[0046] Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
[0047] As explained above, beverage containers with straw lids can cause issues for users wishing to use them with carbonated fluids. Pressure can build up in the beverage container and then exit through the straw when the user opens the straw. In order to minimize this issue, a pressure retention and release mechanism is provided to depressurize the beverage container before the user opens the straw. By providing an actuation assembly that releases built-up pressure from the beverage container before enabling the user to open the straw, instances of the straw spraying the user with liquid can be reduced.
[0048] Accordingly, as shown in FIGs. 1A-1C, a beverage container system 100 is provided and generally includes a lid assembly 200 and a drinking vessel 700. The lid assembly 200 includes a lid body 210, a lid cover 214, a straw assembly 400, a valve assembly 500, and an actuator assembly 600, as shown in FIG. 2. A handle 316 can also be provided, as shown. In general, the actuator assembly 600 is moveable to open the valve assembly 500, and thereby release pressure from a first opening in the lid assembly 200. Movement of the actuator assembly 600 also unlocks the straw assembly 400, allowing a user to move the straw assembly 400 to the open position, thereby opening a second opening in the lid assembly 200 for allowing a fluid to flow there through. In other embodiments, the straw assembly 400 can be configured to automatically move to the open position.
[0049] The lid body 210 is shown in more detail in FIGs. 3A-3B and generally includes a hollow, generally cylindrical outer wall 217 with an end plate 220 extending across an upper end thereof. The outer wall 217 can be configured to extend over and mate to the drinking vessel 700, discussed in further detail below. In the illustrated embodiment, an inner surface 278 of the outer wall 217 includes threads 282 extending there around for mating with threads 284 formed on an outer surface of the drinking vessel 700, as described below in more detail. The outer wall 217 can vary in diameter, and can include one or more stepped regions 222. The particular configuration can vary based on the configuration of the drinking vessel 700.
[0050] The end plate 220 can have a variety of configurations, but in the illustrated embodiment it is generally planar with a top surface 224 (FIG. 3A) and a bottom surface 226 (FIG. 3B) . The end plate 220 can include features to facilitate mounting of the various assemblies.
[0051] In order to facilitate mounting of the straw assembly 400, the top surface 224 can include first and second support members 228a, 228b that are spaced apart from each other and protrude upward adjacent an outer perimeter of the top surface. Each of the first and second support members 228a, 228b can include first and second cutouts 232a, 232b, respectively, configured to hold respective first and second pins 414a, 414b of the mouthpiece 402, as described below in more detail. As illustrated, each of the cutouts 232a, 232b has a semicircular shape, but the cutouts 232a, 232b can have any shape suitable to hold a mouthpiece 402 of the straw assembly 400.
[0052] The top surface 224 can also include a singular opening 260 positioned generally between first and second support members 228a, 228b for receiving the straw assembly 400. As illustrated, the opening 260 is circular and extends from the top surface 224 through a straw guide 261 of the bottom surface 226 such that a bore is formed through the end plate 220. The straw guide 261 is discussed below in more detail.
[0053] The top surface 224 can also include features configured to support a snap frame 216 (FIG. 2) , which aids in coupling the lid body 210 and the lid cover 214. As shown, the end plate 220 includes first and second support towers 242a, 242b spaced a distance apart from one another and protruding from a central region of the top surface 224. Each support tower 242a, 242b can be generally cylindrical and can include a bore 244a, 244b extending there through. The support towers 242a, 242b can couple with corresponding first and second tubes 331a, 331b on the snap frame 216, shown in FIG. 2, thus allowing the snap frame 216 to function as a mounting bracket that supports the lid cover 214 on the lid body 210.
[0054] The top surface 224 can further include first and second support features 246a, 246b configured to support the valve assembly 500. Each of the first and second support features 246a, 246b can protrude upward from the top surface 224 on each side of a recess 248 that receives the valve assembly there through. In the illustrated embodiment, the first support feature 246a includes a vertical member 250 supported by one or more legs 254, and the second support feature 246b is U-shaped and opens toward the recess 248, however other support techniques can be utilized. The first and second support features 246a, 246b can be configured to support a first and a second pair of wings 518, 520 on a valve body 502, discussed below in more detail. The shape of the recess 248 can vary depending on the shape of the valve body 502 received therein, but in the illustrated embodiment it includes a circular portion 256 and a square portion 258. The entirety of the recess 248 extends from the top surface 224 through a valve guide 259 of the bottom surface 226, as discussed further below.
