[0031] This utility model provides a technical solution: a multifunctional citrus-specific fruit bag, which includes a first bag body 1 and a second bag body 2 disposed inside the first bag body 1. A mesh bag 3 is provided on the inner side of the first bag body 1, and a ventilation hole 5 is provided on the first bag body 1. The bottom of the second bag body 2 has a breathable cotton layer 4, and a breathable micropore 6 is provided on the second bag body 2.
[0032] Specifically, this citrus-specific fruit bag features a double-bag design. The mesh bag 3 in the first bag 1 is used to hold insecticide packets. The choice of insecticide packet can be adjusted according to the specific season or pest, making insect control more targeted. Furthermore, using the mesh bag 3 facilitates easier replacement of the insecticide packet. Additionally, there should ideally be a certain distance between the mesh bag 3 and the second bag 2 to minimize contact between the insecticide packet and the second bag 2. The second bag 2 is used to hold the citrus fruits. It has ventilation micropores 6, while the first bag 1 has ventilation holes 5, ensuring the citrus fruits can breathe normally within the second bag 2. Furthermore, a breathable cotton layer 4 is also placed at the bottom of the second bag 4, which helps to balance the temperature and humidity differences inside and outside the second bag 2, creating a more stable and suitable growing environment for the citrus fruits. Therefore, this citrus-specific fruit bag improves breathability while providing good insect control.
[0033] As an optional implementation, in some embodiments, a first sealing strip 7 is provided at the opening of the first bag 1, and a second sealing strip 8 is provided at the opening of the second bag 2. The first sealing strip 7 and the second sealing strip 8 can provide a complete seal when the first bag 1 and the second bag 2 need to be sealed, effectively preventing external impurities from entering the bag and avoiding contamination of the citrus fruits.
[0034] In the above embodiment, the first bag body 1 is further provided with a through hole 9, which is located on the side of the first sealing strip 7 facing outward. When the first bag body 1 needs to be fixed, it can be fixed by passing a hook, hanging ring, or other hanging device through the through hole 9.
[0035] As an optional implementation, in some embodiments, the inner side of the first bag 1 and the outer side of the second bag 2 are respectively provided with matching hook and loop fasteners (not shown in the figure). Specifically, to prevent the second bag 2 from frequently moving within the first bag 1 due to inclement weather, thereby damaging the citrus fruits, hook-and-loop fasteners and loop fasteners are adhered at corresponding positions on the inner side of the first bag 1 and the outer side of the second bag 2. The combination of these two types of fasteners improves the stability of the second bag 2 within the first bag 1.
[0036] As an optional implementation, in some embodiments, the first bag 1 includes, from the inside out, a base layer 10, a waterproof layer 11, and a light-shielding layer 12. The waterproof layer 11 is coated on the base layer 10, and the light-shielding layer 12 is coated on the waterproof layer 11. The first bag 1 has a three-layer structure design. The base layer 10 provides the necessary structural strength for the first bag 1. The waterproof layer 11, in conjunction with the breathable micropores 6, maintains a dry environment inside the first bag 1 because the breathable micropores 6 are small enough to prevent water droplets from passing through, but large enough to allow air and water vapor exchange. The light-shielding layer 12 blocks direct sunlight, preventing citrus fruits from being sunburned, discolored, or experiencing quality degradation due to prolonged exposure to sunlight.
[0037] In the above embodiments, the base layer 10 is made of non-woven fabric, the waterproof layer 11 is made of polyurethane, and the light-shielding layer 12 is made of resin. Non-woven fabric has good breathability and is also an environmentally friendly material, making it suitable as the base layer of the first bag 1. Polyurethane has excellent waterproof performance, effectively blocking the penetration of external moisture such as rainwater and dew. Therefore, using polyurethane as the waterproof layer of the first bag 1 ensures that the inside of the first bag 1 remains dry. Resin has good light-shielding performance, effectively blocking direct sunlight from hitting the citrus fruits and preventing surface burns. However, it is not as strong as paper bags, which could reduce the photosynthetic efficiency of the citrus fruits, thus affecting their quality and color. Therefore, using resin as the light-shielding layer of the first bag 1 ensures that the citrus fruits receive adequate sunlight, thereby improving their quality and yield.
[0038] As an optional implementation, in some embodiments, the vent holes 5 correspond to the positions of the vent micropores 6. This facilitates faster airflow and enhances breathability.
[0039] In the above embodiment, furthermore, the ventilation holes 5 are opened at the bottom of the first bag body 1, and the ventilation micropores 6 are opened at the bottom of the second bag body 2. For citrus fruits, opening the ventilation micropores 6 at the bottom of the second bag body 2 and the ventilation holes 5 at the bottom of the first bag body 1 will further help the citrus fruits to breathe, thereby allowing them to grow better and thus keeping the citrus fruits fresh and having a better taste.
[0040] As an optional implementation, in some embodiments, the mesh bag 3 is positioned in the middle of the inner side of the first bag body 1. The position of the mesh bag 3 can be adjusted according to actual use, as long as there is sufficient space to place the insect repellent packet. The mesh bag 3 is chosen to be positioned in the middle of the inner side of the first bag body 1 because the second bag body 2 is also essentially located in the middle of the first bag body 1. This allows the insect repellent packet placed in the mesh bag 3 to better repel insects from the citrus fruits inside the second bag body 2, enhancing the insect-repellent effect.
