Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a double fruit bag used for fruits such as peaches, which are particularly susceptible to pests and have extremely short stems.

b. Prior Art In general, fruits such as peaches and plums have significantly shorter stems than fruits belonging to the pome family, such as apples and pears, and the fruits bear fruit tightly attached to branches. unable to unite. Therefore, conventionally, a roughly U-shaped notch is provided at the upper edge of the opening of a fruit bag used for such fruits, and after inserting a branch above the fruit into the notch, The open end was tied up.

By the way, the purpose of hanging fruit bags on peaches etc. is as follows.
To control pests and diseases that attack fruits, especially pests such as gray rot, homopress rot, etc., and pests such as peach weevils and sink beetles, to prevent damage caused by these, and to give the fruits an elegant finish by applying coloring with high commercial value. It is in. Therefore, the fruit bag has a double structure, and the fruit is covered with a light-blocking outer bag for most of the growing period to suppress the production of chlorophyll in the fruit.Then, just before harvest, only the outer bag is peeled off. In addition to promoting coloration of the fruit on its own skin while covered with a translucent inner bag that is difficult for rain to penetrate, the fruit was also intended to prevent damage to the fruit caused by late-stage infection. In addition, oil peaches (nectarines), which have been increasingly cultivated in recent years, do not have hair on their skins, so if the fruit is exposed to direct sunlight, raindrops adhere to the fruit surface for a long time, or dew condensation occurs, the fruit will crack. Otherwise, the product value will be significantly reduced due to abnormal coloring such as "yellow mottling". Therefore, the fruit bag should be made with a double layer structure, and after the outer bag is peeled off, the inner bag is made of a translucent material that prevents rain and dew from penetrating until the time of harvest. It was necessary to keep the bag securely hung to secure the fruit.

C. Problems that the invention aims to solve However, in the case of conventional double fruit bags,
As mentioned above, since the open end of the fruit was tied above the branch, it was not possible to remove only the outer bag accurately and efficiently during the limited ripening period, and
There was a risk of damaging the inner bag when peeling off the outer bag.

The present invention was made to solve the problems of the above-mentioned prior art, and its gist is as follows:
An inner bag and an outer bag formed shorter than the inner bag are overlapped, and the length of the inner bag in the lateral direction is substantially larger than the outer bag, and the inner bag is exposed from the outer bag. In the double fruit bag, an adhesive piece is provided protruding from the upper edge of the opening on the opposing surface of the outer bag, and A notch is provided at the bottom opposite to the adhesive piece, and a first tear line is provided on an extension line of the upper edge of the opening located at the base of the adhesive piece, and a first tear line is provided from the base of the adhesive piece to the notch at the bottom. A second tearing line extending in the vertical direction is provided, and the inner bag and outer bag are fixed to each other via the adhesive piece.

d. Means for Solving the Problems The present invention will be explained in detail below based on illustrated embodiments.

Figures 1 to 3 show one embodiment of the present invention. In the figures, a double fruit bag 1 has an inner bag 2 and an outer bag 3.
The inner bag 2 is provided with a substantially U-shaped cutout 4 at the center of the upper edge of the opening on the front and back sides. This notch 4 is for inserting a branch b of a fruit tree when bagging the fruit a. However, by providing the above cutout 4,
Notches 4 should not be provided in areas where there is a risk of promoting infections such as peach blight and peach perforation.

Further, the inner bag 2 is provided with vertical pleats 5 on opposing sides, and these vertical pleats 5 allow the inner bag to
The lateral length of the outer bag 3 is substantially larger than the lateral length of the outer bag 3.

On the other hand, the outer bag 3 is formed to be shorter than the inner bag 2, and is configured as a bottomed bag by fixing the adhesive part 7 using a peelable adhesive disposed on the bottom part 6 of the outer bag 3. . The upper edge opening 8 of the outer bag 3 is
It is arranged at least 20 mm below the opening 9 of the inner bag 2. In addition, the outer bag 3 has a triangular adhesive piece 10 protruding from the upper edge openings 8 facing each other on the front side and the back side, and a bottom part 6 facing the adhesive piece 10 for easy peeling. A notch 11 is provided for this purpose. The adhesive piece 10 is used to fix the inner bag 2 and the outer bag 3 by applying adhesive thereto, and has a first tear line on the extension line of the upper edge of the opening of the outer bag 3 corresponding to the base. 12a is provided, and the outer bag 3 can be easily peeled off from the joint between the inner bag 2 and the outer bag 3 along this tear line 12a. Note that the shape of this adhesive piece 10 is not only triangular but also polygonal,
It can be semi-circular and base shaped.

