Description

[Technical Field]

[0001] The present invention relates to a liquid dispensing device for dispensing liquids. Specifically, the present invention allows a user to select whether to dispense a first liquid or to mix a first liquid with a second liquid, as desired. More specifically, the present invention allows a user to adjust and mix the concentrations of the first liquid and the second liquid to be mixed. [Background technology]

[0002] Consumers are increasingly interested in and desire unique and engaging experiences associated with beverages. They are not simply consuming beverages for their taste or functionality. Taking beverage bottles as an example, individuals often need energy drinks to supplement their energy during exercise. These energy drinks are typically prepared by diluting concentrates. However, most beverage bottles on the market can only accommodate a single type of beverage. As a result, when these bottles are filled with energy drinks, they cannot simultaneously hold another beverage, such as water. This inconvenience forces users to carry an additional beverage bottle specifically for water. Taking beverage machines as an example, beverage machines are versatile devices designed to accommodate water and various concentrates to prepare beverages with different flavors. Conventional beverage dispensers available on the market allow for the mixing of different liquids, but often lack the ability to modify the concentration of individual ingredients.

[0003] To address these issues and provide an alternative solution, the present invention introduces a liquid dispensing device that can be assembled into a bottle, thereby containing at least two liquids, or that can be used with a beverage machine. Users can select the desired type of liquid they need, providing enhanced convenience. Furthermore, the present invention allows these liquids to be mixed during consumption, providing an additional benefit. Most notably, the present invention allows users to control the concentration of the mixed liquid during drinking, further enhancing the user experience. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention will now be presented by way of example in the following paragraphs with reference to the drawings. Objects, features, and aspects of the present disclosure will be disclosed in or will be apparent from the following description. It will be understood by those skilled in the art that the following description is merely a description of exemplary embodiments and does not limit the broader aspects of the present disclosure, which are embodied in the exemplary configurations.

[0035] It should be noted that unless otherwise specified, technical or scientific terms used in the embodiments of the present invention shall have the ordinary meanings understood by those skilled in the art to which the present invention belongs. The terms "first," "second," and similar expressions used in the embodiments of the present invention do not indicate order, quantity, or importance, but are used only to distinguish different components. Furthermore, terms indicating directions, such as "front," "rear," "left," "right," "upper," and "lower," are used only for describing examples of relative positional relationships shown in the drawings to facilitate understanding. The disclosed components of the present invention are not limited to being able to adhere to only this specific relative positional relationship. Terms such as "connecting, etc.", "attaching, etc.", "fixing, etc.", or "assembling, etc." are not limited to physical or mechanical connection, whether direct or indirect.

[0036] FIG. 1 shows a bottle designated by reference numeral 100. Bottle 100 comprises a base member 102, a lid member 104, and a lid cover 106. In FIG. 1, it can be seen that a utility portion 108 extending vertically outward beyond lid cover 106 allows a user to drink the liquid contained within bottle 100. Although utility portion 108 extends vertically and outward beyond lid cover 106, it can be appreciated that those skilled in the art can directly and clearly understand that utility portion 108 need not extend vertically and outward beyond lid cover 106. Depending on the user's requirements for bottle 100, utility portion 108 can be designed and / or configured to be hidden / stored under lid cover 106 or even disassembled using commonly known means, thus obscuring its visibility and preventing utility portion 108 from becoming contaminated.

[0037] In the context of the present invention, it should be understood that when the lid member 104 is assembled to the base member 102, it indicates that the lid member 104 is on or above the base member 102, and allows for a general understanding of terms such as "up and down," "up and down," "left and right," "front and back," "up and down," "horizontal, vertical / perpendicular," "high and low," etc., which are used in this context to indicate relative directions or positions, the definitions of which are equivalent to the spatial arrangement shown in the figures in the direction towards the sheet of the figures.

[0038] The cross section of the lid member 104 is sized and shaped to correspond to the cross section of the base member 102, and thus the lid member 104 is assembled onto the base member 102 by common closure means, such as a screw closure or quick fit, as are well known in the art. For the sake of brevity, closure means are well understood by those skilled in the art and therefore will not be described in detail herein.

[0039] 2 shows the bottle 100 without being covered by the lid cover 106. FIG. 3 shows a cross-sectional view of the base member 102. The peripheral wall and bottom of the base member 102 define a cavity that allows the base member 102 to contain a first liquid. The first liquid is, for example, water. It should be understood that the base member 102 also refers to a first container.

[0040] 4 shows a cross-sectional view of the lid member 104. It can be seen that the lid member 104 is configured to be recessed downwardly from its surface 104A to form a receptacle 114. By definition, "recessed downwardly from its surface to define a receptacle" in the context of the present invention refers to configuring the lid member 104 to provide the receptacle 114 formed below the surface 104A of the lid member 104. It can be seen that the surface 104A of the lid member 104 has an aperture 116 adjacent to the receptacle 114 to allow the utility part 108 to pass therethrough.

[0041] 5, the bottle 100 includes a second container 200. The second container 200 includes a second lid cover 202 and a second base member 204. As can be seen from the figure, an outlet 206 for the second container 200 is provided on the outward upper surface of the second lid cover 202.

[0042] The peripheral wall and bottom of the second base member 204 define a cavity, as shown in FIG. 6 . In one embodiment, the cavity is configured to accommodate a pouch of liquid, such as, for example, fruit juice or a sports drink. It should be appreciated that liquid pouches are readily available for purchase at convenience stores, and thus, a user can choose to fill the second container 200 with different flavors of fruit juice or sports drink. Different packages other than in the form of a pouch are also suitable for use with the second container 200 according to the present invention. In another embodiment, the cavity is configured to accommodate a liquid, such as fruit juice or a sports drink. In this embodiment, a user can pour the fruit juice or sports drink directly into the second container 200.

