Background
In daily study and work activities, ball pens, sign pens and the like used for writing all take out writing ink by rolling a ball at the front end of a pen point or a refill to finish the writing process. In the practical use process, the problems of no ink discharge and unsmooth writing of the ball-point pen and the sign pen after being unsealed and used are often caused by the change of the external climate environment. However, the failure of writing ink and writing fluid is mainly affected by two factors: firstly, the temperature of the external environment is high, when the ball-point pen and the sign pen stop writing for a period of time, the ink is static for a long time, and the ink at the ball point of the pen point is dried and solidified, so that blockage is caused; secondly, the temperature of the external environment is low, and the pen point and the ink in the pen core are condensed at low temperature and cannot flow. At present, people meet the situations, the only way is to replace a new unopened refill, and as the new unopened refill is shipped out, the pen point and the refill are packaged by adopting oil wax, and the oil wax can isolate the ink from the outside air within a certain time, so that the ink is prevented from contacting with the outside air, and the phenomena of ink solidification, condensation and drying can be reduced. The reason why the pen core in the quality guarantee period can write more smoothly after being unsealed; after the pen is unsealed for a period of time, the faults of no ink discharge and unsmooth writing are easy to occur. At the present stage, people still have no ideal solution for the frequent faults of ball-point pens and sign pens and the stranded operators, and the writing experience can be improved only by continuously replacing new pen cores.
