Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tabletop rug used for protecting the surface of a table such as a dining table or improving the aesthetics of the table.

[0002]

[Prior art]

 To prevent scratches and stains on the table surface due to tableware, etc., or to improve the aesthetics of the table or prevent damage to the glass, use tablecloths, placemats, etc. made of natural fibers such as cotton, synthetic fibers or synthetic resins. Bedding is used. These rugs are typically used on a table with a smooth surface, so slippage of the rug can cause the glass to fall over and spill drinks, or tableware on the rug to fall off the table and become damaged. I was afraid to do it. For this reason, it has been proposed to form a non-slip layer that uses the frictional force of polyurethane or the like on the back surface of the rug to prevent the rug from slipping.

[0003]

[Problems to be solved by the device]

 However, in the case of the rug with the anti-slip layer using the frictional force as described above, the frictional force of the anti-slip layer suppresses the horizontal displacement of the rug, but the restraining force is insufficient. Met. Further, repeated washing may cause the polyurethane to be detached from the litter, or the anti-slip effect may be reduced.

The present invention has been made in view of such circumstances, and by forming a non-slip layer having a vacuum suction force or an adhesive force on one surface of a sheet, the force of suppressing deviation of a tabletop rug is improved. The purpose is to provide a tabletop rug.

[0005]

[Means for Solving the Problems]

 A desk layer according to a first invention is characterized in that a non-slip layer made of synthetic resin and having a vacuum suction force is provided on one surface of a sheet.

[0006] A tabletop wrapping cloth according to a second aspect of the invention is characterized in that a non-slip layer made of synthetic resin and having an adhesive force is provided on one surface of a sheet.

[0007]

[Action]

 In the tabletop lining according to the first invention, the anti-slip layer formed on the back surface has good adhesiveness due to the vacuum suction force, so that the slippage can be achieved regardless of the material composition of the surface of the table such as metal and resin. The stop layer is brought into contact with the surface of the table and is lightly pressed to easily adhere to it, preventing slippage and floating. On the other hand, it has good peelability and can be easily removed. In addition, the anti-slip layer has excellent wash resistance, and if the surface of the tabletop is soiled, remove it by washing and use it again. Furthermore, the anti-slip layer acts as a cushioning material to absorb the impact of the tableware and glass on the table surface.

In the tabletop ware of the second invention, since the adhesive layer formed on the back surface has good adhesion due to the adhesive force, in addition to the first invention, there is a case where the surface of the table is not smooth. Even so, it is closely adhered to it to prevent the slippage and floating of the litter.

[0009]

【Example】

 Hereinafter, the present invention will be specifically described with reference to the drawings showing an embodiment thereof. FIG. 1 is a schematic perspective view of a desk mat according to the present invention applied to a luncheon mat, with the thickness direction being emphasized. A non-slip layer 2 having a vacuum suction force is formed on the back surface of a woven or non-woven sheet 1 by coating a mixture having the composition described below, for example, on the entire surface or in a plurality of strips. The place mat 3 is pressed onto the table surface by bringing the non-slip layer 2 into contact with the table surface (not shown) and lightly pressing it.

The composition of the anti-slip layer 2 is as shown in Table 1. Specifically, the synthetic resin (emulsion type) is a urethane type product “DICFOAM F-520” and the foaming agent is “F-1”. 4% concentration of "CMC" as surfactant, "VONCOAT 3750" as auxiliary agent (1), "CR-5L" as auxiliary agent (2), "VONDIC NBA-1" as auxiliary agent (3), catalyst "CATA LYST PA-20" was used as. "CMC" is manufactured by Daiichi Kogyo Seiyaku Co., Ltd., and other products are manufactured by Dainippon Ink and Chemicals, Inc.

[0011]

[Table 1]

The adhesion mechanism of the anti-slip layer 2 made of such a material to the table is the vacuum adsorption force due to the large number of pores formed here. In other words, if this is suppressed a little, the air in the pores will be exhausted and a depressurized state will be created, whereby it will adhere to the table surface. As a result, the occurrence of displacement of the tabletop lining and the occurrence of floating can be prevented.

