DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washable mat, and more particularly, to a clean and sanitary washable mat which can be washed while being stored in an outer bag without removing a mat core material from the outer bag.

[0002]

2. Description of the Related Art Conventionally, as a traditional bedding, a futon in which cotton is stored in a cloth bag has been widely used.
It has been pointed out that adverse effects on health due to too softness, and mats made of foamed synthetic resins have become widespread as health mats.

A mat made of a foamed synthetic resin comprises a mat core made of a foamed molded article such as polyethylene and the like, which is housed in an outer bag made of cloth. However, the mat is lightweight, has excellent handleability, and has water repellency. Even if food or food is spilled, it does not penetrate into the inside, and it can be cleaned simply by removing the mat core material from the outer bag and wiping the surface, and it is easy to always maintain a clean state. It is suitable as a mat for hospitals and hospitals.

However, every time the mat is soiled by incontinence or food, the mat core material is taken out of the outer bag, the outer bag is washed, and the contaminated portion of the mat core material is wiped off. It is extremely troublesome to store it in the outer bag again, and since the outer bag is made of cloth, it takes a long time to dry, and there is a problem that it cannot be used during that time.

[0005] In addition, hospital-acquired infection has recently been highlighted as a major social problem. To address this problem, it is necessary to keep the mat as clean as possible, for which it is desirable to be able to wash the mat frequently, as if washing underwear. However, as described above, the conventional method of taking out the mat core material from the outer bag, washing the outer bag, washing the mat core material, and then storing it again in the outer bag takes time and effort. It is hardly practical at all.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides a mat which can be washed easily and in a short time while being stored in an outer bag without taking out a core material for the mat from the outer bag. To provide.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and as a result of intensive studies to solve the above-mentioned problems, it has been found that a mat core material made of a polyolefin synthetic resin foam molded article is housed in a net-shaped outer bag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings showing the embodiments. In FIG. 1, a washable mat 1 of the present invention comprises a mat core 2 made of a polyolefin-based synthetic resin foam molded article. Of the outer bag 3.

The mat core 2 is made of, for example, polyethylene,
A foam molded article of a polyolefin-based synthetic resin such as polypropylene or a copolymer resin thereof is preferable because it has both an appropriate cushioning property and rigidity. An in-mold foam molded article or an extruded foam molded article made of these resins is suitably used.

The mat core material 2 may have a wavy surface or a shape having a large number of bulging portions in order to ensure air permeability and acupressure effect. May be provided with a small thumb-sized projection for the purpose of acupressure effect on the surface near the top of the head. Further, through holes can be formed in the longitudinal or oblique direction of the core material to further enhance air permeability. Furthermore, for example, it is also possible to make one surface flat and the other surface corrugated, and to use both the front and back surfaces properly.

Although the mat core 2 may be of a single type,
If necessary, a split type such as two or three may be used. The split type has an advantage that it is easy to handle and can be split and stored in a closet or closet when not in use.

The mat core 2 is preferably subjected to an antibacterial treatment or a deodorizing treatment. As the antibacterial agent and the deodorant, known ones can be used. Silicone dioxide (SiO ₂ ) and alumina (Al ₂
O ₃ ), titania-based (TiO ₂ ), zirconia-based (Zr
O _2), other such ferritic (Fe ₂ O _3), serpentine (hydrous silicate minerals magnesium) and tourmaline _{[3 {NaX 3 Al 6 (BO} 3) Si 6 O 18 (O
H ₉ F) ₄ }. Examples of the antibacterial agent include powders of gold, silver, copper, zinc and the like, ions thereof, copper compounds such as copper sulfate, cuprous sulfide, and cupric sulfide, and diphenyl ether compounds. These may be used alone or in combination of two or more.

Examples of the deodorant include those which exhibit a deodorizing effect by a desulfurizing action, such as iron sulfate and iron hydrochloride, and those which are oxidized or deoxidized, such as an oxidizing agent or a reducing agent.
Those exhibiting a deodorizing effect by a reducing action, those exhibiting a deodorizing effect by a condensation or addition reaction such as lauryl methacrylate or fumarate ester, and the like, and those by a physical action include activated carbon and zeolite ,
Silica gel and the like that exhibit an odor eliminating effect by adsorbing odors on the porous surface are used, and these are used alone or in combination of two or more. A deodorant by a chemical action and a deodorant by a physical action can be used in combination.

