further separated from the body part 130. Moreover, the operating structure 143 protrudes from the unlocking body 142 and the operating structure 143 does not protrude along the thickness direction of the unlocking body 142, so that while applying a force to the unlocking body 142 through the operating structure 143, the outer surface of the operating structure 143 and the outer surface of the unlocking body 142 can be flush with the outer surface of the body part 130.

[0039] In some embodiments, as Figure 4 shown, the unlocking body 142 includes a fixed part 144 and an unlocking structure 141. The fixed part 142 is connected to the operating structure 143 and is detachably connected to the body part 130. The unlocking structure 141 is detachably connected to the fixed part 144. It can be understood that the unlocking structure 141 is a part of the unlocking body 142, and the unlocking structure 141 can be connected to the operating structure 143 through the fixed part 144, so that the shape and size of the unlocking body 142 are not restricted by the unlocking structure 141, and the design of the installation position of the unlocking body 142 and the connection position with the body part 130 is more free.

[0040] In some embodiments, as Figure 4As shown, the unlocking structure 141 is separably connected to the fixed part 144, that is, the unlocking structure 141 can be separated from the fixed part 144, so that the unlocking structure 141 can be disengaged from the fixed part 144, making the unlocking of the unlocking structure 141 more convenient. Among them, the separation between the unlocking structure 141 and the fixed part 144 can be achieved in different ways. Exemplarily, the fixed part 144 and the unlocking structure 141 are connected by a connecting structure, and this connecting structure can be damaged under the action of an external force, so that the fixed part 144 and the unlocking structure 141 are separated. Exemplarily, the fixed part 144 and the unlocking structure 141 are attracted by a magnetic structure, and the unlocking structure 141 can overcome the suction force of this magnetic structure under the action of an external force, so that the unlocking structure 141 is separated from the fixed part 144.

[0041] In some embodiments, as Figure 4 shown, the hardness of the unlocking structure 141 is greater than that of the fixed part 144. When the unlocking structure 141 needs to be in contact with Figure 1 the first locking structure 120 or the second locking structure 210 in it, the unlocking structure 141 with greater stiffness can more reliably separate the first locking structure 120 and the second locking structure 210. Moreover, the harder unlocking structure 141 can have greater structural strength, so that the unlocking structure 141 is less likely to be damaged during the process of repeated use. Optionally, the unlocking structure 141 and the fixed part 144 are separably connected, which enables the unlocking structure 141 and the fixed part 144 to be made of different materials. Specifically, the unlocking structure 141 is made of a hard material, and the fixed part 144 is made of a flexible material, so that while the unlocking structure 141 can reliably separate the first unlocking structure 120 and the second locking structure 210, the unlocking body 142 can generate an adaptive deformation according to the shape of the body part 130.

[0042] Optionally, the operation instructions of the packaging box are printed on the surface of the unlocking part 140, and the user is informed of the operation steps to unlock the packaging box 1 through the unlocking structure 141 in the form of a combination of diagrams and text.

[0043] In some embodiments, as Figure 5As shown, the main body 130 is a polygonal prism, which can be, for example, a cube, and the unlocking body 142 and the operating structure 143 are respectively located on both sides of the edge 132 of the polygonal prism. It can be understood that the unlocking body 142 and the operating structure 143 span an edge 132 of the polygonal prism, so that the unlocking body 142 and the operating structure 143 are respectively located on two adjacent faces of the polygonal prism, and the unlocking body 142 and the operating structure 143 are connected to form an integral unlocking part 140, so that after the operating structure 143 is separated from the main body 130, the operating structure 143 will be lifted up from the surface of the main body 130 under the action of the overall tension of the unlocking part 140, and the outer surface of the operating structure 143 will be flush with the outer surface of the unlocking body 142, so that the user can more conveniently further separate the unlocking body 142 from the main body 130 through the operating structure 143.

[0044] Optional, such as Figure 6 As shown, in Figure 5 After the unlocking portion 140 is separated from the main body portion 130, an observation window 133 is formed in the main body portion 130, and the user can observe the items in the accommodating cavity 110 through the observation window 133. It should be noted that the size of the observation window 133 is smaller than the size of the item, so that the item will not leak out of the accommodating cavity 110 through the observation window 133.

