[0029] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Combine Figures 1 to 5 According to an embodiment of the present invention, the fresh-keeping container 100 comprises a barrel body 10, a panel 21, and a sealing member 30. The barrel body 10 has a front-opening storage cavity 101, which provides storage space for the fresh-keeping container 100. The panel 21 is configured to open and close the opening. In other words, the fresh-keeping container 100 has an openable and closable barrel body 10. Users can store food in the storage space of the barrel body 10 through the opening and then seal the storage space with the panel 21 to isolate the food from the outside world.

[0031] Furthermore, in order to improve the preservation effect, the fresh-keeping container 100 can also include a seal 30, which is arranged on the panel 21. When the user closes the opening, the panel 21 closes the front of the barrel body 10. Thus, the seal 30 can form a sealing structure in front of the barrel body 10 of the panel 21, thereby improving the sealing effect when the opening is closed.

[0032] Specifically, the sealing member 30 includes a positioning portion 34 and a first fin portion 31. The positioning portion 34 is connected to the panel 21. The first fin portion 31 is connected to the positioning portion 34 and extends backward. Thus, the positioning portion 34 can connect the first fin portion 31 to the panel 21 and can also provide support for the first fin portion 31. The first fin portion 31 extends in the direction of the opening. When the panel 21 is closed, the first fin portion 31 abuts against the periphery of the opening to form a sealing structure. When the panel 21 closes the opening, the panel 21 will gradually approach the opening. At this time, the rear end of the first fin portion 31 contacts the periphery of the opening. As the distance between the panel 21 and the periphery of the opening gradually decreases, the contact area between the first fin portion 31 and the periphery of the opening increases or the abutment between the first fin portion 31 and the periphery of the opening becomes tighter. When the panel 21 is fully closed, the first fin portion 31 can abut between the panel 21 and the periphery of the opening, thereby forming a stable sealing structure.

[0033] According to the fresh-keeping container 100 of the embodiment of the present invention, by providing the first fin portion 31 extending toward the opening, the tightness of the fit between the sealing member 31 and the periphery of the opening can be improved, thereby improving the sealing effect.

[0034] In actual application, the user can open and close the barrel body 10 by pushing and pulling the panel 21, so that the user can put in or take out food. After closing, an enclosed space is formed between the barrel body 10 and the panel 21, and the environment inside the fresh-keeping container 100 is more stable, which is conducive to improving the fresh-keeping effect.

[0035] In some examples of the present invention, when the panel 21 is open, the cross-section of the first fin portion 31 is configured as a cantilever, with one end connected to the positioning portion 34 and the other end spaced apart from the positioning portion 34. In other words, the first fin portion 31 has a fixed end connected to the positioning portion 34 and a free end extending rearward, which can improve the mobility or flexibility of the first fin portion 31. Thus, the first fin portion 31 can adapt to changes in the distance between the panel 21 and the perimeter of the opening. That is, the free end can be adaptively adjusted according to the pressure, thereby improving the sealing effect of the seal 30.

[0036] Combine Figure 4 In some examples of the present invention, the first fin portion 31 is arranged to be inclined in the direction away from the opening from the front to the rear, so that the first fin portion 31 is in contact with the outer peripheral edge of the opening. When the panel 21 is closed, the first fin portion 31 is compressed and deformed forward by the peripheral edge of the opening and reduces the angle between the first fin portion 31 and the positioning portion 34 (see Figure 4Specifically, the first fin portion 31 extends obliquely, and a deformation space can be constructed between the first fin portion 31 and the positioning portion 34. As the panel 21 is closed, the first fin portion 31 is subjected to pressure, and the first fin portion 31 can move toward the positioning portion 34, thereby reducing the angle between the first fin portion 31 and the positioning portion 34. The inclination angle of the first fin portion 31 becomes smaller. Therefore, as the panel 21 is closed, the opening periphery and the first fin portion 31 can change from point contact to surface contact, thereby improving the sealing tightness.

[0037] For example, when the distance between the panel 21 and the periphery of the opening is L1, the first fin portion 31 can abut against the periphery of the opening, and the angle between the first fin portion 31 and the positioning portion 34 is α1. When the distance between the panel 21 and the periphery of the opening is L2, the first fin portion 31 can also abut against the periphery of the opening, and the angle between the first fin portion 31 and the positioning portion 34 is α1, wherein L1 is greater than L2, and α1 is greater than α2.

[0038] More specifically, since the first fin portion 31 is gradually compressed during the closing process of the panel 21, the inclination angle of the first fin portion 31 gradually changes, which can effectively disperse the stress when subjected to force. Therefore, no large elastic force will be generated between the opening periphery or the front of the barrel body 10 and the panel 21, which is beneficial to improving the stability of the panel 21 after closing, and improving the stability and reliability of the seal 30 when sealing.

[0039] In some examples of the present invention, the first fin portion 31 includes a first side portion 311 and a second side portion 312. The first side portion 311 is connected to the positioning portion 34, and the second side portion 312 extends out of the positioning portion 34 in the projection along the front-to-back direction and is opposite to the panel 21 along the front-to-back direction. This can increase the matching area between the first fin portion 31 and the periphery of the opening, which is conducive to improving the matching effect.

[0040] More specifically, combined with Figure 4 The cross-sectional area of ​​the first side portion 311 is greater than the cross-sectional area of ​​the second side portion 312, or the cross-sectional area of ​​the first fin portion 31 gradually decreases in the direction from front to back, which can improve the structural stability of the connection between the first fin portion 31 and the positioning portion 34, and can also reduce the elastic force generated when the first fin portion 31 is sealed.

