Description

Technical Field

[0001] The present invention relates to a fly trap that can pull out the outermost circumference of the adhesive roll paper when a large number of flies are captured on the adhesive roll paper, temporarily peel it off from the cutting position by the perforation, and cut it off.

Background Art

[0002] Conventionally, commercially available household fly traps include ribbon type, solid attractant type, sheet type, roll paper type, electric shock type, etc.

[0003] As a proposal for the above-mentioned ribbon type fly trap, for example, a "fly trap" (Patent Document 1) that is set indoors, is easy to actively capture, is gentle on the human body and the environment, and is safe has been proposed.

[0004] However, since the proposal of such a "fly trap" (Patent Document 1) is a proposal for a ribbon type fly trap aimed at capturing flies generated particularly indoors, the dead bodies of the captured flies are adhered to the surface of the ribbon. Since it is captured in a state where it is suspended in a bare state, it comes into contact with the skin and clothes of people doing housework, causing discomfort.

[0005] In addition, as a proposal for a solid attractant type fly trap, for example, an "attraction trap" (Patent Document 2) that has excellent attraction performance and can capture flies well has been proposed.

[0006] However, the proposed "attractant trap" (Patent Document 2) is an attractant trap that stores a solid attractant inside a container and has a capture opening on the surface of the container for attracting and capturing flies. The capture opening is provided along the circumferential surface of the side wall of the container so as to face the solid attractant. This trap employs a method of trapping flying flies with a cylindrical gel-like solid attractant. However, if left for a long time, the solid attractant dries out and the capture efficiency decreases. Also, because the capture opening is located at the bottom, flies that enter through the capture opening reach the surface of the solid attractant, ingest the insecticidal component within the solid attractant, and die upon contact with the insecticidal component, causing their carcasses to fall around the solid attractant. This capture method requires a considerable time response in terms of the time required for capture and is not a time-efficient capture method.

[0007] Furthermore, as a proposal for a sheet-type fruit fly trap, for example, a "flying insect trap" (Patent Document 3) has been proposed that, when using a highly moist insecticide-holding material, exhibits a high attraction effect and capture efficiency for flying insects, especially fruit flies, over a long period of time, and is also simple in structure and easy to use.

[0008] However, the proposed "flying insect trap" (Patent Document 3) is a flying insect trap in which a liquid chemical composition is held in a moist state on a nonwoven fabric carrier, and a liquid chemical holder is housed in a tray, and a lid with an opening is fitted onto the hollow top surface of the tray. The proposed chemical composition contains an insecticidal component, an attractant component, and a moisturizing component, and the nonwoven fabric carrier has a bulk density of 0.02 to 0.1 and a side end thickness of 5 to 30 mm. As a result, the time required for fruit flies to enter through the opening in the base and be captured by the liquid chemical holder impregnated with the attractant and insecticidal components requires a considerable time response, making it not a time-efficient trapping method, and the trapping status cannot be judged at a glance.

[0009] Furthermore, as a proposal for a roll-paper type fruit fly trap, for example, "Cartridge for pest trapping device, pest trapping device, and pest trapping method" (Patent Document 4) has been proposed, which can provide a pest trapping technology that can more accurately count the number of captured pests.

[0010] However, the proposed "cartridge for insect trapping device, insect trapping device, and insect trapping method" (Patent Document 4) is a trap comprising an adhesive roll paper for trapping insects in a roll shape, a paper feed roller that rotatably supports the adhesive roll paper, a winding roller that winds up the adhesive roll paper, a transparent cover sheet that is attached to the adhesive surface of the adhesive roll paper wound up on the winding roller, and a cover sheet roller that rotatably supports the cover sheet in a roll shape. As such, the support roller section is configured to separate the surface of the adhesive roll paper used into the adhesive roll paper and the cover sheet, requiring a large installation space on a narrow kitchen table, and the system employs an electric motor to wind up the sheet portion to which the captured fruit flies have been stuck, thus limiting the installation location depending on the location of the power outlet and the length of the power cable.

[0011] Furthermore, as a proposed electric fly trap, for example, a "day and night flying insect electric killer" (Patent Document 5) has been proposed, which blows an airflow containing an attractant onto the electric grid of an electric insect killer, causing flying insects to mistake it for a place with food and then be killed by electric shock.