[0043] It should be understood that these embodiments are for illustrative purposes only and should not be construed as limitations on the second container 200 for containing fruit juice or sports drinks, collectively understood as a second liquid that may optionally be different from the above-mentioned first liquid contained in the base member 102.

[0044] After the second base member 204 is filled with the second liquid, the second base member 204 is closed and sealed with the second lid cover 202 .

[0045] FIG. 7 shows the assembly of the drinking member 112 and the second container 200 to the closure member 104. It can be seen that the liquid dispensing device of the present invention is part of the closure assembly for the bottle. An O-shaped gasket 122, also known as a closure rubber ring, is disposed on the inner periphery of the closure member 104. For simplicity, the second container 200 is empty in FIG. 7. The drinking member 112 is defined by the assembly between the utility portion 108 and the straw 110. As can be seen from FIG. 7, the utility portion 108 is provided with an outlet 138 for a user to draw liquid or beverage and a first inlet 128 opposite the outlet 138. A pressure valve 120 is provided adjacent to the first inlet 128.

[0046] 7, the utility portion 108 further comprises a second inlet 118 in fluid communication with the utility portion 108. In one embodiment, the second inlet 118 is configured as a protrusion extending outwardly away from the body of the utility portion 108. FIG. 8 shows an enlarged view of the utility portion 108 with the second inlet 118.

[0047] Figure 9 shows a cross-sectional view of a drinking member 112 according to one embodiment of the present invention. Figure 9 shows that the utility portion 108 includes a pressure valve 120 adjacent to the first inlet 128 and positioned between the utility portion 108 and the straw 110 of Figure 9. The valve 120 in this embodiment is provided with a cross-shaped slit. The location and configuration of the pressure valve 120 in Figure 9 is for illustrative purposes only and should not be understood as a limitation on the use of the valve 120 when practicing the present invention.

[0048] In one illustrative embodiment, the drinking member 112 is provided with a valve 120 characterized by a valve opening pressure of 5 kPa. This means that while a user is using the outlet 138 of the utility portion 108 of the drinking member 112 to draw water in the base member 102, when the pressure drop in the utility portion 108 begins to exceed 5 kPa, i.e., when the pressure difference between the pressure in the utility portion 108 and the pressure in the straw 110 begins to exceed 5 kPa, the water in the base member 102 will begin to be drawn upward by the straw 110, defining a first passageway for water to flow from the base member 102 to the outlet 138 of the utility portion 108.

[0049] It should be understood that the opening pressure of 5 kPa in this embodiment is for illustrative purposes only, and that the opening pressure of the valve can be modified or changed according to actual needs using common means in the art. For brevity, common means for modifying or changing the opening pressure of the valve will not be described in detail herein. An advantage of the valve 120 is that it can ensure that water flows out of the base member 102 only until the pressure difference between the pressure inside the utility portion 108 and the pressure inside the straw 110 reaches a certain level due to the suction effect generated by the user.

[0050] 10 shows the assembly of the drinking member 112 and second container 200 to the lid member 104, the drinking member 112 and second container 200 being connected by a tube 304. By way of example, the second container 200 comprises a pouch of fruit juice 300. In this embodiment, it can be seen that the outlet 206 of the pouch of fruit juice 300 and the drinking nozzle 302 are connected to each other in fluid communication, which can be achieved, for example, by inserting a tube / straw between the drinking nozzle 302 and the outlet 206.

[0051] FIG. 11 shows an exploded view of the embodiment of FIG.

[0052] 12 illustrates an embodiment in which the second inlet 118 of the utility portion 108 and the outlet 206 of the second container in which the juice pouch is disposed are selectively fluidly connected with a tube 400, preferably made of silicone. As shown, the outlet 206 and the drinking nozzle of the juice pouch are interconnected in fluid communication, for example, using a tube / straw therebetween. It should be understood that the tube 400 is merely an example, and that direct or indirect fluid connection between the first container and the second container can be achieved by any conventional means.

[0053] When a user aspirates water from the base member 102, for example, using the utility portion 108 of the drinking member 112, which is provided with the valve 120 as described above. From the above description, it should be understood that the body of the utility portion 108 and the valve 120 together define a cavity within the utility portion 108. As the user aspirates water at the outlet 138 of the utility portion 108, the pressure within the cavity decreases. Using the valve 120 as an example, once the pressure drop within the utility portion 108 begins to exceed 5 kPa, the water within the base member 102 begins to be rapidly drawn upward by the straw 110 toward the utility portion 108. This rapid upward movement of water through the utility portion 108 creates a Venturi effect at the second inlet 118, thus reducing the pressure at the second inlet 118. The Venturi effect then draws the juice upward out of the second container 200, then through the tube 400 and into the utility section 108 via the second inlet 118, which defines a second passageway. Within the utility section 108, the juice meets the water, which causes the water and juice to mix in the utility section 108.

[0054] From the above, it should be understood that the liquid dispensing apparatus according to the present invention comprises a utility part 108 in fluid communication with a first liquid contained in a base member 102 (first container), and a second container 200 in which a second liquid is stored is in fluid communication with a drinking member 112. The operation of the liquid dispensing apparatus is as described above.

