[0049] Figure 1 A drinking bottle, designated by reference numeral 100, is shown as a first embodiment of the present invention. The drinking bottle 100 includes a base member 200, a handle member 300, and a lid assembly 400 placed on top of the base member 200. It is generally understood that the terms "upper and lower," "on and below," "front and back," "top and bottom," "horizontal, vertical," and "high and low" are used herein to indicate relative directions or positions, and their definitions are equivalent to the spatial layout shown in the drawings, i.e., the direction of entry into the drawings. Figure 2 A base member 200 is shown including a cylindrical peripheral wall and a top-opening opening, which is designed with a cylindrical profile to hold water, beverages or other beverages for drinking. Figure 3 A handle member 300 is shown including an opening sized and dimensioned to fit the diameter of the cylindrical peripheral wall of the base member. Figure 1-3 It can be understood that the handle member 300 is assembled to the base member 200 by passing the opening of the handle member 300 through the cylindrical peripheral wall of the base member 200 .
[0050] Figure 4 4 is an exploded view of the cover assembly 400 , which includes a base plate 4100 , a trigger 4200 , a first lever arm 4300 , a second lever arm 4400 , a first seal 4500 , a second seal 4600 , a shaft 4700 , and a biasing member 4800 . Figures 5A-5D The substrate 4100 is shown in different views, wherein Figure 5A It is a three-dimensional top view; Figure 5B It is a stereoscopic bottom view; Figure 5C It is a front view; Figure 5D It is a bottom view. It can be seen that the lower part of the base plate 4100 is provided with a joint 4110 that is adapted to the size of the top opening of the base member 200. It is within the ability of a person skilled in the art to clamp or screw the cover assembly to the base member in a standard manner by push-fit or threading. The top surface of the base plate is provided with a slide groove 4102 with a rectangular outline. Figure 5C In the embodiment, the chute is provided with a first hole 4104, a second hole 4106 adjacent to the first hole 4104, and a stopper 4112. A groove 4114 is provided on the side of the chute 4102. Figure 5B , it can be seen that a pair of connecting members 4108 are provided on the bottom side of the top surface, each of which is provided with a hole. Preferably, the connecting members 4108 are elastic.
[0051] Figures 6A-6E The trigger 4200 is shown in different views, where Figure 6A It is a front view. Figure 6B is the bottom view, Figure 6C It is a side view. Figure 6D It is a three-dimensional top view. Figure 6E It is a three-dimensional bottom view. Figure 6A The trigger 4200 is shown as a slider, for example, and the top side of the trigger is provided with a first hole 4202. The first hole 4202 is a through hole. A collar 4204 and an actuating portion 4210 (see FIG. 42) are provided on the bottom side of the top side of the trigger. Figure 6E ). A gap 4206 is provided on the side of the trigger to divide the side of the trigger into several parts, so as to facilitate the assembly of the trigger into the slide groove 4102 of the base plate 4100. Figure 6CAs shown, it can be seen that the middle portion of the side of the trigger 4200 is provided with a side finger portion 4208. By receiving the side finger portion 4208 into the groove 4114 of the base plate 4100, it is facilitated to install the trigger 4200 into the slide 4102. Preferably, the length of the groove 4114 is longer than the length of the side finger portion. By positioning the side finger portion of the trigger into the groove of the base plate, the trigger 4200 can slide in the slide 4102 between a first position (in which the first hole 4202 of the trigger 4200 is above the first hole 4104 of the base plate 4100) and a second position (in which the second hole 4106 of the base plate 4100 is exposed). Preferably, in the first position, the second hole 4106 is not visible. More preferably, in the second position, the first hole 4104 is not visible. In order to maintain the position of the trigger 4200 in the first position by preventing the trigger 4200 from sliding toward the second position, and vice versa, it is advantageous to provide a stopper 4112 on the base plate 4100 to interfere with the sliding of the trigger 420. Advantageously, as Figure 5C As shown, the stopper 4112 is in the form of a protrusion arranged in the slide groove 4102.
