Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a fruit bag that is used when cultivating fruits, especially grapes, apples, peaches, etc., and is used to cover the fruit mainly to prevent insect damage. .

(Prior art) Since conventional fruit bags are made of paper, they lack ventilation, and the inside of the fruit bag becomes hot and humid, which can harm fruit growth. There are many. In addition, since it is made of paper, it lacks transparency, making it impossible to observe the growth status of the fruit inside the fruit bag. It has the disadvantage that sunlight must be applied directly to the fruit. Moreover, since the fruit bag was removed, in order to prevent rain from directly hitting the fruit and damaging the fruit,
This also results in the disadvantage that the umbrella-shaped cover must be reapplied.

(Problems to be solved by the invention) The present invention aims to eliminate the drawbacks of conventional fruit bags, and even after the fruit bag is placed on the fruit, the temperature inside the fruit bag remains constant.
In addition to preventing an increase in humidity and preventing the occurrence of diseases, the growth state of the fruit can be observed freely and sufficient growth management can be performed, and the fruit bag can be removed even during the ripening stage of the fruit. To provide a fruit bag that can sufficiently irradiate fruits with sunlight without causing any damage.

(Means and effects for solving the problem) The present invention can maintain good air permeability within the bag body by configuring one side of the bag body with a breathable synthetic resin film, and the fruit bag It is possible to prevent the occurrence of diseases by preventing increases in temperature and humidity inside the plant.

In addition, the present invention has a breathable synthetic resin film forming one side of the bag body, and a group of long thin strips of synthetic resin film arranged parallel to each other with appropriate gaps. By polymerizing and adhering strips arranged in a crosswise direction, the surface of the breathable synthetic resin film is made flat, and despite having ventilation holes, it is difficult to infiltrate rainwater. Even if rainwater does enter the fruit bag, it will be drained immediately and will not accumulate in the fruit bag.

Furthermore, the present invention has a breathable synthetic resin film that forms one side of the bag body, and a group of long and thin strips of synthetic resin film arranged parallel to each other with appropriate gaps. By polymerizing and adhering the strips arranged in such a manner that they cross each other, the surface of the breathable synthetic resin film can be made flat and damage caused by contact with fruit can be prevented.

In addition, with this invention, one side of the bag body is made of a transparent or semi-transparent synthetic resin film, which allows the inside of the fruit bag to be seen through, so the growing state of the fruit can be freely observed and sufficient Growth management can be performed.

Furthermore, in the present invention, by constructing one side of the bag main body with a transparent or translucent synthetic resin film, the fruit can be irradiated with sunlight without removing the fruit bag. Aging, coloring, etc. can be done effectively.

That is, in the present invention, a large number of long thin strips of synthetic resin film are arranged parallel to each other with appropriate gaps, and the parallel strips are made to intersect with each other and are bonded together by polymerization. The structure of a fruit bag is characterized in that a transparent or translucent synthetic resin film is polymerized to a breathable synthetic resin film, and the both sides and lower part of the film are fixed to form the bag body. It is something to do.

(Example) To explain the present invention according to the illustrated example, 1 is a bag body, a breathable synthetic resin film 2,
Each side is made up of a transparent or semi-transparent synthetic resin film 3. The bag body 1 may be gusseted if necessary. The breathable synthetic resin film 2 is made by cutting a synthetic resin film into a large number of thin strips 4, 4... and arranging them in parallel with appropriate gaps. A group of strips are cut into thin strips 5, 5... and arranged in parallel with appropriate gaps, and a group of strips 4, 4..., strips 5, 5... are arranged in parallel. A large number of ventilation holes 6, 6, etc. are formed by polymerizing in crossed directions and gluing or welding the polymerized parts. Commercially available products include, for example, Warif (trade name). (manufactured by Nippon Petrochemical Co., Ltd.). In addition, glittering metal powder such as aluminum may be contained in the synthetic resin film constituting the breathable synthetic resin film 3, or may be vapor-deposited on the surface thereof, and further, glittering metal foil such as aluminum may be attached. It is also possible to provide light reflection performance. The transparent or translucent synthetic resin film 3 may be a polyethylene film, a polypropylene film, or the like, and can be freely selected and used as long as the inner surface can be seen through. Reference numeral 7 denotes a fixing part, which fixes the polymerized peripheral edge of the breathable synthetic resin film 2 and the transparent or translucent synthetic resin film 3 to both sides and the lower part, leaving an opening 8 on the upper side. The fixing means may be adhesive, heat welding, high frequency welding, etc.

The fruit bag of the present invention is constructed as described above, and is used by bagging fruits such as grapes, apples, and peaches.

(Effects of the invention) When using the fruit bag of the invention, one side of the bag body 1 is made of the breathable synthetic resin film 2, so that good air permeability within the bag body 1 can be maintained, and the fruit This has the practical benefit of preventing the occurrence of diseases by preventing increases in temperature and humidity within the bag.

In addition, when using the fruit bag of the present invention, the bag body 1
A breathable synthetic resin film 2 forming one side of the
A strip 4 in which a large number of elongated strips 4, 4... or strips 5, 5... of synthetic resin film are arranged parallel to each other with appropriate gaps. , 4... and strips 5, 5...
Since it is constructed by polymerizing and adhering with the directions crossed, the surface of the breathable synthetic resin film 2 is flat, and even though it has ventilation holes 6, 6... This has the practical benefit of being able to relatively prevent intrusion, and even if rainwater does intrude, the water is immediately drained away and does not accumulate in the fruit bag.

Furthermore, according to the present invention, the breathable synthetic resin film 2 forming one side of the bag body 1 is placed in parallel with the elongated strips 4, 4... or strips 5, 5... of the synthetic resin film at appropriate intervals. A large number of long and thin strips arranged in parallel with each other are overlapped and bonded with the strips 4, 4... and strips 5, 5... arranged in parallel intersecting each other. Therefore, the surface of the breathable synthetic resin film 2 is made flat, which has the practical benefit of preventing damage caused by contact with fruit.

Further, according to the present invention, one side of the bag body 1 is made of a transparent or semi-transparent synthetic resin film 3, so that the inside of the fruit bag can be seen through, and the growth state of the fruit can be observed freely. , it has the practical benefit of being able to perform sufficient growth management.

Furthermore, according to the present invention, one side of the bag body 1 is made of a transparent or semi-transparent synthetic resin film 3, so that sunlight can be irradiated onto the fruit without removing the fruit bag. It has the practical benefit of being able to effectively ripen and color fruits.
