Description

The present invention relates to a foreign object adsorption and capture device having a laminated adhesive mat for removing dust. More specifically, the present invention relates to a technology that allows a foreign object adsorption and capture device having an adhesive mat for capturing foreign objects such as sand, dust, and dirt brought in from the outside by adhering to the human body, clothing, and shoes, which are avoided in facilities such as gymnasiums and manufacturing plants, to be folded at least in two, making it applicable to a variety of uses, increasing convenience and dramatically increasing the opportunities for use, thereby further increasing safety for users of gymnasiums, for example.

Foot-operated adhesive mats, which have an adhesive surface and can adsorb sand and dust adhering to footwear such as shoe soles by standing on the mat, and can also drop foreign objects such as dust and dirt adhering to clothing and the human body, and capture the foreign objects on the adhesive surface, are widely known and used. Various proposals have also been made for products with improved convenience. For example, Patent Document 1 proposes a dust-removal mat configured by stacking a desired number of sheets, each sheet having an adhesive layer with a specific surface adhesive strength, on paper or nonwoven fabric. This dust-removal mat is configured so that when the adhesive surface of the adhesive layer located on the outermost surface (hereinafter referred to as the adhesive surface) becomes dirty due to dust adsorption, it can be peeled off to expose a new adhesive surface for use. For example, Patent Document 2 proposes a laminated adhesive mat for dust removal with improved antistatic performance, which adds additional functions by making the constituent material of the base film and the adhesive constituting the adhesive film to be laminated on the base film unique.

The adhesive mats as described above are extremely simple in structure, easy to use, and do not require any special equipment or power, and are therefore widely used in facilities such as gymnasiums and manufacturing factories. By using the adhesive mats, it is possible to prevent athletes from slipping or even getting injured during competitions or practice of basketball, volleyball, badminton, futsal, and other sports held in gymnasiums, which may be caused by foreign objects such as sand, dust, and dirt that have adhered to shoes, human bodies, or clothing and entered the gymnasium. In manufacturing factories, the use of the adhesive mats as described above promotes cleanliness in the manufacturing site, and improves the quality of the manufactured products.

In particular, when a laminated adhesive mat, which is made by stacking a desired number of sheets each having an adhesive layer as described above, becomes dirty after adsorbing and capturing foreign matter, a new adhesive surface can be exposed by simply peeling off one of the dirty sheets, making it possible to capture foreign matter with an adhesive surface that is always in good condition. Therefore, the laminated adhesive mat can be used continuously for a long period of time, and in some cases, can be used as if it were an immovable installation, by exposing a new adhesive surface according to the degree of surface dirt or for a set period of time.

Japanese Unexamined Patent Publication No. 122536/1983 Patent No. 2939431

The inventor has studied the above-mentioned various sticky mats and found that the following situation requires improvement. Sticky mats are placed in a fixed state at the entrance of facilities such as manufacturing plants where foreign objects are undesirable, and effectively prevent foreign objects from being brought in. However, in facilities such as gymnasiums that are widely used for various purposes, sticky mats are often not installed. In gymnasiums where sticky mats are not installed, foreign objects such as sand, dust, and dirt are easily brought in from the outside by adhering to shoes, human bodies, and clothing, and as a result, users playing sports or practicing are more likely to slip on foreign objects or even get injured, and it has been found that installing sticky mats is effective. In addition, the inventor has observed that when sticky mats are placed on the floor of the entrance of a facility such as a gymnasium and visitors take the action of removing dust by stepping on the sticky mat thoroughly, the amount of foreign objects brought into the gymnasium can be significantly reduced. The inventors further confirmed that by using a laminated adhesive mat and exposing a new adhesive surface depending on the degree of dirt on the topmost adhesive surface, it is possible to more reliably reduce the introduction of foreign matter into the gymnasium.

Furthermore, according to the inventor's investigations, whether it is a non-laminated adhesive mat or a laminated adhesive mat for dust removal consisting of a desired number of laminated adhesive sheets with adhesive layers (hereinafter referred to as a laminated adhesive mat), these adhesive mats are usually prepared and fixed to the floor surface by the provider of the facility such as a gymnasium, and it is rare for the users of the gymnasium, who are the individuals who actually play or practice there, to prepare and install the adhesive mats. The above current situation shows that it is the users of the facility who are injured by foreign objects brought into the gymnasium, but at the same time, even if the users themselves understand that the risk of injury can be reduced by using an adhesive mat, they are in a state where they are unable to take proactive action to protect themselves, posing a serious safety issue.

