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 to dispense a first liquid or a mixture between the first liquid and a second liquid according to their needs. More specifically, the present invention allows a user to adjust the concentrations of the first liquid to be mixed and the second liquid to be mixed for mixing. Background Art

[0002] Consumers' interest and expectations for unique and attractive experiences related to beverages are growing. Beverages are not just consumed for their taste or function. Take a drinking bottle as an example. During exercise, individuals often need energy drinks to replenish their physical strength. These energy drinks are usually prepared by diluting concentrates. However, most drinking bottles on the market can only hold a single type of beverage. Thus, when these bottles are filled with energy drinks, they cannot hold another beverage, such as water, at the same time. This inconvenience forces users to carry an additional drinking bottle specifically for holding water. Take a beverage machine as an example. It is a multi-functional device designed to hold water and multiple concentrates for preparing different flavored beverages. Conventional beverage dispensers available on the market, although allowing the mixing of different liquids, generally lack the ability to change the concentration of each component.

[0003] To address these problems and provide alternative solutions, the present invention proposes a liquid dispensing device that can be assembled into a bottle, thereby being able to hold at least two liquids; or can be used in a beverage machine. The user can select the desired type of liquid they need, thus providing enhanced convenience. In addition, the present invention allows the mixing of these liquids during consumption, thereby providing an additional advantage. Most notably, the present invention enables the user to control the concentration of the mixed liquid during consumption, thereby further enhancing their experience. Summary of the Invention

[0087] The present invention will now be presented by way of example with reference to the accompanying drawings in the following paragraphs. The objectives, features, and aspects of the present disclosure are disclosed or are obvious from the following description. Those of ordinary skill in the art should understand that the following description is only a description of exemplary embodiments and is not intended to limit the broader aspects of the present disclosure, which are embodied in the exemplary configurations.

[0088] It should be noted that unless otherwise defined, technical terms or scientific terms used in the embodiments of the present invention should have the ordinary meaning understood by those of ordinary skill in the art to which the present invention pertains. The terms "first", "second", and similar expressions used in the embodiments of the present invention do not indicate any order, quantity, or importance, but are only used to distinguish different components. Terms such as "front", "rear", "left", "right", "upper", and "lower" and other terms indicating orientation or similar terms are only described for the exemplary relative positional relationships shown in the drawings for ease of understanding. This does not limit the components disclosed in the present invention to only follow such specific relative positional relationships. "Connection", etc., "installation", etc., or "fixation", etc., or "assembly", etc. are not limited to direct or indirect physical or mechanical connections.

[0089] Figure 1Shows a bottle denoted by reference numeral 100. The bottle 100 includes a base member 102, a lid member 104, and a lid cover 106. In Figure 1 As can be seen, the utility portion 108 that extends vertically and outwardly beyond the lid cover 106 allows a user to drink the liquid contained in the bottle 100. It will be understood that although the utility portion 108 extends vertically and outwardly beyond the lid cover 106, those skilled in the art can directly and clearly understand that the utility portion 108 does not necessarily need to extend vertically and outwardly beyond the lid cover 106. Depending on the needs of the user for the bottle 100, the utility portion 108 can be designed and / or configured to be hidden / stored under the lid cover 106, or even removable, and thus invisible, by common well-known means, thereby preventing the utility portion 108 from being contaminated.

[0090] It should be understood that in the context of the present invention, when the lid member 104 is assembled to the base member 102, it indicates that the lid member 104 is on top of or above the base member 102, thus allowing the general understanding of terms such as "up and down", "above and below", "left and right", "front and back", "top and bottom", "horizontal, vertical / vertically", "high and low" to be used in this context to express relative directions or positions, the definitions of which are equivalent to the spatial arrangement in the direction of entry into the drawing sheet as shown in the drawings.

[0091] The dimensions and shape of the cross-section of the lid member 104 are set to correspond to the cross-section of the base member 102, so the lid member 104 is assembled on top of the base member 102 by common closing means well-known in the art such as screw closing or snap fitting. For the sake of brevity, the closing means are well-known to those skilled in the art and are not explained in detail herein.

[0092] Figure 2 Shows the bottle 100 not covered by the lid cover 106. Figure 3 Shows a cross-sectional view of the base member 102. The circumferential 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 the first container.

[0093] Figure 4 Represents 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 receiver 114. By definition, in the context of the present invention, "recessed downwardly from its surface to define a receiver" means that the lid member 104 is configured to provide a receiver 114 formed below the surface 104A of the lid member 104. It can be seen that the surface 104A of the lid member 104 is provided with a hole 116 that is adjacent to the receiver 114, thereby allowing the utility portion 108 to pass therethrough.

[0094] As Figure 5 shown, the bottle 100 has a second container 200. The second container 200 includes a second lid covering 202 and a second base member 204. As can be seen, an outward-facing top surface of the second lid covering 202 is provided with an outlet 206 for the second container 200.

[0095] As Figure 6 shown, a circumferential wall and a bottom of the second base member 204 define a cavity. In one embodiment, the cavity is configured to accommodate, for example, a pouch of liquid such as fruit juice or a sports drink. It should be understood that the pouch of liquid can be readily purchased at a convenience store, so that a user can choose to place different flavors of fruit juice or sports drinks in the second container 200. Different packages other than the pouch form are also suitable for 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.

