Conventionally, in a mat of this type used in a clean room or the like, a multi-layer mat in which a thin plastic film containing an antibacterial agent coated with an adhesive is laminated in several layers is stored in a rubber or plastic frame. Although a dust removal mat is known, this dust removal mat has a germicidal and dust removing effect at the initial stage of installation, but the germicidal and dust removing effect gradually decreases due to dust attached when passing through people and trolleys. I do. For this reason, the film must be turned over quite frequently, and this operation is not only troublesome, but also has a drawback that the mat surface layer is not wet and thus has a dust-removing effect but a weak sterilizing effect.

In order to solve the above-mentioned drawbacks, a special frame divided into three as shown in Utility Model Registration No. 3002095 is separately prepared, and a polymer foam sheet is provided in a storage portion at the center of the frame. Or store artificial grass,
There is a sterilization mat that contains a water-absorbent sheet on the front and back,
However, this disinfecting mat has a practical problem such as a rapid transpiration of water and the need to repeatedly supply water.
In addition, this sterilization mat requires the use of a specially prepared mat frame prepared separately for installation, and also has a disadvantage that a difference in height is easily generated between the frame and the floor surface, which causes a tripping in walking or transportation.

The present invention has the above-mentioned problems of the prior art, that is, the trouble of turning over the film one by one, the trouble of replenishing water repeatedly, the inconvenience of using a specially made frame, and the inconvenience of using a frame. It is an object of the present invention to obtain a water-retentive sanitizing mat which eliminates disadvantages and the like which are easily tripped off and which can obtain a certain sterilizing effect.

FIG. 6 shows another embodiment of the first aspect of the present invention. The water-retentive sanitizing mat of the present invention shown in FIG. 6 is different from that shown in FIG.
Are present only on the entire surface.

One embodiment of the second aspect of the present invention, that is, an embodiment in which a water leakage preventing material encloses a water retaining layer and a surface layer will be described with reference to FIGS. 7 is a perspective view, and FIG. 8 is a line VI in FIG.
FIG. 8 is a cross-sectional view taken along the line II-VIII, and the same reference numerals are given to the same or corresponding parts as in the embodiment shown in FIGS. In the figure, reference numeral 6 denotes a water-permeable substance provided in the water supply port 5. Although the water leakage prevention member 2 is fixed to the outer peripheral portion of the surface layer 4 by the fixing layer 3, it may be fixed to the outer peripheral portion of the surface by pressing from above with a tape or the like (not shown) instead of the fixing layer. When the water retaining layer 1 and the surface layer 4 are overlapped and sealed in the water leakage prevention material 2, that is, the bag-like material A or the cylindrical material B, the manufacturing process is simplified and the cost is reduced.

FIG. 9 shows another embodiment of the second aspect of the present invention. In the water-repellent sanitizing mat of the present invention shown in FIG. 9, the water leakage preventing material 2 does not cover the outer peripheral portion of the surface layer 4 as compared with those shown in FIGS.

FIGS. 10 and 11 show another embodiment of the second aspect of the present invention. In the water-retentive sanitizing mat of the present invention shown in FIGS. 10 and 11, the water leakage prevention material 2 is not a bag-like material or a cylindrical material, but is folded and wrapped as shown in FIG. In the figure, 14 is an adhesive layer, 15 is a water reservoir, and 16 is a moisture evaporation suppressing cap detachably attached to the water supply port 5.

FIG. 12 shows another embodiment of the second aspect of the present invention. The water-retentive sanitizing mat of the present invention shown in FIG. 12 is different from those shown in FIGS. 10 and 11 in that the water leakage preventing material 2 does not cover the outer peripheral surface of the surface layer 4.

