Abstract
Description
Technical Field
[0001] This invention relates to a liquid dispensing device for a liquid container. Background Technology
[0002] Currently, all kinds of liquid bottles for daily necessities on the market are used upright, and liquid remains at the bottom of the bottle and cannot be completely drained, resulting in waste; in addition, the existing pump suction structure has poor versatility and cannot completely suck the liquid out of the bottle. Summary of the Invention
[0003] This invention provides a device that allows ordinary bottles to be used upside down, absorb liquid from the bottom, leave no residue, and prevent leakage simply by changing the bottle cap.
[0004] The device includes a cover, a base, and a liquid dispensing assembly.
[0005] The cap is attached to a standard bottle opening, and the cap and base are detachably connected.
[0006] The cap body contains a cap valve and a pin, while the base contains a pusher and a drain pipe.
[0007] When the base is installed, the pusher opens the pin, and the valve opens to allow liquid to flow out; when the base is removed, the valve automatically closes to prevent leakage.
[0008] When the bottle is inverted, the liquid flows to the bottom by gravity and enters the liquid outlet component through the drain pipe, achieving residue-free use.
[0009] Beneficial effects
[0010] 1. No need to change to a special bottle, just change the cap.
[0011] 2. Inverted bottom suction, virtually no liquid residue remains in the bottle.
[0012] 3. Install the conductor, remove the closure, and it will automatically prevent leakage.
[0013] 4. Simple structure, easy to use, and reusable. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] like Figure 1 As shown, this device includes a conventional bottle body 1, an automatic cap valve 2, a cap ejector pin 3, a cap valve 4, a base pusher 5, a drain pipe 6, a base 7, a pump head 8, and a pump body 9. The automatic cap valve 2 is installed on the ordinary bottle mouth and is detachably connected to the base 7. The base pusher 5 is located inside the base 7. When the base 7 is connected to the cap body, the base pusher 5 pushes open the cap ejector pin 3, causing the cap valve 4 to open. Under the action of gravity, the liquid in the bottle enters the pump body 9 through the drain pipe 6, and the liquid is discharged by pressing the pump head 8. After the base 7 is removed, the cap valve 4 automatically closes to prevent leakage.
[0019] When in use, attach the cap to a regular bottle and invert the bottle; connect the base to the cap, the pusher opens the pin, the cap valve opens, and the liquid enters the pump body through the drain pipe. Press the pump head to dispense the liquid; after removing the base, the cap valve closes automatically, preventing leakage.
Claims
1. An inverted bottom-suction liquid dispensing device, characterized in that, The system includes a cap, a base, and a liquid dispensing assembly. The cap is used to connect to a standard bottle neck, and the cap and base are detachably connected. The cap contains a bottle cap valve and a push pin, while the base contains a pusher and a drain pipe that extends to the bottom of the bottle. The drain pipe can be an independent pipeline, an internal flow channel integrally formed with the base, or a flow guide channel directly installed inside the bottle. When the base is installed, the pusher opens the push pin to open the valve, and when it is removed, the valve automatically closes to prevent leakage. When the bottle is inverted, the liquid enters the liquid dispensing assembly through the drain pipe under gravity.
2. The apparatus according to claim 1, characterized in that, The detachable connection is a detachable structure that can achieve a stable connection and a leak-proof seal, including but not limited to threaded connections, snap-fit connections, plug-in connections, magnetic connections, etc.
3. The apparatus according to claim 1, characterized in that, The bottle cap valve is a one-way valve or a self-closing valve, and the liquid dispensing assembly is a manual pump or an electric pump.
