<P>PROBLEM TO BE SOLVED: To provide a ball point pen, which is inexpensive and can easily execute a pressurizing operation in the use of an ink for correcting a clerical error o the like with no troublesomeeness such as the necessity of agitation of the ink easily breakable at its initial writing and the pressing of the side of a container. <P>SOLUTION: In a pressurizing type ball point pen having a ball point pen tip at the tip of a barrel and the ink and a follower, which follows the rear end of the ink providing at the rear of the barrel and, in addition, a pressurizing mechanism providing at the rear of the follower, the pressurizing mechanism is formed by arranging a weight behind the follower in the barrel movably back and forth in the barrel under the state without being abutted against the follower. When the weight advances towards the side of the follower by means of its inertial force caused by the shaking of the barrel, a space between the front end of the weight and the rear end of the follower is compressed/pressurized, allowing to back up the fluidity of the ink towards the side of the tip. When the weight moves towards the rear end side of the barrel, the space between the front end of the weight and the rear end of the follower is brought into a state communicating with open air. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
