Description

[Technical field]

[0001] The present invention relates to a foreign object suction and capture device having a laminated adhesive mat for removing dust. More specifically, the present invention relates to a technology that makes it possible to fold a foreign object suction 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, clothes, and shoes, which are avoided in facilities such as gymnasiums and manufacturing factories, at least in two parts, thereby making it possible to apply the device to various uses, increasing convenience and dramatically increasing the number of opportunities for use, and as a result, further increasing safety for users of gymnasiums, for example. [Background technology]

[0002] Conventionally, foot-operated adhesive mats that adsorb sand and dust adhering to footwear such as shoe soles by stepping on the mat with an adhesive surface, and that allow foreign objects such as dust and dirt adhering to clothing and the human body to fall off 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 on paper or nonwoven fabric, each sheet having an adhesive layer with a specific surface adhesive strength. This dust-removal mat is configured so that when the adhesive surface (hereinafter referred to as the adhesive surface) of the adhesive layer located at the outermost surface becomes dirty due to dust adsorption, it can be peeled off to expose a new adhesive surface for use. Also, for example, Patent Document 2 proposes a dust-removal laminated adhesive mat with improved antistatic performance, which is further enhanced by adding 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.

[0003] The adhesive mat having the above-mentioned structure is extremely simple in structure, easy to use, and does not require any special device or power, and is therefore widely used in facilities such as gymnasiums and manufacturing factories. By using the above-mentioned adhesive mat, it is possible to prevent athletes from slipping or even getting injured during competitions or practices such as basketball, volleyball, badminton, and futsal held in gymnasiums, which are caused by foreign objects such as sand, dust, and dirt that have adhered to shoes, human bodies, and clothing and entered the gymnasium. In manufacturing factories, the use of the above-mentioned adhesive mat promotes the cleanliness of the manufacturing site and improves the quality of the manufactured products.

[0004] In particular, when the adhesive surface of a laminated adhesive mat 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 a simple operation of simply peeling off one of the dirty sheets, so that the adhesive surface can always be in good condition to capture foreign matter. 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 performing an operation to expose a new adhesive surface according to the degree of surface dirt or for a set period of time. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 122536 / 1983 [Patent Document 2] Patent No. 2939431 Summary of the Invention [Problem to be solved by the invention]

[0006] The inventor has studied the above-mentioned various sticky mats and found that the following situation is necessary to improve. 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 clothes, and as a result, users playing sports or practicing are more likely to slip on the foreign objects and, in some cases, get injured, and it was found that installing sticky mats is effective. In addition, the inventor has observed that when sticky mats are placed on the floor surface at the entrance of a facility such as a gymnasium and visitors are sure to take the action of removing dust by stepping on the sticky mats, the amount of foreign objects brought into the gymnasium can be significantly reduced. The inventor 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 bringing of foreign matter into the gymnasium.

[0007] Furthermore, according to the inventor's study, whether it is a non-laminated adhesive mat or a laminated adhesive mat for dust removal in which a desired number of adhesive sheets with adhesive layers are laminated together (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, to prepare and install the adhesive mat. 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, which is a serious safety issue.

[0008] Another problem that the inventors of the present invention have is that conventional sticky mats leave a weak impression when installed, and it is no exaggeration to say that even if a sticky mat is installed, it has almost no presence, and 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 clothes 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 of a facility such as a gymnasium, the current situation is that the excellent functions that the sticky mat originally has cannot be fully demonstrated 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, clothes, and shoes and is brought in from the outside."

