Description

Technical Field

[0001] This utility model relates to the technical field of food preservation, and in particular to a nuclear pore membrane food preservation component and food preservation bag. Background Technology

[0002] Nuclear pore membranes are nanoscale micropores formed by bombarding polymer films with high-energy particles. They are breathable but not water-permeable and can filter large particulate impurities. They can provide a suitable controlled atmosphere environment for fruits, vegetables and other agricultural products, slowing down their respiration and ripening process. As an efficient and environmentally friendly preservation solution, nuclear pore membranes are gradually gaining attention and being applied in the field of agricultural product transportation and storage.

[0003] Currently, a type of preservative using a nucleopore membrane is described in the market. For example, CN215571528U discloses a weld-free ventilation device for a preservative box, which includes a mother component and a daughter component. The daughter component and the mother component are interlocked. Both the mother component and the daughter component are provided with ventilation holes, and a nucleopore membrane is installed between the daughter component and the mother component. This ventilation device is installed on the box using a mounting fastener for a nucleopore membrane preservative device disclosed in CN216887807U. The mounting fastener includes interlocking clips A and B, which clamp the box from the inside and outside sides of the box, respectively. Clip A has a support part for placing the nucleopore membrane preservative device (CN215571528U). The nucleopore membrane preservative device is interference-fitted to the support part of clip A, thereby regulating the respiration of the agricultural products inside the box through the nucleopore membrane during the transportation of fresh agricultural products, thus achieving the function of preservation.

[0004] A box is a type of container, while a food storage bag is a common container used in households for storing food. Common types of food storage bags include flat bags, zipper bags, and stand-up pouches, which are suitable for storing vegetables, fruits, and other ingredients. Due to their portability, variety of sizes, and multifunctionality, food storage bags are frequently used in daily life.

[0005] However, since food storage bags are usually quite soft and can be bent in any direction, they are more prone to bending when used as containers to hold irregular items. The snap-fit ​​parts of clips A and B, the snap-fit ​​parts of the female and male parts, and the interference fit between clip A and the core pore membrane preservation device are all prone to falling off or separating. Therefore, the existing technology is not suitable for food storage bags. Utility Model Content

[0006] To address the issue that existing nuclear pore membrane preservation devices are unstable and unsuitable for food storage bags, this invention provides a nuclear pore membrane preservation component and food storage bag that is easy to install, highly stable, and suitable for different containers.

[0007] The first objective of this utility model is to provide a nuclear pore membrane preservation component, which adopts the following technical solution:

[0008] A nuclear pore membrane preservation component includes a female component and a female component that are threaded together. A nuclear pore membrane is disposed between the female component and the female component. The female component and the female component are connected by threads and clamped to the container wall to clamp and fix the nuclear pore membrane.

By passing the membrane seat through the through hole from the inside or outside of the container and making the first jacket abut against the container wall, the nuclear pore membrane is then laid flat in the membrane groove. The membrane cover is threadedly connected to the membrane seat to confine the nuclear pore membrane in the membrane groove. At the same time, the second jacket abuts against the first jacket, thereby clamping the daughter piece and the mother piece to the container wall, thus clamping the daughter piece and the mother piece to the container wall and fixing the nuclear pore membrane.

[0013] Preferably, the membrane seat is provided with reinforcing ribs.

[0014] By adopting the above technical solution, the reinforcing ribs help to strengthen the structural strength of the membrane seat and enhance its stability.

[0017] Preferably, the bottom of the cover cavity is provided with an elastic pressure block for pressing the nuclear pore membrane against the membrane groove. After the membrane cover is threadedly connected to the membrane seat, the elastic pressure block presses the nuclear pore membrane against the membrane groove.

[0018] By adopting the above technical solution, the elastic clamp can effectively absorb external impacts or pressure fluctuations, reduce the direct force on the membrane, and clamp and fix the nuclear pore membrane to prevent the nuclear pore membrane from folding, shaking or shifting.

