[0034] like Figures 1 to 5 As shown, an embodiment of the present application provides a dropper 100 and a medicine bottle 1000, wherein the medicine bottle is used to store liquids, such as eye drops, athlete's foot solution or other medicines, and other medicines such as wind oil, herbal wine, etc. are not limited here; the dropper 100 is installed on the medicine bottle 1000, so that the liquid in the medicine bottle 1000 can be discharged through the dropper 100, and the dropper 100 can condense the discharged medicine into droplets, which is convenient for the user to accurately drop the liquid into the eyes or other parts to be implemented; the medicine bottle 1000 can control the flow rate of the liquid discharged from the dropper 100, which is convenient for the user to control the amount of medicine applied, improve the treatment effect, and improve the utilization rate of the medicine.

[0035] First, as Figure 1 As shown, an embodiment of the present application provides a dropper 100 , which includes a dropper body 110 , a liquid inlet ring 130 and an assembly ring 140 .

[0036] like Figure 1 As shown, the dropper body 110 is a sleeve-shaped structure with openings at both ends; the dropper body 110 includes a first end 102 and a second end 104 arranged in sequence along a first direction, and the direction from the first end 102 to the second end 104 is the first direction, the dropper body 110 has a liquid outlet at the first end 102, and the dropper body 110 has a liquid inlet at the second end 104, and the liquid in the medicine bottle 1000 can enter the dropper body 110 from the liquid inlet of the second end 104 and be discharged from the liquid outlet at the first end 102; during use, the first end 102 is located below the second end 104 in the direction of gravity, so that the liquid flows from the second end 104 to the first end 102.

[0037] like Figure 1As shown, a convex portion 120 is provided at the liquid outlet of the first end portion 102, and the end surface of the convex portion 120 close to the liquid outlet is a first arc surface 122; under the action of the first arc surface 122, the liquid discharged from the liquid outlet can condense into drops, and when the user uses it, by calculating the number of times the liquid is dripped, the amount of medicine can be calculated, thereby controlling the amount of medicine used each time, ensuring the treatment effect, and avoiding excessive use of medicine. Exemplarily, the first arc surface 122 is an inner concave surface; in another embodiment, the first arc surface 122 is an outer convex surface.

[0038] like Figure 1 As shown, the liquid inlet ring 130 is sleeved on the liquid inlet of the second end 104, and the liquid inlet ring 130 is fixedly connected to the dropper body 110. The inner diameter of the liquid inlet ring 130 is smaller than the inner diameter of the liquid inlet, which can increase the resistance of the liquid in the medicine bottle 1000 entering the inside of the dropper body 110 from the liquid inlet of the second end 104, reduce the flow rate and flow rate of the liquid inside the dropper 100, and facilitate the control of the liquid discharge amount, so as to prevent the liquid from directly flowing out of the liquid outlet of the first end 102 without condensing into drops on the first arc surface 122, so as to cause excessive discharge of liquid.

[0039] Exemplarily, the liquid inlet ring 130 is coaxially arranged with the dropper body 110 ; in another embodiment, the axis of the liquid inlet ring 130 and the axis of the dropper body 110 are not located on the same straight line.

[0040] Exemplarily, the dropper 100 is made of plastic material, and the liquid inlet ring 130 is integrally formed with the dropper body 110. In another embodiment, the liquid inlet ring 130 is sleeved on the dropper body 110, and the liquid inlet ring 130 and the dropper body 110 have an interference fit, so that the liquid inlet ring 130 is fixed relative to the dropper body 110.