[0055] The bottom surface 226 of the end plate 220, shown in more detail in FIG. 3B, is likewise generally planar with various features formed thereon. As shown, the illustrated bottom surface 226 includes the straw guide 261 through which the singular opening extends. The straw guide 261 protrudes downward from the bottom surface 226 and is generally cylindrical. The bottom surface 226 further includes the valve guide 259 which likewise extends downward and is generally cylindrical. The valve guide 259 includes a circular portion 264 and a square portion 266 corresponding to the respective circular portion 256 and square portion 258 of the recess. The circular portion 264 of the valve guide 259 protruding from the bottom surface 226 can include a support structure 227 extending across the bottom-most end thereof and defining a central opening 270 and first and second surrounding openings 272a, 272b. This structure can aid in supporting the valve assembly 500, discussed further below.
[0056] As indicated above, the lid body 210 includes a cylindrical outer wall 217 that supports the end plate 220. The cylindrical outer wall 217 can include one or more engagement members 280 positioned there around for coupling to the lid cover 214, discussed in further detail below. As illustrated, each of the engagement members 280 is U-shaped for receiving corresponding notches 332 on the lid cover 214, discussed below. However, the engagement members 280 can be any shape suitable to enable to lid body 210 to couple to the lid cover 214. As illustrated in FIGs. 3A and 12A-12B, the cylindrical outer wall 217 further includes a mounting feature 285 for pivotally supporting a lever 604 on the lid body 210, as discussed below in more detail.
[0057] The lid cover 214 is shown in more detail in FIG. 4A and 4B, and as shown generally includes an outer cylindrical sidewall 290 having an upper surface 286 extending across one end thereof. Such a configuration enables the lid cover 214 to be positioned over and conceal the components of the lid body 210. The lid cover 214 can include features to seat a portion of the straw assembly 400 as well as the actuator assembly 600.
[0058] As shown in FIG. 4A, the lid cover 214 includes a longitudinal opening or channel 296 having a first channel portion 296a extending across the upper surface 286 from an outer edge 288 of the lid cover 214, and a second channel portion 296b extending downward along the sidewall 290. A continuous ridge 304 can optionally border the outer perimeter of the channel 296. An end surface 308 of the first channel portion 296a can include a first retention tab 310 projecting outward therefrom, and an end surface 312 of the second channel portion can include a second retention tab 314 protruding therefrom. The first and second retention tabs 310, 314 are described below in more detail, but generally aid in retaining the straw assembly in the closed and opened positions respectively. A groove 306 can be formed below the second channel portion 302 for slidably seating a slide button 606 of the actuator assembly 600, discussed below in more detail.
[0059] As further shown in FIG. 4B, an inner surface 292 of the lid cover 214 can include first and second attachment members 330a, 330b protruding downward therefrom for engaging with the corresponding first and second tubes 331a, 331b of the snap frame 216. Each of the first and second attachment members 330a, 330b can be generally cylindrical and can include a bore 323 extending there through for receiving the snap frame tubes 331a, 331b therein.
[0060] The inner surface 294 of the sidewall can also include the notches 332, as indicated above, positioned there around and configured to couple to the engagement members 280 on the lid body 210 to retain the lid cover 214 on the body 210.
[0061] As further shown in FIG. 4A, and in FIG. 2, the lid cover 214 further includes a straw holder 218 in the form of a generally elongate, concave recess that is configured to hold the mouthpiece 402 when the mouthpiece 402 is in a closed position. The straw holder 218 can be formed integrally with the lid cover 214, or as shown can be in the form of a separate member mounted within the first channel portion 296a of the lid cover 214.
[0062] The lid cover 214 can also include a handle 316 to facilitate carrying of the device. As shown in FIG. 5, the illustrated handle 316 includes a base 318 and a holding portion 320. The holding portion 320 is in the form of a hoop-shaped strap, however the holding portion 320 can have any shape that enables a user to hold the handle 316. The base 318 can be mounted between first and second projections 322a, 322b on the lid cover 214. Each of the first and second projections 322a, 322b and the base 318 can include a central opening 321 for receiving a pin 328 to retain the base 318 on the lid cover 214 and to allow pivotable movement of the base 318 and thus the handle 316 relative to the lid cover 214. Other mating configurations can also be used.
