BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coaster laid under a cup or the like when a cup or the like containing a beverage is placed on a table or a desk.

[0002]

2. Description of the Related Art Problems to be solved by conventional techniques and ideas In a general household or a restaurant, when placing a cup on a table or a desk, a rug such as a coaster is laid under the cup. By placing the cup with the drink poured on the coaster, it is possible to prevent the table and desk from being damaged by the impact of placing the cup, and water droplets adhering around the cup etc. will cause the table and desk to drop. Can be prevented from getting wet. Coasters also have the effect of enhancing the aesthetic appearance and enhancing the taste of beverages by selecting the material and color of the coaster in consideration of the shape and color of the cup and combining it with the cup. Conventionally, coasters made of natural materials such as wooden, bamboo, and cork, and those made of plastic, silicone resin, and the like are used. Paper coasters are widely used in restaurants and coffee shops. However, coasters made of natural materials such as wood and bamboo have a problem in that when they are used, water seeps in and the surface is discolored and mold is generated. Coasters made of plastic or resin have high water resistance, but do not absorb moisture, so they are slippery, such as cups, and water droplets generated around cups accumulate on the coaster surface. When raising the cup, there was a problem that water drops dripped from the bottom of the cup and wet the surrounding area.

[0003] Therefore, in coffee shops and restaurants, paper coasters having high water absorbency are widely used, but paper coasters cannot be washed and become disposable, and are inorganic and inexpensive. I can't deny the feeling. In addition, when used for a long period of time, there is a problem that the sheet is excessively moist and is deformed or ruptured. There are also coasters made of cloth that can be washed.However, since two pieces of cloth are overlapped and sewn around the perimeter, or one piece of cloth is folded and used as a coaster, water drops that condense on the outer wall of the cup and fall off There was a problem that the water penetrated to the back of the fabric and wet the table and desk. In the above-mentioned coaster, the water that has infiltrated or accumulated on the surface of the coaster closely adheres to the bottom of the cup in a film-like manner, adsorbs both, and when the cup is lifted, the coaster also rises. There was also the problem of being lifted together.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] The present invention is intended to solve the above-mentioned problems, and has high water absorption and can be washed, and furthermore, the moisture penetrates to the back surface to allow a table or a desk to be used. It is intended to provide a coaster that does not wet and does not stick to the bottom of the cup. That is, the present invention is a coaster having the following configuration. (1) A coaster made of a composite material consisting of a waterproof plastic thin film bonded and laminated on the back of a water-absorbing fabric. (2) A coaster made of a composite material made by joining and laminating a waterproof plastic thin film made of vinyl chloride on the back of a water-absorbent cloth made of towel cloth. (3) The above (1) or (1), wherein the thickness of the water-absorbent fabric is 0.5 to 8.0 mm, and the thickness of the waterproof plastic thin film is 0.05 to 0.5 mm. 2) The coaster according to any one of the above. (4) The coaster according to any one of (1) to (3), wherein the surface of the water-absorbent fabric is cut and piled. (5) The coaster according to any one of (1) to (4), wherein a light-emitting material is contained in a water-absorbing fabric, a waterproof plastic thin film, or an adhesive between the two.

A peripheral processing section 3 which has been subjected to a peripheral processing is formed at an end portion 10, that is, at a peripheral portion of the coaster 1. A pile thread 6 is formed on the cloth surface of the towel cloth 2 constituting the composite material 10 to reduce the impact when the cup is placed on the coaster 1 during use, and to absorb water and moisture. Improves gender. In FIG. 4, the coaster 1 is composed of a composite material 10 ′ in which a plastic thin film 5 made of vinyl chloride and a towel cloth 2 are joined and laminated via a vinyl chloride resin adhesive 7. At the end of the composite material 10 ′, that is, at the periphery of the coaster 1, there is formed a periphery processing section 3 which has been subjected to the periphery processing. A cut pile thread 6 is formed on the cloth surface of the towel cloth 2 constituting the composite material 10 ', which enhances the stability when the cup is placed on the coaster 1 during use and improves the water absorption. It has improved properties and hygroscopicity.

The pile yarn 6 on the cloth surface of the towel cloth 2 on the surface of the coaster 1 can be cut on the entire surface or cut only on a part thereof. For example, although not shown, the composite material 10 is formed in a square shape, and a pile cut having a circular shape is formed at the center position of the towel cloth 2 on the surface of the composite material 10 (at the place where the cup is to be placed) on the order of the size of the bottom of the cup. It is also possible to adopt a configuration in which a loop pile (pile yarn not subjected to a pile cut process) is formed after the treatment is performed. With this configuration, the cup is placed on the cut pile yarn 6 ′ on which the pile cutting process has been performed, so that the stability at the time of placing is improved and the periphery of the pile pile yarn 6 ′. Thus, the coaster 1 can surely absorb and absorb water droplets and the like that drip from around the cup. In addition, by cutting a part of the pile yarn 6 on the cloth surface of the towel cloth 2 on the surface of the coaster 1, a pattern or pattern can be formed, so that the overall design of the coaster 1 can be improved. .

Here, an example of a method of manufacturing the composite material 10 constituting the coaster 1 of the present invention will be described with reference to FIG. First, a vinyl chloride resin-based adhesive solution 70 is applied to the plastic thin film 5 made of vinyl chloride, and then heated and semi-dried by the heater 8. The heater 8 generally uses hot air as a heat source, but may use a far-infrared heater, a dryer drum, or the like. Then, the plastic thin film 5 made of vinyl chloride and the towel cloth 2, which have been subjected to the heat treatment by the heater 8, are pressed and contacted by a roller, and are completely joined and laminated by a heating drum 9 to form the composite material 10. Complete. Here, a vinyl chloride resin-based adhesive 7 is used as the adhesive. However, an adhesive that can securely join and laminate the plastic thin film 5 made of vinyl chloride and the towel cloth 2 and has excellent water resistance. Any adhesive may be used. For example, a synthetic adhesive such as a vinyl acetate-based adhesive may be used, but a vinyl chloride resin plastisol-based adhesive which is particularly rich in water resistance, excellent in adhesiveness and rich in elasticity is preferred.
