Description

Technical Field

[0001] This utility model relates to the technical field of food storage containers, and more particularly to a food storage container containing a core-pore membrane. Background Technology

[0002] Food storage containers are used to store food, extend its shelf life, and prevent it from spoiling; they are a common kitchen tool. Household food storage containers are often used to store various fruits and vegetables such as scallions, ginger, and garlic to maintain their freshness and flavor.

[0003] Nucleoporous membranes are microporous materials with excellent controlled atmosphere capabilities. By optimizing gas exchange, they can reduce moisture loss and mold growth, maintaining the freshness and nutritional value of food. Therefore, nucleoporous membranes are increasingly used in food preservation. For example, patent publication number CN221139428U discloses a device for transporting and preserving agricultural products. This device includes a storage box with a slot. An installation frame is fixedly installed on the inner wall of the slot, and a nucleoporous membrane is fixedly installed on the inner wall of the installation frame. Two baffles are fixedly installed on either side of the nucleoporous membrane. Each baffle has several first air inlets and several second air inlets, arranged in an alternating pattern. In use, agricultural products are placed inside the storage box. Outside air passes sequentially through the first and second air inlets of the baffles, then through the nucleoporous membrane, and finally through the first and second air inlets of the other baffle to enter the storage box, thus preserving the agricultural products inside.

[0004] When used in the home, food storage containers are usually placed in the kitchen, where splattered fruit and vegetable sap can easily adhere to the outer side of the nucleopore membrane. Furthermore, contaminants and rotten leaf juice may accumulate inside the container and adhere to the inner side of the membrane. This contamination on both sides of the membrane can potentially affect its modified atmosphere performance. Therefore, food storage containers using existing technology cannot guarantee the long-term stable operation of the modified atmosphere function of the nucleopore membrane, making them inconvenient for home use. Utility Model Content

[0005] To address the problem that existing modified atmosphere containers (MAPs) are difficult to maintain for long-term stable operation and are inconvenient for home use, this invention provides a food storage container with stable modified atmosphere function, easy maintenance, and suitable for home use.

[0006] The present invention provides a food storage box containing a nucleoporous membrane, which adopts the following technical solution:

[0007] A food storage container with a nucleopore membrane includes a container body, a lid for opening or closing the container body, and a food storage mechanism for modified atmosphere storage.

[0008] The preservation mechanism includes an inner window, an outer window detachably connected to the inner window, and a modified atmosphere assembly disposed between the inner window and the outer window. The inner window is used to prevent liquid inside the box from entering the modified atmosphere assembly, and the outer window is used to prevent liquid outside the box from entering the modified atmosphere assembly. The inner window and the outer window clamp and fix the modified atmosphere assembly. The modified atmosphere assembly includes a front dust cover, a rear dust cover detachably connected to the front dust cover, and a core pore membrane located between the front dust cover and the rear dust cover. The front dust cover and the rear dust cover clamp and fix the core pore membrane.

[0009] By adopting the above technical solution, when using the product, the ingredients are placed inside the container and the lid is driven to close the container. At this time, the inner window prevents liquid inside the container from contaminating the nucleopore membrane, the outer window prevents liquid outside the container from contaminating the nucleopore membrane, the front dust cover prevents small particles inside the container from adhering to the nucleopore membrane, and the rear dust cover prevents small particles outside the container from adhering to the nucleopore membrane. This comprehensively protects the nucleopore membrane, ensures the long-term stable operation of the modified atmosphere function of the nucleopore membrane, and ensures the freshness and quality of the preserved ingredients.

[0010] To clean the preservation mechanism, disassemble the inner and outer windows, then disassemble the front and rear dust covers. This allows you to separate the inner window, outer window, front dust cover, rear dust cover, and core pore membrane, and then clean all components. After cleaning, simply reassemble the inner window, outer window, front dust cover, rear dust cover, and core pore membrane.

[0011] The preservation mechanism effectively prevents liquids and particulate matter from affecting the nucleopore membrane, ensuring the long-term stable operation of the modified atmosphere packaging function and thus guaranteeing the freshness and quality of food. Furthermore, the disassembly and assembly process is simple and quick, and it is easy to clean and maintain, making it suitable for home environments. Users can easily perform cleaning and daily maintenance. The waterproof and dustproof design of the equipment greatly extends its service life, providing families with an efficient, convenient, and long-term stable preservation solution.

