Description

[Technical Field]

[0001] The present invention relates to a bagging method for fruit trees, a bagging method for fruit trees, and a bagging method for fruit trees used in the method. [Background technology]

[0002] In fruit cultivation, if fruit is left to ripen after bearing fruit, it often rots for various reasons. This phenomenon is particularly noticeable in soft fruit trees such as figs. Most of the rot is caused by fungi transmitted by insects or underground fungi that splash up in the rain and attach to the leaves. To prevent this from happening, disinfection and bagging are carried out, but disinfection involves the use of pesticides, which causes some resistance from consumers.

[0003] In consideration of the above circumstances, it is common practice to bag fruit trees during their growing stage. There are various types of fruit bag used in this way, and prior art that aims to prevent damage by insects and other pests in relation to the present invention can be found in patent and non-patent literature.

[0004] Fruit bags with enclosed or retained fasteners are found, for example, in Japanese Utility Model Application Laid-Open Publication Nos. 57-158343 and 47-13314 (Patent Documents 1 and 2). In other words, the opening of the bag is fastened around the fruit stalk with enclosed or retained fasteners.

[0005] Patent document 3 (Japanese Utility Model Application Laid-Open Publication No. 03-65448) discloses a fruit bag in which closing strings (9) are threaded through cylindrical portions (2) for attaching the closing strings provided at the upper ends of the front and rear walls (3) and (4) of the cover body (1). A similar structure is also disclosed in patent document 4 (Chinese Utility Model Registration No. 203152153).

[0006] The above-mentioned Patent Documents 3 and 4 have a configuration in which two strings are pulled from both sides to close the opening, but Patent Document 5 (JP Patent Publication No. 2018-183071) discloses a configuration in which a single string is used, and states that the string may be made of wire (paragraph 0026). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Utility Model Application Publication No. 57-158343 [Patent Document 2] Japanese Utility Model Application Publication No. 47-13314 [Patent Document 3] Japanese Utility Model Application Publication No. 03-65448 [Patent Document 4] China Utility Model Registration No. 203152153 [Patent Document 5] Japanese Patent Application Publication No. 2018-183071 Summary of the Invention [Problem to be solved by the invention]

[0008] The structure of closing the opening of the fruit bag using a fastener piece sealed or held in the fruit bag (Patent Document 1 or 2) has the disadvantage that the operation requires the use of the fingertips of both hands.

[0009] The procedure for this is to first open the opening of the bag and place it over the fruit tree, then narrow the opening by squeezing both sides together. While holding the narrowed opening with the fingertips of one hand, the fingertips of the other hand place the clasp attached to the bag over the narrowed opening and wrap the clasp around the opening to close it.

[0010] The opening may be tightened at the fruit stalk or on the branch, but in either case, the work involves holding the opening with the fingertips of one hand while wrapping the fastener around the opening with the fingertips of the other hand.

[0011] When using the stopper at the fruit stalk, you have to move your fingers between the fruit tree and the branch to turn the stopper multiple times around the fruit stalk. However, depending on the fruit species, the fruit stalk is only about 1 cm long, and in short fruit species it can be less than 5 mm. Working with your fingertips in such a narrow space can be tedious.

[0012] The configurations disclosed in Patent Documents 3 and 4, in which the opening is tightened by pulling the strings, are much easier than those disclosed in Patent Documents 1 and 2, if all you have to do is "pull the strings." However, if the strings are left in a pulled state, the strings will loosen due to wind, etc., and the sealing of the opening will no longer be maintained. Therefore, as shown in Figure 3 of Patent Document 3 (Figure 9 of the present application), it is necessary to form a "knot" with the two pulled strings under or above the branch.

[0013] However, to form a knot, a cumbersome process is required, in which a knotting hole is made in one string and the tip of the other string is passed through the knotting hole.

[0014] The fruit bags are exposed to the elements for long periods of time, so the knots become tightly tied, and the more they are exposed to the elements, the tighter they become. Untying the knots requires the use of both hands.

[0015] In addition, Patent Document 3 describes a bag with perforations (10) along its width to make it easier to tear the bag when harvesting. This means that when two strings are used, the opening cannot be easily opened by simply pulling from both sides.

