Double=walled hose with dye between walls, especially for showers

摘要

The hose is made from inner (2) and outer (3) hoses, and the region between them is dyed. The outer side of the inner hose and/or the inner side of the outer hose is dyed directly. At least one dye (4), especially an undercoat, may cover the whole surface. Two layers may be used, and the outer one may be transparent and/or may not completely cover an inner coloured layer. The outer surface of the inner hose may be smooth, and the outer hose may lie against it over its entire surface.