Here, as a base material of the surface layer 4 having pores 7 penetrating up and down as shown in each figure, PET, PE, nylon, PP, PVC, PVC, and the like in the form of a film, a sheet, and a board. Plastics such as urethane, NR,
IR, IIR, CR, SBR, NBR, EPR, BR,
Rubber such as SBS, SIBS, SIS or the like, metal or non-woven fabric is used, and any of them is required to be moisture-impermeable to suppress the evaporation of moisture from the water-retaining layer 1, and the surface can be easily cleaned by washing with water. It is desirable to use a material that falls.

Further, an adhesive layer 14 may be provided on the back surface of the surface layer 4 as shown in FIG. 11 in order to firmly fix the surface layer 4 and the water retaining layer 1, but in this case, the adhesive layer 14
May be any of rubber-based, acrylic-based, vinyl acetate-based, and urethane-based solvent types, aqueous types, hot melt types, and dry types, as long as they do not lose adhesion to adherends containing moisture. The fixing of the surface layer 4 and the water-retaining layer 1 does not necessarily have to be limited to the adhesion between them. For example, heat sealing may be used, as long as the surface layer 4 can be fixed to the water-retaining layer 1 so as not to be turned up when passing. Good.

On the other hand, the vertically penetrating pores 7 provided in the surface layer 4 preferably have a size of 0.02 mmφ to 0.3 mmφ. The reason why such pores 7 are provided in the surface layer 4 is to exude the antibacterial agent aqueous solution from the water retaining layer 1 by treading pressure, and to kill bacteria adhering to the mat contact surface and the mat by the exudate. is there. Here, if the pore diameter of the pores 7 is 0.02 mmφ or less, the pores are too small to cause clogging due to dust and the like, and the aqueous solution from the water retaining layer 1 is not easily oozed.
If the diameter is equal to or more than mφ, the water tends to evaporate from the pores, and the purpose of suppressing the evaporation of the water from the water retaining layer 1 and the water storage portion 15, which is another important function of the surface layer 4, cannot be achieved. When the pressure-sensitive adhesive layer 14 is used for fixing the surface layer 4 and the water retaining layer 1, the pores 7 must naturally penetrate the pressure-sensitive adhesive layer 14.

Further, a water supply port 5 communicating with at least one water retention layer 1 is provided at a desired position (the center in the drawing) of the surface layer 4. The size of the water supply port 5 depends on the water supply port 5 to be provided.
And the volume of the water-retentive sanitizing mat of the present invention to be obtained.
The size of 0cm ² ~1000cm ² are suitable. This is because if the water supply port area is smaller than about 10 cm ^2, it takes too much time to supply water, which is not preferable. If the water supply port area is larger than about 1000 cm ² , it may hinder walking on the mat.

The water supply port 5 has a nonwoven fabric, paper, cotton,
A water-permeable substance 6 such as a cloth, a blanket, a sponge or the like is filled. This is because, if the water supply port 5 is left in a gap, water tends to evaporate from the gap, and dirt and mud are clogged in this hole, which is a source of contamination. The water supply port 5 is provided with a removable moisture evaporation cap 16 made of plastic or rubber on the upper part of the water-permeable substance 6 to be contained, or the removable water evaporation suppression seal tape 8 is a part of the water supply port 5. Or, the surface layer 4 around the water supply port 5 so as to cover the whole.
Is provided via This is to prevent evaporation of excess water from the water supply port 5. Note that the base material of the moisture evaporation suppression seal tape 8 may be any base material having a moisture evaporation suppression function, and for example, the same material as the surface layer 4 may be used.

In each of the drawings, a case is shown in which one water supply port 5 is provided, but a plurality of water supply ports 5 may be provided if necessary. Further, the position of the water supply port 5 is changed to the surface layer 4.
Although the position of the water supply port 5 is not particularly limited to the center, any position may be used as long as water can be supplied smoothly. 2 and 4 to 6, when the lower end of the water supply port 5 is located on the surface of the water retaining layer 1,
8, 9, and 12, the case where the lower end of the water supply port 5 is located substantially at the center of the water retention layer 1 and the case where the lower end penetrates the water retention layer 1 as shown in FIG. 11 are illustrated. 5 may be in communication with the water retention layer 1, and the lower end of the water supply port 5 may be positioned above the water retention layer 1 if the water retention layer 1 can quickly supply the antibacterial aqueous solution or water supplied from the water supply port 5. But it can be in the middle or lower. Furthermore, although the water supply port 5 is illustrated as a rectangle or a circle in the figure, the water supply port 5 is not limited to a rectangle or a circle, but may be a square, a star, a triangle, or the like, as long as the water supply function can be sufficiently performed. It is not particular about the shape.