These antibacterial agents and deodorants are contained (kneaded) in a core material for mats, or dispersed or dissolved in a solution comprising a binder resin and a solvent to prepare a coating solution. Apply and dry on the surface of the mat core material.

It is preferable that the mat core material 2 is subjected to an antifouling treatment. Known antifouling agents can be used, but silicone compounds are preferred from the viewpoint of safety. An antifouling agent is also contained (kneaded) in the mat core material, or is coated on the surface of the mat core material. By performing the antifouling treatment, the mat core material is hardly soiled, and even if it is soiled, it can be easily removed.

The net-shaped outer bag 3 is not particularly limited as long as dust and dust adhering or accumulating on the mat core material can be removed from the net-shaped eyes of the outer bag together with various germs. If the size is too large, the aesthetic appearance is impaired. On the other hand, if the size is too small, it becomes difficult to remove dirt and dust. Therefore, the size of the net-like eyes is about 0.5 to 10 mm, preferably about 1 to 3 mm. The shape of the net-shaped eyes may be any shape such as a circle, an ellipse, a polygon, and an amorphous shape, and the arrangement of the net-shaped eyes is not particularly limited.

The net-shaped outer bag 3 is also preferably subjected to antibacterial, deodorant and antifouling treatments, similarly to the mat core material. That is, a net-like outer bag made of antibacterial fiber, deodorant fiber, or antifouling fiber is used, or antibacterial, deodorant, or antifouling treatment is applied to the net-like outer bag later as secondary processing.

The washable mat of the present invention is used together with a sheet if necessary, and the sheet preferably has a structure that can be easily removed. In the case of a structure that cannot be easily removed, such as a zippered bag-like sheet, it is troublesome to remove the sheet during washing, which reduces the purpose of the washable mat of the present invention.

As a sheet that can be easily removed, a flat sheet is hung on a washable mat, and the surroundings are laid on the back of the mat. Also, as shown in FIG. 2, concave accommodation portions 5a, 5a are provided at both ends in the longitudinal direction.
As shown in FIG. 3, it is preferable to use the sheets 4 provided with the b. and to use the end portions of the mat pieces 6a and 6c at both ends in the concave storage portions 5a and 5b, respectively. Sheets 4 having such a structure can be easily relaxed by removing middle mat piece 6b, for example, so that mat pieces 6a, 6b, 6 can be easily formed.
c can be removed. Sheets also use sheets made of antibacterial fibers, deodorant fibers, and antifouling fibers, as in the case of the net-shaped outer bag, or antibacterial,
It is preferable to perform a deodorizing treatment or an antifouling treatment.

The method for washing the washable mat of the present invention is not particularly limited, but a method of discharging water, preferably spraying water (low to high pressure water) with increased pressure, onto a mat or a piece of mat (hereinafter referred to as a mat). And a method in which a mat is placed in a washing tub and the mat or water is moved to perform washing in the same manner as in a normal washing machine. Needless to say, a detergent, a disinfectant or an antibacterial agent may be added to the water, or a method of physically removing stains such as a brush may be used in combination. Of course, hot water may be used instead of water. After washing, it may be dried in the air or in a drying room. In this case, when dried in the sun, solar energy is accumulated in the foam cells of the core material for the mat, and it is warm for a long time, and is particularly suitable in winter and the like. The washable mat of the present invention has a mat core material that is non-hygroscopic and excellent in water repellency, and since the outer bag is also in the form of a net, it dries in a very short time, for example, when a sick person is in a medical examination or walking. Can be washed. The washed washable mat is subjected to antibacterial, deodorant or antifouling treatment as required.

[0022]

As described above, the washable mat of the present invention can be washed as it is without taking out the core material for the mat from the inside of the outer bag, so that it is not troublesome and it is as if washing underwear. Easy to wash. Moreover, since the mat dries in a short time, the time during which the mat cannot be used due to washing can be extremely short. In the future, with the rapid transition to an aging society, the number of bedridden elderly and sick people is expected to increase. Very important, the present invention greatly contributes to such a demand.
