<P>PROBLEM TO BE SOLVED: To provide an ink pen structure extended in service life by efficiently protecting the pen core of an ink pen containing one sealed component and preventing problems caused by missing of a cap to reduce unexpected consumption of the ink. <P>SOLUTION: In the ink pen structure including one pen body, one main body, one moving component, one sealed component and one elastic component, the sealed component includes one hollow part, one first opening joint part and one second opening joint part, in which the first opening joint part and the second opening joint part are located at both ends of the corresponding hollow part, the hollow part is used for accommodating the pen core of the ink pen, and the first opening joint part is used to firmly and closely fit the pen core there-into. The opening of the second opening joint part is closed to put the hollow part into a sealed state, causing the pen core to be sealed inside of the hollow part, and when the pen core penetrates into the second opening joint part, the pen core extends to the outside of the hollow part ready for writing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