[0009] Therefore, the main object of the present invention is to provide a laminated adhesive mat that enables each user of a facility such as a gymnasium to prepare and install the adhesive mat by himself / herself. Specifically, based on the common knowledge that the provider of the facility such as a gymnasium installs the adhesive mat, the present invention is to newly develop and provide a laminated adhesive mat product that is small, easy to carry by each user of the facility such as a gymnasium, and does not reduce the functions of the conventional adhesive mat, preferably, has an improved function. Furthermore, the present invention is to newly develop and provide a laminated adhesive mat product that can be suitably applied to a new application such as removing dust and dirt attached to fingertips or 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 does not reduce the functions of the conventional adhesive mat, but rather improves them, and that gives a natural and smart impression when placed on a desk or wall, for example. Another object of the present invention is to provide a more preferable laminated adhesive mat product, especially for a stepping-type laminated adhesive mat, 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 improved to a configuration that fully exhibits the functions of the adhesive mat by implementing a device that actively encourages visitors to step on the stepping-type laminated adhesive mat thoroughly. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The present invention will be described below with reference to preferred embodiments. The present inventor recognized that, while it is common knowledge that the provider of a facility such as a gymnasium installs conventional sticky mats, in reality it is the users of the facility who are injured when foreign objects such as sand, dirt, and dust are brought into the facility from outside, and that it is necessary to immediately 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.

[0021] In response to this, and based on the above-mentioned understanding, the present inventors have conducted extensive research into a method for making it possible to easily bring into facilities such as gymnasiums 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 a new adhesive surface, and have arrived at the present invention.

[0022] 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 a conventional product in that the foreign matter capture part is formed by laminating a plurality of adhesive sheets each consisting of a substrate having a thickness of 10 μm to 200 μm and having releasability on one side, and an adhesive layer having a thickness of 1 μm to 200 μm formed on the non-releasable side of the substrate, in a state in which the releasable side of the substrate and the adhesive layer are in contact with each other. 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 a plurality of 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 with a support structured to be folded at least in two, in a peelable or non-peeling state.

[0023] In addition, the foreign matter adsorption and capture device of the present invention can be configured such that at least one of the fractional parts of the foreign matter capture part is transparent. In this case, the base material constituting the adhesive sheet is made transparent, and the fractional part of the foreign matter capture part formed by laminating the adhesive sheet is made transparent. In this case, it is effective to further provide a base material part in order to hold and integrate the fractional part of the transparent foreign matter capture part, and to make the base material part not transparent but in a form provided with a colored part having an image. In this way, the non-transparent base material part can be visually recognized from the transparent foreign matter capture part side. The remarkable effect obtained when the foreign matter adsorption and capture device of this embodiment is configured such that one of the fractional parts of the foreign matter capture part has a transparent laminated adhesive mat will be described later.

[0024] The details of the foreign matter adsorption / capturing device of the present invention will be described below with reference to the drawings showing a representative example. The foreign matter adsorption / capturing device of the present invention has a structure that can be folded in two, for example, as shown in FIG. 3. In order to obtain 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 matter capture part of the laminated adhesive mat, and these multiple members and two or more fractional parts of the foreign matter capture part constituting the laminated adhesive mat are integrated 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 the two fractional parts of the foreign matter 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. Below, each of the above-mentioned configurations will be described in detail.

[0025] [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.

[0026] (Foreign object capture part: 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 a releasable surface, 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 the transparent foreign body capture section, which is a laminate of transparent adhesive sheets, is held by the 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.

[0027] <Transparent or opaque substrate constituting the pressure-sensitive adhesive sheet> The substrate constituting the adhesive sheet laminated with the foreign body capture portion 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 the adhesive sheet is laminated, for example, about 30 to 60 sheets, to form the foreign body capture portion, the image on the substrate portion can be visually recognized from the foreign body capture portion side. In addition, since the product is used by encouraging the user to stand on it and step on it, a material with 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 are stacked together to form a foreign body capture section, and are peeled off one by one when used, so a substrate having one side with releasability is used.

[0028] <Adhesive layer constituting the adhesive sheet>

[0029] In the present invention, a pressure-sensitive adhesive layer having a thickness of 1 μm to 200 μm is formed on the non-releasable surface of the substrate to form a pressure-sensitive adhesive sheet. Any pressure-sensitive adhesive used in the manufacture of conventionally known pressure-sensitive adhesive sheets can be used to form the pressure-sensitive adhesive layer. For example, any conventionally known pressure-sensitive adhesive such as acrylic, rubber, hot melt, emulsion, urethane, and silicone can be used. The thickness of the pressure-sensitive 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 not different from conventionally known pressure-sensitive adhesive sheets. In the present invention, when any of the fractionated parts of the foreign body capture part is made transparent, in addition to using a transparent material for the substrate described above, a pressure-sensitive adhesive that makes the pressure-sensitive adhesive layer formed on the substrate excellent in transparency is selected and used.