[0019] Preferably, the first jacket has a rounded corner on the side opposite to the second jacket, and the second jacket has a rounded corner on the side opposite to the first jacket.

[0021] Preferably, a sealing groove is provided on the jacket, and a sealing element is provided in the sealing groove.

[0022] By adopting the above technical solution, the seal helps to fill the gap between jacket one, jacket two and the container wall, preventing liquid, gas or other substances from leaking from the container to the outside.

[0023] Preferably, the membrane seat and the jacket are integrally injection molded structures, and the membrane cover and the jacket are integrally injection molded structures.

[0024] By adopting the above technical solution, the firmness and integrity of the connection parts between the membrane seat and jacket one, and between the membrane cover and jacket two are ensured, the structural strength and stability are improved, and the number of parts and assembly steps are reduced.

[0025] Preferably, the membrane groove is provided with an insertion shaft, the insertion shaft and the membrane seat are on the same central axis, the nuclear pore membrane is provided with a through hole for the insertion shaft to pass through, the through hole and the insertion shaft are inserted into each other, the bottom of the cover cavity is provided with a slot body, the slot body and the cover cavity are on the same central axis, and the slot body and the insertion post are interference fit.

[0026] By adopting the above technical solution, during installation, the membrane cover is connected to the membrane seat by a threaded connection, and at the same time, the slot body and the insertion post gradually achieve an interference fit. The sub-component and the mother component are connected by a combination of threaded connection and interference fit, which ensures basic stability and disassembly, while reducing the risk of loosening under vibration or external force, making the connection tighter.

[0027] The second objective of this utility model provides a food preservation bag, which adopts the following technical solution:

[0028] A food preservation bag includes a bag body with heat preservation function and a nuclear pore membrane preservation component as described in any one of the above.

[0043] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 6 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.

[0044] Example 1

[0045] A nuclear pore membrane preservation component, as described above Figure 1 It includes a female component 1 and a female component 2 that are threaded together. A core pore membrane 3 is provided between the female component 1 and the female component 2. The female component 1 and the female component 2 are connected by threads and clamped to the container wall to clamp and fix the core pore membrane 3. The female component 1 and the female component 2 enable the core pore membrane 3 to communicate with the air inside and outside the container.

[0046] Specifically, refer to Figure 1 and Figure 2Sub-component 1 includes a membrane seat 11 and a jacket 12, which are integrally injection molded. The membrane seat 11 is cylindrical with one end closed (i.e., one end is closed, and the other is open). A membrane groove 4 is formed at the closed end of the membrane seat 11. The membrane groove 4 is circular and lies on the same central axis as the membrane seat 11, with a radius smaller than that of the membrane seat 11. The nuclear pore membrane 3 is also circular. The shape and size of the nuclear pore membrane 3 are compatible with the membrane groove 4, allowing the membrane 3 to be easily laid flat within the groove 4 and positioned by the groove 4. The jacket 12 is annular and is fitted onto the membrane seat 11, with the jacket 12 positioned near the open end.

[0047] Reference Figure 2 The inner wall of the membrane seat 11 is provided with reinforcing ribs 8, which are rectangular strips and distributed along the axial length of the membrane seat 11. There are multiple reinforcing ribs, which are evenly distributed along the circumferential direction of the membrane seat 11. The multiple reinforcing ribs 8 help to strengthen the structural strength of the membrane seat 11 and enhance its stability. In this embodiment, there are four reinforcing ribs 8, which are evenly distributed in a cross shape along the circumferential direction of the membrane seat 11.

[0048] Specifically, refer to Figure 1 and Figure 2 The mother component 2 includes a membrane cover 21 and a second jacket 22, which are also integrally injection molded structures. The membrane cover 21 is a regular polygonal cover. The regular polygonal design of the membrane cover 21 can increase the contact points for fingers or tools, enhance the user's grip and control during operation, and improve the convenience and comfort of opening the cover. In this embodiment, the membrane cover 21 is a regular 24-sided polygon.