[0016] The reason for this is that, as mentioned above, the knot is tightly tied so that it can withstand wind and rain for a long period of time, and if a long time (more than a month depending on the fruit species) has passed since it was formed and it is exposed to wind and rain during that time, the knot becomes even harder, and it takes a long time to untie it with the fingertips of both hands, or it becomes so tight that it cannot be untied.

[0017] In addition, in order to untie the "knot," it is necessary to use the fingertips of both hands, and even if the "knot" is untie, the friction between the hole through which the string passes and the string becomes large, creating a state in which the opening does not open easily even when a large force is applied.

[0018] In the above Patent Documents 1 and 2, and Patent Documents 3 and 4, each task is not particularly time-consuming, but if it is necessary to bag 1,000 or 2,000 items per day, it takes an enormous amount of time, which hinders work efficiency.

[0019] Patent Document 5 discloses a configuration in which a single string (wire) is used to tighten the opening. With this configuration, the fingertips of one hand are used to hold the string near the fruit stalk, while the fingers of the other hand are used to pull the end of the string. Because there is only one string, the opening easily loosens, and not only is it difficult to maintain a tight seal, but it is also cumbersome to have to hold the fingertips of the hand near the fruit stalk when the branches and leaves are thick.

[0020] In addition, the end of the string is tied to the branch, but this task also requires the use of fingertips, which takes time, and there is also the drawback that fastening to the branch using a single string (wire) is prone to loosening.

[0021] The present invention has been proposed in view of the above-mentioned conventional circumstances, and proposes a bagging and unbagging method that eliminates all fingertip work, as well as a fruit bag for use in this method. [Means for solving the problem]

[0022] The fruit bag used in the present invention has the following outer bag, front and back through holes, and sealing unit.

[0023] The outer bag is made of a transparent or semi-transparent sheet of synthetic resin.

[0024] The through holes on the front and back are formed by cutting a predetermined depth into the upper end of the side edge at both ends of the opening of the outer bag, folding back the opening, and welding the ends to the bag body.

[0025] Furthermore, the sealing unit comprises a first sealing device in which a first metal wire is folded in half and one tip is inserted into one of the front through holes and the other tip into one of the rear through holes, with the two tips protruding from the other side of each through hole; and a second sealing device in which a second metal wire is folded in half and one tip is inserted into the other of the front through holes and the other tip into the other of the rear through holes, with the two tips protruding from one side of each through hole.

[0026] The opening of the fruit bag of the above configuration is opened, young fruit is placed inside the outer bag, the opening is closed by pulling the first metal wire and the second metal wire outward relative to each other, and the opening is sealed by folding the first metal wire and the second metal wire inward.

[0027] The sealing can be further ensured by twisting the folded first and second metal wires together, which can prevent the fruit from falling on branches with young fruit.

[0028] The seal can be easily removed by pulling on both ends of the opening (after untwisting, if any). [Effects of the Invention]

[0029] The opening of the outer bag can be sealed at the fruit stalk simply by pulling the first and second metal pieces from both sides and folding them back, eliminating the need to use the fingers of both hands and making the bagging process extremely easy.Furthermore, since there is no gap between the opening and the fruit stalk, pests and rainwater will not get in through this area.

[0030] Furthermore, because the sealed outer bag can be opened simply by pulling the top edge, both the bagging and unbagging processes take less than a few seconds, significantly improving cost performance. Furthermore, because the bag itself is not damaged, the same fruit bag can be reused the following year or even the year after, resulting in even greater cost performance.

[Figure 9] FIG. 1 is a diagram showing the installation state of a conventional fruit bag. DETAILED DESCRIPTION OF THE INVENTION

[0032] The most tedious and time-consuming task of bagging and unbagging fruit trees is the need to use the fingertips of both hands. As will be explained below, the method of the present invention allows bagging and unbagging to be performed without using the fingertips of both hands.

[0033] FIG. 1 shows a fruit bag used in the present invention.

[0034] A non-water-retentive mesh lining 2 is inserted inside a transparent or semi-transparent outer bag 1 made of synthetic resin such as vinyl or nylon, and further, a sealing unit 30 is provided to seal an opening 12 at the top end of the outer bag.

[0035] <Outer bag> The outer bag 1 must be strong (thick) enough to prevent holes from being made by gnawed at by pests such as thrips, but if it is too thick, it will be impossible to seal the opening, as described below, so its thickness must be within the range of 0.03 to 0.06 mm. This thickness is based on polyethylene, but is roughly the same for other resins.

