[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a protective bag used for pest prevention, disease prevention, appearance protection, harvest adjustment, etc. during fruit growing, more specifically, a preferable temperature inside the bag depending on the fruit growing process. The present invention relates to a protective bag that can maintain the above-mentioned properties and is suitable for fruits that grow upward such as loquats.

[0002]

2. Description of the Related Art Conventionally, as a general fruit growing protective bag,
For example, as described in Japanese Utility Model Publication No. Sho 49-13484, it is well known that the bag has ventilation holes at both lower corners. As shown in FIGS. 7 and 8, this protective bag has an upper end portion 101.
In the rectangular bag body 100 in which the lower end portion 102 and the left and right side end portions 103 are adhesively closed by an adhesive material 200 or the like, unbonded portions 104 are provided at the left and right ends of the lower end portion 102, and the bag is hung on the bag. As the fruit F grows and grows, the non-adhesive portion 104 is opened to form the ventilation hole 110, and the opening degree thereof is gradually increased, so that the preferable temperature inside the bag can be maintained. Providing conditions suitable for the fruit growth process in this manner is extremely important for disease prevention, appearance protection, harvest adjustment, and the like.

[0003]

However, according to the above-mentioned conventional protective bag, since the ventilation hole 110 is composed of only the unbonded portion 104 in the lower end portion 102 of the bag body, the growth of the fruit F can be enlarged. The openings of the ventilation holes 110 are not always generated, that is, the lower end portion 10 is caused as the one side and the other side surface portions 100a and 100b of the bag body 100 are bulged due to the growth enlargement of the fruit F.
2 and the left and right side end portions 103 respectively are moved and deformed, and this movement deformation causes the unbonded portion 104 to open, but one and the other unbonded edge portions of the unbonded portion 104 facing each other are formed. Since both 104a and 104b move and deform together with the lower end portion 102, there is a problem that the ventilation hole 110 is difficult to open. If the fruit F swells in the bag with the ventilation holes 110 closed, the high temperature inside the bag may be maintained and many diseases may occur, resulting in a significant decrease in the yield.
Therefore, in the past, it was necessary to artificially open the ventilation hole 110, which was an obstacle to simplification, labor saving, and systematization of the growing work. Furthermore, when the conventional protective bag is covered with a fruit growing upward such as loquat, the vent 110 is opened upward,
There was a problem that rain dew easily entered.

In order to solve the above problems, the applicant of the present invention produced a fruit-growing protective bag as shown in FIGS. 1 and 2. This protective bag has a quadrangular bag body a in which an upper end 2 is opened and a lower end 3 and left and right side ends 4 and 5 are closed.
And the one cut edge 11 that moves and deforms integrally with the lower end part 3 of the bag and the end parts 4 and 5 on the bag side integrally move and deform from both ends of the lower end 3 toward the center of the bag a. A notch 10 including notch edges 11 and 12 facing each other with the other notch edge 12 is provided. Then, after the immature fruit is covered with the bag a, the upper end portion 2 of the opening is closed with the clasp piece 7 for enclosing the clasp 8 and the bag is hooked, and the fruit F grows and grows. As a result, the surface portions a1 and a2 on one side and the other side thereof gradually swell and the lower end portion 3 and the left and right side end portions 4 and 5 are individually moved and deformed. Along with this, one notch edge 11 of each notch 10 is integrally moved with the bag lower end portion 3, and the other notch edge 12 is independently moved and deformed with the bag body side end portion 4 or 5, respectively. One notch edge 1 on the other
Vent holes 13 are surely opened between 1 and 12 (Fig. 2
reference). However, even with such a protective bag, when it is covered with a fruit growing upward such as loquat, the ventilation hole 13 opens upward, and rain dew easily enters. That problem was unsolved. The present invention has been made in view of such conventional circumstances, and its purpose is to ensure that the vent holes are opened along with the growth and enlargement of the fruit, thereby eliminating the need for artificial opening work, and In addition to being able to achieve simplification, labor saving, and systematization of growing work while surely performing prevention, appearance protection, harvest adjustment, etc., when it is covered on fruits growing upward such as loquats. The purpose of the present invention is to provide a protective bag for growing fruits that is difficult for rain dew to enter.

