Description

Double-layer fruit bag

The present invention relates to an agricultural product, in particular to a fruit bag for preventing fruit crops from being eaten by insects and birds.

Nowadays, when farmers grow fruit crops, they usually use fruit bags to cover the fruits. The fruit bags can isolate the fruits from the outside to prevent the fruits from being eaten by fruit insects, causing the fruits to rot and thus affecting the harvest. The existing fruit bags, such as TW The double-layer structure fruit bag of M570007U includes an outer bag and an inner bag. The outer bag includes an outer bag opening and an outer bag space that are connected to each other. The inner bag is arranged in the outer bag space. The inner bag includes an inner bag opening and an inner bag space that are connected to each other. The inner bag opening and the outer bag opening face the same side and are combined with the inner bag by heat pressing the two sides and the bottom. A drainage hole is left at one end of the bottom adjacent to the side to discharge moisture to prevent moisture from condensing into water droplets on the bag body and adhering to the fruit, so that the surface of the fruit is not easily rotten due to moisture.

However, the fruit bag of the prior art has not been heat-pressed at the opening of the outer bag and the opening of the inner bag, so fruit insects may still enter the fruit bag from the gaps. When the fruit bag is wrapped for a long time, part of the bag body is still closely attached to the surface of the fruit, so moisture or dew still adheres to the surface of the fruit and is not easy to discharge. In addition, because the bottom of the fruit bag is irregular after being sealed with a rope, the accumulated water may not necessarily flow to the position of the drainage hole. At this time, it is necessary to rely on manpower to tilt the fruit bag toward one end of the drainage hole to achieve the drainage effect. In this way, not only can the drainage effect not be achieved, but also the manpower burden is further increased to perform the drainage operation. Therefore, the overall structure of the fruit bag of the prior art has the above-mentioned problems and shortcomings, which really need to be improved.

In view of the shortcomings of the prior art, the present invention provides a fruit bag with a double-layer structure, in which the periphery of the inner bag is fixedly combined with the outer bag to form a closed joint, and a plurality of drainage ports are formed at the bottom of the inner bag to achieve the purpose of sealing and uniform drainage.

In order to achieve the above-mentioned invention purpose, the technical means adopted by the present invention is to design a fruit bag with a double-layer structure, which includes: an outer bag, which includes an outer opening and an outer space connected to each other; an inner bag, which includes an inner opening and an inner space connected to each other, the inner bag is contained in the outer bag and the inner opening is connected to the outer opening, the periphery of the inner bag is fixedly combined with the outer bag to form a closed joint, the closed joint is ring-shaped, and the bottom of the inner bag is formed with a plurality of drainage ports.

Furthermore, in the double-layered fruit bag, the outer bag is penetrated by a plurality of outer ventilation holes, and the inner bag is penetrated by a plurality of inner ventilation holes.

Furthermore, in the double-layered fruit bag, the outer bag is further formed with two outer cuts, which are relatively located near the outer opening of the outer bag and extend in a direction opposite to the outer opening.

Furthermore, in the fruit bag with a double-layer structure, each inner cut is relatively located near the inner opening of the inner bag and extends in a direction opposite to the inner opening, and the position of each inner cut corresponds to the position of each outer cut.

Furthermore, in the fruit bag with a double-layer structure, the drainage openings are arranged at equal intervals.

Furthermore, in the fruit bag with a double-layer structure, the inner bag is made of non-woven fabric.

Furthermore, in the double-layered fruit bag, the outer bag is made of a waterproof and light-transmitting material.

The advantage of the present invention is that, by wrapping the fruit with the present invention, when moisture in the air or dew forms water droplets around the fruit, in addition to the inner and outer air holes that help to discharge the moisture, the water droplets can be evenly discharged through the drainage ports to prevent the fruit from rotting due to moisture. Compared with the prior art, multiple drainage ports help the water droplets to be discharged from the drainage ports regardless of the direction they slide down, and there is no need to rely on manual tilting of the bag body to drain the water. In addition, when the water droplets do not slide down, they remain between the inner and outer bags, and the inner bag can also be cooled. Compared with the bag body of the prior art, the inner bag and the outer bag have a more complete heat-pressed bonding of the closed bonding part, and the coating is better, which can prevent fruit insects from entering the inner bag from the gap between the outer bag and the inner bag to bite the fruit.

