Description

The present invention relates to a laminated adhesive mat for removing dust, and for example, adheres foreign substances such as sand, dust, and dust that adhere to the human body, clothes, and shoes and are brought in from the outside, which are avoided in facilities such as gymnasiums and manufacturing factories. In the adhesive mat for capturing on the adhesive surface, in particular, by adopting a configuration in which the visual enlightenment effect is positively improved, for example, the foreign matter is more sufficiently adsorbed or dropped on the adhesive surface. The present invention relates to a laminated adhesive mat product for dust removal having a structure capable of capturing foreign matter more sufficiently.

Conventionally, by riding on a mat having an adhesive surface, sand and dust adhering to footwear such as soles are adsorbed, and foreign substances such as dust and dirt adhering to clothing and the human body are dropped. Foot-operated adhesive mats that capture foreign matter on the adhesive surface are widely known and are also used. In addition, various proposals have been made for products with enhanced convenience. For example, Patent Document 1 proposes a dust-removing mat having a structure in which a desired number of sheets provided with an adhesive layer having a specific surface adhesive strength are laminated on paper or a non-woven fabric. This dust removal mat is configured so that when the adhesive layer on the surface becomes dirty due to dust adsorption, it can be peeled off to expose a new adhesive layer for use. Further, for example, in Patent Document 2, by making the constituent material of the base film and the adhesive constituting the pressure-sensitive adhesive film laminated on the base film unique, further functions are added and the antistatic performance is enhanced. A laminated adhesive mat for dust removal has been proposed.

Adhesive mats with the above configuration are extremely simple in configuration, easy to use, and do not use any special equipment or power, so they are widely used in facilities such as gymnasiums and manufacturing factories, for example. There is. By using the above adhesive mat, for example, during competitions and practice such as basketball, volleyball, badminton, futsal, etc. held in the gymnasium, sand and dust that adhered to shoes, human body and clothes and invaded the gymnasium, It is possible to prevent an exercising person from slipping or injuring in some cases caused by foreign matter such as dirt. In the manufacturing factory, by using the above-mentioned adhesive mat, the cleanliness of the manufacturing site is promoted, and the quality of the manufactured product can be improved.

In particular, the adhesive mat having a laminated structure in which a desired number of sheets provided with the adhesive layer are laminated is as simple as peeling off one dirty sheet when the surface of the adhesive layer becomes dirty by capturing foreign matter. Since the surface of the new adhesive layer can be exposed by a simple operation, it is possible to capture foreign matter on the adhesive surface in a good condition at all times. Therefore, for example, by using it according to the state of dirt on the surface or while performing an operation of exposing the surface of the new adhesive layer for a fixed period, it can be continuously fixed for a long period of time, and in some cases, immovable. It is used as if it were a thing.

Japanese Unexamined Patent Publication No. 60-122536 Japanese Patent No. 2939431

As a result of examination by the present inventor with respect to the usage situation of the adhesive mat having the above-mentioned laminated structure, it has been found that there is room for the following improvement. That is, as described above, an adhesive mat for removing dust (hereinafter referred to as a laminated adhesive mat) having a laminated structure in which a desired number of adhesive sheets provided with an adhesive layer are laminated is used in facilities such as gymnasiums and manufacturing factories. Since it will be placed at the entrance for a long period of time, its impression is weak and its presence is almost nonexistent. It was found that foreign substances such as sand, dust, and dust brought in from the above could not be sufficiently adsorbed or dropped on the adhesive surface of the laminated adhesive mat to be captured.

That is, even if the present inventor installs a conventional laminated adhesive mat at the entrance of a facility such as a gymnasium or a manufacturing factory, the impression is thin, and the adhesive mat gives visitors a "human body, clothing, etc." I couldn't make a strong impression that it was intended to remove foreign matter such as sand, dust, and dust that adheres to shoes and is brought in from the outside. It was recognized that the purpose of the period was not fully achieved. For example, as observed by the present inventor, when the laminated adhesive mat is placed on the floor, the visitors often do not take the action of sufficiently stepping on the laminated adhesive mat for dust removal. It was found that foreign substances were brought into gymnasiums and manufacturing factories. In addition to the foot-operated laminated adhesive mat in which a person stands on the mat, dust and dirt adhering to fingertips and clothes due to static electricity, etc., are not washed away with water, for example, a small laminated adhesive placed on a desk. It would be extremely useful if it could be removed by adsorbing it on the adhesive surface of the mat.