[0013] By employing the above technical solution, the outer arc surfaces of the long arc sections of several inner window flaps create a water-retaining side and a waterproof side for the inner window. When liquid splashes from the outside onto the water-retaining side, the outer arc surfaces of the long arc sections block or guide the liquid out of the inner window. When liquid splashes from the outside onto the waterproof side, the liquid is stored in a waterproof groove or guided out of the inner window, while air enters and exits through air channels. Through the water-retaining and waterproof sides, the two sides of the inner window can achieve ventilation and waterproofing in different ways.

[0014] Preferably, the outer window body includes an outer window frame, a wing plate integrally formed with the outer window frame, and an outer window flap fixed to the outer window frame; the wing plate surrounds the outer window frame, and the outer window flap is provided with several flaps, the structure of the outer window flap is consistent with the structure of the inner window flap.

[0015] By adopting the above technical solution, the outer window also has a water-blocking side and a waterproof side. In this embodiment, the waterproof side of the outer window faces the outside of the cover, which can prevent liquid outside the box from entering the modified atmosphere assembly.

[0016] Preferably, the inner window frame has a primary slot, and the outer window frame has a primary post, with the primary post and the primary slot being interference-fitted; and when the primary post extends into the primary slot, the inner and outer window frames clamp and fix the controlled atmosphere assembly.

[0017] By adopting the above technical solution, the outer window and the inner window can be connected by inserting the first-level pin into the first-level slot, and the climate control component can be clamped and fixed, achieving convenient and quick assembly and disassembly.

[0018] Preferably, the front dust cover includes a front frame and a first dustproof component disposed on the front frame, the first dustproof component covering the front frame; the rear dust cover includes a rear frame and a second dustproof component disposed on the rear frame, the second dustproof component being identical to the first dustproof component, the second dustproof component covering the rear frame.

[0019] By adopting the above technical solution, the front frame supports the first dustproof component and the rear frame supports the second dustproof component, thus avoiding the problems of loosening, deformation or falling off of the first and second dustproof components during use.

[0020] Preferably, the dustproof component is a PVC dustproof net.

[0021] By adopting the above technical solution, PVC dustproof netting has excellent dustproof performance, good air permeability and ventilation, and is easy to clean, making it suitable for food storage containers.

[0022] Preferably, the front frame has a secondary slot and the rear frame has a secondary post, the secondary post and the secondary slot are interference-fitted; and when the secondary post is inserted into the secondary slot, the front frame and the rear frame clamp and fix the nuclear pore membrane.

[0023] By adopting the above technical solution, the front dust cover and the rear dust cover can be connected by inserting the secondary insertion post into the secondary slot, and the nuclear pore membrane can be clamped and fixed at the same time, so as to achieve convenient and quick disassembly and assembly.

[0024] Preferably, a groove is provided on the inner window frame, and a sealing component is provided in the groove, with the front dust cover pressed against the sealing component.

[0025] By adopting the above technical solution, a reliable sealing effect is achieved using sealing components. These components can effectively prevent the exchange of air inside and outside the controlled atmosphere chamber, ensuring the stability of the controlled atmosphere environment.

[0026] Preferably, at least one preservation mechanism is provided; the preservation mechanism is provided on the lid, or the preservation mechanism is provided on the box, or the preservation mechanism is provided on both the lid and the box.

[0027] By adopting the above technical solution, the location of the preservation mechanism can be adjusted according to actual needs. When the preservation mechanism is placed on the lid, it helps to avoid excessive contact between the preservation mechanism and the food. When the preservation mechanism is placed on the box and the lid is damaged, only the lid needs to be replaced, without replacing the preservation mechanism or taking extra steps to disassemble and install the preservation mechanism onto a new lid. When the preservation mechanism is placed on both the lid and the box, it can provide more comprehensive modified atmosphere control, ensuring a more uniform gas distribution throughout the storage space.

[0028] Preferably, a sealing groove is provided on the inner side of the cover, and a sealing element is provided at the sealing groove; the cover is hinged with a buckle plate, and the buckle plate is engaged with the box body.

