Description

  The present invention relates to an animal repellent that repels birds and beasts such as starlings with sulfur sublimation gas.

  Conventionally, what was disclosed by patent document 1 as this kind of animal repellent is known. This animal repellent device is composed of a repellent container containing sulfur, which is a repellent, and a heater for heating the repellent container. When repelling birds and beasts, place animal repellents at places where birds and beasts appear and liquefy sulfur with the heat of the heater. Thereby, since sulfur evaporates at the place where birds and beasts appear, gas is generated, so that birds and animals do not approach the place where they appear due to sulfur gas odor.

No. 6-16528

  As described above, the conventional animal repellent has a step of heating and liquefying sulfur in order to increase the amount and concentration of sulfur gas. However, although the amount and concentration of sulfur gas increase, at the same time, the temperature of the gas also increases, making it flammable and dangerous. In addition, because the place where animal repellents are installed (animal habitat) is outdoors, even if a large amount of gas is temporarily released in large quantities, the gas may remain in the habitat due to the influence of wind or the like. Therefore, the conventional animal repellent device could not continuously repel animals.

  An object of the present invention is to provide an animal repellent device capable of releasing a high concentration of sulfur sublimation gas without heating sulfur and realizing a continuous animal repelling action in view of the above-mentioned conventional problems. There is.

  In order to solve the above-mentioned problems, the animal repellent according to the invention of claim 1 is a repellent made of sulfur or a sulfur mixture and generating a sulfur sublimation gas, containing the repellent and at least a sulfur sublimation gas at the bottom. The bottomed cylindrical repellent accommodating part having a gas passage hole through which gas can pass and the sulfur sublimation gas that has passed through the gas passage hole are stored, and the sulfur sublimation gas passes at least above the center in the vertical direction of the side part. It has a structure including a bottomed cylindrical gas storage section having possible gas outflow holes.

  According to the first aspect of the invention, the repellent contained in the repellent storage part sublimes to generate sulfur sublimation gas. Here, when comparing the molecular weight of sulfur sublimation gas with the average molecular weight of air, sulfur sublimation gas is higher and sulfur sublimation gas is heavier than air. Therefore, the sulfur sublimation gas flows downward of the repellent storage part, and further flows into the gas storage part through the gas passage hole provided at the bottom of the repellent storage part. The sulfur sublimation gas that has flowed into the gas storage section stays on the bottom side of the gas storage section, and the gas concentration increases as the amount of sulfur sublimation gas inflow increases, while the storage height of the sulfur sublimation gas gradually increases. When the sulfur sublimation gas storage height reaches the height of the gas outflow hole, or when the animal repellent device is tilted by the wind and the animal repellent device is tilted and the height of the gas outflow hole is lowered. A high-concentration sulfur sublimation gas flows out from the outflow hole. Thereby, the smell of sulfur sublimation gas spreads around the animal repellent device, and birds and beasts do not come near.

  According to a second aspect of the present invention, in the animal repellent of the first aspect, the repellent containing part is disposed inside the upper part of the gas storage part, the top opening of the repellent containing part is closed, and at least the gas outflow hole is provided. It has a cover part which covers the site | part located from the outer side at intervals.

  According to the second aspect of the present invention, the cover body has a lid function of the repellent container, and prevents rainwater from entering the repellent container. Moreover, since rainwater does not enter the gas storage part through the gas outflow hole, rainwater does not collect in the gas storage part, and thereby the gas storage volume of the gas storage part does not become small.

  According to a third aspect of the present invention, in the animal repellent according to the second aspect, the cover portion is detachably provided in at least one of the repellent storage portion or the gas storage portion.

  According to the invention of claim 3, when the repellent is accommodated in the repellent accommodating part, the cover part is removed, the repellent is further introduced from the upper part of the repellent accommodating part, and the cover part is accommodated as the original repellent. What is necessary is just to attach to a part. In addition, the repellent can be easily replaced by opening and closing the cover.

  The invention according to claim 4 is the animal repellent device according to claim 1 to claim 3, wherein the cover portion has a string for hanging. Therefore, it is only necessary to tie this string to a roadside tree or the like. Can be installed.

  According to the present invention, the sulfur sublimation gas sublimated from the repellent is stored at a high concentration, and since this high concentration sulfur sublimation gas flows out to the surroundings, birds and beasts can be reliably avoided. Further, since the repellent naturally sublimes and sulfur sublimation gas is generated, it is possible to continuously repel birds and beasts.

