[0002] At present, the common liquid packaging bottles on the market basically have capacity scales engraved on the lids, and the usage amount is identified through the scales on the lids. During actual use, the contents need to be carefully poured into the lid first and then transferred. The operation steps are relatively cumbersome, and it is troublesome to control the dosage. When pouring the contents from the bottle into the lid, attention needs to be paid to the capacity. Summary of the Invention

[0003] The technical object of the present invention is to provide a liquid storage bottle with quantitative liquid discharge, aiming to solve the technical problems in the related art that the common liquid packaging bottles need to pour the liquid into the lid first, with relatively cumbersome operation steps and troublesome dosage control.

[0004] To solve the above technical problems, the present invention is realized as follows. A liquid storage bottle with quantitative liquid discharge includes a bottle body, a measuring device, and a bottle cap. The bottle body has a liquid storage chamber and a bottle mouth communicating with the liquid storage chamber. The measuring device is detachably connected to the bottle mouth. The measuring device has a first chamber forming a liquid outlet and a second chamber communicating with the liquid storage chamber. The first chamber and the second chamber are connected or disconnected through a one-way valve member. When the bottle mouth is downward, the contents in the liquid storage chamber flow to the second chamber, and the one-way valve member is used to disconnect the first chamber and the second chamber. When the liquid storage bottle is flipped so that the bottle mouth is upward, the one-way valve member is used to connect the first chamber and the second chamber. The first chamber is used for quantitative liquid discharge. The bottle cap is detachably connected to one end of the measuring device away from the bottle body.

[0005] Further, in some embodiments, the second chamber has a liquid inlet communicating with the liquid storage chamber, and a communication port communicating with the first chamber is further opened at one end of the second chamber away from the liquid inlet. The one-way valve member is located in the second chamber, and the one-way valve member is used to close or open the communication port to disconnect or connect the first chamber and the second chamber.

[0006] Further, in some embodiments, a convex platform protruding inward is provided at one end of the second chamber away from the liquid inlet, and the communication port is opened on the convex platform.

[0007] Further, in some embodiments, a plurality of ribs are arranged at intervals in the circumferential direction in the second chamber, and the one-way valve member moves along the ribs to close or open the communication port.

[0008] Further, in some embodiments, the measuring device further includes a connecting pipe, which penetrates through one end of the first cavity away from the liquid outlet to communicate the first cavity and the liquid storage bin.

[0009] Further, in some embodiments, the connecting pipe extends to the bottom of the bottle body, and an anti-blocking section is provided at one end of the connecting pipe close to the bottom of the bottle.

[0010] Further, in some embodiments, the bottle cap axially protrudes a first surrounding rib, and a curved surface protrusion is provided on one side of the measuring device where the liquid outlet is provided, and the first surrounding rib fits against the curved surface protrusion.

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

[0012] Further, in some embodiments, the measuring device includes a main body portion and a first covering portion. The first cavity and the second cavity are formed in the main body portion. The first covering portion is detachably connected to one side of the main body portion where the liquid outlet is provided, and the first covering portion is provided with an avoidance opening aligned with the liquid outlet.

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

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

[0015] The liquid storage bottle with quantitative liquid outlet in the present invention, compared with the related art, has the beneficial effects that:

[0016] When it is necessary to measure the liquid in the liquid storage bin, the liquid storage bottle can be first turned over so that the bottle mouth of the bottle body faces downwards. At this time, the contents of the liquid storage bin can directly flow into the second cavity, and since the one-way valve member disconnects the first cavity and the second cavity, in this way, the liquid is only stored in the second cavity; then the liquid storage bottle is further turned over to open the one-way valve member, and the first cavity and the second cavity are communicated, so that the liquid in the second cavity flows into the first cavity, and finally the bottle cap is opened and the bottle body is tilted so that the liquid flows out through the liquid outlet to the outside. Among them, the first cavity can be used to achieve quantification. In this way, after turning over the liquid storage bottle twice, quantitative liquid outlet can be realized, and a fixed volume of liquid can be poured out at one time without pouring it into the bottle cap, and the amount used does not need to be controlled by oneself, and the operation is convenient and fast.

