Description

Technical Field

[0001] This utility model relates to a replaceable insert for an insect trap and an insect trap including such a replaceable insert. Background Technology

[0002] For some time, various devices have been used to capture arthropods, particularly insects. These devices typically include attraction mechanisms to lure insects to the trap. Attraction mechanisms may include, for example, food, light, heat, pheromones, or other odorous materials attractive to the respective insects. Some of these devices include means to prevent insects from leaving the device, such as a surface covered with an adhesive that allows the insects to adhere to it.

[0003] Insect trapping devices that combine adhesives used to trap insects with light are known. UV light, visible light, or combinations thereof can be used.

[0004] US2020 / 0113165A1 (P&G) discloses an insect light trap having a frame and a membrane having an adhesive surface. The frame may have a hinged cover that prevents the user from seeing dead insects during disposal.

[0005] WO2016 / 207430 (Zobele) discloses an insect light trap in which the refill portion includes a transparent or translucent frame or grid for bonding a sheet. A consumer can grasp the refill portion through the frame or grid without touching the bonding sheet, but the emitted light can still pass through the frame or grid.

[0006] JP2010-136630 (Sankyo Shodoku) discloses an insect light trap with a flat rectangular insert that can be folded to enclose dead insects inside for disposal.

[0007] JP2023-60723 (Shimada Corporation) discloses an insect light trap with a paper-based adhesive substrate folded into a pocket shape. If insects fall off the adhesive, they remain inside the pocket. The substrate is attached to a simple housing via spring clips, pins passing through holes in the substrate, etc. One problem with this design is that when mounted on the housing, insects cannot access it and / or the light source does not illuminate most of the substrate.

[0008] JP2003-92964 (Panasonic Electric Works) discloses an insect trap with an adhesive sheet that is bent or folded by a frame into the shape of a horizontally extending groove located below a light strip. The groove retains insects that may fall off the adhesive due to wind or gravity. The sheet may have slits or creases to facilitate folding after use to trap the insects inside.

[0009] WO2022047088A1 (P&G) discloses an arthropod trapping device comprising a base, a light-shielding element, and an insert. The light-shielding element may protrude on its outer surface and be recessed on its light-facing surface. The insert may include at least partially reflective, concave, light-facing surface on which an adhesive is disposed. The insert may be planar but flexible, allowing a user to flex, bend, or deflect the insert when it is inserted into the light-shielding element.

[0010] We need equipment that is easier to manufacture, easier to handle, and more sustainable. Utility Model Content

[0011] According to a first aspect of the present invention, an insect trap is provided. The insect trap includes a replaceable insert. The replaceable insert includes a body having a front surface and a rear surface, wherein the rear surface includes a coating comprising an adhesive for trapping insects. The body includes at least one fold line configured to fold the body along the fold line such that at least a portion of the rear surface can be folded over another portion of the rear surface. The body of the replaceable insert also includes multiple fold lines such that, when the replaceable insert is installed in the insect trap, the body is folded along the multiple fold lines into a curved shape (preferably a concave curved shape) of the rear surface.

[0012] According to a second aspect of the present invention, a replaceable insert as described above is provided.

[0013] Preferably, the replaceable insert is a sheet.

[0014] The replaceable insert according to this invention allows for easy handling and disposal after use. During use, insects are captured by being adhered to the rear surface via an adhesive. Before disposal, the replaceable insert can be folded along at least one fold line, such that one portion of the rear surface and the other portion are glued together by the adhesive, and the captured insect is enclosed between the two portions of the rear surface. Therefore, the captured insect is not exposed to the consumer, as is the case with the coating of the rear surface that has been folded together. The folded replaceable insert can then be conveniently discarded.

[0015] In one embodiment, at least one fold line includes a crease, notch, or perforation to facilitate folding of the replaceable insert. Preferably, the at least one fold line includes a crease. Preferably, each of the plurality of fold lines includes a crease.

[0016] In one embodiment, at least one fold line divides the rear surface into two identical / equal portions. In such an embodiment, the adhesive-coated rear surface is completely folded up, the folded replaceable insert has a minimal size, and neither the adhesive-coated rear surface portion nor any captured insects are displayed to the consumer.

[0017] In another preferred embodiment, the rear surface includes at least one adhesive-free area. The at least one adhesive-free area can be any part of the rear surface: at the top, bottom, middle, side, or center. This area can be created, for example, by folding a portion of the rear surface before applying adhesive, applying adhesive to the rear surface, and unfolding the folded portion of the rear surface. In the latter embodiment, there will be no adhesive on this portion of the rear surface that has been folded before applying adhesive. The adhesive-free area can also be created by simply not applying adhesive to it, i.e., leaving the adhesive-free portion untouched. In the adhesive-free area, the consumer can access the rear surface without adhering to it. For example, the consumer can grasp the replaceable insert with their thumb placed on the (adhesive-free) front surface and another finger placed on the adhesive-free portion of the rear surface. This is advantageous when the consumer needs to replace the replaceable insert. Preferably, at least one adhesive-free area is located at the top of the rear surface, i.e., on the pull tab.

