Description

Technical Field

[0001] This utility model relates to the field of drinking bottle technology, and in particular to a drinking bottle with a straw. Background Technology

[0002] Drinking bottles with straws are widely used in daily drinking and exercise due to their convenience and hygiene. To keep the straw opening clean and prevent leakage, most products have a flip-top lid. Early solutions typically used flexible, soft materials for the straw, utilizing the pressure when the lid is closed to bend and seal the straw, with the material's elasticity returning when the lid is opened. However, the soft straw is prone to plastic fatigue under repeated bending over a long period, leading to weakened elasticity, poor rebound, or even failure, resulting in unsatisfactory reliability and lifespan.

[0003] To address the aforementioned issues, existing technology proposes a cup with a telescopic straw, where the straw consists of a fixed extension section and a movable telescopic section, with a spring positioned between the telescopic section and the lid. When the lid is opened, the spring directly pushes the telescopic section upward; when the lid is closed, it directly presses down on the telescopic section, causing it to descend. While this mechanical structure improves reliability to some extent, its control mechanism is simplistic, forcibly synchronizing the straw's lifting and lowering with the lid's opening and closing (opening means popping up, closing means pressing down). This not only fails to achieve on-demand triggering or multi-functional expansion but also limits the optimization of the user experience. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a drinking bottle with a straw that has a simple structure and can realize multiple drinking modes.

[0005] The technical solution adopted by this utility model to solve its technical problem is to provide a drinking bottle with a straw, comprising:

[0006] Bottle body;

[0007] The bottle cap includes a main cap and a flip cap. The main cap is detachably mounted on the bottle body and has a straw that can be vertically inserted into the bottle body, as well as a trigger component for controlling the vertical movement of the straw. The flip cap is rotatably mounted on the main cap and has a closed position and a fully open position.

[0008] When the flip cover rotates from the closed position to the fully open position to a first angle, its outer wall abuts against the trigger component and drives the straw to rise, thereby activating the straw drinking mode; when the flip cover is in the closed position, its inner wall abuts against the top of the straw and causes the straw to descend to the storage state.

[0009] In the above-mentioned drinking bottle with a straw, the main cap is also provided with a direct drinking spout that communicates with the inside of the bottle body; when the flip cap is in the closed position, its inner wall simultaneously abuts against and seals the direct drinking spout and the top of the straw; when the flip cap rotates from the closed position to a second angle, the direct drinking spout is opened while the straw is still in the retracted state, and the second angle is smaller than the first angle.

[0010] In the aforementioned drinking bottle with a straw, the outer wall of the straw is provided with a first locking structure, and the triggering component includes a triggering structure and a second locking structure. The triggering structure extends outside the main cap, and the second locking structure is configured such that: when the flip cap is in the closed position, the second locking structure abuts against the first locking structure and can restrict the straw from rising; when the flip cap abuts against the triggering structure, the second locking structure separates from the first locking structure and allows the straw to rise.

[0011] In the above-mentioned drinking bottle with a straw, the main cap includes a first inner cap and a first outer cap that are connected to each other. The first inner cap is provided with a first guide channel that runs through it in a vertical direction. The straw is vertically inserted into the first guide channel and is fitted with a first elastic element. When the second snap-fit ​​structure is separated from the first snap-fit ​​structure, the first elastic element can drive the straw to rise upward along the first guide channel.

[0012] In the above-mentioned drinking bottle with a straw, the triggering component includes a body and a second elastic member. The triggering structure and the second snap-fit ​​structure are respectively disposed on opposite sides of the body. The second elastic member is disposed between the body and the outer wall of the first guide channel, and the first outer cover is provided with a first opening for the triggering structure to extend out.

[0013] In the above-mentioned drinking bottle with a straw, the first inner cap is provided with two second guide channels that communicate with the first guide channel. The second guide channels are arranged along the tangential direction of the first guide channel, and the body has two sliding arms that are movably engaged in the second guide channels. The second engaging structure is provided with two, and is located at one end of the two sliding arms near the first guide channel.

[0014] In the above-mentioned drinking bottle with a straw, the first outer cap is provided with a second opening and a third opening that penetrates through itself in a vertical direction. The second opening is aligned with and connected to the first guide channel, and the inner diameter of the second opening is adapted to the outer diameter of the straw. The third opening is aligned with the drinking spout, and the inner diameter of the third opening is adapted to the outer diameter of the drinking spout.

