The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0052] On the one hand, this application provides a container cap, which is also a device for applying skin care products. A flexible sealing element is added to the outlet of the main body, and an opening structure is provided on the sealing element. When the cover is placed on the main body, it plays a corresponding abutting role against the ball of the contact part, thereby transmitting the squeezing force to the sealing element. The opening structure on the sealing element cannot be opened upward, so the skin care product is difficult to leak out.

[0053] Please refer to Figure 1 and Figure 2 This application provides a container cover 100, including a main body 10, a sealing element 20, a contact part 30, and a cover part 40.

[0054] The main body 10 is the main structure of the container cap 100, which plays a corresponding role in bearing and supporting; the cover 40 is placed on the main body 10 when not in use, which plays a preliminary role in preventing leakage; the contact part 30 is connected to the outlet 10b of the main body 10, which is used to achieve uniform and stable outward output of skin care products; the sealing element 20 plays a corresponding sealing role to reduce the probability of leakage of the container cap 100 when not in use.

[0055] Specifically, the main body 10 has an inlet 10a, an outlet 10b opposite to the inlet 10a, and a flow channel 10c that is connected to both the inlet 10a and the outlet 10b. Here, the inlet 10a is for skincare products to enter into the flow channel 10c of the main body 10; the flow channel 10c is for the flow of skincare products and serves a guiding function; and the outlet 10b is for the skincare products to flow out of the flow channel 10c, so as to achieve application to the user's skin surface.

[0056] The sealing element 20 is flexible and has an opening structure 20a. The sealing element 20 is placed on the main body 10 and covers the outlet 10b. Here, the overall shape of the sealing element 20 resembles a "cover," meaning it is open at one end and closed at the other. The open end of the sealing element 20 covers the outlet 10b to reduce the flow rate of skincare products directly from the outlet 10b. Furthermore, in use, the skincare products should flow out through the opening structure 20a. The position of the opening structure 20a on the sealing element 20 can be adjusted according to actual usage requirements. Of course, in other embodiments, the overall shape of the sealing element 20 can also be disc-shaped, plate-shaped, or irregularly shaped.

[0057] The contact portion 30 includes a housing 31 and a ball bearing 32 movably connected to the housing 31. The housing 31 covers the main body 10, and the ball bearing 32 is placed on the seal 20. Here, the housing 31 is used to limit the movement of the ball bearing 32, so that the ball bearing 32 is always movably connected to the housing 31, and during use, the ball bearing 32 is in direct contact with the user's skin.

[0058] The cover portion 40 is disposed on the main body portion 10 and abuts against the ball 32, so that the ball 32 abuts against the seal 20. Here, when the cover portion 40 is disposed on the main body portion 10, it will exert an abutting force on the ball 32, and then transmit the force to the seal 20 through the ball 32.

[0059] The cover portion 40 has a closed state and an open state. In the closed state, the cover portion 40 covers the main body portion 10 and abuts against the ball 32 so that the ball 32 contacts the seal 20 and the outlet 10b is sealed. In the open state, the cover portion 40 is separated from the main body portion 10 and the opening structure 20a connects the outlet 10b to the outside.

[0060] It should be noted that, in the open state, the opening structure 20a connects the outlet 10b to the outside in two ways: First, the seal 20 can elastically deform the ball 32 to open the opening structure 20a. Second, the opening structure 20a itself is always open; when the ball 32 is movable, the pressure inside the flow channel 10c can push the ball 32 up, thereby opening the opening structure 20a and allowing the skincare product to flow out.

[0061] In the first scenario, the opening structure 20a can be in the form of a slit or narrow slot. After the opening structure 20a is set, the surface material of the seal 20 is not removed. Therefore, in its natural state, the opening structure 20a is not open, and the seal 20 has a sealing effect on the outlet 10b. When compressed, the seal 20 undergoes elastic deformation, causing the opening structure 20a to enlarge and open.