The inventor also recognized that another problem was that conventional sticky mats leave a weak impression when installed, and that even when installed, they have almost no presence, and that because of this, even if a sticky mat is installed, foreign matter such as sand, dust, and dirt that adheres to shoes, human bodies, and clothing and is brought in from the outside cannot be sufficiently attracted to or dropped onto the sticky surface of the sticky mat to be captured. In other words, even if a conventional sticky mat is installed at the entrance to a facility such as a gymnasium, the current situation is that the excellent functions that the sticky mat originally possesses are not fully exhibited because it does not give a strong impression to visitors that the sticky mat is "for the purpose of removing foreign matter such as sand, dust, and dirt that adheres to human bodies, clothing, and shoes and is brought in from the outside."

Therefore, the main object of the present invention is to provide a laminated adhesive mat that enables users of facilities such as gymnasiums to prepare and install their own adhesive mats. Specifically, based on the common knowledge that it is the provider of facilities such as gymnasiums who installs adhesive mats, the present invention aims to develop and provide a new laminated adhesive mat product that is small, easy to carry by users of facilities such as gymnasiums, and does not reduce the functions of conventional adhesive mats, preferably, has improved functions. Furthermore, the present invention aims to develop and provide a new laminated adhesive mat product that can be suitably applied to new applications such as removing dust and dirt attached to fingertips and clothes due to static electricity by adsorbing them to the adhesive surface of the laminated adhesive mat without washing them off with water, and that gives a natural and smart impression when placed on a desk or wall, without reducing the functions of conventional adhesive mats. Another object of the present invention is to provide a more preferable laminated adhesive mat product, particularly for a foot-operated laminated adhesive mat, that has been improved to a configuration that can fully achieve its original purpose of "removing foreign matter such as sand, dirt, and dust that adheres to shoes, the human body, and clothing and is brought in from the outside." Specifically, the object is to provide a more preferable laminated adhesive mat product that has been improved to a configuration that fully demonstrates the functions of the adhesive mat by implementing measures that encourage visitors to actively step on the foot-operated laminated adhesive mat thoroughly.

The above object can be achieved by the present invention, which provides the following foreign matter absorbing and capturing device.

As a result, groups and individuals using a facility such as a gymnasium can bring in their own foreign object suction and capture device as needed and set it up in a more effective position for use. As a result, in cases where a facility such as a gymnasium does not have an adhesive mat for capturing and removing foreign objects, or where the installation position does not match the user's desire, the user can proactively think about ensuring safety when playing or practicing, which is an extremely useful effect related to safety. Furthermore, according to the present invention, by making the form of the foreign object suction and capture device having a laminated adhesive mat into a structure that can be folded into two or more, in addition to the above-mentioned effects, the following effects can be obtained.

The present invention will be described below with reference to preferred embodiments. Conventionally, it has been common knowledge that the provider of a facility such as a gymnasium installs sticky mats, but in reality, it is the individual users of the facility such as a gymnasium who are injured when foreign objects such as sand, dirt, and dust are brought into the facility from outside. The inventors recognized that there is an urgent need to improve the current situation in which those who are aware of the importance of preventing foreign objects from being brought into the facility are unable to take safety measures to protect themselves.

In response to this, and based on the above-mentioned understanding, the present inventors have conducted extensive research into a method for easily bringing into gymnasiums and other facilities a laminated adhesive mat for removing dust, which has traditionally been used to remove foreign matter such as sand, dirt, and dust by sequentially peeling off multiple laminated adhesive sheets to expose new adhesive surfaces, and have arrived at the present invention.

First, the laminated adhesive mat constituting the foreign matter adsorption and capture device of the present invention has a foreign matter capture part at least partially transparent or opaque, and the foreign matter capture part is similar to conventional products in that the foreign matter capture part is formed by laminating multiple adhesive sheets, each of which is composed of a substrate having a thickness of 10 μm to 200 μm and one side of which has releasability, and an adhesive layer having a thickness of 1 μm to 200 μm formed on the non-releasable side of the substrate, with the releasable side of the substrate in contact with the adhesive layer. The foreign matter adsorption and capture device of the present invention is characterized in that the foreign matter capture part constituting the laminated adhesive mat has two or more fractional parts each having a structure formed by laminating multiple adhesive sheets as described above. Furthermore, the foreign matter adsorption and capture device of the present invention is characterized in that the fractional parts of the foreign matter capture part each have a structure in which they are integrated, either in a peelable or non-peeling state, with a support structured to be foldable at least in two.

