[0002] A drinking cup is a container used to hold liquids (such as water, tea, beverages, etc.) and for easy drinking.

[0003] Currently, in reality, as toddlers transition from drinking from bottles to drinking from sippy cups and then to using cups, their limbs may move uncontrollably during the learning process, easily causing them to knock over the cup and spill water. When passengers in vehicles are moving, especially on uneven roads, they often encounter situations where water spills onto their face, body, and the vehicle due to potholes, and the liquid may flow into their nostrils or cause choking.

[0004] In addition, in similar drinking cups on the market, the sealing valve is in direct contact with the water inside the cup. After drinking, some water in the mouth will flow back into the cup through the lips. If too much time is left before drinking, it will cause secondary contamination, which is extremely unhygienic.

[0005] Therefore, there is a need to provide a double-walled, spill-proof drinking cup in order to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a double-layer anti-overflow drinking cup, which adopts double-layer water sealing technology, achieving a leak-proof effect during use and solving the problem of easy leakage caused by accidental tipping over of similar cups on the market.

[0007] To achieve the above-mentioned utility model objectives, a double-layered anti-overflow drinking cup is provided, comprising a cup body, a cup mouth connector, a silicone sealing ring, and a silicone anti-leak valve; The cup mouth connector is threaded to the cup mouth of the cup body and is sealed by a silicone sealing ring; The upper part of the cup mouth connector has a flared, inclined cup mouth wall; The bottom of the inclined wall of the cup mouth extends horizontally inward to form an annular support part, and the annular support part is evenly provided with a plurality of water outlet holes.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figure 1 and Figure 2 As shown, a double-walled anti-overflow drinking cup according to this embodiment includes a cup body 1, a cup mouth connector 2, a silicone sealing ring 3, and a silicone anti-leak valve 4.

[0019] The cup mouth connector 4 is threaded to the cup mouth of the cup body 1 and is sealed by the silicone sealing ring 3.

[0020] In this embodiment, as Figure 3 As shown, the lower inner wall of the cup mouth connector 3 has an internal thread 5, such as... Figure 4 As shown, the top sidewall of the cup body 1 has an external thread 6, and the cup mouth connector 2 is connected to the cup body 1 through the engagement of the internal thread 5 and the external thread 6.

[0021] like Figure 3 and Figure 5 As shown, the upper part of the cup mouth connector 2 has a flared, inclined cup mouth wall 7; as Figure 4 As shown, the bottom of the inclined wall 7 of the cup mouth extends horizontally inward to form an annular support part 8, and the annular support part 8 is evenly provided with a plurality of water outlet holes 9; the annular support part 8 has a connecting support beam 10 between two adjacent water outlet holes 9; the inner wall of the annular support part 8 extends downward to form a conical support ring 11.

[0022] like Figure 6 and Figure 7As shown, the silicone leak-proof valve 4 includes a horizontal sealing ring 12, a conical sealing ring 13, and a vertical sealing ring 14. The horizontal sealing ring 12 is trumpet-shaped and adapts to the inclined wall 7 of the cup opening. A plurality of spherical support protrusions 15 are arranged in a circular array on the outer wall of the horizontal sealing ring 12. The conical sealing ring 13 is located inside the horizontal sealing ring and connected to the bottom of the horizontal sealing ring 12. The conical sealing ring 13 has a bottom, and a normally closed return valve 16 is located at the center of the bottom of the conical sealing ring 13. The conical sealing ring 13 fits against the inner wall of the conical support ring 11, and the bottom of the conical sealing ring 13 extends out of the conical support ring 11.

[0023] In this embodiment, a slit is cut at the bottom center of the conical sealing ring 13 to form a normally closed return valve 16.

[0024] In this embodiment, the lower part of the outer wall of the conical sealing ring 13 has a sealing step portion 17; when the conical sealing ring 13 is attached to the inner wall of the conical support ring 11, and the bottom of the conical sealing ring 13 extends out of the conical support ring 11; the sealing step portion 17 plays a good limiting role, so that the conical sealing ring 13 will not detach from the conical support ring 11.

[0025] The vertical sealing ring 14 is located at the lower part of the outer wall of the horizontal sealing ring 12, and the conical sealing ring 13 is located inside the vertical sealing ring 14; the vertical sealing ring 14 matches the lower part of the inclined wall 7 of the cup mouth.

[0026] In this embodiment, the lower part of the inclined wall 7 of the cup mouth is provided with a plurality of arc-shaped protrusions 18 in a circular array; an annular elastic part 19 is provided between the transverse sealing ring 12 and the conical sealing ring 13; with this configuration, when the mouth sucks on the outside of the transverse sealing ring 12, the force of the lips causes the spherical support point 15 on the inside of the transverse sealing ring 12 to contact the inner inclined surface of the inclined wall 7 of the cup mouth, and the second layer of water sealing joint opens first. At the same time, the annular elastic part 19 changes shape and deviates towards the direction of the lip force, and at the same time, the top of the vertical sealing ring 14 presses down and connects to the support beam 10 and stops moving downward. At the same time, the outside of the vertical sealing ring 14 contacts the arc-shaped protrusions 18, and the suction force forces the top of the vertical sealing ring 14 to open towards the center point of the cup mouth, and the first layer of water sealing joint opens, and the water in the cup smoothly enters the mouth. By continuously sucking, the drinking effect is achieved.

[0027] In this embodiment, a dust cover 20 is fitted onto the cup mouth connector 2 to prevent dust.

[0028] In addition, the cup body 1 is also equipped with a handle (not shown in the figure) to facilitate the user's grip on the cup body.

[0029] Working principle: (e.g.) Figure 8As shown, the cup body 1 is assembled with the cup mouth connector 2, and the silicone sealing ring 3 achieves a sealing effect. The silicone anti-leak valve 4 is installed in the cup mouth connector 2. The sealing step part 17 is installed on the top of the conical support ring 11. The two are tightly connected. The vertical sealing ring 14 simultaneously matches the lower inner side of the cup mouth inclined wall 7, achieving the first layer of water sealing effect inside the cup. The inner side of the other end of the cup mouth inclined wall matches the inner side of the horizontal sealing ring, achieving the second layer of sealing and anti-overflow effect. Using the lever principle, when the mouth sucks on the outside of the horizontal sealing ring 12, the force of the lips causes the spherical support point 15 on the inside of the horizontal sealing ring 12 to contact the inner inclined surface of the cup mouth 7. The second layer of water sealing joint opens first. At the same time, the annular elastic part 19 changes shape and deviates towards the direction of the lip force. Simultaneously, the top of the vertical sealing ring 14 is pressed down to contact the connecting support beam 10 and stops moving downward. At the same time, the outside of the vertical sealing ring 14 contacts the arc-shaped protrusion 18. The suction force forces the top of the vertical sealing ring 14 to open towards the center point of the cup mouth. The first layer of water sealing joint opens, and water in the cup smoothly enters the mouth. Continuous sucking achieves the effect of drinking water. When a certain negative pressure is generated in the cup, the normally closed return air valve 16 automatically opens to allow air in, thereby obtaining the best drinking effect. When sucking stops, the vertical sealing ring 14 and the horizontal sealing ring 12 return to their original shape, achieving an immediate water sealing state. The function of the annular elastic part 19 is to make the vertical sealing ring 14 and the horizontal sealing ring 12 more easily deform and open during sucking, so as to achieve an easy drinking effect.