[0062] Since the ball bearing 32 is capable of rolling relative to the outer casing 31, but when the ball bearing 32 is abutted by the cover portion 40, the ball bearing 32 cannot rotate, and at this time the ball bearing 32 is in contact with the seal 20. Thus, the seal 20 cannot elastically deform in the direction of the ball bearing 32, and the opening structure 20a cannot enlarge. Therefore, the seal 20 seals the outlet 10b. However, when the ball bearing 32 is unrestricted and can roll, it means that there is a movable gap between the ball bearing 32 and the seal 20. This movable gap allows the seal 20 to elastically deform when subjected to the squeezing force from the liquid storage container 50, thereby enlarging the opening structure 20a.

[0063] In the second scenario, the opening structure 20a can be formed by removing a portion of the material from the sealing member 20. In its natural state, the opening structure 20a is open. When the ball bearing 32 abuts against the sealing member 20, it seals the opening structure 20a, preventing the skincare product from leaking out. Alternatively, when the ball bearing 32 abuts against the sealing member 20, the sealing member 20 itself undergoes elastic deformation, closing the opening structure 20a. When the cover 40 is open and the liquid storage container 50 is squeezed, the pressure generated by squeezing the liquid storage container 50 acts on the sealing member 20, and this pressure can push the ball bearing 32 upwards, allowing the skincare product to flow out.

[0064] The opening structure 20a has two states: one is an open state when the cover 40 is removed from the main body 10 and no abutting force is applied to the ball 32; the other is a closed state when the cover 40 is placed on the main body 10 and an abutting force is applied to the ball 32. Here, the opening structure 20a of the seal 20 should always be in the open state, and only switch to the closed state when subjected to external force.

[0065] The container cap 100 provided by this utility model has a sealing member 20 added between the ball 32 of the contact part 30 and the main body part 10. The sealing member 20 covers the outlet 10b. When the cover part 40 covers the main body part 10, the cover part 40 can exert a squeezing force on the ball 32 and transmit this force to the sealing member 20, so that the sealing member 20 cannot deform in the direction of the ball 32. That is, the opening structure 20a cannot open in the direction of the ball 32, and liquid cannot flow out in the direction of the ball 32. In this way, the probability of leakage of the container cap 100 is reduced. At the same time, in the use state, the cover part 40 is removed from the main body part 10 to release the squeezing restriction on the ball 32, so that the sealing member 20 can elastically deform in the direction of the ball 32. When subjected to pressure, the opening structure 20a can be opened, so that the fluid skin care product can flow out of the opening structure 20a from the flow channel 10c and be evenly applied by the ball 32.

[0066] Please refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, the seal 20 has an open end 21, a closed end 22 and a side wall portion 23. The open end 21 is connected to the outlet 10b, the closed end 22 corresponds to the ball 32, and an opening structure 20a is provided on the closed end 22 and / or the side wall portion 23.

[0067] Specifically, the open end 21 is the end of the seal 20 that corresponds to the outlet 10b, the closed end 22 is the end that corresponds to the open end 21, and the side wall portion 23 is the circumferential portion of the seal 20 excluding the closed end 22. Therefore, the opening structure 20a can be provided on the closed end 22, on the side wall portion 23, or on both.

[0068] Thus, depending on actual usage requirements, the opening structure 20a can be selectively provided on the side wall portion 23 of the sealing member 20, or on the closed end 22 of the sealing member 20; or, the opening structure 20a can be provided on both the side wall portion 23 and the closed end 22.

[0069] Please refer to Figure 5 In some embodiments, the opening structure 20a includes a strip-shaped opening formed in the circumferential direction in the sidewall portion 23.

[0070] Specifically, the extension direction of the strip opening is the circumferential direction of the side wall portion 23. At the same time, the strip opening should only be formed on a part of the side wall portion 23. Thus, the side wall portion 23 is partially connected. When subjected to a compressive force along the axial direction of the seal 20, the strip opening is in a closed state.

[0071] Specifically, please refer to Figure 1 and Figure 5 The main body 10 is provided with a support column 14, which is hollow and has an outlet 10b at one end. A sealing element 20 is covered on the support column 14, and a strip-shaped opening is formed on the side wall 23.

[0072] Here, the support column 14 is the part of the main body 10 that protrudes outward, thereby providing corresponding support for the relatively soft sealing element 20.

