Abstract
A cap used for refilling ink cartridge for printer includes a body which is forcibly inserted into an ink supply hole of the printer. A cylindrical ink receiving space is depressed into the body. A thin-film part, through which a nozzle of the printer pierces, is defined by the bottom surface of the ink receiving space. The diameter of the thin-film part is substantially the same as that of the nozzle of the printer. A plurality of leakage-preventing protrusions are integrally formed around the outer periphery of the body. Each protrusion includes an outward-slanted portion which is formed downward from the outer periphery of the body while being slanted outward, and a horizontal portion which is extended horizontally to the outer periphery of the body from the lower end of the outward-slanted portion.
