Description

The present invention relates to a mite capture sheet that captures mites that propagate on futons, blankets, mattresses, rugs, mattresses, tatami mats, rugs, sofas, cushions, automobile seats and the like.

Traditionally, mites have been repelled as harmful animals to the human body, but in recent years, the housing environment, especially the improvement of indoor airtightness and the spread of heating equipment, has increased the number of environments that are convenient for mites to live in, and mites have become more common. It is easy to breed.
In addition to the damage caused by ticks directly biting the skin and causing itching and swelling, the dead mites and feces become house dust floating in the indoor air, which becomes an allergen and causes allergic diseases and bronchial asthma. It contributes to the increase of such respiratory diseases.
Mites, which are pests, are small in length and lurking in fibers such as duvets, blankets, and carpets, so their existence cannot be confirmed with the naked eye.

A capture sheet type mite-proof product that holds mites with an adhesive sheet or the like for the purpose of reducing mites is known.
The mite-proof sheet described in Japanese Patent Publication No. 3-67588 is a mixture of a dietary and odorous mite attractant and a mite-killing agent sprayed or coated on a sheet such as a non-woven fabric, and the surface of the sheet. It is a tick-proof sheet with gauze attached to it.

Jitsukaihei 3-67588 Gazette Japanese Unexamined Patent Publication No. 7-327573 Japanese Patent Application Laid-Open No. 2002-253103 Jikkai Sho 64-56677

The tick-proof sheet described in Japanese Patent Application Laid-Open No. 3-67588 is non-adhesive because the fiber itself is adhered to the adhesive surface and covers the adhesive tape because the textile product is attached to the surface of the adhesive tape. The part is narrow, and only the ticks that have passed through the adhesive part are adhered and captured, and the capture efficiency is poor.
Further, the mite-proof sheet described in Japanese Patent Application Laid-Open No. 3-67588 is only covered with gauze, and various dusts and dusts easily adhere to the surface of the adhesive, and dusts and dusts adhere to the surface of the adhesive. In that case, the probability that the mites would be caught by touching the adhesive was even lower, and it was not possible to actually catch the mites.

Next, in the tick-proof sheet described in Japanese Patent Application Laid-Open No. 7-327573 of Patent Document 2, a fibrous material such as gauze is not directly placed on the adhesive sheet, and a frame-shaped covering member is slightly above. However, there are the following problems.
The first problem is that the adhesive strength of the adhesive sheet decreases quickly.
Since the tick-proof sheet described in JP-A-7-327573 is provided with a frame-shaped covering member above the adhesive sheet, the adhesive sheet is exposed immediately inside the frame, so to speak. When installed on bedding such as futons and blankets with a lot of mites, the problem is that if the adhesive surface is exposed, the adhesiveness due to dust will decrease.
The second problem is the escape of mites once caught.
In order to improve the rate of catching mites, the problem is how to increase the frequency of contact between mites and the adhesive sheet and how the adhesive sheet can capture a part of the body. Since mites walk around with their thin legs, even if a part of their legs touches the adhesive sheet, they may break away from it and escape. Coupled with the first problem, when the adhesive strength of the adhesive sheet weakens, it is expected that many mites will escape from the adhesive sheet and escape.

Next, since the tick-proof sheet described in Japanese Patent Application Laid-Open No. 2002-253103 of Patent Document 3 is provided with a porous covering member above the adhesive sheet, it is referred to in Japanese Patent Application Laid-Open No. 7-327573 of Patent Document 2. It can be said that the dust and the like scattered on the adhesive sheet can be captured by the mesh-like clothing member from the described anti-tick sheet, the adhesive surface is less likely to be covered with dust and the like, and the decrease in adhesiveness is relatively small. However, the adhesive sheet is made by applying an adhesive on a support member such as paper to make an adhesive sheet, and when the tick passes through the mesh-like covering member and reaches the adhesive sheet, the tick is from the foot. It is thought that the adhesive sheet will be touched more often, but since the surface of the adhesive sheet is flat, the ticks will detect the adhesive while the force to catch the thin foot touched earlier is still weak, and at that point. Since the remaining legs of the eight legs still firmly grip the porous clothing member, they may be able to exert sufficient force to pull off the legs that have been caught and stuck, and escaped and escaped. There is a risk that it will end up.

