Technical Field
[0001] This utility model relates to the field of fruit and vegetable preservation technology, specifically a core pore membrane preservation bag. Background Technology
[0002] Food storage bags are common in daily life. To extend the shelf life of fruits and vegetables, they are often stored in these bags. However, fruits and vegetables are living organisms and continue to respire during storage to maintain normal life processes. The most important aspect of preserving fresh fruits and vegetables is controlling their respiration rate, inhibiting the intensity of respiratory metabolism, and thus extending their shelf life or improving preservation effectiveness. Currently, most food storage bags on the market are made of ordinary plastic materials. While they offer some preservation, they do not allow for gas exchange between the inside and outside of the bag. Furthermore, for fruits and vegetables with high respiration rates, excessive moisture generated by respiration or transpiration can accelerate spoilage, resulting in a shorter shelf life. Additionally, food storage bags offer poor protection; if accidentally dropped, the fresh fruits and vegetables inside are more likely to be damaged.
[0003] Based on this, a nuclear pore membrane food preservation bag is now provided, which can eliminate the drawbacks of existing technical solutions. Utility Model Content

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] Example 1
[0028] In this embodiment, as Figures 1-8 As shown, a core-pore membrane preservation bag includes an outer bag 1 and an inner bag 2 fixedly disposed inside the outer bag 1. The gap between the outer bag 1 and the inner bag 2 can be used to place ice, preservatives or other materials, which can be used for temperature regulation or to place small items, increasing the overall practicality and facilitating the preservation of fruits and vegetables. The top of the outer bag 1 is provided with a handle 3 for easy carrying by the user. Several ventilation zones 4 are evenly distributed on the surface of the outer bag 1. The ventilation zones 4 are all located at the connection between the outer bag 1 and the inner bag 2. The outer bag 1 and the inner bag 2 at the ventilation zones 4 are an integral structure to avoid affecting the normal use of the core-pore membrane assembly and to avoid affecting the ventilation effect. The ventilation zones 4 can be set as circular, square, triangular, etc. The shape and style of the core-pore membrane 12 are adapted to the shape and style of the ventilation zones 4. The number of ventilation zones 4 can be adjusted according to the maximum volume occupied by the preservation bag and the respiration intensity of the fruits and vegetables.
[0029] It also includes a sealing component and a core pore membrane component. The sealing component is located at the top of the outer bag 1 and the inner bag 2, and below the handle opening 3, to increase the overall sealing effect, so that the inside of the inner bag 2 forms a closed space, which can prevent items from falling out when the bag is being carried. The two-layer sealing structure can greatly reduce the probability of items falling out. The core pore membrane component is located inside the ventilation area 4 on the outer bag 1 to improve the ventilation effect. The core pore membrane component regulates the internal gas and temperature and humidity environment in the inner bag 2, thus extending the shelf life of fruits and vegetables.
[0030] Among them, such as Figure 4 As shown, the sealing assembly includes two sets of sealing elements. The structure of the two sets of sealing elements can effectively improve the overall sealing effect. The cross-sectional shapes of the two sets of sealing elements are consistent, which facilitates mass production without increasing production costs. One set of sealing elements is set on the top of the outer bag 1 to facilitate sealing the outer bag 1, and the other set of sealing elements is set on the top of the inner bag 2 to facilitate sealing the inner bag 2. The sealing elements include a first sealing strip 5 and a second sealing strip 6. The shapes and styles of the first sealing strip 5 and the second sealing strip 6 are compatible. The first sealing strip 5 and the second sealing strip 6 are interlocked to facilitate sealing the outer bag 1 and the inner bag 2.
