Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to an adjustable breathable membrane structure for anti-pollution packaging of edible fungi. Background Technology

[0002] In the storage and transportation of edible fungi, the performance of the packaging plays a crucial role in their preservation quality. Because edible fungi are living organisms, fluctuations in ambient temperature during the distribution process after packaging directly affect the microenvironment inside the packaging. When the temperature rises, the respiration of the fungi increases, leading to a sharp increase in humidity and a rapid decrease in oxygen content inside the packaging. This high-humidity, low-oxygen environment easily causes mold and rot, severely shortening their shelf life. Conversely, when the temperature drops, excessive air permeability in the packaging can cause excessive moisture loss, leading to dehydration and drying of the fungi, affecting their quality and commercial value.

[0003] Currently, most common breathable packaging structures for edible fungi on the market use breathable membranes with fixed pore sizes or simple pore designs. These structures have significant limitations; their air permeability cannot adaptively adjust to changes in ambient temperature. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable breathable membrane structure for edible fungi packaging that prevents contamination. By using a pull member and an adjustable breathable component, the breathability inside the packaging can be regulated when the temperature is high, thereby reducing problems such as excessive humidity and insufficient oxygen inside the packaging caused by temperature rise, and increasing the freshness of edible fungi.

[0005] When the temperature drops, reduce the amount of air permeability to maintain a suitable microenvironment inside the packaging, thus ensuring the packaging effect and preservation quality of the edible fungi.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An adjustable breathable membrane structure for edible fungi packaging is provided, comprising a packaging film body, wherein multiple grooves are formed on the packaging film body, and an adjustable breathable component is fixedly connected to each of the multiple grooves, and a pulling component is fixedly connected to one end of each adjustable breathable component.

[0008] Furthermore, the adjustable ventilated component includes multiple plastic plates, which are fixedly connected to the interior of multiple grooves. Multiple ventilated holes are provided on the plastic plates. A rectangular plate is slidably connected to the outer side of the plastic plates. Multiple ventilated holes are provided on the rectangular plate. Each of the multiple ventilated holes is fixedly connected to a filter screen.

[0009] Furthermore, the pulling assembly includes two fixed blocks, which are fixedly connected to the upper side. One of the fixed blocks has a temperature-sensitive deformation sheet fixedly connected to one end, and the other end of the temperature-sensitive deformation sheet is fixedly connected to the other end of the rectangular plate.

[0010] Furthermore, each of the plastic plates is provided with a groove, and a slider is slidably connected in the groove. One end of the slider is fixedly connected to one end of the rectangular plate.

[0011] Furthermore, two elastic ropes are fixedly connected to one side of another fixed block, and the other ends of the two elastic ropes are fixedly connected to one end of the rectangular plate.

[0012] Furthermore, the temperature-sensitive deformation sheet is made of nickel-titanium alloy.

[0013] Furthermore, the outer side of the main body of the packaging film is coated with polytetrafluoroethylene.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses an adjustable breathable membrane structure for edible fungi packaging. Through the cooperation of a pull member and an adjustable breathable component, when the temperature is high, the breathability inside the packaging can be regulated, reducing problems such as excessive humidity and insufficient oxygen inside the packaging caused by temperature rise, and increasing the freshness of edible fungi.

[0016] When the temperature drops, reduce the amount of air permeability to maintain a suitable microenvironment inside the packaging, thus ensuring the packaging effect and preservation quality of the edible fungi. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-3 As shown, an adjustable breathable membrane structure for edible fungi packaging is described. The packaging film body 1 has multiple grooves 2 on it. Each groove 2 is fixedly connected to an adjustable breathable component. One end of each adjustable breathable component is fixedly connected to a pulling component. During use, after packaging is completed, when the temperature rises during transportation, the pulling component moves the adjustable breathable component, opening the breathable channel and increasing the breathability. This achieves breathability regulation inside the packaging, reducing problems such as excessive humidity and insufficient oxygen inside the packaging due to temperature rise, and increasing the freshness of edible fungi.

[0024] When the temperature drops, the pull component causes the adjustable ventilation component to slide in the opposite direction, closing the ventilation channel, reducing the amount of air permeable, and maintaining a suitable microenvironment inside the packaging to ensure the packaging effect and preservation quality of edible fungi.

