With the improvement of people's living standards, people pay more and more attention to their personal image, and the frequency and scope of cosmetics use are getting wider and wider. Generally, cosmetics are placed in cosmetic bottles.

[0003] Chinese utility model patent CN218520199U discloses a cosmetic bottle cap anti-loosening structure, which includes a bottle body, a threaded interface fixedly connected to the bottle body opening, and a cover body threadedly connected to the outer wall of the threaded interface. The inner wall of the threaded interface is provided with a plurality of limit grooves extending along its axial direction, and the plurality of limit grooves are evenly arranged around the threaded interface in the circumferential direction. The cover body is provided with a plurality of limit rods clamped in the limit grooves, and the cover body is also provided with a control mechanism for driving the limit rods to disengage from the limit grooves.

[0004] However, when using a cosmetic bottle having this structure, part of the cosmetics may be easily stuck in the limiting grooves circumferentially arranged on the inner wall of the threaded structure, resulting in waste of cosmetics. Utility Model Content

[0005] The purpose of the utility model is to provide a bottle cap with an anti-loosening structure in view of the above-mentioned technical problems, so as to achieve the effect of reducing the waste of cosmetics caused by the anti-loosening structure.

[0006] In view of this, the utility model provides a bottle cap with an anti-loosening structure, which is characterized by comprising:

[0007] A bottle body, wherein a threaded interface is arranged on the top of the bottle body, and an inner cover is threadedly arranged on the threaded interface;

[0008] An outer cover, which is movably sleeved on the outer side of the inner cover and is slidably connected to the inner cover;

[0009] The anti-loosening structure is evenly distributed between the outer cover and the inner cover in the circumferential direction, and is used to drive the inner cover to rotate when the outer cover is rotated. The anti-loosening structure includes:

[0010] The driving part is evenly distributed between the outer cover and the inner cover in the circumferential direction to transmit power.

[0011] An elastic member, which is disposed between the outer cover and the inner cover and is used to separate the driving part so that the outer cover can rotate outside the inner cover;

[0012] A sealing structure is provided between the threaded interface and the inner cover to seal the bottle body.

[0013] In the technical solution, when the cosmetic bottle is not in use, the outer cover and the inner cover are connected by sliding, so that the friction between the cosmetic bottle and other objects can only drive the outer cover to rotate, which is conducive to reducing the phenomenon of cosmetics leaking out due to the loosening of the inner cover. When the cosmetic bottle needs to be opened, the outer cover and the inner cover can be connected by the driving part, so that the inner cover can be driven to rotate when the outer cover is rotated, thereby unscrewing the inner cover from the threaded interface. The driving part can be reset by the elastic member, so that the outer cover can be rotated outside the inner cover, which is conducive to reducing the phenomenon of the inner cover loosening from the spiral interface. The sealing structure provided can improve the sealing of the cosmetic bottle and reduce the waste of cosmetics caused by the anti-loosening structure.

[0014] In the above technical solution, further, the sealing structure includes:

[0015] An inclined surface, the inclined surface is provided at the top end of the inner wall of the threaded interface;

[0016] A sealing ring, which is fixedly arranged on the top surface of the inner cover and is arranged in a trapezoidal shape;

[0017] Wherein, the sealing ring bevel is arranged opposite to the inclined surface, and the sealing ring bevel is pressed against the inclined surface.

[0018] In the present technical solution, when the inner cover is screwed into the threaded interface, the sealing ring is guided and pressurized by the inclined surface, so that the inclined edge of the sealing ring fits evenly on the inclined surface, thereby effectively closing the gap between the threaded interface and the inner cover, which helps to prevent cosmetics from leaking out of the gap between the threaded interface and the inner cover.

[0019] In the above technical solution, further, the driving unit includes:

[0020] The card slots are evenly distributed around the center of the inner cover and are provided at least at two locations;

[0021] A card block, which is arranged on the top surface in a circumferential direction based on the center of the outer cover, and the number of the card blocks is consistent with the card slot;

[0022] Wherein, the block and the slide slot are connected in a sliding manner.

[0023] In this technical solution, by pushing the outer cover downward, the block disposed inside the outer cover can be inserted into the slot, and the inner cover and the threaded interface can be tightened or unscrewed through the cooperation between the block and the slot. The elastic member can separate the slot and the block when no pressure is applied to the outer cover, so that the outer cover can rotate outside the inner cover, which is conducive to reducing the phenomenon of the inner cover loosening from the spiral interface.

[0024] In the above technical solution, further, the elastic member includes:

[0025] A top plate, the top plate is arranged on the top of the inner cover, and a guide rod is fixedly arranged at the center of the top plate;

[0026] A guide tube, the guide tube is fixedly arranged on the top surface of the outer cover and is slidably connected to the guide rod;

[0027] The fixing seats are evenly distributed in the circumferential direction between the top surface of the outer cover and the top surface of the top plate, and are symmetrically arranged;

[0028] Wherein, a spring is arranged in the fixing seat.

[0029] In this technical solution, the distance between the movable plate and the inner cover is controlled by the pressure of the spring, thereby controlling the engagement and separation of the card block and the card slot. When the outer cover is pushed downward, the distance between the spring, the guide rod and the guide tube is compressed, and the inner cover is driven to rotate through the driving part (card block and card slot) to achieve the tightening or unscrewing of the threaded interface. When there is no thrust acting on the outer cover, the distance between the spring, the guide rod and the guide tube is extended, so that the card block is disengaged from the card slot, allowing the outer cover to rotate outside the inner cover without driving the inner cover to rotate.

[0030] In the above technical solution, further, marks are provided on the outer walls of the outer cover and the inner cover, and the positions of the marks are corresponding to the positions of the card blocks and the card slots.

[0031] In the technical solution, the provided mark can facilitate the user to align the card block with the card slot, which is beneficial to improving the efficiency of opening the cosmetic bottle.

[0032] In the above technical solution, further, chamfers are provided on both sides of the top of the slot.

[0033] In the above technical solution, further, anti-slip patterns are provided on the outer wall of the outer cover.

[0034] In this technical solution, the anti-slip pattern can increase the friction coefficient of the outer cover, making it easier to hold and improving the efficiency of opening the cosmetic bottle.

[0035] The beneficial effects of the utility model are:

[0036] 1. The outer cover and the inner cover can be connected by the driving part, so that the inner cover can be driven to rotate when the outer cover is rotated, thereby unscrewing the inner cover from the threaded interface. The driving part can be reset by the elastic member provided, so that the outer cover can be rotated outside the inner cover, which is helpful to reduce the phenomenon of the inner cover loosening from the spiral interface.

[0037] 2. When the inner cover is screwed into the threaded interface, the sealing ring is guided and pressed by the inclined surface, so that the inclined edge of the sealing ring fits evenly on the inclined surface, thereby effectively closing the gap between the threaded interface and the inner cover, which helps to prevent cosmetics from leaking out of the gap between the threaded interface and the inner cover.