[0052] Figures 7A-7B The first lever arm is shown in different views, wherein Figure 7A is a three-dimensional top view, and Figure 7B As shown, the first lever arm is configured to provide a plate 4302 and a handle 4304 extending downwardly from the periphery of the plate 4302. A pair of connectors 4306 are provided on the periphery of the plate 4302 opposite the handle 4304, such as in the form of a pair of trunnions having holes therein.
[0053] Figures 8A-8C The second lever arm is shown in different views, wherein Figure 8A It is a three-dimensional top view, and Figure 8B is a stereoscopic bottom view, and Figure 8C 4 is a side view. As shown, the second lever arm is configured to provide a plate 4402 and a handle 4410 extending downwardly from the periphery of the plate 4402. A pair of connectors 4408, such as a pair of trunnions having holes therein, are provided on the periphery of the plate 4402 opposite the handle 4410. A seal receiving portion 4404 is provided at the top of the plate 4402, with an engagement member 4406 provided thereon.
[0054] Figure 9 A shaft 4700 having a friction portion 4702 is shown. Figure 10 A biasing member 4800 is shown as an example in the form of a torsion spring. The biasing member has two wings 4802 extending laterally from a central torsion spring 4804, each of which should be considered a biasing member. Although Figure 10Two coil springs 4804 are shown, but those skilled in the art will appreciate that the biasing member 4800 can be formed by one coil spring or more than one coil spring. By default, the biasing member 4800 is configured to have a first state. More specifically, as Figure 10 As shown, each wing 4802 is configured to have a first state. When compressed or under pressure, the biasing member 4800 is configured to have a second state. More specifically, the wings 4802 are configured to have a second state under compression or pressure. It should be understood that the state transition of each wing is independent. It should also be understood that each wing 4802 can be understood as an independent biasing member that can be operated independently. Figure 11 shows the first seal 4500 from different angles. Figure 11A It is a three-dimensional front view. Figure 11B is a cross-sectional view along line XX, Figure 11C is a three-dimensional bottom view, Figure 11D The first seal 4500 has an opening 4502 and is sized and shaped to couple with the first hole 4104 of the substrate 4100, such as by a press fit. Figure 12 A second seal 4600 is shown. The second seal 4600 has an opening 4602 and is sized and shaped to couple with the seal receiving portion 4404 of the second lever arm 4400, such as by a press fit. The assembly between the connector 4108 of the base plate 4100, the first lever arm 4300, the second lever arm 4400, the first seal 4500, the second seal 4600, the shaft 4700, and the biasing member 4800 is shown. Figure 13 Best shown in Figure 13 is a cross-sectional view of the cover assembly 400 including relevant components.
[0055] like Figure 13 As shown, the connector 4408 of the second lever arm 4400 is received in the cavity defined by the connector 4306 of the first lever arm 4300, wherein the biasing member 4800 is disposed between the first lever arm 4300 and the second lever arm 4400 such that the plates of the lever arms 4300 and 4400 are respectively positioned on the wings 4802 of the biasing member 4800. Figure 13As shown, the first lever arm 4300 is located on the right wing 4802, which should be considered to be located on one biasing member; and the second lever arm 4400 is located on the left wing 4802, which should be considered to be located on the other biasing member. A shaft 4700, which has a connecting member 4306 for the first lever arm 4300, a connecting member 4408 for the second lever arm 4400, and a hole through which the torsion spring 4000 passes, is assembled to the base plate 4100, with its ends connected to the connecting member 4108 of the base plate 4100. After being assembled in this manner, each of the first lever arm 4300 and the second lever arm 4400 can rotate about the shaft 4700. It will be appreciated that, through the biasing member 4800, when the first lever arm 4300 is compressed or stressed downward, the lever arm is pivotally displaced downward about the shaft 4700, thereby biasing the respective wing of the biasing member 4800 from its first position to its second position. When the aforementioned compression or pressure is removed, the lever arms return to their original positions due to the resilient force of the respective wings of the biasing member 4800, which has transitioned from the second state to the first state. The operation of the first lever arm 4300 is substantially identical to that of the second lever arm 4400. For the sake of brevity, the details of the operation of the second lever arm 4400 will not be described. It will be appreciated that the resilient connector 4108, handle 4304, and handle 4110 facilitate the user's disassembly of the components of the assembly, for example, to clean or replace worn components.