[0015] In the aforementioned drinking bottle with a straw, the flip-top includes a second inner cap and a second outer cap. One side of the second inner cap is hinged to the first outer cap, and the other side is engaged with the first outer cap. The second outer cap is horizontally movably disposed on the second inner cap and has a first movable position and a second movable position. When the second outer cap moves to the first movable position, the second inner cap is allowed to rotate around the hinge point. When the second outer cap moves to the second movable position, the rotation of the second inner cap is restricted.

[0016] In the aforementioned drinking bottle with a straw, the first outer cap has a first locking part, the second outer cap has a second locking part corresponding to the first locking part and forming a snap-fit ​​engagement, and the second inner cap also has a horizontally arranged guide part. The second outer cap has a sliding part that is slidably connected to the guide part, and the guide part can restrict the sliding part from moving in the vertical direction. When the second outer cap moves along the guide part to the first moving position, the first locking part and the second locking part separate. When the second outer cap moves along the guide part to the second moving position, the first locking part and the second locking part remain snap-fitted.

[0017] In the aforementioned drinking bottle with a straw, the second inner cap is provided with a mounting groove arranged along the moving direction of the second outer cap, the mounting groove is provided with a third elastic member, and the second outer cap is provided with a driving part that engages with the mounting groove and abuts against the end of the third elastic member; when the second outer cap is subjected to an external force and moves along the guide part toward the first moving position, the driving part can squeeze the third elastic member; when the external force applied to the second outer cap disappears, the third elastic member can drive the driving part to move the second outer cap along the guide part toward the second moving position.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. In this utility model, the bottle cap includes a main cap and a flip cap. The main cap is equipped with a straw that can be vertically inserted into the bottle body, and a trigger component for controlling the lifting and lowering of the straw. The flip cap is rotatably mounted on the main cap and has a closed position and an open position. When the flip cap rotates from the closed position to the fully open position to a first angle, its outer wall abuts against the trigger component and drives the straw to rise, thereby activating the straw drinking mode. When the flip cap is in the closed position, its inner wall abuts against the top of the straw and lowers the straw to a stored state. This design overcomes the shortcomings of traditional soft tubes being prone to fatigue and damage, and the single action of mechanically linked straws. It ensures that the straw is only triggered to rise when the flip cap rotates to a specific first angle, supporting an intermediate state of "open cap without straw rise." This provides users with a flexible choice of step-by-step operation and multiple drinking modes, significantly enhancing the functionality and ease of use of the product.

[0020] 2. In this invention, the main cap also has a drinking spout that communicates with the inside of the bottle. When the cap is in the closed position, its inner wall simultaneously abuts against and seals the drinking spout and the top of the straw. When the cap rotates from the closed position to a second angle, the drinking spout is opened while the straw remains in its retracted state, and the second angle is smaller than the first angle. This design enables independent switching between direct drinking mode and straw mode, allowing users to choose the drinking method according to their actual needs. It satisfies the need for quick hydration through direct drinking while retaining the convenience of straw drinking, effectively expanding the product's applicable scenarios and significantly improving the user experience.

[0021] 3. In this utility model, the outer wall of the straw is provided with a first locking structure, and the triggering component includes a triggering structure and a second locking structure. The triggering structure extends outside the main cover, and the second locking structure is configured such that: when the flip cover is in the closed position, it abuts against the first locking structure and restricts the straw from rising; when the flip cover abuts against the triggering structure, it separates from the first locking structure and allows the straw to rise. This design, through the mechanical interlocking and separation of the locking structure, transforms the lateral drive of the flip cover on the triggering structure into vertical control of the straw's lifting and lowering, effectively preventing the straw from accidentally popping up or failing to move, and ensuring the consistency of the product's movement and structural durability under long-term use.

[0036] like Figures 1 to 7 As shown, in this embodiment, a drinking bottle with a straw includes:

[0037] Bottle body 100.

[0038] The bottle cap includes a main cap 200 and a flip cap 300. The main cap 200 is detachably mounted on the bottle body 100 and has a straw 400 that can be vertically inserted into the bottle body 100, as well as a trigger assembly 500 for controlling the vertical movement of the straw 400. The flip cap 300 is rotatably mounted on the main cap 200 and has a closed position and a fully open position.