Therefore, an object of the present invention is the above-mentioned stepping type laminated adhesive mat that is continuously installed for a long period of time, and the object of the present invention is "sand, dust, dust, etc. that adhere to shoes, a human body, or clothing and are brought in from the outside." The purpose is to improve the structure so that "dust removal of foreign matter" can be sufficiently achieved. In addition, an object of the present invention is to make full use of the function of the visitors by taking a device to actively take the action of sufficiently stepping on the stepping type laminated adhesive mat. It is to improve the structure so that it can be used. Furthermore, an object of the present invention is to give a strong message to visitors who share a sense of value and behavior because the place where the laminated adhesive mat is installed is a facility such as a gymnasium or a manufacturing factory. The purpose is to find a means capable of enhancing the presence of the laminated adhesive mat and to improve the configuration so that the function of the laminated adhesive mat can be more fully exhibited. Furthermore, considering a new application such as removing dust and dirt adhering to fingertips and clothes due to static electricity by adsorbing it on the adhesive surface of a laminated adhesive mat without washing it with water, for example, on a desk or the like. Since it is desired to provide a laminated adhesive mat that gives a smart impression without discomfort when placed, it is an object of the present invention to provide such an improved laminated adhesive mat.

The above object is achieved by the following invention. That is, according to the present invention, [1] when removing foreign substances such as sand, dust, and dust, a plurality of laminated adhesive sheets are sequentially peeled off to expose a new adhesive surface for dust removal. The pressure-sensitive adhesive sheet has a transparent base material having a releasable thickness of 10 μm to 200 μm on one surface and a thickness formed on the non-releasable surface of the base material. It is a transparent pressure-sensitive adhesive sheet composed of a transparent pressure-sensitive adhesive layer of 1 μm to 200 μm, and a plurality of the transparent pressure-sensitive adhesive sheets are in contact with each other in a state where the releasable surface of the transparent base material and the pressure-sensitive adhesive layer are in contact with each other. It has a transparent foreign matter catching part formed by laminating the sheets and a non-transparent base material part for holding the foreign matter catching part, and the foreign matter catching part and the non-transparent base material part are peeled off. The non-transparent base material portion, which is integrated into a possible state or a non-peelable state, is provided with a colored portion having an image, and the image is taken from the transparent foreign matter trapping portion side. Provided is a laminated adhesive mat for dust removal, which is configured to be visible and is provided with the visual effect of the image.

Preferred forms of the adhesive mat for dust removal of the present invention include the following.
[2] The non-transparent base material portion is a non-transparent sheet-like member having an adhesive portion or a non-slip member for fixing to a floor surface or a fixing mat, and the colored portion holds the adhesive portion. Consists of a printed matter having letters and / or figures applied to a white or colored plain surface on the non-existent side, or a printed matter having letters and / or figures placed and held on the non-transparent sheet-like member. The dust removal according to the above [1], wherein the image formed by the printing or the image of the printed matter can be visually recognized through a plurality of laminated adhesive sheets constituting the transparent foreign matter trapping portion. Laminated adhesive mat for.

[3] The laminated adhesive mat for dust removal according to the above [2], wherein the image includes a content that calls attention to a stepping action on the foreign matter trapping portion.
[4] The laminated adhesive mat for dust removal according to the above [2] or [3], wherein the image includes any of a display that serves as a message to the user, a display related to the user, and a display related to the user.
[5] The laminated adhesive mat for dust removal according to the above [1] to [4], which has a structure that can be folded into at least two or more.