[0056] Figure 14A -D is to show the flip-flop 4200 from its first position ( Figure 14A ) to its second position ( Figure 14D ) sliding diagram. Specifically, Figure 14A -D shows how the trigger moves from a first position (wherein the first hole 4202 of the trigger 4200 is above the opening 4502 of the first seal 4500) to its second position (wherein the second hole 4106 of the base plate 4100 is exposed). When the trigger 4200 moves, as shown in FIG. Figure 14B As shown in FIG-C, the actuating portion 4210 of the trigger 4200 slides on the engaging member 4406 of the second lever arm 4400, thereby applying a downward force to the second lever arm to rotate it about the axis 4700. As a result, it defines an opening of a first passage between the second hole 4106 and the cavity of the base member 200. When the drinking bottle is inverted (i.e., the base member 200 is oriented upward), the liquid in the base member 200 can flow out of the drinking bottle through the second hole 4106.
[0057] Figure 15 is a perspective cross-sectional view of the cover assembly 400, and Figure 14D corresponds to the status in .
[0058] Figure 16-18 A second embodiment of the lid assembly of the present invention is shown. The first embodiment differs from the second embodiment primarily in the first and second lever arms. The operation of the second embodiment is substantially the same as the first embodiment. The differences between the two embodiments are shown below. Figure 16 The trigger is shown in a first position wherein the first aperture of the trigger is over the opening of the first seal, which corresponds to the Figure 14A The embodiment shown in FIG. Figure 17 A straw 500 in the form of a drinking straw is shown inserted through the first aperture of the trigger and the opening of the first seal and acts on the plate of the first lever arm to apply a downward force to the first lever arm to pivot the first lever arm, wherein the operation of the second lever arm is similar to that of the first lever arm. Figure 14A -D. When the drinking straw 500 is inserted further downward, the user can drink the liquid contained in the base member. Thus, it defines a second passage that allows the user to drink the liquid. It is understood that the user can also insert the drinking straw into the base member. Figure 14A In the embodiment shown.
[0059] Figure 18 The trigger actuating portion is shown positioned on the engaging member of the second lever arm, exerting a downward force on the second lever arm to cause it to pivot. Figure 14A -D, which defines the opening of the first channel between the second hole and the base cavity.
[0060] Figure 19 A third embodiment of the lid assembly of the present invention is shown. The operation of the third embodiment is substantially the same as that of the first and second embodiments. The differences between the third embodiment and the first and second embodiments are shown below.
[0061] FIG20 shows a trigger 5200 in a different view, where Figure 20A It is a first-person perspective stereoscopic bottom view. Figure 20B 6 and 5204. The bottom side of the top side of the trigger 5200 is provided with a collar 5204 (same as the collar 4204 in FIG. 6 ) and a first actuating portion 5210 and a second actuating portion 5220. The first actuating portion 5210 and the second actuating portion 5220 are opposite to the collar 5204 (see FIG. 6 ). Figure 20A -B). It can be seen that the two actuation portions stand from the top and bottom sides of the trigger 5200, and the first actuation portion 5210 is higher than the second actuation portion 5220.