[0096] It should be understood that these embodiments are for illustrative purposes only and should not be construed as a limitation on the second container 200 to accommodate fruit juice or a sports drink generally understood as a second liquid, which may optionally be different from the first liquid contained in the base member 102 as described above.

[0097] After filling the second base member 204 with the second liquid, the second base member 204 is closed and sealed with the second lid covering 202.

[0098] Figure 7 An assembly of the drinking member 112 and the second container 200 to the lid member 104 is shown. It can be seen that the liquid dispensing device of the present invention is part of a lid assembly of a bottle. An O-ring 122, also referred to as a lid rubber ring, is disposed internally around a circumference of the lid member 104. For the sake of brevity, Figure 7 the second container 200 in Figure 7 is empty. The drinking member 112 is defined by an assembly between a utility portion 108 and a straw 110. As can be seen in

[0099] still in Figure 7 the utility portion 108 is provided with an outlet 138 for a user to suck a liquid or a beverage, and a first inlet 128 opposite to the outlet 138. A pressure valve 120 is disposed adjacent to the first inlet 128. Figure 8 A close-up view of the utility portion 108 having the second inlet 118 is shown.

[0100] Figure 9 A cross-sectional view of the drinking member 112 according to an embodiment of the present invention is shown. It shows that the utility portion 108 is provided with a pressure valve 120, which is adjacent to the first inlet 128 and is Figure 9 positioned between the utility portion 108 and the straw 110. The valve 120 in this embodiment is provided with a cross-shaped slit. Figure 9 The position and configuration of the pressure valve 120 in are for illustrative purposes only and should not be construed as a limitation on the use of the valve 120 when implementing the present invention.

[0101] In an embodiment for illustrative purposes, the drinking member 112 is provided with a valve 120, characterized in that the valve opening pressure is 5 kPa. This means that during the user sucking water in the base member 102 through the outlet 138 of the utility portion 108 of the drinking member 112, when the pressure drop in the utility portion 108 starts to exceed 5 kPa, that is, when the pressure difference between the pressure in the utility portion 108 and the pressure in the straw 110 starts to exceed 5 kPa, the water in the base member 102 starts to be sucked upward by the straw 110, thereby defining a first passage for the water to flow from the base member 102 to the outlet 138 of the utility portion 108.

[0102] It should be understood that the opening pressure of 5 kPa in this embodiment is for illustrative purposes only, and it should also be understood that the opening pressure of the valve can be modified or changed according to actual needs by using common means in the art. For the sake of brevity, the common means for modifying or changing the valve opening pressure are not explained in detail herein. The advantage of the valve 120 is that it can ensure that the water flows out of the base member 102 only when the pressure difference between the pressure in the utility portion 108 and the pressure in the straw 110 reaches a certain level due to the suction action generated by the user.

[0103] Figure 10 The assembly of the drinking member 112 and the second container 200 to the cover member 104 is shown, wherein the drinking member 112 and the second container 200 are connected by a tube 304. For illustration, the second container 200 is provided with a juice bag 300. In this embodiment, it can be seen that the outlet 206 and the drinking mouth 302 of the juice bag 300 are connected in a fluidly communicable relationship, which can be achieved, for example, by inserting a tube / straw between the drinking mouth 302 and the outlet 206.

[0104] Figure 11 Shows Figure 1 an exploded view of the embodiment in.

[0105] Figure 12An embodiment is shown in which the second inlet 118 of the utility portion 108 and the outlet 206 of the second container for holding the juice bag are selectively fluidly connected by a tube 400 preferably made of silicone. As shown, the outlet 206 and the drinking spout of the juice bag are connected to each other in a relationship that allows for fluid communication, for example, with a tube / straw therebetween. It should be understood that the tube 400 is merely an example, and the direct or indirect fluid connection between the first container and the second container can be achieved by any conventional means.

[0106] When the user sucks water in the base member 102 with the utility portion 108 of the drinking member 112, the drinking member is provided with a valve 120 as described above. For 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. When the user sucks water at the outlet 138 of the utility portion 108, the pressure in the cavity decreases. Taking the valve 120 as an example, when the pressure drop within the utility portion 108 begins to exceed 5 kPa, the water in the base member 102 begins to be rapidly and upwardly sucked by the straw 110 towards the utility portion 108. This rapid upward movement of water through the utility portion 108 causes a Venturi effect at the second inlet 118, and thus the pressure at the second inlet 118 decreases. Due to the Venturi effect, the juice is then sucked upward out of the second container 200 and then passes through the tube 400 to reach the utility portion 108 via the second inlet 118, thereby defining a second passageway. Inside the utility portion 108, the juice meets the water. Thus, the water and the juice are mixed in the utility portion 108.

[0107] For the above, it should be understood that the liquid dispensing device according to the present invention includes a utility portion 108 that is in fluid communication with a first liquid contained in a base member 102 (first container); a second container 200 for storing a second liquid is in fluid communication with the drinking member 112. The operation of the liquid dispensing device involves the above.

[0108] The liquid dispensing device can also be used without using a straw connected to the utility portion 108. Thus, when the liquid dispensing device of the present invention is assembled to a container, it works like a baby bottle when the liquid dispensing device is used. In other words, when the liquid dispensing device works in this way, Figures 1 to 12 the liquid dispensing device shown is upside down. In some embodiments, the liquid dispensing device can also be used in a beverage machine, which will be further explained below.

