Description

A type of fruit and vegetable preservation film bag with a breathable structure Technical Field

[0001] This utility model relates to the field of food preservation film bags, specifically a fruit and vegetable preservation film bag with a breathable structure. Background Technology

[0002] In modern life, the preservation of fruits and vegetables is an important issue of concern. After being picked, fruits and vegetables are still living organisms and will continue to carry out physiological activities such as respiration. If the preservation measures are not appropriate, fruits and vegetables can easily lose moisture, and unsuitable oxygen and carbon dioxide concentrations can also lead to spoilage and rot, resulting in waste.

[0003] While traditional plastic wrap bags can prevent fruits and vegetables from being contaminated by the outside world and from losing too much moisture to a certain extent, the good sealing of the plastic wrap bags causes the oxygen content inside the bag to gradually decrease and the carbon dioxide content to continuously increase as the fruits and vegetables respire. This is very unfavorable for the long-term preservation of fruits and vegetables. In order to solve this problem, people began to develop fruit and vegetable plastic wrap bags with breathable structures. Summary of the Invention

[0004] The purpose of this invention is to provide a fruit and vegetable preservation film bag with a breathable structure to solve the problem mentioned in the background art that the preservation film bag has good sealing properties but is not easy to allow gas exchange.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vegetable and fruit preservation film bag with a breathable structure, comprising a bag surface, a folded surface fixedly provided on the side surface of the bag surface, a sealing opening fixedly provided on the outer surface of one end of the bag surface, and the sealing openings interlocking with each other, a screw threadedly provided on the outer surface of the folded surface, and a bottom ring fixedly installed on the outer surface of the screw, a slider sleeve threadedly installed on the outer surface of the screw, and a sliding barrel groove slidably installed on the outer surface of the slider sleeve, a contact blocking surface provided on the outer surface of the sliding barrel groove, an outer ring fixedly installed on the outer surface of the slider sleeve, and a rubber baffle embedded in the inner part of the outer ring, the rubber baffle, the slider sleeve and the contact blocking surface being concentrically designed, and the contact blocking surface being tapered.

[0006] Preferably, the end of the screw away from the bottom ring is tapered, and the bottom ring and the screw are concentric. A rotating cutting mechanism is provided between the bottom ring and the outer ring.

[0007] By adopting the above technical solution, the conical design of the screw can easily pierce the outer surface of the folded surface. The screw can then be tightened with the slider sleeve to fix the outer ring, outer cover, and bottom ring to the outer surface of the folded surface. This allows for easy replacement of the bag surface after it is damaged and cannot be sealed, reducing resource waste and plastic waste.

[0008] Preferably, the rotating cutting mechanism includes: a cutting blade, which is fixedly installed on the outer surface of the slider sleeve, and the outer surface of the slider sleeve is in contact with the outer surface of the bottom ring, and a micro-adhesive rubber gasket is provided between the bottom ring and the outer ring.

[0009] By adopting the above technical solution, the outer ring can rotate along with the cutting blade when it rotates, so that the cutting blade can cut the folded surface as it is tightened. At the same time, the micro-adhesive rubber gasket ensures the sealing after cutting. During cutting, the folded surface can be positioned and unfolded by the micro-adhesive rubber gasket and will not move randomly, thus preventing cutting failure. The folded surface can be automatically cut during the tightening process of the slider sleeve and screw.

[0010] Preferably, the outer surface of the bottom ring away from the screw is uniformly provided with block-shaped protrusions, and the block-shaped protrusions are arc-shaped.

[0011] By adopting the above technical solution, the block protrusion design allows the slider sleeve and screw to be tightened with leverage. At the same time, the arc design of the block protrusion prevents fruits and vegetables from sticking to the folded surface and blocking the ventilation gap of the bottom ring. This allows the slider sleeve and screw to be fixed more firmly and reduces the chance of the ventilation holes being blocked.

[0012] Preferably, the slider sleeve engages with the sliding barrel groove, and an outer cover is fixedly installed on the outer surface of the slider sleeve, with the side surface of the outer cover having a rough design.

[0013] By adopting the above technical solution, the engagement between the slider sleeve and the sliding barrel groove ensures that the outer cover will not rotate with the user when rotating it. At the same time, the rough design of the side surface of the outer cover reduces the chance of hand slippage when tightening.

[0014] Preferably, the folding surface is concave, and the outer surface of the folding surface is in contact with the outer surfaces of the bottom ring, the micro-adhesive rubber pad, and the outer ring, respectively. The bottom ring is located inside the folding surface, and the outer ring and the outer cover are located outside the folding surface.

