[0042] Example: Figure 1-22 As shown, a cosmetic dropper container includes a cap 100, a bottle body 200, a base 300, an air bladder 400, and a sealing ring 500. The cap 100 is fitted onto the first end of the bottle body 200, the base 300 is fixedly installed at the second end of the bottle body 200, the air bladder 400 is installed inside the base 300, and the sealing ring 500 is fixed on the base 300. The sealing ring 500 and the air bladder 400 together seal the base 300 to fix the air bladder 400 to the base 300.

[0043] In this application, the base 300, airbag 400, and sealing ring 500 constitute a base assembly. The bottle body 200 and the base assembly form a cavity, which is used to store liquid or semi-solid materials 240, such as essential oils, serums, and water-oil separators. The base 300 is fixedly installed at the bottom of the bottle body 200, and the airbag 400 is installed in the base 300, sealing the opening of the base 300. The sealing ring 500 is fixed to the top of the inner wall of the base 300 by ultrasonic welding or adhesive bonding, and the bottom of the sealing ring 500 is press-fitted with the airbag 400. The airbag 400 is made of a deformable elastic material, and the bottle cap 100 is used to seal the bottle body 200.

[0044] In use, the user presses the air bladder 400 towards the inside of the bottle 200. The air bladder 400 deforms to compress the air inside the bottle 200, causing the material 240 inside the bottle 200 to be discharged from the first end of the bottle 200 for the user to use. The user can discharge the material by pressing the air bladder 400 with one hand and control the discharge volume by controlling the number of presses and the pressure applied. Therefore, it is simple to operate, convenient to use, and the discharge volume is easy to control, without causing material contamination. The sealing ring 500 connects the base 300 and the air bladder 400, improving the bonding strength between the air bladder 400 and the base 300. Compared with traditional dropper bottles, the dropper container in this application does not require the dropper to be pulled out of the dropper bottle, thus avoiding material contamination and waste. The bottle 200 in this application is designed similarly to a dropper; the material 240 is only discharged from the bottle 200 when the air bladder is under pressure. After use, even if the bottle 200 is placed horizontally on a table, there will be no leakage of the material 200.

[0045] like Figure 2 As shown, the sealing ring 500 is installed inside the base 300. The first end of the sealing ring 500 extends radially outward to form a protruding edge 510, which is fixedly connected to the base 300. The sealing ring 500 is press-fitted with the inner wall of the base 300, and the second end of the sealing ring 500 is press-fitted with the airbag 400. The sealing ring 500 is a cylindrical structure with open ends at the top and bottom. The upper open end extends radially outward to form a protruding edge 510, the lower surface of which is connected to the base 300, and the lower open end is connected to the airbag 400. The outer wall of the protruding edge 510 is press-fitted with the inner wall of the base 300.

[0046] like Figure 2 , Figure 20-22As shown, the lower surface of the protruding edge 510 is ultrasonically welded to the upper surface of the base 300. Optionally, the lower surface of the protruding edge 510 is provided with multiple ultrasonic points 511, which are distributed in a circle along the lower surface of the protruding edge 510, and the protruding edge 510 is ultrasonically welded through the ultrasonic points 511. The ultrasonic welding of the sealing ring 500 to the base 300 improves the bonding strength between the sealing ring 500 and the base 300, and the interference fit of the sealing ring 500 into the airbag 400 further improves the bonding strength between the sealing ring 500 and the airbag 400.

[0047] like Figure 2 and Figure 14-17 As shown, an outer ring 310 and an inner ring 320 are fixedly provided on the base 300. The outer ring 310 is located outside the inner ring 320. An installation groove 312 is provided between the outer ring 310 and the inner ring 320. A connecting part 220 is provided on the bottle body 200. The connecting part 220 is inserted into the installation groove 312.