[0109] Advantageously, the liquid dispensing device is provided with an adjusting device 500. The adjusting device is configured to operatively act on the volume 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 implemented without the adjusting device 500. In one embodiment, the adjusting device 500 is shown at different angles in Figures 13A to 13C As shown, the adjusting device 500 in this embodiment is configured in the form of a T-shaped button 600, which has a leg 614 extending downward from its surface 612. The leg 614 is provided with a through opening 616 extending through the longitudinal axis of the leg 614. In one embodiment, the through opening 616 allows a tube to pass through, and the tube connects the second inlet 118 and the outlet 206.

[0110] Figure 14A An exploded view of an embodiment of the adjusting device provided according to Figures 13A to 13C is shown. As can be seen, Figure 14A the embodiment in is provided with a buffer tank 618, which includes a passage 620 and a hole 622. The passage 620 connects the second inlet 118 and the outlet 206.

[0111] Figure 14B It is shown that the T-shaped button 600 is arranged to be inserted into the hole 622 of the buffer tank 618, and the positions of the gaskets 122 and 124 are also shown, where the gasket 124 (also known as the top cover ring) is arranged inside around the circumference of the cover 106.

[0112] Figures 15A to 15C is a schematic diagram showing the state of the passage 620 of the buffer tank 618 when the T-shaped button 600 is in use, especially during rotation. Figure 15A It is shown that the T-shaped button 600 is configured to be partially exposed on the cover 106, so that the user can rotate the T-shaped button 600 to control the orientation of the through opening 616, so as to control the internal tubular cavity of the passage 620. Figure 15B corresponds to Figure 15A the T-shaped button 600 shown in in the "closed" state, while Figure 15C corresponds to Figure 15A the T-shaped button 600 shown in in the "maximum" state. It can be envisaged that when the T-shaped button 600 is in the "closed state", the passage 620 is blocked, as shown in Figure 15B , so that even if the Venturi effect occurs, the juice is not allowed to be delivered to the utility part 108. By gradually rotating the T-shaped button 600, for example, gradually rotating counterclockwise from 0 degrees to 90 degrees, the through opening 616 also gradually rotates counterclockwise from 0 degrees to 90 degrees, thereby corresponding to Figure 15BCompared with the state in [reference], channel 620 gradually opens during the rotation of the T-shaped button 600. When the T-shaped button 600 rotates, the internal tubular cavity of channel 620 increases gradually from 0 degrees to 90 degrees with the rotation movement.

[0113] In one embodiment, Figures 16 to 17 the adjustment device 500 is shown as a wedge member 700, which is arranged adjacent to the tube 400, particularly longitudinally with respect to the elongated profile of the drinking member 112. The wedge member 700 is provided with a handle 702 and a slot 704, which is inclined corresponding to the inclined profile of the wedge member 700. Figure 18 A cross-sectional view of the liquid dispensing device of the present invention is shown, which is provided with an adjustment device 500 in the form of a wedge member 700. Refer to Figure 16 and Figure 18 , it should be understood that by sliding the handle 702 downward in the slot 704, the handle 702 begins to press against the tube 400 (in this embodiment, the tube 400 is arranged to vertically connect the second inlet 118 and the outlet 206), whereby the diameter of the tube decreases, and thus during the Venturi effect, the volume of juice flowing to the utility section 108 decreases. It should be understood that as the handle 702 moves further downward, the internal tubular cavity of the tube 400 further decreases. It should also be understood that the wedge member 700 can be arranged at any position as long as it affects the tube 400, as described below.

[0114] In one embodiment, the adjustment device 500 is an adjustment knob or a rotary knob with an eccentric cylindrical profile, which is arranged adjacent to the tube 400, particularly on it. By rotating the knob around its axis of rotation, the cylindrical profile of the knob squeezes / compresses the tube 400 and thus the diameter of the tube decreases. Therefore, during the Venturi effect, the volume of juice flowing to the utility section 108 decreases. Since the knob has an eccentric cylindrical profile, it can be envisaged that the edge farthest from the axis of rotation exerts the maximum pressure on the tube 400, i.e., the internal tubular volume of the tube becomes the smallest. On the contrary, the edge closest to the axis of rotation exerts the minimum pressure on the tube 400, i.e., the internal tubular volume of the tube becomes the largest. In another embodiment, the adjustment device 500 can be configured to completely jam / grip the tube 400, and thus even in the presence of the Venturi effect, juice is not allowed to pass through the tube 400 to reach the utility section 108. In this embodiment, the user only drinks water.

[0115] It should be understood that the embodiments of the adjustment device 500 described above are only examples. Mechanical structures that can adjust the flow of the second liquid from the second container other than those described above also fall within the scope of the present invention. In other words, the operation of the adjustment device 500 is not limited to only reducing the internal tubular cavity of the tube 400.

[0116] The liquid dispensing device allows the user to select to drink the first liquid or a mixture between the first liquid and the second liquid according to their needs. More specifically, the liquid dispensing device allows the user to adjust the concentrations of the first liquid to be mixed and the second liquid to be mixed for mixing.

[0117] It should be understood that the liquid dispensing device according to the present invention can be integrally manufactured with the lid member for manufacturing purposes.

