Description

  The present invention relates to a mite catching sheet that can efficiently attract and catch mites.

  It is necessary to remove mites that occur in the living environment, such as house mites and pet mites. Some mite catching sheets for the purpose of catching and removing such mites have already been put into practical use, and fragrances or yeast powders derived from plants and animals are used as tick attractants.

For example, the anti-mite sheet of Patent Document 1 discloses an anti-mite sheet provided with an adhesive mite attractant. In this anti-tick sheet, sustained-release microcapsules made of silicon dioxide as a wall material are filled with fruit extract of food additive and fermented with yeast as a tick-inducing agent. I am letting.

In this mite-proof sheet, the attractant is contained in microcapsules, so it is sustained release and long lasting, but it has poor diffusibility, and it may lack the effect of attracting ticks scattered widely, Since the pressure-sensitive adhesive has a tick repellent property, there is a problem that when it is mixed with the attractant, the attractant's mite attracting function is lowered.

The present inventor has proposed a tick-proof capturing sheet improved from the tick-proof sheet disclosed in Patent Document 1 as Patent Document 2.
This anti-mite capturing sheet forms a tick-capturing adhesive layer on the inside of the outer sheet via a polyurethane layer, and it is a protective sheet with a roughness that allows passage of scents but not ticks on part of the adhesive layer. The structure that covers the attractant.

The anti-mite sheet disclosed in Patent Document 3 has a structure in which the inside of the two sheet members is thermally welded to form a hollow portion, and the pressure-sensitive adhesive layer and the mite attracting sheet are accommodated in the hollow portion. In particular, the sheet member is formed of an outer layer and an inner layer, a non-woven fabric containing cotton fibers is used for the outer layer, and polypropylene is used for the inner layer for heat-sealing.

Japanese Patent Laid-Open No. 2002-253103 Japanese Patent No. 51212228 JP2015-202062A

In Patent Document 2 in which the problem of the mite-proof sheet disclosed in Patent Document 1 is solved, a woven fabric made of natural fibers such as cotton is used as the outer sheet, and a polyurethane sheet having air permeability is provided inside the outer sheet. Paste. Moreover, in patent document 3, since the polypropylene layer for heat-welding is provided as an inner layer of a sheet | seat member, tick repellent property is exhibited and the mite capture effect will become weak. Furthermore, in patent document 3, since the adhesive layer is provided in the outer side so that an attracting sheet may be pinched | interposed, there exists a problem that an incentive effect will fall.

  Recent research has shown that mites have the property of avoiding synthetic resins such as polypropylene and polyurethane. Therefore, as in Patent Documents 2 and 3, when a synthetic resin such as polypropylene or polyurethane is superimposed on the attractant, the effect of the attractant is reduced.

  Moreover, in the conventional mite catching sheet, it was thought that the mite was captured exclusively with an adhesive, and the outer sheet and the attractant layer were thought to have no effect of capturing mites. It was found that many mites remained in the natural fiber and attractant layers.

In order to solve the above problems, the mite catching sheet according to the present invention separately accommodates the attractant layer for attracting ticks and the adhesive layer for capturing ticks via a middle sheet in the space formed by the outer sheet. A tick catching sheet, in which only 100% natural fabric was used as the outer sheet and the inner sheet, and the outer sheet and the inner sheet were overlapped and the periphery was sewn with a sewing machine.

  As the structure of the tick catching sheet, the middle sheet is a single sheet, an attractant layer is provided between the middle sheet and one outer sheet, and an adhesive layer is disposed between the middle sheet and the other outer sheet, Alternatively, there are two intermediate sheets, an adhesive layer (or attractant layer) is provided between the two intermediate sheets, and an attractant layer (or adhesive layer) is provided between the intermediate sheet and each outer sheet. Etc. are considered.

Since the tick catching sheet of the present invention uses the tick habit of approaching natural materials and avoiding chemical fibers, the catching effect is greatly improved compared to the conventional one.