[0039] When the flip cover 300 rotates from the closed position to the fully open position to the first angle, its outer wall abuts against the trigger component 500 and drives the straw 400 to rise, thus activating the straw 400 drinking mode. When the flip cover 300 is in the closed position, its inner wall abuts against the top of the straw 400 and lowers the straw 400 to the storage state. This design overcomes the shortcomings of traditional soft tubes being prone to fatigue and damage, and the single action of mechanically linked straws 400. It ensures that the straw 400 is only triggered to rise when the flip cover 300 rotates to a specific first angle, supporting an intermediate state of "open cover without straw rising." This provides users with flexible options for step-by-step operation and multiple drinking modes, significantly enhancing the product's functionality and ease of use.

[0040] Specifically, such as Figures 1 to 7 As shown, in this embodiment, the drinking bottle mainly consists of a bottle body 100, a bottle cap, and a straw 400 inserted into the bottle cap.

[0041] In this embodiment, the bottle body 100 has a hollow structure with an opening at the top for holding liquids such as water, milk, or juice. The opening of the bottle body 100 has internal threads for a detachable connection with the bottle cap, facilitating liquid pouring and cleaning. Preferably, the bottom of the bottle body 100 has an anti-slip pad 600 to improve its stability when placed.

[0042] Furthermore, the bottle cap is used to seal the opening of the bottle body 100 and provides two different drinking modes. Specifically, the bottle cap adopts a split design, including a main cap 200 and a flip cap 300. The main cap 200 is fixed to the top of the bottle body 100 by engaging with the internal thread at the opening of the bottle body 100 through external threads on its outer wall, forming the main sealing structure of the drinking bottle. The flip cap 300 is connected to one side of the main cap 200 via a pivot, allowing for multi-angle opening and closing, so that the user can choose to drink using a straw 400 or a direct drinking spout 211 as needed.

[0043] In this embodiment, the main cover 200 includes a first inner cover 210 and a first outer cover 220 that are interconnected. The two are connected by snap-fit ​​to facilitate disassembly, cleaning, and maintenance. The upper end of the first inner cover 210 is engaged within the receiving groove 226 of the first outer cover 220, and the lower end extends toward the bottle body 100 and is threadedly connected to the bottle body 100, thereby achieving a stable fixation and sealing fit between the main cover 200 and the bottle body 100.

[0044] Furthermore, the first inner cover 210 is provided with a guide channel running vertically through it, for accommodating the straw 400 and providing precise guidance for the lifting and lowering movement of the straw 400. Preferably, the first guide channel 212 is cylindrical, and its inner diameter is larger than that of the straw 400 and the second opening 222, ensuring that the straw 400 will not deviate or get stuck during the lifting and lowering process, thereby ensuring the stability and reliability of the movement of the straw 400.

[0045] Furthermore, the first inner cover 210 is also provided with two second guide channels 213 communicating with the first guide channel 212. The second guide channels 213 are arranged along the tangential direction of the first guide channel 212 and are used to accommodate the two sliding arms 513 of the trigger assembly 500. This design allows the trigger assembly 500 to move smoothly along the second guide channels 213 when subjected to force, thereby achieving reliable contact or separation between the second locking structure 512 and the first locking structure 410 on the straw 400, improving the smoothness of locking and releasing the straw 400. In addition, the tangentially arranged second guide channels 213 also serve as radial limiters, preventing the trigger assembly 500 from rotating or swaying during movement, ensuring the consistency of action, and facilitating the efficient conversion of the lateral thrust applied by the flip cover 300 into the lateral translational movement of the trigger assembly 500.

[0046] Furthermore, the first inner cap 210 is also provided with a direct drinking spout 211 that communicates with the interior of the bottle body 100. This direct drinking spout 211 extends upwards from the surface of the first inner cap 210, and its extended height is greater than the height of the straw 400 in its retracted state. This ensures that the user will not accidentally touch the straw 400 when using the direct drinking spout 211, and the direct drinking spout 211 is preferentially exposed for use when the flip cap 300 is partially opened. The direct drinking spout 211 is integrally formed with the main cap 200, resulting in high structural strength and reliable sealing. This design allows users to choose different drinking methods according to their actual needs, satisfying both the need for quick hydration through direct drinking and the convenience of drinking through the straw 400.

[0047] Furthermore, a second sealing element 710 is fitted onto the end of the first inner cap 210 that connects to the bottle body 100. This second sealing element 710 is located on the axial end face or radial mating surface of the threaded connection between the main cap 200 and the bottle body 100. Its dimensions are adapted to the inner diameter of the bottle body 100 opening, enabling it to undergo uniform compression deformation when the main cap 200 is tightened, thus forming a reliable static seal. Preferably, the second sealing element 710 is a rubber sealing ring.