[0118] Figures 19A to 19B A variant of an embodiment of the bottle 100 configured with receivers 114 at different positions is shown. Although Figures 19A to 19B the position of the second container 200 in Figure 19A is different, these embodiments are still applicable to the above description without departing from the spirit of the present invention. It is conceivable that in Figure 19B the embodiment of Figures 19A to 19B , a part of the circumferential wall of the base member 102 can be opened to allow the user to place or remove the juice pack. It is also conceivable that in

[0119] the embodiment of Figures 19C to 19D , a part of the bottom of the base member 102 can be opened to allow the user to place or remove the juice pack. Referring to

[0120] Figure 20 is a cross-sectional perspective view showing another embodiment of the liquid dispensing device of the present invention. The functional part of the liquid dispensing device is a part of the 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 adjusting member 810, a second container 812, a ring member 814, and an outlet 816.

[0121] In one embodiment, silicone rubber, especially elastic silicone rubber, is suitable for making the valve 802 or the valve mounting member 804 or the mixing member 806.

[0122] Figures 21A to 21C The pressure valve 802 is shown in different views, where Figure 21A is a top view, Figure 21B is a perspective bottom view, and Figure 21CIt is a bottom view. Similar to the valve 120 described above, the pressure valve 802 features a cross-shaped valve with an opening pressure of 5 kPa. Therefore, as described above, the operation of the pressure valve 802 refers to the operation of the valve 120.

[0123] Figures 22A to 22C The valve mounting member 804 is shown in different views, where Figure 22A is a perspective top view, Figure 22B is a perspective bottom view, and Figure 22C is a bottom view. As Figure 20 shown, the inner cavity in the form of the central hole 804A in the upper part of the valve mounting member 804 is sized and designed to accommodate the pressure valve 802 located therein.

[0124] Figures 23A to 23E The mixing member 806 is shown in different views, where Figure 23A is a perspective top view, Figure 23B is a perspective bottom view, Figure 23C is a side view, Figure 23D is a top view, and Figure 23E is a bottom view. The mixing member 806 has an upper part sized to provide a cavity and a lower part configured to provide a receiver 806A. The receiver 806A is sized and designed to accommodate the valve mounting member 804 having the pressure valve 802, as Figure 20 shown. For example, a first engaging member 806B is provided inside the receiver 806A. By engaging (e.g., press-fitting) the engaging member 804B of the valve mounting member 804 ( Figure 22A in) with the first engaging member 806B of the mixing member 806, the valve mounting member 804 is removably fixed in the receiver 806A, as Figure 20 shown.

[0125] Figures 24A to 24C The cover member 808 is shown in different views, where Figure 24A is a top view, Figure 24B is a bottom view, Figure 24C is a perspective bottom view. As Figure 24A shown, the cover member 808 is provided with a central hole 808A for removably receiving the outlet 816, a first groove 808B, and a second groove 808C. The grooves 808B and 808C are arranged opposite to each other and are sickle-shaped. 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. At the first end 808B-1, a hole 808D is provided, which is the second inlet of the practical part of the present invention. Figure 24CThe inner cavity of the cover member 808 is shown to be provided with a recess 808E. It is important to note that a part of the recess 808E below the central hole 808A is the first inlet 808F of the practical part of the present invention. For clarity, please consider the Figure 24C dotted circle part in

[0126] as the first inlet 808F. Those skilled in the art should understand that the positions and shapes of the grooves 808B and 808C and the hole 808D in FIG. 24 are only illustrative examples and should not impose any limitations on the disclosed invention. In some embodiments, the outlet 816 and the cover member 808 are integrally formed. Figure 25A and Figure 25B , it can be seen that the size and shape of the recess 808E are adapted to accommodate the mixing member 806, for example, by press-fitting the mixing member 806 into the recess 808E, whereby the second engaging member 806C of the mixing member 806 abuts against the wall of the recess 808E. Figure 25C The buffer tank 818, preferably made of silicone rubber and more preferably made of elastic silicone rubber, is shown to be located in the first groove 808B.

[0127] Figures 26A to 26D The buffer tank 818 is shown in different views, where Figure 26A is a perspective top view, Figure 26B is a perspective bottom view, Figure 26C is a top view, and Figure 26D is a cross-sectional view.

[0128] Figure 26A The upper surface of the buffer tank 818 is shown to be provided with a groove 818A having a sickle-shaped profile with a first end 818B and a second end 818C, wherein the width of the groove is designed to narrow from the first end 818B towards the second end 818C. A first opening 818D is provided at the first end 818B. In addition, it can be seen that the depth of the groove is designed to decrease from the first end 818B towards the second end 818C. Those skilled in the art should understand that the profile of the groove 818A shown in FIG. 26 is only an example and can be modified according to actual needs when using the present invention.

[0129] Figure 26B The buffer tank 818 is shown to be provided with a leg portion 818E, with a second opening 818F provided at its bottom. The first opening 818D (at the first end 818B) and the second opening 818F define a channel 818G, as Figure 26D shown. It should be understood that the channel 818G and the mixing member 806 are capable of fluid communication.

[0130] Reference Figure 24A 、 Figure 25C and Figure 26B, it can be understood that the leg portion 818E of the buffer tank 818 is inserted into the hole 808D of the cover member 808, so that the buffer tank 818 is removably fixed and received in the first groove 808B of the cover member 808. Preferably, as Figure 26B shown, the leg portion 818E is provided with an enlarged head having a size slightly larger than the hole 808D, so that, for example, by press-fitting the enlarged head through the hole 808D, the buffer tank 818 can be prevented from easily detaching from the cover member 808. Preferably, the buffer tank 818 is provided with an engaging member 818H on its outer periphery to facilitate the installation of the buffer tank 818 into the first groove 808B of the cover member 808.

