Description

Technical Field

[0001] This utility model belongs to the field of liquid storage bottles, and in particular relates to a liquid storage bottle for quantitative liquid dispensing. Background Technology

[0002] Most ordinary liquid packaging bottles on the market currently use volume markings on the cap to indicate the amount to be used. In actual use, the contents need to be carefully poured into the cap first, and then transferred, which is a rather cumbersome process and makes it difficult to control the amount used. You need to pay attention to the volume when pouring the contents from the bottle to the cap. Utility Model Content

[0003] The technical objective of this utility model is to provide a liquid storage bottle for quantitative liquid dispensing, which aims to solve the technical problems of ordinary liquid packaging bottles in related technologies, which require the liquid to be poured into the cap first, making the operation steps cumbersome and the dosage control difficult.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: a liquid storage bottle for quantitative dispensing includes a bottle body, a measuring device, and a bottle cap. The bottle body has a liquid storage chamber and a bottle opening communicating with the liquid storage chamber. The measuring device is detachably connected to the bottle opening and has a first cavity forming a liquid outlet and a second cavity communicating with the liquid storage chamber. The first cavity and the second cavity are connected or disconnected by a one-way valve. When the bottle opening is facing downwards, the contents of the liquid storage chamber flow to the second cavity, and the one-way valve is used to disconnect the first cavity and the second cavity. When the liquid storage bottle is flipped so that the bottle opening is facing upwards, the one-way valve is used to connect the first cavity and the second cavity. The first cavity is used for quantitative dispensing. The bottle cap is detachably connected to the end of the measuring device away from the bottle body.

[0005] Furthermore, in some embodiments, the second cavity has an inlet that connects to the liquid storage tank, and the end of the second cavity away from the inlet also has a connecting port that connects to the first cavity. The one-way valve is located in the second cavity and is used to close or open the connecting port so that the first cavity and the second cavity are disconnected or connected.

[0006] Furthermore, in some embodiments, the second cavity is provided with an inwardly protruding boss at the end away from the liquid inlet, and the communication port is opened on the boss.

[0007] Furthermore, in some embodiments, the second cavity is provided with a plurality of ribs arranged at circumferential intervals, and the one-way valve moves along the ribs to close or open the communication port.

[0008] Furthermore, in some embodiments, the measuring device further includes a connecting tube, which passes through the end of the first cavity away from the liquid outlet to connect the first cavity and the liquid storage tank.

[0009] Furthermore, in some embodiments, the connecting tube extends to the bottom of the bottle body, and an anti-clogging cut surface is provided at one end of the connecting tube near the bottom of the bottle.

[0010] Furthermore, in some embodiments, the bottle cap has a first surrounding bone protruding axially, and the measuring device has an arc-shaped protrusion on the side with the liquid outlet, and the first surrounding bone is attached to the arc-shaped protrusion.

[0011] Furthermore, in some embodiments, the liquid storage bottle further includes a sealing ring, which is clamped between the measuring device and the bottle opening.

[0012] Furthermore, in some embodiments, the measuring device includes a main body and a first cover, the first cavity and the second cavity are formed in the main body, the first cover is detachably connected to the side of the main body where the liquid outlet is provided, and the first cover is provided with a clearance opening aligned with the liquid outlet.

[0013] Furthermore, in some embodiments, the first covering portion is provided with a first buckle, and the main body portion is provided with a first buckle, the first buckle being connected to the first buckle.

[0014] Furthermore, in some embodiments, the first covering portion is provided with a first bone position, the main body portion protrudes with a second surrounding bone, the second surrounding bone is disposed within the first bone position; and the first buckle bone protrudes within the first bone position, and the first buckle protrudes from the second surrounding bone.

[0015] The quantitative dispensing storage bottle of this invention has the following advantages compared with related technologies:

[0016] When measuring the liquid in the storage chamber, first invert the bottle so that the opening faces downwards. The contents of the storage chamber can then flow directly into the second chamber. Because the one-way valve disconnects the first and second chambers, the liquid is stored only in the second chamber. Next, invert the bottle again to open the one-way valve, connecting the first and second chambers and allowing the liquid in the second chamber to flow into the first chamber. Finally, open the cap and tilt the bottle to allow the liquid to flow out through the outlet. The first chamber can be used for metering. Thus, after two inversions of the storage bottle, a fixed volume of liquid can be dispensed at once without needing to pour it into the cap, and the amount dispensed does not need to be manually controlled, making the operation convenient and quick.

