| 20110274478 | CONICAL NIB AND WRITING INSTRUMENT INCORPORATING THE SAME - A nib of a writing instrument is made of a carbon-resin mixture obtained by mixing a plastic material with carbon fiber. An ink feed core is provided with a nib cover. The nib cover is disposed on an outer periphery of the ink feed core between the nib and the ink feed core. The nib cover is configured to closely adhere at least to an inner periphery of the nib at the tip of the nib. A space defined between the nib and the ink feed core is filled up with the nib cover. The nib is made of a carbon-resin mixture obtained by mixing a plastic material with carbon fiber. With this configuration, a nib having high wear resistance can be obtained and duration of the nib and the writing instrument can be prolonged. | 11-10-2011 |
| 401232000 | With flow-regulator | 2 |
| 20120107036 | WRITING PEN WITH INK STORAGE - A writing pen with ink storage is provided, including a writing nib, an ink storage compartment for storing ink, an ink inducing device for inducing ink into the writing nib, wherein the writing pen further includes an air pressure balancing plug which is plugged in an open end of the ink storage compartment to seal ink, and a breathable core having nanopores, the breathable core being inserted into the air pressure balancing plug with one end extending into ink and the other end communicating with ambient air. The writing pen with ink storage of the present patent application has simple structure, provides fluent writing and no ink leakage. | 05-03-2012 |

| 20090297250 | PEN CAP AND PEN BARREL COUPLING STRUCTURE - A pen cap and a pen barrel coupling structure provides the pen cap formed in hollow to hold a magnet and an opening at one end and the pen barrel couplable with the opening of the pen cap and having a metal element attractable to the magnet. The pen cap and pen barrel have respectively a first coupling portion and a second coupling portion that correspond to and engageable with each other. The first and second coupling portions form a first coupling position to allow the magnet and metal element attracting to each other to form an anchor condition, and a second coupling position to separate the magnet and metal element to release the anchor condition. Thus by moving the pen cap against the pen barrel to the second coupling position, the pen cap can be separated from the pen barrel to make use of the pen easier. | 12-03-2009 |
