Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray with a liquid absorbing sheet which can be easily replaced and used hygienically.

[0002]

2. Description of the Related Art Conventionally, toilet mats to be laid on the floor of a toilet and kitchen mats to be laid around a kitchen sink have been required to have an effect of absorbing liquid when the liquid scatters around. It is often used for its effects and hygiene. As this type of mat, a pile fabric containing water-absorbing fibers is generally distributed. Certainly, in home use, the number of users is limited, and it is relatively easy to deal with hygiene, and it is unlikely that regular washing is troublesome. However, if there is a lot of sewage adherence such as a public toilet or a restaurant kitchen and frequent sprinkling of water on the floor for cleaning or sanitary beautification, replacement work such as washing and drying of the mat becomes complicated, There are also inconveniences, such as a reduction in the number of replacements, which naturally causes hygiene problems.

[0003] Therefore, disposable inexpensive mats have also been proposed, for example, a toilet mat made of a water-containing material (Japanese Utility Model Laid-Open No. 4-136199) and a toilet mat made of a moisture-absorbing or water-absorbing sheet. (JP-A-7-213458), a toilet mat having a water-absorbing material layer for absorbing urine (JP-A-8-164,094), and a liquid-absorbing sheet containing a sheet that easily absorbs liquid (JP-A-9-290489). Are disclosed.
Specifically, as a material for achieving water absorption, a polymer absorbent, hydrophilic resin fiber, pulp fiber, natural fiber, papers, nonwoven fabric, and the like are exemplified, and a back surface is used to prevent liquid from passing to the back surface. It is also disclosed that a waterproof layer is disposed on the vehicle.

However, in principle, these water-absorbing sheets are used alone, and in order to prevent misalignment due to tread pressure as a rug and to fix the laying, separate members such as a double-sided adhesive tape and a sheet fastener are used. Therefore, in disposable applications, it can be said that the target member other than the liquid absorbing function is a factor that increases the cost and is difficult to spread.

[0005]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention makes it possible to easily lay and fix a disposable liquid absorbing sheet at a predetermined position, and keep the floor of a toilet or kitchen sanitary. For this purpose, a dedicated tray and a liquid absorbing sheet are used in combination.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a waterproof plate-like member which is divided by the guide with respect to a tray formed by erecting a guide on the periphery of a waterproof plate-like member having an appropriate size and shape. A tray with a liquid absorbing sheet, wherein a liquid absorbing sheet is laid on the surface of the body.

In a more preferred form, the liquid absorbing sheet used in this tray is laid on the tray in a multiplexed state, and the liquid absorbing sheet is a laminate of a synthetic resin film of a back layer and a water absorbing material of a surface layer. It is characterized by having.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The tray used in the present invention has a structure in which a plate-like body having waterproofness is used as a base and the periphery of the base is surrounded by a guide. The material is not limited to a water-repellent material such as a synthetic resin or a rubber material, but may be a water-absorbing wooden or paper-like material laminated with a waterproof coating such as latex. However, a synthetic resin or a rubber material is preferable from the viewpoint of production, for example, because it has a container-like structure and can be integrally molded by a mold or the like.

The tray is installed directly on the floor, and a liquid absorbing sheet is laid in an area surrounded by a guide in the tray, and is used for positioning and fixing the liquid absorbing sheet. Therefore, it is sufficient that the purpose of preventing displacement of the liquid absorbing sheet can be achieved in the guide standing on the peripheral edge, and the height of the guide may be designed in consideration of the thickness of the liquid absorbing sheet and the number of laminated sheets, and the tray sectional shape is box-shaped. It may be a container or a dish-like container. The shape of the tray does not need to be limited, and in addition to a general rectangular shape, for example, when corresponding to a toilet mat, a cutout along the shape and step position of the toilet bowl can be formed.

[0010] Regarding the loading of the liquid absorbing sheet into the tray, it is possible to always use one sheet at a time and replace it periodically or according to the condition of dirt or water absorption. From the viewpoint of stocking, it is preferable to lay a plurality of liquid absorbing sheets on a tray as one unit. In this case, the displacement of the liquid absorbing sheet can be prevented due to the existence of the guide of the tray simply by stacking a plurality of sheets. However, if practicality is sought, it is preferable that the integrated sheet be easily peelable and partially integrated. Can be dealt with by applying a low-adhesive material to the substrate.

The back surface of the tray may be subjected to anti-slip processing as required. Specific examples of the anti-slip processing include applying an adhesive, attaching an elastomer film or foam sheet having a high frictional resistance, forming irregularities by embossing, and arranging suction cups.

Next, the liquid absorbing sheet to be loaded on such a tray will be described. The liquid absorbing sheet is expected to quickly absorb and hold the liquid scattered on the surface thereof, and therefore includes at least a liquid absorbing material in its configuration.

