[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] This utility model provides a pre-venting anti-spray cup lid for use in water cups. The specific structure and function of the pre-venting anti-spray cup lid provided by this utility model will be described below with reference to the text and accompanying drawings.

[0023] Reference Figures 1 to 5 The pre-venting and anti-spray cup lid provided according to an embodiment of the present invention includes: a lid body 100 and a flip-top assembly 200. The lid body 100 is made of common plastic material, and its top is provided with a water outlet 110 and a vent 120. The water outlet 110 is used for the user to drink the liquid in the cup, and the vent 120 is used to expel the gas in the cup that expands due to the hot beverage.

[0024] The flip-top assembly 200 includes a first flip flap 210, an exhaust seal 220, a second flip flap 230, a water outlet seal 240, and an elastic element 250. The rear end of the first flip flap 210 is rotatably connected to the middle of the cover body 100, and the front end is detachably connected to one edge of the cover body 100. This ensures that the first flip flap 210 can rotate and is tightly connected to the cover body 100 when closed. The exhaust seal 220 is a columnar structure made of rubber or silicone, fixedly disposed on the surface of the first flip flap 210 near the cover body 100, and corresponds to the position of the exhaust hole 120 on the cover body 100. When the first flip flap 210 is in the closed state, the exhaust seal 220 tightly abuts against the exhaust hole 120, thus providing a sealing effect.

[0025] One end of the second flap 230 is rotatably connected to the middle position of the first flap 210. A water outlet seal 240 is disposed on the side surface of the second flap 230 near the cover 100 and corresponds to the position of the water outlet hole 110 on the cover 100. In the initial state, the water outlet seal 240 tightly abuts against the water outlet hole 110 to prevent liquid from flowing out of the cup. An elastic member 250 is disposed between the first flap 210 and the second flap 230.

[0026] When a user wants to drink a hot beverage from the cup, they first hold the detachable end of the first flap 210 and rotate it backward to the first position. During this process, the vent seal 220 gradually separates from the vent hole 120 as the first flap 210 rotates, allowing the gas that has expanded due to the hot beverage to escape through the vent hole 120. Because the second flap 230 can rotate relative to the first flap 210 under the elastic force of the elastic member 250, the water outlet seal 240 on the second flap 230 remains inside the water outlet hole 110. The vent hole 120 then releases the expanded gas from the cup without causing water to spray from the water outlet hole 110, effectively preventing liquid splashing caused by sudden changes in air pressure and ensuring user safety.

[0027] After the gas inside the cup is expelled, the user continues to rotate the first flap 210, turning it backward to the second position. Driven by the first flap 210, the second flap 230 also rotates, and the water outlet seal 240 on the second flap 230 gradually separates from the water outlet 110. At this point, the water outlet 110 opens, allowing the user to drink the hot beverage from the cup normally. The entire operation is simple and convenient, and the design of venting gas before drinking greatly improves the safety and comfort of the user when using hot beverages.

[0028] It is understandable that the rear ends of the vent seal 220 and the second flap 230 are both located at the rear end of the first flap 210. Specifically, the rear ends of the vent seal 220 and the second flap 230 are both located near the position where the first flap 210 is rotatably connected to the cover 100, so that the vent seal 220 can be separated from the vent hole 120 by rotating the first flap 210 by a small angle, and the length of the water outlet seal 240 can be reduced accordingly.

[0029] Reference Figure 4 and Figure 5 According to the embodiment of this utility model, the first flap 210 is provided with two mounting plates 211. The two mounting plates 211 are made of the same plastic material as the first flap 210 and are manufactured by an integral injection molding process. The two mounting plates 211 are arranged parallel to each other at a certain distance in the left-right direction, thereby defining a rotating mounting position. The rear end of the second flap 230 is set in the rotating mounting position and can rotate flexibly relative to the two mounting plates 211. This not only ensures the stability of the rotation of the second flap 230, but also has a compact structure that does not occupy too much space, and is also conducive to the assembly and production of the entire cup lid.

[0030] When the user operates the first flap 210 to rotate, the second flap 230 rotates smoothly within the rotating installation position, causing the vent seal 220 to separate or close from the vent hole 120, and subsequently causing the second flap 230 to rotate to separate or close the water outlet seal 240 from the water outlet hole 110, thereby completing the operation process of venting first to prevent spraying and normal drinking, providing users with a safe and convenient user experience.

[0031] According to the pre-venting anti-spray cup lid provided in this embodiment of the present invention, the first flap 210 has two spaced mounting plates 211 that define a rotating mounting position. A rotating shaft 260 is provided between these two mounting plates 211, with both ends of the rotating shaft 260 fixed to the two mounting plates 211 respectively. The second flap 230 is rotatably connected to the rotating shaft 260 through a pre-set hole, allowing the second flap 230 to rotate around the rotating shaft 260. The elastic element 250 is a torsion spring, which is also sleeved on the rotating shaft 260. One end of the torsion spring abuts against the top of the cup lid, and the other end abuts against the side of the second flap 230 facing the first flap 210.