According to the present invention, there is provided a foot-operated laminated adhesive mat for dust removal that can sufficiently achieve "dust removal of foreign substances such as sand, dust and dust that adhere to shoes, a human body or clothing and are brought in from the outside". To. Specifically, the visual effect of the image of the colored part that constitutes the product can further enhance the effect of capturing foreign substances such as sand, dust, and dust, and when the product is stepped on for a long period of time. However, since the visual effect can be maintained without impairing the sharpness of the image, according to the adhesive mat of the present invention, it is possible to further enhance the effect of capturing foreign substances such as sand, dust and dust. Of course, it is also possible to raise the awareness of users who try not to bring in foreign substances, so it is possible to suppress the invasion of foreign substances into facilities such as gymnasiums and manufacturing factories at a high level. Further, the effect of the present invention is more effective by giving a strong message or pattern including a content that calls attention to be sure to step on the foreign matter trapping portion as an image possessed by the colored portion constituting the product. It will be something like that. In addition, if the image of the colored part that composes the product is made to give a strong message to the visitors (users) who share the sense of value and behavior, the dust removal effect required for the above-mentioned product itself can be obtained. In addition to the improvement, it is also possible to unify the intentions of visitors who use facilities such as gymnasiums and manufacturing factories by visual stimulation.

Further, according to the present invention, for example, when placed on a desk or a wall, a laminated adhesive mat that does not give a sense of discomfort, has excellent design, and in some cases has a message can be provided. Dust and dust adhering to clothing etc. can be easily removed by adsorbing it on the adhesive surface of the laminated adhesive mat placed on the desk or wall, which is not found in the conventional foot-operated laminated adhesive mat. The usage mode can be realized.

Furthermore, according to another embodiment having a structure that can be folded into at least two or more, the laminated adhesive mat of the present invention makes it much easier to carry, so that the conventional use in a form in which the laminated adhesive mat is permanently installed. In addition, it will be possible to provide products that are versatile enough to be carried and used. As a result, groups and individuals who use facilities such as gymnasiums can easily bring in and use laminated adhesive mats, so foreign substances such as sand, dust, and dust brought in from the outside can be used as adhesives. It is extremely useful because it allows you to ensure your own safety when playing or practicing in a gymnasium that does not have an adhesive mat for capturing on the surface. Further, by using the laminated adhesive mat having a structure that can be folded into at least two or more according to this other embodiment, for example, when it is used while being placed on a desk or a wall, it is folded in half when it is not used. When it is necessary to prevent the adhesive surface from being exposed and to adsorb dust or dirt adhering to fingertips or clothing, the adhesive surface can be exposed and the design is excellent. Since it can be easily made into a product, it becomes a more useful product that matches the purpose and situation of use.

To illustrate an example of a configuration in which an ink receiving layer is provided on the adhesive sheet side of a non-transparent sheet-like member holding a transparent foreign matter trapping portion, which constitutes the laminated adhesive mat for dust removal of the present invention, and an image can be printed. It is a schematic cross-sectional view of.

It is a perspective view which shows typically the laminated adhesive mat for dust removal of this invention. It is a perspective view which shows typically the laminated adhesive mat for dust removal of this invention of a structure which can be folded in two.

Hereinafter, the present invention will be described with reference to preferred embodiments. Based on the above recognition, the present inventor investigated the configuration of the conventional stepping type laminated adhesive mat, and as a result, in the type in which a plurality of adhesive sheets are laminated, it is easy to identify the adhered foreign matter and the case becomes dirty. It was found that each laminated adhesive sheet is composed of a plain white material for the purpose of facilitating the judgment of exposing a new adhesive surface. In a clean room with little dirt, a plain blue product may be used. For example, the dust removal mat described in Patent Document 1 mentioned above has an adhesive layer provided on paper or a non-woven fabric. Then, the product name and the like are displayed on the cover of the laminated adhesive mat with a cover. A type of resin adhesive mat that does not stack adhesive sheets is also known. Most of this type of product is plain colored with a color such as blue or green, but it is usually plain white.

As described above, in the conventional foot-operated laminated adhesive mat, the present inventor can judge the dirty state of each laminated adhesive sheet as a common technical knowledge for continuously performing dust removal in a good state. The most important point in the laminated adhesive mat is not to make it easy to judge when to expose a new adhesive surface, but to make it on the laminated adhesive mat, as opposed to the fact that it is composed of plain colors such as easy white and blue. , Visitors should "more reliably remove foreign substances such as sand, dust, and dust that adhere to shoes, human bodies, and clothing and are brought in from the outside," that is, visitors to facilities such as gymnasiums and manufacturing plants. It was recognized that the original purpose of the foot-operated laminated adhesive mat would be effectively exerted by more actively obtaining the cooperation of.