In particular, not only natural fabrics are used as the outer and inner sheets, but these sheets are not heat-sealed with synthetic resin, and no chemical fibers are stitched together with a sewing machine, so the mite repellent effect can be suppressed and natural fabrics can be suppressed. Because of the collection of ticks on the seams, the catching effect is enhanced. Cotton cloth is most preferable as the natural fabric.

In particular, when the sheets are sewn together with a sewing machine, the fiber density at the sewn portion increases. Recent research has also shown that ticks prefer the high density parts of natural materials, and sewing the sheets together with the sewing machine keeps the ticks attracted to the high density, further enhancing the capture effect.

The whole perspective view of the tick catching sheet concerning the present invention Cross section of the tick catching sheet 2 is an enlarged view of the main part of FIG. Figure similar to FIG. 2 showing another embodiment

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the mite catching sheet 1 is formed by the inner sheet 3 in the wrapping bag formed by the outer sheet 2 and is divided into two spaces, and one space attracts ticks. An agent layer 4 is provided, and an adhesive layer 5 for capturing mites is provided in the other space.

As the material of the outer sheet 2 and the middle sheet 3, natural fabric is used. Among natural fabrics, cotton was the most effective. In addition to the cotton cloth, silk, hemp, Japanese paper, etc. may be used, or these may be mixed with the cotton cloth. Further, the roughness of the outer sheet 2 is set so that the scent of the attractant is likely to diffuse outside.

Further, the outer sheet 2 and the inner sheet 3 are stitched together with a sewing machine in a state where the attractant layer 4 and the adhesive layer 5 are filled. The sewing thread 6 is also preferably a natural thread such as cotton thread.

The thickness of the stitched portion is reduced, and the fiber density is increased accordingly. It has been discovered that ticks prefer places with high fiber density, and the present inventor has also verified that there is a tendency for ticks on the sewing machine to gather.

As the attractant layer 4, a plant extract fragrance (geranyl propionate), which is a food additive, is impregnated in powdered calcium carbonate, and this powdered calcium carbonate is mixed with powdered dry yeast (beer yeast). This attractant is not dangerous even if a child eats it.

The adhesive layer 5 is for catching attracted ticks. For example, a double-sided adhesive sheet can be used, and the flow of air in the sachet formed by the air-permeable outer sheet 2 is blocked. In order to avoid this, a plurality of pressure-sensitive adhesive sheets may be used.

In the embodiment shown in FIG. 4, two intermediate sheets 3 are provided, an adhesive layer 5 is provided between the intermediate sheets 3, 3, and the intermediate sheet 3 and the outer sheet 2 outside the adhesive layer 5 are provided. It has a three-layer structure in which an attractant layer 4 is provided therebetween.

Since the adhesive layer itself is paste-like (pasted), it is applied to the surface of the intermediate sheet 3 at the time of manufacture, or one having an adhesive layer formed on both surfaces of the substrate in advance is used. Even if a synthetic resin such as polypropylene is used as the base material, the repelling effect is suppressed because both surfaces are covered with the adhesive layer.

By providing the attractant layer 4 on both surfaces in this way, the mite capturing effect is further enhanced. Also in this case, the outer periphery of the sheet is sewn with a sewing machine without being fused, so that mites preferably enter the sheet.

In the embodiment shown in FIG. 4, the adhesive layer 5 is provided between the two middle sheets 3, and the attractant layer 4 is disposed on both outer sides, but the attractant layer 4 is provided between the two middle sheets 3, The adhesive layer 5 may be disposed on both outer sides.

  As described above, the mite catching sheet of the present invention does not repel mites because it does not use any chemical fiber on the outer sheet, has a high tick attracting / capturing effect, and high safety. It can be placed in places where you want to remove ticks, such as living rooms, offices, pet spaces, under carpets and under tatami mats, and you can easily eliminate captured ticks.
