Description

Technical Field

[0001] This invention relates to the field of container technology, and in particular to a liquid dispensing device and container. Background Technology

[0002] Currently, most liquid packaging bottles on the market suffer from a lack of convenience in terms of quantitative control. Traditional structures often use volume markings on the cap, requiring manual pouring to determine the usage amount. This type of structure is not only cumbersome, requiring users to precisely observe the markings each time they pour, but it is also prone to dosage errors or spillage, negatively impacting the user experience.

[0003] Another common type of structure is the pump head bottle, which delivers liquid through the pump head. Although it has a certain quantitative function, the amount pumped out at one time is limited. When a large amount of liquid needs to be used, it often needs to be pressed repeatedly, resulting in low efficiency. In addition, the pump head structure is easily affected by factors such as liquid viscosity and rebound force, resulting in poor stability. Summary of the Invention

[0004] The main objective of this invention is to provide a liquid dispensing device and container to at least solve the technical problems mentioned in the related art.

[0005] To achieve the above objectives, a first aspect of the present invention provides a liquid dispensing device, comprising a bottle body and a metering reservoir mounted on the bottle body; The quantitative storage cylinder has a transfer chamber and a quantitative chamber. The transfer chamber is provided with an inlet and an outlet. The inlet is connected to the cavity of the bottle body, and the outlet is connected to the quantitative chamber. The transfer warehouse is equipped with a liquid level response control component; The liquid level response control component is used to selectively block the liquid outlet, so that the liquid in the cavity passes through the transfer chamber and the metering chamber in sequence, and outputs a preset volume of liquid.

[0006] A second aspect of the present invention provides a container, including a container body and a liquid dispensing device as described in the first aspect, the liquid dispensing device being disposed within the container body.

[0007] The liquid dispensing device and container of the present invention include a bottle body and a quantitative storage cylinder. The quantitative storage cylinder is provided with a transfer chamber and a quantitative chamber. By setting a liquid level response control component in the transfer chamber, automatic quantitative control of liquid is realized during the pouring process. The accurate dispensing volume can be obtained without having to pour the liquid into the bottle cap to observe the scale, which simplifies the operation process and improves the ease of use. Compared with the traditional pump head structure, this device seals the liquid outlet hole through the liquid level trigger control component in the transfer chamber to ensure a constant output volume each time. Moreover, the dispensing volume can be set according to usage habits, avoiding cumbersome operation or quantitative errors caused by multiple presses, which significantly improves the quantitative accuracy and usage efficiency.

Any technical solution described by the above terms in the embodiments of this application should not be construed as being more preferred or advantageous than other technical solutions. Specifically, these terms are intended to present the relevant technical concepts in terms of specific implementation methods.

[0016] To address at least one technical problem in the relevant technology, such as difficulty in controlling dosage, large error in dispensing volume, and cumbersome operation, please refer to [link / reference needed]. Figures 1 to 5 This application provides a liquid dispensing device 100, which includes a bottle body 1 and a quantitative liquid storage cylinder 3 installed on the bottle body 1.

[0017] Specifically, the metering reservoir 3 comprises a transfer chamber 31 and a metering chamber 32. The transfer chamber 31 is provided with an inlet 11 and an outlet 12. The inlet 11 communicates with the cavity 10 of the bottle body 1, and the outlet 12 communicates with the metering chamber 32. Optionally, the inlet 11 and the outlet 12 are arranged on opposite sides, for example, the inlet 11 is near the top, and the outlet is near the bottom.

[0018] In this embodiment, a liquid level response control component 5 is provided inside the transfer chamber 31. This component can be a float or similar device that can move up and down with changes in liquid level. For example, when liquid in the cavity 10 of the bottle 1 enters the transfer chamber 31 through the inlet 11 (i.e., when the liquid level in the transfer chamber 31 rises), the liquid level response control component 5 (float) floats up with the rising liquid level and blocks the outlet 12 (at this time, the transfer chamber 31 is full of liquid). When the liquid level in the transfer chamber 31 drops, the liquid level response control component 5 (float) moves away from the outlet 12 due to buoyancy, thus restoring the outlet 12 to open, and the liquid in the transfer chamber 31 flows into the metering chamber 32. That is, the float can move up and down according to changes in liquid level, thereby selectively blocking the outlet 12, so that the liquid in the cavity 10 passes through the transfer chamber 31 and the metering chamber 32 in sequence, and outputs a preset volume (metered quantity) of liquid from the outlet 13 of the bottle 1.