[0030] <Number of layers of adhesive sheets in the foreign object capture section> The laminated adhesive mat constituting the present invention has a foreign body capture part, at least a part of which is 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 sheets of the above-mentioned adhesive sheets may be laminated. In addition, in order to ensure that the adhesive sheets of the laminated foreign body 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 capture section having two or more partitioned parts, and the degree of dirt may not be uniform, so that it is preferable to apply the above-mentioned measures to each partitioned part.

[0031] <Morphology when any of the fractions of the foreign body capture section 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.

[0032] In the foreign body adsorption / capturing device of the present invention, if at least one of the divided parts of the foreign body capture part constituting the laminated adhesive mat is made transparent, and a colored part having an image is provided on a base part integrated with the transparent foreign body capture part, the image formed on the base part can be viewed from the transparent part of the foreign body capture part when the product is used, as shown in Fig. 3. In this case, examples of methods for forming the colored part having an image include printing on a non-transparent sheet-like base part, or bonding the base part and the transparent divided part of the foreign body capture part with an adhesive to integrate them in a state where a printed matter is placed on the sheet-like base part.

[0033] And if the image on the colored part is a message or a picture that makes visitors to the gymnasium or other facility other than the person who installed it naturally and proactively cooperate in "removing foreign matter such as sand, dirt, and dust that adheres to shoes, human body, and clothing and is brought in from the outside", then as a secondary effect, it can increase the consciousness 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 garbage or foreign matter into the site.

[0034] 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 Fig. 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 globalized world, they can instantly understand the purpose of installing the laminated adhesive mat more than a text message, so they are a good choice.

[0035] "Stand here!" "Step! 1, 2, 3, 4, 5" "No trash allowed" · "STOP! Start stomping!" · "STOP! DO YOUR BEST"

[0036] In addition, since the foreign object suction and capture device of the present invention is characterized by being easily carried into a facility such as a gymnasium by an individual or group using the facility, in the above-mentioned preferred embodiment, the message or picture visible from the transparent foreign object capture part can be made diverse to reflect the values ​​and hobbies of the person or group who carries it in. When configured in this way, the product can obtain various visual effects more suitable for the user. In order to obtain such a product more easily, it is preferable to configure the product so that a printed matter is placed on the base part. By using an image of the printed matter, it becomes easier to provide products that appropriately meet various needs.

[0037] [Support structure that can be folded into at least two parts] The foreign body absorbing and capturing device of the present invention is characterized in that the laminated adhesive mat having the foreign body 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.

[0038] (Support material) 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.

[0039] As the material of the support constituting the present invention, for example, a plate having a thickness of about 1 to 30 mm, preferably about 2 to 20 mm, made of plastic such as polyvinyl chloride (PVC), polypropylene, polyester, polyethylene, polystyrene, polycarbonate, ABS, EVA (ethylene-vinyl acetate copolymer resin), paper, wood, rubber, etc. can be used. Among these, polyvinyl chloride and polypropylene are preferable. It is also preferable to manufacture the support using a composite material for the purpose of making the support thin and having excellent strength. It is also preferable to use a foamed or porous material to reduce the weight. For example, it is also preferable to use reinforced cardboard, plastic cardboard, and a sheet with a honeycomb structure.

[0040] (Folding structure of support) There is no particular limitation 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 section. 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 illustrated, it is common to fold it in two, but it may also be folded in three or four. 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.

[0041] 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 fractional parts of the foreign body capture unit, and these two members are connected using a connecting material made of a different material. For example, the connecting material is 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.

[0042] 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 made of the same material or different materials. It is also preferable to use a so-called hinge as the connecting member.

