[0034] 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.

[0035] 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 storage cavity 101 with an opening at the front; 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.

[0036] 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. The seal 30 includes a positioning portion 34 and an elastic fin 31. The elastic fin 31 has a first side portion 311 and a second side portion 312 distributed along the radial direction of the opening. The first side portion 311 is connected to the positioning portion 34. When the panel 21 is closed, the elastic fin 31 abuts against the periphery of the opening and the second side portion 312 abuts against the panel 21 to form a sealing structure.

[0037] Specifically, the positioning portion 34 can position the elastic fin 31 on the panel 21, allowing the elastic fin 31 to extend toward the opening, thereby facilitating contact with the periphery of the opening when the panel 21 closes the opening. This provides support for the elastic fin 31, thereby improving the reliability of the seal when the opening is closed. The first side portion 311 of the elastic fin 31 can be connected to the positioning portion 34 to improve structural stability, and the second side portion 312 of the elastic fin 31 can contact the panel 21 to form a sealing structure. In other words, when the panel 21 closes the opening, the rear side of the elastic fin 31 can contact the periphery of the opening to form a seal, and the front side of the elastic fin 31 can also contact the panel 21 to form a seal, thereby forming a double seal between the periphery of the opening and the panel 21, which is conducive to improving the sealing effect.

[0038] According to the fresh-keeping container 100 of the embodiment of the present invention, by providing a sealing member 30 that can abut against the opening periphery and the panel 21 at the same time, a double seal can be formed between the panel 21 and the opening periphery, which is conducive to improving the sealing effect.

[0039] Combine Figure 4In some examples of the present invention, the first side portion 311 is closer to the opening than the second side portion 312. Specifically, the elastic fin 31 can form a seal at the first side portion 311 and also form a seal at the second side portion 312 farther from the opening. Thus, the first side portion 311 and the second side portion 312 can form a seal from the inside out around the opening, thereby improving the sealing effect.

[0040] Combine Figure 4 In some examples of the present invention, the first side portion 311 connects to the edge of the positioning portion 34 near the opening, while the second side portion 312 extends beyond the edge of the positioning portion 34 away from the opening and faces the panel 21 in the front-to-back direction. In other words, the side of the elastic fin 31 near the opening connects to the positioning portion 34 to form a fixed end, while the side away from the opening forms a free end. The elastic fin 31 faces the opening in the front-to-back direction. This ensures the structural stability of the elastic fin 31 while creating a deformation space between the elastic fin 31 and the positioning portion 34. This increases the space for movement of the elastic fin 31, making it easier for the seal 30 to conform to the perimeter of the opening and improving the sealing effect. Furthermore, the second side portion 312 can abut the panel 21 when the panel 21 is near the perimeter of the opening, further improving the sealing effect.

[0041] Combine Figure 4 In some examples of the present invention, the elastic fin 31 includes a first fin portion 313 and a rib portion 314. The first fin portion 313 is connected to the positioning portion 34, and the rib portion 314 is connected to the first fin portion 313 and extends forward. The rib portion 314 is provided on the second side portion 312 and abuts and cooperates with the panel 21 when the panel 21 is closed. Specifically, when the panel 21 closes the opening, the rib portion 314 can abut the rear surface of the panel 21. As a result, the rib portion 314 can support the first fin portion 313, and the first fin portion 313 can abut the periphery of the opening, and the rib portion 314 can abut the panel 21, thereby achieving a double seal between the panel 21 and the periphery of the opening, which helps to improve the structural stability of the sealing member 30.

[0042] Combine Figure 4 In some examples of the present invention, the end of the rib portion 314 facing away from the first fin portion 313 is configured as a curved surface, which can improve the contact between the rib portion 314 and the panel 21. Specifically, when the panel 21 closes the opening, the first fin portion 313 first contacts the periphery of the opening. As the closing pressure increases, the first fin portion 313 may deform, and this deformation force is transmitted to the rib portion 314. The curved surface of the rib portion 314 ensures that the rib portion 314 conforms to the panel 21 regardless of the direction of force transmitted to the rib portion 314, thereby improving the sealing effect. In addition, the curved surface can absorb shock and vibration, has good compression resistance and durability, and helps improve structural stability.

[0043] Combine Figure 4 In some examples of the present invention, when the panel 21 is closed, the retaining edge portion 314 is compressed and deformed forward by the periphery of the opening, which can improve the tightness of the connection between the retaining edge portion 314 and the panel 21 and improve the sealing effect.

[0044] In some examples of the present invention, when the panel 21 is opened, the second side portion 312 may abut against the panel 21 or the second side portion 312 may abut against the panel 21 with a gap, but the present invention is not limited thereto. Alternatively, when the panel 21 is opened, the second side portion 312 is fixedly connected to the panel 21.