[0019] In practical operation, the operator can control the quantitative dispensing by changing the "placement state" (positioning posture) of the dispensing device 100. For example, when the dispensing device 100 is in a tilted or inverted state (i.e., the bottle opening 102 of the bottle body 1 is facing down), liquid flows into the transfer chamber 31 from the inlet 11, the liquid level rises, and the liquid level response control component 5 floats up and, when it reaches the set liquid level, it comes into contact with the spherical cap surface at the upper end of the dispensing hole 12, thereby blocking the dispensing hole 12 and preventing the liquid in the bottle from continuing to flow into the quantitative chamber 32, thus achieving flow interruption control. When the bottle body 1 returns to the vertical or upright state (i.e., the bottle opening 102 of the bottle body 1 is facing up), the liquid level response control component 5 rises due to buoyancy, releasing the blockage of the dispensing hole 12 and reconnecting the transfer chamber 31 and the quantitative chamber 32. At this time, the liquid in the transfer chamber 31 enters the quantitative chamber 32 through the dispensing hole 12 and completes one quantitative dispensing storage.

[0020] In one optional embodiment, the preset capacity (quantitative quantity) may be approximately equal to or less than the volume of the quantitative container 32, and may be adjusted according to the actual situation.

[0021] As can be seen, the liquid dispensing device of this application embodiment, by setting a liquid level response control component in the transfer chamber, realizes automatic quantitative control of liquid during the pouring process. It can obtain an accurate dispensing volume without having to pour it into the bottle cap to observe the scale, which simplifies the operation process and improves the ease of use. Compared with the traditional pump head structure, this device seals the liquid outlet hole through the liquid level trigger control component in the transfer chamber, ensuring a constant output volume each time. It avoids cumbersome operation or quantitative errors caused by multiple presses, and significantly improves the quantitative accuracy and usage efficiency.

[0022] Please see Figures 6 to 9 The liquid dispensing device 100 also includes liquid dispensing volume control components (2, 4).

[0023] Specifically, the liquid output control component is installed on the quantitative liquid storage cylinder 3 to control the liquid output from the liquid outlet 13. For example, In an optional embodiment, the liquid output control component includes an adjusting rod 2 and a bottom cover 4. The adjusting rod 2 is provided with an overflow groove 203 extending axially. The overflow groove 203 cooperates with an air cylinder 404 provided on the bottom cover 4. The bottom cover 4 is fixed on the quantitative liquid storage cylinder 3.

[0024] In practice, by adjusting the axial position of the adjusting rod 2, the relative height of the overflow trough 203 is changed, thereby setting the effective volume of the metering chamber 32, thus achieving the preset and control of different liquid output volumes. For example, when the liquid level in the metering chamber 32 is higher than the bottom of the overflow trough 203, the overflowing liquid enters the air cylinder 404 through the overflow trough 203 and flows back to the cavity 10 of the bottle body 100, thereby adjusting the liquid output volume.

[0025] Please see Figure 10 The radial dimension of the bottom of the metering chamber 32 near the outlet 12 is larger than the diameter of the level response control component 5 (float). Therefore, one side of the bottom wall of the metering chamber 32 can form a lateral movement gap J with the level response control component 5 (float), allowing it to shift moderately within the transfer chamber in a non-blocked state. This helps maintain internal pressure balance between the transfer chamber and the metering chamber, preventing liquid flow obstruction due to pressure difference. Simultaneously, this lateral movement gap J also facilitates the smooth flow of liquid exceeding the set dispensing volume through the overflow groove on the adjusting rod into the bottom cover air cylinder, and then back into the bottle body through the venting assembly, effectively preventing excessive dispensing and improving the metering accuracy and operational stability of the device.