[0038] Please see Figures 1 to 6This utility model provides a liquid storage bottle for quantitative dispensing, including a bottle body 1, a measuring device 2, and a bottle cap 3. The bottle body 1 has a liquid storage chamber 11 and a bottle opening 12 communicating with the liquid storage chamber 11. The measuring device 2 is detachably connected to the bottle opening 12 and has a first cavity 211 forming a liquid outlet 2111 and a second cavity 212 communicating with the liquid storage chamber 11. The first cavity 211 and the second cavity 212 are connected or disconnected by a one-way valve 22. When the bottle opening 12 is facing down, the contents of the liquid storage chamber 11 flow to the second cavity 212, and the one-way valve 22 is used to disconnect the first cavity 211 and the second cavity 212. When the liquid storage bottle is flipped so that the bottle opening 12 is facing up, the one-way valve 22 is used to connect the first cavity 211 and the second cavity 212. The first cavity 211 is used for quantitative dispensing. The bottle cap 3 is detachably connected to the end of the measuring device 2 away from the bottle body 1.

[0039] In this embodiment of the invention, when it is necessary to measure the liquid in the storage tank 11, the storage bottle can be inverted so that the bottle opening 12 faces downwards. At this time, the contents of the storage tank 11 can flow directly into the second cavity 212. Since the one-way valve 22 disconnects the first cavity 211 and the second cavity 212, the liquid is stored only in the second cavity 212. Then, the storage bottle is inverted again so that the one-way valve 22 is opened, and the first cavity 211 and the second cavity 212 are connected, allowing the liquid in the second cavity 212 to flow into the first cavity 211. Finally, the bottle cap 3 is opened and the bottle body 1 is tilted so that the liquid flows to the outside through the outlet 2111. The first cavity 211 can be used to achieve quantitative dispensing. Thus, after inverting the storage bottle twice, a quantitative dispensing can be achieved, and a fixed volume of liquid can be poured out at once without pouring into the bottle cap 3. The amount used does not need to be controlled manually, making the operation convenient and quick.

[0040] For example, such as Figure 6 As shown, the wavy lines represent the liquid in the first cavity 211 and the second cavity 212, while the arrows inside the storage bottle indicate the direction of liquid flow.

[0041] Furthermore, in some embodiments, the second cavity 212 has an inlet 2121 that connects to the liquid storage tank 11, and the end of the second cavity 212 away from the inlet 2121 is also provided with a connecting port 2122A that connects to the first cavity 211. A one-way valve 22 is located in the second cavity 212 and is used to close or open the connecting port 2122A so that the first cavity 211 and the second cavity 212 are disconnected or connected.

[0042] Specifically, the first cavity 211 can be a large liquid cavity, and the second cavity 212 can be a small liquid cavity. In the lateral direction, the first cavity 211 and the second cavity 212 can be isolated by an isolation wall. In addition, the measuring device 2 is also provided with a connecting structure that connects the first cavity 211 and the second cavity 212 and is partially located on the outside of the second cavity 212. There is a flow gap between the inner side of the connecting structure and the outer periphery of the second cavity 212, which connects the liquid storage tank 11 and the liquid inlet 2121. At the same time, in the axial direction, when the bottle body 1 is placed upright, there is a gap between the connecting port 2122A of the second cavity 212 and the wall surface of the bottom side of the first cavity 211, so that the first cavity 211 not only has a cavity space arranged side by side with the second cavity 212 in the lateral direction, but also has a cavity space located on the bottom side of the first cavity 211. In addition, in the axial direction, when the bottle body 1 is placed upright, the liquid inlet 2121 of the second cavity 212 is located above the connecting port 2122A.

[0043] With this configuration, when the bottle body 1 is inverted with the bottle opening 12 facing downwards, the contents of the liquid storage chamber 11 can first flow into the flow gap, and then enter the second chamber 212 from bottom to top through the liquid inlet 2121. At the same time, it can push the one-way valve 22 in the second chamber 212 to the connecting port 2122A, thereby disconnecting the first chamber 211 and the second chamber 212. When the second chamber 212 is full of liquid, the bottle body 1 can be flipped over again so that the bottle body 1 is upright. During this process, under the action of buoyancy, the one-way valve 22 moves away from the connecting port 2122A, thereby connecting the first chamber 211 and the second chamber 212. Under the action of gravity, the liquid in the second chamber 212 can flow to the first chamber 211 through the connecting port 2122A.

[0044] Furthermore, in some embodiments, the end of the second cavity 212 away from the liquid inlet 2121 is provided with an inwardly protruding boss 2122, and the communication port 2122A is opened on the boss 2122.