[0055] The liquid dispensing device can also be used without a straw connected to the utility portion 108. In this way, when the liquid dispensing device of the present invention is assembled to a container, it functions like a baby bottle when in use. In other words, when the liquid dispensing device operates in this way, the liquid dispensing device shown in Figures 1-12 is upside down. In some embodiments, the liquid dispensing device can also be used in a beverage machine, which will be further described in the following context.

[0056] Advantageously, the liquid dispensing device comprises regulating means 500 configured to operatively affect the volumetric flow rate in the second passage between the second inlet 118 and the outlet 206. It should be understood that the present invention can be practiced without the regulating means 500. In one embodiment, the regulating means 500 is shown at different angles in Figures 13A-C. As shown, the regulating means 500 in this embodiment is configured in the form of a T-shaped button 600 having a leg 614 extending downwardly from a surface 612 thereof. The leg 614 is provided with a through opening 616 that transverses the longitudinal axis of the leg 614. In one embodiment, the through opening 616 allows a tube to pass therethrough, the tube connecting the second inlet 118 and the outlet 206.

[0057] Figure 14A shows an exploded view of an embodiment provided with adjustment means according to Figures 13A-C. As can be seen, the embodiment of Figure 14A is provided with a buffer tank 618 comprising a channel 620 and an aperture 622. The channel 620 connects the second inlet 118 and the outlet 206.

[0058] FIG. 14B shows the T-shaped button 600 positioned to be inserted into the aperture 622 of the buffer tank 618 and further illustrates the location of the gaskets 122 and 124, with the gasket 124, also referred to as the top cover ring, positioned inside the periphery of the lid cover 106.

[0059] 15A-C are schematic diagrams illustrating the state of the channel 620 of the buffer tank 618 when the T-shaped button 600 is in use, particularly when it is rotated. FIG. 15A illustrates that the T-shaped button 600 is configured to be partially exposed above the lid cover 106, allowing a user to rotate the T-shaped button 600 to control the orientation of the through-opening 616 and, consequently, the internal tubular cavity of the channel 620. FIG. 15B corresponds to the T-shaped button 600 in the "closed" state shown in FIG. 15A, and FIG. 15C corresponds to the T-shaped button 600 in the "maximum" state shown in FIG. 15A. When the T-shaped button 600 is in the "closed" state, the channel 620 is blocked as shown in FIG. 15B. Therefore, it can be assumed that juice cannot be delivered to the utility portion 108 even if a Venturi effect occurs. By gradually rotating the T-shaped button 600, for example, counterclockwise from 0 to 90 degrees, the through opening 616 also gradually rotates counterclockwise from 0 to 90 degrees, thereby gradually opening the channel 620 compared to the state in FIG. 15B during the rotation of the T-shaped button 600. When the T-shaped button 600 is undergoing a rotational movement, the internal tubular cavity of the channel 620 gradually increases with the rotational movement starting gradually from 0 to 90 degrees.

[0060] 16-17 show that the adjustment means 500 is a wedge-shaped member 700 arranged adjacent to the tube 400, particularly longitudinally relative to the elongated profile of the drinking member 112. The wedge-shaped member 700 comprises a handle 702 and a sloped slot 704 corresponding to the sloped profile of the wedge-shaped member 700. FIG. 18 shows a cross-sectional view of a liquid dispensing device of the present invention provided with an adjustment means 500 in the form of a wedge-shaped member 700. With reference to FIGS. 16 and 18, it will be appreciated that by sliding the handle 702 downward within the slot 704, the handle 702 begins to push against the tube 400 (which in this embodiment is arranged vertically to connect the second inlet 118 and the outlet 206), thereby reducing the diameter of the tube and therefore the volume of juice flowing towards the utility portion 108 during the Venturi effect. It should be appreciated that the further down the handle 702 advances, the further the interior tubular cavity of the tube 400 decreases. It should also be appreciated that the wedge member 700 can be positioned in any position as long as it affects the tube 400, as described below.

[0061] In one embodiment, the adjusting means 500 is a tuning or rotating knob with an eccentric cylindrical profile positioned adjacent to, and in particular on, the tube 400. By rotating / turning the knob around its rotation axis, the cylindrical profile of the knob squeezes / compresses the tube 400, thus reducing the tube's diameter. Therefore, during the Venturi effect, the volume of juice flowing toward the utility part 108 is reduced. Because the knob has an eccentric cylindrical profile, it can be assumed that the edge farthest from the rotation axis exerts the greatest pressure on the tube 400, i.e., the tube's internal tubular volume is minimized. In contrast, the edge closest to the rotation axis exerts the least pressure on the tube 400, i.e., the tube's internal tubular volume is maximized. In yet another embodiment, the adjusting means 500 can be configured to completely capture / grasp the tubing 400, so that juice cannot pass through the tube 400 and reach the utility part 108, even with the Venturi effect. In this embodiment, only water is consumed by the user.

[0062] It should be understood that the above-described embodiments of the adjusting means 500 are merely examples. Other mechanical structures capable of adjusting the flow of the second liquid from the second container are also within the scope of the present invention. In other words, the operation of the adjusting means 500 is not limited by reducing only the internal tubular cavity of the tube 400.

[0063] The liquid dispensing device allows a user to choose to drink the first liquid or mix the first liquid with a second liquid as needed. More specifically, the liquid dispensing device allows a user to adjust and mix the concentrations of the first liquid and the second liquid to be mixed.

[0064] It will be appreciated that the liquid dispensing device according to the present invention may be manufactured integrally with the closure member for manufacturing purposes.

