JP2001354503A - Sheet for detecting and catching mite and tick - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a sheet for detecting and catching mites and ticks, capable of easily detecting and controlling the mites and ticks which can not be easily recognized by the naked eyes because the mites and ticks have very small bodies and usually lurk in the inner parts of a Tatami mat (mat made of rush for Japanese life) or a carpet, and cause allergy. SOLUTION: This sheet for detecting and catching the mites and ticks is composed of a colorless transparent sheet 1, an open-pore porous body layer 4 colored to a dark deep color to facilitate the detection of the caught white mites and ticks, and having a three-dimensional structure into which the mites and ticks can easily invade but dust and dirt cannot easily enter to a adhesive layer, and the adhesive layer 2 including a transparent adhesive for sticking the mites and ticks, or an attractant, or an attractant-impregnated sheet 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mite capturing sheet which can easily detect, capture and confirm mites that live in a room or the like that adversely affects health.

[0002]

2. Description of the Related Art In recent years, an environment favorable to the inhabitation of ticks in the house has been created by improving the airtightness of a house environment, in particular, indoor airtightness, and the spread of heating equipment. Accompanying this, problems with the occurrence and proliferation of mites have been occurring for a longer period of time than in the past.

[0003] A problem caused by mites is a health hazard such as asthma or atopic dermatitis caused by allergens such as mite dung and carcasses. Many people are bothered by this disease, and measures against mites are great. It is a problem.
The mites that cause such problems prefer small, narrow, dark, humid places, and are usually hidden behind tatami or carpets, making it impossible to see them with the naked eye.

[0004] As a method for detecting the presence of a tick, and confirming the capture, a method of impregnating an adhesive with a tick attractant or a color former which reacts with a protein of a body fluid of the tick to form a color and confirms the color of the mite attracted and captured. However, there is a problem that human dandruff, detached epidermis, and food debris are also colored.

[0005] Further, a spacer having a large number of holes on the lower surface of a sheet to which an adhesive or an attractant is attached, a capture sheet comprising a nonwoven fabric or a non-contact member between the nonwoven fabric and the adhesive, or an adhesive sheet for preventing dust from adhering. A technique is disclosed in a patent in which a case is provided and a large number of small holes are provided on the upper surface of the case so that ticks enter the adhesive sheet. In these techniques, only the capture of mites is considered, and no technique is disclosed for confirming the effect of whether or not they have been captured.

Further, since the thickness of the fiber of the carpet is considerably smaller than the size of the hole of the spacer, the fiber easily adheres to the adhesive of the pressure-sensitive adhesive sheet through the hole of the spacer. There is a problem that requires the intervention of the body.

[0007] If a hole is provided on the upper surface of the case for dust mites, the amount of dust and dust falling from above is larger,
They accumulate in a short time and close the hole, fine dust enters from the hole, adheres to the adhesive, and the tick has to climb up the case to get inside the case, There is a troublesome problem that the trapping efficiency of the mites must be reduced or the trap sheet must be replaced one by one.

[0008] Further, in order to make it easier to confirm the captured mites, a technique of coloring the adhesive in a dark and dark color has also been disclosed. There is a problem that it becomes worse and hard to see.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to propose a tick detection and capture sheet which can effectively and easily detect and capture mites by improving the drawbacks of the prior art.

[0010]

Means for Solving the Problems The present inventors have conducted various studies on the above problems, and have reached the present invention. That is, the present invention provides a transparent sheet or film layer, an adhesive layer,
It is a tick detection and capture sheet composed of a continuous porous layer colored dark and dark.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the tick detection and capture sheet of the present invention will be described below with reference to the drawings. FIG.
FIG. 2 is a schematic perspective view of a tick detection and capture sheet, FIG. 2 is an enlarged cross-sectional view of the tick detection and capture device, 1 is a transparent film or sheet layer,
2 is an adhesive or attractant impregnated layer, 3 is an attractant impregnated sheet,
4 is a foam (continuous porous) layer. It should be noted that the above-mentioned mite detection and capture sheet is not limited to this in one embodiment of the present invention.

The sheet or film used in the present invention comprises:
Transparent so that trapped mites can be easily detected, and placed on burrows, tatami mats, floors, etc. Any material can be used as long as it is a little flexible and colorless.

