Abstract

PROBLEM TO BE SOLVED: To provide an insect-proof sheet that preferably exterminates or repels pests in fruit trees or vegetable gardens at low cost.SOLUTION: A non-permeable long sheet of a predetermined width is folded in the shape of bellows so that peaks and troughs in the width direction may continue alternately in the longitudinal direction, and thereby a bellows sheet is obtained. Also, the peaks are held down and broken lines are formed by double threads in the longitudinal direction of the bellows sheet. Adhesives are laminated over the whole length direction on one surface of a central area divided by the broken lines of the double threads. An insect-proof sheet is cut in a length corresponding to the length of a target place to thereby form sheet pieces, and is made to adhere to trunks of fruit trees and fences of vegetable gardens using the adhesives to thereby form fixing parts. In this way, the upper parts of the sheet pieces are horizontally bent by using the broken lines of the upper side of the sheet pieces fixed to the trunks and fences to thereby form umbrella parts, and the lower ends of the sheet pieces are bent in the upper direction by using the broken lines under the sheet pieces to thereby form drug parts, and then the drugs with insect killing or insect repelling effects are filled in the drug parts.

Description

  The present invention relates to an insect repellent sheet and an insect repellent using the same, and more particularly to an insect repellent sheet and an insect repellent used for fruit trees.

  Various methods have been adopted for insect control of trees, particularly fruit trees.

  Most of them are band-like bodies in which a sticky substance or a toxic drug is applied to the surface, and pests are captured or killed by winding the band-like tree. (For example, JP-A-6-217670).

  There is also a proposal of using a non-woven fabric for the band-like body and capturing pests with the fluff of the non-woven fabric (Japanese Patent Laid-Open No. 2006-262774).

  Furthermore, an umbrella-like body that prevents the insects from creeping up the tree is attached to the trunk, and a sticky substance is applied to the back of the umbrella (Japanese Patent Laid-Open No. 7-87), or an insecticide around the trunk inside the umbrella There is a configuration (JP-A-8-23864) in which an agent is disposed. In JP-A-7-87, an accordion-shaped medium is wound around a tree in an umbrella shape and its stretchability is used so as not to hinder the growth of the tree.

JP-A-6-217670 JP-A-7-87 JP-A-8-23864 JP 2006-262774 A

  A structure in which an adhesive substance or an insecticide is applied to the surface of the band-like body is naturally vulnerable to changes in weather, and long-term efficacy cannot be expected. Moreover, the structure using a nonwoven fabric is naturally accompanied by aging, and a long-term effect cannot be expected. In Japanese Patent Laid-Open No. 7-87 or Japanese Patent Laid-Open No. 8-23864, since the adhesive substance or the drug is arranged on the back side of the umbrella-like body or at the position where the umbrella-like body is violated, A longer effect can be expected than when the is exposed to the outside. In addition, in Japanese Patent Laid-Open No. 8-23864, it is possible to add an insecticide according to deterioration over time, and by selecting a flexible material, the growth of the tree is not hindered. However, the shape is complicated, and it takes time to manufacture, and there is a costly problem. In addition, since an insecticide is used, if a flexible material such as a synthetic rubber is used at a position where the insecticide comes into contact, the deterioration is accelerated, and this point is also expensive. On the other hand, Japanese Patent Application Laid-Open No. 7-87 does not inhibit the growth of trees, but it cannot prevent the adhesive from aging and needs to be replaced with a new sheet as time passes.

  Therefore, it is expected that an insect repellent sheet that can be supplemented with a pesticide (adhesive) that does not hinder tree growth and that is easy to handle and does not cost much is expected.

  The insect repellent sheet according to the present invention has the following configuration. First, a non-permeable long sheet having a predetermined width is folded into a bellows shape so that peaks and valleys in the width direction are alternately continuous in the longitudinal direction. Get a sheet. Further, two lines in the longitudinal direction of the bellows sheet are pressed down to form a broken line. A pressure-sensitive adhesive is laminated over the entire length direction on the back surface of the central region divided by the two lines.