[0065] 19A-B show variations of the bottle 100 embodiment configured with different positions of the receptacle 114. Although the position of the second container 200 in FIGS. 19A-B is different, these embodiments still function with the above description without departing from the spirit of the present invention. In the embodiment of FIG. 19A, it may be envisioned that a portion of the peripheral wall of the base member 102 may be open to allow a user to place or remove a juice pack. In the embodiment of FIG. 19B, it may also be envisioned that a portion of the bottom of the base member 102 may be open to allow a user to place or remove a juice pack. With reference to FIGS. 19A-B, it should be understood that the utility portion of the present invention may be configured as part of a lid assembly assembled to a bottle.

[0066] However, it should be understood that the liquid dispensing device of the present invention can be manufactured and used independently without the need for a lid member, providing users with the convenience of using the liquid dispensing device of the present invention with different containers, such as bottles, mugs, and glasses. The embodiment of Figures 19C-D without the lid member 104 can be used to practice the present invention. The lid member 104 described herein is not a limitation of the present invention.

[0067] 20 is a perspective cross-sectional view of another embodiment of the liquid dispensing device of the present invention. The utility portion of the liquid dispensing device is part of a lid assembly 800. The lid assembly 800 includes a pressure valve 802, a valve mounting member 804, a mixing member 806, a lid member 808, an adjustment member 810, a second container 812, a ring member 814, and an outlet 816.

[0068] In one embodiment, silicone rubber, especially elastic silicone rubber, is suitable for preparing the valve 802 or the valve attachment member 804 or the mixing member 806 .

[0069] 21A-21C show pressure valve 802 in different views, with FIG. 21A being a top view, FIG. 21B being a bottom perspective view, and FIG. 21C being a bottom view. Similar to valve 120 described above, pressure valve 802 features a cross-shaped valve with an opening pressure of 5 kPa. Thus, operation of pressure valve 802 refers to operation of valve 120 as described above.

[0070] 22A-22C show different views of the valve mounting member 804, with FIG. 22A being a top perspective view, FIG. 22B being a bottom perspective view, and FIG. 22C being a bottom view. An internal cavity in the form of a central aperture 804A at the top of the valve mounting member 804 is sized and designed to receive and seat the pressure valve 802 therein, as shown in FIG.

[0071] 23A-23E show different views of mixing element 806, with FIG. 23A being a top perspective view, FIG. 23B being a bottom perspective view, FIG. 23C being a side view, FIG. 23D being a top view, and FIG. 23E being a bottom view. Mixing element 806 has an upper portion sized to provide a cavity and a lower portion configured to provide a receptacle 806A. Receptacle 806A is sized and designed to receive valve mounting element 804 with pressure valve 802, as shown in FIG. 20. For example, a first engagement element 806B is provided within receptacle 806A. By engaging, e.g., press-fitting, the engagement member 804B (FIG. 22A) of the valve mounting member 804 with the first engagement member 806B of the mixing member 806, the valve mounting member 804 is removably secured within the receptacle 806A, as shown in FIG. 20.

[0072] FIGS. 24A-24C show different views of the cover member 808, with FIG. 24A being a top view, FIG. 24B being a bottom view, and FIG. 24C being a bottom perspective view. As shown in FIG. 24A, the cover member 808 has a central aperture 808A, a first groove 808B, and a second groove 808C for removably receiving the outlet 816. The grooves 808B and 808C are arranged opposite each other and form a sickle shape. The first groove 808B has a first end 808B-1 and a second end 808B-2. The second groove 808C has a first end 808C-1 and a second end 808C-2. The first end 808B-1 has an aperture 808D, which is a second entrance for the utility portion of the present invention. FIG. 24C shows that a recess 808E is provided in the internal cavity of the cover member 808. It is important to note that a portion of recess 808E below central aperture 808A is first inlet 808F of the utility portion of the present invention. For clarity, please refer to the dotted circle in FIG. 24C as first inlet 808F. Those skilled in the art will understand that the locations and shapes of grooves 808B and 808C and aperture 808D in FIG. 24 are merely illustrative examples and do not impose any limitations on the disclosed invention. In some embodiments, outlet 816 and lid member 808 are integrally formed.

[0073] 25A and 25B, it can be seen that the size and shape of the recess 808E are suitable for accommodating the mixing element 806, for example, by press-fitting the mixing element 806 into the recess 808E, whereby the second engagement member 806C of the mixing element 806 abuts the wall of the recess 808E. Figure 25C shows that a buffer tank 818, preferably made of silicone rubber, more preferably elastic silicone rubber, is located within the first groove 808B.

[0074] 26A-26D show buffer tank 818 in different views, with FIG. 26A being a top perspective view, FIG. 26B being a bottom perspective view, FIG. 26C being a top view, and FIG. 26D being a cross-sectional view.

[0075] 26A shows that the upper surface of the buffer tank 818 is provided with a groove 818A having a sickle-shaped profile and having a first end 818B and a second end 818C, and the width of the groove is designed to narrow from the first end 818B to the second end 818C. A first opening 818D is provided in the first end 818B. Furthermore, it can be seen that the depth of the groove is designed to decrease from the first end 818B to the second end 818C. Those skilled in the art will understand that the profile of the groove 818A shown in FIG. 26 is merely an example and can be modified according to actual needs when using the present invention.