[0063] Turning to FIGs. 6A-6C, the straw assembly 400 is shown in more detail and generally includes a mouthpiece 402, a flexible straw 404, a straw hood 406, and the straw pipe (not shown) . The mouthpiece 402 can be generally rigid for supporting the flexible straw 404, and can be in the form of an elongate generally tubular body 410. The particular shape of the tubular body 410 can vary, and in one embodiment, as illustrated, the body can have a generally oblong or oval cross-sectional shape. The mouthpiece 402 can further include a lower frame 412 with first and second pins 414a, 414b extending outward therefrom in opposed directions, and first and second arms 416a, 416b extending radially outward from each pin 414a, 414b. The first and second pins 414a, 414b can be configured to rest in the first and second cutouts 232a, 232b in the first and second support members 228a, 228b on the lid body 210, respectively. The first and second pins 414a, 414b are configured to rotate in response to movement of the mouthpiece 402 such that the first and second arms 416a, 416b lie parallel to respective first and second blocking features, (e.g., protrusions 614a, 614b) when the straw assembly 400 is in the closed position, and the first and second arms 416a, 416b lie perpendicular to the respective first and second protrusions 614a and 614b when the straw assembly 400 is in the open position. The operation of the straw assembly 400 in the closed position and the open position is discussed below in more detail.
[0064] With reference to FIG. 6C, as indicated above the mouthpiece 402 is configured to support the flexible straw 404 of the straw assembly 400. The flexible straw 404 can be resilient and can be formed from various flexible materials, including various elastomers such as silicone. The flexible straw 404 can be biased toward the open position. The straw 404 is configured to be housed within the hollow interior of the mouthpiece 402. An opening 432 of the straw 404 is formed just proximal to the opening 428 of the mouthpiece 402 and a length 434 of the straw 404 extends through the body 410 of the mouthpiece 402. A portion of the straw 404 extending through the lid body 210 can include a bend or curved portion 436 to enable the straw hood 406, discussed below, to extend there over. The straw 404 can have a length 434 that extends downward through the opening 260, through the straw guide 261, and through the bottom surface 226 of the end plate 220. A straw pipe, not shown, can slide into the straw 404 and can extend downward into the drinking vessel 700. The pipe, not shown can be of variable length and is configured to enable fluid contained in the drinking vessel 700 to be sucked through the straw 404.
[0065] As indicated above, the straw hood 406 can extend over the curved portion of the rear surface 426 of the flexible straw 404. In one embodiment, the hood 406 can be a separate piece (FIGs. 6B and 6C) that fixedly attaches to the rear surface 426 of the mouthpiece 402 to form an integrated structure (FIG. 6A) . In another embodiment, the hood 406 can be monolithically formed with the mouthpiece 402 to provide the straw assembly 400 with additional rigidity. In each embodiment, the hood 406 can cover the curved portion 436 of the straw 404 when the straw 404 is in the open position. When the mouthpiece 402 pivots from the open position to the closed position, the hood 406 can be configured to pinch the curved portion 436 of the straw 404 and thereby block the flow of fluid from the drinking vessel 700 to the opening 432, as will be described in more detail below.
[0066] FIGs. 7A-7F illustrate the valve assembly 500. The illustrated valve assembly 500 generally includes the valve body 502, a push button 504, and a thrust device 506 having a biasing member such as a spring 508 disposed there around and having a sealing member (e.g., a gasket 510) at a bottom end thereof. These components work together to block and unblock fluid flow through the recess 248 in the lid body 210 of the drinking vessel 700.
[0067] The illustrated valve body 502 is generally cylindrical and includes a head 512 and first and second legs 514a, 514b formed by opposed cut-outs in the cylindrical body 502. The valve body 502 can also include first and second pairs of wings 518, 520 extending radially outward from opposed sides of the body 502. As illustrated, the first pair of wings 518 extends adjacent the first leg 514a and the second pair of wings 520 extends adjacent the second leg 514b. The valve body 502 can be positioned in the recess 248 in the lid body 210, discussed above, such that the first pair of wings 518 is coupled to the vertical member 250 of the first support feature 246a and the second pair of wings 520 is secured inside the second support feature 246b. The valve body 502 can further include a bore 522 extending longitudinally there through, as illustrated in FIG. 7E. As shown in FIG. 7A, the valve body 502 is positioned on top of the push button 504 such that the push button 504 extends through the bore 522 to couple the valve body 502 to the push button 504. Returning to FIG. 7E, the inner circumference of the head 512 includes projections 524 spaced apart from each other such that recesses 526 are formed between the spaced projections 524. When the push button 504 is pressed down to open the valve assembly 500, the thrust device 506 is also pushed down and rotates clockwise, as illustrated in FIG. 7F. Subsequently, when the spring 508 urges the thrust device 506 back up, the projections 524 block corresponding protrusions 530 (FIG. 7D) on the push button 504 to prevent the push button 504 from moving back up, thereby retaining the valve in the open position. When the push button 504 is pressed down a second time, the thrust device 506 rotates again, but this time when the spring 508 urges the thrust device 506 back up, the protrusions 530 slide into the recesses 526 rather than being blocked by the projections 524, thereby allowing the valve to return to the closed position. As illustrated in FIG. 7E, the inner circumference includes six projections 524 and six recesses 526. However, the inner circumference can have any number of alternating projections and recesses that allow the valve assembly to operate as described above.
