Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective bag for covering fruits such as grapes, pears and apples against pests such as moths, sunburn and wind damage. It relates to a protective bag for fruits that can be removed.

[0002]

2. Description of the Related Art In the cultivation and cultivation of fruits such as grapes, pears, apples, etc., a protective bag is put on the fruits in order to prevent the occurrence of pests, sunburn, and wounds caused by wind damage from the fruit young stage. It is. Most of the protective bags are simple bags made of water-resistant paper, and an example of the related art is shown in FIG.

As shown in FIG. 5 (a), the protective bag is composed of a double bag body 51 having only the upper end opened, and a wrapping piece is provided at the upper end and at the right edge. 52 are provided. The wound piece 52 is formed of the same paper as the bag body 51 and has a thin wire 53 incorporated therein. In such a protective bag, as shown in FIG. 5B, a bunch of grapes 54 is wrapped in a bag body 51, the upper end side is narrowed, and a winding piece 52 in which a wire 53 is sealed is hung from the bunch 54. It is attached by being wound around the branch 55 in double and triple. By wrapping the tuft 54 in the bag body 51 in this manner, the tuft 5
The fruit No. 4 can be protected from pests, sunburn, and wound damage caused by wind damage. At the time of harvesting, the bag 51 can be removed from the tuft 54 by unwinding the winding piece 52 so that the upper end of the bag 51 is opened and pulling down the bag 51 as it is.

[0004]

However, the work of putting the bag 51 over the bunch 54 of fruits such as grapes is performed by a person raising his / her hand with his / her face facing upward and then winding the piece 52 around the branch 55. It becomes the point of winding. In this case, the work of winding the winding piece 52 must perform a complicated movement using both hands,
The work of bagging a large amount of fruit requires considerable effort. In addition, when the bag body 51 is removed at the time of harvesting, the work of rewinding the winding piece 52 in the opposite direction is also performed, so that the work load is similarly increased.

As described above, in the protective bag provided with the winding piece 52, the work of winding and rewinding the winding piece 52 tends to be troublesome, which not only increases the burden on the operator but also reduces the work efficiency. Also have limitations.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fruit protective bag which can be bagged and removed very easily and can greatly improve the working efficiency.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a protective bag in which a front paper and a back paper are overlapped to form a bag. The protruding portion is used as a polymerization allowance, and the front surface paper is formed with a break perforation running vertically from the lower end, and the back paper is formed with a break perforation runs vertically from the lower end with the polymerization allowance. Cut a slit in the center of the width of the
An adhesive layer is formed on each of the polymerization allowance and the surface paper so as to bond when the polymerization allowance is put on the surface paper.

In the present invention, a bag composed of a front paper and a back paper is covered from the lower side of a grape bunch or the like, and the polymerization allowance is bent forward so that the grape pattern enters the slit. By overlapping on paper, the bag can be closed by the adhesive layer via polymerization allowance, and the bunch can be protected from pests, sunburn and wind damage. In addition, when the left and right sides of the front paper and the back paper are pinched and pulled left and right, the paper can be easily torn apart by perforations, and the bag can be easily removed from the tuft.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view of a fruit protective bag according to an embodiment of the present invention, FIG. 2 (a) is a perspective view from the front side, and FIG. 2 (b) is a perspective view from the back side. FIG.

In FIG. 1, a bag 1 of a protective bag is formed by laminating a front paper 2 and a back paper 3 made of water-resistant paper. The width of the front paper 2 and the back paper 3 are the same, but the dimension in the height direction is longer on the back paper 3 than on the front paper 2. The front paper 2 and the back paper 3 are integrally bonded to each other at the left and right end regions indicated by alternate long and short dash lines in FIG.

The front paper 2 has a perforation 2a at the center in the width direction.
To form The perforations 2a extend over the entire length of the surface paper 2 in the height direction, and are formed by continuous points of minute holes. By providing such perforations 2a, the front sheet 2 is easily torn to the left and right at the perforations 2a.

A portion of the back paper 3 that protrudes higher than the front paper 2 is defined as a overlap margin 3a, and a perforation 3b is formed at a position corresponding to the perforation 2a of the front paper 2, and the overlap margin 3a is slit to the outer edge. 3c is an incision.

Further, the back paper 3 is adhered to the front paper 2 and the back paper 3 so that the back paper 3 is bent in the direction of the arrow in FIG. Layers 5 and 6 are applied. The adhesive layers 5 and 6 are bonded when they are overlapped with each other and do not adhere to the paper surface. For example, "Ad Hair Glue" (trade name, manufactured by Mansheng Suzuki Co., Ltd.) can be used.

FIGS. 3 and 4 show the manner in which the protective bag 1 constructed as described above is bagged on grapes.

First, as shown in FIG.
With the upper ends of the front paper 2 and the back paper 3 open, and cover the bunch A of grapes from below. At this time, the slit 3c of the overlap margin 3a of the back paper 3 goes around the handle B projecting from the upper end of the tuft A. Then, FIG.
As described above, the overlapping margin 3a of the back paper 3 is bent toward the near side with a fingertip so that the pattern B enters the slit 3c. When the overlap 3a of the back paper 3 is bent toward the near side, the overlap 3a of the back paper 3 covers the front paper 2 as shown in FIG. 4A, and at the same time, the adhesive layers 5 and 6 overlap and join. Is done.

In this manner, the operation of hanging the bag 1 on the bunch A of grapes simply requires that the polymerization allowance 3a is folded toward the front side after the bag 1 is wrapped from the lower side of the bunch A. For this reason, compared to the operation of winding the winding piece 52 around the handle B as in the conventional example, bagging can be performed easily and in a short time.

When the bag 1 is to be removed, as shown in FIG. 4B, the lower ends of the front paper 2 and the back paper 3 are pinched by a fingertip and pulled left and right. As a result, the perforations 2a and 3b of the front paper 2 and the back paper 3 are torn to the left and right, respectively. Finally, the bag 1 is divided into two pieces at the perforations 2a and 3b, and the bag 1 can be removed from the bunch A of grapes. Therefore, even when the bag body 1 is removed from the tuft A, the work can be quickly performed only by pulling the left and right ends of the bag body 1 with both hands, and the work efficiency is remarkably improved as compared with the work of unwinding the winding piece 52 as in the conventional example. I do.

As described above, with the fruit protective bag of the present invention, the work can be easily performed with both hands when putting on and removing the fruit, and the work of bagging and removing can be completed in a short time.

Although the above embodiment has been described as an example of bagging the grapes bunch A, it is of course applicable to bagging other fruits such as pears and apples.

[0021]

According to the present invention, bagging can be performed simply by covering the bag body from the lower side of a bunch of grapes or the like and bending the polymerization allowance of the back side paper forward. And work efficiency can be significantly improved. In addition, since the work of removing the bag need only be performed by pulling the bag right and left and tearing, the work efficiency can be similarly improved. Further, since a metal such as a wire is not used unlike the related art, there is no need to perform an operation of re-sorting for disposal.