[0005]

In order to achieve the above-mentioned object, the fruit-growing / protecting bag of the present invention comprises a rectangular bag body having an open upper end, and either or both of the left and right sides of the bag body are protected. One notch edge that moves and deforms integrally with the lower end of the bag body from the vicinity of the lower end part of the bag body at the side end portion, and the other notch edge that moves and deforms integrally with the end portion of the bag body. Is characterized in that a notch composed of opposite notch edges is obliquely formed, and a vent hole that is opened as the fruit grows and grows is formed between the notch edges.

[0006]

[Advantageous Effects] According to the above-mentioned structure, the one side and the other side surface portions of the bag body bulge due to the growth and enlargement of the bagged fruits, and the lower end portion of the bag body and the left and right side end portions are individually moved and deformed. ,
One of the cut edges facing each other in the cut is integrally deformed with the lower end of the bag body and the other is integrally deformed with the end of the bag side, so that the vent hole is surely provided between the cut edges of the one and the other. Open.

Further, as the fruit grows and grows, both left and right end portions of the bag body move and deform inward from the initial position, while the lower end portion of the bag body is located at the same position as the initial position. Therefore, when the respective cutting edges move and deform, the cutting edges that move and deform integrally with the bag-side end portion are
It enters into the inside of the cut edge that moves and deforms integrally with the lower end of the bag, and the cut edge around the lower end of the bag forms a chimney-shaped rising piece that surrounds the vent hole, and this rising piece is inside the bag. Plays a role as a guide for discharging hot air, water, and the like, and allows the ventilation hole to more effectively perform a preferable function of maintaining the environment inside the bag. Further, when the bag body is covered with a fruit that grows upward such as a loquat, the lower end side of the bag body is located at the upper side, and the rising portion covers the upper surface side of the ventilation hole to prevent infiltration of rainwater and the like. It will function as a cover.

Further, the rising piece functions as a knob when looking into the bag body through the ventilation hole in order to confirm the coloring degree, ripening degree, etc. of the fruit in the bag, and further when removing the bag body. If the rising piece is grasped and pulled along the oblique cut, the bag can be quickly torn without damaging the fruit powder, the hair or the like.

[0009]

Embodiments of the protective bag of the present invention will be described below with reference to the drawings. First, as briefly described in the section of the prior art, the reference examples shown in FIGS. 1 and 2 will be described in detail. In the bag a of the reference example, a rectangular sheet of paper cut into an appropriate size is folded in two, and a matching edge (upper edge in FIG. 1) facing the folding edge and an adjacent folding edge are formed. And an edge (the left edge in FIG. 1) are bonded together with an adhesive 1 to open the upper end 2 and to form a quadrangular shape in which the lower end 3 and the left and right side ends 4 and 5 are closed. It

A notch 6 is formed in a substantially L-shape in the vicinity of the upper end portion 2 of the side end portion 4 to which the adhesive is adhered to form a stopper piece 7, and the stopper piece 7 has a required length. Adhere and seal the stopper plate 8. Further, both end portions of the lower end portion 3 of the bag body a are unbonded portions 9 and 9, and are moved and deformed integrally with the bag body lower end portion 3 from each unbonded portion 9 toward the center of the bag body a. The notch 11 and the other notch 12 that moves and deforms integrally with the bag-side end portions 4 and 5 are provided with the notch 11 and 12 facing each other, and the notch 10 having a required length is formed obliquely.

According to this structure, after the immature fruit is covered with the bag body "a", the clasp 8 for enclosing the stopper 8 is provided.
When the upper end portion 2 of the opening is closed and bagging is performed, as the fruit F grows and grows in the bag body a, the surface portions a1 and a2 on one side and the other side thereof gradually swell and the lower end portion 3 and the left and right sides are gradually expanded. Both ends 4,
5 are individually moved and deformed. Along with this, cut 10
One of the cut edges 11 in is integrally formed with the lower end portion 3 of the bag body,
The other cut edge 12 is integrated with the bag-side end 4 or 5,
Since they are individually moved and deformed, the vent holes 13 are surely opened between the cut edges 11 and 12 of the one and the other (see FIG. 2).

