Description

Technical Field

[0001] This utility model belongs to the field of water cup technology, specifically relating to a leak-proof flip-top water cup that prevents accidental opening. Background Technology

[0002] With improved living standards and increased health awareness, reusable water bottles, especially those with straws, have become widely used in daily life, travel, sports, and children's products. These bottles typically consist of a body, a lid threaded onto the rim, and a straw mounted on the lid. To prevent the straw from being exposed to air, avoiding dust and bacterial contamination, and maintaining hygiene at the straw opening, most products have a hinged flap on the threaded lid.

[0003] Currently, most flip-top straw cups on the market rely on simple button fasteners or snap-fit ​​mechanisms to lock the lid. Users close the lid by pressing down on a snap-fit ​​mechanism at the end of the flip, which engages with the corresponding structure on the threaded cap. While this structure is simple, its locking reliability is insufficient in actual use. During carrying or transportation, accidental impacts or pressing of the button can easily cause the lid to pop open, leading to liquid leakage and exposing the straw opening to external contaminants, posing significant hygiene and safety hazards. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a leak-proof flip-top cup that prevents accidental opening. It has a reasonable design, strong practicality, and simple and reliable structure. Through the sliding locking component, the button fastener can be physically limited after the flip-top is closed, making it impossible to press down, effectively preventing accidental opening, greatly improving the safety and reliability of the product, and realizing double locking of the flip-top closed state. When it is necessary to press the button to release the flip-top, simply slide the locking component to unlock it, and then press to open the lid. It is convenient and simple to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A leak-proof flip-top cup designed to prevent accidental opening includes a cup body and a threaded cap. The threaded cap is screwed tightly onto the cup body, and a sealing ring is provided between the threaded cap and the cup body's rim. A suction nozzle is provided on the threaded cap. A flip cover is provided on the threaded cap, with one end hinged to the threaded cap and the other end fastened to the threaded cap via a button fastener. The end of the flip cover that is hinged to the threaded cap is the hinged end, while the other end is the free end. A locking element is provided on the flip cover, which is slidably mounted on the flip cover. The locking element restricts the button fastener, locking the flip cover in the closed state. When opening the flip cover, first slide the locking element to release the restriction on the button fastener, then press the button fastener to release the flip cover.

[0006] Furthermore, a pull ring handle is provided on the top of the threaded cap. The pull ring handle is fixed to the threaded cap with a rubber coating. The pull ring handle includes a lifting part and a mounting part. The design of the pull ring handle makes it convenient for users to carry the water cup and facilitates practical use. The pull ring handle is fixed to the top of the threaded cap through a rubber coating injection molding process, forming an integral structure with the threaded cap, which enhances the stability and reliability of the connection between the pull ring handle and the threaded cap. The pull ring handle is made of a slightly softer material to increase the comfort of the user's grip, and the pull ring handle and the threaded cap are different colors to achieve a color-separated design.

[0007] Furthermore, the button fastener includes a button and a pin. The button is hinged to the threaded cover via the pin. A limit stop is provided on the upper part of the button, and a locking groove is provided on the top of the automatic end of the flip cover. When the flip cover is closed, the limit stop is locked and pressed into the locking groove, fastening the flip cover into the threaded cover. When the flip cover is opened, with the button disengaged from the locking mechanism, pressing the button causes the limit stop to rotate away from the flip cover, thereby releasing the restriction on the free end of the flip cover. Through the cooperation of the limit stop and the locking groove, reliable fastening of the flip cover is achieved, ensuring that the flip cover is firmly locked when closed. When it is necessary to open the flip cover, the restriction of the locking mechanism on the button must be released first, and then the button must be actively pressed to release it, effectively preventing accidental opening and improving safety.

