For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0034] like Figures 1-6 As shown, in the first aspect, the embodiment of the present application proposes a bottle cap, including an annular cover body 1, the annular cover body 1 includes a sealing portion 11, a connecting portion 12 connected to the lower end surface of the sealing portion 11, the connecting portion 12 is used to be threadedly connected to the outer wall of the open end 41 of the bottle body 4, and the sealing portion 11 is used to cover the open end 41 of the bottle body 4 and seal the open end 41; an abutment 2 is provided at one end of the connecting portion 12 away from the sealing portion 11, and the abutment 2 is provided with one or more, such as Figure 5As shown, a plurality of abutment members 2 are arranged at intervals along the circumference of the connecting portion 12, and a sliding cavity for accommodating the abutment members 2 is provided along the radial direction of the connecting portion 12. The abutment members 2 are slidably assembled in the sliding cavity, and an elastic member for driving the abutment members 2 to slide along the radial direction of the connecting portion 12 is provided between the abutment members 2 and the sliding cavity; an abutment portion 21 and a pressure-bearing portion 22 are provided along the length direction of the abutment member 2, and the abutment portion 21 is used to abut against the outer wall of the opening end 41. The abutment portion 21 in this scheme can be made of a material with a certain elasticity, and when it is subjected to pressure, it will produce a certain degree of deformation; in the initial state, the abutment portion 21 does not protrude from the inner wall of the connecting portion 12 and is positioned In the connecting portion 12, the pressure-bearing portion 22 at least partially extends outward from the connecting portion 12, and the side of the pressure-bearing portion 22 away from the abutting portion 21 has an inclined surface 221 extending in a direction away from the abutting portion 21 and inclined from top to bottom; and the driving ring 3 is located above the inclined surface 221, and the driving ring 3 is coaxially fitted on the outer wall of the connecting portion 12 and can move axially along the connecting portion 12; the driving ring 3 is driven to move axially along the connecting portion 12, so that the lower end surface of the driving ring 2 abuts on the inclined surface 221, thereby driving the abutting member 2 to slide toward the inside of the annular cover body 1, and making the abutting portion 21 abut on the outer wall of the open end 41 of the bottle body 4.

[0035] During the specific implementation, the annular cover body 1 is screwed onto the open end 41 of the bottle body 4 and is threadedly connected between the open end 41 of the bottle body 4, so that the sealing portion 11 abuts against the upper end surface of the open end 41 of the bottle body 4, for achieving sealing of the opening on the open end 41 of the bottle body 4; then the driving ring 3 is controlled to move downward along the axial direction of the connecting portion 12 toward the direction close to the inclined surface 221, so that the lower end surface of the driving ring 3 abuts against the inclined surface 221, and the driving ring 3 is continued to be controlled to move downward. In the subsequent process, through the cooperation between the lower end surface of the driving ring 3 and the inclined surface 221, the multiple abutting members 2 are forced to move simultaneously in the connecting portion 12 toward the axial direction close to the connecting portion 12 (the elastic member does not move in this process). The bottle cap 41 is squeezed and compressed, and the bottle cap 42 is squeezed and compressed. ...

[0036] When the bottle cap needs to be removed, the driving ring 3 is first moved upward so that the inner wall of the driving ring 3 no longer contacts the pressure portion 22 of the abutment 2. At this time, the abutment 2 moves axially away from the connecting portion 12 along the radial direction of the connecting portion 12 under the action of the elastic member, so that the pressure portion 22 extends out of the connecting portion 12 again, and then the annular cover body 1 is screwed.

[0037] In some embodiments of the present application, Figure 2 As shown, an annular groove 211 is provided coaxially with the annular cover body 1 on the outer peripheral wall of the connecting portion 12, and the driving ring 3 is threadedly assembled in the annular groove 211. A first threaded portion 212 is provided at the upper end of the annular groove 211, and a second threaded portion 31 is provided at the upper end of the inner wall of the driving ring 3, so that the driving ring 3 is threadedly assembled in the annular groove 211. When the driving ring 3 is set, the outer wall of the driving ring 3 is kept flush with the outer wall of the connecting portion 12 (to ensure the overall aesthetics of the annular cover body 1), and the pressure-bearing portion 22 is at least partially placed in the annular groove 211; Figure 3 、 Figure 4 As shown, in this embodiment, the abutment 2 is arranged in contact with the bottom wall of the annular groove 211, and can also be arranged at an interval above the bottom wall of the annular groove 211. After the annular cover 1 is assembled on the open end 41 of the bottle body 4, the driving ring 3 is screwed and moved from top to bottom in the annular groove 211, so that the lower end surface of the driving ring 3 is pressed against the inclined surface 221 of the pressure-receiving portion 22, thereby forcing the pressure-receiving portion 22 to shrink from the annular groove 211 to the connecting portion 12, and simultaneously driving the abutment 2 1 moves toward the open end 41, so that the abutting portion 21 abuts the outer wall of the open end 41; when the driving ring 3 completely passes over the pressure-receiving portion 22, the pressure-receiving portion 22 is completely retracted into the connecting portion 12, and the abutting portion 21 at the other end is now tightly abutted against the outer wall of the open end 41 of the bottle body 4 (the abutting portion 21 undergoes a certain degree of extrusion deformation), thereby increasing the frictional resistance between the annular cover 1 and the open end 41 of the bottle body 4, helping to reduce the probability of the annular cover 1 becoming loose when the bottle body 4 is shaken. In this embodiment, the arrangement of the first threaded portion 212 and the second threaded portion 31 should satisfy the following requirements: when the lower end surface of the driving ring 3 completely passes over the pressure-receiving portion 22, the first threaded portion 212 and the second threaded portion 31 do not disengage.

