Description

[Detailed explanation of the invention] <Industrial field of application> The invention is a material with excellent water absorption that can be placed under a pot, etc.
The present invention also relates to a water absorbing coaster that does not undergo swelling changes due to water absorption and has good reusability.

<Prior art> Coasters absorb water droplets that condense on the outer wall of a container that normally holds cold beverages, etc. and fall to the bottom of the container, and when the container is lifted, the water droplets fall onto a table or clothes. It was intended to prevent

<Problem that the invention aims to solve> For this reason, coasters are required to be made of materials with excellent water absorption, and currently many coasters are made of paper or synthetic resin such as vinyl. Can be seen. However, although the former has excellent water absorbency, it has the disadvantage of repeated use, such as when it gets too wet, it deforms when dried and cannot be reused. Furthermore, although the latter has durability, it has the disadvantage of poor water absorption.

<Means for solving the problem> A plurality of holes are provided in the upper surface of the coaster body, which is a hollow dish-shaped body made of heat-resistant material, and the inside of the coaster body has excellent water absorption and water retention properties, and It does not swell due to water absorption, and contains vermiculite that is resistant to heat. (The vermiculite referred to here is the vermiculite obtained by heating and expanding raw vermiculite.) <Function> The coaster of the present invention having the above structure is placed under a cup containing a cold drink, etc. If it is placed on the coaster, even if water droplets condensed on the outer wall of the coaster flow down to the bottom of the coaster, the water droplets will be absorbed by the vermiculite built into the coaster through the plurality of holes provided on the top surface of the coaster. It ends up. Therefore, even if you lift the cup, water droplets will not fall on the table or clothes, allowing you to enjoy your coffee in comfort.
Moreover, when reusing this coaster, the coaster can be returned to its original state by heating the coaster to evaporate the moisture inside.

<Example> Hereinafter, an example of the coaster of the present invention will be described based on the drawings. Figure 1 is a plan view of the embodiment, Figure 2 is a plan view of the embodiment.
The figure is a substantially central vertical cross-sectional view of the embodiment. The top surface 2 of the coaster body A, which is a hollow dish-shaped body made of metal, is provided with a groove 4 along its outer edge, and the top surface 2 has a plurality of holes communicating with the inside and outside. 1...1 is provided. As shown in FIG. 2, granular vermiculite 3...3 is incorporated as a base material inside the hollow coaster body A. The coaster body A consists of an upper member A' and a lower member.
A'' is fitted, and vermiculite 3...3 is the lower member above.
The can is sealed by wrapping the outer edge of A'' around the outer edge of the upper member A'.

If the coaster body A of the embodiment having the above configuration is placed under a cup (not shown) containing a cold drink, etc., even if water droplets condensed on the outer wall of the cup flow down to the bottom of the cup, the coaster body A The water droplets are absorbed by the vermiculite 3...3 built into the coaster body A through the plurality of holes 1...1 provided in the upper surface portion 2. In addition, if a large amount of liquid spills onto the coaster body A at once, such as when a drink or the like in the cup is spilled, the vermiculites 3... A groove 4 surrounding the table prevents the liquid from flowing into the table.

Therefore, by using the coaster according to the embodiment of the present invention, even if the coaster is lifted, water droplets will not fall on the table or clothes, allowing the user to comfortably enjoy coffee.

In addition, the vermiculite 3...3 built into this coaster body A not only has excellent water absorption, but also has strong water retention properties and can retain a considerable amount of water droplets, so the coaster of the example can be used for a long time. It can withstand the use of time. Furthermore, vermiculite 3...3 does not undergo swelling changes due to water absorption or expansion due to heating, so it can be packed into the coaster body A without any gaps, thereby giving the coaster body A maximum water absorption power. Provides water retention capacity.

When reusing the coaster of the example used as described above, it may be air-dried, but the coaster of the example has a coaster body A made of metal and vermiculite that does not cause thermal expansion as described above. Since it is composed of vermiculite 3...3, if it is heated in an oven or the like, the moisture in the vermiculite 3...3 can be quickly evaporated, and it can be quickly reused.

In this embodiment, the coaster body A is made of metal, but it may also be made of heat-resistant glass, ceramic, or the like, and can be dried in a microwave oven. Further, its shape and size can be changed as appropriate. For example, it can be used to line ice buckets and beer bottles used when drinking, etc.
Its scope is wide. The holes 1...1 may also be provided not only on the top surface 2 of the coaster body A, but also on the bottom surface, or on the side surface inside the groove 4. Furthermore, the shape of hole 1...1 is also appropriate, but hole 1...
...If you string them together to make a slit shape, or line them up in order to create a pattern, they can be made into beautiful accessories.

<Effects of the invention> As described above, the coaster of this invention has excellent water absorption and water retention capacity, so it can be used for a long time, and there is no swelling change due to water absorption or expansion due to heating. It has excellent durability and can be dried by heating, so
It has an excellent effect that conventional products do not have, such as being able to be reused quickly.