[0045] Specifically, the end of the second cavity 212 away from the liquid inlet 2121 is the wall of the cavity. A boss 2122 is provided on the wall, and a connecting port 2122A for connecting the liquid storage chamber 11 is opened on the boss 2122. In this way, the connecting port 2122A can be higher than the wall of the second cavity 212, so that the one-way valve 22 can fit more closely to the connecting port 2122A. At the same time, an effective buoyancy area can be reserved for the one-way valve 22, so that when the bottle body 1 is turned upright again, the one-way valve 22 can open the connecting port 2122A under the action of buoyancy.

[0046] Understandably, the one-way valve 22 can be an object that can block or open the communication port 2122A under the action of liquid buoyancy. For example, the one-way valve 22 can be a float or the like.

[0047] Furthermore, in some embodiments, the second cavity 212 is provided with a plurality of ribs 2123 arranged at intervals along the circumference, and the one-way valve 22 moves along the ribs 2123 to close or open the communication port 2122A.

[0048] Specifically, by providing ribs 2123 in the second cavity 212, the movement of the one-way valve 22 can be guided, restricting the one-way valve 22 to move only along the axial direction, so that the one-way valve 22 will not be eccentric when floating; at the same time, when the bottle body 1 is flipped to make the bottle body 1 upright, the liquid can flow between the ribs 2123, so that the liquid can flow smoothly downward, thereby generating buoyancy on the one-way valve 22, which is conducive to the one-way valve 22 opening or closing the communication port 2122A.

[0049] In some embodiments, the measuring device 2 further includes a connecting tube 23, which passes through one end of the first cavity 211 away from the liquid outlet 2111 to connect the first cavity 211 and the liquid storage tank 11.

[0050] Specifically, the first cavity 211 can serve as a quantitative dispensing cavity, and the second cavity 212 can serve as a transfer chamber. Axially, when the bottle 1 is placed upright, a through hole is formed on the bottom wall of the first cavity 211, and a connecting tube 23 is disposed within the through hole. A small bone is provided within the through hole to securely mount the connecting tube 23 within it. Furthermore, the connecting tube 23 has a first end and a second end. The first end is located in the first cavity 211, and the second end is located within the liquid storage chamber 11. Thus, during the transfer of liquid from the second cavity 212 to the first cavity 211, when the liquid surface in the first cavity 211 is higher than the end face of the first end of the connecting tube 23, the excess liquid will flow through the connecting tube 23 into the liquid storage chamber 11, making the liquid surface in the first cavity 211 flush with the end face of the first end. This allows for quantitative dispensing within the first cavity 211. In addition, the connecting pipe 23 can also serve as an air inlet channel for the liquid storage tank 11, maintaining the air pressure balance inside the liquid storage tank 11 and ensuring the smooth flow of liquid.

[0051] Furthermore, the capacity of the second cavity 212 needs to be greater than or equal to the capacity of the first cavity 211. Thus, the liquid transferred from the second cavity 212 to the first cavity 211 will either have its liquid level flush with the first end face of the connecting pipe 23 or exceed the first end face of the connecting pipe 23, allowing it to flow back to the storage tank 11 through the connecting pipe 23. Additionally, when the capacity of the second cavity 212 is equal to the capacity of the first cavity 211, the second cavity 212 can also serve as a metering cavity.

[0052] Furthermore, in some embodiments, the connecting tube 23 is movable relative to the first cavity 211, and the connecting tube 23 may be provided with a scale. Thus, by moving the position of the connecting tube 23, the liquid volume from the bottom side of the first cavity 211 to the end face of the first end of the connecting tube 23 can be changed, thereby achieving adjustable dispensing volume each time. This allows for changing the dispensing volume, enabling multiple dispensing volumes to be achieved with a single storage bottle. When a fixed dispensing volume needs to be changed, only the connecting tube 23 needs to be moved; there is no need to replace it with a new storage bottle or store multiple storage bottles simultaneously, reducing costs. It is understood that in this embodiment, quantitative dispensing refers to single quantitative dispensing, not quantitative dispensing each time.

[0053] Furthermore, in some embodiments, the connecting tube 23 is stationary relative to the first cavity 211, and the bottom side of the first cavity 211 is an open end with an adjusting cup. Thus, the actual liquid output is the liquid volume from the bottom of the adjusting cup to the end face of the first end of the connecting tube 23. The adjusting cup can move relative to the first cavity 211, and it is marked with graduations. Therefore, by adjusting the relative position of the adjusting cup and the first cavity 211, the distance from the bottom of the adjusting cup to the end face of the first end of the connecting tube 23 can be changed, thereby changing the liquid output. Thus, multiple liquid outputs can be achieved using a single storage bottle. When a fixed liquid output needs to be changed, only the adjusting cup needs to be moved; there is no need to replace the storage bottle with a new one, or to store multiple storage bottles simultaneously, reducing costs. It is understood that in this embodiment, quantitative liquid output refers to a single quantitative liquid output, not quantitative liquid output each time.