[0036] The upper edge 11a of the outer bag 1 forms an opening 12, and the left and right side edges 11b, 11c and the lower edge 11d of the outer bag 1 are sealed. In addition, multiple drainage slits 16 are formed on the outer periphery of the outer bag 1. The slits 16 are simply narrow cuts made with scissors to a predetermined depth and a predetermined length (for example, about 1 cm) inward. Because they are narrow, they prevent pests such as thrips from entering but allow moisture to escape from the inside.

[0037] <Sealing unit> (Form 1) Corresponding to the opening 12 at the top edge of the outer bag 1, a sealing unit 30 consisting of a first sealing tool and a second sealing tool is constructed as will be described below.

[0038] That is, as shown in Figure 2(a), the upper ends of the side edges 11b, 11c at both the left and right ends of the opening 12 are cut to a predetermined depth to form hole spaces 3a, 3b where the two front and back sheets are separated, and as shown in Figure 2(b), the hole spaces 3a, 3b are folded back and the ends are welded to the bag body to form front and back through holes 32a, 32b parallel to the upper edge of the outer bag.

[0039] Next, the metal wire 33a is folded in half, and one tip is inserted into one of the front through holes 32a and the other tip into one of the back through holes 32b, causing the two tips to protrude to the other side of the through holes 32a, 32b, and the two protruding tips are twisted together to form a first sealing device (Figure 2(c)).

[0040] Similarly, the metal wire 33b is folded in half, and the two ends of the wire 33b are inserted through the other of the through holes 32a, 32b, respectively, so that they protrude to one side, and the two protruding ends are twisted together to form a second sealing device.

[0041] Specifically, iron wires coated with synthetic resin are used as the metal wires 33a and 33b, but the type of metal is not limited thereto.

[0042] As will be explained later, in the above configuration, the frictional resistance between the through holes 32a, 32b and the metal wires 33a, 33b is extremely small, so that with young fruits placed in the bag, the outer bag can be closed simply by pulling the metal wires 33a, 33b in opposite directions from both sides (see Figure 3(c)). Conversely, when it is time to harvest, the outer bag can be easily opened by pulling the opening 12 from both sides without tearing it (see Figures 5(a) → 5(b)).

[0043] Furthermore, the metal wires 33a and 33b can be easily bent and twisted, making it easy to maintain the seal and attach them to the branches (see FIG. 4).

[0044] As will be explained later, the above configuration significantly improves work efficiency during harvesting, as well as bagging and unbagging, and by washing and disinfecting the bags, they can be reused the following year or the year after that.

[0045] (Form 2) The sealing unit 30 is made up of two sealing members, as in the first embodiment, but the configurations of the sealing members are different.

[0046] That is, as shown in Figure 6(a), the hole openings 3a and 3b are folded back and the ends are welded to the bag body, and front and back through holes 32a and 32b parallel to the upper end edge 11a of the outer bag are formed, which is the same as form 1 (Figure 2(a) → Figure 2(b)).

[0047] A third metal wire 33c is inserted through one of the front and rear through holes 32a and both ends are twisted outside the through hole 32a to form a third sealing device. A fourth metal wire 33d is inserted through the other of the front and rear through holes 32b and both ends are twisted outside the through hole to form a fourth sealing device (FIG. 6(b) → FIG. 6(c)).

[0048] As in the first embodiment, iron wires coated with synthetic resin are used as the metal wires 33c and 33d.

[0049] As will be explained in detail later, some fruit species, such as peaches, have extremely short stalks. When the above-mentioned form 1 is used, the shrunken material of the outer bag that constitutes the metal wires 33a, 33b and the through-holes 32a, 32b becomes interposed between the branch B and the fruit tree A, damaging the fruit tree. However, when the above-mentioned form 2 is used, only the outer bag 1 can be interposed between the branch B and the fruit tree A, eliminating the risk of damaging the fruit tree (see Figure 7(c) → Figure 8(a)).

[0050] <Interior> The lining 2 is permeable and non-water-retentive, and specifically, a mesh made of synthetic resin is used.

[0051] <Usage Instructions> (Fruit bags using sealing unit of type 1) The procedure for using the fruit bag using the sealing unit 30 of the first embodiment will be described below with reference to Figures 3, 4, and 5. The length of the pedicel B connecting the young fruit A to the branch B varies depending on the fruit species. In figs, the pedicel B is an extension of the fruit tree and is thinner than the fruit tree. In peaches, the pedicel is only a few millimeters long at most.