Next, since the tick-proof sheet described in Japanese Patent Application Laid-Open No. 64-56677 of Patent Document 4 is provided with a mesh-like covering member above the adhesive sheet, Japanese Patent Application Laid-Open No. 7-327573 of Patent Document 2 is provided. Since the dust and the like scattered on the adhesive sheet can be captured by the mesh-like covering member from the tick-proof sheet described in the above, the adhesive surface is less likely to be covered with dust and the like, and it can be said that the decrease in adhesiveness is relatively small. However, the adhesive sheet is made by applying an adhesive on a support member such as paper to make an adhesive sheet, and when the tick passes through the mesh-like covering member and reaches the adhesive sheet, the tick is from the foot. It is thought that the adhesive sheet will be touched more often, but as in Patent Document 3 described above, since the surface of the adhesive sheet is flat, the tick adheres while the force to catch the thin foot touched earlier is still weak. At that time, the remaining legs of the eight legs still firmly grip the mesh-like covering member. In some cases, the pulling force can be fully exerted, and there is a risk of detaching and escaping.

In order to solve the above-mentioned problems, the present invention allows the mites once captured by the components exhibiting the adhesive force to be detached while preventing the components exhibiting the adhesive force from decreasing without exposing the components exhibiting the adhesive force to the mites. The purpose is to provide a three-dimensional mite catcher that cannot escape.

The three-dimensional mite catcher of the present invention has a three-dimensional structure having a pore size through which ticks can pass, and a three-dimensional structure adhesive formed by impregnating the inside of the three-dimensional structure with a pressure-sensitive adhesive for catching ticks. It is a three-dimensional mite catcher provided with a layer, and the mite that has entered the inside from the outer surface of the three-dimensional structure is captured by the three-dimensional structure adhesive layer.

Here, the above-mentioned three-dimensional structure adhesive layer is formed by impregnating a material of a three-dimensional structure with an adhesive.
The three-dimensional structure adhesive layer is not exposed on the outer surface of the three-dimensional structure, and the three-dimensional structure adhesive layer is formed until a part of the body of the tick is captured by the adhesive of the three-dimensional structure adhesive layer and becomes immobile. It is preferable to let it penetrate inside. Then, in the three-dimensional mesh structure, the back and the torso are caught by the thread-like wall surfaces and pillars forming the mesh, and they can no longer move by foot, and escape is impossible.
The three-dimensional mite catcher of the present invention may be installed simply by placing it, but it is also possible to attach it to the installation location. In that case, if the adhesive for sticking or the above-mentioned adhesive is applied to one surface of the three-dimensional structure, it can be pasted and attached to the installation location from the one side.

Here, as the three-dimensional structure, there is a porous body of a sponge-like open cell structure. The pore size of the open cell structure is preferably 300 to 3000 μm. The main mites that survive in bedding are house dust mites, Tyrophagus putrescentiae, and house dust mites. To catch these mites, the body length of the mites is about 100 μm for larvae and about 300 μm to 500 μm for adults. An appropriate size of 300 to 3000 μm is suitable for adults to invade without difficulty.
Further, for example, as a three-dimensional structure, there is a mesh structure of a mesh-like continuous lattice structure.
The three-dimensional structure adhesive layer is an adhesive layer having a three-dimensional structure.
Since the three-dimensional structure is a porous body of a sponge-like open cell structure or a mesh structure of a mesh-like continuous lattice structure, an adhesive layer having a three-dimensional structure can be formed by impregnating it with an adhesive. .. That is, the three-dimensional structure adhesive layer forming the core of the three-dimensional tick trap of the present invention is a sponge-like open cell structure or a mesh-like continuous lattice structure, and the structure as the skeleton has adhesiveness. , It will be a tick catching structure that has never existed before.

First, the adhesive area of the three-dimensional structural adhesive layer is dramatically increased as compared with the conventional tick-proof sheet. Since the conventional tick-proof sheet has only a single-layer adhesive surface, the adhesive area is only the area of the adhesive surface. On the other hand, in the three-dimensional tick trap of the present invention, the three-dimensional structure adhesive layer is a sponge-like open cell structure or a mesh-like continuous lattice structure, and the structure as the skeleton has adhesiveness, so that the area thereof. Is increasing dramatically in three dimensions.

Next, since a large number of gaps of about 300 to 3000 μm are formed in the three-dimensional structure adhesive layer, a part of the body of the mite is trapped by the adhesive and penetrates into the inside of the three-dimensional structure adhesive layer until it becomes immobile. It becomes possible. Then, the parts such as the back, body side, and head other than the feet of the mites are so sticky that the mites that have invaded the inside of the three-dimensional structure adhesive layer try to turn back or walk around. It touches the structure that forms the skeleton of the layer, and the relevant part other than the foot is captured and becomes immobile.