[0012] However, the proposed "day and night flying insect pest electric insect killer" (Patent Document 5) had limitations: drain flies and other insects tended to have a low attraction effect to the attractant light, and the installation location of the insect killer was limited by the location of the power outlet and the length of the power cable.

[0013] The applicant, in consideration of the above-mentioned problems, conceived the idea of ​​a small fly trap that would have the following features: small installation space, no visual or hygienic sense of uncleanliness, no contact with the skin or clothing of people doing housework, easy replacement of adhesive roll paper, simple structure making maintenance easy, high capture efficiency, low unit cost, small size and light weight, no restrictions on installation location, and long-lasting capture effect. Based on this concept, the applicant developed a small fly trap that has the above features and, when a large number of small flies are captured on the adhesive roll paper, allows the outermost layer of the adhesive roll paper to be pulled out and gradually peeled off at the perforated cut line, leading to the proposal of the "small fly trap" in the present invention.

(Example 1) [Figure 2]This is an explanatory diagram showing another embodiment of the fruit fly trap of the present invention. (Example 2) [Figure 3] This is an explanatory diagram showing another embodiment of the fruit fly trap of the present invention. (Example 3) [Figure 4] This is an explanatory diagram showing another embodiment of the fruit fly trap of the present invention. (Example 4) [Modes for carrying out the invention]

[0026] The most distinctive feature of the fruit fly trap 10 in the present invention is that when a large number of fruit flies C are captured on the adhesive roll paper 19, the outermost portion of the adhesive roll paper 19 can be pulled out and gradually peeled off and cut along the perforations 20. Embodiments of the present invention will be described below with reference to the drawings.

[0027] Furthermore, the fruit fly trap 10 of the present invention is not limited to the embodiments described below, and can be modified as appropriate within the scope of the technical concept of the present invention, that is, within the range of shapes and dimensions that can achieve the same effect. Furthermore, the fruit fly trap 10 of the present invention is described as targeting four types of fruit flies C: Drosophila melanogaster, Phorid flies, Drain flies, and Fungus gnats. [Examples]

[0028] Figure 1 is an explanatory diagram showing an embodiment of the fruit fly trap of the present invention. Figure 1(a) is an exploded perspective view of the fruit fly trap 10. Figure 1(b) is an overall perspective view of the fruit fly trap 10. Figure 1(c) is a cross-sectional diagram illustrating the usage of the fruit fly trap 10. The fruit fly trap 10 of the present invention consists of a reel stand 11, an adhesive roll paper 19, and an attractant sheet 21.

[0029] The winding shaft stand 11 consists of a top cap 12, a winding shaft sleeve 13, a winding shaft base 14, and a base cap 18. It is made of molded plastic or polypropylene, and is preferably blue or yellow, which are preferred by fruit flies C.

[0030] The top cap 12 is formed by screwing it onto the upper end of the winding shaft sleeve 13, with a shape that covers the adhesive roll paper 19 from above. It is shaped like a mushroom cap, and by being attached so as to overhang the adhesive roll paper 19, the area around the adhesive roll paper 19 is opened 360 degrees in all directions, and the shape is designed so that it does not come into contact with the skin or clothing of a person doing housework. Furthermore, because the top cap 12 is shaped like an umbrella that covers the adhesive roll paper 19 from above, it can eliminate the visual sense of unsanitary conditions and discomfort for women who are uncomfortable directly seeing the carcasses of captured fruit flies C.

[0031] The winding shaft sleeve 13 has a sleeve-like shape that is inserted into the cylindrical hollow core of the adhesive roll paper 19, with its upper end screwed onto the top cap 12 and its lower end screwed onto the winding shaft stand 11. Furthermore, because the adhesive roll paper 19 is designed to rotate easily during use, approximately one full turn of the outermost circumference of the adhesive roll paper 19 from which the fruit fly C has been captured can be peeled off and cut away. Furthermore, the screw-in sections at the upper and lower ends are designed with reverse threads to facilitate installation and removal.

[0032] The winding shaft base 14 is shaped to stably support the winding shaft sleeve 13, and the attractant sheet 21 is housed in a hollow storage section 15 formed by screwing a base cap 18 onto the lower part. Multiple vents 16 are provided on the upper surface of the flange section 17 to allow the odor components 24 of the attractant emitted from the attractant sheet 21 to pass through. In terms of shape, it is formed to resemble a vertical lamp stand and can be functionally placed on a narrow kitchen sink without interfering with washing dishes.