[0041] Combine Figure 4According to a specific embodiment of the present invention, the first fin portion 31 is connected to the positioning portion 34 at the lower part of the positioning portion 34. The cross-section of the first fin portion 31 and the positioning portion 34 is roughly "V"-shaped with the upper part open. The upper part or the second side portion 312 of the first fin portion 31 abuts against the periphery of the opening, that is, the upper opening of the "V" shape has mobility. When the panel 21 is closed or opened, the upper opening of the "V" shape can be reduced or expanded to adapt to the deformation of the first fin portion 31, and will not cause a large elastic force to be generated when the seal 30 is compressed, thereby ensuring the stability of the structure after the panel 21 is closed.

[0042] Combine Figure 4 In some examples of the present invention, the seal 30 further includes a second fin portion 32. The second fin portion 32 is connected to the positioning portion 34 and abuts against the panel 21 to form a sealing structure, thereby improving the tightness of the connection between the positioning portion 34 and the panel 21. In addition, the second fin portion 32 also acts as a buffer during sealing, further improving the sealing effect.

[0043] In some examples of the present invention, combined with Figure 4 The rear side of the panel 21 is provided with a positioning groove 301, and the positioning portion 34 is disposed in the positioning groove 301. The positioning groove 301 provides an assembly space for the positioning portion 34, facilitating rapid positioning and assembly of the seal 30. The second fin portion 32 is disposed on the front side of the positioning portion 34. The second fin portion 32 abuts against the inner bottom surface of the positioning groove 301, forming a support between the positioning portion 34 and the inner bottom surface of the positioning groove 301.

[0044] Optionally, the second fin portion 32 and the inner bottom surface of the positioning groove 301 can be clearance-fitted. When the positioning portion 34 is subjected to pressure, the second fin portion 32 can play a buffering and supporting role, thereby further increasing the sealing effect of the seal 30 .

[0045] Furthermore, the panel 21 may include a front plate and a rear plate, the front plate and the rear plate are connected along the front-to-back direction, and a positioning groove 301 is constructed on the rear plate.

[0046] In some examples of the present invention, the sealing member 30 is configured as an integrally formed silicone member, elastic plastic member or elastic resin member, which is easy to manufacture and assemble and has a certain deformation ability, thereby facilitating adaptation to the structure of the periphery of the opening and achieving a sealing effect.

[0047] In some examples of the present invention, the sealing member 30 is configured as a ring extending along the circumference of the opening and can be disposed around the opening to avoid generating gaps and improve the sealing effect.

[0048] In some examples of the present invention, the barrel body 10 is an integrated barrel body 10 structure, which can be easily manufactured and assembled.

[0049] In other examples of the present invention, the barrel body 10 includes an upper half and a lower half, and the upper half and the lower half are connected and bonded or welded.

[0050] Combine Figure 5 In some embodiments of the present invention, the fresh-keeping container 100 further includes a drawer 22. The drawer 22 is disposed in the storage cavity 101 and is connected to the panel 21. The drawer 22 is provided with a storage cavity 201. This configuration makes it convenient for users to take and put items. During use, the user can use the handle to drive the panel 21 to pull the drawer 22 out of the storage cavity 101. At this time, the items in the storage cavity 201 can be taken out along with the drawer 22, making it easier for the user to take them out. After the user places the items in the storage cavity 201, the user can use the handle to drive the panel 21 to push the drawer 22 into the storage cavity 101. At this time, the items in the storage cavity 201 can be brought in along with the drawer 22, improving the user's convenience.

[0051] In some embodiments of the present invention, the barrel body 10 is provided with an exhaust port for connecting to an exhaust device, and the exhaust port is connected to the storage cavity 101. The exhaust port can be connected to an external exhaust device. The exhaust device extracts the gas in the storage cavity 101 to form a low-pressure environment in the storage cavity 101. At this time, the bacteria and other organisms in the storage cavity 101 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 101; optionally, a vacuum environment can be created in the storage cavity 101 through the exhaust port to further improve the preservation effect of the fresh-keeping container 100.

[0052] In some embodiments of the present invention, the fresh-keeping container 100 also includes an exhaust component, which is connected to the storage cavity 101. The exhaust component can extract the gas in the storage cavity 101 to form a low-pressure environment in the storage cavity 101. At this time, the bacteria and other organisms in the storage cavity 101 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 101.

The seal 30 is arranged between the opening surface of the barrel body 10 and the drawer assembly 20 to seal the fresh-keeping container 100.

[0058] More specifically, the seal 30 is installed between the barrel body 10 and the drawer assembly 20; the seal 30 includes a first fin portion 31 and a positioning portion 34, the first fin portion 31 is connected to the positioning portion 34 and extends backward, the first fin portion 31 and the positioning portion 34 construct a V-shaped structure, the seal 30 is in contact with the barrel body 10, and when the distance between the barrel body 10 and the drawer assembly 20 becomes smaller, the angle between the first fin portion 31 and the positioning portion 34 decreases accordingly, so that no large elastic force is generated between the barrel body 10 and the drawer assembly 20.

[0059] Furthermore, the seal 30 includes a second fin portion 32, which is disposed on the side of the positioning portion 34 facing away from the first fin portion 31.