[0025] like Figure 2 , Figure 3 As shown, the adjustable ventilation component includes multiple plastic plates 3, which are fixedly connected inside multiple grooves 2. Multiple ventilation holes 8 are provided on the plastic plates 3. A rectangular plate 10 is slidably connected to the outside of the plastic plates 3. Multiple ventilation holes 8 are provided on the rectangular plate 10. Each ventilation hole 8 is fixedly connected to a filter screen. In use, the rectangular plate 10 is slidably connected to the outside of the plastic plates 3 by pulling the puller, so that the ventilation holes 8 on the plastic plates 3 and the ventilation holes 8 on the rectangular plate 10 are superimposed, thereby adjusting the ventilation holes 8.

[0026] like Figure 2 As shown, the pulling assembly includes two fixed blocks 4, which are fixedly connected to the upper side of the groove 2. One of the fixed blocks 4 has a temperature-sensitive deformation plate 6 fixedly connected to one end, and the other end of the temperature-sensitive deformation plate 6 is fixedly connected to one end of the rectangular plate 10. When in use, the temperature-sensitive deformation plate 6 deforms when the temperature is high or low, thereby driving the rectangular plate 10 to move.

[0027] like Figure 3 As shown, multiple plastic plates 3 are provided with grooves 7, and sliders 11 are slidably connected in the grooves 7. One end of the slider 11 is fixedly connected to one end of the rectangular plate 10. In use, the rectangular plate 10 increases its stability during movement through the cooperation of the slider 11 and the grooves 7.

[0028] like Figure 2 , Figure 3As shown, two elastic ropes 9 are fixedly connected to one side of another fixing block 4. The other end of the two elastic ropes 9 is fixedly connected to one end of the rectangular plate 10. When in use, when the temperature-sensitive deformation plate 6 returns to its original shape and the tension disappears, the two elastic ropes 9 play a role, pulling the rectangular plate 10 to slide in the opposite direction, so that the air vents 8 on the rectangular plate 10 and the air vents 8 on the plastic plate 3 are gradually misaligned, reducing the amount of air permeability and maintaining a suitable microenvironment inside the packaging, so as to ensure the packaging effect and preservation quality of edible fungi.

[0029] like Figure 2 , Figure 3 As shown, the temperature-sensitive deformation plate 6 is made of nickel-titanium alloy. When in use, the nickel-titanium alloy can maintain its initial shape. When the temperature changes, it will change from one shape to another. When the temperature returns to the initial state, it can return to the original shape. This characteristic makes it very suitable for applications that require deformation according to temperature changes.

[0030] like Figure 1 As shown, the outer side of the packaging film body 1 is coated with polytetrafluoroethylene. When in use, the surface of polytetrafluoroethylene is extremely smooth, making it non-sticky and increasing the adhesion of dust, dirt and other substances to the outer side of the packaging film body 1, thus keeping the packaging film clean.

[0031] The working principle of this utility model is as follows: During use, in the storage and transportation process after packaging, when the ambient temperature rises, the temperature-sensitive deformation sheet 6 deforms due to the temperature rise, generating tension. This tension drives the rectangular plate 10 to slide on the outside of the plastic plate 3. The rectangular plate 10 slides in the groove 7 through the slider 11 to ensure the smoothness of the slide. At the same time, as the rectangular plate 10 slides, the vent holes 8 on the rectangular plate 10 gradually align with the vent holes 8 on the plastic plate 3, the ventilation channel opens, and the ventilation volume increases, thereby realizing the ventilation regulation inside the packaging, reducing problems such as excessive humidity and insufficient oxygen inside the packaging caused by temperature rise, and increasing the freshness of edible fungi.

[0032] When the temperature drops, the temperature-sensitive deformation sheet 6 returns to its original shape, and the tension disappears. At this time, the two elastic ropes 9 play a role, pulling the rectangular plate 10 to slide in the opposite direction, so that the air vents 8 on the rectangular plate 10 and the air vents 8 on the plastic plate 3 are gradually misaligned, reducing the amount of air permeability and maintaining a suitable microenvironment inside the packaging to ensure the packaging effect and preservation quality of edible fungi.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
