The switch buckle body has a gate-shaped structure. Both ends of the switch buckle body are rotatably connected to the left and right sides of the bottle body. The limiting block is fixedly connected to the inner side of the switch buckle body and abuts against the upper side of the stopper. A first arc surface is provided on the lower side of the limiting block, and a protrusion is provided on the upper side of the stopper. The protrusion abuts against the first arc surface and is located on the front and rear sides of the lowest point of the first arc surface. Second arc surfaces are provided on the front and rear sides of the stopper to avoid the limiting block.
[0007] With the above settings, the dropper assembly can be pulled out of the bottle by turning the switch buckle forward or backward to take out the cosmetic. After use, the dropper assembly can be inserted back into the bottle and the switch buckle can be turned back to reseal the dropper bottle. The sealing structure of this application changes the traditional threaded sealing form. When taking out cosmetic, there is no need to perform multiple rotation operations, making the operation more convenient and improving the user experience.
[0008] Furthermore, from the middle to the end, the width of the stopper gradually decreases, and the protrusion is close to the end of the stopper.
[0009] With the above settings, the bottle stopper is less likely to interfere with the switch buckle.
[0010] Furthermore, the width of the switch body is w1, and the outer diameter of the elastic button is w2. <w1 / w2<1.5。
[0011] With the above settings, the switch buckle body can protect the elastic button and prevent it from being pressed accidentally.
[0012] Furthermore, the distance from the upper inner wall of the switch body to the upper end of the elastic button is d, 2mm. <d<10mm。
[0013] By adopting the above design, the height of the switch buckle body is minimized to reduce the volume of the dropper bottle and make it easier to carry.
[0014] Furthermore, mounting grooves are provided on the left and right ends of the upper side of the bottle body. The end faces of the left and right ends of the bottle stopper are flush with the groove walls of the mounting grooves. A rotating shaft is fixedly connected to the groove wall of the mounting groove. Rotating grooves are provided on both ends of the switch buckle body. The rotating shaft is set in the rotating groove. The two ends of the switch buckle body are rotatably connected to the bottle body through the rotating shaft.
[0015] Furthermore, the front and rear sides of the mounting groove wall, as well as the front and rear sides of the bottle stopper end, are all provided with chamfered surfaces.
[0016] The above settings prevent the switch buckle from jamming during rotation.
[0017] Furthermore, the bottom of the mounting groove is horizontal, and the sealing structure is in an open state. When in the open state, the main body of the switch buckle is horizontal, and the bottom of the mounting groove supports the end of the main body of the switch buckle.
[0018] The above settings limit the rotation range of the switch buckle. Attached Figure Description

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0025] like Figures 1 to 5 As shown, a dropper 42 bottle sealing structure includes a bottle body 3, a dropper assembly 4, and a switch buckle 5. The dropper assembly 4 includes an elastic button 41, a dropper 42, and a bottle stopper 43. The elastic button 41 is located on the upper side of the bottle stopper 43. The upper end of the dropper 42 is connected to the elastic button 41. The dropper 42 is inserted into the bottle body 3, and the bottle stopper 43 is embedded in the bottle mouth of the bottle body 3. The switch buckle 5 includes a switch buckle body 51 and a limiting block 52. The switch buckle body 51 has a gate-shaped structure. The two ends of the switch buckle body 51 are rotatably connected to the left and right sides of the bottle body 3. The limiting block 52 is fixedly connected to the inner side of the switch buckle body 51 and abuts against the upper side of the bottle stopper 43. A first arc surface 53 is provided on the lower side of the limiting block 52. A protrusion 44 is provided on the upper side of the bottle stopper 43. The protrusion 44 abuts against the first arc surface 53. The protrusion 44 is located on the front and rear sides of the lowest point of the first arc surface 53. A second arc surface 6 is provided on the front and rear sides of the bottle stopper 43 to avoid the limiting block 52.
[0026] With the above settings, the dropper assembly 4 can be pulled out of the bottle body 3 by turning the switch buckle 5 forward or backward to take out the cosmetics. After use, the dropper assembly 4 can be inserted back into the bottle body 3, and the switch buckle 5 can be turned back to reseal the bottle body 3 of the dropper 42. The sealing structure of this application changes the traditional threaded sealing form. When taking out cosmetics, there is no need to perform multiple rotation operations, making the operation more convenient and improving the user experience.