Next, the water retaining material constituting the water retaining layer 1 will be described. The water retaining layer 1 has a water retaining thickness of 2 mm to 10 mm.
mm of non-woven fabric, cotton, paper, fabric, sponge or blanket or a combination thereof, for example, a laminate. On the other hand, those containing a water-soluble antimicrobial agent in advance can be used for these water retention materials. Furthermore, a water retention material containing no antimicrobial agent and a water retention material containing a water-soluble antimicrobial agent can be used in combination. And, of course,
When using a water retention material containing a water-soluble antibacterial agent,
When a water retention material containing no antimicrobial agent is used, an aqueous solution of the antimicrobial agent prepared in advance is supplied. That is, when the antibacterial agent-containing water retention material is supplied with water, the water-soluble antibacterial agent in the water retention material dissolves in water to form an antibacterial agent aqueous solution. Here, the water retention material is selected to have a water content of at least 1.0 liter to 4.0 liter / m ^{2 in} the above thickness.

On the other hand, the amount of water retention is determined by the thickness and area of the water retention material, but it is usually desirable to select a water retention amount that can be sufficiently used by supplying water once for one to two weeks. In addition, in order to reduce the number of times of water supply, it is assumed that an excessive antibacterial agent aqueous solution or water is supplied to the water retention material,
In the case of such a use example, a form (FIG. 11) in which a water storage portion 15 is provided between the water retaining layer 1 and the bottom surface and an antibacterial agent aqueous solution is temporarily stored therein may be employed.

Here, the aqueous solution of the antibacterial agent to be supplied to the water retaining layer 1 may be any one having an antibacterial property, but in particular, an aqueous solution of benzalkonium chloride of approximately 0.01% to 1.0%, an aqueous solution of benzethonium chloride. , An aqueous solution of alkyl diaminoethyl glycine hydrochloride, an aqueous solution of chlorhexidine gluconate, or an aqueous solution of sodium hypochlorite are recommended from the viewpoint of the bactericidal effect. In addition, water retention layer 1
When a water-soluble antibacterial agent is contained in the antibacterial agent, the above-mentioned antibacterial agent is also selected. In this case, the amount of the water-soluble antibacterial agent contained in the water retention material is such that the concentration becomes approximately 0.01% to 1.0% when a predetermined amount of water is supplied. Needless to say, an antibacterial agent aqueous solution is supplied from the stage when the antibacterial agent is consumed.

Next, the water leakage preventing material 2 which is one of the main parts constituting the present invention will be described.

On the other hand, as shown in FIG. 1 to FIG. 9, the water leakage prevention material 2 is formed by using a bag-like material or a cylindrical material B having a window portion whose surface is substantially the same or slightly smaller. After enclosing only the water retention layer 1 as shown in FIG. 6, or enclosing a laminate of the water retention layer 1 and the surface layer 4 as shown in FIGS. 7 to 9, each opening is sealed and formed. It is. When enclosing the laminated body, a molded product such as a sponge or the like thinner than the laminated body or having a slope shape is simultaneously enclosed around the laminated body or vertically or horizontally to eliminate a step between the mat and the installation surface. You can also. Further, the water leakage prevention material 2 may simply wrap the laminate as shown in FIGS. 10 to 12 without using the bag-like material A or the cylindrical material B.