[0131] Figure 27A and Figure 27B show the assembly between the pressure valve 802, the valve mounting member 804, the mixing member 806, the cover member 808, the outlet 816 and the buffer tank 818. These figures show that there is a gap between the leg portion 818E of the buffer tank 818 and the cavity of the mixing member 806. It should be understood that the outlet 816, the mixing chamber 806 and the buffer tank 818 are in fluid communication.

[0132] It should be understood that the components in Fig. 27 (also in Figure 20 ) can be assembled onto a base member (such as the base member 102) that houses the first liquid (water). For the sake of simplicity, the base member is not shown in Fig. 27. It should be understood that the base member, the pressure valve 802, the valve mounting member 804, the mixing member 806, and the outlet 816 are in fluid communication. As Figures 1 to 1 shown in Fig. 9, if necessary, a straw (such as the straw 110) can be connected to the first inlet of the utility portion by known means. In this embodiment, the straw with the utility portion defines a drinking member, as described above. Referring to Figures 20 to 2 Fig. 7, it should be understood that the configuration of the body of the utility portion, the mixing member 806 and the pressure valve 802 together define a cavity. With the drinking member, the user sucks up the first liquid (stored in the first container) through the pressure valve 802, and the pressure in the cavity decreases, thereby generating a Venturi effect occurring adjacent to the second opening 818F.

[0133] Figures 28A to 28D The adjusting member 810 is shown in different views, where Figure 28A is a perspective top view, Figure 28B is a perspective bottom view, Figure 28C is a top view, and Figure 28D is a side view. The adjusting member 810 is provided with a first hole 810A, a second hole 810B and a protrusion 810C located at the center. The positions of the hole 810B and the protrusion 810C are arranged opposite to each other. It should be understood that the positions, numbers and shapes of the hole 810B and the protrusion 810C are only examples.

[0134] Figures 29A to 29C Shows the assembly of the adjustment member 810 on the cover member 808. For better illustration, 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 that should not be visible in Figures 29A to 29C are now shown in dashed lines. As shown, the protrusion 810C is arranged in the second groove 808C of the cover member 808, and the second hole 810B is arranged on the buffer tank 818.

[0135] Specifically, Figure 29A Shows the assembly of the adjustment member 810 to the cover member 808 by passing the first hole 810A through the outlet 816, where the protrusion 810C is received in the second groove 808C of the cover member 808, and the second hole 810B is positioned on the buffer tank 818 assembled to the first groove 808B of the cover member 808.

[0136] For Figures 29B to 29C , it should be understood that after being assembled to the cover member 808, the adjustment member 810 is configured to rotate circularly around the outlet 816 to a certain extent or within a certain range, and the extent or range is limited by the allowed movement of the protrusion 810C of the adjustment member 810 in the second groove 808C. In other words, the extent or range is limited by the length of the second groove 808C. In Figure 29B , it can be seen that when the protrusion 810C of the adjustment member 810 moves to the second end 808C-2 of the cover member 808, the second hole 810B then overlaps with the first opening 818D of the buffer tank 818. Both the second hole 810B and the first opening 818D are exposed in Figure 29B .

[0137] Still referring to Figures 29B to 29C , when the adjustment member 810 circularly moves around the outlet 816 in the clockwise direction around the outlet 816 from the state in Figure 29B to another state in Figure 29C , it can be seen that the protrusion 810C is now at the first end 808C-1 of the cover member 808, and the second hole 810B is now at the second end 818C of the buffer tank 818. In other words, the first opening 818D of the buffer tank 818 is not visible and is covered by the adjustment member 810 ( Figure 29C the appearance of the first opening 818D in

[0138] Figures 30A to 30C The second container 812 is shown in different views, where Figure 30A is a perspective top view, Figure 30B is a perspective bottom view, and Figure 30C is a side view.

[0139] Optionally, the second container is disposable. The second container is provided with a central hole 812A and a pair of engaging members 812B at the periphery of the central hole 812A. As shown, the pair of engaging members 812B are arranged opposite to each other. The bottom side of the second container is provided with a protrusion 812C having an opening that allows the second liquid (juice) to flow out. Similar to the second container 200 described above, the description of the second container 812 refers to the description of the second container 200.

[0140] Figures 31A to 31C The ring member 814 is shown in different views, where Figure 31A is a perspective top view, Figure 31B is a perspective bottom view, and Figure 31C is a top view.

[0141] The ring member 814 is provided with a central hole 814A that allows the outlet 816 to pass through. The outer periphery of the ring member 814 is provided with a clamping member 814B, thereby providing convenience for the user to rotate the ring member 814 around the outlet 816 to install or disassemble the ring member 814 from the outlet 816.

[0142] The inner periphery of the ring member 814 is provided with a thread or threaded member that is coupled to the thread or threaded member on the outlet 816 (see Figure 20 , Figures 25 and 27). By means of these threads or threaded members between the ring member 814 and the outlet 816, when the ring member 814 is installed on the outlet 816 and the central hole 814A passes through the outlet 816, the ring member 814 can be configured to be screwed upward by screwing in one direction and can be configured to be screwed downward by screwing in the other direction, whereby the ring member 814 can be fixed in place around the outlet 816.