[0073] Alternatively, please refer to Figure 6 In other embodiments, the opening structure 20a includes a cross-shaped opening formed on the closed end 22. Specifically, a cross-shaped opening refers to an opening with a "cross" shape.

[0074] Of course, in other embodiments, the opening structure 20a can also be in other shapes, such as T-shaped, V-shaped, etc.

[0075] Specifically, please refer to Figure 2 and Figure 6 The flow channel 10c is provided with a support column 15. One end of the support column 15 extends to the outside from the outlet 10b. The sealing element 20 is sleeved on the support column 15 and covers the outlet 10b. The closed end 22 is spaced apart from the support column 15 and has a cross opening.

[0076] Here, the support column 15 should be solid, and the position of the support column 15 should correspond to and be spaced apart from the cross opening. That is, the support column 15 can play a corresponding positioning and limiting role. At the same time, when the closed end 22 of the seal 20 is subjected to a compressive force, the closed end 22 just abuts against one end of the support column 15. At this time, the cross opening is in a closed state. After the compressive force is removed, the closed end 22 separates from the support column 15 to form a certain gap. At this time, the cross opening is in an open state.

[0077] Please refer to Figures 1 to 6In some embodiments, the outer shell 31 is provided with a groove 31a and a connecting hole 31b that penetrates the groove wall of the groove 31a. The groove 31a is provided for the ball 32 to rotate. The side wall portion 23 is located in the connecting hole 31b. The open end 21 is disposed away from the groove 31a. The open end 21 is also provided with a limiting flange 24. The limiting flange 24 is clamped between the outer shell 31 and the main body portion 10.

[0078] Specifically, the ball bearing 32 should be rotatably disposed in the groove 31a of the housing 31 and exposed to the outside through the connection hole 31b, so that the ball bearing 32 can be housed in the housing 32 without falling off, and can also abut against the closed end 22 of the seal 20. At the same time, the housing 31 and the main body 10 also clamp the limiting flange 24 of the seal 20 to further limit and fix the seal 20.

[0079] For details, please refer to Figure 3 and Figure 4 The outer casing 31 includes a first casing 311 and a second casing 312 that cover each other. Meanwhile, a groove 31a is provided in the first casing 311 and / or the second casing 312 to meet the requirements of the ball bearing 32 for accommodation and rotation. In addition, the first casing 311 and the second casing 312 are also provided with a through connection hole 31b, so that the ball bearing 32 can extend to the outside to contact the user's skin and abut against the closed end 22 of the seal 20.

[0080] Please refer to Figures 1 to 4 In some embodiments, the main body 10 includes a support 11 and a first connecting plate 12 and a second connecting plate 13 stacked on top of each other. The flow channel 10c includes a first branch structure 10c1 formed in the support 11 and a second branch structure 10c2 formed in the first connecting plate 12 and the second connecting plate 13. The support 11 has an inlet 10a that communicates with the first branch structure 10c1. The first connecting plate 12 has an outlet 10b that communicates with the second branch structure 10c2. The second connecting plate 13 has a through hole 13a through which the first branch structure 10c1 communicates with the second branch structure 10c2.

[0081] Specifically, the bracket 11 is the main body of the main body 10, which plays a role in bearing and supporting. At the same time, the bracket 11 is also the main part that connects with the skin care kit. For example, the bracket 11 is provided with internal threads, and the skin care kit is provided with matching external threads.

[0082] The second branch structure 10c2 should be formed by machining the opposite end faces of the two connecting plates. For example, a groove structure can be opened only on the second connecting plate 13. After it covers the first connecting plate 12, the groove structure and the inner wall of the first connecting plate 12 enclose the second branch structure 10c2. Alternatively, a groove structure can be opened only on the first connecting plate 12, or a groove structure can be opened on both the first connecting plate 12 and the second connecting plate 13.

[0083] The first connecting plate 12 and the second connecting plate 13 can be connected by welding. That is, when both are made of plastic, the first connecting plate 12 and the second connecting plate 13 can be fixedly connected by heat fusion, that is, a heat fusion layer is formed between the two. Alternatively, they can be connected by plugging. That is, a mounting post is provided on one of them, and a mounting hole adapted to the mounting post is opened on the other.

