[0036] This application provides a storage box 10, as shown in Figures 1 to 4. The storage box 10 includes a first cover 100 and a second cover 200. The second cover 200 cooperates with the first cover 100 to form a receiving cavity 101 for storing items. The first cover 100 has a first mating portion 110, and the second cover 200 has a second mating portion 210. The second cover 200 can rotate relative to the first cover 100 so that the second mating portion 210 aligns with the first mating portion 110. The second cover 200 is configured such that when the second mating portion 210 is aligned with the first mating portion 110, it can move away from or closer to the first cover 100 along the rotation axis L of the second cover 200 to open or close the storage box 10. The second cover 200 is also configured such that when the second mating portion 210 is not aligned with the first mating portion 110, the second cover 200 forms a snap-fit ​​engagement with the first cover 100 along the rotation axis L to lock the storage box. During the opening and closing of the storage box 10, the first mating part 110 and the second mating part 210 need to be aligned so that the second cover 200 can be removed from or installed on the first cover 100 along the rotation axis L. When the second cover 200 is installed on the first cover 100, it can rotate relative to the first cover 100, causing the second mating part 210 to misalign with the first mating part 110. The second cover 200 and the first cover 100 then form a snap-fit ​​engagement along the rotation axis L to lock the storage box 10. By setting the first mating part 110 and the second mating part 210, the storage box 10 needs to be rotated and aligned during opening and closing, thereby achieving a child lock effect. This effectively prevents children from accessing the items inside the storage cavity 101, improving the safety and reliability of the storage box 10.

[0037] In some embodiments, the storage box 10 includes an open state and a closed state. When the storage box 10 is in the open state, the first cover 100 and the second cover 200 are separated, and the accommodating cavity 101 is in communication with the outside. When the storage box 10 is in the closed state, the first cover 100 and the second cover 200 are connected, and the accommodating cavity 101 is in a closed state and is not in communication with the outside.

[0038] In some embodiments, as shown in Figures 7 and 9, the first cover 100 includes a first bottom wall 120 and a first side wall 130, the first side wall 130 being disposed around the first bottom wall 120, and the second cover 200 includes a second bottom wall 220 and a second side wall 230, the second side wall 230 being disposed around the second bottom wall 220.

[0039] In some embodiments, when the storage box 10 is in the closed state, the first side wall 130 and the second bottom wall 220 abut against each other to ensure that the accommodating cavity 101 is completely sealed and to improve the sealing effect of the storage box 10.

[0040] In some embodiments, the accommodating cavity 101 can be used to store oral products, atomizing devices, and other items that require high sealing and safety during storage.

[0041] In some embodiments, the storage box 10 is generally cylindrical to allow the second cover 200 to rotate relative to the first cover 100.

[0042] In some embodiments, as shown in Figures 7 to 9, a groove 1301 is provided at one end of the first sidewall 130 away from the first bottom wall 120. The groove 1301 extends circumferentially along the first cover 100. A second mating portion 210 protrudes from the second sidewall 230 and is configured to slidably connect with the groove 1301. When the storage box 10 is in the closed state, the second mating portion 210 and the groove 1301 are slidably connected. When the first cover 100 and the second cover 200 rotate relative to each other, the second mating portion 210 slides along the groove 1301. A third sidewall 135 is provided on the side of the groove 1301 away from the first bottom wall 120. The third sidewall 135 and the second mating portion 210 form a snap-fit ​​engagement in the direction of the rotation axis L.

[0043] In some embodiments, the first mating portion 110 includes a groove provided on the third sidewall 135, the first mating portion 110 communicates with the slide groove 1301, and the second mating portion 210 is configured to pass through the first mating portion 110 and move circumferentially along the first cover 100 to the slide groove 1301. In some embodiments, the second mating portion 210 can be inserted into the first mating portion 110 along the direction of the rotation axis L, so that the second mating portion 210 and the first mating portion 110 are aligned. At this time, the second cover 200 can rotate relative to the first cover 100, so that the second mating portion 210 moves from the first mating portion 110 into the slide groove 1301.