Based on the above recognition, the present inventor cooperates with visitors to facilities such as gymnasiums and manufacturing factories to "remove foreign substances such as sand, dust, and dust that adhere to shoes, human bodies, and clothing and are brought in from the outside." We enthusiastically examined the means by which we could encourage them to do so. As a result, the foot-operated laminated adhesive mat is a product with a wide surface, and by taking advantage of this point, visitors naturally "sand that adheres to shoes, the human body, and clothing and is brought in from the outside." We have found that it is effective to visually encourage them to cooperate in "dust removal of foreign substances such as dust and dirt."

Specifically, the individual adhesive sheets that make up the foot-operated laminated adhesive mat are a plain white base on which one side is released from the mold in order to make it easier to determine the degree of dirt due to use in conventional products. A pressure-sensitive adhesive layer was formed on the material. Even in products that are not plain white, plain base materials such as blue were used. The present inventor overturns this common general knowledge, makes each adhesive sheet a transparent body, and by stacking a plurality of transparent adhesive sheets to form a transparent body, the foreign matter trapping portion is made a transparent body, and the foreign matter trapping portion is fixed and held. It has been found that it is effective to solve the above-mentioned problem of the present invention to configure the colored portion provided on the non-transparent base material portion so as to be visible from the transparent foreign matter trapping portion side. That is, if a foot-operated laminated adhesive mat is configured as described above and a message or a pattern is provided on a non-transparent base material portion having a wide surface, these can be visually recognized from the transparent foreign matter trapping portion side, and the meaning and content thereof. It will be an unprecedented configuration that can be understood immediately.

Furthermore, the present inventor is an opaque sheet having an adhesive portion or a non-slip member for fixing a non-transparent base material portion for fixing and holding a foreign matter trapping portion to a floor surface or a fixing mat. A colored portion composed of a shaped member and having a message or a pattern provided on the base material portion is directly printed on the side surface having no adhesive portion, or the side having no adhesive portion. It was found that the following effects can be obtained by placing and holding a printed matter with a message or a pattern on the surface of the surface. In this case, as shown in FIG. 1, it is preferable to use an opaque sheet-like member having an ink receiving layer on the surface.

Then, the above message or pattern should be displayed so that the visitors can re-recognize the original purpose of installing the laminated adhesive mat at the entrance of facilities such as gymnasiums and manufacturing factories, and the contents can be understood instantly. For example, it was confirmed that visitors will naturally and actively cooperate in "removing foreign substances such as sand, dust, and dust that adhere to shoes, human bodies, and clothing and are brought in from the outside." And, as a side effect, those who have experienced the above can raise their awareness to prevent foreign substances from being brought into facilities such as gymnasiums and manufacturing factories, so even before getting on the laminated adhesive mat, garbage It turned out that we will try not to bring foreign substances to the site. As a result, by installing the laminated adhesive mat of the present invention, the visitors can sufficiently step on the laminated adhesive mat of the stepping method and drop the deposits, and catch dust and foreign matter. The effect can be further enhanced, and further, due to changes in visitors' awareness of bringing garbage and foreign substances into facilities such as gymnasiums and manufacturing factories, it is possible to prevent more garbage and foreign substances from being brought into the facility. I understood.

Examples of the above-mentioned effective message include the following character display. Then, it is also a preferable form to display a foot shape as shown in FIG. 4 or 5, a pattern conscious of stepping, a pattern calling attention, and the like together with or independently of these messages. In particular, since the design can be understood by people all over the world, in the modern age of internationalization, it can be possible to instantly understand the purpose of installing the laminated adhesive mat, rather than a text message. You should use it positively.

・ "Step here!"
・ "Stepping on! 1, 2, 3, 4, 5"
・ "No garbage intrusion"
・ "STOP! Start stepping on!"
・ "STOP! DO YOUR BEST"

By installing the stepping-type laminated adhesive mat of the present invention, it is possible to encourage the active cooperation of the visitors in preventing dust and foreign matter from being brought into the site. Further, the content of the message or the pattern of the colored portion constituting the laminated adhesive mat of the present invention is set according to the individual purpose of use of the facility to be installed, a display related to the user, a display related to the user, or the like. This can also induce another visual enlightenment effect on the user of the laminated adhesive mat, which is a visitor to the facility.