[0068] As discussed above, actuation of the push button 504 supplies the force necessary to rotate the thrust device 506. As illustrated in FIG. 7D, the push button 504 includes a base 532 and a shaft 534 that extends upward from a center of the base. The base 532 is generally cylindrical and includes the protrusions 530 that interact with the projections 524 to rotate the thrust device 506. As illustrated, a bottom surface of each protrusion 530 include angled sidewalls 531 that come together to terminate at a point 536 facing downward. The angled sidewall functions as a cam surface to cause rotation of the thrust device 506.
[0069] Turning to FIG. 7C, the thrust device 506 includes a generally cylindrical head 538 having three longitudinally extending projections 542 spaced radially therearound, and a shaft 544 extending downward therefrom with a stopper 546 at the end. As discussed above, the thrust device 506 rotates upon actuation of the push button 504 to open and close the valve assembly 500. The projections 542 include an angled surface 550 at the top end thereof against which the protrusions 530 move to cause the thrust device 506 to rotate. In particular, downward movement of the push button 504, in response to actuation of the actuator as discussed below, causes the angled sidewall 531 on the protrusions 530 on the push button 504 to contact the angled surface 550 of the thrust device 506, thereby forcing the thrust device 506 to rotate by a certain amount. The amount of rotation is equivalent to the spacing between the protrusions 530 on the push button 504 and the projections 524 on the valve body 502, thereby moving the protrusions 530 and the projections 524 between aligned and misaligned positions. The spring 508 is coiled around the shaft 544 of the thrust device 506, as shown in FIG. 7B, and alternates between being compressed in the open position and expanded in the closed position.
[0070] The sealing member 510 is positioned at the bottom of shaft 544 and functions to block a fluid flow in the closed position. In particular, the sealing member 510 is positioned underneath the valve guide 259 to be flush with the central opening 270 and the first and second surrounding openings 272a, 272b in the lid body 210 in the closed position. Alternatively, when the thrust device 506 is pressed down, the sealing member 510 comes out of contact with the central opening 270 and first and second surrounding openings 272a, 272b and exposes the central opening 270 and first and second surrounding openings 272a, 272b to fluid contained within the drinking vessel 700. This allows any carbonation in the fluid to flow through the lid body 210 rather than the straw assembly 400. The sealing member 510 illustrated in FIGs. 7A-7B is made of silicone.
[0071] As illustrated in FIGs. 8A-8C, the lid assembly 200 further includes an actuator assembly 600. The actuator assembly 600 is configured to actuate the valve assembly 500 to release pressure, while also releasing the straw assembly to enable a user to move the straw assembly to the open position. As shown, the actuator assembly 600 generally includes an actuator 602 and the lever 604. The actuator 602 and the lever 604 can be coupled to each other, or integrally formed as a single unit, such that when a user pushes down the slide button 606 of the actuator 602, the lever 604 pivots and moves downward. The illustrated actuator 602 includes an arc-shaped frame 608 having the slide button 606 positioned thereon. As illustrated, the slide button 606 can be shaped to seat a user’s thumb and can be configured to be positioned within and to slide vertically along the groove 306 in the lid cover 214.
[0072] The frame 608 can also include the first and second protrusions 614a, 614b which block first and second arms 416a, 416b when the straw assembly 400 is in the closed position. The protrusions 614a, 614b in the illustrated embodiment are in the form of upward extending arms. When the straw assembly 400 is in the closed position, the protrusions 614a, 614b are positioned in a blocking position adjacent to the arms 416a, 416b such that the first and second pins 414a, 414b are prevented from rotating. Alternatively, in the open position, the protrusions 614a, 614b are in an unblocked position spaced apart from and positioned below the arms 416a, 416b, allowing the pins 414a, 414b to freely rotate.