The foreign body adsorption/capturing device of the present invention can also be configured such that at least one of the fractional portions of the foreign body capture section is transparent. In this case, the substrate constituting the adhesive sheet is made transparent, and the fractional portion of the foreign body capture section formed by laminating the adhesive sheet is made transparent. In this case, it is effective to further provide a substrate portion to hold and integrate the fractional portion of the transparent foreign body capture section, and to make the substrate portion non-transparent and provided with a colored portion having an image. In this way, the non-transparent substrate portion can be visually recognized from the transparent foreign body capture section. The remarkable effect obtained when the foreign body adsorption/capturing device of this embodiment is configured such that one of the fractional portions of the foreign body capture section has a transparent laminated adhesive mat will be described later.

Details of the foreign object adsorption and capture device of the present invention will be described below with reference to the drawings showing representative examples. The foreign object adsorption and capture device of the present invention has a structure that can be folded in two, for example, as shown in FIG. 3. To achieve such a structure, for example, a support (hereinafter simply referred to as a support) having a structure that can be folded in two or more is formed from sheet-like members in the same number or more than the fractional parts of the foreign object capture part of the laminated adhesive mat, and these multiple members are integrated with two or more fractional parts of the foreign object capture part constituting the laminated adhesive mat in a peelable or non-peeling state, and the integrated members are connected to each other by a foldable connecting material. In the example shown in FIG. 1 and FIG. 2, the support is composed of two sheet-like members 1 and 2, and two fractional parts of the foreign object capture part constituting the laminated adhesive mat are integrated with each of the members, and these are connected by a flexible connecting material to form a structure that can be folded in two. Each of the above-mentioned configurations will be described in detail below.

[Laminated adhesive mat]
The laminated adhesive mat constituting the present invention is essentially composed of a plurality of laminated adhesive sheets and has a foreign body capture section, at least a portion of which is transparent or opaque, and may further have a base material for holding and integrating the foreign body capture section as required, and has a structure in which at least the foreign body capture section is divided into a plurality of sections. Each of the components will be described below.

(Foreign object capture section: adhesive sheet laminate)
The foreign body capture section is formed by laminating a plurality of adhesive sheets, each of which is composed of a transparent or opaque substrate having a thickness of 10 μm to 200 μm and one surface of which has releasability, and an adhesive layer having a thickness of 1 μm to 200 μm formed on the non-releasable surface of the substrate, in a state in which the adhesive layer is in contact with the releasable surface of the substrate. In a preferred embodiment of the present invention, the substrate and the adhesive layer are made transparent. By making the substrate and the adhesive layer transparent, the foreign body capture section formed by laminating a plurality of transparent adhesive sheets becomes transparent. Since the foreign body capture section constituting the present invention has a plurality of fractional parts, it is possible to make a configuration in which some or all of the fractional parts of the foreign body capture section are made transparent. If a transparent foreign body capture section, which is a laminate of transparent adhesive sheets, is held by a substrate and integrated in a peelable or non-peeling state, and the substrate is configured to have a non-transparent colored part having an image, the image can be visually recognized from the transparent foreign body capture section side. Of course, as in the conventional case, the base material constituting the adhesive sheet may be formed from a non-transparent material, and the foreign matter capturing portion of the laminated adhesive mat constituting the present invention may have no transparent portion.

<Transparent or opaque substrate constituting the pressure-sensitive adhesive sheet>
The substrate constituting the laminated adhesive sheet of the foreign body capture section is a transparent or opaque plastic film having a thickness of about 10 μm to 200 μm, preferably about 30 μm to 60 μm, one side of which has releasability. The transparency of the plastic film in this case may be such that, when, for example, about 30 to 60 sheets of adhesive sheets are laminated to form the foreign body capture section, the image on the substrate can be seen from the foreign body capture section side. In addition, since the user is to stand on it and encourage stepping on it, a substrate having excellent strength is used. Specifically, for example, polyvinyl chloride, polyester, polypropylene non-oriented film (CPP), polypropylene oriented film (OPP), polyethylene, polyamide (nylon: registered trademark), synthetic paper, etc. can be used. Among these, polyester, polyethylene, etc. are preferably used in consideration of strength and environmental load when discarded. The adhesive sheets constituting the laminated adhesive mat used in the present invention form the foreign body capture section in a state where multiple sheets are laminated, and are peeled off one by one when used, so a substrate having one side of which has releasability is used.