[0076] Figure 26B shows that the buffer tank 818 includes legs 818E with a second opening 818F at its bottom. The first opening 818D (at the first end 818B) and the second opening 818F define a channel 818G, as shown in Figure 26D. It should be understood that the channel 818G and the mixing element 806 are in fluid communication.

[0077] 24A, 25C, and 26B, it can be seen that the legs 818E of the buffer tank 818 are inserted into the apertures 808D of the lid member 808, and thus the buffer tank 818 is removably secured and received in the first grooves 808B of the lid member 808. Preferably, as shown in FIG. 26B, the legs 818E are provided with enlarged heads that are slightly larger than the apertures 808D, so that the buffer tank 818 can be prevented from easily coming off the lid member 808, for example, by press-fitting the enlarged heads into the apertures 808D. Preferably, the buffer tank 818 includes an engagement member 818H on its periphery to facilitate installation of the buffer tank 818 in the first grooves 808B of the lid member 808.

[0078] 27A and 27B show the assembly between the pressure valve 802, valve mounting member 804, mixing member 806, lid member 808, outlet 816, and buffer tank 818. These figures show that there is a gap between the legs 818E of the buffer tank 818 and the cavity of the mixing member 806. It should be understood that the outlet 816, mixing chamber 806, and buffer tank 818 can be in fluid communication.

[0079] It should be understood that the assembly of FIG. 27 (also FIG. 20 ) can be assembled to / on a base member, e.g., base member 102, in which the first liquid (water) is contained. For simplicity, FIG. 27 does not show the base member. It should be understood that the base member, pressure valve 802, valve mounting member 804, mixing member 806, and outlet 816 can be fluidly connected. If desired, as shown in FIGS. 1-19 , a straw, e.g., straw 110, can be connected to the first inlet of the utility portion using commonly known means. In this embodiment, the straw with the utility portion defines a drinking member, as described above. It should be understood that in FIGS. 20-27 , the configuration of the utility portion body, mixing member 806, and pressure valve 802 together define a cavity. Using the drinking member, the user draws on the first liquid (stored in the first container) which passes upward through the pressure valve 802, reducing the pressure within the cavity and thus creating a Venturi effect which occurs adjacent the second opening 818F.

[0080] 28A-28D show adjustment member 810 in different views, with FIG. 28A being a top perspective view, FIG. 28B being a bottom perspective view, FIG. 28C being a top view, and FIG. 28D being a side view. Adjustment member 810 is provided with a first aperture 810A located in the center, a second aperture 810B, and a protrusion 810C. The position of aperture 810B and protrusion 810C are arranged opposite each other. It should be understood that the positions, number, and shapes of aperture 810B and protrusion 810C are merely examples.

[0081] 29A-C show the assembly of the adjustment member 810 onto the cover member 808. Components such as the buffer tank 818, the second groove 808C of the cover member 808, and the protrusion 810C of the adjustment member 810, which would not be visible in FIGS. 29A-C, are shown here with dotted lines for easier understanding. As shown, the protrusion 810C is disposed in the second groove 808C of the cover member 808, and the second aperture 810B is disposed above the buffer tank 818.

[0082] Specifically, FIG. 29A shows that the adjustment member 810 is assembled to the lid member 808 by passing the first aperture 810A through the outlet 816, the protrusion 810C is received in the second groove 808C of the lid member 808, and the second aperture 810B is positioned over the buffer tank 818 assembled to the first groove 808B of the lid member 808.

[0083] 29B-C, it should be understood that, after assembly with the lid member 808, the adjustment member 810 is configured to rotate circularly around the outlet 816 within a specific range or range limited by the allowable movement of the protrusion 810C of the adjustment member 810 within the second groove 808C. In other words, the range or range is limited by the length of the second groove 808C. In FIG. 29B, it can be seen that when the protrusion 810C of the adjustment member 810 is moved to the second end 808C-2 of the lid member 808, the second aperture 810B overlaps the first opening 818D of the buffer tank 818. In FIG. 29B, both the second aperture 810B and the first opening 818D are exposed.

[0084] 29B-29C, when adjustment member 810 moves clockwise around outlet 816 from the state of FIG. 29B to the other state of FIG. 29C, it can be seen that protrusion 810C is at first end 808C-1 of cover member 808 and second aperture 810B is at second end 818C of buffer tank 818. In other words, first opening 818D of buffer tank 818 is not visible and is covered by adjustment member 810 (the appearance of first opening 818D in FIG. 29C is for illustrative purposes only).

[0085] 30A-30C show the second container 812 in different views, with FIG. 30A being a top perspective view, FIG. 30B being a bottom perspective view, and FIG. 30C being a side view.

[0086] Optionally, the second container is disposable. The second container has a central aperture 812A and a pair of engaging members 812B surrounding the central aperture 812A. As shown in the figure, the pair of engaging members 812B are arranged opposite each other. A protrusion 812C having an opening through which the second liquid (fruit juice) can flow out is provided on the bottom side of the second container. As with the second container 200 described above, the description of the second container 200 is referred to for the description of the second container 812.

[0087] 31A-31C show different views of ring member 814, with FIG. 31A being a top perspective view, FIG. 31B being a bottom perspective view, and FIG. 31C being a top view.

[0088] Ring member 814 has a central aperture 814A that allows outlet 816 to pass through. Gripping members 814B are provided around the periphery of ring member 814 to facilitate a user rotating ring member 814 around outlet 816 to attach and detach ring member 814 from outlet 816.

