Summary of the Invention

Problems to be Solved by the Invention

[0005] One of the objectives of the present disclosure is to provide a mite capture body capable of easily capturing mites.

Means for Solving the Problems

[0006] The mite capture body according to the present disclosure is a drying sheet, an attracting sheet including an attractant substance for attracting mites, disposed on at least one surface side of the drying sheet, A case for housing the drying sheet and the attracting sheet. It is a mite trapping body that has [the following properties]. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a mite trap capable of easily capturing mites. [Brief explanation of the drawing]

[0008] [Figure 1] This is a schematic cross-sectional view showing an example of the configuration of a mite trap related to this disclosure. [Figure 2] These are schematic plan view (a) and schematic cross-sectional view (b) showing examples of the configuration of the attractant sheet used in the mite trap according to this disclosure. [Figure 3] This is a schematic plan view showing an example of the external configuration of a case used in the mite trap according to this disclosure. [Modes for carrying out the invention]

[0009] Figure 1 is a schematic cross-sectional view showing an example of the configuration of a mite trap according to the present disclosure. As shown in Figure 1, the mite trap 1 according to the present disclosure comprises a drying sheet 2, two attractant sheets 3 arranged in layers on both surfaces of the drying sheet 2, and a case 4 that houses the drying sheet 2 and the attractant sheets 3. With such a mite trap 1, the desiccant in the drying sheet 2 slows down the movement of mites that have entered the interior, allowing for capture. In the mite trap 1 shown in Figure 1, two attractant sheets 3 are arranged on both surfaces of the drying sheet 2, but a similar effect can be obtained even if only one attractant sheet 3 is arranged on one surface of the drying sheet 2.

[0010] The drying sheet 2 can be any sheet-like material that has the ability to absorb surrounding moisture (humidity). For example, a sheet-like moisture-proof desiccant (sheet dryer) made by laminating a hygroscopic base material with film on both sides can be used. Examples of hygroscopic base materials include sheets made of thermoplastic resin fibers or natural pulp on which a drying substance such as calcium chloride is supported. Due to its moisture-absorbing effect, the area near the drying sheet 2 has less moisture that mites prefer, thus slowing down the movement of mites that approach the drying sheet 2.

[0011] The attractant sheet 3 can be any sheet containing an attractant substance 3b for attracting mites. For example, a sheet can be used in which the attractant substance 3b is stored inside a bag made of nonwoven fabric 3a. Figure 2 is a schematic plan view (a) and a schematic cross-sectional view (b) showing an example of the configuration of an attractant sheet used in a mite trap according to the present disclosure. As illustrated in Figures 2(a) and (b), the attractant sheet 3 can be formed by placing the attractant substance 3b inside one or more (six in Figure 2) bags formed by sewing two nonwoven fabrics 3a together at the seam 3c. The attractant sheet 3 and the drying sheet 2 are arranged so that they are not in complete contact with each other, and there may be several gaps of several hundred μm between them. That is, the attractant sheet 3 and the drying sheet 2 are not treated with any special adhesive, and are placed on top of each other in a state where they can be easily separated.

[0012] Nonwoven fabric 3a is made by accumulating fibers in a specific direction or randomly, and then chemically bonding them with adhesive resin, mechanically entangling them, entangling them with a pressurized water stream, or bonding them with heat-fusible fibers to create a fabric-like material. Because gaps exist between the fibers that make up nonwoven fabric 3a, mites can pass through these gaps. The basis weight of nonwoven fabric 3a is 30-100 g / m². 2 Preferably, it is 45-80 g / m 2 It is more preferable that it be 60 g / m² 2This can be achieved. If the basis weight of the nonwoven fabric 3a is within this range, there will be gaps of about 250 to 300 μm between the fibers that make up the nonwoven fabric 3a, so mites, which are usually about 100 to 200 μm in size, can easily pass through these gaps. Furthermore, since the nonwoven fabric 3a has more freedom of movement for each fiber compared to woven fabric, even mites larger than the gaps between the fibers can widen the gaps and pass through.

[0013] The color of the nonwoven fabric 3a can be chosen based on design considerations, but black is preferable because mites prefer dark places. Also, since captured mites appear as a white powder, a black nonwoven fabric 3a makes it easier to check the mite capture status.

