Description

[Technical field]

[0001] The present invention relates to a method for bagging fruit trees, a method for removing bags, and fruit tree bags used in said methods. [Background technology]

[0002] In fruit cultivation, if fruit is left alone after it has borne fruit, it will often rot for various reasons. This phenomenon is particularly noticeable in soft fruit such as figs. Most of the rot is caused by bacteria transmitted by insects or bacteria in the ground 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, and consumers are somewhat resistant to this.

[0003] Considering the above circumstances, it is common to bag fruit trees during their growth. There are various types of fruit bags used here, and prior art for preventing insect damage in relation to the present invention can be found in patent and non-patent literature.

[0004] Fruit bags with metal fasteners sealed or held in them are found, for example, in Japanese Utility Model Application Publication No. 57-158343 and Japanese Utility Model Application Publication No. 47-13314 (Patent Documents 1 and 2). In other words, the opening of the fruit bag is fastened around the stalk by the metal fasteners sealed or held in place.

[0005] Patent document 3 (Japanese Utility Model Application Publication No. 03-65448) discloses a fruit bag in which a closing string (9) is passed through a tubular part (2) for attaching the closing string provided at the upper end of the front and rear walls (3) and (4) of the cover body (1). A similar structure is also disclosed in Patent document 4 (China 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 2018-183071 A) 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] JP 2018-183071 A Summary of the Invention [Problem to be solved by the invention]

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

[0009] In this case, the procedure is as follows: 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 state with the fingertips of one hand, the fingertips of the other hand place a clasp attached to the bag over the narrowed opening and wrap the clasp around the opening to tighten it.

[0010] The opening may be tightened at the stalk or on the branch, but in either case, the opening is held down with the fingertips of one hand while the fingertips of the other hand are used to wrap the fastener around the opening.

[0011] When using the stopper at the fruit stalk, it is necessary to move your fingers between the fruit tree and the branch to turn the stopper around the fruit stalk several times. However, depending on the fruit species, the fruit stalk is at most 1 cm long, and for short fruit species, it may be less than 5 mm. Working with your fingertips in such a narrow space is troublesome.

[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 that is required is "pulling 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 disclosed 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, in order to form a "knot," a cumbersome task is required, which is to make a knotting hole in one string and then pass the tip of the other string through the knotting hole.

[0014] Since fruit bags are exposed to the elements for long periods of time, the knots become tightly tied, and the more the bag is exposed to the elements, the tighter it gets. To untie the knots, the fingertips of both hands are required.

[0015] In addition, in Patent Document 3, perforations (10) are provided along the width of the bag to make it easier to tear the bag apart during harvesting. This means that when two strings are used, the opening cannot be easily opened by just pulling from both sides.

[0016] The reason for this is that, as mentioned above, the "knot" is tied tightly enough to withstand wind and rain for a long time, and if a long time (more than a month depending on the fruit species) has passed since it was formed and the fruit 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," the fingertips of both hands are required, and even if the "knot" is undone, the friction between the hole through which the string passes and the string becomes large, creating a state in which the opening cannot be easily opened even when a large force is applied.

[0018] In the above-mentioned Patent Documents 1 and 2, and Patent Documents 3 and 4, each individual task is not particularly time-consuming, but when it is necessary to bag 1,000 or 2,000 items per day, it takes an enormous amount of time, which impedes 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 hold the string near the fruit stalk, and the fingers of the other hand pull the end of the string. Since there is only one string, the opening loosens easily, and not only is it impossible to maintain the seal, but it is also cumbersome to have to hold the fingertips near the fruit stalk when it is covered with branches and leaves.

[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 coming loose.

[0021] The present invention has been proposed in consideration of the above-mentioned conventional circumstances, and proposes a bagging and unbagging method that eliminates any finger work, and further proposes a fruit bag for use in said 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 portions of the sides of both ends of the opening of the outer bag, folding back the opening portions, 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 is inserted into one of the rear through holes so that the two tips protrude 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 side of the front through hole and the other tip is inserted into the other side of the rear through hole so that the two tips protrude from one side of each through hole.

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

[0027] The sealing can be made more secure by crossing the folded first and second metal wires and twisting them together. On branches with young fruit, the twisting can prevent the fruit from falling off.

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

[0029] The opening of the outer bag can be sealed at the fruit stalk simply by pulling the first and second metals 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, there is absolutely no chance of insects or rainwater getting in through this area.

