Description

Technical Field

[0001] This utility model relates to the field of fruit bagging technology, and in particular to a semi-transparent fruit bag. Background Technology

[0002] Fruit bagging, an important management technique in modern fruit tree cultivation, has been widely applied in the production of various fruits such as apples, pears, grapes, and citrus. This technique effectively blocks pests and diseases, reduces pesticide residues, prevents mechanical damage and sunburn, and improves fruit surface smoothness and appearance by wrapping the fruit in specially designed bags during its early development stages.

[0003] In pomegranate cultivation, pomegranate fruits exposed to strong sunlight are highly susceptible to sunscald due to high temperatures and intense ultraviolet radiation, leading to brown spots, cracks, and even rot on the peel, severely impacting their commercial value. To address this, research institutions have collaborated with growers to promote the use of specialized fruit bags for bagging cultivation. This physical shading significantly reduces the incidence of sunscald. However, most pomegranate fruit bags currently on the market are made of opaque or low-transmittance paper materials. While these effectively prevent sunscald, they present a significant technical challenge: the bags must be manually removed before the fruit matures to promote peel coloring. The red color of pomegranate fruit primarily comes from the accumulation of anthocyanins, whose synthesis is highly dependent on light induction. Bagged fruit kept in darkness for extended periods exhibits delayed peel color development; if the bags are not removed and the fruit not exposed to sunlight in time, the mature fruit will have a dull color and lack market appeal. Therefore, growers typically remove the bags 10-15 days before harvest to expose the fruit to sunlight for color change. However, the bagging process is highly manual, significantly increasing labor costs and management complexity. Utility Model Content

[0004] The purpose of this invention is to provide a semi-transparent fruit bag. Pomegranates are bagged through the semi-transparent bag, which can reduce the incidence of sunburn and allow for coloring without removing the bag later, thus significantly reducing production costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A semi-transparent fruit bag includes a bag body, the opening end of which is provided with a closing component, and the middle of the bag body is provided with an elastic ring. The bag body is made of white sulfuric acid paper, and the light transmittance of the bag body is 50-55%.

[0006] By adopting the above technical solutions, the semi-transparent bag body can reduce the incidence of sunburn, and coloring can be performed without removing the bag later, significantly reducing production costs. The elastic ring can expand the bag body during the bagging process, making it easier for workers to put on the bags.

[0007] A further feature of this invention is that the closure component consists of a flexible waterproof strip and a wire, the waterproof strip covering the wire, and the middle part of the waterproof strip being attached to the opening at the rear side of the bag body.

[0008] By adopting the above technical solution, the wire can fix the bag body and the fruit stem together and close the bag body, while the waterproof strip can protect the worker's hands and also protect the wire to prevent rusting.

[0009] A further feature of this invention is that the closure assembly includes an extension portion, an adhesive portion, and a protective layer. The extension portion is located on the rear side of the opening end of the bag body, the adhesive portion is located on the front side of the extension portion from left to right, and the protective layer is adhered to the adhesive portion.

[0010] By adopting the above technical solution, the extended part is bent forward and then glued to the front end of the bag body through the adhesive part, thereby closing the bag body.

[0011] A further feature of this invention is that a cut is provided in the middle of the extended portion.

[0012] By adopting the above technical solutions, the fruit stem can be bypassed more effectively.

[0013] A further feature of this invention is that a notch is provided on the front side of the opening end of the bag.

[0014] By adopting the above technical solutions, the fruit stem can be better adapted.

[0015] In summary, this utility model has the following beneficial effects: Firstly, the semi-transparent bag in this invention can reduce the rate of sunburn, and coloring can be done without removing the bag later, thus avoiding the later bag removal process and significantly reducing production costs.

[0016] Secondly, the elastic ring in this invention can expand the bag after the worker removes it, and keep the bag in an expanded state throughout the process, reducing contact between the bag and the fruit and preventing friction damage to the fruit.

[0017] Thirdly, the closure component in this utility model closes the bag body using wire and waterproof strip. The double-ended free wire can quickly close the bag body in the center, and the wire is protected by the waterproof strip, making it less prone to rusting.

[0018] Fourth, the closing component in this utility model can also close the bag by bending forward along the extension and pasting it. This method makes the bag more regular after it is fixed, which can reduce contact with the fruit. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1: A semi-transparent fruit bag, such as Figures 1 to 3As shown, the bag includes a bag body 1. The opening of the bag body 1 is equipped with a closing component 2, which consists of a flexible waterproof strip 21 and a wire 22. The waterproof strip 21 covers the wire 22, and the middle of the waterproof strip 21 is attached to the opening at the rear of the bag body 1. A notch 11 is provided on the front side of the opening of the bag body 1. The waterproof strip 21 protects the wire 22, while the wire 22 closes the opening of the bag body 1 from both sides, which is simple and effective.

[0026] An elastic ring 3 is located in the middle of the bag body 1. The elastic ring 3 uses its own elasticity to expand the bag body 1, making it convenient for workers to put the bag on. The bag body 1 is made of white tracing paper, and the light transmittance of the bag body 1 is 50-55%. The semi-transparent bag body 1 can reduce the incidence of sunburn, and can be colored later without removing the bag.

[0027] Example 2, as Figure 4 and Figure 5 As shown, the parts identical to those in Embodiment 1 will not be repeated here. The difference lies in that the closing component 2 includes an extension portion 23, an adhesive portion 24, and a protective layer 25. The extension portion 23 is located on the rear side of the open end of the bag body 1, and the adhesive portion 24 is located on the front side of the extension portion 23 from left to right. The protective layer 25 is adhered to the adhesive portion 24. A cutout 26 is provided in the middle of the extension portion 23. In use, the protective layer 25 is first peeled off, then the extension portion 23 is bent forward and then adhered to the front end of the bag body 1 to close the bag body 1. This closing method allows the bag body 1 to remain neat after being placed on the fruit.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