<Adhesive layer that makes up the adhesive sheet>

In the present invention, an adhesive layer having a thickness of 1 μm to 200 μm is formed on the non-releasable surface of the above-mentioned substrate to form an adhesive sheet. Any adhesive used in the manufacture of conventionally known adhesive sheets can be used to form the adhesive layer. For example, any conventionally known adhesive such as acrylic, rubber, hot melt, emulsion, urethane, and silicone can be used. The thickness of the adhesive layer may be about 1 μm to 200 μm, preferably about 2 μm to 60 μm, and more preferably 2 to 30 μm. This is no different from conventionally known adhesive sheets. In the present invention, when one of the fractional parts of the foreign matter capture section is made transparent, in addition to using a transparent material for the substrate described above, an adhesive that makes the adhesive layer formed on the substrate have excellent transparency is selected and used.

<Number of layers of adhesive sheets in foreign object capture section>
The laminated adhesive mat constituting the present invention has a foreign object capture part at least partially transparent or opaque, which is formed by laminating a plurality of transparent or opaque adhesive sheets made of the above-mentioned materials in a state in which the releasable surface of the base material of the adhesive sheet is in contact with the adhesive layer of another adhesive sheet. The number of adhesive sheets to be laminated is not particularly limited. For example, in consideration of convenience, assuming that the user goes to a gymnasium or the like for practice every day, about 30 adhesive sheets may be laminated so that the adhesive sheet that is used and soiled can be peeled off and replaced with a new adhesive surface every day. In addition, for example, assuming that it is suitable for individual competitions held in a gymnasium or the like, several to about 10 of the above-mentioned adhesive sheets may be laminated. In addition, in order to ensure that the adhesive sheets of the laminated foreign object capture part are peeled off one by one in order and used, it is also a preferred embodiment to number a part of each adhesive sheet so that the number of sheets stacked can be instantly known. Furthermore, it is also preferable to provide an area at the edge of the adhesive sheet where no adhesive layer is formed and to number the area so that the laminated adhesive sheets can be easily peeled away from each other to expose the next adhesive sheet at the same time as the numbering. As will be described later, the laminated adhesive mat constituting the present invention has a foreign matter capturing portion having two or more partitioned parts, and since the degree of dirt may not be uniform, it is preferable to apply the above-mentioned measures to each partitioned part.

<Morphology when any of the fractional parts of the foreign body capture part is transparent>
In the case where any of the divided parts of the foreign object trapping part of the laminated adhesive mat constituting the foreign object adsorption and trapping device of the present invention is made transparent, it is preferable to have a structure in which the divided part of the transparent foreign object trapping part is integrated with the base part on which the colored part having an image is provided in a peelable or non-peeling state, as shown in (2) of FIG. 4. With this configuration, the image of the colored part provided on the integrated base part can be seen from the transparent divided part side of the foreign object trapping part, so that a visual effect by the image can be given. In this case, it is preferable to use a non-transparent sheet-like or plate-like member as the base part used. For example, a sheet-like or plate-like material made of plastic, wood, rubber, etc. can be used as the material for forming the base part. Examples of plastic include general-purpose materials such as polyvinyl chloride and polypropylene. The sheet-like or plate-like member made of these materials may be provided with a means for fixing the foreign object trapping part having the above-mentioned configuration, firmly holding it, and integrating it. For example, a method of bonding using a transparent adhesive can be used as a means for fixing the foreign object trapping part having a transparent divided part to the base part, firmly holding it, and integrating it.

In the foreign object adsorption and capture device of the present invention, at least one of the fractional parts of the foreign object capture part constituting the laminated adhesive mat is made transparent, and a colored part having an image is provided on the base part integrated with the transparent foreign object capture part, so that when the product is used, the image formed on the base part can be viewed from the transparent part of the foreign object capture part, as shown in Figure 3. In this case, the colored part having an image can be formed, for example, by printing on a non-transparent sheet-like base part, or by bonding the base part and the transparent fractional part of the foreign object capture part with an adhesive while a printed matter is placed on the sheet-like base part to integrate them.

If the image on the colored part is a message or pattern that naturally encourages visitors to the gymnasium or other facility other than the person who installed it to cooperate actively in removing foreign matter such as sand, dirt, and dust that is brought in from the outside and adheres to shoes, human bodies, and clothing, then as a secondary effect, it can increase the awareness of those who experience the above not to bring foreign matter into the gymnasium or other facility. As a result, even before stepping on the laminated adhesive mat, people will make an effort not to bring trash or foreign matter into the site.