  Thereby, it is possible to put a long object of a predetermined length around the distribution process.

  Using the insect repellent sheet, an insect repellent can be easily assembled as follows. That is, the insect repellent sheet is cut according to the length of a target portion (for example, a fruit tree trunk or a vegetable garden fence) to form a sheet piece. A part that needs insect control, for example, a wound part that is wound around a trunk of a fruit tree using the adhesive, or a fence stretched around a vegetable garden is used as a fixing part. . In this way, using the upper fold line of the sheet piece fixed to the place where insect protection is required, the upper part of the sheet piece is folded horizontally or so as to cover the drug part described below to form an umbrella part To do. Furthermore, using the fold line under the sheet piece, the lower end portion of the sheet piece is bent upward to form a drug part, and the drug part is filled with a drug having an insecticidal or insecticidal effect.

  The prototype is a long bellows-like sheet, which is cut into a length corresponding to the actual thickness of the trunk of the fruit tree on the spot or the length of the fence in the vegetable garden, and the fixed part, umbrella part and drug The part can be formed easily. Therefore, although the raw material is inexpensive, the drug is not exposed to wind and rain, and may be replenished or replaced in consideration of the aging of the drug itself. Moreover, durability can be ensured by using the material which is not violated by the medicine. Furthermore, since the pests climbing up the trees and the fence can be completely exterminated or captured, the chemical sprayed onto the fruit trees and the like can be reduced.

Perspective view of insect-proof sheet used in the present invention Side view of the insect repellent sheet viewed in the width direction Insect repellent fixed to the trunk of a fruit tree Another insect repellent fixed to the trunk of the fruit tree Insect repellent fixed to the garden fence

  FIG. 1 is a perspective view showing the appearance of an insect-proof sheet used in the present application.

  A long non-permeable material having a predetermined width, such as an aluminum sheet, is formed into a bellows sheet 1 by folding so that peaks and valleys in the width direction are alternately continuous in the longitudinal direction. This molding can be realized, for example, by winding a long aluminum sheet between two gears. Two strips 11a and 11b are formed in the longitudinal direction of the long sheet of the bellows sheet 1 thus obtained with a predetermined interval in the width direction. This broken line can be formed, for example, by pressing the bellows sheet 1 with a thin roller arranged at a predetermined interval in the width direction so as to crush the mountain. Alternatively, a long thin plate can be formed by pressing from above so as to crush the mountain. In addition, the side where the mountain was crushed becomes a valley side when the bellows sheet is folded (described later), and will be a table in the following description. By folding this surface with the valley side, it can be accurately folded along the polygonal line.

  Thereby, said bellows sheet | seat 1 will be in the state divided into 3 by the width direction by the two broken lines 11a and 11b. A region 210 from the one broken line 11a to one end in the width direction becomes an umbrella part 21 of an insect repellent described below. The umbrella portion 21 needs to have a width that covers the medicine portion 23 (described later) of the insect repellent, and the region 21 has a width of about half or more in the width direction.

  An intermediate region 220 between one broken line 11a and the other broken line 11b serves as a fixing portion 22 (described later) of the insect repellent, and a layer 221 of an adhesive material such as butyl rubber or urethane rubber is formed on the back side of the region 220. The In the distribution process, a non-adhesive protective film 222 is further laminated on the back side of the pressure-sensitive adhesive layer 221 to protect the pressure-sensitive adhesive and to prevent peripheral objects from sticking to the pressure-sensitive adhesive.

  Further, a region 230 from the other broken line 11b to the other edge in the width direction becomes a medicine part 23 (described later) of the insect repellent, and needs a width capable of filling a predetermined amount of medicine when it becomes the medicine part 23. It becomes.

  The bellows sheet 1 thus molded is used as an insect repellent as shown in FIG.

  A sheet piece 10 is formed by cutting the bellows sheet 1 in the width direction with a scissors or the like to a length that takes into account the allowance for the current thickness of the trunk 100 such as a fruit tree.