[0084] Thus, the fluid skincare product flows from the inlet 10a into the first branch structure 10c1, then enters the second branch structure 10c2 through the through hole 13a, and finally flows out from the outlet 10b onto the roller ball 32, where it is evenly applied to the user's skin surface.

[0085] Please refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, a support column 14 is provided on the side of the first connecting plate 12 away from the second connecting plate 13, an outlet 10b is formed on the support column 14, a sealing member 20 is covered on the support column 14, and a strip-shaped opening is formed on the side wall portion 23.

[0086] Specifically, the support column 14 is the outward protrusion of the first connecting plate 12, thereby providing corresponding support for the relatively soft sealing element 20. In this way, when the side wall portion 23 of the sealing element 20 is fitted onto the support column 14, the strip opening is in an open state, and when the closed end 22 of the sealing element 20 is subjected to a compressive force, the strip opening is in a closed state.

[0087] Alternatively, please refer to Figure 2 , Figure 4 and Figure 6 In other embodiments, the second connecting plate 13 is provided with a support column 15, which is placed inside the second branch structure 10c2 and extends to the outside from the outlet 10b. The sealing member 20 is covered on the support column, and a cross opening is formed on the closed end 22.

[0088] Specifically, the support column 15 should be solid, and the position of the support column 15 should correspond to the cross opening. That is, the support column 15 can play a corresponding positioning and limiting role. At the same time, when the closed end 22 of the seal 20 is subjected to a compressive force, the closed end 22 is exactly abutted against the end of the support column 15 away from the second connecting plate 13. At this time, the cross opening is in a closed state. After the compressive force is removed, the closed part separates from the support column 15 to form a certain gap. At this time, the cross opening is in an open state.

[0089] Thus, the support column 14 is used to position and fix the seal 20 so that the strip opening of the seal 20 is closed when it is subjected to compressive force in its axial direction; or, the support column 15 can be used to position and limit the seal 20 so that the cross opening of the seal 20 is closed when it is subjected to compressive force in its axial direction.

[0090] Please refer to Figure 7 and Figure 8 In some embodiments, the first connecting plate 12 and the second connecting plate 13 are installed between the housing 31 and the bracket 11, and the first connecting plate 12 and the second connecting plate 13 are sealed and fixedly connected.

[0091] Furthermore, when the first connecting plate 12 and the second connecting plate 13 are made of plastic, they can be fixedly connected by heat fusion. In one embodiment, the bottom wall of the outer shell 31 is pressed against the first connecting plate 12, and the second connecting plate 13 is pressed against the upper end of the bracket 11. The first connecting plate 12 and the second connecting plate 13 are further positioned and fixed by the joint clamping of the bracket 11 and the outer shell 31.

[0092] In some embodiments, a first annular protrusion 16 is provided on one of the first connecting plate 12 and the second connecting plate 13, and the first connecting plate 12 is thermally connected to the second connecting plate 13 through the first annular protrusion 16.

[0093] Specifically, a second branch structure 10c2 is formed between the two connecting plates. The connection between the two should be sealed to a certain extent. Therefore, when both connecting plates are made of plastic, a first annular protrusion 16 can be formed to meet the corresponding hot melt connection requirements.

[0094] Alternatively, please refer to Figure 9 and Figure 10 In other embodiments, one of the first connecting plate 12 and the second connecting plate 13 is provided with a first annular protrusion 16, and the other of the first connecting plate 12 and the second connecting plate 13 is provided with an annular groove 17. The first annular protrusion 16 and the annular groove 17 are adapted to each other so that the first connecting plate 12 and the second connecting plate 13 are sealed together.

[0095] Specifically, the sealing at the connection between the two connecting plates can be increased by forming a convex-concave fit between the first annular protrusion 16 and the annular groove 17.

[0096] Thus, the first annular protrusion 16 is used to achieve a sealed connection between the first connecting plate 12 and the second connecting plate 13; or, the first annular protrusion 16 can be adapted to the annular groove 17 to improve the sealing performance at the connection between the two.

