Inverted Cone Umbrella

Inverted cone filtration (ICF) is a process used to remove particulate and dissolved contaminants from a designated fluid such as water. In a typical design, fluid enters the narrow top end of the filter falling onto a chamber where pressure head is built to force the fluid across woven filter media.The purpose of the reverse umbrella is to keep the wet side of the umbrella away from the user on rainy days. Some people argue that the Taiwanese inventor Li Sheng Chun, the owner of Taiwanese patent I254619, was the originator of the reverse umbrella, although he did not put his patent into commercial practice.Don't let the rain make its way into your house by dripping off your umbrella; trap it inside with the upside-down design. The unique technology that went into the structure of this umbrella traps the water inside the durable canopy fabric and prevents drips, spills, and messes.