[0032] In actual use, when the first flap 210 is in the initial closed state, the torsion spring is in a certain pre-tensioned state, providing elasticity to the second flap 230, so that the water outlet seal 240 on the second flap 230 tightly abuts against the water outlet 110, thus achieving a sealing function. When the user rotates the first flap 210 to the first position to release air, due to the elasticity of the torsion spring, the second flap 230 can rotate relative to the first flap 210, keeping the water outlet seal 240 inside the water outlet 110 to prevent liquid splashing. When the user continues to rotate the first flap 210 to the second position, the first flap 210 drives the second flap 230 to rotate together, the water outlet seal 240 separates from the water outlet 110, and the user can then drink the beverage normally.

[0033] Optionally, the elastic element 250 can also be an "Ω" shaped spring, etc., which can be set according to actual needs.

[0034] Reference Figure 5 According to the embodiment of this utility model, the pre-venting anti-spray cup lid has a receiving groove 231 on the side of the second flap 230 facing the first flap 210. The shape of the receiving groove 231 is adapted to the partial shape of the torsion spring, and its depth and width can be set according to actual needs to ensure that at least part of the torsion spring can be stably accommodated. The receiving groove 231 plays a good role in positioning and limiting the torsion spring, and can effectively prevent the torsion spring from shifting or shaking during use.

[0035] During the user's operation of the cup lid for drinking, when the first flap 210 rotates, causing the second flap 230 to rotate relative to it, the interaction between the torsion spring and the second flap 230 is more stable and reliable because the torsion spring is located within the receiving groove 231. When the first flap 210 rotates to the first position to release air, the torsion spring uses its elasticity to keep the second flap 230 in the appropriate position, allowing the water outlet seal 240 to be stably positioned within the water outlet hole 110. When the first flap 210 continues to rotate to the second position, causing the water outlet seal 240 to separate from the water outlet hole 110, the torsion spring within the receiving groove 231 can still stably provide elasticity, ensuring the smoothness and stability of the entire rotation process.

[0036] It is understandable that having at least part of the torsion spring within the receiving groove 231 can also improve the compactness of the structure between the first flap 210 and the second flap 230, thereby increasing the utilization of space.

[0037] Reference Figure 4 According to the embodiments of this utility model, a pre-venting and anti-spray cup lid is provided with a reinforcing rib 212 between the mounting plate 211 and the wall surface of the first flap 210. The reinforcing rib 212 is made of the same plastic material as the mounting plate 211 and is manufactured simultaneously with the mounting plate 211 through an integrated injection molding process, ensuring the integrity and stability of the structure. The reinforcing rib 212 is approximately triangular in shape, possessing high structural strength and stability, and effectively dispersing stress. Its number is rationally set according to the actual stress conditions and structural requirements, with multiple ribs evenly distributed at the connection edge between each mounting plate 211 and the wall surface of the first flap 210. One end of the reinforcing rib 212 is tightly connected to the mounting plate 211, and the other end is firmly bonded to the wall surface of the first flap 210, forming a stable support structure. This greatly improves the durability and reliability of the cup lid and extends its service life.

[0038] Reference Figures 1 to 5 According to the embodiments of this utility model, the top of the lid body 100 is provided with a storage groove 130 arranged in a front-to-back direction. The storage groove 130 is integrally formed on the top of the lid body 100 by a molding process. Its shape is adapted to the overall outline of the flip-top assembly 200, specifically a rectangular groove structure. The depth and width can be set according to actual needs. While ensuring that the flip-top assembly 200 can be fully accommodated, it will not occupy too much space, ensuring the overall aesthetics and compactness of the lid. The flip-top assembly 200 is entirely set in the storage groove 130. In actual use, when the lid is in the initial closed state, the flip-top assembly 200 is completely stored in the storage groove 130, flush or basically flush with the top surface of the lid body 100, making the overall appearance of the lid neat and beautiful, without any protrusions or unevenness, making it convenient to carry and store.

[0039] Reference Figure 4 and Figure 5 According to the pre-venting anti-spray cup lid provided in this embodiment of the utility model, the two side walls of the storage groove 130 are provided with shaft holes 140. The shaft holes 140 are located in the upper middle part of the side wall of the storage groove 130, which ensures both the flexibility of the rotation of the first flap 210 and the uniform force on the overall structure. At the same time, the two sides of the first flap 210 corresponding to the storage groove 130 are also provided with rotating columns. The rotating columns and the first flap 210 are made by integral injection molding process, which ensures the connection strength and stability between the two. The diameter of the rotating column matches the diameter of the shaft hole 140 on the side wall of the storage groove 130, and its length is slightly longer than the thickness of the side wall of the storage groove 130 to facilitate installation and rotation. During installation, the rotating columns on both sides of the first flap 210 are aligned with the shaft holes 140 on the two side walls of the storage groove 130, and then an appropriate external force is applied to make the rotating columns pass through the corresponding shaft holes 140. After passing through, the rotating columns can rotate within the shaft holes 140.

