The shape of cover body 2 is matched with cup body 1, which can be tightly connected with cup body 1 to prevent liquid leakage. Diaphragm 3 is made of material with anti-pollution and heat sealing performance, such as polytetrafluoroethylene (PTFE) or other high-performance plastic film. The thickness of diaphragm 3 should be moderate, which can ensure good sealing performance and will not affect the opening and closing of the cover. Diaphragm 3 is arranged on cover body 2 and can be fixed by pasting, hot pressing or other ways. When cover body 2 is connected with cup body 1, diaphragm 3 is tightly abutted with the top of cup body 1 to form a seal. In the embodiment, cup body 1 is set with a specific formula, so that the maximum temperature resistance of cup body 1 can reach 135 DEG C, which can meet the current most liquid food. Within 135 DEG C, the cup does not soften, and there is no risk of food safety.

[0044] Further, the cup body 1 has a containing space 11 with a third opening 12, the containing space 11 is used to hold liquid, the clamping protrusion 4 is arranged on the cup body 1 and located at the third opening 12, and the cover body 2 is clamped on the clamping protrusion 4.

[0045] In this embodiment, the containing space 11 of the cup body 1 holds various liquids. The third opening 12 is located at the top of the cup body 1, and its size and shape match the cover body 2, ensuring that the cover body 2 can be tightly clamped on the cup body 1. The clamping protrusion 4 is arranged at the third opening 12 of the cup body 1 in a ring shape. The height and width of the clamping protrusion 4 are moderate, which can ensure the firmness of the clamping of the cover body 2 and will not affect the opening and closing of the cover body 2. The clamping protrusion 4 is made of the same material as the cup body 1 and is integrally formed by injection molding. Its surface can be treated to prevent slipping, increasing the friction when the cover body 2 is clamped.

[0046] The edge of the cover body 2 is designed with a groove matching the clamping protrusion 4, so that the cover body 2 can be accurately clamped on the cup body 1. When the cover body 2 is clamped on the cup body 1, the clamping protrusion 4 tightly matches the groove of the cover body 2, forming a seal. This clamping method is simple and reliable, which can effectively prevent liquid leakage.

[0047] The clamping protrusion 4 makes the connection between the cover body 2 and the cup body 1 more tightly, effectively preventing liquid leakage. Whether carrying the cup outside or in the process of use, it can ensure that the liquid will not spill out, improving the practicality and safety of the cup. Good sealing can also prevent external dust, bacteria and other pollutants from entering the cup, keeping the liquid clean and sanitary. The clamping method of the cover body 2 and the cup body 1 is simple and fast, and the user can easily open and close the cup. Without the need for additional tools or complex operations, it is convenient for users in daily use. The design of the clamping protrusion 4 makes the cover body 2 have a certain guiding effect when clamping, so that the user can more accurately install the cover body 2 on the cup body 1, improving the convenience of use.

[0048] Further, the clamping protrusion 4 and the cup body 1 form a clamping gap 41, and the cover 21 is clamped on the clamping protrusion 4; the push rod 22 has a plurality of push rods 22 and is slidably arranged on the cover 21, and the diaphragm 3 is arranged on the push rod 22.

[0049] In this embodiment, the clamping protrusion 4 is integrally formed with the cup body 1 and located at the opening of the cup body 1. The height and width of the clamping protrusion 4 are designed according to actual needs to ensure firm and reliable clamping with the cup cover 21. The clamping gap 41 formed between the clamping protrusion 4 and the cup body 1 has a moderate width, which can facilitate the clamping of the diaphragm 3 and ensure good sealing. The number of push rods 22 can be selected according to actual needs, and generally 3 to 6 are provided on the cup cover 21 at intervals along the circumference. One end of the push rod 22 is provided with an operating handle to facilitate the user to push the push rod 22. The other end is connected with the diaphragm 3, and by pushing the push rod 22, the diaphragm 3 can be clamped into the clamping gap 41 to achieve sealing. Even if liquid leaks between the cup cover 21 and the cup body 1, the diaphragm 3 clamped in the clamping gap 41 can also prevent liquid from leaking out, and the liquid will temporarily exist between the diaphragm 3 and the cup body 1.

