Description

Fruit envelope using synthetic resins

The present invention relates to an orchard bag, and in particular, the fruit bag is manufactured by using two layers of synthetic resin film and a paper bag mixed with an insect repellent, and then aeration and drainage are formed. The present invention relates to an orchard bag using synthetic resin, which further improves preservation, sweetness, and color of the fruit by improving long-term insect repellent efficiency, light emission and drainage.

In general, in the cultivation of fruit trees, enveloping the fruit tree is the most labor-intensive task. Enclosing the fruit tree in such a way can prevent damages such as yunmun disease, aptitude, and black star disease, and cuticle layer on the skin surface. It protects against rust and prevents rust, softens and thins the skin, and clears the color of the fruit to make the appearance of the fruit beautiful and clean.

However, conventional paper bags such as newspapers and oily papers are easily torn by weathering and may cause rust, pests, and skin stains. Especially, algae, such as magpies, can easily peck and protect the envelopes. Insect repellent is applied, but the effect lasts for about 1 month.

In addition, the fruit bag is 30-40% of the light transmittance is appropriate, but if the paper bag is put on the light is blocked, the temperature and humidity is different from the outside air condition outside the envelope, it is dried higher than the outside air during the day, the humidity is high at night There is a problem that the juice is reduced and the flesh feels tough, and the sugar content is lowered by 0.5 ° Bx.

In order to solve such a problem, conventionally, an envelope using a synthetic resin film such as FIG. 1 has been filed (Utility Model Application No. 2000-24866).

Such a synthetic resin bag is formed of a synthetic resin film containing an inorganic material that generates far infrared rays so that the envelope body is breathable, thereby maintaining the breathing action of fruit breathing, the heat heated by sunlight It is an excellent design to preserve fruits longer and to ripen fruits more quickly and uniformly.Because the bags are made of one layer of synthetic resin, they have a higher adhesion to fruit trees than paper bags, and in case of rain or moisture in the air, There was a problem that the adhesive portion of the rotting.

In addition, the insecticide was not mixed with the synthetic resin film, which was exposed to various insects, causing the fruit to be spoiled. There was a problem that farmers have a lot of economic burden.

Accordingly, an object of the present invention is to provide an orchard bag using a synthetic resin, which is further improved by the synthetic resin film prepared by mixing the insect repellent with the insect repellent properties and insect repellent efficiency.

In addition, another object of the present invention is to manufacture a fruit tree in two layers by using the inner skin, such as the outer bag and the paper bag is a synthetic resin film mixed with insect repellent, by forming a plurality of fine vents and drains on both sides of the bottom of the outer shell, It is to provide an orchard bag using synthetic resin which further improves the permeability, sweetness and color of the fruit by further improving the air permeability, the amount of light and the drainage.

Technical means of the present invention for achieving the above object, the outer shell is formed of a synthetic resin film mixed with insect repellent, a plurality of fine vents on the surface of the outer shell, and the arc-shaped drain holes formed on both sides of the lower end of the outer shell And, the inner surface of the outer shell using a paper bag characterized in that the inner shell is formed.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 and 3 show the fruit bag using the synthetic resin according to the present invention, Figure 2 is an external perspective view, Figure 3 is an exploded perspective view, and consists of the outer shell 11 and the inner shell (17).

The outer shell 11 is a synthetic resin film mixed with insect repellent can prevent damage to algae and various insects, the inner shell 17 is a paper bag material excellent in breathability and drainage.

Paper bags used as the endothelial 17 are largely classified into three types according to the coating method, which is divided into wax coated paraffin paper, oil coated oil and water repellent coated water. Any of these may be used but is not limited thereto.

In addition, a plurality of fine vents 15 are formed on the surface of the outer shell 11, and a small drain hole 13 having an arc shape is formed at both bottom edges of the outer shell 11, in particular the outer shell 11 is formed. It is preferable to manufacture with resin of polypropylene (PP) or polyethylene (PE) material.

The upper surface of the fruit bag 10 made as described above is packaged with fruit trees as shown in FIG. 4 by a small fastening means such as a metal pin 20.

On the other hand, the insect repellent mixed in the synthetic resin film 11 is produced by mixing with the film in an encapsulated state, when the encapsulant is encapsulated, the capsule acts as a protective barrier excellent heat resistance and the drug lasts much longer.

Unlike chlorpyrifoss (commonly mixed in banana insect repellent film), the insect repellent is low in toxicity and has little odor, so it is easy to handle. In particular, insect repellents have excellent insect repellent effect against cold blooded animals such as insects, while insect repellents such as mammals such as humans. It does not work. This is because mammals have esterase enzymes that detoxify them when they enter the body.

The fruit bag made in this way is prepared as shown in Figure 5a to 5e.

First, as shown in FIG. 5A, the outer skin synthetic resin film 11 is unfolded and then the inner skin paper bag 17 is unfolded and overlapped on the upper end thereof. Subsequently, the outer shell 11 and the inner shell 17 are folded in half as shown in FIG. 5B, and then the edges (both sides) except for the upper and lower ends are sealed by heat fusion as shown in FIG. 5C. .

Subsequently, as shown in FIGS. 5D and 5E, both bottom edges of the bag are cut to form an arc-shaped drain hole 13, and a plurality of fine vents 15 are formed on the shell 11 by using a tool such as an awl. do.

Such a manufacturing process can be performed collectively by machine automation, and the process is simple and can be performed manually.