[0062] FIG21 shows a substrate 5100 in different views, wherein Figure 21A is a three-dimensional top view, and Figure 21B The top surface of the substrate is provided with a slide groove 5102 whose outline is set to be rectangular, one end of which is in the form of a slope or ramp deeper than the other end (as shown in FIG. Figure 21A The slide groove 5102 is provided with a first hole 5104, a second hole 5106 adjacent to the first hole 5104, and a stopper 5112. Figure 21A , it can be seen that the second hole 5106 is provided on a slope or ramp. Figure 21B , it can be seen that a pair of legs 5108 are provided on the bottom side of the top surface, and each leg is provided with a finger 5110.
[0063] FIG. 22 shows the connector 600 in different views, wherein Figure 22A It is a three-dimensional top view; Figure 22B It is a stereoscopic bottom view; Figure 22C is a front view. The shape and profile of the connector 600 is configured in the form of a bridge having two legs 602, each leg 602 including a first wall 602a, a second wall 602b, a third wall 602c and a lip 602d. Figure 22B , it can be seen that a hole 604 is provided between the third wall 602c and the lip 602d, and a hole 606 is provided on the third wall 602c. It can be understood that the walls 602a, 602b, 602c and the lip 602d together define a leg cavity for receiving a pair of legs 5108 of the base plate 5100, which will be explained in FIG23, which shows the assembly between the connector 600 and the base plate 5100.
[0064] Figure 23A -C shows a perspective bottom view of the assembly between the substrate 5100 and the connector 600 at different angles. Referring to Figures 21-23, it will be understood that the contour of the leg cavity of the connector 600 is configured to be suitable for receiving a pair of legs 5108. Preferably, the pair of legs 5108 are made of an elastic material. When the legs 5108 are slightly pressed inward, the legs 5108 can pass through the leg cavity of the connector 600, thereby completing the assembly between the connector 600 and the substrate 5100. When the connector 600 reaches the bottom side of the top side of the substrate, the inward force acting on the legs 5108 can be removed, thereby allowing the legs 5108 to relax to their default state, allowing the fingers 5110 of the legs 5108 to be located on the lip 602d of the connector 600 (as shown in Figures 21-23). Figure 23C ), limiting the movement of the connector 600, i.e. preventing the connector 600 from falling when the cap assembly is placed on top of the bottle.
[0065] Figure 24 The assembly between the base plate 5100, the connector 600, the biasing member, the first lever arm, and the second lever arm is shown.
[0066] Figure 25The assembly between the first lever arm 4300, the second lever arm 4400, the shaft 4700 and the connector 600 is shown. For clarity, a cross-sectional view of the first lever arm 4300, the second lever arm 4400 and the connector 600 is shown. It can be seen that the friction portion 4702 of the shaft 4700 is received in the connector 4408. More specifically, the knurling on the friction portion 4702 engages with the inner circumference of the connector 4408. Due to this construction, when the second lever arm 4400 is pressed downward, the second lever arm 4400 and the shaft 4700 rotate synchronously together about the longitudinal axis of the shaft 4700, while the first lever arm 4300 remains stationary. Conversely, when the first lever arm 4300 is pressed downward, the first lever arm 4300 rotates about the shaft 4700, but the shaft 4700 and the second lever arm remain stationary. It will be understood that in Figure 25 The operating mechanism described in Figure 15 It should also be understood that Figure 25 The description in FIG. 4 is merely an example. Those skilled in the art may modify the description and this is also within the scope of the present disclosure. For example, the knurling on the friction portion 4702 may be configured to engage with the inner periphery of the connector 4306 of the first lever arm 4300.
[0067] See also Figures 24-25 , it can be seen that the shaft, the first biasing member, the second biasing member, the first lever arm, and the connecting member can be assembled into a module before being assembled to the base plate, which is convenient for users to assemble.