[0050] By clamping the diaphragm 3 into the clamping gap 41 through the push rod 22, a more airtight seal can be achieved. The elastic material of the diaphragm 3 can tightly fit with the cup body 1 and the clamping protrusion 4, effectively preventing liquid leakage and ensuring the safety of the liquid in the cup. The user only needs to gently push the push rod 22 to achieve the clamping and sealing of the diaphragm 3, which is simple and convenient to operate. Compared with the traditional sealing method, it does not need to use complex tools or perform tedious operations, improving the convenience of use.

[0051] Further, the push rod 22 has a first protrusion, and after the push rod 22 slides, the first protrusion is used to clamp into the clamping gap 41.

[0052] In this embodiment, a first protrusion is provided at one end of the push rod 22 close to the diaphragm 3, and the size of the first protrusion is slightly larger than the width of the clamping gap 41, so as to be firmly clamped in the clamping gap 41. The first protrusion is integrally formed with the push rod 22, ensuring the stability and reliability of the structure.

[0053] The clamping design of the first protrusion can further enhance the sealing effect on the basis of the sealing of the diaphragm 3. The first protrusion clamped in the clamping gap 41 can effectively prevent the push rod 22 from sliding accidentally, thereby ensuring that the diaphragm 3 always maintains tight abutment with the cup body 1 and improving the reliability of the sealing. Even in the case of external pressure or vibration of the cup, the first protrusion can be firmly clamped in the clamping gap 41 to prevent liquid leakage and ensure the safety of the liquid in the cup. The user only needs to perform a simple pushing operation to achieve the sliding of the push rod 22 and the clamping of the first protrusion, which is very simple to operate. Without the need to use complex tools or perform tedious operation steps, the convenience of use is improved.

[0054] Further, the diaphragm 3 has a first opening 31, and the cup cover 21 has a second opening 23, and the first opening 31 leads to the second opening 23.

[0055] In this embodiment, the first opening 31 is arranged at the edge of the diaphragm 3, and the thickness of the diaphragm 3 is moderate, which can ensure good sealing performance and will not affect the pushing of the push rod 22. The second opening 23 is arranged at the edge of the cup cover 21, and the first opening 31 can lead to the second opening 23. The second opening 23 is used for liquid outlet.

[0056] When it is needed to drink the liquid in the cup, the user can insert a straw through the second opening 23 on the cup cover 21 or directly drink. Since the first opening 31 of the diaphragm 3 leads to the second opening 23, the liquid can flow out smoothly without being hindered by the diaphragm 3.

[0057] The first opening 31 of the diaphragm 3 leads to the second opening 23 of the cup cover 21, so that the user can directly drink the liquid in the cup or insert a straw to drink through the opening on the cup cover 21. This design is convenient for the user to use, and the user can easily drink the liquid without opening the cup cover 21. Especially in some occasions such as driving, working, etc., the user can conveniently drink the liquid in the cup without affecting other activities. Good sealing performance can also prolong the storage time of the liquid, especially for some perishable liquids such as milk, juice, etc., the importance of sealing performance is more prominent.

[0058] Further, the lifting piece 5 has a through hole 51, the lifting piece 5 is arranged on the cup cover 21 and located in the first opening 31, and the through hole 51 is used for liquid outlet after the lifting piece 5 is lifted and interference fits with the first opening 31.

[0059] In this embodiment, the outer diameter of the lifting piece 5 is slightly larger than the diameter of the first opening 31 of the diaphragm 3, so as to realize interference fit with the first opening 31 after being lifted. The center of the lifting piece 5 is provided with a through hole 51, and the diameter of the through hole 51 is designed according to the actual liquid outlet requirement, so as to ensure smooth liquid flow and no liquid residue.

