Description

Technical Field

[0001] The present invention omits the top surface part having the assembling function and visual shielding function of the conventional assembled cockroach trap and the side surface part forming the access opening, and relates to a plate-type cockroach catcher that uses a visibility-shielding covering member which does not cause visual hygienic discomfort during disposal on the bottom surface part having the catching function.

Background Art

[0002] As a proposal of a conventional plate-type cockroach catcher that omits the top surface part having an assembling function and a visual shielding function and the side surface part forming an access opening, and is formed only by a bottom surface part having a catching function, for example, a "Cockroach Catcher" (Patent Document 1) has been proposed, in which the peripheral edge of a single rectangular paperboard is folded inward in a tapered shape to form a tread, and an adhesive is further applied to the upper part of the paperboard.

[0003] However, the proposal of the aforementioned "Cockroach Catcher" (Patent Document 1) requires the peripheral edge of the paperboard to be folded into a tapered shape during use, and is not provided with a visibility shielding means that prevents visual hygienic discomfort at the time of disposal.

[0004] In addition, a "Cockroach Trap" (Patent Document 2) has been proposed, which comprises a dish-shaped container body made of a water-resistant thin material, which has a rising peripheral wall on the peripheral edge of the bottom plate part, and a downwardly sloping skirt part integrally formed continuously at the upper end of the peripheral wall, and an adhesive layer for catching applied and formed on the bottom plate part of the dish-shaped container body.

[0005] However, in the proposal of the aforementioned "Cockroach Trap" (Patent Document 2), since the adhesive layer is applied on the bottom plate part of the dish-shaped container body, complicated manufacturing equipment and manufacturing processes are required to apply the adhesive layer to the recess in the manufacturing process, which leads to an increase in manufacturing cost, and it is not provided with a visibility shielding means that prevents visual hygienic discomfort at the time of disposal.

[0006] Furthermore, a "cockroach trap for capture and survey" (Patent Document 3) has been proposed to simplify the counting survey after capture.

[0007] However, the proposed "cockroach trap for capture and investigation" (Patent Document 3) employs a method in which a housing-shaped trap body made of synthetic resin has multiple entrances on its peripheral wall, the bottom of the trap body is made of a transparent thin sheet of synthetic resin, and an attractive adhesive is applied to the central part of the transparent thin sheet. As a result, the structure of the cockroach trap body is made up of multiple parts, which leads to a rise in the unit price of the product, and also requires a complex and time-consuming assembly process when installing it.

[0008] In view of the above-mentioned problems, the applicant has conceived of a way to improve the probability of capturing cockroaches that enter the cockroach trap, while simultaneously simplifying the structure of the cockroach trap itself and reducing costs. As a result, the applicant has developed a plate-type cockroach trap that omits the top surface which has an assembly function and a visual blocking function, and the side surface which forms the entrance and exit, and uses a visual blocking covering member on the bottom surface which has a capture function, so as not to cause visual or hygienic discomfort when discarded. This has led to the proposal of the "plate-type cockroach trap" in the present invention. [Prior art documents] [Patent Documents]

[0020] The plate-type cockroach trap 10 of the present invention is characterized by its use of a visually obscuring covering member on the bottom surface, which has a trapping function, to prevent visual and hygienic discomfort when it is disposed of. This is a feature of the plate-type cockroach trap 10 of the present invention. Embodiments of the present invention will be described below with reference to the drawings.

[0021] Furthermore, the plate-type cockroach 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 exhibit the same effects. [Examples]

[0022] Figure 1 shows the plate-type cockroach trap of the present invention. fruit This is an explanatory diagram showing the application method. Figure 1(a) is an exploded perspective view of the plate-type cockroach trap 10 of the present invention. The plate-type cockroach trapping device 10 of the present invention is Used together with the visibility-blocking cover member 21 A rectangular or square plate-type cockroach trap consisting of a single plate with open top and side surfaces, comprising a trapping base plate 11, an adhesive sheet 17, and an attractant 20 And, It is composed.

[0023] The capture base plate 11 is press-molded from a thin material such as cardboard, foamed resin, resin film, pulp mold, or aluminum foil. The periphery of the capture base plate 11 has a tapered footboard edge portion 12 that has a predetermined height and width and slopes gently outward, and an inner lower wall surface 14 formed at the base of the footboard edge portion 12. Furthermore, on the inner periphery of the recess 13 surrounded by the footboard edge portion 12, a retaining projection 15 for housing and fixing the adhesive sheet 17 is provided, spaced from the bottom surface of the recess 13 by the thickness of the adhesive sheet 17. Dimensionally, it is formed in the shape of a rectangular or square sheet, approximately 110 mm in length, 80 mm in width, and approximately 0.1 to 0.2 mm in thickness.

