However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0037] Example 1: See Figure 1 A food storage container lid includes a lower lid 1 and a main lid 2 disposed on the lower lid 1. The main lid 2 is provided with a pressing element 3 and a release valve 4. The pressing element 3 includes a mounting groove 31 disposed on the main lid 2. A pressing key 32 is installed in the mounting groove 31. The pressing key 32 moves back and forth in the mounting groove 31. A slot 33 is provided on the inner side wall of the mounting groove 31. A locking block 34 that cooperates with the slot 33 is provided on the outer side wall of the pressing key 32. The pressing key 32 and the mounting groove 31 form a recessed airtight chamber 35. After the pressing key 32 is pressed, the locking block 34 on the pressing key 32 will slide into the corresponding slot 33. This facilitates the connection between the two during movement, ensures better normal operation of the pressing key 32, ends the welding connection between the two, facilitates disassembly and installation, and also helps to reduce production and manufacturing costs. The slot 33 on the inner wall of the mounting groove 31 is replaced with a block 34, and the block 34 on the outer wall of the pressing key 32 is replaced with a slot 33. This is just a simple change in position, and it is within the protection scope of this utility model.

[0038] Example 2: Based on Example 1, the slots 33 are evenly spaced on the inner wall of the mounting groove 31, while the blocks 34 are evenly spaced on the outer wall of the press button 32. Each block 34 corresponds to one slot 33. This arrangement facilitates more stable and secure operation of the press button 32. In this example, four slots 33 and four blocks 34 are used for ease of implementation.

[0039] Example 3: Based on Example 1 or Example 2, the pressing key 32 includes a fixed base 321 disposed in the middle of the mounting groove 31. A reset member 322 is sleeved on the fixed base 321. A button 323 is disposed on the reset member 322. A pressing shell 324 is disposed on the button 323. A decorative member 325 is disposed between the pressing shell 324 and the mounting groove 31. A locking block 34 is arranged on the outer wall of the decorative member 325. This arrangement is reasonable, and the pressing key 32 can realize the pressing movement and can automatically return to its original state, which is beneficial to meeting the usage requirements. The locking block 34 engages with the locking groove 33 to fix the decorative member 325 and the main cover 2 together. To further explain, the mounting base 321 is provided with a through hole, and both the mounting base 321 and the upper surface of the button 323 are provided with one-way exhaust seals 326. This facilitates one-way airflow. The one-way exhaust seal 326 is preferably a one-way exhaust valve. To improve sealing performance, the button 323 is provided with a seal 327, preferably a sealing ring. Further, the lower surface of the mounting base 321 is provided with a sealing head 328, which has a vent hole. Ear holes are evenly spaced on the upper surface of the mounting base 321, centered around the through hole. The one-way exhaust seal 326 on the mounting base 321 can also cover the ear holes when closed. Finally, it should be noted that the reset member 322 uses a spring to facilitate the automatic return of the pressed button 32.

[0040] Example 4: Based on Example 1, Example 2, or Example 3, the lower cover 1 has a central hole 11, and airflow slits 12 are evenly spaced on the sidewall of the central hole 11, which facilitates exhaust. The inner sidewall of the lower cover 1 has a snap-fit ​​notch 13, while the outer sidewall of the main cover 2 has snap-fit ​​protrusions. The snap-fit ​​notch 13 and the snap-fit ​​protrusions engage to fix the lower cover 1 and the main cover 2 together. In this example, the snap-fit ​​notches 13 are evenly distributed on the inner sidewall of the lower cover 1, and the snap-fit ​​protrusions are evenly distributed on the outer sidewall of the main cover 2, which improves the stability of the connection. A sealing ring 21 is provided on the lower end face of the main cover 2, which improves the sealing performance during use.

[0041] Example 5: Based on Example 1, Example 2, Example 3, or Example 4, the release valve 4 includes a device hole 41 on the main cover 2. An exhaust valve stem 42 is installed in the device hole 41. A return element 43 is installed on the exhaust valve stem 42 at the device hole 41. A sealing gasket 44 is provided on the exhaust valve stem 42 below the device hole 41. This arrangement facilitates exhaust and pressure relief. Further, the return element 43 is a spring, which is convenient to implement.

[0042] The sealing ring 21 of this utility model is installed on the lower cover 1, and then the lower cover 1 is fastened to the main cover 2 to form a whole. The airflow gap on the lower cover 1 allows for smooth airflow between the lower cover 1 and the main cover 2. A one-way exhaust seal 326 is installed on the button 323, and then the pressing shell 324 is fastened to the button 323. A seal 327 is provided on the button 323 to make it a whole. The reset member 322 is installed between the main cover 2 and the button 323. The button 323 moves in the airtight chamber of the main cover 2 through the cooperation of the slot 33 and the block 34, without detaching from the main cover 2.

[0043] Example 6: Based on Example 1, Example 2, Example 3, Example 4, or Example 5, this utility model also provides a food preservation container, including a container body 10, with an open end cap 20 as described above. This utility model reduces the amount of air by extracting air from the inside of the container body 10, creating a relatively vacuum environment for storing the contents, reducing moisture content, and lowering the survival environment for bacteria, thus achieving a sealing and preservation effect.

[0044] When the button 323 is pressed, it compresses the reset member 322 as it moves downwards. This compresses the air in the recessed airtight chamber 35 of the main cover 2, and the one-way exhaust seal 326 on the main cover 2 seals the air inside the can 10. The can 10 opens on the button 323, releasing the air from the recessed airtight chamber 35 of the main cover 2, allowing air to circulate with the environment through the airflow gap of the button 323. When the button 323 is released, the reset member 322 moves the button 323 upwards, closing the one-way exhaust seal 326 on the button 323, preventing external air from entering the can 10. The one-way exhaust seal 326 on the main cover 2 then allows air to flow into the recessed airtight chamber 35 of the main cover 2. This process is repeated until the air pressure and the elasticity of the reset member 322 are balanced, making it impossible to extract air from the can 10. In this state, the air pressure inside the can 10 is lower than the external air pressure, achieving a sealing and preservation effect. This utility model allows the gas to pass through the release valve 42, which separates the release valve 4 from the main cover 2. This allows the gas pressure inside the container 10 to match the outside pressure, thereby opening the lid 20 of the food storage container.

[0045] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0046] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
