Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a double-fruit bag used for fruits such as peaches, which have a significantly short peduncle.

[0002]

[Prior art]

 Conventionally, fruit bags used for fruits such as peaches, plums, etc., which have a significantly short peduncle and bear fruit in a manner intimately attached to the branches, are, for example, Jikken 2-333495, Jikken 2-4114 or Jikken. As in Japanese Patent Laid-Open No. 2-42115, a double structure having a light-transmitting inner bag directly bound to a branch and a light-shielding outer bag fixed to the inner bag via an adhesive piece. It has been known.

[0003]

[Problems to be solved by the device]

 The known double-structured fruit bag suppresses the chlorophyll production of the fruit by covering the majority of the fruit growing period with a light-shielding outer bag, and then only the outer bag at a certain time immediately after harvesting. It is removed and kept covered with a translucent inner bag to protect the plant from pests and late infections while promoting the coloring of fruits. In the case of this publicly known fruit bag, in order to make it easy to remove only the outer bag, the tear line is one side and the other side is multiple cut lines or two sides protruding from the upper edge of the outer bag. A piece is provided, the inner bag and the outer bag are bonded to each other via the adhesive piece, and a tear line is provided in the vertical direction of the outer bag.

However, since the tear line has a large number of joints, when the tear line is gradually torn from the end, the resistance is small and the tear line can be relatively easily torn, but when the whole tear line is torn at once. Requires relatively large force. Therefore, in the case of an adhesive piece that has a tear line as a component as described above, if the tear line between the adhesive piece and the outer bag is torn by pulling on the bottom of the outer bag, the fruit and inner bag will be damaged. There was a risk of giving.

In addition, Japanese Utility Model Publication No. 2-42115 discloses a double fruit bag shown in FIG. 3, and this double fruit bag has an opening upper edge portion 20 of an outer bag, as shown in FIG. When the portion surrounded by the slit line 21 and the notch 22 is used as the adhesive piece 23, the notch 22 reaches the upper edge portion of the opening, so that the adhesive piece portion is flapping. As a result, there was a problem in that when the double fruit bag was used, the adhesive piece portion was blown by the wind and was cut up to the tear line, so that the light-shielding effect of the outer bag was reduced.

In view of the above, the present invention is capable of stably holding the outer bag until a certain period of time immediately before the harvest and sufficiently achieving the light-shielding effect, and at that time, the outer bag can be easily removed with one hand. The purpose of the present invention is to provide a double fruit bag capable of promoting coloring of fruits.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the double fruit bag according to the present invention has an inner bag and an outer bag formed to be shorter in the upper and lower direction of the inner bag, and the lateral length of the inner bag is set to the outer bag. On the other hand, in a double fruit bag that is formed to be substantially larger than the outer bag and has a notch for inserting a fruit tree branch in the center of the upper edge of the inner bag that is exposed from the outer bag, the upper end is wide and the lower end is wide. The two score lines were formed so that the space between the parts was narrower than that in the vertical direction and the upper end reached a position slightly lower than the upper edge of the opening of the outer bag. The inner bag and the outer bag were joined to each other by using the part surrounded by the two score lines and the upper edge of the opening of the outer bag as an adhesive piece and adhering the adhesive piece to the inner bag. That is, cut away from this adhesive piece in the upper and lower edges from the upper edge to the lower edge of the outer bag. Here, characterized in that a line, and the lines constituting the two score line, not only straight, curved, even Jiguza grayed rays including. Specific examples of the two score lines include an inverted C-shaped score line. Further, the upper end of the score line forming the adhesive piece must be stopped before reaching the upper edge of the opening, and a distance between the lower ends of the two score lines is also required to some extent. The amount of the uncut portion 14 left depends on the material of the outer bag, but in general, the former is preferably about 1 to 3 mm and the latter is preferably about 2 to 4 mm. In any case, it is sufficient that the uncut portion is left so that the outer bag can be easily removed with one hand. .