[0045] In some embodiments, Figure 7 As shown, the first locking structure 120 is rotatably connected to the main body portion 130 to form a connecting end 121, and the first locking structure 120 extends in a direction away from the main body portion 130 to form a free end 122. It can be understood that one end of the first locking structure 120 is rotatably connected to the main body portion 130 and the first locking structure 120 protrudes from the main body portion 130. Through the rotational movement of the first locking structure 120 relative to the main body portion 130, the distance between the first locking structure 120 and the main body portion 130 except the connecting end 121 can be changed; at the same time, the second locking structure 210 includes a lock The first locking structure 120 is located between the locking groove 211 and the body part 130, so that the first locking structure 120 can only swing within the space defined by the inner wall of the locking groove 211 and the body part 130, and the first locking structure 120 can abut against the side wall of the locking groove 211 in the first direction. It can be understood that when the first locking structure 120 and the second locking structure 210 have not been unlocked by the unlocking structure 141, the first locking structure 120 extends into the interior of the locking groove 211 and can abut against the side wall of the locking groove 211 in the first direction (the first direction is as shown in FIG. 14). Figure 7It abuts against the inner wall above (as shown by the arrow in the figure), so that during the movement of the lid 200 relative to the box body 100 in the first direction, the movement of the lid 200 can be restricted by the abutting force between the first locking structure 120 and the inner wall of the locking groove 211, so that the lid 200 maintains the coverage of the opening 111; moreover, in the first direction, the distance between the connecting end 121 and the opening 111 is not greater than the distance between the free end 122 and the opening 111. It can be understood that the first locking structure 120 extends in the direction away from the opening 111 to form the free end 122, so that the distance between the free end 122 and the opening 111 is greater than the distance between the connecting end 121 and the opening 111, or the first locking structure 120 extends in the direction perpendicular to the first direction, so that the distance between the free end 122 and the opening 111 is equal to the distance between the connecting end 121 and the opening 111. Thus, during the movement of the lid 200 relative to the box body 100 in the first direction, the distance between the first locking structure 120 and the body part 130 remains unchanged or gradually increases, so that the first locking structure 120 remains in the state of being located in the locking groove 211, and the first locking structure 120 and the locking groove 211 can maintain reliable abutment. The following combines Figure 7 and Figure 8 Exemplary descriptions are given of the structures of the first locking structures 120 extending in different directions, the principle of the first locking structure 120 realizing the locking of the box body 100 and the lid 200, and the principle of unlocking the box body 100 and the lid 200 through the unlocking structure 141.

[0046] Such as Figure 7As shown, the first rotation axis L1 of the first locking structure 120 is perpendicular to the first direction, and the first locking structure 120 forms a free end 122 in a direction away from the opening 111. It can be understood that the connecting end 121 of the first locking structure 120 is rotatably connected to the body part 130, the first rotation axis L1 is perpendicular to the first direction, and the first locking structure 120 extends in a direction away from the opening 111. At the same time, the free end 122 can abut against the side wall of the locking groove 211. During the movement of the lid 200 relative to the box body 100 in the first direction, under the action of the abutting force between the free end 122 and the side wall of the locking groove 211, the free end 122 of the first locking structure 120 rotates away from the body part 130 around the first rotation axis L1, so that the first locking structure 120 moves into the interior of the locking groove 211, and the rotational movement of the first locking structure 120 is restricted by the inner wall in the depth direction of the locking groove 211, so that the first locking structure 120 will not continue to rotate. It can be understood that during the movement of the lid 200 relative to the box body 100 in the first direction, the first locking structure 120 moves into the interior of the locking groove 211 in the depth direction, so that the first locking structure 120 is more reliably connected to the side wall of the locking groove 211, thereby locking the box body 100 and the lid 200 more reliably.