[0052] First, it is preferable to disinfect and sterilize young fruit A (approximately 10 to 30 mm in diameter), but this is not essential.

[0053] Next, the opening 12 of the outer bag 1 is opened, and the young fruit is inserted into the outer bag 1 through the opened opening 12 (FIG. 3a → FIG. 3b).

[0054] Next, by pulling the tips of the metal wires 33a and 33b from both sides, the fruit stalk C and the opening 12 of the outer bag 1 are sealed (Fig. 3b → Fig. 3c). In a stationary environment (indoors, in a greenhouse), the opening of the outer bag 1 will not loosen even if left in this state for a long time, but in an environment exposed to wind and rain, the seal on the opening 12 will gradually loosen. On the other hand, the iron wire at the core of the metal wire, which is covered with synthetic resin, can be bent and stretched freely.

[0055] Therefore, as shown in Figure 4(a), by folding both ends of the metal wires 33a and 33b inward, the sealing state of the opening 12 can be easily maintained. Furthermore, as shown in Figure 4(b), by twisting the metal wires 33a and 33b two or three times, the sealing can be made even more secure. By wrapping the metal wires 33a and 33b around the branch with the fruit stalk and forming the twist, the sealing state of the outer bag 1 can be maintained and the fruit can be prevented from falling even when the wind blows. The type of fruit tree to be selected can be determined by the type of fruit tree.

[0056] 3(c) is a state in which the tips of the metal wires 33a and 33b are held with the fingertips (simply holding them, no work is being done with the fingertips), and to move from this state to the state in Fig. 4(a), it is sufficient to cross the arms while still holding the tips of the metal wires 33a and 33b. In other words, there is no need to move the fingertips of both hands to do any work.

[0057] To move from the stage in Fig. 4(a) (where the tips of the metal wires 33a and 33b are held with the fingertips) to the stage in Fig. 4(b), the worker turns his arm halfway around while shifting the grip of the tips of the metal wires 33a and 33b with his fingertips. Here, there is no need to move the fingertips of both hands to form the twist in the metal wires 33a and 33b in Fig. 4(b).

[0058] Conceptually, it is possible to twist the metal wires 33a and 33b together using the fingertips of one hand in the state shown in Figure 4(a). Even if this method is used to form the twist shown in Figure 4(b), it is sufficient to use the fingertips of one hand (in reality, a twist that can withstand long-term use cannot be formed unless both arms are used).

[0059] In this way, the young fruit A covered in the fruit bag grows over time, and when it becomes ripe, it is harvested.

[0060] The most efficient way to harvest is to separate the fruit from the branch with the bag still attached, and then remove the bag. Of course, you can also remove the bag before separating the fruit from the branch.

[0061] In any case, to remove the fruit bag from the fruit tree, hold both ends of the opening 12 of the outer bag 1 and pull gently, and since the resistance between the metal wire and the outer bag 1 is small, the opening 12 can be opened with little force (see Figure 5(a) → (b)).

[0062] The twist shown in Figure 4(b) can be easily undone by holding the ends of the metal wires 33a and 33b with your fingertips and rotating your arm in the opposite direction of the twist. After that, as before, you can open the opening 12 of the outer bag 1 by holding both ends of the opening 12 and gently pulling. Therefore, in this case too, there is no need to move the fingertips of both hands.

[0063] Although the above describes an example of bagging young fruit, similar effects can be obtained by disinfecting the fruit trees with electrolyzed ionized water or an appropriate disinfectant after the fruit has ripened, and then bagging the fruit, as in the past.

[0064] This reduces bagging and unbagging to just a few seconds each, significantly improving cost performance. Furthermore, because the bag itself is not damaged, the same fruit bag can be reused the following year or even the year after, resulting in significant cost performance.

[0065] (Fruit bags using sealing unit of type 2) The procedure for using the fruit bag using the sealing unit 30 of the second embodiment will be described below with reference to Figures 7 and 8. The fruit bag using the sealing unit 30 of the second embodiment is applied to fruit trees in which the length of the fruit stalk B connecting the fruit tree A and the branch B is extremely short (for example, peaches, usually about 2 mm).