Examples of the above-mentioned effective messages include text displays such as those shown below. It is also preferable to display footprints as shown in Figure 3, pictures that make people aware of their feet, or pictures that call attention, together with these messages, or independently. Pictures can be understood by people all over the world, and in today's internationalized world, they can instantly help people understand the purpose of installing the laminated adhesive mat more quickly than a text message, so they are a good choice.

- "Step here!"
- "Step! 1, 2, 3, 4, 5"
・"No trash allowed"
- "STOP! Start stomping!"
・"STOP! DO YOUR BEST"

The foreign object suction and capture device of the present invention is characterized by being easily carried into facilities such as gymnasiums by individuals or groups who use the facility, and therefore in the preferred embodiment described above, the messages and designs visible from the transparent foreign object capture section can be diverse, reflecting the values and hobbies of the person or group who carries it in. When configured in this way, the product can provide a variety of visual effects more suited to the user. In order to more easily obtain such products, it is preferable to have a configuration in which a printed material is placed on the base material. By using images of the printed material, it becomes easier to provide products that appropriately meet a variety of needs.

[Support structure that can be folded at least in two]
The foreign matter absorbing and capturing device of the present invention is characterized in that the laminated adhesive mat having the foreign matter capturing portion having a structure with at least two divided parts as described above is integrated in a peelable or non-peeling state with a support structured to be foldable in at least two. This support will be described below.

(Materials of Support)
What is important in the present invention is that the support constituting the present invention has a structure that can be folded at least in two while supporting the laminated adhesive mat, is as light as possible to facilitate carrying, and is required to be able to firmly support the laminated adhesive mat, and furthermore, to have sufficient strength and excellent durability even when the user steps on the laminated adhesive mat. The foreign matter adsorption and capture device of the present invention can be structured such that the laminated adhesive mat is integrated with the support in a peelable state. In this case, the laminated adhesive mat, which is used by sequentially peeling off the adhesive sheets whose adhesive surface is dirty, becomes a consumable item that is replaced when the laminated adhesive sheets are used up. However, since the support can be used repeatedly, particularly in this case, the support is required to have durability sufficient to withstand repeated use. The support constituting the present invention needs to be manufactured taking into consideration the above-mentioned usage circumstances.

Materials for the support constituting the present invention include, for example, plates of about 1 to 30 mm, preferably about 2 to 20 mm, made of plastics such as polyvinyl chloride (PVC), polypropylene, polyester, polyethylene, polystyrene, polycarbonate, ABS, EVA (ethylene-vinyl acetate copolymer resin), paper, wood, and rubber. Among these, polyvinyl chloride and polypropylene are preferred. It is also preferred to manufacture the support using a composite material in order to make the support thin and strong. It is also preferred to use a foamed or porous material to reduce the weight. For example, it is also preferred to use reinforced cardboard, plastic cardboard, and honeycomb-structured sheets.

(Folding structure of support tool)
There is no particular restriction on the method of folding the support made of the above-mentioned material at least in two while supporting the laminated adhesive mat having the foreign object capture portion. The number of folds is also not particularly limited, although it depends on the size of the foreign object adsorption capture device of the present invention. As shown in the example, it is common to fold it in two, but it may be folded in three or four, for example. The more the number of folds, the more compact it can be. However, if the number of folds is increased, in addition to the structure becoming complicated, there is a concern that another problem will arise, such as the inability to sufficiently secure a wide, uniform adhesive surface without interruption, so in the case of a foot-operated foreign object adsorption capture device, it is preferable to fold it in two or three.

As shown in Figures 1, 2 and 5, for example, the support is composed of sheet-like or plate-like members 1 and 2, which respectively support the divided parts of the foreign body capture section, and these two members are connected using a connecting material made of a different material. The connecting material is, for example, a material that is flexible and has sufficient durability when repeatedly folded and used. Examples of such materials include plastics such as polypropylene and polyvinyl chloride, various rubber materials, fabrics, nonwoven fabrics, artificial leather, and leather.

The sheet-like or plate-like members for supporting the multiple fractional parts of the foreign body capture section and the connecting material required for folding may be integrally formed as one member, as shown in FIG. 6. In this case, the sheet-like or plate-like members and the connecting material may be the same material or different materials. It is also preferable to use a so-called hinge as the connecting member.

