Description

Technical Field

[0001] This utility model belongs to the field of food preservation bag technology, specifically relating to a food preservation bag for fruits and vegetables. Background Technology

[0002] In daily life, fruits and vegetables are an important part of people's diet, and their freshness and quality are directly related to people's health and quality of life. However, due to the physiological characteristics of fruits and vegetables and the influence of environmental factors such as respiration, microbial infection, and temperature fluctuations, fruits and vegetables are prone to spoilage and rot after harvesting, posing a significant challenge to people's food safety and nutritional intake. In recent years, with the development of packaging materials and technologies, vacuum packaging has been widely used in the field of fruit and vegetable preservation as an effective preservation method. Vacuum packaging removes the air inside the packaging to create a low-oxygen or even anaerobic environment, thereby inhibiting the growth of microorganisms and the respiration of fruits and vegetables, and extending the shelf life of fruits and vegetables. However, although vacuum packaging can greatly improve the preservation effect of fruits and vegetables, it cannot protect them. During transportation or storage, fruits and vegetables are easily damaged when subjected to external impacts and compression, affecting their quality and edibility. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a fruit and vegetable preservation bag that solves the problem of fruit and vegetable being easily damaged by impact or compression due to the inability to protect them.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fruit and vegetable preservation bag, comprising a preservation bag body, wherein the preservation bag body is composed of an inner preservation bag and a protective outer bag, the protective outer bag is disposed at the outer end of the inner preservation bag, and the upper inner wall of the protective outer bag is connected to the upper outer wall of the inner preservation bag, while the lower inner wall of the protective outer bag is connected to the lower outer wall of the inner preservation bag. The protective outer bag is an air bladder bag, used to isolate and buffer external impact force after inflation, thereby protecting the fruits and vegetables inside the inner preservation bag from the impact force. The protective outer bag is provided with an air nozzle for connecting an external air cylinder to inflate the inside of the protective outer bag with gas.

[0005] The beneficial effects of this utility model are as follows: after connecting to an external air cylinder through an air nozzle, gas can be injected into the protective outer bag. After the protective outer bag expands, it can effectively isolate and buffer external impacts and compressions, preventing fruits and vegetables from being damaged under impacts and compressions, thus affecting their quality and edibility.

[0006] To facilitate vacuum sealing of the inner bag:

[0007] As a further improvement to the above technical solution: the inner bag for preservation is provided with an exhaust pipe connected to its inner end, and a one-way valve is provided on the movable end of the exhaust pipe.

[0008] The beneficial effects of this improvement are as follows: one end of the exhaust pipe is connected to the inner bag of the fresh-keeping bag, and the other end is connected to the one-way valve. After the fruits and vegetables are placed inside the inner bag, the gas inside the inner bag can be extracted by using an external air cylinder connected to the one-way valve. This allows the fruits and vegetables to be in a vacuum state, which can reduce the rate of oxidation and spoilage, thereby maintaining their freshness and quality and extending their shelf life.

[0009] To facilitate the passage of the exhaust pipe:

[0010] As a further improvement to the above technical solution: a notch is provided at the top center of the protective outer bag, and the exhaust pipe is located on the inner bag within the notch.

[0011] The beneficial effect of this improvement is that the opening of the notch facilitates the passage of the exhaust pipe.

[0012] To facilitate opening and closing the inner bag:

[0013] As a further improvement to the above technical solution: a sealing strip is provided on the inner wall of the opening of the preservation bag for opening and closing the opening.

[0014] The beneficial effects of this improvement are as follows: by placing fruits and vegetables inside the inner bag and pinching the sealing strip to close the opening of the inner bag, the fruits and vegetables can be sealed and stored. Similarly, by operating in reverse, the opening of the inner bag can be opened, making it easy to take out the fruits and vegetables and facilitating reuse.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0021] like Figure 1-3As shown, a fruit and vegetable preservation bag includes a bag body 1, which is composed of an inner preservation bag 2 and a protective outer bag 3. The protective outer bag 3 is located outside the inner preservation bag 2, and its upper inner wall is connected to the upper outer wall of the inner preservation bag 2, while its lower inner wall is connected to the lower outer wall of the inner preservation bag 2. The protective outer bag 3 is an airbag used to isolate and buffer external impact after inflation, thereby protecting the fruits and vegetables inside the inner preservation bag 2 from impact. The protective outer bag 3 is equipped with an air nozzle 4 for connecting to an external air cylinder to inflate the protective outer bag 3. After connecting to the external air cylinder through the air nozzle 4, air can be injected into the protective outer bag 3, causing it to expand and effectively isolate and buffer external impacts and compression, preventing damage to the fruits and vegetables under impact and compression, thus affecting their quality and edibility. The inner preservation bag 2 is equipped with an exhaust pipe 7 connected to its inner end. Furthermore, a one-way valve 8 is provided on the movable end of the exhaust pipe 7. One end of the exhaust pipe 7 is connected to the inner preservation bag 2, and the other end is connected to the one-way valve 8. When fruits and vegetables are placed inside the inner preservation bag 2, the gas inside the inner preservation bag 2 can be extracted by connecting an external air cylinder to the one-way valve 8. This allows the fruits and vegetables to be in a vacuum state, which can reduce the rate of oxidation and spoilage, thereby maintaining their freshness and quality and extending their shelf life. A notch 5 is provided at the top center of the protective outer bag 3, and the exhaust pipe 7 is located on the inner preservation bag 2 within the notch 5. The notch 5 facilitates the passage of the exhaust pipe 7. A sealing strip 6 is provided on the inner wall of the opening of the inner preservation bag 2 for opening and closing. By placing fruits and vegetables inside the inner preservation bag 2 and pinching the sealing strip 6 to close the opening of the inner preservation bag 2, the fruits and vegetables can be sealed for storage. Similarly, the reverse operation can be used to open the opening of the inner preservation bag 2, making it easy to take out the fruits and vegetables and facilitating reuse.

[0022] The working principle of this utility model is as follows: After the fruits and vegetables are placed inside the inner bag 2, the opening of the inner bag 2 is closed by pinching the sealing strip 6, which can seal the fruits and vegetables for storage. At this time, simply hold the external air cylinder and connect it to the one-way valve 8 to draw the gas out of the inner bag 2. This allows the fruits and vegetables to be in a vacuum state, which can reduce the rate of oxidation and spoilage, thereby maintaining their freshness and quality and extending their shelf life. When the external air cylinder is connected to the air nozzle 4, gas can be injected into the outer protective bag 3. After the outer protective bag 3 expands, it can effectively isolate and buffer external impacts and compressions, preventing the fruits and vegetables from being damaged under impacts and compressions, thus affecting their quality and edibility.