[0049] Reference Figure 1 and Figure 2 The membrane cap 21 has a circular cap cavity 5. The inner wall of the cap cavity 5 has an internal thread 6, and the outer wall of the membrane seat 11 has an external thread 7. The external thread 7 and the internal thread 6 are threadedly engaged, that is, the female part 1 and the female part 2 are threadedly engaged. Thus, by driving the membrane cap 21 to be threadedly connected to the membrane seat 11, the membrane groove 4 and the cap cavity 5 can be overlapped and closed, confining the nuclear pore membrane 3 within the membrane groove 4.

[0050] Since nuclear pore membrane 3 is a light membrane, to prevent nuclear pore membrane 3 from folding, shaking, or shifting, refer to... Figure 1 and Figure 2The bottom of the cavity 5 of the cover body is provided with an elastic pressure block 9 for pressing the nuclear pore membrane 3 against the membrane groove 4. The elastic pressure block 9 is circular and can effectively absorb external impacts or pressure fluctuations, reducing the direct force on the membrane. The elastic pressure block 9 is made of rubber material, which has good flexibility and cushioning properties, and can prevent damage to the nuclear pore membrane 3. During installation, after the membrane cover 21 is threadedly connected to the membrane seat 11, the elastic pressure block 9 presses the nuclear pore membrane 3 against the membrane groove 4, thereby clamping and fixing the nuclear pore membrane 3.

[0051] Reference Figure 2 and Figure 3 The second jacket 22 is also annular, and its outer radius is the same as that of the first jacket 12. The second jacket 22 is fitted onto the membrane cap 21. When the membrane cap 21 is threadedly connected to the membrane seat 11, the second jacket 22 and the first jacket 12 abut against each other. In use, a through hole is provided on the container to connect the inside and outside of the container, and the shape and size of the through hole are adapted to the cross-section of the membrane seat 11. The membrane seat 11 is passed through the through hole from the inside or outside of the container, and the first jacket 12 abuts against the container wall. Then, the nucleopore membrane 3 is laid flat on the membrane groove 4. The membrane cap 21 is threadedly connected to the membrane seat 11, and the second jacket 22 and the first jacket 12 abut against each other, thereby clamping the daughter piece 1 and the mother piece 2 against the container wall.

[0052] Reference Figure 2 and Figure 3 The first sleeve 12 has a rounded corner part 10 on the side opposite to the second sleeve 22, and the second sleeve 22 has a rounded corner part 13 on the side opposite to the first sleeve 12. The rounded corner part 10 and the rounded corner part 13 help to reduce sharp parts and prevent damage to the container and the items inside and outside the container.

[0053] In addition, refer to Figure 3 A sealing groove 14 is provided on the first jacket 12, and a sealing element 15 is provided in the sealing groove 14. The sealing element 15 is a sealing ring. The sealing ring is a conventional technology in the prior art and will not be described in detail. The sealing element 15 helps to fill the gap between the first jacket 12, the second jacket 22 and the container wall, ensure the sealing of the connection, and prevent liquid, gas or other substances from leaking from the container to the outside.

[0054] Reference Figure 2 and Figure 3The bottom of the membrane tank 4 has multiple circular vent holes 23, which connect to the open end. The membrane cover 21 has multiple arc-shaped vent holes 24, which extend through the inner and outer sides of the cover 21, connecting the cover cavity 5 to the outside. When the sub-component 1 and the mother-component 2 are clamped to the container wall, the core-pore membrane 3 is positioned between the vent holes 23 and 24. These vent holes provide a channel for air circulation between the inside and outside of the container. In other words, the sub-component 1 and the mother-component 2 connect the core-pore membrane 3 to the inside and outside of the container, and the core-pore membrane 3, positioned between the vent holes 23 and 24, regulates the gas flow rate, thereby preserving the agricultural products inside the container. Combined with the sealing element 15, this ensures that gas passes through the core-pore membrane 3 into and out of the container.