[0060] The design of the lifting piece 5 is convenient for the user to use in different occasions, and the lifting piece 5 will not be contaminated by dust after being lowered, and is cleaner than the current injection cup. When drinking liquid, the lifting piece 5 is lifted, and when interrupting drinking, the lifting piece 5 is lowered to keep clean. The interference fit of the lifting piece 5 with the first opening 31 after being lifted can further enhance the sealing performance of the cup.

[0061] Further, the plug 6 is sleeved on the cup cover 21 and is used for clamping the lifting piece 5, and after clamping, the plug 6 drives the lifting piece 5 to lift and lower, and the plug 6 is used for plugging the through hole 51.

[0062] In this embodiment, the inner diameter of the plug 6 is slightly larger than the outer diameter of the cup cover 21, so that the plug 6 can be sleeved on the cup cover 21. The bottom of the plug 6 is provided with a clamping structure matched with the lifting piece 5, which can be clamped on the lifting piece 5 firmly.

[0063] First, the lifting piece 5 is installed in the through hole 51 on the cup cover 21, so that it can be freely lifted. Then, the plug 6 is sleeved on the cup cover 21, so that the top of the plug 6 is clamped together with the lifting piece 5.

[0064] When the cup needs to be used, the user can lift the plug 6 upwards to drive the lifting piece 5 to rise. The lifting piece 5 is in interference fit with the first opening 31, and the lifting piece 5 will not slide out of the first opening 31. The plug 6 is separated from the lifting piece 5, and the liquid can flow out through the liquid outlet hole. When the cup does not need to be used, the user can press the plug 6 downwards to drive the lifting piece 5 to descend, so that the liquid cannot flow out. The setting of the plug 6 can further enhance the sealing performance of the cup. The plug 6 is sleeved outside the lifting piece 5, which can keep the lifting piece 5 clean.

[0065] Further, the mounting block 7 is arranged on the cup cover 21, and the plug 6 is clamped on the mounting block 7 after being separated from the lifting piece 5.

[0066] In this embodiment, the mounting block 7 is provided with a clamping structure which is matched with the plug 6 and can firmly clamp the plug 6. The mounting block 7 provides a special storage position for the plug 6. When the plug 6 is separated from the lifting piece 5, it can be clamped on the mounting block 7, thereby avoiding the problem that the plug 6 is easily lost due to random placement. In this way, the user can use the cup more confidently without worrying about the sealing performance of the cup being affected by the loss of the plug 6.

[0067] Further, one end of the baffle 8 is arranged on the diaphragm 3, and one end of the control rod 9 is arranged on the lifting piece 5 and the other end is arranged on the other end of the baffle 8. The lifting piece 5 drives the control rod 9 to rise and fall, and the control rod 9 is used to drive the other end of the baffle 8 to abut against the cup body 1, and the second opening 23 is closed after abutting.

[0068] In this embodiment, one end of the baffle 8 is firmly fixed on the diaphragm 3 by means of adhesive or hot melting. The thickness of the baffle 8 is moderate, which can ensure good sealing performance when the second opening 23 is closed, and will not affect the movement of the control rod 9. The control rod 9 can be made of plastic and has a certain strength and rigidity. When the lifting piece 5 rises, the control rod 9 rises together. The other end of the control rod 9 pulls the baffle 8, so that the other end of the baffle 8 gradually moves away from the diaphragm 3 and the cup body 1 to open the second opening 23.

[0069] On the contrary, when the lifting piece 5 descends, the control rod 9 also descends, and the control rod 9 drives the baffle 8 to gradually return to the initial position, so that the second opening 23 is closed again.

[0070] The baffle 8 can abut against the cup body 1 to close the second opening 23 under the driving of the control rod 9, and in combination with the sealing effect of the diaphragm 3 and the lifting piece 5, a double sealing guarantee is provided for the injection molded cup. This design greatly improves the sealing performance of the cup, effectively preventing liquid leakage, and ensuring that the liquid will not spill out, whether during carrying or in the case of tilting, inversion, etc. The control rod 9 and the baffle 8 also facilitate the user to drink the beverage.