In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0038] Please refer to Figures 1 to 6 , the embodiment of the present invention provides a liquid storage bottle with quantitative liquid discharge, 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 mouth 12 communicating with the liquid storage chamber 11; the measuring device 2 is detachably connected to the bottle mouth 12, and the measuring device 2 has a first chamber 211 forming a liquid outlet 2111 and a second chamber 212 communicating with the liquid storage chamber 11; the first chamber 211 and the second chamber 212 are connected or disconnected through a one-way valve member 22; when the bottle mouth 12 is downward, the content in the liquid storage chamber 11 flows to the second chamber 212, and the one-way valve member 22 is used to disconnect the first chamber 211 and the second chamber 212; when the liquid storage bottle is turned over so that the bottle mouth 12 is upward, the one-way valve member 22 is used to connect the first chamber 211 and the second chamber 212; the first chamber 211 is used for quantitative liquid discharge; the bottle cap 3 is detachably connected to one end of the measuring device 2 away from the bottle body 1.

[0039] In an embodiment of the present invention, when it is necessary to measure the liquid in the liquid storage chamber 11, the liquid storage bottle can be first turned over so that the bottle mouth 12 of the bottle body 1 faces downward. At this time, the contents of the liquid storage chamber 11 can directly flow into the second cavity 212. And since the one-way valve member 22 disconnects the first cavity 211 and the second cavity 212, in this way, the liquid is only stored in the second cavity 212. Then, continue to turn over the liquid storage bottle so that the one-way valve member 22 is opened, and the first cavity 211 and the second cavity 212 are communicated, so that the liquid in the second cavity 212 flows into the first cavity 211. Finally, open the bottle cap 3 and tilt the bottle body 1 so that the liquid flows out through the liquid outlet 2111 to the outside. Among them, the first cavity 211 can be used for quantitative measurement. In this way, after turning over the liquid storage bottle twice, quantitative liquid discharge can be achieved, and a fixed volume of liquid can be poured out at one time without pouring it into the bottle cap 3, and the dosage does not need to be controlled by oneself, and the operation is convenient and fast.

[0040] Exemplarily, as Figure 6 shown, where the wavy line represents the liquid in the first cavity 211 and the second cavity 212, and at the same time, the arrow indicates the flow direction of the liquid in the liquid storage bottle.

[0041] Further, in some embodiments, the second cavity 212 has a liquid inlet 2121 communicating with the liquid storage chamber 11. At one end of the second cavity 212 away from the liquid inlet 2121, a communication port 2122A communicating with the first cavity 211 is also provided. The one-way valve member 22 is located in the second cavity 212, and the one-way valve member 22 is used to close or open the communication port 2122A so as to disconnect or connect the first cavity 211 and the second cavity 212.

[0042] Specifically, the first cavity 211 can be a large liquid cavity, and the second cavity 212 can be a small liquid cavity. Horizontally, the first cavity 211 and the second cavity 212 can be separated by a partition wall. In addition, the measuring device 2 is also provided with a connecting structure connecting the first cavity 211 and the second cavity 212 and partially disposed outside the second cavity 212. There is a flow gap between the inner side of the connecting structure and the outer peripheral side of the second cavity 212 communicating the liquid storage chamber 11 and the liquid inlet 2121. At the same time, axially, when the bottle body 1 is placed upright, there is a distance between the communication port 2122A of the second cavity 212 and the wall surface at 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 horizontally, but also has a cavity space at the bottom side of the first cavity 211. In addition, axially, when the bottle body 1 is placed upright, the liquid inlet 2121 of the second cavity 212 is located above the communication port 2122A.

[0043] With such a setting, when the bottle mouth 12 of the bottle body 1 is facing downward, that is, when the bottle body 1 is placed upside down, the contents in the liquid storage chamber 11 can first flow to the circulation gap, and then enter the second cavity 212 from bottom to top through the liquid inlet 2121. At the same time, the check valve member 22 in the second cavity 212 can be pushed to the communication port 2122A, so that the first cavity 211 and the second cavity 212 can be disconnected; when the second cavity 212 is filled with liquid, the bottle body 1 can be turned over again so that the bottle body 1 is placed upright. During this process, under the action of buoyancy, the check valve member 22 moves away from the position of the communication port 2122A, so that the first cavity 211 and the second cavity 212 can be communicated. Under the action of gravity, the liquid in the second cavity 212 can flow to the first cavity 211 through the communication port 2122A.