[0008] Furthermore, a mounting hole is provided at the bottom of the button, and a silicone spring is installed inside the mounting hole. The silicone spring is always in contact with the outer wall of the threaded cover. Preferably, the outer wall of the threaded cover in contact with the silicone spring has a flat cut surface to ensure full contact with the silicone spring and optimize elasticity and stability. When the flip cover is closed, under the rebound force of the silicone spring, the limiting stop is always locked and pressed into the locking groove at the top of the free end of the flip cover. The silicone spring avoids hard contact friction between the button and the threaded cover, and the button can automatically reset under the rebound force of the silicone spring. The silicone spring provides continuous elastic rebound force, ensuring that the limiting stop is always tightly pressed into the locking groove after the flip cover is closed, enhancing the locking reliability and preventing the flip cover from loosening due to vibration or collision. Moreover, as a flexible component, the silicone spring reduces hard friction and noise between the button and the threaded cover, improving user experience and component durability.

[0009] Furthermore, the locking mechanism includes a locking block that slides and engages with the top of the flip cover. The locking block has a locking protrusion, and the top of the button has a locking groove. When the flip cover is closed, the locking block slides towards the button, limiting the movement of the locking protrusion within the locking groove, thus stopping the button. When the flip cover is opened, the locking block slides away from the button, completely removing the locking protrusion from the locking groove, and then the button is pressed to open the flip cover. This ingenious design provides a double safety mechanism. The locking block, through the engagement of the locking protrusion and the locking groove, physically restricts the button's pressing action, preventing accidental triggering and avoiding accidental opening of the flip cover. The sliding operation is simple and intuitive; users must unlock the cover before opening it, enhancing security.

[0010] Furthermore, the locking block is equipped with a limit slider, and the side of the flip cover is equipped with a limit groove. The limit slider is matched and engaged within the limit groove, and the top surface of the locking block is equipped with a force-applying protrusion. The limit groove and the limit slider work together to ensure that the locking block slides smoothly on the preset trajectory, improving structural accuracy and reliability. The force-applying protrusion provides a clear force point, making it easier for users to push and pull the locking block, enhancing the operating feel, and making the pushing and pulling operation more effortless and smooth.

[0011] Furthermore, the locking block is equipped with an arc-shaped protrusion one, and the top of the flip cover is equipped with an arc-shaped protrusion two. When the locking block is slid to the limit or release button, the arc-shaped protrusion one needs to overcome the resistance of the arc-shaped protrusion two to move from one side of the arc-shaped protrusion two to the other side. This ingenious and reasonable design provides tactile feedback and a sense of resistance, allowing the user to perceive whether the locking block is in place. When the locking block slides to the locked or unlocked position, the arc-shaped protrusion needs to overcome a resistance peak to pass through. This not only gives the user a clear indication of being in place, but also uses this resistance to stabilize the locking block in the final position, effectively preventing it from accidentally sliding due to its own weight or slight vibration, further enhancing the reliability of the safety lock function and the user experience.

[0012] Furthermore, the flip cover is equipped with a water-sealing baffle. When the flip cover is closed, the water-sealing baffle presses down on the nozzle. When the flip cover is closed, the water-sealing baffle actively presses and seals the nozzle, effectively preventing liquid from leaking from the nozzle when the cup is shaken or inverted.

[0013] Furthermore, the threaded cap is equipped with a vent hole that connects to the cup body. When the cap is closed, the sealing baffle is positioned directly above the vent hole. This ensures that when the sealing baffle presses down on the spout, the spout simultaneously presses down on the vent hole. The ingenious design means that when the cap presses down on the spout via the sealing baffle, the spout deforms and simultaneously blocks the vent hole. This allows the cap's closing action to simultaneously seal both the spout and the vent, two potential leakage points. While ensuring normal venting during drinking, it perfectly solves the leakage problem when not in use, achieving a balance between sealing performance and ease of use.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: This utility model is reasonably designed, highly practical, and has a simple and reliable structure. Through the sliding locking component, the button fastener can be physically limited after the flip cover is closed, preventing it from being pressed down and effectively preventing accidental opening. This greatly improves the safety and reliability of the product and achieves double locking of the flip cover closed state. When it is necessary to press the button to release the flip cover, simply slide the locking component to unlock it and then press the button to open the cover. The operation is convenient and simple. Attached Figure Description

