Description

Technical Field

[0001] This application relates to the field of dropper technology, and more particularly to a push-type dropper. Background Technology

[0002] A dropper bottle is a small container specifically designed for holding and dispensing liquid medications or other liquid substances. It is widely used in pharmaceuticals, health products, and cosmetics. These are plastic bottles made of LDPE, PET, or PVC, and typically range in size from 2.5ml to 20ml. Sleep-improving drops are a type of product designed to help improve sleep, and they are generally packaged in dropper bottles.

[0003] A search revealed that Chinese Patent CN215133405U discloses a push-type dropper bottle. This bottle features protective caps at both ends, with a screw-in squeezing device on the upper cap, allowing the medication to be dispensed without opening the upper cap. This prevents the medication from contacting air and causing contamination. However, due to the presence of the threaded rod and push rod, the bottle is quite long, making it inconvenient to package and carry. Additionally, Chinese Patent CN220069972U discloses a metering dropper bottle. Pressing a pressing plate moves a pressing rod downwards, which in turn moves a piston assembly downwards. The piston assembly squeezes air from the metering sleeve, forcing it into the dropper bottle through a one-way component, thus expelling the liquid from the dropper head. However, this method of introducing air easily leads to dropper contamination. Therefore, a push-type dropper bottle is proposed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a push-type dropper bottle to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A push-type dropper includes a bottle body and a cap fixedly connected to the top of the bottle body. A partition plate is fixedly connected to the inner bottom wall of the bottle body, dividing the inner cavity of the bottle body into a liquid storage chamber and a push-in chamber. A first piston is slidably connected to the inner wall of the liquid storage chamber. The liquid storage chamber and the push-in chamber are connected by a connecting channel. A pusher is provided in the push-in chamber, which can send air in the push-in chamber into the top of the first piston to push the first piston downward.

[0007] Preferably, the thruster is a second piston, and the surface of the second piston is slidably connected to the inner wall of the thrust chamber.

[0008] Preferably, a push handle is fixedly connected to the top of the second piston, and the top end of the push handle passes through the bottle cap and is fixedly connected to a fixing plate.

[0010] Preferably, a rotating block is rotatably connected to the inner wall of the groove. The rotating block is semi-cylindrical, and its thickness is less than the depth of the groove and not less than the height of the connecting flow channel and the air inlet channel. The diameter of the rotating block is equal to the diameter of the groove. A connecting shaft is fixedly connected to the bottom end of the rotating block, and a knob is fixedly connected to the bottom end of the connecting shaft. A damping ring made of rubber is sleeved on the surface of the connecting shaft. The damping ring abuts against the lower surface of the bottle body under the pressure of the knob.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-5 This utility model provides a push-type dropper bottle technical solution:

[0025] A push-type dropper includes a bottle body 1 and a cap 2 fixedly connected to the top of the bottle body 1. A partition plate 3 is fixedly connected to the inner bottom wall of the bottle body 1, dividing the inner cavity of the bottle body 1 into a liquid storage chamber 4 and a push-in chamber 5. A first piston 6 is slidably connected to the inner wall of the liquid storage chamber 4. The liquid storage chamber 4 and the push-in chamber 5 are connected by a connecting flow channel 7. A pusher is provided in the push-in chamber 5, which can send air in the push-in chamber 5 into the top of the first piston 6 to push the first piston 6 downward.

[0026] Specifically, by setting a propulsion chamber 5 in the inner cavity of the bottle body 1 and placing the propeller in the propulsion chamber 5, the overall length of the dropper bottle is reduced, making it convenient for packaging and carrying. By setting a first piston 6 and using the propeller to send air from the propulsion chamber 5 to the top of the first piston 6 to push the first piston 6 to move, the drops in the liquid storage chamber 4 are dripped out without the drops coming into contact with air, thus preventing them from being contaminated.