[0026] Please see Figures 11 to 12 The liquid dispensing device 100 also includes an inner cover 6.

[0027] Specifically, the inner cover 6 is fixedly installed on the quantitative liquid storage cylinder 3 and is provided with multiple marking structures 605.

[0028] The marking structure 605 can be a capacity scale mark set on the outer surface of the inner cover 6, used to visually indicate the liquid dispensing volume. Each marking structure corresponds to a different position of the adjusting rod 2 in the axial direction. The user can intuitively judge the currently set liquid dispensing volume based on the alignment relationship between the top of the adjusting rod 2 and the marking structure 605, realizing the visualization and precise adjustment of the liquid dispensing setting.

[0029] Please return and continue reading. Figure 9 The liquid discharge device 100 also includes a ventilation component 9.

[0030] Specifically, the ventilation component 9 can be a structure such as a straw, which is mainly set on the bottom cover 4 and has a dual function: on the one hand, the ventilation component 9 is used to guide the outside gas into the bottle body 1, thereby achieving the balance of the air pressure inside and outside the bottle and ensuring a smooth liquid dispensing process; on the other hand, when the liquid in the metering chamber 32 exceeds the set liquid level, the excess liquid can enter the air cylinder 404 through the overflow groove 203 on the adjusting rod 2, and flow back to the cavity 10 of the bottle body 1 through the ventilation component 9, so as to achieve metered liquid dispensing while avoiding excessive liquid dispensing.

[0031] Please see Figure 13 The dispensing device also includes a bottle cap 7, which can be closed onto the inner cap 6.

[0032] Specifically, the inner side of the bottle cap 7 is provided with a ring of small ribs 702, which are adapted to the top slope 603 of the inner cap 6 to enhance the sealing effect between the bottle cap 7 and the inner cap 6 and prevent liquid from evaporating or leaking.

[0033] In addition, the inner surface of the bottle cap 7 is provided with an internal thread 701, and the outer surface of the inner cap 6 is provided with an external thread 606 that matches it. The two are screwed together to make the bottle cap 7 detachable and fixed, which makes it convenient for users to close the liquid dispensing device after use or open the bottle cap when adding liquid again.

[0034] In an optional embodiment of this application, the components of the liquid dispensing device 100 achieve a stable connection and effective sealing through a multi-component mating structure, as described below with reference to the accompanying drawings: like Figure 4 and Figure 5 As shown, the bottle body 1 has an external thread 101 at the bottle mouth, and the bottom of the quantitative liquid storage cylinder 3 has an internal thread 301 that matches it, for securely installing the entire quantitative liquid dispensing device onto the bottle body 1. The head of the quantitative liquid storage cylinder 3 has a buckle 302 that fits tightly with the buckle 601 on the inner cover 6, thereby limiting and fixing the inner cover 6 in the axial direction.

[0035] like Figure 5 , Figure 11 and Figure 12 As shown, the transfer compartment and the top periphery of the metering compartment of the metering reservoir 3 are provided with a surrounding bone 303, and the inner cover 6 is provided with a small bone 602 at the corresponding position. The two work together to form a sealing structure. In addition, the outer wall of the metering reservoir 3 is also provided with a ring of small bones 304 for fixing the optional sealing ring (e.g., O-ring), which works with the inner side of the bottle mouth 102 to further enhance the overall sealing performance.

[0036] like Figure 5 and Figure 6As shown, the bottom of the quantitative liquid storage cylinder 3 is also provided with a first circular rib 306, which cooperates with the snap-fit ​​structure 401 on the bottom cover 4 to ensure that the bottom cover 4 is firmly fixed to the lower part of the liquid storage cylinder 3. The bottom cover 4 is also provided with a full-circle rib 402, which cooperates with the inner wall 307 of the quantitative chamber to form a sealed contact.

[0037] In addition, a small rib 308 is provided inside the transfer chamber 31 to limit the axial movement of the liquid level response control components (such as the float 5) and ensure the accuracy of the float control. A second circular rib 305 is provided around the liquid outlet at the bottom of the transfer chamber, making the outlet higher than the bottom surface. This helps the float 5 fit more tightly with the outlet while preserving the float's effective buoyancy area. A concave spherical cap surface 309 is also provided inside the transfer chamber to guide the float's lateral movement and achieve accurate positioning.