  1 to 4 show an animal repellent device according to a first embodiment of the present invention. The animal repellent device 10 according to the present embodiment stores a repellent 11 that generates a gas odor that birds and beasts repel, a repellent container 12 that contains the repellent 11, and a sulfur sublimation gas sublimated from the repellent 11. A gas storage cylinder 13 and a cover body 14 for preventing rainwater from entering the repellent container 12 and the gas storage cylinder 13 are provided.

  The repellent 11 is made of solid sulfur or a sulfur mixture. Any substance that generates sulfur sublimation gas by natural sublimation may be used.

  The repellent-containing basket 12 is made of a synthetic resin, and is formed in a bottomed cylindrical shape having an open top surface, as shown in FIG. 2, and contains the repellent 11 inside. Moreover, the side plate of the repellent container 12 spreads outward as it goes upward from the bottom plate, so that repellent charging work to the repellent container 12 and repellent removal work from the repellent container 12 can be easily performed. It has become. Further, a plurality of gas passage holes 12 a are formed in the side plate and the bottom plate of the repellent-containing cage 12. The diameter of each gas passage hole 12a is designed to a size that does not allow the repellent 11 to pass, and the number of each gas passage hole 12a is large so that sulfur sublimation gas does not stay in the repellent-containing basket 12. It has become a piece. At the upper end of the repellent-containing basket 12, an annular flange portion 12b bent outward is provided. The lower surface of the flange portion 12 b is engaged with the upper end of the gas storage cylinder 13, while the upper surface of the flange portion 12 b is formed so as to contact the inner surface of the cover body 14. As a result, the flange portion 12 b serves as a connecting portion of the repellent container 12, the gas storage cylinder 13, and the cover body 14.

  The gas storage cylinder 13 is made of synthetic resin, and as shown in FIGS. 2 and 3, it is formed in a bottomed cylindrical shape having an upper surface opened with synthetic resin, and a sulfur sublimation gas storage space is formed inside thereof. Yes. The diameter of the gas storage cylinder 13 is formed larger than the diameter of the upper end diameter of the repellent storage basket 12, and the repellent storage basket 12 is disposed inside the upper part of the gas storage cylinder 13. Moreover, the repellent container 12 and the gas storage cylinder 13 are integrally coupled by bonding the upper end of the gas storage cylinder 13 and the flange portion 12b with an adhesive 15a or by thermal bonding. The height dimension of the gas storage cylinder 13 is formed larger than the diameter dimension, and the storage space for the sulfur sublimation gas extends in the height direction. In addition, a large number of gas outflow holes 13a are formed in the side plate of the gas storage cylinder 13 from approximately the center in the vertical direction to the upper part, and the sulfur sublimation gas that has flowed into the gas storage cylinder 13 flows into the space from the center in the vertical direction to the lower part. It comes to store.

  As shown in FIGS. 2 and 3, the cover body 14 is formed of a synthetic resin in an inverted cup shape. The upper surface of the cover body 14 covers the upper surface opening of the repellent container 12. The side plate of the cover body 14 has a diameter that is increased outward in the downward direction, and covers a portion of the gas storage cylinder 13 that faces the gas outflow hole 13a with an interval from the outside. As a result, the cover body 14 covers the repellent container 12 and the gas outflow holes 13 a of the gas storage cylinder 13 so that rainwater does not enter the repellent container 12 and the gas storage cylinder 13. In addition, the lower end of the resin string 16 is fixed to the center of the upper plate of the cover body 14 by an adhesive 15b, and the upper end of the string 16 is suspended from the place where the birds and beasts appear and disappear.

  The cover body 14 configured in this manner is detachably attached to the repellent container 12 and the gas storage cylinder 13 with screws 17. That is, a plurality of screw holes 12c, 13b, 14a facing each other are provided in the upper part of the repellent container 12, the gas storage cylinder 13, and the cover body 14, and screws 17 are screwed into the screw holes 12c, 13b, 14a. Yes.

  When avoiding the starling of the roadside tree 18 using the animal repellent device 10 according to the present embodiment, it is performed as follows.

  First, as shown in FIG. 3, the screws 17 are extracted from the screw holes 12 c, 13 b, and 14 a, and the cover body 14 is removed from the repellent container 12 and the gas storage cylinder 13. Thereby, the upper surface of the repellent container 12 is opened. Subsequently, the repellent 11 is put into the repellent-containing cage 12 from the upper surface opening. Thereafter, the cover body 14 is assembled again to the repellent container 12 and the gas storage cylinder 13 so that the upper surface opening of the repellent container 12 is covered, and the cover body 14 is attached to the repellent container 12 and the gas reservoir with each screw 17. It is attached to the cylinder 13.