[0044] In some embodiments, the first docking portion 110 and the slide groove 1301 are disposed on the side of the first sidewall 130 away from the receiving cavity 101, and the second docking portion 210 is disposed on the side of the second sidewall 230 close to the receiving cavity 101.

[0045] In some other embodiments, the first docking portion 110 may also be a protrusion protruding from the first sidewall 130, the second docking portion 210 may be a groove, the slide groove 1301 may be provided on the second sidewall 230, the second docking portion 210 and the slide groove 1301 may communicate, and the first docking portion 110 may be configured to pass through the second docking portion 210 and slide in the slide groove 1301.

[0046] In some embodiments, a buffer portion 131 is provided at one end of the slide 1301 near the first docking portion 110. The buffer portion 131 protrudes from the first sidewall 130, and the thickness of the buffer portion 131 along the radial direction of the first cover 100 is less than the thickness of the third sidewall 135 along the radial direction of the first cover 100. The buffer portion 131 is used to hinder the sliding of the second docking portion 210 when it slides from the slide 1301 to the first docking portion 110. When the user rotates the second cover 200, they can sense the resistance of the buffer portion 131 to the rotation of the second cover 200, and thus determine that the second docking portion 210 will be aligned with the first docking portion 110. The buffer portion 131 can remind the user of the rotation position of the second cover 200, making the operation more convenient and improving the user experience. At the same time, the buffer portion 131 can make the locking state of the storage box 10 more stable, preventing children from easily rotating and unlocking it, further improving the safety and reliability of the storage box 10.

[0047] In some embodiments, a stop portion 132 is provided at one end of the first docking portion 110 away from the buffer portion 131, and the stop portion 132 is disposed between the slide groove 1301 and the first docking portion 110.

[0048] In some embodiments, a buffer portion 131 is disposed at the inlet end of the slide groove 1301, and a stop portion 132 is disposed at the end of the slide groove 1301. The thickness of the stop portion 132 along the radial direction of the first cover 100 is greater than the thickness of the buffer portion 131 along the radial direction of the first cover 100. When the second mating portion 210 and the first mating portion 110 are aligned, the second cover 200 can rotate relative to the first cover 100 in a first direction, and the second mating portion 210 can move into the slide groove 1301 via the buffer portion 131. When the second cover 200 rotates in a second direction opposite to the first direction, the second mating portion 210 is blocked by the stop portion 132 and cannot move further in the second direction. When the user rotates the second cover 200 in the second direction until the second mating portion 210 and the stop portion 132 abut against each other, it indicates that the second mating portion 210 and the first mating portion 110 are aligned. At this time, the second cover 200 can be removed and the storage box 10 can be opened. The stop part 132 can improve the opening efficiency of the storage box 10.

[0049] In some embodiments, there are multiple first docking portions 110 and multiple second docking portions 210, and the multiple first docking portions 110 and the multiple second docking portions 210 correspond one-to-one.

[0050] In some embodiments, there are two first docking portions 110 and two second docking portions 210, and there are also two sliding grooves 1301. The two sliding grooves 1301 are respectively disposed at both ends of the first docking portion 110, and the multiple first docking portions 110 and the multiple sliding grooves 1301 are sequentially and alternately connected along the circumference of the first cover 100.

[0051] In some embodiments, as shown in Figures 5, 6, and 9, a limiting wall 240 is connected to the second bottom wall 220. The limiting wall 240 extends circumferentially along the second bottom wall 220. A first connecting groove 201 is formed between the limiting wall 240 and the second side wall 230. The first side wall 130 is configured to be inserted into the first connecting groove 201. The limiting wall 240 can restrict the radial movement range of the first side wall 130 along the second cover 200, making the connection between the first cover 100 and the second cover 200 tighter. The second mating portion 210 is less likely to disengage from the sliding groove 1301, making the connection between the first cover 100 and the second cover 200 more stable and tighter. This is beneficial to improving the sealing and moisture-proof performance of the storage box 10 when it is closed, so as to better preserve oral products.

[0052] In some embodiments, when the first sidewall 130 is inserted into the first connecting groove 201, the second cover 200 has a first state and a second state.