When the anti-slip layer 2 is formed by coating on the sheet 1, first, the compositions shown in Table 1 are mixed and foamed by a mixer. Next, the foamed composition is applied to one surface of the sheet 1 by a coating device. Then, this is placed in a dryer and dried at 120 to 160 ° C. for 5 minutes.

At this time, the results of the physical property test of the anti-slip layer 2 when the anti-slip layer 2 was applied by changing the expansion ratio and the coating thickness are shown in Table 2. From Table 2, it can be seen that when the expansion ratio is small, the releasability is good, when the expansion ratio is large, the adhesion is good, and when the coating thickness is increased, both are improved.

The expansion ratio and the coating thickness may be determined from the results shown in Table 2 in consideration of the required balance of performance.

[0016]

[Table 2]

The method of measuring the results shown in Table 2 is specifically as follows. Delamination strength: Sample preparation Apply adhesive (F-520 thickening liquid) to cotton cloth, stick to foam surface, heat-treat and cut into 2 cm width. Measure foam breaking strength by autograph. Cellophane tape peeling strength: Stick cellophane tape (1.8 mm) firmly on the foam surface by hand, peel off instantly in the right angle direction, and check for damage. ○: No abnormality ×: Damage Surface friction strength: Rubbing the foam surface with a Gakushin type friction tester (Flat 500g) and reading the number of times until damage. Adhesion: A 2 cm wide foam sheet is pressure-bonded to a glass plate, and after 1 day, the 90 ° peel strength is measured. Even when the washing was repeated 20 times, there was no change in the adhesion of the anti-slip layer 2.

Next, Table 3 shows other examples of the composition of the anti-slip layer 2. The products used as the composition in Table 3 are the same as those in Table 1.

[0019]

[Table 3]

When the anti-slip layer 2 made of the composition shown in Table 3 is applied to the sheet 1, the composition shown in Table 3 is first mixed and foamed 3.3 times with a mixer. Next, the foamed composition is applied to one surface of the sheet 1 by a coating device. Then, this is placed in a dryer and dried at 120 ° C for 5 minutes and 140 ° C for 2 minutes. In this case as well, as in the case of the above-described embodiment, good adhesion to the table due to the vacuum suction force was obtained.

The composition of the non-slip layer 2 in the second invention is Mitsui DuPont's EV-40LX as ethylene vinyl acetate (EVA) and Exxon's XS-5508 as ethylene methyl acrylate (EMA), and EVA and EMA. And the weight ratio thereof was 7: 3. Then, such a mixture was applied to a sheet 1 with a film thickness of 200 μm by an extruder having a diameter of 90 mm to make a tabletop prototype. The non-slip layer 2 made of such a material has an adhesive force on the surface and adheres to the table by this adhesive force.

The physical properties of this prototype tabletop rug were measured at four points: physical property change with temperature change, washing resistance, heat resistance, and change in adhesive strength with time. The size of the prototype is 25 mm wide x 10 cm, and when laying this prototype on a table, we decided to load it back and forth twice with a 1 kg roll. Hereinafter, each physical property will be described.

Changes in Physical Properties Due to Temperature Changes The temperature of a prototype tabletop-equipped tabletop was changed to 0 to 40 ° C., and the physical properties of the tabletop bedclothes were measured. The measurement results are shown in Table 4 below. The test method was to place the prototype on a table, apply a load by reciprocating a 1 kg roll twice, and leave it at each temperature for 30 minutes, and then measure the adhesive force.

[0024]

[Table 4]

In a temperature range of 0 to 40 ° C., which is a daily use temperature range, there is no resin adhesion and good adhesiveness is exhibited.

Washing resistance The washing resistance of the prototype was also measured. The measurement results are shown in Tables 5 and 6 below. The measurement method is as follows: Put 30 liters of water and 25 g of neutral detergent in a home washing machine, wash for 10 minutes, wash for 10 minutes with water, dehydrate, dry with hot air at 40 ° C for 15 minutes, then return to room temperature (20 ° C). The procedure of sticking to and measuring the adhesive strength was repeated.