[0029] By adopting the above technical solution, when using the food, simply place the food into the box, put the lid on the box, and fasten the latch to make the latch engage with the box. Combined with the preservation mechanism, modified atmosphere preservation can be achieved. In addition, compared with ordinary food storage boxes, no additional steps are required for use.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The preservation mechanism effectively prevents liquids and particulate matter from affecting the nucleopore membrane, ensuring the long-term stable operation of the modified atmosphere function of the nucleopore membrane, thereby ensuring the freshness and quality of the food. Moreover, the disassembly and assembly process is simple and quick, easy to clean and maintain, suitable for home environments, and users can easily perform cleaning and daily maintenance.

[0032] The inner window has a water-blocking side and a waterproof side, allowing the two sides of the inner window to achieve ventilation and waterproofing in different ways. The same applies to the outer window. Therefore, both the inner and outer windows can be adjusted according to actual needs to adapt to different environmental conditions and functional requirements.

[0033] The location of the preservation mechanism can be adjusted according to actual needs. When the preservation mechanism is set on the lid, it helps to avoid excessive contact between the preservation mechanism and the food. When the preservation mechanism is set on the box and the lid is damaged, only the lid needs to be replaced, without replacing the preservation mechanism or taking extra steps to disassemble and install the preservation mechanism onto the new lid. When the preservation mechanism is set on both the lid and the box, it can provide more comprehensive modified atmosphere control, ensuring a more uniform gas distribution throughout the storage space.

[0045] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 9 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0046] A food storage container containing a nucleopore membrane, as shown in the reference. Figure 1 It includes a box body 1 with an open top, a lid 2 for opening or closing the top opening of the box body 1, and a preservation mechanism for modified atmosphere preservation.

[0047] Reference Figure 2 and Figure 3 The container body 1 is rectangular, and the lid 2 is rectangular. The lid 2 is distributed along the length of the container body 1, and the lid 2 fits and closes to the container body 1. A sealing groove is formed on the inner side of the lid 2, and a sealing element 14, which is a rubber sealing ring, is provided in the sealing groove. The sealing element 14 is embedded in the sealing groove to ensure a tight fit between the container body 1 and the lid 2, preventing the entry of external substances. A snap-on plate 15 is hinged to the long side of the lid 2. The snap-on plate 15 is engaged with the container body 1. The snap-on method of the snap-on plate 15 and the container body 1 is a common snap-on method in existing food storage containers, which will not be described in detail. There are two snap-on plates 15, which are mirror images of each other on the lid 2. The two snap-on plates 15 ensure that the lid 2 can firmly cover the container body 1 and maintain a seal. When in use, place the food into the box 1, cover the box 1 with the lid 2, and fasten the buckle 15 so that the buckle 15 is engaged with the box 1. Combined with the preservation mechanism, modified atmosphere preservation can be achieved.

[0048] In this embodiment, refer to Figure 2 and Figure 3The preservation mechanism is mounted on the lid 2, which helps to avoid excessive contact between the preservation mechanism and the food. A square mounting groove 16 is provided on the outer surface of the lid 2 for installing the preservation mechanism, and the groove is located near one of the shorter sides of the lid 2. A square vent hole 17 is provided at the bottom of the mounting groove 16, extending through the lid 2. When the lid 2 is closed onto the box 1, the mounting groove 16 is connected to the interior of the box 1 through the vent hole 17. Specifically, the preservation mechanism includes an inner window 3, an outer window 4, and a modified atmosphere assembly 5 disposed between the inner window 3 and the outer window 4. The modified atmosphere assembly 5 is clamped and fixed by the inner window 3 and the outer window 4.

[0049] Reference Figure 4 and Figure 5 The inner window 3 is used to prevent liquid inside the housing 1 from entering the modified atmosphere assembly 5. Further, the inner window 3 includes an inner window frame 31 and an inner window flap 32 fixed to the inner window frame 31. The inner window frame 31 is square-shaped and fits into the mounting groove 16. The inner window frame 31 is bolted to the mounting groove 16 of the cover 2, meaning the inner window 3 is detachably connected to the cover 2, and the inner window frame 31 is located at the bottom of the mounting groove 16.

[0050] Reference Figure 6 and Figure 7 The inner window flap 32 is elongated and distributed along the length of the cover 2. The cross-section of the inner window flap 32 resembles the Greek letter λ. The inner window flap 32 includes a long arc portion 321 and a short arc portion 322 integrally formed from the long arc portion 321. The outer arc surface of the long arc portion 321 serves to block liquid; that is, the outer arc surface of the long arc portion 321 is used to block liquid. A waterproof groove 6 is formed between the inner arc surface of the long arc portion 321 and the outer arc surface of the short arc portion 322.