  When the animal repellent device 10 is prepared in this manner, as shown in FIG. 4, the animal repellent device 10 is attached to the roadside tree 18 where the starlings stay. The attachment position of the animal repellent device 10 should be set at the upper part of the street tree 18 so that the sulfur sublimation gas is distributed throughout the street tree 18. The number of animal repellent devices 10 to be attached may be determined in accordance with the size of the roadside tree 18 and the like.

As described above, in the animal repellent device 10 attached to the roadside tree 18, the repellent 11 accommodated in the repellent-containing basket 12 naturally sublimes and flows into the repellent-containing basket 12 as sulfur sublimation gas. . Here, comparing the average molecular weight of air with the molecular weight of sulfur,
Average molecular weight of air; 28.966 g / mol
Molecular weight of sulfur; 32.066 g / mol
Since the sulfur sublimation gas is heavier than air, the sulfur sublimation gas in the repellent-containing cage 12 descends and flows into the gas storage cylinder 13 through the gas passage hole 12. The sulfur sublimation gas in the gas storage cylinder 13 flows toward the bottom of the gas storage cylinder 13, and the sulfur sublimation gas stays at the bottom of the gas storage cylinder 13. Thereby, the sulfur sublimation gas gradually increases in concentration at the bottom of the gas storage cylinder 13. Then, when the flow of the sulfur sublimation gas into the gas storage cylinder 13 continues, and when the range of the high concentration sulfur sublimation gas gradually increases and reaches the installation location of the gas outflow hole 13a, the high concentration Sulfur sublimation gas flows out from the gas outflow hole 13a.

  According to the animal repellent device 10 according to the present embodiment, as described above, a high concentration of sulfur sublimation gas is released to the street tree 18 where starlings gather, and the street tree 18 is covered with the sulfur sublimation gas. Starlings who dislike smell do not come to the roadside tree 18. Further, since the sulfur sublimation gas having a high concentration can be released without heating the repellent 11, it is safe and the repellent effect can be continuously executed.

  Further, when the wind flows through the roadside tree 18 and the animal repellent device 10 shakes, the gas storage cylinder 13 is tilted and the height of the gas outflow hole 13a is lowered, so that a large amount of sulfur sublimation gas in the gas storage unit 13 is present. To the outside. Thereby, since the sulfur sublimation gas concentration around the roadside tree 18 becomes very high, the repellent effect of starlings is further improved.

  Furthermore, since the cover body 14 covers the gas outflow hole 13a so that rainwater does not enter the gas storage cylinder 13, the rainwater does not collect in the gas storage section 13, and thus the gas storage volume of the gas storage section 13 is prevented. Does not become smaller.

  The cover body 14 covers the top opening of the repellent container 12 and prevents rainwater from entering the repellent container 12, but the cover body 14, the string 16, and the adhesive 15 b have poor water tightness. When there is a rainwater, it may be assumed that rainwater enters the repellent container 12. In such a case, rainwater comes into contact with the sulfur component of the repellent 11 and becomes unsuitable acidic water for the roadside tree 18, but this acidic water is stored in the gas storage unit 13 through the gas passage hole 12 a, No dripping on the roadside tree 18.

  Furthermore, since the cover body 14 is detachable from the repellent container 12 and the gas storage cylinder 13 by attaching and detaching the screws 17, the repellent 11 can be easily replaced.

  FIG. 5 shows an animal repellent device according to the second embodiment of the present invention. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The animal repellent device 10 according to the second embodiment is an improved attachment / detachment structure between the gas storage cylinder 13 and the cover body 14. That is, instead of the screw 17 and the screw holes 12c, 13b, and 14a described in the first embodiment, a male screw 13c is provided on the upper outer surface of the gas storage cylinder 13, and the upper inner surface of the cover body 14 corresponds to the male screw 13c. An internal thread 14b is provided.

  According to the present embodiment, since the cover body 14 and the gas storage cylinder 13 are detachable by the screwing operation and screwing operation of the male screw 13c and the female screw 14b, the screw parts are not attached as in the first embodiment. It becomes unnecessary, and assembly failure due to loss of the screw 17 does not occur. In addition, the repellent container 12 and the gas storage cylinder 13 are bonded together by heat bonding.

  In each of the above embodiments, a starling has been described as an example. However, the animal repellent device 10 according to each embodiment can be applied to all birds such as crows, and monkeys, antelopes, bears, etc., animals generally dislike sulfur smell, Any animal can be applied.