[0073] The lever 604 is configured to contact the push button 504 to initiate opening or closing of the valve assembly 500. The illustrated lever 604 is generally u-shaped with two arms 628 extending from a common attachment piece 636, and with hands 622 at the end of each arm 628 which couple the lever 604 to the actuator 602 to allow the lever 604 to pivot in response to sliding movement of the actuator 602. The common attachment piece 636 includes an arm 631 extending there from and having a bar 633 which pivotally mounts to the mounting feature 285 on the lid body 210 to pivotally couple the lever 604 to the lid body 210. As discussed above, the lever 604 pivots about the mounting feature 285 when the actuator 602 moves up and down.
[0074] In operation, as shown in FIGs. 1C and 9, when the straw assembly 400 is in the closed position (FIG. 9) , the mouthpiece 402 is retained in the straw holder 218 by the first retention tab 310, and when the straw assembly 400 is in the open position (FIGs. 1C and 10A) , the mouthpiece 402 is retained in the open position by the second retention tab 314. In particular, the first retention tab 310 engages the opening 428 of the mouthpiece 402, and the second retention tab 314 engages a bottom edge 429 of the mouthpiece 402. Further, the curved portion 436 of the straw 404 is pinched by the hood 406. This allows the straw 404 to provide a pressure seal capable of preventing leakage through the straw 404. Further in this closed position, the first and second arms 416a, 416b of the mouthpiece 402 lie parallel and adjacent to the first and second protrusions 614a, 614b on the lever 604 to prevent the resilient, flexible straw 404 from springing upward into the open position. Also in the closed position, the sealing member 510 is flush with the central opening 270 and first and second surrounding openings 272a, 272b, as illustrated in FIG. 10B.
[0075] The transition from the closed position to the open position begins when, upon actuation by a user, the slide button 606 translates downward within the groove 306 which causes the lever 604 to pivot downward. Downward movement of the lever 604 forces the push button 504 downward. This causes the valve assembly 500 to operate as described above, with the projections 542 on the thrust device 506 moving to a misaligned position with the recesses 526 in the valve body 502 and to an aligned position with the projections 524 in the valve body 502. When the slide button 606 is released, the spring 508 will force the thrust device 506 upward, however the projections 524 in the valve body 502 will interact with the projections 542 on the thrust device 506 thus blocking upward movement of the thrust device 506. At this point, the sealing member 510 is positioned downward from the central opening 270 and first and second surrounding openings 272a, 272b, so any carbonation contained within drinking vessel 700 escapes to underneath the lid cover 214.
[0076] Further, as illustrated in FIGs. 11A-11B, during the initial downward movement of the slide button 606, the protrusions 614a, 614b on the frame 608 translate downward to move to the unblocked position, spaced apart from the arms 416a, 416b on the mouthpiece 402. In one embodiment, the protrusions 614a, 614b can be configured so that they do move away from the arms 416a, 416b until after the valve assembly 500 has opened. Once the protrusions 614a, 614b complete their downward translation and the arms 416a, 416b are free to pivot, a user can manually move the straw assembly 400 to the open position, thereby moving the hood 406 and releasing the straw 404 from the grip of the hood 406.
[0077] To move from the open position to the closed position, a user can manually move the mouthpiece 402. This manual movement allows the lever 604 to pivot upward which forces the push button 504 back up. The valve assembly 500 then operates as described above, but this time with the projections 542 on the thrust device 506 moving into an aligned position with the recesses 526 in the valve body 502 and to a misaligned position with the projections 524 in the valve body 502. From there, the spring 508 will force the thrust device 506 upward, and the projections 542 on the thrust device 506 will pass between the projections 524 in the valve body 502 allowing the valve assembly 500 to return to the fully closed position at the same time the straw 404 seals shut. At this point, the sealing member 510 has moved upward to block the central opening 270 and first and second surrounding openings 272a, 272b, and the frame 608 and slide button 606 have translated upward in response to the spring force, moving the protrusions 614a, 614b back to the blocked position. In this closed position, the protrusions 614a, 614b will block the arms 416a, 416b from rotating.