[0051] Reference Figure 6 and Figure 7The inner window flaps 32 are provided with several flaps, which are arranged at equal intervals along the width direction of the cover 2. The arrangement of the inner window flaps 32 makes the short arc portion 322 of the inner window flaps 32 forked from the long arc portion 321 of the adjacent inner window flaps 32, and the two adjacent inner window flaps 32 do not contact each other, so that a gas channel 7 for gas circulation is formed between the two adjacent inner window flaps 32. The outer arc surface of the long arc portion 321 of the inner window flaps 32 forms a water-blocking side 33 for the inner window body 3. When liquid splashes from the outside to the water-blocking side 33, the outer arc surface of the long arc portion 321 blocks or guides the liquid out of the inner window body 3 (the effect is different depending on the placement of the inner window body 3, such as horizontal or vertical placement), and the gas enters and exits through the gas channel 7. The waterproof grooves 6 of several inner window flaps 32 form a waterproof side 34 for the inner window body 3, and the waterproof side 34 is away from the water-blocking side 33. When liquid splashes from the outside to the waterproof side 34, the liquid is stored in the waterproof grooves 6 or diverted out of the inner window body 3 (the effect varies depending on the placement of the inner window body 3), while gas enters and exits through the gas channel 7.

[0052] By using the water-blocking side 33 and the waterproof side 34, the two sides of the inner window 3 can achieve ventilation and waterproofing in different ways, and the orientation of the water-blocking side 33 and the waterproof side 34 can be adjusted according to actual needs. In this embodiment, referring to... Figure 6 and Figure 7 The inner window 3 is set on the cover 2. The cover 2 is mostly placed in a horizontal or slightly tilted direction. Based on the usage of the cover 2, in this embodiment, the water-blocking side 33 of the inner window 3 extends to the vent 17 and faces the inside of the box 1 to prevent the liquid inside the box 1 from affecting the performance of the modified atmosphere assembly 5, thereby ensuring the long-term modified atmosphere stability of the modified atmosphere assembly 5.

[0053] Reference Figure 4 and Figure 5 The outer window 4 is used to prevent external liquids from entering the modified atmosphere assembly 5. Further, the outer window 4 includes an outer window frame 41, a wing plate 42 integrally formed with the outer window frame 41, and outer window flaps 43 fixed to the outer window frame 41. The outer window frame 41 is square and adapts to the mounting groove 16, allowing the outer window frame 41 to extend into or out of the mounting groove 16. The wing plate 42 surrounds the outer window frame 41, and when the outer window frame 41 extends into and abuts against the inner window frame 31, the wing plate 42 abuts against the outer surface of the cover 2. The outer window flaps 43 are provided with several pieces, and the structure of the outer window flaps 43 is consistent with the structure of the inner window flaps 32, so that the outer window 4 also has a water-blocking side 33 and a waterproof side 34, and in this embodiment, the waterproof side 34 of the outer window 4 faces outwards from the cover 2.

[0054] In addition, refer to Figure 4 and Figure 5 The outer window 4 can be detachably connected to the inner window 3. (Combined) Figure 6The inner window frame 31 has a primary slot 8, which is circular and located near one corner of the inner window frame 31. The outer window frame 41 has a primary post 9, which is cylindrical and has an interference fit with the primary slot 8. By inserting the primary post 9 into the primary slot 8, the outer window 4 and the inner window 3 can be connected, and the climate control component 5 can be clamped and fixed. There are four primary slots 8, located near the four corners of the inner window frame 31, and there are four primary posts 9 corresponding to the four primary slots 8. The four primary posts 9 are interference-fitted into the four primary slots 8, making the connection between the inner window 3 and the outer window 4 more stable.

[0055] Reference Figure 5 and Figure 6 An air conditioning chamber 18 is provided on the side of the inner window frame 31 facing the outer window 4. The air conditioning chamber 18 is used to store the air conditioning assembly 5 and is square in shape. During cleaning, by prying open the wing plate 42, the outer window frame 41 is moved, and the first-level insert 9 is pulled out from the first-level slot 8. The air conditioning assembly 5 can then be removed for cleaning, and the outer window 4 and the inner window 3 connected to the cover 2 can be cleaned. During installation, by placing the air conditioning assembly 5 in the air conditioning chamber 18 of the inner window frame 31 and inserting the first-level insert 9 into the first-level slot 8, the outer window 4 and the inner window 3 can be connected. The air conditioning assembly 5 is clamped and fixed by the inner window 3 and the outer window 4, while protecting the air conditioning assembly 5 and preventing liquids or foreign objects inside or outside the box 1 from affecting it.