[0089] The inner circumference of ring member 814 is provided with threads or threaded members that mate with threads or threaded members on outlet 816 (see FIGS. 20, 25, and 27). These threads or threaded members between ring member 814 and outlet 816 attach ring member 814 to outlet 816, and when central aperture 814A passes through outlet 816, ring member 814 may be configured to be threaded upward by threading in one direction and downward by threading in another direction, thereby securing ring member 814 in a fixed position around outlet 816.

[0090] FIG. 32A is a perspective view of the assembly between the ring member 814 and the second container 812, and FIG. 32B is a cross-sectional view of the assembly between the ring member 814 and the second container 812. FIG. 32 shows the assembly between the ring member 814 and the second container 812 by a snap fit between the pair of engagement members 812B of the second container 812 and the engagement member 814C of the ring member 814. It can be seen that there is a separation between the peripheral wall of the ring member 814 and the inner wall of the second container 812, and thus the second container can be configured to rotate around the ring member 814 while the ring member 814 remains fixed. In other words, the second container 812 can be configured to move independently of the ring member 814.

[0091] 33 shows an exploded view of the lid assembly 800, which includes a mixing member 806, a lid member 808, an adjustment member 810, a second container 812, a ring member 814, an outlet 816, and a buffer tank 818. For assembly of the mixing member 806, the lid member 808, the adjustment member 810, the outlet 816, and the buffer tank 818, please refer to the above description.

[0092] With regard to assembling the second container 812 around the ring member 814 (two views in FIG. 32) and the outlet 816, this is achieved by first positioning the protrusion 812C of the second container 812 over the second aperture 810B of the adjustment member 810. Then, the second container 812 with the ring member 814 (shown in FIG. 32) is screwed downwardly, for example, around the outlet 816, using the respective threads or threaded members provided on the ring member 814 and the outlet 816, as described above.

[0093] Preferably, one embodiment has a first configuration defined by the opening of the protrusion 812C of the second container 812 over the first opening 818D of the buffer tank 818, whereby the volumetric flow rate of juice is maximized from the second container 812 to the first opening 818D of the buffer tank 818 because the opening of the protrusion 812C of the second container coincides with the first opening 818D of the buffer tank 818, thus maximizing the volumetric flow rate therebetween. An embodiment has a second configuration defined by the opening in the protrusion 812C of the second container 812 on the second end 818C of the buffer tank 818, whereby the volumetric flow rate of juice from the second container 812 to the buffer tank 818 is minimized because the opening in the protrusion 812C of the second container is abutted by the second end 818C of the buffer tank 818. More preferably, the second configuration can be configured such that the second end 818C of the buffer tank 818 essentially seals the opening in the protrusion 812C of the second container, thereby preventing essentially any juice from flowing from the second container 812 to the buffer tank 818.

[0094] When the lid assembly 800 is used, a user can connect the utility portion together with a straw to define a drinking member (as described above) and assemble the lid assembly 800 (together with the straw) to a bottle (first container) in which water is stored. When a user aspirates water from within the bottle (not shown), for example using a drinking member provided with a valve 802 as described above, once the pressure drop within the utility portion begins to exceed 5 kPa, the water within the container begins to be drawn rapidly upward by the straw of the drinking member (not shown) towards the outlet 816. Such rapid upward movement of water through the utility portion 108 creates a Venturi effect at the second inlet of the utility portion 806, thus reducing the pressure at the second inlet of the utility portion.

[0095] Then, due to the Venturi effect, the juice in the second container 812 is drawn downward, exits the second container 812, passes through the opening in the protrusion 812C, then passes through the second aperture 810B of the adjustment member 810, and reaches the buffer tank 818 via the first opening 818D. The juice then flows from the buffer tank 818 to the mixing chamber 806 via a channel 818G defined by the first opening 818D (second end 818C) and the second opening 818F of the buffer tank 818. In the mixing chamber 806, the juice mixes with the water drawn in by the user. The mixture of water and juice is thus transported to the outlet 816 and then consumed by the user.

[0096] The lid assembly 800 can also be used without a straw connected to the outlet 816. In this manner, when the lid assembly 800 is assembled to a first container, it functions like a baby bottle when the lid assembly 800 is in use. In other words, when the lid assembly 800 functions in this manner, the lid assembly 800 shown in Figures 20 and 33 is upside down.

[0097] The lid assembly 800 is also provided with an adjusting means for adjusting the concentration of the first liquid to be mixed with the second liquid to be mixed. The adjusting means can be realized by using an adjusting member 810 in cooperation with at least a buffer tank 818.

[0098] With reference to the above, and particularly to Figures 26-29, one skilled in the art can appreciate that the mixing between the water and juice in the mixing chamber depends on the amount of juice flowing into the mixing chamber when the Venturi effect occurs.

[0099] In a first situation, when the position of the opening in the protrusion 812C of the second container 812 is directly above the first opening 818D (at the first end 818B) of the buffer tank 818, it can be understood that the fluid path (defined by the opening in the protrusion 812C of the second container 812 and the channel 818G of the buffer tank 818) is fully established or enabled. In the first situation, the amount of juice flowing into the mixing chamber 806 is greatest when the Venturi effect occurs. In a second situation, when the position of the opening in the protrusion 812C of the second container 812 is directly above the second end 818C of the buffer tank 818, it can also be understood that the fluid path (defined by the opening in the protrusion 812C of the second container 812 and the channel 818G of the buffer tank 818) is blocked or disabled. In the second situation, the amount of juice flowing into the mixing chamber 806 is least when the Venturi effect occurs. In the second situation, in some embodiments, depending on the design of the lid assembly 800, when the Venturi effect occurs, zero juice flows into the mixing chamber 806.