[0015] By adopting the above technical solution, the concave design of the folding surface allows the plastic wrap bag to be folded when stored and to automatically deform when fruits and vegetables are placed inside, thus accommodating more fruits and vegetables. At the same time, the bottom ring, outer ring, and slider sleeve fixed on the outer surface of the folding surface can further reduce the chance of external objects blocking the ventilation holes.

[0016] Preferably, the outer surface of the outer ring is uniformly provided with positioning grooves, the sliding barrel groove and the outer cover are concentrically designed, and the outer surfaces on both sides of the outer cover are provided with elastic positioning buckles, which engage with the positioning grooves.

[0017] By adopting the above technical solution, the gap between the contact blocking surface and the rubber baffle can be controlled by the engagement of the elastic positioning buckle and the positioning groove, and the distance between the contact blocking surface and the rubber baffle can be fixed. It is convenient to determine the distance between the contact blocking surface and the rubber baffle by the engagement position of the elastic positioning buckle and the positioning groove, so that the size of the vent can be known and adjusted.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the fruit and vegetable preservation film bag with a breathable structure:

[0019] 1. After placing the fruits and vegetables into the plastic wrap bag and sealing the opening, the sliding barrel can be moved by pulling the outer cover. The sliding barrel can slide along the outer surface of the slider sleeve column with the contact block surface, so that the contact block surface can separate from the rubber baffle, thereby opening the gas flow channel and allowing the air inside and outside the plastic wrap bag to exchange freely. This effectively regulates the oxygen and carbon dioxide concentration inside the bag, creating a precisely suitable microenvironment for the fruits and vegetables, ensuring that they remain fresh during storage.

[0020] 2. When the outer and folded surfaces of the plastic wrap bag are damaged, preventing it from sealing, the bottom ring, outer ring, and outer cap must be removed. The bottom ring is then inserted into the folded surface of the new plastic wrap bag using a screw. The screw and slider sleeve are then tightened, allowing the cutting blade to rotate and approach the folded surface. Simultaneously, due to the adhesion of the micro-adhesive rubber gasket to the folded surface, it remains unfolded, allowing the cutting blade to neatly cut the folded surface. This allows the bottom ring, outer ring, and outer cap to be installed onto the new plastic wrap bag. By replacing the damaged plastic wrap bag, the amount of plastic waste caused by discarding the entire bag is significantly reduced, effectively lowering environmental pollution.

[0021] 3. The positioning buckle and positioning groove can control the position of the outer cover on the outer surface of the outer ring, allowing adjustment of the distance between the rubber baffle and the contact blocking surface. The conical design of the contact blocking surface and the distance between the rubber baffle can adjust the ventilation of the plastic wrap bag. Users can adjust the distance between the rubber baffle and the contact blocking surface according to the type of fruits and vegetables placed in the plastic wrap bag, dynamically adapting to the respiration rate and gas exchange needs of different types of fruits and vegetables. This ensures that the plastic wrap bag always maintains the optimal gas environment, thereby extending the shelf life of fruits and vegetables and ensuring the freshness and nutritional content of the stored fruits and vegetables.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6. This utility model provides a technical solution: a vegetable and fruit preservation film bag with a breathable structure, including a bag surface 1, a folded surface 2 fixedly provided on the side surface of the bag surface 1, a sealing opening 3 fixedly provided on the outer surface of one end of the bag surface 1, and the sealing openings 3 interlock with each other, a screw 6 is inserted on the outer surface of the folded surface 2, and a bottom ring 4 is fixedly installed on the outer surface of the screw 6, a slider sleeve 10 is threadedly installed on the outer surface of the screw 6, and a sliding barrel groove 12 is slidably installed on the outer surface of the slider sleeve 10, a contact blocking surface 14 is provided on the outer surface of the sliding barrel groove 12, an outer ring 7 is fixedly installed on the outer surface of the slider sleeve 10, and a rubber baffle 13 is embedded in the inner part of the outer ring 7. The rubber baffle 13, the slider sleeve 10 and the contact blocking surface 14 are concentrically designed, and the contact blocking surface 14 is tapered.

[0031] After placing the fruits and vegetables into the inner part of the bag 1, unfold the folded side 2, then seal the opening 3. Then pull the outer cover 11 to move the sliding barrel 12 together, so that the contact blocking surface 14 can separate from the rubber baffle 13, and a gap can be opened between the contact blocking surface 14 and the rubber baffle 13. The air inside and outside the plastic wrap bag can circulate with each other through the gap, so that the fruits and vegetables can be well preserved.

[0032] The end of the screw 6 away from the bottom ring 4 is tapered, and the bottom ring 4 and the screw 6 are concentric. A rotating cutting mechanism is provided between the bottom ring 4 and the outer ring 7.