Further, on the front side and the back side of the outer bag 3, a second tear line 12b is provided over the entire length in the vertical direction from the base of the adhesive piece 10 to the upper end of the notch 11. The tear lines 12a, 12b are desirably formed by pressure wires applied from the inside of the outer bag 3 using a roulette so as not to impede the light-shielding properties as much as possible.

Reference numeral 13 denotes a clasp for tying sealed at the above-mentioned end of the body part attachment allowance 14 of the inner bag 2; 15, the body part attachment allowance of the outer bag 3; 16
are drainage holes provided at both lower corners of the outer bag 3.

In this embodiment, the inner bag 2 is formed by pasting white or light-colored paraffin wax paper or resin film into a tube, and the outer bag 3 is made of paper having a light shielding rate of 50% or more and is shaped like a tube. Or it is formed into a bag shape.

The double fruit bag 1 having the above structure is used as follows. That is, as shown in FIG. 2, after the fruit a is stored inside the bag, a branch b of a fruit tree is inserted into the notch 4 of the inner bag 2, and then the open end of the inner bag 2 is inserted onto the branch b. The bagging work is completed by converging the parts and tying the bundled parts with the clasp 13.

Next, after a certain period of time has elapsed, the fruit a inside the double fruit bag 1 grows and enlarges, and accordingly, the inner bag 2 expands in horizontal length while releasing the vertical folds 5. On the other hand, the length of the outer bag 3 in the horizontal direction is the same as that of the inner bag 2.
Since the fruit a is shorter than the slit, it is torn along the tear line 12a due to the pressure from the inside due to the enlargement of the fruit a, and the adhesive piece 10, which is the adhesive part between the inner bag 2 and the outer bag 3, is torn along the tear line 12a.
The base of the cut was also torn from the tear line 12a, and finally,
As shown in FIG. 3, the outer bag 3 is separated from the inner bag 2 and falls, leaving only the adhesive piece 10 behind. In case, outer bag 3
tear line 1 from notch 11 even when the
When tearing upward along line 2b, outer bag 3 becomes inner bag 2.
It can be easily peeled off.

Thus, as shown in FIG. 3, since the double fruit bag 1 consists of only the inner bag 2, the inner bag 2 is made of a translucent material to allow sunlight to pass through the inner bag 2 to the fruit a. It is possible to bathe the fruit, thereby promoting its coloration, increase in sugar content, and development of ripeness. In addition, since the inner bag 2 can be left hanging until the fruit a is harvested, the fruit a can be protected from contamination by pests, harmful birds, and sprayed agricultural chemicals.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, in the embodiment described above, the adhesive piece 10 was provided at one location on the front side of the outer bag 3 as shown in FIG. 1, but a similar adhesive piece 10 was also provided on the back side of the outer bag 3. It's okay. By providing the adhesive pieces 10 at two locations in this manner, the bonding force between the inner bag 2 and the outer bag 3 can be increased, and durability against wind pressure and the like can be increased.

e Effects of the invention As mentioned above, the double fruit bag according to the invention has an adhesive piece protruding from the upper edge of the opening of the outer bag, and a notch at the bottom opposite to this adhesive piece. A first tear line was provided at the base of the adhesive piece, and a second tear line was provided from the base of the adhesive piece to the bottom notch, so that the inner bag and the outer bag were fixed together via the adhesive piece. Therefore, the inner bag and outer bag can be stably attached, and by pulling the bottom of the outer bag downward with one hand, the inner bag can be removed without damaging the adhesive and leaving the adhesive piece behind. Only the bag can be peeled off extremely easily and quickly, and the efficiency of the outer bag removal work can be improved. Moreover, most of the outer bags naturally peel off from the inner bags as the fruit grows and enlarges, so the peeling process can be omitted.
Economically advantageous. Since the inner bag protects the fruit from diseases, bird damage, and contamination from sprayed pesticides until the time of harvest, it is possible to obtain fruit of good quality.