[0027] The bottle body 3 of this application contains cosmetics. The upper end of the bottle body 3 is provided with a bottle opening that matches the stopper 43. After the dropper 42 of the dropper assembly 4 is inserted into the bottle opening, the stopper 43 can be directly inserted into the bottle opening and fit snugly against it, ensuring a good seal between the stopper 43 and the bottle opening. The elastic button 41 can be cylindrical, spherical, or other shapes, and can be designed according to needs. In this application, the elastic button 41 is basically a cylindrical structure, extending vertically on the upper side of the stopper 43. The switch buckle 5 is an integrally molded structure. The main body 51 of the switch buckle has a door-shaped structure, extending downwards at both ends and rotatably connected to the left and right sides of the bottle body 3. Figure 1The label indicates the front, back, left, and right directions of the dropper bottle 42. The switch buckle 5 can rotate forward or backward. Initially, the limiting block 52 abuts against the upper side of the bottle stopper 43 to prevent the bottle stopper 43 from detaching from the bottle mouth, ensuring the seal between the bottle stopper 43 and the bottle mouth. The middle part of the switch buckle body 51 extends left and right and is located above the elastic button 41, providing a certain shielding effect and preventing the elastic button 41 from being squeezed during the carrying of the dropper bottle 42. A protrusion 44 is provided on both the front and back sides of the lowest point of the first arc surface 53. The protrusion 44 abuts against the arc surface, preventing the switch buckle 5 from accidentally rotating forward or backward after being subjected to external force, thus preventing the switch buckle 5 from being accidentally opened. The switch buckle 5 is made of plastic and has a certain... The switch buckle 5 is designed to be flexible. When cosmetics need to be taken out, the switch buckle 5 is rotated forward or backward. The switch buckle 5 will undergo a certain elastic deformation. After the limiting block 52 passes the protrusion 44, the switch buckle 5 returns to its original position. In this application, the switch buckle 5 can rotate forward or backward by 90°. The second arc surface 6 is set to prevent the switch buckle 5 from interfering with the bottle stopper 43 during rotation, so that the switch buckle 5 can rotate to the correct position. After the switch buckle 5 rotates, the limiting block 52 moves away from the upper side of the bottle stopper 43, the bottle stopper 43 can be pulled upward from the bottle mouth, and the dropper assembly 4 can be removed from the upper end of the bottle body 3, so that cosmetics can be taken out. After use, the dropper 42 is reinserted into the bottle body 3, the bottle stopper 43 is inserted downward into the bottle mouth, the switch buckle 5 rotates back to the initial position, and the bottle body 3 is resealed.
[0028] As one implementation, the width of the stopper 43 gradually decreases from the middle to the end, and the protrusion 44 is close to the end of the stopper 43.
[0029] With the above settings, the bottle stopper 43 is less likely to interfere with the switch buckle 5.
[0030] The limiting block 52 of this application is basically set in the middle of the left and right ends of the switch buckle body 51. The limiting block 52 has a relatively small rotation radius. The bottle stopper 43 has a narrow width at both ends and a wide width in the middle, and is basically an elliptical structure extending in the left and right directions. The front and rear sides of the protrusion 44 are close to the edge of the bottle stopper 43. When the switch buckle 5 is rotated forward or backward, the limiting block 52 will not interfere with the bottle stopper 43 after passing the protrusion 44.
[0031] As one implementation, the width of the switch body 51 is w1, and the outer diameter of the elastic button 41 is w2. <w1 / w2<1.5。
[0032] With the above settings, the switch buckle body 51 can protect the elastic button 41 and prevent the elastic button 41 from being pressed accidentally.
[0033] As one implementation method, the distance from the upper inner wall of the switch body 51 to the upper end of the elastic button 41 is d, 2mm. <d<10mm。
[0034] By adopting the above design, the height of the switch buckle body 51 is shortened as much as possible, thereby reducing the volume of the dropper 42 bottle and making it easier to carry.
[0035] As one implementation method, the upper left and right ends of the bottle body 3 are provided with mounting grooves, the end faces of the left and right ends of the bottle stopper 43 are flush with the groove wall 7 of the mounting groove, the groove wall 7 of the mounting groove is fixedly connected with a rotating shaft 8, the two ends of the switch buckle body 51 are provided with rotating grooves 9, the rotating shaft 8 is set in the rotating groove 9, and the two ends of the switch buckle body 51 are rotatably connected to the bottle body 3 through the rotating shaft 8.
[0036] As one implementation method, the front and rear sides of the groove wall 7 of the mounting groove, and the front and rear sides of the end face of the bottle stopper 43 are all provided with chamfered surfaces.
[0037] The above settings prevent the switch buckle 5 from getting stuck during rotation.
[0038] As one implementation method, the bottom of the mounting groove is horizontal, the sealing structure is in an open state, and when in the open state, the switch buckle body 51 is horizontal, and the bottom of the mounting groove supports the end of the switch buckle body 51.
[0039] The above settings limit the rotation range of switch buckle 5.
[0040] In this application, the maximum forward rotation angle of the switch buckle 5 is 90 degrees, and the maximum backward rotation angle is 90 degrees. After rotating 90 degrees forward or backward, the end of the switch buckle 5 abuts against the bottom of the mounting groove, and the switch buckle 5 can no longer rotate.
[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