[0041] like Figure 1 As shown, exemplarily, the liquid inlet ring 130 is provided with a first channel 132, and the first channel 132 connects the liquid inlet of the second end 104 to the internal space of the medicine bottle 1000, and the liquid enters the liquid inlet of the second end 104 through the first channel 132; the first channel 132 is a through hole, and the inner diameter of the first channel 132 gradually decreases along the first direction, and the inner diameter of the outlet of the first channel 132 is larger than the inner diameter of the inlet of the first channel 132, so that the first channel 132 can reduce the flow rate of the liquid, and the inner wall at the outlet of the first channel 132 is close to the inner wall of the dropper body 110, which can promote the liquid to flow along the inner wall of the dropper body 110 and increase the contact area between the liquid and the inner wall of the dropper body 110, and can reduce the flow rate of the liquid while taking into account the effective discharge of the liquid, so that the user can better control the liquid discharge volume and improve the user experience.

[0042] like Figure 1As shown, the assembly ring 140 is fixedly sleeved on the dropper body 110, and the assembly ring 140 is located between the protrusion 120 and the liquid inlet ring 130. The assembly ring 140 has a first end face 142 and a second end face 144, and the first end face 142 and the second end face 144 are sequentially distributed along the first direction. The first end face 142 is perpendicular to the axial direction of the dropper body 110, and the side of the second end face 144 close to the dropper body 110 is inclined at a first preset angle α relative to the first end face 142 in a direction away from the first end face 142, so that the dropper 100 is easily inserted into the medicine bottle 1000. The outer diameter of the assembly ring 140 is larger than the outer diameter of the liquid inlet ring 130, and the dropper body 110 and the medicine bottle 1000 are sealed and matched through the assembly ring 140 to prevent liquid leakage.

[0043] Exemplarily, the first preset angle α ranges from 20° to 45°, that is, 20°≤α≤45°. Exemplarily, the first preset angle α=20°. Exemplarily, the first preset angle α=25°. Exemplarily, the first preset angle α=30°. Exemplarily, the first preset angle α=45°.

[0044] Exemplarily, the mounting ring 140 is coaxially disposed with the dropper body 110 ; in another embodiment, the axis of the mounting ring 140 and the axis of the dropper body 110 are not located on the same straight line.

[0045] Exemplarily, the dropper 100 is made of plastic; exemplary, the assembly ring 140 is integrally formed with the dropper body 110; in another embodiment, the assembly ring 140 is sleeved on the dropper body 110, and the assembly ring 140 and the dropper body 110 have an interference fit, so that the assembly ring 140 is fixed relative to the dropper body 110.

[0046] like Figure 1 As shown, in one embodiment, the dropper 100 also includes a stop ring 150, which is fixedly mounted on the dropper body 110, and is disposed between the protrusion 120 and the assembly ring 140. The outer diameter of the stop ring 150 is greater than the outer diameter of the assembly ring 140. The stop ring 150 can limit the depth of the dropper body 110 inserted into the medicine bottle 1000, so that the protrusion 120 is located outside the medicine bottle 1000, which is convenient for liquid dripping.

[0047] Exemplarily, the stop ring 150 is coaxially disposed with the dropper body 110. In another embodiment, the axis of the stop ring 150 and the axis of the dropper body 110 are not located on the same straight line.

[0048] Exemplarily, the stop ring 150 is integrally formed with the dropper body 110. In another embodiment, the stop ring 150 is sleeved on the dropper body 110, and the stop ring 150 and the dropper body 110 are interference fit, so that the stop ring 150 is fixed relative to the dropper body 110.

[0049] like Figure 1 As shown, in one embodiment, three assembly rings 140 are arranged at intervals, and the three assembly rings 140 are respectively a first assembly ring, a second assembly ring and a third assembly ring. The first assembly ring, the second assembly ring and the third assembly ring are arranged in sequence along the first direction, and the interval between the first assembly ring and the second assembly ring is greater than the interval between the second assembly ring and the third assembly ring, so that the sealing positions of the assembly rings 140 and the medicine bottle 1000 are dispersed. When the part of the medicine bottle 1000 that seals with the assembly ring 140 is slightly deformed, the deformation of the first assembly ring after being squeezed can be reduced, and the first assembly ring, the second assembly ring and the third assembly ring can still seal with the medicine bottle 1000 to the greatest extent, thereby improving the sealing performance, and can also improve the adaptability and reliability of the dropper body 110, thereby avoiding the situation where all the assembly rings 140 fail to seal after the part of the medicine bottle 1000 that seals with the assembly ring 140 is deformed.