[0143] Figure 32A is a perspective view of the assembly between the ring member 814 and the second container 812, and Figure 32B is a cross-sectional view of the assembly between the ring member 814 and the second container 812. Figure 32 shows the assembly between the ring member 814 and the second container 812 by means of the snap - fit between a pair of engaging members 812B of the second container 812 and the engaging member 814C of the ring member 814. It can be seen that there is a spacing between the peripheral wall of the ring member 814 and the inner wall of the second container 812, so that 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.

[0144] Figure 33A exploded view of the lid assembly 800 is shown, which includes a mixing member 806, a lid member 808, an adjusting member 810, a second container 812, a ring member 814, an outlet 816, and a buffer tank 818. For the assembly of the mixing member 806, the lid member 808, the adjusting member 810, the outlet 816, and the buffer tank 818, please refer to the foregoing description.

[0145] Regarding the assembly of the second container 812 and the ring member 814 (two illustrations in Figure 32) around the outlet 816, this is achieved by first positioning the protrusion 812C of the second container 812 in the second hole 810B of the adjusting member 810. Then, the second container 812 with the ring member 814 (the illustration in Figure 32) is screwed down around the outlet 816, for example, by means of corresponding threads or threaded members provided on the ring member 814 and the outlet 816, as described above.

[0146] Preferably, one embodiment has a first configuration defined by the opening at the protrusion 812C of the second container 812 on the first opening 818D of the buffer tank 818, whereby the volumetric flow rate of the juice from the second container 812 to the first opening 818D of the buffer tank 818 is maximized because the opening at the protrusion 812C of the second container coincides with the first opening 818D of the buffer tank 818, thereby maximizing the volumetric flow rate between them. The said embodiment has a second configuration defined by the opening at the protrusion 812C of the second container 812 on the second end 818C of the buffer tank 818, whereby the volumetric flow rate of the juice from the second container 812 to the buffer tank 818 is minimized because the opening at 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 to substantially seal the opening at the protrusion 812C of the second container by the second end 818C of the buffer tank 818, whereby substantially no juice flows from the second container 812 to the buffer tank 818.

[0147] When using the lid assembly 800, the user can connect the utility part to a straw, thereby defining a drinking member (as described above) and assembling the lid assembly 800 (together with the straw) to a bottle (first container) storing water. When the user sucks the water in the bottle (not shown in the figure) with the drinking member (which is provided with a valve 802 as described above), when the pressure drop in the utility part starts to exceed 5 kPa, the water in the container starts to be rapidly and upwardly sucked by the straw (not shown in the figure) of the drinking member towards the outlet 816. Such a rapid upward movement of the water through the utility part 108 causes a Venturi effect at the second inlet of the utility part 806, and thus the pressure at the second inlet of the utility part decreases.

[0148] Due to the Venturi effect, the juice in the second container 812 is then suctioned downward, exits the second container 812 through the opening at the protrusion 812C, then passes through the second hole 810B of the adjustment member 810, reaches the buffer tank 818 via the first opening 818D, and then the juice flows out of the buffer tank 818 through the channel 818G defined by the first opening 818D (at the second end 818C) and the second opening 818F of the buffer tank 818 to reach the mixing chamber 806. In the mixing chamber 806, the juice is mixed with the water suctioned by the user. Thus, the mixture between the water and the juice is conveyed to the outlet 816 and then consumed by the user.

[0149] The cap assembly 800 can also be used without using a straw connected to the outlet 816. In this way, when the cap assembly 800 is assembled to the first container, it works like a baby bottle when the cap assembly 800 is used. In other words, when the cap assembly 800 works in this way, Figure 20 and Figure 33 the shown cap assembly 800 is upside down.

[0150] The cap assembly 800 is also provided with an adjustment device for adjusting the concentration of the first liquid to be mixed and the second liquid to be mixed for mixing. The adjustment device can be achieved at least by using the adjustment member 810 that cooperates with the buffer tank 818.

[0151] Regarding the above content, especially with respect to FIGS. 26 to 29, those skilled in the art can understand that the mixing between the water and the juice in the mixing chamber depends on the amount of juice flowing into the mixing chamber when the Venturi effect occurs.

[0152] It can be understood that in the first case, when the position of the opening at the protrusion 812C of the second container 812 is exactly above the first opening 818D (at the first end 818B) of the buffer tank 818, the fluid path (defined by the opening at 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 case, when the Venturi effect occurs, the amount of juice flowing into the mixing chamber 806 is at its maximum. It can also be understood that in the second case, when the position of the opening at the protrusion 812C of the second container 812 is exactly above the second end 818C of the buffer tank 818, the fluid path (defined by the opening at the protrusion 812C of the second container 812 and the channel 818G of the buffer tank 818) is blocked or deactivated. In the second case, when the Venturi effect occurs, the amount of juice flowing into the mixing chamber 806 is the least. In the second case, for some embodiments, when the Venturi effect occurs, the amount of juice flowing into the mixing chamber 806 is zero, depending on the design of the cap assembly 800.