Detailed Implementation

[0017] like Figures 1 to 17 As shown in the illustration, this is a first embodiment of the present invention. The present invention discloses a leak-proof flip-top cup that prevents accidental opening, including a cup body 1 and a threaded cap 2. The threaded cap 2 is screwed tightly onto the cup body 1, and a sealing ring 7 is provided between the threaded cap 2 and the cup mouth of the cup body 1 to ensure tight connection. A suction nozzle 3 is provided on the threaded cap 2. A flip cover 4 is provided on the threaded cap 2. One end of the flip cover 4 is hinged to the threaded cap 2, and the other end of the flip cover 4 is fastened to the threaded cap 2 by a button fastener 6. The end of the flip cover 4 that is hinged to the threaded cap 2 is the hinged end, and the other end is the free end. A locking member 5 is provided on the flip cover 4. The locking member 5 is slidably disposed on the flip cover 4 and is used to restrict the button fastener 6, locking the flip cover 4 in the closed state. When opening the flip cover 4, first slide the locking member 5 to release the restriction of the button fastener 6, and then press the button fastener 6 to release the flip cover 4.

[0018] The top of the threaded cap 2 is provided with a pull ring handle 8, which is fixed to the threaded cap 2 with a rubber coating. The pull ring handle 8 includes a lifting part 11 and a mounting part 12. The design of the pull ring handle 8 makes it convenient for users to carry the water bottle and facilitates practical use. The pull ring handle 8 is fixed to the top of the threaded cap 2 through a rubber coating injection molding process, forming an integral structure with the threaded cap 2, which enhances the stability and reliability of the connection between the pull ring handle 8 and the threaded cap 2. The pull ring handle 8 is made of a slightly softer material to increase the comfort of the user's grip, and the pull ring handle 8 and the threaded cap 2 are different colors to achieve a color-separated design.

[0019] The button fastener 6 includes a button 15 and a pin 16. The button 15 is hinged to the threaded cover 2 via the pin 16. A limit stop 17 is provided on the upper part of the button 15, and a clamping groove 29 is provided on the top of the automatic end of the flip cover 4. When the flip cover 4 is closed, the limit stop 17 is clamped in the clamping groove 29, fastening the flip cover 4 into the threaded cover 2. When the flip cover 4 is opened, with the button 15 disengaged from the locking member 5, pressing the button 15 causes the limit stop 17 to rotate away from the flip cover 4, thereby releasing the restriction on the free end of the flip cover 4. Through the cooperation of the limit stop 17 and the clamping groove 29, the flip cover 4 is reliably fastened, ensuring that the flip cover 4 is firmly locked when closed. When it is necessary to open the flip cover 4, the restriction of the locking member 5 on the button 15 must be released first, and then the button 15 must be actively pressed to release it, effectively preventing accidental opening and improving safety.

[0020] A mounting hole 18 is provided at the lower part of button 15, and a silicone spring 19 is provided inside the mounting hole 18. The silicone spring 19 is always in contact with the outer wall of the threaded cover 2. Preferably, the outer wall of the threaded cover 2 in contact with the silicone spring 19 is provided with a flat surface to ensure full contact with the silicone spring 19 and optimize elasticity and stability. When the flip cover 4 is closed, under the rebound force of the silicone spring 19, the limiting stop 17 is always limited and pressed into the clamping groove 29 at the top of the free end of the flip cover 4. The silicone spring 19 avoids hard contact friction between button 15 and threaded cover 2, and under the rebound force of the silicone spring 19, button 15 can automatically reset. The silicone spring 19 provides continuous elastic rebound force, ensuring that the limit stop 17 is always tightly pressed into the locking groove 29 after the flip cover 4 is closed, enhancing the locking reliability and preventing the flip cover 4 from loosening due to vibration or collision. In addition, as a flexible element, the silicone spring 19 reduces the hard friction and noise between the button 15 and the threaded cover 2, improving the user experience and component durability.