Specifically, in the case of a gymnasium competition, for example, if the foot-operated laminated adhesive mat of the present invention to be installed is displayed with the following message, the visitors' awareness of victory, etc. You can also expect a visual effect to improve.

・ "Don't step on and slip, grab the victory!"
・ "NO STEP NO WIN"
・ "Winning! ●● High School"
・ "Weak / Weak Sound GOODBYE"
・ "NO BASKETBALL NO LIFE"

Further, the content of the message or the pattern of the colored portion constituting the laminated adhesive mat of the present invention is, for example, an individual group name or an athlete, which is a display related to or related to a user who is competing or practicing in a gymnasium. By displaying the name and other information and information about the competition, it is possible to make a laminated adhesive mat that the user uses as a special product, which is different from the laminated adhesive mat of public objects installed in gymnasiums and the like. .. The laminated adhesive mat of the present invention can also be used as, for example, a prize for a competition or a participation prize. In that case, by adjusting the content of the message or pattern appropriately, it is possible to effectively prevent foreign substances such as sand, dust, and dust from being brought into the gymnasium when the laminated adhesive mat is used. In addition to being able to do this, it can be expected to improve the user's attachment to the competition and the organization to which he belongs.

In contrast to the above-mentioned stepping-type laminated adhesive mat having the configuration of the present invention, the conventional product has an adhesive layer on a base material such as a plain white or dark blue plain in which one side of each adhesive sheet is released. Therefore, it is considered that the same visual effect can be expected by printing the above-mentioned message or pattern on a base material such as plain white or plain blue. However, in this case, it becomes necessary to print individually on each base material of each pressure-sensitive adhesive sheet, and the structure is not as simple as that of the present invention. In addition, in conventional products, the base material of each adhesive sheet is often plain white, so the degree of dirt on the used surface becomes clearer, and the message or pattern becomes difficult to see due to dirt, and with use. There is also the problem that the visual effect is lost, which is difficult to realize.

On the other hand, in the stepping type laminated adhesive mat of the present invention, a message or the like is printed on the ink receiving layer on the surface of the opaque sheet-like member with the structure of the non-transparent base material portion for holding the foreign matter trapping portion. This can be achieved extremely easily because it is sufficient to form a colored portion by forming a colored portion or separately prepare a printed matter on which a message or the like is printed and arrange this as a colored portion on the surface of an opaque sheet-like member. Further, in any of the above-described embodiments, the foreign matter trapping portion formed by laminating a plurality of adhesive sheets, which are fixed, held and integrated with the non-transparent base material portion, is transparent, and therefore, each adhesive sheet. Compared to the conventional foot-operated laminated adhesive mat that uses a plain white base material, the dirt on the surface with dust and foreign matter is less noticeable, so even at the stage of renewing the dirty adhesive sheet, a message or The visual effect of the pattern can be maintained. Further, in the laminated adhesive mat of the present invention, when dust or foreign matter accumulates on the adhesive surface and the visual effect is weakened, a new adhesive surface appears by peeling off one dirty sheet to make a new adhesive sheet. Every time the dirty adhesive sheet is renewed, the message or pattern of the colored part becomes clearer, so that the effect of capturing foreign substances and the visual effect can be continuously obtained.

In particular, according to the laminated adhesive mat of the present invention in the form of using printed matter, it is expected that different visual effects will be exhibited by changing the message when all the adhesive sheets constituting the foreign matter trapping portion are used up or during use. In this case, the laminated adhesive mat of the present invention can be easily obtained by arranging a printed matter displaying a new message or the like on the base material portion and installing a new foreign matter trapping portion for replacement in that state. .. In this way, the content of the message or pattern intended for the above-mentioned visual effect can be adjusted in a timely manner according to the situation of facilities such as gymnasiums and manufacturing factories that do not want to bring dust and foreign substances inside. Therefore, a larger visual effect can be expected. The printed matter may have a thickness of about 10 μm to 1 mm, such as a sticker or a printed matter for advertising.