[0153] Specifically, in Figures 29B to 29CTaking the illustration in Figure 29B as an example, the fluid path in Figure 29C is fully established or enabled. Conversely,

[0154] For the above description, it should be understood that by rotating the second container 812 or the adjustment member 810 or both circularly in a clockwise or counterclockwise direction around the outlet 816, the user can selectively adjust the amount of juice flowing into the mixing chamber 806 for mixing therein, depending on the actual design of the lid assembly 800.

[0155] For the above, it should be understood that the liquid dispensing device according to the present invention includes a utility portion in fluid communication with a first liquid contained in a base member (first container); a second container storing a second liquid is in fluid communication with the utility portion. The operation of the liquid dispensing device involves the above.

[0156] Those skilled in the art should understand that the disclosed adjustment or adjustment mechanism is merely an example and should not be construed as a limitation on the gist of the present invention. As long as the user can adjust the amount of juice flowing out of the second container during the Venturi effect for mixing with the first liquid, this falls within the gist of the present invention. Specifically, as long as the user can adjust the fluid communication between the first container and the second container through the adjustment mechanism, especially during the Venturi effect, this falls within the gist of the present invention.

[0157] Figure 34 is a cross-sectional perspective view of the lid assembly 900, which is a variant of the lid assembly 800. Only the differences between the lid assemblies 800 and 900 will be described below.

[0158] FIG. 35 shows the vent 920 in different views, where Figure 35A is a perspective top view, Figure 35B is a perspective bottom view, and Figure 35C is a side view. Optionally, the vent 920 is an umbrella valve having a diaphragm-shaped sealing disk that allows one-way flow while preventing backflow. Such vents are well known in the art and thus the content herein will not be described in detail.

[0159] FIG. 36 shows the lid member 908 in different views, which is a variant of the lid member 808. Figure 36A is a perspective top view, Figure 36B is a perspective bottom view, and Figure 36C is a bottom view. It differs from the lid member 808 in the recess 908F for accommodating the vent 920.

[0160] FIG. 37 shows the mixing chamber 906 in different views, where Figure 37A is a perspective top view, Figure 37BIt is a perspective bottom view. The mixing chamber 906 is provided with a pair of wings 906A for facilitating the removal of the mixing chamber 906 from the lid member 908 for the user.

[0161] Figure 38 shows the adjustment member 910 in different views, which is a variant of the adjustment member 810. Figure 38A It is a perspective top view, Figure 38B It is a perspective bottom view. Referring Figure 34 to Figure 38, it can be seen that after the adjustment member 910 is assembled to the lid member 908, the periphery of the adjustment member 910 is exposed outward. The serpentine periphery 910A of the adjustment member 910 provides convenience for the user to rotate the adjustment member 910 around the nozzle opening.

[0162] Figure 39 shows the second container 912 in different views, which is a variant of the second container member 812. Figure 39A It is a perspective top view, Figure 39B It is a perspective cross-sectional view, and Figure 39C It is a side cross-sectional view. Figure 40 shows the assembly of the vent 920 and the mixing chamber 906 to the lid member 908, where Figure 40A It is a bottom view and Figure 40B It is a perspective bottom view.

[0163] Figure 41 It is an exploded view of the perspective top view of the lid assembly 900. Figure 42 It is an exploded view of the perspective bottom view of the lid assembly 900. Figure 43 It is the assembly of the lid assembly 900 to the base member to form a bottle according to the present invention.

[0164] Figure 44 It is a schematic diagram showing the operation of a beverage dispenser provided with a liquid dispensing device according to the present invention. The beverage dispenser is designed to cater to a wide range of beverage preferences. Specifically, it allows the user the flexibility to choose between consuming an independent first liquid or selecting a mixture of the first liquid and the second liquid according to their individual needs and expectations. In addition, the beverage dispenser enables the user to precisely adjust the concentration of both the first liquid and the second liquid to be mixed together.

[0165] The beverage dispenser in this embodiment includes several basic components, which include a body having a dispenser outlet, a water tank (serving as the first container for the first liquid), a nano filter, an electric pump, and a cartridge storage (serving as the second container for the second liquid), and a liquid dispensing device according to the present invention. As Figure 44As shown, these components are intelligently electrically interconnected and fluidly interconnected to ensure seamless operation. Importantly, the beverage dispenser is equipped with a control panel. Preferably, the cartridge reservoir is disposable or replaceable, thus providing the advantage of preventing bacteria growth in the beverage dispenser. Preferably, the tube connecting the electric pump and the water tank is also replaceable, serving the same advantage of preventing bacteria growth in the beverage dispenser.

[0166] In some embodiments, the dispensing outlet is a specially designed nozzle that allows the discharge of the first liquid and / or the second liquid while achieving the desired mixing. This means that users can conveniently select and enjoy their preferred liquid combinations, whether it is water, energy drinks, or other flavor options available in the dispenser, particularly in the cartridge reservoir. Preferably, the nozzle is disposable or replaceable, thus providing the advantage of preventing bacteria growth in the beverage dispenser.

[0167] The water tank, as the main container, holds the water supply for the dispenser. It ensures a stable source of clean and fresh water. To enhance the quality of the dispensed beverage, a nano filter is integrated into the system. This specialized filter effectively removes impurities and contaminants, thus ensuring a purer and healthier drinking experience. Preferably, the nano filter filters the water before it enters the liquid dispensing device.