The foreign body adsorption/capturing device of the present invention may have a structure in which a plurality of adhesive sheets are laminated as a laminated adhesive mat to be integrated with a support, and may have a structure having a foreign body capture section having a plurality of fractional parts and a base part that is integrated while holding the foreign body capture section. It is also useful to use a long base part as the laminated adhesive mat before being integrated with the support, and place a plurality of fractional parts constituting the foreign body capture section on this base part, and in that state, have a structure that can be folded in two or more. For example, the example shown in FIG. 7 uses a support having sheet-like members 1 and 2 that respectively support the fractional parts of the foreign body capture section, and these members are made to hold the fractional parts of the foreign body capture section of the laminated adhesive mat having the above-mentioned long base part, and are firmly integrated. In such a configuration, depending on the material of the base part constituting the laminated adhesive mat, it is also possible to use the base part constituting the laminated adhesive mat as a connecting material constituting the support described above, as shown in FIG. 7. In other words, in this case, it is possible to design the support so that it does not require special connecting materials to create a structure that can be folded in two or more parts.

The example of FIG. 8 is a structure in which a long foreign object capture part is used and a punching process is performed in the center of the short width direction so that it can be folded in two. In this case, as in the example of FIG. 7, a long base part is used, a foreign object capture part of approximately the same shape as the long base part is arranged on it and integrated, and then a punching process is performed in the center of the short width direction of the member formed by integrating the base part and the foreign object capture part, so that it can be folded in two. In the example shown in FIG. 8, two left and right divided parts are formed through the punching process. In the example of FIG. 9, the punching process performed in the center of the member formed by integrating the base part and the foreign object capture part is provided along the longitudinal direction of the member, and the structure is such that it can be folded through the punching process part, and the divided parts are formed above and below the foreign object capture part through the punching process part. The die-cut portion is shown enlarged and schematic in Figures 8 and 9, but in either case, it is sufficient to be able to fold through this portion, and it may be so-called perforation processing or crease processing, for example.

For example, in the example of FIG. 9, the molded portion forms separate portions above and below the foreign body capture portion, so if the adhesive layer in this state is stepped on, there is a concern that the separate upper and lower portions will stick to the sole of the shoe and lift up if the adhesive layer is not firmly fixed to the floor. This problem can be solved by the following simple method. For example, as shown in FIG. 9, a preferred embodiment uses rod-shaped protrusions as a means for preventing the adhesive surfaces of the adhesive layer from sticking to each other when folded, as explained above, and the rod-shaped protrusions are made to fit in place, so that the separate portions can be fixed to the upper and lower positions by moving the position of the rod-shaped protrusions when in use.

(Means for preventing the adhesive surface of the adhesive layer from sticking when folded)
The foreign matter adsorption/capturing device of the present invention has a structure that can be folded in two or more, but the folding direction may be such that the support is on the outside and the laminated adhesive mat is on the inside, or the support is on the inside and the laminated adhesive mat is on the outside. When folded so that the laminated adhesive mat is on the inside, the adhesive surfaces of the outermost surfaces of the divided parts of the foreign matter capture part that constitute the laminated adhesive mat face each other (face each other). Therefore, in this case, it is necessary to provide an anti-sticking member or the like that has a structure that can reliably prevent the adhesive surfaces from sticking to each other. As a means for this, for example, as shown in FIG. 1, a method can be given in which, in a state where the laminated adhesive mat is integrated with the support, a frame-like structure that is slightly higher than the height to the exposed adhesive surface, which is the outermost surface of the laminated adhesive mat, is provided on the support as an anti-sticking member at a position around the laminated adhesive mat placed on the support. In this case, in the example shown, a frame-like structure is provided on both member 1 and member 2 of the support, but this is not limited to this, and if the height of the frame is made sufficiently high, a frame-like structure may be provided on only one of the members (not shown).

In the above configuration, the frame provided on the support as the sticking prevention member does not necessarily have to be frame-shaped. For example, a method of providing a long member that is taller than the height of the adhesive surface that is the outermost surface of the divided portion of the foreign object capture portion along at least one opposing side of the divided portion of the foreign object capture portion of the laminated adhesive mat, for example, a configuration in which one of the frames constituting the frame illustrated in Figure 1 is provided (not shown), may be used. In this case, too, the sticking prevention member may be provided on both member 1 and member 2 of the support as shown in Figure 1, or may be provided on either member 1 or member 2 of the support as explained above.

As shown in Figures 2 and 3, it is also effective to provide multiple convex members (protrusions) higher than the height of the adhesive surface that is the outermost surface of the divided part of the foreign object capture section on both members 1 and 2 of the support as anti-sticking members, in positions that face each other when folded. In this way, when the foreign object suction and capture device of the present invention is folded so that the adhesive surfaces face each other (face to face), the protrusions come into contact with each other earlier than the adhesive surfaces come into contact with each other, thereby preventing the adhesive surfaces from sticking to each other. In this case, as in the case described above, the protrusions that function as anti-sticking members may be provided on either member 1 or member 2 of the support.