[0056] Specifically, refer to Figure 4 and Figure 5 The modified atmosphere assembly 5 includes a front dust cover 51, a rear dust cover 52, and a nuclear pore membrane 53 located between the front dust cover 51 and the rear dust cover 52. The front dust cover 51 is detachably connected to the rear dust cover 52, and the nuclear pore membrane is clamped and fixed by the front dust cover 51 and the rear dust cover 52.

[0057] Continue to refer to Figure 4 and Figure 5 The front dust cover 51 includes a front frame 511 and a dustproof component 512 disposed on the front frame 511. The shape of the front frame 511 is adapted to the modified atmosphere chamber 18, allowing the front frame 511 to extend into or out of the modified atmosphere chamber 18. The dustproof component 512 is a PVC dustproof mesh, a prior art technology widely used in computer cases. PVC dustproof mesh has excellent dustproof performance, good breathability and ventilation, and is easy to clean, making it suitable for food storage containers. The dustproof component 512 covers the front frame 511 and is fixedly connected to it. Thus, the dustproof component 512 prevents small particles (such as flour) inside the container 1 from adhering to the nucleopore membrane 53, preventing blockage of the channels on the nucleopore membrane 53, and ensuring the long-term stable operation of the modified atmosphere function of the nucleopore membrane 53.

[0058] Reference Figure 4 and Figure 5 The rear dust cover 52 includes a rear frame 521 and a second dustproof component 522 disposed on the rear frame 521. The rear frame 521 is also adapted to the shape of the modified atmosphere chamber 18, allowing the rear frame 521 to extend into or out of the modified atmosphere chamber 18. The second dustproof component 522 is identical to the first dustproof component 512, covering the rear frame 521 and being fixedly connected to it. Thus, the second dustproof component 522 prevents small particles (such as dust) from outside the housing 1 from adhering to the nuclear pore membrane 53, preventing blockage of the channels on the nuclear pore membrane 53, and ensuring the long-term stable operation of the modified atmosphere function of the nuclear pore membrane 53.

[0059] In use, the modified atmosphere function of the core pore membrane 53 achieves preservation. The water-blocking side 33 of the inner window 3 prevents liquid inside the box 1 from contaminating the core pore membrane 53, and the waterproof side 34 of the outer window 4 blocks liquid outside the box 1 from contaminating the core pore membrane 53. The dustproof component 1 512 prevents small particles inside the box 1 from adhering to the core pore membrane 53, and the dustproof component 2 522 prevents small particles outside the box 1 from adhering to the core pore membrane 53. This prevents blockage of the channels on both sides of the core pore membrane 53, thus comprehensively protecting the core pore membrane 53, ensuring the long-term stable operation of the modified atmosphere function of the core pore membrane 53, and ensuring the freshness and quality of the food.

[0060] Reference Figure 4 and Figure 5 The front dust cover 51 has a square-shaped groove for placing the nuclear pore membrane 53. The nuclear pore membrane 53 is fitted into the groove and is located within it. Additionally, a secondary slot 10, circular in shape, is provided on the front frame 511 near one corner of the front frame 511. A secondary post 11, cylindrical in shape, is provided on the rear frame 521. The secondary post 11 is press-fitted into the secondary slot 10, connecting the front dust cover 51 and the rear dust cover 52 and clamping the nuclear pore membrane 53 in place. Four secondary slots 10 are provided, each near one of the four corners of the front frame 511. The four secondary posts 11 are press-fitted into the four secondary slots 10, ensuring a more stable connection between the front dust cover 51 and the rear dust cover 52.

[0061] During cleaning, the front dust cover 51, rear dust cover 52, and nuclear pore membrane 53 can be separated and cleaned separately by pulling the secondary insert 11 out of the secondary slot 10. During installation, the front dust cover 51 and rear dust cover 52 can be connected by placing the nuclear pore membrane 53 in the groove and inserting the secondary insert 11 into the secondary slot 10, thereby clamping and fixing the nuclear pore membrane 53.