[0044] Further, in some embodiments, a convex platform 2122 protruding inward is provided at one end of the second cavity 212 away from the liquid inlet 2121, and the communication port 2122A is opened on the convex platform 2122.

[0045] Specifically, one end of the second cavity 212 away from the liquid inlet 2121 is the wall surface of the cavity. By providing a convex platform 2122 on the wall surface and opening a communication port 2122A communicating with the liquid storage chamber 11 on the convex platform 2122, in this way, the communication port 2122A can be higher than the wall surface of the second cavity 212, so that the check valve member 22 can fit more closely to the communication port 2122A. At the same time, an effective buoyancy area can be reserved for the check valve member 22, so that when the bottle body 1 is placed upright again, the check valve member 22 can be opened by the buoyancy force to open the communication port 2122A.

[0046] It can be understood that the check valve member 22 can be an object that can block or open the communication port 2122A under the action of liquid buoyancy. Exemplarily, the check valve member 22 can be a floating ball or the like.

[0047] Further, in some embodiments, a plurality of ribs 2123 arranged at intervals in the circumferential direction are provided in the second cavity 212, and the check valve member 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, it can play a guiding role in the movement of the check valve member 22, restricting the check valve member 22 to move only along the axial direction, so that the check valve member 22 will not be eccentric when floating; at the same time, when the bottle body 1 is turned over to place 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 check valve member 22, which is beneficial to the check valve member 22 to open or close the communication port 2122A.

[0049] In some embodiments, the measuring device 2 further includes a communicating pipe 23 which penetrates through one end of the first cavity 211 away from the liquid outlet 2111 to communicate the first cavity 211 and the liquid storage bin 11.

[0050] Specifically, the first cavity 211 can serve as a quantitative cavity, and the second cavity 212 can be a transfer bin. Axially, when the bottle body 1 is placed upright, a through hole is formed in the wall surface at the bottom side of the first cavity 211, the communicating pipe 23 is arranged in the through hole, and small bones are arranged in the through hole so that the communicating pipe 23 is fixedly assembled in the through hole. In addition, the communicating pipe 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 in the liquid storage bin 11. Thus, during the process of transferring the liquid in 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 communicating pipe 23, the excess liquid will flow into the liquid storage bin 11 through the communicating pipe 23, making the liquid in the first cavity 211 flush with the end face of the first end, so as to achieve quantitative liquid discharge in the first cavity 211. In addition, the communicating pipe 23 can also serve as an air inlet channel for the liquid storage bin 11 to maintain the air pressure balance in the liquid storage bin 11 and ensure the smooth flow of the liquid.

[0051] Further, the capacity value of the second cavity 212 needs to be greater than or equal to the capacity value of the first cavity 211. Thus, for the liquid transferred from the second cavity 212 to the first cavity 211, the liquid level in the first cavity 211 is either flush with the end face of the first end of the communicating pipe 23, or the liquid higher than the end face of the first end of the communicating pipe 23 will flow back to the liquid storage bin 11 through the communicating pipe 23. In addition, when the capacity value of the second cavity 212 is equal to the capacity value of the first cavity 211, the second cavity 212 can also serve as a quantitative cavity.

[0052] Further, in some embodiments, the communicating pipe 23 can move relative to the first cavity 211, and scales can be arranged on the communicating pipe 23. Thus, by moving the position of the communicating pipe 23, the liquid capacity from the bottom side of the first cavity 211 to the end face of the first end of the communicating pipe 23 can be changed, so as to realize the adjustable liquid discharge amount each time, that is, the liquid discharge amount can be changed, and thus multiple liquid discharge amounts can be realized through one storage bottle. When it is necessary to change the fixed liquid discharge amount, only the communicating pipe 23 needs to be moved, without replacing the storage bottle of a new specification, and there is no need to reserve multiple storage bottles at the same time, which can reduce the cost. It can be understood that in this embodiment, the quantitative liquid discharge refers to the single - time quantitative liquid discharge, rather than the quantitative liquid discharge each time.