As described above, the outer bag has two uncut portions 14 between the upper end of the cutting line and the upper edge of the opening, and one uncut portion between the lower ends of the two cutting lines. It is connected to the adhesive piece at three points of 14. With this configuration, when the outer bag is pulled from below, the notch-not-formed portion 14 is broken, and the outer bag can be easily removed. In this case, as compared with the case where two notch lines are continuous and the notch not formed portion is two places between the notch line upper end and the opening upper edge, the two notch lines lower end Since there is an uncut portion between the parts, there is no concern that the adhesive will be applied across the cut line at that portion, and it is easy to widely apply the adhesive to the adhesive piece and one uncut portion. Since the outer bag has a large amount, the outer bag can be more stably adhered via the adhesive piece, which has the effect of increasing resistance to wind. As a result, the double fruit bag of the present invention can be used stably even in a windy region.

Further, since the inner bag has a lateral length substantially larger than that of the outer bag, the inner bag is provided with a vertical fold and accommodated in the outer bag. The outer bag is formed to be shorter than the inner bag in the up-down direction, but it is preferable that the upper edge opening of the outer bag is arranged at least 20 mm below the opening of the inner bag.

Further, the adhesive piece can be provided only on the front side of the outer bag or on the front side and the back side, and the tear line in the vertical direction from the upper edge portion to the lower edge portion of the outer bag at a position apart from the adhesive piece. To provide. This tear line is formed by a pressure line by roulette.

The double fruit bag constructed as described above not only has an outer bag that can be easily removed with one hand, but also does not have a notch that reaches the upper edge of the outer bag and that the outer bag is far from the notch. Since the upper and lower tear lines are provided in the container, the shielding effect of the outer bag does not decrease due to tearing of the tear lines by the wind.

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a double fruit bag according to the idea of claim 1. The double fruit bag 1 comprises an outer bag 2 and an inner bag 3, both of which are joined by an adhesive piece 4. are doing.

The adhesive piece 4 is formed from an inverted c-shaped cut line 6 formed between two points located slightly below the upper edge 5 of the outer bag opening and a portion surrounded by the upper edge of the outer bag opening. , And its backside is coated with adhesive. In the case of this example, the distance between the upper end of the inverted C-shaped cut line 6 and the upper edge 5 of the outer bag opening is 2 mm, and the distance between the lower ends of the cut lines is 3 mm. The distance between the upper ends is 15 mm.

The outer bag 2 is made of paper having a light-shielding rate of 50% or more, and the bottom of the outer bag 2 is closed by an adhesive portion 7 leaving a drainage port 8 partially. The inner bag 3 is formed of a white or light paraffin wax paper or a resin film into a tubular shape.

The inner bag 3 has a lateral length substantially larger than that of the outer bag 2. Therefore, the inner bag 3 is accommodated in the outer bag 2 by providing vertical pleats 9 on its side surface.

Actually, after forming the score line and the tear line on the outer bag in the expanded state, an adhesive is applied at a predetermined position, and the bag is formed while folding the fold of the outer bag, and at the same time, the adhesive piece is formed. The process of adhering the inner bag and the inner bag is automatically and continuously performed.

The double fruit bag thus constructed is used as shown in FIG. That is, after storing the fruit a inside the bag, the branch b of the fruit tree is inserted into the U-shaped notch 10 provided at the center of the upper edge of the opening on the front side and the back side of the inner bag 3. The upper edge portion of the opening of the inner bag 3 is converged with, and the converging portion is bound with the wire 12 sealed on the upper portion of the body portion bonding margin 11 of the inner bag 3.

When the fruit a grows and grows to a certain size or more after a certain period of time, the tear line 13 of the outer bag 2 is broken by the pressure, and the vertical folds 9 of the inner bag 3 are released. After that, by pulling the bottom of the outer bag below the adhesive piece, only the outer bag can be easily removed with one hand.