[0045] Combine Figure 4 In some examples of the present invention, the elastic fin 31 has an arc-shaped protrusion in the radial middle area toward the rear along the opening. When the panel 21 is closed, the middle area of ​​the elastic fin 31 is compressed and deformed forward by the periphery of the opening. Specifically, the arc-shaped protrusion can enhance the structural strength and toughness of the elastic fin 31. When the elastic fin 31 contacts the barrel body 10, the top of the arc-shaped protrusion first contacts the periphery of the opening. As pressure is applied, the middle area of ​​the elastic fin 31 is compressed and deformed, thereby increasing the contact area between the elastic fin 31 and the periphery of the opening, which can further improve the sealing effect. In addition, the arc-shaped protrusion structure can also absorb shock and vibration, has good compression resistance and durability, and is conducive to improving structural stability.

[0046] In some examples of the present invention, when the panel 21 is closed, a gap is formed between the middle area of ​​the elastic fin 31 and the positioning portion 34 and / or the panel 21 along the front-to-back direction, thereby maintaining the elastic fin 31 .

[0047] 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.

[0048] In some examples of the present invention, 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.

[0049] 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 .

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] A fresh-keeping container 100 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0059] Among related technologies, refrigerator vacuum preservation technology creates a vacuum-sealed environment to isolate food from the outside air, achieving the effects of anti-bacteria, moisture-proof and anti-oxidation; the core is to use high pressure to extract the air in the container and food, so that the food is in a vacuum state, thereby effectively inhibiting the reproduction of aerobic bacteria and delaying the oxidation process of food.

[0060] To this end, the present invention proposes a fresh-keeping container 100 with a sealing structure, Figures 1 to 5 The fresh-keeping container 100 is provided with a sealing member 30 , which can form a double seal between the panel 21 and the periphery of the opening, thereby improving the sealing effect.

[0061] Specifically, the fresh-keeping container 100 is composed of a barrel body 10 and a drawer 22 assembly 20. The barrel body 10 is an integrated barrel structure or a barrel-shaped structure with an open side composed of two upper and lower parts that are glued or ultrasonically welded; the drawer assembly 20 includes a drawer 22 and a panel 21, and the panel 21 is connected to one end of the drawer 22.

[0062] The drawer assembly 20 is installed with a flexible or elastic seal 30 at a position facing the barrel body 10. The seal 30 is generally made of silicone, S-PVC or other soft materials that meet food grade safety standards. The seal 30 is arranged between the opening surface of the barrel body 10 and the drawer 22 assembly 20 to seal the fresh-keeping container 100.

[0063] More specifically, the seal 30 is installed between the barrel body 10 and the drawer assembly 20; the seal 30 is provided with an elastic fin 31, which contacts the barrel body 10. The elastic fin 31 includes a first fin portion 313 and a rib portion 314. The rib portion 314 blocks the space between the barrel body 10 and the drawer assembly 20. When the distance between the barrel body 10 and the drawer assembly 20 is reduced when the barrel body 10 and the drawer assembly 20 are evacuated, the rib portion 314 contacts the drawer assembly 20. During use, the first fin portion 313 abuts against the opening periphery or the front of the barrel body 10 to form a first sealing structure, and the rib portion 314 abuts against the panel 21 to form a second sealing structure, which helps to improve the sealing performance.

[0064] Furthermore, the seal 30 includes a second fin portion 32, which is disposed on the positioning portion 34 and is located away from the first fin portion 313. The second fin portion 32 is disposed between the panel 21 and the positioning portion 34 to provide support and cushioning for the positioning portion 34. The second fin portion 32 is connected to the positioning portion 34 and extends forward. The second fin portion 32 and the positioning portion 34 may also form an angle, and the angle between the second fin portion 32 and the positioning portion 34 decreases as the panel 21 is closed.

[0065] The present invention also provides a low-temperature fresh-keeping device, which includes a body, a refrigeration device and the fresh-keeping container 100 in the above embodiment.

[0066] The machine body is provided with a refrigeration compartment, a refrigeration device is provided in the machine body for cooling the refrigeration compartment, and the fresh-keeping container 100 is provided in the refrigeration compartment. By applying the aforementioned fresh-keeping container 100, the user's safety can be improved and the user's hand injury can be avoided.

[0067] Specifically, the fresh-keeping container 100 is placed in a refrigeration room and cooled by a refrigeration device in the refrigeration room, so that the fresh-keeping container 100 is in a low-temperature environment. In a low-temperature environment, biological activities such as bacteria are reduced, thereby achieving a low-temperature preservation function.