[0097] Please refer to Figure 7 In some embodiments, the first connecting plate 12 is provided with a second annular protrusion 18 on the side opposite to the second connecting plate 13, and the outer shell 31 is thermally fused to the first connecting plate 12 through the second annular protrusion 18.

[0098] Specifically, the outer shell 31 and the first connecting plate 12 are made of the same or similar materials, that is, a heat-fused connection can be formed between the two by the second annular protrusion 18.

[0099] Alternatively, please refer to Figure 2 and Figure 4 In some embodiments, the outer casing 31 is snap-fitted to the second connecting plate 13.

[0100] Specifically, multiple buckles 313 are provided on the bottom wall of the second housing 312. The bottom wall of the second housing 312 is pressed against the first connecting plate 12 and then snapped onto the edge of the second connecting plate 13 by the buckles 313, thereby securing the first connecting plate 12 and the second connecting plate 13 within the installation space formed by the second housing 312 and the buckles 313. This can further increase the installation stability of the first connecting plate 12 and the second connecting plate 13.

[0101] Thus, the outer casing 31 can be connected to the connecting plate via the second annular protrusion 18; or, the outer casing 31 can also be snapped to the connecting plate via a corresponding snap-fit ​​structure.

[0102] Please refer to Figure 1 and Figure 2 In some embodiments, a limiting post 41 is provided on the inner wall of the cover portion 40, and the limiting post 41 abuts against the ball 32.

[0103] Specifically, by utilizing the limiting tube protruding from the inner wall of the cover portion 40, when the cover portion 40 is placed on the main body portion 10, the limiting tube abuts against the ball 32, so that the ball 32 applies a squeezing force to the seal 20, thereby keeping the opening structure 20a in a closed state.

[0104] On the other hand, such as Figures 11 to 18This application provides a skincare kit, including a liquid storage container 50, a container cap 100, a first anti-rotation device, and a second anti-rotation device. The liquid storage container 50 has a liquid outlet 51a. The container cap 100 is detachably connected to the liquid storage container 50 and is used to cover the liquid outlet 51a. The first anti-rotation device includes a first anti-rotation part 53 disposed on the liquid storage container 50 and a second anti-rotation part 11b disposed on the container cap 100. The second anti-rotation device includes a third anti-rotation part 54 disposed on the liquid storage container 50 and a fourth anti-rotation part 19 disposed on the container cap 100. The first anti-rotation part 53 and the third anti-rotation part 54 are distributed on two different imaginary circles, the two imaginary circles are concentric and their centers are located on the center line of the liquid outlet 51a. The first anti-rotation part 53 cooperates with the second anti-rotation part 11b, and the third anti-rotation part 54 cooperates with the fourth anti-rotation part 19 to jointly restrict the container cap 100 from rotating relative to the liquid storage container 50.

[0105] The imaginary circle includes a first imaginary circle R1 and a second imaginary circle R2 with different radii. The two are concentric circles. The radius of the first imaginary circle R1 is smaller than the radius of the second imaginary circle R2. The first anti-rotation part 53 and the second anti-rotation part 11b are distributed on the first imaginary circle R1, and the third anti-rotation part 54 and the fourth anti-rotation part 19 are distributed on the second imaginary circle R2.

[0106] In some embodiments, the container cap 100 is used to cover the liquid storage container 50. When the two are connected, the second anti-rotation part 11b on the container cap 100 blocks the first anti-rotation part 53 on the liquid storage container 50, and the fourth anti-rotation part 19 blocks the third anti-rotation part 54. At this time, if the container cap 100 has a tendency to rotate relative to the liquid storage container 50, the second anti-rotation part 11b and the fourth anti-rotation part 19 cannot continue to move due to the blocking of the first anti-rotation part 53 and the third anti-rotation part 54, thereby limiting the rotation of the container cap 100 relative to the liquid storage container 50. This arrangement, through the joint action of two anti-collision devices at different positions, can generate a greater force to prevent the relative rotation between the container cap 100 and the liquid storage container 50, further reducing the relative movement between the container cap 100 and the liquid storage container 50, thereby improving the closing performance of the container cap 100.