9 and FIG. 12 show a case where the water leakage prevention material 2 is joined to the entire surface of the surface layer 4 and the side surface of the water retention layer 1 and the outer periphery of the back surface.
FIG. 11 illustrates the case where the water leakage prevention material 2 is joined to the entire surface of the side surface of the surface layer 4 and the water retaining layer 1 and the outer peripheral portion of the surface of the surface layer 4, respectively, but the water leakage prevention material 2 is not limited thereto.
It may be bonded to the entire back surface of the water retaining layer 1 or may be partially bonded to the side surface. Further, when the water leakage prevention material 2 is formed from the bag-like material A or the cylindrical material B, only the opening of the bag-like material A or the cylindrical material B may be joined by heat sealing or the like, or the surface layer 4 may be formed. , May be integrally joined to the water retaining layer 1.

That is, the method of fixing the water leakage preventing material 2 to the back surface or side surface of the water retaining layer 1 and to the side surface or the surface outer peripheral portion of the surface layer 4 is not particularly limited. Any fixing method such as heat shrinkage of the metal or joining with a magic fastener may be used.
Any fixing method may be used as long as the aqueous solution of the antibacterial agent retained in the surface layer 4 does not leak from other than the pores 7 of the surface layer 4. In the case where the surface layer 4 and the water retention layer 1 are firmly held by the water leakage prevention material 2 and the antibacterial agent aqueous solution retained in the water retention layer 1 has a mechanism that does not leak water to the outside, the above-mentioned joining can be omitted.

Next, the method of forming the water-retentive sanitizing mat of the present invention will be described.
Any one of film, sheet, board-shaped plastic, rubber, or non-woven fabric cut into a desired shape formed by providing pores 7 vertically penetrating in the vertical direction of mmφ to 0.3 mmφ as the surface layer 4.

Next, a bag-like material A or a cylindrical material B capable of enclosing only the water-retaining layer 1 or a laminate of the water-retaining layer 1 and the surface layer 4 is prepared, and before or after enclosing them respectively. A window is provided which is substantially equal to or slightly smaller than the surface area thereof, and the opening to be sealed is sealed to form a water leakage prevention material 2, or the width and length are wider than those of the surface layer 4 and the water retention layer 1. The water leakage prevention material 2 is superimposed on the back surface of the water retention layer 1 and is used as a bottom surface, and the excess portion protruding to the outer periphery is bent to the surface layer 4 and the side surface of the water retention layer 1 if necessary, and is adhered thereto. Then, the water leakage prevention material 2 is formed.

Further, the method of applying the water-repellent sanitizing mat of the present invention obtained as described above will be described. The water-retentive sanitizing mat is usually used in hospitals, biochemical factories, food factories, cooking rooms, precision machinery factories. It is installed at the entrance of a clean room such as (e.g., adhered to the floor with the adhesive 10). At the time of this installation, the mat supplies a desired amount of an antibacterial agent aqueous solution or water from its water supply port 5. When water is supplied, a water-retentive sanitizing mat using a water-retaining material containing a water-soluble antibacterial agent is used. In addition, in order to prevent the installation surface from being wet due to condensation or the like, a dew condensation preventing material such as a nonwoven fabric may be attached to the bottom surface of the mat. Then, when a person or a trolley (stretcher) enters and exits the clean room, the antibacterial agent aqueous solution contained in the water retaining layer 1 of the mat is extruded from the pores 7 of the surface layer 4 by the stepping pressure of the person or the trolley (stretcher). So that the surface layer 4 is moistened,
Bacteria adhered to the mat contact surface such as wheels of a trolley (stretcher) and the mat are sterilized and removed. If the surface layer 4 becomes very dirty, the mat surface layer 4 is washed with water, and if necessary, an aqueous solution of an antibacterial agent is supplied and used again. The amount of water supply at one time is approximately 1.0 liter to 4.0 liters, and the amount of water supply is determined according to the frequency of passage of people and bogies, the size of mats to be installed, environmental conditions, and the like. At that time, FIG.