[0024] The capture base plate 11 is made of a thin material such as cardboard, foamed resin, resin film, pulp mold, or aluminum foil, so that it can be easily disposed of with a single touch as "burnable waste" without causing any visual or hygienic discomfort.

[0025] The treadle edge portion 12 is formed on the periphery of the capture base plate 11 with a predetermined height, width, and inclination angle, and includes an inner lower wall surface 14 that is inevitably formed when the treadle edge portion 12 is formed. When the antennae of a fleeing cockroach G come into contact with the inner lower wall surface 14, it senses the presence of an obstacle, which slows down the cockroach G's escape speed and improves the probability of capture.

[0026] The inner lower wall surface 14 is a wall surface formed substantially perpendicular to the base of the treadle edge 12. When a cockroach escapes, it climbs the inner lower wall surface 14, causing the cockroach's weight to be on its hind legs and part of its body or legs to stick to the adhesive layer 19, thereby improving the chances of capture. Additionally, when the cockroach escapes, it recognizes the obstacle provided by the inner lower wall surface 14, slowing its escape speed and further improving the chances of capture.

[0027] The restraining projection 15 is provided on the inner peripheral edge of the recess 13 surrounded by the footboard edge 12 to store and fix the adhesive sheet 17, and is installed with a gap equal to the thickness of the adhesive sheet 17 from the bottom surface of the recess 13. By pushing the adhesive sheet 17 into the recess 13 from above, the adhesive sheet 17 can be set into the cockroach trap 10 with a single touch.

[0028] The adhesive sheet 17 consists of a sheet-shaped base placed on the capture base plate 11, an adhesive layer 19 applied to the surface of the base, and a release paper 18 covering the surface of the adhesive layer 19. Furthermore, by separating the manufacturing line for the adhesive sheet 17 from the manufacturing line for the capture base plate 11, it is possible to simultaneously simplify the manufacturing equipment and improve production efficiency.

[0029] The attractant 20 is manufactured in liquid, solid, granular, or gel form, for example, from food-derived components such as fish meal or sugars, and is either contained in the adhesive layer 19 or placed on top of the adhesive layer 19.

[0030] Visibility-blocking covering member 21 has a shape that covers at least the surface of the plate-type cockroach trap 10. It is formed as and made of an opaque material. It is for example, Tissue paper, kitchen paper, toilet paper, paper towels, etc. are commonly kept in households. Doka It consists of.

[0031] Figure 1(b) is a cross-sectional diagram illustrating the capture state of the plate-type cockroach trap 10 of the present invention. The cockroach (G) capture situation is described below. (1) A cockroach G attempting to enter the plate-type cockroach trap 10 from any direction will climb the footpeg edges 12 provided on each of the four sides of the plate-type cockroach trap 10. At this time, the cockroach G's antennae will be facing upwards, making it difficult for it to sense the presence of the adhesive layer 19, and thus the cockroach G will easily enter the plate-type cockroach trap 10. (2) When a cockroach G tries to get down from the edge of the stepping board 12, the cockroach G's weight rests on its front legs and sticks to the adhesive layer 19, which improves the chances of capture. (3) When a cockroach G senses the presence of the adhesive layer 19 with its antennae and legs, it flees outwards. Due to the behavioral habits of cockroaches G, it is not possible to turn back, but if it tries to make a U-turn, it will flee in a circular motion while running, and the probability of capture increases as part of the cockroach G or its legs stick to the adhesive layer 19. (4) When the cockroach G climbs up the tip of the edge of the stepping board 12 in the direction of escape, the cockroach G's weight is placed on its hind legs and part of its body or legs stick to the adhesive layer 19, which increases the probability of capture. Furthermore, if the cockroach's legs are wet with moisture or oil, the chances of capturing it decrease.