[0030] Furthermore, since the bag can be opened by simply pulling the top end of the sealed outer bag, the bagging and unbagging operations each take less than a few seconds, significantly improving cost performance. Also, since the bag is not damaged, the fruit bag can be used the following year or the year after, resulting in even greater cost performance. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The most tedious and time-consuming part of bagging and unbagging fruit is the use of the fingertips of both hands. The method of the present invention, as described below, allows bagging and unbagging to be done without using the fingertips of both hands at all.

[0033] FIG. 1 shows a fruit bag for use 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 a synthetic resin such as vinyl or nylon, and further, a sealing unit 30 is provided to seal an opening 12 at the upper end of the outer bag.

[0035] <Outer bag> The outer bag 1 must be strong enough (thick enough) to prevent thrips and other pests from gnawing at it and creating holes in it, but if it is too thick it will be impossible to seal the opening, which will be described later, so the 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, a plurality of water drainage slits 16 are formed on the outer periphery of the outer bag 1. The slits 16 are simply narrow cuts made with a pair of scissors to a given depth and a given length (for example, about 1 cm) inward, and because they have no width, they do not allow pests such as thrips to enter but allow moisture to escape from the inside.

[0037] <Sealing unit> (Form 1) Corresponding to the opening 12 at the upper end side of the outer bag 1, a sealing unit 30 consisting of a first sealing tool and a second sealing tool is configured as described below.

[0038] That is, as shown in FIG. 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 in which the two front and back sheets are separated, and as shown in FIG. 2(b), the hole spaces 3a, 3b are folded back and the tips 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, one end is inserted into one of the front through holes 32a and the other end is inserted into one of the rear through holes 32b, and the two ends are made to protrude to the other sides of the through holes 32a, 32b, and the two protruding ends are twisted together to form a first sealant (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 as to protrude to one side, and the two ends on the protruding side are twisted together to form a second sealing device.

[0041] Specifically, iron wires covered 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 described 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 in the bag, the outer bag can be closed simply by pulling the metal wires 33a, 33b in opposite directions from both sides (see FIG. 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 FIG. 5(a)→FIG. 5(b)).

[0043] Additionally, the metal wires 33a, 33b can be easily bent or twisted, allowing for easy maintenance of the seal and attachment to the branch (see FIG. 4).

[0044] As will be explained later, the above-mentioned configuration significantly improves the efficiency of bagging and unbagging operations as well as the work efficiency during harvesting, 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 composed 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, 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 end edge 11a of the outer bag, which is the same as form 1 (Figure 2(a) → Figure 2(b)).

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

[0048] As in the first embodiment, iron wires covered 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. If 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 will be interposed between the branch B and the fruit tree A, damaging the fruit tree. However, if the above-mentioned form 2 is used, only the outer bag 1 can be formed to be interposed between the branch B and the fruit tree A, so there is no need to worry about damaging the fruit tree (see Fig. 7(c) → Fig. 8(a)).

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

[0051] <How to use> (Fruit bags using sealing unit of type 1) The procedure for using the fruit bag using the sealing unit 30 of the above-mentioned form 1 will be described below with reference to Figures 3, 4, and 5. The length of the fruit stalk B connecting the young fruit A and the branch B varies depending on the fruit species. In the case of figs, the stalk B is an extension of the fruit tree and has a thinner part than the fruit tree. In addition, in the case of peaches, the stalk B is only a few mm 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 open opening 12 (FIG. 3a→FIG. 3b).

[0054] Next, by pulling the tips of the metal wires 33a, 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 it is left in this state for a long time, but in an environment exposed to wind and rain, the sealing state of the opening 12 will gradually loosen. On the other hand, the iron wire that is the core of the metal wire covered with synthetic resin can be bent and stretched freely.

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

[0056] Here, in the stage of Fig. 3(c), the tips of the metal wires 33a and 33b are held by the fingertips (simply holding them, no work is being done with the fingertips), and to move from this stage to the state of 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 by the fingertips) to the stage in Fig. 4(b), the arm is turned half a circle while the tips of the metal wires 33a and 33b are held by the fingertips. Here, there is no need to move the fingertips of both hands to form the twist of 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 Fig. 4(a). Even if this method is used to form the twist shown in Fig. 4(b), the fingertips of one hand are sufficient (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 cut the tree from the branch with the bag still attached and then remove the bag. Of course, you can also remove the bag before cutting the tree from the branch.