As described above, the three-dimensional mite catcher of the present invention is different from the conventional mite-proof sheet, and clearly has an improved adhesive area and can catch mites three-dimensionally. It has become.

If the three-dimensional structure adhesive layer contains a mite attracting bait, the mites are attracted to the inside of the three-dimensional structure adhesive layer, and it becomes easy to catch the mites.
As the mite attracting bait, one containing any one of dried yeast, fusuma, mite carcass or a combination thereof is preferable. They are a favorite of mites that tend to attract mites, and mites are more likely to be caught.

Hereinafter, embodiments of the three-dimensional mite catcher of the present invention will be described. The following embodiments are merely examples and do not limit the technical scope of the present invention.

Hereinafter, a configuration example of the three-dimensional mite catcher of the present invention will be described.
FIG. 1 is a very simple illustration of the structure of the three-dimensional mite catcher of the present invention.
FIG. 1A is a perspective view of a three-dimensional mite catcher 100, and FIG. 1B is a schematic enlarged view of a three-dimensional structure 110 and a three-dimensional structure adhesive layer 120. It is shown very simply for clarity.
As seen in FIG. 1, the three-dimensional mite catcher 100 of the present invention includes a three-dimensional structure 110a and 110b and a three-dimensional structure adhesive layer 120 sandwiched between the three-dimensional structures 110a and 110b. It is composed.

The three-dimensional structures 110a and 110b are structures having pore diameters through which ticks can pass, are located on the front and back sides of the three-dimensional structure adhesive layer 120, allow ticks to pass inside, and have a three-dimensional structure. It has a role of preventing the adhesive layer 120 from being exposed.

In this example, the three-dimensional structures 110a and 110b are porous bodies of a sponge-like open cell structure.
For example, the pore diameter of the bubbles in the open cell structure is preferably 300 to 3000 μm. The main mites are house dust mites, Tyrophagus putrescentiae, and dust mites, and these mites are adults and are about 300 μm to 500 μm. An appropriate pore size of 300 to 3000 μm is suitable for these adults to easily invade.
As the material of the porous body, there are various materials such as urethane foam, rubber foaming agent foam, melamine foam, and EVA sponge foam. Other materials may be used as long as they have a foaming performance that can form a porous body having an appropriate open cell structure.

The three-dimensional structure adhesive layer 120 is a three-dimensional structure adhesive layer provided inside the three-dimensional structure for capturing mites, and is sandwiched between the three-dimensional structures 110a and 110b. That is, as shown in FIG. 1, the three-dimensional structure adhesive layer 120 for capturing mites is formed inside the three-dimensional structure without being exposed on the outer surface.

For example, the three-dimensional structure adhesive layer 120 is formed by impregnating the materials of the three-dimensional structures 110a and 110b with an adhesive. Since the three-dimensional structures 110a and 110b are porous bodies having a sponge-like open cell structure, a pressure-sensitive adhesive layer having a three-dimensional structure can be formed by impregnating the three-dimensional structures 110a and 110b with a pressure-sensitive adhesive. That is, the three-dimensional structure adhesive layer 120 is an open cell structure in which bubbles of about 300 to 3000 μm are connected, and the structure itself as the skeleton has adhesiveness.

The pressure-sensitive adhesive may be an emulsion type pressure-sensitive adhesive or a hot-melt type pressure-sensitive adhesive.

The material of the three-dimensional structures 110a and 110b is impregnated with such an adhesive 12. If the amount of impregnation is too small, the effect is small, and if it is too large, the meshes of the three-dimensional structures 110a and 110b are crushed by the adhesive, and the three-dimensional network-like structure cannot be maintained. Therefore, the impregnation amount should be such that it spreads over the wall surface of the three-dimensional mesh-like structure such as urethane and the pillar itself, but does not fill the gaps between the squares. For example, the impregnation amount is in the range of 10 to 200 g / m2, and as an example, it is 100 g / m2.

Regarding the viscosity of the adhesive, it is necessary to stay in a three-dimensional mesh-like structure such as urethane, so if it is too low, it may flow out, and if it is too large, it will be difficult to apply it and the three-dimensional structure adhesive layer. It becomes difficult for the adhesive layer to spread evenly over the entire 120. Therefore, the viscosity is set to a viscosity suitable for coating so that it does not easily flow out from the three-dimensional network-like structure.