[0018] In yet another preferred embodiment, the body of the replaceable insert is made of paper and / or cardboard, resulting in a sustainable product. Preferably, the replaceable insert is made of paper. Alternatively, the body may also be made of other flexible materials, such as polyethylene terephthalate (PET) or a pad. The body may be printed, laminated, and / or include different textures. The body may, for example, be glossy or matte. In one embodiment, the body comprises a laminate containing paper and PET. For example, the body may comprise a paper layer and a polyethylene terephthalate (PET) layer laminated on the paper layer.

[0019] The insect trap of this invention also includes a base. The base includes an illumination element for directing light to the rear surface of a replaceable insert, an electrical contact element for supplying power to the illumination element, and a fastening element for retaining the replaceable insert. In a preferred embodiment, when the insect trap is inserted, for example, into a wall socket, the light is reflected on the rear surface and thus also reaches, for example, the wall opposite the rear surface, which improves the light cues used to attract insects to the insect trap.

[0020] The insect trap according to this invention includes a lighting device as bait to attract insects. The lighting device may use UV light, visible light, or a combination thereof.

[0021] The lighting element may include one or more LEDs and an optional lens.

[0022] Electrical contact elements may include plugs for connecting the base to a wall socket with a power output.

[0023] Alternatively, electrical contact elements can be configured to connect the base to the battery.

[0024] The fastening element may include a slit configured to receive a replaceable insert via a folded edge of a fold line. In this embodiment, the body of the replaceable insert has a folded edge extending along the fold line, which can be easily slid into the slit.

[0025] The method for discarding a used replaceable insert can be as follows. The body of the replaceable insert includes at least one fold line configured to fold the body along the fold line such that at least a portion of the rear surface can be folded onto another portion of the rear surface. The discarding method involves folding said portion of the rear surface onto said other portion of the rear surface such that said portion and said other portion are adhered to each other via an adhesive, thereby enclosing the captured insect between said portion and said other portion. The folded body is then discarded.

[0026] In all embodiments described above and below, the rear surface may include a coated release liner before the replaceable insert is installed in the insect trap to protect the consumer from unwanted contact with the adhesive. The consumer removes the release liner by peeling it off, thus exposing the adhesive and preparing it for insect trapping when the replaceable insert is installed in the insect trap.

[0027] The release liner may include at least one area that remains on the coating when the release liner is removed. When the release liner is removed, such one or more retained areas of the release liner can, for example, serve as finger gripping areas. These areas then constitute adhesive-free areas, thus protecting the consumer's hand from contact with adhesive, for example, when installing or replacing a replaceable insert. Furthermore, these areas may be arranged on the rear surface at portions where the replaceable insert contacts the base of the insect trap to protect the base from contact with adhesive. The release liner with such retained areas can, for example, be manufactured in a process involving a two-stage cutting: partially cutting the peelable contour (i.e., the retained one or more areas) and cutting the outer contour of the replaceable insert.

[0028] Furthermore, in all embodiments described above and below, multiple fold lines (preferably including creases) of the body of the replaceable insert may be arranged at or around the center of the rear surface and / or at regular or varying distances from each other on the rear surface. Preferably, they are arranged around the center of the rear surface at varying distances from each other. Attached Figure Description

[0029] In the following description, embodiments of the present invention are described with reference to the accompanying drawings.

[0030] Figure 1 A contrasting insect trap, including replaceable inserts, is shown in a stereoscopic rear view;

[0031] Figure 2 Shown in front view Figure 1 A comparison of insect traps;

[0032] Figure 3 The interchangeable inserts are shown in comparison; and

[0033] Figure 4 An embodiment of an insect trap according to the present invention is shown. Detailed Implementation

[0034] Figure 1 A contrasting insect trap 101 is depicted. The insect trap 101 is of the type designed to prevent insects from escaping after being captured. To this end, the insect trap 101 includes a replaceable insert 103 having a body 121 having a rear surface 109 with a coating 123.