[0100] Specifically, taking the diagrams of Figures 29B-C as an example, the fluid pathway in Figure 29B is fully established or enabled, whereas the fluid pathway in Figure 29C is blocked or disabled.

[0101] From the above description, it should be appreciated that a user can selectively adjust the amount of juice flowing into and mixing within the mixing chamber 806 by circularly rotating the second container 812 or the adjustment member 810, or both, around the outlet 816 in a clockwise or counterclockwise direction, depending on the actual design of the lid assembly 800.

[0102] From the above, it should be understood that the liquid dispensing device according to the present invention comprises a utility part in fluid communication with a first liquid contained in a base member (first container), and a second container in which a second liquid is stored is in fluid communication with the utility part. The operation of the liquid dispensing device is as described above.

[0103] Those skilled in the art should understand that the disclosed adjustments or adjustment mechanisms are merely examples and should not be construed as limitations on the scope of the present invention. As long as a user can adjust the amount of juice flowing from the second container to mix with the first liquid during the Venturi effect, it is within the scope of the present invention. In particular, as long as a user can adjust the fluid communication between the first container and the second container by the adjustment mechanism, especially during the Venturi effect, it is within the scope of the present invention.

[0104] 34 is a perspective cross-sectional view of a lid assembly 900, which is a variation of the lid assembly 800. In the following context, only the differences between the lid assemblies 800 and 900 will be described.

[0105] Figure 35 shows a vent 920 with different views: Figure 35A is a top perspective view, Figure 35B is a bottom perspective view, and Figure 35C is a side view. Optionally, the vent 920 is an umbrella valve with a diaphragm-shaped sealing disk that allows one-way flow while preventing backflow. Such vents are commonly known in the art, and therefore, this specification will not describe them in detail.

[0106] Figure 36 shows, in different views, a lid member 908, which is a variation of lid member 808. Figure 36A is a perspective top view, Figure 36B is a perspective bottom view, and Figure 36C is a bottom view. What differs from lid member 808 is a recess 908F for accommodating air vent 920.

[0107] Figure 37 shows the mixing chamber 906 in different views, with Figure 37A being a top perspective view and Figure 37B being a bottom perspective view. The mixing chamber 906 is provided with a pair of wings 906A to facilitate the user in removing the mixing chamber 906 from the lid member 908.

[0108] Figure 38 shows an adjustment member 910, which is a variation of adjustment member 810, in different views. Figure 38A is a perspective top view, and Figure 38B is a perspective bottom view. With reference to Figures 34 and 38, it can be seen that the periphery of adjustment member 910 is exposed to the outside after adjustment member 910 is assembled to lid member 908. A serpentine-shaped periphery 910A of adjustment member 910 makes it easy for a user to rotate adjustment member 910 around the spout.

[0109] Figure 39 shows different views of a second container 912, which is a variation of second container member 812.

[0111] 44 is a schematic diagram illustrating the operation of a beverage dispenser equipped with a liquid dispensing apparatus according to the present invention. The beverage dispenser is designed to cater to a wide range of beverage preferences. Specifically, it allows users the flexibility to choose between consuming a standalone first liquid or choosing a mixture of the first liquid and a second liquid based on their individual needs and desires. Furthermore, the beverage dispenser allows users to precisely adjust the concentration of both the first and second liquids that are mixed together.

[0112] The beverage dispenser in this embodiment comprises several essential components, including a body having a dispenser outlet, a water tank (acting as a first container for a first liquid), a nanofilter, an electric pump, a cartridge reservoir (acting as a second container for a second liquid), and a liquid dispensing device according to the present invention. These components are intelligently interconnected electrically and fluidically to ensure seamless operation, as shown in FIG. 44. Importantly, the beverage dispenser includes a control panel. Preferably, the cartridge reservoir is disposable or replaceable, providing the advantage of preventing bacterial growth within the beverage dispenser. Preferably, the tubing connecting the electric pump and the water tank is also replaceable, providing the same advantage of preventing bacterial growth within the beverage dispenser.

[0113] In some embodiments, the dispensing outlet is a specially designed nozzle that allows for the release of both the first liquid and / or the second liquid while allowing for the desired mixing. This means that the user can conveniently select and enjoy their preferred combination of liquids, whether water, energy drink, or other flavor options available in the dispenser, particularly the cartridge reservoir. Preferably, the nozzle is disposable or replaceable, which offers the advantage of preventing bacterial growth within the beverage dispenser.

[0114] The water tank as the main container holds the water supply for the dispenser, ensuring a steady source of clean, fresh water. To enhance the quality of the dispensed beverage, a nanofilter is incorporated into the system. This specialized filter effectively removes impurities and contaminants, ensuring a purer and healthier drinking experience. Preferably, the nanofilter filters the water before it enters the liquid dispensing device.

[0115] The nanofilter, a key component of beverage dispensers, is designed with advanced filtering capabilities to ensure the highest quality of dispensed beverages. It incorporates nanofiber and / or activated carbon materials, preferably arranged in a rod-like configuration. This novel design maximizes the filtering efficiency and effectiveness of the nanofilter.

[0116] The primary function of a nanofilter is to remove various contaminants from the water or other liquids used in the dispenser. It is specifically designed to meet stringent quality standards such as NSF 42 requirements by effectively removing chlorine, taste, and odor.

[0117] This ensures that the dispensed beverage is free of objectionable flavors and odors, as well as meeting desired taste expectations.