[0033] When the bag surface 1 and the folded surface 2 are damaged and cannot be sealed, the bottom ring 4, the outer ring 7 and the outer cover 11 can be removed. The conical design of the screw 6 pierces the folded surface 2 of the new cling film bag, allowing the bottom ring 4 to pass through easily and be positioned on the folded surface 2.

[0034] The rotating cutting mechanism includes a cutting blade 9, which is fixedly installed on the outer surface of the slider sleeve 10, and the outer surface of the slider sleeve 10 is in contact with the outer surface of the bottom ring 4. A micro-adhesive rubber gasket 8 is provided between the bottom ring 4 and the outer ring 7.

[0035] Next, the outer ring 7 and the outer cover 11 are placed into the plastic wrap bag and tightened and fixed by the screw 6 and the slider sleeve 10. When tightening, the micro-adhesive rubber gasket 8 adheres to the outer surface of the folded surface 2, which will support the outer surface of the folded surface 2. At this time, as the slider sleeve 10 and the screw 6 are tightened, the cutting blade 9 will gradually approach the folded surface 2 and cut the outer surface of the folded surface 2. The folded surface 2 can be cut while tightening, so that the folded surface 2 can be broken open. At the same time, the bottom ring 4, the outer ring 7 and the outer cover 11 can be easily installed. By replacing the damaged plastic wrap bag, the plastic waste generated by discarding the whole bag is greatly reduced, and environmental pollution is effectively reduced.

[0036] The outer surface of the bottom ring 4 away from the screw 6 is uniformly provided with block-shaped protrusions 5, and the block-shaped protrusions 5 are arc-shaped.

[0037] The block-shaped protrusions 5 on the outer surface of the bottom ring 4 can effectively prevent the fruits and vegetables placed inside from clogging the ventilation holes, ensuring that the fruits and vegetables stored in the plastic wrap bag will not be unable to exchange air due to blockage. At the same time, when tightening the screw 6 and the slider sleeve 10, the block-shaped protrusions 5 can be used for leverage during installation, making the screw 6 and the slider sleeve 10 more secure after installation. This allows the outer ring 7 and the bottom ring 4 to squeeze the micro-adhesive rubber gasket 8 more tightly, reducing the amount of gas entering the plastic wrap bag from other places, allowing the fruits and vegetables to exchange air normally, and improving the convenience of installation.

[0038] The slider sleeve 10 engages with the sliding barrel groove 12, and an outer cover 11 is fixedly installed on the outer surface of the slider sleeve 10, and the side surface of the outer cover 11 is rough.

[0039] The rough, concave design on the surface of the outer cover 11 prevents slippage when the user grips and uses the outer cover 11. At the same time, the engagement between the slider sleeve 10 and the sliding barrel groove 12 prevents the outer cover 11 from rotating when the slider sleeve 10 is tightened with the screw 6.

[0040] The folding surface 2 is concave, and the outer surface of the folding surface 2 is in contact with the outer surfaces of the bottom ring 4, the micro-adhesive rubber gasket 8 and the outer ring 7 respectively. The bottom ring 4 is located on the inner side of the folding surface 2, and the outer ring 7 and the outer cover 11 are located on the outer side of the folding surface 2.

[0041] The concave design of the folded surface 2 allows the plastic wrap bag to hold more fruits and vegetables when in use, and can be folded up for storage to save space when not in use. At the same time, the bottom ring 4, the micro-adhesive rubber pad 8 and the outer ring 7 are set on the outer surface of the folded surface 2, which can effectively reduce the blockage of the outer cover 11 caused by external items covering it, and ensure that the ventilation and other functions are always unobstructed.

[0042] The outer surface of the outer ring 7 is uniformly provided with positioning grooves 16, the sliding barrel groove 12 and the outer cover 11 are concentrically designed, and the outer surfaces of both sides of the outer cover 11 are provided with elastic positioning buckles 15, and the elastic positioning buckles 15 engage with the positioning grooves 16.

[0043] By engaging the positioning groove 16 with the elastic positioning buckle 15, the position of the outer cover 11 on the outer ring 7 can be adjusted. The engagement position of the elastic positioning buckle 15 with the positioning groove 16 can also confirm the ventilation status. This allows the position between the contact blocking surface 14 and the rubber baffle 13 to be fixed and maintained, enabling the ventilation volume of the plastic wrap bag to be adjusted. Users can adjust the gap between the contact blocking surface 14 and the rubber baffle 13 according to the different types of fruits and vegetables placed inside the plastic wrap bag. This dynamically adapts to the unique breathing rate and gas exchange needs of different fruits and vegetables. Whether it is leafy vegetables with vigorous respiration or root vegetables with slow metabolism, the precise control of ventilation volume can ensure that the plastic wrap bag always maintains the most suitable gas environment, thereby maximizing the preservation period of fruits and vegetables and maintaining their freshness and nutritional components.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