[0038] In some embodiments of the present application, Figure 6As shown, the abutment 2 also includes a connecting rod 23 connected between the pressure-bearing part 22 and the abutment 21, and the width of the connecting rod 23 is smaller than the width of both the pressure-bearing part 22 and the width of the abutment 21; the sliding cavity includes a first accommodating cavity 121, a sliding groove 24, and a second accommodating cavity 122 which are sequentially connected from the axial end away from the connecting part 12 to the axial end close to the connecting part 12, the pressure-bearing part 22 is slidably assembled in the first accommodating cavity 121, the connecting rod 23 is slidably assembled in the sliding groove 24, and the abutment 21 is slidably assembled in the second accommodating cavity 122, and the end of the connecting rod 23 connected to the pressure-bearing part 22 is at least partially located in the first accommodating cavity 121, and an elastic member is connected between the pressure-bearing part 22 and the first accommodating cavity 121 and / or the abutment 21 and the second accommodating cavity 122, and the elastic member is a spring.

[0039] When the lower end face of the driving ring 3 does not contact the inclined surface 221 on the pressure-receiving part 22, under the action of the spring, a part of the pressure-receiving part 22 is located in the first accommodating cavity 121, and the other part extends outward from the first accommodating cavity 121 and is placed in the annular groove 211, while the abutting part 21 is located in the second accommodating cavity 122. When the inclined surface 221 on the pressure-receiving part 22 is squeezed by the lower end face of the driving ring 3, the pressure-receiving part 22 is forced to shrink from the annular groove 211 to the first accommodating cavity 121, and then synchronously drives the abutting part 21 to slide outward from the second accommodating cavity 122. As the driving ring 3 continues to move downward, the abutting part 21 abuts against the outer wall of the opening end 41; when the pressure-receiving part 22 is completely retracted in the first accommodating cavity 121, the abutting part 21 produces a large degree of extrusion deformation, and the abutting force between the abutting part 21 and the outer wall of the opening end 41 is further increased.

[0040] In some embodiments of the present application, in order to make the abutting portion 21 better fit with the open end 41 of the bottle body 4 and increase the contact area with the open end 41 of the bottle body 4, an arcuate surface 213 arranged coaxially with the connecting portion 12 can be provided on the side of the abutting portion 21 facing away from the pressure-bearing portion 22. When the abutting portion 21 abuts against the outer wall of the open end 41 of the bottle body 4, the abutting portion 21 can be tightly fitted with the outer wall of the open end 41 of the bottle body 4.

[0041] In some embodiments of the present application, the material of the abutting portion 21 is rubber, and the rubber also helps to increase the friction resistance between the abutting portion 21 and the open end 41 of the bottle body 4; since the rubber has a certain degree of deformation, when the driving ring 3 moves downward to force the abutting portion 21 to slide out of the second accommodating cavity 122 and abut against the outer wall of the open end 41, the greater the distance the driving ring 3 moves downward, the greater the amplitude of the squeeze deformation of the abutting portion 21 (the greater the friction resistance between the abutting portion 21 and the outer wall of the open end 41); according to the use requirements, the corresponding The distance that the driving ring 3 moves downward is controlled accordingly, so that there are different degrees of abutment forces between the abutment portion 21 and the outer wall of the opening end 41. If the shaking amplitude of the environment in which the bottle body 4 is located is small, only a small abutment force is needed to meet the demand (which helps the user save the physical strength required for screwing the driving ring 3); if the shaking amplitude of the environment in which the bottle body 4 is located is large, the distance that the driving ring 3 moves downward is increased, so that the lower end surface of the driving ring 3 passes over the pressure-bearing portion 22, thereby increasing the abutment force between the abutment portion 21 and the opening end 41.

[0042] In some embodiments of the present application, Figure 3 、 Figure 4 As shown, a rotating plate 13 is coaxially mounted on the lower end face of the sealing portion 11 (the rotating plate 13 is rotatably mounted on the sealing portion 11 via a rotating bearing), and a bearing circular plate 14 is movably provided on the lower end face of the rotating plate 13 along the axial direction of the connecting portion 12, and a rubber pad is provided on the lower end face of the bearing circular plate 14, and an elastic member is provided between the bearing circular plate 14 and the rotating plate 13; the projection of the bearing circular plate 14 along the axial direction of the connecting portion 12 is larger than the projection of the opening of the open end 41 along the axial direction of the connecting portion 12.

