DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape material for preventing invasion of gastropods used for protecting plants and the like from gastropods such as slugs, and more particularly to a tape material which is disposed so as to cross a path through which gastropods pass. The present invention relates to a tape material for preventing gastropod invasion, which is used to prevent gastropods from intruding beyond it by utilizing the repelling property.

[0002]

BACKGROUND OF THE INVENTION Gastropods such as slugs and snails damage plants. For example, if such damage is caused to fruits such as oranges, the commercial value of the fruits is significantly reduced, which is a serious problem for fruit farmers. Various measures have been taken.

As a conventional countermeasure that is of interest to the present invention, there is a method of keeping slugs and the like away from fruits by utilizing the fact that gastropods such as slugs have a property of repelling copper. For example, Japanese Patent Application Laid-Open No. Hei 2-9806 proposes that a tape material made of copper, for example, a tape material for preventing gastropod invasion, be wound around a trunk of a fruit tree such as oranges. According to this method, slugs and the like that try to crawl along the trunk from the ground do not approach the tape material made of copper, and thus can be prevented from reaching the fruit through the tape material.

[0004]

In order to prevent slugs and the like from crawling along the trunk by the above-mentioned tape material made of copper, the tape material is brought into contact with or as close as possible to the surface of the trunk over the entire circumference. It is important to wrap in a folded state. Because, when a gap is formed between the tape material and the surface of the trunk that allows slugs to pass therethrough, the slugs and the like can pass over the tape material through this gap without touching the tape material. Because you can.

On the other hand, for example, when the trunk of a fruit tree such as tangerine has a circular cross section, for example, only a convex surface is formed on its surface and no concave surface is formed. It is relatively easy to wind in contact or close proximity to the surface of the trunk. However, it is rather rare that the surface of the trunk of a fruit tree such as a tangerine forms only a convex surface, and it often forms a concave surface in part.

[0006] As described above, if the surface of the trunk forms a concave surface in part, simply wrapping the tape material around such a trunk will bring the tape material into contact with or close to the surface of the trunk over the entire circumference. I can't let that happen. In order for the tape material to be in contact or close proximity over the entire circumference of the trunk, the tape material must be appropriately deformed to conform to the concave surface of the trunk. However, since the state of formation of the concave surface differs depending on the trunk, an operation for deforming the tape material so as to conform to each trunk becomes extremely complicated. Even if the tape material is deformed along the concave surface of the trunk, it may be difficult to properly contact or approach the tape material to the concave surface depending on the state of the concave surface.

An object of the present invention is to provide a gastropod intrusion prevention tape material which can solve the above-mentioned problems.

[0008]

SUMMARY OF THE INVENTION The present invention is used to prevent gastropods from invading beyond the path of gastropods, which are arranged so as to traverse the path through which the gastropods pass. The present invention is directed to a gastropod intrusion prevention tape material. The gastropod intrusion prevention tape material is plastically deformable, and at least the surface is made of a metal material containing copper. And in order to solve the above-mentioned technical problem, a plurality of cuts extending in a direction intersecting with the longitudinal direction are formed in at least one side edge of the tape material for preventing gastropod invasion,
Thereby, a plurality of tongue pieces are formed along the side edge.

[0009] The above-mentioned cut is preferably formed so as to extend in a direction perpendicular to the longitudinal direction of the tape material.

[0010]

According to the tape material for preventing gastropods from entering according to the present invention, the tape material is simply wound around the trunk, and when a concave surface is formed on the trunk, the tongue piece is brought into contact with the concave surface. If the tongue piece is appropriately bent at the concave portion, the tape material can be brought into contact with or close to the surface of the trunk over the entire circumference.
Therefore, a gap that may be formed between the tape member and the concave surface of the trunk and that allows passage of slugs or the like can be closed by the tongue pieces. Therefore, at least the surface of this tape material is made of a metal material containing copper, and since the slugs and the like have the property of repelling copper, slugs and the like crawling along the trunk cross the tape material. It can be almost completely prevented from passing.

Further, the tape material for preventing gastropod invasion according to the present invention can be plastically deformed. Therefore, when the tape material is wound around the trunk, its form is maintained, so that the work for winding is easy. is there. Similarly, since the tongue piece constituted by a part of the tape material can also be plastically deformed, the form is maintained only by bending the tongue piece as described above. Therefore, it is easy to bend the tongue piece to close the gap formed between the tape material and the concave surface of the trunk.

In the present invention, as described above, the cut is formed so as to extend in a direction not perpendicular to the longitudinal direction of the tape material, so that the tongue piece is oblique to the width direction of the tape material. When formed to extend,
Within the predetermined width dimension of the tape material, the length of the tongue piece can be made longer, and the tongue is adapted to the concave surface of the trunk so as to close the gap between the tape material and the concave surface of the trunk. Folding the pieces becomes easier.