[0040] In actual use, when the user operates the first flap 210 to rotate, the rotating column rotates smoothly within the shaft hole 140, causing the first flap 210 to perform a circular motion around the center of the shaft hole 140. This makes the rotation process of the first flap 210 more stable and reliable, without any jamming or deviation, thus ensuring the normal use of the entire pre-venting anti-spray cup cover.

[0041] Reference Figures 1 to 5 According to the embodiment of this utility model, the pre-venting anti-spray cup lid has a storage groove 130 extending through the lid body 100 in the front-to-back direction. On both sides of the storage groove 130, locking blocks 150 are integrally formed using a mold. The locking blocks 150 are wedge-shaped to facilitate the smooth engagement of the first flip piece 210 during rotation. The locking blocks 150 are positioned near the rear end of the storage groove 130, and the specific distance from the rear edge of the storage groove 130 is precisely set according to the actual requirements when the first flip piece 210 rotates to the third position.

[0042] When the user rotates the first flap 210 backward, its sides gradually approach the locking blocks 150 on both sides of the storage slot 130. When the first flap 210 rotates to the third position, the edges of its sides are in contact with the front end of the locking block 150. Continuing to apply rotational force, the wedge-shaped surface of the locking block 150 guides the sides of the first flap 210 to smoothly engage in the slots 160 formed between the locking block 150 and the side wall of the storage slot 130, thus achieving the locking of the locking block 150 onto the sides of the first flap 210. This effectively prevents the first flap 210 from rotating accidentally in the third position, ensuring the stability of the cup lid in a specific state.

[0043] When it is necessary to release the latch, the user only needs to apply a forward external force to push the first flap 210. Due to the wedge-shaped design of the latch 150, the first flap 210 can be easily disengaged from the latch 150 and restored to a freely rotatable state for subsequent rotational closure.

[0044] Reference Figures 2 to 5 According to the embodiment of this utility model, the pre-venting anti-spray cup lid has a snap-fit ​​edge 213 formed on the front side of the first flap 210 through an integral molding process. The snap-fit ​​edge 213 is arc-shaped and is set around the front edge of the first flap 210. Its width and thickness are reasonably designed to ensure sufficient strength without affecting the overall appearance and operational flexibility of the first flap 210.

[0045] A buckle 214 is provided on the rear side of the snap-fit ​​edge 213. The buckle 214 is made of plastic and is integrally molded with the first flap 210. Its shape is a raised structure with barbs. At the same time, a groove 160 is molded in the corresponding position on the front side of the lid 100. The shape and size of the groove 160 are adapted to the buckle 214, and its depth and width have been precisely calculated to ensure that the buckle 214 can be firmly locked in the groove 160. When the user closes the first flap 210, the buckle 214 will smoothly engage in the groove 160, realizing a reliable connection between the first flap 210 and the lid 100, preventing the first flap 210 from opening accidentally, and ensuring the sealing of the lid.

[0046] Reference Figure 4 and Figure 5 According to the embodiments of this utility model, the pre-venting anti-spray cup lid includes a water outlet seal 240 comprising a plunger and at least two sealing edges. The plunger is made of food-grade silicone, possessing good elasticity and sealing performance. At least two sealing edges are spaced apart along the length of the plunger. In this embodiment, two sealing edges are specifically provided. These two sealing edges are also made of food-grade silicone and are integrally molded with the plunger. The outer peripheral wall of the sealing edge is arc-shaped, with a diameter slightly larger than the inner diameter of the water outlet 110. When the water outlet seal 240 is installed inside the water outlet 110, the outer peripheral walls of at least two sealing edges will tightly abut against the inner peripheral wall of the water outlet 110, forming multiple sealing lines. This effectively prevents liquid leakage from the water outlet 110 when not in a drinking state, improving the sealing effect of the cup lid. When the user opens the first flap 210 to drink water, the water outlet seal 240 will separate from the water outlet 110 as the first flap 210 rotates, so that water can be dispensed normally. After drinking water, the user closes the first flap 210, and the water outlet seal 240 returns to the water outlet 110, restoring the sealing state.

[0047] An embodiment of this utility model also provides a water cup, including a straw and a cup lid with pre-venting anti-spray as provided in the embodiment of this utility model, with the straw connected to a water outlet 110. The specific structure of the pre-venting anti-spray cup lid is as described in the above embodiments. Since this water cup adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