[0043] The foreign body adsorption / capturing device of the present invention may be a laminated adhesive mat to be integrated with a support, which has a structure in which a plurality of adhesive sheets are laminated, and has a structure in which a foreign body capture section having a plurality of fractional parts and a base part which 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 to place a plurality of fractional parts constituting the foreign body capture section on the base part, and to have a structure in which the laminated adhesive mat can be folded in two or more in this state. For example, the example shown in FIG. 7 uses a support having sheet-like members 1 and 2 which 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 this 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. That is, in this case, it is possible to provide a structure in which it is not necessary to use special connecting materials for the support tool to form a structure that can be folded into two or more parts.

[0044] 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 shown in FIG. 7, a long base part is used, a foreign object capture part having a shape almost the same as that of the long base part is arranged and integrated thereon, 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 divided parts, left and right, 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, and the divided parts are formed at the upper and lower positions of the foreign object capture part through the punching process. The die-cutting portion is shown enlarged and schematic in Figures 8 and 9, but in either case, it is sufficient if it is possible to fold through this portion, and for example, so-called perforation processing or crease processing may be used.

[0045] For example, in the example of Fig. 9, since the divided parts are formed at the upper and lower positions of the foreign body capture part through the die-cut part, if the adhesive layer in this state is stepped on, there is a concern that the upper and lower divided parts will stick to the sole of the shoe and be lifted up unless it is firmly fixed to the floor surface. This problem can be solved by the following simple method. For example, as shown in Fig. 9, a preferred embodiment is to use 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 to make the rod-shaped protrusions recessed, so that the divided parts can be fixed at the upper and lower positions by moving the position of the rod-shaped protrusions when used.

[0046] (Measures to prevent 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, and 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 having 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 a frame-like structure formed of a frame 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 a state where the laminated adhesive mat is integrated with 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).

[0047] In the above configuration, the frame provided on the support as the sticking prevention member does not necessarily have to be in the shape of a picture frame. For example, a method of providing a long member that is higher 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 picture frame illustrated in Fig. 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 Fig. 1, or may be provided on either member 1 or member 2 of the support as described above.

[0048] 2 and 3, it is also effective to provide a plurality of protruding members (protrusions) higher than the height of the adhesive surface, which is the outermost surface of the divided portion of the foreign body capture section, on both members 1 and 2 of the support as anti-sticking members, at positions facing each other when folded. In this way, when the foreign body suction / capture device of the present invention is folded so that the adhesive surfaces face each other (face each other), 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 functioning as anti-sticking members may be provided on either member 1 or member 2 of the support.

[0049] In either case, by providing the sticking prevention member, when the foreign matter adsorption and capture device of the present invention is folded and the adhesive surfaces are opposed to each other (face to face), the sticking prevention members come into contact with each other earlier than the adhesive surfaces come into contact with each other, or the sticking prevention members come into contact with the opposing surfaces of the support, so that the adhesive surfaces can be effectively prevented from sticking to each other. Note that the shape of the sticking prevention member used in the present invention, and the position and number of the sticking prevention members to be provided 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 opposed to each other.

[0050] 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 releasable 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. Therefore, 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 carried, the release sheet may come off from between the opposing adhesive surfaces, making it impossible to avoid the adhesive surfaces from sticking to each other.

[0051] As a method for solving the above-mentioned problems, for example, the release sheet may be integrated into the foreign matter adsorption / capturing device as described below. For example, as shown in Fig. 10 and Fig. 11, the support may be a tri-fold type consisting of three divided parts, two adjacent divided parts may hold a laminated adhesive mat, and the front and back surfaces of the remaining divided part may be formed of a material having releasability or a material that has been treated for release, so that the divided part that has the function of a release sheet is not lost during use or transportation, since it is integrated into the foreign matter adsorption / capturing device without coming off even during use, as shown in Fig. 11.

[0052] The foreign object adsorption / capturing device of the present invention can also be folded 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, as shown in FIG. 8. In this case, the outermost adhesive surfaces of the divided parts do not face each other and stick to each other, but the outermost adhesive 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 the sticking that occurs in this case, it is preferable to prepare a dedicated storage device and store the foreign object adsorption / capturing 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 / capturing device of the present invention is folded and stored in the storage device with the outermost adhesive 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 is configured to have releasability. Specifically, a method can be used in which the inner surface of the box or bag of the storage device is made releasable, or at least one surface of the furoshiki-shaped one is made releasable.