[0013]

FIG. 1 is a plan view showing a tape material 1 for preventing gastropod invasion according to an embodiment of the present invention.
The tape material 1 is prepared in a long state.
Cut into appropriate lengths. FIG. 1 shows a long tape material 1
Are shown. In this embodiment, the tape material 1 is made of a copper plate so that it can be plastically deformed and at least the surface is made of a metal material containing copper. The larger the width of the tape material 1 in the width direction is, the more certain the effect of blocking the passage of gastropods such as slugs increases. However, in consideration of handling and economy, for example,
The size is selected from 2 cm to 5 cm, more preferably from 3 cm to 4 cm. Regarding the thickness of the copper plate used for the tape material 1,
The value is determined in consideration of the handling property and economical efficiency when wound around the trunk, but for example, 0.1 mm or less is sufficient. In addition,
In order to make plastic deformation easier, it is also effective to bake and soften the copper plate used for the tape material 1.

A plurality of cuts 2 extending in a direction crossing the longitudinal direction are formed on one side edge of the tape material 1, whereby a plurality of tongue pieces 3 are formed along the side edge. The tip portions of the tongue pieces 3 are preferably processed so that the corners are rounded as shown in the figure in order to prevent injury to the operator. Cut 2 above
Is formed so as to extend in a range of about three-fourths to about one-half the width of the tape material 1. Further, the pitch at which the notch 2 is formed, that is, the width of each tongue 3 is arbitrarily selected, but the width of each tongue 3 measured in the longitudinal direction of the tape material 1 is selected to be, for example, about 3 mm to 15 mm.

In this embodiment, the cut 2 is
The tape 1 is formed so as to extend in a non-perpendicular direction to the longitudinal direction. Thereby, the tongue piece 3 is formed so as to extend obliquely to the width direction of the tape material 1. The angle between the direction in which the notch 2 extends and the longitudinal direction of the tape material 1 is, for example, 50 to 70 degrees, preferably 6 degrees.
Selected around 0 degrees.

As described above, when the notch 2 is formed so as to extend in a direction not perpendicular to the longitudinal direction of the tape material 1, the notch 2 is formed so as to extend in a direction perpendicular to the longitudinal direction of the tape material 1. Tape material 1
Within the range of the predetermined width direction dimension, the length of the tongue piece 3 can be made longer, and as described later,
It becomes easier to bend the tongue piece 3 in conformity with the concave surface of the trunk so as to close the gap between the tape material 1 and the concave surface of the trunk. If these advantages are not desired, cut 2
May be formed so as to extend in a direction perpendicular to the longitudinal direction of the tape material 1.

FIG. 2 shows an example of a method of using the tape material 1 for preventing gastropod invasion described above. For example, the tape material 1 is wound around a trunk 5 of a fruit tree 4 such as a tangerine. It is preferable that the winding position of the tape material 1 is set at a height at which weeds that may grow on the ground 6 cannot reach. FIG.
FIG. 3 is an enlarged sectional view taken along line III-III in FIG. 2.

Referring to FIG. 3, the tape material 1 cut to a desired length is wound around the trunk 5 and the ends 7 and 8 thereof are fitted together as shown by a two-dot chain line. In this state, tension is applied to the tape material 1 so that the tape material 1 contacts the peripheral surface of the trunk 5 as closely as possible. In FIG. 3, a gap is formed between the peripheral surface of the trunk 5 and the tape material 1. However, this is illustrated by clearly distinguishing the trunk 5 from the tape material 1. In practice, the tape material 1 is made to adhere as closely as possible to the peripheral surface of the trunk 5.

Next, both ends 7 and 8 described above are bent as shown by arrows 9 so as to be in a state along the other part of the tape material 1. In this state, although the tape material 1 has its ends 7 and 8 merely overlapping and not engaged with each other, the tape material 1 made of a copper plate has a plastically deformable property and rigidity.
This winding state can be maintained simply by being wound around the base member. In this way, the tape material 1 wound around the trunk 5 simply by overlapping the both ends 7 and 8 in this way
Even if the trunk 5 becomes thicker due to growth, it can follow this while maintaining this wound state.

As shown in FIG. 3, a concave surface 10 is formed on the peripheral surface of the trunk 5. Due to the presence of the concave surface 10, a gap allowing passage of gastropods such as slugs crawling along the trunk 5 is formed between the concave surface 10 and the tape material 1 by simply winding the tape material 1 around the trunk 5. May be done. The tongue 3 is appropriately bent at the concave surface 10 so that the tip of the tongue 3 contacts the concave surface 10 so as to close the gap. At this time, the tongue piece 3 is constituted by a part of the tape material 1 and is also plastically deformable. Therefore, the form can be maintained only by bending the tongue piece 3.

In this way, the tape material 1 can be brought into contact with or close to the surface of the trunk 5 over the entire circumference, and since the tape material 1 is made of copper, which is disliked by slugs, etc. The slugs crawling along the trunk 5 can be almost completely prevented from passing over the tape material 1 in the concave portion 10 and in the portion other than the concave surface 10.