The pressure-sensitive adhesive may be applied by any coating method, and for example, the pressure-sensitive adhesive can be applied by using a printing technique in the same manner as silk screen printing. That is, the adhesive is treated as silk screen ink and uniformly applied to the surfaces of the three-dimensional structures 110a and 110b in the manner of printing.
In this case, the method for manufacturing the three-dimensional structure adhesive layer 120 is to press the three-dimensional structure 110a and the three-dimensional structure 110b on which the adhesive is printed on the surface and bond them together to produce the three-dimensional structure adhesive layer 120. do.
Further, as a coating method, instead of silk screen printing, a method of continuously coating the roll-shaped three-dimensional structure 110a and the three-dimensional structure 110b using a roller may be possible.

The adhesive area of the three-dimensional structural adhesive layer 120 is dramatically increased as compared with the conventional tick-proof sheet. In this example, the three-dimensional structure adhesive layer 120 is a sponge-like open cell structure, so to speak, a three-dimensional network structure, and the structure as the skeleton has adhesiveness, so that the area is dramatically increased three-dimensionally. is doing.
Further, as described above, the three-dimensional structure adhesive layer 120 has a large number of gaps of about 300 to 3000 μm formed in the three-dimensional structure adhesive layer 120, so that a part of the body of the tick is captured by the adhesive. It has a structure that allows it to penetrate inside the three-dimensional structure adhesive layer until it becomes immobile.

The three-dimensional structural adhesive layer 120 contains a mite attracting bait.
For example, it may contain any one of dried yeast, fusuma, carcass of mites, or a combination thereof. Carcasses of mites are foods that take advantage of the cannibalistic nature of mites.
Since the three-dimensional structure adhesive layer 120 contains the attracting bait, the mites are attracted toward the three-dimensional structure adhesive layer 120.
The above is a description of the configuration of each part of the three-dimensional mite catcher 100 of the present invention.

FIG. 2 is a diagram illustrating a flow of mite capture when the three-dimensional mite catcher 100 of the present invention is used.
The three-dimensional mite catcher 100 of the present invention can be used anywhere in which mites are expected to inhabit, such as futons, blankets, floor coverings, rugs, mattresses, tatami mats, rugs, sofas, cushions, and automobile seats. Can be installed.

When the three-dimensional structures 110a and 110b on the front surface or the back surface of the three-dimensional mite catcher 100 of the present invention are not provided with the adhesive, they may be simply placed without being attached.
In addition to the configuration shown in FIG. 1, when a sticking adhesive or the above-mentioned adhesive is separately applied to the surface of the three-dimensional structure 110b, which is the inner surface of the three-dimensional mite catcher 100, 3 is applied to the installation location. It is also possible to attach from the dimensional structure 110b side.

Many mites live in the installation site and are moving around.
Since the three-dimensional structure adhesive layer 120 contains the attracting bait, the mites are attracted toward the three-dimensional structure adhesive layer 120.
The mites first attach to the surfaces of the three-dimensional structures 110a and 110b on the front surface or the back surface of the three-dimensional mite catcher 100, and further invade the inside from the surfaces of the three-dimensional structures 110a and 110b.
As described above, the three-dimensional structures 110a and 110b are open cell structures in which bubbles of about 300 to 3000 μm are continuous, so that they can enter the inside of the three-dimensional structures 110a and 110b through the gaps. Is.

Since the three-dimensional structures 110a and 110b are open-cell structures, they are easy for mites to enter, and the temperature and humidity are appropriate, so that they originally provide an environment in which mites prefer to stay.
Eventually, the mites pass through the three-dimensional structures 110a and 110b and reach the three-dimensional structure adhesive layer 120.
The tick reaches the three-dimensional structure adhesive layer 120, but since the three-dimensional structure adhesive layer 120 also has an open cell structure similar to the three-dimensional structures 110a and 110b, it is caught by the adhesive and cannot move. , It is possible to continue to invade the inside of the three-dimensional structure adhesive layer 120.

Then, while the mites that have invaded the inside of the three-dimensional structure adhesive layer 120 are walking around and trying to turn back again, parts other than the mites' feet, such as the back, body side, and head, become sticky. The three-dimensional structure that you have touches the structure that forms the skeleton of the adhesive layer, and the relevant part other than the foot is captured and becomes immobile.
The conventional tick-proof sheet is flat and only catches the tick's foot, and the foot catching is a small part of the whole body, and the tick may eventually escape and escape, but the three-dimensional tick of the present invention Since the trap 100 has a structure in which the adhesive is three-dimensionally impregnated in all directions with respect to the ticks that have invaded the inside of the three-dimensional structure adhesive layer 120, the trap 100 is captured by the adhesive from all directions. Is possible. In particular, when the back of the tick is caught by the adhesive, the sticky area is large, and the feet are in the air, and the tension is not effective. Remains captured until it dies.