[0061] In any case, to remove the fruit bag from the tree, hold both ends of the opening 12 of the outer bag 1 and pull lightly. 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 Fig. 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 to the twist. After that, just like before, hold both ends of the opening 12 of the outer bag 1 and pull lightly to open the opening 12. 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 the young fruit, the same effect can be obtained by bagging the fruit trees after they have ripened, disinfecting them with electrolytic water or an appropriate disinfectant, as before.

[0064] This reduces bagging and unbagging to just a few seconds each, significantly improving cost performance. In addition, because the bag is not damaged, the fruit bag can be used the following year or the year after, resulting in great 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 above-mentioned form 2 will be described below with reference to Figures 7 and 8. The fruit bag using the sealing unit 30 of the above-mentioned form 2 is applied to fruit trees in which the length of the fruit stalk B connecting the fruit 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 open opening 12 (Fig. 7a → Fig. 7b). At this time, the two through holes 32a and 32b on the front and back are made parallel to the direction in which the branch B extends.

[0067] Next, while pulling the tips of the metal wires 33c and 33d and twisting the wires 33c and 33d while rotating the arm, the openings on the front and back of the bag close and the metal wires 33c and 33d twist each other to seal the bag, as shown in Fig. 8(a) → Fig. 8(b). Of course, the tips of the metal wires 33c and 33d may be pulled to close the openings, and then the metal wires 33c and 33d may be twisted, as shown in Fig. 7c.

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

[0069] As a result, even if the young fruits grow, the metal wires 33c, 33d and the shrunken parts of the material of the outer bag 1 at the through holes 32a, 32b do 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 cover the branch B, so the opening 12 is 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 and 32b on the branch B.

[0070] <Comparison with conventional methods> (When using the sealing unit of type 1) When bagging is performed using Patent Document 3 or Patent Document 4, the final state is as shown in Fig. 3 of Patent Document 3 (Fig. 9 of the present application). That is, the string 9 is either tied under the branch with the fruit (solid line) or tied above the branch (imaginary line) taking into consideration fallen fruit. 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, and this operation is performed with the fingertips.

[0071] The time required for 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. It takes about 2 seconds for both to pull the metal wire (string) and close the opening. However, the procedure thereafter in the present invention simply involves folding back the metal wire, so it takes only 1 second (3 seconds in total). Even if the folded back metal wires 33a and 33b are twisted, it takes only 2 seconds (4 seconds in total). It took 5 seconds (7 seconds in total) to tie the knot using the methods described in Patent Documents 3 and 4.

[0072] The time difference required for the bag removal procedure is more noticeable. In the procedure of the present invention, the opening is simply pulled in both directions, so the bag can be removed from the tree in 2 seconds. However, in Patent Documents 3 and 4, it takes 7 seconds because it is time-consuming to use your fingertips to untie the knot. If the above-mentioned "twist" is formed, the opening must be pulled in both directions after the "twist" is undone, but even in this case, it only takes about 4 seconds.

[0073] The period from bagging to unbagging varies depending on the fruit species, but in general the fruit bags are exposed to wind and rain during this time. When the fruit bags of Patent Documents 3 and 4 are exposed to wind and rain while tied with string, the knots become hard and often cannot be opened without applying a large amount of force even if one tries to untie them. For this reason, Patent Document 3 provides perforations (10) so that the bag can be torn at the time of harvesting, but this kind of consideration is not necessary at all in the present application. Also, since the bag is not cut, the same bag can be used the following year.

[0074] In the above-mentioned 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 fingertips of the other hand are used to wrap the clasp around the opening in the closed state on the fruit stalk or branch. Based on the experience of the applicant, who is an experienced worker, who works with commercially available products every year, it is estimated that this requires at least several seconds, and the bag removal work also requires a similar amount of time.

[0075] In orchards, etc., sometimes thousands or even tens of thousands of fruit need to be bagged and unbagged, 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 on the fruit with a short stalk (e.g., peach). Here, the opening 12 is opened, and the metal wires 33c and 33d are twisted while pulling the tips of the wires 33c and 33d and rotating the arms, so there is no finger work involved. The entire process takes about 3 seconds.

[0077] Although the opening can be closed on a branch using the techniques disclosed in Patent Documents 1 and 2, this requires fingertip operation, and therefore requires several seconds or more even for an experienced person. [Explanation of symbols]