[0053] In the first state, the second docking part 210 is aligned with the first docking part 110, and the second cover 200 can move away from or closer to the first cover 100 along the direction of the rotation axis to open or close the storage box 10.

[0054] In the second state, the second docking part 210 is circumferentially offset from the first docking part 110, and the second cover 200 and the first cover 100 form a snap-fit ​​engagement to lock the storage box 10.

[0055] In some embodiments, the second cover 200 is provided with a reinforcing portion 250, which is connected to the second bottom wall 220 and the second side wall 230. The reinforcing portion 250 can strengthen the second cover 200, making the second bottom wall 220 and the second side wall 230 less prone to deformation, and making the structure of the storage box 10 more stable.

[0056] In some embodiments, there are multiple reinforcing parts 250, and the multiple reinforcing parts 250 are arranged sequentially along the circumference of the second cover 200.

[0057] In some embodiments, the reinforcing part 250 is disposed in the first connecting groove 201, and a second connecting groove 202 is formed between the reinforcing part 250 and the limiting wall 240. The reinforcing part 250 has an inclined surface 251 at one end away from the second bottom wall 220, and the inclined surface 251 is used to guide the first side wall 130 to be inserted into the second connecting groove 202.

[0058] In some embodiments, the first sidewall 130 includes a plug portion 133 located on the side of the third sidewall 135 opposite to the first bottom wall 120. The plug portion 133 is configured to be inserted into the second connecting groove 202 and abut against the second bottom wall 220. In some embodiments, the plug portion 133 is located at the end of the first sidewall 130 away from the first bottom wall 120, and the plug portion 133 can be inserted into the second connecting groove 202 under the guidance of the inclined surface 251.

[0059] In some embodiments, the third sidewall 135 is provided with a connecting surface 134 that connects to the insertion portion 133, and the connecting surface 134 cooperates with the inclined surface 251. In some embodiments, the inclined surface 251 is connected to the second sidewall 230 and inclined towards the second bottom wall 220, and the connecting surface 134 and the inclined surface 251 are parallel. The inclined surface 251 allows the reinforcing portion 250 and the second sidewall 230 to have a larger connection area, which can reduce the space occupied by the reinforcing portion 250 while improving the strength of the second cover 200. The connecting surface 134 can cooperate with the inclined surface 251 while ensuring the strength of the third sidewall 135, making the structure of the storage box 10 more compact.

[0060] In some embodiments, as shown in Figures 8 and 9, the first sidewall 130 has an outer sidewall 136 on the side away from the receiving cavity 101, and the second sidewall 230 has an inner sidewall 231 on the side close to the receiving cavity 101. The first mating portion 110 is provided on the outer sidewall 136, and the second mating portion 210 is provided on the inner sidewall 231.

[0061] In some embodiments, as shown in FIG1, the outer surface of the first cover 100 is provided with a first mark 140, and the outer surface of the second cover 200 is provided with a second mark 260. The position of the first mark 140 corresponds to the position of the first mating part 110, and the position of the second mark 260 corresponds to the position of the second mating part 210. The user can rotate the second cover 200 according to the first mark 140 and the second mark 260 on the outer surface of the storage box 10. When the first mark 140 and the second mark 260 are aligned, it indicates that the first mating part 110 and the second mating part 210 are also aligned.

[0062] In some embodiments, the first mark 140 may be provided on the first sidewall 130 of the first cover 100 as shown in FIG1, and the direction of the first mark 140 pointing to the first docking portion 110 is parallel to the direction of the rotation axis L, that is, the first mark 140 and the first docking portion 110 are aligned in the direction of the rotation axis L.

[0063] The second mark 260 can be disposed on the second sidewall 230 of the second cover 200, and the direction in which the second mark 260 points to the second mating portion 210 is parallel to the direction of the rotation axis L, that is, the second mark 260 and the second mating portion 210 are aligned in the direction of the rotation axis L. In some other embodiments, the first mark 140 and the first mating portion 110, and the second mark 260 and the second mating portion 21 may not be aligned axially, as long as the first mark 140 and the second mark 260 are aligned, the first mating portion 11 and the second mating portion 21 are also aligned.