[0027]

[Table 5]

[0028]

[Table 6]

It can be seen that the adhesiveness hardly deteriorates even after repeated washing.

Heat resistance After the prototype was attached to the table, the temperature of the table was set to 40 ° C., the sample was left standing for 40 hours with a load of 30 kg, and then the sample was peeled off. As a result, the resin was peeled off without adhering to the table, so it can be said that the heat resistance at about 40 ° C is good.

Change in Adhesive Strength with Time Aging After the prototype was attached to a table, deterioration of adhesive strength and discoloration were observed. The observation results are shown in Table 7 below.

[0032]

[Table 7]

The adhesive strength does not change even after one month has passed, and no discoloration is observed, so that the physical properties are not deteriorated even when used for a long period of time.

FIG. 2 is a perspective view showing how the luncheon mat shown in FIG. 1 is used. The back surface of the lunch mat 3 is coated with a non-slip layer having a vacuum suction force or an adhesive force and is closely attached to the table 10. Since such a place mat 3 can be easily attached and detached, it can be easily placed at a desired position on the table 10. After being placed, the place mat is closely attached to the place mat so that it may come into contact with human hands or dishes. Can't come off. Further, even if a tableware or a glass having water droplets or the like on its back surface is lifted from the luncheon mat 3, the occurrence of floating of the bed is prevented. Further, the anti-slip layer of the luncheon mat 3 serves as a cushioning material to absorb the impact between the tableware or glass and the table 10. If the surface is further soiled, it can be removed by washing and used again. The tabletop lining according to the present invention can also be used as the coaster 4, and has the same effect as the lunch mat 3.

FIG. 3 is a perspective view showing another usage mode of the tabletop rug according to the present invention, which is used as a table cloth. A non-slip layer having a vacuum suction force or an adhesive force is applied to the back surface of the table cloth 5 to form a table, regardless of the material composition of the surface of the table 10, such as resin, varnished wood, glass, etc. Since the cloth 5 is easily crimped by covering the table 10 with light pressure on the surface thereof, the table cloth 5 is prevented from being displaced even if a child's mischief or inadvertent pulling force acts.

It should be noted that the surface of the table cloth 5 is water-repellent processed, and dirt is unlikely to adhere to the surface of the table cloth 5. On the other hand, since it is easy to put on and take off and has high resistance to washing, if dirt adheres to it, remove the table cloth 5 from the table 10, remove the dirt by washing, and crimp it to the table 10 again. Let When a non-slip layer is applied to the back surface of a sheet of cotton or the like to form the table cloth 5, wrinkles do not occur on the sheet because the anti-slip layer made of synthetic resin does not cause wrinkles due to washing and drying. It is prevented and ironing is unnecessary.

FIG. 4 is a perspective view showing still another mode of use of the tabletop rug according to the present invention, which is used as an insole of a cupboard. As mentioned above, the non-slip layer is applied and formed on the back surface of the insoles 6, 6, ... In such an insole 6,6, ..., it is difficult for the person's finger or tableware to come into contact with the tableware when the tableware is taken in and out, so that the tableware is smoothly taken in and out, and the tableware comes into contact with the tableware. This will prevent accidents such as dropping dishes.

Since the tabletop lining according to the present invention can be easily cut, it can be formed into a shape according to the purpose of use or taste. Needless to say, the tabletop rug according to the present invention can be used not only as a luncheon mat and coaster but also as various tabletop rugs such as a pot bed and a vase bed.

[0039]

[Effect of device]

 As described above in detail, the tabletop garment according to the present invention has an anti-slip layer having a vacuum suction force or an adhesive force on one surface thereof, and thus has an excellent effect of preventing slippage and floating. Further, since the anti-slip layer has a shock absorbing function, it has a high effect of protecting the table surface and preventing damage to dishes or glasses. Furthermore, the present invention has excellent effects such as excellent wash resistance, and even if the surface of the tabletop is dirty, it can be removed by washing and can be used repeatedly, resulting in high economic efficiency.