[0033] The adhesive roll paper 19 is formed by having a release surface on the back and an adhesive layer applied to the surface of a roll of cardboard, which is wound onto a cylindrical hollow core of a predetermined width and has perforations 20 that allow it to be cut to a predetermined length. When many fruit flies C are captured on the adhesive roll paper 19, the outermost circumference of the adhesive roll paper 19 can be pulled out from the perforations 20 and partially peeled off and cut away. Furthermore, the capture efficiency can be improved by impregnating the cylindrical hollow core with an attractant odor component 24, similar to scented toilet paper.

[0034] The attractant sheet 21 is formed by applying an attractant 23 that attracts fruit flies C to the surface of a cardboard base 22 that is shaped to be housed inside the winding shaft base 14, and covering the surface of the attractant 23 with release paper 25. In terms of shape, it is formed into a round or rectangular shape and is packaged individually or in packs of multiple sheets for spare replacement. Furthermore, the attractant 23 can also be solidified, gelled, or powdered and incorporated not only inside the winding shaft base 14 but also inside the top cap 12 or the winding shaft sleeve 13.

[0035] The fly trap 10, constructed as described above, aims to provide a fly trap 10 that has the following features: it requires little installation space, does not give a visual or hygienic impression of being unclean, does not come into contact with the skin or clothing of people doing housework, the adhesive roll paper 19 is easy to replace, the simple structure makes maintenance easy, it has high trapping efficiency, the unit price is low, it is small and lightweight, it can be installed anywhere, and it has a long trapping effect. [Examples]

[0036] Figure 2 is an explanatory diagram showing another embodiment of the fruit fly trap of the present invention. Figure 2(a) is an overall perspective view of a single attractant sheet 21. Figure 2(b) is an overall perspective view of the multiple units of the attractant sheet 21. The fruit fly trap 10 of the present invention employs a method in which the odor component 24 of the attractant sheet 21 contains odor components preferred by each type of fruit fly C.

[0037] The attractant sheet 21 is shaped to fit within the hollow storage section 15 of the winding shaft base 14, and is formed as a sheet by applying the attractant 23 to the upper surface of the backing paper 22 and covering the upper surface with release paper 25. It can be formed as a single sheet or by stacking multiple sheets.

[0038] The fruit fly trap 10 of the present invention is described as targeting four types of fruit flies C: Drosophila melanogaster, Phorid flies, Drain flies, and Fungus gnats C. (1) Drosophila They have red eyes and a yellow body, and they appear in kitchen sink strainers and trash cans containing food waste. The main components of the attractant sheet 21 are derived from ingredients such as ripe or rotten fruits, alcohols like sake and wine, and seasonings like mirin and vinegar. (2) Phorid flies They have a generally brownish body, but their rear end is dark, and they are found in kitchen sink strainers and trash cans containing food waste. The main components of the attractant sheet 21 are formulated from the odor components of decaying plants and food waste (especially meat and vegetables). (3) Drain flies They have large wings and are commonly called "toilet flies," as they breed in damp places such as toilets, bathrooms, and kitchen drains. The main components of the attractant sheet 21 are formulated using components derived from toilet and sewage odors. (4) Fungus gnats They have a slender body shape with long wings and long legs, and they can be found on hot days with temperatures around 30°C, in places with high humidity of around 70%, and in stagnant water in vases. The main components of the attractant sheet 21 are formulated using components derived from mushrooms that grow in the soil and from the ornamental plants themselves.

[0039] The fly trap 10, as described above, aims to provide a fly trap that can improve trapping efficiency by narrowing down the types of fly C present, by providing an attractant sheet 21 that is applied to the upper surface of the cardboard base 22 with a mixture (mixable) of odor components preferred by each type of fly C as described above. [Examples]

[0040] Figure 3 is an explanatory diagram showing another embodiment of the fly trap of the present invention. The fruit fly trap 10 of the present invention employs a method of providing a wall-mounting mounting means 26 or a stationary mounting means 27 on the bottom surface of the base cap 18 of the winding shaft base 14.

[0041] Figure 3(a) is an exploded perspective view of the fruit fly trap 10. Figure 3(b) is an explanatory diagram showing the fruit fly trap 10 in use, placed on the top surface of a kitchen sink. Figure 3(c) is an explanatory diagram showing the usage configuration when the kitchen is placed on the wall. Figure 3(d) is an explanatory diagram showing the usage configuration when placed on the kitchen ceiling.