[0068] Figures 26-28 1 and 2. The diagrams show how the trigger 5200 works in the third embodiment of the cover assembly of the present invention. These diagrams show how the trigger 5200 works from its first position ( Figure 26 ) to its second position ( Figure 28 ) sliding. In particular, Figure 26 and Figure 28 The instructions in correspond to Figure 16 and Figure 18 The following shows the differences between the flip-flop 5200 and the flip-flop 4200. Figure 27 is the transition phase when the trigger moves from its first position to its second position, and vice versa. As shown in the figure, the second actuating portion 5220 of the trigger 5200 slides on the engaging member 4406 of the second lever arm 4400, thereby applying a downward force to the second lever arm to cause it to begin to rotate about its axis. At this time, a small hole is formed between the bottom side of the second sealing member 4600 and the top side of the base plate. Such a small hole allows the pressure that may have built up inside the bottle to be released. When Figure 27 When the trigger 5200 further slides to the second position, the above-mentioned first channel is formed.
[0069] Figures 29A-29D The first seal 5500 is shown at different angles. Figure 29A It is a three-dimensional front view. Figure 29B is a cross-sectional view along line XX, Figure 29C is a stereoscopic bottom view, and Figure 29D is a side view. In particular, Figure 29C A first seal 5500 is shown configured with a first hole 5202, and Figure 29D The first seal 5500 is shown having a skirt 5204 .
[0070] Figures 30A-30B The second lever arm 5400 is shown at different angles, wherein Figure 30A is a three-dimensional front view, and Figure 30B It is a three-dimensional bottom view. It can be seen that the first sealing member 5400 is provided with a joint member 5406.
[0071] Figures 31-33 FIG. 1 is a schematic diagram showing a trigger of the fourth embodiment of the cover assembly sliding from its first position to its second position. Figures 31-33 The operating mechanism described in Figures 26-28 For brevity, Figures 31-33 The operating mechanism described in will not be explained again.
[0072] Figure 34A fourth embodiment of the present invention is shown. For the sake of brevity, only the essential differences from the previous description will be explained below. This embodiment includes a base plate 5100', which can be attached to a container and has two openings: the first opening and the second opening described above. The bottom side of the base plate 5100' is equipped with a pair of connectors 600' as described above. Below the first opening of the base plate 5100' is a first lever system comprising a first lever arm 4300' and a first biasing member 4800-1. The first lever system is pivotally connected to the connector 600' in a biased manner, allowing it to move between two positions. In the first position, the first lever arm 4300' closes the first opening of the base plate 5100' with the first seal, while in the second position, the first lever arm 4300' moves away from the first opening. In other words, the first lever arm is pivotally connected to the pair of connectors via a first axis and the first biasing member, allowing the first lever arm to be reciprocally biased between its first and second positions. Similarly, below the second opening of the base plate 5100' is a second lever system comprising a second lever arm 4400' and a second biasing member 4800-2. This second lever system is also pivotally connected to the connecting member 600' in a biased manner. It can be reciprocally biased between a first position (in which the second lever arm 4400' closes the second opening of the base plate 5100' with the second seal) and a second position (in which the second lever arm 4400' is moved away from the second opening). In other words, it can be seen that the second lever arm is pivotally connected to the pair of connecting members via a second axis and a second biasing member, allowing the second lever arm to be reciprocally biased between its first and second positions. The second lever arm 4400' is designed with an engaging member that can be received in the second opening of the base plate 5100' described in the previous embodiment. Furthermore, the lid assembly in this embodiment includes the same trigger as described in the previous embodiment, and its operation and function are the same as those described in the previous embodiment. Based on the above description, it can be understood that the present invention can use a single axis or two axes to bias the first and second lever arms. Depending on actual needs, biasing can be achieved by a single biasing member or two biasing members. Figure 34 The embodiment in the present invention illustrates the Figure 19 However, it should be understood that these variations or modifications can also be applied to the embodiment of Figure 1For the sake of brevity, a detailed description is not given in this specification. It is straightforward and unambiguous for a person skilled in the art to understand that by providing two pairs of holes in a pair of connectors 4108, two shafts can be accommodated in the holes to achieve biased operation of the first and second lever arms.