[0053] Specifically, it is preferable that the inner surface of the box of the storage tool is formed from release paper. As the release paper, paper such as fine paper, flat paper, craft paper, glassine paper, synthetic paper, etc., which has at least one surface with a release treatment, or plastic film, etc. can be used. Furthermore, when the storage tool is a bag or wrapping cloth-like object, in addition to the materials listed above, for example, uneven fabrics with a reduced contact area, plastic materials such as nylon, or cloths or nonwoven fabrics with at least one surface with a release treatment can be used.

[0054] The size and shape of the foreign matter adsorption / capturing device of the present invention may be appropriately determined depending on the purpose of use and the place where it is installed, and are not particularly limited. The important point in the present invention is 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, the shape of the laminated adhesive mat when unfolded may be a polygonal shape such as a rectangle, a square, or a trapezoid, or a circle, an ellipse, or a cloud shape, with a short side of about 10 cm to 90 cm and a long side of about 10 cm to 200 cm. It may be appropriately designed in consideration of folding. For this reason, the shapes of the multiple divided parts of the foreign matter capture part constituting the laminated adhesive mat do not necessarily need to be the same, and may be appropriately designed in consideration of folding and the purpose of use.

[0055] The foreign object suction 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 such facilities include gymnasiums, various classrooms, rental conference 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 become more diverse. In various situations, importance is placed on measures to prevent foreign objects from entering objects when making things, consideration for exhibits, and prevention of injuries during competitions and practice. The foreign object suction capture device of the present invention, which is easily portable, can meet the diverse needs of various people.

[0056] In recent years, hay fever has become a problem, and people are reluctant to bring these foreign objects into their homes and individual 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 that it can 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, and 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, so that it is easy to provide a product with excellent design. Specifically, a non-transparent sheet-like member is used as the base part, and the image is printed directly or transferred onto this sheet-like member, or the non-transparent base part having a colored part with an image and the foreign object capture part are integrated, and a printed matter is placed between them, thereby making it possible to easily provide a product with excellent design. Specifically, the substrate part can be formed by using a non-transparent sheet-like member, and printing is performed directly or by transferring the image onto the sheet-like member, or by integrating the non-transparent base part having a colored part with an image and the foreign object capture part, and placing a printed matter between them.

[0057] 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, non-oriented 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 contents of the printed letters or images can be easily and freely made diverse, and therefore the visual effect can be improved.

[0058] The use of the foreign matter adsorption and capture device of the present invention can be considered as a foot-operated laminated adhesive mat, which has been described 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 become a problem during various tasks. When used as a foot-operated laminated adhesive mat, it is preferable to fix it firmly to the floor surface at the entrance of a facility such as a gymnasium so that it can be placed there. When used for the purpose of adsorbing and removing foreign matter on fingertips, it is preferable to fix it to a desk or a wall surface so that it can be placed there. As a method of fixing it to a floor surface or a wall surface, a fixing part made of a non-slip material described later or an adhesive part made of an adhesive that can be firmly fixed and is peelable can be provided on the surface of the support constituting the present invention that is not provided with the laminated adhesive mat, as will be described later.

[0059] The adhesive part for fixing the foreign object adsorption and capture device of the present invention to a floor or wall must be firmly fixed to the floor, especially when used as a stepping-type laminated adhesive mat, because it is a product that encourages people to step on it. For this purpose, it is preferable to form the adhesive part for fixing to the floor 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 part having the above-mentioned strength. It is also preferable to select and use an adhesive that does not leave any adhesive residue when the foreign object adsorption and capture device of the present invention is peeled off from the floor.

[0060] 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, diene rubber such as CR or SBR, non-diene rubber such as butyl rubber, EPDM, or various sponges such as urethane sponge is arranged between the floor surface and the foreign object adsorption and capture device.