In either of the above cases, by providing the anti-sticking member, when the foreign matter adsorption and capture device of the present invention is folded and the adhesive surfaces are placed facing each other, the anti-sticking members come into contact with each other earlier than the adhesive surfaces come into contact with each other, or the anti-sticking member comes into contact with the opposing surface of the support, so that it is possible to effectively prevent the adhesive surfaces from sticking to each other. Note that the shape of the anti-sticking member used in the present invention and the positions and number of the anti-sticking members are not particularly limited as long as they can prevent the adhesive layers from sticking to each other when the foreign matter adsorption and capture device of the present invention is folded and the adhesive surfaces are placed facing each other.

As a method for preventing the adhesive surfaces of the adhesive layer from sticking to each other, it is of course effective to place a paper or plastic sheet with a release surface (hereinafter, these may be collectively referred to as "release sheet") between the opposing adhesive surfaces. In this case, it is necessary to remove the release sheet during use when the foreign matter adsorption and capture device of the present invention is not folded. For this reason, in the case of a release sheet that is installed in an independent state, there is a problem that it is necessary to store the release sheet during use. In addition, while the foreign matter adsorption and capture device of the present invention is folded and transported, the release sheet may come off from between the opposing adhesive surfaces, making it impossible to prevent the adhesive surfaces from sticking to each other.

Methods for solving the above problems include, for example, integrating a release sheet into the foreign object adsorption/capturing device as described below. For example, as shown in Figures 10 and 11, the support may be a three-fold type consisting of three divided parts, with two adjacent divided parts holding a laminated adhesive mat, and the front and back surfaces of the remaining divided part being formed from a material that has releasability or a material that has been treated for release, giving it the function of a release sheet. In this way, as shown in Figure 11, it is integrated into the foreign object adsorption/capturing device without coming off even during use, so that the divided part that has been given the function of a release sheet is not lost during use or transportation.

The foreign object adsorption and capture device of the present invention can also be folded, as shown in FIG. 8, so that the support is on the inside and the divided part of the foreign object capture part of the laminated adhesive mat is on the outside. In this case, the adhesive surfaces of the outermost surfaces of the divided parts do not face each other and stick to each other, but the adhesive surfaces of the outermost surfaces of the divided parts of the foreign object capture part are exposed to the outside, so they stick to various things. In order to avoid sticking that occurs in this case, it is preferable to prepare a dedicated storage device and store the foreign object adsorption and capture device of the present invention in a folded state in the storage device. The storage device may be a box-shaped, bag-shaped, or furoshiki-shaped one. What is important is that when the foreign object adsorption and capture device of the present invention is folded and stored in the storage device with the adhesive surface of the outermost surface of the foreign object capture part exposed to the outside, the part of the storage device that may come into contact with the adhesive surface has releasability. Specifically, one method would be to make the inside surface of the storage box or bag releasable, or to make at least one surface of a wrapping cloth-like object releasable.

Specifically, it is preferable to form the inner surface of the storage box with release paper. As the release paper, paper such as fine paper, flat paper, craft paper, glassine paper, synthetic paper, etc. with at least one side treated for release, or plastic film, etc. can be used. Furthermore, if the storage device is in the form of a bag or furoshiki, in addition to the materials listed above, for example, uneven fabric with a reduced contact area, plastic material such as nylon, or cloth or nonwoven fabric with at least one side treated for release can be used.

The size and shape of the foreign object adsorption/capturing device of the present invention may be appropriately determined depending on the purpose of use and the location where it is installed, and are not particularly limited. The important points of the present invention are that the size (area) of the laminated adhesive mat is appropriate for the purpose, and that it is easy to carry when folded. For example, when unfolded, the shape of the laminated adhesive mat may be a polygon such as a rectangle, square, or trapezoid, or a circle, ellipse, or cloud shape, with short sides of about 10 cm to 90 cm and long sides of about 10 cm to 200 cm. It may be designed appropriately taking into account folding. For this reason, the shapes of the multiple fractional parts of the foreign object capture part that constitute the laminated adhesive mat do not necessarily need to be the same, and may be designed appropriately taking into account folding and the purpose of use.

