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]

 In the above-mentioned double-structured fruit bag, most of the fruit growing period is covered with a light-shielding outer bag to suppress chlorophyll production of the fruit, and then only the outer bag is removed at the time of harvest. However, it is necessary to promote the coloring of fruits while protecting them from pests and late infections while still being covered with a transparent inner bag. As a method for removing only the outer bag, in the above-mentioned publication, a tear line or a combination of a tear line and a notch is provided between the adhesive piece and the outer bag.

However, since the tear line has a plurality of joints, a larger force is required when the whole tear line is torn at once than when the tear line is gradually torn from the end of the tear line. Therefore, when the tear line between the adhesive piece and the outer bag is torn by pulling the bottom of the outer bag as described above, the fruit and the inner bag may be damaged.

Further, as shown in FIG. 4, when the portion surrounded by the opening upper edge portion 20, the tear line 21 and the notch 22 of the outer bag is used as the adhesive piece 23, the notch 22 is formed at the opening upper edge portion. Since it has reached the limit, flapping of the adhesive piece occurred. As a result, it is said that when the adhesive piece 23 is adhered to the inner bag 24, adhesion failure occurs, or when the double fruit bag is used, the adhesive piece part is blown by the wind and is cut to the tear line, thereby reducing the light-shielding effect. Had problems.

An object of the present invention is to provide a double fruit bag in which the outer bag can be easily removed with one hand while keeping the light shielding effect.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention overlaps an inner bag of a double fruit bag with an outer bag formed to be shorter than the inner bag in a height direction, and sets the lateral length of the inner bag to the outer bag. The upper edge of the outer bag has a notch for inserting fruit tree branches in the center of the upper edge of the inner bag that is exposed from the outer bag. Form a continuous notch between two points located slightly below the part, and use the upper part of this notch as an adhesive piece, and bond this adhesive piece to the inner bag to make the inner bag and outer bag mutually It is characterized in that it is joined and a tear line is provided 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.

Further, it is also possible to form a protruding piece on the upper side of the notch so as to protrude upward from the upper edge portion of the opening of the outer bag, and to use an adhesive piece on the upper side of the notch including the protruding piece. .

As described above, the outer bag is connected to the adhesive piece at two uncut portions notched between the notch and the upper edge of the opening or the edge of the protruding piece. In either case, the uncut portion is broken by pulling from below the outer bag, and the outer bag can be easily removed, but the outer bag is more stable when the pop-out piece is provided.

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 is housed in the outer bag. The outer bag is formed to be shorter in the height direction than the inner bag, and the upper edge opening of the outer bag is arranged at least 20 mm below the opening of the inner bag. The outer bag is the front side only or the front side. Also, it is joined to the inner bag by an adhesive piece provided at the upper edge opening portion on the back side facing each other.

When the protruding piece is provided, its shape can be an arbitrary shape such as a triangle or a polygon. The notch can be formed by an arbitrary shape such as a straight line, a broken line, or a curved line between any two points located slightly below the upper edge of the opening, but a U shape or a V shape is taken into consideration in consideration of the adhesion area. It is desirable to form it in a letter shape.

Further, the notch does not reach the upper edge of the opening or the edge of the projecting piece and must be stopped before this. The extent to which the uncut portion is left depends on the material of the outer bag, but it is generally desirable to be about 1 to 3 mm. In any case, it is necessary to leave uncut portions so that the outer bag can be easily removed with one hand.

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 is vertically provided 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 can be easily removed with one hand, and since it does not have a notch reaching the upper edge of the outer bag, the double-fruit bag has an adhesive piece and an inner bag. No joint failure occurs, and since the upper and lower tear lines are provided at positions away from the notches, the tear lines are not torn and the light-shielding effect does not deteriorate.

[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 composed of an upper portion of a V-shaped notch 6 formed between two points located slightly below the upper edge portion 5 of the opening of the outer bag, and an adhesive agent is applied to the back surface thereof. There is. In the case of this example, the two starting points for forming the V-shaped notch 6 are provided at a distance of 1.5 cm, which is 2 mm below the upper edge of the opening of the outer bag.

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 agent 7 with a drain port 8 left. The inner bag 3 is formed of white or light-colored paraffin wax paper or a resin film in a tubular shape.

Further, 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 a vertical fold 9 on its side surface.

In practice, after forming a notch and a tear line on the outer bag in the expanded state, an adhesive is applied at a predetermined position and the outer bag is folded to form the bag, and at the same time, the adhesive piece and the inner bag are separated. The process of adhering is automatically and continuously performed. Therefore, in the case of the double-fruit bag according to the present invention, the flaking of the adhesive piece is less than that shown in FIG. 4, so that poor adhesion to the inner bag is unlikely to occur.

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 is enlarged after a certain period of time, the tearing 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.

FIG. 3 is a perspective view showing an embodiment of a double fruit bag according to the invention of claim 2, above the V-shaped notch 6 described above and above the opening upper edge 5 of the outer bag. The projecting triangular-shaped protruding piece 14 is provided. A notch 15 is formed at the lower edge of the outer bag so as to face the protruding piece.

Further, the relationship between the protrusion 14 and the notch can be selected as appropriate. That is, it is possible to make the distance between two points, which is the starting point of the V-shaped notch 6, larger than the root width of the projecting piece, or conversely, smaller than the root width of the projecting piece. In any case, the uncut portion 16 formed between the starting point of the notch 6 and the upper edge of the opening of the outer bag or the edge of the protruding piece is set to about 1 to 3 mm. It is desirable to do.

[0024]

[Effect of device]