[0038] Optionally, the bottom cover 4 is provided with a ring of small bottom cover bones 403 for fixing the ventilation components (such as the straw 9). An air cylinder 404 is also provided on the bottom cover, the upper end of which cooperates with the sealing bone 201 at the bottom of the adjusting rod 2 to form a sealed interface for the liquid outlet path.

[0039] like Figure 7 and Figure 8 As shown, the adjusting rod 2 is also provided with a recessed step 202, which cooperates with the snap-fit ​​604 on the inner cover 6 for axial correction of the adjusting rod during assembly. The top of the air cylinder 404 is also provided with a guide bone 405 for guiding the insertion of the adjusting rod 2.

[0040] like Figure 11 , Figure 12 and Figure 13 As shown, the inner side of the bottle cap 7 is provided with a ring of small bones 702, which cooperate with the inclined surface 603 provided on the top of the inner cap 6 to form a top sealing structure to prevent external air or dust from entering the metering liquid storage cylinder.

[0041] Please see Figures 14 to 17 The figure shows the liquid discharge process of the liquid discharge device 100 in an embodiment of this application.

[0042] like Figure 14 As shown, when the bottle is tilted, the liquid inside begins to flow into the transfer chamber of the metering reservoir 3. As the liquid gradually fills the transfer chamber, the liquid level rises, and the float rises with it due to buoyancy, eventually blocking the outlet at the bottom of the transfer chamber, thus preventing the liquid from continuing to flow into the metering chamber and achieving automatic flow interruption.

[0043] like Figure 15As shown, when the bottle returns to its upright position, the float continues to rise under buoyancy. However, because the liquid level in the transfer chamber drops at this time, the float breaks free from the seal on the outlet, and the transfer chamber reconnects with the metering chamber. The liquid that has been filled into the transfer chamber begins to flow into the metering chamber. At the same time, excess liquid exceeding the capacity of the transfer chamber flows back into the bottle, ensuring that only the liquid in the metering chamber is retained for the next dispensing.

[0044] like Figure 16 As shown, as the liquid 200 in the transfer chamber enters the metering chamber, when the liquid level in the metering chamber is higher than the lower port of the overflow tank, the excess liquid will enter the air cylinder through the overflow tank and flow back into the bottle through the suction tube, thereby realizing automatic liquid volume adjustment and internal pressure balance.

[0045] like Figure 17 As shown, when the bottle is tilted again, the liquid in the metering chamber flows out from the outlet, achieving a single metered dispensing. Simultaneously, new liquid flows into the transfer chamber, initiating the next metered cycle. That is, the contents of the metering chamber flow out each time the bottle is tilted, while the contents of the bottle flow into the transfer chamber of the storage cylinder, thus repeating the cycle to ensure that the amount poured each time is the pre-set capacity.

[0046] This application also provides a container, including a container body and a liquid dispensing device 100 as described in the above embodiments, wherein the liquid dispensing device 100 is disposed within the container body.

[0047] The liquid dispensing device and container of this application embodiment include a bottle body and a quantitative storage cylinder. The quantitative storage cylinder is equipped with a transfer chamber and a quantitative chamber. By setting a liquid level response control component in the transfer chamber, automatic quantitative control of liquid is realized during the pouring process. The accurate dispensing volume can be obtained without having to pour the liquid into the bottle cap to observe the scale, which simplifies the operation process and improves the ease of use. Compared with the traditional pump head structure, this device seals the liquid outlet hole through the liquid level trigger control component in the transfer chamber, ensuring a constant output volume each time. This avoids cumbersome operation or quantitative errors caused by multiple presses, and significantly improves the quantitative accuracy and usage efficiency.

[0048] The specific embodiments of the invention have been described in detail above, but these are merely examples, and the invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the invention are also within the scope of this invention. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of this invention should be covered within the scope of this invention.