[0050] like Figure 1 As shown, in one embodiment, there is a gap between the assembly ring 140 and the stop ring 150. Exemplarily, there is a gap between the first assembly ring and the stop ring 150, which further improves the deformation resistance of the assembly ring and improves the sealing performance.

[0051] Second, as Figures 2 to 5 As shown, an embodiment of the present application provides a medicine bottle 1000, which includes a bottle body 200, and a mounting tube 240 is provided on the bottle body 200 for connecting the external space with the internal space of the bottle body 200. The mounting tube 240 is a sleeve-shaped structure. The mounting tube 240 and the bottle body 200 are integrally formed. In another embodiment, the mounting tube 240 and the bottle body 200 are separately provided, and the mounting tube 240 is threadedly sealed and installed on the bottle body 200.

[0052] The medicine bottle 1000 also includes a dropper 100 as in any of the above embodiments, the second end 104 of the dropper 100 is inserted into the mounting tube 240, exemplarily, the liquid inlet ring 130, the first assembly ring, the second assembly ring and the third assembly ring are inserted into the mounting tube 240, the first assembly ring, the second assembly ring and the third assembly ring are sealed to match the mounting tube 240, and the outer diameters of the first assembly ring, the second assembly ring and the third assembly ring match the inner diameter of the mounting tube 240; the stop ring 150 is located outside the mounting tube 240, and the outer diameter of the stop ring 150 is greater than the inner diameter of the mounting tube 240. The outer diameters of the first assembly ring, the second assembly ring and the third assembly ring are set accordingly according to the inner diameter of the mounting tube 240; exemplarily, the inner diameter of the mounting tube 240 remains unchanged along the first direction, then the outer diameters of the first assembly ring, the second assembly ring and the third assembly ring are equal and equal to the inner diameter of the mounting tube. In another embodiment, the inner diameter of the mounting tube 240 gradually increases along the first direction, then the outer diameters of the first assembly ring, the second assembly ring and the third assembly ring gradually increase.

[0053] The medicine bottle 1000 also includes an adjusting component, which is used to adjust the liquid intake of the dropper 100 and further adjust the liquid discharge of the dropper 100 .

[0054] like Figure 2 As shown, in one embodiment, the adjustment assembly includes a stopper 210 , a matching channel is provided on the mounting tube 240 , and the stopper 210 is mounted on the matching channel.

[0055] The stopper 210 is located at one end of the mounting tube 240 close to the second end 104 of the dropper 100 . The stopper 210 can move along the radial direction of the mounting tube 240 to completely or partially block the liquid inlet of the liquid inlet ring 130 .

[0056] Along the radial direction of the mounting tube 240, the closer the stopping portion 210 is to the axis of the mounting tube 240, the greater the degree to which the stopping portion 210 blocks the liquid inlet of the liquid inlet ring 130, the smaller the volume of liquid entering the liquid inlet ring 130 per unit time, and thus the smaller the volume of the droplets condensed at the first end 102 of the dropper 100.

[0057] Along the radial direction of the mounting tube 240, the farther the stopping portion 210 is from the axis of the mounting tube 240, the smaller the degree to which the stopping portion 210 blocks the liquid inlet of the liquid inlet ring 130, the larger the volume of liquid entering the liquid inlet ring 130 per unit time, and the larger the volume of droplets condensed at the first end 102 of the dropper 100.

[0058] By controlling the distance of the stopper 210 relative to the axis of the mounting tube 240, the degree to which the stopper 210 blocks the liquid inlet of the liquid inlet ring 130 can be controlled, thereby facilitating accurate control of the dosage of each medication.