[0066] The opening 12 of the outer bag 1 is left open, and the young fruit is inserted into the outer bag 1 through the opened opening 12 (Fig. 7a → Fig. 7b). At this time, the two through holes 32a and 32b on the front and back should be parallel to the direction in which the branch B extends.

[0067] Next, while pulling the tips of the metal wires 33c and 33d and rotating your arm, twist the metal wires 33c and 33d, which closes the front and back openings of the bag and also twists the metal wires 33c and 33d together, sealing the bag, as shown in Figure 8(a) → Figure 8(b). Of course, as shown in Figure 7c, you can also pull the tips of the metal wires 33c and 33d to close the openings first, and then twist the metal wires 33c and 33d.

[0068] This operation is also performed by rotating the arm while holding the tips of the metal wires 33c and 33d with the fingers, and no fingertip work is performed during the process from FIG. 7(a) to FIG. 8(b).

[0069] As a result, even when the young fruits grow, the metal wires 33c, 33d and the shrunken portions of the material of the outer bag 1 at the through-holes 32a, 32b will not get in between the fruit tree and the branch B, allowing the fruit tree to grow without being damaged. At this time, the through-holes 32a and 32b will cover the branch B, so the opening 12 will be sealed above the branch B, preventing the intrusion of rainwater and pests. In this example, it is desirable to leave a large hole allowance in order to ensure sufficient overlap between the through-holes 32a, 32b above the branch B.

[0070] <Comparison with conventional methods> (When using the sealing unit of type 1) When bagging using Patent Document 3 or Patent Document 4, the final state is as shown in Figure 3 of Patent Document 3 (Figure 9 of the present application). That is, the string 9 is either tied below the branch on which the fruit is attached (solid line), or tied above the branch (phantom line) to prevent fruit from falling. As explained in the Problems section, tying the string involves making a hole with one string and passing the tip of the other string through the hole, which is done with the fingertips.

[0071] The bagging procedure of the present invention is compared with the procedures for bagging fruit bags according to Patent Documents 3 and 4, which were created by the applicant. The process from pulling the metal wire (string) to closing the opening takes about two seconds, which is the same for both. However, the subsequent procedure in the present invention simply involves folding back the metal wire, which takes just one second (a total of three seconds). Even if the folded back metal wires 33a and 33b are twisted, two seconds (a total of four seconds) is sufficient. Tying the knot using the methods described in Patent Documents 3 and 4 required five seconds (a total of seven seconds).

[0072] The time difference required for the bag removal procedure is even more pronounced. In the procedure of the present invention, the bag can be removed from the fruit tree in two seconds, simply by pulling the opening in both directions. However, in Patent Documents 3 and 4, it takes seven seconds because it is time-consuming to use your fingertips to untie the knot. When the "twist" described above is formed, the opening must be pulled in both directions after the "twist" is undone, but even in this case, it only takes about four seconds.

[0073] The period between bagging and unbagging varies depending on the fruit species, but fruit bags are generally exposed to wind and rain during this time. When the string-tied fruit bags of Patent Documents 3 and 4 are exposed to wind and rain, the knots harden and often cannot be opened without applying a great deal of force. For this reason, Patent Document 3 provides perforations (10) to allow the bag to be torn at harvest time, but this type of consideration is completely unnecessary in the present application. Furthermore, because the bag is not cut, the same bag can be used the following year.

[0074] In the above Patent Documents 1 and 2, the opening of the fruit bag is closed, and while maintaining this state with the fingertips of one hand, the clasp is wound around the closed opening on the fruit stalk or branch with the fingertips of the other hand. Based on the experience of the applicant, who is an experienced worker and who works with commercially available products every year, this process takes at least several seconds, and the same amount of time is required for removing the bag.

[0075] In orchards, etc., it is sometimes necessary to bag and unbag thousands or even tens of thousands of fruit, and the time difference mentioned above significantly improves work efficiency. The reason for this is whether or not you use your fingertips.

[0076] (When using the sealing unit of type 2) The fruit bag using the sealing unit of form 2 is folded back onto a fruit with a short stalk (e.g., a peach). The opening 12 is opened, and the metal wires 33c and 33d are twisted while pulling the tips of the wires and rotating the arm. This requires no fingertip work and takes about three seconds.

[0077] The opening can be closed on a branch using the techniques disclosed in Patent Documents 1 and 2, but in this case, the operation requires the use of fingertips, and even an experienced person would need several seconds or more to close the opening. [Explanation of symbols]