[0062] In addition, refer to Figure 5 and Figure 6 The inner window frame 31 also has a groove 12, which communicates with the modified atmosphere chamber 18. A sealing component 13, which is also a rubber sealing ring, is installed in the groove 12. When the modified atmosphere assembly 5 is placed in the modified atmosphere chamber 18, the front dust cover 51 presses against the sealing component 13, thereby forming a reliable sealing effect. At this time, the sealing component 13 can effectively prevent the exchange of air inside and outside the modified atmosphere chamber 18, ensuring the stability of the modified atmosphere environment.

[0063] The implementation principle of this application is as follows:

[0064] In use, place the ingredients into the container 1, cover the container 1 with the lid 2, and fasten the latch 15 so that the latch 15 is engaged with the container 1. The modified atmosphere packaging (MAP) function of the core membrane 53 then enables preservation. At this time, the water-blocking side 33 of the inner window 3 prevents liquid inside the container 1 from contaminating the core membrane 53, the waterproof side 34 of the outer window 4 prevents liquid outside the container 1 from contaminating the core membrane 53, the dustproof component 512 prevents small particles inside the container 1 from adhering to the core membrane 53, and the dustproof component 522 prevents small particles outside the container 1 from adhering to the core membrane 53. This comprehensively protects the core membrane 53, ensuring the long-term stable operation of the modified atmosphere packaging function and guaranteeing the freshness and quality of the preserved ingredients.

[0065] When cleaning the preservation mechanism, by prying open the wing plate 42, the first-level insert 9 can be pulled out from the first-level slot 8 to separate the inner window 3, outer window 4, and modified atmosphere assembly 5. Then, by pulling out the second-level insert 11 from the second-level slot 10, the front dust cover 51, rear dust cover 52, and core membrane 53 can be separated, and all parts can be cleaned.

[0066] After cleaning, the front dust cover 51 and the rear dust cover 52 can be connected by placing the nuclear pore membrane 53 in the groove and inserting the secondary post 11 into the secondary slot 10. The outer window 4 and the inner window 3 can be connected by placing the modified atmosphere assembly 5 in the modified atmosphere cavity 18 of the inner window frame 31 and inserting the primary post 9 into the primary slot 8. The modified atmosphere assembly 5 can be clamped and fixed by the inner window 3 and the outer window 4.

[0067] In summary, the preservation mechanism effectively prevents liquids and particulate matter from affecting the nucleopore membrane 53, ensuring the long-term stable operation of the modified atmosphere packaging function of the nucleopore membrane 53, thereby ensuring the freshness and quality of food. Furthermore, the disassembly and assembly process is simple and quick, and it is easy to clean and maintain, making it suitable for home environments. Users can easily perform cleaning and daily maintenance. The waterproof and dustproof design of the equipment greatly extends its service life, providing families with an efficient, convenient, and long-term stable preservation solution. Example

[0068] The difference between this embodiment and Embodiment 1 is that the positions of the mounting groove 16, the vent 17, and the preservation mechanism are different.

[0069] Reference Figure 8 In this embodiment, the mounting groove 16 is formed on the side wall of the box body 1, and the vent hole 17 is formed at the bottom of the mounting groove 16. The vent hole 17 extends through the box body 1 and connects the mounting groove 16 to the interior of the box body 1 through the vent hole 17. The preservation mechanism is provided at the mounting groove 16, that is, the preservation mechanism is provided on the box body 1.

[0070] Due to the potential wear and tear from frequent disassembly and installation of the cover 2, the preservation mechanism no longer relies on the cover 2. This avoids the wear and tear of the cover 2 indirectly affecting the preservation mechanism. In other words, when the cover 2 is damaged, only the cover 2 needs to be replaced; there is no need to replace the preservation mechanism or take additional steps to disassemble and install the preservation mechanism onto the new cover 2. This extends the service life of the cover 2 and also reduces wear and tear on it. Example

[0071] The difference between this embodiment and Embodiment 1 is that the number of preservation mechanisms is different.

[0072] Reference Figure 9 At least one preservation mechanism is provided. In this embodiment, two preservation mechanisms are provided, one of which is provided on the cover 2 and the other is provided on the box 1.

[0073] Two preservation mechanisms provide more comprehensive controlled atmosphere control, ensuring a more uniform gas distribution throughout the storage space.

[0074] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