[0048] In this embodiment, the first outer cover 220 is fitted above the first inner cover 210 and has a recessed receiving groove 226 from bottom to top, which is used to receive the upper end of the first inner cover 210 and cooperate with the first inner cover 210 to form a space for the trigger component 500 to move. This space can protect the internal mechanical structure and extend its service life.

[0049] Furthermore, the first outer cover 220 is provided with a second opening 222 and a third opening 224 that extend vertically through it. The second opening 222 is aligned with and communicates with the first guide channel 212, and its inner diameter matches the outer diameter of the straw 400, allowing the straw 400 to pass through. The third opening 224 is aligned with the drinking spout 211, and its inner diameter matches the outer diameter of the drinking spout 211, allowing the drinking spout 211 to pass through. The two openings are independently provided, achieving physical isolation between the straw 400 channel and the drinking channel, avoiding functional interference, and ensuring independent and reliable operation of each drinking mode.

[0050] Preferably, the inner diameter of the second opening 222 is slightly larger than the outer diameter of the straw 400 and smaller than the inner diameter of the first guide channel 212, so as to allow the straw 400 to move up and down smoothly. The inner diameter of the third opening 224 is slightly larger than the inner diameter of the drinking spout 211, ensuring that the drinking spout 211 can pass through the first outer cover 220 without interference.

[0051] Furthermore, the first outer cover 220 is also provided with an integrally formed first hinge portion, which protrudes outward in a horizontal direction from the side wall of the first outer cover 220, and has a pivot for forming a rotatable connection with the second inner cover 310 of the flip cover 300. Preferably, a torsion spring is sleeved on the pivot for providing a preload force for the flip cover 300 to automatically reset or maintain a closed state, enhancing the opening and closing feel, and ensuring that the flip cover 300 can tightly fit the main cover 200 after closing, thereby improving the sealing performance.

[0052] Furthermore, the first outer cover 220 also has a first opening 221 on its side wall for the trigger structure 511 to extend out. The first opening 221 is rectangular, located below the first hinge, and extends horizontally through one side wall of the first outer cover 220. The size of the opening is adapted to the width and thickness of the trigger structure 511, allowing the trigger structure 511 to slide freely within its range while preventing a large amount of dust from entering the interior.

[0053] Furthermore, the first outer cover 220 is provided with an integrally formed first locking part 225, which is barbed and extends vertically upward from the upper surface of the first outer cover 220 to form a snap-fit ​​with the second locking part 321 on the second inner cover 310 to lock the flip cover 300.

[0054] Preferably, there are two first locking parts 225, located on both sides of the third opening 224, and corresponding one-to-one with the two second locking parts 321. This symmetrical arrangement structure ensures that the flip cover 300 is subjected to uniform force when closed, effectively preventing warping or loosening caused by stress concentration on one side, and significantly improving the stability and reliability of the flip cover 300 when locked.

[0055] In this embodiment, the straw 400 is vertically and flexibly inserted into the first guide channel 212, and the outer wall of the straw 400 is provided with a first locking structure 410. The first locking structure 410 and the second locking structure 512 of the trigger component 500 form a movable abutment engagement, thereby realizing the controlled lifting and lowering of the straw 400. Through this mechanical locking engagement, the straw 400 remains in a stable stored state when not triggered, and is only released by the trigger component 500 when the flip cover 300 is rotated to a specific angle, realizing on-demand activation and effectively preventing malfunction or accidental pop-out.

[0056] Furthermore, the first snap-fit ​​structure 410 includes a snap-fit ​​collar sleeved on the straw 400. The snap-fit ​​collar has two protrusions extending radially along the straw 400, with the two protrusions located on opposite sides of the snap-fit ​​collar in a symmetrical arrangement. These protrusions correspond one-to-one with two second snap-fit ​​structures 512 on the trigger assembly 500. This symmetrical structural design ensures balanced force distribution on the straw 400 during lifting and lowering, preventing jamming or tilting due to uneven loading, and significantly improving motion stability and structural durability.

[0057] Furthermore, a first elastic element 420 is fitted onto the straw 400. Preferably, the first elastic element 420 is a spring. One end of the first elastic element 420 abuts against the bottom wall of the first guide channel 212, and the other end abuts against the lower surface of the snap-fit ​​collar.