[0053] Further, in some embodiments, the connecting tube 23 is stationary relative to the first cavity 211. The bottom side of the first cavity 211 is an open end, and an adjusting cup is provided at the open end. Thus, the actual liquid output is the liquid volume from the bottom side of the adjusting cup to the end face of the first end of the connecting tube 23. Moreover, the adjusting cup is movable relative to the first cavity 211, and a scale is provided on the adjusting cup. Thus, by adjusting the relative position of the adjusting cup and the first cavity 211, the distance from the bottom side of the adjusting cup to the end face of the first end of the connecting tube 23 can be changed, that is, the liquid output can be changed. Therefore, multiple liquid outputs can also be achieved with one storage bottle. When it is necessary to change the fixed liquid output, only the adjusting cup needs to be moved, without replacing a storage bottle of a new specification, and without storing multiple storage bottles at the same time, which can reduce costs. It can be understood that in this embodiment, the quantitative liquid output refers to the single - time quantitative liquid output, rather than the quantitative liquid output each time.

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

[0055] Specifically, when the liquid in the second cavity 212 is transferred to the first cavity 211, during the process of tilting the bottle body 1 to transfer the liquid in the first cavity 211 to the outside, since the extension dimension of the connecting tube 23 in the liquid storage bin 11 is long enough, even if part of the liquid in the liquid storage bin 11 flows towards the connecting tube 23, it will only stay in the connecting tube 23, which can prevent the liquid in the liquid storage bin 11 from flowing through the connecting tube 23 to the first cavity 211. In addition, by providing the anti - clogging section, the connecting tube 23 can be prevented from being blocked, so that the liquid above the end face of the first end of the connecting tube 23 can flow smoothly through the connecting tube 23 to the liquid storage bin 11, thereby ensuring quantification in the first cavity 211.

[0056] In some specific embodiments, the connecting tube 23 may include an air - passing cylinder passing through one end of the first cavity 211 away from the liquid outlet 2111, and a straw connected to the end of the air - passing cylinder away from the first cavity 211, which can achieve the quantitative liquid output of the first cavity 211 and also achieve air pressure balance.

[0057] It can be understood that in some embodiments, the air - passing cylinder and the straw may be integrally formed.

[0058] Further, in some embodiments, the bottle cap 3 axially protrudes with a first rib 31, and an arc - shaped protrusion 213 is provided on the side of the metering device 2 where the liquid outlet 2111 is provided, and the first rib 31 fits on the arc - shaped protrusion 213.

[0059] Specifically, the liquid outlet 2111 is the liquid outlet of the first cavity 211. The arc-shaped protrusion 213 is provided on the measuring device 2 and is close to the liquid outlet 2111 of the first cavity 211. The bottle cap 3 is connected to the measuring device 2. And, axially, when the bottle body 1 is placed upright, the protruding part in the arc-shaped protrusion 213 is located below the arc surface, and the first circumferential bone 31 is in close fit with the arc-shaped protrusion 213. In this way, the sealing performance of the connection between the bottle cap 3 and the measuring device 2 can be improved.

[0060] Furthermore, in some embodiments, the bottle cap 3 and the measuring device 2 can be threadedly connected. Exemplarily, an internal thread can be provided on the bottle cap 3 and an external thread can be provided on the measuring device 2 so that the internal thread and the external thread are connected. It can be understood that in other embodiments, the bottle cap 3 and the measuring device 2 can also be detachably connected in other ways, such as snap connection.

[0061] Furthermore, in some embodiments, the bottle body 1 and the measuring device 2 can be threadedly connected. Exemplarily, an external thread can be provided on the bottle body 1 and an internal thread can be provided on the measuring device 2 so that the internal thread and the external thread are connected. It can be understood that in other embodiments, the measuring device 2 and the bottle body 1 can also be detachably connected in other ways, such as snap connection.