[0055] The implementation principle of this embodiment is as follows: In use, a through hole is provided on the container to connect the inside and outside of the container, and the shape and size of the through hole are adapted to the cross-section of the membrane seat 11. The membrane seat 11 is passed through the through hole from the inside or outside of the container, and the first jacket 12 is abutted against the container wall. Then, the nuclear pore membrane 3 is laid flat on the membrane groove 4. The membrane cover 21 is threadedly connected to the membrane seat 11 to restrict the nuclear pore membrane 3 in the membrane groove 4. The nuclear pore membrane 3 is pressed against the membrane groove 4 by the elastic pressure block 9. At the same time, the second jacket 22 and the first jacket 12 are pressed against each other, so that the daughter part 1 and the mother part 2 are clamped against the container wall.

[0056] In summary, the sub-component 1 and the mother component 2 can simultaneously clamp onto the container wall and secure the nuclear pore membrane 3, allowing for easy installation and removal of the nuclear pore membrane. Simultaneously, the sub-component 1 and mother component 2 can be easily installed or removed from the container, simplifying the installation process and reducing the number of parts used. Furthermore, the threaded fit between the sub-component 1 and mother component 2 is more stable than a snap-fit ​​connection. Even if the container (such as a food storage bag) undergoes slight deformation, the sub-component and mother component can still maintain a tight fit. Suitable for various types of containers such as boxes and food storage bags, it can withstand bending from any direction within the food storage bag, thereby improving overall stability and reliability.

[0057] Example 2

[0058] The difference between this embodiment and Embodiment 1 is that an insert shaft 16 is also provided on the membrane groove 4, as shown in the figure. Figure 4 and Figure 5 The insertion shafts 16 are distributed along the axial direction of the membrane seat 11, and the insertion shafts 16 and the membrane seat 11 are on the same central axis. The nuclear pore membrane 3 has through holes 17 for the insertion shafts 16 to pass through, and the through holes 17 are inserted into the insertion shafts 16. During installation, by inserting the nuclear pore membrane 3 into the insertion shafts 16, the nuclear pore membrane 3 can be further restrained and prevented from falling off.

[0059] Reference Figure 4 and Figure 5The bottom of the cover cavity 5 is provided with a slot body 18, which is located on the same central axis as the cover cavity 5. The slot body 18 is interference-fitted with the insert post. During installation, the diaphragm cover 21 is threadedly connected to the diaphragm seat 11 by driving the diaphragm cover 21. At the same time, the slot body 18 and the insert post gradually achieve interference fit. The female part 1 and the female part 2 are connected by thread and interference fit to ensure basic stability and disassembly, while reducing the risk of loosening under vibration or external force, making the connection tighter.

[0060] Example 3

[0061] A type of food storage bag, as shown in the reference Figure 6 The bag includes a bag body 19 and a nuclear pore membrane preservation component, which is the same as the nuclear pore membrane preservation component in Embodiment 1 or Embodiment 2. The bag body 19 has a heat preservation function. In this embodiment, the bag body 19 is a bag body 19 with a heat preservation layer. The heat preservation function helps to maintain a suitable temperature inside the bag body 19 when storing or transporting agricultural products. An opening self-sealing component 20 is provided at the opening of the bag body 19. The opening self-sealing component 20 is used to open or seal the opening of the bag body 19. The opening self-sealing component 20 is a self-sealing clip in the prior art.

[0062] The bag body 19 has a through hole on its wall that connects the inside and outside of the bag body 19. The shape and size of the through hole are adapted to the cross-section of the membrane seat 11. The nucleus pore membrane preservation component is installed at the through hole.

[0063] The implementation principle of this embodiment is as follows: the opening of the bag body 19 is opened or sealed by the self-sealing component 20, thereby loading and sealing the agricultural products into the bag body 19. The bag body 19 itself provides a suitable temperature environment for preservation through its heat preservation function. The rate of gas flow is adjusted by the core pore membrane preservation component, thereby effectively preserving the agricultural products in the bag body 19.
