Description

Technical Field

[0001] This application relates to the field of cosmetic bottle technology, and in particular to a cosmetic stirrer and cosmetic packaging bottle. Background Technology

[0002] In the cosmetics industry, cream or liquid cosmetic bottles serve as the primary containers for storing and transporting cosmetics, and their performance and quality directly affect the preservation effect and user experience of the cosmetics.

[0003] Existing cosmetic bottles include a bottle body and a cap detachably connected to the bottle body. A brush for picking up cosmetics from the bottle is slidably mounted on the cap. The cap has a movable head that drives the brush to slide and a pressing spring that forces the movable head to return to its original position. Users press the movable head to move the brush and stir the cosmetics in the bottle before use. However, simply moving the brush up and down to stir the cosmetics results in poor mixing, thus requiring further improvement. Utility Model Content

[0004] In order to improve the uniformity of mixing of cosmetics in a bottle, one of the purposes of this application is to provide a stirrer for cosmetics.

[0005] The cosmetic mixer provided in this application adopts the following technical solution: A cosmetic stirrer includes a stirrer body built into a bottle. The stirrer body includes a stirring head and a stirring spring fixedly connected to the lower end face of the stirring head. The lower end of the stirring spring abuts against or is fixed to the inner wall of the bottom of the bottle.

[0006] By adopting the above technical solution, the user can press the movable head to move the brush pen downwards. The lower part of the brush pen pushes the stirring end head downwards, thereby causing the stirring spring to compress and deform. During the deformation of the stirring end head and the stirring spring, the cosmetics in the bottle are stirred, improving the mixing uniformity of the cosmetics in the bottle.

[0007] Preferably, the upper end face of the stirring end has a through opening.

[0008] Preferably, the stirring spring has a flat cross-section, and the spring sheet of the stirring spring has a flow hole through it along the axial direction.

[0009] By adopting the above technical solution, the stirring spring is designed with a flat cross-section, which increases the contact area between the stirring spring and the cosmetics inside the bottle, further improving the stirring effect. Simultaneously, the stirring spring's spring plate has axially spaced flow holes, enhancing the agitation of the cosmetics inside the bottle and ensuring more uniform mixing.

[0010] To improve the uniformity of mixing of cosmetics within the bottle, a second objective of this application is to provide a cosmetic packaging bottle.

[0011] A cosmetic packaging bottle includes a bottle body, a bottle cap, and a cosmetic stirrer. The bottle cap is detachably connected to the upper part of the bottle body. A brush for dipping cosmetics into the bottle body is slidably inserted through the bottle cap. The bottle cap is provided with a movable head that drives the brush to slide and a pressing spring that forces the movable head to return to its original position. The lower part of the brush abuts against the stirring end.

[0012] By adopting the above technical solution, the user can press the movable head to move the brush pen downwards. The lower part of the brush pen pushes the stirring end head downwards, thereby causing the stirring spring to compress and deform. During the deformation of the stirring end head and the stirring spring, the cosmetics in the bottle are stirred, improving the mixing uniformity of the cosmetics in the bottle.

[0013] Preferably, the upper end face of the bottle body is coaxially fixedly connected to a connecting screw sleeve, and the lower end face of the bottle cap is coaxially provided with a first threaded hole that is threaded and fitted into the connecting screw sleeve.

[0014] By adopting the above technical solution, the bottle body and the bottle cap are detachably connected through the connecting screw sleeve and the first threaded hole, ensuring the stability and sealing of the bottle cap.

[0015] Preferably, the upper end face of the bottle cap is coaxially provided with a sliding blind hole, the movable head is slidably inserted into the sliding blind hole, the lower end face of the movable head is coaxially provided with a mounting cavity, the upper end of the brush is fixedly connected to the inner wall of the mounting cavity, the pressing spring is sleeved on the brush, the upper end of the pressing spring abuts against the top inner wall of the mounting cavity, and the lower end of the pressing spring abuts against the bottom inner wall of the sliding blind hole.

[0016] By adopting the above technical solution, the sliding head moves more smoothly within the sliding blind hole, improving user convenience. Simultaneously, the design of the mounting cavity makes the connection between the brush pen and the sliding head more secure, ensuring the brush pen will not loosen during vertical movement. A pressing spring is fitted onto the brush pen and forms an elastic support between the mounting cavity and the sliding blind hole, effectively ensuring the reliability of the sliding head's reset.

[0017] Preferably, the brush pen includes a brush rod that slides through the bottle cap and a brush head installed at the lower end of the brush rod. The upper part of the brush head has a protrusion. The outer diameter of the protrusion is larger than the outer diameter of the brush rod and smaller than the inner diameter of the opening. The outer diameter of the protrusion is larger than the inner diameter of the stirring spring.

[0018] By adopting the above technical solution, the brush head has a protrusion to ensure that the brush head and brush rod can be smoothly inserted into the opening when the brush moves downward. When the lower end of the brush head is inserted into the inner hole of the stirring spring, the protrusion abuts against the upper spring piece of the stirring spring, so that the stirring spring is forced to deform when the brush rod continues to move downward, thereby agitating the cosmetics in the bottle.

[0019] Preferably, a limiting ring is coaxially fixedly connected to the lower part of the brush rod, and the limiting ring abuts against the upper end face of the stirring head.