[0042] The wall-mounting mounting means 26 or the stationary mounting means 27 can be efficiently placed on the top surface of the kitchen sink, the wall, the ceiling, etc., where fruit flies C fly, for example, by attaching a magnetic sheet, double-sided tape, suction cup, clip, etc. to the bottom surface of the base cap 18. Additionally, a hook is provided at the top of the canopy cap 12, allowing it to be suspended by a string or other means.

[0043] The fruit fly trap 10, as described above, is designed to be compact so as not to interfere with washing dishes even in a small kitchen space. Furthermore, the top cap 12 prevents contact with the adhesive roll paper 19. By placing it near the corner of the kitchen sink, which is the source of putrid odors, the aim is to provide a fruit fly trap 10 that can achieve unprecedented trapping efficiency. [Examples]

[0044] Figure 4 is an explanatory diagram showing another embodiment of the fruit fly trap of the present invention. Figure 4(a) is an exploded perspective view of the fruit fly trap 10. Figure 4(b) is an overall perspective view of the fruit fly trap 10. Figure 4(b) is a cross-sectional diagram of the fruit fly trap 10. The fruit fly trap 10 of the present invention employs a method that incorporates an AC power or DC power type phototactic illumination device 28 within the winding shaft stand 11.

[0045] The phototactic lighting device 28 consists of an induced light 29 (UV light / near-ultraviolet LED lamp, fluorescent lamp, incandescent bulb), a control board 30, an AC power cord 31 or a DC power supply 32 (battery), and an ON / OFF switch 33, and is installed inside the winding shaft stand 11. Although the diagram shows the unit housed within the winding shaft base 14, it is also possible to house it within the zenith portion of the canopy cap 12.

[0046] The fruit fly trap 10 of the present invention utilizes the fact that most fruit flies C are organisms that exhibit "positive phototaxis," meaning they are attracted to light, and are particularly strongly attracted to ultraviolet light. It is constructed using an attractant light 29 (UV light / near-ultraviolet LED lamp, fluorescent lamp, incandescent bulb) to attract these flies. The structure attracts fruit flies C with an attractant light 29 emitting wavelengths around 365 nm, which are said to be preferred by fruit flies C, and a sheet-like attractant 23, and then captures them with adhesive roll paper 19. Furthermore, since fruit fly C has a color recognition function that particularly recognizes blue and yellow, it is also possible to use fluorescent or incandescent light bulbs that are colored blue or yellow. One of the advantages of this pest control method is that it does not use chemicals such as poison bait, and employs a physical extermination method that does not involve any mechanical elements, making it safe to use in homes with children or pets. However, the Attractant Light 29 only attracts flying adult insects; the most effective method of eradication is to identify the source of the infestation and clean and remove it. Furthermore, to reduce the occurrence of fruit flies (C), combining measures such as pouring boiling water down drains and disposing of food waste frequently will yield a higher extermination effect. Furthermore, the attractant light 29 attracts insects with specific ultraviolet (UV) wavelengths that they prefer and captures them with adhesive roll paper 19. This is effective and does not require any chemicals. In addition, darkening the entire room or placing the fruit fly trap 10 near the source of the infestation (garbage, drains, houseplants) will result in even greater extermination effectiveness. On the other hand, while it is effective against blowflies and fruit flies, it may not be as effective against drain flies, so it is important to avoid competition with other lights.

[0047] The fruit fly trap 10, as described above, aims to provide a fruit fly trap that can improve capture efficiency to an unprecedented degree by luring fruit flies C with a visual attraction element provided by an attractant light 29 and an olfactory attraction element provided by an attractant 23, and then capturing the fruit flies C with a physical element provided by an adhesive roll paper 19. [Industrial applicability]

[0048] The fruit fly trap of the present invention is a unique fruit fly trap that possesses many features, including requiring minimal installation space, not appearing unsanitary or unhygienic, not coming into contact with the skin or clothing of people doing housework, easy replacement of adhesive roll paper, simple structure making maintenance easy, high capture efficiency, low unit cost, small size and light weight, can be installed anywhere, and has a long-lasting capture effect. Therefore, we believe that the "fruit fly trap" of the present invention has extremely great industrial applicability. [Explanation of Symbols]