At this time, the lower end portion 3 of the bag body a is moved and deformed inward from the initial position, while the left and right side end portions 4 and 5 are located at substantially the same positions as in the initial position, and therefore, the respective positions are maintained. When the cut edges 11 and 12 are moved and deformed, the cut edges 11 that move and deform integrally with the lower end portion 3 of the bag body are the left and right side end portions 4 and 5.
The rising edge portion 14 is formed into a chimney-shaped rising piece portion 14 that surrounds the ventilation hole 13 around the cutting edge 12 on the side end portions 4 and 5 by entering the inside of the cutting edge 12 that moves and deforms integrally with the cutting edge 12. Plays a role as a guide for discharging hot air, moisture and the like in the bag body a, and allows the ventilation hole 13 to more effectively perform the function of maintaining a preferable bag environment.

Further, in this example, since both ends of the lower end portion 3 of the bag body are the non-adhered portions 9 as described above, the cut edges along with the movement deformation of the lower end portion 3 of the bag body and the side end portions 4 and 5. The 12 is moved and deformed so as to expand to the left and right, so that the opening of the ventilation hole 13 is made more reliable and the rising piece
It is possible to promote the above-mentioned guiding action by the 14.
Even if the notch 10 having the required length is formed obliquely from both ends of the lower end portion 3 of the bag body to the center direction of the bag body a without forming the non-adhered portions 9 to achieve the initial purpose. It goes without saying that a sufficient effect can be obtained. In this example, as described above, the vent holes 13 are surely opened with the growth and enlargement of the fruit F, and the preferable temperature inside the bag can be maintained. Thus, advantageous effects are obtained as compared with the conventional protective bag. However, when covered on a fruit growing upward such as loquat, the vent hole 13 is opened upward, and the problem that rain dew or the like easily enters has not been solved.

The present invention is intended for fruit growth, in which, in addition to the fact that the vent holes are surely opened as the fruit grows and grows, rain dew or the like is difficult to penetrate when it is covered on a fruit growing upward such as loquat. The present invention will be described below with reference to FIGS. 3 and 4, 5 and 6. In the embodiment shown in FIGS. 3 and 4, a rectangular sheet cut into an appropriate size is folded in two, and both edges (upper and lower edges in FIG. 3) adjacent to the folded edge are bonded together. Adhesive agent 20 is formed to open a top end 21 and to form a rectangular bag a ′ in which a bottom end 22 and left and right side ends 23 and 24 are closed. At the opening of the bag a ', one edge of the upper end 21 is extended to form a sealing surface 25. An adhesive 26 that maintains a semi-dried state is previously applied to the sealing surface 25 and the contact portion when the sealing surface 25 is folded back to close the upper end portion 21.

The lower end 22 of the bag body at the one side end 24
The end portion on the side is an unbonded portion 27, and one notch edge 31 that moves and deforms integrally with the bag body lower end portion 22 from the unbonded portion 27 toward the center of the bag body a ′ and the bag body side end portion 24. A notch 30 having a required length composed of notch edges 31 and 32 opposed to the other notch edge 32 that moves and deforms integrally with is formed obliquely.

In this embodiment, therefore, the sealing surface 25 is folded back after the immature fruit is covered with the bag a '.
The upper end portion 21 of the opening is sealed by adhering with 26 and the bag is hung. As the fruit F grows and grows in the bag a ′, the one side and the other side surface portions a′1 and a′2 gradually swell and the lower end portion 22 and the left and right side end portions 23 and 24 move individually. Deform. Along with this, one notch edge 31 of the notch 30 is integrated with the bag body lower end portion 22, and the other notch edge 32 is the bag body side end portion 24.
Since they are individually moved and deformed separately,
The ventilation hole 33 is surely opened between the other cut edges 31 and 32 (see FIG. 4).

Further, at this time, the end portion 24 on the side of the bag body is moved and deformed in the direction of entering from the initial position, while the lower end portion 22 of the bag body has its both end portions at substantially the same positions as in the initial position, and therefore, the above respective When the cut edges 31, 32 of the bag are moved and deformed, the cut edge 32 that moves and deforms integrally with the bag side end portion 24 enters the inside of the cut edge 31 that moves and deforms integrally with the bag body lower end portion 22 and The cut edge 31 on the side of the portion 22 forms a chimney-shaped rising piece 34 surrounding the ventilation hole 33, and the rising piece 34 serves as a guide for discharging hot air, moisture, etc. in the bag a. The function of maintaining the preferable environment inside the bag by the air holes 33 is more effectively performed. Further, when the bag body a is covered with a fruit F which grows upward such as a loquat, the lower end portion 22 side of the bag body is located at the upper side and the rising portion 34
Serves as a cover that covers the upper surface side of the ventilation hole 33 and prevents the entry of rainwater and the like.