FIG. 2B shows an enlarged part of the three-dimensional structure adhesive layer 120, and the back and body of the mite are caught by a part of the open cell body of the three-dimensional structure adhesive layer 120 and become immobile. It is a figure which shows briefly. When the back and body of the tick are attracted to a part of the open air bubbles of the three-dimensional structure adhesive layer 120, the feet are in the air of the air bubbles, and the so-called foot is in a situation where it cannot escape even if it rattles.
The above is the description of the flow of mite capture when the three-dimensional mite catcher 100 of the present invention is used.

In the above description, the structures of the three-dimensional structures 110a and 110b and the three-dimensional structure adhesive layer 120 have been described as the porous body of the open cell structure, but the mesh structure of the mesh-like continuous lattice structure is used. The same is true if there is one.
The mesh-like continuous lattice structure has a more regular three-dimensional structure than the porous body of the open-cell structure, but if the mesh size is adjusted to create a three-dimensional structure with a mesh diameter of 300 to 3000 μm, 3 The three-dimensional structures 110a and 110b are formed, and when impregnated with an adhesive, the three-dimensional structure adhesive layer 120 is obtained.

A prototype of the three-dimensional mite catcher 100 of the present invention was produced, and the effect of catching was confirmed by attracting actual mites. As a comparison, we also made a prototype of a conventional product in the form of a conventional adhesive sheet, and confirmed the difference in the effect of capturing by attracting actual mites.

FIG. 3 is a diagram showing a prototype of the three-dimensional mite catcher 100 of the present invention and the state of the mite being supplemented.
Urethane was used as the material. The pressure-sensitive adhesive was selected from acrylic ester polymers and used.
FIG. 3 (a) is a close-up photograph so that the whole picture can be seen, and FIG. 3 (b) is an enlarged photograph showing the three-dimensional network structure of the open cell body of the three-dimensional structure adhesive layer 120 and the mites captured in the structure. Is. The magnification is 50 times.

As shown in FIG. 3B, in the three-dimensional network structure of the three-dimensional structure adhesive layer 120, filamentous ones run in various directions at the micro level to form a three-dimensional network structure, and the filamentous structure is formed. A lot of ticks are stuck to things, so to speak, "bells". Some mites have died and some have not yet died, but in any case, even with their fluttering legs, they can no longer move and remain trapped on the spot.

On the other hand, FIG. 4 corresponds to a prototype conventional adhesive sheet. The surface is two-dimensionally uniform, and an adhesive is applied on it.
The base material was a slide, and an adhesive was applied on it. The pressure-sensitive adhesive was selected from those of the same acrylic ester polymer and used.

FIG. 4 (a) is a close-up photograph so that the whole picture can be seen, and FIG. 4 (b) is an enlarged photograph of a tick on the photograph. The magnification is 50 times.
Looking at FIG. 4A, it can be seen that many mites are riding around. At first glance, it seems that the mites have been successfully captured because the movement of the mites is difficult to understand in the photo, but the mites are only approaching due to the effect of attracting food, and in fact Is moving around on the two-dimensional sheet, so it cannot be said that it is in a captured state.

Looking at FIG. 4 (b), many mites are walking on the two-dimensional sheet, and none of them have their backs or torso captured by the adhesive. Some mites are not moving, but many seem to be just resting.

As described above, when the mite capture effect of the three-dimensional mite catcher 100 of the present invention shown in FIG. 3 and the mite capture effect of the conventional two-dimensional adhesive sheet shown in FIG. 4 are compared, it is clear that the present invention is used. The effect of capturing mites on the three-dimensional mite catcher 100 is large, and its superiority can be understood.

Although the preferred embodiments of the three-dimensional mite catcher of the present invention have been illustrated and described above, it will be understood that various modifications can be made without departing from the technical scope of the present invention.

The three-dimensional mite catcher of the present invention can be provided as a mite catching sheet for catching mites. For example, it can be provided as a mite capture sheet for capturing mites that propagate on futons, blankets, mattresses, rugs, mattresses, tatami mats, rugs, sofas, cushions, automobile seats and the like.