[0047] At the same time, the unlocking structure 141 is used to rotate the first locking structure 120 around the first rotation axis L1 and separate the free end 122 from the side wall of the locking groove 211. That is, the unlocking structure 141 is used to rotate the first locking structure 120 in a direction close to the body part 130, so that the part of the unlocking structure 141 located in the locking groove 211 moves to the outside of the locking groove 211, and further the free end 122 no longer contacts the inner wall of the locking groove 211, so that the lid 200 can continue to move relative to the box body 100 in the first direction, so that the lid 200 removes the coverage of the opening 111.

[0048] In some embodiments, such as Figure 7As shown, the lid 200 has a first operation hole 221 through which the unlocking structure 141 passes. The depth direction of the first operation hole 221 is parallel to the first direction. During the process of extending the unlocking structure 141 into the interior of the lid 200 along the first operation hole 221, the unlocking structure 141 can contact the first locking structure 120 and cause the free end 122 of the first locking structure 120 to rotate towards the body portion 130, so that the portion of the first locking structure 120 located in the locking groove 211 moves out of the locking groove 211, thereby realizing the unlocking of the box body 100 and the lid 200. Moreover, the unlocking structure 141 extends into the space between the first locking structure 120 and the body portion 130 from the side close to the connection end 121. That is, along the direction in which the unlocking structure 141 extends, the distance between the first locking structure 120 and the body portion 130 gradually decreases, thereby forming an inclined guiding structure by the first locking structure 120 and the body portion 130. This can not only reduce the possibility of movement interference between the unlocking structure 141 and the first locking structure 120 or the body portion 130, but also enable the unlocking structure 141 to reliably contact the first locking structure 120 and cause the first locking structure 120 to rotate towards the body portion 130.

[0049] In some embodiments, as Figure 8 shown, the second rotation axis L2 of the first locking structure 120 is parallel to the first direction (the first direction is as indicated by the arrow in Figure 8 . The outer surface of the first locking structure 120 in the first direction abuts against the side wall of the locking groove 211. It can be understood that the connection end 121 of the first locking structure 120 is rotatably connected to the body portion 130, and the second rotation axis L2 is parallel to the first direction. At the same time, the outer surface of the first locking structure 120 in the first direction abuts against the side wall of the locking groove 211. During the process of the lid 200 moving relative to the box body 100 in the first direction, the abutting force between the outer surface of the first locking structure 120 and the side wall of the locking groove 211 is in the direction of the second rotation axis L2, thereby reducing the possibility of the first locking structure 120 rotating around the second rotation axis L2, and further reducing the possibility of the first locking structure 120 moving out of the locking groove 211 due to rotation, so that the first locking structure 120 reliably abuts against the side wall of the locking groove 211.

[0050] Meanwhile, the unlocking structure 141 is configured to rotate the first locking structure 120 about the first rotation axis L2 and separate the free end 122 from the side wall of the locking groove 211. That is, the unlocking structure 141 is configured to rotate the first locking structure 120 in a direction approaching the body portion 130, so that the portion of the unlocking structure 141 located within the locking groove 211 moves outside the locking groove 211, and further the free end 122 no longer contacts the inner wall of the locking groove 211, enabling the lid 200 to continue to move relative to the box body 100 in the first direction, thereby removing the lid 200 from covering the opening 111.

[0051] In some embodiments, as Figure 8 shown, the lid 200 has a second operation hole 222 through which the unlocking structure 141 passes. The depth direction of the second operation hole 222 is perpendicular to the first direction, and in the depth direction of the second operation hole 222, the distance between the second operation hole 222 and the connection end 211 is greater than the distance between the second operation hole 222 and the free end 122. That is, along the direction in which the unlocking structure 141 extends, the distance between the first locking structure 120 and the body portion 130 gradually decreases, thereby forming an inclined guiding structure by the first locking structure 120 and the body portion 130, which can not only reduce the possibility of movement interference between the unlocking structure 141 and the first locking structure 120 or the body portion 130, but also enable the unlocking structure 141 to reliably contact the first locking structure 120 and rotate the first locking structure 120 in a direction approaching the body portion 130.

[0052] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