[0054] Furthermore, in some embodiments, the connecting tube 23 extends to the bottom of the bottle body 1, and an anti-clogging cut surface is provided at one end of the connecting tube 23 near the bottom of the bottle body 1.

[0055] Specifically, after the liquid in the second chamber 212 is transferred to the first chamber 211, during the process of tilting the bottle body 1 to transfer the liquid in the first chamber 211 to the outside, because the extension length of the connecting pipe 23 in the liquid storage tank 11 is long enough, even if some liquid in the liquid storage tank 11 flows towards the connecting pipe 23, it will only stay in the connecting pipe 23, thus preventing the liquid in the liquid storage tank 11 from flowing to the first chamber 211 through the connecting pipe 23. In addition, by setting an anti-blocking section, the connecting pipe 23 can be prevented from being blocked, allowing the liquid above the first end face of the connecting pipe 23 to flow smoothly to the liquid storage tank 11 through the connecting pipe 23, thereby ensuring that a quantitative measure is achieved in the first chamber 211.

[0056] In some specific embodiments, the connecting tube 23 may include an air passage cylinder that passes through the end of the first cavity 211 away from the liquid outlet 2111, and a suction tube connected to the end of the air passage cylinder away from the first cavity 211, which can realize quantitative liquid discharge from the first cavity 211 and also realize air pressure balance.

[0057] Understandably, in some embodiments, the air pump and the straw can be integrally formed.

[0058] Furthermore, in some embodiments, the bottle cap 3 has a first surrounding bone 31 protruding along the axial direction, and the measuring device 2 has an arc-shaped protrusion 213 on one side of the liquid outlet 2111, with the first surrounding bone 31 fitting against the arc-shaped protrusion 213.

[0059] Specifically, the outlet 2111 is the outlet 2111 of the first cavity 211, and the arc-shaped protrusion 213 is provided on the measuring device 2 and close to the outlet 2111 of the first cavity 211. The bottle cap 3 is connected to the measuring device 2; and, in the axial direction, when the bottle body 1 is placed upright, the protruding part of the arc-shaped protrusion 213 is located below the arc surface, and the first rib 31 and the arc-shaped protrusion 213 fit tightly together, thus improving the sealing of the connection between the bottle cap 3 and the measuring device 2.

[0060] Furthermore, in some embodiments, the bottle cap 3 and the measuring device 2 can be threadedly connected. For example, the bottle cap 3 can be provided with an internal thread, and the measuring device 2 can be provided with an external thread, allowing the internal and external threads to connect. It is understood that in other embodiments, the bottle cap 3 and the measuring device 2 can also be connected by other detachable methods such as snap-fit ​​connections.

[0061] Furthermore, in some embodiments, the bottle body 1 and the measuring device 2 can be threadedly connected. For example, the bottle body 1 can be provided with an external thread, and the measuring device 2 can be provided with an internal thread, such that the internal and external threads are connected. It is understood that in other embodiments, the measuring device 2 and the bottle body 1 can also be connected in other detachable ways; for example, they can be connected by snap-fit.

[0062] Furthermore, in some embodiments, the liquid storage bottle also includes a sealing ring 4, which is clamped between the measuring device 2 and the bottle mouth 12. By providing the sealing ring 4, the connection and sealing between the measuring device 2 and the bottle body 1 can be improved.

[0063] Furthermore, in some embodiments, the measuring device 2 includes a main body 21 and a first cover 24, a first cavity 211 and a second cavity 212 formed in the main body 21, the first cover 24 being detachably connected to the side of the main body 21 where the liquid outlet 2111 is provided, and the first cover 24 being provided with a clearance opening 243 aligned with the liquid outlet 2111.

[0064] Specifically, the measuring device 2 can be divided into a main body 21 and a first cover 24. The main body 21 includes a connecting structure that connects the inner cavity to the inner cavity and partially surrounds the inner cavity. Part of the cavity wall of the inner cavity is the cavity wall of the first cavity 211, and another part of the cavity wall is the cavity wall of the second cavity 212. An isolation wall is also provided inside the inner cavity, which divides the inner cavity into the first cavity 211 and the second cavity 212. In addition, when the bottle 1 is placed upright, the bottom side of the second cavity 212 is located above the bottom side of the first cavity 211. Furthermore, the first cover 24 is provided on the side of the main body 21 where the liquid outlet 2111 is provided, that is, when the bottle 1 is placed upright, the first cover 24 is connected to the top side of the main body 21. By opening a clearance opening 243 on the first cover portion 24 that is aligned with the liquid outlet 2111, the liquid in the first cavity 211 can flow out to the outside in sequence through the liquid outlet 2111 and the clearance opening 243.