  Subsequently, the protective film 222 stretched on the back of the adhesive layer 221 is peeled off, and the sheet piece 10 is wound so that the adhesive is on the trunk side near a necessary portion of the trunk 100 of the fruit tree, for example, near the root. At this time, the direction which becomes the said umbrella part 21 is arrange | positioned up, and the direction which becomes the chemical | medical agent part 23 is arrange | positioned down. Further, an overlap margin is formed between the sheet piece 10 and the trunk 100 so that there is no gap for the ants and the like to creep up, and there is no gap between both ends. Furthermore, although the sheet piece 10 may be pulled by the force required for winding at the time of winding, since the mountain is crushed by the broken lines 11a and 11b, resistance to expansion is increased and the bellows is not collapsed.

  In this state, using the upper fold line 11a, the upper half region 210 of the sheet piece 10 is folded horizontally with the front side as a trough to form the umbrella portion 21. At this time, the circumferential length increases as the distance from the trunk 100 increases in the radial direction. However, since the sheet piece 10 has a bellows shape, changes in the circumferential length can be absorbed.

  Further, using the lower fold line 11b, the lower end region 230 of the sheet piece 10 is bent obliquely upward in a v shape with the front side as a valley. As a result, a space for storing the medicine is formed on the front side of the inner region 220 and the front side of the lower region 230, so that the medicine portion 23 can be formed. Thereafter, the drug part 23 is filled with a solid, powder, or gel drug. Moreover, even if it is a liquid chemical | medical solution, it can be set | placed on the chemical | medical agent part 23 by immersing it in moisturizing materials, such as cotton.

  FIG. 4 shows another usage pattern of the insect repellent.

  The bellows at the tip of the umbrella part 21 is stretched to cover the drug part 23 to provide sufficient protection. In addition, the tip of the drug part 23 is u-shaped to make it easier to receive the drug.

  In the insect repellent shown in FIG. 3 and FIG. 4, pests such as slugs and ants that creep up from the bottom of the trunk of the fruit tree must pass through the part of the pesticide or supplement that is placed in the drug part, It will be easily supplemented or removed. Moreover, if the umbrella part 21 is enlarged, it can make it hard to receive the influence of a wind and rain, and there is little damage to the chemical | medical agent from this viewpoint. Although the deterioration of the drug occurs with the passage of days, it is necessary to replace or replenish. At this time, the medicine is replenished by hand. When the medicine is a joll or liquid, the tip of a spoid whose tip is inverted U-shaped is turned on the medicine portion 23 from the lower side of the umbrella portion 21. Thus, it can be easily replenished without being disturbed by the umbrella part 21.

  FIG. 5 shows still another form of use of the insect repellent. It becomes the structure which affixes a sheet piece to the circumference | surroundings of the fence 51 stretched around the vegetable garden 50 using the said adhesive layer. Therefore, it goes without saying that the sheet piece has a length that takes into account the length of the fence 51. Also in this case, the region 210 is horizontally bent to form the umbrella portion 21, and the region 230 is used to form the drug portion 23.

  As a result, pests such as licks that try to enter the vegetable garden where vegetables are cultivated can be eliminated or captured. In this case as well, at the corner portion of the fence, the continuity of the sheet pieces can be maintained by extending the bellows, so that it is possible to introduce a pest from the corner portion into the fence. In FIG. 5, the sheet piece is cut at the corner so that the umbrella part 21 and the medicine part 23 can be seen.

  As described above, since the insect repellent according to the present invention is assembled from one bellows sheet, the cost is very low. Also, the licks and ants that crawl up from under the fences of fruit trees and vegetable gardens can be completely removed or captured by the medicine of the medicine part 23, and the bellows sheet can absorb the growth of the tree, Even if the diameter of the tube increases, it can withstand long-term use.

  Since the present invention is inexpensive and can easily eliminate pests, it is considered that it can sufficiently withstand the use of not only commercial orchards but also those who grow vegetables in home gardens, and industrial utility value Is expected to be large.