[0168] The nano filter, as a key component of the beverage dispenser, is designed to have advanced filtering capabilities to ensure the highest quality of the dispensed beverage. It incorporates nanofibers and / or activated carbon materials, which are preferably arranged in a rod-like configuration. This novel design maximizes the filtering efficiency and effectiveness of the nano filter.

[0169] The main function of the nano filter is to eliminate various contaminants from the water or other liquids used in the dispenser. It is specially designed to meet strict quality standards, such as NSF42 requirements, by effectively removing chlorine, taste, and odor.

[0170] This ensures that the dispensed beverage not only has no unpleasant taste and odor but also meets the desired taste expectations.

[0171] In addition to removing taste and odor, the nano filter also excels in eliminating heavy metals, thus meeting NSF53 requirements. Heavy metals, known for their potential harmful effects, are effectively filtered out, thus safeguarding 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.

[0172] Furthermore, the nano filter demonstrates excellent performance in eliminating bacteria and viruses, achieving a remarkable 99% removal rate. This high level of filtration ensures that the dispensed beverage is safe and free from harmful microorganisms, thus reassuring the users.

[0173] By combining the filtering capabilities of nanofibers and activated carbon materials, the nanofilter provides comprehensive purification of the liquid passing through it. It serves as a reliable barrier, capturing impurities and ensuring that only clean and high-quality water or liquid forms the final beverage. This advanced filtration technology enhances the overall taste, purity, and safety of the dispensed beverage, making it the desired choice for consumers seeking a premium drinking experience.

[0174] The electric pump plays a crucial role in the beverage dispenser, facilitating the smooth flow and delivery of the desired beverage. It effectively transfers the filtered water or other liquid from the water tank or cartridge reservoir to the dispensing outlet, thus ensuring a consistent and controlled dispensing process.

[0175] The beverage dispenser is equipped with a control panel. Referring to the schematic Figure 1 , it should be understood that the control panel can control the electric pump.

[0176] In some embodiments, the control panel can operate all components in the beverage dispenser. The 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.

[0177] The cartridge reservoir, serving as a secondary container, provides a convenient space for storing additional ingredients or flavorings. This allows the user to easily add various cartridges containing flavor concentrates, nutritional supplements, or other liquid enhancers. By combining these cartridges, the beverage dispenser offers a wide range of customizable beverage options to suit individual preferences. Preferably, these cartridges can be disposable or reusable, thus providing flexibility to accommodate different preferences and requirements.

[0178] The liquid dispensing device is designed to include a chamber having three basic components: a first inlet, a second inlet, and an outlet. The operation of the liquid dispensing device is the same as 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 passage. On the other hand, the second inlet is fluidly connected to a cartridge reservoir, which in turn is connected to a cartridge containing a flavor concentrate, a nutritional supplement, or other liquid enhancer. Additionally, 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 passage. The outlet of the liquid dispensing device is directly connected to the dispensing outlet. The operation of the liquid dispensing device is as follows: When the electric pump is activated to pump water from the water tank towards the dispensing outlet, the high velocity of the water within the liquid dispensing device causes a Venturi effect at the second inlet. Consequently, the pressure at the second inlet is reduced. This effect allows the contents within the cartridge to be suctioned out and conveyed from the cartridge towards the liquid dispensing device via the second inlet. Once within the liquid dispensing device, the contents of the cartridge come into contact with the flowing water and begin to mix. This process enables the contents to be fully mixed and integrated with the water. Thus, water and the desired liquid (such as juice) are effectively combined and mixed within the liquid dispensing device. It is important to note that the intensity of the Venturi effect is directly affected by the power or intensity of the electric pump. Preferably, the liquid dispensing device is disposable or replaceable, thus providing the advantage of preventing bacteria growth in the beverage dispenser.

[0179] In certain embodiments, the beverage dispenser is characterized by a configuration in which the liquid dispensing device, the cartridge reservoir, and the nano filter are housed within the body of the dispenser. This placement ensures a compact and streamlined design. The water tank is positioned externally, thus providing convenience for refilling purposes. It is important to note that the arrangement of these components can vary according to specific requirements and design considerations. The actual placement and configuration of the cartridge reservoir, the nano filter, and the water tank are determined based on actual needs, thus allowing flexibility and optimization of the overall design of the beverage dispenser.

[0180] The beverage dispenser is equipped with various features to enhance functionality and control the dispensed liquid. For example, a button is provided. The button serves as an activation and deactivation control, thus allowing the user to start and stop the dispensing process as needed.

[0181] Additionally, the dispenser features a rotating disk that provides precise control over the blended concentrate between the first and second liquids. By adjusting the rotating disk, users can finely tune the ratio or strength of the blend according to their personal preferences. This level of control enables users to create customized beverages with an exact balance of the flavors and concentrations they desire. It is worth emphasizing that the rotating disk plays an important role in influencing the Venturi effect that occurs at the second inlet of the liquid dispensing device. This is achieved by providing control over the volumetric flow rate of the contents from the cartridge to the liquid dispensing device. By adjusting the rotating disk, users can regulate the contents aspirated from the cartridge towards the liquid dispensing device. This in turn affects the intensity of the Venturi effect generated at the second inlet. The ability to control the Venturi effect via the rotating disk provides users with greater flexibility in customizing their beverages.

[0182] The combination of the button and the rotating disk enables users to effortlessly dispense and customize their beverages to suit their taste preferences. Whether it is a refreshing blend of water and flavorings, an energizing blend of energy 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.