Further, in this embodiment, since the unbonded portion 27 is provided as described above, the lower end portion 22 of the bag body and the side end portion 24 are
With the movement deformation of the cutting edge 31, the cutting edge 31 is moved and deformed so as to expand to the left and right, so that the opening of the ventilation hole 33 is made more reliable and the above-mentioned guiding action by the rising piece portion 34 can be promoted. Needless to say, even if the notch 30 is formed without providing the unbonded portion 27, sufficient operational effects to achieve the initial purpose can be obtained.

Next, the embodiment shown in FIGS. 5 and 6 will be described. This embodiment is a modification of a part of the embodiment shown in FIGS. That is, the bag body a ″ is formed in substantially the same manner as the bag body a ′ shown in FIG. 3, but shown in FIG. 1 instead of the sealing means (sealing surface 25, adhesive 26) of the opening upper end portion 21. While adopting a mouth-fastening means (a notch 6, a mouth-fastening piece 7, a stopper plate 8), the unbonded portion 27 and the notch 30 described above are provided on the other side end portion 23.
Is also provided.

Thus, in this embodiment, after the immature fruit is covered with the bag a ", the opening upper end portion 21 is closed with the closing piece 7 for enclosing the stopper plate 8 and the bag is hooked. The bag a "is formed on the one side and the other side a" as the fruit F grows and grows.
1, a ″ 2 gradually swells to lower end 22 and left and right end portions 23,
24 are individually moved and deformed, so that one notch edge 31 is integrally moved with the bag lower end portion 22, and the other notch edge 32 is integrally moved with the bag body side end portions 23 and 24, respectively, so that they are independently moved and deformed. The vent hole 33 is surely opened between the cut edges 31 and 32 (see FIG. 6).

At this time, the bag-side end portions 23 and 24 are moved and deformed inwardly from the initial position, whereas the bag lower end portion 22 has both end portions in substantially the same positions as in the initial position. When the respective cut edges 31, 32 are moved and deformed, the cut edges 32 that move and deform integrally with the bag body side end portions 23, 24 enter the inside of the cut edges 31 that move and deform integrally with the bag lower end portion 22, Vents around the cut edge 31 on the lower end 22 of the bag
A chimney-shaped rising piece 34 is formed around 33, and the rising piece 34 serves as a guide for discharging hot air, moisture, etc. in the bag a as in the above-described embodiment, and the ventilation hole 33 is formed.
It covers the upper surface side of the and functions as a cover for preventing infiltration of rainwater and the like.

Also in this embodiment, the unbonded portion 27
The openings 33, 33 are more surely opened, and the guiding action of the rising piece 34 can be promoted, and it is sufficient to achieve the initial purpose without providing the unbonded portion 27. It goes without saying that the action and effect can be obtained.

The construction of the bag body and the method of forming the bag body in the protective bag of the present invention are not limited to those described in the above-mentioned embodiments, but a square with the upper end opened and the lower end and left and right side ends closed. Any shape is acceptable. Further, the means for tightening the upper end of the opening in each embodiment is not limited to the one shown in the figure, and various well-known mouth tightening means can be adopted.

Further, in the reference example shown in FIGS. 1 and 2, since the rising piece portion 14 surrounds the side of the ventilation hole 13, the ventilation hole 13 comes to be positioned downward by bagging, that is, it faces downward. It is suitable for use on fruits such as apples and pears that grow on the other hand, and on the other hand, in the embodiment of the present invention shown in FIGS. 3, 4 and 5, 6, since the rising piece portion 34 surrounds the upper side of the ventilation hole 33, As described above, the ventilation holes 33 are positioned above by hanging, that is, the ventilation holes 33 are suitable for use on fruits such as loquat growing upward.