[0059] In one embodiment, Figure 2 As shown, the stopping portion 210 is a plate structure, the stopping portion 210 is slidably sealed with the matching channel and the stopping portion 210 is arranged along the radial direction of the mounting tube 240, and the stopping portion 210 can move along the radial direction of the mounting tube 240 to fully or partially block the liquid inlet of the liquid inlet ring 130.

[0060] Exemplarily, at least one sealing ring is provided on the inner wall of the matching channel, and the stopping portion 210 is sealed and matched with the matching channel through the sealing ring.

[0061] In another embodiment, the technical solution in which the stopper 210 of the above embodiment is a plate structure can also be replaced by the following technical solution:

[0062] The stopping part 210 is a threaded rod structure, which is threadedly connected to the matching channel and is arranged along the radial direction of the mounting tube 240. The stopping part 210 rotates and moves along the radial direction of the mounting tube 240 to fully or partially block the liquid inlet of the liquid inlet ring 130.

[0063] like Figure 3 and Figure 4 As shown, in another embodiment, the technical solution of the adjustment component in the above embodiment can be replaced by the following technical solution:

[0064] The adjustment assembly includes an internal thread ring 220, which is sleeved on the mounting tube 240. A mating thread 230 is provided on the outer wall of the mounting tube 240 near the second end 104. The major diameter of the mating thread 230 gradually increases along the second direction. The second direction is along the axial direction of the mounting tube 240 and is a direction from the mounting tube 240 to the bottle body 200. The second direction is parallel to the first direction.

[0065] The internal thread ring 220 and the mounting tube 240 are threadedly matched via the matching thread 230 , and the internal thread ring 220 can rotate and move axially at the same time.

[0066] The internal thread ring 220 is rotated forward and moves along the second direction on the matching thread 230, so that the internal thread ring 220 squeezes the mounting tube 240 through the matching thread 230. The inner walls of the mounting tube 240 are squeezed and move closer to each other, and the inner diameter of the inner wall of the mounting tube 240 is reduced; the inner wall of the mounting tube 240 abuts against the outer wall of the liquid inlet ring 130, and the inner walls of the mounting tube 240 move closer to each other to squeeze the outer wall of the liquid inlet ring 130, so that the inner diameter of the liquid inlet port of the liquid inlet ring 130 is reduced. The volume of liquid entering the liquid inlet ring 130 per unit time is reduced, and thus the volume of the droplets condensed at the first end 102 of the dropper 100 is smaller.

[0067] The internal threaded ring 220 is rotated in the opposite direction and moves in the opposite direction of the second direction. The force of the internal threaded ring 220 squeezing the mounting tube 240 is reduced, and the mounting tube 240 rebounds, so that the inner walls of the mounting tube 240 move away from each other, so that the inner diameter of the mounting tube 240 increases; the force of the inner wall of the mounting tube 240 squeezing the outer wall of the liquid inlet ring 130 is reduced, the liquid inlet ring 130 rebounds, and the inner diameter of the liquid inlet ring 130 increases. Per unit time, the volume of liquid entering the liquid inlet ring 130 increases, and then the volume of droplets condensed at the first end 102 of the dropper 100 increases.

[0068] like Figure 5 As shown, in one embodiment, the medicine bottle 1000 also includes a bottle cap 300; Figure 2 and Figure 3 As shown, the bottle cap 300 is snapped onto the mounting tube 240 to block the liquid outlet of the first end 102. Exemplarily, the mounting tube 240 is provided with a snap-on protrusion, and the bottle cap 300 is provided with a snap-on groove that cooperates with the snap-on protrusion. When in use, the snap-on protrusion cooperates with the snap-on groove; the bottle cap 300 is also provided with a blocking block for blocking the liquid outlet at the first end 102 of the dropper 100.

[0069] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0070] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