[0107] In some embodiments, the first anti-rotation part 53 is a notch, and the second anti-rotation part 11b is a protrusion that is inserted into the first anti-rotation part 53; in some embodiments, the third anti-rotation part 54 is a notch, and the fourth anti-rotation part 19 is a protrusion that is inserted into the third anti-rotation part 54.

[0108] The two embodiments described above can be configured together or one can be configured separately. When configured together, the limiting effect on the container lid 100 is the greatest.

[0109] Specifically, in this embodiment, both the first anti-rotation part 53 and the third anti-rotation part 54 are configured as notches, and both the second anti-rotation part 11b and the fourth anti-rotation part 19 are configured as protrusions for insertion. When the container cap 100 is closed onto the liquid storage container 50, the protrusions are inserted into the notches. If the container cap 100 still has a tendency to rotate, the protrusions will abut against the sidewall of the notch. The sidewall of the notch can restrict the movement of the protrusions. This arrangement can restrict the relative rotation of the container cap 100 and the liquid storage container 50. In some other embodiments, the second anti-rotation part 11b is a notch, the first anti-rotation part 53 is a protrusion that inserts into the second anti-rotation part 11b, the fourth anti-rotation part 19 is a notch, and the third anti-rotation part 54 is a protrusion that inserts into the fourth anti-rotation part 19.

[0110] In another embodiment, the first anti-rotation part 53 is a protrusion, the second anti-rotation part 11b is a protrusion that abuts against the first anti-rotation part 53, the third anti-rotation part 54 is a protrusion, and the fourth anti-rotation part 19 is a protrusion that abuts against the third anti-rotation part 54.

[0111] In some embodiments, the liquid storage container 50 is provided with a guide protrusion 53b and a blocking protrusion 53a, which are distributed circumferentially along an imaginary circle. The gap between the guide protrusion 53b and the blocking protrusion 53a constitutes a first anti-rotation portion 53. The height of the guide protrusion 53b protruding radially outward along the imaginary circle is less than the height of the blocking protrusion 53a protruding radially outward along the imaginary circle.

[0112] Specifically, the outer edge of the guide protrusion 53b is arc-shaped, and the height of the guide protrusion 53b protruding radially in the imaginary circle is d1, while the height of the blocking protrusion 53a protruding is d2. In this embodiment, d1 is less than d2, and a gap is formed between the guide protrusion 53b and the blocking protrusion 53a. When the container cap 100 closes the liquid storage container 50, the second anti-rotation part 11b gradually approaches the guide protrusion 53b by rotating the container cap 100. The guide protrusion 53b is made of flexible material and can deform to a certain extent when subjected to pressure. Under the action of external force, the second anti-rotation part 11b will abut against the outer edge of the guide protrusion 53b and slide along the edge of the guide protrusion 53b. The second anti-rotation part 11b moves until it falls into the notch. If the container cap 100 still has a tendency to rotate, the second anti-rotation part 11b will abut against the end face of the blocking protrusion 53a. Since the blocking protrusion 53a protrudes at a high height, the second anti-rotation part 11b cannot continue to move towards the blocking protrusion 53a. This arrangement restricts the rotation of both the container cap 100 and the liquid storage container 50. During the sliding process of the second anti-rotation part 11b against the guide protrusion 53b, the second anti-rotation part 11b can be clearly felt to decelerate due to the reaction force. The user can also clearly perceive from this feedback that the second anti-rotation part 11b is about to fall into the first anti-rotation part 53. In some other embodiments, the first anti-rotation part 53 is configured as a limiting groove on the end face of the liquid storage container 50. The bottom wall of the limiting groove is an inclined arc surface. When the second anti-rotation part 11b enters the limiting groove, the second anti-rotation part 11b can fall into the deepest part of the limiting groove.

[0113] Furthermore, both the guide protrusion 53b and the blocking protrusion 53a are provided in two pieces, thus forming two first anti-rotation parts 53. The two first anti-rotation parts 53 are respectively located on opposite sides of the center of the imaginary circle. Correspondingly, two second anti-rotation parts 11b are provided inside the container cover 100. The first anti-rotation parts 53 and the second anti-rotation parts 11b are arranged in a one-to-one correspondence. This arrangement can further increase the limiting force and play a better anti-rotation role for the container cover 100 and the liquid storage container 50.