[0058] When the second snap-fit ​​structure 512 abuts against the protrusion of the first snap-fit ​​structure 410, the closing pressure of the flip cover 300 is transmitted to the second snap-fit ​​structure 512 through the trigger component 500, which in turn presses down the snap-fit ​​collar, compresses the first elastic element 420, and stores its elastic potential energy. When the flip cover 300 rotates to the first angle, the trigger component 500 moves laterally, causing the second snap-fit ​​structure 512 to separate from the protrusion of the first snap-fit ​​structure 410. At this time, the first elastic element 420 releases its stored elastic potential energy, restores its elastic deformation, and drives the straw 400 to rise along the first guide channel 212, thereby realizing the automatic lifting and reliable positioning of the straw 400.

[0059] Furthermore, a first sealing element 700 is also fitted onto the straw 400. This first sealing element 700 is located between the straw 400 and the first guide channel 212, and its outer diameter matches the inner diameter of the first guide channel 212. It can tightly fit the inner wall of the channel, effectively preventing liquid from leaking around the straw 400 or external air from entering the bottle. Preferably, the first sealing element 700 is a rubber sealing ring.

[0060] In this embodiment, the main cover 200 further includes a trigger assembly 500 disposed between the first inner cover 210 and the first outer cover 220. The trigger assembly 500 includes a trigger structure 511 and a second latching structure 512. The trigger structure 511 extends outside the main cover 200 and is used to contact the outer wall of the flip cover 300 and receive the pushing force applied when it rotates. The second latching structure 512 is configured such that: when the flip cover 300 is in the closed position, the second latching structure 512 abuts against the first latching structure 410 of the straw 400 and can limit the straw 400 from rising under the action of the first elastic member 420, achieving reliable locking; when the flip cover 300 abuts against the trigger structure 511, the second latching structure 512 separates from the first latching structure 410 and allows the straw 400 to rise, enabling the straw 400 to be activated as needed for drinking mode.

[0061] Furthermore, the trigger assembly 500 includes a body 510 and a second elastic member 520. The trigger structure 511 and the second snap-fit ​​structure 512 are respectively disposed on opposite sides of the body 510 and are integrally molded with the body 510. Preferably, it is injection molded from high-strength engineering plastic to ensure that it maintains operational stability and durability under frequent operation.

[0062] Furthermore, the second elastic element 520 is horizontally disposed between the body 510 and the outer wall of the first guide channel 212. One end of the second elastic element abuts against the inner wall of the body 510 facing the first guide channel 212, and the other end abuts against the outer wall of the first guide channel 212, providing a reset elastic force for the trigger assembly 500. When the flip cover 300 pushes the trigger structure 511 to move the body 510 laterally, the second elastic element 520 is compressed and stores energy. When the flip cover 300 closes again and the external force is removed, the second elastic element 520 releases its elastic potential energy, driving the body 510 to automatically reset to its initial position, ensuring that the trigger assembly 500 can accurately return to its original position after each operation, and ensuring the repeatability and reliability of subsequent actions.

[0063] Furthermore, the main body 510 has a U-shaped structure with two sliding arms 513 that are movably engaged within the second guide channel 213. This U-shaped structure has good elastic deformation capacity and bending stiffness, enabling it to maintain stable movement under lateral force, while effectively absorbing assembly errors and instantaneous impact forces.

[0064] Preferably, two second locking structures 512 are provided, corresponding to one end of the two sliding arms 513 near the first guide channel 212, and engaging one-to-one with the two protrusions of the first locking structure 410 on the straw 400. This design ensures that the locking force on the straw 400 is evenly distributed, significantly improving locking stability and preventing the straw 400 from accidentally popping up due to unilateral disengagement, further enhancing safety and structural reliability.

[0065] In this embodiment, the flip cover 300 is mainly used to control the switching of drinking modes and the sealing and protection of the bottle mouth. It is rotatably connected to the first outer cover 220 of the main cover 200 and has a closed position and a fully open position. When the flip cover 300 rotates from the closed position to the fully open position to a first angle, its outer wall abuts against the trigger structure 511 of the trigger component 500 and pushes it to move laterally, thereby causing the second snap-fit ​​structure 512 to separate from the first snap-fit ​​structure 410 on the straw 400, so that the straw 400 is lifted under the action of the first elastic member 420, and the drinking mode of the straw 400 is activated; when the flip cover 300 is in the closed position, its inner wall presses against the top of the straw 400, driving the straw 400 to overcome the elastic force of the first elastic member 420 and descend to the storage state, completing the reliable return and sealing of the straw 400.