[0035] The coating 123 includes an adhesive. The adhesive may be a glue used to cause insects to adhere to the rear surface 109 upon contact with it. The insect trap 101 also includes an insect bait in the form of an illumination element 107, which illuminates the rear surface 109 and is adapted to attract insects. UV and / or visible light may be used for this purpose. The illumination element 107 may include one or more LEDs and a lens for directing light to a target area. When the insect trap is inserted into a wall socket, the target area may include a wall opposite the rear surface 109, which may be illuminated by light reflected from the rear surface toward the wall. The insect trap 101 also includes a base 105 having a fastening element 113 for retaining a replaceable insert 103. An electrical contact element 111 is provided to supply power to the illumination element 107. In this embodiment, the electrical contact element 111 includes a plug fitted into a wall socket. The body 121 of the replaceable insert 103 has a fold line 117, along which the body can be folded, such that a portion 109a of the rear surface 109 can be folded onto another portion 109b of the rear surface 109. Figure 1In the comparative insect trap, portions 109a and 109b of the rear surface 109 are consistent / equal, ensuring that the consumer is not exposed to the adhesive after the body 121 is folded. When the captured insect is held onto the rear surface 109 (parts 109a and / or 109b) by the adhesive, the folded portions 109a and 109b of the rear surface 109 adhere to each other via the adhesive and seal the captured insect, thus also preventing the consumer from being exposed to the captured insect. This facilitates the disposal of the replaceable insert 103 when it is depleted and needs to be replaced. Furthermore, the size of the replaceable insert 103 is thus minimized, requiring less space during disposal.

[0036] Figure 2 Depicted in front view Figure 1 Comparative insect trap 101. The body 121 of the replaceable insert 103 has a preferably adhesive-free front surface 119. Alternatively, the front surface 119 may also include a portion covered with adhesive, such that insects contacting the front surface 119 are also trapped there. Figure 2 In the comparative insect trap, the base 105 includes a slit 115 into which a replaceable insert 103 can slide via the folded edge of the fold line 117. The slit 115 facilitates the installation and replacement of the replaceable insert 103.

[0037] exist Figure 3 The image shows a replaceable insert 103 according to another proportional representation. The depicted view is oriented towards the rear surface 109 of the body 121 of the replaceable insert 103. This rear surface 109 has a coating 123 including an adhesive. Figure 3 In the comparative replaceable insert, the body 121 of the replaceable insert 103 has two fold lines 117a and 117b. A portion 109c of the rear surface 109 can be folded onto a portion 109d of the rear surface 109 via fold line 117a, and a portion 109e of the rear surface 109 can be folded onto a portion 109d of the rear surface 109 via fold line 117b. This facilitates the disposal of the replaceable insert 103 after use. Furthermore, in Figure 3In the contrasting replaceable insert, when the body 121 is folded, the consumer is not exposed to insects trapped between portions 109c, 109d, and 109e of the rear surface 109. Furthermore, exposure to adhesive and the size of the folded replaceable insert is minimized. Moreover, the "flanks," namely portions 109c and 109e of the rear surface 109, contribute to increasing the overall size of the rear surface 109, thereby increasing the chance of insect capture. Additionally, the presence of these flanks facilitates manipulation of the body 121 of the replaceable insert 103, as the consumer can grasp the body 121, for example, by placing one hand on the front surface of portion 109c of the rear surface 109 and the other hand on the front surface of portion 109e of the rear surface 109. The front surfaces of portions 109c and 109e of the rear surface 109 are free of adhesive.

[0038] Figure 4 An embodiment of an insect trap 1 according to the present invention is shown. The insect trap has a replaceable insert 3, a support portion for receiving the replaceable insert 3, a fastening element 13, a base 5, an illumination element 7 for providing light cues to attract insects to the insect trap 1, and an electrical contact element 11. The replaceable insert 3 includes a body 21 having a front surface (not shown) and a rear surface 9, on which a coating 23 comprising an adhesive for attracting insects is disposed. The body 21 includes a plurality of fold lines 17a, 17b, 17c, 17d, and 17e. Preferably, the fold lines include creases. Figure 4 In this embodiment, fold lines with creases can be used to create a concave curved shape for the rear surface 9, for example, by slightly bending the rear surface portion adjacent to the corresponding fold lines until the desired total curvature of the rear surface is achieved, without the need for forming tools. The concave curved rear surface region has a larger surface area relative to the width of the insect trap compared to the rear surface of a flat sheet, thus increasing the chance of trapping insects. Additionally, when the insect trap 1 is inserted into a wall socket, light emitted by the illumination element 7 is reflected on the rear surface 9 of the replaceable insert 3 onto the wall opposite the rear surface 9. When the replaceable insert 3 is depleted, the consumer can fold the body along one or more fold lines to create one or more pockets on the rear surface in which insects are trapped. The likelihood of the consumer being exposed to trapped insects and adhesive is thus minimized when the depleted replaceable insert 3 is discarded and replaced.