[0032] Figures 1(c), (d), and (e) are explanatory diagrams showing the disposal state of the plate-type cockroach trap 10 of the present invention. (1) A cockroach G is captured by the adhesive layer 19 of the plate-type cockroach trap 10. (2) The plate-type cockroach trap 10 and the entire captured cockroach G are covered with the visibility-blocking covering member 21. (3) Gently press your finger against the top of the visibility-blocking cover member 21 to ensure that the visibility-blocking cover member 21 and the adhesive layer 19 are in close contact and adhere to each other. (The visibility-blocking cover member 21 and the adhesive sheet 17 will be in close contact without shifting.) (4) The captured cockroach G, the adhesive sheet 17, and the capture base plate 11 can be covered with the visibility-blocking cover member 21, allowing for easy disposal with a single touch without causing any visual or hygienic discomfort.

[0033] A means of manufacturing the plate-type cockroach trap 10 composed of the above components is, for example, Since the capture base plate 11 is a rectangular or square thin plate, it can be manufactured inexpensively and in large quantities by passing a strip of material through a conveyor-type hot rolling mill, which simultaneously performs embossing and punching. The adhesive sheet 17 and the attractant 20 are manufactured by specialized chemical supply manufacturers, thereby reducing the unit cost of the products. Visibility-blocking covering member 21 is for example Tissue paper, kitchen paper, toilet paper, and paper towels are commonly kept in the home. For example, using malleable aluminum foil as a substitute. It is possible. Based on the above, a manufacturer selling the plate-type cockroach trap 10 of the present invention can develop the product with minimal capital investment by utilizing domestic and international suppliers in the initial stages of manufacturing, without requiring large-scale capital investment. [Examples]

[0034] Figure 2 is an explanatory diagram showing another embodiment of the plate-type cockroach trap of the present invention. Figure 2(a) is an exploded perspective view of the plate-type cockroach trap 10 of the present invention. The plate-type cockroach trapping device 10 of the present invention is Used together with the visibility-blocking cover member 21 A rectangular or square plate-type cockroach trap consisting of a single plate with open top and side surfaces, comprising a trapping base plate 11, an adhesive sheet 17, and an attractant 20 And, It is composed.

[0035] The capture base plate 11 is press-formed from a metal plate or synthetic resin material. The periphery of the capture base plate 11 has a tapered treadle edge portion 12 that is of a predetermined height and width and slopes gently outward, and an inner lower wall surface 14 formed at the base of the treadle edge portion 12. Furthermore, a retaining projection 15 for storing and fixing the adhesive sheet 17 is provided on the inner periphery of the recess 13 surrounded by the treadle edge portion 12, with a gap equal to the thickness of the adhesive sheet 17 from the bottom surface of the recess 13. A removal hole 16 for inserting a finger when attaching or detaching is provided on the bottom surface of the recess 13. Dimensionally, it is formed as a thin plate with a length of approximately 110 mm, a width of 80 mm, and a thickness of approximately 1 to 2 mm.

[0036] The capture base plate 11 is made of a metal plate (e.g., aluminum, stainless steel, plated iron plate) or a heat-resistant synthetic resin material (e.g., PP (polypropylene) or PS (polystyrene)), so that it can be reused multiple times by sterilizing it with boiling water.

[0037] The treadle edge portion 12 is formed on the periphery of the capture base plate 11 with a predetermined height, width, and inclination angle, and includes an inner lower wall surface 14 that is inevitably formed when the treadle edge portion 12 is formed. When the antennae of a fleeing cockroach G come into contact with the inner lower wall surface 14, it senses the presence of an obstacle, which slows down the cockroach G's escape speed and improves the probability of capture.

[0038] The inner lower wall surface 14 is a wall surface formed in a substantially vertical shape at the base of the treadle edge portion 12. When a cockroach escapes, it climbs the inner lower wall surface 14, and as a result, the weight of the cockroach G is placed on its hind legs, causing part of its body or legs to stick to the adhesive layer 19, thereby improving the probability of capture. Additionally, when the cockroach G escapes, it recognizes the obstacle provided by the inner lower wall surface 14, which slows down its escape speed and further improves the probability of capture.

[0039] The restraining projection 15 is provided on the inner peripheral edge of the recess 13 surrounded by the footboard edge 12 to store and fix the adhesive sheet 17. By installing it with a gap equal to the thickness of the adhesive sheet 17 from the bottom surface of the recess 13, the adhesive sheet 17 can be pushed in from above the recess 13, allowing the adhesive sheet 17 to be stably set on the cockroach trap 10 with a single touch.

[0040] The removal hole 16 is formed on the bottom surface of the recess 13 of the capture base plate 11, and is shaped so that a finger can be inserted from below when attaching or detaching the adhesive sheet 17.