[0118] In addition to removing taste and odor, nanofilters are excellent at removing heavy metals, meeting NSF53 requirements. Heavy metals known for their potentially harmful effects are efficiently filtered, protecting the health and well-being of consumers. This feature is particularly beneficial for individuals concerned about the presence of contaminants in their drinking water or beverages.

[0119] Furthermore, the nanofilter exhibits superior performance in removing bacteria and viruses, achieving a remarkable 99% removal rate. This high level of filtration ensures that dispensed beverages are safe and free of harmful microorganisms, providing peace of mind to users.

[0120] By combining the filtering capabilities of nanofiber and activated carbon materials, the nanofilter provides comprehensive purification of the liquid passing through it. It acts as a reliable barrier, trapping impurities and ensuring only clean, high-quality water or liquid reaches the final beverage. This advanced filtration technology improves the overall taste, purity, and safety of the dispensed beverage, making it a desirable choice for consumers seeking a premium drinking experience.

[0121] Electric pumps play a vital role in beverage dispensers, facilitating the smooth flow and delivery of the desired beverage. They efficiently transfer filtered water or other liquid from a water tank or cartridge reservoir to a dispensing outlet, ensuring a consistent and controlled dispensing process.

[0122] The beverage dispenser is provided with a control panel. Referring to the schematic diagram 1, it should be understood that the control panel can control the electric pump.

[0123] In some embodiments, a control panel can operate all components within the beverage dispenser. This interface allows the user to adjust settings, select desired beverage options, control the dispensing process, and monitor the overall operation of the dispenser. The control panel enhances user convenience and ensures a user-centric experience.

[0124] The cartridge reservoir, which functions as a secondary container, provides a convenient space for storing additional ingredients or flavors. This allows users to easily add various cartridges containing flavor concentrates, dietary supplements, or other liquid enhancers. By incorporating these cartridges, the beverage dispenser offers a wide range of beverage options that can be customized to suit individual preferences. Preferably, these cartridges are disposable or reusable, providing flexibility to accommodate different tastes and requirements.

[0125] The liquid dispensing device is designed to include a cavity having three essential components: a first inlet, a second inlet, and an outlet. The operation of the liquid dispensing device is the same as that described above. The first inlet establishes a fluid connection with the water tank and is also connected to the outlet of the liquid dispensing device. When water flows from the water tank to the outlet of the liquid dispensing device, it establishes a first passageway. Meanwhile, the second inlet is fluidly connected to a cartridge reservoir, which is in turn connected to a cartridge containing a flavor concentrate, dietary supplement, or other liquid enhancer. Furthermore, the second inlet is also fluidly connected to the outlet of the liquid dispensing device. When the contents flow from the cartridge to the outlet of the liquid dispensing device, it establishes a second passageway. The outlet of the liquid dispensing device is directly connected to the dispensing outlet. The operation of the liquid dispensing device proceeds as follows: When the electric pump is activated to pump water from the water tank toward the dispensing outlet, the high velocity of the water in the liquid dispensing device induces a Venturi effect at the second inlet. As a result, the pressure at the second inlet decreases. This effect allows the contents of the cartridge to be drawn and transported from the cartridge toward the liquid dispensing device through the second inlet. Once inside the liquid dispensing device, the contents of the cartridge come into contact with the flowing water and begin to mix. This process allows the contents to thoroughly mix and integrate with the water. As a result, the water and the desired liquid, such as fruit juice, are effectively combined and mixed within the liquid dispensing device. It is important to note that the strength of the Venturi effect is directly affected by the power or strength of the electric pump. Preferably, the liquid dispensing device is disposable or replaceable, providing the advantage of preventing bacterial growth within the beverage dispenser.

[0126] In certain embodiments, the beverage dispenser is characterized by a configuration in which the liquid dispensing device, cartridge reservoir, and nanofilter are housed within the body of the dispenser. This arrangement ensures a compact and simplified design. The water tank is located externally, providing easy access for refilling purposes. It is important to note that the location of these components may vary depending on specific requirements and design considerations. The actual location and configuration of the cartridge reservoir, nanofilter, and water tank is determined based on actual needs, allowing for flexibility and optimization in the overall design of the beverage dispenser.

[0127] The beverage dispenser may be equipped with various features to enhance functionality and control the liquid being dispensed, such as a push button that acts as a start and stop control allowing the user to start and stop the dispensing process as desired.

[0128] Additionally, the dispenser features a rotary dial that provides precise control over the blending of concentrates between the first and second liquids. By adjusting the dial, users can fine-tune the blend ratio or strength according to their personal preferences. This level of control allows users to create customized beverages with the exact balance of flavor and strength they desire. It's worth emphasizing that the rotary dial plays a key role in influencing the Venturi effect that occurs at the second inlet of the liquid dispensing device. This is achieved by controlling the volumetric flow rate of the contents from the cartridge to the liquid dispensing device. By adjusting the rotary dial, users can adjust the amount of contents drawn from the cartridge toward the liquid dispensing device. This, in turn, affects the intensity of the Venturi effect created at the second inlet. The ability to control the Venturi effect via the rotary dial provides users with greater flexibility when customizing beverages.

[0129] The combination of push buttons and rotary dials allows users to effortlessly dispense and customize their beverage to suit their taste preferences. Whether it's a refreshing mix of water and flavoring, an invigorating blend of sports drink concentrate and water, or any other desired combination, the beverage dispenser provides a user-centric experience that allows for convenient, personalized, and adjustable liquid dispensing.
