Patent

CA 2346272

A pen with a novel ink supplying bodying device is disclosed. The pen body may supply ink steadily and has a simple structure. A large amount of ink can be stored therein and the pen has a compensating function according to the variation of pressure. A plurality of spacing walls are used to space a ink storage chamber (2) into a plurality of small chambers (2a, 2b, 2c, and 2d). Linking holes are formed in these spacing walls, or an ink storage body penetrates through these spacing walls (14). Capillary forces in the linking holes retain the sealing of the ink film. When pressures in the small chambers are changed due to consumption of ink or variation of temperature, then ink flows out of the small chamber to the pen body (5) so as to reduce the ink output to the storage cavity (10) and the capacity of the ink storage chamber is increased.