Because the fruits covered by the present invention are fully protected, they only need to be sprayed with a small amount of pesticides before they bear fruit. When small fruits are formed, they are packed in fruit bags. After the small fruits are bagged, no pesticides are sprayed. During the growth period of the fruit, from medium fruit to large fruit to mature fruit, they are harvested, and no continuous spraying is required. Therefore, the residual concentration of pesticides after harvest is only about 0.01ppm, which can increase the domestic and foreign sales volume. The present invention can eliminate the worries of farmers. Taiwan's fruits do not need to worry about excessive pesticide residues and being returned to Taiwan when they are exported, which increases the income of farmers and the treasury, thereby improving the credibility and quality of Taiwan's fruits in the world.

The following is a combination of drawings and preferred embodiments of the present invention to further illustrate the technical means adopted by the present invention to achieve the intended purpose of the invention.

Please refer to FIG. 1 , which shows a double-layered fruit bag of the present invention, comprising an outer bag 10 and an inner bag 20 .

Please refer to Figures 1 to 3. The outer bag 10 includes an outer opening 11, an outer space 12, two outer cuts 13 and a plurality of outer ventilation holes 14. The outer opening 11 is connected to the outer space 12. In this embodiment, the outer bag 10 is formed by heat-pressing two opposite sides of two sheets to form an annular sheet as a whole. The material can be waterproof and light-transmissive polypropylene (PP). Each outer cut 13 is relatively located at the center of the outer bag 10 adjacent to the outer opening 11 and extends in a direction opposite to the outer opening 11. Each outer ventilation hole 14 passes through the surface of the outer bag 10, but is not limited to this. The outer cut 13 may not be formed. The material and form of the outer bag 10 can be changed according to user needs.

The inner bag 20 includes an inner opening 21, an inner space 22, two inner cuts 23, a plurality of drainage ports 24 and a plurality of inner vents 25, the inner opening 21 is connected to the inner space 22, each inner cut 23 is relatively located at the center of the inner bag 20 adjacent to the inner opening 21 and extends in a direction opposite to the inner opening 21, the position of each inner cut 23 corresponds to the position of each outer cut 13, and each drainage port 24 is equidistantly spaced through the inner bag 20. At the bottom of the inner bag 20, each inner vent hole 25 penetrates the surface of the inner bag 20. The inner bag 20 is placed in the outer bag 10, and the outer periphery of the inner bag 20 is heat-pressed and fixed to the inner surface of the outer bag 10 to form a closed joint 26. The closed joint 26 is ring-shaped. In this embodiment, the inner bag 20 is made of non-woven fabric, but it is not limited to this. The inner cut mark 23 may not be formed. The material and form of the inner bag 20 can be changed according to user needs.

When the present invention is used, please refer to Figures 2 to 4. The user opens the outer opening 11 and the inner opening 21 simultaneously, and passes a fruit 30 so that the fruit 30 is located in the inner space 22. The outer bag 10 and the inner bag 20 are opened at the positions of the inner cuts 23 and the outer cuts 13 in the middle to cover the fruit and branches, and then cross-fold and seal to achieve the sealing effect. The above-mentioned sealing method can improve the situation of fruit falling in traditional ring sealing. The above-mentioned inner cuts 23 and outer cuts 13 It helps the user to increase the sealing effect when sealing. Therefore, when moisture in the air or dew forms water droplets around the fruit 30, in addition to the inner air holes 25 and the outer air holes 14 helping to discharge the moisture, the water droplets can be evenly discharged through the drainage ports 24 to prevent the fruit 30 from rotting due to moisture. Compared with the existing technology, multiple drainage ports 24 help the water droplets to be discharged from the drainage ports 24 no matter which direction they slide down, without relying on manual tilting of the bag body for drainage.

In the above process, since the inner bag 20 and the outer bag 10 have a more complete heat-pressed bonding at the closed joint 26 compared to the bag body of the prior art, the covering property is better, which can prevent fruit insects from entering the gap between the outer bag 10 and the inner bag 20 to bite the fruit 30.

In the above process, the fruits 30 coated by the present invention are fully protected, and only a small amount of pesticides need to be sprayed before fruiting. When small fruits are formed, they are packed with fruit bags. After the small fruits are bagged, no pesticides are sprayed. During the growth period of the fruit, from medium fruit to large fruit to mature fruit, they are harvested, and no continuous spraying is required. Therefore, the residual concentration of pesticides after harvest is only about 0.01ppm, which can increase the domestic and foreign sales volume. The present invention can eliminate the worries of farmers. Taiwan's fruits do not need to worry about excessive pesticide residues and being returned to Taiwan when they are exported, which increases the income of farmers and the treasury, thereby improving the credibility and quality of Taiwan's fruits in the world.