[0114] In some embodiments, the liquid storage container 50 includes a container body 51 and a connecting portion 52. The container body 51 has a first surface, and the first surface is provided with a positioning boss 55. The connecting portion 52 is located on the positioning boss 55 and is provided with a liquid outlet 51a. The positioning boss 55 is provided with a notch on its periphery to form a third anti-rotation portion 54.

[0115] Specifically, the top surface of the container body 51 is a first surface, and a positioning boss 55 is provided on the first surface. The outer periphery of the positioning boss 55 is close to the outer periphery of the container body 51. The third anti-rotation part 54 is a notch provided on the outer periphery of the positioning boss 55. When the container cap 100 closes the liquid storage container 50, the fourth anti-rotation part 19 on the container cap 100 will fall into the notch and be limited by the side wall of the notch. This arrangement is to limit the rotation of the container cap 100 relative to the liquid storage container 50. In some other embodiments, the upper surface of the positioning boss 55 is provided with a limiting groove to form the third anti-rotation part 54, and the fourth anti-rotation part 19 is inserted into the limiting groove to achieve the anti-rotation function.

[0116] In some embodiments, the container cap 100 has a mounting groove 11c, the side wall of the mounting groove 11c is provided with a fourth anti-rotation part 19, and the periphery of the positioning boss 55 is adapted to and in contact with the side wall of the mounting groove 11c.

[0117] Specifically, the bottom of the container cap 100 is recessed with a mounting groove 11c. The side wall of the mounting groove 11c is provided with a fourth anti-rotation part 19. When the container cap 100 closes the liquid storage container 50, the side wall of the mounting groove 11c can abut against the outer peripheral wall of the positioning boss 55 to enhance the support of the container cap 100. The fourth anti-rotation part 19 will fall into the third anti-rotation part 54 to achieve the anti-rotation function. With this arrangement, the positioning boss 55 plays a positioning role, so that the container cap 100 is not easy to shake after installation. The mounting groove 11c can cover the upper end of the liquid storage container 50. In this embodiment, the mounting groove 11c is located inside the bracket 11, and the fourth anti-rotation part 19 protrudes from the inner side wall of the bracket 11.

[0118] In some embodiments, the container cap 100 is provided with an annular sleeve 11a, the inner side of the annular sleeve 11a is provided with an internal thread, the liquid storage container 50 is provided with an external thread that mates with the internal thread and surrounds the liquid outlet 51a, and both the internal thread and the external thread are double-threaded; the second anti-rotation part 11b is provided on the annular sleeve 11a.

[0119] Specifically, in this embodiment, a connecting part 52 protrudes from the center of the positioning boss 55. The connecting part 52 has a liquid outlet 51a. The connecting part 52 is cylindrical. The annular sleeve 11a is located at the center of the mounting groove 11c, and the height of the annular sleeve 11a does not protrude beyond the bottom surface of the container cap 100. The annular sleeve 11a is adapted to the connecting part 52. The annular sleeve 11a has an internal thread, and correspondingly, an external thread is provided on the outer peripheral wall of the connecting part 52. The connecting part 52 can be screwed onto the annular sleeve 11a. A second anti-rotation part 11b is provided on the bottom wall of the annular sleeve 11a. When the connecting part 52 is fully screwed onto the annular sleeve 11a, the second anti-rotation part 11b can fall within the first anti-rotation part 53 of the connecting part 52. In embodiments without a first anti-rotation device, threaded connections may experience thread wear and failure after prolonged use. However, in this embodiment, once the threaded connection is in place, the first anti-rotation part 53 and the second anti-rotation part 11b abut against each other, preventing the container cap 100 from rotating further. This design mitigates the thread failure problem and ensures the container cap 100 is not easily detached from the liquid storage container 50. Furthermore, both the internal and external threads are double-threaded, allowing the container cap 100 to be tightened with the connecting part 52 in different positions, improving the user experience. Additionally, the second anti-rotation part 11b at the bottom wall of the annular sleeve 11a enhances its structural strength. In other embodiments, the connecting part 52 is movably inserted into the annular sleeve 11a. The side wall of the annular sleeve 11a is provided with a magnetic attractant, and a corresponding magnetic attractant is provided on the side wall of the connecting part 52. When the connecting part 52 is inserted into the annular sleeve 11a, the magnetic attractants on both sides attract each other to increase installation stability.