[0043] When the annular cover 1 is assembled on the open end 41 of the bottle body 4, the lower end surface of the supporting circular plate 14 abuts against the upper end surface of the open end 41 to seal the opening. A rubber pad is provided at the bottom of the supporting circular plate 14 to improve the sealing performance. Figure 4 As shown, the elastic member is also provided so that the supporting circular plate 14 is always subjected to a force acting downward against the upper end surface of the opening end 41, thereby improving the sealing effect on the opening end 41 of the bottle body 4. Even if the annular cover 1 is slightly loose relative to the opening end 41 of the bottle body 4, the supporting circular plate 14 is always in contact with the upper end surface of the opening end 41 under the action of the elastic member, which can further reduce the risk of cosmetics leaking from the bottle body 4.

[0044] In some embodiments of the present application, at least two guide posts 131 are provided at intervals on the lower end face of the rotating plate 13, and a guide cylinder 141 is provided on the upper end face of the supporting circular plate 14, which is slidably mounted with the guide posts 131, and a spring is connected between the guide posts 131 and the guide cylinder 141. When the annular cover 1 needs to be assembled on the open end 41, the connecting portion 12 is first aligned with the open end 41 and the open end 41 is inserted into the connecting portion 12, and then the sealing portion 11 is screwed so that the connecting portion 12 and the open end 41 are threadedly connected; during the screwing process, the lower end face of the supporting circular plate 14 is always pressed against the upper end face of the open end 41 and as the screwing continues, the spring connected between the guide posts 131 and the guide cylinder 141 is continuously compressed; during the screwing process, since the rubber pad is in contact with the upper end face of the open end 41 and the friction resistance between the rubber pad and the upper end face of the open end 41 is large, the rotating plate 13 is caused to rotate relative to the sealing portion 11; as shown in FIG. Figure 4 As shown in , when the upper end surface of the guide cylinder 141 abuts against the lower end surface of the rotating plate 13, the screwing action is stopped, and the assembly connection between the annular cover body 1 and the open end 41 of the bottle body 4 is completed.

[0045] In a second aspect, the present application provides a cosmetic bottle, such as Figure 1 As shown, it includes a bottle body 4, which has an upwardly protruding open end 41; the bottle cap in the above embodiment is threadedly assembled on the outer wall of the open end 41; an annular locking groove 411 is coaxially arranged on the outer wall of the open end 41, and the height of the annular locking groove 411 along the axial direction of the bottle body 4 matches the height of the abutment portion 21 along the axial direction of the bottle body 4.

[0046] When the locking cam 22 is in the closed position, the locking cam 22 is in the closed position, and the locking cam 22 is in the closed position, so that the locking cam 22 is in the closed position.

[0047] The working process of the present invention is as follows: align the connecting portion 12 with the open end 41 and screw the sealing portion 11 so that the annular cover body 1 is assembled on the open end 41 of the bottle body 4, so that the annular cover body 1 is installed in place. At this time, the multiple abutting portions 21 and the annular locking groove 411 provided on the outer wall of the open end 41 are in corresponding positions, and then the driving ring 3 is screwed and moved down in the annular groove 211 and squeezes the pressure-receiving portion 22, forcing the abutting portion 21 to extend from the second accommodating cavity 122, so that when the pressure-receiving portion 22 is completely retracted in the first accommodating cavity 121, at least part of the abutting portion 21 extends into the annular locking groove 411, and the upper and lower ends of the abutting portion 21 are snapped together with the upper and lower walls of the annular locking groove 411, thereby achieving locking and positioning of the annular cover body 1, effectively preventing the annular cover body 1 from loosening relative to the bottle body 4.

[0048] In summary, the embodiment of the present invention provides a bottle cap and a cosmetic bottle. In this solution, a plurality of abutting members 2 are arranged at intervals along the circumference of the bottle cap, and the driving ring 3 cooperates with the abutting members 2, so that when the bottle cap is assembled on the open end 41 of the cosmetic bottle, the abutting portion 21 abuts against the outer wall of the open end 41, thereby increasing the friction resistance of the bottle cap relative to the cosmetic bottle, thereby minimizing the probability of the bottle cap becoming loose when the cosmetic bottle is shaken in a handbag; at the same time, a spring is provided in the cap body to elastically abut against the open end 41. The supporting circular plate 14 is in contact with the supporting circular plate 14, and a rubber pad is provided on the lower end surface of the supporting circular plate 14, so that the rubber pad is always tightly pressed against the end surface of the opening end 41 under the action of elastic force to ensure the sealing effect of the opening end 41; the present solution also provides a cosmetic bottle and an annular locking groove 411 is provided on the outer wall of the opening end 41 thereof to cooperate with the abutting portion 21. When the bottle cap is assembled on the cosmetic bottle, the abutting portion 21 is at least partially inserted into the annular locking groove 411, thereby further improving the locking effect of the bottle cap.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
