[origin: EP0894536A2] At least one surface area of the spray disc is curved outwards and on exceeding a certain press-in force (E), the springs suddenly round with the curvature inwards into a space behind. On relaxing the force the surface area springs back again by itself into the starting position. The at least one surface area can be pressed in by a finger where the surface of the disc is larger than the finger tip. The spray disc can have a material weakness along a closed line and is formed by a thinner material area.