[0031] Among them, such as Figures 2-7As shown, the core pore membrane assembly includes a groove 7 fixedly mounted on the outer bag 1. A first clip 8 is provided on the side of the groove 7 away from the inner bag 2. A protrusion 9 is fixedly mounted on one side of the first clip 8, and the protrusion 9 is engaged inside the groove 7. The shape and style of the groove 7 and the protrusion 9 are adapted to each other. The protrusion 9 can be concave-convex or annular, etc. The clip and the mother-daughter component are used to fix the position of the core pore membrane. The first clip 8 is connected to the outer bag 1 through the protrusion 9 and the groove 7, which facilitates the installation of the first clip 8 on the outer bag 1, facilitates replacement and cleaning operations, is convenient for multiple uses, and has good practicality. A vent 10 is opened on the surface of the first clip 8. A mother component 11 is fixedly mounted on the inner wall of the vent 10. A core pore membrane 12 is provided on the side of the mother component 11 near the inner bag 2. The core pore membrane 12 can prevent microorganisms from entering and multiplying inside the core pore membrane preservation bag. It has a moisture-permeable and waterproof effect, avoids condensation and liquid water entry, and has suitable air permeability, which can timely discharge harmful metabolites such as ethylene, thereby slowing down the decay of fruits and vegetables. The aging process facilitates the long-term storage and transportation of fresh fruits and vegetables. The parameters of the core pore membrane 12 can be adjusted according to the respiration intensity of the fruits and vegetables to meet the preservation needs of different types of fruits and vegetables. A daughter component 13 is provided on the other side of the core pore membrane 12. Both the mother component 11 and the daughter component 13 are in contact with the core pore membrane 12 but are not fixed, which facilitates the replacement of the core pore membrane 12. Through the cooperation of the daughter component 13 and the mother component 11, the core pore membrane 12 can be restricted, which facilitates the regulation of the respiration of fresh fruits and vegetables and improves the preservation effect. The sub-component 13 isolates the fresh fruits and vegetables inside the preservation bag from the core pore membrane 12, preventing impurities, dust, or liquid water on the fresh fruits and vegetables from clogging the micropore channels on the surface of the core pore membrane 12, and also strengthening the core pore membrane 12. A second clip 14 is fixedly installed on the outside of the sub-component 13. The outer diameter of the second clip 14 is adapted to the outer diameter of the mother component 11. The second clip 14 is set inside the outer bag 1 and the inner bag 2. The mother component 11 and the sub-component 13 are made of polyester material with stable biochemical properties.
[0032] Among them, such as Figure 8 As shown, the outer bag 1 consists of a protective layer 15, an outer membrane layer 16, and an insulation layer 17. The protective layer 15 is composed of several crisscrossing and spaced protective meshes. The protective mesh strips in the protective meshes all have a certain degree of elasticity, which provides support for the outer bag 1 and helps maintain the three-dimensional and aesthetically pleasing appearance of the outer bag 1. Several protective protrusions are evenly distributed on the surface of the protective meshes. The protective protrusions are made of elastic rubber material to increase the protective effect. The outer membrane layer 16 is made of ordinary plastic material and is used to seal the inner cavity of the outer bag 1 from the outside world, which provides a sealing effect. It has good chemical stability and is not harmful to the human body or fruits and vegetables.
[0033] Among them, such as Figure 3 and Figure 4 As shown, the inner bag 2 is made of antibacterial PE harmless material, such as polyester, polypropylene or polyvinylidene fluoride, which are harmless to fresh fruits and vegetables, so that the inner bag 2 can come into contact with fresh fruits and vegetables.
[0034] Among them, such as Figure 4 and Figure 6 As shown, the outer diameter of the first clip 8 is larger than the outer diameter of the groove 7, which makes it easy to remove the first clip 8 and replace the nuclear pore membrane 12.
[0035] Among them, such as Figure 4 and Figure 6 As shown, the size of the sub-component 13 is compatible with that of the nuclear pore membrane 12. The outer diameter of the nuclear pore membrane 12 is smaller than that of the parent component 11, thus limiting the size and enabling the nuclear pore membrane 12 to better perform its modified atmosphere function.
[0036] Example 2
[0037] The difference from Example 1 is that, as in Example 1, Figure 3 and Figure 4 As shown, the ventilation zones 4 located on the front and back sides of the outer bag 1 are positioned opposite each other to form a ventilation channel that communicates with the inner bag 2, thereby improving the breathability of the food storage bag.
[0038] When fruits and vegetables are stored inside the inner bag 2 of the core-pore membrane preservation bag, a certain amount of water vapor and harmful gases will be generated. The water vapor and harmful gases will enter the second clip 14 through the sub-component 13, and then be discharged to the outside of the outer bag 1 through the core-pore membrane 12. When outside air enters the inner bag 2 through the ventilation zone 4, the core-pore membrane 12 can effectively prevent dust, impurities and microorganisms in the air from entering. Through the above regulation, the physiological metabolism rate of fruits and vegetables is reduced, thereby delaying the life cycle. When fruits and vegetables need to be transported, the outer bag 1 and inner bag 2 are closed with the cooperation of the two sets of seals. The core-pore membrane preservation bag can then be moved to other locations through the handle 3. It is quite practical.
[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