[0048] like Figure 2 and Figure 14-15 As shown, the outer side wall of the connecting part 220 is provided with a first buckle 221, and the inner side wall of the outer ring 310 is provided with a second buckle 311. The connecting part 220 and the outer ring 310 are engaged and fixed by the first buckle 221 and the second buckle 311. The connecting part 220 of the bottle body 200 is inserted into the mounting groove 312 of the base 300, and the outer ring 310 is engaged and fixed with the connecting part 220, thereby improving the bonding strength and installation stability of the two.

[0049] like Figure 2 , Figure 15 and Figure 18 As shown, the inner ring 320 extends radially inward along the base 300 to form a first protrusion 321, and the airbag 400 extends radially outward to form a second protrusion 410 and a support portion 430. A fixing groove 420 is formed between the second protrusion 410 and the support portion 430, and the first protrusion 321 is inserted into the fixing groove 420. Optionally, the second end of the sealing ring 500 is interference-fitted to the second protrusion 410.

[0050] like Figure 2 As shown, the inner surface of the support portion 430 is attached to the outer surface of the base 300, and the second protrusion 410 is placed on the first protrusion 321. The airbag 400 has an arc-shaped structure. When the user presses the airbag 400, the airbag 400 deforms towards the inside of the bottle body 200, squeezing the air inside the bottle to expel the material. The support portion 430 is used for the quick reset of the airbag 400.

[0051] like Figure 4 , Figure 10 and Figure 13-14As shown, a discharge nozzle 210 is fixedly provided on the bottle body 200. The discharge nozzle 210 has an interconnected discharge hole 211 and a discharge channel 212. The diameter of the discharge channel 212 gradually decreases along the axis of the bottle body 200, with the upward orientation of the discharge nozzle 210 as the positive direction. A sealing post 120 is provided on the inner side of the bottle cap 100. The bottle cap 100 covers the discharge nozzle 210, and the sealing post 120 is inserted into the discharge hole 211 to seal the discharge hole 211. The discharge nozzle 210 is fixedly provided at the first end of the bottle body 200, and a connecting part 220 is fixedly provided at the second end of the bottle body 200. The connecting part 220 is used to connect to the base 300, and the discharge nozzle 210 is used for discharging material.

[0052] like Figure 13-14 As shown, the structure of the nozzle 210 includes a conical structure, and the outer wall of the bottle body 200 is provided with external threads 230, such as... Figure 10 As shown, the inner wall of the bottle cap 100 is provided with an internal thread 110, such as... Figure 4 As shown, the bottle cap 100 and the bottle body 200 are fixed together by an internal thread 110 and an external thread 230.

[0053] like Figure 14 As shown, the first end of the discharge channel 212 is connected to the discharge hole 211, and the second end of the discharge channel 212 is connected to the inner cavity of the bottle body 200. The structure of the discharge channel 212 includes a conical structure. The conical structure includes a cone, a pyramid, an oblique cone, a truncated cone (frustum, prismatic cone), an elliptical cone, etc. Optionally, the discharge nozzle 210 and the discharge channel 212 are frustum or prismatic structures.

[0054] During assembly, first install the airbag 400 onto the base 300, then ultrasonically weld the sealing ring 500 onto the base 300, and then insert the joint 220 of the bottle body 200 into the mounting groove 312 of the base 300 to fix the bottle body 200 and the base 300 together. After filling the bottle body 200 with material 240, cover the bottle cap 100 onto the discharge nozzle 210 of the bottle body 200, insert the sealing post 120 into the discharge hole 211 of the discharge nozzle 210, and screw the bottle cap 100 and the discharge nozzle 210 together.

[0055] In use, the user removes the bottle cap 100 and presses the air bladder 400. The air bladder 400 deforms towards the inside of the bottle body 200, squeezing the air inside the bottle to expel the material 240 through the discharge channel 212 and discharge hole 211 for the user to use. When the user releases the air bladder 400, the air bladder 400 returns to its original position. Because the discharge nozzle 210 faces downwards during use, all the material 240 in the bottle body 200 can be used up, saving resources.

[0056] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
