Description

The present invention relates to a urinal.

Conventionally, urinals made of pottery have been used. This is preferable for mass production, and has been used for many years because its surface is relatively smooth, bacterial growth is suppressed, and it is hygienic.

Such urinals are used not only for private residences but also in public facilities such as parks. In addition, many applications relating to such urinals have been made, and for example, the urinals described in JP-A-07-101690 are also disclosed as those made of pottery.

However, in recent years, some people have committed illegal acts such as destroying urinals installed in public facilities such as parks. That is, since the urinal is made of pottery, it is smashed and destroyed by something like a crowbar. In such a case, it costs a lot of money to repair the destroyed urinal, and the time loss until the repair is also great.

It is possible to seek compensation from such a destroyed person, but it is not easy because he has escaped. In addition, urinals that are not easily destroyed are required because they cannot be used by others during the restoration. In addition, since it is installed in public facilities, it is required to reduce troubles related to drainage.
