Modes for Carrying Out the Invention

[0009] FIG. 1 is a schematic cross-sectional view showing a configuration example of a mite capture body according to the present disclosure. As shown in FIG. 1 for the configuration example of the mite capture body 1 according to the present disclosure, the mite capture body 1 includes a drying sheet 2, two attracting sheets 3 laminated and disposed on both surfaces of the drying sheet 2, and a case 4 that houses the drying sheet 2 and the attracting sheets 3. With such a mite capture body 1, the movement of mites that have entered inside can be slowed down and captured by the effect of the desiccant in the drying sheet 2. Note that in the mite capture body 1 shown in FIG. 1, two attracting sheets 3 are disposed on both surfaces of the drying sheet 2, but even if only one attracting sheet 3 is disposed on only one surface of the drying sheet 2, the same effect can be obtained.

[0010] The drying sheet 2 may be a sheet-like material having the ability to absorb moisture (humidity) in the surroundings. For example, a moisture-proof desiccant (sheet dryer) in the form of a sheet obtained by laminating a film on both sides of a hygroscopic base material can be used. Examples of the hygroscopic base material include a sheet formed of thermoplastic resin fibers or natural pulp and carrying a dry substance such as calcium chloride. In the vicinity of the drying sheet 2, due to its moisture absorption effect, the humidity preferred by mites is reduced, so that the movement of mites approaching the drying sheet 2 can be slowed down.

[0011] The attracting sheet 3 may be a sheet-like material containing an attracting substance 3b for attracting mites. For example, a sheet in which the attracting substance 3b is stored inside a bag body formed of a non-woven fabric 3a can be used. FIG. 2 is a schematic plan view (a) and a schematic cross-sectional view (b) showing a configuration example of an attracting sheet used for the mite capture body according to the present disclosure. As illustrated in FIGS. 2(a) and 2(b), the attracting sheet 3 can be formed by putting the attracting substance 3b inside one or more (six in FIG. 2) bag bodies formed by sewing two non-woven fabrics 3a at the position of a seam 3c. The attracting sheet 3 and the drying sheet 2 are arranged such that there can be a plurality of gaps of about several hundred μm between them and they are not in complete contact with each other. That is, no special treatment such as adhesion is applied between the attracting sheet 3 and the drying sheet 2, and they are overlapped and arranged in a state where they can be easily separated from each other.

[0012] The non-woven fabric 3a is finished in a cloth form by accumulating fibers in a certain direction or randomly, chemically bonding them with an adhesive resin, mechanically entangling them, entangling them with a pressurized water stream, or bonding them with heat-fused fibers. Since there are gaps between the fibers constituting the non-woven fabric 3a, mites can pass through those gaps. The basis weight of the non-woven fabric 3a is preferably 2 30 to 100 g / m 2 more preferably 45 to 80 g / m 2 and can be, for example, 60 g / m

[0013] When the basis weight of the non-woven fabric 3a is within this range, since there are gaps of about 250 to 300 μm between the fibers constituting the non-woven fabric 3a, mites, which are usually about 100 to 200 μm in size, can easily pass through those gaps. In addition, since the non-woven fabric 3a has more freedom of movement of each fiber compared to a woven fabric, even mites larger than the gaps between the fibers can widen the gaps and pass through.

[0014] The non-woven fabric 3a preferably has static electricity. That is, it is preferable to use the non-woven fabric 3a that has been subjected to a process of charging it with static electricity and holding the static electricity for a long time. By using the non-woven fabric 3a having static electricity, fine particles such as mite feces and pollen are adsorbed to the non-woven fabric 3a, so that the captured mites are less likely to go outside.

[0015] As the attractant 3b, for example, diets preferred by mites such as soybean meal, soybean cake, dried yeast, bran, and mite corpses can be mentioned, and those containing fragrances that emit odors preferred by mites, such as fruit fragrance, almond fragrance, and chocolate fragrance, can be mentioned. When using a fragrance that emits an odor preferred by mites, a material in which the fragrance is supported on a base material such as silicon dioxide can be used. The attractant 3b may be in powder form, granular form, flaky form, or crushed form, but preferably has a size such that it does not leak to the outside from the gaps of the non-woven fabric 3a. Mites are attracted by such an attractant 3b and approach the attractant sheet 3, pass through the gaps of the non-woven fabric 3a, and enter the inside of the attractant sheet 3.

[0016] The attractant sheet 3 preferably further contains a desiccant. Since the attractant sheet 3 contains a desiccant, the moisture preferred by mites is reduced inside the attractant sheet 3, so the movement of the mites that have entered the inside of the attractant sheet 3 can be effectively slowed down. In the case of the attractant sheet 3 in which the attractant 3b is stored inside the bag body formed of the non-woven fabric 3a, a desiccant can be put into the inside of 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 to the outside from the gaps of the non-woven fabric 3a.

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

[0018] Such a mite capture body 1 can be installed in places where mites are a concern, such as futons, blankets, mattress pads, mattresses, beds, carpets, tatami mats, floor cushions, cushions, beds, sofas, automobile seat covers, chests of drawers, closets, cabinets, under the floor, etc. The mites around the mite capture body 1 are attracted by the attracting substance 3b and enter the inside of case 4 and the attracting sheet 3. Since the inside of the attracting sheet 3 (particularly in the vicinity of 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 to the 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 without departing from the gist of the present disclosure. For example, the shape of 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. Further, 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.
