[Problems to be solved by the invention]
This eye wash is simple in structure, light in weight and easy to handle, but because of its structure, it is difficult to form by a general molding method using a general synthetic resin such as polypropylene or polyethylene. It can be formed by injection molding using a flexible material such as rubber. However, when soft materials such as rubber are used for the eyewash, some of them may have an adverse effect on the eyeball and skin that are in direct or indirect contact, so there are restrictions on the flexible materials that can be used. Is generally expensive, such as silicon rubber or butyl rubber.