[0027] The propulsion device is the second piston 8. The surface of the second piston 8 is slidably connected to the inner wall of the propulsion chamber 5. By setting the second piston 8, the air in the propulsion chamber 5 is sent to the top of the first piston 6 by moving the second piston 8 downward.

[0028] The top of the second piston 8 is fixedly connected to a push handle 9. The top of the push handle 9 passes through the bottle cap 2 and is fixedly connected to a fixing plate 10. By setting the fixing plate 10, it is convenient for the user to pull out or push the push handle 9 to drive the piston to move.

[0029] The inner bottom wall of the propulsion chamber 5 is provided with a groove 11, and the connecting flow channel 7 is provided inside the partition plate 3. One end of the connecting flow channel 7 is connected to the upper part of the liquid storage chamber 4, and the other end of the connecting flow channel 7 is connected to the groove 11. The inner wall of the groove 11 is provided with an air inlet channel 12 that penetrates the surface of the bottle body 1. By setting the connecting flow channel 7, the air in the propulsion chamber 5 is guided into the top of the first piston 6 in the liquid storage chamber 4, and the outside air is introduced into the propulsion chamber 5 by setting the air inlet channel 12.

[0030] A rotating block 13 is rotatably connected to the inner wall of the groove 11. The rotating block 13 is semi-cylindrical. The thickness of the rotating block 13 is less than the depth of the groove 11 and not less than the height of the connecting flow channel 7 and the air inlet channel 12. The diameter of the rotating block 13 is equal to the diameter of the groove 11. A connecting shaft 14 is fixedly connected to the bottom end of the rotating block 13. A knob 15 is fixedly connected to the bottom end of the connecting shaft 14. A rubber damping ring 16 is sleeved on the surface of the connecting shaft 14. The damping ring 16 abuts against the lower surface of the bottle body 1 under the pressure of the knob 15. By rotating the knob 15, the rotating block 13 is driven to rotate, so that the rotating block 13 closes the connecting flow channel 7 or the air inlet channel 12. By setting the damping ring 16, the rotating block 13 is prevented from rotating arbitrarily.

[0031] A limit block 17 is provided on the lower surface of the bottle cap 2 to limit the second piston 8.

[0032] A limiting ring 18 is fixedly connected to the inner wall of the liquid storage chamber 4, and a dropper 19 connected to the liquid storage chamber 4 is fixedly connected to the surface of the bottle body 1. A cap 20 is detachably connected to the surface of the dropper 19. The dropper 19 and the cap 20 can be connected by a threaded connection or a bayonet connection.

[0033] Working principle: When using this push-type dropper bottle, the user first removes the cap 20, and then, in the initial state (i.e., with the rotating block 13 closing the connecting channel 7), pulls the fixing plate 10 upward. The fixing plate 10 drives the push handle 9 upward, which in turn drives the second piston 8 upward. At this time, as the second piston 8 moves upward, outside air enters the interior of the push chamber 5 through the air intake channel 12. When the second piston 8 contacts the limiting block 17, the upward pull stops. Then, the knob 15 is turned, which drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the rotating block 13 to rotate, causing the rotating block 13 to close the air intake channel 12. Then, the dropper 19 is aligned with the mouthpiece and pushed downward. Pressing the fixing plate 10 causes the fixing plate 10 to drive the push handle 9, which in turn drives the second piston 8 to move downwards. This sends the air in the propulsion chamber 5 through the connecting flow channel 7 into the top of the first piston 6 in the liquid storage chamber 4. As the air is introduced, the first piston 6 moves downwards, causing the drops in the liquid storage chamber 4 to flow out from the dropper 19. By setting the propulsion chamber 5 inside the bottle body 1 and placing the pusher inside the propulsion chamber 5, the overall length of the dropper bottle is reduced, making it easier to package and carry. The first piston 6 and the pusher send the air in the propulsion chamber 5 into the top of the first piston 6 to push the first piston 6 to move, causing the drops in the liquid storage chamber 4 to drip out without the drops coming into contact with the air, thus preventing contamination.