The foot-operated laminated adhesive mat of the present invention is preferably installed near the entrance of a facility where dust and foreign matter are not to be brought into the mat. Facilities include factories, gymnasiums, and houses. More specifically, food manufacturing, pharmaceutical manufacturing, food packaging material manufacturing, various material manufacturing, electronics, electricity, semiconductors, automobile manufacturing and other factory buildings, gymnasiums, general housing, apartment buildings, office buildings, etc. can be considered.

As mentioned above, in recent years, countermeasures against foreign matter contamination at various manufacturing sites and prevention of injuries in gymnasium competitions have become more important, and product development with a higher installation effect of laminated adhesive mats is eagerly desired. The foot-operated laminated adhesive mat of the present invention is an effective product that meets such demands in the field. In recent years, pollinosis has become a problem, and even in houses, bringing in these foreign substances has been avoided, and the demand for them is increasing. In this case, it is important to improve the design, but the colored portion constituting the laminated adhesive mat of the present invention can easily change the image such as a message or a pattern, so that the design is suitable for each house or the like. It is possible to easily provide excellent products.

In the laminated adhesive mat of the present invention, as described above, the transparent foreign matter trapping portion and the non-transparent base material portion for holding the foreign matter trapping portion and fixing it to the floor surface can be peeled off. It is integrated in a non-peelable state, and in particular, each adhesive sheet is transparent, and a foreign matter trap portion formed by laminating a plurality of these adhesive sheets is made a transparent body, and the transparent body is transparent. It is characterized in that it is configured so that a colored portion consisting of a message or a pattern provided on a non-transparent base material portion can be visually recognized.

Therefore, the pressure-sensitive adhesive sheet constituting the laminated pressure-sensitive adhesive mat of the present invention is formed by forming a highly-performance pressure-sensitive adhesive layer on which foreign matter such as dust adheres to a highly transparent film, and a plurality of these are laminated. It is necessary that the foreign matter trapping part becomes a transparent body. Therefore, it is preferable to form individual pressure-sensitive adhesive sheets with the following materials.

As the transparent base material of the pressure-sensitive adhesive sheet, a transparent plastic film having a thickness of about 10 μm to 200 μm, preferably about 30 μm to 60 μm, and one surface having releasability is used. The transparency in this case is such that the number of laminated sheets is gradually reduced by peeling off the adhesive sheets one by one and using them. Therefore, for example, when about 30 to 60 adhesive sheets are laminated to form a foreign matter trapping portion. The image of the non-transparent base material portion may be visible from the foreign matter trapping portion side. In addition, since it is used to encourage the user to step on and step on it, a material having excellent strength is used. Specifically, for example, polyvinyl chloride, polyester, polypropylene unstretched film (CPP), polypropylene stretched film (OPP), polyethylene, polyamide (nylon: registered trademark), synthetic paper and the like can be used. Among these, polyester, polyethylene and the like are preferably used in consideration of strength and environmental load when discarded. The adhesive sheet constituting the laminated adhesive mat for dust removal of the present invention is made into a product in a state where a plurality of sheets are laminated and is peeled off one by one at the time of use. Therefore, one surface of the transparent base material is releasable. Use one that has.

Any of the pressure-sensitive adhesives conventionally used for producing the pressure-sensitive adhesive sheet can be used for forming the pressure-sensitive adhesive layer formed on the surface of the pressure-sensitive adhesive sheet. For example, any of conventionally known adhesives such as acrylic type, rubber type, hot melt type, emulsion type, urethane type, and silicon type can be used. What is important in the present invention is to select and use a pressure-sensitive adhesive that makes the formed pressure-sensitive adhesive layer excellent in transparency. The thickness of the pressure-sensitive adhesive layer may be about 1 μm to 200 μm, preferably about 2 μm to 60 μm, more preferably about 2 μm to 30 μm, and this point is not different from the conventionally known pressure-sensitive adhesive sheet. ..

