Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fruit bag which can protect fruits such as apples and prevent the occurrence of diseases.

[0002]

2. Description of the Related Art In order to protect fruits from damage by wind, rain, birds, insects, etc., a hanging bag for fruits covers at least until the fruits are appropriately sized. Conventionally, in addition to such a function, in order to prevent diseases such as spot disease, soot disease, soot spot disease and the like, a hanging bag made of paraffin paper containing various pesticides is used.

In recent years, however, resistant bacteria to pesticides have appeared, making it difficult to increase the bactericidal effect, and phytotoxicity caused by pesticides has become a problem.

[0004]

The present invention is highly safe for fruit producers and consumers, can effectively use wood waste, has a good bactericidal effect, and has a long-term effect. The object is to provide a hanging bag for fruits that lasts.

[0005]

[Means for Achieving the Object] The fruit hanging bag of the present invention comprises:
In order to achieve the above object, an antibacterial substance extracted from a plant is contained. This antibacterial substance may be mixed with the applied water repellent and may be sprayed from the outer surface.

In a multi-layer bag having an inner bag made of paraffin paper, the base paper of paraffin paper may be impregnated with an antibacterial substance or may be mixed with paraffin. Further, the antibacterial substance may be mixed with the base paper forming the outer bag.

[0007]

[Function] The bag protects fruits from wind and rain, birds, etc. in the same manner as before, and the antibacterial substance prevents diseases and insect damage.

[0008]

EXAMPLE As shown in FIGS. 1 and 2, a fruit hanging bag 1 is composed of an outer bag 2 having a light-shielding property and an inner bag 3 made of translucent paraffin paper. The front surface paper 4 and the back surface paper 5 are adhered to each other through the margins 6 provided on both side edges of the back surface paper 5 to form a bag having an open upper end. Also,
A semi-circular cutout portion 7 is formed at the center of the upper end of the hanging bag 1 for fruits on the side of the front surface paper 4, and the length from the bottom of the cutout portion 7 is 2 to 2 below.
A notch 8 of 3 cm is formed.

On both sides and the center of the front surface paper 4 and the back surface paper 5 of the outer bag 2, broken lines 9 are formed in parallel with each other. Further, a stopper 10 such as a wire for binding the opening of the bag body 1 is attached between the side edge of the front surface paper 4 and the margin 6.

The inner bag 3 is a bag having a size slightly smaller than the outer bag 2 and having an open upper end. The paraffin paper forming the inner bag 3 is an antibacterial substance extracted from plants in paraffin applied to the base paper. Is mixed in. Examples of the antibacterial substance include hiba oil, cedar oil, cypress oil, and Menso bamboo extract extracted from hiba, cedar, cypress, and Menso bamboo, and hinokitiol obtained from hiba oil and hinoki oil, and quinone obtained from Menso bamboo extract. Derivatives are used.

It should be noted that the antibacterial substance is not mixed with paraffin,
The base paper before applying paraffin may be impregnated. Further, the inner bag 3 may be made of another paper material such as hatron paper, and the inner bag 2 may be coated with a water repellent agent containing the above-mentioned antibacterial substance.

Further, when the base paper constituting the outer bag 2 is carded, it is possible to mix the above-mentioned antibacterial substance into the outer bag 2 so that the outer bag 2 contains the antibacterial substance. A liquid medicine can also be applied. Further, after forming the bag body, the antibacterial substance may be sprinkled from the outer surface, or another intermediate bag may be sandwiched between the outer bag 2 and the inner bag 3 to form a multi-layer bag having three or more layers.

To cover the fruit with the fruit hanging bag 1 of the above embodiment, the upper end of the bag is opened, and then the fruit is stored inside and the handle of the fruit is cut from the notch 8 as shown in FIG. It is taken out of the bag and the opening end of the fruit hanging bag 1 is bound by the stopper 10. When the fruit inside has grown to a certain extent, the outer bag 2 is broken from the cut line 9 to remove the bag, and the fruit is exposed to sunlight.

Then, during the development of the fruit, the inner fruit is protected from wind and rain, birds, etc. by the bag body,
Antibacterial substances prevent disease and insect damage. FIG. 4 shows the minimum inhibitory concentrations of the antibacterial substances, hiba oil and hinokitiol, used in the above Examples against various fungi. This shows that Hiba oil and hinokitiol exert an antibacterial effect even in a small amount.

Further, in the above-mentioned embodiment, when the solution of hinokitiol crystal powder is used as an antibacterial substance, since the hinokitiol crystal powder is difficult to dissolve in water, it is used in combination with acetic acid, lactic acid, succinic acid, citric acid, salt, weak hydrochloric acid, etc. To increase the solubility, or it is included in cyclodextrin to facilitate the solubility. In addition, the bag for fruit is not a multi-layer bag,
An antibacterial substance may be contained in a single-layer fruit bag made of translucent paper in the same manner as in the above embodiment.

[0016]

INDUSTRIAL APPLICABILITY The fruit hanging bag of the present invention can protect the fruit from wind and rain, birds, etc. by the bag like the conventional bag, and can prevent the occurrence of disease and insect damage by the antibacterial substance. It is possible, and the antibacterial effect lasts for a long period of time as compared with the case of directly spraying the pesticide on the fruit. In addition, since the antibacterial substances used are those extracted from plants, it is possible to effectively use the wood waste materials that were previously disposed of, and despite the high bactericidal effect, acute toxicity and sudden Side effects such as mutagenesis are extremely low, safety is high, and resistant bacteria are unlikely to occur. Furthermore, when harvested and stored with the semitransparent bag containing the antibacterial substance covered, the generation of mold is suppressed and the shelf life is improved.