[0021] The locking component 5 includes a locking block 20, which slides and engages with the top of the flip cover 4. The locking block 20 has a locking protrusion 21, and the top of the button 15 has a locking groove 22. When the flip cover 4 is closed, the locking block 20 slides towards the button 15, limiting the movement of the locking protrusion 21 within the locking groove 22, thus restricting the button 15. When the flip cover 4 is opened, the locking block 20 slides away from the button 15, completely removing the locking protrusion 21 from the locking groove 22, and then the button 15 is pressed to open the flip cover 4. This ingenious design provides a double safety mechanism. The locking block 20, through the cooperation of the locking protrusion 21 and the locking groove 22, physically restricts the pressing action of the button 15, preventing accidental triggering of the button 15 and avoiding accidental opening of the flip cover 4. The sliding operation is simple and intuitive; the user must unlock the cover before opening it, enhancing safety.

[0022] The locking block 20 is equipped with a limiting slider 23, and the side of the flip cover 4 is equipped with a limiting groove 24. The limiting slider 23 is matched and engaged in the limiting groove 24. The top surface of the locking block 20 is equipped with a force-applying protrusion 25. The limiting groove 24 cooperates with the limiting slider 23 to ensure that the locking block 20 slides smoothly on the preset trajectory, improving the structural accuracy and reliability. The force-applying protrusion 25 provides a clear force point, making it convenient for users to push and pull the locking block 20, enhancing the operating feel, and making the pushing and pulling operation more effortless and smooth.

[0023] The locking block 20 is provided with an arc-shaped protrusion 26, and the top of the flip cover 4 is provided with an arc-shaped protrusion 27. When the locking block 20 is slid to limit or release the button 15, the arc-shaped protrusion 26 needs to overcome the resistance of the arc-shaped protrusion 27 and move from one side of the arc-shaped protrusion 27 to the other side. The design is ingenious and reasonable, providing tactile feedback and resistance, so that the user can perceive whether the locking block 20 is in place. When the locking block 20 slides to the locked or unlocked position, the arc-shaped protrusion needs to overcome a resistance peak to pass through. This not only gives the user a clear indication of being in place, but also uses this resistance to stabilize the locking block 20 in the final position, effectively preventing it from accidentally sliding due to its own weight or slight vibration, further enhancing the reliability of the safety lock function and the user experience.

[0024] The flip cover 4 is equipped with a water-sealing baffle 28. When the flip cover 4 is closed, the water-sealing baffle 28 presses down on the nozzle 3. The closing of the flip cover 4 achieves active sealing of the nozzle 3 through the water-sealing baffle 28, effectively preventing liquid leakage from the nozzle 3 when the cup is shaken or inverted. The threaded cap 2 is equipped with a vent hole 30, which is connected to the cup body 1. When the flip cover 4 is closed, the water-sealing baffle 28 is located directly above the vent hole 30. When the water-sealing baffle 28 presses down on the nozzle 3, the nozzle 3 simultaneously presses down on the vent hole 30. This ingenious design means that when the flip cover 4 presses down on the nozzle 3 through the water-sealing baffle 28, the nozzle 3 deforms and simultaneously blocks the vent hole 30 downwards. This allows the closing action of the flip cover 4 to simultaneously seal the two potential leakage points, the "sip nozzle 3" and the "vent hole 30". While ensuring normal ventilation function during drinking, it perfectly solves the leakage problem in non-use state, achieving a balance between sealing performance and ease of use.

[0025] like Figure 18 As shown, this is Embodiment 2 of the present invention. Based on Embodiment 1, the lifting part 11 of the pull ring handle 8 is adjusted. In Embodiment 1, the lifting part 11 is set horizontally, with a simple and practical style. In Embodiment 2, the lifting part 11 is set at a certain angle relative to the mounting part 12, which makes it convenient to lift and carry the water cup. The different designs of the lifting part 11 can meet the different needs of customers and realize personalized design.