In the laminated adhesive mat of the present invention, as shown in FIG. 1, the transparent adhesive sheets configured as described above are separated from each other by the transparent adhesive sheet having a releasable surface and another transparent surface. A plurality of sheets are laminated in contact with the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet to obtain a transparent foreign matter trapping portion. The number of sheets to be stacked is not particularly limited. For example, in consideration of convenience, it is assumed that the dirty adhesive sheet is peeled off and replaced with a new adhesive surface every day, and about 30 sheets are used for one month. Also, for example, for events held in gymnasiums, people come and go frequently, so it is necessary to replace it in a short time, so the adhesive sheet laminated in the above state should be used up in one day. , A form in which several to 10 sheets or about 15 sheets are laminated is also useful. In this case, as mentioned earlier, the visitors (users) actively cooperate in "removing foreign substances such as sand, dust, and dust that adhere to shoes, the human body, and clothing and are brought in from the outside." It is also preferable to have a configuration in which a message related to the event is displayed in addition to the message to be displayed. In order to ensure that the laminated adhesive sheets are peeled off one by one and used, a part of each adhesive sheet should be numbered so that the number of stacked adhesive sheets can be instantly known. Is also a preferred form. Further, at the same time as numbering, a numbered portion where the adhesive layer is not formed is provided at the edge of the adhesive sheet so that the laminated adhesive sheets can be easily peeled off to expose the next adhesive sheet. It is also preferable to form. Of course, in the unnumbered embodiment, it is also preferable to provide a portion where the pressure-sensitive adhesive layer is not formed on a part of the edge of the pressure-sensitive adhesive sheet.

As shown in FIG. 1, the laminated adhesive mat of the present invention has a transparent foreign matter trapping portion formed by laminating a plurality of the above-mentioned transparent adhesive sheets and a non-transparent base material portion for holding the foreign matter trapping portion. Is integrated into a state in which it can be peeled off or a state in which it cannot be peeled off. The method of integration is not particularly limited. For example, an adhesive for a transparent adhesive sheet located on the surface of the non-transparent base material on the side where the colored portion is provided, or at the bottom of the laminated transparent adhesive sheets constituting the foreign matter trapping portion. A method of providing a transparent adhesive layer over the entire surface or a part of the surface on the side where the layer is not provided and adhering and integrating using the adhesive layer, or a transparent double-sided tape. The surface of the non-transparent base material portion provided with the colored portion and the surface of the transparent adhesive sheet located at the lowermost stage constituting the foreign matter trap portion not provided with the adhesive layer. Any method may be used, such as a method of adhering and integrating with.

The non-transparent base material portion constituting the laminated adhesive mat of the present invention will be further described. What is important in the present invention is that, as shown in FIG. 4, when the product is used, a colored portion that can be visually recognized from the foreign matter trapping portion side is provided on the non-transparent base material portion. Examples of the method for forming the colored portion include printing on a non-transparent sheet-shaped member or arranging a printed matter on the non-transparent sheet-shaped member.

It is preferable to use the non-transparent sheet-like member described above in the non-transparent base material portion constituting the laminated adhesive mat of the present invention. As the material for forming the non-transparent sheet-like member, for example, a sheet-like or plate-like material such as plastic, paper, wood, or rubber can be used. Examples of the plastic include general-purpose materials such as polyvinyl chloride, polypropylene, polystyrene, polycarbonate, and ABS resin. The sheet-shaped member made of these materials is provided with a means for fixing the transparent foreign matter trapping portion having the above-described configuration on the surface on the side where the colored portion is provided and integrating the transparent foreign matter trapping portion for firmly holding the portion. It may have been. As a means for fixing the foreign matter trapping portion to the non-transparent base material portion and integrating the foreign matter trapping portion firmly, there is a method of adhering with a transparent adhesive as described above. The thickness of the non-transparent base material varies depending on whether it is placed on the floor as it is or on the floor via a dedicated fixing mat, but is preferably 1 to 20 mm, for example. It is about 2 to 20 mm, more preferably about 2 to 20 mm.

In the laminated adhesive mat of the present invention, the surface of the non-transparent base material portion that fixes and holds the foreign matter trapping portion is usually fixed to the floor surface, the wall surface, or the like, or a dedicated fixing described later. Used by fixing to a mat.