[0041] The adhesive sheet 17 consists of a sheet-shaped backing placed on a base plate, an adhesive layer 19 applied to the surface of the backing, and a release paper 18 covering the surface of the adhesive layer 19. Furthermore, by separating the manufacturing line for the adhesive sheet 17 from the manufacturing line for the capture base plate 11, it is possible to simultaneously simplify the manufacturing equipment and improve production efficiency.

[0042] The attractant 20 is manufactured in liquid, solid, granular, or gel form, for example, from food-derived components such as fish meal or sugars, and is either contained in the adhesive layer 19 or placed on top of the adhesive layer 19.

[0043] Visibility-blocking covering member 21 has a shape that covers at least the surface of the plate-type cockroach trap 10. It is formed as and made of an opaque material. It is for example, Tissue paper, kitchen paper, toilet paper, paper towels, etc. are commonly kept in households. Doka It consists of.

At this time, the cockroach G's antennae will be facing upwards, making it difficult for it to sense the presence of the adhesive layer 19, and thus the cockroach G will easily enter the plate-type cockroach trap 10.

[0045] Figures 2(c), (d), and (e) are explanatory diagrams showing the disposal state of the plate-type cockroach trap 10 of the present invention. (1) A cockroach G is captured by the adhesive layer 19 of the plate-type cockroach trap 10. (2) The plate-type cockroach trap 10 and the entire captured cockroach G are covered with the visibility-blocking covering member 21. (3) Gently press your finger against the top of the visibility-blocking cover member 21 to ensure that the visibility-blocking cover member 21 and the adhesive layer 19 are in close contact and adhere to each other. (The visibility-blocking cover member 21 and the adhesive sheet 17 will be in close contact without shifting.)

(5) The captured cockroach G and adhesive sheet 17 can be covered with the visibility-blocking covering member 21, allowing for easy disposal with a single touch without causing any visual or hygienic discomfort.

[0046] The plate-type cockroach trap 10, as described above, can be molded as a metal plate or synthetic resin component, thereby enabling the provision of an economical, reusable plate-type cockroach trap 10. [Examples]

[0047] figure 3 This is an explanatory diagram showing another embodiment of the plate-type cockroach trap of the present invention. figure 3 (a) is an overall perspective view of the adhesive sheet 17. figure 3 (b) is an enlarged cross-sectional diagram of the adhesive sheet 17. figure 3 (c) is a cross-sectional diagram illustrating the usage condition. The plate-type cockroach trap 10 in the present invention employs a method in which the surface of the adhesive layer 19 is processed to have an uneven surface.

[0048] The adhesive sheet 17 consists of a rectangular or square base placed on the bottom surface of the plate-type cockroach trap 10, an adhesive layer 19 applied to the surface of the base, and a release paper 18 covering the surface of the adhesive layer 19. By embossing the surface of the adhesive layer 19 to create an uneven, linear, patterned, or wavy shape, the contact area between the cockroach G and the adhesive layer 19 is increased, thereby increasing the chances of capture. Dimensionally, it is formed to be slightly smaller to fit within the dimensions of the bottom surface of the capture base plate 11.

[0049] The plate-type cockroach trap 10, as described above, is made possible by applying an embossed surface E, such as a linear, patterned, or wave-shaped pattern, to the surface of the adhesive layer 19, thereby increasing the contact area between the cockroach G and the adhesive layer 19 and improving the probability of capture.

The figure is an overall perspective view showing the packaging of the plate-type cockroach trap 10. The plate-type cockroach trap 10 of the present invention is packaged and stored in sets of multiple plates in a storage case P made of synthetic resin. The plate-type cockroach trap 10 of the present invention, when packaged and stored, offers several advantages, including requiring minimal display space, having a low unit price, low distribution costs, minimal storage and placement space within the home, no assembly required, a shorter disposal period after capture, improved capture probability by placing multiple traps, and improved kitchen design. [Industrial applicability]

[0051] The plate-type cockroach trap of the present invention omits the top surface, which has an assembly function and a visual obstruction function, and the side surface, which forms an entrance, of conventional assembly-type cockroach traps, and instead has a bottom surface with a trapping function that provides a visual obstruction function for cockroach carcasses when disposed of. Visibility-blocking covering memberBecause it can be easily disposed of with a single touch without causing any visual or hygienic discomfort, we believe that the "plate-type cockroach trap" of the present invention has extremely great industrial potential.