[0020] By adopting the above technical solution, when the brush moves downward, the brush head and brush rod are smoothly inserted into the through-hole and the brush head is inserted into the upper inner hole of the stirring spring. When the limiting ring abuts against the upper end face of the stirring end, the brush rod continues to move downward, and the limiting ring pushes the stirring end to move downward, thereby forcing the stirring spring to compress and deform.

[0021] In summary, this utility model has the following beneficial effects: 1. By pressing the movable head, the user moves the brush pen downwards. The lower part of the brush pen pushes the stirring end head downwards, which causes the stirring spring to compress and deform. During the deformation of the stirring end head and the stirring spring, the cosmetics in the bottle are stirred, improving the uniformity of the mixing of the cosmetics in the bottle. 2. The stirring spring is designed with a flat cross-section, which increases the contact area between the stirring spring and the cosmetics inside the bottle, further improving the stirring effect. Simultaneously, the stirring spring's spring plate has axially spaced flow holes to enhance the agitation of the cosmetics inside the bottle, ensuring more uniform mixing.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] Example 1: This application discloses a cosmetic packaging bottle, as shown in the embodiments below. Figure 1 , Figure 2 The device includes a bottle body 1, a bottle cap 2 detachably connected to the upper part of the bottle body 1, and a stirrer body 3 built into the bottle body 1. A connecting screw sleeve 11 is coaxially fixedly connected to the upper end face of the bottle body 1, and the inner hole of the connecting screw sleeve 11 communicates with the inner cavity of the bottle body 1. The lower end face of the bottle cap 2 is coaxially provided with a first threaded hole 21 that is threaded and fitted into the connecting screw sleeve 11.

[0026] Reference Figure 2 , Figure 3 The stirrer body 3 includes a stirring head 31 and a stirring spring 32 coaxially fixed to the lower end face of the stirring head 31. In this embodiment, the lower end of the stirring spring 32 abuts against the inner wall of the bottom of the bottle body 1. The cross-section of the stirring spring 32 is a flat structure. In this embodiment, the cross-section of the stirring spring 32 is square. In other embodiments, the cross-section of the stirring spring 32 is trapezoidal. The upper end face of the stirring head 31 is provided with a through-hole 33 and a liquid flow channel 34 located outside the through-hole 33. The liquid flow channel 34 is connected to the through-hole 33.

[0027] A sliding blind hole 22 is coaxially formed on the upper end face of the bottle cap 2, and a through hole 23 communicating with the first threaded hole 21 is coaxially formed on the bottom wall of the sliding blind hole 22. The bottle cap 2 is provided with a movable head 4 that slides into the sliding blind hole 22, and a mounting cavity 41 is coaxially formed on the lower end face of the movable head 4. A brush 5 for dipping cosmetics in the bottle body 1 is slidably inserted through the bottle cap 2. The brush 5 includes a mounting block 51 fixedly connected to the inner wall of the mounting cavity 41, a brush rod 52 fixedly connected to the lower end face of the mounting block 51 and slidably inserted through the through hole 23, and a brush head 53 installed at the lower end of the brush rod 52. The bottle cap 2 is provided with a pressing spring 24 sleeved on the upper part of the brush rod 52. The upper end of the pressing spring 24 abuts against the lower end face of the mounting block 51, and the lower end of the pressing spring 24 abuts against the bottom inner wall of the sliding blind hole 22.

[0028] The lower end face of the brush rod 52 is coaxially provided with a second threaded hole 521, and the upper end face of the brush head 53 is coaxially fixedly connected with a stud 531 threaded into the second threaded hole 521. Both the lower part of the brush rod 52 and the brush head 53 can pass through the through-hole 33. The upper part of the brush head 53 has a protrusion 532. The outer diameter of the protrusion 532 is larger than the outer diameter of the brush rod 52 and smaller than the inner diameter of the through-hole 33. The outer diameter of the protrusion 532 is larger than the inner diameter of the stirring spring 32.

[0029] The implementation principle of a cosmetic stirrer in this application embodiment is as follows: the user moves the brush 5 downward by pressing the movable head 4. When the lower end of the brush head 53 is inserted into the inner hole of the stirring spring 32, the protrusion 532 abuts against the upper spring piece of the stirring spring 32. When the brush rod 52 continues to move downward, it forces the stirring spring 32 to deform, thereby agitating the cosmetic in the bottle 1 and improving the mixing uniformity of the cosmetic in the bottle 1.

[0030] Example 2: The difference from Example 1 is that, referring to Figure 4 The stirring spring 32 has a spring plate that passes through and has a liquid flow hole 35 along the axial direction. There are multiple liquid flow holes 35 and they are distributed around the axis of the stirring spring 32.

[0031] Example 3: The difference from Example 1 is that, referring to Figure 5 A limiting ring 522 is coaxially fixedly connected to the lower part of the brush rod 52, and the limiting ring 522 abuts against the upper end face of the stirring end 31. When the brush 5 moves downward, the brush head 53 and the brush rod 52 smoothly pass through the through-hole 33 and the brush head 53 is inserted into the upper inner hole of the stirring spring 32. When the limiting ring 522 abuts against the upper end face of the stirring end 31, as the brush rod 52 continues to move downward, the limiting ring 522 pushes the stirring end 31 downward to force the stirring spring 32 to compress and deform.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