The foreign object suction and capture device of the present invention is used by individuals or groups who use facilities where they do not want to bring in trash or foreign objects by setting it up in a folded state near the entrance of the facility. Examples of facilities include gymnasiums, various classrooms, rental meeting rooms, rental classrooms, rental halls, rental galleries, and rental spaces. In recent years, the number of people who enjoy hobbies has increased, and hobbies have also become more diverse. In various situations, importance is being placed on measures to prevent foreign objects from getting into products when making things, consideration for exhibits, and preventing injuries during competitions and practice. The foreign object suction and capture device of the present invention, which is easily portable, can meet the diverse needs of various people.

In recent years, hay fever has become a problem, and people are reluctant to bring these foreign objects into their homes and workplaces, and the foreign object adsorption and capture device of the present invention can effectively meet such demands. For example, when used seasonally, it has the advantage of being able to be folded up and stored compactly when not in use. Depending on the desired location for installation, the configuration of the foreign object adsorption and capture device of the present invention needs to be improved in design, but the laminated adhesive mat constituting the foreign object adsorption and capture device of the present invention can be made into a foreign object capture part with at least a part being transparent, and by integrating the transparent foreign object capture part with a base part having a colored part with an image while holding it, the image can be viewed from the transparent foreign object capture part side, making it easy to provide a product with excellent design. Specifically, a non-transparent sheet-like member is used as the base part, and printing is performed directly or by transfer onto this sheet-like member, or a printed material can be placed between the non-transparent base part having a colored part with an image and the foreign object capture part when they are integrated.

The printed matter used in this case may be, for example, printed on fine paper, synthetic paper, photographic paper, polylaminated paper, tarpaulin, cloth, plastic film, etc. The impression of the laminated adhesive mat used in the present invention can be changed depending on the material used. The plastic film may be, for example, polyvinyl chloride, polyester, unstretched polypropylene film (CPP), oriented polypropylene film (OPP), polyethylene, polyamide (nylon: registered trademark), etc. If the printed matter is formed using an inkjet recording method, the content of the printed matter can be easily and freely made diverse, thereby improving the visual effect.

The foreign matter adsorption and capture device of the present invention can be used as a foot-operated laminated adhesive mat, which was explained as a representative example, but it can also be used for the purpose of adsorbing and removing foreign matter such as dirt and dust on fingertips and gloves, which can be problematic during various tasks. When used as a foot-operated laminated adhesive mat, it is preferable to fix it firmly to the floor at the entrance of a facility such as a gymnasium so that it can be placed there. When used to adsorb and remove foreign matter on fingertips, it is preferable to fix it to a desk or wall so that it can be placed there. Methods for fixing it to a floor or wall include providing a fixing part made of a non-slip material described later or an adhesive part made of a peelable adhesive that can be firmly fixed to the surface of the support device constituting the present invention on the surface on which the laminated adhesive mat is not placed.

The adhesive portion for fixing the foreign object adsorption and capture device of the present invention to a floor or wall surface must be able to be firmly fixed to the floor surface, particularly when used as a step-on laminated adhesive mat, as the product encourages people to stand on and step on it. To achieve this, it is preferable to form the adhesive portion for fixing to the floor surface using an adhesive with an adhesive strength of 1 N/cm or more. Specifically, for example, an adhesive such as an acrylic, rubber, hot melt, emulsion, urethane, or silicone adhesive can be used to form an adhesive portion with the above-mentioned strength. It is also preferable to select and use an adhesive that leaves no adhesive residue when the foreign object adsorption and capture device of the present invention is peeled off from the floor surface.

The foreign object adsorption and capture device of the present invention is often used by being placed and fixed at an appropriate position on the floor surface, or by being fixed at a specific position on the wall surface. One of the methods for fixing the foreign object adsorption and capture device of the present invention is a method using an adhesive. In particular, there are cases where the device is fixed to the floor surface and used by stepping on it, or where the device is fixed to a position where falling objects are not allowed depending on the wall surface of the work area. In such cases, in consideration of safety during use, it is preferable to fix the device to the floor surface or wall surface using an adhesive with a strong adhesive strength of 1 N/cm or more. On the other hand, considering the need to peel it off and take it home after use, it is preferable to select and use an adhesive that leaves little glue residue. In addition, as a method of fixing the device other than the method using an adhesive, there are cases where a suction cup that enables fixing to a smooth surface is used, and a member made of an anti-slip material such as an adhesive resin such as urethane, silicone, or acrylic, a natural rubber-based, diene rubber such as CR or SBR, a non-diene rubber such as butyl rubber, or EPDM, or various sponges such as urethane sponge is arranged between the floor surface and the foreign object adsorption and capture device.