[0120] Furthermore, the guide protrusion 53b and the blocking protrusion 53a are located at the bottom of the connecting part 52 and below the external thread. Similarly, the second anti-rotation part 11b, which is provided on the bottom wall of the annular sleeve 11a, protrudes out of the annular sleeve 11a, so that after the threaded connection is completed, the second anti-rotation part 11b falls into the first anti-rotation part 53.

[0121] In some embodiments, four third anti-rotation parts 54 are provided, the four third anti-rotation parts 54 are located on the same imaginary circle, and two of the third anti-rotation parts 54 are located in the same radial direction, while the other two third anti-rotation parts 54 are located in another radial direction; two fourth anti-rotation parts 19 are provided, and the two fourth anti-rotation parts 19 correspond to and cooperate with any two third anti-rotation parts 54 located in the same radial direction.

[0122] Specifically, four third anti-rotation portions 54 are distributed on the second imaginary circle R2. Two third anti-rotation portions 54 are distributed on each of the two radial directions of the imaginary circle, and two fourth anti-rotation portions 19 are provided. When the container cap 100 is installed on the liquid storage container 50, the two fourth anti-rotation portions 19 will respectively engage with the two third anti-rotation portions 54 located on the same radial direction of the imaginary circle. This arrangement can increase the restraining force of the second anti-rotation device and further prevent the container cap 100 from rotating relative to the liquid storage container 50. In some other embodiments,

[0123] In some embodiments, two third anti-rotation portions 54 on the same radial direction are symmetrically arranged with reference to the center of an imaginary circle. Each third anti-rotation portion 54 is provided with at least a connected guide wall 54b and a blocking wall 54a. The fourth anti-rotation portion 19 is introduced into the third anti-rotation portion 54 by the guide wall 54b and abuts against the blocking wall 54a.

[0124] Specifically, two third anti-rotation parts 54 located in the same radial direction are symmetrically arranged with the center of the circle as the reference, and two fourth anti-rotation parts 19 are also symmetrically arranged with the center of the circle as the reference. The third anti-rotation part 54 is configured as a triangular notch recessed towards the inner side of the imaginary circle. The two adjacent sides of the triangular notch are the guide wall 54b and the blocking wall 54a, respectively. The guide wall 54b and the blocking wall 54a have different lengths. When the container cap 100 is about to complete the threaded connection, the fourth anti-rotation part 19 will move towards the guide wall 54b and abut against the guide wall 54b, and continue to move along the guide wall 54b until it stops at the blocking wall 54a. Since the shape of the fourth anti-rotation part 19 is adapted to the triangular notch, when the fourth anti-rotation part 19 falls completely into the notch, it can be locked in place. Furthermore, due to the symmetrical arrangement, a fourth anti-rotation part 19 can only be locked into the third anti-rotation part 54 with the appropriate shape, and the fourth anti-rotation part 19 will not be embedded in the wrong third anti-rotation part 54. This design makes the connection between the third anti-rotation part 54 and the fourth anti-rotation part 19 more stable and less likely to detach, thereby further preventing the container cap 100 from rotating relative to the liquid storage container 50.

[0125] In some embodiments, the first anti-rotation device and the second anti-rotation device are distributed in different radial directions of the imaginary circle.

[0126] Specifically, the first anti-rotation device is disposed on the diameter of the first imaginary circle R1, and the second anti-rotation device is disposed on the diameter of the second imaginary circle R2. These two diameters are staggered at a certain angle. In this embodiment, the first anti-rotation part 53 and the second anti-rotation part 11b are distributed in the left-right direction of the imaginary circle, and the third anti-rotation part 54 and the fourth anti-rotation part 19 are distributed in the up-down direction of the imaginary circle. These four parts together restrict the rotational freedom of the container cap 100, further preventing the container cap 100 from rotating relative to the liquid storage container 50. In other embodiments, the first and second anti-rotation devices are distributed in the same radial direction of the imaginary circle.