[0062] Furthermore, in some embodiments, the liquid storage bottle further includes a sealing ring 4, and the sealing ring 4 is clamped between the measuring device 2 and the bottle mouth 12. By providing the sealing ring 4, the connection sealing performance 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 portion 21 and a first covering portion 24. The first cavity 211 and the second cavity 212 are formed in the main body portion 21. The first covering portion 24 is detachably connected to one side of the main body portion 21 where the liquid outlet 2111 is provided, and the first covering portion 24 is provided with an avoidance opening 243 aligned with the liquid outlet 2111.

[0064] Specifically, the measuring device 2 can be divided into a main body portion 21 and a first covering portion 24. The main body portion 21 includes a connection structure with an inner cavity connecting to an inner cavity and partially surrounding the outer side of the inner cavity. Part of the cavity wall of the inner cavity is the cavity wall of the first cavity 211, and the other part of the cavity wall is the cavity wall of the second cavity 212. An isolation wall is further provided inside the inner cavity, and the isolation wall can divide the inner cavity into a first cavity 211 and a second cavity 212. In addition, when the bottle body 1 is placed upright, the bottom side of the second cavity 212 is located above the bottom side of the first cavity 211. Moreover, the first covering portion 24 is provided on the side of the main body portion 21 where the liquid outlet 2111 is provided. That is to say, when the bottle body 1 is placed upright, the first covering portion 24 is connected to the top side of the main body portion 21. By providing an avoidance opening 243 on the first covering portion 24 that is aligned with the liquid outlet 2111, in this way, the liquid in the first cavity 211 can flow out to the outside successively through the liquid outlet 2111 and the avoidance opening 243.

[0065] Furthermore, in some specific embodiments, there is a flow-through gap communicating with the liquid storage chamber 11 between the inner side of the connection structure and the outer peripheral side of the second cavity 212. The first covering portion 24 is connected to the connection structure and covers the liquid inlet 2121 of the second cavity 212 and the flow-through gap. The first covering portion 24 and the main body portion 21 are relatively inclined to include a liquid inlet channel connecting the flow-through gap and the liquid inlet 2121, so as to realize the communication between the second cavity 212 and the liquid storage chamber 11, and also prevent the liquid in the second cavity 212 from directly flowing to the outside.

[0066] Furthermore, in some embodiments, the first covering portion 24 is provided with a first buckle bone 242, and the main body portion 21 is provided with a first buckle 215, and the first buckle 215 is connected to the first buckle bone 242. Through the cooperation of the first buckle 215 and the first buckle 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, and the second surrounding bone 214 is arranged inside 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 performance between the main body portion 21 and the first covering portion 24 can also be ensured.

[0068] Furthermore, in some specific embodiments, the first buckle bone 242 protrudes inside the first bone position 241, and the first buckle 215 protrudes from the second surrounding bone 214. In this way, the connection sealing performance between the main body portion 21 and the first covering portion 24 can be further improved.

[0069] Further, in some specific embodiments, in addition to the first bone position 241 provided on the outer peripheral side, the first covering portion 24 may also be provided with the first bone position 241 at the position where the avoidance opening 243 is provided, and the main body portion 21 is provided with the second surrounding bone 214 at the corresponding position, so that the sealing performance can be improved.

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

[0071] Further, in some embodiments, the second covering portion 25 is provided with a second buckle 216, and the inner cavity is provided with a second buckling bone 252. The second buckle 216 is clamped to the second buckling bone 252, so as to realize the assembly connection between the inner cavity of the main body portion 21 and the second covering portion 25.

[0072] Further, in some embodiments, the second covering portion 25 is provided with a second bone position 251, and the peripheral side wall of the inner cavity is arranged in the second bone position 251, so that the connection stability between the second covering portion 25 and the inner cavity of the main body portion 21 can be improved, and the sealing performance can also be ensured.

[0073] Further, in some specific embodiments, the second buckle 216 is arranged on the peripheral side wall of the inner cavity, and the second buckling bone 252 protrudes in the second bone position 251 of the second covering portion 25, so that the connection sealing performance between the inner cavity of the main body portion 21 and the second covering portion 25 can be further improved.