In this embodiment, the notch 2 is formed so as to extend in a direction not perpendicular to the longitudinal direction of the tape material 1, so that the tongue 3 is oblique to the width direction of the tape material 1. It is formed so as to extend. Therefore, the length of the tongue piece 3 can be made longer within the range of the predetermined width direction dimension of the tape material 1, so that the degree of freedom regarding the form of bending of the tongue piece 3 is increased, and therefore, the concave surface 10 of the trunk 5 is increased. And it is easier to bend the tongue piece 3. In addition, as shown in FIG. 3, the concave surface 10 often extends from another portion of the peripheral surface of the trunk 5 via a gentle curved surface 11, but is formed so that the tongue piece 3 extends in an oblique direction. Also, the tongue piece 3a can be brought into contact with or close to the curved surface 11 without difficulty, especially at the side edge.

FIG. 4 is a front view showing another example of a mode of winding the tape material 1 for preventing gastropod invasion around the trunk 5. Here, another example of the processing method of the overlapped end portions 7 and 8 of the tape material 1 is shown. That is, the tape material 1
After overlapping both ends 7 and 8, the tongue pieces 3b and 3c located at each of the overlapped ends 7 and 8
By bending them together, for example, outwardly.
And 8 are engaged with each other. In this way, the state of winding the tape material 1 around the trunk 5 can be more reliably maintained. Even if the tongue pieces 3b and 3c are bent in this way, a path through which slugs and the like can pass without touching the tape material 1 is not formed.

FIG. 5 shows another example of the method of using the tape material 1 for preventing gastropod invasion. Here, flower pot 1
2, the tape material 1 is wound. In the illustrated example, the position of the tape material 1 is near the bottom of the flower pot 12,
It may be near the upper end of the flowerpot 12 or at an intermediate portion in the height direction. In the case of the flowerpot 12 having a general shape, the tongue piece 3 is not particularly required because no concave surface is formed on the peripheral surface thereof. In such a case, the tongue piece 3 is not bent. You can leave it in a straight state. Although not shown, when the tape material 1 is wound along the upper end of the flowerpot 12, the tongue piece 3 may be protruded from the upper edge of the flowerpot 12 and may be bent inward so as to engage with the upper edge. .

In each of the above-described methods of use, the tape material 1 is applied to the trunk 5 or the flowerpot 12 of the fruit tree 4 such as mandarin orange. However, the tape material 1 may be applied to the trunk of a tree other than the fruit tree. Raw wood for cultivation, stems of vegetables, etc.
Etc. may be applied. Further, in each of the illustrated usage methods described above, the tape material 1 is wound with the tongue piece 3 facing upward, but the tape material 1 is wound with the tongue piece 3 facing downward.
May be wound.

In each of the illustrated methods of use, for example,
Although one tape material 1 is wound around one stem 5 or one flowerpot 12, a plurality of tape materials 1 may be wound in parallel in multiple stages. Alternatively, one long tape material 1 may be wound around a plurality of rounds. In this case, the tape material 1 may be wound at
The tape material 1 may be spirally wound.

In each of the illustrated methods of use, the tape material 1
Was wound around the trunk 5 or the flowerpot 12, for example, so as to cross the path through which the slugs and the like pass. However, when the tape material 1 is used for an application other than such a trunk or the flowerpot, the tape material 1 is wound. It may be in a state of crossing the path through which slugs and the like pass by a method other than attaching. For example, when a field or an orchard is divided by a stone wall, the tape 1 may be arranged along the stone wall because the stone wall tends to be a path through which slugs and the like pass.

In the illustrated embodiment, the tape 1
On one side edge of the tape material, a plurality of cuts 2 were formed, thereby forming a plurality of tongue pieces 3 along the one side edge, the cuts being formed on both side edges of the tape material, respectively. A tongue may be formed along each of these side edges. As in the latter case, when the tongue pieces are formed along both side edges, respectively, the formation pitch, that is, the width of the tongue pieces is different between those formed along one side edge and those formed along the other side edge. May be different from each other. When one tape material has two kinds of tongue pieces having different pitches or widths as described above,
For example, a tongue piece having a more appropriate pitch or width can be used depending on the state of the concave surface formed on the surface of the trunk on which the tape material is to be wound.

In the illustrated embodiment, the tape 1
Is made of a copper plate, but is not necessarily made of a copper plate, and may be made of, for example, a plate made of a copper alloy. That is, the tape material 1 may be constituted by a plate made of a metal material containing copper. Further, it is not always necessary that the tape material 1 is entirely formed of a plate made of a metal material containing copper. That is, it is sufficient that at least the surface of the tape material 1 is made of a metal material containing copper. For example, the tape material 1 is made of a metal such as aluminum or iron, or a non-metal material such as a resin. A film or foil made of a metal material containing copper may have a composite structure formed by a method such as plating or sticking. Note that the plastically deformable property of the tape material 1 is given by the plastically deformable property of the metal plate itself when the tape material 1 is made of a metal plate. When the tape material 1 has a composite structure, it is given by the plastically deformable property of any component of the composite structure.