[0014] It is preferable that the nonwoven fabric 3a is electrically charged. That is, it is preferable to use a nonwoven fabric 3a that has been treated to be electrically charged and retained for a long period of time. By using an electrically charged nonwoven fabric 3a, fine particles such as mite feces and pollen are attracted to the nonwoven fabric 3a, making it more difficult for captured mites to escape to the outside.

[0015] Examples of attractant substances 3b include mites' preferred food sources such as soybean meal, soybean meal, dried yeast, wheat bran, and dead mites, and containing fragrances that emit odors that mites like, such as fruit flavors, almond flavors, and chocolate flavors. When using fragrances that emit odors that mites like, a material can be used in which the fragrance is supported on a base material such as silicon dioxide. The attractant substance 3b may be in powder form, granular form, flaky form, or crushed form, but it is preferable that it be large enough so that it does not leak out of the gaps in the nonwoven fabric 3a. Mites are attracted by such attractant substances 3b and approach the attractant sheet 3, pass through the gaps in the nonwoven fabric 3a, and enter the inside of the attractant sheet 3.

[0016] The attracting sheet 3 preferably further contains a desiccant. Since the attracting sheet 3 contains a desiccant, the moisture preferred by mites is reduced inside the attracting sheet 3, so that the movement of mites that have entered the inside of the attracting sheet 3 can be effectively slowed down. In the case of the attracting sheet 3 in which the attracting substance 3b is stored inside the bag body formed of the non-woven fabric 3a, a desiccant can be put inside the bag body. Examples of the desiccant include silica gel, quicklime, calcium chloride, etc. The desiccant may be in powder form, granular form, flaky form, or crushed form, but preferably has a size such that it does not leak outside through the gaps of the non-woven fabric 3a.

[0017] The case 4 may be any that can accommodate the drying sheet 2 and the attracting sheet 3 by overlapping them. FIG. 3 is a schematic plan view showing an example of the external configuration of the case used for the mite capturing body according to the present disclosure. As illustrated in FIG. 3, the case 4 can use a bag body having an opening through which the drying sheet 2 and the attracting sheet 3 can be inserted from above. In this case, the opening can be closed by the folding part 4b. The case 4 may be made of plastic, paper, or cloth. A plurality of holes 4a are provided on the surface of the case 4 (particularly the surface on the side where the attracting sheet 3 is arranged) and are configured in a grid pattern. By doing so, mites can enter the inside of the case 4 through the holes 4a. Also, by making the surface of the case 4 into a grid pattern, the light from the outside can be blocked by the portions other than the holes 4a, and the inside of the case 4 can be made as dark as possible. Furthermore, by providing a display part 4c on the surface of the case 4, for example, the start date of use can be filled in. Note that the drying sheet 2 and the attracting sheet 3 may simply be arranged by overlapping them.

[0018] Such a mite capture body 1 can be installed in places where mites are a concern, such as futons, blankets, sheets, mattresses, beds, carpets, tatami mats, cushions, beds, sofas, automobile seat covers, chests of drawers, wardrobes, closets, under the floor, etc. Mites around the mite capture body 1 are attracted by the attractant 3b and enter the case 4 and the inside of the attracting sheet 3. Since the inside of the attracting sheet 3 (especially near the drying sheet 2) has less moisture due to the moisture absorption effect of the drying sheet 2, the movement of the mites that have entered the inside of the attracting sheet 3 becomes sluggish. The mites with sluggish movement are trapped inside the attracting sheet 3 or in the gap between the attracting sheet 3 and the drying sheet 2, making it difficult for them to escape outside. The mite capture body 1 that has captured mites can be discarded as it is.

[0019] As described above, the embodiments of the mite capture body according to the present disclosure have been specifically described. However, the present disclosure is not limited to the above-described embodiments and can be appropriately modified within the scope not departing from the gist of the present disclosure. For example, the shape of the case 4 is not limited to the above embodiment, and the arrangement state of the holes 4a does not necessarily have to be configured in a lattice pattern. That is, it is sufficient that there are holes (openings) through which mites can enter. Also, in the above embodiment, the sizes (planar view areas) of the drying sheet 2 and each attracting sheet 3 were made approximately the same, but the relative relationship between the sizes of the two is not limited to the above description.