[0013] The liquid-absorbing material is made of vegetable fiber such as cotton or hemp, animal fiber such as wool, rayon fiber, pulp fiber, or synthetic fiber subjected to hydrophilic treatment. The formed one is easy to handle. It is not necessary that these fibers are all fibers, and other synthetic fibers may be mixed in consideration of the required liquid absorbency. For example, in order to stabilize the shape of the sheet, a heat-fusible fiber having a low melting point and adhesiveness may be mixed and heat-treated.

It is preferable that the liquid absorbing sheet is mixed with a water absorbing polymer for the purpose of maintaining the liquid absorbing state. Examples of the water-absorbing polymer include, in addition to natural resins such as starch, polymers crosslinked with polyacrylic acid, polystyrenesulfonic acid, maleic anhydride, carboxymethylcellulose, cellulose ether, polyvinyl alcohol, polyvinylpyridine, polyethylene oxide, and the like. Is mentioned. These water-absorbent polymers can be sandwiched between nonwoven fabrics, blended with water-absorbent polymers and melt-molded as fibrous or sheet-like foams, or water-absorbent polymer powders can be mixed with other fibrous materials. It can be used in various forms, such as by attaching it to an adhesive.

Various functions can be imparted to the liquid absorbing sheet by additives and the like. For example, a deodorizing effect can be obtained by a solid acid such as activated clay, a neutral substance such as zinc oxide, a solid alkali such as calcium carbonate or aluminum hydroxide, a photocatalyst such as titanium oxide, activated carbon, or the like, or N, N'- Diethyl metatoluamide, 2-hydroxyethyl octyl sulfide, 2,2-dimethyl-3- (2
-Methyl-1-propenyl) -cyclopropane-1-carboxylate, 2,2-dibromo-3-nitrilepropionamide, etc., can provide antibacterial and antifungal effects, and may be appropriately added.

Although such a liquid absorbing sheet is a completely disposable member, it is easy to handle and has a preferable structure that can be used more hygienically. Is a laminate made of a liquid absorbing material. In the case of a multi-layered configuration described above as a preferred method of loading the liquid absorbing sheet, if the liquid absorbing material alone overflows the water absorption, it naturally absorbs water to the sheet located in the lower layer, which is not economical. Therefore, this is effectively blocked by a waterproof synthetic resin film as a liquid impermeable layer. As synthetic resin film, polypropylene,
High-density polyethylene, ethylene-vinyl acetate copolymer,
It is molded from a general-purpose thermoplastic resin such as an ethylene-acrylic acid copolymer, polyethylene terephthalate, nylon-6, nylon-66, polystyrene, or polyvinyl chloride.

The water-absorbing material and the synthetic resin film may be laminated by bonding the film to the water-absorbing material directly by bonding with an adhesive or fusing powder, pressure bonding with a heating roll or embossing roll, or extrusion lamination. Become

Further, based on this laminated structure, a liquid-permeable sheet such as a perforated film or a nonwoven fabric can be laminated as a surface material on the outermost layer.

FIG. 4 shows an example of a laminated structure of the liquid absorbing sheet 3, and a specific member configuration will be described below. As the liquid-permeable surface material 31, a long-fiber nonwoven fabric having a basis weight of 30 g / m ² obtained by a spun bond method and containing a low-melting heat-fusible fiber was prepared. As a liquid-absorbing material 32 for absorbing and retaining a liquid, a fibrous nonwoven fabric having a basis weight of 60 g / m ² in which hydrophilic pulp fibers and acrylic acid-based water-absorbing fibers were mixed was prepared. As the liquid impermeable layer 33, a waterproof film having a basis weight of 20 g / m ² formed from a polyethylene resin was prepared. In a state where these members were superimposed in this order, a peelable pressure-sensitive adhesive layer 34 was applied to the lowermost film surface of the obtained laminate which was pressed through a heated embossing roll, and this embodiment was performed. The liquid absorbing sheet 3 of the example was used.

Since the liquid absorbing sheet of this embodiment has a peelable pressure-sensitive adhesive layer, it is easy to stack a plurality of sheets and integrally handle them, and they can be laid in a tray. A hygienic state can be maintained by sequentially peeling and using the sheet that has been in the liquid absorbing state for an appropriate period or periodically.

[0023]

According to the present invention, a dedicated tray and a liquid absorbing sheet are used in combination on a floor surface such as a toilet or a kitchen where liquid may splash. Therefore, it is possible to easily lay or fix the disposable liquid absorbing sheet at a predetermined position, to effectively prevent positional displacement due to tread pressure as a rug, to be easy to handle, and to be able to continue to be used hygienically. It is effective as a thing.