[0078] As indicated above, the lid assembly 200 can be configured to couple to a drinking vessel configured to retain a fluid. While the drinking vessel can have any configuration, FIGs. 12A-12B illustrate one embodiment of a drinking vessel 700 that is generally cylindrical and includes outer and inner housings 702, 704. An air gap or space 708 can be formed between the outer housing 702 and the inner housing 704 to provide insulation for the inner housing 704 to retain fluid at a desired temperature. An upper end of the housing 702 can have a neck region 283 with threads 284 formed thereon for mating with the threads 282 on the lid assembly 200. A person skilled in the art will appreciate that other mating features can be used, such as a snap fit, a press fit, magnets, etc.
[0079] In some embodiments, the lid assembly described above can feature a variety of configurations. FIGs. 13-15, and the accompanying descriptions provided below, describe exemplary configurations of a lid assembly for use in releasing pressure from a drinking vessel. One or more of components described above with respect to lid assembly 200 may be used in or in conjunction with any one of the lid assemblies described below, and one or more of the components described with respect to any one of the lid assemblies described below may be used in or in conjunction with lid assembly 200.
[0080] FIG. 13 illustrates a cross-sectional view of an additional exemplary lid assembly 1300 that is configured to couple to a drinking vessel (such as drinking vessel 700) . Similar to lid assembly 200, the lid assembly 1300 includes a lid body 1310, a lid cover 1312, a straw assembly 1314 (including a silicone straw 1314a and a mouthpiece 1314b) , a valve assembly 1316, and an actuator assembly 1318. A handle 1320 can also be provided, as shown.
[0081] In general, the actuator assembly 1318 is moveable to open the valve assembly 1316, and thereby release pressure from a first opening 1322 in the lid assembly 1300. For example, as shown in FIG. 13, the actuator assembly 1318 can include a button 1318a which can be pressed in a radially inward direction, to cause a slider switch 1318b to contact a plunger 1316a of the valve assembly to thereby open the valve assembly 1316 and release pressure from within the drinking vessel. Pressing of the button 1318a also causes the slider 1318b to contact a latch 1318c and thereby pivot the engagement feature 1318d of the latch 1318c away from the mouthpiece 1314b. The resilience of the silicone straw 1314a causes the straw assembly 1314 to pivot in the direction of arrow R to the open position, thereby opening a second opening 1324 in the lid assembly 1300 for allowing a fluid to flow there through.
[0082] FIG. 14 illustrates a cross-sectional view of an additional exemplary lid assembly 1400 that is configured to couple to a drinking vessel 1401 (similar to drinking vessel 700) . The lid assembly 1400 includes a lid body 1410, a lid cover 1412, and a straw assembly 1414. A handle 1420 can also be provided, as shown.
[0083] The lid assembly 1400 can also include a pressure relief valve (not shown) located in a first opening (also not shown) in the lid body 1410 configured to permit the release of pressure from the drinking vessel 1401. The pressure relief valve can be actuated via a button (also not shown) which can be pressured by a user. Once the button has been pressed, the user can then manually rotate the straw assembly 1414 into the open position, which causes a drinking valve 1422 disposed in a second opening 1424 in the lid body 1410 to open and thereby allow a fluid to flow there through.
[0084] FIG. 15 illustrates a cross-sectional view of an additional exemplary lid assembly 1500 that is configured to couple to a drinking vessel 1501 (such as drinking vessel 700) . As shown in FIG. 15, the lid assembly 1500 includes some or all of the components of lid assembly 200 described above, including a lid body 1510, a lid cover 1512, a straw assembly 1514 (including a flexible straw 1514a) , an actuator assembly 1516, and a handle 1518. The lid assembly 1500 also includes a valve assembly that features the same design and operation as the valve assembly 500 described above, except that the sealing member 510 is formed as a hard cap 1520 on the side of the valve assembly facing the drinking vessel that can be removed for cleaning. An o-ring (not shown) is disposed between the hard cap 1520 and the main valve body. In addition, the hard cap 1520 is attached to the lid body 1510 or another part of the lid assembly via a cap tether 1522.
[0085] In addition, the lid assembly 1500 includes a pressure relief valve 1524 disposed in an opening of the lid body 1510 which is set to activate at a pressure that is lower than a crimping hold pressure of the flexible straw 1514a when the straw assembly 1514 is in the closed position. In this configuration, the pressure relief valve 1524 acts as a failsafe for the flexible straw when crimped.