[0013] As an adhesive for the adhesive layer, a sheet or film layer and a continuous porous layer can be adhered,
In addition, in order to make it easier to confirm the mites captured from the sheet surface with little effect on the attraction and capture of mites, it is preferable to use a colorless and transparent material as much as possible, and a rubber-based adhesive is particularly preferable. An adhesive layer may be formed on the transparent sheet or film.

A continuous porous layer having a three-dimensional skeletal structure is
Small holes that allow ticks to enter and exit freely are connected continuously in a three-dimensional mesh network, and ticks that have entered through the holes in the continuous porous material layer from the tatami, carpet, floor are continuous. It climbs along the skeleton of the porous layer and is easily captured by the adhesive of the adhesive layer on the upper side.

It is preferable that the white mite is colored dark dark so that it can be easily visually identified.
Because it is placed on the floor etc., it is durable and will not break even if it is stepped on with your feet, and will not be deteriorated by the adhesive of the adhesive layer, for example,
Wood, ceramics, natural materials, synthetic resins, and composites thereof are conceivable, and any material having a little flexibility is preferable.

As a continuous porous body having such a structure and function, a foamed sponge, for example, a foamed body (sponge) such as polyurethane, polyethylene (PE), PVC, or PVA
And the like are preferable, but not limited thereto. What is easily available among foams, in particular, a polyurethane type sponge is preferable, and further, an open cell type foam sponge in which each cell of the foam is completely three-dimensionally connected to each other is particularly preferable. preferable.

As this type, there is a hot-pressed polyurethane sponge or Everlite SF (trade name, manufactured by Bridgestone Corporation). This SF is available in different types of products having different sizes of holes (cells) (number of cells per unit length). This Everlight SF is colored black, and this black color has a clear contrast with the white color of the mites captured by the adhesive, which is convenient because it is easy to detect the mites.

Since Everlight SF is also used as a filter for air purifiers, dust and dirt from the air and carpet hardly enter, so that dust and dirt do not adhere to the adhesive, and detection of ticks is ensured. And preferred. Further, since the size of the holes of the Everlight SF is not uniform to some extent, the mites are attracted by the attractant, and enter the small holes on the way before being captured by the adhesive, and are captured.

If it escapes after being captured from the adhesive, there is a high possibility that it will be captured in a small hole on the way, and it has a role as a physical capture sheet for mites, and also has an Everlite SF.
Because the three-dimensional skeleton has a solid structure, the holes it creates are compressed as in the case of gaps woven with fine fibers of cloth or non-woven fabric, almost crushing the mite entry holes. There is no danger that the fibers will not adhere to the adhesive layer and catch mites.

Further, the SF has a role of a spacer for preventing the pressure-sensitive adhesive of the pressure-sensitive adhesive sheet from adhering to the carpet, and serves to prevent dust,
It is also a very useful material that acts as a filter to prevent dust from adhering. Among the types of Everlight SF, HR-2
0 (17-23 cells per 2.5 cm), HR-
The pore size of 30 (27 to 33) and HR-40 (37 to 43) is preferable because the mites easily enter, dust does not easily enter, and dust and dust do not adhere to the adhesive. The thickness is 1
2 mm or more is preferable.

It is preferable to use an attractant for attracting ticks in order to enhance the effect of capturing mites. The attractant for ticks is not particularly limited as long as it can attract ticks. Agents and pheromone attractants can be used. Dietary attractants include, for example, dry yeast, powdered feed, daphnia and their extracts, and it has been reported that some flavor components have an attractive effect.
The tick attractant may be mixed with the pressure-sensitive adhesive of the adhesive layer, or when the compatibility with the pressure-sensitive adhesive is poor, the impregnated body may be adhered to the pressure-sensitive adhesive.

[0022]

The tick detection and capture sheet of the present invention is obtained by bonding a transparent sheet or film on the upper surface and a porous material layer for easily invading the mites on the lower surface but preventing dust and dust from entering the adhesive layer, Further, it is composed of an adhesive layer provided with an adhesive for attracting and attracting mites and an attractant. When the tick detection capturing sheet is placed on a tatami mat, carpet, or floor, the mites enter the colored porous layer, are attracted by the attractant, go up along the holes, and are captured by the adhesive. The captured white mites are adhesive, the top sheet is transparent, and the lower part of the adhesive is a colored porous layer, so that the tick detection and capture status can be easily and always visually checked,
The tick detection and capture sheet can be used efficiently and effectively.