The fruit bag using synthetic resin is 15% cheaper than the conventional paper bag, so it can be supplied to farmers at a more economical price (paper bag-18 won / piece, the envelope of the present invention-15.2 won Per unit).

Applicant has investigated and evaluated in various places (maneuvering, insect repellent, fruit characteristics and falling rate, etc.) in various places using such an envelope, the results are as follows.

First, the aid effect of the bag of the present invention is shown in Table 1 below, the comparative example is the case of packing the fruit tree (pear) only with a paper bag, the embodiment is made of a synthetic film 11 and a paper bag 17 This is the case when the fruit trees are wrapped in bags.

☞ Assistance Efficiency (%) = [(No Treatment Damage-Treatment Damage) ÷ Treatment Damage] × 100.

Therefore, as shown in Table 1, the envelope (example) according to the present invention was evaluated to be 66.2% more effective than the conventional paper envelope (comparative example).

In addition, the insect repellent effect of the present invention is shown in Tables 2 and 3 below. Comparative Example 1 is a case of packing the fruit tree only with the synthetic resin film 11 mixed with insect repellent, Comparative Example 2 is a case of packing the fruit tree only with a paper bag, Example is a synthetic resin film 11 and paper mixed with insect repellent It is a case where the fruit tree was packaged by the bag which consists of the bags 17.

Therefore, as described above, the insect repellent efficiency was poor when the fruit was packed only by the synthetic resin film 11 (Comparative Example 1) mixed with the insect repellent, and when the fruit was packed only by the paper bag (Comparative Example 2) Each element had a fairly good fruit characteristic, and in the embodiment, the paper bag 17, which is the endothelium 17, resulted in similar or somewhat improved results as with the paper bag.

In addition, the light emission amount for each color of the shell according to the present invention is shown in Table 6 below. The comparative example is a case where the fruit tree is packaged only with the synthetic resin film 11 with or without the insect repellent, and the embodiment is a fruit tree with the bag made of the synthetic resin film 11 and the paper bag 17 with or without the insect repellent. If you did.

Therefore, as described above, the amount of light transmission by color is not significantly related to whether or not the insect repellent is mixed as in Comparative Examples and Examples, and it is understood that the amount of light emission varies greatly depending on the color of the outer skin 11 and the presence or absence of the inner skin 17. Can be. For reference, the paper bag has a light emission amount of about 20 to 30%, and an optimal light emission amount is 30 to 40%. As shown in the experiment, the yellow and orange-based outer shells 17 of the embodiment are most appropriate, and green and gray and It can be seen that the red skin is also good.

Finally, the fall rate according to the present invention is as shown in Table 6 below, the comparative example is the case of packing the fruit tree only with a paper bag, the embodiment is wrapped fruit tree in an envelope made of a synthetic film 11 and a paper bag 17 If you did.

Bag type Fallover rate [%] 1st time 2nd 3rd Average Comparative example 2.3 3.1 6.9 4.1 Example 2.2 2.9 3.4 2.83

Therefore, as shown in Table 6, the envelope (example) according to the present invention was evaluated to have a fall rate of about 1.27% lower than that of the conventional paper envelope (comparative example).

When comparing the envelope and the paper bag according to the present invention as in the above evaluation example, the present invention shows a very good effect in terms of aid and insect repellent, a somewhat improved effect in the falling rate, and the paper bag in terms of fruit characteristics Similar results were obtained.

On the other hand, when comparing Comparative Example 1 consisting only of the synthetic resin film 11 and Comparative Example 2 consisting only of the paper bag, Comparative Example 1 shows an excellent effect in terms of insect repellent and protection, Comparative Example 2 in terms of fruit characteristics It is much worse than (paper bag).

As described above, by making the fruit bag with the outer skin synthetic resin film 11 and the inner skin paper bag 17, algae such as magpies are not easily torn with claws and beaks, and thus, the aid of the aid can be improved, and the synthetic resin film 11 Insect repellent mixed in the can increase the insect repellent efficiency. For reference, the insect repellent is mixed in the paper bag, but the medicinal effect lasts only about one month, but the insect repellent used in the present invention is encapsulated in the synthetic resin film, so the medicinal effect lasts about six months. Regardless of spraying, the insect repellent efficiency is excellent.

In addition, by using a paper bag as the inner shell 17, forming a plurality of vents 15 on the front surface of the synthetic resin, the outer shell 11, and by drilling the drain holes 13 in the lower edges of both sides, the paper bag is excellent in drainage characteristics Excellent fruit characteristics similar to those of

In addition, the vent 15 is preferably formed so fine (not easily visible to the naked eye) that the algae can not be torn, the fruit 15 is capable of sufficient breathing action and the moisture due to the vent (15) It can be prevented, and the even ripening and excellent fruit characteristics (sweetness, chromaticity, beautifulness, etc.) of an fruit can be ensured.

Accordingly, in the present invention, by making the fruit bag with the outer skin synthetic film and the inner paper bag, algae such as magpies can not be easily torn with claws and beaks to improve the efficiency of the protection, the insect repellent efficiency due to the insect repellent mixed in the synthetic film Can increase.

In addition, by using a paper bag as the inner skin, forming a plurality of vents on the front surface of the synthetic resin, and the drain holes in the both sides of the lower edge, it is excellent in the respiratory action of the drainage and fruit trees, similar to the paper bag, or somewhat improved fruit characteristics There is an advantage you can get.