[0065] Furthermore, in some specific embodiments, there is a flow gap connecting the liquid storage tank 11 on the inner side of the connecting structure and the outer periphery of the second cavity 212; the first cover part 24 is connected to the connecting structure and covers the liquid inlet 2121 and the flow gap of the second cavity 212. The first cover part 24 and the main body part 21 are relatively inclined to include a liquid inlet channel connecting the flow gap and the liquid inlet 2121, so that the second cavity 212 can be connected to the liquid storage tank 11, and the liquid in the second cavity 212 can be prevented from flowing directly to the outside.

[0066] Furthermore, in some embodiments, the first covering portion 24 is provided with a first fastening bone 242, and the main body portion 21 is provided with a first buckle 215, the first buckle 215 being connected to the first fastening bone 242. Through the cooperation of the first buckle 215 and the first fastening bone 242, the assembly connection between the main body portion 21 and the first covering portion 24 can be realized.

[0067] Furthermore, in some embodiments, the first covering portion 24 is provided with a first bone position 241, and the main body portion 21 protrudes with a second surrounding bone 214, which is disposed within the first bone position 241. In this way, the connection stability between the main body portion 21 and the first covering portion 24 can be improved, and the connection sealing between the main body portion 21 and the first covering portion 24 can also be guaranteed.

[0068] Furthermore, in some specific embodiments, the first buckle 242 protrudes from the first bone position 241, and the first buckle 215 protrudes from the second surrounding bone 214. This further improves the sealing performance of the connection between the main body 21 and the first covering portion 24.

[0069] Furthermore, in some specific embodiments, in addition to the first bone position 241 provided on the outer peripheral side, the first covering part 24 may also be provided with a first bone position 241 at the position where the clearance opening 243 is provided, and the main body part 21 is provided with a second surrounding bone 214 at the corresponding position, so as to improve the sealing performance.

[0070] Furthermore, in some embodiments, the measuring device 2 further includes a second covering part 25 connected to the inner cavity and arranged axially opposite to the first covering part 24. When the bottle body 1 is placed upright, the second covering part 25 is on the wall surface of the bottom side of the first cavity 211, the wall surface of the bottom side of the second cavity 212 is located above the second covering part 25, and the connecting tube 23 is disposed on the second covering part 25.

[0071] Furthermore, in some embodiments, the second covering part 25 is provided with a second buckle 216, and the inner cavity is provided with a second buckle 252. The second buckle 216 is engaged with the second buckle 252, which can realize the assembly connection between the inner cavity of the main body part 21 and the second covering part 25.

[0072] Furthermore, in some embodiments, the second covering portion 25 is provided with a second bone position 251, and the peripheral sidewall of the inner cavity is disposed within the second bone position 251. In this way, the connection stability between the inner cavity of the second covering portion 25 and the main body portion 21 can be improved, and the sealing performance can also be guaranteed.

[0073] Furthermore, in some specific embodiments, the second buckle 216 is disposed on the peripheral sidewall of the inner cavity, and the second buckle bone 252 protrudes from the second bone position 251 of the second cover portion 25, thereby further improving the connection and sealing performance between the inner cavity of the main body portion 21 and the second cover portion 25.

[0074] In some embodiments, the first covering portion 24 may be integrally formed with the metering chamber.

[0075] Furthermore, in some embodiments, the second cover 25 can be a cap with a fixed capacity, and the second cover 25 is fixedly assembled with the inner cavity of the main body 21. In this case, one liquid storage bottle can only correspond to one liquid dispensing volume, and when it is necessary to change the liquid dispensing volume, a new liquid storage bottle must be replaced.

[0076] In some embodiments, the second covering portion 25 may further be provided with a cup body, which has graduation marks and is axially movable and connected to the inner cavity of the main body portion 21. Changing the relative position of the cup body and the inner cavity of the main body portion 21 changes the liquid output of the second cavity 212. Thus, when it is necessary to change the liquid output, only the cup body needs to be moved. It is understood that in this embodiment, quantitative dispensing means that a fixed volume can be poured out at once, but it is not limited to the same dispensing volume each time.

[0077] Furthermore, in some embodiments, the bottle body 1 and the measuring device 2 can be made of transparent material, or the bottle body 1 and the measuring device 2 can be provided with a viewing window, so that the user can directly observe or observe the flow path of the liquid inside the bottle body 1 through the viewing window, and better grasp the flow of the liquid.