[0066] Furthermore, when the flip cap 300 is in the closed position, its inner wall simultaneously abuts against and tightly seals the drinking spout 211 and the top of the straw 400, achieving a dual-channel seal and effectively preventing liquid leakage and external contaminants from entering the bottle. When the flip cap 300 is rotated from the closed position to the second angle, the inner wall of the flip cap 300 detaches from the drinking spout 211, exposing and opening it for direct pouring and drinking by the user. At this time, the straw 400 remains in the retracted state and is not triggered to lift. This design enables independent and step-by-step switching between the direct drinking mode and the straw 400 mode, meeting drinking needs in different scenarios.

[0067] Furthermore, the second angle is smaller than the first angle. Preferably, the first angle is 170°-180°, corresponding to the activation range of the straw 400 drinking mode, ensuring that the straw 400 is only triggered to rise when the flip cover 300 is rotated to a larger opening, avoiding accidental operation; the second angle is 90°-160°, corresponding to the opening range of the direct drinking spout 211, ensuring that the user can use the direct drinking function first when the spout is opened at a small angle, without needing to activate the straw 400, improving the flexibility and hygiene of use.

[0068] Furthermore, the flip cover 300 includes a second inner cover 310 and a second outer cover 320. One side of the second inner cover 310 is hinged to the first outer cover 220, and the other side is engaged with the first outer cover 220. The second outer cover 320 is horizontally movably disposed on the second inner cover 310 and has a first movable position (unlocked position) and a second movable position (locked position). When the second outer cover 320 moves to the first movable position, it allows the second inner cover 310 to rotate around the hinge point to open the flip cover 300. When the second outer cover 320 moves to the second movable position, it restricts the rotation of the second inner cover 310 to prevent accidental opening, which is especially suitable for child-proof leak prevention or accidental touch prevention scenarios.

[0069] Furthermore, the second outer cover 320 is provided with a second locking part 321 corresponding to and engaging with the first locking part 225, thereby achieving a stable lock when the flip cover 300 is closed. The second inner cover 310 is also provided with a horizontally arranged guide part 311, and the second outer cover 320 is provided with a sliding part 322 slidably connected to the guide part 311, the two forming a linear sliding pair. The guide part 311 can restrict the sliding part 322 from moving vertically, ensuring that the second outer cover 320 slides smoothly only in the horizontal direction, preventing shaking or dislodgement. When the second outer cover 320 moves along the guide part 311 to the first moving position, the first locking part 225 separates from the second locking part 321, achieving unlocking; when the second outer cover 320 moves along the guide part 311 to the second moving position, the first locking part 225 and the second locking part 321 remain engaged, achieving automatic locking.

[0070] Furthermore, the second inner cover 310 is provided with a mounting groove 312 arranged along the moving direction of the second outer cover 320, and a third elastic element 313, preferably a compression spring, is provided in the mounting groove 312. The second outer cover 320 is provided with a driving part 323 that engages with the mounting groove 312 and abuts against the end of the third elastic element 313. When the second outer cover 320 is moved towards the first moving position along the guide part 311 by an external force, the driving part 323 can compress the third elastic element 313 to store energy. When the external force applied to the second outer cover 320 disappears, the third elastic element 313 releases its elastic potential energy, pushing the driving part 323 to reset, thereby driving the driving part 323 to move the second outer cover 320 towards the second moving position along the guide part 311. This not only simplifies the operation process but also ensures that the flip cover 300 can automatically return to the locked state after each closing, significantly improving the product's safety, convenience, and user experience.

[0071] Furthermore, the second inner cover 310 is provided with a third sealing element 720 on the side facing the first outer cover 220. The third sealing element 720 is a rubber gasket fixed to the inner surface of the second inner cover 310. It includes two sealing parts with a height difference, wherein the higher sealing part corresponds to the top of the straw 400 and the lower sealing part corresponds to the drinking spout 211. When the flip cover 300 is in the closed position, the two sealing parts sequentially form an interference fit with the top of the straw 400 and the edge of the drinking spout 211, realizing a double independent seal for the straw 400 channel and the drinking channel.
